Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet
converged Services and Protocols for Advanced Networking (TISPAN).
The present document describes the Service and Capabilities Requirements of TISPAN NGN Release 1.
Introduction
The present document specifies the requirements that need to be fulfilled by NGN technical specifications to provide
services in an NGN.
The present document considers two service sets: IP Multimedia Services and PSTN/ISDN Emulation services. Each of
these service sets has its own clause, which is further divided into clauses providing clear and precise requirements for
each of these two service sets. Further clauses provide generic network requirements to support service deployment and
interoperability.
The present document provides generic requirements on networks from a services point of view. Specific details of
individual services and capabilities are provided in other documents.

1 Scope
The present document specifies network requirements in terms of service-related capabilities for TISPAN NGN. The
present document places requirements for all TISPAN NGN Release 1 subsystems.
The present document provides generic requirements for services and interoperability in TISPAN NGN in terms of the
capabilities for a network or networks.
Requirements on service-related subsystems provide sufficient detail for architecture, networking requirements and
protocols to be specified. Requirements on service independent subsystems are contained within the service-related
subsystem requirements.
Specific service requirements may be contained in other documents, as identified in the present document, and by other
documents referencing the present document.
The present document does not define services, only capabilities and requirements. The present document does not
place requirements on terminals or other customer-owned equipment. The present document specifies the
service-related requirements that are used to determine the network architecture, requirements and control protocols
for a network interface to a customer environment.
NOTE: The present document uses the term "NGN" only in the context of TISPAN.

Any access to the NGN core shall provide IP connectivity, i.e. allow transport of IP packets between end user
equipment and the NGN core.
Solutions for access to the NGN core shall support the assignment of IP addresses to the end user equipment by the
access network. These addresses may not be routable in the public Internet.
Solutions for access to the NGN core shall not require changes to existing access technology infrastructure. All
solutions for access to the NGN core shall support the presence of NAT and firewalls in the access network
environment. Impacts on access networks shall be minimized.

from the end user equipment.
Solutions for access from a customer network to the NGN shall be able to cope with the assignment of IP addresses to
the end user equipment by the customer network. These addresses may not be routable in the public Internet.
Solutions for access from a customer network to the NGN shall not require technological changes to existing customer
network technologies.
Solutions for access from a customer network to the NGN shall have minimal impact on existing customer network
deployments.

10 ETSI TS 181 005 V1.2.1 (2009-12)
4.8.2 Home and Small Office Networks
Solutions for access from a Home and Small Office network to the NGN shall be able to cope with NAT and firewalls
in the home/small office environment.
Solutions for access from a Home and Small Office network to the NGN shall support the following configurations:
• Direct connectivity and interaction between the individual terminals and the NGN.
• Indirect connectivity and interaction between the individual terminals and the NGN (e.g. via IP PBXs).
4.8.3 Corporate Networks
Solutions for access from a corporate network to the NGN shall be able to cope with NAT and firewalls in the corporate
environment.
Solutions for access from a Corporate network to the NGN shall support the following configurations:
• Direct connectivity and interaction between the individual terminals and the NGN (e.g. to support Ipcentrex
configurations).
• Indirect connectivity and interaction between the individual terminals and the NGN (e.g. via IP PBXs).
4.9 Interworking
As specified in TS 122 495 [6].
4.10 Quality of Service (QoS)
The NGN shall support the following:
• A wide range of QoS-enabled services.
• Dynamic negotiation of QoS parameters between service and access providers based on an SLA.
• Terminals that are not capable to indicate QoS requirements as part of the service request. Terminals that are
capable shall also be supported.
• QoS provisioning within the access segment. QoS in the core transport network is considered to be achieved
by other means that are out of the scope of NGN Release 1 (e.g. Overprovision).
• The provisioning of QoS for application traffic where upstream and downstream flows have specific QoS
requirements.
• An architecture that supports bandwidth reservation.
• QoS mechanisms to allow efficient use of access resource.
4.11 Security Requirements
As specified in TS 122 495 [6].
4.11.1 General
As specified in TS 122 495 [6] except the following requirements:

Network.
ETSI

---------------------- Page: 10 ----------------------
11 ETSI TS 181 005 V1.2.1 (2009-12)
• The NGN shall support independent verification by IMS and Access Network of the previous two
requirements.
4.12 Charging and Accounting
As specified in TS 122 495 [6].
5 PSTN/ISDN Emulation Service
5.1 Business Models
The business model envisaged for PSTN/ISDN Emulation Service is the replacement (in whole or part) of an existing
PSTN/ISDN network based on TDM with an Emulation based on IP technology. An alternative business model is the
provision of PSTN/ISDN service over connections derived from broadband service, which compete with the existing or
Emulated PSTN. Both business models may co-exist in the same market place.
A NGN service provider shall be capable of connecting to other service provider via:
• an interconnect model where bi-lateral Service Level Agreements are established between two service
providers;
• an interconnect model where intermediate network(s) can provide interconnect on behalf of multiple service
providers (and may be based on a single Service Level Agreement between the SP and their intermediate
service provider).
A single NGN service provider shall be able to choose to support either of the interconnect models, or both of the
interconnect models simultaneously.
5.2 Service Requirements
The NGN shall support PSTN /ISDN emulation that provides the user with an identical experience to that of the
existing PSTN/ISDN.
The NGN shall support the ability for a service operator to emulate one or more of their PSTN/ISDN services.
The NGN shall support service capability definitions inherited from existing PSTN/ISDN specification. The service
descriptions of the existing services for any particular network are outside the scope of the present document.
It is an objective that the user shall be unaware of a change from legacy PSTN/ISDN to PSTN/ISDN emulation for
those services that are emulated. For each emulated service, the service capability definitions are inherited from existing
PSTN/ISDN specifications. Specific service requirements related to PSTN/ISDN Emulation are described in the
following clauses.
5.3 Mobility
There is no requirement to support mobility or a nomadic capability for PSTN/ISDN Emulation. There are no additional
mobility
