Problems solved by technology

Although most devices only occasionally have transmissions directed to them, the device must remain awake throughout the notification period
This means that many devices consume power throughout the notification period, even when there is usually no data for them

Embodiment Construction

[0018] Preferred embodiments of the present invention will be described with reference to the drawings, wherein like numerals indicate like components.

[0019] first reference figure 1 , which shows a list of 10 messages. Wireless devices are typically synchronized with the network so that the devices know to wake up during predetermined periods and check for any messages intended for them. To save battery, the wireless device preferably not only sleeps between predetermined periods, but spends as little time as possible determining whether there are messages for the device. Wireless devices typically determine whether they are the intended recipient of a message by checking a list of messages. A message list in the prior art includes not only a number of identifiers representing the destination of each message contained in the list and a count of the number of messages therein, but also the messages themselves. Including the message itself in the message list increases th...

Abstract

A method and system is disclosed for a device to quickly determine if data is being sent to it. If no data is being sent to the device, the device may return to a sleep mode so as to conserve energy. The present invention includes organizing and transmitting, one at a time, all device destination identifiers. If a message listing search indicates that no message is being sent for a device, the device can continue with any other activity that needs servicing, or if no other activity is pending, it may shut down to conserve power until the next wake up period arrives. If the search returns a positive indication, the count value when the identifier is found can be used to determine the location of the pointer to the message.

Description

[0001] This application is a divisional application of a Chinese invention patent application with the filing date of April 29, 2003, the application number of 03809806.7, and the title of "Method and System for Optimizing Power Resources in Wireless Devices". technical field [0002] The invention relates to the field of wireless communication. More particularly, the present invention relates to optimization of power resources of wireless devices in wireless communication systems. Background technique [0003] Portable electronic devices often run out of batteries. Data transmitted to the device is often short (eg, emails, instant messages, digital updates, status changes). When the devices look for transmissions directed to them, the power consumed by the devices often exceeds the power required to receive such transmissions. Also, the devices typically only occasionally have transmissions directed to them. Although most devices only occasionally have transmissions dire...
