AI Technical Summary

Technical Problem

Existing technologies cannot achieve unified identity authentication and efficient switching between satellite DVB and 5G heterogeneous networks, resulting in service interruptions and billing difficulties, and cannot meet the continuous communication needs of mobile carriers between the two networks.

Method used

A gateway function conversion module is used to manage the handover of user terminals between satellite DVB and 5G networks. Through the coordination of 5G base stations and target satellite beam serving cells, a mapping table is used to convert signaling and data formats to ensure the continuity of data transmission and the consistency of identity.

Benefits of technology

It enables seamless switching between satellite DVB and 5G networks, reduces switching downtime, ensures continuous transmission of service data, supports unified billing, and improves user experience.

Abstract

The invention relates to the technical field of satellite communication, in particular to a satellite DVB and 5G different system access network switching management method and system, a user terminal sends a wireless connection measurement report during 5G communication, a 5G base station judges whether to switch a network according to the wireless connection measurement report, and a switching request is sent to a gateway function conversion module through a newly added inter-network interface. And the target satellite beam serving cell judges whether to accept or not, and after acceptance, the gateway function conversion module converts confirmation information and returns the confirmation information to the 5G base station. Then, the target satellite beam serving cell allocates resources, the 5G base station sends an instruction to trigger the user terminal to switch and processes a data packet, the gateway function conversion module converts a data format and then sends the data packet, the user terminal initiates access to complete switching, and efficient switching of different-system networks is achieved.
