What is 3GPP2 program?

The 3rd Generation Partnership Project 2 (3GPP2) is a collaboration between telecommunications associations to make a globally applicable third generation (3G) mobile phone system specification within the scope of the ITU’s IMT-2000 project.

What is radio access technology used for?

A Radio Access Technology or (RAT) is the underlying physical connection method for a radio based communication network. Many modern mobile phones support several RATs in one device such as Bluetooth, Wi-Fi, and GSM, UMTS, LTE or 5G NR.

What is RAN technology?

News & insights Glossary. A radio access network (RAN) connects individual devices to other parts of a network through radio connections. It is a major component of modern telecommunications with different generations of mobile networking evolving from 1G through 5G.

What are types of RAN?

The different types of RANs reflect advancements in networking technology. These types of RANs include GSM RAN (GRAN), GSM EDGE RAN (GERAN), UMTS RAN (UTRAN), and Evolved UTRAN (E-UTRAN).

Which new UE state was introduced in 5G?

Appart form RRC connected and RRC IDLE state, 5G NR has introduced a new RRC state names as RRC Inactive state. When UE is power up it is in Disconnected mode/Idle mode, It can move RRC connected with initial attach or with connection establishment.

What is NSA mode?

NSA (Non-Standalone Access) and SA (Standalone Access) are the two 5G network modes. NSA relies on the 4G network facilities to provide more speed and higher data bandwidth. A 5G-enabled smartphone will connect to a 5G or 4G network depending on conditions.

What is the 3GPP project?

The project covers cellular telecommunications technologies, including radio access, core network and service capabilities, which provide a complete system description for mobile telecommunications. The 3GPP specifications also provide hooks for non-radio access to the core network,and for interworking with non-3GPP networks.

How are 3GPP2’s technical specifications produced?

The work of producing 3GPP2’s specifications resides in the Project’s two Technical Specification Groups (TSGs) comprised of representatives from the Project’s Individual Member companies. The TSGs are: Each TSG meets approximately four times per year to produce technical specifications and reports.

What is progressive 3GPP radio access technology?

Each progressive 3GPP radio access technology aims to reduce complexity and avoid fragmentation of technologies on offer. GSM networks used circuit-switch telephony initially, with packet-switching added with GPRS.

How is 3GPP standardization work done?

3GPP standardization work is contribution-driven. Companies (“individual members”) participate through their membership to a 3GPP Organizational Partner. As of December 2020, 3GPP is composed of 719 individual members. Specification work is done at WG and at TSG level:
