Obviously, the described embodiments These are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative efforts fall within the scope of protection of this disclosure.

Before describing the embodiments of the present disclosure, the related technologies involved in the embodiments of the present disclosure will be described as follows. MCPTT (Mission Critical Push To Talk) is an LTE-based public network cluster solution proposed by 3gpp. The goal is to realize end-to-end PTT (Push To Talk) service and utilize the GCSE ( Group Communication System Enabler (group communication system enablement service) and Prose (Proximity-basedservice, short-distance service) capabilities design the call control process at the application layer to implement cluster functions.

The overall architecture of MCPTT includes the application plane, signaling plane and Evolved Packet System (EPS, Evolved Packet System) bearer plane; among them, the application plane provides all cluster service functions including call control, voice control, etc.; the signaling plane provides application layer signaling Transmission support; the EPS bearer plane is responsible for establishing EPS/MBMS (Multimedia Broadcast Multicast Service) bearers and corresponding data packet transmission according to MCPTT business requirements.

The technical solutions in the embodiments of the present disclosure will be described below with reference to the accompanying drawings in the embodiments of the present disclosure.

FIG. 1 is a schematic flowchart of a group communication method provided by an embodiment of the present disclosure. As shown in Figure 1, the embodiment of the present disclosure provides a group communication method, which is applied in the MCPTT system. The method includes the following steps:

Step S101, in the process of responding to the group reorganization request sent by the target terminal and attaching the plurality of first terminals requested by the target terminal to be reorganized to the corresponding target group, detecting whether there are communication link resources allocated for the first terminal, where , the communication link resource is used for communication between the first terminal and the second terminal in the waiting group in which it is located.

In this disclosure, the execution subject includes but is not limited to the server in the MCPTT system, and executes the call request and group reorganization scheduling, that is, receives the target terminal's request for group reorganization, and then sends the corresponding terminal requesting reorganization based on the group reorganization request. Pulled into the target group, you can also receive requests from the target terminal to call terminals in the target group after the group reorganization is completed and establish corresponding calls, as well as receive non-target terminals (corresponding to terminals to be attached to the target group, also That is, multiple first terminals to be attached to the target group) call requests to terminals in the original waiting group (corresponding to the second terminal) and establish corresponding group communication calls.

In this disclosure, the target terminal is a terminal that applies for authorization from the server and is authorized. The permissions given by the server to the target terminal include at least applying for group reorganization; in the embodiment of the present application, the target terminal applies for group reorganization by applying for more attached terminals. Call groups for richer voice interaction and SMS notifications.

In this disclosure, the so-called target group is a talk group composed of multiple terminals to which the target terminal applies to be attached, and the so-called waiting group is the talk group where the corresponding terminal (first terminal) was before being attached to the target group by the server; in this disclosure , other terminals (non-first terminals) in the waiting group correspond to second terminals, and the number of second terminals in the waiting group is not limited.

In the present disclosure, the first terminal can at least make calls to other terminals in the same group (waiting group) (the corresponding calls include calls that have been established with the corresponding second terminal or calls that are being initiated to the corresponding second terminal) , at the same time, after the target terminal group reorganization is completed, the target terminal can make a call to the first terminal attached to the target group; in the present disclosure, before the group reorganization is completed, the first terminal is attached to the waiting group, and at the same time, A terminal that belongs to the target group to which the target terminal requests group reorganization is to be attached; after the group reorganization is completed, the first terminal is at least attached to the waiting group and the target group.

In the present disclosure, after the target terminal requests group reorganization, the server sends a group reorganization request to the corresponding first terminal according to the received group reorganization request, and sequentially pulls the first terminal into the target group; before completing all the group reorganization requests, the server sends a group reorganization request to the corresponding first terminal. When the first terminal is pulled into the target group, the first terminal to be reorganized (not pulled in) sends a call request to the server, requesting to call the second terminal in the waiting group to which the first terminal originally belongs.

In the present disclosure, when the first terminal does not establish a group communication call with the corresponding second terminal, the server receives the group communication call request initiated by the first terminal to the second terminal that also belongs to the waiting group and performs user authority judgment ( After determining whether the corresponding first terminal can make a group communication call), the first terminal is notified that the call is successfully established, and the corresponding communication link resource (corresponding media plane) is allocated to make the group communication call.

In this disclosure, after receiving the group reorganization request sent by the target terminal, the server will detect whether there is a communication link allocated to the first terminal for the first terminal to communicate with the second terminal in the waiting group in which it is located. Resources, the allocation of communication chain resources can be completed before the server receives the group reorganization request, that is, before the server receives the group reorganization request, the first terminal to be reorganized has already communicated with the second terminal that also belongs to the waiting group. Make a group communication call; it can also be allocated during the process of the target terminal making a group reorganization request, that is, before the server receives the group reorganization request and sends the group reorganization request to the corresponding first terminal, corresponding to the first group reorganization to be In the process of belonging to the target group, the terminal initiates a group call call request to the second terminal that also belongs to the waiting group. During the process of the target terminal making a group reorganization request, that is, the communication link resources allocated by the server before receiving the group reorganization request and issuing the group reorganization request to the corresponding first terminal are randomly allocated by the server and are not temporarily set. .

In the present disclosure, after the server checks that the corresponding communication link resource is allocated to the first terminal, it can send the group reorganization request to the first terminal using the communication link resource, and then execute the group reorganization process.

In this disclosure, the group reorganization request includes target information of the target terminal, target information of the target group, group member information of the target group, and status identification information attached to the target group; specifically, the group reorganization request needs to carry at least the following information: Target The terminal corresponding identification ID, the group identification ID requesting group reorganization (corresponding to the target group identification ID), the group identification ID list of the group members (first terminal) in the reorganization group (corresponding to the target group), and whether each group member has been successfully pulled into the reorganization. Group (corresponding to the target group) information.

Step S102: When there is a communication link resource allocated for the first terminal to communicate with the second terminal, send a group reorganization request to the first terminal through the communication link resource to attach the first terminal to the target group.

In the present disclosure, after the server checks the allocated communication link resources (including those allocated before sending the group reorganization request and those allocated during the group reorganization process), the server issues the group reorganization request to the corresponding first communication link through the communication link resource. terminal, if the first terminal receives the group reorganization request, the server will pull the first terminal into the target group. At this time, the first terminal is at least affiliated with the waiting group and the target group.

In the present disclosure, after the server attaches multiple first terminals to the corresponding target group in sequence, it will record the attachment status information of the corresponding first terminal. For example, the first terminal A is attached to the waiting group 1 and the target group 2.

Through the above-mentioned steps S101 to S102, in the process of responding to the group reorganization request sent by the target terminal and attaching the multiple first terminals requested by the target terminal to the corresponding target group, it is detected whether there is a group allocated to the first terminal. Communication link resources. The communication link resources are used for communication between the first terminal and the second terminal in the waiting group; in the case where there are communication link resources allocated for the first terminal to communicate with the second terminal, through The communication link resource issues a group reorganization request to the first terminal to attach the first terminal to the target group, which solves the problem in related technologies that the group reorganization service affects the group communication initiated by the user, resulting in poor user experience, and achieves Both call services and group reorganization services can be performed normally, which satisfies the private network usage habit of giving priority to call services and has the beneficial effect of improving user experience.

It should be noted that the problem solved by the group communication method of the embodiment of the present disclosure also includes the related technology. During the group reorganization process, the server refuses the first terminal requested for group reorganization to send a request to the second terminal in the waiting group to which it is attached. For a group communication call initiated by the terminal, the corresponding group communication call is not allowed until the group reorganization request is completed, so that the corresponding user needs to wait for a long time and the user experience is poor; at the same time, in related technologies, it is also solved that if requested The first terminal for group reorganization has already made a group communication call with the second terminal in its attached waiting group before the server receives the group reorganization request. Some terminals cannot receive the group reorganization request or are forced to hang up the corresponding group communication call by the server. The problem.

It should be further explained that after the target terminal requests group reorganization, if the server does not receive the call request from the corresponding first terminal, it will sequentially issue group reorganization requests to the corresponding multiple first terminals, and sequentially send the corresponding group reorganization requests to the corresponding first terminals. Pull in the set target group until the reorganization is completed.

In some of these embodiments, the following steps are also performed:

Step 21: When receiving the second call initiated by the target terminal to the first terminal in the target group after completing the group reorganization, obtain the priority information corresponding to the first call and the second call respectively, where the priority information is To characterize the level of the call, the first call is a call between the first terminal and the second terminal in the waiting group.

In the present disclosure, after the group reorganization is successful, the target terminal can make a group communication call to all terminals in the target group. At this time, the target terminal sends a corresponding call request (corresponding to the second call) to the server, and then makes a call to the server through the server. Judgment of the call request (judgment of the corresponding priorities of the first call and the second call), thereby creating the corresponding call. In the present disclosure, the first call includes one of the following: a group communication call established between the first terminal and the corresponding second terminal before the target terminal sends the group reorganization request, a call during the process of the first terminal attaching to the target group , the first terminal initiates a group communication call with the second terminal in the waiting group.

In the present disclosure, the server or the first terminal may perform the acquisition of priority information. In some optional implementations, when the server does not perform priority selection of two or more calls, the first terminal A terminal performs the priority selection of the corresponding call; in the present disclosure, the preferred server performs the priority selection of the call.

In this disclosure, priority information is used to represent the level of the call. The level of the call is also used to indicate the priority of the call. The level of the call is preconfigured by the server according to the network conditions. When a group call with a high priority is received , the server gives priority to establishing calls to the corresponding group.

Step 22: Determine the call selection result based on the priority information, and perform group communication based on the selection result.

In the present disclosure, the call selection result is determined based on the priority level corresponding to the priority information.

Through the above steps 21 to 22, when receiving the second call initiated by the target terminal to the first terminal in the target group after completing the group reorganization, the priority information corresponding to the first call and the second call is obtained respectively, The priority information is used to represent the level of the call. The first call is a call between the first terminal and the second terminal in the waiting group. Based on the priority information, the call selection result is determined, and group communication is performed based on the selection result. After the group reorganization is successful, the calls will be selected based on the call priority of the corresponding affiliated group, so that calls with high priority are established first, which satisfies the private network usage habit of prioritizing call services and further improves user experience.

In one embodiment, step 22 determines the call selection result based on the priority information, and performs group communication based on the selection result, and is implemented through the following steps:

Step 31: Determine the first call priority of the call corresponding to the first call request and the second call priority of the call corresponding to the second call request based on the priority information.

Step 32: Determine the size of the first call priority and the second call priority.

Step 33: When it is determined that the first call priority is greater than the second call priority, determine that the first terminal remains in the first call.

In this disclosure, after it is determined that the first call priority is greater than the second call priority, it indicates that the call priority corresponding to the target group for group reorganization is lower than the call priority corresponding to the waiting group, and the server does not notify the target terminal of the group reorganization. The call information of the target group means that the call to the target terminal fails, and the server maintains the call between the original first terminal and the second terminal in the waiting group, that is, the first terminal maintains the first call.

Step 34: When it is determined that the priority of the first call is lower than the priority of the second call, hang up the first call, that is, hang up the call between the first terminal and the second terminal in the waiting group, and make the second call. .

In the present disclosure, after it is determined that the second call priority is greater than the first call priority, it indicates that the call priority corresponding to the target group for group reorganization is higher than the call priority corresponding to the waiting group, and the server hangs up with the first terminal. The call of the corresponding second terminal is connected to the call of the target group, that is, a group communication call is established between the target terminal and the corresponding first terminal in the target group.

Step 35: When it is determined that the first call priority and the second call priority are the same, group communication is performed based on the first terminal's selection of the first call and the second call.

In the present disclosure, when the first call priority and the second call priority are the same, the second call request is sent to the first terminal, and the first call request and the second call request are processed according to the first terminal. The group communication call is selected and the corresponding group communication is performed. For example: the first terminal selects the first call, then the corresponding group communication is the first call; in this disclosure, if the server determines the priority of the first call and the second call If the priorities are the same, the server will not make a selection. The server will deliver the corresponding call information to the first terminal and prompt the user associated with the first terminal with the current call information, so that the user can choose to connect the corresponding call.

According to the priority information in the above steps 31 to 35, the first call priority of the call corresponding to the first call request and the second call priority of the call corresponding to the second call request are respectively determined; determine the first call priority and the size of the second call priority; when it is determined that the first call priority is greater than the second call priority, determine that the first terminal remains in the first call; when it is determined that the first call priority is less than the second call priority In the case of call priority, hang up the first call and make the second call; when it is determined that the first call priority and the second call priority are the same, the first call and the second call are The selection is performed for group communication to realize the selection of calls with different call priorities, thereby allowing the server to create more important calls, satisfying the private network usage habit of prioritizing call services, and further improving the user experience.

In one embodiment, before obtaining the priority information corresponding to the first call and the second call in step 21, the following steps are also performed: when it is determined not to perform call priority selection, based on the first terminal's The selection of the first call and the second call performs the group communication.

In the present disclosure, when receiving the second call initiated by the target terminal to the first terminal in the target group after completing the group reorganization, if the server determines not to perform call priority selection, the server sends the corresponding call information to the first terminal, and prompts the current call information of the user associated with the first terminal, and the user chooses to connect the corresponding call.

In one embodiment, sending the group reorganization request to the first terminal through the communication link resource in step S102 is implemented through the following steps: using the session initiation protocol SIP or the hypertext transfer protocol HTTP, the group reorganization request is sent through the communication link The resource (corresponding media plane) is sent to the first terminal.

FIG. 2 is another schematic flowchart of a group communication method provided by an embodiment of the present disclosure. As shown in Figure 2, an embodiment of the present disclosure provides a group communication method applied to terminals to be group reorganized. The method includes the following steps:

Step S201: After communicating with a second terminal in the same waiting group through a communication link resource allocated by a preset server, a group reorganization request is received, where the server receives a group reorganization request sent by the target terminal requesting group reorganization. Finally, the group reorganization request is issued through the allocated communication link resources.

In the present disclosure, the execution subject is the terminal requested by the target terminal for group reorganization, which is defined as the first terminal; in the present disclosure, before the first terminal receives the corresponding group reorganization request, the first terminal can be the same as the waiting terminal. The second terminal of the group has a call, or it can have a call with the corresponding second terminal before the target terminal initiates the group reorganization request, and the first terminal uses the server (server of the MCPTT system) to communicate with the second terminal. The communication link resource (corresponding to the media plane) is completed, and after the corresponding call is established, it indicates that the corresponding communication link resource must exist. At the same time, to establish the corresponding call, it must be in the allocated communication link carried out on road resources.

In the present disclosure, after the execution subject and the second terminal have a corresponding call (indicating that communication link resources already exist), the server can send a group reorganization request through the communication link resource. The execution subject (first The terminal) receives the corresponding group reorganization request through the communication link resource.

Step S202: Respond to the group reorganization request through communication link resources to be attached to the target group requested by the target terminal for group reorganization.

In the present disclosure, after the first terminal receives the corresponding group reorganization request, it will respond to the group reorganization request, and the corresponding target group will be attached to the group reorganization requested by the target terminal.

Through the above-mentioned steps S201 to step S202, the group reorganization request is received after the server communicates with the second terminal in the same waiting group through the communication link resource allocated by the preset server, wherein the server receives the request for group reorganization. After the group reorganization request is sent by the target terminal, the group reorganization request is issued through the allocated communication link resources; the group reorganization request is responded to through the communication link resources to be attached to the target group requested by the target terminal for group reorganization, thereby realizing the terminal's group communication Calls are not affected by group reorganization services, and can ensure that both call services and group reorganization services are carried out normally. This prevents terminals from being unable to make corresponding group communication calls or being forcibly hung up on group communication calls during the requested group reorganization process, thus improving user experience.

In one embodiment, the following steps are also performed:

Step 41: After the server determines that the priority of the call initiated by the target terminal is greater than the priority of the call established with the second terminal in the same waiting group, a group communication call is established with the target terminal.

In the present disclosure, after the first terminal is attached to the corresponding target group, the first terminal can establish a call with the second terminal in the original waiting group through the server, and can also establish a call with other first terminals in the target group. The call; the choice of whether to call the second terminal or another first terminal is determined by the priority of the call initiated by the server, and the server will select the call with a higher priority.

Step 42: When the server determines that the priority of the call initiated by the target terminal is lower than the priority of the call established with the second terminal in the same waiting group, maintain the call with the corresponding second terminal in the same waiting group.

In the present disclosure, the terminal is implemented to select a call with a high priority based on the server, so that the terminal can talk to the corresponding terminal, thereby improving the user's favorability.

Figure 3 is a flow chart of a group communication method according to a preferred embodiment of the present disclosure. Referring to Figure 3, the method includes the following steps:

Step 1: Target terminal B initiates a group reorganization request for target group 2, and the first terminal to be reorganized includes terminal A.

Step 2: Group reorganization response. After the server receives the group reorganization request, it will sequentially send the group reorganization request to the first terminal to be reorganized, and pull the first terminal into target group 2.

Step 3: Terminal A initiates a call request for waiting group 1.

Step 4: The call is successfully established. After receiving the call request from terminal A, the server selects the user rights associated with terminal A and notifies the user that the call is successfully established. Terminal A and the second terminal in waiting group 1 enter the allocated media. Make a call on the interface (corresponding to the communication link resource).

Step 5: When the server detects that terminal A has already made a call on the media plane, it needs to issue a group reorganization request on the corresponding media plane. The group reorganization request needs to carry at least the ID of the requested target terminal and the number of the assigned target group. ID, a list of group IDs of multiple first terminals, and whether each first terminal is successfully added to the target group.

Step 6: After receiving the group reorganization request, terminal A attaches to the target group 2. Terminal A has attached to at least two groups: waiting group 1 and target group 2.

In the present disclosure, if the server carries response information required, terminal A sends a group reorganization response to the server, and then the server records the attachment status of multiple first terminals of target group 2.

Figure 4 is a flow chart of different call priority selection according to a preferred embodiment of the present disclosure. Referring to Figure 4, the selection process includes the following steps:

Step 1: After terminal A initiates a call to wait for group A and successfully establishes it, it receives a group reorganization request and attaches itself to target group D.

Step 2: When all group reorganization of target group D is completed, target terminal B can initiate a call to target group D.

Step 3: Call for selection.

In this disclosure, if the server does not perform call priority selection, terminal A performs call selection; terminal A determines the call priority of the call. If the call priority of target group D is low, that is, the call of target group D If the priority is lower than the call priority of waiting group A, the server is notified that the call access of target group D fails. If the call priority of target group D is higher, that is, the call priority of target group D is greater than the call priority of waiting group A. , then after hanging up the call of waiting group A, a call of target group D is established.

Figure 5 is a flow chart of the same call priority selection according to a preferred embodiment of the present disclosure. Referring to Figure 5, the selection process includes the following steps:

Step 3: Call for selection.

In this disclosure, if the server finds that the call priority of target group D is the same as the call priority of waiting group A, the server does not make a selection. The server delivers the call information corresponding to the call to terminal A, and prompts terminal A to associate it with The user's current call information, and the corresponding user chooses to connect the corresponding call, for example: choose to hang up the call of waiting group A and establish a call of target group D.

The present disclosure also provides a group communication device, which is used to implement the above embodiments and preferred implementations. What has been described will not be described again. The terms "module", "unit", "subunit", etc. used below may be a combination of software and/or hardware that implements predetermined functions.
