Telephone service executing method and device of double-network double-standby terminal

Abstract

The invention discloses a telephone service executing method and a telephone service executing device of a double-network double-standby terminal. The double-network double-standby terminal comprises an application subsystem, a 3rd generation (3G) wireless communication subsystem, a 2nd generation (2G) wireless communication subsystem and an identification module, wherein an identification card is inserted into the identification module; when a user of the double-network double-standby terminal uses a voice telephone service, the application subsystem selects the 2G wireless communication subsystem, the 2G wireless communication subsystem uses information in the identification card and the voice telephone service is executed through a 2G network; and when the user of the double-network double-standby terminal uses a video telephone service, the application subsystem selects the 3G wireless communication subsystem, the 3G wireless communication subsystem uses information in the identification card and the video telephone service is executed through the 3G network. Due to the adoption of the method and the device, concurrence of a voice telephone and a video telephone can be realized under a single-card single-number double-network double-standby condition.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a device for a dual-network dual-standby terminal to perform telephone services. 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 ...
