Syntax Description

[ no ] emergency-services-not-supported

no

For the emergency-services-not-supported command, the no command prefix enables emergency services at TAI management object level.

Usage Guidelines

In a shared RAN network, there are several TACs contolled by several operators connected to the same MME, and disabling emergency services for a particular TAC becomes a challenge. To over come this, MME provides the emergency-services-not-supported command, which disables emergency services at a TAI management object level per TAC basis.

no

Disables support for IMS Voice over PS for this TAI List.

Usage Guidelines

Use this command to enable support for IMS Voice over PS for this TAI List.

When enabled, the IMS Voice Over PS Indicator is sent in the S6a Insert-Subscriber-Data Answer message. This indicates whether the TAI supports 'IMS Voice over PS session'.

If IMS Voice over PS support is configured globally within the Call Control Profile (using the network-feature-support-ie ims-voice-over-ps command) as well as on a per TAI basis, the global configuration (from call control profile) is honored.

Syntax

Syntax Description

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

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.

Usage Guidelines

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.

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 Guidelines

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:

This command specifies the address resolution mode of the SGW address(s) configured in this object. This command is applicable only for S4-SGSN.

Default: enabled

local

Instructs the system to only use locally configured S-GW addresses and not to use DNS query.

Default: disabled

Usage Guidelines

Use this command to specify the DNS query or local address resolution for this LTE TAI Management Object. The addresses will be valid only for lac and rac defined under tai-mgmt-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.

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.

zc_id

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

Usage Guidelines

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.
