ABSTRACT:
A system and method in a client device (22) for controlling the power within the client device (22). The client device (22) has a network access device (30, 130), a programmable timer (48), and a controller (42). The network access device (30, 130) has at least a powered state and a power-off state. The programmable timer (48) operates the network access device (30, 130) in the powered state. The controller (42) is coupled to the programmable timer (48) and is capable of providing a time period for operating the network access device (30, 130) in the powered state. The controller (42) determines the time period based on a discontinuous reception (DRX) parameter obtained from the network access device (30, 130). The network access device (130) may include a transceiver. The network access device (30) may also include a transceiver and a controller. There are also methods of operating the client device (22) to control the power within the device.
