Question: During the abortion of early security reactivation in an E-UTRA network, what action does the User Equipment (UE) take regarding its Radio Link Control (RLC) entities for both Signaling Radio Bearers (SRBs) and Data Radio Bearers (DRBs)?
Option 1: Re-establish RLC entities for all SRBs and DRBs.
Option 2: Suspend RLC entities for all SRBs but not for DRBs.
Option 3: Delete existing RLC entities without re-establishment for both SRBs and DRBs.
Option 4: Maintain current RLC entity configurations for both SRB and DRB.
Explanation: When aborting early security reactivation, the UE must reset certain security aspects but also ensure continuity of some basic communication channels. Re-establishing RLC entities for all SRBs (which carry signaling) and DRBs (which carry user data) ensures that while security is being reconfigured, the fundamental structure for future data and signal transmission is kept intact, ready for when security is properly reinstated. This action balances security reset with operational continuity.
