[srslte-users] LTE, multiple default and multiple dedicated bearers

[Maksim M]

Hello,

As a given imsi could have multiple default bearers to the different APNs, I see that all those bearers will have the same GTP-C FTEID(UL/DL), at least on S11 interface. For me it's important to have separate entry for each default bearer in GTP-C Table as every APN has its own  PDN address. Following some capture, it looks like every default bearer(the case for multiple bearers for the subscriber) has its own default bearer_id, so we use GTP-C TEID plus default bearers_id to maintain record for the given APN.

But some records, like Create Bearer Response and  Delete/Release has no default bearer_id, thus could not be associated to GTP-C session. So my question how EPC handles those cases(multiple default and multiple dedicated bearers for the single imsi)


Thanks,
Maksim
