The flexible access authorization feature for wireless telecommunicatio n systems enables network operators and/or service providers to dynamically authorize a user to receive services for which the subscriber has not previously subscribed or which are not supported in the user's home network. This is accomplished by enabling a user to expand and contract their portfolio of available communication services on an as needed basis to enable wireless users to use their user mobile terminals and obtain the services which they need, regardless of the user's location in the wireless communication network and regardless of the present set of services for which the user is authorized. The flexible acces s authorization feature is accomplished by real time interaction among the relevant functional entities of the wireless telecommunications system to obtain new or additional user information to execute the flexible access authorization log ic to decide on access authorization to a selected service. The flexible access authorization logic can reside in any of a number of network entities and ca n examine a number of conditions to determine access authorization for a user with respect to a selected service, including: time-dependency, location- dependency, account billing limitations, and other factors.
