WiMAX为运营商所带来的发展机遇

固网以及尚未获发牌照的运营商,无疑是对这个新兴技术最感兴趣者.运营商基本分三种:一是固话运营商;一是移动运营商;一是新兴运营商.固话运营商有可能采用固定WiMAX作为现有宽带接入的补充方式,一旦移动的WiMAX成熟,可能运营它同移动的3G进行竞争;移动运营商尤其是已经在3G上进行投入的,会对WiMAX持排斥态度,不过有可能借其一些技术对3G进行改造;新兴运营商本来就没有电信网络资源,可以借助WiMAX来分一杯羹,但有些国家新兴运营商管制非常严格的.

Personal communications services through the evolution of fixed andmobile communications and the intelligent network concept

New telecommunications services tend to consider fixed network subscribers' requirements as well as mobile network subscribers' requirements. On one hand, subscribers of fixed networks would like to benefit from the mobility offered in mobile networks. On the other hand, mobile subscribers would like to access to services inherent in fixed networks. Personal communications services (PCS) meet this trend while allowing fixed and mobile convergence. In this environment, the application of intelligent networks (INs) to fixed and mobile networks is very convenient to realize PCS. Thus, the natural advancement of telecommunications systems (fixed and mobile) consists in the definition of new telecommunications architectures which take into account technologies from both fixed and mobile environments. This article studies how the IN is used to support mobility and interworking for PCS. Although mobility management already exists in cellular networks like GSM, it is desirable to use the IN concept to introduce flexibility. In addition, the IN allows the introduction of new supplementary services in PCS. Furthermore, the IN concept can be utilized to provide necessary networking functions for the integration of fixed and mobile networks. This article also highlights the involvement of IN in the definition of the global communications systems such as Telecommunication Information Networking Architecture (TINA), Universal Mobile Telecommunications System (UMTS), and International Mobile Telecommunications in the year 2000 (IMT2000)

The development of personal communications

The rapid development and take-up of personal communications services has been effected as much by marketing and regulatory changes as the introduction of second generation, digital technology. The traditional boundaries between fixed and mobile and between consumer and business services have been crossed. Increasingly, customers will be offered all their communication needs from a single supplier. This will lead to composite architectures formed from several networks. In the short term, dual-mode terminals will link networks based on cordless, cellular, satellite and fixed network technologies. As intelligent network techniques are used more fully, least-cost routing and consistent service features will be achieved. Third generation standards will extend the range of services, including those utilising higher speed data. These mobile systems will provide the primary access to the `Information Society'     

Design of spread spectrum multicode CDMA transport architecture formultimedia services

We investigate a new application of the well-known spread spectrum code division multiple access (SS-CDMA) techniques to multimedia services related to the development of the next-generation wireless mobile networks interconnecting with a wireline ATM-based broadband network. Such services allow users to share novel multimedia applications without any geographical restrictions. However, since the mobile radio channel has a fixed limited bandwidth, the traditional SS-CDMA system may not be sufficient to accommodate the variable bit rate (VBR) multimedia services requested by multiple mobile users simultaneously. Moreover, the traffic load at the base station can change dynamically due to the time-varying throughput requirement of these requested multimedia services. To tackle this difficulty, a multicode CDMA (MC-CDMA) technique is proposed to provide multirate multimedia services by varying the number of spreading codes assigned to each user in order to meet its throughput requirement. In MC-CDMA, a spreading code can be used to transmit information at a basic bit rate. Users (video or data) who need higher transmission rates can use multiple codes in parallel. Meanwhile, the maximum available number of codes in the MC-CDMA system is still limited. Hence, a cost-effective dynamic code allocation scheme has then been proposed to dynamically assign an appropriate number of codes to each user for achieving the maximum resource utilization for multiuser multimedia services via the mobile radio channel. Finally, a number of real multimedia titles generated from the well-known MacroMind Director are conducted to evaluate performance     

Real-time payments for mobile IP

The mobile IP protocol has evolved from providing mobility support for portable computers to support for wireless handheld devices with high mobility patterns. A new category of micromobility protocols has been proposed to deal with the increased signaling loads that will be generated with large populations of such devices on a network. We argue that the authentication schemes presently employed in these networks do not scale well for large numbers of nodes, and that the lack of accounting procedures prevents the mass deployment of these networks. We envisage that future access networks will be operated by independent service providers, who will charge users for access to services in the fixed network but may not have long-term contractual relationships with them. These access networks may also employ a variety of micromobility protocols for fast handover support. We present a scheme based on hash chains, which allows for fast authentication of datagrams for secure updating of router entries within the access network, and real-time accounting of network usage by mobile nodes. Such a system will alleviate problems of fraud in mobile networks and eliminate the need for interoperator billing agreements.

Personal Access Communications System: fixed wireless local loopand mobile configurations and services

The Personal Access Communications System (PACS) supports wireline quality voice, voiceband data, digital data, and messaging services and is based on a low-power, low-complexity design. Operating environments for PACS include indoor and outdoor; fixed, low mobility, and vehicular mobility; and private and public access. PACS is a microcellular system providing high frequency reuse efficiency and thus is capable of supporting high traffic density. These attributes make PACS ideal for providing fixed wireless local loop and mobile services in moderate to densely populated areas, including developing countries. PACS mobile and fixed wireless local loop service can be offered by interfacing PACS with advanced intelligent network/ISDN switches, any traditional wireline switches, or with cellular/personal communications system mobile switching centers. The PACS air interface has been standardized by the American National Standards Institute     

Location-Independent Access in Mobile Systems

In this paper, we report on the design of a protocol for transparent, location-independent access in mobile systems. The protocol, termed by us Mobile Client/Server Protocol (MCSP) is an implementation of a communication layer on a mobile host and a stationary machine within the wireline network, and provides middleware functionality. The MCSP supports communication services through the client/server paradigm to transaction-oriented applications distributed between the mobile and a set of service and information brokers. To support the mobile and the wireless environment, a surrogate process is created within the fixed network to perform operations on behalf of the mobile within the fixed network. The MCSP then loosely couples the communicating entities, thus reducing the overhead associated with handoffs and disconnects, so characteristic of the mobile environment. Of particular interest is the application of the MCSP to location-based services, for example, the Intelligent Vehicle Highway Systems [1].
