Description

A method for dynamically changing cluster terminals in group calls

technical field

The invention relates to the field of cluster communication, in particular to a method for dynamically changing a cluster terminal in a group call.

Background technique

With the wide application of trunking communication systems in various industries, users have put forward higher and higher requirements for trunking communication. For example, it is sometimes necessary to dynamically increase members during group calls, which is helpful for improving the user experience and flexibility of trunking communication systems. Is of great significance.

A group call is a half-duplex call between one calling party and multiple called parties. Group calls can be initiated by authorized users. Users with group call initiation rights dial the called group number and press and hold the PTT key to initiate a group call. A terminal user may belong to multiple groups, and the number of users in a group will continue to increase. The customization of user rights can be specific to different levels such as system, group, group and user. For a user terminal, in most cases it has the right to selectively join a call, and in certain cases also has the right to withdraw from any group call.

Referring to FIG. 1, FIG. 1 is a schematic diagram of inviting users outside the group to join a group call. Assume that users A, B, and C belong to group 1, and users A, D, E, and F belong to group 2. If user A initiates a call to group 1, the user in group 1 needs to discuss some issues with user D during the call. Communication confirmation, and after the communication is completed, user D can exit the group call in time. In the current trunking communication system, if users outside the group join the ongoing group call, the current group call needs to be released first, and a temporary group is established through dynamic reorganization on the network side. , and notify all relevant users of the temporary group information, and then initiate a group call to the temporary group, which affects user experience, increases signaling burden, and cannot solve the above problems flexibly.

In the existing implementation schemes, several solutions are proposed, but none of them can solve the function of dynamically inviting a cluster terminal to join during the group call process. Several specific solutions proposed are as follows:

1. The application number is 200810216180.1, and the patent name is "a method and system for initiating a group call by a user outside the group", which proposes a method for initiating a group call by a user outside the group. The group call authority allows authorized users to temporarily initiate calls to groups they do not belong to. So as to meet the scheduling needs of some special groups of people. The disadvantage of this method is that users outside the group cannot be dynamically added during the group call.

2. The application number is 200710000624, and the patent name is "method and device for user access to group call in trunking system", which makes the group ID on the network side consistent with the user's group ID through a predetermined method, and then the base station uses the group ID to construct a corresponding A paging message is sent to the user. The disadvantage of this method is that there is no function of dynamically inviting a cluster terminal to join in the group call process.

3. The application number is 200610098728, and the patent name is "a method and system for business users to join a group call". In the cell of the group call channel, it is impossible to join the group call. How to make users outside the group join the group call is not solved.

Contents of the invention

The main purpose of the present invention is to provide a method for dynamically changing the trunking terminal in a group call, which improves the user experience and flexibility of the trunking communication system.

A method for dynamically changing a cluster terminal in a group call, in which authority configuration is performed on the network side in advance, indicating that the user terminal has different permissions to send requests for dynamically changing the cluster terminal in the group call to the network side, and the method includes the following steps:

A. The user terminal in the group call sends a request to the network side to dynamically change the cluster terminal in the group call, and the request includes sending the information of the requesting user terminal and the requested user terminal;

B. After the network side receives the request for dynamically changing the cluster terminal in the group call, check whether the requesting user terminal has the authority to initiate a request for dynamically changing the cluster terminal in the group call according to the permission configuration, and if so, send the request to the requested user The terminal sends the request for dynamically changing the trunking terminal in the group call, and goes to step C, otherwise, executes step D;

C. After receiving the request for dynamically changing the cluster terminal in the group call, the requested user terminal sends a request response to the network side, and executes step D;

D. The network side sends a request response to the requesting user terminal, and dynamically changes the cluster terminal in the group call.

Wherein, after the network side in the step B receives the request for dynamically changing the cluster terminal in the group call, it further includes establishing an invitation list;

After the network side dynamically changes the trunking terminal in the group call in the step D, the network side further includes updating the invitation list.

The information of the sending requesting user terminal is identification information of the sending requesting user terminal.

The request for dynamically changing the cluster terminal in the group call is a request for inviting user terminals outside the group to join the ongoing group call;

The information of the requested user terminal is information that the requested user terminal can join the group call currently in progress;

In the step C, after the requested user terminal receives the request for dynamically changing the cluster terminal in the group call, if it accepts the request, it sends an acceptance request response to the network side; if it rejects the request, it sends a rejection response to the network side request response;

In the step D, when the requesting user terminal has the authority to initiate a request, and the requested user terminal accepts the request of the requesting user terminal, the network side sends an acceptance request response to the requesting user terminal, and the requested The user terminal joins the ongoing group call; when the requesting user terminal has no authority to initiate a request, or the requested user terminal rejects the request of the requesting user terminal, the network side sends a rejection request response to the requesting user terminal, so The requested user terminal has not joined the ongoing group call.

In the step A, the user terminal that is conducting a group call is a user terminal outside the group that is being invited into the group call;

The request for dynamically changing the trunking terminal in the group call is a request for exiting the currently ongoing group call;

In the step B, after the network side receives the request to exit the currently ongoing group call, it directly executes step D;

In the step D, when the requesting user terminal has the authority to initiate a request, the network side sends an acceptance request response to the requesting user terminal, and the requesting user terminal exits the currently ongoing group call; when the requesting user terminal does not The authority initiates a request, and the network side sends a rejection request response to the requesting user terminal, and the requesting user terminal fails to exit the currently ongoing group call.

The request for dynamically changing the trunking terminal in the group call is a request for an out-of-group user terminal invited into the current group call to exit the current group call;

In the step C, after the requested user terminal receives the request from the user terminal outside the group invited to the current group call to exit the current group call, if the request is accepted, an acceptance request response is sent to the network side; The above request is sent to the network side to reject the request;

In the step D, when the requesting user terminal has the authority to initiate a request, and the requested user terminal accepts the request of the requesting user terminal, the network side sends an acceptance request response to the requesting user terminal, and the requesting user terminal The terminal exits the currently ongoing group call; when the requesting user terminal has no authority to initiate a request, or the requested user terminal rejects the request of the requesting user terminal, the network side sends a rejection request response to the requesting user terminal, so The requesting user terminal fails to exit the currently ongoing group call.

The request for dynamically changing the trunking terminal in the group call is a request for releasing the currently ongoing group call;

In the step C, after receiving the request for releasing the currently ongoing group call, the requested user terminal further includes accepting the request unconditionally;

In the step D, when the requesting user terminal has the authority to initiate a request, the network side sends an acceptance request response to the requesting user terminal to release the ongoing group call; when the requesting user terminal does not have the authority to initiate the request, the network side Sending a reject request response to the requesting user terminal to maintain the ongoing group call.

It can be seen from the above scheme that by adding an invitation mechanism control strategy on the network side to maintain the invitation list; adding a little signaling interaction between the terminal and the network side to dynamically invite one or several members to join the current group call, and to dynamically update group call members. purpose, and enable the group call user terminal to exit the group call flexibly. The experience of the user terminal is improved, the signaling burden of the network is reduced, and the method for dynamically changing the trunking terminal in a group call is flexibly realized.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

The present invention adds an invitation mechanism control strategy on the network side, maintains the invitation list, and adds a little signaling interaction between the terminal and the network side, so as to dynamically invite one or several members to join the current group call, and achieve the purpose of dynamically updating group call members. And the group call user terminal can be flexibly withdrawn from the group call.

Referring to Fig. 2, Fig. 2 is a flow chart of inviting a user terminal outside the group to join a group call in the present invention. The network side needs to configure different permissions in advance according to different user terminals to indicate whether it has the right to invite a certain user terminal to an ongoing call. Group call, the specific steps to invite user terminals outside the group to join the group call are as follows:

Step 201, a group call is in progress.

Assume that the group that is making a group call is group 1.

Step 202, user terminal A in the group sends a group call invitation request for user terminal D and user terminal E outside the group to the network side.

The user terminal A that is in the group call sends a group call invitation request to the network side for the user terminal D and the user terminal E outside the group, and the invitation request carries the identification and speech authority of the invited user terminal.

Step 203: After receiving the group call invitation request from user terminal A, the network side performs authority judgment to check whether user terminal A has the authority to invite user terminal D and user terminal E to the ongoing group call, and if so, proceed to step 203. 204, 205, otherwise, go to step 210.

The network side checks the authority of user terminal A. If it passes, it means that user terminal A has the authority to invite user terminal D and user terminal E. At the same time, an invitation list is established. There are user terminal D and user terminal E in the invitation list, otherwise user terminal A is rejected Invitations sent.

In steps 204 and 205, the network side sends the invitation request of user terminal A to the invited user terminal D and user terminal E.

In this embodiment, the network side initiates an invitation request to user terminal D, and carries the identification of user terminal A and the information required for user terminal D to join the group call, that is, user terminal D can establish a group call channel and receive the invitation request from other user terminals. call information;

The network side initiates an invitation request to user terminal E, carrying the ID of user terminal A and the information required for user terminal E to join the group call, that is, user terminal E can establish a group call channel and receive call information from other user terminals.

In steps 206 and 207, user terminal D and user terminal E return invitation responses to the network side respectively.

After user terminals D and E receive the invitation request, they can decide whether to join the group call. As in this embodiment, user terminal D accepts the invitation and returns a response message accepting the invitation to the network side; user terminal E rejects the invitation and returns a response message to the network side. Response message for declining invitation

Step 208, user terminal D joins the ongoing group call.

When user terminal D joins the group call and applies for the right to speak, the network side handles it according to the corresponding right to speak control policy, and user terminal D can broadcast the speaking right notification message to user terminals in the group.

Step 209, the network side updates the invitation list of the ongoing group call.

When user terminal D accepts the invitation and user terminal E rejects the invitation, the network side updates the invitation list, and only user terminal D is in the list.

Step 210, the network side sends the invitation responses of user terminal D and user terminal E to user terminal A.

User terminal D sends to user terminal A an acceptance response request, and user terminal D joins the currently ongoing group call; user terminal E sends a rejection response request to user terminal A, and user terminal E does not join the currently ongoing group call.

The speaking right of the user terminal invited by the group call is only valid in the current group call session. After the group call is released, the invitation list is updated and the invited user terminal is deleted. When the group call is initiated next time, the speaking right of the previously invited user terminal will not be valid. Effective again.

Referring to Fig. 3, Fig. 3 is a flow chart of an invited user terminal voluntarily withdrawing from a group call in the present invention. The network side needs to pre-configure the rights of different user terminals to indicate whether it has the right to request to voluntarily withdraw from a certain ongoing group call. The specific steps to invite the user terminal to actively exit the group call are as follows:

In step 301, user terminal D is making a group call as the invited user terminal.

Step 302, the user terminal D sends a group call exit request to the network side.

Step 303, the network side judges whether the user terminal D has the authority to issue a request to exit the current group call, if yes, send a group call exit acceptance response, and update the invitation list, otherwise send a group call exit rejection response.

Step 304, the network side sends a group call exit response to user terminal D.

If user terminal D has the authority to issue a request to exit the current group call, the network side will send a group call exit acceptance response to user terminal D, and user terminal D will exit the current group call, otherwise send a group call exit rejection response to user terminal D , user terminal D does not exit the currently ongoing group call.

Referring to Fig. 4, Fig. 4 is a flow chart of the present invention for an invited user terminal to withdraw from a group call passively. The network side needs to pre-configure the authority of different user terminals to indicate whether it has the authority to require an invited user terminal to withdraw from its ongoing group call. Call, the specific steps for the invited user terminal to passively withdraw from the group call are as follows:

Step 401, user terminal A is making a group call.

In step 402, user terminal A sends a request for user terminal D to exit the current group call to the network side.

Step 403 , the network side judges whether the user terminal A has the right to send the request, if yes, execute step 404 , otherwise execute step 407 .

Step 404, the network side sends a group call exit request to the user terminal D.

The network side determines that user terminal A has the right to request user terminal D to exit the group call, and the network side sends a group call exit request to user terminal D.

Step 405, the user terminal D sends a group call exit response to the network side.

If the user terminal D accepts the request, it sends a group call acceptance exit response to the network side, otherwise it sends a group call rejection exit response to the network side.

Step 406, the network side updates the invitation list of the ongoing group call.

The network side deletes user terminal D from the list.

Step 407, the network side sends a group call exit response to user terminal A.

When the network side judges that user terminal A does not have permission to send user terminal D's request to exit the current group call or user terminal D refuses to exit the current group call exit request, the network side sends a group call exit rejection response to user terminal A, and user terminal D Did not exit the current group call; when the network side judges that user terminal A has the right to send user terminal D’s request to exit the current group call, and user terminal D accepts the current group call exit request, the network side sends user terminal A A group call exit acceptance response is sent, and user terminal D exits the currently ongoing group call.

Referring to Fig. 5, Fig. 5 is a flow chart of group call release in the present invention, the network side needs to pre-configure the authority of different user terminals to indicate whether it has the authority to initiate a group call release request for the ongoing group call, the specific details of group call release The steps are:

Step 501, user terminal A is making a group call.

Step 502, user terminal A sends a group call release request to the network side.

Step 503, the network side performs authority judgment to determine whether user terminal A has the authority to issue the group call release request, and if so, the network side invites user terminal B in the group, user terminal C in the group, and user terminals outside the group to the user terminal in the group D sends a group call release request, otherwise step 507 is executed.

In steps 504, 505, and 506, the network side sends the group call release command to user terminal B, user terminal C, and user terminal D respectively.

User terminal B, user terminal C and user terminal D accept the request of user terminal A unconditionally.

Step 507, the network side sends the group call release response command to user terminal A.

If user terminal A has the authority to issue the group call release request, the network side sends a group call release acceptance response command to user terminal A, and the group call is released, otherwise, sends a group call release rejection response command to maintain the current group call.

It can be seen from the above that when inviting user terminals outside the group to join, there is no need to release the group call, which improves the flexibility of user terminal experience; it does not require network-side operators to perform dynamic reorganization, which reduces the burden of network signaling and enables users outside the group to be invited Terminals, the exit mechanism of user terminals outside the group is flexible, and the invited user terminals can actively or passively withdraw from the group call. The above implementation is simple, and it only needs to add an invitation mechanism control strategy on the network side, and add a little signaling interaction between the terminal and the network side.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection.
