Method for controlling the access of a user equipment to a mobile communication network, the mobile communication network comprising a plurality of radio cells (11, 12) as part of an access network of the mobile communication network, and the mobile communication network having a network slice and at least one further network slice, wherein the user equipment - being located, among other user equipments, in a specific radio cell of the plurality of radio cells (11, 12) - is attempting to gain access to the mobile communication network using the network slice of the mobile communication network usable within the specific radio cell, -- wherein an access barring of user equipment attempts within the specific radio cell is applied based on access categories assigned to such user equipment attempts such that a predetermined barring probability is applied to such user equipment attempts - the access probability for the user equipment of gaining access to the mobile communication network using the network slice is adapted compared to using a unified access control-mechanism, or -- wherein the access probability for the user equipment of gaining access to the mobile communication network using the network slice is adapted in a network slice-specific manner, wherein the method comprises the following steps: -- in a first step, a network slice priority information is stored in or transmitted to the user equipment or a secure element of the user equipment, wherein the network slice priority information indicates an adaption of an access priority, regarding the user equipment attempting to gain access to the mobile communication network using the network slice, -- in a second step, subsequent to the first step, the user equipment, using the network slice, is provided access to the mobile communication network taking into account the adaption of the access priority, wherein the adaption of the access priority - regarding the network slice by means of using the network slice priority information - corresponds to maximally increasing the access probability such that an access barring based on a unified access control-mechanism is avoided or switched off; or corresponds to increasing or reducing the access probability compared to the probability applying an access barring based on a unified access control-mechanism. -- wherein an access barring of user equipment attempts within the specific radio cell is applied based on access categories assigned to such user equipment attempts such that a predetermined barring probability is applied to such user equipment attempts - the access probability for the user equipment of gaining access to the mobile communication network using the network slice is adapted compared to using a unified access control-mechanism, or -- wherein the access probability for the user equipment of gaining access to the mobile communication network using the network slice is adapted in a network slice-specific manner, -- in a first step, a network slice priority information is stored in or transmitted to the user equipment or a secure element of the user equipment, wherein the network slice priority information indicates an adaption of an access priority, regarding the user equipment attempting to gain access to the mobile communication network using the network slice, -- in a second step, subsequent to the first step, the user equipment, using the network slice, is provided access to the mobile communication network taking into account the adaption of the access priority,
