Location Service Requests Throttling

摘要

A technique to allow a server such as a location server to throttle concurrent or closely timed location requests for the position of a given wireless device such that within a certain time period preferably only one location request will be initiated to the positioning engine and the remaining closely-timed location requests will be buffered or cached. When a position for the given wireless device is returned per the outstanding location request, then the retrieved position will be used to respond to each of the buffered location requests. Thus, a plurality of location requests are satisfied with a single request to the positioning engine. By optimizing the use of cached position requests, throttling of location requests per the invention reduces network traffic significantly, increases the efficiency of a positioning server (therefore reducing business cost), and provides for an improved grade or quality of location based services in general.

主权项

1. A technique for throttling location requests relating to a wireless device, comprising:
logging a plurality of location requests within a short period of time relating to a position of said wireless device; allowing only one of said logged plurality of location requests through to a positioning engine relating to said wireless device; and using a location returned to said only one of said logged plurality of location requests as a location returned in remaining ones of said plurality of location requests.
