FIELD: mobile systems of telephone communication. SUBSTANCE: process of synchronization of connections while communicating in mobile communication system incorporating at least one base station and mobile stations which communicate over direct communication channel divided into frames includes operations of transmission of registration report by first mobile station to base station with message of desire to function under mode of double control over transmission in control channel, of transmission of information on particular control channel of base station and information on synchronization to first mobile station, of switching over of first mobile station to mode of double control over transmission for communication both over direct communication channel and over assigned control channel in the course of time specified with the use of above- mentioned information on synchronization. Mobile communication system incorporates one base station as minimum, mobile stations, transmission facility to send information on particular control channel and on synchronization related mentioned control channel. Technical result of invention consists in provision for use of mode of double control over transmission of mobile station which operates over direct communication channel and communicates under mode double control over transmission. EFFECT: enhanced reliability of communication. 12 cl, 9 dwg
