Background technology
In order to guarantee the competitiveness of third generation partner program (3GPP The 3rdGeneration Partnership Project) system in following 10 years down to the time more of a specified duration, the work of an access technology evolution is just carried out at the 3GPP organization internal.Particularly, in the 3GPP system, use group technology to need further to strengthen in order to strengthen the 3GPP system handles ability of the IP data service of growth fast.Most important several sections comprises in this class technology evolution: reduce time delay, Gao Su user data rate more, the reduction of the power system capacity of enhancing and coverage and operator's integral body cost.And the network configuration of evolution also is an important index for the backwards compatibility of existing network.
Several principles related to the present invention that the network architecture of evolution need satisfy are as follows:
At the initial phase of accessing terminal to network, basic IP connects and need set up in the network of evolution;
The network architecture of evolution must minimize the time delay of user data;
The definition of each functional module should be avoided the overlapping or repetition of function in the evolution network framework, to avoid unnecessary signaling interaction and time delay.
In the existing 3GPP system configuration, the structure of user data plane as shown in Figure 1.As can be seen from Figure 1, the transmission of user data need be passed through Gateway GPRS Support Node (GGSN Gateway GPRSSupport Node), Serving GPRS Support Node (SGSN Serve GPRS Support Node), UMTS Terrestrial radio access network (UTRAN UMTS Terrestrial Radio Access Network) ability incoming terminal, the time delay that is produced is considerably beyond the desired time delay of network of evolution like this, so be one of key point of network evolution for the simplification of original 3GPP network configuration.
In addition, in original 3GPP system, the activation of the attaching process of GPRS and block data protocol context (PDPPacket Data Protocol context) is two separating process.After start, terminal can be carried out a GPRS (GPRS General Packet Radio Service) attaching process, wherein mainly is an authentication process.Before activating PDP Context, there is not IP to connect and adhere to the back terminal.Have only when selected Network Access Point and by SGSN when GGSN initiates the PDP context activation request, terminal just can be provided an IP address and corresponding configuration parameters.It is elongated to cause the user to initiate professional time delay like this, and the requirement of this process and evolvement network obviously is not inconsistent, so the network configuration of evolution needs new register flow path to reach this needs.
As shown in Figure 2, it is current wireless evolution network structure schematic diagram, the core net of wireless evolution network mainly comprises Mobility Management Entity (MME Mobility Management Entity)/user data face entity (UPE User Plane Entity) as seen from the figure, three logic function modules of anchor point between connecting system (Inter AS Anchor InterAccess Systems Anchor), MME wherein is the mobile management module, be responsible for the mobile management of chain of command, comprise the management of user's context and mobile status, distributing user temporary identity sign, safety function etc., it is corresponding to the control plane part of current UMTS internal system SGSN; UPE is a user entity, is responsible for initiating paging for downlink data under the idle condition, and IP bearing parameter and the interior routing iinformation of network etc. are preserved in management, and it is for the datum plane part of current UMTS internal system SGSN and GGSN; Inter AS Anchor then serves as the user's face anchor point between different access systems.Interface between Inter ASAnchor and the MME/UPE is S5 in Fig. 2, does not define the protocol stack and the message format of this interface in current 3GPP SA2.
Handover procedure among the existing standard TR23.882 specifically may further comprise the steps as shown in Figure 3:
The source wireless access network of S01, current service (also claim the service wireless access network, unification of the present invention is called the source wireless access network) decision initialization switches in another Target Wireless Access Network.
The request that S02, the transmission of source wireless access network need be switched is to source MME/UPE (also claim serving MME/UPE, unification of the present invention is called source MME/UPE).

S04, target MME/UPE transmit the handover preparation request to the Target Wireless Access Network.
S05, Target Wireless Access Network are the reservation that terminal is carried out resource.
S06, Target Wireless Access Network return handover to target MME/UPE and prepare to confirm.
S07, target MME/UPE return handover to source MME/UPE and prepare to confirm, and the Care-of Address that terminal is new sends to source MME/UPE.
S08, source MME/UPE send to UE by the source wireless access network with new Care-of Address.
S09, UE send the request of transmitting grouping by the source wireless access network to source MME/UPE.
S010, set up the tunnel between source MME/UPE and the target MME/UPE, source MME/UPE is transmitted to target MME/UPE by the tunnel with data in buffer.
S011, source MME/UPE send handoff command to the source wireless access network.
S012, source wireless access network send handoff command to terminal.
S013, terminal set up and the radio bearer of new Access Network.Have only in terminal under the situation of a wave point, after this terminal will receive and send data by new wireless access network.
S014, UE carry out the transmitting-receiving of follow-up data bag by the tunnel between source MME/UPE and the target MME/UPE.
S015, UE initiate mobile IP login request by target MME/UPE to Inter AS Anchor, Inter AS Anchor is updated to the home address of a terminal and the binding relationship between the new Care-of Address after the HSS/AAA server carries out authentication and query key information, and returns the register requirement of mobile IP registration response expression receiving terminal to terminal by target MME/UPE.
S016, Target Wireless Access Network send the handover notice that finishes to target MME/UPE.
S017, target MME/UPE transmit the handover notice that finishes to source MME/UPE.
Resource between S018, source wireless access network and source MME/UPE discharges.
S019, source MME/UPE send the handover affirmation that finishes to target MME/UPE.
