TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a switching device and method based on a multi-standard network. BACKGROUND Currently, terminals widely used in the world are mostly based on the second generation (2G) system network, for example, Global System for Mobile Communication (GSM) network and code division multiple access. The Code Division Multiple Access (CDMA) network is a digital system. The second-generation network has the characteristics of large capacity and wide coverage, but it is slow in data transmission. Compared with the existing second-generation technology, the third generation of mobile communication technology (The Third Generation, 3G) can increase system capacity, improve communication quality and data transmission rate. Although 3G technology has advantages in terms of fast transmission rate compared with 2G technology, the number of base stations is currently less than that of 2G, and the network coverage is small, which is caused by the lag of network construction. 2G mobile communication network Have a network with the most complete coverage in the world. Based on this, multi-standard terminals supporting 3G and 2G have emerged. For multi-standard terminals, it is inevitable to involve switching between different standard networks. For example, for the current dual-standard terminal, after the terminal is powered on, the two-standard network is always in working state, and the terminal monitors the networks of the two systems. The signal strength is switched according to the monitoring result, or it is switched according to the user's request. A terminal operating in the above manner consumes a large amount of power and occupies more network resources. SUMMARY OF THE INVENTION The present invention has been made in view of the problems in the prior art that support a multi-standard network terminal that consumes a large amount of power and occupies a large amount of network resources. To this end, the present invention aims to provide an improved handover based on a multi-standard network. The program to solve at least one of the above problems. According to an aspect of the present invention, a switching device based on a multi-standard network is provided, the device includes: a switching unit, configured to perform network standard switching on a terminal, and the method includes: loading a module, a driver for loading and/or activating a network system to be switched; a deactivation module for deactivating a network standard drive before switching; a monitoring unit for monitoring only the network before switching before the switching unit performs switching System, and only monitor the network system switched to after switching. According to another aspect of the present invention, a handover method based on a multi-standard network is provided. The method includes: monitoring a current network standard by a terminal; performing network switching of different standards according to a current network standard and a handover policy, where the foregoing handover The method includes: loading and/or activating a networked drive to which the switch is made, and performing a deactivation operation on the network standard drive before the switch; monitoring the switched network mode. With the technical solution provided by the present invention, the terminal only keeps one network system in an active state during the handover process, so that the terminal supporting the multi-standard network has only one network system in an active state, and only monitors the current network standard, and further It can save power and save network resources.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, and the features of the embodiments and the embodiments of the present invention may be combined with each other if they do not conflict. The multi-standard terminal mentioned below, also known as multi-mode terminal, can support GSM standard (including EGSM, GSM 850), General Packet Radio Service (GPRS), and enhanced data rate GSM. Enhanced Data Rate for GSM Evolution (referred to as EDGE), High Speed Downlink Packet Access (HSDPA), High Speed Downlink Packet Access (HSUPA), etc., CDMA system (including CDMA 20001X-EVDO, etc.), Wideband Code Division Multiple Access (WCDMA), Time Division - Synchronous Code Division Multiple Access (referred to as Time Division - Synchronous Code Division Multiple Access) It is a terminal of any two or more systems in the TD-SCDMA system, the Worldwide Interoperability for Microwave Access (WIMAX) system. The passing, transmitting, or transmitting of messages, information, arguments, parameters, data, etc., referred to hereinafter, may be implemented in any suitable manner including memory sharing, messaging, token passing, network transmission, and the like. Device Implementation As described above, in the current multi-standard terminal, the network system supported by it is monitored whether it is currently used or not. To this end, an embodiment of the present invention provides a terminal, where only one network standard is activated at any time, that is, only one network standard is monitored, and other network systems are in a low power or de-energized manner. (disable) state, there is no data interaction with the standard network in the low or disabled state. The terminal of the embodiment of the present invention is implemented by the following switching device. 1 is a block diagram showing the structure of a switching device according to a preferred embodiment of the present invention. The switching device preferably has an interactive interface function. As shown in FIG. 1, the switching device includes: an initializing unit 1 for performing an initializing operation; The unit 3 is configured to monitor only the current state of the terminal, that is, the current network standard of the terminal; the switching unit 5 is configured to perform a network standard switching operation on the terminal; and the interaction unit 7 is connected to each unit to perform Data interaction between the units is performed. For example, the interaction unit 7 can provide the data of the monitoring unit 3 to the switching unit 5 as a reference for switching, and can also receive data from the switching unit 5. Preferably, the interaction unit 7 may be a module having a User Interface (UI) function. The details of each of the above components are specifically described below. The initializing unit and the configuration unit are configured to load the preset network system when the terminal is powered on or powered on, so that the terminal is in the preset network standard. Preferably, the preset network standard can be supported by the terminal. The highest priority network standard among multiple network standards. At this time, the driver of the other system supported by the multi-standard terminal is not loaded. Therefore, when the terminal is powered on or powered on, it is equivalent to a single-standard terminal. at this time, The terminal only monitors the preset network standard. Preferably, as shown in FIG. 2, the switching device may be provided with a configuration unit 9, which may be connected to the initial unit 1 and the interaction unit 7 for configuring priority information of multiple network standards supported by the terminal. . Based on this, a handover policy can be set, and it is stipulated that, in the subsequent handover, the network system with a higher priority is preferentially switched. Of course, in the embodiment of the present invention, the traditional network may also be used to select the network to be switched by searching. In this way, the terminal can determine the network standard to be switched according to the preset priorities of the multiple network standards. The monitoring unit monitoring unit 3 is configured to monitor only the network system before the switching before the switching unit 5 performs the switching, and only monitor the switched network system after the switching unit 5 performs the switching, that is, only monitor the current network standard of the terminal. The monitoring unit 3 is preferably connected to the initialization unit 1. After the terminal is powered on or powered on, the preset network system is monitored (in this case, the preset network standard is the current network standard of the terminal), and the pre-allocation unit 7 will pre- The network system is connected to the switching unit 5; subsequently, the monitoring unit 3 monitors the network system to which the switching module 5 is switched (in this case, the switched network system is the current network standard of the terminal). As an implementation, the current network standard of the terminal can be displayed in the device manager in the registry. The monitoring unit is preferably presented in a thread and has the same life cycle as software having interactive interface functionality. In this way, the terminal can keep detecting only the current network standard to save power and save network resources. The switching unit switching unit 5 is configured to perform a network system switching operation on the terminal, and may perform switching according to a switching request submitted by the user via the interaction unit 7, that is, manually switching, or may switch based on the switching policy when the switching condition is met, that is, Automatically switch. For example, the switching condition here may be that the network condition such as the signal strength of the current network standard cannot meet the requirements of the terminal. For the case of the automatic switching, whether to perform the switching, as shown in FIG. 2, can be implemented by setting a decision module 52, which is used to determine whether to perform network standard switching according to the switching policy and the network standard before switching, as above. In the case that the monitoring unit 3 sends the preset network standard to the switching unit 5, the network system before the switching is the preset network standard. Preferably, as shown in FIG. 2, the switching unit 5 further includes a notification module 54 for notifying the interaction unit 7 of the network system to which the handover is made. After the switching network system is notified to the interaction unit 7, the monitoring unit 3 will automatically monitor the switched network system, but at this time, it is not necessary to perform Reported. When switching, if it is the initial switch after power-on, or if the network system that is switched to is used for the first time, it is necessary to load the driver of the network system switched to, and deactivate the drive of the network system before the switch; The drive to the network system that has been switched to has been loaded, then only the drive of the switched network mode is activated, without having to load again, and the drive of the network system before the switch is deactivated. In this way, even during the switching process, it is ensured that only the drive of the current network system is activated, i.e., that only the current network system is monitored by the monitoring unit 3, thereby saving power. As shown in FIG. 2, the above loading or activation process can be implemented by the loading module 51 of the switching unit, and the deactivation processing can be implemented by the deactivation module 53 of the switching unit 5. In the above preferred embodiment, the terminal only keeps one network standard in an active state during the handover process (by deactivating the network standard drive before the handover, and activating the networked drive of the handover), so that the multi-standard network can be supported. Only one network standard of the terminal is activated, that is, only the current network standard is monitored, thereby achieving the purpose of saving power and saving network resources. Taking the switching from the EVDO system to the WIMAX system as an example, the processing on the board side is as shown in FIG. 3. According to the switching command from the switching unit, the board side data line SWITCH is enabled to switch to the WIMAX device, for example, WIMAX. Firmware (WIMAX Firmware), before jt匕, cuts off the data line of the EVDO device (for example, EVDO Firmware), causing the EVDO system to enter the power-up mode. The management unit has different UI configuration modes for multi-standard terminals. For similar systems, you can use the unified style UI for configuration. For the system with large gap, for example, WIMAX and GSM are different. The style configuration mode, if the code is used for configuration modification, the workload is large. In view of this, preferably, as shown in FIG. 2, in order to reduce the cost and facilitate subsequent maintenance and use, the switching device according to the embodiment of the present invention further has a management unit 2 connected to the interaction unit 7 for managing the network standard. Configuration files, different stylized configuration operations, etc. Specifically, by using the management unit 2 to manage or load configuration files of different network standards (including network formats supported by the terminal and network formats not supported), subsequent configuration of different configuration styles can be realized by simply downloading a specific configuration file. There is no need to tamper with the terminal software code. By setting the management unit 2, the development cost caused by the differences in the UI styles of the various systems is avoided, and the robustness of the software can be improved. For example, in the scenario shown in FIG. 4, in terms of stylized configuration, network standards having similar configuration modes can be classified into one class, and A-type devices and A+1 system devices are classified into one class. The M system device and the M+1 system device are classified into one class. After that, for a certain network standard, the management unit 2 can dynamically read the configuration file according to the configuration file for stylized configuration. After the loading is completed, the device enters. The interaction unit (for example, the UI layer) makes the stylized configuration take effect. For the above described switching device, it can be integrated as a software in the data card of the terminal, or can be integrated in a terminal such as a mobile phone. Method Embodiment According to an embodiment of the present invention, a handover method based on a multi-standard network is further provided. The method can be implemented by using the switching device provided by the embodiment of the present invention, or can be implemented by using other suitable devices. Before describing the handover method according to an embodiment of the present invention, the initialization process of the multi-standard terminal will first be described. Preferably, the priority is set for multiple systems supported by the multi-standard terminal. When initializing, the terminal is set to the network system with the highest priority, which can be loaded by the network system with the highest priority during power-on or power-on. to realise. Since only the network system with the highest priority is driven in the terminal at this time, the terminal at this time can be regarded as a single-standard terminal. After the terminal is powered on, the terminal status is monitored in real time, that is, the current network standard of the terminal. During the handover process, according to the current network standard and the handover policy, network switching of different standards is performed, specifically, by loading or activating the network mode driver that is switched to, and deactivating the network standard driver before the handover. (disable) operation to achieve switching. The triggering condition for performing the handover may be a user request, that is, manual switching, or the current network standard cannot satisfy the terminal requirement, that is, automatic switching. Through the above activation and deactivation operations, only the driver of the current network standard can be activated, that is, only data interaction with the current network standard network. In this way, the subsequent real-time monitoring is actually only a monitoring of a network standard, and the power can be saved compared to the monitoring of all the systems supported by the terminal in the prior art. It should be noted that the handover policy herein may be: preferentially selecting a network system with a high priority to perform handover. By performing initialization and switching operations based on the priority of the network, the switching time can be saved compared to the prior art method of first determining the signal strength of each network. The invention is further described below in connection with examples. FIG. 5 is a flow chart showing a handover procedure in accordance with an embodiment of the present invention, which is implemented by integrating software that functions as a switching device according to an embodiment of the present invention. 3, a process comprising: (1) automatic switching process: step S501, the UI module initialization (i.e., the above-described interaction unit) to complete the initial portion of the work ^ _J UI interface; step S502, registration of different formats Components, for example, device 1 component, device 2 component, ..., device N component; step 4 gathers S503, starts device listening thread (ie, calls the above monitoring unit), and is used for real-time monitoring of devices in the registry The current device displayed in the manager generates a monitoring message about the current network standard. In step S504, the main interface determines that the device standard switching needs to be performed according to the monitoring message. If there is a device mode switching, the process proceeds to step S508: determining the device mode currently switched to. Step S 509, dynamically stylizing the required system interface according to the current device system requirement, for example, the operation may be implemented by the management unit 2; when the program needs to be exited, the process proceeds to step S510, and the device monitoring thread is closed to ensure the The listening thread is the same as the software life cycle, and then proceeds to step S511 to exit the software.

(2) The manual switching process step 4 is S505, and the switching is performed in response to the switching request from the user; in step S506 and step S507, the switching function module (for example, the switching unit) is called to perform the switching, and if the switching is successful, the process proceeds to step S508, and the process is performed. Subsequent steps S509-S511. For the switching operation involved in the processing of FIG. 5, it can be implemented according to the flow shown in FIG. 6. Step S601, reading the current network standard from the listening thread, assuming J network standard; Step S602-Step S603, determining that the current switching needs to be performed Network standard, selected by the user, or when the current device is unavailable, or no network signal or signal can not meet the terminal requirements, according to the advance The set switching policy determines the network standard to be switched to, which is assumed to be the M network standard; in step S604, the relevant command is sent to the board side, so that the original network standard J enters the low power mode, and the GPIO falling edge is sent for switching, and the wakeup needs to be performed. Switching to the network system M; Step S605, after the handover is completed, the current device state can be read from the listening thread as the network standard M, indicating that the handover is successful. Taking the EVDO-WIMAX dual-standard data card as an example, in the above step S604, when it is necessary to switch from the EVDO system to the WIMAX system, the EVDO sends an AT command to put itself into the sleep mode (low power mode;), and sends an API command. Wake up the WIMAX system; when it is necessary to switch from the WIMAX system to the EVDO system, WIMAX sends an API command to put itself into sleep mode, and sends an AT command to wake up the EVDO system. For the method embodiments given above, it may be implemented by hardware, software, firmware, middleware, code, hardware description language, or a combination thereof. When implemented in software, firmware, middleware or code, program code or code segments for performing the necessary tasks may be stored in a machine readable medium, such as a storage medium. Based on this, in accordance with an embodiment of the present invention, there is also provided a computer readable medium carrying program or instruction code, which may cause a processor when the program or instruction code is called by a processor Some or all of the processes described in the foregoing method embodiments are performed to implement the switching based on the multi-standard network. This can be understood by referring to the foregoing method embodiments, and details are not described herein. According to the foregoing at least one technical solution provided by the embodiment of the present invention, the multi-standard network switching can be more conveniently implemented, which is more power-saving and faster than the prior art. In addition, by setting the management unit, the development and operation costs can be reduced. And can improve the user experience. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the scope of the present invention are intended to be included within the scope of the present invention.
