ABSTRACT:
Reset of one or more state variables of a User Equipment (UE) RLC layer is carried out by signaling reset from a radio link control layer of a source radio network controller (RNC) to a radio link control layer of the UE during a seamless control relocation procedure in which a possible loss of synchronization and consequent disruption in communication between the UE and a target RNC is avoided.
