Method and system for determining authorization levels in a virtual private network (VPN)
First Claim
1. A method comprising:
- determining whether a call originated from an originating station associated with a virtual private network, the call originating via a private branch exchange associated with the virtual private network, the call originating on behalf of a first user of a plurality of users associated with the virtual private network;
querying, with a service control point, a private-number table based on a trunk group identifier representing the private branch exchange and an originating station identifier representing the originating station to obtain a private number assigned to the first user, wherein the private-number table associates a switch identifier and a plurality of trunk group identifiers with the private number, the switch identifier representing a service switching point;
matching an identifier of the first user of an incoming transaction capability application part message to an identifier of the originating station entry in the private-number table;
identifying an authorization level associated with the private number assigned to the first user;
comparing the authorization level to a threshold to determine whether to prompt the first user to enter an authorization code; and
providing the authorization level associated with the private number to the service switching point, the service switching point to process the call according to the authorization level.

Abstract
Example methods, apparatus and articles of manufacture to determine authorization levels in a virtual private network are disclosed. A disclosed example method includes determining whether a call originated from an originating station associated with a virtual private network, the call originating via a private branch exchange associated with the virtual private network by a first user of a plurality of users associated with the virtual private network, querying a private-number table based on at least one of a switch identifier representing a service switching point, a trunk group identifier representing the private branch exchange, or an originating station identifier representing the originating station to obtain a private number assigned to the first user, and providing an authorization level associated with the private number to the service switching point, the service switching point to process the call according to the authorization level.

4. A service control point comprising:
-
a memory to store a private-number table; and a processor to control a call originating from an originating station of a private branch exchange, the call originating on behalf of a first user of a plurality of users associated with a virtual private network, the processor to control the call by; accessing the private-number table based on a trunk group identifier representing the private branch exchange and an originating station number representing the originating station to obtain a private number assigned to the first user, wherein the private-number table is to associate a switch identifier and a plurality of trunk group identifiers with the private number, the switch identifier representing a service switching point; matching an identifier of the first user of an incoming transaction capability application part message to an identifier of the originating station entry in the private-number table; identifying an authorization level associated with the private number assigned to the first user; comparing the authorization level to a threshold to determine whether to prompt the first user to enter an authorization code; and providing the authorization level associated with the private number to the service switching point, the service switching point to process the call according to the authorization level. - View Dependent Claims (5, 6)

7. A tangible computer-readable storage medium excluding propagating signals, the tangible computer-readable storage medium comprising instructions which, when executed by a processor, cause the processor perform operations comprising:
-
determining whether a call originated from an originating station associated with a virtual private network, the call originating via a private branch exchange associated with the virtual private network, the call originating on behalf of a first user of a plurality of users associated with the virtual private network; querying a private-number table based on a trunk group identifier representing the private branch exchange and an originating station identifier representing the originating station to obtain a private number assigned to the first user, wherein the private-number table associates a switch identifier and a plurality of trunk group identifiers with the private number, the switch identifier representing a service switching point; matching an identifier of the first user of an incoming transaction capability application part message to an identifier of the originating station entry in the private-number table; identifying an authorization level associated with the private number assigned to the first user; comparing the authorization level to a threshold to determine whether to prompt the first user to enter an authorization code; and providing the authorization level associated with the private number to the service switching point to enable the service switching point to process the call according to the authorization level. - View Dependent Claims (8, 9)
