The present invention relates generally to location-based services. More particularly, the present invention relates to anticipatorily providing information and/or services to a user based upon the user's location.
This section is intended to provide a background or context to the invention that is recited in the claims. The description herein may include concepts that could be pursued, but are not necessarily ones that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section.
Services based on the location of mobile devices are becoming increasingly widespread. In location-based services, content delivered and rendered at the device or terminal of a particular service requestor may change depending upon the location of the service requester. For example, in the case of advertisements, different advertisements may be sent to a terminal based upon the terminal's location.
Location-based services may also provide assistance data for assisted navigation systems, such as Global Navigation Satellite Systems (GNSS). Such assistance data has been specified and standardized for cellular systems, e.g., Assisted Global Positioning System (AGPS). A GNSS can comprise a network of satellites that broadcasts navigation signals including time and navigation data. GNSS receivers pick up these broadcasted navigation signals and calculate a precise global location based thereon. Examples of GNSS include, but are not limited to, global positioning systems (GPS), Galileo, GLONASS, satellite-based augmentation systems (SBAS), local area augmentation systems (LAAS) and quasi-zenith satellite systems (QZSS).
The delivery of such assistance data can be built on top of cellular system-specific control plane protocols including, e.g., the radio research location services protocol (RRLP) for GSM networks, the radio resource control (RRC) layer of layer 3 in wideband code division multiple access (WCDMA) networks, and IS-801 for CDMA networks.
One feature of location-based systems is the ability to anticipatorily send information of interest. For example, a person/terminal may be notified about a service and/or offer that is located within a certain number of meters of the terminal's location. The person then has the opportunity to “react” to the information. In a particular example, if a user is moving and comes within half a kilometer of a coffee shop, an advertisement for the coffee shop may be rendered on the user's terminal at the half-kilometer distance so that he or she has the opportunity to decide whether to stop at the coffee shop before passing it.
Various embodiments provide a system and method by which an estimate can be provided to a location-based service provider concerning the motion state of a user of a terminal. Such motion state information may be used to trigger a particular location-based service at a more optimal moment. This motion state information may also be used to help define the format of information sent to the user's terminal, as well as to define the content of the information that is to be sent to the user's terminal. This enables an improved level of control of the distribution of location-based services, as information can be sent at a more optimal time and more relevant information can be sent to the user.
These and other advantages and features of the invention, together with the organization and manner of operation thereof, will become apparent from the following detailed description when taken in conjunction with the accompanying drawings, wherein like elements have like numerals throughout the several drawings described below.
Various embodiments provide a system and method by which an estimate can be provided to a location-based service provider concerning that motion state of a user of a terminal. Such motion state information may be used to trigger a particular location-based service at an optimal moment. This motion state information may also be used to help define the format of information sent to the user's terminal, as well as to define the content of the information that is to be sent to the user's terminal. This enables an improved level of control of the distribution of location-based services, as information can be sent at a more optimal time and more relevant information can be sent to the user.
In a number of conventional systems for providing location-based services, the distance to a particular location is the only primary factor considered when deciding when a location-based service should be provided to a user terminal. For example, in the example of a coffee shop discussed previously, an advertisement for the coffee shop would be rendered on the user's terminal when the user terminal is within a half-kilometer distance of the coffee shop, regardless of the rate at which the user is travelling. Although this arrangement may be useful when the user is travelling at a low rate of speed, e.g., when the user is walking or jogging, it becomes significantly less useful when the user is travelling at highway speeds in an automobile, since the user would have only a few seconds to view the advertisement to decide whether or not to stop at the coffee shop and then change his or her driving course so as to stop at the coffee shop. However, by the time the user decides that he or she wants to stop, the vehicle may have already passed the coffee shop entirely.
In addition to the above, other content-related issues may not be addressed in a situation where the only information used in providing location-based services is the user's location at a given moment. For example, if the user terminal is being used by a pedestrian, the user may be able to simply enter a shop directly from the street in response to the viewing of a location-based advertisement. However, if the user is driving an automobile, the user may also have to find a parking space before entering the shop.
Various embodiments provide a system and method by which information about the motion state of the user terminal is used to provide location-based services. In various embodiments an estimate of the motion state of the user is provided to the location-based service provider, and this information is used to customize the content provided to the user and/or the timing at which the content is provided.
By providing motion state information, more relevant and better-timed location-based services can be provided to the user. Returning to the coffee shop situation, for example, the timing of the advertisement for the coffee shop can be adjusted based upon the motion state of the user. If it has been determined that the optimal time to provide the advertisement to the user is three minutes before the user would reach the coffee shop, then the motion state information could be used by the location-based service provider to deliver the advertisement when the user is a half-kilometer way, when the user is walking, or five kilometres away when the user is travelling in a car. Additionally, if the motion state information indicates that the user is travelling in a car, then the location-based service provider may decide to provide parking information to the user, in addition to the advertisement for the coffee shop. If, on the other hand, the motion state information indicates that the user is walking or jogging, then the parking information would not be sent since it is not needed by the user.
In various embodiments, information concerning the motion state of the terminal can be transmitted to the location-based service provider using, for example, a simple bit representation. A chart showing an example of how different motion states may be identified with bit representations is shown below.
Information used to determine the motion state may be based upon, for example, a GNSS receiver velocity estimate and/or a sensor/sensor suite located within the user terminal. In the case where one or more sensors are used, the sensors may comprise, for example, inertial sensors. Although a GNSS receiver velocity estimate may pose issues in situations such as inner city driving, where a vehicle stuck in a traffic jam could be moving at a velocity similar to the rate at which a pedestrian or cyclist moves, for example, it does provide the benefit of including heading information which may also be of interest to an location-based service provider. If, for example, the user terminal is capable of indicating that the user is rapidly moving away from a coffee shop, then the location-based service provider would not provide an advertisement for that establishment. When a GNSS receiver velocity estimate is used, the motion state may be further defined relative to the estimated velocity of the terminal. For example, there could be multiple “Car” bit representations-one for highway speeds, one for city driving speeds, etc. In further embodiments, more accurate information concerning the velocity of the user terminal could be transmitted, making it possible for the location-based service provider to even further fine tune the content and/or timeliness of the location-based services.
In the case of an inertial sensor/inertial sensor suite, such components rely upon the idea that each transportation mode and motion state has its own vibration characteristics that can be used to differentiate between them. For example, the vibration characteristics for walking are different than for cycling, which are different for travelling in a vehicle, etc.
Regardless of whether sensors, a GNSS receiver velocity estimate, or other devices are used to determine the motion state, the categories of motion states can vary greatly. For example, individual motion states representing travel by automobile, train, boat, airplane, bicycle, etc. and other vehicles may be represented by different bit representations.
