Generic service coordination mechanism for solving supplementary service interaction problems in communication system

摘要

A generic service coordination mechanism solves feasible service interaction problems taking into account real-time processing constraints within telecommunication networks. The coordination mechanism limits service interaction complexity within an active basic call by preventing interactive service accessibility as early as possible following the request of a new service. Data defined on the basis of a general allocation, an individual subscriber allocation, and a service allocation is manipulated during provision and withdrawal, activation and deactivation, and invocation and operation of service procedures. Requests to initiate, read, change, or erase subscription and interaction data are processed internally according to a coordinator state machine. Requests are terminated by a response which includes a decision to continue basic call processing and service processing based on allocated services and encountered service interaction criteria such as restriction or dependency criteria.
