BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a block diagram of a dual Modem architecture system in accordance with an embodiment of the present invention. 2 is a schematic diagram of an application module including a statistical sub-module according to an embodiment of the present invention. FIG. 3 is a schematic diagram of a shared memory mode according to an embodiment of the present invention.

Preferred embodiment of the invention As shown in FIG. 1 , a schematic diagram of a dual modem (Modem) (ie, two wireless communication modules) architecture for a 2G and 3G dual-network dual standby terminal includes an application module, a 3G wireless communication module, and a 2G wireless communication module, where The 3G wireless communication module is configured to perform a videophone service in a Packet Switching (PS) service and a Circuit Switching (CS) service, where the 2G wireless communication module is configured to perform a service other than a videophone service. CS business. In order to solve the above problem of severe power consumption, in the present invention, three strategies are used to reduce power consumption. Strategy 1: Optimal Search Network Policy When the dual network dual standby terminal is powered on, the application module first controls the 2G wireless communication module and the 3G wireless communication module to be turned on, and then controls the 3G wireless communication module to enter a sleep state. Moreover, preferably, after the 3G wireless communication module enters a sleep state, the network search policy is not executed or the search policy is not executed within a specific time before performing the video phone service in the PS service or the CS service. The specific time can be set to a longer time, so that the 2G wireless communication module carrying the CS service is in the default open state when the power is turned on, and the 3G wireless communication module carrying the PS service and the videophone service is turned on first but mandatory after being turned on. After entering the sleep state, the search policy is not executed before the PS service occurs, or the search policy is not executed for a long period of time; thus, most users have only one 2G wireless in common application scenarios (such as voice calls or short messages). The communication module is in the state of enabling the search policy, so that the terminal can reduce power consumption. In addition, when the dual-network dual-standby terminal performs the PS service or the videophone service in the CS service, the application module controls the 3G wireless communication module to switch from the sleep state to the working state, and performs a fast network search policy; The application module controls the 2G wireless communication module to enter a sleep state and executes a search strategy. After the 3G wireless communication module switches from the sleep state to the working state, if no data interaction occurs within a certain time, the application module controls the 3G wireless communication module to enter a sleep state. This can further help reduce power consumption. Strategy 2: Turn the policy of the 3G wireless communication module on or off. The application module counts the usage frequency of the PS service and the videophone service, according to the statistics. Use the frequency control 3G wireless communication module to turn it on or off. As shown in FIG. 2, the application module adds a statistical sub-module, which uses a time domain as a statistical period to count the frequency of use of the PS service and the videophone service, where the time domain includes a daytime domain and a nighttime domain. If the dual-network dual-standby terminal is powered on, the frequency of use of the PS service and the videophone service is less than or equal to the first threshold in the entire daytime domain, or the frequency of use of the PS service and the videophone service throughout the nighttime domain. If the degree is less than or equal to the second threshold, the 3G wireless communication module is turned off at the beginning of the next time domain. If the dual-network dual-standby terminal is in the power-on state, the frequency of use of the PS service and the videophone service is greater than the first threshold in the entire daytime domain, or the frequency of use of the PS service and the videophone service in the entire nighttime domain. If it is greater than the second threshold, the 3G wireless communication module is turned on at the beginning of the next time domain. If the terminal switches from the power-on state to the power-off state during the statistical period, the statistics sub-module discards the used usage frequency data. Strategy 3: Applying a shared memory mode, the application module mounts flash memory (FLASH) and double rate synchronous dynamic random access memory (DDR), and the 3G wireless communication module and the 2G wireless communication module only hang Loading a flash memory; the 3G wireless communication module and the 2G wireless communication module share the DDR mounted by the application module with the application module. The DDR mounted by the application module includes three areas, namely: memory shared by the application module and the 3G wireless communication module, memory shared by the application module and the 2G wireless communication module, and memory occupied by the application module alone. Direct memory access is not available between the 2G wireless communication module and the 3G wireless communication module.

The 3G wireless communication module and the 2G wireless communication module do not need to mount the DDR. Therefore, when the terminal using the strategy is in the working state or the standby state, the SDRAM (ie, DDR) self-refresh power consumption will be greatly reduced to achieve the purpose of reducing power consumption. The invention is further described below in a specific application example. In this example, the hardware solution that the terminal can use is:

The AP (application) module uses Marvell's TAVOR PXA935A platform, and the 2G wireless communication module (which can be GSM/Enhanced Data Rate for GSM Evolution (EDGE) wireless communication module) uses ADI's TTPCOM platform. 3G wireless communication module (which can be TD-SCDMA/High Speed Downlink Packet Access (HSDPA) wireless communication module) uses LeadCore's A2000+H platform. The AP application module is responsible for implementing an application interface, an application service, audio and video codec, and interacting with a wireless communication module; the 2G wireless communication module carries a CS service other than a videophone, such as a voice call or a short message service (hereinafter referred to as CS). 3) The wireless communication module carries PS data services, such as surfing the Internet, and videophone services in the CS service (hereinafter referred to as PS services). A User Identity Module (UIM) or a Subscriber Identity Module (SIM) card module (ie, an identity module) is connected to a 2G wireless communication module and/or a 3G wireless communication module, and the UIM or the module is inserted in the module. SIM card. When the above terminal is powered on, the 2G wireless communication module carrying the CS service will be opened, and the optimized mature search strategy will be adopted; while the 3G wireless communication module carrying the PS service is turned on first but forced to enter the sleep state, and not The search policy is not executed before the PS data service occurs or the search policy is not executed for a long period of time. When the user uses the 2G CS service such as voice call or short message, if the 2G wireless communication module is in the sleep state, it will switch from the sleep state to the working state; while the 3G wireless communication module can still be in the sleep state and does not perform the search or the The search strategy is not implemented for a long period of time. When a user uses a 3G service such as surfing or videophone, the 2G wireless communication module usually sleeps but performs a search strategy, and the 3G wireless module switches from a sleep state to a working state, when a data interaction occurs. The 3G wireless communication module can be switched to the sleep state by quickly performing the search network strategy, and relying on the advantage of the 3G network bandwidth to quickly switch to the sleep state after the data interaction is completed quickly; and the data interaction does not occur within a certain period of time. It is estimated that the terminal designed with the above-mentioned search strategy will save about 300mW compared to the terminal using the traditional search strategy. The estimation formula is: Saving power consumption = Saving average search current * Average battery voltage The average battery voltage is equal to the full battery voltage of the terminal battery *80% for conversion. In this example, the AP application module adds a statistical sub-module for the user's usage habits, and the sub-module records the frequency of the user's use of the PS service to strategically control the opening/closing of the 3G wireless communication module. Assume that 24 hours are divided into two time domains: one time domain is from 8:00 to 22:59, which can be called "daytime domain"; another time domain is from 23:00 to 7:59, Call it the "night domain." If the frequency is measured every 30 minutes, the total frequency of the daytime domain is 30 times, and the total frequency of the nighttime domain is 18 times. Assume that the time domain is used as the statistical period. If the frequency of the PS data service used by the user in the entire daytime domain is less than or equal to 6 times, that is, the use frequency is less than or equal to 20%, or the user uses the PS data service throughout the night domain. If the frequency is less than or equal to 3 times, that is, the frequency of use is less than 18%, the policy of turning off the 3G wireless communication module will be enabled at the beginning of the next time domain; and then when the user needs to use the PS data service, the AP application sub-module performs the opening of the 3G. Wireless communication module. If the frequency of the PS data service used by the user in the entire daytime domain is greater than 6 times, that is, the frequency of use is greater than 20%; or the frequency of the PS data service used by the user in the entire nighttime domain is greater than 3 times, that is, the frequency of use is greater than 18%, then A 3G wireless communication module policy will not be enabled at the beginning of a time domain. If the terminal is switched from the power-on state to the power-off state during the statistics period, the statistics sub-module on the AP side discards the statistics of the PS data service usage frequency in the previous statistics period, and the terminal starts the optimal network search policy after the next power-on. The strategy of turning the 3G wireless communication module on or off is not applied. For a specific user group or a user group with a large number of 2G services and a small number of 3G services, the terminal applying the above strategy will reduce power consumption to a certain extent, and the power consumption saved needs to be operated according to different user groups and different time domains. Estimated factors such as PS business frequency. As shown in FIG. 3, in this example, data sharing between the shared memory mode 2G wireless communication module, the 3G wireless communication module, and the AP application module is performed. The usual design scheme is that the 2G wireless communication module needs to be mounted with FLASH (Flash) + Synchronous Dynamic Random Access Memory (SDRAM) carrier, the 3G wireless communication module needs to mount the FLASH+SDRAM carrier, and the AP application module needs to be mounted. FLASH+DDR carrier. When the terminal using the above design scheme is in working state or standby state The three SDRAMs and DDRs are still in a self-refresh hold state, and in the present invention, the AP application module is mounted with FLASH+DDR, and the 2G wireless communication module and the 3G wireless communication module only need to mount the FLASH; the AP application module mounts the DDR. Two separate memory spaces are divided into 2G wireless communication modules and 3G wireless communication modules. That is, the DDR is divided into three areas, namely: the memory DDR-CS shared by the application module and the 2G wireless communication module, the memory DDR-PS shared by the application module and the 3G wireless communication module, and the memory DDR-AP occupied by the application module alone. Since the self-refresh power consumption will be greatly reduced, the purpose of reducing power consumption is achieved. One of ordinary skill in the art will appreciate that all or a portion of the above steps may be performed by a program to instruct the associated hardware, such as a read only memory, a magnetic disk, or an optical disk. Optionally, all or part of the steps of the foregoing embodiments may also be implemented by using one or more integrated circuits. Accordingly, each module/unit in the foregoing embodiment may be implemented in the form of hardware, or may use software functions. The form of the module is implemented. The invention is not limited to any specific form of combination of hardware and software. 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 spirit and scope of the present invention are intended to be included within the scope of the present invention.
