1. 1 Schlumberger Implementation of SIM Toolkit in the CDMA SIM Kamilla Gam Nielsen Schlumberger Technologies (Europe) International Implementation of SIM Toolkit in the CDMA SIM Kamilla Gam Nielsen Schlumberger Technologies (Europe) International

2. 2 Schlumberger The SIM needs to know which network it is in Handling the conversion of the CDMA SMS / SMSPP USSD and SS in CDMA networks are they supported ? Setup Call number format is different between CDMA and GSM The UCS2 support only mentioned in the IS-820 GSM and CDMA differences General issues regarding STK in CDMA SIM

3. 3 Schlumberger Scenarios of CDMA STK The different scenarios: The SIM and ME in the GSM network The SIM and ME in the CDMA network The SIM does the SMS conversion The ME does the SMS conversion The SIM is receiving SMS/SMSPP messages The SIM is sending SMS messages

4. 4 Schlumberger The SIM and ME in the GSM network SIM = RUIM and ME = Phase 2+ GSM: Receiving and sending SMS/SMSPP, no conversion Handset and SIM communicating as per GSM protocol standards GSM SMS Service Center  

5. 5 Schlumberger The SIM and ME in the CDMA network SIM = RUIM and ME = CDMA with SIM slot How to manage the STK protocol between SIM and ME Details like the handling of two sets of SMS Storage areas on the card ? ?

6. 6 Schlumberger If SIM handles the conversion Receiving SMS-PP Code size increases due to dual SMSPP handling Performance of the SIM conversion 04 03 81 21 F3 7F F6 05 32 31 32 31 31 SMSPP download SMSPP GSMCDMA SIM Toolkit Conversion

7. 7 Schlumberger If SIM handles the conversion Receiving SMSPP ME has to recognize a SMSPP ME has to forward SMSPP transparently to SIM SIM has to understand / convert the CDMA SMSPP (header and body content) CDMA SMS Service Center ??

8. 8 Schlumberger The SIM and ME in the CDMA network ME handles the conversion: SIM will function as it does right now, seeing the network as GSM ME has to convert and forward information to both SIM and Network CDMA SMS Service Center ? 
