Interaction Model :managing role( information user)/ managed role( information resource) ex. manager/agent, client/server, invoker/responder, peer-to-peer, publisher/subscriber, consumer/producer Information Model is composed of Information Elements( = objects) Information Architecture is unified at Reference point into TMN functional architecture and LLA.

TOM : Telecom Operations Map A Service Management Business Process Model (TMF : TeleManagement Forum 1995) http://www.tmforum.org Customer Customer Interface Management Process Information Systems Management Processes Customer Care Process Sales Order Handling Problem Handling Customer QoS Management Invoicing/ Collections Service Management Service Development and Operations Processes Service Planning/ Development Service Configuration Service Problem Resolution Service Quality Management Rating and Discounting This shows the overall Telecom Operations Map that is the framework for understanding the relationships among individual process flows. The Telecom Operations Map uses the layers of the TMN model as core business processes, but divides the service management layer into 2 parts: Customer Care and Service Development and Operations. In the simplest sense the division reflects differences between processes triggered by individual customer needs from those applied to a group of customers subscribed to a single service or service family. It also reflects the accountability for direct customer contact handling in Customer Care processes. Depending on the provider, Customer Interface Management may be managed within the individual Customer Care sub-process or, in combination across one or more of the Customer Care sub-processes. For this reason, Customer Interface Management is separately delineated.

Scenarios for Mediation/Migration Case 2 Plug & Play Mediation Case 4 Add Mediation NMS (Integrator) = Mediation Function Ex. CORBA IDL SNMP CMIP Etc.. XXXX ZZZZ Case 1 Mediation Box (Adaptor) Case 3 Add Mediation Library Here we will discuss NMS as an integrator of EMSs and the location of Mediation function to hide the differences of interfaces of EMSs. 1, When a new integrator is developed to integrate current and future EMSs, it should be a design goal to be able to meet all interface requirements by the use of Plug and Play concepts. Standard interfaces, SNMP, CMIP, TL1, etc.. should be supported in this way, also the software architecture should support the addition of new components as new standards emerge. Within this framework specific proprietary interfaces can be met by the application of case 1. 2, However most existing NMSs have not been developed in this manner, They were designed and developed with specific interfaces in mind. When interfaces have to be accommodated that weren’t originally planned for, then either Case 1 or Case 3 will normally be applied to migrate EMS into an integrated structure. meaning that case 1 or 3 would need to be utilised, we recommend the replacement of these systems by those that deploy a Plug and Play framework as in the long term, this will provide the most cost-effective solution.

Communications Technology Services NGOSS Framework TM NGOSS Registry TM NGOSS Shared Data Model TM Process Definition Tool BAC BAC BAC BAC Communications Technology Services WFE concept will become more powerful if software(process) component concepts are deployed. TMF is the current focus for Business Process Standardisation and is also now considering Process Component Standardisation under its NGOSS initiative. The TMF NGOSS Technology Neutral Architecture as shown identifies a set of process components. By separating the work flow scenario(as this is subject to frequent change, both on a time and a Service Provider basis) from the application components tremendous flexibility/reusability can be obtained in the area of process integration. The components identified by NGOSS as common software services and common date groups have been decomposed as far as possible to realise highest software reusability. However, we believe that in practice when undertaking OSS development, making a number of clusters ( packages) combining a number of closely related components will be better for high performance and easy handling.
