The Access Control Mechanism Of Wireless Base Station For LTE Industry Applications

LTE technology is one of the core technologies of contemporary wireless mobile communication.With the characteristics of high bandwidth,low delay and full time online,LTE technology has been widely used in different industries.However,with the rapid development of content services,the explosive increase of multimedia services,especially video and other large capacity services,causing the network congestion,and users in the system with high packet loss rate.Therefore,facing different LTE industry application scenarios,we need to design a reasonable access control mechanism to mitigate network congestion and improve the throughput of the network.Therefore,in this papera,for the LTE based public safety network and LTE based intelligent neighbourhood area network,we respectively develope two new access control mechanism:a selective admission control mechanism based on load measurement and the admission control mechanism based on smart grid traffic characteristics.Our goal is to optimize the distribution of LTE resources,reduce congestion and improve resource utilization in two industries.In the public security network,this paper proposes an admission control model with selection factor,which can adjust the difficulty degree of the new bearer access system,and improve the spectrum resource utilization.For the smart grid communication network,this paper establishes a multi-sources ON/OFF traffic model based on self-similarity to calculate the effective bandwidth.To guarantee the bandwidth for different type of services we propose a non-cooperative game model,reasonably allocating spectrum resources.Finally,through using the optimally allocated bandwidth as the threshold,we develop a novel admission control scheme orienting the multi-services access in NAN.In a word,this paper concentrates on the admission control mechanism for wireless access networks under different industry scenarios,making up for the lack of the characteristics of the industry scenes in the existing research literatures,solving the problem of network congestion,optimizing the network resource allocation.Further improve the network performance,and ensure the users’ quality of service.
