what happen after paging

When UE is in idle mode DRX and receive paging message, it will establish RRC connection, and when it become RRC-Connected, what happen next?
Does it change to connected mode DRX? or it will turn to RRC-Idle after receiving packet?

And I have another question
when a UE is in connected mode DRX, will it remain RRC-Connected when it turn to sleep mode(opportunity for DRX)?

When a UE is in idle mode DRX, if it receive a paging message, it will establish RRC connection and become RRC-Connected
question:
1.Will its DRX mode become connected when it become RRC-Connected?
2.Will it turn to RRC-Idle when it received packet and there's no other packet coming?
3.If a UE is in connected mode DRX, will it still remain RRC-Connected when it's in sleep mode(opportunity for DRX)?

Consider if eNB is sending DRX cycles to your UE and therefore you will be not listening to PDCCH. Now if MME sends paging messages of that UE, then how UE will be able to receive the paging message? After DRX cycles UE can start listening but MME might have stopped sending paging messages. How this is handled in LTE???

When we will construct a RRC paging message with multiple paging records?
In which scenario I need to construct a RRC paging message message with multiple paging records.Suppose we have 10 UEs in idle mode and DL data notification is comming for 5 UEs at the same time,then how mme will send S1AP paging message(i.e one by one for each UE or all the message at once).If ENB is receiving all the four S1AP paging message then how RRC has to process the S1AP paging messages and how it should construct the RRC paging message (i.e whether it should send one paging record for one pcch message or it should send multiple records in one PCCH message?if multiple records then how to send the UE_ids to MAC and RLC?).

PagingUE-Identity ::= CHOICE {
s-TMSI S-TMSI,
imsi IMSI,
...
}

As pagingUE identity should contain any one of these in paging message so how MME decides which one to send, though for security purpose MME prefers t-o send send S-TMSI but in which scenarion MME wil use imsi as paging ue identity.
