Problems solved by technology

Both ends of each signal line need to be connected to the I / O ports of module one and module two, but for the I / O ports of the chip, it is very limited, so this solution takes up too much space. The I / O port uses too many signal lines, which wastes system resources and increases costs

Embodiment Construction

[0038] First, the principle of the present invention is briefly explained. In the present invention, two signal lines are set between two modules that need to wake up each other, and a hardware interrupt is adopted to realize interrupt wake-up and state detection of the other side through the two signal lines.

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] refer to figure 1 , shows a schematic structural diagram of an embodiment of a multi-mode terminal in the present invention. As shown in the figure, the multi-mode terminal includes a GSM module 10 and a CDMA module 20, both of which are independent communication modules.

[0041] The serial bus UART is connected between the GSM module 10 and the CDMA module 20, and the GPIO3 of the GSM module 10 is connected with the GPIO13 of the CDMA module 20 as a power supply port; the reset signal of the GSM module 10 is passed through its GPIO4 Send to the GP...

Abstract

The invention discloses an activation method of mobile terminal modules, which consists of the following steps: a: a first module sends interrupt pulse or interrupt level to a second module; b after receiving the interrupt pulse or the interrupt level, the second module checks and records the state of the first module and updates the state thereof according to the state. In the invention, becausethe hardware interrupts mode is adopted to activate the activated module; the situation that the transmission of AT command by serial ports for triggering interrupt tends to make transmission mistakes is avoided. The interrupt triggering of the invention is more stable. The invention also discloses a multi-mode terminal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for waking up between modules of a mobile terminal and a multi-mode terminal applying the method. Background technique [0002] At present, there are more and more dual-mode dual-standby mobile phones in the field of mobile communication technology, such as GSM and CDMA dual-mode dual standby, TD-SCDMA and CDMA dual-mode dual standby, CDMA and PHS dual-mode dual standby and In the near future, there will be dual-mode dual-standby of WCDMA and TD-SCDMA. Among so many dual-mode and dual-standby mobile phones, the single-mode and single-standby mobile phones of each standard are already very mature, so for dual-mode and dual-standby mobile phones, how to achieve communication reliability and how to achieve mutual wake-up more efficiently The mechanism becomes the key to the overall solution. [0003] In the prior art, for the wake-up method between two modules inside a...
