Abstract: In a method of personalizing access to the Internet via an access network and an Internet service provider, the access network allocates an Internet caller profile when setting up a telephone call to access the Internet. The access network transmits the Internet caller profile to the Internet service provider and the Internet service provider personalizes access to the Internet in accordance with the Internet caller profile. Functions of an access network such as the intelligent network are used to personalize Internet access in a fashion that is transparent for the user and independent of the Internet service provider.
