Problems solved by technology

Due to the difference of the network, it will lead to continuous network reselection and residency
Not only consumes power, but also easily causes problems such as dropped calls during reselection;
[0013] 3. TD-SCDMA&GSM dual-card dual-mode dual-standby terminal: Although it can solve the above 1 and 2 problems, it must require customers to have two cards, which is very inconvenient for most single-card users

Embodiment Construction

[0046] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0048] The first embodiment of the present invention relates to a single-card dual-mode terminal. In this embodiment, the two network modes supported by the single-card dual-mode terminal are TD-SCDMA and GSM respectively, and TD-SCDMA is called the first network mode, and GSM is called the second network mode.

Abstract

The invention relates to the field of communication, in particular to a single-card dual-mode terminal and a communication method thereof. In the invention, services in a first network mode and services in a second network mode are respectively dispatched and processed through a main control module and a slave module, and the main control module also takes the action of a passage among the slave module, an SIM (Subscriber Identity Module)/USIM (Universal Subscriber Identity Module) card and peripheral devices. Accordingly, the dual-standby function can be realized by simultaneously residing one SIM card or USIM card in two different network modes so as to realize a single-card dual-mode and dual-standby terminal. The invention not only avoids the load of a single-card user for additionally purchasing other cards, but also can likewise realize the concurrency of a CS (Circuit Switch) service and a PS (Postscript Switch) service through the single SIM/USIM card. In addition, the whole power consumption is smaller than that of a traditional dual-card dual-mode and dual-standby terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to the dual-mode terminal technology in the communication field. Background technique [0002] With the continuous development of communication technology, various types of wireless communication systems have appeared, such as Global System for Mobile communication (Global System for Mobile communication, referred to as "GSM"), Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, referred to as " WCDMA"), Time Division Synchronous Code Division Multiple Access (TD-SCDMA for short), Worldwide Interoperability for Microwave Access (WiMAX for short), Long Term Evolution (LongTerm Evolution, short for "LTE") and so on. [0003] Under the current network conditions of China Mobile (TD-SCDMA network and GSM network coexist), the wireless terminals of existing China Mobile users have the following three forms: [0004] 1. GSM single-card single-mode single-standby, th...
