The broadband trunking communication system is developed for meeting the demand of industry user command and scheduling, 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 group call service is the most basic service provided by the broadband trunking communication system. For each group calling service, the cluster core network sets time parameters such as speaking right duration, speaking right idle duration, total calling duration and the like. When the cluster core network grants the speaking right to the terminal, the speaking right time length timer is started. When the terminal releases the speaking right, the cluster core network stops the timer, otherwise, after the timer is overtime, the network side forcibly releases the speaking right of the terminal; for normal mobile terminals, the user can be prompted by the alternative NAS message, the SPEAKING right, to time out.
In the current speaking right distribution process, there is no speaking right time notification mechanism used between the dispatching desk and the cluster core network, and the cluster core network cannot notify the dispatching desk that the speaking right is about to overtime, which also results in that a dispatcher cannot execute speaking right duration: if the time that the dispatching desk occupies the speaking right exceeds the speaking right duration, that is, in the speaking right distribution process, the speaking right can only be obtained by re-initiating the speaking right application process after the speaking right is forcibly released, the speaking right duration cannot be triggered in the time-efficient process of the speaking right, and the effectiveness and the real-time performance of dispatching command can be seriously influenced for industrial users with high dispatching real-time requirements for public security, fire protection and the like.

In order to explain the scheme further, the invention also provides an application example of the distribution method of the speaking right in the group call service. Referring to fig. 9, the allocation method specifically includes the following steps:
(1) in the group calling conversation process, if a dispatcher wants to apply for the speaking right, the DC sends an SIP (reINVITE) message to a cluster core network to request the group calling speaking right;
(2) the cluster core network grants the speaking right to the DC which applies for the speaking right at present, and then sends SIP (200(OK)) information to the DC to complete the speaking right application process;
(3) after receiving the speaking right authorization, the dispatching station sends SIP (ACK) information to the cluster core network to confirm that the speaking right application process is completed;
(4) after receiving an SIP (ACK) message sent by a dispatching desk, the cluster core network internally starts a speaking authority timer according to configuration information;
(5) the cluster core network informs other group members in the group of the speaking right occupation information through a cluster downlink transmission message;
(6) after the timer started in the step (4) is overtime, the cluster core network sends a SIP (message) message to the dispatching desk to inform the dispatching desk that the speaking right authorization is about to overtime;
(7) the dispatching desk replies SIP (200(OK)) message to the cluster core network;
(8) after receiving the sip (message) message of step 6, the dispatcher station may perform friendliness prompt on the interface of the dispatcher station, for example: the talk burst also has a 10 second timeout, providing the user with two operational options, "determine" and "talk burst duration". If the user feels that 10 seconds are enough, clicking to determine; if the user feels that the speaking right needs to be occupied for a period of time, the dispatching desk sends an SIP (reINVITE) message to the cluster core network, triggers the speaking right duration and indicates the expected duration;
(9) the cluster core network decides the speaking right attribution according to the speaking right decision policy and sends a SIP (200(OK)) message to the DC if the speaking right is granted to the dispatch station. Starting an speaking right time timer according to the speaking right occupation time expected by the dispatcher;
(10) after receiving the speaking right authorization, the dispatching desk sends SIP (ACK) information to the cluster core network to confirm that the speaking right renewal process is completed.
The speech right time notification mechanism in the above description: when the cluster core network grants the speaking right to the dispatching desk, a speaking right time limit timer is started, and the time length of the timer can be flexibly configured (for example, the speaking right time length is reduced by 5 seconds). When the timer is overtime, the cluster core network sends SIP (message) message to the dispatching desk to indicate that the speaking right of the dispatching desk is about to overtime; the speaking right renewal method comprises the following steps: when receiving the speaking right time information, the dispatching desk triggers the speaking duration and sends SIP (REINVITE) information to the cluster core network, and the cluster core network carries out the speaking right duration processing according to the decision strategy; two additional SIP messages: two messages, namely SIP (message) and SIP (REINVITE), are added in the patent.
From the above description, the application example of the present invention provides a novel speaking right time reminding mechanism for reminding a dispatcher of that a group calling speaking right is about to overtime; meanwhile, a novel speaking right duration method is provided, after the reminding message is sent to the dispatching desk during speaking right, the dispatcher triggers the speaking right duration according to the use requirement, and the duration time can be flexibly set by the dispatcher.
An embodiment ninth of the present invention provides a specific implementation manner of a cluster core network, which can implement steps 100 to 500 in the foregoing method. Referring to fig. 10, the cluster core network specifically includes the following contents:
the time-limited timer starting unit 10 is configured to start, in a broadband trunking communication system, a time-limited timer corresponding to a speaking right of a scheduling station according to the speaking right authorization confirmation information sent by the scheduling station, and send occupation information of the speaking right to other user terminals in a group in which the scheduling station is located, where a timing duration of the time-limited timer is less than a predetermined duration of the corresponding speaking right.
And the speaking right reminding unit 20 is configured to send speaking right reminding information to the dispatching desk after the time-limited timer finishes timing, so that the dispatching desk obtains the remaining occupied time of the speaking right according to the speaking right reminding information, where the speaking right reminding information includes the remaining occupied time of the speaking right corresponding to the dispatching desk.
As can be seen from the above description, the specific embodiment of the present invention can prompt the dispatching desk timely and accurately when the speaking right is about to overtime, so that the dispatching desk can know the remaining occupied time of the speaking right according to the speaking right prompting information, and the stability and reliability of the dispatching desk communication are ensured.
