Hi,
As per the 3GPP 22.030 Annex C:
- the MMI Service Code "22" refers to "All sync services"
telecommunication service.
- the MMI Service Code "24" refers to "All data circuit sync"
telecommunication service.
They are both linked to the same Basic Group Service 8.
So as per our understanding, this means the "All sync services" is equal to
"All data circuit sync". Is that everyone's comprehension as well?
When we try to run Call Barring certification tests (particularly 31.8.3.1 from 3GPP
51.010), the spec requires us to activate the call barring with the MMI code
"22".
We do it using org.ofono.SupplementaryServices.Initiate with the following string
"*33*1234*22#" (This is the activation of BAOC with password "1234" on
All Sync Services), Ofono then sends to the modem the following AT command:
AT+CLCK="AO",1,"1234",16
According to the 3GPP 27.007 §7.4 (CLCK), 16 is "data circuit sync".
So modem will translate that into "all data circuit sync" in the REGISTER
message sent to the network simulator.
However according to 3GPP 51.010 31.8.3.1, only a REGISTER message containing "All
synchronous services" is awaited. So conformance scripts will consider the test as
FAILED.
We noticed the test would be PASS only if CLCK classx parameter was 80 (instead of 16). 80
= 16 (data circuit sync) + 64 (dedicated packet access).
Shouldn't we translate the "*33*1234*22#" MMI SS String into
AT+CLCK="AO",1,"1234",80 ?
Regards
Fred
