Abstract
Apparatus and methods for, among other things, a grouped based reactive service discovery protocol are discussed. In an example, a method can include broadcasting a first group beacon at a group interval using a first station belonging to a first group of stations and broadcasting a service request to the second group during a query interval of the second group. In an example, the first group beacon can include a service update alert configured to alert other members of the first group of an anticipated service request and response event to learn services available from a second group.
Claims20
A method for grouped based reactive service discovery, the method comprising:
- broadcasting a first group beacon at a group interval using a first station belonging to a first group of stations, the first group beacon including a service update alert configured to alert other members of the first group of an anticipated service request and response event to learn services available from a second group, the service update alert including a beginning time for the anticipated service request and response event corresponding to a query interval of the second group;
- and
- broadcasting a service request to the second group during the query interval of the second group.
A method for grouped based reactive service discovery, the method comprising:
- receiving at a first station of a first group of stations a service update alert indicating a beginning time for an anticipated service request and response event to learn services available from a second group of stations;
- switching the first station to a sleep mode to conserve energy;
- waking the first station from the sleep mode at or near the beginning time;
- and
- receiving a service response frame from the second group of stations at the first station.
A wireless communication station configured for grouped based reactive service discovery, the wireless communication device comprising:
- an IEEE 802.11 compatible wireless transceiver configured:
- to receive a service update alert indicating a beginning time for an anticipated service request and response event from a first group of stations;
- to switch the processor to a sleep mode to conserve energy;
- to wake the processor from the sleep mode at or near the beginning time;
- and
- to receive a service response frame from a second group of stations.
A wireless communication station configured for grouped based reactive service discovery, the wireless communication device comprising:
- a processor;
- memory coupled to the processor;
- an antenna;
- and
- an IEEE 802.11 compatible wireless transceiver configured:
- to provide wireless communication of information to be stored into and retrieved from the memory using the antenna;
- to receive a service update alert indicating a beginning time of a query window of an anticipated service request and response event of a first group of stations,
- to switch the processor to a sleep mode to conserve energy;
- to wake the processor from the sleep mode at or near the beginning time;
- and
- to receive a service response frame from a second group of stations during the query window.
The wireless communication station 18, wherein the transceiver is configured:
- to transmit a second service update alert configured to alert other members of the first group of a second anticipated service request and response event to learn services available from a third group of stations, the second service update alert including a beginning time for a query window of the third group;
- to transmit a second service request for service information of the third group during the query window;
- and
- to receive a second service response including the service information of the third group from a station of the third group.
