Description

Multi-self-organizing network management method and device

Technical Field

The present invention relates to the field of telecommunications management, and in particular, to a method and an apparatus for managing multiple ad hoc networks in a mobile communication network.

Background

In a mobile communication network, as the network architecture is flattened, the number of base stations is increasingly huge, and more data need to be processed by the base stations, so that the complexity and management cost of network management are increased to a level that cannot be tolerated by network operators. For this reason, self-organizing network (SON) functionality was first introduced and studied in LTE networks and later gradually expanded to home base station networks, UMTS/CDMA and even 2G networks where SON concepts were also introduced.

SON functions are specifically divided into self-configuration, self-optimization, and self-healing functions. The self-configuration comprises that after the base station is powered on, the software version, the wireless configuration data and the transmission configuration data are automatically downloaded, and finally, the normal work is carried out, namely the plug and play is often said. The self-optimization comprises automatic optimization of a neighbor list, automatic switching optimization, automatic load balancing, automatic capacity and coverage optimization, automatic interference optimization and the like. The self-healing mainly means that the base station can automatically repair errors or switch to standby hardware after the software and hardware faults occur. At present, the SON function management is divided into three types, namely NMS centralized type, EMS centralized type and distributed type, and the corresponding network management architecture comprises a network element layer, an Element Management Layer (EML) and a Network Management Layer (NML) from bottom to top. The method specifically comprises the following steps:

NMS centralized: and the SON decision point is at the network management layer, and the NMS collects other related system information or lower-layer related information and then carries out SON decision to trigger the network element layer to execute a related command.

EMS centralized type: and the SON decision point is arranged on a network element management layer, and the EMS collects the information reported by the network element to carry out SON decision. In this way, the SON policy can be customized in advance by the operator, but the decision point whether to start the SON function should be in the EMS.

Distributed: and the SON decision point is at the network element, and the network element carries out SON decision according to the information collected by the network element. Also in this way, the SON policy can be customized in advance by the operator, but the decision point whether to start the SON function should be at the network element.

A conventional multi-network SON management architecture is shown in fig. 1. Because the centralized real-time performance of the NMS is poor, most of the current centralized decisions of the SON are in the EMS, but the SON coordination among different EMSs is still in the NMS, because currently, there is no effective interface among different EMSs, and the information of the external system required by the SON decisions can be shared. However, coordination by the NMS still does not solve the real-time problem and is therefore not practically feasible. This coordination between different EMSs is particularly problematic in multi-network scenarios. For example, when performing handover optimization in an edge area of two networks (i.e., networks managed by two EMS a and EMS B, respectively), the EMS a in the existing mechanism modifies the wireless parameters of the base station or cell in the management domain and does not actively notify the other EMS B. Therefore, although the external cell of EMS B retains the handover-related parameters of the corresponding EMS a cell, its accuracy cannot be guaranteed, and thus the EMS cannot make a self-optimization decision according to the retained external cell parameters. In addition, the X2 interface of the base station between two networks cannot be automatically established, specifically, after a base station is added in the EMS a management domain, it needs to establish an X2 interface with an adjacent external base station, but cannot obtain the configuration information of the external base station needed to establish the X2 interface. In summary, SON information cannot be shared between different EMSs under multiple networks.

Detailed Description

In order to solve the problem that different EMSs in multiple networks cannot share SON information, embodiments of the present invention provide a method and an apparatus for managing multiple self-organizing networks, which implement an SON coordination mechanism between different EMSs by sharing specific related base station and cell configuration information and alarm information between EMSs, and ensure correct operation of SON functions.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

First, a first embodiment of the present invention will be described with reference to the drawings.

The embodiment of the invention provides a multi-self-organizing network management method, EMS can acquire the configuration information of a specific base station or cell to external EMS, thereby ensuring the correct operation of SON function in the EMS.

The process of using the method to complete the cell or base station configuration information acquisition between different EMSs is shown in fig. 2, and includes:

step 201, the EMS maintains a cell mapping table and/or a base station mapping table;

in this step, in a network environment with multiple SONs, each EMS configures a cell mapping table of the cell in the EMS and an external associated cell and a base station mapping table of the base station in the SON and an external associated base station. The cell mapping table records the association relationship between a cell in the EMS and an EMS external cell set as a cell adjacent to the cell, and the base station mapping table records the association relationship between a base station in the EMS and an EMS external base station connected to the base station through an X2 interface.

Specifically, the cell mapping relationship table and the base station mapping relationship table are maintained to include the following contents:

1. when the EMS deletes the relation of the adjacent cell according to the request of the ANR function, if the adjacent cell is an external cell, judging whether the cell exists in the cell mapping relation table according to the global unique identifier of the adjacent cell;

2. When the EMS deletes an X2 interface object according to the request of the ANR function, if the X2 interface remote base station is an external base station, judging whether the remote base station exists in the base station mapping relation table according to the global unique identification of the remote base station;

3. When the EMS receives a cell or base station object deletion notification sent by other EMS, judging whether the cell exists in the cell mapping relation table or whether the base station exists in the base station mapping relation table according to the global unique identifier of the cell or the base station;

Step 202, the EMS judges to send a request for acquiring configuration information of a specified cell or base station to the target EMS according to a preset judgment mechanism by combining the cell mapping relation table and/or the base station mapping relation table, wherein the request at least carries a global unique identifier of the cell or the base station;

the decision mechanism related to the embodiment of the invention is specifically as follows:

1. when an EMS adds an adjacent cell relation to a cell managed by the EMS according to a request of an Automatic Neighbor Relation (ANR) function, if the adjacent cell is an external cell, judging whether the adjacent cell exists in a cell mapping relation table of a SON corresponding to the EMS according to a global unique identifier of the adjacent cell;

and when the adjacent cell does not exist in the cell mapping relation table, adding the association relation between the adjacent cell and the cell in the SON corresponding to the EMS to the cell mapping relation table, taking one or more EMS except the EMS as a target EMS, and requesting the target EMS to acquire the configuration information of the adjacent cell.

2. When an EMS adds an X2 relationship between a base station in an SON corresponding to the EMS and a remote base station according to the request of an ANR function, if the remote base station is an external base station, judging whether the remote base station exists in a base station mapping relationship table of the SON corresponding to the EMS according to the global unique identification of the remote base station;

and when the remote base station does not exist in the base station mapping relation table, adding the association relation between the remote base station and the base station in the SON corresponding to the EMS to the base station mapping relation table, taking one or more EMS except the EMS as a target EMS, and requesting the target EMS to acquire the configuration information of the remote base station.

Step 203, the EMS receives and stores the configuration information of the cell or the base station returned by the target EMS.

Receiving the EMS request for acquiring the cell or base station configuration information, the EMS needs to determine whether to respond to the request, and respond to corresponding content, which is specifically shown in fig. 3 and includes:

step 301, receiving a request for acquiring cell or base station configuration information sent by other EMS by the EMS, and judging whether the cell or the base station is a cell or a base station in the EMS;

in this step, if the EMS receives a request for acquiring cell or base station configuration information sent by another EMS, the EMS first extracts the globally unique identifier of the cell or base station carried in the request, and determines whether the cell or base station is a cell or base station in the EMS according to the identifier.

Step 302, if the cell or the base station is the cell or the base station in the EMS, returning configuration information of the cell or the base station;

in this embodiment of the present invention, the configuration information includes a specific attribute and/or all attribute values of the cell or the base station.

The second embodiment of the present invention will be described below with reference to the drawings.

An embodiment of the present invention provides a method for managing multiple self-organizing networks, where a process of sending and receiving notification messages between different EMSs in a multiple SON network environment is completed by using the method, as shown in fig. 4, where the process includes:

step 401, the EMS maintains a cell mapping table and/or a base station mapping table;

in this step, in a network environment with multiple SON, each EMS configures a cell mapping relationship table between the EMS internal cell and the external associated cell and a base station mapping relationship table between the EMS internal base station and the external associated base station. The cell mapping table records the association relationship between a cell in the EMS and an EMS external cell set as a cell adjacent to the cell, and the base station mapping table records the association relationship between a base station in the EMS and an EMS external base station connected to the base station through an X2 interface.

deleting the association relationship between the neighbor cell and the cell in the EMS from the cell relationship list when the cell exists in the cell mapping relationship table.

Step 402, the EMS determines to send a notification of attribute change or alarm or state change or object deletion of a cell or a base station to a target EMS according to a preset decision mechanism in combination with the cell mapping relationship table and/or the base station mapping relationship table, where the notification carries at least a globally unique identifier of the cell or the base station;

1. when the configuration information of a cell or a base station object managed by the EMS is changed, the EMS judges whether the cell exists in the cell mapping relation table or whether the base station exists in the base station mapping relation table according to the identification of the cell or the base station object or the globally unique identification of the cell or the base station;

2. When receiving an alarm or state change notification sent by a network element, the EMS determines whether the cell exists in the cell mapping relationship table or whether the base station exists in the base station mapping relationship table according to the identifier of the cell or base station object in the alarm or state change notification;

3. When the EMS deletes a cell or base station object managed by the EMS, the EMS takes one or more EMS except the EMS as target EMS, and sends an object deletion notice of the cell or base station object to the target EMS.

The EMS that receives the notification needs to perform corresponding operations on the local information according to the notification, which is specifically shown in fig. 5 and includes:

step 501, an EMS receives a notification of attribute change or alarm or state change or object deletion of a cell or a base station, wherein the notification at least carries a global unique identifier of the cell or the base station;

step 502, the EMS judges whether the cell or the base station is an external cell or a base station managed by the EMS;

in this step, the EMS extracts the globally unique identifier of the cell or base station carried in the notification, and queries a local cell mapping relationship table or base station mapping relationship table according to the globally unique identifier to determine whether the cell or base station is an external cell or base station managed by the EMS.

Step 503, when the cell and the base station are external cells or base stations managed by the EMS, updating the related information of the locally stored cell or base station according to the notification;

according to different received notification contents, the updating operation in this step is also different, specifically as follows:

1. storing and updating the attribute of the cell or the base station;

2. saving and updating the alarm and/or state of the cell or the base station;

3. updating attributes of the cell or base station managed by the EMS and related to the cell or base station.

Moreover, the P2P interface cannot solve the problem of automatic establishment of the X2 interface in the present invention.

The embodiment of the invention provides a method and a device for managing a multi-self-organizing network, wherein each SON EMS maintains a cell mapping relation table of a SON inner cell and an outer associated cell and a base station mapping relation table of a SON inner base station and an outer associated base station, the EMS judges to send a request for acquiring configuration information of a specified cell or base station to a target EMS according to a preset judgment mechanism by combining the cell mapping relation table and/or the base station mapping relation table of the SON corresponding to the EMS, the request at least carries a global unique identifier of the cell or the base station, or the EMS judges to send a notice of attribute change or alarm or state change or object deletion of the cell or the base station to the target EMS according to the preset judgment mechanism by combining the cell mapping relation table and/or the base station mapping relation table of the SON corresponding to the EMS, the notice at least carries the global unique identifier of the cell or the base station, the intercommunication of SON information among EMS of different SONs on an application layer is realized, and the problem that the SON information can not be shared among different EMS of multiple networks is solved. Compared with the prior art, the technical scheme provided by the embodiment of the invention allows configuration and alarm information of an external cell or a base station to be instantly notified and shared among different EMS due to the fact that the SON coordination mechanism and device among different EMS are additionally arranged, and solves the problem that the prior art cannot support SON coordination among different EMS. The method and the system can be used not only between two or more EMS for managing the self-organizing network, but also between EMS for only supporting partial base station self-organizing network functions.
