Privilege:

Administrator
Syntax

    lai mcc number  mnc number lac area_codeno lai

no

Removes a configured LAI from the TAI management object.
mcc number

Specifies the mobile country code (MCC) portion of a PLMN identifier as an integer from 100 through 999.
mnc number

Specifies the mobile network code (MNC) portion of a PLMN identifier as a 2- or 3-digit integer from 00 through 999.
lac area_code

Specifies the Location Area Code portion of the TAI as an integer from 1 through 65535.
Usage:

Use this command to configure an LAI for this management object.
Example:

    lai mcc 122 mnc 22
    lac 101

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-mgmt-obj.

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 an EMM INFORMATION message, the MME uses the above configuration while sending a 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.
rai

Configures a Routing Area Identifier (RAI) for an associated S-GW for this TAI management object.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Administrator
Syntax

    rai mcc number  mnc number lac area_coderacrac_valueno rai

no

Removes a configured LAI from the TAI management object.
mcc number

Specifies the mobile country code (MCC) portion of a PLMN identifier as an integer from 100 through 999.
mnc number

lac area_code

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

rac

Specifies the Routing Area Code portion of the TAI as an integer from 1 to 255.
Usage:

On the S4-SGSN, use this command as part of the configuration of the selection of an SGW for RAI on the S4-SGSN for operators wishing to bypass the DNS resolution of RAI FQDN for obtaining the SGW address.

Once the RAI is configured, the SGW address that serves this RAI must be configured with the sgw-address command. For details on this command, refer to the description of sgw-address in this chapter.
Example:
The following command adds a RAI to this management object with an MCC of 111, an MNC of 22, and a LAC of 110:

    rai mcc 111 mnc 22
    lac 101 rac 110

Product:

MME, SGSN
Privilege:

Administrator
Syntax

    sgw-address ipv4_or_ipv6_address s5-s8-protocol { both | gtp | pmip } weight numberno sgw-address ipv4_or_ipv6_address s5-s8-protocol { both | gtp | pmip }

no sgw-address ipv4_or_ipv6_address s5-s8-protocol { both | gtp | pmip }

Removes the configured S-GW address from this TAI management object.
ipv4_or_ipv6_address

Specifies the IP address of the S-GW in the selection pool in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation.

Up to 32 S-GW addresses can be configured per TAI management object.
s5-s8-protocol { both | gtp | pmip }

Specifies the S5/S8 interface type found between the configured S-GW and the P-GW.

both: Specifies that both the GTP and PMIP protocols are supported over the S5/S8 interface. The both option is not supported on the SGSN.

gtp: Specifies that the GTP protocol is supported over the S5/S8 interface. This is the only option supported by the SGSN.

pmip: Specifies that the PMIP protocol is supported over the S5/S8 interface. The pmip option is not supported on the SGSN.
weight number

Specifies the priority or weight of the S-GW address used during weighted round-robin selection within this TAI management object. number must be an integer from 1 through 100.
Usage:

Use this command to configure a pool of S-GW addresses used for S-GW selection.

On the S4-SGSN, use this command to complete the configuration of bypassing DNS resolution of RAI FQDN to obtain the S-GW address. This command is not valid on the S4-SGSN until the following commands have been executed:

- tai-mgmt-db in LTE Policy Configuration Mode
- tai-mgmt-obj in LTE Management Database Configuration Mode
- rai in LTE TAI Management Object Configuration Mode

Example:
The following command configures an S-GW with an IPv4 address of 10.2.3.4, a supported S5/S8 protocol type of GTP, and a selection weight of 3:

    sgw-address 10.2.3.4
    s5-s8-protocol gtp weight 3

tai

Configures a Tracking Area Identifier (TAI) for this TAI management object.
Platform:

ASR 5000
Product:

MME
Privilege:

Administrator
Syntax

    [ no ] tai
    mcc number  mnc number { tac value } +

no

Removes a configured TAI from the TAI management object.
mcc number

Specifies the mobile country code (MCC) portion of a PLMN identifier as an integer from 100 through 999.
mnc number

Specifies the mobile network code (MNC) portion of a PLMN identifier as a 2- or 3-digit integer from 00 through 999.
tac value +

Specifies the Tracking Area Code portion of the TAI as an integer from 1 through 65535. Up to 16 TAC values can be entered on a single line.
Usage:

Use this command to configure one or more TAIs for this management object. Up to 16 TAIs can be configured per management object.
Example:
The following command adds a TAI to this management object with an MCC of 111, an MNC of 22, and a TAC value of 1001:

    tai mcc 122 mnc 22
    tac 1001

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 object.
+ | -

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

Specifies the offset from UTC in hours as 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 object to plus-3 hours and 15 minutes from UTC:

    timezone + hours
    3 minutes 15

zone-code

Configures a zone code for the management object.
Platform:

ASR 5000
Product:

MME
Privilege:

Administrator
Syntax

    zone-code zc_id

    no zone-code

no

Removes the configured zone-code from the management object.
zc_id

Identifies the zone code configuration instance as an integer from 1 through 65535.
Usage:

IMPORTANT:

While there is no limit to the number of zone codes that can be created, only 10 LACs per zone code can be defined.

Use this command to define zone code restrictions. Regional subscription data at the home subscriber service (HSS) is used to determine the regional subscription area in which the subscriber is allowed to roam. The regional subscription data consists of a list of zone codes which are comprised of one or more location areas (identified by a LAC) into which the subscriber is allowed to roam. Regional subscription data, if present in the Insert-Subscriber-Data-Request (IDR) and the Update-Location-Answer (ULA) from the HSS, defines the subscriber's subscription area for the addressed MME. It contains the complete list (up to 10 zone codes) that apply to a subscriber in the currently visited PLMN. During the Location Update procedure, the zone code list is received in the ULA from the HSS. The zone code list is validated against the configured values in this command. If matched, the Location Update procedure is allowed to proceed. If not matched, the response is that the Network Node Area is restricted and the Location Update procedure fails.
Example:
The following command sets the zone code for this management object to 1:

    zone-code 1
