Discontinuous reception/transmission for mobile communication system

A method of controlling discontinuous reception (DRX) cycles in a mobile radio communications device, comprising the steps of monitoring the number of consecutive DRX periods within which no data is received, monitoring the number of consecutive DRX periods within which data is received, and varying the said DRX responsive to the result of said monitoring.

A method of controlling discontinuous transmission (DTX) cycles within a mobile radio communications network device, comprising the steps of monitoring the number of consecutive DTX periods within which no data is transmitted, monitoring the number of consecutive DTX periods within which data is transmitted, and varying the said discontinuous transmission cycle responsive to the result of said monitoring.

A mobile radio communications device arranged for operation in a discontinuous reception mode exhibiting discontinuous reception cycles and including means for monitoring the number of consecutive discontinuous reception periods within which no data is received, means for monitoring the number of consecutive discontinuous reception periods within which data is received, and the device being arranged to vary the said discontinuous reception cycles responsive to the result of the said monitoring.

A mobile radio communications network device arranged for operation within a discontinuous transmission mode exhibiting discontinuous transmission cycles and including means for monitoring the number of consecutive discontinuous transmission periods within which no data is transmitted, means for monitoring the number of consecutive discontinuous transmission periods within which data is transmitted, and the device further being arranged to varying the said discontinuous transmission cycles responsive to the result of the said monitoring.
