Communication terminal, communication subsystem, application subsystem and multimode communication method

Abstract

The invention provides a communication terminal, a communication subsystem, an application subsystem and a multimode communication method, relating to the communication field. The communication terminal comprises the communication subsystem and is used for converting the received radio frequency signals of a preset system type network into application data and converting the application data into the radio frequency signals of the preset system type network. The communication subsystem comprises a communication subsystem external interface. The application subsystem comprises an application subsystem external interface and is connected with the communication subsystem external interface through the application subsystem external interface, and the application subsystem is used for receiving user input by an input output device, processing the user input into the application data and then transmitting the application data to the communication subsystem, receiving the application data from the communication subsystem and processing the application data and then outputting the processed application data by the input output device. The application subsystem external interface and the communication subsystem external interface are in a separable coupling relationship. The invention breaks through the barrier that various communication systems can not mutually operate.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication terminal, a communication subsystem, an application subsystem and a multi-mode communication method. Background technique [0002] With the rapid development of electronic technology, application terminals such as PDA (Personal Digital Assistant, personal digital assistant), MP4 (Moving Picture Experts Group-4, portable media player) are increasingly abundant. Handheld application terminals have evolved from simply meeting single application requirements to meeting comprehensive requirements. Products that combine application terminals with communication modules are also gradually entering the market. More and more application terminals have added communication functions, such as the addition of WiFi (wireless fidelity, wireless compatibility certification) functions to PSP (Playstation Portable, portable handsets). And many multimedia application terminals that integra...

Problems solved by technology

Since the communication standards cannot be interoperable, barriers have been formed, which limits the user's choice of operator services

[0005] Although there are mobile terminals supporting two or more standards in the prior art, such mobile terminals usually include one master standard, the others are slave standards, and the mobile terminal and the communication module of the master standard are in a tightly coupled relationship. Limits the freedom of user choice and increases the user's cost of use
