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 (310, 320), each target base station entity (310, 320) 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 (310, 320), 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 (310, 320), 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,
