In principle S5 and S8 is the same interface, the difference being that S8 is used when roaming between different operators while S5 is network internal. The S5/S8 interface is used within the Evolved Packet Core (EPC) for LTE.
Which interface is based on AAA protocol in LTE?
Diameter is a next-generation industry-standard protocol used to exchange authentication, authorization and accounting (AAA) information in Long-Term Evolution (LTE) and IP Multimedia Systems (IMS) networks.
What is the function of LTE?
LTE (Long Term Evolution) is the project name given to development of a high performance air interface for cellular mobile communication systems. It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks.
What is 5G short for?
What does 5G stand for? 5G is the fifth generation of cellular networks, and it is expected to be one of the fastest wireless technologies ever created. (This is not to be confused with the 5G that you may see on your Wi-Fi router, which is referring to 5 GHz frequency for your internet network.)
What is Gx interface?
The Gx interface connects the PCRF with policy enforcement points. These are found in the packet core of 3G and 4G networks. The serving GPRS support node (SGSN), gateway GPRS support node (GGSN), and PDN Gateway are all considered as enforcement points, supported by the Gx interface.
What is S6b interface used for?
The S6b interface shall enable the authentication and authorization between the UE and the 3GPP AAA Server/Proxy for DSMIPv6. When an UE performs the DSMIPv6 initial attach, it runs an IKEv2 exchange with the PDN GW as specified in 3GPP TS 24.303 . In this exchange EAP AKA is used for UE authentication over IKEv2.
What is S GW LTE?
Cisco Serving Gateway (SGW) is a critical network function for the 4G mobile core network, known as the evolved packet core (EPC). The SGW resides in the user plane where it forwards and routes packets to and from the eNodeB and packet data network gateway (PGW).
How does network sharing works in LTE?
3GPP network sharing architecture allows different core network operators to connect to a shared radio access network. The operators do not only share the radio network elements, but may also share the radio resources themselves.
