Before describing the solution in the embodiment of the present application, the following describes a group call right processing procedure of the PDT narrowband digital trunking communication system in the prior art and technical problems to be solved in the embodiment of the present application.
In the prior art, the control method corresponding to the group call right control process of the PDT narrowband digital trunking communication system is executed by taking the right judgment of the master control party as the reference, and specifically comprises the following steps: waiting for master authorization, local authorization/pre-authorization mode.
The general method for waiting for the authorization mode of the master comprises the following steps:
step 1, after receiving the speaking right rejection message (606 message), the current PDT system receives the local speaking right application (set as user 2), and the local speaking right judgment process is not performed:
step 2, the current PDT system sends a speaking right application of the user 2 to the PDT system corresponding to the speaking right control party, and waits for a reply;
and 3, after receiving a speaking right refusing (606) or speaking right authorizing (200) message corresponding to the response of the speaking right application of the user 2, the current PDT system replies to the speaking right application in the PDT system.
The optimizable method for waiting for the authorization mode of the master comprises the following steps:
step 1, after receiving the speaking right rejection message (606 message), the current PDT system records the current speaking right priority as the speaking right priority (denoted as k 3) of the rejected user (set as user 3).
Step 2, the current PDT system receives a local (set as user 2) speaking right application (the corresponding speaking right priority is k 2), and performs speaking right priority pre-judging processing:
Step 3, if step 2 is to send a speaking right request, wait for a response, and reply to the corresponding speaking right application in the PDT system after receiving a speaking right rejection (606) or speaking right authorization (200) message, specifically,
The general method corresponding to the local authorization/pre-authorization mode comprises the following steps:
step 1, after receiving 606 the message, the current PDT system updates the current (set as user 1) speaking right priority (null or unknown);
step 2, the current PDT system receives the local (set as user 2) speaking right application, and the local speaking right judging process fails (cannot be compared):
step 3, the current PDT system sends (user 2) a speaking right application (speaking right priority is k 3) to the PDT system corresponding to the speaking right controller, and waits for a reply;
Step 4, after receiving 606/200 message, the current PDT system replies to the speaking right application in the PDT system, specifically:
step 41, if 200 messages are received, updating the current speaking right priority to k2;
step 42, if a message is received 606, updating the current session priority (null or unknown).
The optimizable method of the local authorization/pre-authorization mode comprises the following steps:
step 1, after receiving 606 the message, the current PDT system records the current speaking right priority as the speaking right priority (k 3) of the refused user (set as user 3);
step 2, the current PDT system receives a local (set as user 2) speaking right application (speaking right priority is k 2), and performs speaking right priority pre-judging processing:
Step 3, if step 2 is to send a speaking right request, wait for a response, and reply to a corresponding speaking right application in the PDT system after receiving a speaking right rejection (606) or speaking right authorization (200) message, specifically:
In summary, whether the host-waiting authorization mode or the local authorization/pre-authorization mode, the following problems exist in the speaking right maintaining stage after receiving 606 the message because the receiving 606 message cannot accurately identify the speaking right priority (k 1) of the current speaking party (user 1), which is also the problem to be solved by the embodiments of the present application: the local has the user to apply speaking right, the speaking right priority of the user cannot be accurately compared, and the immediate right judgment/pre-judgment processing cannot be performed; and sending unnecessary speaking right application (UPDATE) information to the master, so that the master needs to perform more speaking right judgment and processing, and the efficiency of the PDT system interconnection for group call processing is reduced.
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Fig. 1 is a flow chart of a speaking right control method provided in an embodiment of the present application. As shown in fig. 1, an embodiment of the present application provides a session control method applied to a police digital trunked PDT system, the method includes the following steps:
step S101, after a plurality of interconnected PDT systems establish group call, receiving the speaking right rejection information sent by the master PDT system in the plurality of interconnected PDT systems, wherein the speaking right rejection information carries a first speaking right priority corresponding to a first mobile station with current speaking right.
In this embodiment, the corresponding interaction party at least includes a master PDT system and PDT systems corresponding to two requesters, where one PDT system corresponding to two requesters is an execution body for executing the session control method in the embodiment of the application, specifically, one PDT system that receives the session reject information, and the other PDT system receives the session grant information; in this embodiment, a plurality of interconnected PDT systems are set as a PDT system MSC1, a PDT system MSC2, and a PDT system MSC3, where MSC3 is a master PDT system, and MSC1 and MSC2 are requesters.
In this embodiment, when the MS1 mobile station (corresponding to the first mobile station) of the MSC1 and the MS4 mobile station of the MSC2 apply for the speaking right at the same time, the speaking right priority of the MS1 is k1, the speaking right priority of the MS4 is k4, the MSC3 first receives the speaking right application of the MS1 and grants the speaking right, at this time, the MS1 is the mobile station currently speaking, the speaking right response information sent by the MSC3 to the MSC1 is the speaking right grant response information (200 information), the speaking right response information sent by the MSC3 to the MSC2 is the speaking right rejection information (606 information), and the speaking right rejection information carries the user ID of the MS1 and the corresponding speaking right priority (corresponding to the first speaking right priority, denoted as k 1), meanwhile, because the speaking right response information sent by the MSC3 to the MSC1 is the speaking right grant response information (200 information), the mobile station currently speaking can be known to the MS1 and knows that the speaking right corresponding to the MS1 is the speaking right priority corresponding to the MSC1, and therefore the speaking right response information sent by the MSC3 to the MSC2 has the first speaking right priority corresponding to the first mobile station.
The speaking right priority in the embodiment of the application may be an algorithm calculated value, a configuration value, a user priority, and the like.
Step S102, receiving a speaking right application initiated by a second mobile station in the PDT system, determining a second speaking right priority corresponding to the second mobile station, and determining a speaking right preemption result in the PDT system according to the first speaking right priority and the second speaking right priority.
In this embodiment, the PDT system that determines the result of the session preemption is the PDT system where the second mobile station is located.
In this embodiment, after the MSC3 sends the session reject information to the MSC2, the MSC2 grants the session of the first mobile station in the system, and updates the first session priority corresponding to the first mobile station to the session priority corresponding to the system, that is, the MSC2 updates the session priority of the current speaker to k=k1, after that, the MSC2 receives the session application of the mobile station MS2 (corresponding to the second mobile station) in the own system, and the session priority corresponding to the MS2 is set to k2, the MSC2 performs the process of the session application initiated by the MS2 in the system, that is, performs the session preemption judgment based on the session priority k2 (corresponding to the second session priority) corresponding to the MS2 and the first session priority k1, and when k2 is less than or equal to k1, the MSC2 refuses the session application of the MS2 in the system, and does not perform the session application of the MS2 to the master PDT system, and when k2 is greater than k1, the session application is initiated by the MSC2, and the result of the session application is sent by the MSC2 in the master PDT system, that the session application is initiated by the MSC2, and the session application is initiated by the second mobile station.
Step S103, determining whether to send the speaking right application of the second mobile station to the main control PDT system according to the speaking right preemption result, and generating a speaking right initiating result between the corresponding interconnected PDT systems.
In this embodiment, when the result of the speaking right preemption is that the MSC2 refuses the speaking right application of the MS2 in the PDT system, the MSC2 does not need to send the speaking right application of the MS2 to the MSC3, that is, does not need to further judge the speaking right between the interconnected PDT systems through the MSC 3; when the speaking right preemption result is that the MS2 preempts the speaking right of the MS1 in the MSC2, the MSC2 needs to send the speaking right application of the MS2 to the MSC3, that is, needs to further judge the speaking right between the interconnected PDT systems through the MSC 3; in this embodiment, it is determined by each participating PDT system (e.g., MSC2, MSC 1) whether the session request of the user in the system needs to be sent to the master PDT system, that is, the corresponding PDT system performs the session preemption result determination in its own system, and then, the corresponding participating PDT system correspondingly sends the session preemption result corresponding to the system to the master PDT system, and the master PDT system performs the right determination on the received session request, so as to reduce the session interaction between the interconnected PDT systems as a whole, and the master PDT system also avoids unnecessary session right determination processing, and improves the group call efficiency of the interconnected PDT systems and user experience.
In this embodiment, when the MSC3 is required to further determine the session right of the MS2, the session right application of the MS2 needs to be sent to the MSC3 according to the MSC2, and after the MSC3 receives the session right application of the MS2, the second session right priority corresponding to the MS2 is compared with the first session right priority corresponding to the MS1, where the second session right priority is greater than the first session right priority, that is, k2 > k1, the MS2 preemptively occupies the session right of the MS1 in the MSC3, and the MSC3 sends a session right change notification to the MSC 1.
After the group call is established in the plurality of interconnected PDT systems, the step S101 to step S103 are adopted to receive the speaking right rejection information sent by the master PDT system in the plurality of interconnected PDT systems, where the speaking right rejection information carries a first speaking right priority corresponding to a first mobile station with current speaking right; receiving a speaking right application initiated by a second mobile station in the PDT system, determining a second speaking right priority corresponding to the second mobile station, and determining a speaking right preemption result in the PDT system according to the first speaking right priority and the second speaking right priority; according to the speaking right preemption result, determining whether to send the speaking right application of the second mobile station to the main control PDT system, and generating a speaking right initiating result between the corresponding interconnected PDT systems, solving the problems that in the speaking right maintaining process of the prior art, unnecessary speaking right application is sent to the main control party, unnecessary speaking right processing flow is introduced, and group calling efficiency of trunking communication is reduced, realizing accurate judgment of whether the local speaking right application has the speaking right of the user in the conversation, further judging whether the speaking right needs to be sent to the main control PDT system, reducing speaking right interaction between the interconnected PDT systems, avoiding unnecessary speaking right processing flow, and improving user experience and group calling efficiency.

2. The speaking right control method of the embodiment of the application avoids or reduces redundant message interaction, improves the speaking right processing efficiency of the interconnection PDT system, wherein,
avoiding redundant message interactions includes: after receiving the response of refusing the speaking right application, the PDT system has a second mobile station for applying speaking right, and compares the speaking right priority (set as k 2) of the second mobile station with the speaking right priority (set as k 1) of the authorized first mobile station, if k2 is less than or equal to k1, the PDT system directly refuses the second mobile station for applying speaking right;
The improvement of the processing efficiency of the speaking right of the interconnection system comprises the following steps: when the PDT systems participate in a call (such as a group call), each PDT system can accurately judge whether the speaking right application in the PDT system needs to be sent to the main control system, so that speaking right interaction among interconnection systems is reduced as a whole, and the main control PDT system also avoids unnecessary speaking right judgment processing.
3. In the embodiment of the application, after the requester receives the response of the talk right application rejection, the second mobile station applies for the talk right in the PDT system corresponding to the requester, and the PDT system corresponding to the requester immediately issues the talk right grant/rejection, so that the efficiency is almost equal to that of the single system; meanwhile, the speaking right control method in the embodiment of the application has little influence on the idle timing setting of the channel.
