US Patent 10368334 Radio access network paging area configuration

A base station receives from a second base station, first packet(s) associated with a wireless device. The base station receives from a core network entity, second packet(s) for the wireless device when in an RRC inactive state. The base station transmits a first RAN paging message to a third base station of a RAN area associated with the wireless device in response to a time duration being larger than a time value. The time duration is the time between the receiving of the first packet(s) and the receiving of the second packet(s). The base station transmits a second RAN paging message to the second base station regardless of the time duration being smaller or larger than the time value. The base station transmits second packet(s) to the second or third base base station based on a response received for the first or second RAN paging message.
