Best answer

"Always on connectivity" is true since the IP address allocated to UE still hold by the network and UE even after the release of radio connection.

when UE is idle only S5 connection will be there and P-GW is connected to the default PDN. This is how the IP address is held by the network. Am I right? Correct me if I am wrong.

Yes, your understanding is correct. S5 and S11 both the interface tunnels will be exist even after UE goes to the IDLE mode.

When UE is in the Connected State, How UE could use DRX configuration which is intended to use in IDLE state?

During my study about the measurement and ANR, I have the question. Please help to let me get the proper answer.
[ Condition]
1. UE is in the connected state.
2. UE measures one PCI and reports it to eNB but it does not belong to NRT(Neighbor Relation Table) in eNB.
3. eNB sends rrcConnectionReconfigurationMessage to read CGI for that PCI.
4. UE should read MIB/SIB1 to report CGI info to eNB.

In Step 4), In some materials on the web, UE should use IDLE periods to get SIB1, which is configured as DRX config in rrcConectionReconfigurationMesage. Because Measurement Gap is too short to read MIB/SIB1 and it's only for the measurement purpose.

As my basic understanding, DRX configuration is to improve the battery life in idle mode.
