Company Confidential 1© Nokia Siemens Networks / Multivendor Interoperability Introduction, Interoperability Verification at Nokia Siemens Janos Arrakoski, Nokia Siemens Networks, IOT Helmut Schink, Nokia Siemens Networks, Industry Environment Nairobi, July 30, 2010
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential Content Basis for Interoperability Interoperability Verification requirements are different Drivers for Interoperability Interoperability Verification at Nokia Siemens Networks Interoperability Verification Output/Benefit (for developing countries) Interoperability Verification Projects Experiences from developing countries Two Categories of Interoperability Issues Summary
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential Basis for Interoperability Open Standards and Conformance make multivendor configurations possible Conformance, compliance with standards is essential for interoperability, but; – No standard is perfect – Standards evolve – Implementations are different – Implementations evolve Although Standards and Conformance are in general good, some Interoperability challenges will exist in telecommunication networks due to the complexity of the systems Interoperability Verification is needed to identify those challenges
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential Interoperability Verification requirements are different Different Interoperability Verification activities and approaches are needed to address the various needs efficiently All stakeholders must participate and do their share Majority of networks where NSN is a supplier are multivendor networks and its also in NSN interest to endorse interoperability Interoperability Verification needs vary; Standards/Interface maturity and evolution, the complexity,… Deployment scenario and configuration … There are usually numerous possible multivendor configurations Different Vendor/Product/Interface/SW Version/Configuration & Parameter combinations
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential Drivers for Interoperability Interoperability is driven by market requirements, Operators demand: Supplier independency and competition Manage and minimize risks and costs,… State of art products Latest Functionality & features, Early Timing, High Quality, Low Cost,… Secure investment Product Evolution, Long lifecycle, Maintenance,… Consolidation and convergence Fixed/mobile, all IP,… Everything and Anything Seeking for Competitive Advantage
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential Interoperability Verification at Nokia Siemens Networks Interoperability Verification is a integrated part of the Nokia Siemens Networks Product Development process: – Driven by Technical requirements Market requirements Interoperability Verification is additionally supported and offered in the in the Product Delivery process: – Driven by Market requirements Other infrastructure manufacturers have the very same approach
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential Interoperability Verification Output/Benefit (for developing countries) All parties (Vendors and Operators in both developing and developed countries) benefit from the performed Interoperability Verification equally Products with improved interoperability become available to all Operators Results of Interoperability Verification are available to Operators for their multivendor configurations Operators striving for Technology Leadership trigger and participate in early Interoperability Verification (usually developed countries) Certain well proven configurations will arise Other operators (e.g. in developing countries) will benefit from that
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential Interoperability Verification Projects Experiences from developing countries Multivendor verification project duration is usually one to some weeks per interface depending on interface and test scope No blocking issues have been reported – Interoperability, conformity and standards are good Configuring the network is a key activity in the project – A task that must be done in every project anyway No differences compared to projects in developed countries Nokia Siemens Networks has run several successful multivendor projects in developing countries; Nigeria, South Africa, Tanzania,… Projects cover infrastructure for several technologies, GSM/GPRS, WCDMA and for both Core Network and Radio Network Elements
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential 1) Problems appearing as interoperability issues (i.e. occur in single vendor environment too) Many times wrongly perceived as interoperability issues, typically due to: Invalid Configuration of network Inadequate System Testing (Conformance, Functionality, Performance,…) Two Categories of Interoperability Issues Category 1) represent many times majority of issues in a multivendor project resulting in a false perception that interoperability is poor. The correct conclusion is in many cases: – System not properly configured and parameterized and/or Product Quality is poor 2) Real interoperability issues (i.e. occur only multivendor environment) Protocol conformance is usually high, issues arise mostly due to: Different options allowed by specifications Incomplete and/or ambiguous specifications Invalid Configuration of network
2009© Nokia Siemens Networks NSN Multivendor Interoperability Presentation for ITU-T / JAr / Customer Confidential Summary Market driven Interoperability Verification is efficient and focus on operator needs A mechanism to address potential interoperability issues is already in place Final configuration and parameterization of the operator network must always be done in the operator network Open Standards and Conformance alone will not ensure 100% interoperability Standards are widely available and adopted Conformance is mostly at a good level Each Vendor define and ensure their conformance
