9. A method, comprising:
receiving, when a user equipment (UE) is entering an inactive state, an indication of a routing area comprising a plurality of cells, wherein the indication comprises a list of cells in the routing area, wherein the indication is received during radio resource control (RRC) messaging between the UE and a base station;
entering, when the UE is in the inactive state, into the routing area comprising the plurality of cells;
reselecting to a new cell without performing a handover procedure; and
performing a cell update procedure, comprising at least one of:
performing the cell update procedure with a cause value indicating a routing area change if the UE reselects to a cell that is not part of the routing area, and
performing the cell update procedure if the UE has uplink data for transmission.
