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 StandardsOverview
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.

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

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.

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

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 ?
