Description

Terminal access and data distribution method and system based on 5G-R
Technical Field
The invention relates to the technical field of railway communication, in particular to a method and a system for terminal access and data distribution based on 5G-R.
Background
The 5G-R is short for a railway 5G special mobile communication system, and is a mobile communication system which is customized and expanded based on the 5G mobile communication system and is specially used for railway business service. Compared with commercial 5G operator networks, the 5G-R network needs higher stability and security because of being special for railway service, and has higher requirements on access management, data transmission and the like of the mobile terminal. Besides the authentication flow of the 5G standard to the SIM card, the secondary authentication to the terminal equipment is also added. In the secondary authentication, different transmission authorities are required to be given to different types of terminals, so that unauthorized access of the terminals is avoided.
VPN is known collectively as Virtual private network, which provides a private network through a public network. So that the user's device can send and receive data through the public network as in the private network, so called virtual private network.
Compared to data transmission of public networks, the VPN security model provides:
1) Confidentiality, the encryption of the transmitted content, even if the network traffic is sniffed at the packet level, the attacker will only see the encrypted data.
2) Sender authentication to prevent unauthorized users from accessing the VPN.
3) Message integrity to detect any tampering with the instance of the transmitted message.
The VPN may assist remote users, corporate branches, business partners and suppliers in establishing trusted secure connections with the corporate intranet and ensuring secure transmission of data. Meanwhile, an authentication flow can be added when the VPN connection is established so as to realize access authentication of the terminal. However, it has the following drawbacks:
1) The VPN needs to repackage and encrypt all data transmitted by the user at the sending end according to its implementation principle, and unpack and decrypt the data at the receiving end, where the operation procedure may cause the original data to change. For railway service, the reliability of data is particularly important, and the adoption of VPN can bring risk to the integrity of service data, and simultaneously, trouble is brought to the problem tracing when the service is in problem.
2) The VPN needs to perform secondary processing on all data packets according to its implementation principle, so that the delay of data processing is increased, railway service has higher requirements on the delay, and the processing delay added by the VPN may affect the service.
3) The VPN secondary processing of data packets also causes data expansion, increasing the pressure on the link transmission bandwidth. The 5G-R network also belongs to a bandwidth limited system due to the limited physical frequency band, and the data expansion caused by VPN can greatly influence the loadable service capacity of the 5G-R network.
