# IMEI Profile Configuration Mode

The IMEI profile configuration mode defines a set of parameters controlling the SGSN behavior when a Request is received from a device in the specified IMEI (International Mobile Equipment Identity) range. An IMEI profile is a key element in the Operator Policy feature and an IMEI profile is not used or valid unless it is associated with an IMEI range and this association is specified in an operator policy (see the Operator Policy Configuration Mode Commands chapter elsewhere in the Command Line Interface Reference).

Essentially, an IMEI profile is a template which groups a set of device-specific commands that may be applicable to one or more IMEIs. The same IMEI profile can be associated with multiple IMEI ranges and multiple operator policies.

An SGSN supports a total of 1000 IMEI profile configurations.
When this mode is accessed, the command prompt should resemble:

    [local]asr5000(imei-profile-<profile_name>)#

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
associate

Associate an APN remap table with this IMEI profile.

Note that an APN remap table can be associated with an IMEI profile before the table has actually been created/configured.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    associate apn-remap-table table_nameno associate apn-remap-table

no

Disables the configured remap table association.
table_name

Define the name of an APN remap table that is to be associated with this IMEI profile for call routing based in IMEI.
Usage:

Use this command to associate an APN remap table with this IMEI profile. With such an association, it is possible to override an APN call-routing based on an IMEI.

For example, with the APN exceptions defined in an APN remap table (refer to the APN Remap Table Configuration Mode chapter), a blank APN or an incorrect APN could be overriden. So during PDP Activation for in incoming call, the call could be rerouted based on an IMEI in the range defined for the IMEI profile.
Example:
Associate the APN remap table ‘remapHO’ (remaps all calls with blank APNS to the head-office) to this IMEI profile:

    associate apn-remap-table remapHO

blacklist

Blacklist all mobile devices that fit the IMEI definitions associated with this IMEI profile.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    blacklistremove blacklist

remove

Including this keyword with the command, removes the blacklist command from the IMEI profile configuration.
Usage:

Blacklists subscribers whose devices bear IMEI that match the defined IMEI range for this profile.

Example

Example
Use this command to black list all subscribers with IMEI that fall within the range set for this IMEI profile:

    blacklist

description

Define a descriptive string relevant to the specific APN profile.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    description descriptionremove description

remove

Removes the configured description from this APN profile.
description

Enter an alphanumeric string of 1 to 100 alphanumeric characters. The string may include spaces, punctuation, and case-sensitive letters if the string is enclosed in double quotes ( “ ).
Usage:

Define information that identifies this particularly APN profile.
Example:
Indicate that this IMEI profile IMEIprof1 is to be used for customers in the United Kingdom and that the profile:

    description “IMEIprof1 defines
    routing actions based on IMEI for customers in the UK.”

direct-tunnel

Instruct the SGSN to enable/disable a direct tunnel between the RNC and the GGSN based on the IuPS service configuration.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    direct-tunnel check-iups-serviceno direct-tunnel

no direct-tunnel

This command instructs the SGSN to disable the direct tunnel function between the GGSN and the RNC.
Usage:

Direct tunnel is enabled by default on the GGSN and often on the RNC. This leaves it to the SGSN’s configuration to actually enable or disable a direct tunnel.

With the SGSN, the options for configuring a direct tunnel are complex -- enable/disable on the basis of APNs, or RNCs, or GGSNs, or on the basis of the IMEI range. Refer to the SGSN Administration Guide for configuration details.
Example:
Assuming the IuPS service configuration has enabled DT for associated RNCs, then use this command to enable DT from the RNC to the GGSN associated with this IMEI profile:

    direct tunnel check-iups-service

end

Exits the current configuration mode and returns to the Exec mode.
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    end

Usage:

Return to the Exec mode.
exit

Exits the current configuration mode and returns to the context configuration mode.
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    exit

Usage:

Move to the previous configuration mode.
ggsn-address

Identify the target GGSN for traffic being managed by this IMEI profile.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    ggsn-address IPv4/IPv6_address

IPv4/IPv6_address

Enter the IP address of the target GGSN. Enter the address in either standard IPv4 dotted decimal format or in standard IPv6 colon notation format.
Usage:

Use this command to define the IP address of the target GGSN to be associated with this IMEI profile.
Example:

The following command identifes the address of the GGSN associated with this IMEI profile as 123.123.11.1

    ggsn-address 123.123.11.1
