Description

Method and device for processing call application

Technical field

The present invention relates to the field of communications, and in particular to a method and apparatus for processing a call right application.

Background technique

Currently, based on the cluster communication of the Long Term Evolution (LTE) technology, the signaling between the cluster group call and the cluster core network needs to be forwarded through the LTE core network. The call right application of the trunking communication group needs to first send the call right application information to the LTE core network, and then the LTE core network forwards to the cluster core network, and finally the cluster core network performs the voice right authorization judgment. The cluster core network can decide whether to grant the right to the terminal according to whether the current cluster group call right is occupied or not. If the call request needs to be queued, the base station transmits the data (including signaling) between the core network and the terminal for a period of time, and the user is inactive, causing the base station to initiate release, and the bearer established by the terminal and the core network is also completed. It will be released, which means that the user inactivity occurs during the queuing process of the group call right request, and the terminal finally fails to apply for the right to speak. If there are many terminals connected to the group call, and everyone wants to apply for the right to call, there may be cases where the application for multiple calls fails.

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

1 is a flow chart of a method of processing a call right application in accordance with an embodiment of the present invention. As shown in FIG. 1, the processing method of the call authorization application may include the following processing steps:

Step S102: determining that the terminal waits for the right to apply for the call;

Step S104: The first NAS message is continuously sent to the terminal in the preset duration, where the first NAS message carries the handshake request signaling, and the handshake request signaling is used to keep the application for the terminal right to be released.

Step S106: Receive a second NAS message from the terminal, where the second NAS message carries handshake response signaling.

In the related art, when the terminal cannot apply for the right to speak, the call right application is released, thereby affecting the user experience. In the cluster communication, when the terminal makes a call right application, if the cluster core network decides that the terminal needs to perform group call application right queuing, it can pass the non-access layer (Non-Access- Stratum, referred to as NAS), maintains the handshake mode of the process, so that the application for the right of the terminal is not released, thereby solving the related art that when the terminal cannot apply for the right to speak, the application for the right to be released is released, thereby affecting The user experience problem, when the terminal applies for the right to queue, does not need to apply for the right to call multiple times, and it is easy to apply for the right to speak in a relatively short period of time, thereby improving the user experience.

Preferably, in step S104, continuously sending the first NAS message to the terminal within the preset duration may include the following operations:

Step S1: setting a timer within a preset duration;

Step S2: determining whether the terminal is in the queue waiting state of the dialog right if the timer expires;

Step S3: If yes, continue to send the first NAS message to the terminal;

Step S4: If no, the continuation of the timer is stopped and the sending of the first NAS message to the terminal is stopped.

In a preferred embodiment, if the result of the decision of the cluster core network is that the terminal needs to queue the call right of the applied right, the cluster core network starts a periodic handshake timer (equivalent to the above timer), and directly transmits the NAS. The message forwards the handshake request signaling to the terminal via the LTE core network and the base station. After receiving the handshake request signaling, the terminal sends the handshake response signaling to the cluster core network through the base station and the LTE core network through the uplink direct transmission NAS message.

If the periodic handshake timer expires and the terminal is still in the call request queue, the cluster core network continues to send the handshake request signaling to the terminal until the terminal obtains the call right or the terminal initiates the release, and then stops the periodic handshake timer.

At the same time, it should be noted that the length of the user inactivity timer (equivalent to the preset duration) is greater than the length of the periodic handshake timer, and the lengths of the two timers are configurable. In this way, the length of the user inactivity timer and the periodic handshake timer can be reasonably set according to the actual situation, and the terminal does not finally apply for the call right failure due to the user inactivity timer being timed out.

Preferably, in step S102, determining that the terminal dialog right is queued may include the following steps:

Step S5: Receive a third NAS message from the terminal, where the third NAS message carries the call right application information.

Step S6: In the case that it is determined that the terminal is currently unable to use the call right, the fourth NAS message is returned to the terminal, where the fourth NAS message carries the decision result of the terminal dialogue right to wait in the queue.

In the preferred implementation process, the cluster core network currently cannot use the call right in the decision terminal to meet the following conditions:

Condition 1. Determining that the right to speak has been occupied by other terminals than the terminal; and,

Condition 2: It is determined that the priority of the terminal to obtain the right to speak is lower than the priority of other terminals.

In a preferred embodiment, when the non-speech terminal initiates the group call right application, the cluster core network determines that the group call rights have been authorized to other terminals, and the priority of the terminal that applies for the right and the terminal with the right to call Compared with the lower priority, the result of the cluster core network decision may be to actively delay the failure of the voice authorization or queue the call, and then the cluster core network passes the direct decision of the NAS message to the LTE core network. The base station forwards to the terminal.

Preferably, after receiving the second NAS message from the terminal in step S106, the method may further include the following steps:

Step S7: If it is determined that the terminal acquires the right to call within the preset duration, the cluster-specific bearer between the terminal and the terminal is established;

Step S8: The fifth NAS message is sent to the terminal by using the cluster dedicated bearer, where the fifth NAS message carries the authorization information for granting the right to the terminal.

In a preferred embodiment, if the terminal finally obtains the right to speak, the cluster core network stops the periodic handshake timer and establishes a cluster-specific bearer between the UE and the cluster core network. The cluster core network may send the NAS message carrying the authorization information to the terminal via the LTE core network and the base station. Then, the terminal may send the NAS message carrying the authorization response information to the cluster core network via the base station and the LTE core network.

The above preferred implementation process will be further described below in conjunction with the preferred embodiment illustrated in Figures 2 and 3.

The preferred embodiment of the present invention provides a LTE Push-to-Talk (PTT) system for resolving a group call-to-call queuing method, which mainly involves a cluster core network and a terminal supporting the cluster service.

Step S218 - Step S220: After receiving the handshake request signaling, the terminal returns an uplink NAS direct transmission message carrying the handshake response signaling to the cluster core network via the base station and the LTE core network.

Step S222 - Step S228: If the handshake timer expires and the terminal has not acquired the right to speak and does not initiate release, the cluster core network will perform a new round of handshake with the terminal.

Step S230: If the terminal finally obtains the right to call, the cluster core network stops the periodic handshake timer, and establishes a cluster dedicated bearer between the UE and the cluster core network.

Step S232-Step S234: The cluster core network sends the NAS message carrying the authorization information to the terminal via the LTE core network and the base station.

Step S236-Step S238: The terminal sends the NAS message carrying the authorization response information to the cluster core network via the base station and the LTE core network.

Step S304: The LTE core network determines that it is a clustered NAS message, performs only security processing, and then transparently transmits the packet to the cluster core network.

Step S306: After receiving the call requesting NAS message, the cluster core network authenticates the user, if the other users of the current group call have occupied the right to call and the priority of the terminal is lower than the priority of the terminal having the right to speak.

Step S314: Step S316: After receiving the handshake request signaling, the terminal returns an uplink NAS direct transmission message carrying the handshake response signaling to the cluster core network via the base station and the LTE core network.

Step S318 - Step S324: If the handshake timer expires, the terminal has not acquired the call right and the release is not initiated, the cluster core network and the terminal perform a new round of handshake.

Step S326: The terminal finally obtains the right to call, and then the cluster core network stops the periodic handshake timer, and establishes a cluster dedicated bearer between the UE and the cluster core network.
