An apparatus for controlling a radio bearer reconfiguration in a cellular communication system, such as a UMTS communication system, comprises a reconfiguration instigator ( 301 ) which initiates a radio bearer reconfiguration for a radio bearer supporting a communication between a base station ( 105 ) and a user equipment ( 107 ). Rather than using a static worst case estimate, a reconfiguration switch time processor ( 309 ) determines a reconfiguration switch time in response to a dynamic parameter of the radio bearer reconfiguration process. In particular, the radio parameter may be a size of a radio bearer configuration message transmitted to the user equipment ( 107 ). The reconfiguration switch time is transmitted to the base station by a base station communication processor ( 311 ) and to the user equipment ( 107 ) by a UE communication processor ( 313 ). The base station ( 105 ) and the user equipment ( 107 ) reconfigure their circuitry to apply the reconfigured parameters from the reconfiguration switch time.
