Combined home location register and service control point for a cellular telecommunications network
First Claim
1. A system for interfacing cellular telecommunication database functions with intelligent network (IN) functions without accessing the public switched telephone network, and without modifying mobile switching centers (MSCs) in order to implement IN services, said system comprising:
- a home location register (HLR) component for storing mobile subscriber information and location information on mobile stations;
a service control point (SCP) component for storing IN services for mobile subscribers, said SCP component being directly connected to the HLR component; and
a cellular telecommunication interface based on IS-41 between said HLR component and said SCP component, said interface sending requests for IN services from the HLR component to the SCP component, and sending results of the requested IN services from the SCP component to the HLR component.

Abstract
A system in a cellular telecommunications network that combines the functionality of a home location register (HLR) with the functionality of a service control point (SCP) in a single functional unit without accessing the public switched telephone network. The system allows cellular subscribers the degree of mobility that they desire while coordinating the interaction between existing cellular subscriber services and new intelligent network (IN)-derived services. A home location register (HLR) component stores mobile subscriber information and location information on mobile stations. A service control point (SCP) component stores IN services for mobile subscribers. A cellular telecommunication interface based on the IS-41 standard is utilized for communication between the HLR component and the SCP component.
