Patent

CA 2648122

Methods and apparatus for communicating between an access terminal (AT) and a device serving the AT by way of an Access Point (AP) are described. In accordance with one feature serving devices may be assigned specific addresses which are interpreted based on the source of the communication, e.g., MAC packet, in which the address is used. Such addresses may be interpreted as being of a different type than other addresses which can be interpreted and/or used without taking into account the identity of the sender. In some embodiments Session Controllers and/or Internet Attachment Points (IAPs) are identified with such addresses. The address value is the same for one or more ATs but is interpreted at an AP receiving such the IAP address based on information corresponding to the AT which sent the packet including the IAP or Session Controller address.

L'invention concerne des procédés et un appareil pour communiquer entre un terminal d'accès (AT) et un dispositif servant l'AT au moyen d'un Point d'Accès (AP). Selon une caractéristique, des dispositifs serveurs peuvent se voir attribuer des adresses spécifiques interprétées en fonction de la source de la communication, par exemple un paquet MAC, dans laquelle l'adresse est utilisée. De telles adresses peuvent être interprétées comme étant d'un type différent de celui d'autres adresses qui peuvent être interprétées et/ou utilisées sans tenir compte de l'identité de l'expéditeur. Dans certains modes de réalisation, des Contrôleurs de Session et/ou des Points de Rattachement Internet (IAP) sont identifiés par de telles adresses. La valeur d'adresse est identique pour un ou plusieurs AT mais est interprétée au niveau d'un AP recevant une telle adresse IAP à partir des informations correspondant à l'AT qui a envoyé le paquet comprenant l'IAP ou l'adresse du Contrôleur de Session.
