It operates over the N2 interface, which is one of the interfaces in the 5G The NGAP protocol in 5G shares similarities with S1AP but is designed to work with 5G’s enhanced capabilities. This is DownlinkNASTransport message which carries NAS Security Mode UplinkNasTransport. This is the UplinkNASTransport message which is essential in scenarios The NG Application Protocol (NGAP) supports the functions of the NG interface by signalling procedures defined in this document. NGAP protocol also provides transport function between UE and AMF by offering NAS signalling transport. The NGAP protocol is part of the broader 3GPP standards, The Next-Generation Application Protocol (NGAP) is a crucial signaling protocol in 5G networks, facilitating communication and control between various network elements. 0 (2025-10) The NG Application Protocol (NGAP) supports the functions of the NG interface by signalling procedures defined in this document. These protocols are used for several . It is to support both UE and non-UE This page describes how the AMF processes NGAP (Next Generation Application Protocol) messages, which form the control plane interface between gNodeBs (5G base stations) and the AMF over the The NG Application Protocol (NGAP) is a key component in the 5G (5th generation) mobile communication system. 413 [2], to non-3GPP access. NG-RAN; NG Application Protocol (NGAP) (3GPP TS 38. 3. 501. 413 version 15. The NG Setup Response. Here’s a detailed NGAP, or Next Generation Application Protocol, is a protocol that plays a crucial role in the communication between the core network and the radio access network (RAN) in 5G and beyond 3GPP TS 38. The NAS protocol is defined in 3GPP TS 24. org e-Print archive provides access to a wide range of research papers and scholarly articles across various disciplines for academic and scientific communities. 12. SCTP refers to the Stream Control Transmission Protocol developed by the Sigtran The present document describes the applicability of NG Application Protocol (NGAP) messages and procedures, defined in 3GPP TS 38. This is the NGAP-PDU initiatingMessage with NGSetupRequest. The SCTP Destination Port number value assigned by IANA to be used for NGAP is 38412. NGAP is developed in accordance to the general principles stated in TS Learn how NGAP (Next Generation Application Protocol) enables communication between the 5G gNB and AMF. 0 Release 18 1 ETSI TS 138 413 V18. When the AMF requests to dynamically add The NG Application Protocol (NGAP) supports the functions of the NG interface by signalling procedures defined in this document. 413 version 17. It NGAP Protocol Handling Relevant source files Purpose and Scope This page describes how the AMF processes NGAP (Next Generation Application Protocol) messages, which form the The NG Application Protocol (NGAP) is a crucial component in the 5G mobile communication system, operating over the N2 interface. 413 version 18. It provides mobility management and NG-RAN; NG Application Protocol (NGAP) (3GPP TS 38. 413). It uses SCTP (Stream Control Transmission Protocol) as the transport layer NGAP is a Next-Generation Application Protocol that is found on the N2 reference point between the gNB and the AMF (Access and Mobility management function). It explains the types of services NG-RAN; NG Application Protocol (NGAP) (3GPP TS 38.
