Entering the above command sequence results in the following prompt:

[local]host_name(tai-mgmt-db)#

Syntax

Syntax Description

[ 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 Guidelines

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.

Creates a new custom TAI list, and/or enters the tai-cstm-list configuration mode.

Syntax

Syntax Description

tai-custom-list tac value [ -noconfirm ]

tac value

Specifies the Tracking Area Code portion of the TAI as an integer from 1 through 65535.

A maximum of 1000 Custom TAI Lists can be configured per TAI Management Database.

Usage Guidelines

Use this command to enter the Custom TAI List Configuration Mode for an existing object or for a newly defined object.

Prior to 17.0, the MME could have a tracking area in only one tracking area list (TAI List). Consequently, the tracking area list assigned to subscribers attaching from different TAIs will be same, even if the adjacency of these tracking areas is not same. This resulted in the MME getting TAUs even as subscribers moved to the adjacent area.

With this functionality, you can configure adjacency lists as TAI Lists, thus reducing the Tracking Area Updates (TAU) received by MME. This feature enables the MME to send configured customized TAI List in ATTACH_ACCEPT/TAU_ACCEPT when a request is received from the custom or border TAIs.

Entering this command results in the following prompt:

[local]hostname{tai-cstm-list}#

Custom TAI List Configuration Mode commands are defined in the LTE Custom TAI List Configuration Mode Commands chapter.

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.

Syntax

Syntax Description

[ 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 Guidelines

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.

Syntax

Syntax Description

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.

If the TAI management database/object is configured for daylight savings using this keyword, the daylight savings time adjustment is applied in these messages only if the system time is within a daylight savings period.

Usage Guidelines

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