Problems solved by technology

While this use of signal-based position information referenced to a global coordinate system may be useful in providing some services (e.g., outdoor vehicle navigation), for other types of services, such as indoor pedestrian navigation, such global coordinate system-referenced signal-based location information may be impractical

Embodiment Construction

[0028] In some cases, indoor navigation assistance data (INAD) may be provided from a computing device (eg, a server and / or other similar electronic device) to a mobile device over one or more wireless communication links. For example, the mobile device may store all or part of the received INAD in local memory. However, it should be appreciated that in larger indoor areas, where there may be multiple access points and a large number of feasible routes and / or points of interest, the available INAD may be quite lengthy and may not Bandwidth and / or data storage space (memory) on the mobile device poses a significant burden. Furthermore, it should be understood that in some cases, the mobile device may not actually need or use all or available INADs.

[0029] As illustrated by the examples herein, various methods, apparatus, and articles of manufacture can be implemented in one or more computing platforms for adaptively providing INAD updates for use by mobile devices. As descr...

Abstract

Various methods, apparatus, and articles of manufacture for adaptively providing and / or obtaining indoor navigation assistance data (INAD) updates for use by mobile devices may be implemented in one or more computing platforms. The INAD update includes a subset of INAD that can be used in indoor environments. Such a subset is determined based at least in part on bounded areas in the electronic map of the indoor environment. Such a bounded area has a shape and / or size based at least in part on at least one parameter indicative of a state of motion of the mobile device.

Description

[0001] related application [0002] This is a PCT application claiming U.S. Provisional Patent Application No. 61 / 641,416, filed May 2, 2012, entitled "ADAPTIVE UPDATING OF INDOOR NAVIGATION ASSISTANCE DATAFOR USE BY A MOBILE DEVICE" and filed in July 2012 Priority to U.S. Nonprovisional Patent Application No. 13 / 545,858, entitled "ADAPTIVE UPDATING OF INDOORNAVIGATION ASSISTANCE DATA FOR USE BY A MOBILE DEVICE," filed on the 10th, which is hereby incorporated by reference in its entirety. technical field [0003] The subject matter disclosed herein relates to electronic devices, and more particularly to methods, apparatus, and articles of manufacture in one or more computing platforms for adaptively updating indoor navigation assistance data (INAD) for use with mobile devices. Background technique [0004] Mobile devices such as mobile phones, notebooks, computers, etc. typically have the ability to use signals such as satellite positioning systems (e.g., GPS, etc.), Advanc...
