  1. GRX and Its Role in Inter-Standard Data Roaming Shu Gan VP Marketing, Aicent, Inc. CDG IRT, Macau March 2007

  2. Agenda • GPRS Roaming and GRX • GPRS vs. CDMA Data Roaming • Aicent GRX/CRX Enhance Inter-Standard Data Roaming

  3. DNS GGSN BTS PLMN BG SGSN PLMN PDN GPRS Roaming: How Does It Work? GTP Tunnel from SGSN to GGSN DNS SGSN IP Connectivity BTS BG GGSN PLMN: Public Land Mobile Network SGSN: Serving GPRS Support Node GGSN: GPRS Gateway Support Node

  5. APN SS7 (MAP) GRX GPRS Roaming – PLMN Roaming APN: Access Point Name (e.g. ibm.com.mcc123.mnc456.gprs) • GPRS Attachment or MS Registration – SGSN retrieves user data profile including APN from HLR via SS7 and registers the visited MS • PDP Context Activation – VSGSN establishes GTP tunnel with HGGSN; DNS is used to find home GGSN. • Bearer traffic goes though GRX through GTP Tunnel back to home.

  6. Agenda • GPRS Roaming and GRX • GRRS vs. CDMA Data Roaming • Aicent GRX/CRX Enhance Inter-Standard Data Roaming

  7. GRX and CRX Comparison

  8. Agenda • GPRS Roaming and GRX • GRRS vs. CDMA Data Roaming • Aicent GRX/CRX Enhance Inter-Standard Data Roaming (ISDR)

  9. Key Components for ISDR • Sponsor GPRS operator • Enable GPRS roaming relationship with visited GPRS network • IIF and AAA • Signaling/authentication integration • Home GGSN and Visited PDSN • Tunnel conversion for bearer traffic • Data Clearing • TAP and CIBER integration

  10. Two ISDR Cases • Third party ISDR total solution provider • Third party sponsor GPRS operator • Third party solution provider integrates IIF and AAA • Third party solution provider converts tunnels • Third party solution provider integrates TAP and CIBER • Self-sponsor ISDR • Self provides GPRS roaming agreements • Self provides IIF, GGSN and AAA • Self provides tunnel conversion • Self provides TAP billing system

  11. Sponsor GPRS IIF DNS DNS Root DNS ISDR Solution Concept in Case of MIP Home CDMA AAA HA AAA GGSN PDSN/FA CRX GRX Visited GPRS Proxy AAA SGSN BSC GTP Tunnel MIP/GRE Tunnel

  12. Sponsor GPRS IIF DNS Aicent Network Extends ISDR Provider’s Reach Home CDMA AAA HA AAA PDSN/FA Visited GPRS GGSN Proxy AAA Aicent GRX/CRX Network SGSN BSC GTP Tunnel MIP/GRE Tunnel

  13. Aicent GRX Network One of the largest global GRX providers • 50+ GPRS/3G operators in all major continents • 4 world’s largest GSM operators • 25 3G operators • 800+ million subscribers • 18 Peering arrangements • 300+ GPRS/3G networks reachable • 2500+ roaming commercial routes
