User Signaling Servers for ATM-Based PCS Networks
Different models for user service profile management exist in telephony wireless intelligent networks and in data networks. This paper presents a balanced solution to this problem by providing PCS subscribers access to a new element called a user signaling server. Two types of user signaling servers, home and visitor, are defined to provide users both the flexibility of the data networking model in which services are requested as needed as well as the option to subscribe to IN-based services as in the telephony model. This approach provides mobile PCS users savings in air interface and computing resources, reduces signaling load (air interface and network) and call/connection setup delay.
