Embodiment Construction

[0049]Since the combination of the 3GPP anchor point and the SAE anchor point is still under study, the SAE anchor point is used in the embodiment of the present invention to describe the functional entity that controls the mobility of different access systems; in addition, in the traditional 3GPP system, the packet data The gateway (PDG, Packet Data Gateway) is a functional entity defined in the I-WLAN system, which means that when the terminal accesses the packet service (PS, Packet Service) through the WLAN 3GPP IP access mode, it needs to access the external packet data network through the PDG (External Packet DataNetwork, EPDN, hereinafter referred to as the external network); the embodiment of the present invention defines that the gateway (GW, Gateway) is the gateway when the terminal accesses the PS service through the Non-3GPP system; because the positions of the PDG and the GW do not affect the terminal switching method Therefore, the location of the two entities PDG ...

Abstract

The invention discloses a method for switching between systems and a system, which is used for solving the problems that a terminal device can not access services when switching between a 3GPP evolution system and an interconnect wireless local system or a non 3GPP system. The method of the invention comprises steps: when a terminal device which does the grouping service through a first access system asks for accessing a second access system, providing IP address allocated during accessing the grouping service to the second access system; the second access system sends request messages, asks for establishing the connection of a anchor point and the second access system, provides marks of the IP address and the terminal device; according to marks of the IP address and the terminal device, the anchor point updates the route information of user interface corresponding to the terminal device, continues the grouping service with the terminal device through the second access system. The invention can guarantee continuity of the access service when the terminal device is switched between the systems.

Description

technical field [0001] The invention relates to a wireless evolution network in the technical field of mobile communication, in particular to a method and system for switching between systems. Background technique [0002] The existing wireless evolution system shown in Figure 1 includes an evolved radio access network (E-RAN, Evolved Radio Access Network), an evolved packet core network (EPC, Evolved Packet Core); the evolved packet core network EPC mainly includes a mobility management entity ( MME, Mobility Management Entity), User Plane Entity (UPE, User Plane Entity), different access system anchor points (IASA, Inter AccessSystems Anchor) three functional entities, among which, MME is responsible for the mobility management of the control plane, including user context and mobile state management, assigning user temporary identity, security functions, etc., which corresponds to the control plane part of the existing Universal Mobile Telecommunications System (UMTS, Univ...
