Availability Analysis of Multi-Connectivity for Providing URLLC

Ultra-reliable low latency communication (URLLC) in mobile networks is expected to be enabled by a combination of multi-connectivity and multi-access edge computing (MEC). In this letter, we develop an availability model that can be used to characterize multi-connectivity to the MEC and the combined effect of MEC server location and the physical topology. The model incorporates the effect of the wireless link in the connection and illustrates the need for multi-connectivity to achieve high levels of availability.
