Problems solved by technology

Due to the airtightness of the high-speed rail compartment and the poor penetration of the 5G spectrum, when the user enters the compartment, the 5G base station signal next to the track becomes weak after entering the compartment, and when the high-speed train moves at high speed, the 5G signal in the compartment becomes weaker. Even weaker, leading to poor or even interrupted voice call quality for 5G users, and poor continuity experience

Abstract

The invention relates to a 5G voice service processing system and method in a high-speed railway scene, and belongs to the field of mobile communication, the system comprises a trackside macro base station and an onboard subsystem, wherein the onboard subsystem comprises an in-train small base station and an onboard switching device; the in-train small base station comprises a 5G small base station and a 4G small base station deployed in a carriage; the onboard switching device comprises customer preposed equipment CPE and a roof antenna; messages are connected to a core network and an IMS of an operator through the roof antenna and the trackside macro base station, and 5G voice communication in a high-speed railway scene is achieved. According to the invention, the small base station and the CPE are deployed in the carriage of a high-speed train, the mobile communication signal quality in the carriage under the condition of high-speed movement is improved, and the 5G user in the carriage of the high-speed train running at a high speed can realize the high-quality voice service through the voice scheme of falling back to the 4G network through the EPS FB under the condition of not opening the VoNR.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a 5G voice service processing system and processing method in a high-speed rail scene. Background technique [0002] Although the growing demand for data services is the main driving force behind the evolution of mobile communication networks to 5G, voice services are still an integral part of basic services. In the 5G era, it is also necessary to ensure the realization of voice services. However, at the current stage, none of the three major domestic operators has opened VoNR (Voice over New Radio, new air interface to carry voice calls), but make full use of the original good 4G network coverage. It adopts EPS FB (EPS Fallback, Evolved Packet Circuit Domain Fallback) method to realize. [0003] The current 5G voice implementation method is realized through EPS FB: when a 5G user makes a voice call, the voice falls back to the 4G network and is realized through V...
