Abstract

A subscription record within a telecommunication system is sub-divided into three separate registers, namely, a user, a subscription and a terminal register. The use of three separate registers within the system allows several terminals to be associated with one user, several users to be associated with one terminal, several subscriptions to be associated with one user, and several users to be selectively associated with one subscription. The subscription records include a list of allowed users for each subscription account. Additionally, the subscription records include a schedule that defines allowable usage time for each user. The user records include a schedule which defines what subscription accounts will be charged at specified times during the week.
