A method for controlling a number of user equipments in a cellular network, the network comprises at least one user equipment (4), a first interface (1) comprising a probability algorithm capable of connecting the user equipment to a second interface (2). The second interface (2) comprises the probability algorithm and is capable of connecting the user equipment (4) to a third interface (3) comprising the probability algorithm. The user equipment (4) sends an attach request to the first interface (1), the first interface (1) sends a create session request to the second interface (2) and the second interface (2) sends an authentication request to the third interface (3). The load on the third interface (3) is indicated by a first flag set in the response from the second interface (2) to the first interface (1). The value of the first flag in the response is calculated by the probability algorithm in the second interface (2). The first flag in the response from the second interface (2) to the first interface (1) is submitted to the first interface (1) and if the first flag indicates that the load on the third interface (3) is too high, one or several actions from the group comprising, the first interface (1) disconnecting the user equipment (4), aborting the procedure, delaying the procedure, and retrying the procedure towards a different secondary interface, are carried out.
