Background technology
TD-SCDMA (Time Division-Synchronization Code Division MultipleAccess, the TD SDMA access) multi-carrier district is meant in a sub-district and supports a plurality of carrier waves simultaneously, one of them is main carrier (TS0), and other carrier wave is auxilliary carrier wave.Because dedicated channel is configured on main carrier and the auxilliary carrier wave, and Common Control Channel can only be configured on the main carrier, can enlarge cell throughout (capacity) by increasing carrier wave not increasing number of cells, not influencing under the prerequisite of neighboring BS relationship and the covering of main carrier (TS0) public physic channel like this.At present, the 5MHz identical networking is the main carrier alien frequencies, and auxilliary carrier wave has obtained sufficient checking with systematic function frequently in try net.If auxilliary carrier wave damages, only influence the UE (User Equipment, subscriber equipment) that this auxilliary carrier wave has inserted, so influence less; If the main carrier resource is damaged, then Common Control Channel can't be used, and all standby UE can be affected in the sub-district, can't insert.
Damage for main carrier, a kind of processing mode is shown in Figure 1, and Node B (Node B) forces to discharge UE, deletion sub-district, rebuilds the sub-district mode by RNC (Radio Network Controller, radio network controller).This handles simple, but can cause all auxilliary carrier wave UE call drops, so this carrier failure recovers processing method business is had considerable influence.Also have a kind of mainly by Node B control main carrier fault recovery method: if Node B has idle carrier resource, then notify RNC to rebulid main carrier, influence only limits to main carrier UE call drop, and auxilliary carrier wave UE is unaffected; If Node B does not have idle carrier resource, then notify the auxilliary carrier wave UE of RNC migration to discharge to other auxilliary carrier wave or pressure, behind the auxilliary carrier wave of RNC deletion, rebulid main carrier by Node B, its influence also only limits to an auxilliary carrier wave and main carrier UE.
Rebulid main carrier process more complicated by Node B, need simulation RNC to initiate the business processing flow that a series of scripts such as Common transport channel foundation, Physical Shared Channel foundation, public broadcasting message recovery are initiated by RNC control.This processing mode has been broken " RNC management logic carrier resource, Node B managing physical resource " this network element division of labor principle, cause dividing the work between network element not clear, there is very big hidden danger, if initiate other operation flow in the middle of the RNC, then need a lot of abort branches, handle complexity, the stable difficult assurance of system.In addition, auxilliary carrier wave can be set up Common transport channel, Physical Shared Channel, the Node B of responsible physical resource management and do not know the business of these channel application only, and the resource race to control that Node B initiates not is that simple physical resource is seized, and therefore makes Node B realize this function and improper blindly.
To sum up, this mode of being seized auxilliary carrier resource or oneself being distributed idling-resource to realize that main carrier is rebuild by Node B has been broken " RNC management logic carrier resource; Node B managing physical resource " this network element division of labor principle, cause dividing the work between network element not clear, handle complexity, the stable difficult assurance of system.
Therefore, also there is defective in prior art, awaits improving and development.
