    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (254 KB)  

    Summary form only given. The government of the Hong Kong Special Administrative Region founded the Hong Kong Applied Science and Technology Research Institute Company Limited (ASTRI) in 2001 to capture the promises of technological advances for Hong Kong through world-class applied research. In September 2004, ASTRI completed its five-year strategic plan with an objective to become Greater China's most customer-focused applied research institution by continuously producing a substantial volume of world-competitive intellectual properties, and transfer them cost-effectively to the burgeoning local technology industries of Hong Kong, Pearl River Delta and the rest of China, and in so doing, position Hong Kong as a vital driving force for technology in the region. The plan calls for ASTRI to utilize Hong Kong's unique comparative advantage as the only first-world economy in all of China to build a distinctive human resource edge in technology, and execute a totally customer-focused approach toward R&D that would produce substantial industrial impact in a predictable manner year in and year out. As a research institution, ASTRI's R&D activities focus on four closely interrelated technological domains - IC design, wireless communications, enterprise and consumer electronics and next generation material and packaging technologies. By engaging in the pursuit of customer-focused excellence in these highly innovation- and knowledge-intensive fields, we will strive not only to execute our organization's impact-driven missions but also to provide the challenging working environment for our employees to accelerate their personal development and advance their careers in and beyond ASTRI. At ASTRI, we believe organizational achievement and individual growth are inseparable, and it is the execution of this belief that will ultimately determine the outcome of our plans.

  • Perspectives on photonic integration

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (132 KB)  

    Summary form only given. Photonic integration can be viewed as a replacement technology from two perspectives; replacing discrete optical solutions with improvements in cost, size, and power, but also enabling the evolving replacement of network functionality that has historically been provided in the electronic domain. This talk will explore the status of integration in the world of photonics, both from technological and market or application perspectives. The tenuous analogy with the history of electronic integration is examined to gain a better understanding of the expectations and role of photonic integration. Additionally, this talk will discuss the evolving role that photonics is playing in communications networks, and the impact of this evolution as a driver for integration. View full abstract»

  • Convergent communication technologies and services with context awareness

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (230 KB)  

    Summary form only given. The worlds of universal telephony and best-effort data networking, two disparate communication services in the past, are converging to one in which the user's multimedia experiences are becoming increasingly rich, personalized, spontaneous and interactive. The so-called converged network has set the stage for user-centric broadband services. For example, on-demand media is expected to encompass a multiplicity of information sources (from MP3 download and digital audio broadcast to mobile video), networks (from dialed-up to WiMax) and terminal devices (from multimedia PDA with 3G mobile to HDTV). This calls for innovations in efficient and intelligent content processing, distribution and information management. Even more fundamentally, as service personalization (in the general term of context which includes situation, location and availability) becomes the critical differentiation factor in the market, the new convergent communication may demand an architectural focus that will prove indispensable in the trustworthy support and management of context-aware services. In this talk, we articulate for such a vision and point out technical challenges that have to be harnessed in order to realize the vision of right information and right service at the right time.

  • A survey on wireless/wireline integration

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (176 KB)  

    Summary form only given. Telecommunication operators started to address the issues of wireless/wireline integration since mid 1990s. Back then, the emphases were (1) how to make wireline voice features such as call waiting, call forwarding, three way calling, voice mails available to wireless subscriber; (2) how to add mobility to wireline services via calling card, prepaid service, and personal toll free number; and (3) how to merge network infrastructures such as wireless and wireline intelligent networks (WIN, CAMEL, AIN, and IN) to maximize resource sharing. While the work from mid 1990s is still continued (e.g., wireless E-911, number portability are still under deployment in many parts of the world), the wireless/wireline integration today has taken a new form due to the emergency of (1) new wireless access technologies and (2) network evolution toward a convergent IP architecture. This talk will survey the most recent development in this area of wireless/wireline integration. We will look at the short-term wireless/wireline integration efforts by telecommunications operators such as Verizon, SBC, BellSouth, BT, and KT etc. We will also look at more exciting, long-term efforts in standards bodies such as 3GPP, ETSI TISPAN, and ATIS of using IMS (IP multimedia subsystem) as the core for this integration. Moreover, we believe devices and service management will play an important role in making this integration happen and will comment about their necessity in the talk. View full abstract»

  • Evolving to wireless and wireline convergence - an overview of IMS

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (159 KB)  

    Summary form only given. Originally specified by 3GPP to support IP multimedia services for mobile users, IMS (IP multimedia subsystem) has become the foundation for future wireless and wireline convergence. IMS offers service providers the opportunity to build an open IP based service infrastructure that will enable an easy deployment of new rich, personalized multimedia communication services mixing telecom and data services. IMS is access agnostic so that a common IMS based service platform can be built to support various access mechanisms such as DSL, cable, wireless (CDMA, UMTS) and WiFi/WiMax. As such, IMS promises a cost-effective evolution path to future wireless and wireline convergence that meet next-generation service demands and requirements. This talk provides an overview of IMS from market, technology and business perspectives. We first look at market drivers for next-generation services supported by IMS. The IMS functional architecture being developed in standards and solution for a wireless and wireline converged network are then examined at a high level. The talk concludes with a few key findings from IMS business cases that demonstrate the potential CapEx/OpEx savings and revenue increase made by IMS over conventional point solutions.

  • End-to-end QoS in IMS enabled next generation networks

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (156 KB)  

    Summary form only given. It is widely acknowledged that the convergence is the way to evolve the existing wireline and wireless networks towards next generation networks. IP multimedia subsystem (IMS) stemming from the Third Generation Partnership Project (3GPP) is presently deemed as being instrumental to support wireline and wireless convergence (also referred to as fixed mobile convergence (FMC)). However, even though the notion of IMS is access agnostic, lots of open issues still need to be investigated for integrating various access technologies into IMS framework, one of significant concern is the framework and mechanisms to support end-to-end QoS in the IMS and NGNs. This talk will discuss the challenges and requirements of resource and admission control for supporting end-to-end QoS in the converged NGNs. It will address the architecture and key mechanisms to perform policy control, call admission control and resource management etc. in IMS enabled NGNs over various wireless and wireline access networks, e.g. UMTS/CDMA, DSL and cable network etc. Finally the related IMS/NGN standard activities in ITU-T, TISPAN and 3GPP will be introduced.

  • The utility of compound wireless services

    Page(s): 29 - 30
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (302 KB) |  | HTML iconHTML  

    Summary form only given. This talk will provide examples within a data services class that have the potential of substantial capital returns. This class of data services is termed compound wireless (mobile communication) services or CWS's. Compound wireless services are beyond 3G and are not now available. Nor are they planned for 3G wireless systems. However, they represent a natural extension beyond 3G and provide an incentive for users/subscribers to desire 3G data services. It is believed that compound wireless services make the wireless telecommunications terminal an indispensable data tool and subjugate voice communications to a secondary service. That is, the CWS class contains many "killer" application services. A compound wireless service is a service consisting of linked component services. When invoked, a CWS causes the component services to be executed in a sequence prescribed by the CWS. The following CWS example is intended to assist in defining this class of services. Consider having a severe time constraint for driving a vehicle between two geographic points. This may apply to commuting between one's home and a place of employment, or for a limousine driver to arrive at an airport in time for a passenger's flight, or for a chartered bus to reach its tour destination in a timely manner, etc. The main three component services employed to achieve this need are presented. The user/subscriber programmed wireless service consists of continual iterations of these three services until the destination is reached. The iteration sequence can consist of the steps, which are discussed in this paper. View full abstract»

  • Optical performance monitoring applications in transparent networks

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (144 KB)  

    Summary form only given. Optical performance monitoring (OPM) is an enabling technology for highly transparent and reconfigurable networks. Simple OPM functions such as channel monitoring and discovery are requirements in re-configurable systems. Large transparent regions of the network either created by long transmission distances or transparent pass-through at cross-connect or add-drop nodes create new challenges in terms of both locating and diagnosing faults. OPM devices can provide greater visibility into signal health and enable remote troubleshooting. We examine advanced OPM methods and technologies with potential to enhance fault management. Clear technology requirements are determined by identifying specific applications. For example, a typical fault isolation cycle in which the OPM measurement history is reviewed in response to end terminal performance monitoring (PM) alarms. The required sensitivity for both Q-factor and optical signal to noise ratio (OSNR) monitoring is determined by the need to correlate the OPM readings with the end terminal alarms. Another potential application for OPM is quality of service (QoS) monitoring in systems that utilize all-optical regeneration. In this case dedicated per-channel monitoring is required and therefore integration with the regeneration device is desirable. An OPM device that is derived from an SOA-based wavelength converter and regenerator is described as a promising solution. By focusing on the application, we identify OPM technology needs for enabling new advances in transparent networks. View full abstract»
