Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and 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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
In the embodiments of the application, a user attribution cluster control function body, referred to as a user H-TCF for short; a group affiliation cluster control function, referred to as group G-TCF for short; a source group home cluster control function, which may be referred to as a source group G-TCF for short; the non-source group home cluster control function is a member group other than the source group, also referred to as a non-source group G-TCF. The called group is usually used as a source group, and in some special scenarios, one source group can be selected according to a specific strategy.
Fig. 1 is a block dispatching implementation method of a digital trunking system according to an embodiment of the present disclosure. The method comprises the following steps:
step 101: at least 2 groups are dispatched together to form a dispatched group.
Generally, the method allows the number of dispatch groups and the number of member groups per dispatch group to be limited only by the overall call processing capabilities of the home cluster control function (i.e., TCF).
The dispatching desk dispatches a plurality of groups together to form a dispatching group, and the groups can belong to the same trunking control function body or different trunking control function bodies. The dispatch group information is recorded to the cluster subscription data management.
Step 102: and any terminal of the dispatch group initiates a group call request, and the source group attribution cluster control function body establishes the group call.
The source group home cluster control function is the source group G-TCF. Taking a group member visiting a foreign place (visited place trunking function control body is called V-TCF for short) to initiate a call as an example, a call initiating message is sent to a user attribution trunking control function body H-TCF of a caller by the V-TCF, and then is sent to a called group attribution trunking control function body by the user attribution trunking control function body H-TCF. When the called group affiliation cluster control function body obtains the group calling authorization information, the called group affiliation cluster control function body is informed that the group is dispatched and connected and the specific dispatching member group number information.
It should be noted that in some special scenarios, a source group may be selected according to a specific policy. For example, when a dispatching desk or group member calls a certain dispatching member group, some member groups are already in the call before being dispatched and the call is continued until the call is not finished; or some group is first dispatched and called and a member group is later joined to the dispatch group and also called.
Step 103: and the source group attribution cluster control function body sends a call starting request to the non-source group attribution cluster control function body.
The non-source group is the remaining group except the source group, which is the non-source group G-TCF, to which the cluster control function belongs.
Further, any terminal in the dispatch group initiates a group call request, and each group is activated. That is, the dispatcher station or the group member terminal initiates the call to any one of the dispatched group of members, and all the members of the dispatched group need to be activated.
The source group attribution trunking control function is responsible for establishing the group call and also responsible for sending an originating call request to the non-source group attribution trunking control function, and a mark is needed in the originating call request to indicate that the group is originated because other member groups of the dispatching group are called, so that the other member groups can not send the originating call request in a recycling mode.
Step 104: the non-source group home cluster control function activates the local group.
The non-source group attribution cluster control function body is responsible for establishing the call of the group after receiving the call starting request sent by the source group attribution cluster control function body, and simultaneously, tells the call establishment result to the source group attribution cluster control function body.
Step 105: and any terminal of the dispatch group applies or releases the speaking right.
The final coordination work of the speaking right is responsible for the cluster control function body belonging to the source group.
Furthermore, in one dispatch group, only one terminal is allowed to obtain the talk right at the same time, and the speech of the terminal obtaining the talk right is forwarded to all listening users in the dispatch group.
The voice/video media stream of the group call is dispatched and forwarded to the group affiliation cluster control function body via the source group affiliation cluster control function body, and the group affiliation cluster control function body is responsible for forwarding to the members in the group.
If the members of the source group are speakers, the source group home cluster control function directly forwards the media stream to each group home cluster control function. If the member of the non-source group is the speaker, the member group attribution trunking control function body sends the media stream to the source group attribution trunking control function body, and the source group attribution trunking control function body sends the media stream to other non-speaking-right member group attribution trunking control function bodies.
The following steps 106-108 are embodiments of the source group home cluster control function performing speaking right coordination.
Step 106: the non-source group attribution cluster control function body preprocesses the speaking right application or release and automatically judges the granting, refusing or releasing of the speaking right.
Each non-source group attribution trunking control function body preprocesses the speaking right application request and decides whether to grant the speaking right or reject the speaking right application.
Step 107: the dispatching station/terminal successfully applies or releases the speaking right, starts or ends speaking, and the non-source group attribution cluster control function body informs the source group attribution cluster control function body of the speaking right change information.
At this time, the dispatcher station/terminal applies or releases the talk right successfully, and can start or end talking. Meanwhile, the non-source group attribution cluster control function body informs the source group attribution cluster control function body of the speech right change information, the source group attribution cluster control function body determines whether to inform each group attribution cluster control function body to modify the speech right information or not according to the speech right state recorded by the source group attribution cluster control function body, and the speech right application group attribution cluster control function body can also modify the speech right preprocessing result of the source group attribution cluster control function body according to the speech right information of the source group attribution cluster control function body.
Step 108: and the source group attribution cluster control function body determines whether to inform the non-source group attribution cluster control function body to modify the speech right information or not according to the recorded speech right state.
The specific steps of speaking right coordination are as follows:
the affiliation cluster control function body of each member group records the current speaking right idle/occupation state of the dispatching group and the speaking right priority information of the current speaking right user in the speaking right occupation state, and is used for judging whether the member group can acquire the speaking right.
The member group dispatching station/group member applies for the speaking right, requests to be sent to the caller attribution trunking control function body by the V-TCF, and then is sent to the group attribution trunking control function body by the user attribution trunking control function body, the group attribution trunking control function body judges whether the group member can grant the speaking right according to the locally recorded speaking right idle/occupation state of the group dispatching and receiving and the speaking right priority information: if the current speaking right is free, directly granting the speaking right; if the current speaking right is occupied and the priority of the current speaking right user is higher than or equal to that of the user who newly applies for the speaking right, the speaking right is not granted; if the current speaking right is occupied but the priority of the current speaking right user is lower than that of the user who applies for the new speaking right, the user who applies for the new speaking right can seize the speaking right of the current speaking right user.
When the local talk right state or the talk right user information changes, the non-source member group needs to inform the source group home cluster control function body. The source group attribution cluster control function body judges whether to accept the speech right change of the non-source member group according to the currently recorded speech right state and the speech right member priority: if the speaking right is released, the speaking right is accepted; if the call right application is available, the principle of judging whether to grant the call right to the non-source group member is the same as the cluster control function body of the non-source group attribution. If the source group attribution cluster control function body judges that the speaking right state of the dispatching group changes or the speaking right user information changes, the speaking right notification needs to be sent to each non-source group attribution cluster control function body, and each member group attribution cluster control function body is responsible for notifying the members in the group. For the non-source group attribution cluster control function body which actively sends the speaking right notification message to the source group attribution cluster control function body, the processing principle is as follows: if the source group attribution trunking control function body receives the talk right change of the non-source group, the talk right notification message does not need to be sent to the non-source group which sends the talk right change again; if the source group ascription cluster control function rejects the change of the speaking right of the non-source group, which may be caused by the reason that the speaking right information of the non-source group ascription cluster control function is out of step with the source group ascription cluster control function, or the inconsistency caused by applying speaking rights of a plurality of member groups simultaneously, the source group ascription cluster control function needs to send a speaking right notification message to the non-source group ascription cluster control function again, the non-source group ascription cluster control function sends a speaking right prompt to the members of the group again according to the speaking right notification message, if the group records that the members in the group successfully apply for the speaking right before and the speaking party number carried in the speaking right notification message sent by the source group ascription cluster control function is not the member of the speaking right recorded by the group, the flow of releasing the group members is also needed to initiate.
The member group dispatching station/group member applies for releasing the speech right, or the user or group calling control judges that the user has a very long speech time and needs to forcibly release the speech right, the member group attribution trunking control function firstly processes the speech time, then the source group attribution trunking control function informs the source group attribution trunking control function and then informs other member group attribution trunking control functions. The control function body of the affiliation cluster of each member group is responsible for informing the change of the speaking right of the members in the group.
Step 109: and any terminal of the dispatch group initiates a group call ending request.
It should be noted that, when any terminal in the dispatch group initiates a group call ending request, each group releases the call.
The following steps 110 to 111 are embodiments of the source group home cluster control function performing group call ending coordination.
Step 110: the non-source group home cluster control function autonomously decides whether to allow the call to be released or not and informs the source group home cluster control function.
The control of group calling release is that firstly the non-source group attribution cluster control function body decides whether to allow releasing the calling, then the source group attribution cluster control function body is informed, and then the source group attribution cluster control function body informs other member group attribution cluster control function bodies to release the calling.
Step 111: the source group home cluster control function informs the other non-source group home cluster control functions to release the call.
The specific method comprises the following steps:
if the source group member initiates a call release request, the release request is through the member currently visiting the cluster control function- > user attribution cluster control function- > group attribution cluster control function, the source group attribution cluster control function needs to inform other non-source group attribution cluster control functions to release the non-source group call besides controlling the group call release of the group. If the non-source group member initiates a call release request, the release request is through V-TCF- > user attribution cluster control function- > group attribution cluster control function, the non-source group attribution cluster control function controls the group call release of the group, and the non-source group attribution cluster control function also needs to inform the source group attribution cluster control function of the group call release request; the source group home cluster control function not only releases the call of its own group, but also needs to inform other non-source group home cluster control functions to release other member group calls, and at this time, the group call is ended.
The group assignment implementation method provided in the embodiment of the present application further includes sending, by the cluster subscription data management, newly added assignment group subscription information to the cluster control function body to which each group belongs.
The task of notifying the group assignment subscription data to the group affiliation cluster control function body can also be completed by the user affiliation cluster control function body of the dispatching desk, and the group assignment subscription data is obtained from the cluster subscription data management only when the group affiliation cluster control function body is restarted. Meanwhile, pushing the group assignment subscription data to the group affiliation trunking control function in advance is only a preferred method of the B-Trunc architecture, and is not necessary, and it is possible that the data subscription data management and the group affiliation trunking control function are integrated under other system architectures, or the group affiliation trunking control function itself does not store various subscription information, and the data subscription data management will request various subscription information only when a call occurs.
In step 101, it is not necessary to record group assignment subscription data in the group subscription data management, for example, group assignment activated for multiple calls, and it is only necessary for the current call to assign the groups together, and it is not necessary to record group assignment subscription data in the group subscription data management.
It should be noted that, in the embodiment of the present invention, each home Trunking Control Function (TCF) uses an extended SIP message interaction, and can be conveniently converted into other message protocols in actual use.
The implementation method for group dispatch and connection of the digital trunking system provided by the embodiment is simple, does not need to modify a base station and a terminal, and can realize the functions of simultaneous called of each member group, the coordination of the speaking right among the member groups and the release of the member group calling only by operating software; meanwhile, the number of the allowed dispatch groups and the number of the member groups in each dispatch group are not particularly limited and are only limited by the overall call processing capacity.
Fig. 2 is another implementation method of group assignment of the digital trunking system.
The main difference between the group dispatch implementation method and the method shown in fig. 1 is the speaking right coordination mode and the call ending mode.
Step 201: at least 2 groups are dispatched together to form a dispatched group.
Generally, the method allows the number of dispatch groups and the number of member groups per dispatch group to be limited only by the overall call processing capabilities of the home cluster control function.
The dispatching desk dispatches a plurality of groups together to form a dispatching group, and the groups can belong to the same group attribution cluster control function body or different group attribution cluster control function bodies. The dispatch group information is recorded to the cluster subscription data management.
Step 202: and any terminal of the dispatch group initiates a group call request, and the source group attribution cluster control function body establishes the group call.
The source group is called group for short, the source group attribution cluster control function body is source group attribution G-TCF. Taking a group member that visits a foreign place (V-TCF for short) to initiate a call, the call initiation message is sent from the visiting cluster function controller where the user is currently located to the user belonging cluster control function H-TCF of the caller, and then sent from the user belonging cluster control function H-TCF to the called group belonging cluster control function G-TCF. When the called group affiliation cluster control function body obtains the group calling authorization information, the called group affiliation cluster control function body is informed that the group is dispatched and connected and the specific dispatching member group number information.
It should be noted that in some special scenarios, a source group may be selected according to a specific policy. For example, when a dispatcher or group member calls a certain group of members to be dispatched, some group of members are already in the call before being dispatched and the call continues until the time is not finished; or some group is first dispatched and called and a member group is later joined to the dispatch group and also called.
Step 203: and the source group attribution cluster control function body sends a call starting request to the non-source group attribution cluster control function body.
The non-source group is the remaining group except the source group, and the non-source group attribution cluster control function, i.e. the non-source group attribution G-TCF.
Further, any terminal in the dispatch group initiates a group call request, and each group is activated. That is, the dispatcher station or the group member terminal initiates the call to any one of the dispatched group of members, and all the members of the dispatched group need to be activated.
The source group attribution trunking control function is responsible for establishing the group call and also responsible for sending an originating call request to the non-source group attribution trunking control function, and a mark is needed in the originating call request to indicate that the group is originated because other member groups of the dispatching group are called, so that the other member groups can not send the originating call request in a recycling mode.
Step 204: the non-source group home cluster control function activates the local group.
The non-source group attribution cluster control function body is responsible for establishing the call of the group after receiving the call starting request sent by the source group attribution cluster control function body, and simultaneously, tells the call establishment result to the source group attribution cluster control function body.
Step 205: and any terminal of the dispatch group applies or releases the speaking right.
The final coordination work of the speaking right is responsible for the cluster control function body belonging to the source group.
Furthermore, in one dispatch group, only one terminal is allowed to obtain the talk right at the same time, and the speech of the terminal obtaining the talk right is forwarded to all listening users in the dispatch group.
The voice/video media stream of the group call is dispatched and forwarded to each group affiliation cluster control function body through the source group, and each group affiliation cluster control function body is responsible for forwarding to the members in the group.
If the members of the source group are speakers, the source group home cluster control function directly forwards the media stream to each group home cluster control function. If the member of the non-source group is the speaker, the member group attribution trunking control function body sends the media stream to the source group attribution trunking control function body, and the source group attribution trunking control function body sends the media stream to other non-speaking-right group attribution trunking control function bodies.
The following steps 206-208 are embodiments of the source group home cluster control function performing session right coordination.
Step 206: and the non-source group attribution cluster control function body sends application or release speech right information to the source group attribution cluster control function body.
The speaking right application and speaking right release are processed by the source group attribution trunking control function body, and the non-source group attribution trunking control function body processes the speaking right application and speaking right release and sends information to the source group attribution trunking control function body.
Step 207: the source group attribution cluster control function body processes whether to grant, reject or release the speaking right in a unified way and informs the non-source group attribution cluster control function body of the speaking right change information.
This step differs from the method shown in fig. 1 in that the floor application/floor release is strictly controlled by the source group home cluster control function. The source group attribution trunking control function judges whether the talk right is granted or not and allows the talk right to be released, and then notifies the processing result to the group attribution trunking control function which sends the request. If the call right information of the sending group changes, the source group attribution cluster control function body is responsible for informing the attribution cluster control function body of each member group.
The process that the source group affiliation cluster control function notifies each member group affiliation cluster control function of the change of the talk right, and each member group affiliation cluster control function is responsible for notifying the information of the talk right of the members in the group is the same as the method described in fig. 1.
Step 208: the right of speech is applied or released successfully, and the speech is started or ended.
Step 209: and any terminal of the dispatch group initiates a group call ending request.
It should be noted that, when any terminal in the dispatch group initiates a group call ending request, each group releases the call.
The following steps 210-211 are embodiments of the source group home cluster control function performing group call ending coordination.
Step 210: after receiving the group call ending request, the non-source group attribution trunking control function body forwards the group call ending request information to the source group attribution trunking control function body.
Step 211: the source group attribution cluster control function body uniformly controls whether to allow the call to be released or not, and informs the non-source group attribution cluster control function body of the call releasing information to release the call.
And the source group attribution cluster control function body judges whether the group calling is allowed to be released, and informs the member group attribution cluster control function body to release the calling. At this point the group call ends.
This step differs from the method of fig. 1 in that whether the release call is allowed to be controlled by the source group home cluster control function in a unified manner, and the rest of the processing method is the same as the method described in fig. 1.
The digital trunking system group dispatching and receiving implementation method provided by the embodiment of the application is simple, base stations and terminals do not need to be modified, and functions of simultaneous calling of all member groups, session right coordination among the member groups and member group call release can be realized only through operation software.
FIG. 3 is a flow chart of dispatching station group.
The flow chart shown in the figure takes the digital trunking system group dispatch implementation method shown in fig. 1 as an example. The implementation steps are as follows:
the dispatching desk selects several groups (at least two groups) to be dispatched to carry out group dispatching operation, and sends a group dispatching request message to the home H-TCF of the dispatching desk, wherein the group dispatching request message carries information such as the name of a dispatching group and the number of each dispatching member group;
the dispatching station attribution H-TCF sends the group dispatching request to the cluster signing data management THSS;
cluster signing data management THSS judges the validity of the group dispatching request, and if the group dispatching request is legal, the cluster signing data management THSS records group dispatching signing data; the cluster subscription data management THSS returns a group dispatching response message to the H-TCF;
H-TCF returns the group to dispatch and answer the message to the control desk;
the cluster subscription data management THSS sends group assignment data push request information (which must include the group number of each member group or other unique identifier of the member group) to each assigned member group belonging cluster control function, so that the group belonging cluster control function joins other member groups into a call according to the group assignment subscription information when the scheduling station/terminal initiates a group call;
and the member group affiliation cluster control function body returns a group dispatch data push response to the cluster subscription data management THSS respectively.
Fig. 4 is a flowchart of the work of the control function of the group affiliation cluster when initiating a group call.
The flow chart shown in the figure takes the digital trunking system group dispatch implementation method shown in fig. 1 as an example. The implementation steps are as follows:
the dispatching desk/cluster terminal as group member initiates group calling, the group calling request is through caller V-TCF- > caller H-TCF- > group G-TCF, the source group G-TCF judges that the group is dispatched and received, then the G-TCF not only continues to process the call of the called group, but also needs to send call establishment request to other member groups dispatched and received as a group to the called group, wherein the dispatching desk/cluster terminal carrying the caller as the originating call, the called as the dispatching and receiving member group carry a mark to indicate that the group is called because other member groups of the dispatching and receiving group are called;
the member group attribution cluster control function body receives the call request message and directly returns a call establishment response;
the member group belonging cluster control function body judges that the self group is called because other member groups of the dispatching group are called, and does not need to judge whether the calling party allows to call the called group or not, does not need to send a message to other dispatching member groups, and only needs to be responsible for activating the group call. The member group attribution cluster control function body judges that the call is successfully established, and sends a call establishment success notice to the source group attribution cluster control function body;
the source group attribution cluster control function body returns a call establishment success notification response to the member group attribution cluster control function body;
the source group attribution cluster control function body judges that the call is successfully established, and the calling user acquires the speaking right to start speaking.
