How MB service can update MB profile when APN changed in the MB device?

Hi, I have some questions about?how to sync profile information
between MB service and MB device.

I have a MB miniport and MB device running on Windows 7. And I need to
find a solution on how to sync profile information between MB device
and MB service. If I change the profile (say changing the APN) in the
MB device through AT command or OTA, the firmware will send up an
indication about?this profile change?to my miniport driver. Then
miniport driver can shoot an unsolicited
NDIS_STATUS_WWAN_PROVISIONED_CONTEXTS notification event to the MB
service with the updated list. My question at here is after MB service
receives this notification, will MB service update the APN in the MB
profile so that I can see the new APN in the VAN UI?

Another question is if the user changes APN through VAN UI, according
to my current test and debug, MB service will not send down set
OID_WWAN_PROVISIONED_CONTESTS to the MB miniport driver. Is there any
way I can trigger MB service sending down the set
OID_WWAN_PROVISIONED_CONTESTS to my miniport driver so that I can
update the APN in the MB device?

Thanks.

Well, usually there is a “single point of update” in such cases.

If the OS has an OS-provided way of doing this - then go this way, and usually the attempts to do the same in a low-level way (like a direct AT command) are deliberately left out of sync with the proper way.

Thanks Maxim. Can you explain a little bit more details? And if my
miniport driver sends up the unsolicited
NDIS_STATUS_WWAN_PROVISIONED_CONTEXTS notification event to the MB
service with the updated list, MB service will update the MB profile
with the new APN? Thanks again.
