In 3G, the server platform of IP multimedia subsystem (IMS) offers multimedia service to the multimedia clients through the exchange of authenticated key agreement (AKA) scheme. Since the IMS service is transmitted over public networks, the server and client of IMS shares a common session-key via the execution of AKA scheme to secure the communication service over a public network. Though there are some identical steps involved in the key authentication Scheme of IMS, the communication efficiencies of IMS server and client are still conciliating. Besides, it is having the issues of insecurity and session compatibility dealt with the real time transport protocol (RTP). To resolve the issues of IMS, this paper proposes three novel schemes: (1) The first scheme is multimedia server-client authentication scheme and its purpose is to mitigate the packet congestion on the networks; (2) The second scheme is traffic on background and its purpose is to analyze the signal congestion, bandwidth consumption and network utilization of the system; and (3) The last one is fault detection index and its purpose is to prevent the SIP vulnerabilities, like bye and invite. In addition, we integrate the proposed and existing authentication schemes, such as EPS-AKA, AP-AKA, UMTS-AKA, X-AKA, S-AKA and so on., in the IMS server and client environments to testify the metrics, namely round trip time, call response time, packet generation, flow analysis, RTP session, network utilization, throughput analysis, bandwidth utilization and flooding attack detection realistically.

“…It can integrate heterogeneous wireless network technologies such as the 802.11 series wireless local area network (WLAN), 802.16 series network (Worldwide Interoperability for Microwave Access, WiMAX) and even in Long Term Evolution (LTE). Based on IP transport and SIP, IMS provides ubiquitous services anytime, anywhere and even at movement [2,3]. Thus, users can access amount of multimedia applications through various access technologies with guaranteed the Quality of Service (QoS) and different service features under common framework.…”

Cognitive Radio (CR) is an innovative wireless sensing technology which can improve efficiency of spectrum usage. Based on CR, Cognitive network (CN) further focus on end-to-end communications for the global optimization and policy enforcement. However, there is a lack of global control channel or middleware for cognitive optimization in CN environment. In this paper, we proposed a Cognitive IP Multimedia Subsystem framework called CogIMS, which consists of benefits from CN and IP multimedia subsystem (IMS). In this framework, the cognitive optimization is modeled as a service over IMS architecture. By adopting the proposed service-oriented framework, the global optimization is simple to achieve under standardized architecture and the computation requirement is reduced from user to core network. Finally, we simulate wireless users who using services to compare CogIMS with CN and IMS. The simulation results show that the proposed CogIMS can achieve the optimization of wireless resource allocation with different network situations.
