Description

TECHNICAL FIELD The present invention relates to the field of third generation mobile communication technologies, and in particular, to a method for implementing network switching by a TD/PHS dual mode mobile terminal. BACKGROUND OF THE INVENTION Currently, dual-mode mobile phones are nothing more than GPRS/GSM, CDMA/GSM and WCDMA/GSM. The implementation of dual-mode implementations varies from manufacturer to manufacturer, and the frequencies of the two modes in the dual-mode are separated. Farther, the mutual interference is low, so in this dual-mode mobile phone, a ^: is dual standby, both modes can be in standby mode, and one mode does not need to consider another mode when making a call. Radio frequency interference generated by it. If the frequencies of the two modes in the dual mode are relatively close, considering the radio frequency interference, if a dual standby solution is used, then in one mode of the dual mode, when the call is made in another mode, the radio interference of the other mode may cause the service to be impossible or The quality of the business has dropped significantly. For the former, the current mobile phones are generally dual-mode dual standby, while the latter is generally dual-mode single standby. If you need to make another mode call, you need to shut down and then boot into another mode. Considering that the frequency bands of each mode in the 3G frequency band are adjacent to each other, the 3G-based dual-mode mobile phone realizes the call in the dual-mode dual standby mode, which causes the service quality to deteriorate. If you adopt a dual-mode single-standby solution, you will not be able to experience the convenience of dual-mode phones for end users. Therefore, mobile phone manufacturers hope to achieve dual-standby mode in the case of two modes that may cause radio frequency interference. However, there is no ideal dual-mode dual-standby call solution. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a method for implementing network switching by a TD/PHS dual-mode mobile terminal, which can directly perform network switching, and does not need to be restarted after switching. In order to solve the above problems, the present invention provides a method for implementing network switching in a TD/PHS dual-mode mobile terminal. The TD/PHS dual-mode terminal is referred to as a dual-mode terminal, including a TD module and a PHS module, and the TD/PHS The dual mode terminal has a TD single standby state, a PHS single standby state, and a TD/PHS dual standby state, and the method includes the following steps.

(a) the dual mode terminal determines whether the current standby state is the target standby state selected by the user Same, if different, perform the next step;

(b) The dual-mode terminal determines whether it is necessary to disconnect the network connection of the TD or the PHS according to the target standby state selected by the user and the current standby state, and if so, disconnects the corresponding network connection, and closes the module and protocol of the corresponding standard. (c) The dual mode terminal determines whether it is necessary to turn on the network connection of the TD or the PHS according to the target standby state selected by the user and the current standby state, and if so, the TD or PHS module is turned on, and the corresponding network is searched for registration;

(d) Save the new standby status and adjust the functions and display information provided to the user according to the new standby status. Further, the user selects a target standby state through a mode switching menu of the human machine interface. Further, if the current standby state is TD single standby, and the target standby state is TD/PHS dual standby, the PHS module is turned on. If the target standby state is PHS single standby, the TD network is first disconnected, the TD module is turned off, and the PHS is turned on. Module; If the current standby state is PHS single standby, the target standby state is TD/PHS dual standby, then the TD module is turned on. If the target standby state is TD single standby, first disconnect the PHS network, close the PHS module, and then turn on the TD module. If the current standby state is TD/PHS dual standby, the target standby state is TD single standby or PHS single standby, then the PHS module or TD module is turned on. Further, in the step (b), if the TD module needs to be opened for network registration, if the registration fails but the registration does not time out, the registration is continued, and if the search is finished, the next step is performed. The proposed method provides an ideal solution for the implementation of dual-mode dual standby with close frequency points. It can be used in all two-mode dual-mode terminals that may cause interference, and is especially suitable for dual-mode mobile terminals in which TD-SCDMA is one of the systems. The method for implementing the network switching search network according to the present invention can prevent the service quality of the dual-mode dual-standby mobile phone from being degraded due to the radio frequency protection or the service cannot be realized when the dual-mode dual standby mobile phone performs the service, and the service cannot be realized at the same time. The radio frequency method avoids the problem of excessive waiting time for switching between modes, and effectively controls mode switching in various situations. It allows users to have dual-mode capabilities of dual-mode phones, as well as the convenience of dual-mode phones, improving the functionality and usability of dual-mode phones. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a system structural diagram of an embodiment of the present invention; FIG. 2 is a flowchart of a dual-mode terminal startup according to the embodiment; FIG. 3 is a flowchart of an MMI handover network. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. FIG. 1 is a system architecture diagram of the present embodiment. In the figure, the PHS module is an independent functional module that implements various functions of the PHS, and the DMC interacts with the PHS module through the AT command set. ARENA is the underlying platform that implements various business functions for TD. A dual-mode control module DMC (ZTE-BL dual-mode logic encapsulation layer in the figure) is introduced between the MMI (Man Machine Interface) and the dual-mode two protocol stack (PS). The logic control is stripped from the MMI, and the DMC interacts with the two protocol stacks. The MMI is only responsible for the task processing of the user logic, and the DMC is used for centralized control and management of the underlying information and upper layer messages, focusing on the dual-mode service. Logic, including mode switching, dual-mode service conflict handling, avoiding radio interference during calls, etc., which is beneficial to the platformization of dual-mode mobile phones. The IDLE module is a module for the upper layer MMI to centrally manage various platform messages. It transmits and receives different platform network side information and interacts with the DMC. The IDLE module also controls the management of each upper MMI function submodule. The IDLE module can enter each Function submodule. The MINIGUI/FW module is the framework foundation of the upper MMI, and implements the window style graphic menu of MMI. Take the TD/PHS dual-mode terminal as an example (of course, it can also be a TD/WCDMA or TD/CDMA dual-mode terminal, and the main module can be any one of the dual-modes), and the dual-mode mobile terminal realizes network switching search when the user starts up. The method of the network (see FIG. 2) includes the following steps: Step 210: Read the preset mode, perform corresponding search according to the mode status flag value, determine the search network type, if it is a TD single standby or TD/PHS dual standby execution step 220, if it is a PHS single standby step - step 230; the mode status flag values respectively indicate a TD single standby state, a PHS single standby state, and a TD/PHS dual standby state. After obtaining the mode status flag value, it can first detect whether the mobile phone password is correct, and if it is correct, perform corresponding search according to the mode status flag. In step 220, the TD module radio and the protocol stack are started, and the TD mode network search network is performed to find the registration to the TD network. When the MMI receives the TD module network search status, it determines whether the PHS search network needs to be performed. If yes, perform the steps. 230, otherwise the standby state is switched to TD standby, and the search process ends; if there is a problem with the TD's SIM card, it still enters the TD standby mode. At this time, only the emergency call of the TD can be dialed, and the SIM card is inserted at the same time. When the switching mode is TD/PHS dual standby, the TD module reports the TD network information such as network or no network or search network or emergency status, and the MMI judges the information. If it is the search network, the PHS registration is not performed, only The PHS network registration is not carried out in the search network. Since the TD/PHS dual-mode terminal uses the TD module as the main module, the TD network is searched first. For other TD mode dual-mode terminals, corresponding processing should be adopted according to whether the TD module is used as the main module. In step 230, the TD module radio and the protocol stack are started, and the PHS mode network search network is performed to find the registered PHS network. When the MMI receives the PHS module search network ending state, it is determined that the TD module is in the on state, and the standby state is switched. For TD/PHS dual standby, otherwise the standby state is switched to PHS single standby, and the search process ends. If there is a problem with the PIM card of the PHS, it still enters the PHS standby mode, but since the PHS does not have an emergency call, it cannot be dialed, and the PIM card is inserted at the same time. In the case of standby or no card, the user can enter the mode switching menu to switch the mode arbitrarily. For example, from TD/PHS dual standby to TD single standby, the PHS radio and protocol stack are turned off. If the TD single standby mode is PHS single standby, the TD radio frequency and protocol stack are first turned off, and then the PHS search network is started. Referring to FIG. 3, the switching process includes the following steps: Step 310, the user enters the mode switching menu, and selects the switched mode. Target standby state; Step 320, determining whether the current standby state is the same as the target standby state, if yes, ending, if not, in the next step; Step 330, determining whether to disconnect the PHS network connection, and if yes, performing the next step, otherwise Step 350: Step 340, disconnect the PHS network connection, close the PHS radio frequency module, the protocol stack; Step 350, determine whether to disconnect the TD network connection, and if yes, perform the next step, otherwise perform step 370; Step 360, disconnect TD network connection, close the TD RF module, protocol stack; In the above steps, you can also disconnect the TD network connection and then disconnect the PHS network connection, there is no order. Step 370, determining whether to connect to the TD network, if yes, performing the next step, otherwise performing step 400; Step 380, opening the TD radio frequency module, the protocol stack; Step 390, looking for registration to the TD network; If you have not timed out, return to this step to continue registration. As long as the search is finished, you can proceed to the next step. Step 400, determine whether to connect to the PHS network, and if so, perform the next step, otherwise perform step A 420;

Step 410: Turn on the PHS radio frequency module and the protocol stack to search for the PHS network. Step 420: Save the new standby state. Step 430: Adjust the function and display information provided by the MMI to the user according to the new standby state. Considering that the TD search network takes a long time, in order to facilitate the determination and switching of the mode, the state of the mode is determined when the network state of the TD network search ends is reported, and the user can also perform other mode switching at this time. By adopting the above process, the network switching can be directly performed after the MMI menu operation, and the user can be brought back to the user without switching back and forth; f is convenient. The invention realizes the network backup mode switching of the dual-mode dual standby mobile phone with similar frequency points by turning off the radio frequency The business provides an ideal solution for the realization of dual-mode dual-standby mobile phone calls. It overcomes the inability of dual-mode phones to implement calls in dual standby or double-standby to avoid 4 † interference. Or the quality of the service is degraded, resulting in a low degree of user acceptance. At the same time, the mode switching control module introduced effectively controls the mode switching in various situations, simplifies the work of MMI, improves the platform level of dual-mode mobile phones, improves the efficiency of dual-mode mobile phone development, and shortens the dual mode. The cycle of mobile phone research and development reduces the cost of research and development. The above is only the preferred embodiment of the present invention, and is not intended to limit the specific embodiments of the present invention. All modifications and variations made in accordance with the main inventive concept of the present invention are claimed in the claims of the present invention. protected range.
