Embodiment Construction

[0026] In order to express the purpose, technical solutions and advantages of the embodiments of the present invention more clearly, the technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with specific embodiments and drawings.

[0027] In the embodiment of the present invention, a new functional entity Pre-Handover Entity (PHE) is introduced under the existing 3GPP network and WiMAX network integration framework. The specific network structure is as follows: figure 2 As shown, the pre-handover entity PHE is connected to the terminal, the 3GPP network and the WiMAX network in a communicable manner, for example, the pre-handover entity PHE can be connected to the SGSN or MME entity in the 3GPP network in a communicable manner, It is connected to the ASN-GW in the WiMAX network in a communicable manner. In the embodiment of the present invention, the ASN-GW connected to the pre-handover entity PHE is called t...

Abstract

The embodiment of the invention provides an intersystem transfer method, an intersystem transfer device and communications systems, and more particularly the intersystem transfer method comprising thefollowing steps: a pre-transfer substantiality PHE is arranged in a system in advance, the PHE can communicate with a terminal, a 3GPP network and a WiMAX network, the PHE receives a request from theterminal and executes a pre-registration from the terminal to the WiMAX network, and when pre-registration is completed, the PHE receives a transfer request from the terminal and transfers the terminal to the WiMAX network. The substantiality PHE is introduced into an integrated frame of the 3GPP network and the WiMAX network, and thereby when the terminal probably needs to be transferred from the 3GPP network to the WiMAX network, the terminal firstly pre-registers in the WiMAX network by the PHE and can be transferred from the 3GPP network to the WiMAX network by sending a transferring request to the PHE.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, device and communication system for switching between systems. Background technique [0002] WiMAX (Worldwide Interoperability for Microwave Access), the Chinese full name is Worldwide Access Microwave Interoperability, is a wireless metropolitan area network technology based on the IEEE 802.16 standard. The WiMAX network is mainly composed of three parts, namely the terminal (MS / SS: Mobile Station / SubscriberStation), the access service network (ASN: Access Service Network) including the base station (BS: BaseStation) and the access service network gateway (ASN GW: Access Service Network-Gate Way) and Connectivity Service Network (CSN: Connectivity Service Network) include logical entities such as prepayment server (PPS: PrepayServer), authentication, authorization and accounting server (AAA Server: Authentication AuthorizationAccounting Server). Such as figure 1 As...
