Interactive method of double mode mobile terminal and mobile network

Abstract

This invention discloses a method for interacting a double mode mobile terminal and a mobile network, which separates the functions of the circuit domain and the data domain and measures signals of a first and a second mobile communication systems separately, if signals of the first system does not cover so well as the second, then the services of the circuit domain and the data domain are received and sent by the network of the second system, if both of them cover well, then the circuit domain service is received and sent by the first system and the data domain service is sent and received by the second, if the signals of the first cover better than those of the second, then the services of the circuit and data domains are received and sent by the first one.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for interaction between a dual-mode mobile terminal and a mobile network. Background technique [0002] With the continuous development of mobile communication technology, mobile communication is currently in a transformation period from the second generation mobile communication system, such as the Global System for Mobile Communications (GSM), to the third generation mobile communication system that can provide higher rate services. [0003] In the third generation mobile communication system, Wideband Code Division Multiple Access (WCDMA) technology is one of the mainstream technologies. Moreover, with the continuous development of WCDMA technology and the continuous expansion of WCDMA network scale, various high-speed data services and other special services that WCDMA networks can provide attract more and more users, such as multimedia services, videophones, etc. ...

Problems solved by technology

[0008] Therefore, although the existing GSM / WCDMA dual-mode terminal can be applied to both the GSM network and the WCDMA network, but because the existing GSM / WCDMA dual-mode terminal cannot use the GSM network and the WCDMA network at the same time, the user cannot simultaneously Obtain the service of GSM network and WCDMA network

When the GSM / WCDMA dual-mode terminal resides on the GSM network and the user needs high-speed data services, since GSM cannot support high-speed data services, the GSM network must first automatically or manually migrate the user's mobile terminal to the WCDMA network , and then high-speed data services can be performed, which will increase the access delay of data services

When the GSM / WCDMA dual-mode terminal resides in the WCDMA network and the user needs to perform ordinary voice services, under normal circumstances, according to the operator's operating procedures, the WCDMA network needs to first switch the ordinary voice services through the handover process between systems. to the GSM network, and then the GSM network bears the corresponding ordinary voice services. However, because the success rate of inter-system switching is not very ideal, it will not only increase the call drop rate of voice services when using the existing dual-mode mobile phones, And it will cause the access delay of the voice service
