Description
Technical field
The present invention relates to the communications field, relate in particular to the registration of different access technologies.
Background technology
In order to strengthen the competitiveness of future network, 3GPP is just putting forth effort on a kind of research of brand-new evolution network framework, its research direction comprises two kinds of situations: System Architecture Evolution (System ArchitectureEvolution, SAE) and the Long Term Evolution of Access Network (Long-Term Evolution, LTE).Its content comprises the Access Network of evolution and the packet core network of evolution.The Access Network of wherein said evolution is called UMTS Terrestrial radio access network (the Evolved UMTS Territorial Radio AccessNetwork of evolution, E-UTRAN), the framework of the packet core network of described evolution comprises following three logical functional entities as shown in Figure 1:
1, Mobility Management Entity (Mobility Management Entity, MME), be used for being 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/UMTS internal system SGSN.
2, user entity (User Plane Entity, UPE), be used for being 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 GGSN.
3, the user's face anchor point between the different access systems (Inter Access System Anchor, Inter AS Anchor) is used to serve as the user's face anchor point between different access systems.
Relevant with above-mentioned logical functional entity in addition network element also have the "Policy and Charging Rules Function entity (Policy and Charging Rule Function, PCRF) and home network server (HomeSubscriber Server, HSS).Wherein, described PCRF is used for implementation strategy control decision and flow based charging controlled function.Described HSS is used for storing user subscription information.
3GPP is after introducing 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 between these technology the signaling message of wireless access under idle condition, some solutions have been proposed at present:
First kind of solution is based on as shown in Figure 2 the network architecture and realizes that UE reduces the process of relevant signaling message when mobile in different access networks.Its main thought is: user data is kept among the SGSN of Pre-SAE network, when the user is registered to MME/UPE in the SAE/LTE network, MME/UPE in the described SAE/LTE network distributes Temporary Mobile Subscriber Identifier (Temporary MobileSubscriber Identity, TMSI) and tracking area (Tracking Area, TA) give user UE, equally, when the user is registered to SGSN among the Pre-SAE, SGSN among the described Pre-SAE distributes Temporary Mobile Subscriber Identifier (Temporary Mobile Subscriber Identity, TMSI) and (Routing Area RA) gives UE in the route district.When UE moves around in the RA of the TA of SAE and Pre-SAE like this, no longer include new Routing Area Update, thereby saved a part of signaling.
Second kind of solution is based on as shown in Figure 3 the network architecture and realizes that UE reduces the process of relevant signaling message when mobile in different access networks.Its main thought is: user data is kept among the MME/UPE of SAE/LTE network, and when the user was registered to MME/UPE in the SAE/LTE network, the MME/UPE in the SAE/LTE network distributed its TMSI separately, TA, RA to UE; Under the optional situation, when the user was registered to SGSN among the Pre-SAE, the TMSI that also can reallocate of the SGSN among the described Pre-SAE gave UE.When the user moves around under the RA of the TA of SAE/LTE and Pre-SAE like this, no longer include new Routing Area Update, thereby save a part of signaling.
The third solution is: when the user be registered in the SAE/LTE network and the Pre-SAE network in the time, described 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 does not need extra Routing Area Update signaling when mobile in these equal-cost route districts like this, thereby saves a part of signaling.
All relate to the process that UE is registered to two kinds of different Access Networks in above-mentioned solution, the prior art relevant with the present invention provided the idiographic flow that UE registers in Pre-SAE network and SAE network, and as shown in Figure 4, it comprises the steps:
Step 13, the MME/UPE among the SAE sends registration and accepts message to UE.
