The technical problems, the technical solutions, and the advantages of the embodiments of the present invention will be more clearly described in the following description.

The embodiment of the present invention provides a call mode switching control method, which is used in a terminal. The method is as shown in FIG. 1 and includes:

Step 11: When the terminal is in the first call process corresponding to the first call mode, receiving a handover request of the second call corresponding to the second call mode;

Step 12: Cut the first call corresponding to the first call mode according to the handover request After switching to the second call corresponding to the second call mode, the first call is ended.

The call mode switching control method provided by the embodiment of the present invention ends the first call after switching the first call corresponding to the first call mode to the second call corresponding to the second call mode. In the process of the request being responded and completed, the current first call is not interrupted, which improves the user experience.

The call mode switching control method provided by the embodiment of the present invention preferably switches between a voice call and a video television call, and can also switch between a voice call and a SIP call, that is, the first call mode is a voice call mode, where the second call mode is a videophone call mode or a SIP call mode; or

In the current 3G communication and future 4G communication, the videophone may be based on the PS domain, and the switching will be more stable. At the same time, based on the current SIP phones supported by most terminals in Europe and the United States, the call mode switching control method provided by the embodiment of the present invention is also applicable. The difference is that the SIP phone is a simple voice communication based on the SIP protocol stack of the PS domain. When the user has insufficient self-funded and sufficient traffic, or the network traffic communication cost is lower, the voice can be made during the call. Free switching with SIP. Of course, this is based on the assumption that the two call charges are different and the occupied resources are different. The process of switching is controlled by the operator's real-time query fee balance or the user, and the reminder and option for switching the user are also required. And implementation. During the handover process, the first call corresponding to the first call mode is not interrupted, and the first call ends only after the second call corresponding to the second call mode is successfully established.

In the call mode switching control method provided by the embodiment of the present invention, the handover request is initiated by the terminal; or

The handover request is initiated by the network side. When the terminal is in the first call process corresponding to the first call mode, the terminal may initiate a handover request to switch to the second call corresponding to the second call mode, or may initiate the handover request by the network side. The situation in which the handover request is initiated by the terminal is as follows:

A handover request is initiated by a user of the terminal. An example is as follows.

The terminal A is in the first call corresponding to the voice call mode, and the user of the terminal A wants to make a videophone call. At this time, the user can initiate a handover request through the control panel on the terminal interface, requesting to establish a corresponding call mode of the videophone. Second call.

When the network side detects that the network condition is deteriorated or the network handover causes the current call mode to be continuously maintained, the network side device sends a message that the network cannot be maintained to the terminal, and the user of the terminal initiates a handover request according to the message. An example is as follows.

The terminal A is in the first call corresponding to the videophone call mode, and the network side device detects that the current network cannot maintain the videophone call. At this time, the network side device sends a message that the network cannot be maintained to the terminal A, and the user of the terminal A according to the The message initiates a handover request requesting a switch to a voice call mode that requires a relatively low network environment.

Of course, the user of the terminal A can also directly end the current first call according to the message that the network cannot maintain.

In the case that the two types of handover requests are initiated by the terminal, before the second call corresponding to the second call mode is successfully established, the first call corresponding to the first call mode is not interrupted, and the call is guaranteed to be performed in real time, ensuring that the information is not Loss, enhance the user experience, and achieve the object of the present invention. In addition, the handover request can also be initiated by the network side, as follows:

When the terminal is in the first call process corresponding to the first call mode, the handover request is initiated by the communication peer of the first call.

At this time, corresponding to the terminal, it is an action initiated by the network side. An example is as follows. <Example 3>

The terminal A is in the first call corresponding to the voice call mode, and the communication peer that performs the first call with the terminal A is the terminal B, and the terminal B initiates a handover request to switch to the second call corresponding to the videophone mode, with respect to the terminal A. The handover request initiated by the terminal B is an action initiated by the network side.

When the terminal is in the first call process corresponding to the first call mode, the network side initiates the handover request according to the current network environment.

In some call situations, if the network side detects that the network condition is deteriorated or the network switchover causes the current call mode to be unable to continue, the network side device may initiate a handover request to switch the call mode, which is highly demanded by the network environment. The call mode is switched to another call mode that requires relatively low network environment, which further enhances the user experience.

An example of initiating a handover request by the network side is as follows.

The terminal A is in the first call corresponding to the videophone call mode that is required by the network environment. The network side device detects that the current network cannot maintain the videophone call. At this time, the network side device can initiate a handover request to the terminal. .

In the case that the above two types of handover requests are initiated by the network side, before the second call corresponding to the second call mode is successfully established, the first call corresponding to the first call mode is also not interrupted, and the call is guaranteed to be performed in real time, ensuring that no The information is lost, the user experience is improved, and the object of the present invention is achieved. In the call mode switching control method of the embodiment of the present invention, when the handover request is initiated by the terminal, the method further includes:

Sending the handover request to the network side, and confirming, by the network side, whether the handover request is allowed, and returning an indication message to the terminal;

Receiving, by the terminal, the indication message;

When the handover request is initiated by the terminal, it is further confirmed by the network side whether the handover request is allowed, which can further enhance the user experience.

Here, the network side confirms whether the handover request is allowed to be:

When the terminal wants to switch from a call mode with a lower network environment requirement to a call mode that requires a higher network environment, the network side needs to detect whether the current network environment allows the handover request, and returns an indication message of the network environment. The terminal is given to perform a smooth switching of the call mode. An example is as follows.

When the terminal A is in the first call corresponding to the voice call mode with lower network environment requirements, the terminal A initiates a handover request, and requests to switch to a videophone call mode that requires a higher network environment, and the network side device detects the current call. Whether the network can maintain the videophone call, return an indication message of the network environment to the terminal, so as to perform a smooth switching of the call mode.

In order to improve the user experience, when the terminal initiates a handover request, the first call should be confirmed. Whether the communication peer agrees with the handover request. Sending the handover request to the communication peer end, according to whether the information of the handover request is allowed to be returned to the terminal returned by the communication peer end, so as to perform smooth handover of the call mode. An example is as follows.

The terminal A is in the first call corresponding to the voice call mode, and the communication peer that performs the first call with the terminal A is the terminal B, and the terminal A initiates a handover request to switch to the second call corresponding to the videophone mode, and the terminal B receives the handover request. After the handover request, it returns whether the information of the handover request is allowed to the terminal A, so as to perform a smooth handover of the call mode.

The call mode switching control method provided by the embodiment of the present invention can smoothly switch to another session mode without interrupting the current call mode when the network can be carried. Of course, the request can also be initiated by the opposite end of the call. For the other end of the call, it is the action initiated by the network side. In the process of the request being responded and completed, the current call will not be interrupted, and such a request will be responded to by the network, and finally the call mode desired by the user can be normally established, thereby improving the user experience.

The embodiment of the invention further provides a call mode switching control device, which is used for a terminal, and the device is as shown in FIG. 2, and includes:

The call mode switching control apparatus, where the handover request is initiated by the terminal; or

The handover request is initiated by the network side.

Initiating the handover request by a user of the terminal; or

a second receiving module, configured to receive, by the terminal, the indication message;

When the indication message indicates that the handover request is permitted, the switching module switches the first call corresponding to the first call mode to the second call corresponding to the second call mode according to the handover request. End the first call.

The embodiment of the present invention further provides a terminal, comprising the call mode switching control apparatus according to any one of the above items.

In the following, the voice call mode is switched to the video call mode as an example, and the overall process of the call mode switching control in the embodiment of the present invention is specifically described.

Branch 4, the modem will return the query result to the network status query part; branch 5, the network status query part will judge according to the result returned by the modem, if the current network status allows to initiate a video call, enter branch 6, otherwise, enter the branch 7; Branch 6, the network status allows to initiate the videophone to inform the modem, enter branch 8; Branch 7, report the result of this request to the control layer, the upper layer will prompt the user to prompt the user according to the received result Reason value,

Branch 8, confirm to the communication peer of the first call whether to allow the call to be initiated, at this time, the upper layer code will judge whether the other party allows the result, if the other party does not allow, then enter the branch 9, otherwise enter the branch 10;

Branch 9, returns the result of the communication peer rejection to the upper application, and the upper interface also gives the corresponding error prompt;

Branch 10, the communication peer allows, at this point, the protocol stack of the videophone is started, and the protocol stack also informs the modem of the local startup action, since the current switching action is in the first call. Therefore, there is no need to restart a call-up action as if the call was made normally; branch 11, the modem opens the multimedia channel for the request of the protocol stack, and after the multimedia channel is successfully opened, the modem notifies the protocol stack of the message;
