Signaling Support Enabling QoS Discrimination for Positioning, Location and Location-Based Services in LTE
First Claim
1. A method of providing positioning services in a wireless communication network that includes a positioning node that is configured to provide positioning information for a user equipment (UE) according to a selected positioning sequence, wherein different positioning sequences available at the positioning node offer different positioning response times or Quality-of-Service, wherein said method comprises:
- maintaining at a node in the wireless communication network an extended set of client types or service types corresponding to a plurality of different types of commercial location-based services, wherein the different types of commercial location-based services are distinguished in terms of their location QoS criteria;
receiving a positioning request at said node for locating a user equipment (UE);
mapping the positioning request to one of the extended client or service types corresponding to the particular type of commercial location-based service associated with the positioning request; and
signaling at least one of the following in a positioning request to the positioning node;
the extended client or service type;
location QoS criteria that is mapped by the node to the extended client or service type;
or a specific positioning sequence that is mapped by the node to the extended client or service type.

Abstract
One aspect of the present invention extends the number of client and/or service types used in location-based services. The extension provides richer definitions for use in selecting the optimal or otherwise best suited positioning sequences to be used in fulfilling given positioning requests. For example, some types of commercial-related positioning requests are better satisfied with quicker-but-lower-accuracy position determinations, while other types benefit from more-accurate-but-slower position determinations. These and other benefits are provided by extending the type definitions used to identify commercial positioning requests. For example, a UE may be configured to send positioning requests that indicate the extended client or service types. As another example, the network node(s) involved in generating or processing such requests are configured to understand the extended type definitions and/or to map the extended definitions to QoS requirements, or to particular positioning sequences, for requesting that a positioning node carry out that particular positioning sequence.
