X2AP - X2 Application Protocol
The X2AP protocol is used to handle the UE mobility within E-UTRAN.


X2U- X2 User Plane -
Its X2 Userplane for handling data transfer in-between eNB’s

eNB or  eNodeB -

eNB interfaces with the mobile and is responsible for hosting and manging following interfaces.

Physical channels,
Medium Access Control (MAC),
Radio Link Control (RLC),
Packet Data Control Protocol (PDCP) layers.

SON is Self Optimizing Network.
A self optimizing function would increase network performance and quality by reacting to dynamic processes in the network. These operations minimizes the operational overhead by self- configuring and self -optimization.

Also manages many functions related to :-
Radio resource management,
Admission control,
Scheduling
Enforcement of negotiated UL QoS,
Cell information broadcast,
Ciphering /deciphering of user and control plane data,
Compression /decompression of DL/UL user plane packet
