Introduction ■ Most CDMA operators(SKT, CU, KDDI, TMNZL, Hutch CAT, APBW) had agreed to provide SMS MO in int’l roaming environment at last Bangkok meeting ■ In the CDMA world we currently do not have any survey that int’l SMS MO’s impact on int’l roaming revenue but we believe that int’l SMS MO is really needed for customers from the marketing point of view

  8. Implementation Issues

  9. Implementation Issues ■ How does serving network route SMDPP to home network? - So far most operators (SKT, TMNZL, CU, Hutch CAT, APBW) support Indirect SMS routing so they can route SMDPP based on calling number (IRM) - SMDPP will be routed to TSI and TSI will work as a SMS facilitator - Serving network should fully support MIN/MDN separation to avoid number conflict (IRM and local numbering plan)

  10. Implementation Issues ■ Which parameter does your MC expect as a final terminating address? - So far most operators’(TMNZL, CU, Hucth CAT, APBW) MC expects SMS_ODA - SKT MC expect SMS_DA

  11. Implementation Issues ■ Which value does your MSC and MC send and expect in SMDPP? - SMDPP from MSC - SMDPP to MC

  12. Implementation Issues ■ How can operators charge Int’l SMS MO? - Basically SMS CDR is generating in not MSC but MC so home operators can charge their subscribers - For roaming rate and settlement we can use TSI report ■ Others - MIN-MDN value conversion in TSI - MDN parameter insert in TSI

  13. Action Items
