A method and system for changing subscribers in communications networks.
In communications networks, more and more information providers (referred
to as content providers) are making available WML/HTML pages (data
contents) on their servers which subscribers can request and download
onto their terminal. The present invention is directed to a method and a
system which charges information transmitted via a communications network
on the basis of its content. The criteria for classifying a WML page in a
billing system are the information provider's. A "WAP gateway"
constitutes the interface between the subscriber and the WAP data world
or Internet data world. All the WML/HTML/XML content called by
subscribers passes through a WAP gateway. According to the present
invention, a network unit responds to the charging inquiries for
subscribers.
