  • Mobile terminals typically do not have an IP address or a URI associated with them. Therefore, HTTP GET request-line as indicated above is not compatible with, for example, mobile terminal 12, when content is desired to be retrieved from mobile terminal 12.
  • HTTP GET request from the mobile communication device 22 may take a form of "http://www.domain-name/identifier" or "http: identifier.domain- name”.
  • the "identifier" portion of the URI pathname reflects the identity of the web server mobile terminal 12 and the "domain-name" portion of the URI pathname reflects the domain name of a gateway 40 in the network.

In other words, normal HTTP traffic may be tunneled between the mobile terminal 12 and the gateway 40.
  • the technology of delivering the data between mobile terminal and gateway can be anything if the terminal and the gateway have a common knowledge of it.) This is possible because the mobile terminal 12 needs to register or inform about itself to " the gateway 40 and set-up said tunneling in order to be available to external devices. In an embodiment, also the HTTP request may go directly to the server, if the gateway is not needed in the system. [0044] However, it may happen that the web server mobile terminal is off-line, no bearer can be implemented and other users cannot reach the server functionality. It has now been found that it might be desirable to provide means for informing other users when the server becomes available again.

Abstract

L'invention concerne un procédé de contrôle d'accès à un serveur d'information. Ce procédé consiste à: recevoir une tentative d'accès à un serveur d'information; déterminer si le serveur d'information est disponible; informer que le service d'information n'est pas disponible s'il ne l'est effectivement pas; et enfin, stocker les informations relatives à cette tentative d'accès. Par ailleurs, une passerelle, un serveur d'information, un système de communication et un programme informatique sont configurés pour exécuter ce procédé.
