Leveraging Decoupling in Enabling Energy Aware D2D Communications

Downlink/Uplink decoupling (DUDe) in LTE net- works has caught the attention of researchers as it provides better uplink SINR and reduced power consumption per device due to decoupled connection of a device with the Macro (in downlink ) and a small cell (in uplink). These characteristics of DUDe c an be exploited to encourage more D2D communications in the network. This paper first proposes a model to estimate decoup ling region within which a device is allowed to perform DUDe. Then , it formulates an equation to calculate the total power saved by devices due to decoupling. Finally, the extra area due to decoupling which can be used to enable D2D pairs is calculate d. Simulation results are shown based on different simulation scenarios for different objectives for better understandi ng the idea proposed

Impact of Slice Granularity in Centralization Benefit of 5G Radio Access Network

5G Mobile network will reap the benefits from key technologies like Software Defined Networking and Network Function Virtualization. Cloud Radio Access Network architecture (Cloud RAN) is proven to be a promising architecture, but fully centralized Cloud RAN imposes a great bandwidth requirement in the fronthaul link. Different functional split options for 5G RAN have been proposed which lead to a trade-off between centralization and bandwidth requirement. Functional split at different granularity such as per cell, per logical network (slice), per user, or per bearer, have been an area of interest. To explore the effect of slice granularity in adaptive splits for slices, we formulate slice centric functional split in 5G RAN as an ILP to maximize centralization of baseband processing. By varying the slice granularity from macro slicing to micro slicing, we observe how slice centric split can impact centralization benefit of the network. We show that with increasing slice granularity slice centric split can render more centralization benefit in some scenarios but a trade off exists between centralization benefit and migration cost in the network which should be carefully considered in real deployment scenario. © 2020 IEEE

A Cloud Native Solution for Dynamic Auto Scaling of MME in LTE

Due to rapid growth in the use of mobile devices and as a vital carrier of IoT traffic, mobile networks need to undergo infrastructure wide revisions to meet explosive traffic demand. In addition to data traffic, there has been a significant rise in the control signaling overhead due to dense deployment of small cells and IoT devices. Adoption of technologies like cloud computing, Software Defined Networking (SDN) and Network Functions Virtualization (NFV) is impressively successful in mitigating the existing challenges and driving the path towards 5G evolution. However, issues pertaining to scalability, ease of use, service resiliency, and high availability need considerable study for successful roll out of production grade 5G solutions in cloud. In this work, we propose a scalable Cloud Native Solution for Mobility Management Entity (CNS-MME) of mobile core in a production data center based on micro service architecture. The micro services are lightweight MME functionalities, in contrast to monolithic MME in Long Term Evolution (LTE). The proposed architecture is highly available and supports auto-scaling to dynamically scale-up and scale-down required micro services for load balancing. The performance of proposed CNS-MME architecture is evaluated against monolithic MME in terms of scalability, auto scaling of the service, resource utilization of MME, and efficient load balancing features. We observed that, compared to monolithic MME architecture, CNS-MME provides 7% higher MME throughput and also reduces the processing resource consumption by 26%

Experimental Evaluation of YouTube Performance on MPTCP-based LTE-WLAN Integration

Soaring demand for high-quality and data-intensive services such as video streaming pushing the limits of the cellular networks. In due time, the bandwidth requirement for these services will exceed the cellular network capacity. Now, it is vital to aggregate cellular (licensed) and WLAN (unlicensed) bands to keep pace with the increasing high bandwidth requirement. Multipath TCP (MPTCP) is a transport layer protocol which can be used to aggregate available bandwidths of multiple networks at a multi-homed User Equipment (UE). We evaluate the performance of LTE-WLAN Integration(LWI) using MPTCP in terms of Quality of Experience (QoE) of YouTube Ultra-High Definition (UHD) videos in a test-bed. As YouTube server does not support MPTCP, we use an architecture with MPTCP proxy which enables the use of MPTCP services to multi-homed UEs. To analyse the QoE, we have developed an application to search and play the YouTube videos. This application monitors the key performance metrics to evaluate QoE in terms of Mean Opinion Score (MOS). Our results show significant improvement in MOS with LWI compared to WLAN or LTE alone. Also, our results indicate that more data is offloaded through Wi-Fi when using lowest RTT (Round Trip Time) scheduler in MPTCP

Performance Study of Multi-access Edge Computing Deployment in a Virtualized Environment

Various real-time, latency-sensitive, and high-speed mobile applications are evolving as 5G applications. These applications are realized using Multi-access Edge Computing (MEC) and Network Function Virtualization (NFV) technologies in the 5G system. MEC platform, MEC service, and MEC application are the main components of an MEC Framework. NFV Orchestrator, Virtualized Infrastructure Manager (VIM), and virtualization technologies such as Virtual Machines (VM) and Containers are the main pillars of the NFV technology. In this paper, we study the impact of the virtualization technologies in the deployment of the MEC framework and its components while. We also study the impact of virtualization technologies on NFV and MEC KPIs such as onboarding time, instantiation time, MEC service and application response times. The experiments and its analysis show that containers perform better than VM to instantiate/terminate MEC components in the NFV framework. The observed MEC service KPIs show that the edge application's performance will be improved to meet the QoE of the applications irrespective of the virtualization technology used. These results can be used as a reference while deploying the MEC components based on their granular functionalities. © 2020 IEEE
