There is provided a solution as to how the authentication and thus the authorization of the webRTC IMS Client can be achieved in the IMS of the mobile network operator. The WIC (20) is using an ID to register with IMS, which may be an IMPU, an IMPI, gGRUU etc. The WIC (20) may be preconfigured by the WWSF (30) with the eP-CSCF (40) address and authentication information, but if not, then this information should be retrieved via the WWSF (30) or from the IMS directly or via other device management procedures e.g. OMA DM. It is further assumed that the subscriber has already a valid webRTC account/membership and this can be validated, authenticated and authorized by the WWSF (30). |
