Problems solved by technology

In this way, data transmission can be realized at a faster rate when the amount of data is relatively small, but when the amount of data is relatively large, for example, when moving hundreds of short messages from the GSM card to the TD-SCDMA USIM card, the It will prompt the user to be busy and please wait on the AP side, and it will take a long time to move and complete the operation

Embodiment Construction

[0028] The present invention proposes an improved architecture of an intelligent dual-mode mobile phone. Aiming at the existing architecture, a Universal Asynchronous Receiver / Transmitter (UART, Universal Asynchronous Receiver / Transmitter) communication port and several universal input and output ports are connected between two wireless MODEMs. (General Purpose I / Oport, GPIO) pins establish a communication channel, so that there is a data channel and a control channel between two wireless MODEMs (UART is a physical communication channel, GPIO is a control channel); The corresponding AT command processing function is added to the MODEM (AT command is the command protocol for data communication between the AP and the wireless MODEM), and the AT command processing function is used to process the data processing between the two wireless MODEMs. The data processing is in the data channel carried out in.

Abstract

The invention discloses an intelligent dual-mode mobile phone which comprises a first wireless modem and a second wireless modem; a third communication channel is arranged between the first wireless modem and the second wireless modem; the third communication channel is provided with a control channel and a data channel which conducts the data processing through expanded modem instructions. The invention also discloses a method for the information transmission between the wireless modems of the intelligent dual-mode mobile phone. The intelligent dual-mode mobile phone and the information transmission method not only reduce the loading of an application processor (AP) processing the data of the two wireless MODEMs but also reasonably utilize the AP and the processors of the two wireless MODEMs, thereby improving the cooperation capacity of the processor.

Description

technical field [0001] The invention relates to a communication technology, in particular to an information transmission method between an intelligent dual-mode mobile phone and its wireless modem. Background technique [0002] Smartphones are the mainstream of mobile phone development in the future. At present, an important architecture of smart phones is composed of an application processor (AP) and a wireless modem (MODEM), while a dual-mode smart phone is composed of an application processor (AP) and two wireless MODEMs. [0003] Such as figure 1 As shown, it is a structure diagram of a smart dual-mode mobile phone in the prior art. In the current smart phone, the application processor (AP) uses the communication channel 1 and the wireless MODEM1 to perform communication and data interaction, and the application processor (AP) uses the Communication channel 2 communicates and exchanges data with wireless MODEM2, and there is a SEVER layer on the AP side to process data ...
