PCS subscriber profile data and information requirements
Gregory D. Schumacher · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1996
Enhanced services for mobile subscribers are currently undergoing significant growth. This growth will continue to increase as more wireless serviceproviders enter the marketplace. Profit margins for basic service will fall as competition increases leading to interest in higher margin enhanced services. Likewise subscribers will demand enhanced services to further increase productivity over basic wire service. However there are limitations in today's network infrastructure defined by inter-system interface standards such as IS-41, GSM and WACS. These network limitations prevent enhanced services from being offered in the seamless and geographically ubiquitous fashion subscribers are familiar with in basic wireless service. This paper examines what are the needs of wireless enhanced services to be provided as subscribers want them. This paper then looks at the major inter-system interfaces available for mobility and call control in terms of how well these enhanced service needs are fulfilled.
