An apparatus, comprising:

• first determining means for determining, in response to a received cell update message comprising information indicative of a case of an uplink data transmission that is a cause of a cell update, that a first procedure for data transmission is to be used when said cell update message comprises information indicating that the case of the uplink data transmission that is the cause of the cell update comprises a user data transmission;
• and
• second determining means for determining that a second, different procedure is to be used for the data transmission when said cell update message comprises information indicating that the case of the uplink data transmission that is the cause of the cell update comprises a control data transmission, wherein the cell update message comprises a radio resource control message comprising information for use at a network node in carrying out radio resource control.
