发明名称 Method and system for enabling a mobile user to manage calls
摘要 A method includes provisioning a mobile user with usage minutes for usage calls. The method includes determining whether the mobile user and a telephone user either belong to the same provider or different providers after a call between the users is initiated. The call is designated as a usage call if the users belong to different providers. If the call is a usage call, then the mobile user is advised that the call is a usage call and the number of usage minutes remaining and an affirmation from the mobile user is required to complete the call.
