Embodiment Construction

[0063] Next, we will further illustrate the method of the present invention by taking a GSM (Global System for Mobile communications) and PHS (Personal Handset System) dual-mode terminal as an example. Here, the GSM side and the PHS side may respectively use chips from different companies. The GSM module is the main control module, running the man-machine interface (MMI). The PHS module is a slave module.

[0064]Here we first define a set of I / O signals and interrupt signals, as shown in the following table:

[0065]

[0066] (wake / sleep signal

No)

The module initiates a request for communication

interrupt signal

model,

L stands for wake-up signal

3

PREADY

(communication allow / disable

stop signal)

Allow or prohibit communication on the P module side

4

GREADY

(communication allow / disable

stop signal)

Allow or prohibit communication on the G module side

Abstract

The invention discloses a terminal in dual modes, and control and comm. method for between inner chips. The mobile comm. terminal in dual modes includes first chip and second chip with serial port of comm. transceiver respectively. First chip is in use for first comm. mode and runs man-machine interface. Second chip is in use for second comm. mode. POWERON, IRQP, GREADY as output signals in first chip are realized by using GPIO. IRQG, PREADY, WORKINGDET are output signals. IRQG is realized by using falling edge to trigger interrupt. PREADY, WORKINGDET are realized by using GPIO. IRQG, PREADY, WORKINGDET as output signal in second chip are realized through GPIO. POWERON, IRQP, GREADY are as input signals. IRQP is realized by using falling edge to trigger interrupt.

Description

technical field [0001] The invention relates to the dual-mode terminal technology in the field of wireless communication, in particular to a method for controlling and communicating between modules of different standards in the dual-mode terminal. Background technique [0002] The diversification of existing mobile network technology standards brings the differentiation of user terminals. With the increase of multi-card users, users naturally have the need to increase the support capability of terminal standards to reduce the number of terminals. Multi-mode and multi-frequency have become the future mobile communication terminals. One of the directions of development. Dual-mode products with network switching function are very attractive. The purpose of developing this dual-mode terminal is to reduce the difficulty and cost for users to switch between different standard services by improving the standard support capability of mobile phones. [0003] From a technical point o...
