Fig. 1 is a flowchart illustrating a group call method according to an embodiment of the present invention, where an execution subject of the method according to the embodiment may be a user equipment, and the user equipment may specifically be a device supporting a trunking communication technology, such as a private network mobile phone. As shown in fig. 1, the method of this embodiment may include:
In this step, the group call type of the target group is a group call with different video sources, and the services supported by the target group may include a voice group call service and a video push to group service. Optionally, the first user instruction may instruct the target group to switch from the group call with the different video sources to the voice group call, and after the target group is switched from the group call with the different video sources to the voice group call, the target group supports the service of the voice group call and does not support the service of the video group to the group; or, the first user instruction may instruct that the group call is switched from the different video source group call to the video push to group, and after the group call is switched from the different video source group call to the video push to group, the service of the video push to group is supported in the target group, and the service of the voice group call is no longer supported.
It should be noted that, the present invention is not limited to a specific manner of acquiring the first user instruction input by the user. Optionally, the first user instruction input by the user may be acquired through a physical key or a virtual key. For example, the first user instruction may be an instruction to stop pushing a video button clicked by a user, and is specifically used to instruct switching from a different source video group call to a voice group call.
It should be noted that the user in the embodiment of the present invention may be different from the scheduler having the service scheduling authority in the target group, and the user equipment in the embodiment of the present invention specifically refers to the user equipment used by the user in the target group, and is not the equipment used by the scheduler in the target group.
In this step, the user equipment and the core network device may communicate with each other in a wireless communication manner, and optionally, the first message may be Non-access stratum (NAS) layer signaling. It should be noted that, the present invention may not be limited to the specific manner in which the first message indicates the request for switching the target group from the different source video group call to the first group call type. Optionally, the first message may include indication information, and the indication information may be used to indicate the first group call type.
The core network device may specifically be any entity device that implements a core network function.
It should be noted that the first message may be an existing message, and the target group is requested to be switched from the different source video group call to the first group call type by adding a field in the existing message; alternatively, the first message may be a new message. Here, the existing message refers to a message that already exists in the prior art, and the new message refers to a message that does not exist in the prior art.
In this step, the second message is determined by the core network device according to the first message and is used to indicate that the target group is switched from the different source video group call to the first group call type.
It should be noted that, the present invention may not be limited to the specific manner in which the second message indicates to switch the target group from the different source video group call to the first group call type. Optionally, the indication message may include indication information, and the indication information may be used to indicate the first group call type.
And 104, switching the group call type of the target group into the first group call type according to the second message.
In this step, after receiving the second message, the ue may switch the group call type of the target group, and specifically, may switch the group call type of the target group from a different source video group call to the first group call type.
Optionally, the switching the group call type of the target group to the first group call type may specifically include: prompting the user that the current group call type of the target group is a first group call type so that the user can know the current group call type of the target group; and/or canceling the display of content associated with the second group call type. For example, when the first group call type is a voice group call, the second group call type is a video push to group, a video window for displaying a video can be cancelled, and when no video content exists in the video window, the video window without the video content can be prevented from being displayed to a user, so that the user experience is improved. For another example, when the first group call type is a video Push to group, and the second group call type is a voice group call, it may indicate that no person is currently speaking in the target group, the voice resource is released, and a Push To Talk (PTT) button may be pressed to reestablish the voice group call.
In this embodiment, a first message for requesting that a target group is switched from a different-source video group call to a first group call type is sent to a core network device according to user input, a second message sent by the core network device according to the first message and used for indicating that the target group is switched from the different-source video group call to the first group call type is received, and the group call type of the target group is switched to a second group call type according to the second message, so that the user device interacts with the core network device according to user instruction triggering to switch the target group from a different video source to a voice group call or video push to the group, thereby switching the different video source group call to the voice group call or video push to the group is realized, and flexibility of switching the group call type is improved.
Fig. 2 is a schematic flow diagram of a group call method according to another embodiment of the present invention, where an execution main body of the method according to this embodiment may be Core Network equipment, and the Core Network equipment may specifically be any entity equipment that implements a function of a Core Network, where the Core Network may be an evolved Core Network (eCN), for example. As shown in fig. 2, the method of this embodiment may include:
In this step, for the description about the first message, reference may be made to the embodiment shown in fig. 1, which is not described herein again.
In this step, optionally, step 202 may specifically include: after receiving the first message, a second message may be sent to all user equipments within the target group.
Or after receiving the first message, one or more judgments may be performed, and when the judgment result is the first judgment result, the second message is sent to all the user equipments in the target group. Further, when the determination result is the second determination result, the second message may not be sent to all the user equipments in the target group.
Optionally, the determining may include whether the group call type of the target group is a group call with a different video source. Correspondingly, when the group calling type of the target group is a group calling of different video sources (namely, a first judgment result), a second message is sent; when the group call type of the target group is not a group call of a different video source (i.e., the second judgment result), the second message is not sent.
Optionally, the determining may include whether the group call type of the target group is a group call with a different video source, and whether a function switch allowing the user to switch the group call type from a group call with a different video source to a group call with a voice or a video is turned on. Correspondingly, when the function switch is turned on and the group call type of the target group is a group call of different video sources (namely, a first judgment result), a second message is sent; and when the function switch is not started or the group calling type of the target group is not the group calling of different video sources (namely, a second judgment result), not sending a second message.
It should be noted that all the ue devices in the target group include: and the user equipment sends the first message to the core network equipment.
In this embodiment, by receiving a first message sent by a user equipment and used to request a target group to be switched from a different-source video group call to a first group call type, and sending a second message to all user equipments in the target group according to the first message, where the second message is used to indicate that the target group is switched from a different-source video group call to the first group call type, the core network equipment switches the target group from a different-source video group call to a voice group call or video push to a group according to the request of the user equipment, thereby switching the different-source video group call to the voice group call or video push to the group is achieved, and the flexibility of switching the group call types is improved.
Optionally, based on a call release flow of a group in the related art, switching of a group call of different video sources to a voice group call or video push to a group may be implemented. Optionally, for a group call of different video sources is switched to a video push group, it may be considered to release a voice group call; for switching different video sources to a voice group call, it can be considered to release video push to the group. In particular, reference may be made to the embodiments shown in fig. 3 and 4 below.
Fig. 3 is a flowchart of a group call method according to another embodiment of the present invention, and this embodiment mainly describes an optional interaction process between a user equipment and a core network device based on the method embodiments shown in fig. 1 and fig. 2. As shown in fig. 3, the method of this embodiment may include:
step 301, a User Equipment (UE) sends a call release Request (call release Request) message to a core network device.
In this step, the call release request message is used to request the target group to be switched from a different source video group call to a video push group. Currently, the paging release request message is used to release the target group, and after the target group is released, the ues in the target group cannot communicate. In the embodiment of the present invention, a field, for example, a Call Type (Call Type) field, may be added in the Call release request message, and a value of the field may be equal to an identifier of the voice group Call, and is used to request to release the voice group Call, that is, to request to switch from a different source video group Call to a video push to group.
It can be seen that, here, the call release request message does not indicate to release the session of the target group, but only releases the voice group call in the group call of different video sources of the target group.
It should be noted that, before step 301, the group call type of the target group is a group call with different video sources, and all the user equipments in the target group may be in group calls with different video sources.
Optionally, the user using the user equipment may be a user initiating a voice call in the target group. That is, a user initiating a voice call may be allowed to release the voice group call. Here, the user who initiates the voice call in the target group may provide a control manner in which the user who initiates the voice call in the target group switches the different source video group calls to video push to the group. That is, the user who initiates the voice group call releases the voice group call, so that the consistency of the authority can be realized. It will be appreciated that the user may be any user in the target group that uses a user device, regardless of the issue of consistency of permissions.
Step 302, after receiving the Call Release request message, the core network device returns a Call Release Response (Call Release Response) message to the user equipment.
In this step, the release response message may be a response message to the release request message, and may indicate that the core network device receives the call release request message sent by the user equipment.
It should be noted that, the specific meaning of the call release response message is consistent with the related description in the existing broadband trunking (B-TrunC) standard, and is not described herein again.
Step 303, the core network device sends a Group Call Setup Indication (Group Call Setup Indication) message to all the user devices in the target Group.
In this step, the group call setup indication message may include an identifier of video push to group, which is used to indicate that the group call type is changed to video push to group. It should be noted that, the specific meaning of the group call setup indication is consistent with the related description in the existing broadband trunking (B-TrunC) standard, and is not described herein again.
Optionally, the core network device may also release the resources allocated to each user equipment for the voice group call.
It should be noted that after step 303, the group call type of the target group is video push to group, and all the user equipments in the target group may be in video push to group.
In this embodiment, the user equipment sends the call release request message for instructing to release the voice group call to the core network equipment, and the core network equipment sends the group call establishment instruction message for instructing to change the group call type from the video push to the group to all the user equipment in the target group, so that based on the interaction between the user equipment and the core network equipment, the target group is switched from the group call with different video sources to the video push to the group, and the flexibility of switching the group call type is improved.
Fig. 4 is a flowchart of a group call method according to another embodiment of the present invention, and this embodiment mainly describes another optional interaction process between the user equipment and the core network device based on the method embodiments shown in fig. 1 and fig. 2. As shown in fig. 4, the method of this embodiment may include:
step 401, a User Equipment (UE) sends a call release Request (CallRelease Request) message to a core network device.
In this step, the call release request message is used to request the target group to be switched from a video group call with different sources to a voice group call. Currently, the paging release request message is used to release the target group, and after the target group is released, the ues in the target group cannot communicate. In the embodiment of the present invention, a field, for example, a Call Type (Call Type) field, may be added in the Call release request message, where a value of the field may be equal to an identifier of video push to a group, and is used to request to release video push to the group, that is, to request to switch from a different source video group Call to a voice group Call.
It can be seen that here, the call release request message does not indicate to release the session of the target group, but only releases the video push to the group in the group call of the different video sources of the target group.
It should be noted that, before step 401, the group call type of the target group is a group call with different video sources, and all the user equipments in the target group may be in group calls with different video sources.
Optionally, the user using the user equipment may be the user who pushed the video in the target group. That is, a user pushing a video may be allowed to release the video push to the group. Here, the user who pushes the video in the target group may provide a control mode in which the user who pushes the video in the target group switches the different source video group call to the voice group call. That is, the user who initiates the voice group call releases the video push to the group, so that the consistency of the authority can be realized. It will be appreciated that the user may be any user in the target group that uses a user device, regardless of the issue of consistency of permissions.
Step 402, after receiving the Call Release request message, the core network device returns a Call Release Response (Call Release Response) message to the user equipment.
In this step, the release response message may be a response message to the release request message, and may indicate that the core network device receives the call release request message sent by the user equipment.
It should be noted that, the specific meaning of the call release response message is consistent with the related description in the existing broadband trunking (B-TrunC) standard, and is not described herein again.
Step 403, the core network device sends a Group Call Setup Indication (Group Call Setup Indication) message to all the user devices in the target Group.
In this step, the group call setup indication message may include an identifier of the voice group call, which is used to indicate that the group call type is changed to the voice group call. It should be noted that, the specific meaning of the group call setup indication is consistent with the related description in the existing broadband trunking (B-TrunC) standard, and is not described herein again.
Optionally, the core network device may further release resources allocated to each user equipment for video push to the group.
It should be noted that, after step 403, the group call type of the target group is a voice group call, and all the ues in the target group may be in the voice group call.
In this embodiment, the user equipment sends a call release request message for instructing release of video push to the group to the core network equipment, and the core network equipment sends a group call establishment instruction message for instructing a group call type to be changed to a voice group call to all the user equipment in the target group, so that based on interaction between the user equipment and the core network equipment, switching of the target group from a group call with a different video source to a voice group call is realized, and flexibility of switching of the group call type is improved.
Fig. 5 is a flowchart illustrating a call release of a group in the related art, and as shown in fig. 5, the method may include:
step 501, a User Equipment (UE) sends a call release Request (call release Request) message to a core network device.
In this step, the call release request is used to request to release the session of the target group. Optionally, in order to ensure consistency with the related art, the Call release request message may not carry the newly added field, for example, a Call Type (Call Type) field.
