Syntax Description

associate { diameter { dictionary standard | endpoint endpoint_name } | map-service map_svc_name | sls-service sls_svc_name  }
default associate diameter dictionary 
no associate { diameter endpoint | map-service | sls-service }

default

Returns the command to its default value of 'standard'.

no

Disassociates a previously associated interface or service with this location service.

diameter dictionary standard

Associates a Diameter dictionary with this location service. The standard dictionary contains definitions per the 3GPP definition.

diameter endpoint endpoint_name

Specifies the Diameter endpoint for this location service, which includes the hostname, peer configuration, and other Diameter base configuration.

map-service map_svc_name

Associates a Mobile Application Part (MAP) service with this location service.

This keyword is applicable for SGSN only.

map_sv_svc_name specifies the name for a pre-configured MAP service to associate with this location service.

sls-service sls_svc_name

Associates an SLs service with this location service. The SLs service provides an interface between the MME and Evolved Serving Mobile Location Center (E-SMLC).

This keyword is applicable for MME only.

sls_svc_name specifies the name for a pre-configured SLs service to associate with this location service.

Usage Guidelines

Use this command to specify the Diameter dictionary and endpoint to be used for this location service, or associate supportive services with this location service.

The location service provides SLg (MME) interface support or Lg (SGSN) interface support via the Diameter protocol between the MME or SGSN and the GLMC.

Configures the host name of the GLMC to be used for this Location service. When defined, this host name is populated in the destination-host AVP.

Syntax

Syntax Description

destination-host destination_host
no destination-host

no

Removes the configured destination host.

destination_host

Defines the host name to be used, as an alphanumeric string from 1 to 63 characters.

Usage Guidelines

To comply with 3GPP TS29.172, the Destination-Host AVP is sent to the GMLC for all the Location Report Request (LRR) messages initiated by MME.

Use this command to configure the destination-host AVP for this Location service.

If this command is not configured, the peer host name configured in the diameter endpoint is encoded as Destination-Host AVP. Refer to the peer command in the Diameter Endpoint Configuration Mode.

Controls the Subscriber Location Report (SLR) trigger generated from MME towards GMLC for emergency calls, based on the dedicated bearer states either creation or deletion.

Syntax

Syntax Description

[ no ] slr emergency dedicated-bearer-only

no

Disables the SLR trigger for dedicated bearer states.

slr

Specifies the SLR message from MME.

emergency

Specifies the trigger for sending the SLR message for emergency calls.

dedicated-bearer-only

Specifies the MME to trigger SLR towards GMLC upon dedicated bearer creation and deletion.

Usage Guidelines

Use this command to enable or disable the Subscriber Location Report (SLR) message trigger for emergency calls based on the dedicated bearer states either creation or deletion. In case of multiple dedicated bearers, SLR message with Call-Origination is sent upon the creation of first dedicated bearer and Call-Release is sent upon the deletion of last dedicated bearer irrespective of QCI. This command will override the current/default behavior of MME which initiates the SLR towards GMLC only upon Emergency Attach/PDN creation/PDN deletion and Detach.

By default, MME triggers the SLR message towards GMLC upon successful Emergency Attach/PDN creation/PDN deletion and Detach with appropriate event type (Call-Origination/Call-Release/Call-Handover).

default timeout { area-event-invoke-timer | lcsn | periodic-event-invoke-timer | ue-available-guard-timer }

default

Resets the specified timer to the default value.

area-event-invoke-timer area_event_timer

This timer, set in seconds, is used to guard the area event invoke procedure.

area_evt_timer is an integer from 10 through 20. Default is 15.

lcsn lcsn_seconds

Sets the NAS location service notification timer defining how long the SGSN will wait (in seconds) before aborting the Location Service Request, and release all resources allocated for the transaction.

lcsn_seconds is an integer from 10 through 20. Default is 15.

periodic-event-invoke-timer period_event_timer

Thi timer, set in seconds, is used to guard the period location invoke procedure.

period_evt_timer is an integer from 10 to 20. Default is 15.

ue-available-guard-timer ue_guard_timer

This timer, set in seconds, is used to guard the packet-switched deferred location request (UE available event) procedures.

ue_guard_timer is an integer from 10 to 600. Default is 600.

Usage Guidelines

Use this command to set the amount of time the SGSN waits to perform various location service procedures.
