FIELD: physics; communication.
SUBSTANCE: invention relates to half-duplex radio communication in a cellar network (PoC). A method is invented, which provides for a PoC box service, and transmits service identification information using standard session initiation protocol (SIP), session description protocol (SDP), configuration access protocol (XCAP) and password authentication protocol (PAP) for compatibility with traditional PoC technology, when processing a call for session establishment, using a PoC box. The method also stores only pre-specified multimedia data in the PoC box, in accordance with the type of multimedia data, transmitted taking into account properties of the PoC multimedia session.
EFFECT: provision for compatibility with traditional PoC technology, when processing a call for session establishment using a PoC box.
