Telecommunications service interactions

摘要

A basic call in a telecommunications network provides a transmission path between two users. Additional functionality is provided by a set of services, wherein, if a number of services is invoked during the same call, it is important that the services do not interact adversely with one another. For detecting service interactions, a service abstract is produced based on a Basic Call State Model and a data processing sequence performed by basic call state processing and by the services in respect of a global data item.
