Abstract
Disclosed is a method of granting a client communications terminal access to a subscription module of a server communications terminal, the method comprising the steps of establishing a communications link between the client communications terminal and the server communications terminal; communicating data related to the subscription module between the server communications terminal and the client communications terminal via the communications link; authenticating the client communications terminal by the subscription module using a key-based authentication procedure; and initiating the step of communicating data related to the subscription module conditioned on a result of the step of authenticating the client communications device. The present invention further relates to an arrangement for granting access to a subscription module in a communications system. The present invention also relates to a server communications terminal comprising a subscription module, a client communications terminal and a subscription module.
