Abstract
A simplified version of a defined GPRS/EDGE Class A mobile station that incorporates transmission and reception of GPRS/EDGE data during discontinuous transmission and reception modes on a dedicated traffic channel, and that includes a mechanism for streaming GPRS/EDGE data to and from a packet-switched channel, along with optional association of a voice timeslot with one or more GPRS/EDGE data timeslots. GPRS/EDGE packet data and circuit-switched voice data are simultaneously transmitting along a dedicated GSM voice traffic channel by transmitting the GPRS/EDGE packet data between occurrences of circuit-switched voice data and silence descriptor frame data along a dedicated voice traffic channel.
