Abstract
(EN) Systems and methods for screening access to a Wireless Access Protocol (WAP) server provide the ability to screen messages received from terminals which are not permitted access to the WAP server before the messages are actually input to the WAP server. A security manager configures the server to accept of deny access to the WAP server to terminals by entering the allowed terminal identification numbers to a WAP protocol stack (WPS) which is accessed to determine if terminals requesting access are entered onto a list of terminals allowed access. If access is permitted, the messages are input to the WAP server, but if access is denied, the messages are not permitted access to the WAP server. By screening the messages before they are input to the WAP server, the efficiency of the WAP server is greatly increased since it is not required to operate in any manner on messages which are denied access.
(FR) Systèmes et procédés servant à filtrer l'accès à un serveur de protocole d'accès sans fil (WAP) et permettant de filtrer des messages reçus de terminaux ne possédant pas d'autorisation d'accès au serveur WAP avant l'entrée réelle de ces messages dans ce serveur WAP. Un gestionnaire de sécurité effectue la configuration du serveur afin d'accepter ou refuser l'accès à ce serveur WAP aux terminaux au moyen de l'entrée de numéros d'identification de terminal autorisé dans une pile de protocoles WAP (WPS) à laquelle on accède afin de déterminer si les terminaux demandant l'accès sont enregistrés sur une liste d'accès autorisés. Si l'accès est autorisé, les messages sont entrés dans le serveur WAP, mais si l'accès est refusé, ces messages ne sont pas autorisés à accéder au serveur WAP. Le filtrage des messages, préalablement à leur entrée dans le serveur WAP, permet d'améliorer considérablement l'efficacité de ce serveur, étant donné qu'il n'est pas nécessaire de traiter les messages dont l'accès est refusé.
