Description
Technical Field
The invention relates to a communication technology, in particular to a method and a system for a dispatching desk to join a group call.
Background
The trunking communication system is developed for meeting the demand of industry user command and dispatch, and is a special wireless communication system applied to a specific industry. The cluster communication system has wide application markets in the fields of government departments, public safety, emergency communication, electric power, civil aviation, petroleum, ports and the like.
The broadband trunking communication system based on the TD-LTE technology takes the TD-LTE as a core technology, combines the characteristics of high speed and large bandwidth of the TD-LTE with the characteristics of resource sharing, quick call establishment, command scheduling and the like in the digital trunking technology, and is a communication system capable of providing high-speed data transmission. The visual group call service is the most basic service provided by the broadband trunking communication system, and is divided into a homologous video group call and a non-homologous video group call. The group call of the homologous video refers to a group call service initiated by a terminal or a dispatching desk aiming at one group, wherein the group call service comprises two media streams of voice and video, and the voice and the video are from the same speaking right party.
When a group call is initiated, if a group member includes a Dispatch station (DC), a cluster server of the cluster core network sends a group call setup request message to the Dispatch station, and triggers the Dispatch station to answer the group call as a called party. In the process of maintaining the group call service, the dispatching desk can actively hang up the group call through the interface, after the group call is hung up, the cluster server does not send audio and video data to the dispatching desk any more, and other group members cannot influence the group call answering.
After the dispatching station hangs up a certain group calling service, if the dispatching station subsequently dials the group calling, the B-trunk (broadband trunking core network) standard has no provision for the scene.
The only solution for reference is that a group call is established in the B-TrunC standard end-to-end flow, and the terminal initiates the description of establishing the group call.
Fig. 1 shows a signaling interaction flow diagram of the scenario.
As shown in fig. 1, a group call is established, and a flow of a terminal initiating establishment of the group call is described as follows:
the cluster server of the cluster core network receives a Group Call establishment Request (Call Request) of the terminal UE, and if it is determined that the Group Call requested by the UE is already established, the Group Call requested by the UE is UEs and the Group Call of the cluster base station is already established, the cluster server is in a continuous Group Call (Group Call) state. And meanwhile, discovering that the cell where the UE is located does not establish a group calling related channel with the established cluster base station, triggering the cell where the UE is located to establish a downlink group calling bearing resource with the established cluster base station by the cluster server, configuring the related channel for the cell where the UE is located, and periodically broadcasting cluster paging and group calling configuration messages.
The cluster server compares the user priority of the UE with the priority of the speaking right user in the established group calling, if the user priority of the UE is judged to be lower than the current speaking right user, the cluster server can directly reject the speaking right application of the user, and sends a message to inform the UE that the group calling is established and the speaking right application is rejected; it may also send a message to inform the UE that the group call is established, receive the group call request, and be in the floor queuing queue.
If the user priority of the UE is higher than the speaking right user, directly granting the speaking right of the UE in the established group calling, sending and receiving a group calling request (Call Accept) to inform the UE to Complete the bearer establishment, and replying the message of completing the group calling (Call Complete) by the UE.
And the method is consistent with the normal group call establishment process from the terminal point of view. The terminal can join the cluster group call in a passive delayed access mode and an active delayed access mode.
It should be noted that, when the call type applied by the UE is inconsistent with the already established group call type, for example, the UE applies for establishing the voice group call but the already established active group is a video group call, or the UE applies for the video group call but the already established active group is the voice group call. The cluster server sends a message to reject the call request of the UE, and the message carrying reason is the conflict between the UE and the network side process.
The prior art only discloses the flow that the terminal initiates the request for the group call as described above, but the B-TrunC standard in the prior art is not established for the group call, and the scheduling station lacks a processing description of the scenario for the relevant description of the flow that the scheduling station initiates the request for the group call.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention.
Currently, the B-TrunC standard lacks a description of the processing of the scenario when the dispatching station re-initiates the group call service to the group in the call.
Fig. 2 is a flowchart illustrating a method for a dispatching desk to join a group call according to an embodiment of the present invention; fig. 3 is a signaling interaction diagram illustrating a method for a dispatching desk to join a group call according to an embodiment of the present invention; referring to fig. 2 and fig. 3, a method for a scheduling station to join a group call provided by an embodiment of the present invention specifically includes the following steps:
101. the method comprises the steps that a cluster core network element receives an establishment request which is sent by a dispatching desk and used for requesting to establish a group call service, wherein the establishment request carries a group call group identification and a group call type identification (call type).
In practical applications, the group call group id may be a group number, a group call join code, a group call verification code, or other information. The group call type identifier may be a call type identifier, for example, the call type may be a voice group call or a visual group call.
For example, the above establishment request may further include: media parameters corresponding to the call type.
For example, when the call type is voice group call, the media parameters may be basic parameters such as voice format and voice bearer. When the call type is visual group call, the media parameters may be video format, resolution, color digit, default scaling, voice parameters, compatibility standard, interface standard, etc.
It is understood that, in a specific sending process, the above-mentioned establishment request may be a SIP message, and the actually sent SIP message may further include one or more of the following: call Priority attribute identification (Priority attribute, PrioAttribute), End-To-End encryption indication information (E2 EE), simplex and duplex indication information (duplex), service identification (Push To Talk Call, pttcall), and the like.
102. And the cluster core network element checks whether the group calling group corresponding to the current group calling type is carrying out the group calling service according to the group calling group identification and the group calling type identification.
That is, the trunking core network element checks whether a group call is established, checks whether the type of the group call group is the group call type sent by the dispatching desk after the group call is established, and executes the following step 103 if all the types are consistent. 103. And sending a response allowing to join the group call group to the dispatching desk, wherein the response carries the speaking right authorization information.
That is to say, after the dispatching station joins the current group call group, the cluster core network may transfer the speaking right to the dispatching station, and at this time, the cluster core network may also send an NAS message to all terminals in the group call, where the message carries indication information for explaining the speaking right state.
In this embodiment, the trunking core network element may authorize the right to speak to the dispatching station by default without considering the relationship between the priority of the dispatching station and the user priority of the currently ongoing group calling party and the current right to speak terminal.
If the group call in step 102 is not established, the trunking core network performs a group call establishment process according to an establishment request sent by the scheduling station for requesting establishment of a group call service, and if the group call is already established, but the group call types are inconsistent, the following description may be referred to at this time.
It can be understood that, in practical applications, after receiving the establishment request for requesting to establish the group call service sent by the scheduling station, the trunking core network may send a response to the scheduling station, where the response is used to indicate that the current core network is processing the request.
For example, the trunking core network element sends a response, such as a SIP (100Trying) message, to the dispatching desk to indicate that processing is in progress.
In the method for adding a group call to a dispatching station provided by this embodiment, when the dispatching station requests to establish a group call service, after determining that a group call group corresponding to a current group call type is performing the group call service, a cluster core network element sends a response to the dispatching station, the response carrying speaking right authorization information, as a standard supplement, to allow the dispatching station to add the group call group, and provides a solution when the dispatching station requests to establish a group call and the group call group is performing the group call service.
In an alternative embodiment of the present invention, after step 102 of the above method, the method further includes step 104, not shown:
104. and the cluster core network element checks that the group calling group corresponding to the current group calling type does not carry out the group calling service, establishes the group calling according to the establishment request and sends a group calling establishment response to the dispatching desk.
In another alternative embodiment of the present invention, after step 102 of the above method, the method further comprises step 105, not shown in the figure:
105. if the cluster core network element determines that the group calling group is carrying out the group calling service, but the group calling type of the group calling service is inconsistent with the group calling type corresponding to the group calling type identification in the establishment request; then when the group call type of the currently ongoing group call service is a voice group call, and the group call type identifier is a visual group call identifier,
the cluster core network element adjusts the group calling type of the ongoing group calling service to the group calling type corresponding to the group calling type identification in the establishment request, and simultaneously sends an adjustment request for adjusting the group calling type to the base station to which each terminal in the group calling group belongs; and the base station to which each terminal in the group call group belongs interacts with each terminal according to the adjustment request so as to adjust the group call type of the currently established and ongoing group call group.
Specifically, the trunking core network element checks the group call type of the group call service and the group call type corresponding to the group call type identifier in the establishment request. And if the group call type of the current ongoing group call service is a voice group call and the group call type identifier is a visual group call identifier, the cluster core network element adjusts the ongoing voice group call to a visual group call.
Of course, after the group call type is adjusted, an adjustment request for adjusting the group call type needs to be sent to the base station to which each terminal in the group call group belongs, where the adjustment request includes: the voice group call is adjusted to the information of the visual group call.
Specifically, the base station to which the terminal belongs interacts with the respective terminal according to the adjustment request, and adjusts the voice group call to a visual group call.
The adjustment request may include: the group Call Type (Call Type) and corresponding media information. The base station interacts with the terminal according to the adjustment request, for example, the base station sends a Group Call resource adjustment setting message (Group Call Config) to the terminal. For example, the cluster core network element sends the adjustment request to notify the base station side to modify the group context, so as to adjust to establish a new group resource bearer for the video of the visual type. And updating a Group Call Setup Indication (Group Call Setup Indication) of the NAS message stored at the base station side, wherein a Group Resource List (Group Resource List) in the message comprises Group resources (Group resources), so that the Group Resource List simultaneously carries media information of voice and video, and the Group Call type is changed from voice Group Call to visual Group Call. Namely, the group calling type is changed from voice group calling to homologous visual group calling.
In practical application, the base station may send a group call resource adjustment setting message to the terminal through the air interface, for notifying the terminal of corresponding group call resource modification, where the group call resource adjustment setting message carries an updated NAS message group call setting instruction.
In this embodiment, as a supplement to the standard, a solution when the group call type of the currently ongoing group call service is inconsistent with the group call type corresponding to the group call type identifier requested by the scheduling station is provided, specifically, the group call type of the currently ongoing group call service is a voice group call, and the group call type identifier is a solution when the group call type identifier is a visual group call identifier.
In yet another alternative embodiment of the present invention, after step 105 of the method, the method may further include step 106, not shown in the figure:
106. and the cluster core network element takes the media parameters carried in the establishment request as the media parameters of the adjusted group call service.
Correspondingly, an SIP response for notifying the establishment of the group call service is sent to the dispatching desk, the response content is that the group call service is allowed to be added, and the response carries the speaking right authorization information. Optionally, the response may further include: media plane information of a core network, a pttaccept extended header field carried by the core network, and the like.
For example, after the trunking core network element determines the media parameters, a response allowing the group call group to join, an SIP (200OK) message, is sent to the dispatch station to notify that the group call is successfully established, and the response carries information such as the speaking right authorization information, the media plane information of the core network, and the received service (pttaccept) extension header field.
Further, the dispatching station sends an SIP Acknowledgement (ACK) message to the trunking core network element to confirm that the current group call is successfully established.
Specifically, step 101, step 102 and step 105 are described as a complete method embodiment. Alternatively, step 101, step 102, step 105 and step 106 are one complete method embodiment.
In this embodiment, as a supplement to the standard, a solution for adjusting the media parameters after adjusting the group call type of the currently ongoing group call service to the group call type corresponding to the group call type identifier requested by the scheduling station is provided.
In a fourth alternative embodiment of the present invention, after step 102 of the above method, the method further comprises step 107, not shown in the figure:
107. if the cluster core network element determines that the group calling group is carrying out the group calling service, but the group calling type of the group calling service is not consistent with the group calling type corresponding to the group calling type identifier in the establishment request, the cluster core network element sends a response allowing to join the group calling group to the dispatching desk when the group calling type of the current carrying group calling service is a visual group calling and the group calling type identifier is a voice group calling identifier, and the response carries speaking right authorization information.
That is to say, the network element of the trunking core network respectively checks the group call type of the group call service and the group call type corresponding to the group call type identifier in the establishment request. When the group call type is not consistent, for example, the group call type of the currently ongoing group call service is a visual group call, and the group call type identifier is a voice group call identifier, the trunking core network element sends a response allowing to join the group call to the dispatching desk.
Specifically, step 101, step 102, and step 107 are one embodiment of the method.
In this embodiment, as a supplement to the standard, a solution when the group call type of the currently ongoing group call service is inconsistent with the group call type corresponding to the group call type identifier requested by the scheduling station is provided, specifically, the group call type of the currently ongoing group call service is a visual group call, and the group call type identifier is a solution when the voice group call identifier.
In a fifth alternative embodiment of the present invention, before step 103 of the above method, the method further comprises step 108, not shown in the figure:
108. if the speaking right terminal exists in the ongoing group calling service, sending speaking right releasing information to the speaking right terminal and the base station to which the speaking right terminal belongs, so that the base station and the speaking right terminal interactively release the speaking right of the speaking right terminal.
That is, the network element of the cluster core network checks the ongoing group call service condition, and if no speaking right terminal exists at present, the network element sends a response allowing to join the group call group to the dispatching station, wherein the response carries the speaking right authorization information.
Specifically, if a speaking right terminal exists at present, a speaking right release message is sent to a base station to which the speaking right terminal belongs, so that the base station and the speaking right terminal interactively release the speaking right of the speaking right terminal.
In the embodiment, as a supplement to the standard, a solution is provided when the speaking right terminal exists in the currently ongoing group call service.
Of course, after steps 106 and 107, step 108 described above may also be performed.
Accordingly, after performing 108, the above-mentioned cluster core network element may also transmit a NAS message for explaining the speaking right status indication information to all terminals in the group call group.
Specifically, after the cluster core network element authorizes the speaking right of the dispatching desk, the cluster core network element sends an NAS message to the base stations to which all terminals in the group calling group belong, so that the base stations and the terminals interactively explain that the current speaking right state is changed.
In the present embodiment, a solution for changing the speaking right status is proposed as a supplement to the standard.
In summary, the method for a dispatching desk to join a group call in the embodiment of the present invention at least performs the following four aspects on the standard:
firstly, a scheduling station requests to establish a flow description of a group calling service: in the process of maintaining the group calling service, the dispatching station re-issues the group calling service to the group calling, and after the cluster core network element determines that the group calling group corresponding to the current group calling type is carrying out the group calling service, the cluster core network element sends a response allowing the group calling group to be added to the dispatching station.
Secondly, default authorization: in the process of maintaining the group calling service, the dispatching station re-issues the group calling service to the group calling, the user priorities of the dispatching station, the group calling party and the speaking right terminal are not matched, and the speaking right is authorized to the dispatching station by default.
Thirdly, changing the call type: for the ongoing voice group call service, the dispatching station initiates a visual group call to the group call, the cluster core network expands the original voice group call to the visual group call, and the video media parameters are subject to the parameters requested by the dispatching station.
Fourthly, determining audio and video media parameters: in the ongoing voice group call service, the dispatching desk initiates the voice group call service to the group call, and the media parameters in the call are used as the standard whether the media parameters are the same or not; in the ongoing visual group call service, the dispatching desk initiates visual group call with other video resolution and frame rate, or initiates voice group call, the call type is maintained, and the trunking core network is subject to the ongoing call media parameters.
