A particular authentication-based service is implemented via a physical authentication device (CRD), e.g. a credit card. A service description (SE) of the particular authentication-based service is read out from the physical authentication device (CRD) via a user terminal (100); and based thereon, a service request (S-REQ) is generated, which also specifies a capability description of the user terminal (100). A communication node (DN) receives the service request (S-REQ) and checks this against a database (DB) containing information about which node in a set of nodes (SP1, SP2,..., SPn) that stores downloadable software for implementing which authentication-based services on which types of user terminals. If a match is found between at least one node (SP1, SP2) in the set of nodes (SP1, SP2,..., SPn) and the particular authentication-based service, a download identification message (ID:SP2) is sent to the user terminal (100). The download identification message (ID:SP2) specifies at least one address string uniquely identifying a respective location for the downloadable software stored in the at least one matching node (SP1, SP2). The downloadable software is configured to implement the particular authentication-based service on the particular mobile communication apparatus (100). |
