接入网作为直接面向用户的“最先一公里”的网络,用户需求的多样化是城域接入网综合化的最大驱动力。在核心网趋向传送层和业务层独立发展、分别优化时,网络边缘接入层却趋向融合,允许多协议多业务综合接入,能以最低的成本灵活可靠地支持各种业务接入,扩大覆盖,适应全网的结构演变趋势。综合接入网有很多解决方案,运营商应综合考虑网络技术是否成熟可行、组网是否灵活并具有拓展性、建网成本是否具有经济性、网络和设备是否利于管理维护以及市场竞争策略等各种因素进行选择,为大客户提供综合业务、统一接入、统一维护的“一站式”服务,从而在竞争中立于不败之地。华为技术有限公司蓝玉灿的《新运营商大客户业务接入方案分析》一文对新运营商发展大客户面临的主要困难进行了分析,对几种大客户接入方案的优缺点进行了比较,对运营商选择接入方案有很高的参考价值。 相似文献

随着通信市场的蓬勃发展和用户对移动性的迫切要求,运营商在考虑本地用户环路的解决方案时也从“无线接入”发展到了“本地移动”。用户对各种新业务的需求也使现有结构的通信网暴露出种种缺点。运营商和设备制造商在共同建设“本地移动网”时逐渐意识到根本的解决方案应该是一个可以快速建设,能提供完整电信业务,并能根据用户需求和业务发展的需要自主发展、相对独立的网络。 相似文献

It is an exciting time for broadband fixed wireless with key developments in frequency bands from 1 to 60 GHz and a range of new technologies being developed. While working on these new technologies, it is easy to forget that fixed wireless access will form part of an integrated communications environment of the future where users will have one communications device working in the home, at the office, and outdoors. This article predicts the communications environment of the next 20 years and looks at the role of fixed access within that environment. This involves assessing how fixed access systems will interface and integrate with in-home wireless networks, how their architecture will enable multiservice operators to utilize the same core network across a range of different access technologies, and how they will act as a channel to carry mobile traffic originating within the building. Based on the requirements this vision and architecture implies, this article critically assesses the different fixed wireless technologies available to date and compares their capabilities to provide future-proof broadband fixed wireless platforms 相似文献

文章介绍了中国联通的多业务统一网络平台,包括多业务服务质量(QoS)保障的融合的承载平台、融合的软交换核心控制架构、多业务QoS保障的城域综合业务网络和基于IPv6的网络承载技术.依据中国联通在下一代网络(NGN)方面的实践,文章对多业务统一网络平台的先进性、效果与效益进行了总结,并指出了存在的问题.文章指出:由于未来NGN技术将向基于IP多媒体子系统(IMS)的NGN方向继续演进,同时网络承载层技术将逐步从IPv4过渡到IPv6,因此中国联通将积极探索基于IMS的NGN网络架构与组网模式,努力开展面向IPv6的应用实验与推广工作,特别是移动IPv6业务的开发和推进. 相似文献

In statistical admission control based on effective bandwidth, the network provides probabilistic guarantees for the packet loss and delay. In integrated multiservice networks like third-generation mobile networks, some traffic classes also need guarantees on the jitter. One approach is to treat jitter like delay. This letter proposes a new criterion to take into account jitter guarantees. Numerical results show that our criterion is effective and adds improvement up to 10% on the bandwidth management. 相似文献

This paper studies the uplink of the Universal Mobile Telecommunications System flexible physical layer. It recalls the semistatic approach of transport highlighting key parameters of its control and proposes an external analytic model of the mobile physical layer. This approach is adapted to radio resource management in a multiservice environment, accounting for the relationships between the link and the system levels. This paper clearly shows the impact of the rate matching mechanism on the transmission performances at link level for transport channels multiplexed in the uplink. It refines the power index notion useful at the system level as an indicator of resource consumption and transmission quality of the physical data and control channels. Integrating inter- and intramobile multiservice features with performance tables (considering environment influence, channel coding type, etc.) leads to a cost function of the transport format combinations; a valuable toot for the evaluation of the uplink multiservice cellular capacity. Several multiplexing cases are then studied under the joint aspects of quality tuning and resource consumption. 相似文献

A medium access control (MAC) protocol for wireless mobile networks that supports integrated services and provides quality of service (QoS) support is presented and evaluated via simulation. A controlled random access protocol which allows all terminals to dynamically share a group of spread spectrum spreading codes is used. The protocol provides mobile terminals the access control required for efficient transfer of integrated traffic with QoS guarantees. Two service classes are provided; "best-effort" service, with priority queueing, and reserved bandwidth circuit service. The performance of the protocol is evaluated via simulation for traffic consisting of integrated voice, data and compressed video. The performance assessment measure is packet delay. 相似文献
