无线接入控制关键技术研究进展综述

摘要

接入控制技术能够有效缓解网络拥塞、保障和提高网络服务质量;在无线通信网络中,接人控制技术较有线网络将更加复杂,其中有很多有待研究解决的问题;通过对近十几年间相关文献的整理和分析,综述了无线接入控制技术发展现状及若干关键问题的研究进展;具体包括考虑下一代无线通信网络接入异构化要求下的接人控制技术,接入控制与信道分配联合研究策略等;并在文献综述和分析的基础上,提出了9个可进一步研究的无线接人控制方面的问题.%Connection (call) admission control can mitigate network congestion, guarantee and improve the QoS (Quality of Service) effectively.Connection admission control in wireless communications network is more complex than wired networks’.In this survey, we provide a number of important problems of CAC in wireless network, including next wireless network’ s CAC for heterogeneous environments, channel allocation policies.Finally, we proposed 9 problems may be in CAC future research work based on the literatures review and analysis.
