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 } | 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.
Examples
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 for be a 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.
end
Exits the current configuration mode and returns to the Exec mode.

Usage Guidelines
Use this command to return to the parent configuration mode.
timeout
Configures the timers used to control various location service
procedures.
Mode

> location-service
service_name
Entering the above command sequence results in the following prompt:
[context_name]host_name(config-location-service)#
Syntax
Syntax Description
[ default ] timeout { area-event-invoke-timer aietimer_seconds | lcsn lcns_seconds | periodic-event-invoke-timer peitimer_seconds | ue-available-guard-timer ueagtimer_seconds
default
Resets the specified timer to the default value.
area-event-invoke-timer
aietimer_seconds
This timer, set in seconds, is used to guard the area event invoke
procedure.
aietimer_seconds is an integer from 10
through 20. Default is 15.
lcsn
lcns_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.
lcns_seconds is an integer from 10 through
20. Default is 15.
periodic-event-invoke-timer
peitimer_seconds
Thi timer, set in seconds, is used to guard the period location invoke
procedure.
peitimer_seconds is an integer from 10 to
20. Default is 15.
ue-available-guard-timer
ueagtimer_seconds
This timer, set in seconds, is used to guard the packet-switched
deferred location request (UE available event) procedures.
ueagtimer_seconds 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.
Examples
The following command can be 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 can be used to set the
timeout for the UE available guard timer to
460 seconds:
timeout ue-available-guard-timer 460
