Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
At first need to prove, in embodiments of the present invention, the corresponding base station of aggregation cell, base station is corresponding a plurality of can resident carrier wave, in other words, have in the aggregation cell a plurality of can resident carrier wave.
In embodiments of the present invention, in any one aggregation cell can resident carrier wave (a base station correspondence can resident carrier wave) in other words, all need to be divided at least two TA.Need to prove that what base station can be in its correspondence can initiate paging to UE on the resident carrier wave.
Such as, an example of the embodiment of the invention can be dissimilar can being divided into respectively in the different TA by resident carrier wave in any one aggregation cell.That is to say, in each TA can resident carrier wave all be same type can resident carrier wave.With network environment shown in Figure 1 is example, supposing can resident carrier wave f1, f2 and f3 respective base station 1 (not illustrating among Fig. 1), can resident carrier wave f4, f5 and f6 respective base station 2 (not illustrating among Fig. 1), can resident carrier wave f7, f8 and f9 respective base station 3 (not illustrating among Fig. 1), wherein, f1, f5, f6 and f7 be same type can resident carrier wave, f4 and f8 be same type can resident carrier wave, f2, f3 and f9 be same type can resident carrier wave, f1 so, f5, f6 and f7 can be divided in the TA1, f4 and f8 can be divided in the TA2, f2, f3 and f9 can be divided in the TA3.
Further, the same type in certain or some aggregation cell can be divided in two TA by resident carrier wave at least.That is to say can being divided in a plurality of TA by resident carrier wave of a plurality of same types of certain or some base station correspondences.For example, suppose that base station 1 correspondence can resident carrier wave f1, f2 and f3, and f1, f2 and f3 be same type can resident carrier wave, wherein two can be divided in the same TA by resident carrier wave so, remaining one can be divided in another TA by resident carrier wave, also these three can be divided into respectively in three TA by resident carrier wave.By contrast, adopt the former dividing mode can reduce tracing section updating (TAU relatively, Tracking Area Update) operation, simultaneously, with respect to above-mentioned three modes that can resident carrier wave be divided in the same TA, adopt the former dividing mode can reduce taking relatively to the paging resource.So, when the same type of certain base station correspondence can resident carrier wave quantity more for a long time, can be with can being divided into uniformly in a plurality of TA by resident carrier wave of these same types, can reach like this and reduce the TAU operation and reduce the relative equilibrium that takies the paging resource.
In embodiments of the present invention, can adopt multiple mode distinguish can resident carrier wave type.For example, can according to the public priority of carrier wave distinguish can resident carrier wave type.Certainly, those skilled in the art can also adopt other modes distinguish can resident carrier wave type, illustrate no longer one by one here.
