Ericsson announced that NTT Docomo has selected its AI-based optimization solution for its nationwide radio access network (RAN).

The AI-based Performance Diagnostic solution will apply machine learning and problem-solving techniques to classify cell performance issues and recommend changes. NTT Docomo’s planning and optimization teams will be able to evaluate the solution’s output to speed up optimization efforts accurately.

Ericsson and NTT Docomo conducted trials of AI-based optimization solution in 12 cities. The Ericsson Performance Diagnostics solution achieved 98 percent accuracy in classifying performance issues. The commercial operation to cover nationwide network is planned for March 2020.

Hozumi Tamura, executive vice president of NTT Docomo, said: “We have worked on service area expansion and communication quality improvement in an effort to provide comfortable communication areas to our customers. Leveraging AI will further improve network quality.”
