FIELD: radio engineering, communication.
SUBSTANCE: at the same time the method is provided for fixed network equipment (FNE), in order to control a configuration of three of four and one of four time intervals of a slow associated control channel (SACCH) along a manifold voice channel of the Project 25 (P25) of the Association of official representatives of communication services of public safety authorities (APCO). Knowledge of this configuration both by FNE equipment and radio station makes it possible to alarm unique information in each type of SACCH. In accordance with realisation versions, the procedure makes it possible to control a minimum level (incoming), while there is an independent outgoing (minimum level) (for instance, panel control). This procedure also makes it possible for each radio station to differentiate an incoming control alarm of minimum level from an outgoing identifier (ID) of a calling device. Availability of control of incoming SACCH configuration infrastructure and its transmission to all radio stations assists in proper detection of transmitted configuration from a radio station.
EFFECT: provision of accurate alarm of an ID of a calling device and control information of transmitting radio station transmitters within a wireless communication system.
