4 Detailed service description
Terminal Location provides access to the location of a terminal through:
• Request for the location of a terminal.
• Request for the location of a group of terminals.
• Notification of a change in the location of a terminal.
• Notification of terminal location on a periodic basis.
• Location is expressed through a latitude, longitude, altitude and accuracy.
When a request for a group of terminals is made, the response may contain a full or partial set of results. This allows the
service to provide results based on a number of criteria including number of terminals for which the request is made and
amount of time required to retrieve the information. This allows the requester to initiate additional requests for those
terminals for which information was not provided.
5 Namespaces

6 Sequence diagrams
6.1 Terminal location query
Pattern: Request / Response.
For an application to determine the location of a terminal device, it provides a terminal device address and desired
accuracy, and receives the location for the device requested.
: Application : Terminal Location
Web Service
Request terminal location
Retrieve location

6.2 Terminal location group query
Pattern: Request / Response.
When an application requires the locations of a set of terminal devices, it may provide an array of terminal device
addresses, including network managed group addresses, and receive the location data for the set of devices requested.
: Application : Terminal Location
Web Service

6.3 Terminal location notification
Pattern: Application Correlated Multiple Notification.
An application can be notified of a terminal device entering or leaving a geographical area. When a matching event
occurs; a notification message will be sent to the application.
: Application : Terminal Location : Notification : Notification
Web Service Application Web Service
Create correlation id
Create notification with correlator
At some later time, an event occurs to
trigger the notification
Notification with correlator
At some later time, the notification may
be cancelled
Cancel notification with correlator

12 ETSI ES 202 504-9 V1.1.1 (2008-05)
6.4 Terminal location notification with check immediate
In some applications, the terminal location notification will be used to watch for a specific location change. An example
is a 'call when present' service, where the terminal location is checked and determined to be outside the target area, and
a notification is set up to notify the application when the terminal enters the target area. Between the time of the original
location determination and the time the notification is set up, the terminal could move into the target area, thus the
notification on entry into the target area would not be sent.
Using the check immediate flag, after the notification is established, the terminal location will be determined, and if the
terminal is in the target area, then a notification will be sent immediately. The following sequence diagram shows this
scenario.
: Application : Terminal Location : Terminal Location : Notification : Notification
Web Service Notification Application Web Service
Get location
Location
Create correlator
Start geographical notification with check immediate
Set up notification
Check terminal location
Location notification
Apply count to notification
Status end
Void

Figure 4
This sequence shows:
• The Enterprise Application checks the location of a terminal, and receives its location (in this scenario
determining that the terminal is outside the target area).
• The Enterprise Application generates a correlator, and starts a notification with criteria defined to notify the
Enterprise Web Service when the terminal enters the target area and the check immediate flag set to true.
• Sets up the notification to monitor terminal location.
• Check the current location of the terminal, and determine if the terminal lies inside the target area.
ETSI

---------------------- Page: 12 ----------------------
13 ETSI ES 202 504-9 V1.1.1 (2008-05)
• In this case, the terminal is in the target area, and a notification is delivered to the Enterprise Web Service.
• The count of notifications is incremented and compared to the notification count limit.
• In this case, a single notification was requested, and the end notification message is sent.
• The startGeographicalNotification operation completes.
This scenario includes the full set of interactions in one sequence, which also shows that the notifications can be
received concurrent with the creation of the notification.
6.5 Terminal location periodic notification
Pattern: Application Correlated Multiple Notification.
An application can be notified of a terminal device location on a periodic basis. At each interval, a notification message
will be sent to the application.
: Application : Terminal Location : Notification : Notification
Web Service Application Web Service
Create correlation id
Create notification with correlator
Set up timer
Repeat for intervals
Timer expiration Notification with correlator
At some later time, the notification may
be cancelled
Cancel notification with correlator

7 XML Schema data type definition
7.1 Latitude and Longitude values
Latitude and longitude values used in the present document follow the conventions of the ISO 6709 [3] specification, as
it applies to latitudes and longitudes specified using decimal degrees.
Latitude values are expressed as floating point numbers in the range -90,0000 to +90,0000, using decimal degrees (as
opposed to minutes and seconds). Positive values indicate locations north of and on the equator. Negative values
indicate locations south of the equator.
Longitude values are expressed as floating point numbers in the range -180,0000 to +180,0000, using decimal degrees
(as opposed to minutes and seconds). Positive values indicate locations east of and on the prime meridian (Greenwich).
th
Negative values indicate locations west of the prime meridian up to the 180 meridian.
7.2 Accuracy values
Two accuracy values are used in some of the operations. These values express the desire of the application for the
location information to be provided by the Web Service. The choice of values may influence the price that the Service
Provider charges.
• The 'requested accuracy' expresses the range in which the application wishes to receive location information.
This may influence the choice of location technology to use (for instance, cell sector location may be suitable
for requests specifying 1 000 meters, but GPS technology may be required for requests below 100 meters).
• The 'acceptable accuracy' expresses the range that the application considers useful, if the location cannot be
determined within this range, then the application would prefer not to receive the information. For instance, a
taxi tracking service to determine the closest taxi to a person may not be useful if the accuracy cannot be
provided within 1 000 meters to provide prompt service. This will also reduce customer satisfaction issues,
since results that are not useful can be handled appropriately for billing (e.g. Service Provider may choose not
to bill for these).
The 'maximum_age' expresses the maximum age of location information that the application considers useful. This can
be used by the service provider to supply cached location information rather than always to do a direct network location
request.
The 'response time' expresses the expected response time from an application point of view. If the network is unable to
respond within the desired time frame, the application would prefer not to have the information as it may no longer be
useful.
The 'tolerance' expresses the priority of response time versus accuracy. If the application is delay tolerant the network is
expected to return a location with the requested accuracy even if this means not complying with the requested response
time. The application can also indicate that it is more important that the location information is returned within the
requested time even if this implies that the requested accuracy can not be fulfilled. An indication of 'no delay' implies
that the application expects the service provider to return any current location estimate immediately.
In triggered notifications, a tracking accuracy is defined. This accuracy refers not to the accuracy for the area being
checked against, but rather for the accuracy of the technology used to track the terminal. For instance, a fine grained
tracking accuracy would be suitable for tracking the terminal entering a specific location, like a person arriving at a
destination building. A coarse grained tracking accuracy would be appropriate for determining when a person has
arrived at a city after a plane trip or a truck is in the vicinity of a warehouse.
7.3 EnteringLeavingCriteria enumeration
Indicator for whether the notification is related to entering an area or leaving an area.

4 Detailed service description
Terminal Location provides access to the location of a terminal through:
• Request for the location of a terminal.
• Request for the location of a group of terminals.
• Notification of a change in the location of a terminal.
• Notification of terminal location on a periodic basis.
• Location is expressed through a latitude, longitude, altitude and accuracy.
When a request for a group of terminals is made, the response may contain a full or partial set of results. This allows the
service to provide results based on a number of criteria including number of terminals for which the request is made and
amount of time required to retrieve the information. This allows the requester to initiate additional requests for those
terminals for which information was not provided.

6.3 Terminal location notification
Pattern: Application Correlated Multiple Notification.
An application can be notified of a terminal device entering or leaving a geographical area. When a matching event
occurs; a notification message will be sent to the application.
: Application : Terminal Location : Notification : Notification
Web Service Application Web Service
Create correlation id
Create notification with correlator
At some later time, an event occurs to
trigger the notification
Notification with correlator
At some later time, the notification may
be cancelled

12 Final draft ETSI ES 202 504-9 V1.1.1 (2008-02)
6.4 Terminal location notification with check immediate
In some applications, the terminal location notification will be used to watch for a specific location change. An example
is a 'call when present' service, where the terminal location is checked and determined to be outside the target area, and
a notification is set up to notify the application when the terminal enters the target area. Between the time of the original
location determination and the time the notification is set up, the terminal could move into the target area, thus the
notification on entry into the target area would not be sent.
Using the check immediate flag, after the notification is established, the terminal location will be determined, and if the
terminal is in the target area, then a notification will be sent immediately. The following sequence diagram shows this
scenario.
: Application : Terminal Location : Terminal Location : Notification : Notification
Web Service Notification Application Web Service
Get location
Location
Create correlator
Start geographical notification with check immediate
Set up notification
Check terminal location
Location notification
Apply count to notification
Status end
Void

Figure 4
This sequence shows:
• The Enterprise Application checks the location of a terminal, and receives its location (in this scenario
determining that the terminal is outside the target area).
• The Enterprise Application generates a correlator, and starts a notification with criteria defined to notify the
Enterprise Web Service when the terminal enters the target area and the check immediate flag set to true.
• Sets up the notification to monitor terminal location.
• Check the current location of the terminal, and determine if the terminal lies inside the target area.
ETSI

---------------------- Page: 12 ----------------------
13 Final draft ETSI ES 202 504-9 V1.1.1 (2008-02)
• In this case, the terminal is in the target area, and a notification is delivered to the Enterprise Web Service.
• The count of notifications is incremented and compared to the notification count limit.
• In this case, a single notification was requested, and the end notification message is sent.
• The startGeographicalNotification operation completes.
This scenario includes the full set of interactions in one sequence, which also shows that the notifications can be
received concurrent with the creation of the notification.
6.5 Terminal location periodic notification
Pattern: Application Correlated Multiple Notification.
An application can be notified of a terminal device location on a periodic basis. At each interval, a notification message
will be sent to the application.
: Application : Terminal Location : Notification : Notification
Web Service Application Web Service
Create correlation id
Create notification with correlator
Set up timer
Repeat for intervals
Timer expiration Notification with correlator
At some later time, the notification may
be cancelled
Cancel notification with correlator

7 XML Schema data type definition
7.1 Latitude and Longitude values
Latitude and longitude values used in the present document follow the conventions of the ISO 6709 [3] specification, as
it applies to latitudes and longitudes specified using decimal degrees.
Latitude values are expressed as floating point numbers in the range -90,0000 to +90,0000, using decimal degrees (as
opposed to minutes and seconds). Positive values indicate locations north of and on the equator. Negative values
indicate locations south of the equator.
Longitude values are expressed as floating point numbers in the range -180,0000 to +180,0000, using decimal degrees
(as opposed to minutes and seconds). Positive values indicate locations east of and on the prime meridian (Greenwich).
th
Negative values indicate locations west of the prime meridian up to the 180 meridian.
7.2 Accuracy values
Two accuracy values are used in some of the operations. These values express the desire of the application for the
location information to be provided by the Web Service. The choice of values may influence the price that the Service
Provider charges.
• The 'requested accuracy' expresses the range in which the application wishes to receive location information.
This may influence the choice of location technology to use (for instance, cell sector location may be suitable
for requests specifying 1 000 meters, but GPS technology may be required for requests below 100 meters).
• The 'acceptable accuracy' expresses the range that the application considers useful, if the location cannot be
determined within this range, then the application would prefer not to receive the information. For instance, a
taxi tracking service to determine the closest taxi to a person may not be useful if the accuracy cannot be
provided within 1 000 meters to provide prompt service. This will also reduce customer satisfaction issues,
since results that are not useful can be handled appropriately for billing (e.g. Service Provider may choose not
to bill for these).
The 'maximum_age' expresses the maximum age of location information that the application considers useful. This can
be used by the service provider to supply cached location information rather than always to do a direct network location
request.
The 'response time' expresses the expected response time from an application point of view. If the network is unable to
respond within the desired time frame, the application would prefer not to have the information as it may no longer be
useful.
The 'tolerance' expresses the priority of response time versus accuracy. If the application is delay tolerant the network is
expected to return a location with the requested accuracy even if this means not complying with the requested response
time. The application can also indicate that it is more important that the location information is returned within the
requested time even if this implies that the requested accuracy can not be fulfilled. An indication of 'no delay' implies
that the application expects the service provider to return any current location estimate immediately.
In triggered notifications, a tracking accuracy is defined. This accuracy refers not to the accuracy for the area being
checked against, but rather for the accuracy of the technology used to track the terminal. For instance, a fine grained
tracking accuracy would be suitable for tracking the terminal entering a specific location, like a person arriving at a
destination building. A coarse grained tracking accuracy would be appropriate for determining when a person has
arrived at a city after a plane trip or a truck is in the vicinity of a warehouse.
7.3 EnteringLeavingCriteria enumeration
Indicator for whether the notification is related to entering an area or leaving an area.

Pattern: Request / Response.
When an application requires the locations of a set of terminal devices, it may provide an array of terminal device
addresses, including network managed group addresses, and receive the location data for the set of devices requested.
: Application : Terminal Location
Web Service
Request terminal location for group
Process groups
Retrieve locations

6.3 Terminal location notification
Pattern: Application Correlated Multiple Notification.
An application can be notified of a terminal device entering or leaving a geographical area. When a matching event
occurs; a notification message will be sent to the application.
: Application : Terminal Location : Notification : Notification
Web Service Application Web Service
Create correlation id
Create notification with correlator
At some later time, an event occurs to
trigger the notification
Notification with correlator
At some later time, the notification may
be cancelled

6.4 Terminal location notification with check immediate
In some applications, the terminal location notification will be used to watch for a specific location change. An example
is a 'call when present' service, where the terminal location is checked and determined to be outside the target area, and
a notification is set up to notify the application when the terminal enters the target area. Between the time of the original
location determination and the time the notification is set up, the terminal could move into the target area, thus the
notification on entry into the target area would not be sent.
Using the check immediate flag, after the notification is established, the terminal location will be determined, and if the
terminal is in the target area, then a notification will be sent immediately. The following sequence diagram shows this
scenario.
: Application : Terminal Location : Terminal Location : Notification : Notification
Web Service Notification Application Web Service
Get location

Create correlator
Start geographical notification with check immediate
Set up notification
Check terminal location

Apply count to notification
Status end

This sequence shows:
• The Enterprise Application checks the location of a terminal, and receives its location (in this scenario
determining that the terminal is outside the target area).
• The Enterprise Application generates a correlator, and starts a notification with criteria defined to notify the
Enterprise Web Service when the terminal enters the target area and the check immediate flag set to true.
• Sets up the notification to monitor terminal location.
• Check the current location of the terminal, and determine if the terminal lies inside the target area.

• In this case, the terminal is in the target area, and a notification is delivered to the Enterprise Web Service.
• The count of notifications is incremented and compared to the notification count limit.
• In this case, a single notification was requested, and the end notification message is sent.
• The startGeographicalNotification operation completes.
This scenario includes the full set of interactions in one sequence, which also shows that the notifications can be
received concurrent with the creation of the notification.
6.5 Terminal location periodic notification
Pattern: Application Correlated Multiple Notification.
An application can be notified of a terminal device location on a periodic basis. At each interval, a notification message
will be sent to the application.
: Application : Terminal Location : Notification : Notification
Web Service Application Web Service
Create correlation id
Create notification with correlator
Set up timer
Repeat for intervals
Timer expiration Notification with correlator
At some later time, the notification may
be cancelled
Cancel notification with correlator

7 XML Schema data type definition
7.1 Latitude and Longitude values
Latitude and longitude values used in the present document follow the conventions of the ISO 6709 [3] specification, as
it applies to latitudes and longitudes specified using decimal degrees.
Latitude values are expressed as floating point numbers in the range -90,0000 to +90,0000, using decimal degrees (as
opposed to minutes and seconds). Positive values indicate locations north of and on the equator. Negative values
indicate locations south of the equator.
Longitude values are expressed as floating point numbers in the range -180,0000 to +180,0000, using decimal degrees
(as opposed to minutes and seconds). Positive values indicate locations east of and on the prime meridian (Greenwich).
th
Negative values indicate locations west of the prime meridian up to the 180 meridian.
7.2 Accuracy values
Two accuracy values are used in some of the operations. These values express the desire of the application for the
location information to be provided by the Web Service. The choice of values may influence the price that the Service
Provider charges.
• The 'requested accuracy' expresses the range in which the application wishes to receive location information.
This may influence the choice of location technology to use (for instance, cell sector location may be suitable
for requests specifying 1 000 meters, but GPS technology may be required for requests below 100 meters).
• The 'acceptable accuracy' expresses the range that the application considers useful, if the location cannot be
determined within this range, then the application would prefer not to receive the information. For instance, a
taxi tracking service to determine the closest taxi to a person may not be useful if the accuracy cannot be
provided within 1 000 meters to provide prompt service. This will also reduce customer satisfaction issues,
since results that are not useful can be handled appropriately for billing (e.g. Service Provider may choose not
to bill for these).
The 'maximum_age' expresses the maximum age of location information that the application considers useful. This can
be used by the service provider to supply cached location information rather than always to do a direct network location
request.
The 'response time' expresses the expected response time from an application point of view. If the network is unable to
respond within the desired time frame, the application would prefer not to have the information as it may no longer be
useful.
The 'tolerance' expresses the priority of response time versus accuracy. If the application is delay tolerant the network is
expected to return a location with the requested accuracy even if this means not complying with the requested response
time. The application can also indicate that it is more important that the location information is returned within the
requested time even if this implies that the requested accuracy can not be fulfilled. An indication of 'no delay' implies
that the application expects the service provider to return any current location estimate immediately.
In triggered notifications, a tracking accuracy is defined. This accuracy refers not to the accura
