ICNP - Service Boost: Towards on-demand QoS enhancements for OTT apps in LTE
2013 21st IEEE International Conference on Network Protocols (ICNP), 2013Co-Authors: K. Samdanis, D. Kutscher, T. TalebAbstract:This paper introduces the concept of dynamic Service Boost and proposes deployment solutions in mobile networks focusing on the 3GPP Long Term Evolution (LTE) architecture. The main idea is to introduce a time bound preferential service to subscribers based on predefined service contracts. By applying a light-weight, dynamic Quality of Service (QoS) control, operators achieve both, efficient network utilization and adequate QoS for users and content/application providers. This helps operators to use resources more efficiently, for example to enable a more efficient capacity sharing in the presence of increasing mobile traffic. We initially investigate the impact of Service Boost on Over-The-Top (OTT) traffic transmitted without any specific QoS guarantees over the so-called Default Bearer in LTE. Then we consider the design and analysis of a Service Boost architecture and framework for managing and prioritizing service requirements for certain applications within LTE. Finally, we elaborate the realization of Service Boost through congestion accountability.

GLOBECOM - Design of an Enhanced Bearer Buffer for Latency Minimization in the Mobile RAN
2019 IEEE Global Communications Conference (GLOBECOM), 2019Co-Authors: Rajeev Kumar, Andrea Francini, Shivendra S. Panwar, Sameerkumar SharmaAbstract:5G will transform the cellular network from a generic supplier of high-speed data to a flexible, super-fast, and highly-reliable communications medium that supports diverse sets of services and applications. Low packet latency is a critical enabler for the interactivity features of many of these applications, but maybe compromised in saturated packets buffers if the buffers are oversized, as is often the case in the RLC layer of the 3GPP RAN stack. To protect all interactive applications from excessive buffering, we completely revise the flow-control component of a prior solution of ours that splits the per-Bearer buffer between the RLC and PDCP layers and regulates the packet flow between the two buffers so that queue build-up in the RLC layer is constrained. On a cellular link shared with a greedy TCP flow, our new enhanced Bearer buffer (EBB) design with continuous flow control (CFC) reduces the latency of packets from low-bandwidth interactive applications by at least 80% compared to previous EBB versions, and by orders of magnitude compared to the Default Bearer configuration with a large RLC buffer. The CFC also benefits throughput-intensive interactive applications like augmented and virtual reality because it confines the buffering within the PDCP layer, where it can be effectively controlled with active queue management techniques.

ICC - 5G virtualized radio access network approach based on NO Stack framework
2017 IEEE International Conference on Communications (ICC), 2017Co-Authors: Jie Zeng, Jinjin Gong, Liping Rong, Xin Su, Jing WangAbstract:Cloud radio access network (C-RAN) centralizes several baseband units to form a pool, which is the primary form of the wireless network virtualization. Some aspects of C-RAN are always developing, such as the processing capacity and multiple radio access technology (multi-RAT) convergence. In this paper, the Not Only Stack (NO Stack) framework, as a virtualization approach, is suggested to be employed in 5G radio access network (RAN). NO Stack is programmable, flexible, and sustainable, while adopting the mature virtualization technology to achieve a fully virtualized RAN (vRAN). With RAN slicing and network orchestration schemes, the baseband processing and storage resources could be sliced and orchestrated to realize the multi-RAT convergence and flexible reconfiguration. By reconstructing the dedicated and Default Bearer establishment procedure in long term evolution (LTE), NO Stack framework reduces the signaling and delaying respectively. Seen from the analysis and demonstration, the vRAN based on NO Stack can support multi-RAT convergence and flexible networking, as well as reduce the signaling and delay.
