Abstract

Method and apparatus for transmitting data from a first communication device to a second communication device, wherein the first communication device can assume at least two communication link states. The data is transmitted by the first communication device when the first communication device is in the first communication link state, as a function of the amount of data to be transmitted via a first jointly used communication channel or via a second jointly used communication channel to the second communication device. The data is transmitted by the first communication device, when the first communication device is in the second communication link state, via a third jointly used communication channel to the second communication device.

Claims

1-23. -23. (canceled)

24. A method for transmitting data from a first communication device to a second communication device, wherein the first communication device can assume at least two communication link states, comprising:

transmitting the data by the first communication device when the first communication device is in the first communication link state, as a function of the amount of data to be transmitted via a first jointly used communication channel or via a second jointly used communication channel to the second communication device; and

transmitting, when the first communication device is in the second communication link state, data via a third jointly used communication channel to the second communication device.

25. The method as claimed in claim 24, wherein at least one of the first communication device and the second communication device is a mobile radio communication device.

26. The method as claimed in claim 24, wherein the first communication device is a communication terminal.

27. The method as claimed in claim 24, wherein the second communication device is a communication network device.

28. The method as claimed in claim 24, wherein the first communication device is a communication network device.

29. The method as claimed in claim 24, wherein the second communication device is a communication terminal.

30. The method as claimed in claim 24, wherein in the first communication link state, the first communication device has set up a signaling communication link and a data communication link to the second communication device.

31. The method as claimed in claim 24, wherein in the second communication link state, the first communication device has set up only a signaling communication link to the second communication device.

32. The method as claimed in claim 24, wherein the jointly used communication channels are jointly used mobile radio channels.

33. The method as claimed in claim 24, wherein the jointly used communication channels are transport channels.

34. The method as claimed in claim 32, wherein the first jointly used communication channel is an uplink shared channel.

35. The method as claimed in claim 34, wherein the first jointly used communication channel is an enhanced uplink shared channel.

36. The method as claimed in claim 33, wherein the second jointly used communication channel is a first random access channel.

37. The method as claimed in claim 33, wherein the third communication channel is a second random access channel.

38. The method as claimed in claim 36, wherein at least one of different time periods and different frequency ranges is/are associated with the second communication channel and with the third communication channel.

39. The method as claimed in claim 33, further comprising:

mapping the data from the first communication channel onto a first jointly used physical communication channel; and

transmitting the data in the first communication channel via the first jointly used physical communication channel to the second communication device.

40. The method as claimed in claim 39, further comprising:

mapping the data from the first communication channel onto a physical uplink shared channel; and

transmitting the data in the first communication channel via the physical uplink shared channel to the second communication device.

41. The method as claimed in claim 33, further comprising:

mapping the data from the second communication channel onto a second jointly used physical communication channel; and

transmitting the data in the second communication channel via the second jointly used physical communication channel to the second communication device.

42. The method as claimed in claim 41, further comprising:

mapping the data from the second communication channel onto a physical random access channel; and

transmitting the data from the second communication channel via the physical random access channel to the second communication device.

43. The method as claimed in claim 41, further comprising:

mapping the data from the third communication channel onto a third jointly used physical communication channel; and

transmitting the data in the third communication channel via the third jointly used physical communication channel to the second communication device.

44. The method as claimed in claim 43, further comprising:

mapping the data from the third communication channel onto a physical random access channel; and

transmitting the data in the third communication channel via the physical random access channel to the second communication device.

45. A communication device, comprising:

a data transmission control unit configured to control transmission of data onto a communication channel and provide at least two communication link states,

wherein, when the data transmission control unit is in a first communication link state, and depending on the amount of data to be transmitted, the data transmission control unit allocates the data to a first jointly used communication channel or to a second jointly used communication channel, and

wherein, when the data transmission control unit is in a second communication link state, the data transmission control unit allocates the data to be transmitted to a third jointly used communication channel; and

a transmission unit configured to transmit the data via the jointly used communication channel to which the data to be transmitted is allocated.

46. A computer program element for transmitting data from a first communication device to a second communication device, in which case the first communication device can assume at least two communication link states which, when the computer program element is in the form of the first communication device, results in the following being carried out:

transmitting the data by the first communication device when the first communication device is in the first communication link state, depending on the amount of data to be transmitted, via a first jointly used communication channel or via a second jointly used communication channel to the second communication device; and

transmitting the data by the first communication device, when the first communication device is in the second communication link state, via a third jointly used communication channel to the second communication device.
