Scope of the WI
Produce an ETSI Technical
Report Create a common understanding on
IMS Testing Infrastructure.
Define IMS Testing Methodology
Define IMS Network Configurations
df
The IMS CN should enable the convergence of, and access to, voice, messaging, data and web-based technologies for the wirless user. For the definition of a complete IMS Network Integration Testing Infrastructure will be necessary to define Network Configurations where the nodes involved interwork through the various interfaces (IuPS, Gn, Mw, Gm, Go, Mi, Mj, Mk, Mg, Mn/Mc, Cx and Rf. ). PCO and PO will be defined for configurations dealing with:Single Operator’s Network ArchitectureMultiple Operators’ Network ArchitectureRoaming Configurations

Outline
• Global Network Architecture• IMS Architecture• Testing Tipologies• Scope of Testing• Proposed Configurations• Conclusion
Testing Typologies
4. Live Testingcheck the correct handling of the system’s functionalities in a real context
2. Conformance Testcheck the functional blocks compatibility
3. Load & Capacity testing• check the performances declared by supplier• check the correct working in limit load conditions
1. Functional Testing• check the correct handling of the system end-to-end functionalities verifing protocols and procedures• tipically carry out in test plant
Scope of Testing
Verify the IMS core-network through the usage of a set of reference end-to-end scenarios (including roaming users) and the analysis of signalling on the network interfaces that are involved: Gm, Cx, Mw, Mi, Mj, Mk, Mg, Mn, Rf, Go.
• Verify the procedures conformity to the standard• Reduce the time to market of new network solutions

Session Control & Enhanced Multimedia services
IMS configuration requiring two user located in the same home network for testing:
- Session setup and Session control procedures (Session initiation, Session Release, Network initiated release procedures, Unsuccessful session handling like user busy, rejected session, user not registered or unreachable)
- Enhanced Multimedia services (Session hold and resume, handling of privacy, codec and media flow negotiation, session redirection and session transfer in case of three user)
