Telecommunication systems comprising base stations ( 1 ) and mobile terminals ( 11 ) generate channelization codes like Orthogonal Variable Spreading Factor codes or OVSF codes defining channels used for communication between base stations ( 1 ) and mobile terminals ( 11 ) and calculate cost functions for these channelization codes. The base stations ( 1 ) are provided with transferors ( 7 ) for transferring ongoing calls from first channels defined by first channelization codes to second channels defined by second channelization codes in dependence of calculated cost functions, to be able to treat ongoing calls dynamically, by allocating channels dynamically to ongoing calls. Said transferring is realized via transferring messages. Preferably a low complex cost function is a function of a sum of products of an occupation parameter and a data rate for at least a specific level and divided by a data rate for a neighboring level, to reduce the processing capacity.
