FIELD: information technologies.
SUBSTANCE: response registration message REG-RSP is generated, which contains field "type", field "length" and field "combined connection facility identifier (CFI)". Field "combined CFI" comprises combined CFI. Combined CFI is formed with application of new CFI and old CFI, which are assigned to subscriber terminal device. Fields "type" and "length" comprise, accordingly, information about type and length of combined CFI. Generated message REG_RSP is transmitted to subscriber terminal device, which is target object of service transfer. Message is generated with traffic availability indicator (TRF_IND), which contains at least one field "short MCFI" (MCFI - the main identifier of connection facility), in which short MCFI is placed. Short MCFI is formed by means of specified number of bits from total number of bits that reflect MCFI of required subscriber terminal device, which should receive information that indicates availability of traffic. Then broadcasting transmission of generated message TRF_IND is done.
EFFECT: higher efficiency of control messages transfer.
