Command	Possible response(s)

Description

The set command controls the presentation of an unsolicited result code +C5GPDUAUTHU: <cid>, <len>, <eap_msg> which will be displayed on receiving an authentication message in the form of Extensible Authentication Protocol (EAP) message from network during or after a UE-requested non-emergency PDU establishment request has been sent. The purpose of the PDU session authentication and authorization is to enable the data network (DN) to authenticate and authorize the upper layers of UE. This procedure happens through EAP as specified in IETF RFC 3748 [32] and 3GPP TS 24.501 [161] clause 6.3.1.

There can be several sessions of exchange of an EAP-request and EAP-response message for the DN to complete the authentication and authorization of the request for a PDU session. The network shall start a timer (T3590) once the EAP-request message has been sent and expects the EAP-response message from UE to stop the timer. On expiry of the timer, network shall re-transmit the message after restarting the timer. This can be retransmitted for four times.

Read command returns the current setting of value <n>.

Test command returns the range of supported <n>.

Defined values

<n>: integer type. Enables or disables reporting of authentication indication from network consisting of the EAP-message for a particular <cid>.

0 disable reporting.

1 enable reporting.

<cid>: integer type, specifies a particular QoS flow definition (see the +CGDCONT and +CGDSCONT commands).

<len>: integer type, indicates the length of the EAP message content. It can be of max 1500 according to 3GPP TS 24.501 [161] clause 9.11.2.2.

<eap_msg>: string type in hexadecimal format, consists of the EAP message from network, as defined in IETF RFC 3748 , IETF RFC 4187 and IETF RFC 5448. This parameter shall not be subject to conventional character conversion as per +CSCS.

Implementation

Optional.
