    Description

    TECHNICAL FIELD



    [0001] This application relates to the field of communications technologies, and in particular, to a method for positioning a pico remote radio unit and a system for positioning a pico remote radio unit.

    BACKGROUND



    [0002] With continuous enhancement of indoor digitalization and increasing requirements on indoor capacity, operators continuously enhance indoor deep coverage, and more pico remote radio units (Pico Remote Radio Unit, PRRU) are applied indoors. For installation aesthetics, a home owner requires the PRRUs to be installed inside a suspended ceiling. After the installation is completed, in a routine maintenance phase, maintenance personnel cannot accurately find the PRRUs when the PRRUs are faulty. When installing the PRRUs based on a design drawing, construction personnel usually do not precisely mark actual installation positions due to skill and engineering delivery scope problems. There are numerous PRRUs. Therefore, even if the design drawing is available, a PRRU installed at an actual specific position cannot be known. Therefore, the maintenance personnel cannot find the PRRUs when needing to subsequently maintain the PRRUs.

    [0003] In an existing method, during construction on the site, a wireless deployment tool (wireless deployment tool, WDT) is used to scan an electronic serial number (Electronic Serial Number, ESN) of a PRRU and bind the ESN and a position. Specifically, an engineering design drawing is imported into the WDT. During construction, an engineering team or a supervisor scans an ESN of an installed PRRU based on an actual installation position of the PRRU, and manually binds the ESN and the position on the WDT. After installation of all PRRUs is completed, bound position information of the PRRUs is imported into a U2000 network management system for use.

    [0004] However, the following problems exist when the ESN of the PRRU is scanned and is bound to the position of the PRRU during construction on the site: Different construction teams are responsible for different sites, and there may be a plurality of construction parties on a same site. Each site needs special training, and consequently, it is difficult to extend a contract scope. A plurality of engineering teams simultaneously perform construction, and if the collection is performed by the engineering teams, a contract scope problem is caused and costs need to be increased. An engineering team is low-skilled, and consequently, errors are easily introduced during the collection, and whether information is accurately collected cannot be checked. The WDT has a requirement on a terminal. However, existing terminals of the engineering teams are different, which increases the costs. If the scanning and binding are both performed by a supervisor, considering a bottleneck that one supervisor corresponds to a plurality of engineering teams, an engineering team may have already completed installation when the supervisor needs to perform scanning, so that the scanning cannot be performed. Consequently, it is still difficult to accurately obtain a position of a PRRU, and subsequent efficient operation and maintenance on the indoor system is affected.

    [0005] US 2015/038160 A1 describes a method of manufacture to determine a base station location.

    SUMMARY



    [0006] This application provides a method for positioning a pico remote radio unit and a system for positioning a pico remote radio unit. Drive test information on a terminal side and drive test information on a network management system side are recorded when a drive test is performed, and pico remote radio unit position information and a pico remote radio unit identifier are automatically associated and bound based on the drive test information on the terminal side and the drive test information on the network management system side, to facilitate positioning of a pico remote radio unit, and ensure efficient system operation and maintenance.

    [0007] According to a first aspect of this application, a method for positioning a pico remote radio unit is provided, where the method is applied to a system for positioning a pico remote radio unit, the system for positioning a pico remote radio unit includes at least one pico remote radio unit, a drive test terminal, and a network management system server, and the method includes:

    when the drive test terminal performs a drive test, obtaining, by the drive test terminal, drive test information that is on a terminal side and that is of a drive test event, where the drive test event occurs at least once;

    obtaining, by the network management system server, drive test information that is on a network management system side and that is of the drive test event, where the drive test information on the network management system side includes a pico remote radio unit corresponding to the drive test event;

    obtaining, by the network management system server, a pico remote radio unit identifier based on the measurement information on the network management system side; and

    obtaining, by the network management system server based on the measurement information on the network management system side and the drive test information on the terminal side, pico remote radio unit position information bound to the pico remote radio unit identifier.



    [0008] The measurement information on the terminal side includes a measurement event identifier and the pico remote radio unit position information, and
    the obtaining, by the drive test terminal, drive test information that is on a terminal side and that is of a drive test event includes:

    obtaining, by the drive test terminal, pico remote radio unit layout information by using a pico remote radio unit design drawing;

    obtaining, by the drive test terminal, the pico remote radio unit and the measurement event identifier of the drive test event;

    determining, by the drive test terminal, the pico remote radio unit position information based on the pico remote radio unit and the pico remote radio unit layout information; and

    obtaining, by the drive test terminal, the measurement information on the terminal side based on the measurement event identifier and the pico remote radio unit position information.



    [0009] When a user performs the drive test by using the drive test terminal, in a drive test process, the user performs a fixed point measurement at different positions when walking. Therefore, the drive test event occurs one after another. In addition, each time performing the drive test event, the drive test terminal temporarily accesses one pico remote radio unit. During the test or after the test is completed, the drive test terminal obtains the drive test information that is on the terminal side and that is of the drive test event at this time. The drive test event occurs not only once, but also may occur a plurality of times. Each time performing the drive test event, the drive test terminal temporarily accesses one pico remote radio unit, and the network management system server is connected to the pico remote radio unit, so that the network management system server may further obtain the drive test information that is on the network management system side and that corresponds to the drive test event, and the pico remote radio unit corresponding to the drive test event is also recorded in the drive test information on the network management system side. The obtained measurement information on the network management system side includes the pico remote radio unit corresponding to the drive test event. When already known the pico remote radio unit, the network management system server can obtain, by using a network, or preset the pico remote radio unit identifier corresponding to the pico remote radio unit. In each drive test event, the drive test terminal accesses one pico remote radio unit, so that the drive test terminal can automatically record, in the drive test information on the terminal side, a position of the pico remote radio unit to which the drive test event belongs, or record, in the drive test information on the terminal side, an indoor position of the drive test terminal. The pico remote radio unit position information can be obtained through calculation based on the measurement information on the network management system side and the drive test information on the terminal side that are of one drive test event, and positioning of the pico remote radio unit is implemented by binding the pico remote radio unit identifier and the pico remote radio unit position information. Compared with a solution in which during construction on the site, the pico remote radio unit identifier of the pico remote radio unit is scanned and is bound to the pico remote radio unit position information, this solution does not need a construction team to scan on the site. The scanning can be subsequently completed in the drive test process of the drive test terminal. The information is collected in an engineering standardized action, and automatic binding of the position is completed, to facilitate positioning of the pico remote radio unit. In addition, there are a plurality of pico remote radio units indoors, and some are installed inside a ceiling. An installation position of a faulty pico remote radio unit cannot be rapidly found. The pico remote radio unit position information and the pico remote radio unit identifier are automatically associated and bound based on the drive test information on the terminal side and the drive test information on the network management system side, to ensure efficient system operation and maintenance.

    [0010] In a construction phase, if an installation position of the pico remote radio unit has already been designed, the pico remote radio unit design drawing includes the pico remote radio unit layout information. When the drive test terminal performs the drive test process, in each drive test event, the drive test terminal temporarily accesses one pico remote radio unit, so that the drive test terminal can obtain the measurement event identifier and the pico remote radio unit at this time. The measurement event identifier includes a TMSI and a time stamp. Each time the drive test terminal accesses the pico remote radio unit, only one call is initiated. Therefore, each access generates one unique TMSI. The time stamp means a time in which the drive test terminal performs each drive test event. The TMSI and the time stamp can uniquely indicate one drive test event of the drive test terminal. In each drive test event, the drive test terminal knows the accessed pico remote radio unit. When already known the pico remote radio unit layout information, the drive test terminal can determine the pico remote radio unit position information of the pico remote radio unit in each drive test event. The drive test terminal combines the obtained pico remote radio unit position information and the measurement event identifier including the TMSI and the time stamp as the measurement information on the terminal side.

    [0011] With reference to the first aspect of this application, in a first implementation of the first aspect of this application, the obtaining, by the network management system server, a pico remote radio unit identifier based on the measurement information on the network management system side includes:

    obtaining, by the network management system server, the pico remote radio unit corresponding to the drive test event by parsing the measurement information on the network management system side; and

    obtaining, by the network management system server, the pico remote radio unit identifier of the pico remote radio unit based on preset pico remote radio unit configuration information and inventory information.



    [0012] Each time performing the drive test event, the drive test terminal temporarily accesses one pico remote radio unit, and the network management system server is connected to the pico remote radio unit, so that the network management system server may further obtain the drive test information that is on the network management system side and that corresponds to the drive test event, the pico remote radio unit corresponding to the drive test event is recorded in the drive test information on the network management system side, and the TMSI and the time stamp that are of the drive test event are also recorded in the drive test information on the network management system side. The network management system server can obtain the pico remote radio unit corresponding to each drive test event by parsing the measurement information on the network management system side. The network management system server can learn of, based on the preset pico remote radio unit configuration information and inventory information, the pico remote radio unit identifier corresponding to each pico remote radio unit, and can obtain the pico remote radio unit identifier of the pico remote radio unit through matching.

    [0013] With reference to the first implementation of the first aspect of this application, in a second implementation of the first aspect of this application, the drive test information on the network management system side further includes the measurement event identifier, and
    the obtaining, by the network management system server based on the measurement information on the network management system side and the drive test information on the terminal side, pico remote radio unit position information corresponding to the pico remote radio unit identifier includes:

    associating, by the network management system server, the measurement information on the network management system side and the drive test information on the terminal side based on the measurement event identifier;

    obtaining, by the network management system server, the pico remote radio unit position information by parsing the drive test information on the terminal side, and obtaining the pico remote radio unit identifier by parsing the measurement information on the network management system side; and

    binding, by the network management system server, the pico remote radio unit identifier and the pico remote radio unit position information based on a preset binding algorithm.



    [0014] In each drive test event, the TMSI and the time stamp are recorded in both the measurement information on the network management system side and the drive test information on the terminal side, so that the measurement information on the network management system side and the drive test information on the terminal side are associated based on the TMSI and the time stamp. When already known that the drive test information on the terminal side includes the pico remote radio unit position information, the network management system server obtains the pico remote radio unit position information by parsing the drive test information on the terminal side. The network management system server binds the pico remote radio unit identifier and the pico remote radio unit position information by using the preset binding algorithm. Different preset binding algorithms need to be used based on different cases, and may specifically include the following three types: (1) a pico remote radio unit position adjacent relationship binding algorithm; (2) an iteration binding algorithm; and (3) a drive test adjacent relationship binding algorithm.

    [0015] According to a second aspect of this application, a system for positioning a pico remote radio unit is provided, including:

    at least one pico remote radio unit, a drive test terminal, and a network management system server, where

    the drive test terminal is configured to: when performing a drive test, obtain drive test information that is on a terminal side and that is of a drive test event, where the drive test event occurs at least once;

    the network management system server is configured to obtain drive test information that is on a network management system side and that is of the drive test event, where the drive test information on the network management system side includes a pico remote radio unit corresponding to the drive test event;

    the network management system server is further configured to obtain a pico remote radio unit identifier based on the measurement information on the network management system side; and

    the network management system server is further configured to obtain, based on the measurement information on the network management system side and the drive test information on the terminal side, pico remote radio unit position information bound to the pico remote radio unit identifier.



    [0016] The measurement information on the terminal side includes a measurement event identifier and the pico remote radio unit position information, and

    the drive test terminal is specifically configured to obtain pico remote radio unit layout information by using a pico remote radio unit design drawing;

    the drive test terminal is further configured to obtain the pico remote radio unit and the measurement event identifier of the drive test event;

    the drive test terminal is further configured to determine the pico remote radio unit position information based on the pico remote radio unit and the pico remote radio unit layout information; and

    the drive test terminal is further configured to obtain the measurement information on the terminal side based on the measurement event identifier and the pico remote radio unit position information.



    [0017] When a user performs the drive test by using the drive test terminal, in a drive test process, the user performs a fixed point measurement at different positions when walking. Therefore, the drive test event occurs one after another. In addition, each time performing the drive test event, the drive test terminal temporarily accesses one pico remote radio unit.

The pico remote radio unit position information can be obtained through calculation based on the measurement information on the network management system side and the drive test information on the terminal side that are of one drive test event, and positioning of the pico remote radio unit is implemented by binding the pico remote radio unit identifier and the pico remote radio unit position information.

    DESCRIPTION OF EMBODIMENTS



    [0026] This application provides a method for positioning a pico remote radio unit and a system for positioning a pico remote radio unit. Drive test information on a terminal side and drive test information on a network management system side are recorded when a drive test is performed, and pico remote radio unit position information and a pico remote radio unit identifier are automatically associated and bound based on the drive test information on the terminal side and the drive test information on the network management system side, to facilitate positioning of a pico remote radio unit, and ensure efficient system operation and maintenance.

    [0027] The following clearly and completely describes technical solutions in this application with reference to the accompanying drawings in this application. Apparently, the described embodiments are merely some rather than all of embodiments of this application. All other embodiments obtained by persons skilled in the art based on the embodiments of this application without creative efforts shall fall within the protection scope of this application.

    [0028] First, a system architecture or a scenario to which this application is applied is briefly described.

    [0029] FIG. 1 is a schematic diagram of a system architecture or a scenario in this application. A drive test terminal is an electronic device with a communication function, and may be specifically a mobile phone or the like. In a drive test process, the drive test terminal may be connected to a network management system server by using one of a plurality of PRRUs indoors. When performing a drive test by using the drive test terminal, a user can move and perform a fixed point measurement at different positions. Each measurement is referred to as one drive test event.

    [0030] With reference to FIG. 2, based on the foregoing descriptions, an embodiment of this application provides a method for positioning a pico remote radio unit, including the following steps.

    [0031] 201. The drive test terminal obtains drive test information that is on a terminal side and that is of the drive test event.

    [0032] In this embodiment, when a user performs the drive test by using the drive test terminal, in the drive test process, the user performs a fixed point measurement at different positions when walking. Therefore, the drive test event occurs one after another. In addition, each time performing the drive test event, the drive test terminal temporarily accesses one pico remote radio unit (PRRU). During the test or after the test is completed, the drive test terminal obtains the drive test information that is on the terminal side and that is of the drive test event at this time. The drive test event occurs not only once, but also may occur a plurality of times.

    [0033] 202. The network management system server obtains drive test information that is on a network management system side and that is of the drive test event.

    [0034] In this embodiment, each time performing the drive test event, the drive test terminal temporarily accesses one PRRU, and the network management system server is connected to the PRRU, so that the network management system server may further obtain the drive test information that is on the network management system side and that corresponds to the drive test event, and the PRRU corresponding to the drive test event is also recorded in the drive test information on the network management system side.

    [0035] 203. The network management system server obtains a pico remote radio unit identifier based on the measurement information on the network management system side.

    [0036] In this embodiment, the obtained measurement information on the network management system side includes the PRRU corresponding to the drive test event. When already known the PRRU, the network management system server can obtain, by using a network, or preset the pico remote radio unit identifier corresponding to the PRRU. The pico remote radio unit identifier may be specifically an equipment serial number (equipment serial number, ESN), and the ESN is used as a unique identifier of the PRRU.

    [0037] 204. The network management system server obtains, based on the measurement information on the network management system side and the drive test information on the terminal side, pico remote radio unit position information bound to the pico remote radio unit identifier.

    [0038] In this embodiment, in each drive test event, the drive test terminal accesses one PRRU, so that when already known PRRU layout information during construction of the PRRU, the drive test terminal can automatically record, in the drive test information on the terminal side, a position of the PRRU to which the drive test event belongs, or record, in the drive test information on the terminal side, an indoor position of the drive test terminal. The PRRU position information can be obtained through calculation based on the measurement information on the network management system side and the drive test information on the terminal side that are of one drive test event, and positioning of the PRRU is implemented by binding the ESN and the PRRU position information. Certainly, a PRRU already positioned does not need to be positioned again.

    [0039] In this embodiment of this application, compared with a solution in which during construction on the site, the ESN of the PRRU is scanned and is bound to the position of the PRRU, this solution does not need a construction team to scan on the site. The scanning can be subsequently completed in the drive test process of the drive test terminal. The information is collected in an engineering standardized action, and automatic binding of the position is completed, to facilitate positioning of the PRRU. In addition, there are a plurality of PRRUs indoors, and some are installed inside a ceiling. An installation position of a faulty PRRU cannot be rapidly found. The PRRU position information and the PRRU identifier are automatically associated and bound based on the drive test information on the terminal side and the drive test information on the network management system side, to ensure efficient system operation and maintenance.

    [0040] In the foregoing embodiment, the PRRU position information may already be determined based on a PRRU design drawing during the construction, or a situation of the PRRU position information may be unknown. In this case, positioning of a specific PRRU can be implemented in the following two manners. Descriptions are shown in detail in the following by using embodiments.

    [0041] 1. With reference to FIG. 3, an embodiment of this application provides a method for positioning a pico remote radio unit, including the following steps.

    [0042] 301. The drive test terminal obtains pico remote radio unit layout information by using a pico remote radio unit design drawing.

    [0043] In this embodiment, in a construction phase, if an installation position of the PRRU has already been designed, the PRRU design drawing includes the PRRU layout information.

    [0044] 302. The drive test terminal obtains the pico remote radio unit and a measurement event identifier of the drive test event.

    [0045] In this embodiment, when the drive test terminal performs the drive test process, in each drive test event, the drive test terminal temporarily accesses one PRRU, so that the drive test terminal can obtain the measurement event identifier and the PRRU at this time. The measurement event identifier includes a temporary mobile subscriber identity (temporary mobile subscriber identity, TMSI) and a time stamp. Each time the drive test terminal accesses the PRRU, only one call is initiated. Therefore, each access generates one unique TMSI. The time stamp means a time in which the drive test terminal performs each drive test event. The TMSI and the time stamp can uniquely indicate one drive test event of the drive test terminal.

    [0046] 303. The drive test terminal determines the pico remote radio unit position information based on the pico remote radio unit and the pico remote radio unit layout information.

    [0047] In this embodiment, in each drive test event, the drive test terminal knows the accessed PRRU. When already known the PRRU layout information, the drive test terminal can determine the PRRU position information of the PRRU in each drive test event.

    [0048] 304. The drive test terminal obtains the measurement information on the terminal side based on the measurement event identifier and the pico remote radio unit position information.

    [0049] In this embodiment, the drive test terminal combines the obtained PRRU position information and the measurement event identifier including the TMSI and the time stamp as the measurement information on the terminal side.

    [0050] 305. The network management system server obtains the drive test information that is on the network management system side and that is of the drive test event.

    [0051] In this embodiment, each time performing the drive test event, the drive test terminal temporarily accesses one PRRU, and the network management system server is connected to the PRRU, so that the network management system server may further obtain the drive test information that is on the network management system side and that corresponds to the drive test event, the PRRU corresponding to the drive test event is recorded in the drive test information on the network management system side, and the TMSI and the time stamp that are of the drive test event are also recorded in the drive test information on the network management system side.

    [0052] 306. The network management system server obtains the pico remote radio unit corresponding to the drive test event by parsing the measurement information on the network management system side.

    [0053] In this embodiment, the network management system server can obtain the PRRU corresponding to each drive test event by parsing the measurement information on the network management system side.

    [0054] 307. The network management system server obtains the pico remote radio unit identifier of the pico remote radio unit based on preset pico remote radio unit configuration information and inventory information.

    [0055] In this embodiment, the network management system server can learn of, based on the preset PRRU configuration information and inventory information, the ESN corresponding to each PRRU, and can obtain the ESN of the PRRU through matching.

    [0056] 308. The network management system server associates the measurement information on the network management system side and the drive test information on the terminal side based on the measurement event identifier.

    [0057] In this embodiment, in each drive test event, the TMSI and the time stamp are recorded in both the measurement information on the network management system side and the drive test information on the terminal side, so that the measurement information on the network management system side and the drive test information on the terminal side are associated based on the TMSI and the time stamp.

    [0058] 309. The network management system server obtains the pico remote radio unit position information by parsing the drive test information on the terminal side.

    [0059] In this embodiment, when already known that the drive test information on the terminal side includes the PRRU position information, the network management system server obtains the PRRU position information by parsing the drive test information on the terminal side.

    [0060] 310. The network management system server binds the pico remote radio unit identifier and the pico remote radio unit position information based on a preset binding algorithm.

    [0061] In this embodiment, the network management system server binds the pico remote radio unit identifier and the pico remote radio unit position information by using the preset binding algorithm. Different preset binding algorithms need to be used based on different cases, and may specifically include the following three types: (1) a PRRU position adjacent relationship binding algorithm; (2) an iteration binding algorithm; and (3) a drive test adjacent relationship binding algorithm. Descriptions are provided in the following:
    1. (1) Drive test data of the pico remote radio unit may be lost due to a problem in a drive test line (for example, because a user cannot walk indoors). When a quantity of drive test events is not sufficient and cannot reach a specific threshold, position information of some PRRUs fails to be bound to ESNs. In this case, the PRRU position adjacent relationship binding algorithm can be used. As shown in FIG. 4, an iteration is sequentially performed on unbound ESNs, an ESN, adjacent to the unbound ESN, in an already bound ESN set (in FIG. 4, 0_129_1 is adjacent to 0_132_1 are, and 0_130_1, is adjacent to 0_131_1) is obtained based on a signal strength relationship, and the unbound ESN is bound to an unbound PRRU position based on an already bound PRRU position and a position of the drive test event.
    2. (2) A PRRU signal fluctuates greatly and is easily affected by floors (when an upper floor and a lower floor are in a same cell). Therefore, drive test event points around the position of the PRRU are inconsistent with actual ESNs. As shown in FIG. 6, a PRRU 1 is interfered by 0_134_1, 0_136_1, and 0_90_1 (cross-floor ESNs); and a PRRU 3 is interfered by 0_136_1. Therefore, impact of an interfering drive test event point may be eliminated by using an inter-floor iteration binding algorithm or a cross-floor iteration binding algorithm. As shown in FIG. 5, first, one drive test event point is used to calculate a Euclidean distance with all PRRU positions, and all drive test event points are calculated in a same manner one by one. FIG. 6 shows a result of iteration binding: To meet two thresholds: one is that a quantity of successful binding times is five, the other is that a correct binding rate is 80%, a sequence of the iteration binding is a PRRU 2, a PRRU 1, and a PRRU 3.
    3. (3) If PRRUs are excessively close to each other, and when a PRRU signal is blocked by drive test personnel, drive test event points with a same ESN around a PRRU point position tend to be located on one side, and a quantity of drive test event points are relatively small. As shown in FIG. 7, drive test point position data of 0 _131_1 and 0_132_1 are respectively on left sides of a PRRU 2 and a PRRU 3. In this case, impact of an interfering drive test event point may be eliminated by using the drive test adjacent relationship binding algorithm, and an unbound PRRU position and an occurrence order of ESNs (which are 0_130_1, 0_131_1, and 0_132_1 in FIG. 7) are determined based on a sequence of drive test events, to sequentially bind the PRRU 2 and the PRRU 3 with their corresponding ESNs.


    [0062] 2. With reference to FIG. 8, an embodiment of this application provides a method for positioning a pico remote radio unit, including the following steps.

    [0063] 801. The drive test terminal obtains the pico remote radio unit and a measurement event identifier of the drive test event.

    [0064] In this embodiment, if the PRRU design drawing has been lost after the construction, when the drive test terminal performs the drive test process, in each drive test event, the drive test terminal temporarily accesses one PRRU, so that the drive test terminal can obtain the measurement event identifier and the PRRU at this time. The measurement event identifier includes a TMSI and a time stamp. Each time the drive test terminal accesses the PRRU, only one call is initiated. Therefore, each access generates one unique TMSI. The time stamp means a time in which the drive test terminal performs each drive test event. The TMSI and the time stamp can uniquely indicate one drive test event of the drive test terminal.

    [0065] 802. The drive test terminal obtains the measurement information on the terminal side based on the measurement event identifier.

    [0066] In this embodiment, the drive test terminal combines the obtained PRRU position information and the measurement event identifier including the TMSI and the time stamp as the measurement information on the terminal side.

    [0067] 803. The network management system server obtains the drive test information that is on the network management system side and that is of the drive test event.

    [0068] In this embodiment, each time performing the drive test event, the drive test terminal temporarily accesses one PRRU, and the network management system server is connected to the PRRU, so that the network management system server may further obtain the drive test information that is on the network management system side and that corresponds to the drive test event, the PRRU corresponding to the drive test event is recorded in the drive test information on the network management system side, the TMSI and the time stamp that are of the drive test event are recorded in the drive test information on the network management system side, and a receive level of the PRRU corresponding to the drive test event when the PRRU receives a signal of the drive test terminal is also recorded in the drive test information on the network management system side.

    [0069] 804. The network management system server associates the measurement information on the network management system side and the drive test information on the terminal side based on the measurement event identifier.

    [0070] In this embodiment, in each drive test event, the TMSI and the time stamp are recorded in both the measurement information on the network management system side and the drive test information on the terminal side, so that the measurement information on the network management system side and the drive test information on the terminal side are associated based on the TMSI and the time stamp.

    [0071] 805. The network management system server obtains terminal position information by parsing the drive test information on the terminal side, and obtains the receive level of the pico remote radio unit and the pico remote radio unit identifier by parsing the measurement information on the network management system side.

    [0072] In this embodiment, the network management system server obtains the terminal position information by parsing the drive test information on the terminal side, and obtains the receive level of the PRRU and the ESN by parsing the measurement information on the network management system side.

    [0073] 806. The network management system server obtains the pico remote radio unit position information through calculation by using a field strength positioning algorithm and based on the terminal position information and the receive level of the pico remote radio unit.

    [0074] In this embodiment, the network management system server obtains the PRRU position information, through calculation by using a field strength positioning algorithm and based on the terminal position information and the receive level of the pico remote radio unit.

    [0075] 807. The network management system server binds the pico remote radio unit identifier and the pico remote radio unit position information.

    [0076] In this embodiment, the network management system server binds the pico remote radio unit identifier and the pico remote radio unit position information.

    [0077] In this embodiment of this application, the PRRU position information calculated by using the positioning algorithm may have some errors. However, the errors can be smoothed and precision can be improved by controlling a quantity of sampling points and using the fixed point measurement. The PRRU position information is used for device maintenance, which is much better than no PRRU position information.

    [0078] With reference to FIG. 9, an embodiment of this application provides a system for positioning a pico remote radio unit, including the following steps.

    at least one pico remote radio unit 901, a drive test terminal 902, and a network management system server 903, where

    the drive test terminal 902 is configured to: when performing a drive test, obtain drive test information that is on a terminal side and that is of a drive test event, where the drive test event occurs at least once;

    the network management system server 903 is configured to obtain drive test information that is on a network management system side and that is of the drive test event, where the drive test information on the network management system side includes a pico remote radio unit 901 corresponding to the drive test event;

    the network management system server 903 is further configured to obtain a pico remote radio unit identifier based on the measurement information on the network management system side; and

    the network management system server 903 is further configured to obtain, based on the measurement information on the network management system side and the drive test information on the terminal side, pico remote radio unit position information bound to the pico remote radio unit identifier.



    [0079] In this embodiment of this application, when a user performs the drive test by using the drive test terminal 902, in a drive test process, the user performs a fixed point measurement at different positions when walking. Therefore, the drive test event occurs one after another. In addition, each time performing the drive test event, the drive test terminal 902 temporarily accesses one pico remote radio unit 901. During the test or after the test is completed, the drive test terminal 902 obtains the drive test information that is on the terminal side and that is of the drive test event at this time. The drive test event occurs not only once, but also may occur a plurality of times. Each time performing the drive test event, the drive test terminal 902 temporarily accesses one pico remote radio unit 901, and the network management system server 903 is connected to the pico remote radio unit 901, so that the network management system server 903 may further obtain the drive test information that is on the network management system side and that corresponds to the drive test event, and the pico remote radio unit 901 corresponding to the drive test event is also recorded in the drive test information on the network management system side. The obtained measurement information on the network management system side includes the pico remote radio unit 901 corresponding to the drive test event. When already known the pico remote radio unit 901, the network management system server 903 can obtain, by using a network, or preset the pico remote radio unit identifier corresponding to the pico remote radio unit 901. In each drive test event, the drive test terminal 902 accesses one pico remote radio unit 901, so that the drive test terminal 902 can automatically record, in the drive test information on the terminal side, a position of the pico remote radio unit 901 to which the drive test event belongs, or record, in the drive test information on the terminal side, an indoor position of the drive test terminal 902. The pico remote radio unit position information can be obtained through calculation based on the measurement information on the network management system side and the drive test information on the terminal side that are of one drive test event, and positioning of the pico remote radio unit is implemented by binding the pico remote radio unit identifier and the pico remote radio unit position information. Compared with a solution in which during construction on the site, the pico remote radio unit identifier of the pico remote radio unit is scanned and is bound to the pico remote radio unit position information, this solution does not need a construction team to scan on the site. The scanning can be subsequently completed in the drive test process of the drive test terminal 902. The information is collected in an engineering standardized action, and automatic binding of the position is completed, to facilitate positioning of the pico remote radio unit. In addition, there are a plurality of pico remote radio units indoors, and some are installed inside a ceiling. An installation position of a faulty pico remote radio unit cannot be rapidly found. The pico remote radio unit position information and the pico remote radio unit identifier are automatically associated and bound based on the drive test information on the terminal side and the drive test information on the network management system side, to ensure efficient system operation and maintenance.

    [0080] Optionally, in some embodiments of this application, the measurement information on the terminal side includes a measurement event identifier and the pico remote radio unit position information, and

    the drive test terminal 902 is further configured to obtain the measurement information on the terminal side based on the measurement event identifier and the pico remote radio unit position information.



    [0081] In this embodiment of this application, in a construction phase, if an installation position of the pico remote radio unit 901 has already been designed, the pico remote radio unit design drawing includes the pico remote radio unit layout information. When the drive test terminal 902 performs the drive test process, in each drive test event, the drive test terminal 902 temporarily accesses one pico remote radio unit 901, so that the drive test terminal can obtain the measurement event identifier and the pico remote radio unit 901 at this time. The measurement event identifier includes a TMSI and a time stamp. Each time the drive test terminal 902 accesses the pico remote radio unit 901, the drive test terminal only one call is initiated. Therefore, each access generates one unique TMSI. The time stamp means a time in which the drive test terminal 902 performs each drive test event. The TMSI and the time stamp can uniquely indicate one drive test event of the drive test terminal 902. In each drive test event, the drive test terminal 902 knows the accessed pico remote radio unit 901. When already known the pico remote radio unit layout information, the drive test terminal can determine the pico remote radio unit position information of the pico remote radio unit 901 in each drive test event. The drive test terminal 902 combines the obtained pico remote radio unit position information and the measurement event identifier including the TMSI and the time stamp as the measurement information on the terminal side.

The network management system server 903 can obtain the pico remote radio unit 901 corresponding to each drive test event by parsing the measurement information on the network management system side. The network management system server 903 can learn of, based on the preset pico remote radio unit configuration information and inventory information, the pico remote radio unit identifier corresponding to each pico remote radio unit 901, and can obtain the pico remote radio unit identifier of the pico remote radio unit 901 through matching.

    the network management system server 903 is further configured to bind the pico remote radio unit identifier and the pico remote radio unit position information based on a preset binding algorithm.



    [0085] In this embodiment of this application, in each drive test event, the TMSI and the time stamp are recorded in both the measurement information on the network management system side and the drive test information on the terminal side, so that the measurement information on the network management system side and the drive test information on the terminal side are associated based on the TMSI and the time stamp. When already known that the drive test information on the terminal side includes the pico remote radio unit position information, the network management system server 903 obtains the pico remote radio unit position information by parsing the drive test information on the terminal side. The network management system server 903 binds the pico remote radio unit identifier and the pico remote radio unit position information by using the preset binding algorithm. Different preset binding algorithms need to be used based on different cases, and may specifically include the following three types: (1) a pico remote radio unit position adjacent relationship binding algorithm; (2) an iteration binding algorithm; and (3) a drive test adjacent relationship binding algorithm.

    [0087] In this embodiment of this application, if the pico remote radio unit design drawing has been lost after the construction, when the drive test terminal 902 performs the drive test process, in each drive test event, the drive test terminal 902 temporarily accesses one pico remote radio unit 901, so that the drive test terminal can obtain the measurement event identifier and the pico remote radio unit 901 at this time. The measurement event identifier includes the TMSI and the time stamp. Each time the drive test terminal 902 accesses the pico remote radio unit 901, only one call is initiated. Therefore, each access generates one unique TMSI. The time stamp means a time in which the drive test terminal 902 performs each drive test event.
