Wherein, the speaking right notification information includes the cluster user terminal identification authorized by the speaking right.
The cluster control center sends speaking right notification information to other cluster control centers of the cluster group, the speaking right notification information comprises cluster user terminal identification authorized by speaking right, after receiving the speaking right notification information, the other cluster control centers forward the speaking right notification information to the cluster user terminals subordinate to the cluster control center, and modify the recorded current cluster speaking right state into an occupied state, and record the cluster control center sending the speaking right notification information as a group anchor cluster control center. The current group speaking right states recorded by all the cluster control centers in the cluster group are kept consistent.
Preferably, the sending of the speaking right notification information to the other cluster control centers of the cluster group is:
and sending speaking right notification information of preset times to other cluster control centers of the cluster group.
The success rate of sending can be improved by sending the speaking right notification information of the preset times to other cluster control centers of the cluster group.
Based on the above embodiment, after establishing the trunking group call, the trunking control center may directly grant the speaking right to the trunking user terminal when determining that the current group speaking right state is the idle state according to the speaking right application request included in the call establishment request or the speaking right application request initiated by the subordinate trunking user terminal, and record itself as the group anchor trunking control center, and it is not necessary to route the speaking right application request to the fixed group anchor trunking control center, thereby reducing the speaking right application delay when the speaking right is idle.

EXAMPLE III
Fig. 3 is a flowchart of a calling method for a multi-cluster control center cluster group according to a third embodiment of the present invention, which is optimized based on the foregoing embodiments, and further adds a processing operation when a group anchor cluster control center receives a talk right application request when a current group talk right state is an occupied state, where the method specifically includes the following steps:
step 310, receiving the information of the cluster group sent by the cluster scheduling center.
Step 320, according to the call establishment request initiated by the subordinate cluster user terminal, determining to establish the cluster group call when the call is not established, and according to the information of the cluster group, sending the call establishment request to other cluster control centers of the cluster group, so as to request other cluster control centers to send the call establishment request to the subordinate cluster user terminal, so that the cluster user terminals of other cluster control centers join in the cluster group call.
Step 330, according to the speaking right application request included in the call establishment request or the speaking right application request initiated by the subordinate trunking user terminal, when the current group speaking right state is determined to be the idle state, the speaking right of the trunking user terminal initiating the speaking right application request is granted, the current group speaking right state is modified to be the occupied state, and the current group speaking right state is recorded as the group anchor trunking control center.
Step 340, sending speaking right notification information to other cluster control centers of the cluster group to instruct other cluster control centers to forward the speaking right notification information to subordinate cluster user terminals, modifying the speaking right state of the current group to be an occupied state, and recording the cluster control center sending the speaking right notification information as a group anchor cluster control center.
Step 350, when the current group speaking right state is the occupied state, after receiving the speaking right application request of the cluster user terminal, queuing the cluster user terminal according to the speaking right grade in the speaking right application request and the time stamp of speaking right application.
The speaking right application request comprises a cluster user terminal identification, a speaking right grade and a speaking right application timestamp.
When the current group talk right state recorded by the cluster control center in the cluster group is an occupied state, no matter which cluster user terminal subordinate to the cluster control center in the cluster group applies for the talk right, the talk right application request is routed to the group anchor cluster control center through the cluster control center to which the cluster user terminal belongs.
When the current group speaking right state is an occupied state, the group anchor cluster control center queues the cluster user terminals applying the speaking right according to the speaking right grade in each received speaking right application request and the time in the timestamp of the speaking right after receiving the speaking right application request of the cluster user terminals under the group anchor cluster control center or the speaking right application requests of the cluster user terminals under the other cluster control centers, the cluster user terminals applying the speaking right are ranked in front of the cluster user terminals applying the speaking right with the high speaking right grade, and the cluster user terminals applying the speaking right with the early speaking right grade are ranked in front of the cluster user terminals applying the speaking right with the same speaking right grade.
And step 360, after receiving the speaking right release request of the speaking right authorizing party, authorizing the speaking right to the first cluster user terminal in queue.
After receiving the speech right release request of the speech right authorizing party, the group anchor cluster control center authorizes the speech right to the first cluster user terminal in queue, if the cluster control center to which the first cluster user terminal in queue belongs is not the group anchor cluster control center, the group anchor cluster control center sends the speech right authorizing information of the first cluster user terminal in queue to the cluster control center to which the group anchor cluster control center belongs, the cluster control center to which the group anchor cluster control center belongs forwards the first cluster user terminal in queue, sends speech right notification information to the cluster user terminals under the cluster control center of the group anchor cluster control center, simultaneously sends speech right notification information to other cluster control centers, and the other cluster control centers forwards the speech right notification information to the cluster user terminals under the cluster control center. The speaking right authorizer is the cluster user terminal to which the speaking right is currently granted.
According to the technical scheme, on the basis of the embodiment, when the current group talk right state is the occupied state, the group anchor cluster control center queues the cluster user terminals applying the talk right according to the talk right level in the talk right application request and the timestamp applying the talk right after receiving the talk right application request, and authorizes the talk right to the first cluster user terminal after receiving the talk right release request of the talk right authorizer, so that the talk right is authorized to the cluster user terminals with high talk right level or the same talk right level but earlier application time when the talk right is released, and the granting of the talk right is well-ordered.
Example four
Fig. 4 is a flowchart of a calling method of a multi-cluster control center cluster group according to a fourth embodiment of the present invention, which is optimized based on the foregoing embodiment, and further adds an operation process when a talk right authorizer releases a talk right and there is no cluster user terminal with a talk right queue, where the method specifically includes the following steps:
step 410, receiving the information of the cluster group sent by the cluster scheduling center.
Step 420, according to the call establishment request initiated by the subordinate cluster user terminal, determining that the cluster group call is established when the call is not established, and according to the information of the cluster group, sending the call establishment request to other cluster control centers of the cluster group to request other cluster control centers to send the call establishment request to the subordinate cluster user terminal, so that the cluster user terminals of other cluster control centers join in the cluster group call.
Step 430, according to the speaking right application request included in the call establishment request or the speaking right application request initiated by the subordinate trunking user terminal, when the current group speaking right state is determined to be the idle state, the speaking right of the trunking user terminal initiating the speaking right application request is granted, the current group speaking right state is modified to be the occupied state, and the current group speaking right state is recorded as the group anchor trunking control center.
Step 440, sending speaking right notification information to other cluster control centers of the cluster group to instruct other cluster control centers to forward the speaking right notification information to subordinate cluster user terminals, modifying the speaking right state of the current group to be an occupied state, and recording the cluster control center sending the speaking right notification information as a group anchor cluster control center.
Step 450, after receiving the talk right release request of the talk right authorizer, if there is no trunking user terminal with talk right queuing, modifying the current group talk right state to an idle state, deleting the record of the local group anchor trunking control center, sending the talk right idle information to other trunking control centers, and instructing other trunking control centers to modify the current group talk right state to an idle state and delete the information of the local group anchor trunking control center.
When the group anchor cluster control center receives the speech right release request of the speech right authorizing party, the speech right of the speech right authorizing party is released, whether a cluster user terminal with speech right queuing exists is judged, if no cluster user terminal with speech right queuing exists, the current cluster speech right state is modified into an idle state, the record of the local group anchor cluster control center is deleted, namely the cluster control center is no longer the group anchor cluster control center, the speech right idle information is sent to other cluster control centers in the cluster group, after the other cluster control centers receive the speech right idle information, the current group speech right state stored locally is modified into the idle state, and the information of the locally recorded group anchor cluster control center is deleted.
Based on the above embodiment, after receiving a talk right release request from a talk right authorizer, the group anchor cluster control center modifies the current group talk right state into an idle state when confirming that there is no cluster user terminal with a talk right queue, deletes the record of the local group anchor cluster control center, sends the talk right idle information to other cluster control centers, keeps the talk right states of the cluster control centers consistent, and does not have the group anchor cluster control center in an idle state, and records itself as the group anchor cluster control center only when receiving a talk right application request from a subordinate cluster user terminal.
On the basis of the above technical solution, it is preferable to further include:
after the current group speaking right state is modified into an idle state, a speaking right idle timer is started;
and if the speaking right idle timer is overtime, sending a call release message to the subordinate cluster user terminal.
After the current group talk right state is modified into the idle state by each cluster control center in the cluster group, the talk right idle timer is started, and after the talk right idle timer is overtime, each cluster control center releases the cluster group call of the control center, so that the waste of resources is avoided.
EXAMPLE five
Fig. 5 is a flowchart of a calling method for a multi-cluster control center cluster group according to a fifth embodiment of the present invention, which is optimized based on the foregoing embodiment, and further adds a process of a service conflict of authorized speaking right of a plurality of cluster user terminals, where the method specifically includes the following steps:
step 510, receiving information of the cluster group sent by the cluster scheduling center.
Step 520, according to the call establishment request initiated by the subordinate cluster user terminal, determining that the cluster group call is established when the call is not established, and according to the information of the cluster group, sending the call establishment request to other cluster control centers of the cluster group to request other cluster control centers to send the call establishment request to the subordinate cluster user terminal, so that the cluster user terminals of other cluster control centers join in the cluster group call.
Step 530, according to the speaking right application request included in the call establishment request or the speaking right application request initiated by the subordinate trunking user terminal, when the current group speaking right state is determined to be the idle state, the speaking right of the trunking user terminal initiating the speaking right application request is granted, the current group speaking right state is modified to be the occupied state, and the current group speaking right state is recorded as the group anchor trunking control center.
And 540, sending speaking right notification information to other trunking control centers of the trunking group to instruct other trunking control centers to forward the speaking right notification information to subordinate trunking user terminals, modifying the speaking right state of the current group to be an occupied state, and recording the trunking control center sending the speaking right notification information as a group anchor trunking control center.
Step 550, after speaking right authorization is carried out to subordinate cluster user terminals, when speaking right notification information of other cluster control centers of the cluster group is received, comparing speaking right grade and speaking right authorization time of each authorized cluster user terminal, if the speaking right grade of the subordinate cluster user terminals is lower or the speaking right grade is the same as the authorization time, canceling the speaking right of the subordinate cluster user terminals, sending speaking right preemption information to the subordinate cluster user terminals, sending the speaking right notification information of other cluster control centers to the other cluster user terminals subordinate to the cluster control center, and recording that the cluster control center sending the speaking right notification information is the group anchor cluster control center.
Wherein the speaking right notification message further comprises: the user talk burst level and the talk burst grant timestamp.
The trunking user terminals belonging to different trunking control centers all initiate call establishment requests or apply for the speech right when the speech right is idle in a smaller time interval, and because the trunking control centers to which the trunking control centers belong all judge that the current group speech right state is idle, the speech right of the trunking user terminals can be granted, thereby causing service conflict.
When the cluster hole center which has performed speaking right authorization to the subordinate cluster user terminal receives speaking right notification information of other cluster control centers, the cluster control center compares the speaking right grade of each authorized cluster user terminal with the speaking right authorization time in the speaking right authorization timestamp according to the speaking right communication information, if the cluster control center judges that the speaking right level of the cluster user terminal authorized by the cluster control center is lower, or the speaking right level of the cluster user terminals authorized by other speaking rights is the same but the authorized time is later, the cluster control center cancels the speaking right of the cluster user terminal authorized by itself, sends speaking right seizing information to the cluster user terminal, sending the new speaking right authorizing party message, namely the speaking right informing message received by other cluster control centers, to other cluster user terminals subordinate to the cluster control center, and recording that the cluster control center sending the speaking right informing message is the group anchor cluster control center; if the cluster control center judges that the speaking right grade of the cluster user terminal authorized by the cluster control center is higher, or the speaking right grade of the cluster user terminal authorized by the cluster control center is the same as that of other cluster user terminals authorized by the speaking right but the authorization time is earlier, the speaking right of the cluster user terminal authorized by the cluster control center is reserved. And the other cluster user terminals are the cluster user terminals except the cluster user terminal which cancels the speaking right under the cluster control center.

step 610, receiving the information of the cluster group sent by the cluster scheduling center.
Step 620, according to the call establishment request initiated by the subordinate cluster user terminal, determining that the cluster group call is established when the call is not established, and according to the information of the cluster group, sending the call establishment request to other cluster control centers of the cluster group to request other cluster control centers to send the call establishment request to the subordinate cluster user terminal, so that the cluster user terminals of other cluster control centers join in the cluster group call.
Step 630, according to the speaking right application request included in the call establishment request or the speaking right application request initiated by the subordinate trunking user terminal, when the current group speaking right state is determined to be the idle state, the speaking right of the trunking user terminal initiating the speaking right application request is granted, the current group speaking right state is modified to the occupied state, and the current group speaking right state is recorded as the group anchor trunking control center.
Step 640, sending a speaking right notification message to other trunking control centers of the trunking group to instruct other trunking control centers to forward the speaking right notification message to subordinate trunking user terminals, modify the speaking right state of the current group to be an occupied state, and record the trunking control center sending the speaking right notification message as a group anchor trunking control center.
Step 650, after receiving the call release request, when determining that the trunking user terminal initiating the call release request has the right to release the group call, deleting the record of the group anchor trunking control center, sending the call release message to the subordinate trunking user terminals, and sending the call release message to other trunking control centers to instruct the other trunking control centers to forward the call release message to the subordinate trunking user terminals.
When the group anchor cluster control center receives the call release request, it judges whether the cluster user terminal initiating the call release request has the right to release the group call, if the cluster user terminal initiating the call release request has the right to release the group call, it deletes the record of the local group anchor cluster control center, sends the call release message to the subordinate cluster user terminal and sends the call release message to other cluster control centers, after receiving the call release message, the other cluster control centers forward to the subordinate cluster user terminals, thus releasing the cluster group call.
Before deleting the record of the group anchor cluster control center, the method preferably further includes:
and sending a speaking right release message to the current speaking right party.
When the group anchor cluster control center determines that the cluster user terminal initiating the call release request has the right to release the group call, the group anchor cluster control center firstly sends a talk right release message to the current talk right party to inform the current talk right party to release the talk right, and then releases the cluster group call, thereby avoiding directly cutting off the voice of the current talk right party.
The technical solution of this embodiment provides a process after the group anchor cluster control center receives the call release request, and releases the cluster group call when the cluster user terminal initiating the call release request has the right to release the group call.
