In the embodiment of the present invention, the transmission between the EMS and the base station may be divided into two transmission processes: transmission between the EMS and the BTS-H, and transmission between the BTS-H and the BTS-L. Between the EMS and the base station In the case where the communication network is complicated, the BTS-H1 in FIG. 1 and the BTS-L1 to BTS-L3 controlled by the same are used as an example, and a call connection is established between the EMS and the devices of the three base stations in the prior art.

This case can flexibly adjust the BTS-H to which a BTS-L belongs. It does not need to re-adjust the hardware installation, which brings flexibility to network operation and maintenance. For example, when the operator provides communication services for two customers, there are fewer BTS-L devices, and the operator divides all the BTS-Ls of the two enterprises into one BTS-H. With the increase of BTS-L equipment, the EMS can add a BTS-H to the BTS-H server, and assign the BTS-Ls of the two enterprises to different BTS-Hs to implement independent management of BTS network elements of different enterprises. .

For a better understanding of the embodiments of the present invention, the adjustment process of the base station system is specifically described by taking FIG. 1 as an example.

The EMS sends a first adjustment command to the BTS-H1 according to the service requirement, and the first adjustment command carries the parameter information of the BTS-L4. After receiving the first adjustment command sent by the EMS, the BTS-H1 establishes a connection with the BTS-L4, as shown in FIG. 6, which is a schematic structural diagram of an adjusted base station system according to an embodiment of the present invention.

According to the needs of the service, three BTS-Ls are added to the base station system, namely BTS-L6, BTS-L7, and BTS-L8. The EMS establishes BTS-H3 on the server where BTS-H1 and BTS-H2 are located. The EMS sends a second adjustment command to the BTS-H2 and a third adjustment command to the BTS-H3. The second adjustment command carries parameter information of the BTS-L6, and the third adjustment instruction carries parameter information of the BTS-L7 and the BTS-L8. The BTS-H2 receives the second adjustment command sent by the EMS, and establishes a connection with the BTS-L6 based on the second adjustment instruction. The BTS-H3 receives the third adjustment command sent by the EMS, and establishes a connection with the BTS-L7 and the BTS-L8 respectively based on the third adjustment instruction. FIG. 7 is a schematic structural diagram of an adjusted base station system according to an embodiment of the present invention.

In the embodiment of the present invention, the base station system includes at least one BTS-H for performing signaling interaction with the EMS, and controlling each BTS-L operation connected thereto, and at least one for each BTS-H connected to the baseband BTS-L for processing signals and RF signals, compared to the prior art All modules of a base station are centrally deployed on one device. When adjusting the control modules for managing the three functional modules of the transmission module, the baseband module and the radio frequency module, it is only necessary to change the BTS-H that controls the BTS-L to operate. There is no need to redeploy hardware, which increases the flexibility of adjusting the base station system, saves a lot of manpower and material resources, and increases the flexibility of network operation and maintenance.
