What is LTE SGW?
SGW (Serving Gateway):The main function of the Serving Gateway is routing and forwarding of user data packets. It is also responsible for inter-eNB handovers in the U-plane and provides mobility between LTE and other types of networks, such as between 2G/3G and P-GW.
What is MME and SGW?
MME stands for Mobility Management Entity, PGW stands for PDN gateway and SGW stands for Serving Gateway. The figure depicts LTE EPS architecture. In the figure, UE refers to User Equipment. It is the mobile phone device used to access the LTE network.
What is the function of SGW?
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 P Gateway?
In a mobile network, a major function of the Packet Data Network Gateway (P-GW) is to allocate IP addresses to the user equipment during default bearer setup. EPS Bearer—This is the interface to the user equipment associated with the P-GW. It is a tunnel and used for IP address allocation and other purposes.
Why is it called eNodeB?
E-UTRAN Node B, also known as Evolved Node B (abbreviated as eNodeB or eNB), is the element in E-UTRA of LTE that is the evolution of the element Node B in UTRA of UMTS. Traditionally, a Node B has minimum functionality, and is controlled by a Radio Network Controller (RNC).
What is LTE MME?
The mobility management entity (MME), which presents a key control node for the LTE access network, manages UE access network and mobility, as well as establishing the bearer path for UE’s. The MME also controls mobility between LTE and 2G/3G access networks.
What does SGW stand for in LTE network?
SGW (Serving Gateway) The SGW node handles the user data traffic, but isn’ t responsible for the signaling data used. It transports IP data from UE’s to the LTE Core Network. The SGW also routes incoming and outgoing IP packets for better system collaboration and serves as an anchor for the UE when it moves from one eNodeB to another.
What is the function of PGW in LTE?
LTE PGW | PDN Gateway | Packet Data Network Gateway Following are the functions of PGW (Packet Data Network Gateway): • It provides access to external PDNs (Packet Data Networks). • If UE has multiple data sessions to multiple PDNs.
What does Mme, PGW, and SGW stand for?
MME stands for Mobility Management Entity, PGW stands for PDN gateway and SGW stands for Serving Gateway. The figure depicts LTE EPS architecture. In the figure, UE refers to User Equipment. It is the mobile phone device used to access the LTE network. It can also be tablet, USB dongle which is LTE compliant to have access to 4G LTE internet.
What are the functions of a SGW router?
• SGW functions as IP router with GTP support and charging functionality. • It provides access to external PDNs (Packet Data Networks). • If UE has multiple data sessions to multiple PDNs. In this case, UE can be connected with multiple PGWs but it will still be served by only one SGW.
