<p>For use in radio resource control (RRC) in a cellular communications network, at a user equipment a first random access channel (RACH) message is generated 300. The user equipment causes transmittal, on a RACH, of the first RACH message 302. The first RACH message comprises an indication that at least a second RACH message, associated with the first RACH message, is to be transmitted subsequently from the user equipment on the RACH. The first RACH message comprises an identifier identifying at least the first RACH message and the second associated RACH message as being a sequence of RACH messages. The identifier may comprise an identifier for the user equipment and identifies how many RACH messages are in the sequence of RACH messages. The first RACH message may comprises an RRC connection request message or a cell update message. Provides connectionless data transmission suitable for Machine Type Communications (MTC) such as used in Smart Meters.</p> |
