Description
Technical field
The present invention relates to mobile communication network technology, particularly relate to a kind of network-building method and device of communication network.
Background technology
In existing mobile communication system, according to the definition of 3GPP agreement, the networking structure relation of wireless communication system as shown in Figure 1:
Wherein, one or more logic district CELL can be divided under a base station BTS; Each CELL has a cellular global identity CGI.
The ownership BSC that each CELL is corresponding is defined in MSC.
There is following shortcoming in the networking technology of this existing network:
During a BSC fault, the base station BTS that this base station controller BSC connects all cannot provide Mobile Communication Service, and the time of generally repairing a BSC wants more than dozens of minutes often, even several hours, the network user caused under this BSC overlay area cannot communicate by for a long time.
Past is generally hundreds of carrier wave due to the capacity of base station controller BSC, and coverage is also smaller, and this shortcoming is also not obvious; But along with the development of technology, the capacity of base station controller BSC is also increasing, the capacity of a lot of Large Copacity base station controller BSC can reach 2000 multicarriers now, even reaches 3000 multicarriers.The coverage of such Large Copacity BSC is also more much bigger than past.This shortcoming seems obvious especially after Large Copacity base station controller starts application, brings very large threat to the reliability of wireless network.
Summary of the invention
The problem that the embodiment of the present invention will solve is to provide a kind of network-building method and device of communication network, by setting up BSC POOL, and set up BSC selection strategy, thus make after in BSC POOL, operation irregularity appears in some BSC, can accomplish that the business not affecting whole mobile communications network provides, do not change the coverage of wireless network, reach the effect improving mobile communications network reliability.
For achieving the above object, the embodiment of the present invention proposes a kind of network-building method of communication network on the one hand, comprises the steps:
Setting base station controller BSC selection strategy;
When the BSC operating state of in described communication network meets pre-conditioned, according to described BSC selection strategy, select a new BSC to replace described BSC and carry out work.
On the other hand, the embodiment of the present invention additionally provides a kind of network device of communication network, it is characterized in that, comprising:

Embodiment
The present invention is by setting up BSC POOL, and set up BSC selection strategy, thus make after in BSC POOL, operation irregularity appears in some BSC, can accomplish that the business not affecting whole mobile communications network provides, do not change the coverage of wireless network, reach the effect improving mobile communications network reliability.
As shown in Figure 2, be the network-building method of the embodiment of the present invention, a kind of communication network, for carrying out the reliability of lifting mobile communication network by setting up BSC POOL.By the BSCPOOL network-building method of the embodiment of the present invention, set up the mobile communications network comprising BSC POOL as shown in Figure 3, comprising:
Step S201, setting BSC selection strategy, determine, when the situation of operation irregularity appears in BSC, to select new BSC, replace fault BSC and carry out work.
In this step, also comprise and the multiple BSC under one or more MSC are divided into a BSCPOOL, in this BSC POOL, under normal condition, under each BTS only belongs to a BSC, and one or more BTS under a BSC, can be comprised, under each BTS, comprise multiple logic district CELL.As in figure 3, BTS1 only belongs to BSC1, and simultaneously, comprises BTS1 and BTS2 two BTS, and comprise CELL1 and CELL2 under BTS1 under BSC1.
In actual applications, set up BSC POOL under above-mentioned multiple MSC to be realized by MSC POOL.
On the other hand, in this step, said operation irregularity situation comprises:
A BSC breaks down, then the BTS belonging under this BSC all cannot normally work, and as in figure 3, BSC1 breaks down, then BTS1 and BTS2 all cannot normally work; Or,
Disconnecting between a BTS and ownership BSC, then this BTS can not carry out work under ownership BSC, but do not affect the work of other BTS under this ownership BSC, as in figure 3, disconnecting between BTS1 and BSC1, then BTS1 cannot continue to work under BSC1, but simultaneously, the work of BTS2 is unaffected.
In addition, if the BTS that the hydraulic performance decline of BSC to a certain extent or meet certain pre-conditioned, so belongs to this BSC also can select a new BSC to replace, to ensure the normal work of BTS.
Whether step S202, the BSC judged in BSC POOL exist fault, and distinguish the reason of fault when breaking down, and namely distinguishing is that connection fault between BSC fault or BTS and BSC result in this BSC operation irregularity.
If when the BSC in BSC POOL does not exist operation irregularity situation, proceed to step S205;
If the BSC in BSC POOL exists operation irregularity situation, and the reason of operation irregularity is BSC fault when causing, and proceeds to step S203;
If the BSC in BSC POOL exists operation irregularity situation, and the reason of operation irregularity is disconnecting between BTS and ownership BSC when causing, and proceeds to step S205.
Step S203, when a BSC breaks down, according to BSC selection strategy, in other BSC in BSC POOL, select the BSC that new, replace fault BSC, control all BTS in this fault BSC control range.
After replacement completes, be switched to step S205.
Step S204, when a BTS and ownership BSC between disconnecting time, according to BSC selection strategy, in other BSC in BSC POOL, select the BSC that new, replace this ownership BSC, control this BTS and carry out work, but simultaneously, do not change the ownership situation of other BTS under this ownership BSC.
After replacement completes, be switched to step S205.
Step S205, to communicate according to the matched rule of BSC and BTS.In above steps, the CGI that the community CELL under each BTS uses can not change.
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail:
