DESCRIPTION OF EMBODIMENTS



[0012] The following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this disclosure without creative efforts shall fall within the protection scope of this disclosure.

[0013] The term "include" and any other variants in the specification and claims of this application mean to cover the non-exclusive inclusion, for example, a process, method, system, product, or device that includes a list of steps or units is not necessarily limited to those steps or units, but may include other steps or units not expressly listed or inherent to such a process, method, product, or device. In addition, "and/or" used in the specification and claims means at least one of the connected objects. For example, A and/or B represents the following three cases: Only A exists, only B exists, and both A and B exist.

[0014] In the embodiments of the present disclosure, the word such as "exemplary" or "example" is used to represent giving an example, an illustration, or a description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this disclosure should not be construed as being more preferred or advantageous than other embodiments or design schemes. To be precise, the use of the term such as "exemplary" or "for example" is intended to present a related concept in a specific manner.

[0015] The technology described in this specification is not limited to the 5th-generation (5th-generation, 5G) system and subsequent evolved communication systems as well as LTE/LTE-advanced (LTE-Advanced, LTE-A) systems, and can also be applied to various wireless communication systems such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), and single-carrier frequency-division multiple access (Single-carrier Frequency-Division Multiple Access, SC-FDMA) systems, and other systems.

[0016] The terms "system" and "network" are usually used interchangeably. A CDMA system may implement a radio technology such as CDMA2000 or universal terrestrial radio access (Universal Terrestrial Radio Access, UTRA). UTRA includes Wideband CDMA (Code Division Multiple Access, WCDMA) and other CDMA variants. A TDMA system can implement radio technologies such as the global system for mobile communications (Global System for Mobile Communication, GSM). An OFDMA system may implement a radio technology such as Ultra Mobile Broadband (Ultra Mobile Broadband, UMB), evolved UTRA (Evolution-UTRA, E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, or Flash-OFDM. UTRA and E-UTRA are a part of Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS). LTE and more advanced LTE (such as LTE-A) are new UMTS versions that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3rd Generation Partnership Project, 3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The technology described in the present disclosure may also be used in the foregoing system and radio technology, and may also be used in another system and radio technology.

[0017] For ease of understanding the embodiments of the present disclosure, the following technical points are described:
  1. 1. MDT
    1. (1) MDT mode
      MDT measurement includes two modes: logged MDT and immediate MDT.
    2. (2) Terminal measurement configuration
      It may be independent of the network for recording target configuration MDT for a terminal, and is a configuration for measuring normal radio resource management (Radio Resource Management, RRM). However, in most cases, the availability of measurement results depends conditionally on the terminal RRM configuration.
    3. (3) Terminal measurement collection and reporting
      MDT measurement records include multiple events and measurements over time. Time interval measurement collection and reporting are decoupled to limit the impact on terminal battery consumption and network signaling load.
    4. (4) Geographical range of measurement records
      The geographic area of defined measurement sets can be collected or configured.
    5. (5) Location information
      Measurement should be associated with available location information and/or other information or measured values, which can be used to derive location information.
    6. (6) Time information
      A measured value in a measurement record should be associated with a time stamp.
    7. (7) Terminal capability information
      A network can use the terminal capability to select a terminal for MDT measurement.
  2. 2. MDT process in the related art
    1. (1) Logged MDT (Logged MDT)
      When a terminal is in an idle (idle) state, the terminal performs MDT measurement according to configuration information of MDT delivered by a network and saves recorded content. When the terminal enters a connected state, it notifies the network that there is MDT data and reports the MDT data to a base station.
    2. (2) Immediate MDT (Immediate MDT)
      The terminal performs MDT measurement in the connected state and immediately reports MDT data to the base station.


[0018] After receiving the MDT data reported by the terminal, the base station can feed it back to the operation administration and maintenance (Operation Administration and Maintenance, OAM) node or other nodes that collect the MDT data.

The communications device 12 may be recorded as UE, and can communicate with (transmit signaling or data to) the network device 10 and the network device 11. In actual application, a connection between the devices is a wireless connection. For ease of visually indicating a connection relationship between the devices, a solid line is used for illustration in FIG. 1.

[0020] The network device 10 and the network device 11 provided in the embodiments of the present disclosure may be base stations, and the base station may be a generally used base station, or may be an evolved node base station (evolved node base station, eNB), or may be a device such as a network device (for example, a next generation node base station (next generation node base station, gNB) or a transmission and reception point (transmission and reception point, TRP)) in a 5G system.

[0021] The communications device provided in this embodiment of the present disclosure may be a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (Ultra-Mobile Personal Computer, UMPC), a netbook, or a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device), an in-vehicle device, or the like.

[0022] The communications device 12 may be a multi-card terminal. For example, the communications device 12 includes a first subscriber identity module (Subscriber Identification Module, SIM) card and a second SIM card. The first SIM card and the second SIM card can share or exchange internal information (for example, configuration information) of the communications device 12. The communications device 12 can access a first network via the first SIM card and can access a second network via the second SIM card. The first network and the second network may be of different network types. For example, the first network is a 5G new radio (new radio, NR) network, and the second network is an LTE network.

[0040] In this embodiment of the present disclosure, after the communications device receives the configuration information of MDT for the UE 1, the UE 1 and the UE 2 can share or exchange information (for example, the configuration information of MDT) of the communications device. In this way, the communications device can perform MDT measurement according to the configuration information of MDT, and record the first measurement result measured for the UE 1 and the second measurement result measured for the UE 2.

[0041] Further, the first measurement result or the second measurement result includes one or more of the following: content of a measurement record and information about an abnormal event.

[0042] It may be understood that storage-related parameters (such as storage quantity and storage time) in the first measurement result and the second measurement result may be configured based on a specific situation.

[0043] According to this embodiment of the present disclosure, for the communications device onto which the at least two UEs are integrated, only the configuration information of MDT for the UE 1 needs to be configured on the network side, and the UE 1 and the UE 2 in the communications device share or exchange the configuration information of MDT, so that the communications device can perform MDT measurement based on the configuration information, and record the first measurement result measured for the UE 1 and the second measurement result measured for the UE 2. In this way, the communications device can record the first measurement result measured for the UE 1 and the second measurement result measured for the UE 2 only by configuring configuration information of MDT once on the network side, which avoids the problem that two cells with which a dual-card terminal is registered need to perform MDT configuration twice for the dual-card terminal, thereby effectively reducing network signaling.

[0044] Referring to FIG. 3, an embodiment of the present disclosure provides a measurement method. The method can be performed by a communications device, the communications device may include at least two user equipments (UEs), the at least two UEs include UE 1 and UE 2, and the method includes steps 301 to 303.

Then, the communications device performs MDT measurement based on the configuration information, and records a first measurement result measured for the first network and a second measurement result measured for a second network. The second network is a network that the communications device accesses via the SIM card 2. The first network and the second network may be of different network types.

[0060] According to this embodiment of the present disclosure, for the communications device onto which the at least two UEs are integrated, only the configuration information of MDT for the UE 1 needs to be configured on the network side, and the UE 1 and the UE 2 in the communications device share or exchange the configuration information of MDT, so that the communications device can perform MDT measurement based on the configuration information, record the first measurement result measured for the UE 1 and the second measurement result measured for the UE 2, and perform direct reporting or perform reporting as instructed by a network. In this way, the communications device can record the first measurement result measured for the UE 1 and the second measurement result measured for the UE 2 only by configuring configuration information of MDT once on the network side, which avoids the problem that two cells with which a dual-card terminal is registered need to perform MDT configuration twice for the dual-card terminal, thereby effectively reducing network signaling.

[0061] This embodiment of the present disclosure further provides a communications device. Because a problem-resolving principle of the communications device is similar to that of the measurement method in this embodiment of the present disclosure, for implementation of the communications device, reference may be made to implementation of the method, and repeated parts are not described.

[0062] Referring to FIG. 4, an embodiment of the present disclosure further provides a communications device. The communications device includes at least two user equipments (UEs), the at least two UEs include UE 1 (not shown in the figure) and UE 2 (not shown in the figure), and the communications device 400 further includes:

a receiving module, configured to receive configuration information of minimization of drive-test (MDT) for the UE 1; and

a measurement record module, configured to perform MDT measurement based on the configuration information, and record a first measurement result measured for the UE 1 and a second measurement result measured for the UE 2.



[0063] In this embodiment of the present disclosure, the communications device is divided into the UE 1 and the UE 2. The UE 1 and the UE 2 are virtual terminals, but not physical terminals. That is, the at least two virtual terminals are integrated onto the communications device. In this way, the communications device can be understood as a multi-card terminal.

[0064] For example, the communications device is a dual-card terminal, and includes a SIM card 1 and a SIM card 2. The communications device registers with a cell 1 via the SIM card 1, and registers with a cell 2 via the SIM card 2. On the network side, for the cell 1, it is considered that the UE 1 is a communications device that accesses the cell 1, and for the cell 2, it is considered that the UE 2 is a communications device that accesses the cell 2.

[0065] Further, the cell 1 and the cell 2 may belong to different networks. For example, the cell 1 is an NR cell, and the cell 2 is an LTE cell.

[0066] Further, the UE 1 and the UE 2 can share or exchange internal information of the dual-card terminal. It may be understood that sharing or exchange of internal information of the dual-card terminal can be performed between the SIM card 1 and the SIM card 2. Sharing means that both the SIM card 1 and the SIM card 2 can obtain internal information (for example, configuration information of MDT) of the dual-card terminal from shared storage space.
