Net-Net SBC IMS Support

The ETSI TISPAN NGN defines several subsystems that make up the NGN architecture. The model for the target NGN architecture is depicted below. The Oracle Communications Session Border Controller is an integrated session control, policy enforcement and media management solution that incorporates functional components of the IP multimedia subsystem (IMS), the Resource and Admission Control Subsystem (RACS) and functions necessary for connecting with other IP networks/domains. The functions of the Oracle Communications Session Border Controller within the NGN architecture are divided into the interconnect border functions and the access border functions. The diagram below depicts the mapping of these functions across IMS architecture.
