The present invention relates to a method for UE context setup in an eNodeB for a UE subscriber in an infrastructure network. The network comprises at least one eNodeB providing radio access for the UE and an MME connected to the eNodeB. The eNodeB/-s comprises an inactivity timer releasing the UE context being setup in the eNodeB after a defined time period. The network for each UE context setup performs the steps of: the UE sending a setup request to the eNodeB, wherein the eNodeB in response to said request sends an initial UE message to the MME to initiate the UE context setup, the UE message identifying the UE sending the setup request; the MME in response to said UE message sending an initial UE context setup request to the eNodeB, wherein the eNodeB responds to the MME with an initial context response complete to finalize the UE context setup; and the MME in the setup request sending timer setup information for said UE, on which basis the eNodeB configures the time period of the inactivity timer for the UE context being setup. The present invention also relates to a MME and an eNodeB adapted for the same purpose.
