Latency Evaluation for Messaging Service at the Network Edge

Short Messaging Service (SMS) is expected to continue to be an important use case in the fifth generation (5G) system. 5G messaging service is optimized for massive Machine Type Communications which impose different requirements. The requirements for low latency, efficient bandwidth utilization, and location awareness may be fulfilled by using Multi-access Edge Computing (MEC) technology. MEC brings cloud capabilities at the network edge. The paper studies two MEC deployment scenarios in radio access network, and provides performance analysis on the signaling latency for SMS provided by MEC.
