Abstract
Method for selecting supervisor node includes steps: logging on first access network, mobile terminal (MT) selects a service node, and the service node selects first supervisor node (FSN) as a support node for the MT; when moving to second access network (SAN), the MT sends register request message to SAN, and SAN selects second supervisor node (SSN) to carry out registering for the MT; through the register request message, SSN finds out the service node, and obtains information of FSN from the service node; SSN compares info of FSN with own info; if the compared result is identical, then registering the MT on FSN right along; if the compared result is not identical, then SSN redirects the register request of mobile terminal to FSN, and registering the MT on FSN right along. When there is no moving signal in SAE system and 3GPP system, the invention implements looking up correct MME/UPE.
Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of method of selecting management node.
Background technology
SAE (System Architecture Evolution, System Architecture Evolution) framework of system sees also Fig. 1, core net comprises SAE EPC (Evolved Packet Core, the packet-based core networks of evolution) and GPRS (General Packet Radio Service, GPRS) SGSN in the core net (Serving GPRS supporting node, GPRS service node); The connecting system that SAE EPC is connected to is Evolved RAN (RadioAccess Network, wireless access network), be called LTE (Long Term Evolution, Long Term Evolution) again, the connecting system that SGSN is connected to is UTRAN/GERAN, is commonly referred to as Pre-LTE.
SAE system hereinafter described is meant that wireless technology adopts LTE, and core net is connected to the network system of MME/UPE; Tradition 3GPP (3rd Generation PartnershipProject, third generation partner program) system refers to wireless technology and adopts UTRAN/GERAN, and core net is connected to the network system of SGSN.
Each network element is defined as follows among the figure:
SGSN:2G/3G network packet domain-functionalities entity, be responsible for mobile management, session management, forwarding user data package, storage UE (User Equipment, subscriber equipment) contextual information, produce temporary mark and it distributed to UE, and be responsible for the user is carried out authentication etc.
MME (Mobility Management Entity, the mobile management node): the chain of command functional entity, be in charge of and store the UE context (such as the UE/ user ID, mobility management states, user security parameters etc.), produce temporary mark and it is distributed to UE, when UE quarters at this tracing area or this network, be responsible for this user is carried out authentication.
UPE (User Plane Entity, user face nodes): the user plane functions entity, the user face data route is handled, termination is in the downlink data of the UE of idle state, when the downlink data that mails to UE arrives, initiate paging, the context of management and storage UE, this context comprise such as the parameter of IP bearer service or network internal routing iinformation etc.
3GPP Anchor: user's face anchor point, this anchor point are supported the user entity of the mobile management between SAE system and traditional 3GPP system.
SAE Anchor, the mobile management anchor point between multiple connecting system, this anchor point are the user plane functions entities of supporting the mobile management between the multiple connecting system of 3GPP (comprising SAE and traditional 3GPP) and non-3GPP definition.
(Routing Area is that the user moves freely and do not need a geographic area of its change in location of informing network in the traditional 3GPP system RA) in the route district.In the SAE system, and corresponding with the route district is tracking area (Tracking Area, TA).SAE system and traditional 3GPP system may overlap on geography covers, and the user can move around between SAE system and traditional 3GPP system.By normal flow process, when the route district of traditional 3GPP system moved to the tracking area of SAE system, the user answered initiating updating of tracking area, with its reposition of informing network; Otherwise, when the user when the SAE system moves to traditional 3GPP system, the user should initiate routing update, its change in location of informing network.
But, because network edge jitter, when the user was in the intersection of two networks (SAE system and traditional 3GPP system), user's little moving may cause that the user frequently switches between two systems, and this can cause the user frequently to initiate routing update/tracing section updating to network.The signaling that causes therefrom may be stopped up wireless channel.
When the SAE system design, for fear of this between new and old two systems during frequent the switching caused hand off signaling stop up wireless channel, SAE requires when the user is in Idle (free time) state, when the user moves around, reduce mutual with network between SAE system and traditional 3GPP system as far as possible.This specific character is called as no signaling and moves (Signaling Free) in SAE.But, an internal system, if the user is when current route district moves to another route district, or when the user when current tracking area moves to another tracking area, the user still needs to initiate routing update or tracing section updating flow process, with the variation of its position of informing network.
At present when the SAE system design, employing be that the modes of two registrations (Double Registration) realize not having signaling and move.The principle that realizes is that the user registers in SAE system and traditional 3GPP system respectively, when the user when system changes to the another one system, if in the purpose system, route district or tracking area and route district or the tracking area preserved in the past do not change, and terminal just need not be initiated route district or tracing section updating.The user must activate default PDP (Packet DataProtocol, packet data protocol) context after adhering to immediately in traditional 3GPP system, to set up default IP carrying.And this PDP activates the MME/UPE of this locality of selection as GGSN (Gateway GPRSSupport Node, gateway support node).In order to realize that not having signaling moves, the MME/UPE that UE registers in SAE must be identical with user selected MME/UPE when activating among the UMTS (Universal MobileTelecommunication System, universal mobile telecommunications system).
In traditional 3GPP system, register earlier with the user, and then in the SAE system, be registered as example:
The user starts shooting in traditional 3GPP coverage, selects a SGSN, is attached to traditional 3GPP system.In order to support that not having signaling moves, user's beard and hair plays PDP and activates, to set up a default IP carrying.When PDP activated, SGSN no longer was traditional GGSN for the GGSN that the user selects, but a local MME/UPE among the SAE EPC.When the user moves to the SAE coverage, the user finds that wireless access technology changes, user's initiating updating of tracking area, at this moment, wireless access system is necessary for the user when selecting it PDP activating in traditional 3GPP system, and selected MME/UPE only in this way can accomplish just that as the access node of its network side in the SAE system not having signaling moves.
But, because selected MME/UPE information when not having the user in the tracing section updating message that sends in the SAE system PDP activating in non-3 GPP system when the user register, selected MME/UPE was the problem of necessary solution when how wireless access system found PDP to activate for the user.Purpose of the present invention is exactly the pathfinding problem that solves this MME/UPE.To this problem, in the framework of SAE, also there is not satisfied solution at present.
