COMMUNICATION SYSTEM FOR THE CENTRALIZED MANAGEMENT, VIA A VIRTUAL OPERATOR, OF CALLS OF SUBSCRIBER TERMINALS CONNECTED TO HOST COMMUNICATION NETWORKS

摘要

A communication system (SC) comprises i) a centralized piatform (PC) that can be used by at teast one virtual operator and that comprises at least equipment and services management means (EG1), subscriber/subscription data management means (EG2) and a call server (SA), responsible for jointly managing the controi plan layer, and it) at least one distributed media gateway (PMi) connected to the centralized piatform (PC) via a backbone network (RF)I and responsible for the interconnection between the centralized piatform (PC) and a routing center (Ai), of a communication network (RMf) of an associated network operator, responsible for routing calls concerning communication terminals (UE) connected to its communication network (RMi) and managed by the centralized piatform (PC) and for controlling a user plan layer of the environment of the system (SC).
