name: RNC
full_form: Radio Network Controller
context: Setting up and configuring RNCs in exposed locations shall be authenticated and authorized so that attackers shall not be able to modify the settings and software configurations of the RNCs in exposed locations via local or remote access. 1. The support of security associations is required between the 3G core network and the RNC in an exposed location and between adjacent RNCs in exposed locations. These security association establishments shall be mutually authenticated and used for user and control plane communication between the entities. The security associations shall be realized according to Annex I.3 of the present document. 2. Communication between the O&M systems and the RNC in an exposed location shall be confidentiality, integrity and replay protected from unauthorized parties. The support of security associations is required between the RNC in an exposed location and an entity in the 3G core network or in an O&M domain trusted by the operator. These security association establishments shall be mutually authenticated. 3. The RNC in an exposed location shall ensure that software/data change attempts are authorized. 4. The RNC in an exposed location shall use authorized data/software. 5. Sensitive parts of the boot-up process shall be executed with the help of the secure environment. 6. Confidentiality of software transfer towards the RNC in an exposed location shall be ensured. 7. Integrity protection of software transfer towards the RNC in an exposed location shall be ensured.
description: The Radio Network Controller (RNC) is a critical network element within the Universal Mobile Telecommunications System (UMTS) architecture, responsible for controlling and managing multiple Node Bs (base stations). It plays a pivotal role in handling radio resource management, mobility management, and packet scheduling. The RNC is also involved in the security aspects of the network, ensuring secure communication between the core network and the RNC, as well as between adjacent RNCs. This includes establishing mutually authenticated security associations for user and control plane communication, protecting against unauthorized access, and ensuring confidentiality, integrity, and replay protection of data.
explanation: RNC is classified as a Network Function because it serves as a key component in managing radio resources, mobility, and packet scheduling within the UMTS architecture. Its role in establishing secure associations and protecting network communication aligns with the security requirements outlined in the provided context, emphasizing its importance as a network function.
