连接高铁乘客-中国移动

When travelling on China’s high-speed trains, passengers oftendisconnect from the dedicated wireless network due to intermittentcoverage, signal interference, their device’s configuration and/ornetwork overload. To address these issues, China Mobile hasdeveloped and launched a “5G-A High-Speed Rail VIP acceleration”package on the “Guangdong-Shenzhen-Hong Kong”high-speed rail link. Executive Summary link. Entertainment services arealso enhanced, so that playersof online games, such as Honorof Kings, enjoy more responsiveconnections.

Toaddress these issues, ChinaMobile has developedand launched a “5G-A High-Speed Rail VIPacceleration” package onthe “Guangdong-Shenzhen-Hong Kong” high-speed raillink. China Mobile says the accelerationsolution is set to benefit 20million passengers by the endof 2025. From a commercial The solution introduces a new AIalgorithm into the packet corenetwork that can accurately Challenge– business people need reliableconnectivity on high-speed trains As of March 2025, China had 48,000 km of high-speed railwaylines, ranking the country first in the world. In Guangdongprovince, 1,048 daily trains carry an average of 30 millionpassengers a month. China Mobile’s market research foundthat more than 30% of the passengers travelling on this line areenterprise employees and managers that need reliable highspeed Internet access during their rail journeys. conventional public network.This drift results in frequenthandovers and poor serviceexperience. At the same time, it isimportant to reduce the intrusionof normal users’ devices ontothe high-speed rail dedicatednetwork, particularly aroundstations when the trains aretravelling at relatively low speeds.Finally, improved accelerationefficiency is required to optimisethe experience for high-speed railpassengers, while ensuring theacceleration is both noticeableand perceptible to users. need to be overcome Firstly,there is a need to prevent thedevices used by passengers fromswitching from the dedicatedhigh-speed rail network to the When travelling on high-speed trains, passengers oftendisconnect from the dedicatedwireless network due tointermittent network coverage,signal interference and the wayin which devices select networks.Additionally, demand can be toohigh, leading to the dedicatednetwork becoming overloaded.To provide a high-quality serviceexperience for high-speed railpassengers, several challenges Solution– intelligent high-speed rail acceleration AI algorithms, the partnerslaunched a pilot among internalusers in Guangdong. Finally,at the end of April 2025, ChinaMobile Guangdong commerciallylaunched the 5G-A High-SpeedRail VIP acceleration package onthe “Guangdong-Shenzhen-HongKong” high-speed rail section.The complete journey frominnovation incubation tocommercialisation is illustrated inthe graphic below. In the second half of2024, China Mobilebegan to research anintelligent high-speedrail acceleration solution.During the period, ChinaMobile Research Instituteled the formulation andspecifications of the overalltechnical architecture, ChinaMobile Group GuangdongCompany provided on-site scenario supportand Huawei participatedin the development andintegration of networkequipment. Finally, at the end of April 2025, ChinaMobile Guangdong commercially launchedthe 5G-A High-Speed Rail VIP accelerationpackage on the “Guangdong-Shenzhen-Hong Kong” high-speed rail section. After two rounds of technicalverification, which fully confirmedthe feasibility of the solutionand the effectiveness of the –The AM-PCF sends the RFSPpolicy to the RAN, enablingnetwork selection based onthe RFSP policy. High-speedrail VIP users are preferentiallyassigned to the dedicatednetwork to ensure exclusiveuse of the dedicated network. The new acceleration systemis illustrated in the followingdiagram. In the intelligent packetcore network, a new AI algorithmin the NWDAF (network dataanalytics function) is used toaccurately identify high-speedrail passengers and normal users.It then issues
