[object Object],[object Object],[object Object]

The document discusses creating an ecosystem for next generation networks. It notes challenges in implementing IMS infrastructure due to the "chicken and egg" issue of needing users and applications. It proposes MIMOS can help by providing a platform and tools to connect application developers, content providers, and telcos, in order to offer a variety of applications and help break the vicious cycle. The goal is to build an NGN ecosystem in Malaysia through these efforts.

NGN Network (ETE 521 L10.2)

Nazirul Islam Zico

The document discusses the transition to Next Generation Networks (NGNs). Traditional telecom networks are being replaced by IP-based networks capable of integrating different access technologies and services. This allows for the convergence of fixed, mobile, and data networks. NGNs aim to reduce costs through infrastructure optimization while creating new revenue sources by offering converged services like triple play bundles. However, successful business models for NGNs remain uncertain and will depend on demonstrating clear benefits to customers.

IMS presentation

Elyes Naouar

The document discusses the IP Multimedia Subsystem (IMS), which is an architectural framework for delivering internet protocol (IP) multimedia services. IMS allows convergence of voice, video, messaging and other multimedia applications over an IP-based network. It provides a standardized service platform that can enable operators to offer new revenue-generating services to subscribers. Key components of the IMS architecture include the Call Session Control Functions (CSCFs) which handle registration, session management and other core operations using the Session Initiation Protocol (SIP). IMS enables delivery of multimedia services to users independent of their access network, whether on fixed or mobile devices.

RAHUL KAUSHAL

The document discusses next generation networks (NGN) and convergence. It defines NGN as a packet-based network that can provide telecommunication services using multiple broadband access technologies and QoS-enabled transport, with service functions independent from underlying transport technologies. NGN simplifies networks and uses an IP-based core with separation of transport and service layers. The document also discusses how convergence is occurring at the network, service, industry, and device levels, and how convergence and NGN allow services to be accessed seamlessly across different networks through multiple platforms.

Hafeth Dawbaa

The document discusses next generation networks (NGN) and the IP Multimedia Subsystem (IMS). It defines NGN as a packet-based network that provides telecommunication services to users using multiple broadband transport technologies. Key characteristics of NGN include supporting a wide range of real-time and non-real-time services, broadband capabilities with end-to-end quality of service, and independence from underlying transport technologies. The document also outlines some of the challenges in deploying NGN, such as quality of service and security issues, and provides a high-level overview of the NGN architecture.

Ims, Ip Multimedia System

manymbaboy

The document provides an overview of IMS (IP Multimedia Subsystem), including its history, architecture, layers, benefits, and relationship to SIP (Session Initiation Protocol). IMS allows convergence of voice, video, and data over an IP-based network using SIP and other IETF protocols. It has a service plane for applications, a control plane for session management, and a media plane for transport.

The document discusses how IMS (IP Multimedia Subsystem) and SOA (Service-Oriented Architecture) can help reduce the time needed to implement new services. IMS provides an open standard architecture for converged multi-media services across networks. SOA allows applications and services to be built in a modular way and connected through published interfaces, improving flexibility and integration. Combining IMS with SOA principles like loose coupling, reuse, and abstraction allows services to be deployed more quickly.

Ngn sec

draacon

IP NGN security provides a framework for securing next generation networks through a hierarchical model. It describes key security principles of visibility, control and business relevance. The framework involves iteratively developing security policies through threat and risk assessment. It then outlines six fundamental security actions - identify, monitor, correlate, harden, isolate, and enforce - which apply policies to increase visibility and control through relevant technologies and improve security, resiliency and reliability for subscribers and operators.

Telecordia Ims Presentation Expections And Challenges

Jeanne Rog

The document discusses the IP Multimedia Subsystem (IMS) industry including its status, expectations, challenges and key players. IMS is an NGN solution that aims to standardize network interfaces to avoid proprietary technologies. Major standards bodies contributing to IMS include 3GPP, 3GPP2, IETF and ETSI. Research shows the US leads in prioritizing IMS deployment to reduce costs by removing legacy infrastructure. Trials are underway to test interoperability between networks as service providers work towards full IMS implementations.

Enabling Enhanced Services Through IMS Technology

The NTT Next Generation Network Deployment in Japan

International Institute of Communications

NTT's Next Generation Network Development Takashi Ebihara of NTT presented on NTT's next generation network (NGN) development at a 2008 conference. Key points included: 1) NTT plans to deploy its NGN commercially in 2008 in Tokyo and Osaka and expand coverage to all fiber access areas by 2010. 2) NGN combines advantages of traditional telephone networks and IP networks with features like enhanced reliability, security, quality assurance and open interfaces. 3) NTT will collaborate with partners through forums and test beds to jointly develop innovative new services leveraging NGN's capabilities.

MPLS

Elyes Naouar

MPLS (Multi Protocol Label Switching) is a mechanism for data transport that operates on the data link layer below protocols like IP. It is mainly used to forward IP datagrams and Ethernet traffic. MPLS overcomes limitations of traditional IP routing by bringing the intelligence of routing with the performance of switching, and supports VPNs, QoS, and effective bandwidth management. MPLS works by assigning short fixed-length labels to packets, and routers use the labels stored in forwarding tables to make switching decisions instead of long IP addresses.

All-IP Telecom Networks

alrohily

This document discusses the transition to all-IP telecom networks. It begins by reviewing the evolution of telecommunications from past technologies like GSM to the present with 4G/LTE networks and the future of 5G. It then explains that all-IP networks will converge different services like data, voice and multimedia onto a single IP-based network. This will impact the telecom market by increasing competition and allowing new entrants. The document also summarizes the growth of the Saudi telecom market in mobile, fixed and broadband services. It provides overviews of the marketing, business operations and personnel planning needed to support all-IP networks.
