The present invention is related to a method for radio resource handling in a wireless communication network comprising the steps:—receiving via a transport network interface a request for assignment of one or more radio resources over an air interface of the wireless communication network;—transmitting via the air interface a radio resource assignment message for one or more one radio resources in the wireless communication network;—receiving a radio resource assignment confirmation message over the air interface;—transmitting a radio resource assignment confirmation message over the transport network interface, wherein the radio resource assignment message transmitted via the air interface comprises a single radio resource assignment message configured to simultaneously perform establishment, release and modification of one or more radio resources provided by over the air interface. This method may be implemented by a computer program comprising instruction sets for each method step. Also, the present invention comprises a radio base station and a mobile terminal where the method according to the present invention may be executed.
