One method includes determining that an update of a radio access capability for a first radio access technology is required based at least in part on whether to use a second radio access technology. The method includes switching to an idle state based on determining that the update of the radio access capability for the first radio access technology is required and transmitting a request message indicating that the update of the radio access capability for the first radio access technology is required in response to switching to the idle state, the request message further indicating to delete a stored radio access capability associated with the UE and obtain a new radio access capability associated with the UE.

The invention relates to an improved semi-persistent resource allocation for a mobile terminal (MT) for transmitting periodic data. The MT transmits information on the periodic data to the radio base station (BS), such that the BS determines the different possible transmission periodicities and/or the different possible message sizes of the data components of the periodic data. The MT receives from the BS plural semi-persistent resource (SPS) configurations, each being usable to transmit at least one of the supported data components. The MT indicates to the BS the data components that are to be transmitted by the MT. The MT receives from the BS an activation command to activate one or more of the SPS configurations to periodically allocate radio resources for the MT to transmit each of the indicated data components. The MT then transmits the one or more data components based on the radio resources and the transmission periodicity as configured by the activated one or more SPS configurations.
