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 latency-sensitive 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.
