3. TISPAN Subscription Management • Objectives: • Allows service providers to provision their TISPAN NGN network entities with the data necessary for delivering services for a specific subscriber. • allows subscribers to configure their services when they have these capabilities. • Consist in the specification of: • An end-to-end information model to cover all the mandatory/optional information related to subscription management that shall be provisioned on the NGN Network. • A subscription management functional architecture which hides the complexity of the different functional entities to be configured including the CPE and the AS.

4. Overview • Allows service providers to leverage their network resources to: • Validate (register, authenticate, and authorize.) a request for service from a user; • Collect, store, update, and distribute the Service Profile information for the user; • Select the trusted network resources to manage access, distribution, and control of the profile data information for the user; and • Direct the network resources to promptly deliver the service requested to the user according to said profile information. • fulfils the following essential TISPAN NGN requirements: • "User equipment Diversity" allows the users to access their TISPAN NGN services by a variety of UEs. • "Service Diversity" allows the users to access TISPAN NGN services provided by service providers or third party application server providers. • "Access Diversity" allows the users to access their TISPAN NGN services over a wide variety of network access such as xDSL, WLAN, GPRS, etc. • "Noamdism": allows the users to access their TISPAN NGN services in multiple nomadism scenarios.

5. Standards in Progress • 3 Work Items • 08015-1: Subscription Management Requirements (TS 188 002-1) • 08015-2: Subscription Management Information Model (TS 188 002-2) • 08015-3: Subscription Management Functional Architecture (TS 188 002-3) • Currently • Requirements: draft v0.0.10 : 12tTD350r1 • Approved standard • Information Model : draft v0.0.5 • Functional Architecture: table of contents.

SuM Requirements • Some Definitions • Offered Services, Subscribed Services, User Assigned Services, User Activated & Customized Services" • Value Chain Model • Definition of a high level use case • Definition of detailed use cases • Help in the design of the information model and the specification of the provisioning interfaces. • It was agreed to describe use cases using 3GPP TR 32.803: Process Guide: Use Cases in Unified Modelling Language (UML). • High Level Requirements • Requirements on Information Model • Re use of 3GPP SUM NRM if possible. • Requirements on Functional Architecture • Re use of 3GPP IRP and 3GPP GUP if necessary • Requirements on NGN entities • Security Requirements • Annex • Example Scenarios of TISPAN SuM

9. SuM Information Model • Current version: draft v0.0.5 • High Level Model • Identification of candidate entity groupings that need to be modelled, possible relations between those groupings and the associated candidate attributes. • Does not specify any information model, but is used as the basis for the design of the SuM Information Model. • The attributes are the one defined within TISPAN & 3GPP (Services, Architecture & protocols) + other attributes if needed • Information Object Classes • Based on 3GPP TS 32.151 Template. • Annex A: SuM Information Reference Table • Information used within this specification, and its corresponding definition and location in 3GPP and TISPAN specifications. • Annex B: Summary of SuM Information • Give the sub clause within this document where SuM Information are used.

TISPAN WG8 / 3GPP SA5 Harmonization • SuM Requirements • Definitions • Define common requirements for Fixed/Mobile Convergence ? • Use Cases ? • SuM Information Model • Needed in order to reuse the 3GPP SUM IRP • Start Harmonization from the High Level Model and not from the object classes. • SuM Functional Architecture • Study the NGN OSS Service Interface reuse of 3GPP IRP ? • At which level SUM IRP can be used according to eTOM ? • The use of 3GPP Generic User Profile ? • Need to take in account the 3GPP/TISPAN collaboration work • General Question : • What is 3GPP SA5 objectives and plan for Subscription Management in Next Releases ?

17. Proposal for 3GPP SuM NRM IS Reuse in TISPAN • In order to reuse the 3GPP SUM within TISPAN, we propose to proceed as follows • Review the 3GPP SUM NRM according to the TISPAN High level model • Introduce the concept of User • Introduce the network access • Some 3GPP SUM NRM IOC can be reused as they are with some modifications • SuMSubscriberProfile • SuMServiceProfile • SuMSubscribedService

18. TISPAN WG8 / 3GPP SA5 Harmonization • SuM Requirements • Definitions • Define common requirements for Fixed/Mobile Convergence ? • Use Cases ? • SuM Information Model • Needed in order to reuse the 3GPP SUM IRP • Start Harmonization from the High Level Model and not from the object classes. • SuM Functional Architecture • Study the NGN OSS Service Interface reuse of 3GPP IRP ? • At which level SUM IRP can be used according to eTOM ? • The use of 3GPP Generic User Profile ?

19. TISPAN SuM Functional Architecture vs 3GPP • Which part of the eTOM business process are realized by 3GPP SUM IRP ? • Service Configuration & Activation ? • Resource Provisioning ? • How 3GPP SUM IRP and 3GPP GUP are related to each other ? • Can we move current 3GPP SUM IRP toward SOA principles? • May be using Web Services ? • Is there any roadmap ?

20. SuMSubscriptionProfile Additional Slide3GPP SuMSubscriptionProfile IOC • This class represents user’s subscription profile of the services contracted by a subscriber. • This class contains Service Profiles for the services contracted by a subscriber and assigned to a user. One User is limited to a single: IMPI, IMPU
