In the present document, the following terms and definitions apply.
Common Part (of a user profile): Contains Initial Filter Criteria instances that should be evaluated both for registered and unregistered Public User Identities, or for unregistered Public Service Identities in the S-CSCF.
Complete user profile: Contains the Initial Filter Criteria instances of all three different user profile parts; registered part, unregistered part and common part.
IP Multimedia session: IP Multimedia session and IP Multimedia call are treated as equivalent in this specification.
Authentication pending flag: A flag that indicates that the authentication of a Public User Identity – Private User Identity pair is pending and waiting for confirmation.
Implicitly registered Public User Identity set: A set of Public User Identities, which are registered and de-registered simultaneously when any of the Public User Identities belonging to that set is registered or de-registered.
Not Registered State: Public Identity is not Registered and has no S-CSCF assigned.
Private Identity: Either a Private User Identity or a Private Service Identity.
Public Identity: Either a Public User Identity or a Public Service Identity.
Registered State: Public User Identity is Registered at the request of the user and has an S-CSCF assigned.
Unregistered State: Public Identity is not Registered but has a serving S-CSCF assigned to execute Unregistered state services as a consequence of a terminating request, or an originating request from an AS on behalf of a user, or there is an S-CSCF keeping the user profile stored.
User information: The user related data that the S-CSCF requests from the HSS or HSS pushes to the S-CSCF, e.g. user profile, charging information, allowed WAF and/or WWSF identities and authentication information.
User profile: Data that is sent in the resource associated to the complete user’s subscription data.
IP Multimedia session: IP Multimedia session and IP Multimedia call are treated as equivalent in this specification.
Transparent data: Data that is understood syntactically but not semantically by the HSS. It is data that an AS may store in the HSS to support its service logic. One example is data that an AS stores in the HSS, using it as a repository.
Non-transparent data: Data that is understood both syntactically and semantically by the HSS.
AS (Application Server): a term used to denote either of a SIP Application Server or an OSA Service Capability Server.
