A Survey on Security Aspects for LTE and LTE-A Networks

IEEE Communications Surveys and Tutorials, 2014
High demands for broadband mobile wireless communications and the emergence of new wireless multimedia applications constitute the motivation to the development of broadband wireless access technologies in recent years. The Long Term Evolution/System Architecture Evolution (LTE/SAE) system has been specified by the Third Generation Partnership Project (

Analyzing X2 handover in LTE/LTE-A

2016 14th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt), 2016
Handover procedure in LTE/LTE-A has been radically evolved when compared to the previous 3GPP standards. In particular, X2 handover is introduced to allow neighboring eNBs to handle the user mobility without the involvement of the core network. While most of the application could considerably benefit from the X2 handover performance improvement, delay ...

Tuning of LTE/LTE-A DRX parameters

2016 IEEE 21st International Workshop on Computer Aided Modelling and Design of Communication Links and Networks (CAMAD), 2016
The tradeoff between the power saving and the queuing delay in LTE/LTE-A radio devices with Discontinuous Reception (DRX) Mechanism is discussed. Two optimization problems to tune the DRX parameters are formulated. An optimal performance determined by exhaustive search over a large parameter set and a reduced parameter set, obtained by disabling short ...

On the dimensioning of LTE and LTE‐advanced networks

Transactions on Emerging Telecommunications Technologies, 2015
AbstractNetwork design consists of evaluating cell coverage and capacity and may involve many parameters related to environment, system configuration and quality of service requirements. The key parameter for cost optimised Long Term Evolution (LTE)‐based network dimensioning is to provide a tight approximation of the effective signal‐to‐interference ...

Adapting LTE/LTE-A to M2M and D2D Communications

IEEE Network, 2017
Long Term Evolution (LTE) and its revision, Long Term Evolution-Advanced (LTE-A), were designed for high performance communications between devices operated by human users. However, when these networks are used for Machineto- Machine (M2M) traffic, i.e., communications between smart electronic devices that do not need human supervision, performance is ...

LTE-advanced and the evolution of LTE deployments

IEEE Wireless Communications, 2011
The fourth generation (4G) wireless technology known as Long Term Evolution (LTE) allows cellular operators to use new and wider spectrum and complements third generation (3G) networks with higher user data rates, lower latency, and a flat Internet Protocol (IP)-based network architecture.
