The present invention will be further described in detail below with reference to the accompanying drawings.

Embodiment 1:

Referring to FIG. 2, the load message forwarding method provided in this embodiment includes:

S202: The source base station sends a resource status request message carrying the target base station identification information to the third-party base station through a communication interface between the source base station and the third-party base station, and receives, by using the communication interface, the third-party base station according to the target base station. Identifying a resource status response message of the target base station obtained by the information; the resource status request message is a request message of load information of the target base station;

S204: The source base station manages its resource status according to the resource status response message; the resource status response message is load information of the target base station; specifically, the source base station is configured according to the resource status response message to the base station. Load balancing is performed, and the load balancing includes: balancing of hardware load, transmission load, or wireless air interface resource load; and the execution manner thereof includes: reducing the load by reducing the service or the like in the case where the load is too high; In the case of a low level, the load is increased by increasing its service, etc., so that the load in the entire base station is balanced.

Preferably, in step S202, the source base station sends the resource status request message carrying the identity information of the target base station to the third-party base station through the communication interface between the source base station and the third-party base station, including: the source base station will carry the target base station. The resource status request message of the identification information is sent to the third party base station through the X2 interface between the source base station and the third party base station. In this embodiment, the description is mainly directed to message interaction between the base stations in the LTE communication system through the communication interface X2 interface. In the present specification, the specific implementation manner is directed to the message in the LTE system. The description of the transmission is carried out, but this solution is not only for the LTE system, but also for other communication systems.

Before the source base station sends the resource status request message carrying the identifier information of the target base station to the third-party base station by using the communication interface between the source base station and the third-party base station, the method further includes: determining, between the source base station and the target base station, Whether the communication interface communicates normally; when the communication interface between the source base station and the target base station fails to communicate normally, the source base station sends the resource status request message to the first through a communication interface between the source base station and the third-party base station Three-party base station. Preferably, determining whether the communication interface between the source base station and the target base station is normal communication includes determining Whether the X2 interface between the source base station and the target base station communicates normally includes: determining whether a communication connection of the X2 interface is established between the source base station and the target base station; further, establishing an X2 interface between the source base station and the target base station In the case of a communication connection, it is determined whether there is a fault in the X2 interface between the two base stations; the reason for the fault is that the line is broken, etc.; the communication connection of the X2 interface or the X2 interface is not established between the source base station and the target base station. In the case that the communication connection is faulty, when the source base station needs to acquire the resource status message of the target base station, the resource status request message needs to be forwarded through the third-party base station.

Preferably, the resource status request message includes a load information request; the resource status response message includes load information; and the source base station manages the resource status according to the resource status response message in step S204, the source base station according to the The resource status response message manages the equilibrium state of its load.

For example, in the LTE system, when a resource status request message is sent to another base station, the ECGI (E-UTRAN Cell Global Identifier) information of the target base station is carried, and The ECGI information is different. Therefore, when the third-party base station receives the resource status request message sent by the source base station, it will determine whether it is the base station according to the ECGI information in the message, and if it is not its own base station, The resource status request message is forwarded through the X2 interface; specifically, the following static configuration and dynamic selection may be adopted for the selection of the third-party base station.

基站ABase station A	基站BBase station B	基站CBase station C
基站ABase station A	基站CBase station C	基站DBase station D

Dynamic selection method: the network element management layer helps the selection, and the network element management layer to which the source base station belongs can select a third-party base station according to the configuration of the X2 interface between the base stations, or select and the source base station according to relevant performance statistics. The target base station has a third-party base station with X2 interface statistics, and the specific selection policy is not limited.

The source base station starts the timing by transmitting the resource status request message carrying the identifier information of the target base station to the third-party base station through the communication interface between the source base station and the third-party base station, and does not receive the resource when the timing exceeds the preset time. After the status response message, the resource status request message is resent or the management of the resource status is stopped. In this embodiment, it is determined whether the resource status request message is successfully sent by setting a time, or whether the resource status response message sent by the target base station encounters an obstacle; when the timeout has not received the corresponding resource status response message. Retrieve the information it needs by resending the resource status request message.
