FIELD: information technologies.
SUBSTANCE: alarm frame and a voice frame are sent to a receiving device in a system of mobile communication CDMA, having a network ALL-IP, heading information is sent to the receiving device by means of the alarm frame in process of setting a call to a user's request with a call attempt, and the voice frame is sent to the receiving device. When organising a virtual channel and requesting MPLS-traffic data passage, a request of MTU parameter is generated, afterwards a flag of data packet IP fragmentation ban is set. Further to assess the possibility to realise the transfer, a test command "ping" is used with a request of a ban on fragmentation of the packet with the selected length. Upon positive completion of the "ping" command, a length of the frame is generated to transfer a codec, which is multiple to the length of the data transfer packet during communication, defined by the minimum MTU of the network on the way of the transfer, upon negative completion, a new request is generated for passage of MPLS-traffic, and procedure of verifying the possibility of transfer is repeated.
EFFECT: reduced number of erroneously synthesized segments of a voice signal.
