Description
Technical field
The present invention relates to the mobile communication technology field, especially relate to a kind of method, mobility management apparatus and relevant network element device thereof of realizing that bearer reconstruction is upright.
Background technology
3G (Third Generation) Moblie normal structure (3GPP) is being studied a kind of brand-new evolvement network in order to strengthen the competitiveness of future network, called after System Architecture Evolution (SAE, System ArchitectureEvolution) system.As shown in Figure 1, block architecture diagram for existing SAE system, the UMTS Terrestrial radio access network (EUTRAN, Evolved UMTS Terrestrial Radio Access Network) 10 that comprises evolution is used to realize all and evolvement network wireless access function associated; Mobility Management Entity (MME, Mobility Management Entity) 20 is responsible for the chain of command mobile management, comprises the management to user's context and mobile status, distributing user temporary identity sign etc.; Service system architecture evolution gateway (ServingSAE GW, Serving System Architecture Evolution Gateway) 30 is the user's face anchor points between the 3GPP connecting system, is responsible for stopping the interface of ETURAN 10; Packet data network System Architecture Evolution gateway (PDN SAE GW, Packet Data Network System Architecture EvolutionGateway) 40, it is the user's face anchor point between 3GPP connecting system and the non-3GPP connecting system, be responsible for the interface of termination and external packet data network (PDN, Packet Data Network); "Policy and Charging Rules Function entity (PCRF, Policy and Charging Rule Function) 50 is used for the control of deal with strategy control and flow based charging; Home subscriber server (HSS, Home Subscriber Server) 60 is used to store user's CAMEL-Subscription-Information.
Wherein existing SAE system architecture also is in the continuous evolution process, has defined three kinds of User Status in the SAE system: released state (LTE_DETACHED is called for short Detached) refers to the state when UE does not insert the SAE system; Idle condition (LTE_IDLE is called for short Idle) and state of activation (LTE_ACTIVE is called for short Active) refer to the state after UE inserts the SAE system; Wherein when the user is in the Idle state, evolution Access Network side is not for the user sets up radio bearer resources, and there is not user's context in evolution NodeB yet on (being called for short eNB), also do not have corresponding S1 interface signaling connection between core net and the Access Network; When the user is in the Active state, evolution Access Network side has been set up radio bearer resources for the user, the context that has the user on the eNB, and exist corresponding S1 interface signaling to connect between core net and the Access Network, the user is in that Active state following time can be carried out normal context data processing and signaling message is mutual.
As shown in Figure 2, for having the mutual conversion schematic diagram of user between Idle state and Active state in the SAE system now, when the signaling connection of S1 interface was released (S1 signaling connectionreleased), the user can switch to the Idle state from the Active state; When the signaling connection of S1 interface was established (S1 signaling connection established), the user can switch to the Active state from the Idle state.Wherein the signaling of S1 interface discharges and can be initiated by core net (CN), and when separating shutdown such as the user, the S1 interface signaling that MME can notify eNB to discharge the user connects; The signaling of S1 interface discharges also can be initiated by eNB, and in the use of monitoring and scheduling interface-free resources, when surveying less than user movable or out of touch, the S1 interface signaling that eNB can discharge the user connects such as eNB.In addition, the user initiates any signaling process, comprise and adhere to (Attach), tracing section updating (TAU, TrackingArea Update), initiate service request (Service Request), response paging and separation etc. to MME and all can trigger the signaling connection of setting up the S1 interface, thereby the user will enter the Active state, when discharged the connection of S1 interface signaling next time again, the user just can come back to the Idle state.
As shown in Figure 3, for having now in the SAE system, the user switches to the process chart of Active state by initiating Service Request from the Idle state, and processing procedure wherein is: UE sends service request (Service Request) message and gives MME (step 1); If MME accepts the service request that UE sends, MME will return professional (Service Accept) message of accepting and give UE (step 2); If the type of service of UE request is a signaling, then MME does not initiate the flow process of setting up of RAB, if the type of service of UE request is data, then MME sends RAB and sets up request (Radio AccessBearer Assignment Request) message and give eNB, sets up flow process (step 3) with what request eNB initiated RAB; ENB sends radio bearer foundation (Radio Bearer Setup) message and gives UE to set up radio bearer (step 4); UE returns radio bearer foundation and finishes (Radio Bearer Setup Complete) message to eNB (step 5); ENB returns RAB and sets up response (Radio Access BearerAssignment Response) message to MME (step 6); MME sends and revises bearer context request (Update Bearer Context Request) message to Serving SAE Gateway (step 7); Serving SAE Gateway returns something for repairs and changes bearer context response (Update Bearer Context Response) message to MME (step 8).The signaling that can set up the S1 interface by this process connects and radio bearer, therefore can make the user switch to the Active state from the Idle state.Said process is initiatively initiated service request by the user and is realized self switching to the Active state from the Idle state, network side also can pass through to user's distributing paging in addition, initiate service request with the indication user, thereby realize switching to the Active state from the Idle state.
Because the user is in Idle state following time, evolution Access Network side is not set up radio bearer resources for the user, and it also is d/d that the S1 interface signaling between Access Network and the core net connects, when being in user under the Idle state like this and will using related service, will to require network side the Active state procedure be that it rebuilds upright corresponding bearer resource switching to from the Idle state, as rebuild upright radio bearer, distribute idle wireless resource etc.Carrying generally is divided into assurance bit rate (GBR, Guaranteed Bit Rate) carrying and non-GBR carrying, wherein for the GBR carrying, needs network side to distribute proprietary Internet resources; For non-GBR carrying, do not need network side to distribute proprietary Internet resources, comprise default SAE carrying and signaling bear etc.
At present, the user is when the Idle state switches to the Active state, network side is only rebuild the bearing resource that the user need use usually, and do not rebuild other bearing resource, for example there are three carryings: carrying A, default SAE carrying, signaling bear wherein carries the video traffic that A is used to carry the user.When the user under being in the Idle state wants to use video traffic, UE will ask network side to rebuild upright carrying A for it, and network side only founds carrying A for the user rebuilds like this, and for default SAE carrying and signaling bear, will can not rebuild upright.If the user wants to continue to use the IMS business like this, will initiate the service request flow process once more and rebuild upright signaling bear for it with the request network side, could carry out the foundation of IMS operation flow based on rebuilding upright signaling bear, therefore will cause the setup delay of operation flow to increase.
