METHODS, SYSTEMS, AND COMPUTER PROGRAM PRODUCTS FOR A HIERARCHICAL, REDUNDANT OAM & P ARCHITECTURE FOR USE IN AN IP MULTIMEDIA SUBSYSTEM (IMS) NETWORK

摘要

Methods, systems, and computer program products for a hierarchical, redundant OAM & P architecture for use in an IP multimedia subsystem (IMS) are disclosed. According to one aspect, the subject matter described herein includes a system for managing an Internet protocol multimedia system (IMS) network. The system includes a network operations, administration, maintenance, and provisioning (OAM & P) entity for communicating with an operator's network, a system OAM & P entity associated with the network OAM & P entity, and at least one message processing entity associated with the system OAM & P entity for processing signaling information and for implementing at least one application. The system OAM & P entity receives OAM & P information from one or more message processing entities and communicates at least some of the received OAM & P information to the network OAM & P entity. The network OAM & P entity receives OAM & P information from the system OAM & P entity and communicates at least some of the received OAM & P information to the operator's network.
