S1-MME S6a HSS SGSN MME UTRAN GERAN 4th ETSI Security Workshop - Sophia-Antipolis, 13-14 January 2009 10 RRC signalling between UE and E-UTRAN NAS signalling between UE and MME S1 interface signalling protection is not UE-specific optional to use S10 UE LTE-Uu E-UTRAN S11 Serving S5 Gateway S1-U S4. Industry organizations such as the 3GPP, ETSI, IETF, ITU, GSMA, WBA and several others have gone to great length in specifying architectural reference models, naming conventions and interface functionality. 3 The Structure of 3GPP 14. White Paper Mobile Edge Computing Use Cases & Deployment Options Prepared by Gabriel Brown Senior Analyst, Heavy Reading www. From protocol perspective, the same S1AP and X2AP protocols are used in HeNBs as well as macro eNodeBs. Towards Flexible Network and AI Dr. The eNBs are connected by means of the S1 interface to the evolved packet core (EPC), more specifically to the serving gateway (S-GW) over the S1-U interface and to the mobility management entity over the S1-MME interface. In a laboratory it can be paired with the LTE LabKit for a full LTE/GSM network. 2 References. It covers functions and locations of these 5G NR interfaces used between 5G RAN and 5GC. 246: Transparent end-to-end Packet-switched Streaming Service (PSS); 3GPP SMIL language profile: 30: TS 26. Interface Protocols and Specifications NE1 NE2 RAN – Core S1 S1-MME (S1-AP): 3GPP TS 36. The inter NB interface between one LTE/eLTE eNB and one gNB. Sec-tion IV reviews the related work. Narrowband Internet of Things Whitepaper As part of Release 13, 3GPP has specified a new radio interface, the Narrowband Internet of Things (NB-IoT). Private packet data network 3. Objectives Upon completion of this chapter, you should be able to Describe the SGSN-to-GGSN interface. The S5/8 interface provides user planes tunneling and tunnel management between SGW and PGW. Handover between LTE and 3G Radio Access Technologies: Test measurement challenges and field environment test planning School of Electrical Engineering Master‟s thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Technology in Espoo, 30. 3GPP TS 25. 3GPP work on the Evolution of the 3G Mobile System started with the RAN Evolution Work Shop, 2 - 3 November 2004 in Toronto, Canada. Jyri Hämäläinen Instructor:. S1-flex in 3GPP LTE standard) or multioperator RAN Sharing reason. Does 3GPP need to support all remaining 11 architecture options ? Is there a phasing possible / desirable ? How to ensure forward compatibility in order to avoid global fragmentation, especially considering roaming ? 5G architecture options | RAN/SA meeting, June 2016 RP-161266 15. S1AP is developed in accordance to the general principles stated in TS 36. 281 General Packet Radio System (GPRS) Tunneling Protocol User Plane (GTPv1-U) è 3GPP TR 23. A PDN is an internal or external IP domain of the operator that a UE wants to communicate with, and provides the UE with services such as the Internet or IP Multimedia Subsystem (IMS). The EPC Signalling course describes the Evolved Packet Core (EPC) as standardized by 3GPP in technical specifications. • Alternative 3C: Small cell connected to macro eNodeB via Xn-interface. eRAN S1-flex Feature Parameter Description: This document describes LOFD-001018 S1-flex, including its technical principles, related features, network impact, and engineering guidelines. 274 S4 S-GW Rel. During this time all relevant IEs are checked to be in place to make the operation of all identified interfaces smooth. 3af)3 Networking Protocols IPv4/IPv6, VLAN, IPSec Max Power Consumption 13W EPC Support Standard 3GPP S1 Interface SAS Support WINN Forum TS1. This enables connectivity between S-CSCF and TAS (Telephony Application Server). S1 MME, S1-U, S3, S4, S5, S6a, Gx, S11, SGi etc. BBB for the detailed explanation". 3 The Structure of 3GPP 14. LTE S1AP View of an Inter-MME S1 Handover Examine the S1AP messages involved in an S1 Handover at full message level detail. The first NB-IoT specification provided the underlying air interface standard for an ultra-low complexity NB1 device class with a long battery life. 41x series of technical specifications that define the S1. - to the MME by S1 control-plane part, S1-c. To provide flexibility to the networks, N26 is optional. An S1 handover is a fallback for scenarios where X2 interface is not available. eNBsare interconnected with each other by X2 interface eNBsare connected by means of S1 interface to the EPC S1 interface supports a many-to-many relation between MMEs/S-GW and eNBs 18 3GPP TS 36. Radio Resource Control 3G TS 25. Core part: Enhanced Inter-Cell Interference Control (ICIC) for non-Carrier Aggregation (CA) based deployments of heterogeneous networks for LTE. As mentioned in 3GPP TS 23501, sec 5. 3 S1 Interface 177. On the other over trusted and/or untrusted non-3GPP Access hand, the S1-U takes care of delivering user data between and/or 3GPP access. u can get it from the 3gpp site. Use our REST Dictionary to assist in your 4G and 5G core network testing or RESTful interface development. 414 Evolved Universal Terrestrial Radio Access Network Terminal logical test interface;. 501 – 5G Architecture EPC and eNodeB VNF are Open-Air Interface projects. The S1 Application Protocol (S1AP) supports the functions of S1 interface by signalling procedures defined in this document.
