Abstract

A method and apparatus of transmitting and receiving data in a mobile communication system is disclosed. The method of transmitting and receiving data in a mobile communication system comprises receiving control information related to transmission and reception from a transmitting side, determining at least one of power saving parameter information of a talk spurt and a silence period from the control information related to transmission and reception, and receiving data from the transmitting side by applying the power saving parameter information depending on the talk spurt and the silence period. According to the above method, unnecessary data reception is not performed in the silence period.

Claims

1-20. -20. (canceled)

21. Method for transmission or reception service data in wireless access system, the method comprising:

transmitting, from a terminal to a base station, a Dynamic Service Addition request (DSA-REQ) message in order to negotiate parameters used at scheduling for transmission or reception of the service data with the base station;

receiving a Dynamic Service Addition response (DSA-RSP) message including a primary interval and a secondary interval for the service data from the base station; and

transmitting or receiving the service data using the primary interval initially,

wherein interval of the scheduled service data is switched between the primary interval and the secondary interval.

22. The method according to claim 21, wherein the switch between the primary interval and the secondary interval is performed by transmitting a bandwidth request message from the terminal to the base station.

23. The method according to claim 21, wherein the switch between the primary interval and the secondary interval is performed when the secondary interval is defined during the parameter negotiation process.

24. The method according to claim 21, wherein the switch between the primary interval and the secondary interval is performed when a characteristic of the scheduled service data is changed.

25. The method according to claim 24, wherein the characteristic of the scheduled service data is changed when an interval in which the scheduled service data is transmitted is changed from talk spurt to silence period or from silence period to talk spurt.

26. The method according to claim 21, wherein the DSA-RSP message further comprises a Maximum Sustain Traffic Rate parameter defining a peak information rate of the scheduled service data and a Request/Transmission Policy parameter specifying certain attributes for the associated service flow.

27. The method according to claim 21, wherein the scheduling is a grant and polling scheduling.

28. The method according to claim 27, wherein the DSA-RSP message further comprises a primary size parameter and a secondary size parameter for the grant and polling scheduling, and

wherein a size parameter used at the grant and polling scheduling is switched between the primary size parameter and the secondary size parameter.

29. Method for transmission or reception service data in wireless access system, the method comprising:

receiving, by a base station from a terminal, a Dynamic Service Addition request (DSA-REQ) message in order to negotiate parameters used at scheduling for transmission or reception of the service data with the terminal;

transmitting a Dynamic Service Addition response (DSA-RSP) message including a primary interval and a secondary interval for the service data to the terminal; and

receiving or transmitting the service data using the primary interval initially,

wherein interval of the scheduled service data is switched between the primary interval and the secondary interval.

30. The method according to claim 29, wherein the switch between the primary interval and the secondary interval is performed by transmitting a bandwidth request message from the terminal to the base station.

31. The method according to claim 29, wherein the switch between the primary interval and the secondary interval is performed when the secondary interval is defined during the parameter negotiation process.

32. The method according to claim 29, wherein the switch between the primary interval and the secondary interval is performed when a characteristic of the scheduled service data is changed.

33. The method according to claim 32, wherein the characteristic of the scheduled service data is changed when an interval in which the scheduled service data is transmitted is changed from talk spurt to silence period or from silence period to talk spurt.

34. The method according to claim 29, wherein the DSA-RSP message further comprises a Maximum Sustain Traffic Rate parameter defining a peak information rate of the scheduled service data and a Request/Transmission Policy parameter specifying certain attributes for the associated service flow.

35. The method according to claim 29,

wherein the scheduling is a grant and polling scheduling, and

wherein the DSA-RSP message further comprises a primary size parameter and a secondary size parameter for the grant and polling scheduling, and

wherein a size parameter used at the grant and polling scheduling is switched between the primary size parameter and the secondary size parameter.

36. A terminal for transmission or reception service data in wireless access system, the terminal comprising:

a control module adapted for;

transmitting, from a terminal to a base station, a Dynamic Service Addition request (DSA-REQ) message in order to negotiate parameters used at scheduling for transmission or reception of the service data with the base station;

receiving a Dynamic Service Addition response (DSA-RSP) message including a primary interval and a secondary interval for the service data from the base station; and

transmitting or receiving the service data using the primary interval initially,

wherein interval of the scheduled service data is switched between the primary interval and the secondary interval.

37. The terminal according to claim 36, wherein the switch between the primary interval and the secondary interval is performed by transmitting a bandwidth request message from the terminal to the base station.

38. The terminal according to claim 36, wherein the switch between the primary interval and the secondary interval is performed when the secondary interval is defined during the parameter negotiation process.

39. The terminal according to claim 36, wherein the switch between the primary interval and the secondary interval is performed when a characteristic of the scheduled service data is changed.

40. The terminal according to claim 39, wherein the characteristic of the scheduled service data is changed when an interval in which the scheduled service data is transmitted is changed from talk spurt to silence period or from silence period to talk spurt.

41. The terminal according to claim 36, wherein the DSA-RSP message further comprises a Maximum Sustain Traffic Rate parameter defining a peak information rate of the scheduled service data and a Request/Transmission Policy parameter specifying certain attributes for the associated service flow.
