第三代移动通信分层网络中数据用户的自适应分配策略

Adaptive assignment strategies for data users in 3G networks

移动数据业务是未来移动通信业务发展的重点,如何在有限的频率资源上为用户提供大容量和高数据率的数据业务是第三代移动通信需解决的重点问题。针对分层网络结构的特点,建立了相应的系统模型,对基于速率的分配策略(VAS)、基于数据量的分配策略(DAS)、分配策略中的运用准则以及自适应分配策略等进行了深入探讨。为解决移动通信分层网络结构中用户数据流量变化和提高系统负责能力具有重要的实际意义。

Future mobile communication fakes mobile data services as development emphases,and how to provide big capacity and high rate data services for users in limited frequency resource is important matter in the third generation mobile communication.This paper firstly sets up corresponding system model depending on the characteristic of hierarchical overlay network architecture,and then explores the assignment strategies for mobile data users based on velocity and the quantity of data to be transmitted by each user,their application rules and adaptive assignment strategies and so so.The main contributions of the paper show the practical significance for the capability of varying with thequantity of user data and improving performance of system load in mobile communication hierarchical overlay networks.
