What is 3GPP architecture?

3GPP began work in 2016 on defining 5G global standards for a new radio access technology — 5G NR (New Radio) — and a next-generation network architecture — 5G NextGen — to address these requirements. In parallel, 4G LTE continues to evolve as it will play an essential role in next-generation 5G networks.

What is 3GPP spec?

The term “3GPP specification” covers all GSM (including GPRS and EDGE), W-CDMA (including HSPA), LTE (including LTE-Advanced and LTE-Advanced Pro) and 5G specifications. Revised versions of many of these specifications are produced up to four times a year following the quarterly TSG plenary meetings.

What is the HSS in 5G?

Abstract: Home Subscriber Server (HSS) is the main database of the current generation’s cellular communications systems. It contains subscriber-related information, such as the authentication information and the list of services to which each user is subscribed.

What is AMF in 5G?

With the functionality of the 4G Mobility Management Entity (MME) now decomposed, the 5G Core Access and Mobility Management Function (AMF) receives all connection and session related information from the User Equipment (UE) (N1/N2) but is responsible only for handling connection and mobility management tasks.

What is af in 5G?

Application Function (AF) supports: application influence on traffic routing, accessing NEF, interaction with policy framework for policy control.

Who owns 5G towers?

A carrier, (i.e., Verizon, AT and T-Mobile) owns the active infrastructure to broadcast frequencies, including those of 5G. Whereas a tower company, (i.e., American Tower, Crown Castle, and SBA Communications) owns the passive infrastructure, to host this carrier equipment, including 5G antennas and radios.

Which is the latest version of 3GPP TS 29.163?

TISPAN; Endorsement of the SIP-ISUP Interworking between the IP Multimedia (IM) Core Network (CN) subsystem and Circuit Switched (CS) networks [3GPP TS 29.163 (Release 7), modified]

What does SS7 stand for in 3GPP specification?

Signalling System No. 7 (SS7) Security Gateway; Architecture, functional description and protocol details Study on IP Multimedia Subsystem (IMS) Proxy Call Session Control Function (P-CSCF) restoration procedures Study on General Packet Radio Service (GPRS) Tunnelling Protocol for Control plane (GTP-C) overload control mechanisms

What are the different types of 3GPP specification?

Service Enabler Architecture Layer for Verticals (SEAL); Application Programming Interface (API) specification; Stage 3 5G System; Home Subscriber Server (HSS) services for interworking with Unified Data Management (UDM); Stage 3 TISPAN; Interworking; Trunking Gateway Control Procedures for interworking between NGN and external CS networks

Which is the latest evolution of the 3GPP core network?

This article looks at the Evolved Packet Core (EPC), the core network of the LTE system, giving an overview of the architecture of the core network, describing some of its key elements. The EPC is the latest evolution of the 3GPP core network architecture. In GSM, the architecture relies on circuit-switching (CS).
