VPN PRI OSN independent authorization levels
First Claim
1. A computerized method for determining an authorization level for a call in a communication network comprising:
- accessing, by a service control point in the communication network, a service logic database to compare a first authorization level for the call assigned at an Originating Station Number (OSN) level with a second authorization level required to proceed with the call, wherein accessing the service logic database comprises combining a Service Switch Point identifier (SWID) and a Trunk Group Number identifier (TGN) to obtain a primary key to the database, wherein the call accesses a virtual private network (VPN); and
selecting, by the service control point, an action based on a comparison of the first authorization level to the second authorization level;
wherein the combination of the SWID and the TGN is further combined with the OSN to identify the first authorization level associated with the OSN.

Abstract
The present invention provides a method for determining an authorization for a call based on an Originating Station Number (OSN) in a Primary Rate Interface (PRI) in a virtual private network (VPN) customized dialing plan. A new access type is defined enabling first authorization levels to be assigned at the level of the OSN. A service logic database at a Service Control Point stores second authorization level required to complete the call. A combination of a Switch ID (SwID) of the Service Switch Point (SSP) through which the call is being made and the Trunk Group Number (TGN) of the Private Branch Exchange (PBX) along with the OSN or range of OSNs serves as a primary key to the database. The first authorization level is compared to the second authorization level required to proceed with a call, and an action is selected based on the results of the comparison.
