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

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
