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.Click to see full answer. Similarly, you may ask, what is a 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).Similarly, what is SAE GW? System Architecture Evolution (SAE) is the core network architecture of 3GPP’s LTE wireless communication standard. SAE is the evolution of the GPRS Core Network, with some differences: simplified architecture. all-IP Network (AIPN) support for higher throughput and lower latency radio access networks (RANs) Just so, what is the function of SGW in LTE? 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.How does Mme select SGW?SGW Selection. MME selects an available SGW to serve the UE, based typically on network topology and the location of the UE within the network, so that the best SGW is selected, e.g. to reduce the probability that the SGW is changed.
