name: RCAF
full_form: Radio Capability Application Function
context: Legend: Nq-AP: This application layer protocol supports the IMSI and APN retrieval procedure between the RCAF and the MME. Stream Control Transmission Protocol (SCTP): This protocol transfers signalling messages. SCTP is defined in RFC 4960 [35]. Figure 5.1.1.13-1: Control Plane for Nq interface
description: The Radio Capability Application Function (RCAF) is a network function that plays a crucial role in the control plane of the Nq interface, specifically involved in the retrieval procedure of IMSI and APN between the RCAF and the MME. It utilizes the Stream Control Transmission Protocol (SCTP) for transferring signaling messages, adhering to the standards defined in RFC 4960.
explanation: RCAF is classified as a Network Function because it participates actively in managing radio capabilities and interacts with other network functions like the MME through standardized protocols, fitting within the broader context of 3GPP's architectural framework for efficient control plane operations.
