Location Service
Configuration Mode Commands
The Location Service
Configuration Mode is used to manage LoCation Services (LCS). Using
LCS, the system (MME or SGSN) can collect and use or share location
(geographical position) information for connected UEs in support
of a variety of location services.
Mode
Exec > Global Configuration
> Context Configuration > Location Service Configuration
configure > context context_name > location-service service_name
Entering the above
command sequence results in the following prompt:
[context_name]host_name(config-location-service)#
Important: The commands or keywords/variables
that are available are dependent on platform type, product version,
and installed license(s).
associate
Associates or disassociates supportive interfaces or services with
this location service instance.
Mode
Exec > Global Configuration > Context Configuration >
Location Service Configuration
configure > context
context_name
> location-service
service_name
Entering the above command sequence results in the following prompt:
[context_name]host_name(config-location-service)#
Syntax
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.
Example
The following command associates a pre-configured Diameter endpoint named test12 to this location service: associate diameter endpoint test12
destination-host
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.
Mode
Exec > Global
Configuration > Context Configuration > Location Service Configuration
configure > context
context_name
> location-service
service_name
Entering the above
command sequence results in the following prompt:
[context_name]host_name(config-location-service)#
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.
Example
The following
command specifies a destination host named
host123 for the
location service:
destination-host host123
end
Exits the current configuration mode and returns to the Exec mode.

Syntax Description
end
Usage Guidelines
Use this command to return to the Exec mode.
exit
Exits the current mode and returns to the parent configuration mode.

Syntax
Syntax Description
exit
Usage Guidelines
Use this command to return to the parent configuration mode.
slr
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.
Mode
Exec > Global
Configuration > Context Configuration > Location Service Configuration
configure > context
context_name
> location-service
service_name
Entering the above
command sequence results in the following prompt:
[context_name]host_name(config-location-service)#
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).
timeout
Configures the
timers used to control various location service procedures.
Mode
Exec > Global
Configuration > Context Configuration > Location Service Configuration
configure > context
context_name
> location-service
service_name
Entering the above
command sequence results in the following prompt:
[context_name]host_name(config-location-service)#
Syntax
Syntax Description
timeout { area-event-invoke-timer area_event_timer | lcsn lcsn_seconds | periodic-event-invoke-timer period_event_timer | ue-available-guard-timer ue_guard_timer }
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.
Example
The following
command is used to set the time the SGSN will wait, for example
12 seconds,
before aborting the Location Service Request:
timeout lcns 12
The following command is used to set the timeout for the UE
available guard timer to
460 seconds:
timeout ue-available-guard-timer 460
