Description
Technical field
The present invention relates to technical field of communication, particularly, relate to a kind of network log-out method and dual-mode user device.
Background technology
In order to keep the competitiveness of 3-G (Generation Three mobile communication system) in the communications field, third generation partner program (3rd Generation Partnership Project, abbreviation 3GPP) the standard operation group just is being devoted to the research of (Evolved Packet System is called for short EPS) of evolution grouping domain system.Whole EPS system mainly comprises universal terrestrial access network (the Evolved Universal Terrestrial Radio Access Network of evolution as shown in Figure 1, be called for short E-UTRAN) and packet-based core networks (Evolved Packet Core, abbreviation EPC) two parts of evolution.The EPC of this system can support the user from global system for mobile communications enhanced data rates for gsm evolution entity wireless access network (Global System for MobileCommunication Enhanced Data Rate for GSM Evolution radio accessnetwork, be called for short GERAN) and the access of universal land radio access web (Universal TerrestrialRadio Access Network, abbreviation UTRAN).
In the EPC packet-based core networks, comprised home subscriber server (HomeSubscriber Server, be called for short HSS), mobility management unit (MobilityManagement Entity, be called for short MME), gateway (Serving Gateway, be called for short S-GW), grouped data network gateway (Packet Date Network Gateway, be called for short P-GW), service universal grouping wireless business supporting node (Serving GeneralPacket Radio Service Support Node, be called for short SGSN) and strategy and charging regulation function entity (Policy and Charging Enforcement Function is called for short PCRF).
In the EPS system,, introduced the function that the idle pulley signaling reduces (Idle modeSignaling Reduction is called for short ISR) in order to reduce the space interface signaling between subscriber equipment (User Equipment is called for short UE) and the core net.After activating the ISR function, have the UE of UTRAN/GERAN and E-UTRAN access function simultaneously, can be registered to MME and SGSN simultaneously.Therefore, when UE is mobile under two kinds of different Access Networks, UE can not initiate mutual radio access technologies (inter Radio Access Technology, abbreviation inter-RAT) Routing Area Update (Routing Area Update, be called for short RAU) or tracing section updating (Tracking Area Update, be called for short TAU), thus unnecessary signaling reduced.
At present, the schematic flow sheet that UE activates ISR as shown in Figure 2, Fig. 2 supposes that it is by the E-TURAN access network that UE begins, if earlier similar from UTRAN/GERAN access network situation, the flow process that UE activates ISR comprises:
Step 201, UE registers to MME by E-UTRAN, if UE has effective global unique temporary identity (Globally Unique Temporary Identity, be called for short GUTI) or packet TMSI (Packet-Temporary MobileSubscriber Identity, be called for short P-TMSI), then in request, carry P-TSMI or GUTI;
Step 202, MME checks UE and passes through, and after HSS obtains the necessary steps such as subscription data of UE, to UE transmission registration acceptance response, if MME has distributed new S-TMSI for this UE, then carries this parameter in the response;
Step 203 if UE has available P-TMSI, then is not designated it and upgrades.Because variation may take place in carrying after the attach process, then this moment, the UE sign oneself need be carried out ISR " ISR Syn " synchronously;
Step 204, UE moves in the route district of UTRAN/GERAN, and UE initiates RAU to SGSN, carries S-TMSI in the request, " ISR Syn " sign, and the network capabilities of UE (supporting the ISR function).If UE has effective P-TMSI also to need to be included in the request;
Step 205, SGSN obtains the contextual information of UE to MME;
Step 206, MME finishes UE after the various verifications, returns the contextual information of this UE to SGSN.If this MME supports the ISR function, comprise parameter " ISR Capability " in this response and indicate support ISR;
Step 207, SGSN checks whether to need to reselect S-GW, if do not need and SGSN supports ISR, this SGSN thinks that the ISR function can activate so.Confirm to add in the response ISR indication at context, notice MME can continue to safeguard the context of this UE;
Step 208, SGSN also need activate ISR by ISR sign notice S-GW in bearer update.Equally, SGSN notifies HSS to need two registrations in position updating request, and does not trigger the canceling position of HSS to MME;
Step 209, SGSN sends RAU to UE and accepts message, wherein comprises ISR and activates indication, has distributed P-TMSI if SGSN is UE, then also comprises this parameter in the request.
For the user that ISR activates, SGSN and MME must be connected to same S-GW, and need this UE of notice S-GW to activate ISR, notify this UE of HSS all to register in two kinds of access networks simultaneously.If UE is under the idle pulley, when having downlink data to arrive, need be at two these UE of area paging.
The inventor finds that present UE activates the process of ISR, exists following defective at least in realizing process of the present invention:
For the UE that has two kinds of access capabilities simultaneously, may have following scene: the initial hope of user can be used two kinds of access technologies, and activated the ISR function in the zone that two kinds of networks all cover, but because user's needs (as factors such as rates), the user wishes at a time to close a kind of access module on the UE, promptly only use single access way, but present processing procedure can't not have the ISR ability by informing network UE.
In the said process,, thus, may cause the mistake of processing such as follow-up paging, the perhaps waste on the signal resource because the UE ability (possessing the ISR ability) that the ability (not possessing the ISR ability) of UE itself and network are preserved is inconsistent.
