What is the difference between 3GPP and non-3GPP?
3GPP specifications define how the interworking is achieved between an E-UTRAN (LTE and LTE-Advanced), GERAN (radio access network of GSM/GPRS) and UTRAN (radio access network of UMTS-based technologies WCDMA and HSPA). Non-3GPP means that these accesses were not specified in the 3GPP.
What is untrusted in non-3GPP?
Untrusted WLANs include public hotspots, home Wi-Fi, corporate Wi-Fi etc. that are not controlled by the mobile network operator.
What is IMS and EPC?
First of all there is the Evolved Packet Core (EPC) and then there is the IP Multimedia Sub-system (IMS), as shown in Figure 3.15. All user data goes through EPC and the data related to the operator IMS services (such Voice over LTE) goes also via IMS while traffic to the normal internet does not.
Is WIFI a 3GPP?
Ericsson Wi-Fi Mobility Gateway complies with 3GPP Rel 14 specification, implementing the evolved Packet Data Gateway (ePDG) and Trusted Wi-Fi Gateway (TWAG) network functions.
Which technique is used for LTE interworking with CDMA ie non 3GPP networks?
Why eHRPD? A focus of 3GPP standardization has been the evolution and interworking among 3G UMTS networks, to 4G LTE networks, to non-3GPP access networks all using a single packet core called Enhanced Packet Core or EPC.
What is EPC in telecom?
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 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 companies are in 3GPP?
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 VoLTE and IMS?
VoLTE stands for Voice over Long-term Evolution. Utilizing the IMS (IP Multimedia Subsystem) technology, it is a specific type of VoIP service designed into the LTE standard, which enables users to make voice calls while simultaneously using data network LTE.
What is 3GPP access and non 3GPP access?
Overview of 3GPP options for Wi-Fi access. The 3GPP standard defines two types of access; trusted and untrusted non-3GPP access. Non-3GPP access includes access from for instance Wi-Fi, WiMAX, fixed and CDMA networks.
Which is an example of a non 3GPP network?
5G system supports access to 3GPP as well as Non-3GPP networks. An example of a Non-3GPP network is WLAN which can be either trusted or non-trusted. It uses a Non-3GPP Interworking Function (N3IWF) to establish connectivity to the 5G core network.
What is the role of untrusted non 3GPP access?
Untrusted non-3GPP accesses interwork with the EPC via a network entity called the ePDG (for Evolved Packet Data Gateway). The main role of the ePDG is to provide security mechanisms such as IPsec tunnelling of connections with the UE over an untrusted non-3GPP access.
Who is responsible for the management of the 3GPP network?
The 3GPP SA WG5 is responsible for the management and charging of the 3GPP-defined network and services. SA WG5 provides the 3GPP wide management view in coordination with the Core Network (CN) and the Radio Access Network (RAN).
What does EPs mean in terms of non 3GPP?
The EPS also allows non-3GPP technologies to interconnect the UE and the EPC. 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”:
