Design of a 5G Multimedia Broadcast Application Function Supporting Adaptive Error Recovery
The demand for mobile multimedia streaming services has been steadily growing
in recent years. Mobile multimedia broadcasting addresses the shortage of radio
resources but introduces a network error recovery problem. Retransmitting
multimedia segments that are not correctly broadcast can cause service
disruptions and increased service latency, affecting the quality of experience
perceived by end users. With the advent of networking paradigms based on
virtualization technologies, mobile networks have been enabled with more
flexibility and agility to deploy innovative services that improve the
utilization of available network resources. This paper discusses how mobile
multimedia broadcast services can be designed to prevent service degradation by
using the computing capabilities provided by multiaccess edge computing (MEC)
platforms in the context of a 5G network architecture. An experimental platform
has been developed to evaluate the feasibility of a MEC application to provide
adaptive error recovery for multimedia broadcast services. The results of the
experiments carried out show that the proposal provides a flexible mechanism
that can be deployed at the network edge to lower the impact of transmission
errors on latency and service disruptions.Comment: 14 pages, 10 figure
