Method and device for dual-mode dual-standby terminal to implement communications

Abstract

The invention discloses a method and a device for a dual-mode dual-standby terminal to implement communications, wherein the method comprises the steps as follows: when a user of the dual-mode dual-standby terminal launches a packet service (PS), or a videophone service in a circuit service (CS), if a 3G (third-generation) network signal satisfies the condition of signal strengths, then the dual-mode dual-standby terminal selects a 3G network to implement communications; otherwise, the dual-mode dual-standby terminal selects a 2G (two-generation) network to implement communications; when the user of the dual-mode dual-standby terminal launches a CS service except the videophone service, and if the CS domain resources of the 2G network are saturated, then the dual-mode dual-standby terminal selects the 3G network to implement communications ; otherwise, the dual-mode dual-standby terminal selects the 2G network to implement communications. The invention can reduce and avoid the faults of a 2 / 3G dual-mode single-standby terminal like frequent network reselection, high power consumption, call drop, network fault caused by a `2 / 3G dual-mode switching` strategy, and improve the user experiences 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...

AI Technical Summary

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

[0004] It is also the user's distrust of the TD network and the status of TD terminals. On the one hand, the GSM network is overloaded, and a large amount of GSM resources are occupied by data services; on the other hand, the network utilization of TD is very low At the same level, network resources are seriously wasted, and the development of TD network is also severely restricted
