Abstract: A method of operating an access node of a radio access network of a cellular network includes participating in an early-data-transmission of a random access procedure of a UE. The method further includes, in response to said participating in the early-data-transmission: determining whether or not the UE requires an update information element of a notification area of the radio access network. The method further includes selectively transmitting the update information element if the UE requires the update information element.
