  • Converged IP/MPLS Backbone Networks for 2G and 3G Voice Services Integration
    White Paper Converged IP/MPLS Backbone Networks for 2G and 3G Voice Services Integration With Release 4 of the third-generation (3G) architectural standards for mobile networks, mobile operators can now reduce costs, enhance revenues, and decrease time to market for new voice-over-IP (VoIP) and traditional voice services. When mobile operators deploy a new split architecture to support voice, and consolidate 2G and 3G voice over an IP/Multiprotocol Label Switching (IP/MPLS) backbone network, existing 2G and newer 3G voice traffic can greatly benefit from simplified operations, multigigabit speeds, transport efficiency, quality of service (QoS), traffic engineering, and all of the features required of carrier-class networks. This paper describes how IP/MPLS technologies support the emerging VoIP infrastructure in mobile networks to facilitate the convergence of 2G and 3G mobile voice services, including the evolution of the VoIP network from the split architecture in 3G Release 4 to the introduction of the IP-enabled media gateway, and how available technologies from Cisco Systems® can help operators effectively manage converged IP/MPLS mobile networks. Summary Most mobile operators are now firmly focused on consolidating transmission and management of a broad range of mobile services deployed on disparate networks to reduce their capital expenses (CapEx) and operating expenses (OpEx), increase business agility, and more easily deploy new 3G IP-based services. Cisco® has helped both wireless and wireline carriers accomplish such consolidation while greatly enhancing performance and network features by converging disparate networks into one common IP/MPLS core to support both existing and future services. The Cisco IP Next-Generation Network (IP NGN) architecture for mobile operators is a roadmap to realize the vision of next-generation mobile services – the delivery of data, voice, and video anywhere and anytime across virtually any access technology.

Roadmap Introduction Megaco/H.248 and VoIP Design architecture Design considerations OPNET implementation Call flow scenarios Simulation results Conclusion Copyright © 2004 OPNET Technologies, Inc. Confidential, not for distribution to third parties. 2 Introduction Voice over IP (VoIP) is getting popular in both commercial and residential markets. It enables a telecommunication company to cut costs by allowing a single network to transmit both data and voice traffic. Offers inexpensive rate for long distance calls. Voice quality resulting from packets transmitted over the IP network is comparable to the voice quality in Public Switched Telephone Network (PSTN). To control and manage the voice traffic, Megaco/H.248 signaling protocol was introduced by Internet Engineering Task Force (IETF) and International Telecommunication Union (ITU).

  • Cisco Service Exchange Solution for IP Multimedia Subsystem (IMS)
    White Paper Cisco Service Exchange Solution for IP Multimedia Subsystem (IMS) Enabling Next-Generation Multimedia Communication Services Service providers are looking to increase their revenue and lower their costs by transitioning to next-generation networks that support voice, video, and data services across multiple types of network access—including wireless, wireline, and cable. The Cisco Service Exchange Solution for IP Multimedia Subsystem (IMS) helps service providers deploy a complete array of real-time, personalized business and consumer multimedia services over any access network. THE CHANGING LANDSCAPE OF COMMUNICATIONS Consumers and businesses today enjoy a wide range of choice for communications, entertainment, and online services, which they can access in many different ways. Many can buy their broadcast video and video on demand from a cable operator, a satellite TV provider, or even a DSL provider offering IPTV. High-speed data (HSD) is available from cable, DSL, and Wi-Fi providers. Cable operators and “best-effort” voice-over- broadband service providers are entering the telephone services market, and mobile virtual network operators (MVNOs) are pursuing both consumer and enterprise mobile wireless markets. With so many services and so many different choices for delivery, competition is fierce. Service providers try to offer as many services as possible to reduce customer turnover and increase revenue, because their market penetration for any particular service may be relatively low. To reduce risk or cost of entry, some service providers are forming new relationships to deliver new services to new customers. For example, voice carriers are partnering with content providers to enter the multimedia services market.

  • Analysis of Ip Multimedia Subsystem for 3G Networks
    MEE10:08 ANALYSIS OF IP MULTIMEDIA SUBSYSTEM FOR 3G NETWORKS BY Mohammad Rezaul Hossain Morshed Md. Humayun Kabir A Thesis Presented in partial fulfillment of the requirements for the degree of Master of Science in Electrical Engineering with specialization in Telecommunication Blekinge Institute of Technology December 2009 Blekinge Institute of Technology School of Engineering Department of Telecommunication Systems Supervisor: Alexandru Popescu Thesis Abstract The IP Multimedia Subsystem is seen as the promising solution for the next generation multimedia communication. The IP Multimedia Subsystem will make Internet technologies almost anywhere, anytime and on any device such as email, web, instant messaging, presence and videoconferencing. Presence is one of the most important basic services in IMS. It is the service that allows a user to be informed about the reachability, availability and willingness to communicate with other user. Push to talk over Cellular (PoC) is one more service in IMS that allows users to engage in immediate communication with one or more users. Instant Messaging (IM) is the service that allows a user to send some content to another user in near real time. In this thesis work, we have discussed overall IMS architecture and identity the major issues to improve the existing protocols in IMS for better system performance. Our work is centered on Presence service, Push to talk over Cellular, Instant Messaging and IMS session setup. In this thesis three possible session establishment scenarios in a mobile environment is compared by using an analytical model. The other problem areas in optimizing presence service, dimensioning a PoC service and analyzing service rate of IM relay extensions in IMS are identified.
