  1. Indoor/Outdoor Coverage Local Area Network Public Switched Telephone Network Outdoor Coverage Indoor Coverage Status: ICEBERG Testbed Motorola Paging Base Station ABISCO UPSim Ericsson BTS(1900 MHz) Proxy Proxy IPPad Ericsson Micro BTS (1800 MHz) Proxy H.323 Gateway

  2. Current IP-PAD RBS 2202 PCM-A PCM-B Diamux IP-PAD Ethernet ABISCO Ethernet

  3. Future IP-PAD Signaling 1900 MHz 1800 MHz RBS 2202 Micro-BTS PCM-A PCM-B ABISCO IP-PAD Ethernet Ethernet Traffic

  4. IPPAD • Generic PC + Thor-2 (ISA Card) + Software • Thor-2 has: • Two PCM links • IS Controller Chip • HDLC Controller allowing raw access to 8bit X 8KHz time slots

  5. Software • Passes 16Kbit sub-channel voice to VAT • Passes 16Kbit sub-channel data to RLP/UDP • Extracts 2 bits at a time from 8k time-slot • Finds frames • 4 Threads: • Read from UDP • Read from BTS • Write to BTS • Read Control

  6. Software • IP-PAD Code size is: • 2300 lines • 24K text • 528 byte initialized data • 12K DSS

  7. Software • RLP Code • Derived from Ericsson DCE software • XID handling not symmetric between IWF & Mobile • RLP code stats: • 30K text • 24K DSS • 4128 lines of code

  8. Internet Campus-wideGSMCoverage ICBERG & GSM on the Net Ericsson Lab Soda Hall Outdoor BTS (1800) BTS (1800) Signaling Gateway Abis Gateway Indoor BTS (1900) Jukebox IAP Access Node Appl. Node (IAP) GSM IAP IPPhone IAP VoicemailIAP PSTN IAP Service Node Firewall ICEBERG PoP

  9. GoN and ICEBERG • Interworking of GoN and ICEBERG testbed • Setup GoN in standalone mode • Implement IAP on GoN Application Node • Connect to testbed via Internet • Later: GPRS? • Location-Aware Applications • Second ICEBERG location at Ericsson enables development and test • Develop access to location information in GoN (using GoN API) • Possible synergy with Location API development • GSM Data Services for GoN • Migrate ICEBERG RLP implementation to GoN • Feedback experience and code into GoN product?

  10. IAP Requirement for GoN • Initiate calls • Receive calls • who from • dialed number • DTMF tones • IMSI attach and detach

  11. Future Work??? • Interaction between TCP-friendly congestion control and queuing • GoN: location dependent application • Service handoff via ICEBERG • Integrate 2nd location into testbed • GSM data services/RLP implementation • How to interwork
