The LTE S1-MME interface is responsible for delivering signaling protocols between the eNodeB and the MME. S1-MME interface consists of a Stream Control Transmission Protocol (SCTP) over IP and supports multiple UEs through a single SCTP association.

S1-MME interface: Used as a control application protocol between the E-UTRAN (eNodeB or LTE Base Station) and MME. It handles control plane signaling for mobility management, session management, and bearer management between the user equipment (UE) and the core network.

LTE Interfaces includes (S11, S5, S8, SGi, S1-U). S11 Interface connects between the MME and the SGW, and it uses GTP-C protocol. S5/S8 interface connects between the SGW and the PGW.

The S1-MME interface is a critical control plane interface in LTE networks, connecting the evolved Universal Terrestrial Radio Access Network to the Mobility Management Entity (MME). This interface ensures effective communication and coordination …

Jan 18, 2024 · The S1-MME (S1 Mobility Management Entity) interface is a crucial component within the Long-Term Evolution (LTE) network architecture, responsible for facilitating communication and signaling exchanges between two key entities: the Evolved NodeB (eNodeB) and the Mobility Management Entity (MME).

Jun 22, 2023 · The S1-MME (S1 for the control plane) is a protocol used in the Long-Term Evolution (LTE) and 5G networks for communication between the Evolved Node B (eNodeB) and the Mobility Management Entity (MME).

The S1 control plane interface (S1-MME) uses the SCTP/IP stack to ensure reliable delivery of signaling messages. SCTP includes advanced features like multistreaming and multihoming, which enhance reliability and efficiency.

The S1 interface connects the eNB to the EPC. It can be split into control-plane (S1-MME) and user-plane (S1-U). The S1-MME is a signaling interface which supports a set of functions and procedures between the eNB and the MME. All S1-MME signaling procedures belong to four main groups: (1) bearer-level procedures, corresponding to all ...

Jan 8, 2012 · S1-AP (S1 Application Protocol): Application Layer Protocol between the eNodeB and the MME. SCTP: This protocol guarantees delivery of signalling messages between MME and eNodeB (S1). SCTP is defined in RFC 4960.

Dec 6, 2013 · The handover procedure for Intra-LTE handover using the S1 interface is very similar to that of Intra-LTE Handover Using the X2 Interface, except the involvement of the MME in relaying the handover signaling between the S-eNB and T …
