System and method for controlling the power in a wireless client device
First Claim
1. A client device comprising:
- a network access device that receives messages over a communication channel, the network access device having a powered state and a power-off state;
a programmable timer for operating the network access device in the powered state; and
a controller that is in communication with the programmable timer and capable of providing a time period for operating the network access device in the powered state, the controller determining the time period based at least on a given value of discontinuous reception parameter obtained from the network access device and an amount of current drawn by the network access device at the given value of discontinuous reception parameter.

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.

14. A client device that is embedded in a vehicle, the client device comprising:
-
a network access device having at least a powered state and a power-off state, the powered state allowing the network access device to receive messages over a communication channel, the power-off state not allowing the network access device to receive messages over the communication channel; and a controller that determines a time period for the network access device to be in the powered state, the time period defining a length of time after an ignition switch in the vehicle is turned off, wherein the controller determines the time period based at least on a given value of discontinuous reception parameter obtained from the network access device and an amount of current drawn by the network access device at the given value of discontinuous reception parameter. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method in a client device, the client device having a network access device, a programmable timer, and a controller, the method comprising the steps of:
-
obtaining a discontinuous reception parameter from a network; determining a time period for operating the network access device in a powered state based at least on a given value of the discontinuous reception parameter and an amount of current drawn by the network access device at the given value of discontinuous reception parameter; sending the time period to the programmable timer; and operating the network access device in a powered state during the time period. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
