Problems solved by technology

The 3G network can be compatible with the base station subsystem (BSS, Base Station System) of 2G, but in the long-term evolution project / system architecture evolution (LTE / SAE, Long Time Evolution / System Architecture Evolution) network, the general mobile of 3G is not considered Communication system Terrestrial Radio Access Network (UTRAN, Universal Mobile Telecommunications System Territorial RadioAccess Network) for compatibility, such as figure 1 shown
Therefore, it will be difficult to introduce the S1 interface of LTE / SAE through the 3G access network UTRAN

Abstract

The invention discloses a method for managing a position based on unifying an Iu-PS interface of a 3G network to an S1 interface of an LTE / SAE network. After receiving an attachment request message or a routing area updating request, an RNC replaces an RAI in which a UE currently exists with a TAI; and the RNC transmits the attachment request message or the routing area updating request comprising a TAI identifier to an MME, and the MME determines whether the network is a UTRAN network or an LTE network and carries out corresponding treatment. The invention can introduce the S1 interface of the SAE network through the UTRAN of the 3G network so as to further introduce some characteristics of the SAE network, therefore, the performance of the original 3G network is improved and the SAE network is caused to be compatible with the UTRAN of the 3G network so as to improve the evolution and integration of networks. In addition, the invention also discloses a radio access network controller, a mobile management entity and a system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a location management method, device and system based on an S1 unified interface. Background technique [0002] The development of mobile communication has formed a variety of wireless communication systems, such as the second generation mobile communication system (2G): Global System for Mobile Communication (GSM, Global System for Mobile Communication), General Packet Radio System (GPRS, General Packet Radio System), Enhanced data rate GSM service (EDGE, Enhanced Data rates for GSM service), code division multiple access (CDMA, Code Division Multiple Access); third generation mobile communication system (3G): unified mobile communication system (UMTS, Universal Mobile Telecommunications System, Also known as Wideband Code Division Multiple Access (WCDMA, Wideband CDMA)), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, TimeDivision-Synchronous C...
