ITU Regional Consultation on
Conformance/Interoperability
Nairobi, Kenya
What is the MSF?
• The MultiService Forum (MSF) is a global association of
service providers and system suppliers committed to
developing and promoting open-architecture, multiservice
switching systems.
• Founded in 1998, the MSF is an open-membership
organization.
• The MSF’s activities include developing implementation
agreements, promoting worldwide compatibility and
interoperability, and encouraging input to appropriate
national and international standards bodies.
• For more information about the MSF and its members, visit
the MSF web site at www.msforum.org.

Where the MSF Fits
• MSF is not a Standards Development Organization
(SDO)
• Focus on developing meaningful physical
implementations of standards
• Use of large-scale interoperability events to test and
validate standards implementations of interest to major
carriers
• Provides significant resource for members to leverage
for achieving multi-vendor solutions
• Provides key implementation feedback to vendors,
carriers and SDO’s

Framework
Physical Scenarios
Interop testing is only meaningful in the
context of a specific network configuration
Options must be specified, and ambiguities
clarified
Protocol Selection
MSF IA’s
Test Plans
Testing & Interoperability
Programmes
Validated, commercially viable
Implementation Agreements (IAs)
Detailed test plans required to ensure
complete coverage and consistency
Interop program requires start-to-finish
program management and coordination
Interop programs are best at validating the
standards (not products)

MSF Delivery Process
•
Focus on accelerating the deployment of new technologies
emerging from standards by supporting interoperability and
test events as required by MSF members
•
Rapid development model
– Mapping of SDO architectures to real world implementations
– Develop physical scenarios
– Develop detailed test cases
– Profile protocols where necessary to facilitate the testing
•
Provide key implementation feedback to vendors, carriers and
standards organisations

EPC / LTE Interop Event
• MSF EPC/LTE Interoperability Event was hosted
March 15 – 20, 2010 by the Vodafone Test and
Innovation Centre, Dusseldorf, Germany and China
Mobile facilities in Beijing
• Designed to test standards compliance of vendors
implementation of Evolved Packet Core (EPC) network
scenarios to 3GPP Release 8 standards
• Gauge vendor support for this technology
• Mix and match of different vendor EPC network
elements to test interoperability
• Performed inter-site and intra-site testing
• 8 Vendors participated in the event

Project Plan
Hire full-time Event Coordinator
Determine host sites i.e., carrier labs
Project Requirements Document (PRD)
Event announcement to industry – press release
Non-Disclosure Agreement (NDA)
Participant recruitment package
Letter of Invitation
Letter of Intent
Participant contract (Event Agreement)
Event execution documents, etc.
Tool requirements (scheduling, test data recording, reports)
Network and addressing plans
Requests for information from participants
Master test schedule
Pre-event briefing presentations
Implementation Agreements (IAs)
Test Plans
Other documents as needed

Event Testing
• Determine interfaces and functions to be tested
• Create physical architecture document
• Test plans written from 3GPP R8 specifications
by MSF member companies
• Protocol profiles written where required
• Labs and vendor equipment configured (1 week
set-up, 2 weeks testing, 1 week removal)
• Test results loaded into test tool by event
monitors – only test partners see results
• Patching/retesting if time permits
Copyright 2007: MultiService Forum
Event Wrap-up
• Create Press Release
• Analysis test data
• Write White Paper – test setup, results (all results
are non-attributable)
• Liaison appropriate SDOs regarding problems
found
• Lessons learned – all participants discuss what
went well and what could be done better
• Determine what event testing is to be carried
forward as well as candidates for future testing

EPC / LTE Interop Event White Paper
• A free download of the event white paper “MSF LTE
Interoperability Event – Multivendor testing in global
Evolved Packet Core Networks” is currently available:
http://www.msforum.org/interoperability/LTE.shtml
• The MSF work plan for 2010/2011 consist of 1) LTE/EPS
Phase 2 that builds on the recent LTE event success, 2)
MSF/ATIS IIF IPTV IOT, 3) Content Distribution Networks
(CDN) that builds on and broadens the IPTV work, 4)
Performance Testing and 5) Robustness testing across all
of the above mentioned areas.
