China Telecom and vivo cooperated to successfully conduct the industry's first AI mobility enhancement experiment in a live network environment.

IT Home News on November 21, according to official news from China Telecom, recently, the 6G Research Center of China Telecom Research Institute and vivo completed the industry’s first AI mobility enhancement test verification based on the live network environment.

According to the introduction, this test used the terminal prototype and AI model algorithm independently developed by the research team, successfully verifying the feasibility and performance of using AI for mobility optimization

Tests show that compared with existing algorithms, the innovative AI mobility enhancement algorithm can reduce abnormal handover events (ping-pong handovers and short stays) by more than 94%, and significantly reduces the signaling interaction and wireless air interface in high-speed scenarios. Terminal energy consumption.

IT Home Note: Ping-pong handover refers to the phenomenon of multiple handovers between mobile phones in the serving cell and adjacent cells in a short period of time. Continuous switching will lead to degraded network experience and unclear voice quality.

China Telecom announced that it conducted a trial based on complex data collected from hundreds of base stations along Beijing expressways. By cleaning and processing the data in different areas and building a community-level artificial intelligence mobility model, we successfully solved the problem of frequent abnormal handover events in high-speed scenarios. This test achieved a breakthrough in multi-cell measurement signal prediction capabilities based on artificial intelligence

At present, the industry generally supports the research on wireless air interface AI mobility enhancement technology in 3GPP Rel-19, and is expected to be included in the 6G international standard as a potential 6G candidate.
