Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the system for performing call handover according to the embodiment of the present invention includes: a service platform 10 and a second terminal 20.
The service platform 10 is configured to initiate paging to at least one other terminal bound to a second terminal after receiving a handover request of the second terminal that performs a call with a first terminal; and after other terminals are communicated with the first terminal, releasing the session connection between the first terminal and the second terminal.
The second terminal 20 is configured to send a handover request to the service platform after a second terminal in a call with the first terminal needs to perform call handover, so that the service platform initiates paging to at least one other terminal bound to the second terminal; and after receiving a release message of the service platform, releasing the session connection with the first terminal, wherein the release message is sent by the service platform after other terminals are communicated with the first terminal.
The service platform of the embodiment of the invention initiates paging to at least one other terminal bound with a second terminal when receiving a switching request sent by the second terminal which communicates with the first terminal, and releases the session connection between the first terminal and the second terminal after the other terminals are communicated with the first terminal. When the cross-terminal call switching is carried out, the terminal in the call can initiate the switching, and the call is not initiated by the third terminal, so that a new call mode is added, and the method can adapt to more application scenes.
The embodiment of the present invention provides two schemes for performing call handover, which are separately described below.
In the first method, when switching, the service platform initiates paging to all bound terminals.
Specifically, when the second terminal in communication with the first terminal needs to perform call handover, the user may trigger in some manner, so that the second terminal sends a handover request to the service platform.
For example, an APP (computer application), a specific gesture, a button, and the like may be set in the second terminal, and after the user starts the APP, executes the specific gesture, or presses the button, the second terminal sends a switching request to the service platform.
It should be noted that the above manner is only an example, and any triggering manner that enables the second terminal to send the handover request to the service platform is applicable to the embodiment of the present invention.
Correspondingly, after receiving a switching request of a second terminal which communicates with the first terminal, the service platform initiates paging to other terminals bound with the second terminal according to the terminal information which is stored by the service platform and bound with the second terminal.
After the service platform initiates paging to other terminals bound to the second terminal, the other terminals bound to the second terminal receive the call request to ring, and notify the service platform that the terminal has performed ringing (for example, 180ring message is sent to the service platform);
after the other terminals are connected with the first terminal, the other terminals inform the service platform that the other terminals are connected with the first terminal (for example, a 200OK message is sent to the service platform).
Here, the other terminal is connected with the first terminal after receiving the connection command of the user. The on command may be a user click on key trigger, a user voice trigger, a user action trigger, etc. And the other terminals are connected with the first terminal at the signaling level.
After receiving a message that other terminals have communicated with a first terminal (i.e. receiving a first 200OK message), a service platform updates media to the first terminal, and simultaneously sends a message for releasing a call with the first terminal to the second terminal and a terminal which does not establish a session with the first terminal among the plurality of other terminals.
Correspondingly, the second terminal and a terminal which does not establish session connection with the first terminal in the plurality of other terminals release a path with the first terminal after receiving the release message of the service platform.
At this time, the first terminal completes the connection of the media layer with other terminals, establishes a normal call, and completes the call switching from the second terminal to other terminals.
And in the second method, the service platform initiates paging to the appointed terminal when switching.
If a user wants to obtain URI (Uniform Resource Identifier) information of all bound terminals, the user may obtain the URI information by using some manner, for example, when the user opens an APP, the terminal obtains URI information of other terminals bound to a service platform from a core network; the core network sends the URI information of other terminals to the terminal and displays the URI information of other terminals through a UI (User Interface) Interface.
The URI information of the terminal is a call address of the terminal, and includes but is not limited to part or all of the following information: such as code number, domain name information.
It should be noted that the above manners are only examples, and any manner that enables a user to obtain URI information of all bound terminals is applicable to the embodiment of the present invention.
If the user wants to designate a certain bound terminal to perform call switching when the second terminal performing call with the first terminal performs call, the URI information of all the bound terminals can be acquired by the above mode, and the user selects the terminal which wants to perform call switching according to the URI information of the terminal displayed on the UI interface.
After the user selects the terminal, the second terminal sends the switching request containing the appointed terminal to the service platform by adopting some triggering modes.
For example, an APP, a specific gesture, a button, and the like may be set in the second terminal, and when the user starts the APP, executes the specific gesture, or presses the button, the second terminal sends a switching request to the service platform.
Correspondingly, after the service platform receives a switching request of a second terminal which is communicated with the first terminal, the service platform initiates paging to a specified terminal selected by a user according to the terminal information which is stored by the service platform and is bound with the second terminal.
After the service platform initiates paging to the specified terminal bound with the second terminal, the specified terminal bound with the second terminal receives the call request to ring, and notifies the service platform that the terminal has performed ringing (for example, 180ring message is sent to the service platform);
after the designated terminal is connected with the first terminal, the designated terminal informs the service platform that the terminal is connected with the first terminal (for example, sends a 200OK message to the service platform).
The designated terminal is connected to the first terminal after receiving a user's connect command. The on command may be a user click on key trigger, a user voice trigger, a user action trigger, etc. And the connection between the designated terminal and the first terminal is connected in a signaling layer, and the call between the two terminals cannot be realized.
After receiving a message that a designated terminal is connected with a first terminal, a service platform updates media to the first terminal and sends a message for releasing the call established with the first terminal to a second terminal.
Correspondingly, the second terminal releases the session connection with the first terminal after receiving the release message of the service platform.
At this time, the first terminal and the designated terminal complete the connection of the media layer, establish a normal call, and complete the call switching from the second terminal to the designated terminal.
As shown in fig. 2, a first service platform structure for performing call handover according to an embodiment of the present invention includes: at least one processing unit 200 and at least one memory unit 201, wherein the memory unit stores program code which, when executed by the processing unit, causes the processing unit to perform the following:
