Radio Access Network Security - A simplified explanation of the abstract
This abstract first appeared for US patent application 18029495 titled 'Radio Access Network Security
Simplified Explanation
- The patent application is about a network node that is used in a wireless communication network. - The network node is configured to handle different data radio bearers of a wireless device in multi-connectivity operation. - The network node configures multiple central unit user planes (CU-UPs) of a disaggregated radio network node to handle the data radio bearers. - The user plane traffic is processed by different CU-UPs based on different security keys. - The network node also configures different distributed units (DUs) of the disaggregated radio network node to serve different data radio bearers.
Original Abstract Submitted
A network node () is configured for use in a wireless communication network (). The network node () configures multiple central unit user planes, CU-UPs, (-UP) of a disaggregated radio network node () to handle different respective data radio bearers (--N) of a wireless device () in multi-connectivity operation, with security processing of user plane traffic by different CU-UPs (-UP) being based on different respective security keys (). In some embodiments, the network node () configures different distributed units, DUs, of the disaggregated radio network node () to serve different respective ones of the data radio bearers (--N).
