    摘要： Techniques disclosed herein include systems and methods for providing active mobility of Wi-Fi enabled devices within a given wireless local area network (WLAN). In general, techniques include dynamically commanding Wi-Fi enabled devices to disconnect from a corresponding access point in response to meeting predetermined conditions. A forced disconnect can be based on various criteria such as low-power or lost packet thresholds triggering the forced disconnect. Such techniques cause a Wi-Fi enabled device to disconnect from one access point and connect to another access point before a connection quality deteriorates to a point that causes noticeable interruptions in connectivity or a generally poor experience, thereby enabling a smooth transition among access points.

    摘要： A wireless access point employs a wireless configuration database for retrieving a stored wireless profile corresponding to a subscriber device from a remote location that enables the user to establish an Internet connection using their subscriber device with the same network identifiers and settings employed from the home wireless profile. The network identifier is typically an SSID (Service Set Identification), and labels the wireless configuration using a mnemonic name familiar to the user. The wireless configuration also denotes authentication and security (passphrase) tokens required for access, and would therefore enable the user to sign on at the remote wireless access point using the passphrase already known from their home WiFi arrangement. Subsequent attempts automatically establishing a connection to the subscriber device upon detection and authentication using the retrieved wireless profile without broadcasting an open SSID receivable by other wireless devices within range.

    摘要： Methods and apparatus for supporting content delivery service are described. In accordance with the invention content can be supplied to temporary storage of a regional or local server used to supply the content to a customer's premises when the requested content is not already available in the regional or local server. A content server hierarchy may be implemented with servers higher up in the hierarchy including more content, e.g., titles, than the number of titles stored in the lower level servers. By storing less frequently accessed content in servers higher in the hierarchy and frequently requested titles lower in the hierarchy, a vast number of titles can be supported without overburdening the storage available at local and regional servers. In addition, a national or other server high in the hierarchy can be used to store, move, and distribute local or other content as part of an on demand service.

    摘要： Systems and methods for Wi-Fi roaming. A gateway supports both a local access point (AP) and a virtual AP. The local AP is accessible only to an "owner" of the gateway. The virtual AP (VAP) is accessible to devices associated with the owner of the gateway and to roaming Wi-Fi devices. A datastore conveys information about the roaming Wi-Fi devices to the VAP to permit them to access the VAP without the need for manual configuration of the VAP. A roaming Wi-Fi device may communicate with a gateway via a tunnel to maintain session connectivity during roaming. A session may be initiated on one network, such as a Wi-Fi network or a cellular network, handed off to another network, such as a cellular network or a Wi-Fi network, and then returned to network on which the session was initiated.

    摘要： A technique is provided for securely transferring programming content from a first device in a first layer, e.g., a trusted domain, to a second device in a second layer, e.g., outside the trusted domain. When a user requests that the first device transfer protected content to the second device, the first device needs to authenticate the second device. After the second device is authenticated, the first device may transfer to the second device the protected content, together with a rights file associated therewith. The rights file specifies the rights of the second device to use the protected content, according to its security level indicative of its security. These rights may concern, e.g., the number of times that the second device may subsequently transfer the protected content to other devices, the time period within which the second device may play the protected content, etc.; The higher the security level of the second device is, the more rights accorded thereto. Indeed, the second device may need to meet a minimum security level requirement in order for it to receive or keep the protected content.
