Embodiment Construction

[0032] The present invention will be described in more detail below in conjunction with the accompanying drawings. The same reference numerals are used for the same elements in different drawings.

[0033] Fig. 1 is a schematic block diagram illustrating a system in which a mobile terminal operates according to the method of the present invention.

[0034] The system in FIG. 1 includes a mobile network 110, such as a GSM network, which has multiple base stations, one of which is shown as 111. The base station 111 communicates with a user's mobile terminal 300, such as a mobile phone. The system further includes a client computer 122 with a web client. Both the client computer 122 and the web server 124 are operatively connected to a computer network 120, preferably the Internet.

[0035] A gateway 116 is provided for operably interconnecting the mobile network 110 and the computer network 120.

[0036] A server 112 on the service provider side is operatively connected to the mobil...
