Description

Method for realizing double-mode mobile terminal double-machine call

Technical field

The present invention relates to a dual mode mobile terminal, and more particularly to a method for a dual mode mobile terminal to implement a call during a standby operation. Background technique

As a 3G network independently researched and developed by China, TD-SCDMA (Time Division Synchronous Code Division Multiple Access, hereinafter referred to as TD) network will start trial operation in 2006, but in the initial stage of construction, it has to face the problem of insufficient network coverage. If you can't solve this real problem, it will greatly affect the development of TD network users, and thus affect the development of TD network in China and the world. To solve this problem, the best solution at present is nothing more than supplementing the network with TD network by means of other networks. In the environment where TD network exists, users can use the superior performance of 3G network. When there is no TD network, Ability to use other network services to ensure normal communication for users. The already mature GSM network just meets the above conditions. If TD/GSM dual-mode dual standby mobile terminal equipment is adopted, it can meet the needs of TD+GSM network.

At present, the existing TD mobile terminal equipment runs at 2010 ~ 2025MHz, while the GSM dual-band mobile terminal operates at 900MHz and 1800MHz, so the TD/GSM dual-mode mobile phone can operate in its own frequency band. Since even if GSM is running at 1800MHz, the working frequencies of the two networks are 200MHz, which will not affect the call.

After the TD/GSM dual-mode mobile terminal is powered on normally, it can have the following three standby states: TD network machine). When the TD or GSM network is single standby, the TD/GSM dual-mode mobile terminal is equivalent to a TD mobile phone or a GSM mobile phone in the usual sense. Although dual mode terminals are well known in the art, no processing has been proposed for implementing a dual standby call when the mobile terminal simultaneously receives terminal calls from both TD and GSM mobile communication systems. At present, other dual-mode terminals also have the same problem, and can only directly display new incoming calls. If a new incoming call is connected, the current call will be hung up. Summary of the invention

The problem to be solved by the present invention is to provide a method for implementing a dual standby mobile terminal by using a dual mode mobile terminal, which can simultaneously receive a call from a terminal of a current standard or another standard when the dual mode mobile terminal is silent standby, without hang up the current call.

In order to solve the above technical problem, the present invention provides a method for implementing a dual standby mobile terminal dual standby call, the dual mode mobile terminal A having a first control module for the first network standard and a second network standard for The second control module, the terminal A is in the dual standby mode, and is in a call state with the second mobile terminal B by using a network standard. When the terminal A receives the call of the third mobile terminal C, the terminal performs the following steps:

(a) Terminal A receives the call request initiated by the terminal C. If it is determined that the network standard of the current call supports the call hold service, when the terminal A selects the call to pick up the terminal C, the terminal A suspends the call of the terminal B, and the terminal B Enter the call hold state;

(b) Terminal A determines whether the network standard of the call of the terminal C is consistent with the current network standard. If yes, the call hold service is started, and the call with the terminal C is turned on. If not, the voice input/output module of the terminal A is switched. The control is given to the control module of the corresponding network standard, and the call with the terminal C is connected.

Further, the foregoing method may further have the following features: In the step (a), if it is determined that the network standard of the current call does not support the call hold service, the call of the terminal C is directly hanged by "the user is busy"; The network standard of the call supports the call waiting service. When the terminal A chooses to hang up or hang up the call of the terminal C with "the user is busy", the terminal A continues to maintain the call state with the terminal B.

Further, the foregoing method may further have the following features: after the step (b), in the process of performing call hold, the terminal A determines the network standard of the current call after receiving the command of switching the call sent by the user. Support call hold, suspend the current call, switch the control of the voice input and output module in terminal A to the control module of the corresponding network standard, activate the previously suspended call, and if it is determined that the current call network system does not support call hold, then Prompt the user to switch.

Further, the above method may further have the following features: after the step (b), when the terminal When the user of A presses the on-hook key, the current call is ended. If there are other calls in the call hold state at this time, it is activated to the call state.

Further, the foregoing method may further have the following features: the dual mode mobile terminal A is a TD/GSM dual mode mobile terminal, the first network standard is TD-SCDMA, and the first control module is a TD control module, where the The second network standard is GSM, and the second control module is a GSM control module.

In order to solve the above technical problem, the present invention further provides a method for implementing a dual standby mobile terminal dual standby call, the silent mode mobile terminal A having a first control module for the first network standard and for the second network standard The second control module, the terminal A is in the dual standby mode, and is in a call state with the second mobile terminal B by using a network system. When the terminal A dials the call of the third mobile terminal C, the following steps are performed:

(A) The user of terminal A initiates a call with terminal C, and if terminal A determines that the network standard of the current call supports call hold service, the current call is suspended;

(B) Terminal A determines whether the initiated call is consistent with the network mode of the current call. If they are consistent, the call hold service is started, and the call with terminal C is turned on. If not, the control of the voice input/output module in terminal A is switched. Start a new call to the control module of the corresponding network standard.

Further, the foregoing method may further have the following features: In the step (A), if it is determined that the network standard of the current call does not support the call hold service, an error is indicated.

Further, the foregoing method may further have the following features: after the step (B), in the process of performing call hold, the terminal A receives the command of switching the call sent by the user, and determines the network standard of the current call. Support call hold, suspend the current call, switch the control of the voice input and output module in terminal A to the control module of the corresponding network standard, activate the previously suspended call, and if it is determined that the current call network system does not support call waiting, Prompt the user to switch.

Further, the above method may further have the following features: When the user of the terminal A presses the on-hook button, the current call is ended, and if other calls are in the call hold state at this time, the call is activated to Call status.

The dual-mode mobile terminal adopting the method can implement the normal interference-free call by using the device switching and the additional service provided by the network without changing the current network parameters, and can implement the call waiting and call holding functions of the dual-mode terminal. There is no need to hang up the current call when making a new call. In addition, for TD/GSM dual-mode mobile terminals, since the two modes of standby are used in TD and GSM, when the call is sent, the working frequency of the GSM operation is only 200MHz when the GSM operation is at 1800MHz, so no signal interference occurs. To ensure the quality of the call. The implementation of the invention not only meets the requirement of the user to use a dual mode terminal to make a call, but also satisfies the requirement that the user normally uses another system to make a call, and realizes two modes of the silent mode mobile phone at the same time.

Preferred embodiment of the invention

The above and other objects, features and advantages of the present invention will become more apparent from the detailed description of the embodiments of the invention.

FIG. 1 is a mobile communication system environment in which a TD/GSM dual-mode mobile terminal can work normally in the embodiment. The area 1 is a service area covered only by the GSM network, and the area 2 is a service area covered only by the TD network. This embodiment mainly relates to the case of the area 3, that is, the mobile terminal is operated at The case where the T network and the GSM network are simultaneously covered.

Using the protocols operated by existing TD and GSM networks, the TD and GSM networks each provide call waiting and call hold functions for additional services. When the mobile terminal is in the call flow on the system supporting call waiting and call hold services, if a third party call request is received, the current call may be suspended, and the mobile terminal maintains the current radio frequency status, and the user can receive new calls. Call business. The user can also initiate another call service in another mode in the call. Assuming that the two types of networks support the above-mentioned additional services, it is possible to freely switch between the two types of calls.

Call waiting means that when a user calls during a call, when the third party calls in, the system will receive a prompt for the new incoming call. The user is free to decide to answer, reject, or ignore the call without hanging up the ongoing call. The other party will also hear the voice prompt later. If the call waiting feature is not activated, it is the same as the normal call.

Call hold means that when the user is on a call, the current call can be suspended, a third party can be called or another call can be answered, and the user can switch between the two calls.

FIG. 2 is a schematic diagram of the hardware system of the TD/GSM dual-mode mobile terminal in the embodiment. The dual-mode mobile terminal is composed of two control modules, GSM and TD, and the GSM module is used as a system main controller, and is responsible for general equipment such as a GUI (Graphic User Interface), an audio device, a FLASH (flash memory), a motor, and the like. Management, and management of SIM card and GSM RF module; TD module is system auxiliary controller, responsible for management of USIM card and TD radio. The voice input/output module (MIC and handset) is controlled by a switch that can be handed over to the GSM module or TD module upon request.

For TD/GSM dual-mode mobile terminals with TD modules as the system's main controller, the following procedure is also applicable.

When the above TD/GSM mode mobile terminal is in the area covered by both the TD network and the GSM network, and the GSM and TD networks can provide call waiting and call hold functions for additional services, this document only describes the TD/GSM dual mode terminal dual. The operation flow of the TD call during the GSM call in the standby state, and the operation procedure of the GSM call during the TD call is the same.

In this embodiment, the TD/GSM dual-mode mobile terminal A, the second mobile terminal B, and the third shift are involved. The mobile terminal C, wherein the TD/GSM dual-mode mobile terminal A is in a dual standby state, and the terminal B and the terminal C may be dual-mode mobile terminals or ordinary single-standard mobile terminals, and the terminal A in this embodiment , B, and C support call waiting and call hold functions.

In the embodiment, when the TD/GSM dual-mode mobile terminal is dual standby, the method for receiving a call, as shown in FIG. 3, includes the following steps:

Step 301: The TD/GSM dual-mode mobile terminal A is in a dual standby mode, and a system (for example, GSM) and the mobile terminal B are in a call state;

The mobile terminal A can be a calling party or a called party. When the mobile terminal A and the mobile terminal B start the call flow, the mobile terminal A hands over the control of the MIC and the handset to the GSM control module according to the current system state (if the control rights of the MIC and the handset are already on the GSM module side, No need to), after starting the call, the interface displays the network mark of the current call and the call information (such call duration, etc.).

Step 302: At this time, the mobile terminal A receives the call request initiated by the third party mobile terminal C. Step 303: The terminal A determines whether the current call system (for example, GSM) supports the call hold service. If not, the terminal A directly uses the The user is busy "hang up the call from terminal C. If supported, perform the next step;

When the called phone is on a call, the caller will hear a busy tone. In the past, the voice was rushing to "beep," and now it is generally "the phone you are calling is in a call, please wait Re-dial" prompt, the local abbreviation "user busy,, or "user is busy, (subscriber busy).

Step 304: The terminal A determines whether the user chooses to answer the call. If yes, the next step is performed. If the user chooses to hang up or hang up the call of the terminal C in the "user busy" manner, the terminal A continues to maintain the call state with the terminal B. ;

If the current call system supports call hold, the mobile terminal A displays a prompt, and can also ring the prompt or prompt.

Hanging up and hanging up directly in the "user busy" mode is no different for terminal A. However, for caller C, the system prompt tone is different. When the user is busy, the system will hang up. When you hear the prompt, you can know that the current status of A is in the middle of a call, and the direct hang up is a normal "beep~beep" sound. Step 305, the user presses the answer button, the mobile terminal A suspends the call of the terminal B, and the terminal B enters the call hold state;

Step 306, the mobile terminal A determines whether the network standard of the call of the terminal C is consistent with the current system. If the call is consistent, that is, it is also GSM, the service of the GSM call hold is started, and the call is started with the terminal C. If the call is inconsistent, for example, TD, Switch the control of the MIC and the handset to the controller of the TD module, and then start a new call to the TD.

When the mobile terminal A suspends the call of the terminal B, the terminal B hears the voice prompt being held. When the user of the terminal A presses the on-hook key, the current call with the terminal C is ended. If the terminal B is still in the call hold state, the state is activated to the call state.

During the call between terminal A and terminal B, terminal A can receive a new incoming call or make a new call. The above is the process of receiving new calls. The following is the process of making a new call (as shown in Figure 4), including the following steps:

Step 401: The TD/GSM dual-mode mobile terminal A is in a dual standby mode, and a system (for example, GSM) and the mobile terminal B are in a call state;

Step 402: The user of the terminal A initiates a call with the third-party terminal C.

Step 403: Terminal A determines whether the network standard of the current call supports call hold. If not, the terminal prompts an error and returns to the call state of the terminal B. If supported, the call with the terminal B is suspended, and the next step is performed;

Step 404: The terminal A determines whether the initiated call is consistent with the current call system. If the call is consistent, the service of the call hold is started, and the call with the terminal C is started. Otherwise, the control of the MIC and the handset is switched, and a new call is started.

In the process of performing call hold, the terminal A can switch between the terminal B and the terminal C through an MMI (Man Machine Interface). When the user switches from the call with the terminal B to the terminal C (the user issues a handover command to the terminal A by pressing a predetermined switch key), the terminal A first determines whether the network standard of the current call supports call hold, and if not, prompts The user cannot switch; if supported, suspends the call with terminal B, switches the MIC and the handset Control, re-activate the terminal C call that was suspended before;

If terminal B or C hangs up when it is suspended, terminal A is in a one-way conversation.

When the user of terminal A presses the on-hook key, the current call is ended. If there are other calls in the call hold state at this time, the state is activated to the call state.

After making all the calls, the mobile terminal returns control of the MIC and the handset to the current master controller.

In the above method, all the judgments are automatically made in the call, and the operation of the other is the same as that of the single-mode mobile phone except for the different icons on the interface.

In the dual standby mode of GSM and TD, since the radio frequency of the two does not cause signal interference or has little influence, this method can realize the mobile terminal that performs the silent mode call while in standby.

It should be understood that those skilled in the art to which the present invention pertains may make corresponding equivalent changes or substitutions according to the technical solutions of the present invention and the concept thereof, for example, the present dual-mode mobile terminal is applicable to the present method. For example, a GSM/CDMA dual mode mobile terminal, a PHS/CDMA dual mode mobile terminal, a PHS/GSM silent mode mobile terminal, etc., all of which are subject to the scope of protection of the appended claims.

Industrial applicability

The dual-mode mobile terminal adopting the method can implement the normal interference-free call by using the device switching and the additional service provided by the network without changing the current network parameters, and can implement the call waiting and call holding functions of the dual-mode terminal. There is no need to hang up the current call when making a new call. In addition, for the TD/GSM dual-mode mobile terminal, since the standby mode is adopted in the two modes of TD and GSM, when the call is sent, the working frequency of the GSM operation is only 200 MHz when the GSM operation is at 1800 MHz, so no signal interference occurs. Guarantee the quality of the call. The implementation of the invention not only meets the requirement of a user to use a dual mode terminal to make a call, but also satisfies the requirement that the user normally uses another system to make a call, and realizes two modes of the dual mode mobile phone simultaneously standby.
