• Deregulation impacts
• More organisations able to offer Telecom Services• Organisations can perform more than one role• Organisation roles no longer static
Drivers: Deregulated Telecom Market
• EURESCOM TMN Model (1994)
– Based upon concept of• Public Network Operator (PNO)
• Regulated Monopolies

OSS Framework Studies
• Goal
– Generic European Processes/components for OSS Interconnect
– Follow NMF Common Interconnection Gateway ‘Use cases’ and Information Model Approach
• Capture Regulatory Requirements
– European
– National
• Adapt integrate other work
– EURESCOM P609 Process Modelling
– TINA -C Reference Framework and Reference Points
– Roles and and relationships

Number Portability (NP) Case Study
TMN WorkshopAntwerp, 27 May 1998
Dave [email protected] +44 1473 64901
European Legislation on NP
• EC directive (for 1/1/2000)
– by 1/1/1998: identification of technical, operational or regulatory barriers
– by 1/6/1999: removal of all national regulatory barriers – From 1/1/2000,
• European customers will be able to demand that NP is immediately established between operators
• Currently NP is established on a bi-lateral agreement based on company readiness.
• Countries with NP deployed
– UK, Netherlands, Denmark, France,….
• Countries with plans to meet 2/1/2000 directive
– Italy,...…

ETSI Number Portability Study
• ETSI Number Portability Task Force
– Provides analysis of network solutions
– Provides a set of network implementation options
– Documented in Task Force Reports• Service Definition
• Network Options
• ETSI Service Provider Portability
– Geographic GNP (UK) and Local Number Portability LNP (USA)
– non-Geographic NGNP also 800 service (USA)
• ETSI Location Portability
– Retain number when moving within a region
TMN WorkshopAntwerp, 27 May 1998

Scope of P811 NP study
• Analysis of Regulatory Requirements
– Phase 1 National and European
• Development of OSS Scenarios and Solutions
– Customer to Service Provider interfaces
– Service Provider to Service Provider interfaces
– Common solutions for Service Provider portability
• Develop Repair and Provisioning processes
• Information models
• Evolution to centralised number administration and porting facility
• European NP Administration Centre (ENPAC) Proposal

• It is essential that order-handling is automated when volume traffic is realised. • The early definition of the order-handling interface is vital.• It must be standardised across all carriers.

P811 Number Portability - initial results
• Business interaction model based on roles
• Cover Geographic and Non Geographic
• Model of Numbers, Number Ranges and Regulators
• Demise of Number ranges
• Model ‘Number’, reservation and administration processes
– Allocation processes
– State model
– Access users, processes and access/security rules
• Model Number Porting Processes
• ENPAC Euro NP Administration Centre – -a physical instantiation of
• Number /plan administration
• Number porting administration / agency
• Number reservation agent role

Charging and Accounting Case Study
TMN WorkshopAntwerp, 27 May 1998
Dave [email protected] +44 1473 64901
P811 Charging and Accounting
• Context
– Deregulation impacts:• transparency, Equal access,• cost representatives.
– Work in progress in ITU, ETSI on signalling protocol to provide Charging Data e.g. DSS1, ISUP, INAP, SCP to SCP.
– Work in progress in other forums like NMF on BAC
– Agreements on SP/NO or NO/NO about circuit or service usage.
TMN WorkshopAntwerp, 27 May 1998
Dave [email protected] +44 1473 64901
P811 Charging and Accounting
• Major topics
– On line charging and call processing are tightly linked, for example, in Call Detail Records generation
– On line Charging for services provided also by Network Operators and Service Providers
– Off line covered Accounting and every aspects using CDRs transferred from network or service provider until billing requirements
TMN WorkshopAntwerp, 27 May 1998
Dave [email protected] +44 1473 64901
P811 Charging and Accounting
• The expected result is:
– To get generic aspects of OSS interconnection on this subject and on both side SP and NO by extending what is still existing
– To cross requirements amongst the two level network and OSS
– To extract what is needed and useful for services in particular NP
– To open up on mobility with service like Virtual Home Environment

Summary
• Driven by deregulation and regulation
• Requirements and analysis focused
• Generic Framework for OSS interconnect– Follows NMF CIGP model
• Development of Numbering and Porting models– Logical roles– Model of ‘Number’– State model for Number – Processes for management of: Numbers & Porting– Covering repair and provisioning processes
• Charging and accounting– OSS and network interconnect– On-line and off-line
