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.
Claims11
A method for reducing power consumption in a first wireless device comprising:
- synchronizing the first device with a wireless network so that the first device may wake up at predetermined time intervals to determine whether the first device has been identified for receipt of message data over the network;
- providing a message listing not having message data and comprising at least one destination identifier and an associated message pointer;
- detecting whether the message listing includes any destination identifiers that correspond to the first device;
- and
- receiving the message of the message pointer when a destination identifier of the first device is detected.
A message listing for use in a wireless network comprising:
- a count of identifiers listed in the message listing;
- at least one destination identifier indicative of a device to whom a message has been sent to;
- and
- a message pointer for each destination identifier indicative of where a device to whom a message has sent may obtain the message data intended for said device and wherein the message listing does not include the message data.
A system for optimizing power resources in wireless devices comprising:
- at least one radio network controller (RNC);
- at least one base station (BS);
- wherein the RNC and BS are adapted so as to periodically provide a message listing comprising at least one destination identifier and associated message pointer, the message listing not comprising message data;
- and
- a plurality of wireless devices adapted to receive the provided message listing and obtain any messages indicated by the message listing as being directed to them.
A wireless device configured to receive message data over a wireless interface comprising:
- a processor for analyzing a message listing comprising;
- a count of identifiers listed in the message listing;
- at least one destination identifier indicative of a device to whom a message has been sent to;
- and
- a message pointer for each destination identifier indicative of where a device to whom a message has sent may obtain the message data intended for said device and wherein the message listing does not include the message data.
