Abstract
Simultaneous use of heterogeneous radio access technologies to increase the
performance of real-time, reliability and capacity is an inherent feature of satellite-5G
integrated network (Sat5G). However, there is still a lack of theoretical characterization
of whether the network can satisfy the end-to-end transmission performance for latencysensitive service. To this end, we build a tandem model considering the connection
relationship between the various components in Sat5G network architecture, and give an
end-to-end latency calculation function based on this model. By introducing stochastic
network calculus, we derive the relationship between the end-to-end latency bound and
the violation probability considering the traffic characteristics of multimedia. Numerical
results demonstrate the impact of different burst states and different service rates on this
relationship, which means the higher the burst of arrival traffic and the higher the average
rate of arrival traffic, the greater the probability of end-to-end latency violation. The
results will provide valuable guidelines for the traffic control and cache management in
Sat5G network.
