ABSTRACT:
A method of acquiring potential tariff charges assessed by wireless service providers to a mobile subscriber prior to registration is disclosed herein. The method includes transmitting a request for tariff information by the mobile terminal over a control channel to a candidate service provider. The candidate service provider determines an applicable tariff charge based on various factors such as roaming status, compulsory fees etc. The ensuing tariff charge is then transmitted back to the mobile terminal via the control channel. Subsequent tariff inquiries are made to other potential candidate service providers accessible by the mobile terminal. Once tariff information from all candidate service providers has been received, the mobile terminal may initiate registration e.g. with the cheapest service provider. The tariff information is able to be obtained prior to registering with a service provider, thus costs associated with registration are eliminated.
