Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of paging method, system, equipment of the core network andDual link gateway (DCGW, DualConnectivityGateWay).
Background technology
Fig. 1 is the general frame of the medium-term and long-term evolution of prior art (LTE, LongTermEvolution) systemSchematic diagram. As shown in Figure 1, LTE system comprises: mobile management entity (MME, MobilityManagementEntity), gateway (SGW, ServingGateWay), subscriber equipment or be calledTerminal (UE, UserEquipment) and base station (eNB, eNodeB). Wherein, between eNB and UEBeing UU interface, is S1-MME interface between eNB and MME, between eNB and SGW, is S1-UInterface is X2-U and X2-C interface between eNB; Here, S1-MME interface is the S1 of control planeInterface; X2-U interface is the X2 interface of user's face, and X2-C interface is the X2 interface of chain of command.
In LTE system, the protocol stack of S1-MME interface is divided into following protocol layer: L1 from the bottom upAgreement, L2 agreement, Internet Protocol (IP, InternetProtocol), SCTP (SCTP,StreamControlTransmissionProtocol), S1 Application Protocol (S1-AP, S1-ApplicationProtocol). In LTE system, the protocol stack of S1-U interface is divided into following protocol layer from the bottom up:L1 agreement, L2 agreement, User Data Protocol/Internet Protocol (UDP/IP), GPRS Tunnel Protocol-useFamily face (GTP-U, GPRSTunnelingProtocol-Userplane).
At present, due to the scarcity of frequency spectrum resource, and the surge of mobile subscriber's large flow business, in order to increaseAdd user throughput and strengthen travelling performance, the demand day that adopts high frequency points to carry out focus covering as 3.5GHzBenefit obviously, adopts lower powered node to become new application scenarios. But, due to the signal attenuation of high frequency pointsMore severe, and the coverage of lower powered new community is smaller, and do not stand altogether with existing communityPoint, therefore, if user moves between these new communities, or Xin community and existing community itBetween move, must cause handoff procedure frequently, make between base station frequently to transmit user profile, thereby rightCore net has caused very large signaling to impact, and then has contained the introducing of a large amount of cellulors of wireless side base station. CauseThis, proposed the technical scheme of dual link.
Fig. 2 is a kind of cellulor base station system general frame schematic diagram. As shown in Figure 2, cellulor base station systemTurnkey is drawn together: MME, SGW, UE and eNB. Between UE and eNB, be UU interface, MeNB andBetween MME, being S1-MME interface, is S1-U interface between MeNB, SeNB and SGW, eNBBetween be Xn interface. In cellulor base station system, user data can be from core net by main eNB(MeNB, MastereNB) is issued to user, also can from core net by from eNB (SeNB,SecondaryeNB) be issued to user. When user is after MeNB access, can be by adding, amendment,Or the mode of deleting SeNB realizes dual link.
Meanwhile, under dual link framework, change hand off signaling under scene in order to reduce the constant and SeNB of MeNBTo the impact of core net, may introduce DCGW, this node can be newly-increased network node, also canBe positioned at MeNB, also can be positioned at existing femto gateway (HeNBGW). At Home eNodeB (HeNB)The duplex of disposing connects and realizes under scene, and HeNB also can be used as MeNB/SeNB, therefore has HeNBGWThe scene of disposing.
Under the little base station system shown in Fig. 2, owing to having introduced the concept of MeNB and SeNB, also introduceThe concept of DCGW, be problem demanding prompt solution so how core net realizes calling optimization.

Here, step 701～702nd, sets up the process of interface, Ke Yichong between SeNB and HeNBGWRealize with existing S1 interface Establishing process.
S1 interface is set up in response and is comprised DCGW relevant information; Wherein, DCGW relevant information canComprise DCGW identification information, such as DCGWID.
Step 703:HeNBGW preserves the map information of SeNB and DCGW, performs step afterwards 704;
Here, map information comprises: the information of SeNB and DCGW relevant information;
Particularly, be positioned at the information that the DCGW of HeNBGW preserves the SeNB self connecting, fromAnd formation map information;
Wherein, the information of SeNB can comprise the SeNB relevant configuration information such as SeNBID; Map informationIn DCGW relevant information can comprise DCGW identification information, such as DCGWID.
Step 704:MME by and HeNBGW between S1 interface obtain DCGW relevant information;
The message of the carrying DCGW relevant information that here, S1 interface transmits can be public S1 interfaceMessage can be also the special S1 interface message of UE.
Wherein, public S1 interface message can adopt following one or more: S1 sets up request message, baseThe configuration update message of standing; The special S1 interface message of UE can adopt following one or more: INITIALUEMESSAGE message, UPLINKNASTRANSPORT message.
When practical application, the message that S1 interface transmits is not limited to the above-mentioned S1 interface message of enumerating.
The DCGW relevant information that step 705:MME preservation connects self and DCGW placeMeNB information, performs step 706 afterwards;
Here, MeNB information can be MeNBID etc.
Step 706: in the time that MME initiates UE beep-page message, MME disappears to HeNBGW distributing pagingBreath;
Here, MME, except according to TAI list, can also come according to the DCGW relevant information of preservingCarrying out beep-page message issues; Such as: according to DCGW relevant information, beep-page message is sent to HeNBGW。
In the beep-page message sending to HeNBGW, comprise DCGW relevant information.
Step 707:HeNBGW receives after beep-page message, and beep-page message is sent to corresponding DCGWThe SeNB connecting.
Particularly, HeNBGW is according to the SeNB preserving and the map information of DCGW, by beep-page messageThe SeNB that sends to corresponding DCGW to connect.
Here, when the method for the present embodiment is during for the paging situation of LIPA/SIPTOLN business, HeNBGW (DCGW) can further optimize paging range, thereby has obvious beneficial effect. Give an exampleSay, when the closing of the LIPA/SIPTOLN business of UE established L-GW and be positioned at SeNB, MME can pass throughThe method of the present embodiment is paging UE under DCGW scope, and DCGW can basisThe closing of LIPA/SIPTOLN business established L-GW address information and further optimized paging range, that is: a pinLIPA/SIPTOLN business is closed and established the SeNB that L-GW is positioned at and carry out issuing of beep-page message.
