An Area Restriction Scheme Based on TAC Control Policy for 5G Private Network

With the rapid development of 5G technology, industry users in the process of accelerating to the digital intelligent transformation of the network coverage quality, delay, uplink capacity and stability and other performance has an urgent need. 5G private network has technical characteristics such as open network architecture, virtual intelligent orchestration of network elements, and air interface capabilities. It can provide a dedicated network with differential performance, autonomy and control, agility and security on the basis of meeting the requirements of network performance indicators. In this paper, we discuss an area restriction technology based on tracking area code (TAC) control policy for 5G private network. Based on the design of 5G private network architecture and TAC control policy, we focus on proposing the related 5G private network area restriction technology. This scheme can provide a unified data interaction channel for all kinds of wireless intelligent devices, and continuously integrate all kinds of sensing terminals with sensing and monitoring capabilities into all aspects of the industrial production process. Finally, a typical application scenario is presented to demonstrate the effectiveness and safety of the proposed scheme.
