7.1 Procedures for an LCS Client

These procedures are concerned with the LCS client’s provisioning and administration to the LCS feature.

7.1.1 Provisioning

Provisioning is an action to make the LCS feature available to a subscriber.

Provisioning may be:

– General: where the service may be made available to all subscribers without prior arrangements being made with the service provider (i.e. emergency calls).

‑ Pre‑arranged: where the service is made available to an individual LCS Client only after the necessary arrangements have been made with the service provider.

7.1.2 Withdrawal

Withdrawal is an action taken by the service provider to remove an available LCS feature from a LCS Client’s subscription profile.

Withdrawal may be:

‑ General: where the LCS feature is removed from all LCS Clients.

‑ Specific: where the LCS feature is removed on an individual basis per LCS Client.

7.1.3 Invocation

Invocation is an action to invoke the LCS feature, taken by the LCS Client (e.g. issuing a location request) or automatically by the LCS server as a result of a particular condition (e.g. periodic location request, mobile originating emergency call, etc.).

7.2 Procedures for a Target UE

These procedures are concerned with a Target UE’s privacy exception list. For emergency services, provisioning and withdrawal for Target UEs may not apply.

7.2.1 Provisioning

Provisioning is an an action to make the privacy exception list with its privacy classes available to a Target UE. The provision may be:

‑ General: where the list is made available to all Target UE’s without prior arrangements being made with the service provider. The list shall contain the default privacy class.

‑ Pre‑arranged: where any extra privacy permission class (–granting permission to locate an UE Client) shall be capable of being independently provisioned for a target UE as agreed with the service provider for a certain contractual period.

7.2.2 Withdrawal

Withdrawal is an action taken by the service provider to remove an available privacy class from a target UE’s PEL. Withdrawal may be:

‑ General: where a privacy class is removed from all target UEs provided with this privacy class.

‑ Specific: where each of the privacy classes in the privacy exception list shall be independently withdrawn at the subscriber’s request or for administrative reasons.

7.2.3 User Control

The user shall be able to change the following settings in the privacy exception list:

– the LCS Client and/or group of LCS Clients list

– the codeword

– the requestor

– the service types

– the target subscriber notification setting (with/without notification)

– the default treatment, which is applicable in the absence of a response from the Target UE for each LCS Client identifiers.

7.3 Barring Capability of the Location Service

It shall be possible for operators to bar the Location Service of a specific user at any time. i.e. any location requests towards the user’s Target UE and her own location requests towards her own Target UE are barred.

If the LCS request fails due to barring, then an error cause is returned to the LCS Requestor.

For Emergency Services and other services where required by local regulatory requirements, and for PLMN operator Services, the location request shall be processed with the highest priority level regardless of the barring status of LCS.
