Benefits of technology

This technology allows users' services (such as email) to safely transmit their data over an internet connection while still being able to access them from different devices connected by wires or wireless networks. By obtaining these configurations needed for transmitting this type of data between two parties, they cannot easily intercept any sensitive parts of the communication content without compromising its security level.

Problems solved by technology

This patented describes a problem where separating two parts called CP's and Unified Physic Block Group (UMB)-RS_Unit) requires complex hardware configurations due to their unique characteristics. Exchanging these components takes up valuable space within an operator's cabroom area. To address this issue, some solutions involve virtualizing certain elements like CPU cores and networking devices, allowing access ports to share all available computing power without overloading any part(Physics Hardware Node Base Hub, PMUB)). However, existing systems lack sufficient efficiency when handling user requests requiring faster response times than what was previously expected based upon the assumed maximum transfer speed supported by each component.

Abstract

The present invention provides a secret key sending method and device, a parameter sending method and device, a user plane (UP), and a control plane (CP). The secret key sending method comprises the steps of: obtaining necessary configuration parameters of data safety transmission of a user surface, wherein the configuration parameters comprise a common root secret key KgNB, a movement next hop parameter NH, a safety algorithm identifier and an assistant value of a sub secret key corresponding to each data wireless bearing DRB configured to the terminal; generating independent sub secret keysfor each DRB according to the configuration parameters; and sending the independent sub secret key generated by each DRB to the terminal. According to the invention, the problem is solved that how toachieve the safety transmission of a user business data flow in a condition of CP and UP physical separation so as to achieve the effect of safety transmission.
