Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for a relatively faster time-to-first-fix, such as for use in or with a mobile communication device. Briefly, in accordance with at least one implementation, a method may include transmitting a first message to a mobile device, the first message comprising abbreviated positioning assistance data; receiving a second message from the mobile device, the second message comprising an indication of a coarse location of the mobile device; and transmitting a third message to the mobile device, the third message comprising a detailed tiled radio heat map obtained based, at least in part, on the received indication of the coarse location of the mobile device.

The subject matter disclosed herein relates to systems, methods, etc. for creating a routing graph based at least partly on building information. For certain example implementations, a method includes obtaining building information descriptive of at least a portion of a building structure. A grid of points may be superimposed onto the building information. At least one routing graph may be created based at least in part on the superimposed grid of points and the building information. Other example implementations are also described.

A system for the collection, aggregation and analysis of location based crowdsourcing data includes a server that server that controls the distribution of crowdsourcing requests and workloads to a plurality of external mobile platforms. The server receives crowdsourcing queries from multiple parties and provides measurement requests to the mobile platforms, e.g., based on the location of the mobile platforms. Upon receipt of the measured contextual data from the mobile platforms, the server may distribute information, such as the raw measured contextual data or an analysis of the measured contextual data, to the appropriate requesting parties in a secure manner. The mobile platform may receive a plurality of measurement requests from a remote server, wherein the plurality of measurement requests are based on crowdsourcing queries from a plurality of parties. The mobile platform may measure and provide to the remote server contextual data in response to the plurality of measurement requests.

The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for map handling for location based services in conjunction with localized environments. For certain example implementations, a method may comprise storing map information corresponding to a particular localized environment that is associated with a particular location context identifier, with the particular localized environment comprising an indoor environment corresponding to at least a portion of a building structure; receiving update information applicable to the map information corresponding to the particular localized environment, with the update information being associated with the particular location context identifier; updating the map information corresponding to the particular localized environment based at least partly on the update information so as to produce updated map information; and providing the updated map information to one or more mobile devices that are located at the particular localized environment. Other example implementations are described herein.

The subject matter disclosed herein relates to a location aware recommendation engine. In response to a recommendation request, relevant recommendations may be ranked based on the current location of a user, location associated with an entity, and/or accessibility criteria.
摘要:
Methods, apparatuses and/or articles of manufacture are provided that selectively distribute location based service content for use by mobile devices with regard to certain indoor environment(s). In one example implementation, one or more computing devices generate data files that collectively represent an initial content for use by a mobile device with regard to an indoor environment, wherein at least one of the data files is generated based, at least in part, on one or more distribution schemes relating to the indoor environment. The one or more computing devices selectively initiates transmission of an indication to one or more mobile devices identifying that a shared data file corresponding to a seeded data file may be obtained from a first mobile device. The first mobile device and/or one or more of the other mobile devices may be identified based, at least in part, on the one or more distribution schemes.
摘要:
A database of the location based relationships of points of interest within an environment is automatically generated using a digital representation of the environment that includes the points of interest at different locations within the environment. The locations of the points of interest in the environment are identified and the location based relationships between the points of interest are determined. The points of interest are labeled with the determined relationships and the points of interest and labeled relationships are stored. For example, a graph structure may be produced where each node is a point of interest and the edges between nodes is labeled with the determined relationships.
摘要:
Various methods, apparatuses and articles of manufacture may be implemented for use in one or more computing platforms to adaptively provide and/or obtain indoor navigation assistance data (INAD) update(s) for use by a mobile device. An INAD update may, for example, comprise a subset of INAD available for an indoor environment. Such a subset may be determined based, at least in part, on a bounded region in an electronic map of the indoor environment. Such a bounded region may, for example, have a shape and/or a size based, at least in part, on at least one parameter indicative of a motion state of the mobile device.

The subject matter disclosed herein relates to a system and method for automatically identifying features in an electronic map. In some embodiments, the method may comprise extracting features, which may include entryways and structural elements, from an electronic map. Based on the extracted features, one or more hallways may be identified in the electronic maps by using one or more line segments, which may extend between at least one entryway and one or more structural elements, and/or at least one entryway and one or more other entryways. The electronic map may be updated with one or more annotations identifying the one or more hallways.
