Patent ID: 8467323

Claim:
A method in a communication device providing data services over a packet access radio interface, the method comprising: monitoring a control channel for signalling messages for data packets for the communication device; receiving data packets for a data service of a first type with a first periodicity; receiving data packets for the data service of a second type with a second periodicity, the second periodicity being greater than the first periodicity; and selecting at the communication device to stop monitoring the control channel for signalling messages for a period of time in response to detecting by the communication device a data packet of the second type received by the communication device; wherein monitoring a control channel comprises monitoring a control channel by elements of a receiving section of the communication device operating in a signalling monitoring mode and wherein selecting comprises switching the elements of the receiving section to a non-signalling monitoring mode for the period of time in response to detecting the data packet of the second type, wherein during the non-signalling monitoring mode the elements are arranged to not monitor the control channel for signalling messages.
