EXCEPTION: Steps 13a1 to 13c1 describe behaviour that depends on UE capabilities; the "lower case letter" identifies a step sequence that take place depending on whether the UE is configured for S1_U_DataTransfer and if not then if it is configured to do Attach Without PDN or not.

13a1

IF S1_U_DataTransfer THEN the SS transmits a RRCConnectionReconfiguration-NB message to establish the default bearer with condition DRB(1) according to [8.1.8].

This message includes the ATTACH ACCEPT message and the ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST message is piggybacked in the ATTACH ACCEPT.
