ABSTRACT:
In a telephone network, a service control point is called by a switching center, if a flag has previously been set by some event (e.g. call charges crossing a threshold or the leaving of a voice mail message) when a call is being established or terminated. The switching center then operates in accordance with commands returned by the service control point. If no flags have been set, the service control point is not called and the call is treated by the switching center in a default manner.
