Peer-to-peer pre-association discovery operations

摘要

A method for discovering P2P service capabilities of peer devices in a Wi-Fi network is disclosed. A client device scans one or more channels of the P2P network to discover peer devices, and receives one or more data frames from a set of peer devices. Each of the data frames includes management information to enable the client device to establish a connection with a corresponding peer device. Each data frame further includes a first set of service information, which includes data indicating whether the corresponding peer device is configured to provide a P2P service. The client device then selectively establishes a P2P connection with a peer device from the set based, at least in part, on the first set of service information.

主权项

1. A method of operating a client device in a peer-to-peer (P2P) network, the method comprising:
during a device discovery phase,
scanning one or more channels of the P2P network to discover a presence of one or more peer devices by broadcasting a probe request to the peer devices, the probe request including a number of first hash values indicating a number of P2P services provided by the client device; andreceiving a first frame from each of a number of the peer devices, wherein each first frame includes (i) management information to establish a P2P connection with a corresponding peer device and (ii) service information indicating a number of P2P services supported by the corresponding peer device; and during a service discovery phase, sending a service discovery request to a selected peer device based, at least in part, on the service information, wherein the service discovery request is to request one or more specific P2P services.
