What is the difference between 3GPP and non 3GPP?

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 the components of EPC?

The three core elements of the EPC are the Mobility Management Entity (MME), Serving Gateway (SGW), and Packet Data Network Gateway (PGW).

What is MME in EPC?

An MME is a critical network function, which deals with the EPC control plane. Its role is to manage sessions, authentication, paging, mobility, bearers and roaming. It manages an eNB and an S-GW through the S1-MME and S11 interfaces respectively, and communicates with HSS through the S6 interface.

What is evolved packet core?

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 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.

What is 3GPP and non-3GPP access?

The current 3GPP specification specifies support for only Wireless LAN (Wi-Fi) Access Network (WLAN) as the non-3GPP access network; hence, the same is considered for the untrusted non-3GPP access network in this paper. Need. Untrusted WLANs include public hotspots, home Wi-Fi, corporate Wi-Fi etc.

What is trusted non 3GPP?

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.

Which is the reference point between utran and serving GW?

S1-U:- Reference point between E-UTRAN and Serving GW for the per bearer user plane tunnelling and inter eNodeB path switching during handover. S3:- It enables user and bearer information exchange for inter 3GPP access network mobility in idle and/or active state.

What is GGSN PGW?

PGW/GGSN, developed in Sweden by Leissner, is a standardized packet core component that operators and MVNOs need between the GSM, UMTS, LTE and 5G NR network and the Internet. This suite of flexible functionality empowers MVNO and MVNEs to stay ahead of competition and gives low TCO (Total Cost of Ownership).
