Detailed Description

In order to solve the problem that communication connection between all base stations in a whole base station cluster and base stations of other base station clusters is affected due to the fact that a cluster head base station fails in the prior art, the embodiment of the invention adds a standby cluster head base station in each base station cluster. The standby cluster head base station is completely the same as the original cluster head base station in the base station cluster, has the same direct connection function as other base stations, and also has the functions of monitoring and maintaining the connection state of each base station in the cluster and among the base stations, and maintaining the interconnection and routing between the cluster head base stations of other base station clusters. When the cluster head base station works normally, the standby cluster head base station is only used as a common in-cluster base station and only needs to implement a direct connection function. When the cluster head base station fails, the standby cluster head base station performs cluster head configuration to replace the failed cluster head base station, so that the coverage area affected by the failure of the cluster head base station is reduced, and the self-healing capability and the communication stability of the network are improved. In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 2, the present invention provides a schematic flow chart of a first embodiment of a self-repairing method for a base station cluster. As shown in the figure, the self-repairing method for a base station cluster in this embodiment includes:

step 101, monitoring a cluster head base station, and acquiring a working state of the cluster head base station.

The direct control device monitors each cluster head base station controlled by the direct control device, and acquires the working state of each cluster head base station. Specifically, the express management and control device receives cluster head information sent by a cluster head base station according to a predetermined time or a predetermined period; if the cluster head information sent by the cluster head base station is not received within the preset judging time, the working state of the cluster head base station is a fault state; if the cluster head information sent by the cluster head base station is received within the preset judging time, if the fault information reported by the cluster head base station is received, the working state of the cluster head base station is a fault state, otherwise, the working state of the cluster head base station is a normal state. Here, it should be noted that: in essence, the cluster head base station sends the cluster head information to the direct connection management and control device according to a predetermined time or a predetermined period in order to ensure the communication connection with the direct connection management and control device. If the failure reason of the cluster head base station is that the failure reason cannot communicate with the direct connection control device and the cluster head base stations of other base station clusters in the network, the direct connection control device cannot receive the cluster head information sent by the cluster head base station within the preset judgment time, and therefore the direct connection control device can directly determine that the cluster head base station fails. If the reason for the failure of the cluster head base station is only the failure serving as the management and control capability of the cluster head, such as loss of an intra-cluster routing list and/or an inter-cluster routing list, communication loss or overload, the cluster head base station may send cluster head information to a direct connection management and control device according to a predetermined time or a predetermined period, the direct connection management and control device may receive the cluster head information sent by the cluster head base station within a preset determination time, only when the direct connection management and control device receives the failure information reported by the cluster head base station, the direct connection management and control device may determine that the cluster head base station fails, otherwise, the direct connection management and control device determines that the cluster head base station normally operates. The failure information carries cluster head base station failure reason information, so that the direct connection management and control device can acquire the failure reason of the cluster head base station according to the failure reason information, and a basis is provided for repairing a follow-up cluster head base station.

Step 102, if the working state of the cluster head base station is a failure state, acquiring identification information of a standby cluster head base station, wherein the standby cluster head base station and the cluster head base station are the same base station cluster.

Because only the cluster head base station and the direct connection control device establish direct connection bearing in the base station cluster, the standby cluster head base station in the base station cluster is the same as other base stations and only serves as a common base station with the direct connection function. Therefore, when the working state of the cluster head base station is a failure state, the express management and control needs to first acquire the identification information of the standby cluster head base station to create an express bearer with the standby cluster head base station. Specifically, when monitoring that the cluster head base station fails, the cut-through management and control device acquires identification information of the cluster head base station according to identification information of the cluster head base station carried by the failure information if the cut-through management and control device determines that the cluster head base station fails according to the received failure information reported by the cluster head base station. If the direct connection control device determines that the cluster head base station fails through not receiving the cluster head information sent by the cluster head base station within a preset judgment time, the direct connection control device queries the identification information of the cluster head base station corresponding to the preset judgment time to acquire the identification information of the cluster head base station. The identification information includes cluster group identification information and intra-cluster address information. The cut-through management and control device searches for in-cluster address information of a standby cluster head base station having the cluster group identification information according to a base station cluster information list, wherein the cluster group identification information and the searched in-cluster address information form identification information of the standby cluster head base station. The base station cluster information list comprises cluster group identification information and intra-cluster address information of each base station cluster head base station, and cluster group identification information and intra-cluster address information of each base station cluster standby cluster head base station.

103, sending a bearer creation request to the standby cluster head base station according to the identification information of the standby cluster head base station, so that the standby cluster head base station returns corresponding creation response information;

specifically, the express delivery control device sends a Bearer creation request, such as Bearer Setup request, to the standby cluster head base station according to the cluster group identification information and the intra-cluster address information of the standby cluster head base station, so as to request to create the express delivery Bearer with the standby cluster head base station, and after receiving creation Response information returned by the standby cluster head base station, the express delivery control device completes creation of the express delivery Bearer between the express delivery control device and the standby cluster head base station, such as Bearer Setup Response. After the creation of the direct bearer between the direct control device and the standby cluster head base station is completed, the direct control device can communicate with the standby cluster head base station.

And 104, sending cluster head replacement information to the standby cluster head base station according to the received establishment response information so as to enable the standby cluster head base station to execute cluster head configuration.

Specifically, after receiving the creation response information returned by the standby cluster head base station, the express management and control device may send cluster head replacement information to the standby cluster head base station through the created express bearer, so that the standby cluster head base station executes cluster head configuration.

In the embodiment, when the cluster head base station fails, the failed cluster head base station is switched to the standby cluster head base station, so that the standby cluster head base station replaces the failed cluster head base station to work, the normal communication of the base station cluster is ensured, the problem that the direct communication between all base stations in the whole base station cluster and other base station cluster base stations is influenced due to the failure of the cluster head base station in the prior art is solved, and the self-healing capability and the communication stability of the network are improved.

Further, if the cause of the failure of the cluster head base station is a failure serving as the management and control capability of the cluster head, such as loss of the intra-cluster routing list and/or the inter-cluster routing list, communication loss or overload, the cluster head base station indicates that the cluster head base station may communicate with the direct connection management and control device. Based on the principle that only one cluster head base station can exist in one base station cluster, the direct connection management and control device needs to release direct connection bearing with a failed cluster head base station. Therefore, the method for self-repairing a base station cluster according to the foregoing embodiment, as shown in fig. 3, should further include:

and 105, sending a bearer release request to the cluster head base station.

Specifically, the express management and control device sends a bearer release Request, such as a bearerelease Request, to the cluster head base station to Request release of the established communication link with the cluster head base station.

And step 106, receiving release response information returned by the cluster head base station according to the bearer release request, and releasing the established direct bearer with the cluster head base station.

Specifically, the cut-through management and control device receives Release Response information, such as Bearer Release Response, returned by the cluster head base station according to the Bearer Release request. And the cut-through management and control device releases the cut-through bearer established between the cut-through management and control device and the cluster head base station after receiving the release response.

Here, it should be noted that: in the above embodiment, the cluster head base station in the failure state needs to release the direct bearer with the direct bearer control device, and also needs to release the created direct bearer with the cluster group base stations of other base station clusters in the network. Specifically, the cluster head base station sends a bearer release request to the cluster head base stations of other base station clusters. And the cluster head base stations of other base station clusters return corresponding release response information to the failed cluster head base station according to the received load release request so as to respectively release the through load between the failed cluster head base station and the cluster head base stations of other base station clusters. In addition, if the failure reason of the cluster head base station in the failure state is that the cluster head base station cannot communicate with the express traffic control device and the cluster head base stations of other base station clusters in the network, the express traffic control device does not need to perform the release of the express bearer by using the above steps 105 and 106.

Further, in the self-repairing method for a base station cluster described in the foregoing embodiment, after the step 103, the method further includes: and receiving the configured cluster head state information reported by the standby cluster head base station. Specifically, in order to maintain the capability of connection and routing between cluster heads, manage and control the cluster head base stations of each base station cluster, and monitor the operating state of each cluster head base station, the express management and control device needs to store the state information of the cluster head base stations of each base station cluster, where the state information may include: the cluster head base station comprises load capacity information of the cluster head base station, management and control capacity information of the cluster head base station (namely capacity information for establishing, releasing and updating direct connection in a cluster and among clusters), and attribute information of the cluster head base station, such as preset time or preset period, for sending the cluster head information. Therefore, with the above steps, the direct connection management and control device acquires the attribute information for managing, controlling and monitoring the standby cluster head according to the received configured cluster head state information reported by the standby cluster head base station.

Further, the self-repairing method for a base station cluster according to the foregoing embodiment further includes: the direct connection management and control device generates cluster head updating information carrying the standby cluster head base station identification information according to the received state information; and sending cluster head updating information carrying the identification information of the standby cluster head base station to each cluster head base station in the base station cluster information list according to the base station cluster information list, so that each cluster head base station updates the corresponding cluster head identification information in the routing list among the clusters according to the cluster head updating information. Specifically, the direct connection management and control device generates cluster head update information carrying the identification information of the standby cluster head base station according to the post-cluster-configuration state information received from the standby cluster head base station. And the direct connection control device sends the cluster head updating information to each cluster head base station in the base station cluster information list according to a pre-stored base station cluster information list. Wherein the base station cluster information list includes: the base station cluster information list comprises identification information of cluster head base stations of all base station clusters and identification information of standby cluster head base stations of all base station clusters. The identification information includes: cluster group identification information and intra-cluster address information.

As shown in fig. 4, a flow diagram of a third embodiment of the self-repair method for a base station cluster provided by the present invention is shown. As shown in fig. 4, the third embodiment of the self-repair method for a base station cluster includes:

step 201, receiving a bearer creation request sent by a direct connection management and control device, where the bearer creation request is that the direct connection management and control device monitors a cluster head base station, acquires identification information of a standby cluster head base station when the working state of the cluster head base station is a failure state, and sends the identification information according to the identification information, where the standby cluster head base station and the cluster head base station are in the same base station cluster.

Specifically, the standby cluster head base station receives a bearer creation Request, such as a beareseetup Request, sent by the cut-through controller. The bearer creation request is sent when the cut-through management and control device monitors that a cluster head base station of a base station cluster where the standby cluster head base station is located fails. When the direct connection management and control device monitors that the cluster head base station fails, if the direct connection management and control device determines that the cluster head base station fails according to the received fault information reported by the cluster head base station, the direct connection management and control device acquires the identification information of the cluster head base station according to the identification information of the cluster head base station carried by the fault information. If the direct connection control device determines that the cluster head base station fails through not receiving the cluster head information sent by the cluster head base station within a preset judgment time, the direct connection control device queries the identification information of the cluster head base station corresponding to the preset judgment time to acquire the identification information of the cluster head base station.

Step 202, according to the bearer creation request, returning corresponding creation response information to the express management and control device.

Specifically, the standby cluster head base station returns corresponding creation response information, that is, Bearer setup response, to the express control device according to the Bearer creation request, for example, Bearer setup request, and after the express control device receives the creation response information returned by the standby cluster head base station, the express control device completes creation of the express Bearer with the standby cluster head base station.

Step 203, receiving cluster head replacement information sent by the express management and control device, where the cluster head replacement information is sent by the express management and control device according to the received creation response information.

Specifically, the standby cluster head base station receives the cluster head replacement information sent by the direct connection management and control device. And the cluster head replacement information is sent to the standby cluster head base station through the created direct bearer after the direct control device receives the creation response information.

And 204, executing cluster head configuration according to the cluster head replacement information.

Specifically, the standby cluster head base station sends first request information to the cluster head base station according to the cluster head replacement information, so that the cluster head base station returns first response information carrying identification information of each cluster head base station in an inter-cluster routing list of the cluster head base station and identification information of each base station in a cluster in an intra-cluster routing list according to the first request information. And if the standby cluster head base station receives the first response information within the preset time, the standby cluster head base station establishes an inter-cluster routing list and an intra-cluster routing list according to the first response information. If the standby cluster head base station does not receive the first response information within the preset time, the standby cluster head base station sends second request information to the direct connection control device, so that the direct connection control device returns second response information carrying identification information of each cluster head base station in the network according to the second request information, and the standby cluster head base station establishes an inter-cluster routing list according to the second response information; and the standby cluster head base station broadcasts third request information, so that the base station receiving the third request information returns third response information carrying base station identification information according to the third request, and the standby cluster head base station establishes an intra-cluster routing list according to the third response information. Then, the standby cluster head base station sends a bearer creation request to each cluster head base station in the inter-cluster routing list according to the established inter-cluster routing list, so that each cluster head base station returns corresponding creation response information to create a direct bearer with each cluster head base station. And the standby cluster head base station sends update information carrying cluster head identification information to each base station in the cluster routing list according to the established cluster routing list, so that each base station updates the cluster head identification information in each routing list according to the cluster head identification information.

Here, it should be noted that: when the cluster head base station fails, the direct connection control device configures a standby cluster head base station of a base station cluster where the cluster head base station is located as the cluster head base station, and the cluster head base station waits for repair. And when the cluster head base station is repaired, the cluster head base station is a standby cluster head base station. Therefore, in the above embodiment, the concepts of the backup cluster head base stations are relative, that is, when one cluster head base station works, the other cluster head base station is the backup cluster head base station, and when the backup cluster head base station is configured as the cluster head base station due to the failure of the cluster head base station, the cluster head base station is the backup cluster head base station after being repaired.

Further, in the base station cluster self-repairing method according to the third embodiment, after the step 204, the method further includes: and reporting the configured state information of the cluster head to the direct connection control device. Specifically, the standby cluster head base station reports the configured state information of the cluster head to the express management and control device, so that the express management and control device acquires the load capacity information of the standby cluster head, the management and control capacity information, and the attribute information of the cluster head information, such as the predetermined time or the predetermined period, according to the state information, and manages, controls and monitors the standby cluster head base station according to the acquired attribute information.

The self-repairing method for the base station cluster provided by the embodiment of the invention is further described with reference to the example shown in fig. 5. As shown in fig. 5, the network in this example includes a first base station cluster, a second base station cluster, and a direct connection management and control device for managing and controlling the two base station clusters and implementing direct connection information between base stations in the two base station clusters. And the first base station cluster and the second base station cluster are respectively provided with a cluster head base station, a standby cluster head base station and three base stations. The cluster head base station and the standby cluster head base station have the same direct connection function as other base stations, and also have the functions of monitoring and maintaining the connection state of each base station and among the base stations in the cluster, and maintaining the interconnection and routing between the cluster head base stations of other base station clusters. When the cluster head base station works normally, the standby cluster head base station is only used as a common in-cluster base station and only needs to implement a direct connection function. When the cluster head base station fails, the standby cluster head base station performs cluster head configuration, namely an intra-cluster routing list and an inter-cluster routing list need to be established so as to monitor and maintain the connection state of each base station in the cluster and among the base stations, and maintain interconnection and routing among the cluster head base stations of other base station clusters. In the figure, the (X, Y) characteristics marked under the cluster head base station, the standby cluster head base station and each base station are the identification information of the base stations. X is characterized by cluster group identification information, and Y is characterized by address information in the cluster. As shown in fig. 6 and 7, the self-repair method for a base station cluster according to this embodiment is implemented as follows:

step 301, reporting a failure message to the direct connection management and control device 3 by the cluster head base station 11 of the first base station cluster.

Here, it should be noted that: in this embodiment, the failure of the cluster head base station 11 is only a failure occurring as the management and control capability of the cluster head, such as loss of the intra-cluster routing list and/or the inter-cluster routing list, communication loss or overload. Therefore, a direct bearer still exists between the cluster head base station 11 and the direct control device.

Step 302, the express management and control device 3 receives a fault message reported by the cluster head base station 11, and acquires identification information (1, 1) of the cluster head base station 11 according to the fault message, where the fault message carries identification information of the cluster head base station, and the identification information includes cluster group identification information and in-cluster address information.

Step 303, the express management and control device 3 searches for the intra-cluster address information (2) of the standby cluster head base station 12 having the cluster group identification information (1) in the base station cluster information list according to the cluster group identification information (1) of the identification information. The cluster group identification information (1) of the cluster head base station 11 and the searched intra-cluster address information (2) constitute identification information (1, 2) of the backup cluster head base station 12.

Step 304, the express management and control device 3 sends a bearer creation request to the standby cluster head base station 12 according to the identification information (1, 2) of the standby cluster head base station 12. And the standby cluster head base station 12 returns corresponding creation response information to the express delivery control device 3 according to the bearer creation request, and establishes express delivery bearer with the express delivery control device 3.

In step 305, after receiving the creation response information returned by the standby cluster head base station 12, the express management and control device 3 sends cluster head replacement information to the standby cluster head base station 12.

Step 306, the standby cluster head base station 12 sends first request information to the cluster head base station 11 according to the cluster head replacement information.

Step 307, as shown in fig. 6, the cluster head base station 11 returns, according to the first request information, first response information carrying identification information of each cluster head base station in the inter-cluster routing list of the cluster head base station 11 and identification information of each base station in a cluster in the intra-cluster routing list; if the standby cluster head base station 12 receives the first response information within a preset time, the standby cluster head base station 12 establishes an inter-cluster routing list and an intra-cluster routing list according to the first response information. If the standby cluster head base station 12 does not receive the first response information within the preset time, that is, it indicates that the cluster head base station 11 loses the inter-cluster routing list and the intra-cluster routing list, as shown in fig. 7, the standby cluster head base station 12 sends second request information to the express management and control device 3, so that the express management and control device 3 returns second response information carrying identification information of each cluster head base station in the network, that is, second response information carrying identification information (2, 1) of the cluster head base station 21, according to the second request information, and the standby cluster head base station 12 establishes the inter-cluster routing list according to the second response information. And the standby cluster head base station 12 broadcasts the third request information, so that the base stations receiving the third request information, such as the second base station 13, the third base station 14 and the fourth base station 15 shown in the figure, return third response information carrying base station identification information, such as the identification information (1, 3) of the second base station 13, the identification information (1, 4) of the third base station 14 and the identification information (1, 5) of the fourth base station 15, according to the third request, and the standby cluster head base station 12 establishes an intra-cluster routing list according to the third response information.

Step 308, the standby cluster head base station 12 sends a bearer creation request to the cluster head base station 21 of the second base station cluster in the inter-cluster routing list according to the inter-cluster routing list, so that the cluster head base station 21 of the second base station cluster returns corresponding creation response information to create a direct bearer with the cluster head base station 21.

Step 309, the standby cluster head base station 12 sends, according to the in-cluster routing list, update information carrying the cluster head identification information, that is, update information carrying the identification information (1, 2) of the standby cluster head base station 12, to each base station in the in-cluster routing list, so that the second base station 13, the third base station 14, and the fourth base station 15 update the cluster head identification information in each routing list according to the identification information (1, 2).
