Method for logging mobile terminal in dual modes, and mobile communication network

Abstract

The invention is used for implementing the registration of a dual-mode terminal from the packet switched (PS) domain to the circuit switched (CS) domain. In the invention, a corresponding relationship between two user's IDs in two domains, both belong to one dual-mode terminal, is built in database; when the mobile terminal registers at PS domain, NeDS gets its user's ID in CS domain by enquiring the corresponding relationship, and according to its user's ID sends the registration information to the HLR in CS domain; said HLR labels the mobile terminal as 'in PS domain'. Said database can be set in NeDS, or in an independent apparatus, or in the HSS and ENUM server. If the NeDS enquiries the corresponding relation ship at the HSS and ENUM server, then it saves the enquiry result in local, and at next enquiry, firstly searches the corresponding relationship saved in local.

Description

technical field [0001] The invention relates to the third-generation mobile communication technology, in particular to a registration method of a dual-mode mobile terminal. Background technique [0002] With the rapid development of communication technology, people's expectations and requirements for communication are getting higher and higher. The third generation mobile communication (The Third Generation, referred to as "3G") system has great characteristics such as high bandwidth, multiple services, and high quality. Attract the consumer market. [0003] The 3G system includes a radio access network (Radio Access Network, "RAN" for short) and a core network (Core Network, "CN" for short). Among them, RAN handles all wireless-related functions; while CN handles all voice calls and data connections in the 3G system, and realizes switching and routing functions with external networks. [0004] The CN is logically divided into a circuit switched domain (Circuit Switched Do...

AI Technical Summary

Problems solved by technology

[0021] In practical application, the above scheme has the following problems: the registration of dual-mode mobile terminals to the packet domain is relatively limited

However, this problem is not explained in the current 3GPP2 standard. For example, in the ENUM technology CDMA MAP protocol, the two messages of the location registration request and the deregistration request will not have a mobile directory number (Mobile Directory Number) in E.164 format. Number, referred to as "MDN"), and only the user IMSI number in E.212 format
