Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet
converged Services and Protocols for Advanced Networking (TISPAN).
Introduction
The focus of the present document is on Subscription Management (SuM) which is necessary to allow Service
Providers and Operators to offer and deliver NGN services to their subscribers.
SuM is a key feature that allows service providers and operators to provision their TISPAN NGN network entities with
the data necessary for delivering services for a specific subscriber. Moreover, it also allows subscribers to configure
their services when they have these capabilities.
For the services, business aspects such as duration of a subscription, number of times accessing the service, or
pricing/payment are not of concern for SuM as specified in the present document, and SuM covers management of
services irrespectively of such aspects.
SuM aligns with a subset of the eTOM fulfilment process. SuM is concerned with the definition of all the mechanisms
and information needed to efficiently and flexibly configure the TISPAN NGN network with the appropriate data
needed for a specific subscriber.
SuM is a telecommunications management framework that allows the 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.
• Direct the network resources to promptly deliver the service requested to the user according to said profile
information.
Subscription Management (SuM) fulfils the following essential TISPAN NGN requirements:
• The "User equipment Diversity" allows the users to access their TISPAN NGN services by a variety of UEs.
• The "Service Diversity" allows the users to access TISPAN NGN services provided by service providers or
third party application server providers.
• The "Access Diversity" allows the users to access their TISPAN NGN services over a wide variety of network
access such as xDSL, WLAN, GPRS, etc.
• Nomadism: allows the users to access their TISPAN NGN services in multiple nomadism scenarios.

4 Subscription Management (SuM) description
4.1 SuM overview
Allowing service providers to deliver, control, monitor and bill services to their subscribers in a timely and correct
manner, require the translation of each specific subscription into necessary/optional network data and their provisioning
on the appropriate network functionalities such as UPSF, AS, CPE, etc. Subscription Management (SuM) is the feature
that realizes the above translation and provisioning artefacts. Moreover, Subscription Management (SuM) must provide
means that allow subscribers to configure their services when they have configuration access rights.
Subscription Management (SuM) can be summarized as the framework that offer service providers means for efficient
management of all the data related to a specific subscription. This framework is part of the service delivery "processes"
used by the service provider to deliver services for subscribers.
The SuM framework is responsible of handling only the data related to the service delivery of a specific subscription.
Moreover, as depicted in figure 1, data provisioned thanks to the Subscription Management (SuM) framework can also
be used in other processes such as monitoring, billing, etc.
Subscription Management (SuM) framework, as shown in figure 1, involves the following entities:
• Service provider: offers a set of services.
ETSI

---------------------- Page: 7 ----------------------

• Subscriber: may subscribe to one ore more services. The service provide will have then to manage the
corresponding subscription by provisioning the necessary data and giving the following rights to the
subscriber:
- To become a user by using the services.
- Give rights to its users, who will be then linked (or associated) to this subscription.
• User: use the authorized services.

Figure 1: Subscription Management Overview
Subscription Management (SuM) aligns with subset of the eTOM fulfilment process, in particular the customer
relationship management process, the service management and operations process and the resource management and
operation process.
4.2 SuM and eTOM fulfilment process
Subscription Management (SuM) can be viewed as part of the eTOM fulfilment process described in TMF GB921 [i.1].
The eTOM fulfilment process is defined as a vertical end-end process grouping responsible for providing customers
with their requested products in a timely and correct manner. It translates the customer's business or personal need into
a solution, which can be delivered using the specific products in the enterprise's portfolio. This process informs the
customers of the status of their purchase order, ensures completion on time, as well as ensuring a delighted customer.
As shown in figure 2, eTOM fulfilment process is composed of the following process:
• Selling, marketing fulfilment response and order handling: these processes are located within the customer
relationship management process grouping which is responsible of functionalities necessary for the
acquisition, enhancement and retention of a relationship with a customer. The order handling process is
responsible for accepting and issuing orders.
• Service configuration and activation: this process is part of the service management and operations
processes grouping which provide all the functionalities necessary for the management and operations of
communications and information services required by or proposed to customer. The focus of the service
management and operations is on service delivery and management as opposed to the management of the
underlying network information technology. The service configuration and activation process encompasses the
installation and configuration of the service for customers, and support the reconfiguration of the service
(either due to customer demand or problem resolution).
ETSI

---------------------- Page: 8 ----------------------
9 ETSI TS 188 002-1 V3.1.1 (2009-07)
• Resource Provisioning: this process is part of the resource management and operations process grouping
which is responsible of managing all the resources (networks, IT systems, servers, routers, etc.) and delivering
services required by or proposed to customers. The focus of the resource management and operations is to
ensure that the network and information technologies infrastructure supports the end to end delivery of the
required services. The Resource Provisioning process encompasses allocation and configuration of resources
to individual customer service instances in order to meet the service requirements.
• S/P requisition management: this process is part of the Supplier/Partner (S/P) relationship management
process grouping which enable the direct interface with the appropriate lifecycle, end-to-end customer
operations or functional processes with supplier and/or partners. The S/P requisition management process
manage requisitions with partners/suppliers to ensure on-time and correct delivery of the S/P product or
service requested by the enterprise.

SuM feature is the part of the fulfilment process which is responsible of handling and installing the data related to
specific subscription.
Within the eTOM fulfilment process, SuM addresses the following eTOM processes:
• Service configuration and activation.
• Resource provisioning.
The service configuration and activation part of SuM ensures the translation of the subscription into network
information that are independent from the underlying network technology.
The Resource Provisioning part of SuM ensures the configuration of the network information received from the service
configuration and activation. This configuration is done by mapping the network information into the appropriate
network data according to the deployed network technology.
The following table shows the relationship between eTOM fulfilment process and Subscription Management (SuM), in
particular the eTOM level 3 processes applicable to this SuM release.

Figure 4: High level use case diagram
The high level use case diagram comprises the following use cases:
• Manage subscription: this use case is related to the management of a subscription of a specific subscriber.
This use case includes the management of the "offered services" and of the "subscribed services" use cases.
This two uses cases can be defined as follows:
- Manage offered services: refers to the management of the services offered by the service provider to the
market and is part of the manage subscription use case. The management of the offered services by the
service provider is out of the scope of the current release of Subscription Management (SuM).
- Manage subscribed services: refers to the management of the services subscribed by a subscriber
within a subscription and is part of the manage subscription use case.
• Manage user: concerns the management of the users associated to a subscriber. This use case includes the
use cases related to the management of the services assigned by the subscriber to its users.
- Manage user assigned services: refers to the management of the services that are assigned by a
subscriber to a given user and is part of the manage users use case. This consists in the assignment and
the association of specific rights (e.g. activation/deactivation, customization, etc.) of some or all of the
subscribed services to the user.
• Manage user customized and activated services: referes to the management of the services that are assigned
to the user by activating them or not and customizing them or not according to the rights given by the
subscriber. This use case is part of the "manage its assigned services" use case.
• Manage NGN SuM data: this use case refers to the management of the subscribers and their users' data
within the NGN functional entities.
Within the high level use case diagram, four kinds of services are highlighted. The transition from one service to
another is depicted in figure 5.
