FIELD: mobile communication equipment. SUBSTANCE: method involves sequence of operations for double transmission of search call packets in order to find mobile user set in response to call execution command, and establishing synchronization by means of first received search call packet. This results in generation of hopping frequency, switching receiver on and waiting search call packet with hopping frequency. Then method involves transmission of search call acknowledgement packet to calling mobile user set synchronously with second received search call packet. EFFECT: increased precision of synchronization between user sets. 3 cl, 4 dwg
