A User Equipment (UE), a Home Subscriber Server (HSS), and methods are provided for facilitating access to a second service (e.g. IPTV, IP Television) when the user registers with a network for a first service (e.g. IMS, IP Multimedia Subsystem service, or 2G mobile service). For example, the user employs his mobile terminal to register for IMS service, then requests a security token for the provision of the second service. The network validates the user subscription and provides the security token associated with the 2nd service, e.g. with IPTV. The user can input the security token for obtaining access to the 2nd service, e.g. from another terminal. For example, the user can input the token, e.g. in the form of a PIN code, on an ITF (IP Television Terminal Function) to be provided personalised IPTV service, or for performing IPTV parental control on his IPTV subscription involving multiple users. |
