Patent number: 8634771Abstract: Wireless devices that support bootstrapping of a peer-to-peer connection. The wireless devices may use an infrastructure mode connection to exchange security information, such as a PIN, used in establishing the peer-to-peer connection. This security information may be encrypted in accordance with a security protocol used by the access point and then may be applied in a security protocol used to establish a peer-to-peer connection. Such a bootstrapping capability supports operating scenarios in which devices that are communicating over an infrastructure network encounter an operation that requires transfer of large amounts of data and automatically transition to a peer-to-peer connection that provides better performance. With these techniques, a computing device may automatically connect to a display device and stream audio/video data to the display.Type: GrantFiled: June 15, 2011Date of Patent: January 21, 2014Assignee: Microsoft CorporationInventors: Amer A.

Publication number: 20120290730Abstract: A system in which wireless devices form a group in accordance with a peer-to-peer protocol and, at a later time, a device may send an invitation request to trigger the devices tore-form the peer-to-peer group. The invitation request may contain an identifier that is associated with a set of a plurality of devices. Those devices may be related such that they perform a function for which a user would want to use those devices together. The group of devices, for example, may be multimedia devices that receive and present streaming multimedia content or may be human interface devices that collectively act as an interface for a work station incorporating a wireless computing device operated by a user. Requesting that remote devices concurrently re-form a group reduces the time and spectral congestion associated with re-forming the group, particularly when the remote devices may periodically enter a low power state.Type: ApplicationFiled: May 12, 2011Publication date: November 15, 2012Applicant: Microsoft CorporationInventors: Mitesh K.

Publication number: 20120239755Abstract: A computing device that forms a group in accordance with a peer-to-peer protocol in which a device may be identified based on a credential of a user. The credential may be used to determine a unique identifier for the user such that the same identifier is used on any device operated by the same user. Such an identifier may be used in connection with a peer-to-peer protocol that supports persistent peer-to-peer groups. As a result, the unique identifier for the user may be retained by remote devices that have paired with any device operated by a particular user such that those remote devices may automatically establish a connection with any other device operated by the same user that similarly uses the same unique identifier for the user.Type: ApplicationFiled: March 14, 2011Publication date: September 20, 2012Applicant: Microsoft CorporationInventors: Henrique Filgueiras, Mukund Sankaranarayan, Amer A.

Publication number: 20120233266Abstract: A computing device that selectively renegotiates roles of devices in an existing peer-to-peer group. As the group is formed, the device may negotiate with other devices to select a device to control the group. During operation of the group, a device in the group may initiate a renegotiation that may lead to the selection of an alternative device to control the group. Renegotiation may be triggered by a message containing an information element signifying a request for renegotiation. Such a message may be sent either by the controlling device or other device in the group, and may be sent based on a state of the device. The state may relate to a source of power to the device such that a client that is connected to a source of power or a controlling device that is running low on battery power may request a renegotiation.Type: ApplicationFiled: March 11, 2011Publication date: September 13, 2012Applicant: Microsoft CorporationInventors: Amer A.

Publication number: 20120158839Abstract: An architecture for a computing device to enable the computing device to support peer-to-peer communications using a wireless radio also configured for infrastructure-based communication. The architecture includes a driver for the wireless radio that supports ports for communication in accordance with the peer-to-peer protocol. A port may act as a control port through which action frames that control the formation of a peer-to-peer group may be sent and received. One or more other ports may be used for exchanging data with other devices in the group. Each of these ports may be configured in accordance with its role in the group, such that each port may be configured for operation as a group owner or a client. Additionally, after establishing a group, the control port may be used as a side channel for controlling a device in a group associated with another port.Type: ApplicationFiled: December 16, 2010Publication date: June 21, 2012Applicant: Microsoft CorporationInventors: AMER A.

Publication number: 20120158981Abstract: A wireless peer-to-peer protocol that supports fast and low power joining to an existing group. The protocol may be an extension of a peer-to-peer protocol that supports a sleep state for a device controlling the group. When a device is seeking to join a group at a time when the controlling device is in a sleep state, another device that has information about the controlling device may provide information to the joining device that may then be used by the joining device to more quickly, and using less power, synchronize with the controlling device. The information may include information about a channel used by the controlling device or about timing of availability of the controlling device. The information may also reveal whether the group provides a service being sought by the joining device or may otherwise influence whether the joining device will attempt to join a group.Type: ApplicationFiled: December 16, 2010Publication date: June 21, 2012Applicant: Microsoft CorporationInventors: MITESH K.

Publication number: 20120155643Abstract: A wireless computing device operating as a controller of a peer-to-peer group configured to generate unique master keys for each device joining the group. The wireless computing device may use the unique master keys to selectively remove remote devices from the group such that the remote device cannot later rejoin the group. Other remote devices, each possessing a master key that remains valid, can disconnect from the group and later reconnect to the group without express user action. To support such behavior, the wireless device may provide a user interface through which a user may manage connected remote devices by providing commands to selectively disconnect or remove remote devices from the group.Type: ApplicationFiled: December 16, 2010Publication date: June 21, 2012Applicant: Microsoft CorporationInventors: Amer A.
