What are the main network elements and architectures of TD-LTE EPC?
EPC mainly includes three network elements: Mobility Management Entity (MME), Service Gateway (S-GM) and PDN Gateway (P-GW).
MME is responsible for NAS security, idle mode processing and EPS bearer control, and is mainly responsible for signaling interaction between UE and core network.
S-GM is responsible for the transmission of user IP packets, which is based on other 3GPP technologies, such as GPRS and UMTS interactive as external interfaces.
P-GW is responsible for user IP address allocation and service QoS guarantee, and carries out traffic-based billing according to PCRF rules. It can be used as an external interface to interoperate with non-3GPP technologies such as cdma2000 and WiMAX.
