主权项

1. Communication apparatus for a cellular communication system, the communication apparatus comprising:
means for operating a first cell using a first component carrier and at least one further cell using a further component carrier; means for communicating with a mobile communication device operating in said first cell; means for determining that an attempt should be made to configure said mobile communication device to communicate using the at least one further cell; and means for transmitting a message to a communication entity of said communication system to initiate a procedure for checking whether configuration of said mobile communication device to communicate using the at least one further cell should be allowed; means for receiving, from the communication entity, a message indicating, for each further cell, whether configuration of said mobile communication device to communicate using that further cell should be allowed; and means for communicating with said mobile communication device to configure said mobile communication device to communicate using each further cell for which a respective indication that such configuration should be allowed has been received such that said mobile communication device is configured to communicate using each further cell for which a respective indication that such configuration should be allowed has been received, and said mobile communication device is not configured to communicate using each further cell for which a respective indication that such configuration should be allowed has not been received.
