Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The core idea of the invention is as follows: the dispatching desk establishes the group calling of any plurality of groups through a conversation request, so, a new group does not need to be established, the establishment of the merged group calling can be simply and quickly realized, and the success probability of the merged group calling is improved.
Fig. 1 is a flowchart illustrating a first embodiment of the present invention, and as shown in fig. 1, the method for establishing a merged group call implemented in this embodiment mainly includes:
In this step, the dispatching desk needs to send a merged group call establishment request to the core network, and informs all groups participating in the merged group call to the core network, so as to trigger the core network to establish a group call downlink channel for each group participating in the merged group call.
Preferably, the dispatcher station may utilize the Invite message to carry the merged group call establishment request, and specifically may send the merged group call establishment request by using the following method:
the dispatching desk sends an Invite message to the core network, wherein the Invite message carries identification information for indicating the request of establishing the merged group call and labels of all groups participating in the merged group call;
and the core network sends a corresponding response message to the dispatching desk according to the Invite message.
In this step, after receiving the merged group call establishment request, the core network, after determining that the merged group call is allowed to be established, establishes a group call downlink channel for each group participating in the merged group call, and simultaneously, triggers a speaking right notification process. The specific processes of establishing the group call downlink channel and sending the speaking right notification are the same as those of the existing system, and are not described herein again.
And 103, judging whether the requested combined group call is successfully established or not by the dispatching desk and/or the core network according to the establishment result of the group call downlink channel and a preset group call success judgment principle, and triggering and releasing corresponding resources if the requested combined group call is failed.
In this step, after the group call downlink channels of all groups are established, it is necessary to determine whether the merged group call is successfully established according to a preset group call success judgment principle, and when it is determined that the establishment fails, it is necessary to trigger the release of the resources occupied by the merged group call in time.
Preferably, the group call success judgment principle may be specifically set as:
if the group calling downlink channels of all groups participating in the merged group calling are failed to be established, the merged group calling is judged to be failed to be established, otherwise, the merged group calling is judged to be successfully established.
In the above principle, it is determined that the merged group call is failed to establish when all group call downlink tunnels of all groups participating in the merged group call are failed to establish, that is, as long as there is a group call downlink tunnel of one group successfully established, the merged group call is considered to be successful, and the merged group call is allowed to normally proceed.
Since the dispatching desk and the core network can both acquire the establishment results of all the group call downlink channels through step 102, both parties can determine whether the establishment of the merged group call is successful, and thus, in practical application, for the release of resources when the establishment of the merged group call fails, the resources can be triggered by the dispatching desk, the core network, or both parties can independently determine and release the resources at the local side, specifically, the following three methods can be adopted:
the method comprises the following steps:
when the dispatching station judges that the establishment of the merged group call fails, the dispatching station sends a BYE message for requesting to release the merged group call to the core network, and releases corresponding resources occupied by the merged group call at the local side; and the core network sends a corresponding response message to the dispatching desk according to the BYE message and triggers and releases a corresponding group call downlink channel.
The second method comprises the following steps:
when the core network judges that the establishment of the merged group call fails, triggering and releasing a corresponding group call downlink channel, and sending a BYE message for notifying the establishment of the merged group call to the dispatching desk;
and the dispatching station sends a corresponding response message to the core network according to the BYE message, and releases corresponding resources occupied by the merged group call at the local side.
The third method comprises the following steps:
when the dispatching desk judges that the establishment of the merged group call fails, the dispatching desk triggers and releases corresponding resources occupied by the merged group call at the local side;
and when judging that the establishment of the merged group call fails, the core network triggers and releases all group call downlink channels of the merged group call.
It can be seen from the above embodiments that the present invention does not need to establish a new group for the merged group call, so that the establishment of the merged group call can be simply and quickly implemented, the success probability of the merged group call is improved, and the maintenance complexity of the group information is reduced. In addition, because the group calling downlink channel is established based on the original group, the terminal displays the original group number called by the actual dispatching desk in the calling process instead of a new strange group number, and the calling experience of the terminal is favorably increased.
After the merged group call is established by adopting the invention, the merged group call carries out normal group call service like a common group call, for example, when the speaking right changes, a speaking right notice is sent in the range of the merged group call.
Fig. 2 is a schematic structural diagram of a group call merging setup system corresponding to the above method, as shown in fig. 2, the system includes:
and the dispatching station DC is used for sending a merged group call establishment request to the core network T-CN, wherein the establishment request carries the labels of all groups participating in the merged group call currently.
The core network is used for judging whether the establishment request is allowed or not and informing the dispatching desk of the judgment result; when the establishment request is allowed, the core network establishes a group calling downlink channel for each group participating in the merged group calling, informs the dispatching desk whether the group calling downlink channel is successfully established, and triggers a process of sending a speaking right notice to the group; and judging whether the requested merged group call is successfully established or not according to the establishment result of the group call downlink channel and a preset group call success judgment principle, and triggering and releasing corresponding resources if the requested merged group call is failed.
Preferably, the dispatcher station is configured to send an Invite message to the core network, where the Invite message carries identification information for indicating that a merged group call is requested to be established and labels of all groups participating in the merged group call;
and the core network is used for sending a corresponding response message to the dispatching desk according to the Invite message.
Preferably, the group call success judgment principle includes: if the group calling downlink channels of all groups participating in the merged group calling are failed to be established, the merged group calling is judged to be failed to be established, otherwise, the merged group calling is judged to be successfully established.
Preferably, the core network is configured to trigger release of a corresponding group call downlink channel when it is determined that the establishment of the merged group call fails, and send a BYE message for notifying that the establishment of the merged group call fails to the scheduling station;
and the dispatching station is used for sending a corresponding response message to the core network according to the BYE message and releasing corresponding resources occupied by the merged group call at the side.
Preferably, the scheduling station is configured to trigger release of corresponding resources occupied by the merged group call at the local side when it is determined that the establishment of the merged group call fails; and the core network is used for triggering and releasing all group call downlink channels of the merged group call when judging that the establishment of the merged group call fails.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
