RL (Radio Link)
represents
the physical connection between the UE and Node B.
Each RL is defined by its RF frequency, channelization code and scrambling code.

various types of connections that the UE will have with the network:
1. RL
2. RB
3. RAB
4. SRB
5. PDP
6. RRC connection
RL (UE-Node B)
RB (UE-Node B-RNC)
RAB (UE-Node B-RNC-SGSN)
PDP context (UE-Node B-RNC-SGSN-GGSN)
