FIELD OF INVENTION
The invention relates to power saving in wireless devices, and more particularly to providing a method of waking up a wireless device from deep sleep through an internet enabled wireless network.
BACKGROUND
The wireless device/user equipment may be allowed to periodically switch off its receiver for some time before it has to listen again to the control channel to see if the network has new data for the wireless device. On and off times can be configured dynamically depending on the wireless device 's activity.
When the network configures DRX for a wireless device, the network defines the value for a timer that starts running after each data block has been sent. If no data was received during the short DRX cycle mode, the wireless device implicitly enters the long DRX cycle which is much more power efficient but further increases latency time. The wireless device has to wake up based on DRX timers (short and long DRX cycle) and read the paging. Hence, a sleep period that is too long may result in unnecessary or even unacceptable levels of delay in receiving a paging signal. On the other hand, a sleep period that is too short may significantly reduce the operating life of the device between recharges (i.e., by depleting battery power by waking up too frequently).
Hence, there is a need of a new DRX cycle other than short and long DRX cycle which can keep the wireless device in sleep mode for longest duration or say unlimited amount of time.

In other words, a method is required to keep the wireless device in sleep mode till there is no paging for the wireless device. Also, there is a need for a mechanism to wake up wireless device from sleep mode via another wireless network say WiFi network or any other alternative medium.
The present invention is intended to solve the problems set forth above.
