What is 3GPP access and non-3GPP access?

What is 3GPP access and non-3GPP access?

Non-3GPP means that these accesses were not specified in the 3GPP. These technologies includes e.g. WiMAX, cdma2000®, WLAN or fixed networks. Non-3GPP accesses can be split into two categories: the “trusted” ones and the “untrusted”: Trusted non-3GPP accesses can interact directly with the EPC.

What are 3GPP standards?

The 3rd Generation Partnership Project (3GPP) is an umbrella term for a number of standards organizations which develop protocols for mobile telecommunications. Its best known work is the development and maintenance of: GSM and related 2G and 2.5G standards, including GPRS and EDGE.

What is trusted non 3GPP?

Trusted non-3GPP Wi-Fi access was first introduced with the LTE standard in 3GPP Release 8 (2008). Trusted access is often assumed to be an operator-built Wi-Fi access with encryption in the Wi-Fi radio access network (RAN) and a secure authentication method.

Is WIFI a 3GPP?

A WLAN Access Network (WLAN AN) recognizes and processes 3GPP WLAN connection requests for the 3GPP network. It provides the wireless IP connectivity to the WLAN UE to be authenticated and authorized by the 3GPP AAA server in the 3GPP network.

What is the purpose of 3GPP?

The 3rd Generation Partnership Project (3GPP) is a collaborative project between a group of telecommunications associations with the initial goal of developing globally applicable specifications for third-generation (3G) mobile systems.

What is the meaning of 3GPP?

3rd Generation Partnership Project
The 3rd Generation Partnership Project (3GPP) unites seven telecommunications standard development organizations (ARIB, ATIS, CCSA, ETSI, TSDSI, TTA, TTC), known as “Organizational Partners” and provides their members with a stable environment to produce the Reports and Specifications that define 3GPP technologies.

What is LTE interface?

Within an LTE network, LTE Interfaces connect the various components to or within the core. Interfaces allow the MME, SGW and PGW to cooperate with other network elements (e.g. HSS or PCRF). Each one of them is built in a standard way described by 3GPP.org.

What is SGd interface?

The SGd interface enables the transfer of short messages between the MME and the SMSC using Diameter protocol. The Short Message Control Protocol (SM-CP) and Short Message Relay Protocol (SM-RP) are traditional SMS protocols between MSC/VLR and UE.

What is LTE EPC?

Evolved Packet Core (EPC) is a framework for providing converged voice and data on a 4G Long-Term Evolution (LTE) network. This allows operators to deploy and operate one packet network for 2G, 3G, WLAN, WiMax, LTE and fixed access (Ethernet, DSL, cable and fiber).

What are the different types of non-3GPP access networks?

In this Release of the specification, the following types of non-3GPP access networks are defined: – Wireline access networks. The architecture to support Untrusted and Trusted non-3GPP access networks is defined in clause 4.2.8.2. The architecture to support Wireline access networks is defined in clause 4.2.8.2.4 and in TS 23.316 [84].

What is the architecture to support 5G wireline access networks?

The architecture to support Wireline access networks is defined in clause 4.2.8.2.4 and in TS 23.316 [84]. The 5G Core Network supports connectivity of UEs via non-3GPP access networks, e.g. WLAN access networks.

What is the difference between untrusted and trusted non-3GPP networks?

An untrusted non-3GPP access network shall be connected to the 5G Core Network via a Non-3GPP InterWorking Function (N3IWF), whereas a trusted non-3GPP access network shall be connected to the 5G Core Network via a Trusted Non-3GPP Gateway Function (TNGF).
