Why are EURESCOM Partners Why are EURESCOM Partners Collaborating in this Work?Collaborating in this Work?

• Opening of world markets will not see the total decline of correspondent working in the short term

• The granting of more international licenses will require inter-working between many more partners (capacity providers)

• Consistency and automation of process is essential for operational efficiency

• A common understanding and resolution of issues for systems implementation is essential for success

• Results are applicable to all inter-operator connect activities, not just international ‘cross-border’

Operational Process Validation Methods• Investigate methods for validating individual processes against requirements and for validating process interactions

• Methods for performing consistency check of processes

• Recommendations for process checking

System Performance Assessment• Generate test methods for assessment of overall system performance

• Specify testing configurations

• Identify most critical system elements that affect overall performance




Database (MIB) Solutions• Definition of database schema

• Recommendations for database partitioning

• Recommendations for database implementation

• Investigate MIB synchronisation issues and methods

Management Communications• Recommend preferred options for DCN implementation

• Recommend preferred options for protocol choice

• Recommend preferred DCN topology & architecture for management communications resilience

• Identify evolution limitations for DCN

• Identify options for disseminating non-real time information




Evolution Planning

• Identify key factors to be resolved during evolution planning

• Generate check lists for evolution planners

• Recommendations for setting evolution stage targets

• Recommendations for setting and administering version & build control

• Identify issues for working in an environment requiring support to multiple system versions




Application Suitability Methods(for administering the management system)

• Identify & recommend efficient & cost effective test methods

• Generate guidelines for specifying test criteria

• Generate guidelines for pass / fail evaluation

• Recommend ‘problem’ location and resolution methods

• Provide guidelines for the generation of test specifications

• P707 is actively downstreaming results into Standards (ETSI TC/TMN)

• Utilising a realistic case study has greatly enhanced project ability to focus upon genuine implementation problems

• Investigation of real implementation problems is expected to prove useful for other technologies Thank you for your attentionThank you for your attention
