Solution – IMS Service Platform for Creating Value-Added Services

The NGN is composed of security/ QoS management functions and service delivery functions centered on the IMS platform. These together form the service platform for the NGN and are positioned as the core functions of NGN services.

In the case of IMS products, we started commercialization very early on and improved the reliability, availability and scalability of the products by utilizing the past achievements of SIP servers for fixed networks. Pursuing compliance with standard specifications such as 3GPP/3GPP2. we verified interconnections through trials with Multiple carriers and eventually succeeded in commercializing them as IMS platform infrastructures.

Furthermore. we are developing and commercializing next-generation SIP servers as IMS platform products cored on next-generation networks. These products feature the following.

  • Implementation of highly reliable Carrier Grade Extension
  • Interface and Hardware Compatibility with Standardization such as the NGN standard of ITU-T/ TISPAN as well as with the IMS/MA4U (Multi Media Domain) standards of 3GPP/3GPP2.
  • Fixed Mobile Convergence (FMC) compatibility enables service enhancement based on a close convergence of fixed and mobile networks

In the future, we will continue to contribute to the creation of new communication modes for users and expansion of businesses for communication carriers by providing optimum NGN environments centered on next generation SIP servers. as well as provide service solutions that are available on the NGN.

For communications carriers and service providers. finding a way in which to create. develop and introduce outstanding and innovative services efficiently and quickly to the NGN has become an important topic. It is the SUP that serves as the response to these needs for the development and delivery of new services. which is why it is attracting attention as a foundation for achieving various functions ranging from the development of services to their introduction, maintenance/administration, and accounting and user management.

Under these circumstances. NEC regards an SOP that pays attention to SIP adopted as a core technology of the NGN as the SIP-SUP. and is currently commercializing practical SIP application servers using it. The SIP-SUP has the following features.

  1. Quick Service Development/Introduction
    User-friendly programming APIs and communication APIs such as Java, .NET, XML. HT1P or SOAP are used as open APIs to further increase the development speed of new services.
  2. Simple Programming
    Complicated SIP referred to as control procedures are hidden so that SIP interface verification and communication testing, which have up until now been necessary each time a service has been developed. are no longer required.
  3. Flexible System Configuration
    Application servers that provide and control services individually are offered at a level higher than that of commonly used SIP application servers (Call Control, Presence. Media Control, etc.). [his simplifies the addition of services and enables configuration of the system according to the type and scale of service.

In the future, we will construct various NGN services on these service platforms and position them among our core business operations.

Solution - Optical Access System Enabling High-Quality And High-Speed Data Communications

The means of broadband connections to communication carriers and service providers is shifting from metallic access using telephone lines to optical access using optical fibers featuring high-speed data communication capability. In addition, demand is on the rise for a triple-play system in which a single broadband connection simultaneously provides telephone, broadcasting and Internet services.

An optical access system is composed of an Optical Line Terminator (OL f) installed by the communications carrier or service provider and the Optical Network Unit (ONU) installed in the office or household of the subscriber. Optical access can make the uplink and downlink transmission speeds symmetrical as well as achieve long-distance, high-quality ultrahigh-speed data transmission that is less dependent on line conditions as compared to metallic access.

The optical access method includes the Single Star (SS) and Passive Optical Network (PON) technologies, and the latter is currently being used more predominantly. Research on PON technology began in the eighties. and commercialization of Gigabit-PON (G-POM will begin after ATM-PON (APON) and Broadband PON (B-PON). In Japan, commercialization of Gigabit Ethernet-PON (G6PON) is already underway.

At NEC, we are developing products based on technology acquired as a result of our past experience in PON technology development which in turn enables us to provide solutions for both GE-PON and G-PON.

In addition to their compliance with the IEEE standard, our GE-PON products also have the following features:

  1. over 20-km optical transmission using an optical module with 29dB dynamic range capability:
  2. support of max. 512 ONUs with a single OLT, and:
  3. provision of multiple user authentication methods including 802.1x.

NEC will continue the promotion of R&D into advanced technological solutions in the held of optical access and make positive proposals for the promotion of highly reliable systems that allow us to deal flexibly with the services and applications of the next generation.
