Method for enhancing the usage of user equipment resources and/or network resources in a mobile communication network by preventing the use of certain radio cells by user equipments in the mobile communication network , wherein the mobile telecommunications network comprises an access network , wherein a user equipment is located in a radio cell of the access network , the radio cell being served by a serving base station entity , wherein the user equipment - besides receiving radio signals from the serving base station entity - at least potentially receives radio signals also from target base station entities , each target base station entity having assigned a scrambling code, respectively, wherein the serving base station entity transmits a blacklist information regarding scrambling codes to the user equipment , the blacklist information referring to at least one blacklisted scrambling code of at least one blacklisted base station entity that shall be prevented to be used by the user equipment , wherein the method comprises the following steps: -- transmitting, in a first step, a measurement configuration information from the mobile communication network to the user equipment , the measurement configuration information comprising an indication, to the user equipment , to perform measurements with regard to the target base station entities , wherein a control channel of the mobile communication network is used for the transmission of the measurement configuration information, wherein the measurement configuration information is split into a part, which contains the blacklist information and which is transmitted via a broadcast control channel, and an additional part, which contains further measurement configuration data describing the intended usage of the at least one blacklisted scrambling code and which is transmitted via a user specific configuration information using a dedicated control channel, -- conducting, by the user equipment and in a second step subsequent to the first step, the requested measurements and thereby obtaining a local network information, -- transmitting, in a third step subsequent to the second step, the local network information from the user equipment to the serving base station entity , wherein the at least one blacklisted base station entity corresponding to the at least one blacklisted scrambling code is either prevented to be measured in the second step or a measurement result corresponding to the at least one blacklisted scrambling code prevented to be transmitted to the base station entity in the third step. -- transmitting, in a first step, a measurement configuration information from the mobile communication network to the user equipment , the measurement configuration information comprising an indication, to the user equipment , to perform measurements with regard to the target base station entities , wherein a control channel of the mobile communication network is used for the transmission of the measurement configuration information, wherein the measurement configuration information is split into a part, which contains the blacklist information and which is transmitted via a broadcast control channel, and an additional part, which contains further measurement configuration data describing the intended usage of the at least one blacklisted scrambling code and which is transmitted via a user specific configuration information using a dedicated control channel, -- conducting, by the user equipment and in a second step subsequent to the first step, the requested measurements and thereby obtaining a local network information, -- transmitting, in a third step subsequent to the second step, the local network information from the user equipment to the serving base station entity , <EOS>
