Embodiment Construction

[0119] First of all, it needs to be explained that in the present invention, the ERS and E-NodeB in the two architectures mentioned in the background technology are collectively referred to as base stations, and the IAGW and Access GW are collectively referred to as gateways. As described in the background technology, the base station has the RNC function, and the gateway It has GGSN and some SGSN functions. Of course, the solution of the present invention is also applicable to other similar architectures.

[0120] The solution of the present invention is mainly to have a control plane and a user plane protocol stack in the base station and a gateway respectively, and a cache module is provided in the user plane protocol stack of the gateway. Based on this setting, the architecture diagram of the solution of the present invention is shown in FIG. 12 .

[0121] Based on the above settings, the gateway is used to cache the data to be delivered through the buffer module after re...

Abstract

This invention discloses one method to realize area switching, which comprises the following steps: setting control panel and user panel agreement in base station and network gate; after receiving message, network gate processes buffer on sent data for materials preparation by aim base station; aim base station preserves materials to establish new user interface and establishing materials to fulfill UE area switching and the gate execution path and sending the data to aim station for information transmission between aim base station and UE.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, more specifically to a method for realizing handover between cells in the third generation mobile communication system (3GPP). Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a 3GPP system that adopts Wideband Code Division Multiple Access (WCDMA) air interface technology, and the UMTS system is usually also referred to as a WCDMA communication system. The UMTS system adopts a structure similar to that of the second generation mobile communication system, and the UMTS system also includes a radio access network (RAN, Radio Access Network) and a core network (CN, Core Network). Among them, RAN is used to handle all wireless-related functions, and RAN is usually called Terrestrial Radio Access Network (UTRAN); CN handles all voice calls and data connections in the UMTS system, and realizes switching and routing with external networks Func...
