Description

FIELD OF THE INVENTION



[0001] The present invention relates to the communications field, and in particular, to a method, an apparatus, and a system for controlling a self-optimization switch.

BACKGROUND OF THE INVENTION



[0002] In an LTE (Long Term Evolution) system, a SON (Self Organizing Network) technology is used. The SON technology integrates expert's experience and an intelligent technology into an automatic program, and enables the network to automatically collect data, analyze and discover a problem, and perform adjustment. Self-optimization is an instance of the SON.

[0003] In some cases, the self-optimization of the SON is expected to automatically run, automatically optimize network parameters and performance, and so on; and it is expected that a state of the self-optimization can be known at any time, so that complete self-optimization management can be implemented. In other cases (for example, in the case of network-wide commissioning and test or when the network runs stably), however, the current state of the network is expected to be maintained, and the self-optimization of the network is not expected to be enabled. Even in some special cases (for example, commissioning of some functions of the network), only some of the self-optimization functions of the network are expected to be disabled without affecting running of other self-optimization processes. Therefore, to satisfy these actual scenario requirements, the LTE needs to be able to not only provide self-optimization of the network but also control enabling and disabling of each optimization function.

[0004] A 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) network management system introduces a concept of an integration reference point (IRP). An information model of an interface defined by the IRP includes a managed object, a network resource model (NRM), and information exchange semantics. The managed object of the NRM refers to all physical networks and logical networks owned by an operator and nodes (for example, physical devices in an equipment room) connected to those networks. A standard Interface-N is available between an integration reference point manager (IRPManager) and an integration reference point agent (IRPAgent).

[0005] Currently, the 3GPP already defines the following IRPs: an Alarm (alarm) IRP, a Basic CM (basic configuration management) IRP, a Bulk CM (bulk data configuration management) IRP, a Performance Management (performance management) IRP, a Generic Network Resource (generic network resource) IRP, a Notification (notification) IRP, and an Inventory (inventory) IRP. These IRPs already satisfy most interface requirements and service requirements.

[0006] However, in the self-optimization management of the SON, the existing IRPs cannot satisfy the requirements for controlling the enabling and disabling of a self-optimization process, and a state of the self-optimization process cannot be known at any time.

SUMMARY OF THE INVENTION



[0007] Embodiments of the present invention provide a method, an apparatus, and a system for controlling a self-optimization switch to control enabling and disabling of a self-optimization process and know a state of the self-optimization switch.

[0020] Currently, self-optimization fields of the 3GPP include Handover (handover), Load Balancing (load balancing), Interference Control (interference control), Capacity & Coverage (capacity and coverage), RACH Optimization (random access channel optimization), and Energy Saving (energy saving).

[0021] To control a self-optimization switch in these self-optimization fields, embodiments of the present invention configure a self-optimization switch attribute in each field. The mapping relationship is shown in Table 1.
Table 1
Type of the Self-Optimization SwitchValue of the Self-Optimization Switch Attribute
Handover (HO) self-optimization True/False (True/False)
Load Balancing (LB) self-optimization True/False
Inter-Cell Interference Coordination (ICIC) self-optimization True/False
Capacity and Coverage (CC) self-optimization True/False
RACH self-optimization True/False
Energy Saving (ES) self-optimization True/False


[0022] A value of the self-optimization switch attribute in each field may be a Boolean parameter. When the value of the self-optimization switch attribute is True, the self-optimization switch is turned on in this field; otherwise the self-optimization switch is turned off in this field.

[0023] In the embodiments of the present invention, these parameters are used to control the self-optimization switch so as to control enabling and disabling of self-optimization.

[0024] In the embodiments of the present invention, a managed unit may be an Element Management System (EMS) or a network device that includes an integration reference point agent; the managed unit may also be a network device managed by a network management system through an EMS. A managing unit may be an network management system that includes an integration reference point manager.

[0025] The following describes the method, apparatus, and system for controlling a self-optimization switch in detail with reference to the accompanying drawings.

Embodiment 1



[0026] This embodiment of the present invention provides a method for controlling a self-optimization switch. As shown in FIG. 1, the method includes:
101. Obtain a target state of the self-optimization switch, for example, by receiving an instruction that is input by a user and indicates the target state of the self-optimization switch.

[0027] The instruction input by the user indicates a user-expected state of the self-optimization switch. For example, if the user expects that self-optimization of a network can be disabled, the target state of the self-optimization switch in the instruction is off.

[0028] 102. Send a setting command that includes the target state to a managed unit, where the setting command instructs the managed unit to change a state of the self-optimization switch to the target state.

[0029] After the setting command that includes the target state of the self-optimization switch is sent to the managed unit, a setting result returned from the managed unit is received.

[0030] This embodiment of the present invention provides a method for controlling a self-optimization switch. As shown in FIG. 2, the method includes:

201. Receive a setting command that is sent by a managing unit and includes a target state of the self-optimization switch.

202. Change a state of the self-optimization switch to the target state according to the setting command.



[0031] If the target state of the self-optimization switch is off, the self-optimization switch is turned off; if the target state of the self-optimization switch is on, the self-optimization switch is turned on. After the state of the self-optimization switch is changed to the target state, a setting result is returned to the managing unit. If the state of the self-optimization switch is successfully changed to the target state, True is returned to the managing unit; if the state of the self-optimization switch fails to be changed to the target state, False is returned to the managing unit.

[0032] This embodiment of the present invention provides a method for controlling a self-optimization switch. In this embodiment of the present invention, a user-desired target state of the self-optimization switch is known firstly, and then the state of the self-optimization switch is changed so that the state of the self-optimization switch is the same as the target state. By using the technical solution provided in this embodiment of the present invention, the state of the self-optimization switch can be controlled and thereby enabling or disabling of the self-optimization is controlled, which satisfies a self-optimization management requirement.

Embodiment 2



[0033] This embodiment of the present invention provides a method for controlling a self-optimization switch. As shown in FIG. 3, the method includes:

301. Send a query command to a managed unit, where the query command is an instruction for obtaining a current state of the self-optimization switch.

302. Receive the current state of the self-optimization switch returned from the managed unit.



[0034] This embodiment of the present invention provides a method for controlling a self-optimization switch. As shown in FIG. 4, the method includes:

401. Receive a query command sent by a managing unit.

402. Obtain a current state of the self-optimization switch according to the query command.

403. Return the current state of the self-optimization switch to the managing unit.



[0035] This embodiment of the present invention provides a method for controlling a self-optimization switch. In this embodiment of the present invention, the current state of the self-optimization switch is obtained through a query command. By using the technical solution provided in this embodiment of the present invention, the current state of the self-optimization switch can be known at any time, which satisfies a self-optimization management requirement.

Embodiment 3



[0036] Before a managing unit sends a setting command to a managed unit, the managing unit may also query the managed unit for a state of a self-optimization switch; if a state of the self-optimization switch is the same as a user-desired state, the managing unit may not send the setting command to the managed unit.

[0037] This embodiment of the present invention provides a method for controlling a self-optimization switch. The method includes:
  1. 1. Obtain a target state of the self-optimization switch, for example, by receiving an instruction that is input by a user and indicates the target state of the self-optimization switch.
    The instruction input by the user indicates a user-expected state of the self-optimization switch. For example, if the user expects that self-optimization of a network can be disabled, the target state of the self-optimization switch in the instruction is off.
  2. 2. Obtain a current state of the self-optimization switch.
    In this embodiment, the method for obtaining the current state of the self-optimization switch may include but is not limited to: sending a query command to a managed unit, where the query command is an instruction for obtaining the current state of the self-optimization switch; and receiving the current state of the self-optimization switch returned from the managed unit.
  3. 3. If the current state is different from the user-desired state, send a setting command that includes the target state to the managed unit, where the setting command instructs the managed unit to change the state of the self-optimization switch to the target state.


[0038] If the target state of the self-optimization switch is off and the current state of the self-optimization switch is on, a setting command that includes information indicating that the target state of the self-optimization switch is off is sent to the managed unit, where the setting command instructs the managed unit to turn off the self-optimization switch. If the target state of the self-optimization switch is on and the current state of the self-optimization switch is off, a setting command that includes information indicating that the target state of the self-optimization switch is on is sent to the managed unit, where the setting command instructs the managed unit to turn on the self-optimization switch.

[0039] If the current state of the self-optimization switch is the same as the target state, a setting command that includes the target state of the self-optimization switch does not need to be sent to the managed unit.

[0040] After the setting command that includes the target state of the self-optimization switch is sent to the managed unit, a setting result returned from the managed unit is received.

[0041] This embodiment of the present invention provides a method for controlling a self-optimization switch. The method includes:
  1. 1. Receive a setting command that is sent by a managing unit and includes a target state of the self-optimization switch.
    Before the setting command is received, a query command sent by the managing unit is also received, and a current state of the self-optimization switch is obtained according to the query command. Then, the current state of the self-optimization switch is retuned to the managing unit.
  2. 2. Change the state of the self-optimization switch to the target state according to the setting command.


[0042] If the target state of the self-optimization switch is off, the self-optimization switch is turned off; if the target state of the self-optimization switch is on, the self-optimization switch is turned on. After the state of the self-optimization switch is changed to the target state, a setting result is returned to the managing unit. If the state of the self-optimization switch is successfully changed to the target state, True is returned to the managing unit; if the state of the self-optimization switch fails to be changed to the target state, False is returned to the managing unit.

[0043] This embodiment of the present invention provides a method, an apparatus, and a system for controlling a self-optimization switch. In this embodiment of the present invention, the current state of the self-optimization switch is obtained firstly, and then the current state of the self-optimization switch is compared with the target state input by the user; if the current state of the self-optimization switch fails to meet the user's requirement, the state of the self-optimization switch is changed so that the state of the self-optimization switch is the same as the target state. By using the technical solution provided in this embodiment of the present invention, the state of the self-optimization switch can be known and controlled, and thereby enabling or disabling of the self-optimization is controlled, which satisfies a self-optimization management requirement.

Embodiment 4



[0044] In this embodiment of the present invention, a self-optimization IRP is added in a 3GPP Interface-N, and a related operation on the IRP is defined to control a self-optimization switch.

[0045] This embodiment of the present invention provides a method for controlling a self-optimization switch. As shown in FIG. 5, the method includes:
501. An integration reference point manager sends a query command to an integration reference point agent.

[0046] A user sends a query command to the IRP Agent through the IRP Manager, where the query command is an instruction for obtaining a state of a self-optimization switch supported by a corresponding managed unit. For example, in a specific implementation process, a format of the query command may be: listSoFuncSwitch(ctrlObjInfomation,optimizationTypeList).

[0047] The input parameter ctrlObjInfomation represents a managed unit providing a self-optimization capability, and a value type may be a string or an enumeration type. A possible value is EM (Element Management System), NE instance (one or multiple network element instances), and NE TYPE (network element type). The optimizationTypeList is a list of optimization switch types that are owned by the managed unit. A type of each element in the list is optimizationType and indicates an optimization switch type owned by the managed unit.

[0048] Specifically, the optimizationType may be an enumeration type. For example, LB, ICIC, HO, RACH, CC, and ES may be used to represent load balancing self-optimization, inter-cell interference coordination self-optimization, handover self-optimization, RACH self-optimization, capacity and coverage self-optimization, and energy saving self-optimization respectively.

[0049] 502. The integration reference point agent returns a current state of the self-optimization switch to the integration reference point manager.

[0050] After receiving a query command sent by the integration reference point manager, the integration reference point agent queries a switch state in a self-optimization field supported by the corresponding managed unit, and returns the queried current state of the self-optimization switch through a list of current state information of the self-optimization switch owned by the managed unit. For example, return the queried current state of the self-optimization switch to the integration reference point manager by outputting a selfOptFuncSwitchList parameter. The selfOptFuncSwitchList is the list of current state information of the self-optimization switch owned by the managed unit. Each element in the list is the managed unit, the self-optimization switch owned by the managed unit, and a corresponding list of current state values, for example, (ctrlObjInfomation,List<optimizationType,switch>). If the returned current state value of the switch is on (For description in an intuitive manner, on is used to replace True and off is used to replace False; the state value may also be directly represented by True and False. For example, True may be used to indicate that the switch is turned on, and False may be used to indicate that the switch is turned off. Certainly, True may also be used to indicate that the switch is turned off, and False may also be used to indicate that the switch is turned on), the state of the switch is on; if the returned current state value of the switch is off, the state of the switch is off.

[0051] The following describes several query cases by using some examples:
  1. 1. If the integration reference point manager wants to query a state of an ICIC self-optimization switch on the EM, the format of the query command is listSoFuncSwitch(EM,ICIC). If the returned query result is "EM,(ICIC,on)", the current state of the ICIC self-optimization switch on the EM is on.
  2. 2. If the integration reference point manager wants to query states of an LB self-optimization switch and the ICIC self-optimization switch on an entity network element eNodeB_A, the format of the query command is: listSoFuncSwitch(eNodeB_A,(LB,ICIC)). If the returned query result is "eNodeB_A,(LB, on;ICIC,off)", the current state of the LB self-optimization switch on the eNodeB_A is on and the current state of the ICIC self-optimization switch on the eNodeB_A is off.
  3. 3. If the integration reference point manager wants to query the states of the LB self-optimization switch and the ICIC self-optimization switch on more than two entity network elements, for example, eNodeB_A and eNodeB_B, the format of the query command is: listSoFuncSwitch((eNodeB_A,eNodeB_B),(LB,ICIC)). If the returned query result is "eNodeB_A, (LB,on,IC,off); eNodeB B, (LB,on,ICIC,on)", the state of the LB self-optimization switch on the eNodeB_A is on, the state of the ICIC self-optimization switch on the eNodeB_A is off, and the states of both the LB self-optimization switch and the ICIC self-optimization switch on the eNodeB_B are on.
  4. 4. If the integration reference point manager wants to query the states of the LB self-optimization switch and the ICIC self-optimization switch on a type of network element (for example, an eNodeB type), the format of the query command is: listSoFuncSwitch(ENBFunction,(LB,ICIC)), and the returned result includes the states of the LB self-optimization switch and the ICIC self-optimization switch on all network elements of the eNodeB type. If the returned query result is "eNodeB_A, (LB,on;ICIC,off); eNodeB_B, (LB,on;ICIC,off)", the state of the LB self-optimization switch on the eNodeB_A is on, the state of the ICIC self-optimization switch on the eNodeB_A is off, the state of the LB self-optimization switch on the eNodeB_B is on, and the state of the ICIC self-optimization switch on the eNodeB_B is off.


[0052] 503. The integration reference point manager sends a setting command to the integration reference point agent, instructing the managed unit to change the state of the self-optimization switch to the target state.

[0053] For example, in a specific implementation process, a format of the setting command sent by the integration reference point manager is: setSoFuncSwitch(ctrlObjInfomation,optimizationTypeSwitchList), where, the ctrlObjInfomation represents the managed unit providing the self-optimization capability, the optimizationTypeSwitchList is a specific list of switch parameters, for example, List of <optimizationType,switch>. For details about the parameters, see the description about the query command listSoFuncSwitch.

[0054] The following describes several setting cases by using some examples:
  1. 1. To set the state of the ICIC self-optimization switch on the EM to on, the integration reference point manager sends a setting command setSoFuncSwitch(EM,ICIC,off) to the IRP Agent.
  2. 2. To set the states of both the ICIC self-optimization switch and a CC self-optimization switch on the network element entity eNodeB_A to on, the integration reference point manager sends a setting command setSoFuncSwitch(eNodeB_A,(ICIC,on),(CC,on)) to the IRP Agent.
  3. 3. To set the states of both the LB self-optimization switch and the CC self-optimization switch on the network element entities eNodeB_A and eNodeB_B to off, the integration reference point manager sends a setting command setSoFuncSwitch((eNodeB_A,eNodeB_B),(LB,off),(CC,off)) to the IRP Agent.
  4. 4. To set the states of both an RACH self-optimization switch and an HO self-optimization switch on all the network elements of the ENBFunction type to on, the integration reference point manager sends a setting command setSoFuncSwitch(ENBFunction,(RACH,on),(HO,on)) to the IRP Agent.


[0055] 504. The integration reference point agent returns a setting result to the integration reference point manager.

[0056] After receiving the setting command sent by the integration reference point manager, the integration reference point agent also needs to return the setting result to the integration reference point manager.

[0057] If the integration reference point agent successfully sets the state of the self-optimization switch to the target state, the integration reference point agent returns True to the integration reference point manager; if the integration reference point agent fails to set the state of the self-optimization switch to the target state, the integration reference point agent returns False to the integration reference point manager.

[0058] This embodiment of the present invention provides a method for controlling a self-optimization switch. By using the technical solution provided in this embodiment of the present invention, the state of the self-optimization switch can be known at any time and the state of the self-optimization switch can be controlled. Thereby, enabling or disabling of the self-optimization is controlled, which satisfies a self-optimization management requirement.

Embodiment 5



[0059] This embodiment of the present invention provides a method for controlling a self-optimization switch.

[0060] In this embodiment, the self-optimization switch is controlled by changing an NRM on an existing NRM IRP. In this embodiment of the present invention, a corresponding switch attribute is defined for each self-optimization field. A value of the switch is Boolean. When the switch attribute is True, the self-optimization switch is turned on; otherwise, the self-optimization switch is turned off.

[0061] Because entities that provide a self-optimization capability may be centralized on an EM, or distributed on each NE, or even concurrently distributed on the EM and an NE, a switch control attribute needs to be added to NRMs on an IRPAgent, the EM, and the NE respectively.

[0062] Table 2 is a list of IRPAgent attributes after the switch control attribute is added.

[0063] In Table 2, attributes iRPAgentId and systemDN are existing attributes of an existing IRPAgent NRM, and attributes selfOptHOFuncEnabled, selfOptLBFuncEnabled, selfOptICFuncEnabled, selfOptCCFuncEnabled, selfOptRACHFuncEnabled, and selfOptESFuncEnabled are newly added attributes. M means mandatory, CM means mandatory under some conditions, and C means conditional. Taking the selfOptRACHFuncEnabled attribute as an example, the corresponding support limitation is CM, the corresponding read limitation is M, and the corresponding write limitation is M, indicating that the on/off state of the selfOptRACHFuncEnabled attribute may be queried and obtained when self-optimization is supported and that the on/off state of the selfOptRACHFuncEnabled attribute may also be set.

[0066] When the integration reference point agent is distributed on each NE, the switch control attribute needs to be added to the NRMs of each NE. For example, when the integration reference point agent is distributed on a network element which is an eNodeB type, the switch control attribute needs to be added to the NRM of the eNodeB.
