Method of realizing GSM and CDMA network information intercommunication

Abstract

A method to realize signalling intercommunication between networks of GSM and CDMA first establishes network connection between homing location register CDMA-HLR in CDMA network and homing location register GSM-HLR in GSM network and keeps a. copy of contracting information for each of them in HLR of both parties separately for the User of mobile phone that supports both modes in order to use numbers of one mobile users, and further adds network data disposition to the other party in network node of the entire network and makes internal communication protocol between GSM-HLR and CDMA-HLR, when the User's mobilephone is at cross-bridge roaming. The method needs not to add any extra network entity for its execution except network gate equipment.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for realizing network signaling intercommunication between GSM (Global System for Mobile Communication) and CDMA (Code Division Multiple Access Mobile Communication System). Background technique [0002] The GSM network currently dominant in the mobile communication field is relatively independent from the emerging CDMA network, that is, GSM network users cannot enjoy the services provided by CDMA, and CDMA network users cannot enjoy the services provided by GSM. In order to reduce call blind spots, improve network utilization, and realize seamless roaming of mobile users between CDMA / GSM dual networks, it has become a task to be solved in the field of mobile communication. One of the necessary conditions for dual-network seamless roaming is that the mobile phone can support CDMA and GSM at the same time, and can choose CDMA or GSM function according to the current netw...

[0005] 2) The impact on the operating system is relatively large. Because the standard call procedures of GSM and CDMA are inconsistent, in order to realize dual-network roaming, it is required to adjust the existing GSM / CDMA standard protocol. The implementation is difficult, the cycle is long, and there are unstable factors also more;

[0006] 3) It is difficult to support non-basic services. Since the IIF solution uses signaling translation between the two networks, it is not difficult to support the most basic authentication services and voice services. However, the telecommunications market is constantly changing and increasing New services, such as intelligent services, data services, etc., have very different mechanisms in different networks. It is difficult for IIF to track and upgrade to achieve complete signaling conversion, which affects the dual-network compatibility of services;
