Abstract
Disclosed is a method for reducing paging signaling overheads. According to the method, communication is realized in the manner that a cell where a terminal to be paged is located at present is positioned by using a terminal direct-connection D2D mechanism through an MME. The functions of the MME are enhanced first so that the MME can achieve the functions that after D2D connection is established between an idle mode terminal and a connection mode terminal which are close to each other, the connection mode terminal can report a Cell-ID of a cell where the idle mode terminal is located to the MME through a base station; thus, when downlink data of the idle mode terminal arrive at a network side, the MME only initiates paging to the cell where the idle mode terminal is located, therefore, the paging signaling overheads can be lowered, signaling processing loads of the base station can be reduced, and paging efficiency can be improved. The method is applied to the situation that the idle mode terminal and the connection mode terminal are located in the same cell or located in two adjacent cells respectively, wherein D2D connection is established between the idle mode terminal and the connection mode terminal.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and Examples, technical solution of the present invention is described in further detail.
The present invention is a kind of communication means that reduces the call signaling expense: by Mobility Management Entity MME(Mobility Management Entity) utilize D2D mechanism directly to locate paged terminal community, current place and realize communication.The method is the function that first strengthens MME, can realize following function: after the idle mode terminals of close together and connection mode terminal are set up D2D and be connected, the connection mode terminal can report MME by base station by the cell ID Cell-ID of community, idle mode terminals place; Like this, when the downlink data of the available free mode terminal of network side arrives, MME only initiates paging to this community, idle mode terminals place, and to reduce the call signaling expense, the signaling that reduces base station is processed load, improves paging efficiency.
Referring to Fig. 3, introduce two kinds of application scenarioss of the inventive method:
Fig. 3 (A) sets up the situation that idle mode terminals that D2D connects and connection mode terminal are arranged in same community: in " D2D is connected foundation " message, the connection mode terminal reports to MME by the current persistent district of the idle mode terminals same services community of the current place of connection mode terminal (with).Like this, when network side needs the paging idle mode terminals, only need to send " paging request " message to the current resident community of idle mode terminals, then by this Cell Broadcast CB " paging " message.
Fig. 3 (B) sets up the situation that idle mode terminals that D2D connects and connection mode terminal lay respectively at two neighbor cells: in " D2D is connected foundation " message, the connection mode terminal reports to MME by the current persistent district of idle mode terminals (Serving cell that is different from the current place of this connection mode terminal).Like this, when network side needs the paging idle mode terminals, only need to send " paging request " message to the current resident community of idle mode terminals, then by this Cell Broadcast CB " paging " message.
Referring to Fig. 4 (A), introduce the concrete operation step of the inventive method at Fig. 3 (A) application scenarios:
(1) idle mode terminals UE2 sets up D2D with connection mode terminal UE 1 and is connected, and mutually exchanges Cell-ID;
(2) connection mode terminal UE 1 sends " D2D connects foundation " message to the place cell base station, carries the Cell-ID of community, idle mode terminals UE2 place in this message;
(3) base station is transmitted to MME by " D2D connects foundation " message;
(4) when the downlink data of the available free mode terminal of network side arrives, MME sends " paging request " message to this target terminal UE2 place cell base station, carries target terminal UE2 sign in this message, and starts the T1 timer;
(5) target terminal UE2 place cell base station receives this " paging request " message, broadcast " paging " message in cell coverage area;
(6) after paged idle pulley target terminal UE2 receives according to self identification " paging " message that current resident cell base station sends, to this cell base station, send " service request " message, should " paging " message with response;
(7) this cell base station forwards " service request " message to MME;
(8) MME stops the T1 timer, the paging success.
The sequential that Fig. 4 (B) shows is exactly the concrete operation step of the inventive method at Fig. 3 (B) application scenarios, the difference of itself and Fig. 4 (A) is just: connection mode terminal UE 1 and idle mode terminals UE2 lay respectively at two neighbor cells, therefore MME is after knowing the current persistent district ID of UE2, when the paging of initiating for UE2, directly " paging request " message is sent to the current area of UE2, no longer need it is sent to the current area of UE1 simultaneously.Remaining sequential is all identical.Therefore repeat no more.
Referring to Fig. 5, introduce in the inventive method and report MME to remove two operating procedure sequential that D2D connects.
Fig. 5 (A) shows: when idle mode terminals UE2 is connected with connection mode terminal UE 1 releasing D2D, both are positioned at same community, now by connection mode terminal UE 1, to the place cell base station, send " D2D connects releasing " message, this base station should " D2D connects releasing " message be transmitted to MME again.
Fig. 5 (B) shows: when connection mode terminal UE 1 and idle mode terminals UE2 are positioned at neighbor cell, send " D2D connects releasing " message by UE1 to the place cell base station, be transmitted to UE2 place cell base station eNodeB2 by this base station eNodeB 1 by X2 interface again, then by UE2 place cell base station eNodeB2 again should " D2D connects releasing " information reporting to MME.
Referring to Fig. 6 (A) and (B), introduce respectively the following content of operation of the inventive method: when idle mode terminals UE2 and connection mode terminal UE 1 removed after D2D is connected, network side when the downlink data of available free mode terminal UE2 arrives again, has the method for following two kinds of paging idle mode terminals UE2:
For the business of delay sensitive, MME adopts traditional paging method, to all communities in the tracking terminal district, initiates paging (as shown in Figure 2).
For the insensitive business of time delay, at first MME initiates paging to the community, idle mode terminals UE2 place originally reported, and starts the T2 timer simultaneously; Now can produce the paging flow process of two kinds of different sequential: within the timer T2 stipulated time, MME receives page response and MME does not receive page response.
The first is in T2 timer setting-up time, MME receives the sequential of page response as shown in Fig. 6 (A): MME only sends to " paging request " message and removes the last resident community of the front UE2 of D2D connection, this cell base station is broadcasted " paging " message of carrying the target terminal sign in its coverage, after paged idle pulley target terminal receives this " paging " message according to self identification, send " service request " message to cell base station, should " paging " message with response.This cell base station forwards " service request " message again to MME, and MME receives the operation that this " service request " message just stops the T2 timer.
The second is when T2 timer setting-up time, MME does not receive the sequential of page response as shown in Fig. 6 (B): now, because " service request " message from UE2 is not received in the last resident community of UE2 before removing the D2D connection, illustrate that UE2 has left the Liao Gai community, thereby MME need to initiate pagings to other communities in the tracking area of UE2.It should be noted that: the timing duration of this T2 timer is less than the T1 timer.
Especially, it should be noted that: " D2D connect set up message " that the present invention mentions, " D2D connect remove message ", " paging request message ", " beep-page message " and " service request information " be all for describing the function of related protocol, not corresponding with the concrete message in the communication protocol of prior art or actual standard.
