FIELD: radio engineering, communication.
SUBSTANCE: techniques for managing dual-channel wireless devices are described. A dual-channel wireless device may have a first transceiver operating to transmit control information over a data channel using a packet-switched network. The dual-channel wireless device may further have an enhanced call module communicatively connected to the first transceiver, the enhanced call module having a two-way user agent operating to establish a session between the two-way user agent and a call terminal using the control information. The dual-channel wireless device may also have a second transceiver operating to transmit voice information over a voice channel using a circuit-switched network during the session.
EFFECT: high channel capacity.
