Services for tomorrow´s PCS

Personal Communications Services (PCS) provides terminal, personal, and service mobility - the ability of an end user to access his/her telecommunications services in any location and the ability of the network to locate this end user as he/she moves. Today\´s telephone customers have come to expect a menu of "bell and whistle" services that provide offerings like custom calling features, voice mail, and operator services; that may be generally referred to as supplementary services. In order for PCS to become widely accepted by the public more than basic wireline or wireless services may be required. In addition to the bells and whistles of today, supplementary services that provide manageability and security of a PCS offering should be made available to the end user. This paper provides a view of an end-to-end PCS network as a reference for the reader. The paper then shifts the focus to the two areas of supplementary services that may be implemented in a PCS offering and provide additional revenue and/or preserve current revenue: personalized call management and fraud detection. Personalized call management includes services such as message delivery and call screening; features that may provide opportunities for additional revenue. Fraud detection addresses the need to preserve revenue via improved billing and fraud detection capabilities
