Abstract

The invention provides a user data synchronization method, wherein when logging on both evolution network of system architecture (ENSA) and evolution network of former system architecture (ENFSA), user terminal selects to execute adherent operation or operation for updating route zone in ENSA or ENFSA. When user terminal carries out adherent operation or operation for updating route zone in execution network, the mobility management entity (MME) and user face entity (UFE) of the execution network inform not executing adherent operation or operation for updating route zone on MME and UFE. The invention prevents user data from clearing away so as to guarantee correct processing service.

Description

The method for synchronous of the user data during a kind of mobile terminal registers two networks simultaneously
Technical field
The present invention relates to the 3GPP network system, particularly the method for synchronous of the user data during mobile terminal registers two networks simultaneously.
Background technology
3GPP (3rd Generation Partnership Project; 3rd Generation Partnership Project) in order to strengthen the competitiveness of future network, study a kind of brand-new evolution network framework, comprising the Long Term Evolution (LTE:Long-Term Evolution) of System Architecture Evolution (SAE:System Architecture Evolution) and Access Network.
Wherein, the Access Network of evolution is called the UMTS Terrestrial radio access network (E-UTRAN:EvolvedUMTS Territorial Radio Access Network) of evolution, the packet core network framework of evolution comprises three logical functional entities of user's face anchor point (InterAS Anchor:Inter Access System Anchor) between Mobility Management Entity (MME:Mobility Management Entity), user entity (UPE:User Plane Entity) and the different access systems as shown in Figure 1.
Wherein, MME, be responsible for the mobile management of chain of command, comprise the management of user's context and mobile status, distributing user temporary identity signs etc. are corresponding to the control plane part of current GPRS (GPRS:(General Packet Radio Service)/universal mobile telecommunications system (UMTS:Universal Mobile Telecommunications System) internal system Serving GPRS Support Node (SGSN:ServingGPRS Support Node);
UPE, be responsible for initiating paging for downlink data under the idle condition, IP bearing parameter and the interior routing iinformation of network etc. are preserved in management, corresponding to the datum plane part of current GPRS/UMTS internal system SGSN and Gateway GPRS Support Node (GGSN:Gateway GPRS Support Node);
Inter AS Anchor then serves as the user's face anchor point between different access systems.
"Policy and Charging Rules Function entity (PCRF:Policy and Charging Rule Function) is used for policy control decision and flow based charging controlled function;
Home network server (HSS:Home Subscriber Server) is used for storing user subscription information.
3GPP is after having introduced the SAE/LTE technology, 3GPP communication system originally also will be in one time with new technology and deposit, in order to make better intercommunication between two or more technology, and reduce the signaling message under idle condition between these technology at wireless access, proposed three kinds of solutions at present following.
First kind of scheme:
As shown in Figure 2, be the SAE of first kind of scheme and the system architecture schematic diagram of Pre-SAE coexistence.Mainly be that user data is kept among the SGSN of preceding SAE (Pre-SAE) network, MME/UPE in the SAE/LTE network distributes Temporary Mobile Subscriber Identifier (TMSI:Temporary Mobile Subscriber Identity), and tracking area (TA:Tracking Area) is given UE; SGSN among the Pre-SAE has distributed Temporary Mobile Subscriber Identifier TMSI simultaneously, and route district (RA:Routing Area) gives UE.When the user moves around like this, no longer include new Routing Area Update in the RA of the TA of SAE and Pre-SAE, saved a part of signaling.
As shown in Figure 3, the particular flow sheet of in Pre-SAE network and SAE network, registering for UE.Among the figure, → be necessary process;
Figure GSB00000361869200021
Be optional process.As shown in Figure 3, concrete steps are as follows:
Step 1, subscriber equipment (UE:User Equipmet) SGSN in Pre-SAE sends register requirement (Register Request) message;
Step 2 is carried out safety function (Security Function); This process is an optional process;
Step 3 is registered (Register SGSN) in HSS with Pre-SAE SGSN;
Step 4, HSS inserts (Insert Subscriber Data) in Pre-SAE SGSN with this user's related data; Wherein, insert subscriber data message and have many;
Step 5, Pre-SAE SGSN sends and inserts user data affirmation (Insert Subscriber Data Ack) message to HSS;
Step 6, HSS sends accreditation verification (Register Confirm) message and gives Pre-SAE SGSN;
Step 7, Pre-SAE SGSN sends registration and accepts (Register Accept) message to UE;
Step 8, UE sends registration and finishes (Register Complete) message to Pre-SAE SGSN, and wherein, this message is optional message;
Step 9, UE detects other connecting system, and is linked in the SAE connecting system;
Step 10, UE sends registration (Register Request) message to SAE MME/UPE;
Step 11, SAE MME/UPE sends identification request (Identity Request) message and gives Pre-SAESGSN;
Step 12, Pre-SAE SGSN should user-dependent data send to SAE MME/UPE by identification response (Identity Response) message;
Step 13, SAE MME/UPE sends registration and accepts (Register Accept) message to UE.
Step 14, UE sends registration and finishes (Register Completc) message to SAE MME/UPE, and wherein, this message is optional message.
Second kind of scheme:
As shown in Figure 4, for having the SAE and the Pre-SAE symbiotic system configuration diagram of second kind of scheme now.This scheme mainly is that user data is kept among the MME/UPE of SAE/LTE network, and the MME/UPE in the SAE/LTE network has distributed TMSI separately, tracking area TA and route district RA to UE;
Under the optional situation, the SGSN among the Pre-SAE also can reallocate a TMSI to UE.When the user moves around like this, no longer include new Routing Area Update under the route district RA of the tracking area TA of SAE and Pre-SAE, saved a part of signaling.
If UE is registered among SAE MME/UPE and the Pre-SAE SGSN simultaneously, and SAE MME/UPE distribution T MSI, tracking area identification (TAI:Tracking Area Identity) are given UE, and Pre-SAE SGSN distribution T MSI, Routing Area Identifier (RAI:Routing Area Identity) are given UE.Register flow path Fig. 3 of the similar scheme one of this concrete flow process repeats no more here.
If UE is registered among SAE MME/UPE and the Pre-SAE SGSN simultaneously, in this registration process, have only SAE MME/UPE to distribute TMSI, a RAI, TAI to give UE.Concrete handling process is no longer stated here.
The third scheme:
This kind scheme mainly is that the user is registered in SAE, and in the Pre-SAE network, network issues TMSI (one or two), and UE is given in equal-cost route district tabulation (the one or more TA of one or more RA+).UE when mobile, does not need extra Routing Area Update signaling in these equal-cost route districts like this.
The logon mode of the logon mode of this scheme and scheme one and scheme two is similar, repeats no more here.
In the such scheme, Routing Area Update general reference in the Pre-SAE network Routing Area Update (RAU:Routing Area Update) and the tracing section updating (TAU:Tracking Area Update) in the SAE/LTE network.
Though above-mentioned three kinds of schemes have realized that subscriber equipment when mobile, has reduced relevant signaling message, especially Routing Area Update message in two kinds of networks.But, if residing in the network of certain wireless access technology A for a long time, the user carries out the periodicity Routing Area Update, will have a problem like that, promptly in another kind of wireless access technology B, this user's data may be eliminated owing to timer expiry causes user data.Like this, when user terminal moves into wireless access technology B, owing to do not require to carry out Routing Area Update, this user data not in this technology, the business operation of initiation will be failed.
