IPC: H04B7/185
Filed: 2003-08-15
Abstract: Selon la présente invention, la capacité d'un système de communications sans fil terrestre utilisant une bande de fréquence terrestre pour des communications avec des terminaux sans fil est étendue au moyen d'une bande de fréquence satellite pour la réception terrestre de communications terrestres émanant de terminaux sans fil. Comme les terminaux sans fil sont configurés pour transmettre des communications à un composant basé dans l'espace, tel qu'un satellite, via une bande de fréquence satellite, ces transmissions peuvent également être obtenues (reçues) au niveau terrestre. De ce fait, des stations de base terrestres peuvent être équipées de récepteurs de bande de fréquence satellite qui peuvent recevoir des communications provenant de terminaux sans fil par le biais d'une bande de fréquence satellite. L'utilisation du récepteur de bande de fréquence satellite dans une station de base terrestre permet de fournir une capacité et/ou une qualité de service supplémentaires au système de communications terrestre et/ou satellite.

IPC: H04L29/12
Filed: 2004-01-14
Abstract: A method, apparatus, and program for requesting a page from a server (302) in a networked computer system. The page is requested, using a domain name, a first time from a client application (300) in the computer system in which the page is requested. An Internet Protocol address for the domain name is looked up on a remote domain name server (304) and used to request the page. The address is stored locally in an address translation database (304), accessible only by the client application, associated with the page domain name.  Subsequent page requests may be processed using this database, which is referenced in response to a page request to determine whether an address is present for the page. The page is requested using an address returned from the database if it is present. Otherwise, the remote domain name server is queried to determine the address of the selected page.
