3 OSS Integration! Building and Integrated architecture that allows Processes and Data to Flow seamlessly is a big challenge in OSS! An ideal architecture should allow for systems to be altered, added and removed without requiring massive rewrites and conversions! Technology can be an enabler but integration requires significant analysis and testing as well as development efforts. TÓPICOS AVANÇADOS EM REDES ADVANCED TOPICS IN NETWORKS 3

4 OSS Integration Objectives! Order Flow-Through! Service Assurance Flow-Through! Integrated Customer View! Data Synchronization TÓPICOS AVANÇADOS EM REDES ADVANCED TOPICS IN NETWORKS 4

5 OSS Integration Objectives! Order Flow-Through: To manage interactions among applications for order-processing workflow! Requiring: Sequencial and parallel activities coordinated across multiple systems! Involves: Sales Force Automation, Order Entry, Order Management, Provisioning, Activation, Interconnect GW, Billing... TÓPICOS AVANÇADOS EM REDES ADVANCED TOPICS IN NETWORKS 5

6 OSS Integration Objectives! Service Assurance Flow-Through: To detect faults and correlate to affected customer! Requiring: Automatic Trouble Ticket generation! Involves: Network Management, Trouble Ticket system, Service Level Management (SLA credits calculation), Billing Customer originated Trouble Tickets (via Web Portal or Contact Center)! Requiring: Ticket to be flowed to appropriate application for resolution! Involves: Web Portal, CRM, Trouble Ticket system, Service Level Management (SLA credits calculation), Billing..

7 OSS Integration Objectives! Integrated Customer View: Requires Real-Time flow with immediate access to customer data! Data is requested and synthesized from multiple systems! Involves: Web Portal, Network Management, Trouble Ticket system (outstanding Tickets), Order Management (Order Status), Billing (recent billing activity and status),...

8 OSS Integration Objectives! Data Synchronization:! In an ideal OSS, applications would share a common database obviating redundant data! In reality each OSS application has its own proprietary data model and data store! In order to build an Integrated OSS it is necessary to establish for each data subject area a master system of record for data entities (without a master it is impossible to determine the event and transaction flows to achieve integration.

9 Transactions and Flows! Sales Force Automation transactions:! Service Availability! Scheduling! Order Capture! Web-Based Care Transactions:! Order Entry! Order Status! Billing Presentment! Policy Management TÓPICOS AVANÇADOS EM REDES ADVANCED TOPICS IN NETWORKS 9

10 Transactions and Flows! Order Management and Provisioning transactions:! Supplier Gateway! Work Force Management! Network Activation! Service Testing! Billing Transactions:! Customer Profile maintenance! Order Completion! Financial (General Ledger) feed TÓPICOS AVANÇADOS EM REDES ADVANCED TOPICS IN NETWORKS 10

11 Transactions and Flows! Network Monitoring transactions:! Fault Detection and Correlation! Trouble Ticket Generation! Dispatching! Service Testing! Web-Based Care Transactions:! Trouble Entry / Trouble Status! SLA Credits TÓPICOS AVANÇADOS EM REDES ADVANCED TOPICS IN NETWORKS 11

12 Common Integration technologies! Point-to-Point Integration! Integration of applications in a pair-wise fashion! Enterprise Application Integration (EAI)! Common technical approach around a middleware infrastructure! Middleware provides a bus or backplane among applications! Applications are connected to the bus via adapters or connectors TÓPICOS AVANÇADOS EM REDES ADVANCED TOPICS IN NETWORKS 12
