1. A method of routing calls in a communication system comprising the steps of:
- providing a PSTN interconnect at each of a plurality of base station controllers and at a mobile switching center;
intercepting, at a control intercept in communication with the mobile switching center and the base station controllers, PSTN command information communicated between the mobile switching center and the base station controllers; and
transferring the PSTN command information to a PSTN interconnect at a base station controller for providing local call service.

Abstract
A method and apparatus is provided for locally routing calls in a communication system. The method and apparatus provide PSTN interconnects (N, P, Q,) at each of the base station controllers (11, 14) and at the mobile switching center (12). A control intercept (13) intercepts PSTN command information being communicated between the mobile switching center (12) and the base station controllers (11, 14), and routes the PSTN command information to a PSTN interconnect (N, P) at a base station controller (11, 14) when local call service is required.
