Table 10.1.31-1: +CGAUTH parameter command syntax

Command	Possible response(s)
+CGAUTH=<cid>[,<auth_prot>[,<userid>[,<password>]]]	+CME ERROR: <err>
+CGAUTH?	[+CGAUTH: <cid>,<auth_prot>[,<userid>,<password>],[<DN_id>] [<CR><LF>+CGAUTH: <cid>,<auth_prot>,<userid>,<password>],[<DN_id>] […]]]
+CGAUTH=?	+CGAUTH: (range of supported <cid>s),(list of supported <auth_prot>s),(length of supported <userid>s),( length of supported <password>s)

Description

Set command allows the TE to specify authentication parameters for a PDP context identified by the (local) context identification parameter <cid> used during the PDP context activation and the PDP context modification procedures. Since the <cid> is the same parameter that is used in the +CGDCONT and +CGDSCONT commands, +CGAUTH is effectively as an extension to these commands. Refer clause 9.2 for possible <err> values.

A special form of the set command, +CGAUTH=<cid> causes the authentication parameters for context number <cid> to become undefined.

The read command returns the current settings for each defined context.

The test command returns values supported as compound values.

Defined values

<cid>: integer type. Specifies a particular PDP context definition (see the +CGDCONT and +CGDSCONT commands).

<auth_prot>: integer type. Authentication protocol used for this PDP context.

0 None. Used to indicate that no authentication protocol is used for this PDP context. Username and password are removed if previously specified.

1 PAP

2 CHAP

3 DN authentication (EAP authentication)

<userid>: String type. User name for access to the IP network.

<password>: String type. Password for access to the IP network.

<DN_id>: string type in UTF-8, indicates a DN-specific identity of the UE in the network access identifier (NAI) format according to IETF RFC 7542 [37], encoded as UTF-8 string, see 3GPP TS 24.501 [161], section 9.11.4.15.

Implementation

Optional.
