# LTE TAI Management Database Configuration Mode Commands

The LTE TAI Management Database Configuration Mode is used to create and manage the LTE Tracking Area Identifier (TAI) management database configuration for LTE polices configured on this system.

IMPORTANT:

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

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

All
Privilege:

Security Administrator, Administrator
Syntax

    end

Usage:

Use this command to return to the Exec mode.
exit

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

All
Privilege:

Security Administrator, Administrator
Syntax

    exit

Usage:

Use this command to return to the parent configuration mode.
network-name

This command configures the long (full) and short network name used in the Long and Short network name IE in the EMM Information message that is sent to the UE from the MME.
Platform:

ASR 5000
Product:

MME
Privilege:

Administrator
Syntax

    [ no ] network-name [ full full_name | short short_name ]

no

Removes a configured network-name.
full full_name

Defines the full (long) network name. full_name is an alphanumeric string of 1 through 251 characters.
short short_name

Defines the short network name. short_name is an alphanumeric string of 1 through 251 characters.
Usage:

Use this command to configure the full and short network name on the tai-db object.

This configuration affects the actions of the MME when the MME is configured to set the UE time. If this configuration exists, and there is no interaction with an MSC that sends a EMM INFORMATION message, the MME uses the above configuration while sending an EMM INFORMATION message.

There is no default for this configuration. If this configuration does not exist at the tai-db level and tai-mgmt-object level, no network name will be signaled in a EMM Information message.
tai-mgmt-obj

Creates new, or removes/enters existing, LTE Tracking Area Identifier (TAI) object configurations. On the S4-SGSN, this command is required as part of configuring S-GWs and their associated RAIs to bypass DNS resolution of RAI FQDN for obtaining the S-GW address.
Platform:

ASR 5000
Product:

MME, SGSN
Privilege:

Administrator
Syntax

    [ no ] tai-mgmt-obj object_name [ -noconfirm ]

no

Removes a configured TAI management object from the TAI management database.
-noconfirm

Executes the command without any additional prompt and confirmation from the user.
object_name

Specifies the name of the TAI management object and enters the LTE TAI Management Object Configuration Mode as an alphanumeric string of 1 through 64 characters.
Usage:

Use this command to enter the LTE TAI Management Object Configuration Mode for an existing object or for a newly defined object. This command is also used to remove an existing object.

On the S4-SGSN, after creating the TAI Management Object and entering TAI Management Object Configuration Mode, the rai and sgw-address commands are used to complete the S-GW for RAI configuration. Refer to the LTE TAI Management Object Configuration mode chapter for details on these commands.

Entering this command results in the following prompt:

    [context_name]hostname(tai-mgmt-obj)#

LTE TAI Management Object Configuration Mode commands are defined in the LTE TAI Management Object Configuration Mode Commands chapter.
Example:
The following command creates a TAI management object called tai-obj3 and enters the LTE TAI Management Object Configuration Mode:

    tai-mgmt-obj tai-obj3

timezone

Configures the timezone to be used for the UE timezone in S11 and Non Access Stratum (NAS) messages.
Platform:

ASR 5000
Product:

MME
Privilege:

Administrator
Syntax

    timezone { + | - } hours value [ minutes { 0 | 15 | 30 | 45 } | daylight-savings-time-increment { 0 | 1 | 2 } ]no timezone

Removes the timezone configuration from the management database.
+ | -

Specifies the offset direction from the Coordinated Universal Time (UTC).
hours value

Specifies the offset from UTC in hours. value must be an integer from 0 through 14.
minutes { 0 | 15 | 30 | 45 }

Optionally specifies the offset minutes added to the hours value.
daylight-savings-time-increment { 0 | 1 | 2 }

Specifies the number of hours the timezone should be offset due to daylight savings time. This allows the MME to serve areas that have daylight savings time different than that of the MME. This keyword is available in release 14.0 and higher.
Usage:

Use this command to configure the timezone to be used for the UE timezone in S11 and NAS messages.

IMPORTANT:

Time zone configurations at the TAI Management Object level take precedence over time zone configurations at the TAI Management Database level. If neither is configured, the system defaults to the MME time zone.
Example:
The following command sets the timezone mapping for this management database to plus-3 hours and 15 minutes from UTC:

    timezone + hours
    3 minutes 15
