PDCP Operation for Dual Connection

摘要

An apparatus of a communication network detects that a modification of a radio resource control connection for a user equipment is required. The apparatus decides, based on the detected modification requirement, if a re-establishment of a packet data convergence protocol is required for a first radio bearer and/or a second radio bearer, and indicates, in a radio resource control reconfiguration message, the first radio bearer and/or the second radio bearer for which re-establishment of the packet data convergence protocol is required. The user equipment detects, from the radio resource control reconfiguration message, that a modification of a radio resource control connection between the user equipment and the communication network is required, and re-establishes the packet data convergence protocol for the first radio bearer and/or the second radio bearer in accordance with the indication set in the radio resource control reconfiguration message.
