摘要:
A user device within a communications architecture, the user device comprising: an object management entity configured to determine at least one object for a shared scene, the object associated with at least one changeable attribute; the object management entity further configured to determine a change in at least one of the at least one changeable attribute associated with the object; a message entity configured to generate for the at least one object an object attribute update message; a message delivery entity configured to control the output of the object attribute update message such that for a determined period the number of messages output is less than a send path rate number.

A wireless mesh network enables multiple devices near each other to transmit simultaneously, thus allowing increased network bandwidth. Prior to transmitting, a device may determine various parameters of the wireless medium on which it desires to transmit. For example, the device may determine whether the intended recipient device is close enough, and verify that any other transmitting and receiving devices are far enough away. If these or any other suitable criteria are met, the device can transmit simultaneously with other devices in the vicinity.

A network enabled computer receives connection profile information in a generic form and creates one or more native mode profiles to establish connections. By accepting profile information in a generic form, profile information can be readily provided from one or more ways, including from a policy server, through a user interface or from a third party application. The profile information can be provided with an order of precedence so that profile information from different sources may be combined appropriately. Additionally, the profile information may be provided in an extensible format to allow profile information to be distributed to multiple computers, even if some have different hardware or software configurations and are not programmed to recognize extensions of the profile information.

A system and method for carrying out network and interface selections across multiple media is disclosed. The disclosed system facilitates automated network interface configuration decision-making that spans a set of networks supporting communications via differing media. A set of media specific modules associated with differing communications media acquire network interface status/capabilities information. A rules engine thereafter applies a designated network selection rule(s) to the acquired network interface status/capabilities information, and any other appropriate parameters attributable to either an interface or network, to select one or more networks and interfaces with which to establish/maintain a connection.

A wireless device that desires to be connected to a wireless network broadcasts itself and its capabilities to a network using an information element. The information element is provided with frames, such as management frames, in a channel that is not protected or encrypted. The information element is forwarded to one or more potential registrar devices. One of the registrar devices then provides configuration information to the enrollee, for example as a registrar information element. The configuration information may be passed out of band or in band, and may be passed using cryptography, which may involve public key cryptography, encryption with a PIN, or some other type of secure exchange.

A mechanism is provided to extend the range of wireless devices beyond the range limit that results from timing restrictions imposed by the IEEE 802.11 standard. The mechanism, which operates at the upper level of the 802.11 MAC, determines whether the wireless devices are far apart or not far apart. When the wireless devices are determined to be far apart, the standard retransmission protocol at the lower level of the 802.11 MAC is disabled and a custom ACK packet is utilized. Delivery of a transmitted packet is confirmed if the custom ACK packet is received within a maximum delay period that takes into account the longer propagation delay between wireless devices that are far apart.

It is determined whether a mobile user device is within transmission range of one or hidden networks. A list of known networks may be accessed, the list including broadcast and hidden networks. For the hidden networks, the network connection component may instruct a network interface to actively probe for the hidden networks. If the response is received for a communication corresponding to a particular network, then it may be considered that the mobile user interface is within transmission range of the hidden network. If auto-connection logic is activated, a preference order may be applied to select which of the detected broadcasts and/or hidden networks to connect. A user interface displays broadcast and hidden networks determined to be within transmission range of the mobile user device. The user device also displays hidden networks for which it has not yet been attempted to determine whether the hidden networks are in range.

A wireless diagnostics framework that is non-intrusive and stays out of the way of a user is presented. In the case of a failure, prescriptive guidance is provided and/or the framework possibly automatically fixes the problem. The framework includes a wireless diagnostics module that interacts with the operating system's diagnostics framework, helper classes, and wireless components to collect and log wireless diagnostic events and notifications, and issues queries and requests for active diagnostics. The helper classes perform diagnosis and troubleshooting fore their expertise areas based on the information provided by the wireless diagnostics module. The wireless diagnostics module includes an application program interface for communicating with helper classes, an event listener module that provides an event tracing application program interface to in-process modules, an active diagnostics module that issue active packet test requests to a media specific module, and query modules that issue information query requests to media specific modules.

A user device within a communication architecture, the user device comprising: an image capture device configured to determine image data for the creation of a video channel defining the shared scene; an intrinsic/extrinsic data determiner configured to determine intrinsic/extrinsic capture device data associated with the image capture device; and a video encoder configured to encode the image data and intrinsic/extrinsic capture device data within the video channel.
