FIELD: radio engineering, communication.
SUBSTANCE: method of providing communication between mobile devices within a wide area network using IP unicast communication and a wireless local area network using IP multicast communication is characterised by that establishing data communication between a mobile device and a wireless local area network. The method involves receiving a first unicast IP address, joining a multicast group within the wireless local area network and registering with that multicast group using a predetermined multicast IP address as a destination IP address and the first unicast IP address as a source address and disconnecting from data communication within the wireless local area network, releasing the first unicast IP address, establishing data communication between the mobile device and the wide area network, thereby receiving a second unicast IP address and a second IP address for the mobile device within the multicast group.
EFFECT: enabling wireless communication of a portable two-way transceiver with different local area networks without using additional servers.
