SIGNALING SUPPORT ENABLING QOS DISCRIMINATION FOR POSITIONING, LOCATION AND LOCATION-BASED SERVICES IN LTE

摘要

According to one aspect of the present invention, the number of client and/or service types used in location-based services is extended. 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.
