    摘要： The present invention provides methods and devices using location detection to enable MMMDs to activate and tune to appropriate radios and networks. Some preferred embodiments use radio frequency identification (“RFID”)—based location detection. Preferably, the location detection occurs at or near wireless domain boundaries. Some implementations employ proximity/boundary detection to enhance handoff triggers, which initiate handoff mechanisms between different networks, as an MMMD moves between wireless networks, via a wireless domain portal. Some implementations involve methods and devices for device validation and authorization. An MMMD is provided with local wireless network awareness, which may be used by the MMMD to have the appropriate radio turned on and properly tuned. Accordingly, the methods and devices of the present invention achieve power savings and improved handoff across networks.

    摘要： Gathering location information from a first wireless network to determine whether to anchor a communication session in a second wireless network, a mobile node capable of communicating with both the first wireless network and the second wireless network, includes receiving location information from the first wireless network as the mobile node moves through one or more service areas of the first wireless network. It is determined whether a triggering event occurs. If the triggering event occurs, the location information is stored to determine whether to anchor a session in the second wireless network.

    摘要： Anchoring a communication session for a target mobile phone includes identifying a current access node operable to provide the target mobile phone access to a first network of a first network type. Potential access nodes operable to provide a mobile phone access to a second network of a second network type are identified. Whether the communication session can be handed off to a potential access node of the one or more potential access nodes is established. Anchoring of the communication session is initiated in the second network only if the communication session can be handed off to a potential access node of the one or more potential access nodes.

    摘要： Devices and methods are provided for minimizing the startup delay of streaming media transmitted through networks. A server maintains a portion of the media stream stored in an initial burst transmit buffer. At startup, the stored portion is transmitted at a rate higher than the fixed frame rate, exploiting the full available bandwidth. The initial burst transmission fills up the de-jitter receive buffer at the receiving end faster, thereby shortening the startup delay. Then transmission is switched to the regular rate, from the regular buffer. A variable bit rate transcoder is optionally used for the data of the initial transmission. The transcoder diminishes the size of these frames, so they can be transmitted faster. This shortens the start up delay even more. A receiver has a buffer with a fill level started at a value lower than a final value. This triggers the beginning of play out faster, further shortening the delay time. The fill level of the de-jitter receive buffer is then gradually increased to a desired final value.
