Values: <cid> PDP Context Identifier

Range: 1-4

Integer type

<PDP_type> Packet Data Protocol Type

"IP" Internet Protocol

"PPP" Point to Point Protocol

<APN> Access Point Name: A logical name that is used to select the GGSN or the

external packet data network.

String type

If the value is null or omitted, then the subscription value will be requested.

<PDP_addr> PDP Address: Identifies the modem in the address space applicable to the

PDP.

If the value is null or omitted, then a value may be provided by the DTE during

the PDP startup procedure or a dynamic address will be requested.

The read form of the command will continue to return the null string even if an

address has been allocated during the PDP startup procedure. The allocated

address may be read using the +CGPADDR command. String type.

<d_comp> PDP Data Compression Mode

0 Off. Default

1 On

<h_comp> PDP Header Compression

0 Off. Default

1 On

Parameter Storage: The parameters are stored in EEPROM without

using AT&W.

Examples:

Command Responses

AT+CGDCONT=? +CGCONT: (1-4), “IP”,,,(0-1),(0-1)

+CGCONT: (1-4), “PPP”,,,0,0

AT+CGDCONT: 1, “IP”

“internet”

AT+CGCONT? +CGCONT: 1, “IP”,”internet”,,0,0

AT+CGDCONT=1

Note: Delete <cid>=1

AT+CGDCONT? OK

+CGEQMIN 3G Quality of Service Profile (Minimum Acceptable)

Description: The test command returns values supported as a compound value.

The read command returns the current settings for each defined context for which a

QOS was explicitly specified.

The write command allows the TE to specify a Quality of Service Profile for the context

identified by the (local) context identification parameter <cid> which is checked by the

MT against the negotiated profile returned in the Activate/Modify PDP Context Accept

message. A special form of the write command, AT+CGEQMIN=<cid> causes the

requested profile for context number <cid> to become undefined.

Syntax:

Test Command: AT+CGEQMIN=?

Test Response: +CGEQMIN: <PDP_type>, (list of supported <Traffic class>s), (list of supported

<Maximum bitrate UL>s), (list of supported <Maximum bitrate DL>s),

1 2 ... 85 86 87 88 89 90 91 92 93 94 95 ... 146 147
