Abstract: Technology for switching a user equipment (UE) from a lightweight radio resource control (RRC) connection to a legacy RRC connection is disclosed. A radio base station can determine that the UE is to switch from the lightweight RRC connection with the radio base station to the legacy RRC connection with the radio base station, wherein the UE is configured to perform small data transmissions when the lightweight RRC connection is established for the UE. The radio base station can instruct the UE to perform a service request procedure in order for the UE to transition from the lightweight RRC connection to the legacy RRC connection. The radio base station can receive a service request message from the UE when the service request procedure is initiated at the UE, wherein the radio base station is configured to facilitate switching the UE from the lightweight RRC connection to the legacy RRC connection.
