Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
A kind of paging method, is applied to mobile management entity, comprises as shown in Figure 1:
Step 11, the target BS being Terminal for service to the last time sends the first paging request, make described target BS terminal described in paging after receiving described first paging request, and described first paging request is forwarded to adjacent with this target BS and with the base station that described target BS is connected by X2 interface, make terminal described in the base station calling adjacent with this target BS.
Consider that the base station that X2 interface is connected can directly be set up alternately, therefore the first paging request can be transmitted to the base station connected by X2 interface by target BS of the present invention, therefore effectively can alleviate the signaling traffic load of S1 interface; Further, the present invention is the target BS of Terminal for service and the base station common call terminal adjacent with this target BS by the last time, therefore has very high paging success rate.
Obviously, in the above embodiment of the present invention, described first paging request is forwarded to the base station adjacent with this target BS by X2 interface by described target BS.The base station connected due to X2 interface generally all has overlapping covered (namely the overlay area of two base stations is middle does not exist gap), therefore extremely meets the paging requirement of terminal in moving process.
In addition, as shown in Figure 1, in the above embodiment of the present invention, described paging method also comprises:
Step 12, when not receiving the success response for described first paging request, all base stations within the scope of the tracking area that described terminal is corresponding send the second paging request, make terminal described in all base station callings within the scope of described tracking area.It is pointed out that step 12 is call terminal method of the prior art.
Particularly, described second paging request is paging PAGING message, and it carries the information list of described tracking area.The information list (namely this area is called TA LIST) that the PAGING message that it may be noted that carries tracking area is prior art.
In addition, for avoiding introducing new message, the instruction that target BS can identify can be added be used as the first paging request on PAGING message basis, namely described first paging request is paging PAGING message, it carries the information list of described tracking area, the information list of wherein said tracking area comprises a forwarding instruction, is used to indicate described target BS and described first paging request is forwarded to base station that is adjacent with this target BS and that be connected by X2 interface with described target BS.
In addition, the present invention also provides a kind of paging method, and be applied to the last target BS to described Terminal for service, as shown in Figure 2, described method comprises:
Step 21, receives the first paging request for terminal;
Step 22, terminal according to described first paging request paging, and described first paging request is forwarded to adjacent with described target BS and with the base station that described target BS is connected by X2 interface, make terminal described in the base station calling adjacent with described target BS.
Below paging method of the present invention is described in detail:
As shown in Figure 3, MME(its can implement the paging method being applied to mobile management entity provided by the invention) when needs initiate to carry out paging to mobile terminal UE 1, from the last business of preserving before this (as call, online etc.) relative recording, first know that the last time provides the target BS of service for UE1.MME is knowing that the last time of mobile terminal is for after mobile terminal provides the target BS eNB1 of service, sends the first paging request by S1 interface to eNB1; ENB1, after receiving the first beep-page message, forwards the first paging request by X2 interface to eNB2, eNB3 and eNB4; ENB1, eNB2, eNB3 and eNB4, to paging UE1 in the district covered separately, if confirm UE1, then to send to MME and the first paging corresponding successful page that disappears responds; MME, after receiving and successfully exhaling response, can think this paging success, without the need to as prior art, and all base stations transmission paging requests within the scope of the tracking area that each tracking area identification is corresponding in the tracking area list that UE1 is corresponding; If eNB1, eNB2, eNB3 and eNB4 are after receiving the first paging request, in the region covered separately, do not determine UE1, then MME can not receive successful page and responds and think this paging failure, like the prior art, all base stations within the scope of the tracking area that each tracking area identification is corresponding in the tracking area list that UE1 is corresponding send the second paging request, and UE1 is determined in the base station receiving the second paging request afterwards in each self-corresponding overlay area.
In sum, the present embodiment can alleviate the signaling traffic load of S1 interface effectively, and in first time paging request, has high paging become rate.
In addition, the present invention also provides a kind of paging equipment, is applied to mobile management entity, and as shown in Figure 4, it comprises:
