Abstract
A base station transmits to a second base station, a first message comprising a first RAN area identifier of the first base station. The first base station receives from the second base station, a second message comprising a second RAN area identifier of the second base station. The first base station transmits to a wireless device, RRC message(s). The RRC message(s) comprises the first RAN area identifier. The RRC message(s) indicates a state transition of the wireless device to an RRC inactive state. The first base station receives packet(s) for the wireless device. The first base station transmits to the second base station, and in response to receiving the packet(s), a RAN paging message when the first RAN area identifier is identical to the second RAN area identifier. The RAN paging message comprises an identifier of the wireless device and the first RAN area identifier.
