Dec 29, 2022 · The 5G Session Management Function (SMF) is a critical 5G core component that performs a fundamental role in the 5G Service-Based Architecture (SBA).

Oct 20, 2018 · SMF — Session Management Function. The SMF performs the session management functions that are handled by the 4G MME, SGW-C, and PGW-C. Allocates IP addresses to UEs

Explore the functions of 5G NR network nodes, including AMF, UPF, SMF, PCF, UDM, DN, AUSF, and AF, as defined in 3GPP specifications.

Jan 25, 2023 · The Session Management Function (SMF) plays a critical role in managing and controlling sessions in the 5G network. It is responsible for setting up and managing sessions according to the network policy, and providing services to consumer network functions to control PDU session events.

Sep 11, 2022 · SMF is a Control Plane(CP) function that manages the session-related context with the UPF. It creates, updates, and removes sessions. It also allocates the IP addresses to each PDU session.

Apr 6, 2023 · In 5G, SMF stands for “Session Management Function.” It is a core network element responsible for managing the sessions between user devices and the network. Section 6.2.2 of 3GPP’s Technical Specification 23.501 provides a detailed description of …

Sep 23, 2020 · After a PDU session is created on the PGW-C+SMF with E-UTRAN, Mobility Management Entity (MME) and Serving Gateway (S-GW), the UE can hand over E-UTRAN to 5G New Radio (NR) and vice-versa. The SMF currently …

Jan 26, 2023 · Another major difference in 5G’s control plane is the structure, which includes different functional separation of Access and Mobility Functions (AMF) and Session Management Functions (SMF). This allows for more granular control of network functions, and enables new services and use cases.

In the 5G architecture, SMF is responsible for session management with individual functions being supported on a per session basis. SMF allocates IP addresses to UEs, and selects and controls the UPF for data transfer.

In this article, we will put our focus on Service-Based Architecture (SBA) which is the recommended and programmable architecture design for the interconnection of 5G network functions in the Core and exposure of network capabilities & resources via Service message bus.
