Systems and methods for power efficient discovery of infrastructure services on a network

Abstract

Systems, methods, and devices for power-efficient discovery of infrastructure services on a network are disclosed. In one aspect, a method for using advertising windows to transmit service information on a network is disclosed. The method includes transmitting timing information regarding an advertising window during which information on services offered by one or more nodes on the network will be advertised. The method further includes during the advertising window, transmitting information on services offered by one or more nodes on the network.

What is claimed is: 
     
         1 . A method for using advertising windows to transmit service information on a network, the method comprising:
 transmitting timing information regarding an advertising window during which information on services offered by one or more nodes on the network will be advertised; and   during the advertising window, transmitting information on services offered by one or more nodes on the network.   
     
     
         2 . The method of  claim 1 , further comprising receiving a query from a wireless device for one or more services offered by one or more nodes on the network, and wherein transmitting information comprises transmitting information on the one or more services. 
     
     
         3 . The method of  claim 1 , further comprising receiving from a wireless device a query for one or more services offered by one or more nodes on the network, and wherein transmitting timing information comprises transmitting timing information to the wireless device regarding an advertising window comprising a response to the query. 
     
     
         4 . The method of  claim 1 , further comprising during the advertising window, allowing other wireless devices to transmit information regarding services offered by the other wireless devices. 
     
     
         5 . The method of  claim 1 , further comprising constructing a beacon or a probe response frame which contains timing information. 
     
     
         6 . The method of  claim 1 , further comprising transmitting a minimum time to respond to a query. 
     
     
         7 . The method of  claim 1 , further comprising:
 receiving a query for one or more services offered on the network; and   during the advertising window, re-transmitting the query for one or more services offered on the network.   
     
     
         8 . A wireless communication device, the device comprising:
 a transmitter, the transmitter configured to:
 transmit timing information regarding an advertising window during which information on services offered by one or more nodes on the network will be advertised; and 
 during the advertising window, transmit information on services offered by one or more nodes on the network. 
   
     
     
         9 . The device of  claim 8 , further comprising a receiver configured to receive a query from a wireless device for one or more services offered by one or more nodes on the network, and wherein transmitting information comprises transmitting information on the one or more services. 
     
     
         10 . The device of  claim 8 , further comprising a receiver configured to receive a query from a wireless device for one or more services offered by one or more nodes on the network, and wherein transmitting timing information comprises transmitting timing information to the wireless device regarding an advertising window comprising a response to the query. 
     
     
         11 . The device of  claim 8 , the transmitter further configured to, during the advertising window, allow other wireless devices to transmit information regarding services offered by the other wireless devices. 
     
     
         12 . The device of  claim 8 , the transmitter further configured to construct a beacon or a probe response frame which contains timing information. 
     
     
         13 . The device of  claim 8 , further comprising transmitting a minimum time to respond to a query. 
     
     
         14 . The device of  claim 8 , the wireless communication device further configured to act as an access point. 
     
     
         15 . The device of  claim 8 , further comprising:
 a receiver configured to receive a query for one or more services offered on the network; and   the transmitter further configured to:
 during the advertising window, re-transmit the query for one or more services offered on the network.
