World Class Standards 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.

World Class Standards 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.

World Class Standards 5 Standards in Progress  3 Work Items  : Subscription Management Requirements (TS )  : Subscription Management Information Model (TS )  : Subscription Management Functional Architecture (TS )  Currently  Requirements: draft v : 12tTD350r1 Approved standard  Information Model : draft v0.0.5  Functional Architecture: table of contents.

World Class Standards 8 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 : 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

World Class Standards 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 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.

World Class Standards 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

World Class Standards 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 ?

World Class Standards 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 ?
