It should be noted that, in the emergency group call establishment method according to the embodiment of the present application, the preset backup channels for emergency call are utilized to enable the terminals in different areas without association to establish signaling communication carriers.
In some embodiments, the group call setup request further includes preset target parameters, and after broadcasting the signaling information to the passive terminal through the backup channel, the following steps are further implemented:
And step 21, determining a time threshold value for allowing the passive terminal to access the active channel based on the preset target parameters.
In this embodiment, the preset target parameters include, but are not limited to, time for emergency group call setup operation, and the preset target parameters are preset values when the emergency group call function is started, and the time for emergency group call setup operation is limited by the preset values, and in the corresponding time range, the passive terminal meeting the set conditions is allowed to access the active channel, so as to establish a call with the active terminal.
Step 22, starting from the first passive terminal to perform wireless setting and access the active channel, recording the switching time of the passive terminal to access the active channel.
In the embodiment, the switching time of the passive terminal to access the active channel is recorded through the timer, and when the timing is over, the corresponding passive terminal is not allowed to access the active channel.
And step 23, when the switching time is greater than the time threshold, sending termination signaling information for terminating the corresponding passive terminal to access the active channel to the active terminal.

Determining a time threshold value allowing the passive terminal to access the active channel based on the preset target parameters in the steps 21 to 23, starting from the first passive terminal to perform wireless setting and access the active channel, recording the switching time of the passive terminal to access the active channel, and sending termination signaling information for terminating the corresponding passive terminal to access the active channel to the active terminal when the switching time is greater than the time threshold value, so as to terminate the emergency group call function after the preset target is met.
In some embodiments, the data encapsulation formats corresponding to the group call setup request, the signaling information, and the termination signaling information all include a short message format.
In this embodiment, the active terminal sends the group call establishment request to the transfer station, the transfer station sends the signaling information to the passive terminal through the backup channel, and the transfer station sends the termination signaling information to the active terminal all in the form of short messages.
In some of these embodiments, before establishing a connection with the passive terminal over the backup channel, the following steps are also implemented:
Step 31, at least the first channel frequency, the first channel time slot and the first channel color code corresponding to the backup channel are obtained from the backup channel information.
In this embodiment, channel switching is achieved by performing channel modification based on wireless setup parameters of the corresponding channel, such as channel frequency, channel time slot, and channel color code.
Step 32, based on the first channel frequency, the first channel time slot and the first channel color code, a channel modification is performed to switch to the backup channel.
And based on the first channel frequency, the first channel time slot and the first channel color code, carrying out channel modification to switch to the backup channel, thereby realizing switching of the transfer station to the backup channel, enabling the transfer station to be connected with a passive terminal waiting for the backup channel through the backup channel and sending signaling information to the passive terminal, thereby building a communication ring under the abnormal frequency condition in a short time and realizing temporary set-up of new group calling under the emergency condition.

In this embodiment, after receiving the corresponding signaling information, the passive terminal cannot directly modify the configuration information based on the signaling information, and needs to authenticate according to the dynamic authorization code carried in the signaling information, that is, decode the dynamic authorization code to obtain the corresponding authentication key, and send the authentication key as the corresponding authentication response to the relay station, and send the authentication key to the active terminal through the active channel by the relay station, so that the active terminal determines whether the passive terminal decodes correctly after receiving the authentication response, and then sends the response to the authentication result to the relay station through the active channel, and after receiving the authentication response information, the relay station sends the authentication response information to the passive terminal through the backup channel, so that the passive terminal is definitely allowed to access the active channel.
And after the authentication response is sent to the active terminal through the active channel, the authentication response information sent by the active terminal is received, so that the forwarding of the authentication signaling between the passive terminal and the active terminal is realized, thereby ensuring that the passive terminal establishing the emergency group call with the active terminal is the passive terminal with the intention of requesting to establish the emergency group call, and ensuring the security of group call establishment.
Fig. 2 is a flowchart of another emergency group call setup method according to an embodiment of the present application. As shown in fig. 2, an embodiment of the present application provides an emergency group call establishment method, applied to an active terminal, including the following steps:
Step S201, after confirming that the passive terminal has an access intention of requesting to establish the emergency group call, sending a group call establishment request to a relay station through an active channel corresponding to the current group call communication, wherein the group call establishment request carries backup channel information and signaling information corresponding to the active channel, and the relay station is used for broadcasting the signaling information to the passive terminal through the backup channel after establishing connection with the passive terminal through the backup channel corresponding to the backup channel information.
In this embodiment, the active terminal is a terminal that starts an emergency group call function when the corresponding terminal wants to access a communication configuration environment corresponding to an active channel to which the active terminal is connected, while the terminal that is actually active wants to access is a passive terminal in this embodiment, before the active terminal starts the emergency group call function, the passive terminal and the active terminal transmit corresponding access intention to the active terminal in a direct or indirect manner, that is, both sides have achieved the intention of establishing the emergency group call, after the active terminal definitely determines the corresponding access intention, the active terminal starts the emergency group call function, and transmits an establishment request to a transfer station through an active channel corresponding to a current communication configuration environment of the active terminal, so that the transfer station switches to a backup channel corresponding to backup channel information carried in the group call establishment request after receiving the group call establishment request, then establishes connection with the passive terminal that wants to access the active terminal through the backup channel, and then transmits signaling information carried in the establishment request and used for characterizing the communication configuration environment of the active channel to the terminal along the backup channel to the passive terminal, thereby realizing the transmission of the corresponding communication configuration parameters of the group call.
In this embodiment, the intention of the passive terminal and the active terminal to achieve correspondence is not established through the communication channel and the communication environment established by the emergency group call in the applied embodiment, but other approaches are adopted to achieve the intention of the two parties to achieve correspondence, for example, the intention of the two parties to establish the corresponding emergency group call can be negotiated through the leader in the passive terminal and the leader in the active terminal to perform other communication modes, and it should be understood that the intention of the two parties to achieve correspondence is not a limitation on the establishment of the emergency group call in the applied embodiment, and the intention of the two parties to achieve correspondence is a precondition for executing the emergency group call function in the applied embodiment.

In this embodiment, before the active terminal and the passive terminal establish a connection, the active terminal needs to verify the decoding result of the dynamic authorization code carried in the signaling information by the passive terminal, that is, verify the authentication response, so as to receive the authentication response forwarded by the relay station, after verifying the authentication response, send the corresponding authentication response information to the relay station, and then the relay station sends the corresponding authentication response information to the passive terminal, so that the passive terminal determines whether the passive terminal is allowed to access the active channel according to the received result of the authentication response information, and when the passive terminal determines that the passive terminal is allowed to access the active channel, the passive terminal performs wireless setting based on the signaling information to access the active channel after finishing channel configuration information modification.
Step S203, when the passive terminal accesses the active channel, a call is established with the passive terminal.
In this embodiment, the signaling information is information describing corresponding wireless setting parameters of an active channel for group call communication of the active terminal, and at least includes one or more of a channel time slot, a channel color code, and a channel frequency point, and by modifying the time slot, the color code, and the frequency point of the corresponding channel to be consistent with related parameters corresponding to the signaling information, the passive terminal is executed to access the active channel, and a call with the active terminal is established.
The method comprises the steps of S201 to S203, after receiving the access intention of the passive terminal requesting to establish the emergency group call, sending a group call establishment request to the relay station through an active channel corresponding to the current group call communication, wherein the group call establishment request carries backup channel information and signaling information corresponding to the active channel, receiving an authentication response sent by the relay station through the active channel, and sending authentication response information of the authentication response to the relay station, so that the passive terminal can perform wireless setting based on the signaling information after receiving the authentication response information sent by the relay station, and access the active channel, wherein the authentication response information is used for representing whether the active terminal is allowed to access the active channel, and when the passive terminal accesses the active channel, establishing a call with the passive terminal, thereby solving the problems of high difficulty in implementing interworking of configuration environment and low group call establishment efficiency when establishing a new group call in the related technology, and realizing the beneficial effects of temporarily establishing the new group call by establishing the communication environment under the abnormal frequency condition in a short time under the emergency condition.
In some of these embodiments, after the call is established with the passive terminal, the steps of receiving termination signaling information sent by the transfer station and terminating the call establishment with the passive terminal that does not access the active channel based on the termination signaling information are also performed.
