Due to the coexistence of different generations of mobile radio technologies, more and more mobile network operators are keen on deploying multiple radio technologies on a single cell site and carry their traffic over a common transport network. This paper studies such a collocated multiradio system: collocated LTE and HSDPA. Firstly, we investigate the potential gain by using a shared transport network...
This paper proposes an analytical model for dimensioning transport bandwidths in the Long Term Evolution (LTE) access network. In this work the criterion for dimensioning is the transport network delay QoS (at the packet level). The presented analytical model takes into considerations the key features of the LTE radio interface and the use of Differentiated Service (DiffServ) QoS scheme in the LTE...
This paper presents analytical models to dimension the transport bandwidths for the S1 interface in the Long Term Evolution (LTE) Network. In this paper, we consider two major traffic types: elastic traffic and real time traffic. For each type of traffic, individual dimensioning models are proposed. For validating these analytical dimensioning models, a developed LTE system simulation model is used...
This paper proposes efficient analytical models to dimension the required transport bandwidths for the Long Term Evolution (LTE) access network for the elastic Internet traffic (which is carried by the TCP protocol). The dimensioning models are based on the use of Processor Sharing queuing theory to guarantee a desired end-to-end application QoS target. For validating the analytical dimensioning models,...
This paper presents dimensioning of an IP-based UMTS Terrestrial Radio Access Network (UTRAN) with multiple Node Bs connected to one RNC, where the applied QoS architecture is based on Differentiated Service (DiffServ) with an integrated Weighted Fair Queue (WFQ) and Strict Priority (SP) scheduling. To provide an appropriate network dimensioning for guaranteeing a desired end-to-end QoS, a general...
In allusion to the technical issues in traditional Ethernet, The article researches Multi-operation platform plan based on telecommunication Ethernet in order to solve the problem of IP (Internet Protocol), Ethernet, TDM (Telemetric Data Monitor), and other multi-operation delivery. It also extends the metro area to other wider area, such as expansibility, business protection, QoS(Quality of Service)...
The next generation networks are expected to provide heterogeneous services with higher data rates and diverse quality of service (QoS) requirements. For the major challenges we are confronted with nowadays, this paper establishes cross-layer architecture among application (AP) layer, media access control (MAC) layer and physical (PHY) layer, upon which an integrated radio resource management (RRM)...
This paper introduces a new wireless architecture that creates ultimate freedom for dynamic channel allocation (DCA). The architecture is implemented based on the capabilities of cognitive radios. In the current wireless systems, users should subscribe to a service provider (vendor) and receive the service through the spectrum assigned to that vendor at all times. Hence, we call the current wireless...
