Diameter in the IMS
The 3GPP standards body has adopted Diameter as the primary signaling protocol for AAA and mobility management in the IP Multimedia Subsystem (IMS). The IMS is the service delivery environment for real-time multimedia services for the 3rd Generation wireless network and is also an ideal architecture for service convergence across fixed, wireless, and corporate enterprise networks. IMS offers a secure, mediated access to value-added services and network resources inside a managed core IP network while providing open interfaces for third party developers and enterprise-based applications that need access to the trusted carrier.
