Abstract
The preferred embodiments described herein provide a method for NPA split processing on a service control point. These preferred embodiments can be used to overcome problems encountered during a permissive dialing period of an NPA split and yield several advantages over prior art approaches to this problem. Specifically, these preferred embodiments do not require changes to be made to an existing call processing record to include a pointer to a new call processing record identified by a telephone number with a new NPA. Additionally, unlike prior approaches that require changes to be made to all incoming query messages to a service control point, these preferred embodiments do not require extra processing for services that are not NPA sensitive.
