As per the specification, counter check procedure is used by eNodeB towards UE to cross check the values of count (uplink direction count and downlink direction count) for an established DRB against the value it has for that DRB. It is done just to check the presence of an intruder who can introduce the packets between UE and eNodeB.
However I have not worked in this procedure and has limited understanding.

It may be an easy question but still I have some doubt.
How RRC Connection setup procedure gets impacted with the presence of "S-TMSI" as an UE-Identity within the RRC Connection Request message ?
Note: RRC Connection request message can carry either 5 bytes long (S-TMSI) or 5 bytes long random value.
