1. A method comprising:
receiving, by a first base station from a second base station, information including a cell identifier (ID) of the second base station;
identifying, by the first base station, a packet for a wireless device in a radio resource control (RRC) inactive state; and
in response to the identified packet, transmitting, by the first base station to the second base station, a radio access network (RAN) paging message based on RAN paging area information related to paging in the RRC inactive state,
wherein the RAN paging message comprises an identifier of the wireless device, paging discontinuous reception (DRX) information, and the RAN paging area information related to paging, and
wherein the RAN paging area information related to paging comprises at least one of RAN area identifiers and at least one of cell identifiers.
