Identify PDP context by RAB ID, not TEI
When receiving an RAB-Assignment response from the RNC, we should use the RAB ID (=NSAPI) to resolve the PDP context. We cannot use the TEID, as the TEID chosen by the RNC for this RAB has no relationship to the TEID we were using for the RAB-Assignment request. TEIDs are local to each of the peer, like UDP port numbers.
