You asked: What is LTE HSS?

The Home Subscriber Server (HSS) is a key element of LTE and IMS core networks; it is a master user database that is stored in one single node. … Combined with an Authentication, Authorization, Accounting (AAA) server, the HSS ensures that an LTE network works with legacy or concurrent services.

What is the difference between HLR and HSS?

The HSS is a super HLR that combined legacy HLR and AuC functions together for CS and PS domains. In the IMS architecture, the HSS connects to application servers as well as the Call Session Control Function (CSCF) using the DIAMETER protocol.

What is HSS in 5g?

Abstract: Home Subscriber Server (HSS) is the main database of the current generation’s cellular communications systems. It contains subscriber-related information, such as the authentication information and the list of services to which each user is subscribed.

What is SGW and PGW in 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).

What is EPC in LTE?

Evolved Packet Core (EPC) is a framework for providing converged voice and data on a 4G Long-Term Evolution (LTE) network. … Evolved Packet Core unifies voice and data on an Internet Protocol (IP ) service architecture and voice is treated as just another IP application.

What is HLR?

HLR (Home Location Register) is a database that contains various information about all of the mobile subscribers of a mobile network such as the mobile numbers, services, whether the numbers have been ported to another network and similar information.

What is home subscriber server?

The Home Subscriber Server is the master user database that supports the IMS network entities that handle the calls/sessions. It contains user profiles, performs authentication and authorization of the user, and can provide information about the physical location of user. It’s similar to the GSM Home Location Register.

What is F1 interface in 5G?

5G NR F1 Interface

-F1 interface defines inter-connection of a gNB-CU and a gNB-DU supplied by different manufacturers. -It supports control plane and user plane separation. -It separates Radio Network Layer and Transport Network Layer.

What is AMF in 5G?

With the functionality of the 4G Mobility Management Entity (MME) now decomposed, the 5G Core Access and Mobility Management Function (AMF) receives all connection and session related information from the User Equipment (UE) (N1/N2) but is responsible only for handling connection and mobility management tasks.

What is NRF in 5G?

Oracle Communications Cloud Native Core, Network Repository Function (NRF) works as a centralized repository for all the 5G network functions (NFs) in the operator’s network. The NRF allows 5G NFs to register and discover each other via a standards-based API.

What are the goals of LTE?

The main goal of LTE is to provide a high data rate, low latency and packet optimized radioaccess technology supporting flexible bandwidth deployments. Same time its network architecture has been designed with the goal to support packet-switched traffic with seamless mobility and great quality of service.

What is the function of MME in LTE?

MME (Mobility Management Entity):The MME is an important controller node in the LTE network. It is responsible for: Idle mode UE (User Equipment) tracking. Paging procedure such as re-transmissions.

What is the function of PCRF in LTE?

The PCRF provides the QoS authorization (QoS class identifier [QCI] and bit rates) that decides how a certain data flow will be treated in the PCEF and ensures that this is in accordance with the user’s subscription profile. PCRF provides service management and control of the 4G service.

Is LTE better than 4G LTE?

LTE-A is a more robust version. They still don’t reach true 4G speeds. It is possible to get closer to the 4G standards with newer technology, but most of the time, you are probably not going to see a huge difference. The LTE network needs to be upgraded to handle higher 4G speeds as well.

How does handover work in LTE?

Handover procedures are a key function of LTE eNBs. They are intended to reduce interruption time compared to the circuit-switched handover process in 2G networks. … Handover within an E-UTRAN. The procedure for when a UE is leaving a cell managed by the eNB and entering a cell managed by a second eNB.
