A network infrastructure to support PCS

This paper describes an AIN/ISDN-based network architecture for a local exchange carrier (LEC) that can support flexible and feature-rich PCS offerings, and discusses the C interface to an ISDN switch which allows radio systems to access network switching and service control functions. It discusses the assignment of functions to network elements and to software applications which could run in a service control point to support PCS in general and the C interface in particular. It also identifies key ISDN and AIN switching system capabilities needed to support the C interface. It illustrates the use of ISDN and AIN interworking to support mobility. The architecture supports both voice and data services, and is extensible to support multiple radio system and mobility management requirements.
