Patent ID: 7353037

Claim:
A system for permitting a machine in a TCP/IP network to consult and/or modify subscriber parameters of mobile telephone network subscribers wherein the subscriber parameters are stored in a first node of said mobile telephone network which is separate from said system, and accessible from a second node of said mobile telephone network, said second node being authorized to obtain and/or modify said subscriber parameter in said first node, the system comprising: a first interface unit, a data storage unit, and a data processing unit, wherein: the first interface unit is operable to: receive a request made by the machine in the TCP/IP network; extract request parameters included in said request and which are necessary in order to attend to said request; and receive the requested data from the data storage unit and send the received data to the requesting machine as a response to the request, in the case that the request made is a consultation concerning a subscriber parameter; the data storage unit is physically and functionally separate from said first node in said mobile telephone network, and operative to temporarily store subscriber parameter information obtained from said first node pertaining to each one of the different mobile telephone network subscribers; the data processing unit is operative to obtain necessary mobile telephone network parameters for obtaining access to the subscriber parameter in said mobile telephone network to consult and/or modify said subscriber parameter in said mobile telephone network when said subscriber parameter to be consulted and/or modified is not contained in the data storage unit, said data processing unit comprises a request management module operative to: detect when the request made cannot be attended to by the data storage unit, and responsive to such detection: to generate a routing information request message for transmission to the mobile telephone network to access said first node of the mobile telephone network in which the subscriber is registered; and to obtain, in response, from said first node, routing parameters including the necessary mobile telephone network parameters; said necessary mobile telephone network parameters include the identity of a second node of the mobile telephone network, said second node having authority to access the first node to obtain and/or modify said subscriber parameter.
