摘要： The present invention provides a method and system for providing quality-of-service to VoIP over a wireless local access network by providing periodic, contention-free access to a wireless link for voice packets. This is achieved by coupling Session Initiation Protocol (“SIP”) signaling for call setup with the Point Coordination Function mode of operation of the 802.11 medium access control. The result is that VoIP call signaling via SIP is tied with availability of periodic time-slots on the wireless medium. The periodic time-slots are used to guarantee contention-free access to the wireless link for voice packets. Accordingly, the present invention, in effect, merges two networking technologies: SIP-based VoIP and 802.11-based wireless LANs.
摘要翻译：本发明提供一种通过向语音分组的无线链路提供周期性的无争用访问来提供通过无线本地接入网络向VoIP提供服务质量的方法和系统。这通过将会话发起协议（“SIP”）信令与用于802.11媒体访问控制的点协调功能模式的呼叫建立相结合来实现。结果是通过SIP的VoIP呼叫信令与无线介质上的周期性时隙的可用性相关联。周期性时隙用于保证无争用地访问无线链路的语音数据包。因此，本发明实际上合并了两种联网技术：基于SIP的VoIP和基于802.11的无线LAN。

摘要： Systems and associated methods for providing scalable presence subscriptions in federated presence environments are described. Embodiments provide for intelligent addition of subscriptions to a presence system. Embodiments identify if a virtualized presentity (corresponding to a new query) can be composed from existing virtualized presentities, and if so, corresponding query processing cells (QPCs) (servicing existing queries) are reused to retrieve the presence information (partially or fully) for the new incoming query. Embodiments organize the existing QPCs into a hierarchy such that a QPC/virtual presentity at a higher layer fetches presence information of all or some presentities from QPCs/virtual presentities at lower layer(s) to service the new query.

摘要： The present invention is directed to a session initiation protocol (SIP) infrastructure containing various user devices and the use of this infrastructure to conduct media exchange sessions among the various user devices. Included in the user devices are wearable devices, for example pendants and wrist watches, that provide readily available and accessible devices for use in controlling the media exchange sessions. SIP permits the separation of the control aspects of a session from the actual media exchange aspects to facilitate the use of wearable devices having limited processing resources as control devices. The actual media exchange is directed to user devices suitable for sending, receiving and displaying the exchanged media.

摘要： A method for operating a server having a maximum capacity for servicing requests comprises the following steps: receiving a plurality of requests; classifying each request according to a value; determining a priority for handling the request according to the value, such that requests with higher values are assigned higher priorities; placing each request in one of multiple queues according to its priority value; and dropping the requests with the lowest priority when the plurality of requests are received at a rate that exceeds the maximum capacity. The server operates according to a session initiation protocol.Classifying each request comprises running a classification algorithm. The classification algorithm comprising steps of: receiving a rule set, each rule comprising headers and conditions; creating a condition table by taking a union of all conditions in the rules; creating a header table by extracting a common set of headers from the condition table; extracting the relevant headers from the header table; determining a matching rule; creating a bit vector table; selecting the matching rule according to data in the bit vector table; and applying the rule to place the message in the appropriate queue.
