context: Considering the MOCN for broadcast usecase in 5G, common mechanisms to derive MSK and MTK are required across the different PLMNs. This solution proposes three possible mechanisms for MOCN key identification. This proposal considers configurations of common fields for MOCN. For example, setting Key domain ID to a default value for all PLMNs involved in the MOCN. Figure 2 illustrates these proposed mechanisms. MOCN MSK 1) Key domain can be set as default values or set to zero or new MOCN ID can be introduced instead of key domain ID. Differentiation bit needs to be set to show the difference between MOCN ID or key domain ID.MSK ID remains as before 4 bytes. 2) Key domain ID can be set to Zero or default value. MSK ID can remain as before with 4 bytes. MOCN ID can be introduced, and range of values are defined. For many such MOCN use cases, where different broadcast cases of RAN sharing will be assigned a MOCN ID value. MSK ID remains as before 4 bytes. 3) Key domain ID can be set to
description: A Multi-Operator Core Network (MOCN) is a network configuration where multiple Public Land Mobile Networks (PLMNs) share the same core network infrastructure. This enables efficient use of resources and improved services for users. In 5G, MOCN is crucial for broadcast use cases, requiring common mechanisms for key derivation across different PLMNs.
explanation: The text describes a 'Multi-Operator Core Network' (MOCN) as a shared infrastructure used by multiple Public Land Mobile Networks (PLMNs). This definition aligns with the concept of a network, which is a system of interconnected nodes facilitating communication and data exchange.
