FIELD: physics; communications.
SUBSTANCE: invention relates to communication systems, particularly to combinational channel and packet switched networks. The said technical outcome is achieved due to that, combinational communication networks make possible simultaneous communication over communication networks of different types between subscriber equipment of party A and party B. A communication session which contains channel switched calls (CS) and one or more packet switched (PS) sessions can be simultaneously used in different types of communication networks with respect to the same subscriber equipment. Channel switched (CS) calls and packet switched (PS) session can be correlated. With respect to searching for packet switching address on a channel switched (CS) partner call, packet switched (PS) network address search is initiated through a channel switching (CS) protocol on a channel switched (CS) communication network. An address search request is sent to the call partner or to a network node which satisfies the said network address request.
EFFECT: more efficient search for network address.
