Disclosed is a method of using observed traffic pattern data to improve sleep mode efficiency in a radio handset. The radio handset determines quality of service (QoS) requirements of an application currently executing on the radio handset and selects a pre-defined sleep mode mask from among a plurality of pre-defined sleep mode masks wherein the selected pre-defined sleep mode mask provides the closest available match in terms of sleep/listen pattern to the QoS requirements. The traffic pattern data between the radio handset and a serving basestation is observed while under the initial sleep/listen pattern of the selected pre-defined sleep mode mask or the reactivated sleep/listen pattern after sleep mode deactivation. An alternate sleep mode mask is created based on the observed traffic pattern data between the radio handset and the serving base station wherein the alternate sleep/listen pattern is better suited to the actual traffic pattern than the initial sleep/listen pattern of the selected pre-defined sleep mode mask or the reactivated sleep/listen pattern after sleep mode deactivation.

A portable communication device including a first wireless transceiver operable under a first communication protocol for transmitting and receiving signals and a second wireless transceiver operable under a second communication protocol for transmitting and receiving signals and a method for controlling transmission of signals from an access point to the first wireless transceiver by limiting transmission of information from the associated access point to the first wireless transceiver to time slots or sub-frames associated with the second wireless transceiver in which the second wireless transceiver does not transmit.

Disclosed is a method of selectively skipping one or more listen windows during power saving (i.e., sleep mode) operation in a multi-mode radio handset capable of operating on a plurality of radio access networks (RANs). A multi-mode radio handset signals a base station to which it is currently in communication to request that one or more listen windows be skipped considering the delay and jitter requirements of the most time critical application currently running. The request includes data defining a different listen and sleep window sequence. The multi-mode radio handset receives an acknowledgment from the base station indicating that the request has been granted. The acknowledgement includes a start frame parameter that defines when the different listen and sleep window sequence will begin. Upon completion of the different listen and sleep window sequence, the multi-mode radio handset reverts back to the original alternating sequence of listen and sleep windows.
