Various embodiments for service constraint advertisement and discovery are provided. Each wireless device in a group of wireless devices can multicast a service advertisement frame to advertise a service provided, a discovery request frame to request for a service, a discovery response frame in response of a discovery request frame if the wireless device can provide the requested service, or a discovery proxy response frame in response of a discovery request frame if another wireless device can provide the requested service. The frames include information related to one or more services and capabilities, availability schedule, frequency band in use, and other information. This allows a new device joining the group to accomplish device discovery and service discovery at the same time. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. |
