Abstract
Enabling the exchange of connection parameters where a user equipment (UE) lacks a secret shared with the network (e.g. a server), such as key materials, and lacks a valid certificate. In some embodiments, the connection parameters may be exchanged via EAP messages. In certain aspects, and particularly with respect to emergency attach, a simplified protocol is used with limited overhead because the UE does not attempt to authenticate the network, and the network does not attempt to authenticate the UE.
