Mobile management method in gradual network

Abstract

This invention discloses a mobile management method in a radio evolution network including: dividing a mobile communication network into several equivalent route regions and broadcasting RAI in the regions, a UE receives the RAI and compares the received RAI with RAI list stored in the UE, when there is not RAI same to the received one in the RAI list, then it sends an updata request of RA, the network side responds the request of the RA and operates interactively with the UE to finish the update process with the UE.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a mobile management method in the mobile communication evolution network. Background technique [0002] Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System), as a complete 3G mobile communication technology standard, includes a series of technical specifications and interface protocols such as CDMA access network and packetized core network, and has further become a global standard formulated by the International Organization for Standardization 3GPP. One of the 3G standards. UMTS system is the third generation mobile communication system using WCDMA air interface technology. The UMTS system adopts a structure similar to that of the second-generation mobile communication system, including a radio access network (RAN, Radio Access Network) and a core network (CN, Core Network), where the radio access network is used to handle ...

Problems solved by technology

[0023] The disadvantage of this technical solution is that since the coverage of E-UTRA cells in the early stage of network construction of the evolved network is relatively small, mainly there are a large number of hotspots in the coverage area of ​​the 2G / 3G network, so the structure of the network is a large 2G / 3G network. There are a large number of evolved network TA areas in the 3G RA area

According to the requirements of restriction signaling, this "RAI pool" may contain a 2G / 3G RAI and many TAIs of evolved networks, so the amount of data is relatively large, which requires a certain amount of storage in the UE, and at the same time updates and network information in the routing area The signaling length during the attachment process will also increase significantly; in addition, this solution also requires changing the routing area update and network attachment signaling of the existing 2G / 3G network, so that the existing network needs to be upgraded in this regard. Compatibility with original 2G / 3G terminals must be considered, which brings certain complexity
