Abstract
The method comprises: when the first base station gets the information that is the first base station stops its work, it sends the information to the second base station controller, and closes the power transmission of the base station; after the second base station controller gets the information, it informs the second base station to work. The invention reveals a dual-network backup system of mobile communication system, which uses an added information channel between BSCs to let one time point only have one network at working so as to reduce energy loses of system. Because one base station can uses the working frequency range of another base station, the occupation of frequency resources is reduced. Because there is only one network at working, the switch between two networks will not happens, so as to avoid the rising of system signaling traffic and the degradation of voice quality.
Description
Technical field
The present invention relates to moving communicating field, particularly the two net redundancy techniques in the moving communicating field.
Background technology
Gsm mobile communication system is that terminal, base station sub-system (BSS), network subsystem (NSS) and operation support subsystem (OSS) to constitute by travelling carriage (MS).Wherein BSS is made of BTS and BSC, and NSS is made of network elements such as MSC, OMC.As shown in Figure 1, wherein,
BTS is a base station equipment, finishes wireless coverage, and signal amplifies, and power emission etc. link to each other with MS by aerial Um Interface.
BSC is a base station controller, finishes the control at least one BTS.
MSC is a mobile switching centre, finishes the exchange of information, links to each other with BSC by the A interface.
OMC is an operation maintenance center, is used for the man-machine window to the operation of BSC.
Above-mentioned is example with the gsm system just, in cdma system, and the above-mentioned identical function that has said network element to realize equally; In WCDMA, Node B can realize the function of above-mentioned BTS, and RNC can realize the function of above-mentioned BSC, and MSC has the function of above-mentioned MSC, thus suitable application area of the present invention can be in GSM, CDMA, the WCDMA system any, following still is example with the gsm system.
In the gsm wireless network construction, consider the combined reliability factor of network construction, in some environment or occasion, can adopt two net redundancy techniques further to improve the reliability of wireless coverage network.Two net redundancy techniques generally need active and standby two cover networks, and when a cover network portion equipment or an armamentarium fault, the equipment of another set of network can continue to provide service.Can not influence system's operation.
The mode of operation of two at present net backups is as follows:
Core net is independent, and BSC is divided into active and standby usefulness, and the two cover base stations that cover with the location are connected on respectively on the active and standby BSC, and two networks are all in running order.Two sub-districts that are similar to general network overlap, and as shown in Figure 2, the cell range that two cover BTS cover overlaps.
When major network breaks down, the major network sub-district does not have level output, and terminal can not receive the existing network signal, can temporarily break away from network, does not have level to show on the terminal.But owing to be equipped with net always in transmitting power, terminal is received the signal that is equipped with the net emission.
Active and standby network can make the preferably main network of using of terminal by the network parameter setting.Can be resident by the sub-district of cell reselection parameters control terminal.When the main network failure, terminal used can not receive main signal with network, can only select backup network, in backup network work.When the main network recovery of using, terminal is chosen main resident with network according to network parameter.
Existing terminal switches to the flow process that is equipped with net by major network and roughly comprises:
The downlink failure criterion is based on downlink signaling link failure counter.When terminal resides in a sub-district, the message that sends by decode system is determined whether operate as normal of system, if a period of time can not receive the information that system sends, cause downlink signaling link failure counter overtime, the starting terminal cell re-selection procedure, can be equipped with the network control parameter of broadcasting in the net cell system message by being provided with, carry out the sub-district gravity treatment according to the C2 principle; Owing to net the power that the base station sends fully, terminal detects net signal of base station fully, selects to reside in to net the sub-district fully.
When the major network fault is eliminated,, according to the C2 principle gravity treatment is carried out in the sub-district terminal is resided in the major network sub-district by the network control parameter of in the major network cell system message, broadcasting.
In the terminal of major network conversation, if the major network fault, terminal meeting call drop arrives standby sub-district by gravity treatment again for just.For the terminal in conversation not, during the major network fault, terminal shows is received signal from having to nothing, and then to the process that has.
What two at present net backups were adopted is redundant soverlay technique.Be that areal adopts two cover base stations to cover, the structure of two cover base stations is identical and be based upon same place, and works simultaneously, forms relation one to one.In order to satisfy the channeling requirement, the working channel difference of this two covers base station is so also claim double frequency redundant soverlay technique.When the major network operate as normal, be equipped with the also necessary transmitting power of net, need expend lot of energy.
It is more that another problem that this two net covers is that frequency resource need take, so the frequency range utilance is low, the network planning is difficult.Improved the difficulty of the network optimization.Terminal adopts double frequency to switch, and may influence speech quality, causes call drop easily, and easily causes rising of system signaling traffic to increase.
