FIELD: communications engineering; specialized control channel servicing transmission. SUBSTANCE: for the purpose use is made of Walsh codes and quasi-orthogonal codes. In order to transmit servicing, new base station whereto call is conveyed informs servicing base station about available quasiorthogonal code in case new base station has no available Walsh codes. Servicing base station sends message concerning direction of servicing transmission to mobile station and the latter establishes communication with new base station by means of quasiorthogonal code incorporated in servicing transmission direction message. EFFECT: enhanced capacity of system. 12 cl, 5 dwg
