    摘要： A presence information system allows access to presence information of a publisher to be controlled and enforced by the publisher on a peer-to-peer basis, rather than by a presence server. A subscriber sends to the publisher on a peer-to-peer basis a request to subscribe to the presence information of the publisher. When the publisher receives the request to subscribe to its presence information, the presence information system of the publisher can allow or deny the request based on access rights associated with the subscriber. If the request is allowed, then the publisher notifies the subscriber of its current presence state and its new presence state when it changes. The presence states may be defined at various levels of detail in a presence model.

    摘要翻译： 呈现信息系统允许对发布者的存在信息进行访问，以由发布者在对等的基础上而不是由呈现服务器来控制和强制执行。 用户在点对点的基础上向发布者发送订阅发布者的存在信息的请求。 当发布者接收到订阅其存在信息的请求时，发布者的呈现信息系统可以基于与订户相关联的访问权限允许或拒绝该请求。 如果允许请求，则发布者在更改时通知用户其当前存在状态及其新存在状态。 存在状态可以在存在模型中以各种细节级别来定义。

    摘要： A wireless device and method provides for adding nodes to a wireless mesh network by adjusting an antenna sensitivity pattern of one or more nodes in the wireless mesh network to exhibit spatial selectivity. The method transmits a query, and if a response is received within a predetermined time period, the wireless device receives the response and adds the responding wireless device to the mesh network. The wireless device can adjust the transmission pattern to enable the antenna sensitivity pattern to cover a predetermined spatial area, and the predetermined time period can be fixed. The wireless devices can adjust the antenna sensitivity pattern in a coordinated manner. A method for supporting data connections between three or more wireless devices includes adjusting the sensitivity pattern of an antenna on a first wireless device, communicating with a second wireless device, and further adjusting the sensitivity pattern of the antenna for more wireless devices.

    摘要： An architecture for an extensible real-time collaboration system providing a unified interface is provided. The architecture presents a unified application program interface for writing application programs that use communications protocols. The architecture has presence and activity objects, multiple endpoint objects, and a collaboration service object. These objects may use various communications protocols, such as Session Initiation Protocol or Real-Time Transport Protocol, to send and receive messages. The presence and activities objects, multiple endpoint objects, and collaboration service object may each have one or more APIs that an application developer can use to access or provide various functionalities. These objects map the API to the underlying implementation provided by other objects.

    摘要： A mobile computer establishes a wireless communication session with a wireless access point of a computer network. The location of each wireless access point is known and obtainable either from a database on the network or from the access points themselves. The strengths of wireless signals passing between the mobile computer and multiple wireless access points of the network, including the access point with which the mobile computer has established the session are measured at multiple time intervals. The measurements may be taken at the mobile computer itself or at the wireless access points. The measured strength values are then weighted according to such factors as whether the mobile computer has already established a communication session with the access point from which the sample was taken, and how old the sample is. For each location, the weighted strength values obtained for access points in that location are summed. The location having the highest sum is deemed to be the location of the mobile computer.

    摘要： A primary call admission controller (CAC) system receives a request from a client to allocate a network resource such as a network bandwidth. The primary CAC system may determine subordinate CAC to delegate the allocation and transfer the request to the subordinate CAC. Subsequently, the subordinate CAC analyzes the communication session attributes to determine an available network resource for the communication session. Upon a positive determination, the subordinate CAC allocates the network resource and signals the allocation up the network chain to the primary CAC and the client.

    摘要： A method and system for reducing the number of ports allocated by a relay server is provided. A connection system uses a bidirectional technique to establish a connection via the relay server between two endpoints (e.g., client computers) that can be used bidirectionally to send a stream from a first endpoint to a second endpoint and a stream from the second endpoint to the first endpoint. The connection system may also use a stream multiplexing technique to further reduce the number of ports allocated by a relay server by multiplexing multiple streams onto a single connection. The connection system may also use an endpoint multiplexing technique to reduce the number of ports allocated by a relay server by multiplexing streams from different endpoints through a single connection via the relay server.
