Research and design of distributed testing framework for 5G network
Yugang He, Fengli Wang, Qian Sun, Lin Tian, Yuanyuan Wang · 2023
As the 5G network continues to evolve with micro-services, the protocol implementation in the network is decentralised to individual network elements, with multiple network elements collaborating to provide services to the terminals. The functional testing of the network therefore requires the simultaneous testing of multiple network elements.The current test system cannot test multiple network elements simultaneously and has the problem that test anomalies are difficult to locate.This paper proposes a distributed testing framework for 5G networks, which is based on the TTCN-3 testing framework as a prototype and designed using keyword-driven technology and remote procedure call (RPC) technology based on C/S architecture.The framework has proven to have the following advantages: good scalability of the test nodes, the ability to test multiple network elements simultaneously, and the ability to locate test anomalies at the element signalling level.
