+CGDCONT - Define PDP Context

AT+CGDCONT=

[<cid>

[,<PDP_type>

[,<APN>

[,<PDP_addr>

[,<d_comp>

[,<h_comp>

[,<pd1>

[,…[,pdN]]]]]]]]]

Set command specifies PDP context parameter values for a PDP context

identified by the (local) context identification parameter, <cid>

Parameters:

<cid> - (PDP Context Identifier) numeric parameter which specifies a

particular PDP context definition.

1..

max

- where the value of

max

is returned by the Test command

<PDP_type> - (Packet Data Protocol type) a string parameter which

specifies the type of packet data protocol

"IP" - Internet Protocol

"PPP" - Point to Point Protocol

“IPV6” - Internet Protocol, Version 6

<APN> - (Access Point Name) a string parameter which is a logical name

that is used to select the GGSN or the external packet data

network. If the value is null or omitted, then the subscription value

will be requested.

<PDP_addr> - a string parameter that identifies the terminal in the address

space applicable to the PDP. The allocated address may be

read using the +CGPADDR command.

<d_comp> - numeric parameter that controls PDP data compression

0 - off (default if value is omitted)

1 – on

2 - V.42bis

<h_comp> - numeric parameter that controls PDP header compression

0 - off (default if value is omitted)

1 – on

2 - RFC1144 (applicable for SNDCP only)

3- RFC2507

4- RFC3095 (applicable for PDCP only)

<pd1>, …, <pdN> - zero to N string parameters whose meanings are

specific to the <PDP_type>

Note: a special form of the Set command, +CGDCONT=<cid>, causes the

values for context number <cid> to become undefined.

AT+CGDCONT? Read command returns the current settings for each defined context in the

format:

+CGDCONT: <cid>,<PDP_type>,<APN>,<PDP_addr>,<d_comp>,

<h_comp>[,<pd1>[,…[,pdN]]][<CR><LF>+CGDCONT: <cid>,

<PDP_type>,<APN>,<PDP_addr>,<d_comp>,<h_comp>

[,<pd1>[,…[,pdN]]][…]]

AT+CGDCONT=? Test command returns values supported as a compound value

Example AT+CGDCONT=1,”IP”,

”APN”

,”10.10.10.10”,0,0
