Abstract
Abstract A telecommunications switching system is disclosed which integrates intelligent network (IN) services with regular telephone services. A service control processor (101), which implements the IN services, is also periodically made aware of regular network functions. The SCP then allocates resources for IN calls based upon not only the amount of IN calls, but rather, based upon the total network conditions; i.e. IN calls, regular telephone calls, faulty transmission lines, telephones taken off hook, etc.
