Problems solved by technology

[0007] 1) The RRU has both a client module that communicates with the BBU and an operation and maintenance server module that communicates with the LMT, which increases the complexity of the RRU code;
[0008] 2) It is very difficult for the client module communicating with the BBU in the RRU and the operation and maintenance server module communicating with the LMT to work together;
[0009] 3) An operation and maintenance client communication module should also be developed in LMT, which will increase the development workload of the entire system.
[0010] 4) The LMT interface is not separated from the operation and maintenance function modules, resulting in a large workload for subsequent maintenance

Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] The structure of the preferred embodiment of the present invention is as figure 1 shown, including:

[0039] A remote radio unit with a client module, a baseband control unit with a server module, and a local maintenance terminal, the server module of the baseband control unit is connected to the client module of the remote radio unit;

[0040] The local maintenance terminal has a server module, and the server module of the local maintenance terminal is connected to the client module of the radio remote unit; and the communication between the server module of the local maintenance terminal and the client module of the remote radio unit The method is the same as the communication method between the server module of the baseband control unit and the client module of the remote radio unit.

[0041] With this structure, the RRU does not know whether it i...

Abstract

The invention is used for solving the issue of currently-used technology that is to use two different modules to make connection to LMT and BBU so as to cause complexity of system. The local maintenances module comprises a server side module connected to a client side module of RF far end unit; both the server side module in the local maintenances terminal and the client side module in the far end unit have same communication mode.

Description

technical field [0001] The invention relates to a device for realizing maintenance of a remote radio frequency terminal, in particular to a device for realizing a local maintenance terminal to maintain a remote radio frequency terminal. Background technique [0002] Remote radio has gradually developed into a trend of wireless communication system architecture. Radio remote refers to: separate the radio frequency unit from the base band control unit (Base Band Unit, hereinafter referred to as BBU), and connect the two through long-distance transmission means (optical fiber or cable), and then place the radio frequency unit in various required places. The place is called a radio remote unit (Radio Remote Unit, hereinafter referred to as RRU). [0003] The advantage of this architecture is that the two independent parts are separated and developed independently, which not only reduces the cost, but also improves the flexibility of networking and facilitates engineering instal...
