LTE Network Elements
•Evolved Node B (eNB) Supports air interface Provides radio resource management
functions
• Serving Gateway (SGW) Provides Mobility Responsible for Routing and Forwarding

LTE Network Elements (Continued)•Packet Data Network Gateway (PDN GW)
Provides connectivity to Internet Provides QoS and mobility between 3G and
non-3G networks•Mobility Management Entity (MME)
Manages mobility and provides security Operates in control plane and provides
authentication
