摘要： A system and method schedules downloading of content files from a content server to a client through a cache server. A user can request a content file for future delivery at a certain service time at a certain location such as a hotspot. A cache server receives these requests and sorts them in an order which depends on the relative service times, and eliminates redundancies by only downloading content files not already stored in the cache server. A scheduling algorithm minimizes the instances of tardiness under the constraint of cache storage capacity.

摘要： Remote site downloading of content to a hotspot occurs by way of a cache server, which, when networked the hotspot, processes download, order proxies received from remote content provider servers or content user mobile devices. The cache server stores content files downloaded over the Internet from the content provider servers according to the proxies, and delivers content files to the appropriate mobile devices when they sign in at the hotspot. For example, a set top box at a hotspot can receive an instant message which includes a data set, including cookies, from a personal data assistant. There after, the set top box can download a movie from a movie vendor web site which has been previously ordered and paid for by a user using the personal data assistant over a cellular network, and then wirelessly transmit the movie to the personal data assistant using Wi-Fi protocol when it arrives at the hotspot and is authenticated.

摘要： The downloading of content to a requesting client (A1, A2 and A3) through content distribution network consisting of edge servers occurs upon receiving a content request, a content server responses with a request-routing message that includes source data identifying the content and path data identifying a path through the network to a source of such content. Having the path information in request-routing message enables a requesting client to make the request to a particular edge server, which in turn can register the downloading request and access the content from an appropriate location, thereby obviating the frequent communication between the content server and edge servers on the path.

摘要： A remote site downloading system is disclosed in which a local computer establishes a session with a content server, and a content file and geographic destination drive are selected. The local computer is typically on a first access network and the user wishes to have the file downloaded to a geographic drive, i.e., a remote site computer whose location and other properties are mapped in a mapping file on the local computer. The geographic drive is usually on a different access network in a dynamic location such as a hotspot or a fixed location such as broadband cable or DSL. The local computer is specially programmed to allow selection of the geographic target drive, pack information comprising cookies and a URL, and sends it to the remote geographic drive computer, where it may act as a proxy to cause downloading from the content server to the geographic drive on the remote site computer.

摘要： A method of Authentication Authorization and Accounting (AAA) in an interworking between first and second networks that do not belong in the same administrative domain, using certificate based transactions. In the method according to the invention, the second network sends a public key to the first network, and a certificate to a mobile device. The certificate includes information regarding the subscription level of the mobile device and is signed with a private key of the second network. Upon detection of the first network the mobile device transmits the certificate and the first network authenticates the certificate using the public and private keys of the second network, and authorizes access to the network in response. The first network then sends a session key encrypted with a public key of the mobile device. The mobile device decrypts the session key with a private key and access the first network using the session key. In this manner, interworking is implemented without requiring the deployment of a special interworking function to bridge between the two different types of networks.
