Description:

The key feature of future mobile communication systems is the ability to deliver wideband and high bit-rate multimedia services alongside the traditional radio services such as voice, messaging and slow rate data. The broad range of services expected to be supported can be divided into different Quality of Service (QoS) classes. However, the provision of such mobile multimedia services under QoS guarantees will not be possible without a utilization of the air interface resources by means of Radio Resource Management (RRM) strategies that ensure the target QoS, the planned coverage area and that offer a high system capacity.

Under this framework, the book focuses on the RRM concepts, including the theoretical background that serves as a basis for the description of specific RRM algorithms. The RRM problem for UMTS is presented, and more specifically, for the FDD mode, which is based on a WCDMA scheme. More specifically, the different aspects that are covered include:

  • Introduces the mobile communications sector and UMTS, including the evolution towards 4G systems, with an overview of the QoS concept which is key for the definition of RRM strategies
  • Offers a detailed description of the radio interface in UMTS, as the basis for the implementation of RRM strategies
  • Provides the fundamental concepts related with the development of RRM strategies in WCDMA networks
  • Analyses particular RRM algorithms in a variety of scenarios, trying to identify the key parameters and factors that influence their performance
  • Explores the evolution of UMTS towards Beyond 3G systems and the concept of Common RRM in heterogeneous networks with the aid of some algorithm examples

This comprehensive title is essential reading for engineers and managers in radio engineering departments of UMTS network operators and UMTS equipment manufacturers. It will also prove insightful to researchers in the field of 3G and Beyond 3G systems and academics in any of these areas.

商品描述(中文翻譯)

描述:
未來移動通信系統的關鍵特點是能夠在傳統無線電服務(如語音、消息和低速數據)之外,提供寬頻和高比特率的多媒體服務。預計支持的廣泛服務可以分為不同的服務質量(QoS)類別。然而,要在QoS保證下提供這種移動多媒體服務,就需要通過無線資源管理(RRM)策略來利用空中接口資源,以確保目標QoS、計劃的覆蓋範圍和高系統容量。

在這個框架下,本書專注於RRM概念,包括作為特定RRM算法描述基礎的理論背景。介紹了UMTS的RRM問題,特別是基於WCDMA方案的FDD模式。具體涵蓋的不同方面包括:

- 介紹移動通信行業和UMTS,包括向4G系統演進的概述,以及對於RRM策略定義至關重要的QoS概念。
- 詳細描述UMTS中的無線接口,作為實施RRM策略的基礎。
- 提供在WCDMA網絡中開發RRM策略的基本概念。
- 分析各種場景中的特定RRM算法,試圖確定影響其性能的關鍵參數和因素。
- 探討UMTS向Beyond 3G系統的演進以及異構網絡中的共同RRM概念,並提供一些算法示例的幫助。

這本全面的書對於UMTS網絡運營商和UMTS設備製造商的無線工程部門的工程師和經理來說是必讀的。對於3G和Beyond 3G系統領域的研究人員以及任何這些領域的學者也具有洞察力。
