    摘要: A method and apparatus for electing broadcast relay nodes (520B, H, M) in an ad hoc network (500). Each node (520A-520O) generates an attribute message including associated parameters. Each node (520A-520O) generates a weighted value (WV) based on the parameters. The WV can be included in the attribute message for that node, can provide a metric for ranking that node to be nominated to be a broadcast relay node, can alternatively provide a probability measure for that node to probabilistically elect itself as a broadcast relay node. The broadcast manager node (520C) receives the attribute messages and elects at least one nominated node as a broadcast relay node (520B, H, M) based on the attribute messages. Each node (520A-520O) can also initiate election of an intermediate broadcast relay node if that node fails to receive a test message within a predetermined time.

    摘要: A wide area network assisted multimedia content delivery system (200) includes a first wide area network handset (205) and a second wide area network handset (207) having one or more transceivers (208) for exchanging information over the wide band network as well as multimedia information via an ad hoc communication. A wide area base unit (201) is used for communicating with the first wide area network handset (205) and second wide area network handset (207) where a content distribution broker (203) associated with the wide area base unit (201) is used for brokering multimedia content (audio, video and text data) between the first wide area network handset (205) and the second wide area network handset (207). The transceiver (208) operates to exchange multimedia content in an ad hoc communication directly between the first wide area network handset (205) and second wide area network handset (207) when within a predetermined proximity.

    摘要: A method of maintaining call quality in a communication system by communicating between a base site (101) and a communication unit (113) on a first channel. The communication unit (113) monitors the downlink communication signal (116) transmitted by the base site (101) and determines a characteristic of the first channel. The communication unit (113) is then handed off to a second channel having a less aggressive reuse pattern, based on the characteristic of the first channel.

    摘要: Some embodiments are directed to a method and apparatus for performing resource negotiation in a station implementing a direct communication link with at least one other station on an Orthogonal Frequency-Division Multiple Access (OFDMA) data channel. The station scans sub-channels on the data channel for base headers included in predefined position in transmissions sent on the sub-channel. The station then decodes a base header in at least one selected sub-channel to obtain parameters of a channel reservation. The obtained parameters are stored in a channel utilization table. The station selects a resource on the data channel in at least one of time or frequency that the station has observed to be free using information from the channel utilization table. The station then begins a resource negotiation process about the selected resource.

    摘要: Disclosed are methods that associate “importance” information with chunks of a media presentation. An end-user device uses this information to intelligently manage resources when downloading or rendering the media presentation. An editor tags a chunk as important based on the contents of the chunk. The importance information includes a recommendation that this chunk be rendered at a higher-than-usual resolution and that the end-user device start downloading this chunk out of order. An advertiser recommends that an advertisement be rendered at a resolution high enough for the end user to view it appropriately. The importance information can include a recommended point at which to display the advertisement (e.g., between scenes in the media presentation). The end-user device can download advertisements before they are needed. Later, when the user requests a media presentation, an already downloaded advertisement is rendered while the initial chunks of the media presentation are downloaded.

    摘要: A method and apparatus for quieting multiple channels on unlicensed spectrum is provided herein. During operation, a cluster head (or centralized controller such as a base station) will listen to determine if channels exist without primary system traffic. A message will then be sent out by the cluster head quieting the channels. All secondary nodes in the cluster will transmit a CTS-to-self if they do not hear any traffic by any primary system node (which may be nodes out of range of the cluster head) on the channels, otherwise they send a NAK on channels not being used by the hidden nodes. If a NAK is received by the cluster head, the process repeats until no NAK has been received. After the primary system is quieted, a poll message is sent by the cluster head to nodes instructing them to send a CTS-to-Self message so that the spectrum is quieted for the period indicated in the message.
