Method and arrangement for handling profiles in a multimedia service network

摘要

A method and apparatus for sharing an application profile for plural public IMS identities across different IMS subscriptions. A home application profile for a first public IMS identity (IMPUx) of a first IMS subscription, is stored in its entirety at a first HSS storage. A profile reference is stored as an abbreviated foreign application profile for a second public IMS identity (IMPUy) of a second IMS subscription at a second HSS storage. The profile reference points to the home application profile in the first HSS storage. An authorizing identifier for the second public IMS identity that authorizes access to the home application profile, is also stored at the first HSS storage.
