I had a discussion with Denis today about both FDN and BDN status. GSM SIM Card:(EFsst) In this case, FDN service status depends on the bits in EFsst and EFadn invalidation information.( invalidation information is part of the "Get RESPONSE" response data) EFsst - FDN is allocated and activated in the SIM: FDN is enabled - When EFadn is invalidated or not activated. FDN is disabled - When EFadn is validated. EFsst - FDN is not allocated or not activated in the SIM: FDN is disabled Note: This information can be found in the 3GPP 11.11 specification section 11.5.1. Paragraph starts with "FDN capability request". Invalidation information bits information can be found in the 3GPP 51.011 specification section 9.2.1(Response parameters/data in case of an EF:) and section 9.3 USIM Card:(EFust, EFest) In USIM case, FDN enabled/disabled dependents on the bits in the EFust and EFest. Let me know if something is unclear Thanks and Regards, jeevaka ___ ofono mailing list ofono@ofono.org http://lists.ofono.org/listinfo/ofono
Re: Handling of Fixed Dialing
Hi Jeevaka and Denis, and thanks for the comments. I checked the invalidated-flag of EFadn (from file status-byte of GET RESPONSE) and it actually changed according to FDN-enabling/disabling. But for some reason I didn't got any change in EFsst for FDN/ADN-services. Could it be a good idea to add also reading of EFadn in the SIM-initialization routine, check invalidated-flag, and make decision of continuing initialization routine based on that? The other issue was that selection of service table (SIM/USIM) based on EFphase. So SIM returns '3' in my tests. But the SIM-card seems to be of type SIM (not USIM), because I accessed some USIM-type elementary files (EFest, EFpbr) and those returned only error-codes. Like phase (3g) wouldn't actually be exactly the same thing than USIM-type. What about doing the next change in the SIM-init routine (not trusting to EFphase response when accessing the correct service tables): - read first EFest - if EFest-access gives a valid response, read EFust - if EFest-access doesn't give a valid response, read EFsst Br, Petteri > > I had a discussion with Denis today about both FDN and BDN status. > > GSM SIM Card:(EFsst) > > In this case, FDN service status depends on the bits in EFsst and > EFadn invalidation information.( invalidation information is part of the > "Get RESPONSE" response data) > > EFsst - FDN is allocated and activated in the SIM: > > FDN is enabled - When EFadn is invalidated or not activated. > FDN is disabled - When EFadn is validated. > > EFsst - FDN is not allocated or not activated in the SIM: > FDN is disabled > > Note: This information can be found in the 3GPP 11.11 specification > section 11.5.1.

Exactly, thats what the specification also says. EFsst will inform 2 things: SIM's capabilty to support the service and service's availability for the card holder. EFadn's file status is the one we need to depend on for FDN enabled/disabled status. > The other issue was that selection of service table (SIM/USIM) based on EFphase. So SIM returns '3' in my tests.

In most of the message based modems(eg: isimodem), there exists a mechanism to get the type of the card. AT based modem is the issue. Since most of the AT based modems doesn't support AT+CSIM, its difficult to determine the card type. I still believe that we need to determine the card type during the SIM initialization itself for reading the right SIM files.
