20110159893 | Signaling Support Enabling QoS Discrimination for Positioning, Location and Location-Based Services in LTE - 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. | 06-30-2011 |
20110244879 | Method and Apparatus for use of Performance History Data in Positioning Method Selection - A method of selecting the positioning method(s) used to respond to given positioning requests uses historical performance data reflecting the actual performance yielded by one or more of the positioning methods that are generally available for selection. As a non-limiting example, a positioning node maintains or otherwise has access to historical data reflecting the QoS obtained for at least some of the positioning methods supported by the node. Correspondingly, the node compares the QoS requirements associated with an incoming positioning request to the historical performance data, to identify the positioning method(s) that appear to best satisfy the requirements. The positioning node therefore selects the “best” method(s) for responding to a positioning request, not based on “generic” performance characteristics of those methods, but rather based on observed real-world performance of those methods, as applicable to the particular operating environment (radio environment) in which the positioning methods are carried out. | 10-06-2011 |

20110294518 | Enhancement of Positioning Quality of Service - Teachings herein improve selection of the positioning method(s) used to obtain positioning information responsive to a positioning request, by approaching positioning QoS holistically.

Processing in one or more embodiments thus includes determining a joint QoS metric for each of a plurality of candidate positioning methods or sequences, and selecting a positioning method or sequence based on those joint QoS metrics. By selecting a positioning method or sequence in this way, holistically based on joint QoS metrics rather than a piecemeal approach based on a one-by-one check of individual QoS parameters, selection proceeds flexibly according to actual QoS requirements of position-based services and/or systematically according to the joint effect of multiple positioning methods. | 12-01-2011 |
