Method and apparatus for intelligent network call handling in a telephone exchange
First Claim
1. A method for filtering calls in a switch system, the switch system including at least two access subsystems and at least one interconnection subsystem comprising the steps of:
- storing a list of active filtering criteria in each of said at least two access subsystems;
receiving an incoming call at at least one access subsystem of said at least two access subsystems;
determining whether the incoming call matches any of the active criteria stored in the at least one access subsystem;
applying a filtering method associated with a matched active filtering criteria if the incoming call matches any one of the active filtering criteria;
determining whether a call should be blocked as a function of said filtering method; and
causing said access subsystem to block the incoming call if it is determined to block the incoming call as a function of the filtering method;
storing a list of active filtering criteria in each of said at least two access subsystems;
storing a filter method associated with each of the active filtering criteria in the interconnection subsystem;
inputting a change to the interconnection subsystem to the list of active filtering criteria and broadcasting the change to each access subsystem; and
storing the change in the list of active filtering criteria in each of said at least two access subsystems.

Abstract
A method and apparatus for operating on intelligent network calls in a telephone exchange with multiple access subsystems and an interconnection subsystem is provided. A list of intelligent network criteria is stored in each access subsystem. When an incoming call is received the access subsystem determines whether the incoming call matches one of the intelligent network criteria stored in the access subsystem. If a match occurs the access subsystem performs an intelligent network function. Intelligent network function may include filtering the call. If filtering is to occur a filtering method associated with the matched active filtering criteria is applied to determine whether a call should be blocked as a function of the filtering method.
