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.

Claims

1. A method of simultaneously transmitting GPRS/EDGE packet data and circuit-switched voice data along a dedicated GSM voice traffic channel, comprising the steps of:

determining whether the circuit-switched voice data is available to be transmitted along the traffic channel;

determining whether a silence descriptor frame must be sent along the traffic channel in response to circuit-switched voice data not being available; and

transmitting an associated GPRS/EDGE data frame along the traffic channel between occurrences of the circuit-switched voice data and the silence descriptor frame.

2. The method of claim 1, further comprising the steps of:

determining whether a right to transmit on a previously assigned associated GSM/EDGE data only timeslot in a current TDMA frame has been granted; and

transmitting on the associated timeslots.

3. The method of claim 1, further comprising the step of associating and controlling a voice timeslot and data timeslots, wherein the data timeslots are firmly associated with each other and with the voice timeslot.

4. A communication system, comprising:

a base station subsystem; and

a mobile station receiving and transmitting circuit-switched voice data and packet-switched data along a traffic channel to the base station subsystem, wherein the mobile station transmits packet-switched data to the base station subsystem and receives packet-switched data from the base station subsystem during frame periods occurring at associated timeslots between voice and signaling frames and silence descriptor frames of discontinuous transmission and discontinuous reception operations between the mobile station and the base station subsystem.

5. The communication system of claim 4, further comprising an assignment control logic component layer informing the mobile station of assignment of the associated timeslots.

6. The communication system of claim 4, wherein packet-switched data is transmitted and received on the same circuit-switched voice timeslot during discontinuous transmission and discontinuous reception operations as circuit-switched data, and transmission by the mobile station is governed by an uplink timeslot assignment and availability of time in which to send data in discontinuous transmission operation.

7. The communication system of claim 4, further comprising:

a physical layer; and

a medium access controller layer organizing transmission and reception of packet-based information onto and from the physical layer, including logic by which the mobile station is informed of a right to transmit.

8. The communication system of claim 4, wherein the associated timeslots include a voice timeslot and data timeslots, and wherein the data timeslots are firmly associated with each other and with the voice timeslot.

9. The communication device of claim 4, wherein circuit-switched voice data and packet-switched data are streamed in the discontinuous transmission and discontinuous reception operations between the voice and signaling frames and silence descriptor frames are located in a first timeslot, and packet-switched data is located in one or more firmly associated additional timeslots.

10. A communication system, comprising:

a base station subsystem;

a mobile station receiving and transmitting circuit-switched voice data and packet-switched data along a traffic channel to the base station subsystem, wherein the mobile station transmits packet-switched data to the base station subsystem and receives packet-switched data from the base station subsystem during frame periods occurring at associated timeslots between voice and signaling frames and silence descriptor frames of discontinuous transmission and discontinuous reception operations between the mobile station and the base station subsystem;

a physical layer; and

a medium access controller layer organizing transmission and reception of packet-based information onto and from the physical layer, including logic by which the mobile station is informed of a right to transmit.

11. The communication system of claim 10, further comprising an assignment control logic component layer informing the mobile station of assignment of the associated timeslots.

12. The communication system of claim 10, wherein packet-switched data is transmitted and received on the same circuit-switched voice timeslot during discontinuous transmission and discontinuous reception operations as circuit-switched data, and transmission by the mobile station is governed by an uplink timeslot assignment and availability of time in which to send data in discontinuous transmission operation.

13. The communication system of claim 10, wherein the associated timeslots include a voice timeslot and data timeslots, and wherein the data timeslots are firmly associated with each other and with the voice timeslot.

14. The communication device of claim 10, wherein circuit-switched voice data and packet-switched data are streamed in the discontinuous transmission and discontinuous reception operations between the voice and signaling frames and silence descriptor frames are located in a first timeslot, and packet-switched data is located in one or more firmly associated additional timeslots.
