Abstract: Presented is a method, system and computer readable product to search a task-based web interaction. A task-based web interaction search query is provided to a search engine. The search results are classified into a set of information parameters. The information parameters are compared against a repository containing multiple sets of information parameters. Upon identification of a corresponding set of information parameters, a task-based web interaction associated with the identified set of information parameters is presented.

Abstract: A method, system and apparatus for synchronizing multiple streams of a communication session between a wireless station device (STA) and one or more communication devices via a wireless access point (AP) of a wireless local area network (WLAN), includes a host processor determining a synchronization period in accordance with packetization periods of each of the multiple streams, switching the STA to a doze mode until expiration of the synchronization period, buffering packets generated during the synchronization period, and switching the STA from the doze mode to an active mode upon expiration of the synchronization period and decompressing or transmitting packets generated while the STA is in the active mode.

Abstract: A method for reducing the number of channels that are scanned during a handoff situation for a wireless endpoint station in a wireless local area network (WLAN), such as an IEEE 802.11 network, by tracking past user movements within the WLAN. A suitable sequence of channels to be scanned is generated so that reduce the number of handoffs are reduced and the average time during a handoff is reduced. To reduce handoffs and handoff latencies, the principle of locality (user movement patterns tend to be repetitive) is used. By tracking the past handoffs, future handoffs are predicted.

Abstract: Disclosed above are various embodiments of VoIP communication systems that utilize low cost IP phones that rely on a centralized VoIP controller for much of the processing. Reducing the processing taking place on an IP phone may reduce the number of components that need to be on the IP phone which may result in a less expensive IP phone in terms of both cost and power. When the IP phone is embodied as a WIPP, the reduced processing may also result in more efficient communication between the WIPP and an AP. The increased communication efficiency may result in less power being used by the WIPP and effectively extend the battery life. Since a number of redundant components have been centralized, the VoIP system as a whole may be less costly. Also, centralized control may provide greater functionality and versatility in the setup and configuration of a VoIP communication system.
