Abstract: This paper addresses the limitations of the end-to-end slicing technology customized according to the 3GPP standard, which is completely dependent on the public network. An innovative "short slicing+short multiplexing" power wireless private network architecture is proposed, which integrates each link of end-to-end slicing into the power fiber optic communication network, improves the flexibility of business configuration on power communication terminals, enhances the isolation of the private network, and enhances the self configuration ability of various security encryption measures. This paper also elaborates on the measures and principles for improving the security of private networks, introduces various relevant testing situations, and explores a new path for building a power wireless communication private network from a theoretical and practical perspective, hoping to provide certain reference and guidance for research and application in related fields.
