Hi everyone,
I see that current work to support multi SIM goes from lower layers to upper
layers covering the main SIM features, but at a low level I don't see how can
be mapped each SIM with a data connection.
For example, the network stats service obtains data usage values by checking
the amount of data transmited per each network interface, the network manager
notifies the network stats service when a network interface is registered and
gives information about the kind of connection (mobile or wifi). With multi SIM
we can have more than one mobile connection, so I can't figure how to map
different mobile connections to a diferent SIMs.
After looking the new RIL multi SIM architecture with multiples
MSimInterfaceLayers I assume that each SIM will have a different network
interface assigned: rmnet0, rmnet1 and so on. Am I wrong?
Yes, I believe each SIM has a different network interface.
If each SIM can be related with one network interface, at least when two SIMs
can work at the same time, how can be related the iccInfo object with the
underlying network interface?
For the multi-SIM support, we plan to expose 'serviceId' in
NetworkInterface [1]. Network stats service will know the 'service id'
which the register/unregister event is generated for. And you can get
more detailed information about this service, for example iccId, through
mobileConnection API.
var iccId = navigator.mozMobileConnection[serviceId].iccId;
I think that it will also affect to tethering functionality, because the user
will want to be able to configure which SIM card exposes the shared connection.
Good point, I think we should pass 'serviceId' for the case that user
want to configure a specific SIM card as a shared connection.
Regards,
Albert
