Communication method and communication device of double-network double-standby terminal

Abstract

The invention discloses a communication method and a communication device of a double-network double-standby terminal. The double-network double-standby terminal comprises an application module and a wireless communication subsystem, wherein the wireless communication subsystem comprises an identification module, an identification card is inserted into the identification module, and identification information for a 2G (The 2nd Generation Telecommunication) network and a 3G (The 3rd Generation Telecommunication) network is saved in the identification card. The communication method comprises the following steps of: when a user of the double-network double-standby terminal initiates a service, the application module is used for selecting networks according to the type of the service; the wireless communication subsystem is used for monitoring network signals; and when the selected network satisfies a signal strength condition, the wireless communication subsystem uses the information in the identification card to communicate through the selected network. The invention considers both 2G network CS circuit domain specialized skill and 3G network data specialized skill, reduces double-mode switching probability through the double-network double-standby technology and increases the user application feel of the terminal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for communication between terminals with dual networks and dual standby. Background technique [0002] With the gradual development of domestic 3G network construction, the three major mobile communication operators have officially entered the 3G era. However, due to the initial stage of the current 3G network construction and the next period of development, the coverage level of the 3G network has been continuously optimized and improved for more than ten years compared with the 2G network. All natural villages) or the depth of coverage (such as indoors, basements and subways, etc.), there is a big gap. Therefore, major operators have also taken the long-term coexistence of 2G and 3G dual networks as their operating goals and strategies. China Mobile even put forward the three-no principle of "do not change the card, do not change the number, and do not n...

Problems solved by technology

[0003] However, this strategy of "coexistence of 2 and 3G networks" and "customization of TD / GSM dual-mode single-standby terminals" has encountered difficulties in actual operation.

On the one hand, due to the existing "2, 3G dual-mode switching" strategy, mobile terminal reselection is frequent, power consumption is serious, calls are dropped, Internet access is disconnected, and even abnormal faults such as disconnection occur from time to time, and the user experience is poor ; On the other hand, because the coverage quality of the existing 3G network is far inferior to that of the GSM network, users have insufficient confidence in the TD network

Network problems lead to terminal dilemmas, which in turn magnify network problems
