Call screening at a hierarchical switch based on organizational membership of the parties
First Claim
1. In a telecommunication network having first and second subscribers connected to first and second telecommunication switches, respectively, a method for providing call origination screening of calls made by first subscribers to second subscribers comprising the steps of:
- receiving, at a third switch disposed at a hierarchical level above the second switch, a call setup message generated in response to a call request made by one of the first subscribers via the first switch, the call setup message including a first group affiliation parameter defining one organization of which the one first subscriber is a member and a destination number of one of the second subscribers called by the one of the first subscribers, said third switch being capable of direct call origination services;
locating a first record in a first database coupled to the third switch in response to receiving the call setup message, the located first record based on the destination number contained in the call setup message;
identifying a call screening parameter stored in said first record;
making a determination of whether the call will be allowed to terminate to the one of the second subscribers based on a comparison of the call screening parameter and the first group affiliation parameter, whereby call screening is based on membership of the one of the first subscribers in the one organization.

Abstract
A telecommunication network has first and second subscribers connected to first and second telecommunication switches, respectively. A third switch is disposed at a hierarchical level above the second switch and receives a call setup message. The call setup message includes a first group affiliation parameter defining one organization of which the first subscriber is a member and a destination number of the second subscriber called by the first subscriber. A record in a database coupled to the third switch is located in response to receiving the call setup message. The located record is based on the destination number contained in the call setup message. A call screening parameter stored in the record is also identified. A determination is made of whether the call will be allowed to terminate to the second subscriber based on a comparison of the call screening parameter and the first group affiliation parameter. Thus, call screening is based on the membership of the first subscriber in an organization.
