摘要： Disclosed is a method for requesting for location information of resources on a P2P network, user node and server for the same, which allow a user to get network resources quickly. The popular files and the unpopular files are managed separately. The metadata of popular files are stored a plurality of SN based on respective areas, while the metadata of the unpopular files are stored and queried in a centralized manner. A function of redirecting a request message is added into the SN so as to inform the user the existence of a SN-R. Meanwhile, in order to improve query efficiency and avoid repeatedly redirecting of the message, a server routing table is provided for the user node which can indicate which files need to be download and which server should be requested to provide the files. Due to the popular filed and the unpopular filed are stored separately and all of unpopular files are stored in a centralized manner, the user can get unpopular files when the user request for the unpopular files in a P2P network.

摘要： Methods, devices and system for access point facilitated fast handoff are provided. Each access point (AP) in a wireless local area network is provided with a primary interface and a secondary interface wherein the primary interface performs normal communication with user terminals and broadcasts standard beacon frames on its working channel, and the secondary interface broadcasts extended beacon frames on working channels of neighbor APs sequentially. The extended beacon frame includes at least information of BSSID, SSID, working channel and the like of the primary interface of the corresponding AP. The user terminal may receive the standard beacons from the serving AP it is communicating with and the extended beacons from the neighbor APs, and according to the two kinds of beacons, the terminal may calculate the signal quality with the primary interface of the serving AP and the signal qualities with the neighbor APs at the current position. By an algorithm of comparing the signal qualities of the best neighbor AP and the serving AP, the terminal may accurately and quickly determine whether to perform handoff with minimized cost.

摘要： Methods and device for user terminal based fast handoff are provided. User terminal builds a neighbor group list in which possible neighbor access points (APs) are divided into one or more groups. When a handoff needs to be prepared, the user terminal performs intermittently multiple pre-break probing subphases according to the neighbor group list while not breaking connection with a current serving AP. In each PBP subphase, signal qualities of neighbor APs in one group are probed in a manner of active probing. The user terminal selectively performs handoff according to the probed signal qualities of the neighbor APs. The user terminal may build the neighbor group list based on information of neighbor APs derived through overlapped channel scanning or information of neighbor APs received from the serving AP. The neighbor APs belonging to the same group work on the same channel and in each PBP subphase, a group of neighbor APs may be probed by using unicast probe request.

摘要： Input streams for acoustic echo cancellation are associated with timestamps using reference times from a common clock. A render delay occurs between when an inbound signal is written to a buffer and when it is retrieved for rendering. A capture delay occurs between when a capture signal is written to a buffer and when it is retrieved for transmission. Both the render delay and the capture delay are variable and independent of one another. A render timestamp applies the render delay as an offset to a reference time at which the inbound signal is written to the buffer for rendering. A capture timestamp applies the capture delay as an offset to a reference time at which when the capture signal is retrieved for transmission. Applying the delay times as offsets to the reference times from the common clock facilitates synchronizing the streams for echo cancellation.
