Media recording method and device of cluster communication

[0023] figure 1 It is a flow chart of a group communication media recording method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of recording group call media, and the method can be executed by a group communication media recording device. The media recording device for communication is configured in the cluster communication server, and the method specifically includes the following steps:

[0024] Step 110, when the group call media recording service is triggered, send a group call media recording request to the media recording server, so as to request the media recording server to allocate a media channel for the group call media to be recorded.

[0025] After the trunking communication group call session is established, the trunking communication server queries the user subscription data to determine whether the user-customized service includes the group call media recording service. If the group call media recording service is i
