Abstract

A new RRC Connected (mobility) state is described in which a UE utilizes a temporary identifier to monitor a downlink control channel in accordance with a discontinuous reception cycle; and maintains the new connected state, the discontinuous reception cycle and the temporary identifier while the UE re-selects to a second/serving access node which lies within a same designated reselection area as a first/source access node. In various specific embodiments, the DRX cycle is maintained but re-aligned with a system frame number of the second access node; the temporary identifier is a CRNTI and the designated re-selection area is defined by all contiguous cells in which respective access nodes broadcast the CRNTI in system information; the UE re-selects to the second access node in the absence of control signaling; and the UE enters the new connected mobility state automatically upon expiry of a time alignment timer or upon explicit network signaling while in a different connected state.
