Abstract

A method for improving discovery of preferred mobile computing locations includes monitoring sensor data corresponding to a mobile computing device (MCD) and monitoring non-GPS network data implemented by the mobile computing device. Additionally, the method determines whether sensor data and non-GPS network data indicate that the mobile computing device is stationary within a cell site as well as scanning any network that the mobile computing device is electronically linked to. In short, the method discovers an improved preferred mobile computing location based on the sensor data and non-GPS network data that provide reliable information that the mobile computing device is stationary within the cell site. The sensor data and non-GPS network data are converged when several corresponding scans produce overlapping results.

Description

RELATED CASES

The present application is related to U.S. application Ser. No. 13/103,377, filed May 9, 2011, and whose contents are incorporated by reference in their entirety.

FIELD OF INVENTION

This invention is directed to mobile computing devices and their users. More specifically, the invention is directed to enabling the mobile computing device to more closely align with a particular user's preferences.

BACKGROUND

There is great interest in adjusting behavior of a mobile computing device (MCD) to suit or benefit the user of the MCD according to that user's personal taste. For example, the behavior of a MCD can be modified by adjusting associated ringers or ringtones, turning on its Wi-Fi communication in one location versus another location (e.g., home versus work locations), as well as affecting accompanying Bluetooth and GPS operation. All of these adjustments are usually done manually by the user and must be remembered to do so.
Some solutions involve collecting locations based on GPS locations. However, GPS locations may not always be available, especially inside a building. Additionally, using GPS places a significant power drain on the battery of a MCD.

DETAILED DESCRIPTION

The following detailed description is merely illustrative in nature and is not intended to limit the embodiments of the subject matter or the application and uses of such embodiments. As used herein, the word “exemplary” means “serving as an example, instance, or illustration.” Any implementation described herein as exemplary is not necessarily to be construed as preferred or advantageous over other implementations. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.
Before describing in detail embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of method steps and device components related to associating objects in an electronic device. Accordingly, the device components and method steps have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
In this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the method, or device that comprises the element. Also, throughout this specification the term “key” has the broad meaning of any key, button or actuator having a dedicated, variable or programmable function that is actuated by a user.
Techniques and technologies may be described herein in terms of functional and/or logical block components, and with reference to symbolic representations of operations, processing tasks, and functions that may be performed by various computing components or devices. Such operations, tasks, and functions are sometimes referred to as being computer-executed, computerized, software-implemented, or computer-implemented. In practice, one or more processor devices can carry out the described operations, tasks, and functions, and the various block components shown in the figures may be realized by any number of hardware, software, and/or firmware components configured to perform the specified functions. For example, an embodiment of a system or a component may employ various integrated circuit components, e.g., memory elements, digital signal processing elements, logic elements, look-up tables, or the like, which may carry out a variety of functions under the control of one or more microprocessors or other control devices. For the sake of brevity, conventional techniques related to signal processing, data transmission, signaling, network control, and other functional aspects of the systems (and the individual operating components of the systems) may not be described in detail herein. Furthermore, the connecting lines shown in the various figures contained herein are intended to represent exemplary functional relationships and/or physical couplings between the various elements. It should be noted that many alternative or additional functional relationships or physical connections may be present in an embodiment of the subject matter.
A method for discovering preferred mobile computing locations includes monitoring amount of time a mobile computing device is located within a cell tower region; and monitoring amount of time a mobile computing device is located within a Wi-Fi region. Afterwards, the method collects mobile computing device location data corresponding to the monitoring of cell tower region and Wi-Fi region; and analyzes the mobile computing device location data to determine amount of time and frequency of visits that the mobile computing device is in the cell tower and Wi-Fi regions. The above steps can be controlled via a processor within the mobile computing device such that a preferred mobile computing location is discovered for a user of the mobile computing device. Cell ID and Wi-Fi network ID are employed herein and are described by way of example, however, it is also contemplated that physical sensors associated with the MCD may also be monitored to determine meaningful locations of the user. For example, infrared sensors, integrated Bluetooth systems, retina-scanning devices, and fingerprint devices. Just as important can be certain characteristics about the mobile computing device itself. For example, usage characteristics (e.g., phone calls, emails, text, game playing, remaining battery level, etc.) and mobile computing application selections at certain locations versus different usage characteristics and application selections at other locations. Consequently, meaningful or preferred locations can be determined without using battery draining geographical location technology, such as global positioning system (GPS), or Global Navigation Satellite System (GLONASS), or Beidou Satellite Navigation System.
An exemplary MCD can operate under a set of programmable instructions. A set of instructions, when executed, may cause the MCD to perform any one or more of the methodologies described herein. In some embodiments, the MCD operates as a standalone device. In some embodiments, the MCD may be connected (e.g., using a network) to other MCDs. In a networked deployment, the MCD may operate in the capacity of a server or a client user MCD in a server-client user network environment, or as a peer machine in server-client user network environment, or as a peer machine in a peer-to-peer (or distributed) network environment.
The MCD may comprise a server computer, a client user computer, a personal computer (PC), a tablet PC, a personal digital assistant, a portable phone on a wireless or cellular network, a laptop computer, a smartphone either alone or combined with a display device, a control system, a network router, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine, not to mention a mobile server. It will be understood by those ordinarily skilled in the art of mobile computing and communication devices and associated networks, either wired or wireless that the mobile computing device described herein includes broadly any electronic device that provides voice, video, and data communication. Further, while a single MCD may be illustrated, the term “mobile computing device” shall also be taken to include any collection of mobile computing devices that individually or jointly executed a set (or multiple sets) of instructions to perform any one or more methodologies discussed herein.
An exemplary method for improving discovery of preferred mobile computing locations can include monitoring sensor data corresponding to a mobile computing device (MCD) and monitoring non-GPS network data implemented by the mobile computing device. Additionally, the exemplary method determines whether sensor data and non-GPS network data indicate that the mobile computing device is stationary within a cell site and scans any network that the mobile computing device is electronically linked to. In short, the method discovers an improved preferred mobile computing location based on the sensor data and non-GPS network data that provide reliable information that the mobile computing device is stationary within the cell site. The sensor data and non-GPS network data are converged when a plurality of corresponding scans produce overlapping results.
FIG. 1 illustrates a plurality of meaningful locations 100 of an exemplary user of a MCD. The plurality of meaningful locations 100 of a user of a MCD can include a home location 100, a work location 120, and a school location 125. Other possible locations are shown as well, for example library, parent's home, bookstore, church, soccer field, and a supplier's location. These locations are exemplary in nature and are not fully exhaustive. However, these locations make up a user's week in that they account for a percentage of the user's available time during week 130. A correlation of the time and frequency of where the user spends their time with the MCD in their possession can enable a determination of ‘meaningful locations’ for that user. These meaningful locations are also termed “preferred locations”.
FIG. 2 illustrates data about multiple locations that can be analyzed to determine the MCD user's preference regarding the location. The data is shown to be categorized into activities, type of communication network, type of connected peripherals to the MCD, and who the MCD may be communicatively connected to. Specifically, the activities category can include time, transitions from one activity to another (e.g., switching from texting to gaming), application usage (e.g., barcode scanning, music playing, movie database lookup, gaming, sports video playing, etc.), call or short messaging service (e.g., dialer, text messaging, social networking, etc.).
The communication networks category can include type of communication network, cellular identification, signal quality, and received signal strength indicator, for example. The peripheral category can include wireless local area networks and wireless metro area networks based on IEEE 802.11 standards, including Wi-Fi, for example; Bluetooth, digital living network alliance (DLNA), docks, and chargers. The database may also categorize the name of businesses, who the MCD communicatively connected to, primary and secondary residences, workplaces, and commerce establishments that the MCD user often interacts with.
The database in FIG. 2 is an example and therefore can include either more or less data in different hierarchical or nonhierarchical structures. The database enables optimization of battery life for the MCD and optimized network usage. This is accomplished by relying on the captured demographic data within the database to predict movement of the MCD between preferred or meaningful locations. Additionally, the database may be a basis for predictions associated with Wi-Fi usage or battery charging, for example. Other innovative MCD features can be derived that may affect automation, discovery, and social aspects of the MCD.
FIG. 3 illustrates a situation when the MCD user is between two overlapping cellular areas (i.e., “cells”). The MCD may periodically or intermittently switch connectivity from one cellular tower to the other cellular tower even though the MCD is itself relatively stationary. This phenomenon is sometimes referred to as “cell bouncing”, and has been shown to cause significant current drain upon the battery of the MCD, because several locations are attempting to be captured at once.
FIG. 4 illustrates a flowchart 400 that alleviates the “cell bouncing” phenomenon. Upon a cell change 410, an inquiry 420 determines whether the current cell connected to the MCD is in a bouncing cache. If the current cell connected to the MCD is in a bouncing cache, then a second inquiry 430 determines whether a location monitor timer is active. If the location monitor timer is not active, then in operation 433 a decay timer is stopped for the current cell and a decay timer is started for the previous cell. Otherwise, where a location monitor timer remains active all bouncing cache operations cease.
For inquiry 420, if the current cell connected to the MCD is not in a bouncing cache, a third inquiry 440 determines whether the location monitor timer is active. An affirmative answer to inquiry 440 leads to operation 443 that adds the current cell to a bouncing cache and restarts the location monitor timer. A bouncing cache herein includes the cache of cells that the user is frequently changing to due to radio frequency nature of mobile technology when the user is in areas shown in FIG. 3. These cell changes occur periodically even though the MCD is not moving and the “Bouncing Cache” includes the list of cells the MCD switches to without actually moving. A negative answer to inquiry 440 leads to operation 447 that empties the bouncing cache before adding the current cell to the now emptied bouncing cache. In short, when a location monitor timer expires, then a location is captured and decay timers are started for all cells except the current cell in the bouncing cache.
FIG. 5 illustrates the situation when a MCD user is in a cellular area (herein referred to as “cell”) and WiFi is used as a Network Location provider. If WiFi is turned off by the user, the location accuracy may not be perfect. Also, the accuracy provided by GPS may be greater, but GPS data is avoided in the present algorithm, because of its negative impact upon current usage. The novel solution described herein leverages when the user has connected the device to a charger. Thereafter, when the MCD is in charging mode, instructions are given to:

- Turn on WiFi, if it is not turned ON
- Turn on GPS, if it is not turned ON
- Capture the location with the best possible accuracy

FIG. 6 illustrates the situation when the same location gets different sensorial data at different times. For example, Location 1 sees Cell 1, Cell 2, via WiFi 1, WiFi 2 on Day 1. The same location sees Cell 1 & WiFi 1 only on day 2. Given the overlap of Cell 1 and WiFi 1 on both days, the locations are thereafter converged and treated as the same location as opposed to different locations. The WiFi points are used for the convergence.
FIG. 7 illustrates a timing diagram 700, wherein at T₀the MCD user arrives at a location. From T₁-T₀a location monitor timer filters out any transients. Whereas, between T₂-T₁, the amount of time a user spends at a particular location is derived.

Moreover, one or more of the tasks shown in a figure could be omitted from an embodiment of the respective process as long as the intended overall functionality remains intact. While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or embodiments described herein are not intended to limit the scope, applicability, or configuration of the claimed subject matter in any way.
