GSM-R Issues for Continued Success 2002-01-25 GSM-R Issues for Continued Success Introduction RL, JK, LP From “getting ready....” to “... it’s all about execution” From plans in 2002 to visible action in 2003 ICM and ICN [Added business volume of ICM and ICN makes us comparable with the biggest competitors worldwide. Joint R&D spending in the same range compared with the main competitors. ICM and ICN have huge synergies in hardware and software, e.g. core platform of our switching solution. We work together to realize more and more of this synergies in the future (upside potential). SBS, ICM and ICN work closely via their corporate account management. We deliver solutions our customers need, including the necessary services.] Ola Bergman Siemens ICM templ-2-bo-example.ppt

The GSM-R Network Designed for Interoperability...with border crossing traffic GSM-R 21.8.03

GSM-R Interoperability Issues Inter-Operability Tests IOT – some background Common GSM-R Industry approach – first IOT meeting at Siemens in January 2002 Phases 1 and 2 – Basic Interoperability (including infrastructure and terminals from different vendors) verified, executed Nov-Dec 2002, report available Phase 3 – functions when crossing the border between two networks, planned for Winter 2003/2004 Phase 4 – mixed vendor configurations GSM-R 21.8.03

GSM-R Interoperability Issues IOT Phase 3.1 and 3.2 E-Interface Interoperability Test (switch to switch) VGCS and VBS with common, border-crossing Service Areas EIRENE network re-registration procedure IOT Phase 3.1 Siemens runs VGCS 11/2 channel Nortel runs VGCS 1 channel IOT Phase 3.2 Siemens runs VGCS 1 channel GSM-R 21.8.03

GSM-R Interoperability Issues IOT Phase 4.1 and 4.2 A-Interface Interoperability Test (switch to radio) All GSM features relevant for Railways All R-features IOT Phase 4.1 NSS from X, BSS from Y IOT Phase 4.2 NSS from Y, BSS from X GSM-R 21.8.03

GSM-R Interoperability Issues Full Interoperability to be proven 1st half 2004 Operational rules at border crossing Common Industry Interoperability Statement Railways require a certain freedom of choice Funding of IOT work Long term European concept for maintained Interoperability in an evolving environment GSM-R 21.8.03

GSM-R ETCS Issues GSM-R as platform for ETCS L2 Some still ongoing operational issues (border crossing) QoS parameter values to be settled Engineering for dense areas GSM-R 21.8.03

GSM-R Issues In summary… GSM-R in operational use Interoperability is Key GSM-R platform for ETCS L2 GSM-R 21.8.03

GSM-R… the Winner GSM - R the eal way R for ailways GSM-R 21.8.03
