Abstract

Systems and methods share context information on a neighbor aware network. A method for communicating data in a wireless communications network is disclosed. The method includes receiving, by a device, a first message from a station, decoding the message to determine service information, the service information identifying a service provided by the station, generating a second message, wherein the second message is generated to indicate the service provided by the station and service information of the device, and transmitting, by the device, the second message to a remote station.

First claim

What is claimed is:

1. A method for communicating data in a wireless communications network, comprising:
receiving, by a device, a first message from a station;
decoding, at the device, the first message to determine a proxy preference number of the station and to determine service information, the service information identifying a service provided by the station, and the proxy preference number of the station indicating a level of capability or a level of interest the station has in being a proxy station;
comparing the determined proxy preference number of the station with a proxy preference number of the device, the comparison being based at least on the indicated level of capability or the indicated level of interest the station has in being a proxy station; and
based on the comparison:
generating, at the device, a second message, wherein the second message is generated to indicate the service provided by the station and the service information of the device; and
transmitting, by the device, the second message to a remote station, the remote station being different from the station.

2. The method of claim 1 ,
wherein the generating and transmitting of the second message is conditioned on a result of the comparison.

3. The method of claim 1 , further comprising:
receiving a third message from the remote station; and
decoding the third message to determine an error indicating that the remote station cannot contact the station.

4. The method of claim 1 , further comprising:
transmitting a proxy offer message to the station in response to decoding the service information from the station; and
generating the second message if a proxy accept message is received from the station.

5. The method of claim 1 , further comprising:
receiving a proxy request message from the station;
determining whether to accept the proxy request;
generating a broadcast message indicating the device is configured to serve as a proxy station if the proxy request is accepted; and
transmitting the broadcast message to a broadcast address.

6. The method of claim 1 , wherein the service information comprises at least one of an indication of an availability of pressure measurements, an indication of an availability of temperature measurements, an indication of an availability of location measurements, an indication of an availability of ambient sound measurements, an indication of an availability of ambient light measurements, an indication of an availability of humidity measurements, an indication of an availability of emergency alarm sensor measurements, a pressure measurement, a temperature measurement, a location measurement, an ambient sound measurement, an ambient light measurement, a humidity measurement, and an emergency alarm sensor measurement.

7. The method of claim 1 , further comprising:
receiving a station identifier and a wake up schedule from the station;
decoding one or more of a media access control (MAC) address, an application based identifier, an Internet Protocol (IP) address, and a device name from the station identifier;
decoding one or more of a time when the station will be awake to listen for messages from other devices and a channel that the station will use to communicate during the time, from the wake up schedule; and
generating the second message to indicate the wake up schedule.

8. An apparatus for communicating data in a wireless communications network, comprising:
a receiver configured to receive a first message from a station;
a hardware processor configured to:
decode the first message to determine service information, the service information identifying a service provided by the station, and further configured to decode the message to determine a proxy preference number of the station, the proxy preference number of the station indicating a level of capability or a level of interest the station has in being a proxy station;
compare the determined proxy preference number of the station with a proxy preference number of the apparatus, the comparison being based at least on the indicated level of capability or the indicated level of interest the station has in being a proxy station; and
generate a second message to indicate the service provided by the station and the service information of the apparatus, the generating being based on the comparison; and

a transmitter configured to transmit the second message to a remote station, the transmitting being based on the comparison.

9. The apparatus of claim 8 ,
wherein the hardware processor is further configured to condition the generation and transmission of the second message on a result of the comparison.

10. The apparatus of claim 8 , wherein the transmitter is further configured to transmit a proxy offer message to the station in response to decoding the service information from the station, and wherein the hardware processor is further configured to generate the second message if the receiver receives a proxy accept message from the station.

11. The apparatus of claim 8 ,
wherein the receiver is configured to receive a proxy request message from the station,
wherein the hardware processor is configured to determine whether to accept the proxy request,
wherein the hardware processor is further configured to, based on the determination, generate a broadcast message indicating the apparatus is configured to serve as a proxy station, and
the transmitter is configured to transmit the broadcast message to a broadcast address.

12. The apparatus of claim 11 , wherein the hardware processor is further configured to generate the broadcast message to indicate an incentive to become a proxy and to indicate a time when proxy service is available.

13. The apparatus of claim 8 , wherein the service information comprises at least one of an indication of an availability of pressure measurements, an indication of an availability of temperature measurements, an indication of an availability of location measurements, an indication of an availability of ambient sound measurements, an indication of an availability of ambient light measurements, an indication of an availability of humidity measurements, an indication of an availability of emergency alarm sensor measurements, a pressure measurement, a temperature measurement, a location measurement, an ambient sound measurement, an ambient light measurement, a humidity measurement, and an emergency alarm sensor measurement.

14. The apparatus of claim 8 ,
wherein the receiver is further configured to receive a station identifier and a wake up schedule from the station,
wherein the station identifier comprises at least one of a media access control (MAC) address, an application based identifier, an Internet Protocol (IP) address, and a device name,
wherein the wake up schedule comprises a time when the station will be awake to listen for messages from other devices and a channel that the station will use to communicate during the time,
and the hardware processor is further configured to generate the second message to indicate the wake up schedule.

15. A method for communicating data in a wireless communications network, comprising:
receiving, by a device, data from a proxy station, the data including a proxy preference number of the proxy station, the proxy preference number of the proxy station indicating a level of capability or a level of interest the proxy station has in being a selected proxy station;
comparing, at the device, the data received from the proxy station with data associated with the device, the comparison being based at least on the indicated level of capability or the in
