Description

Multi-standby mobile terminal and mode switching method and system thereof

The present invention relates to a multimode terminal, and more particularly to a multimode single standby mobile terminal and a mode switching method and system thereof. Background technique

With the continuous development of mobile communication technology and the continuous development of the third generation mobile communication system, various types of mobile terminal data cards have been generated according to the needs of operators and users, such as GSM (Global System for Mobile Communication). System) mode, PHS (Personal Handy Phone System) mode, CDMA (Code Division Multiple Access) mode, and CDMA1X-EVD0 (where lx-EV means: on the CDMA1X network standard) Evolution, the development of standards; DO refers to Data Only, that is, data; EV-DO technology refers to an effective enhancement to provide data services to CDMA1X networks), WCDMA (Wideband CDMA, Wideband Code Division Multiple Access) Mode and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) mode, WIMAX (World Interoperability for Microwave Access) mode, and so on. The GSM mode usually includes modes such as GPRS (General Packet Radio Service) and EDGE (Enhanced Data Rate for GSM Evolution).

Currently, the most widely used mobile terminals in the world are based on GSM networks and CDMA networks. These are second-generation mode networks, namely 2G networks. 2G network has the most complete network coverage in the world, has very mature standards, and has large capacity, wide coverage, stable call quality and appropriate standby time, which can meet certain voice and data communication characteristics. However, it is slow in data transmission and cannot meet the higher demands of current users.

A new generation of mobile communication systems represented by CDMA1X-EVDO, WCDMA mode, TD-SCDMA mode, WIMAX mode, etc., can greatly increase system capacity, improve communication quality, and data transmission rate. However, due to the immature standards of the new generation of mobile communication networks, there are shortcomings such as small network coverage, which poses challenges for further promotion and commercialization.

To this end, a multi-mode mobile terminal can be provided in combination with the advantages of both, the terminal can not only use the currently completed 2G network for ordinary voice and data service operations, but also can perform high-speed data transmission of 3G networks under environmental permit conditions.

In this way, the sub-device corresponding to the sub-mode of the mobile terminal is in a power-off state when not in operation, thereby saving energy.

FIG. 1 is a flowchart of a mode switching method of a multimode single standby mobile terminal according to an embodiment of the present invention. The mobile terminal includes a master device corresponding to the master mode and a child device corresponding to the slave mode, and completes a handover module, and the switch module may be implemented by a processor or the like of the mobile terminal. The process steps of the method are as follows:

In step S101, the switching module acquires the mode to be switched to.

The switching module is a mode that is selected to be switched when the device corresponding to the current mode is unavailable or the network signal quality of the current mode is poor, and the mode to be switched is triggered by the automatic mode switching; or the user according to his own The manual mode switch that needs to be performed selects the mode that is required to be switched to triggers the execution of the mode to which the acquisition is to be made.

In step S102, it is determined whether the mode to be switched is the master mode, and if the mode to be switched is the master mode, step S103 is performed, and if the mode to be switched is the slave mode, step S104 is performed.

In step S103, all the child devices are powered off and the master device is in the normal working mode.

In step S104, the master device is placed in a low power state, and only the pair of submodes switched to are connected. The power and data lines of the sub-devices that should be used.

The flow of the mode switching method of the detailed multi-mode single standby mobile terminal is described by taking a three-mode data card and a three-mode mobile phone as an example. FIG. 2 is a flowchart showing a mode manual switching method of a three-mode data card according to an embodiment of the present invention. The multimode data card is mainly composed of a WiMAX mode master device, an EVDO mode sub-device, and a WCDMA mode sub-device. The method flow specifically includes the following steps: In step S201, the current mode state of the data card is read from the device listening thread.

In order to continue to control the entire module, the master device is in a low-power mode state, and can actively wake up at any time;

In sub-step S2042, selecting the device to be switched to, there are two devices to be switched to at this time: the main device, other sub-devices;

The switching module acquires the mode to be switched to which the step S202 is selected, and selects the device corresponding to the mode to be switched to.

In sub-step S2043, the device to be switched to is a WiMAX master device, and the master device is in a low-power mode state at this time;

In sub-step S2044, the switch of the sub-module is controlled to disconnect the current EVDO sub-device data line, the control switch disconnects the power line connecting the sub-module, and the GPIO rising edge is sent to wake the main device from the low-power mode, so that the WiMAX main device can normal work;

In sub-step S2045, when the handover is successful, the current working device status is read from the device listening thread as a WiMAX master device;

In sub-step S2046, the device to be switched to is another child device (WCDMA child device), at which time the WiMAX master device is in the low power mode state, and the WCDMA child device is in the power-off mode; in sub-step S2047, the switch switch of the control sub-module is controlled. Disconnect the current working sub-device (EVDO sub-device) data line, connect the WCDMA sub-device data line to be switched to, wake up the device, and make the device in normal working state; In sub-step S2048, when the handover is successful, the current working device status is read from the device listening thread as a WCDMA child device.
