• receiving from a core network a first control message containing a first information element relating to a radio terminal, wherein
• the first information element indicates at least one of:
• an amount of data available to the radio terminal;
• or
• whether or not one or both of carrier aggregation and dual connectivity are required or allowed with respect to the radio terminal.

A core network node comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and configured to send to a radio access network node a first control message containing a first information element relating to a radio terminal, wherein
