The invention relates to the field of geofences, and in particular to determining geofences for different positioning techniques.
The number of devices with location capabilities is expected to grow exponentially in the next decade or so. This growth is the result of the Internet-of-Things-era (IoT), in which more and more devices get connected to the Internet. Soon homes, factories, cities and transportation means will be equipped with low-cost sensors that produce real-time information on various characteristics and environment variables. Moreover, the cheaper electronics enables factories and industries to equip assets and supply chains with trackers that provide real-time information on the flow of goods.
The basic ingredient of the IoT story is that the sensors and trackers are location-aware. The location-awareness can be achieved through two means: either the device has its own positioning capabilities (like GNSS or cell/wifi/Bluetooth offline positioning) or the device makes measurements of the radio environment (cell/wifi/Bluetooth) and sends them to the cloud for position determination.
When it comes to small devices that must function autonomously for extended periods of time, power consumption is of special concern. The devices are powered by batteries and, thus, any means to reduce current drain are welcome. As far as location technologies are concerned, there are few ways to reduce power consumption. The greatest power saving results from using the correct technology at the correct time. To exemplify, when low location accuracy is adequate, it is advantageous to use cellular positioning, because it is cheap in terms of energy.
Location is important not only for simple tracking use cases, but also for event notifications. Specifically, when events are tied to geographical constraints, one talks about geofences. A geofence may, for example, be a circular area. When the device enters (or leaves) the defined area, an observer gets notified about the event. While geofences are powerful tools, they may also consume a lot of power. Thus, also in such use cases the correct choice of technology is of essence.

An operation of at least one apparatus will now be described with reference to the flow chart of
The at least one apparatus determines a representation of a geofence at least partially (which may include completely) based on a plurality of parameters, wherein at least one parameter of the plurality of parameters is indicative of an area-of interest geofence and at least one parameter of the plurality of parameters is associated with the respective positioning technique of the one or more positioning techniques (action 210). For instance, the at least one parameter of the plurality of parameters associated with the respective positioning technique may be indicative of the respective positioning technique and/or may represent one or more parameters being indicative of a positioning technique specific value, e.g. a size and/or shape of a radio coverage of a transmitter related to the respective positioning technique. For instance, if a plurality of representations of geofences are determined in action 210 for a respective positioning technique, two or more representations of the geofences of the plurality of representations of geofences may differ from each other, e.g. in shape and/or size.
For instance, the one or more positioning technique may be positioning techniques based on wireless communication, i.e., wireless positioning techniques.
A geofence may be considered to be a virtual perimeter for a real-world geographic area. For instance, a geofence may be set around an area-of-interest. As an example, a geofence may be defined by a point and a geometric shape around the point, e.g. a circle or an ellipse around the point. Or, as another example, a geofence may be defined by a polygon, wherein a polygon may be defined by a predefined set of boundaries. Thus, as example, the area of a geofence and/or the shape of a geofence may be defined by one of
A geofence may be considered to define an area around an area-of-interest. For instance, a geofence could be a check point or a check area on the delivery route of a vehicle, e.g. a truck, and somebody could be interested to know and get a notification when the delivery vehicle visits the check point (or check are), which could for example be one of the delivery locations (areas). Of course, a geofence could be used for any other well-suited area-of-interest, e.g. a school attendance zone or any other zone, wherein a notification may be issued if it is detected that a movable entity, e.g. a vehicle or any mobile device, is within the geofence, i.e., within the boundaries of the geofence. Or, for instance, the area-of-interest could be a factory and the purposed of the geofence may be to notify, when a spare part delivery arrives at the factory.

As an example, the area-of-interest 315, 325, 335 may be defined in response to a user interaction with apparatus 100, e.g. via an interface of apparatus 100. The representation of a geofence 310, 320, 330, determined in action 210 for a respective positioning technique may be determined in such a way that the geofence 310, 320, 330, 320, 330 at least partially, in particular completely, surrounds the area-of-interest 315, 325, 335.
For instance, said representation of a geofence may indicative of at least one of (i) a size of the geofence, and (ii) a shape of the geofence, wherein the geofence may be a geofence being around the area-of-interest. Furthermore, and/or, said representation of a geofence may be indicative of a geofence which is around the area-of-interest and thus may be considered to a full representation of the geofence.
As one example, such a size of a geofence may be indicative of the whole size of the geofence 310, 320, 330. Then, for instance, the size of the geofence may be a representative of or correlated to the whole area of the geofence. For instance, if the geofence is defined by a circle, then the radius, or the diameter or the circumference may be a representative of a size of the geofence, or as another example, if the geofence is defined by an ellipse or a polygon, the size being the whole size may be defined by the circumference of the ellipse 320 or the polygon 330 or another suitable representative being correlated with the area defined by the ellipse or the polygon.
As another example, such a size of a geofence may be indicative of an extension (or length) of the geofence in at least one direction (e.g. in exactly one direction). It may be assumed that the extension (or length) of the geofence goes through a predefined point within the area defined by the geofence, wherein this predefined point may represent the centre of the area defined by the geofence.
According to action 210 said at least one parameter of the plurality of parameters is indicative of a type of a respective positioning technique of the one or more positioning techniques. For instance, the respective positioning technique may be a positioning technique applied by or applied for a mobile device.
For instance, a mobile device may be part of may be moved by a movable entity, wherein the movable entity may be a vehicle, e.g. a car or a truck or a motorbike or any other suitable vehicle, or a bike or a person that carries the mobile device and may walk around. The mobile device may be configured to determine its position (e.g. its location) based on a positioning technique. Thus, as an example, the mobile device may comprise means for determining the position of the mobile device, e.g. based on wireless signals received according to a positioning technique. It has to be understood that not all of the one or more positioning techniques must be necessarily be supported by the mobile device. E.g. the mobile device may be configured to support at least one positioning technique of the one or more positioning techniques.
As an example, action 210, i.e., determining of a representation of a geofence at least partially based on a plurality of parameters, wherein at least one parameter of the plurality of parameters is indicative of an area-of interest geofence and at least one parameter of the plurality of parameters is indicative of a type of a respective positioning technique of the one or more positioning techniques, may allow to determine the representation of a geofence to match or to be optimized with respect to type of the respective positioning technique indicated by the least one parameter. For instance, in this way the representation of a geofence may be determined in such a way that it take into account specific characteristics of the respective positioning technique such that the geofence indicated by the determined representation of a geofence may allow trigger of a notification in case a mobile device applies this respective positioning technique and moves into the area (or boundaries) defined by the geofence indicated by the determined representation of a geofence.
For instance, the one or more positioning techniques may be a plurality of positioning techniques, and each positioning technique of the plurality of positioning techniques may be associated with a different wireless communication/transmission system, e.g. satellite based, or cellular based, or WiFi (e.g. based on any 802.11 standard), or Bluetooth based, or ZigBee based, or any other well suited wireless system. Then, as an example, a first positioning technique of the plurality of positioning techniques may be based on a first wireless communication/transmission system having a longer transmission range compared to the transmission range of a second wireless communication/transmission system which is used as basis for a second positioning technique of the plurality of positioning techniques. Then, as an example, if said representation of a geofence is indicative of a size of the geofence, the size of the geofence for the first communication system may be determined in action 210 to have a larger size compared to the size of the geofence associated with the second positioning technique, and/or, vice versa, the size of the geofence for the second communication system may be determined in action 210 to have a smaller size compared to the size of the geofence associated with the first positioning technique, in particular with respect to the same area-of-interest.
Thus, as an example, if a respective type of positioning technique is a cellular based positioning technique, e.g. based on GSM, UMTS, LTE or any other cellular communication system, and if said representation of a geofence is indicative of a size of the geofence, the size of the geofence may be determined in action 210 to have a larger size compared to the size of a geofence of another type of positioning technique which has a shorter range of wireless transmission compared to the cellular communication system of the type of cellular based positioning technique, e.g. a WiFi-based or Bluetooth based positioning technique.
Accordingly, in this way the representation of a geofence determined in action 210 for a respective positioning technique may be tailored and/or optimized with respect to the respective positioning technique based on the at least one parameter being associated with the respective positioning technique.
According to an example, said one or more positioning techniques are a plurality of different positioning techniques such that in action 210 for each positioning technique of the plurality of different positioning techniques, a representation of a geofence based on a plurality of parameters is determined, wherein at least one parameter of the plurality of parameters is indicative of an area-of interest geofence and at least one parameter of the plurality of parameters is indicative of a type of a respective positioning technique. For instance, the area-of interest 315, 325, 335 may be the same for each positioning technique of the plurality of positioning techniques in action 210. Accordingly, for such an area-of interest 315, 325, 335 for each positioning technique of the plurality of positioning techniques a specific representation of a geofence can be determined in action 210, wherein. Thus, as an example, a plurality of representations of a geofence are determined, wherein each representation of a geofence of the plurality of representations of a geofence is associated with a respective different positioning technique and may be associated with the same area-of-interest 315, 325, 335.
As an example, the one or more positioning techniques are one or more positioning techniques of:
Furthermore, for instance, the one or more cellular-based positioning techniques are one or more positioning techniques of: (i) a GSM-based positioning technique, and a 3G or higher based positioning technique, in particular UMTS or LTE or 5G or any cellular system beyond 5G.
Accordingly, in action 210, for the first positioning technique a representation of a geofence 410 is determined based on the area-of-interest 405 and the type of the first positioning technique, which is based on WiFi in this example. Furthermore, in action 210, for the second positioning technique a representation of a geofence 420 is determined based on the area-of-interest 405 and the type of the second positioning technique, which is based on 3G or higher in this example, and in action 210, for the third positioning technique a representation of a geofence 430 is determined based on the area-of-interest 405 and the type of the third positioning technique, which is based on 2G in this example. Each determined representation of a geofence 410, 420, 430 is determined in such a way that is surrounds the areas of interest.
Furthermore, the size of the representation of the geofence 410 associated with the first positioning technique is determined in action 210 to be smaller than the size of the representation of the geofence 420 associated with the second positioning technique, since in this example it can be assumed that the resolution of a position estimation based on the first positioning techniques is higher than the resolution of a position estimation based on the second positioning technique.
Similar, the size of the representation of the geofence 420 associated with the second positioning technique is determined in action 210 to be smaller than the size of the representation of the geofence 430 associated with the third positioning technique, since in this example it may be assumed that the resolution of a position estimation based on the second positioning techniques is higher than the resolution of a position estimation based on the third positioning technique.
Finally, the size of the representation of the geofence 430 associated with the third positioning technique is determined in action 210 to be larger than the size of the representation of the geofence 420 associated with the second positioning technique, since in this example it may be assumed that the resolution of a position estimation based on the third positioning techniques is lower than the resolution of a position estimation based on the second positioning technique.
Thus, for instance, said at least one parameter of the plurality of parameters associated with the respective positioning technique may be indicative of the type of the respective positioning technique and based on the type of the respective positioning technique, a resolution of a position estimation based on the respective positioning technique can be obtained (e.g. based on a knowledge database) which can then be used to determine the representation of the geofence 410, 420, 430, in particular the size of the geofence 410, 420, 430.
Although in
In action 450 of method 400 a size and/or a shape of the geofence is determined based on at least one radio coverage area associated with at least one transmitter related to the respective positioning technique, wherein, for instance, the determining a representation of a geofence 410, 420, 430 based on a plurality of parameters in action 210 may comprise said determining a size and/or shape of the geofence 410, 420, 430 based on at least one radio coverage area associated with at least one transmitter related to the respective positioning technique of action 450. Thus, for instance, action 450 may be performed for each positioning technique of the one or more positioning techniques mentioned with respect to action 210. For instance, such a transmitter of the at least one transmitter related to the respective positioning technique may represent an access point of the respective positioning technique, e.g. as explained above.
Thus, for instance, said at least one parameter of the plurality of parameters associated with the respective positioning technique may be assumed to indicative of the at least one radio coverage area associated with at least one transmitter related to the respective positioning technique, and, as an example, in particular of size and or shape of a radio coverage areas associated with each transmitter of one or more transmitters of the at least one transmitter related to the respective positioning technique.
As a first example rule of method 400, the radio coverage area associated with each of one or more transmitters of the at least one transmitter is at least partially within the area of interest. Thus, for instance, the respective positioning technique may comprise a plurality of transmitters, wherein each transmitter of the plurality of transmitters is associated with a radio coverage area which may define an area in which the radio signal transmitted by the respective transmitter can be received with a sufficient signal level. E.g., it may be checked whether there are one or more transmitters of the plurality of transmitters of the respective positioning technique, wherein each transmitter of the one or more transmitters of the plurality of transmitters of the respective positioning is associated with a radio coverage area being at least partially (or completely) within the area of interest such that this one or more transmitters can be identified to represent the one or more transmitters of the at least one transmitter being at least partially within the area of interest. Accordingly, one or more transmitters of the plurality of transmitters of the respective positioning technique may be determined, wherein each transmitter of the one or more transmitters of the plurality of transmitters of the respective positioning is associated with a radio coverage area being at least partially (or completely) within the area of interest. For instance, the one or more transmitters of the plurality of transmitters of the respective positioning technique may be determined in such a way that the radio coverage areas associated with all of the one or more transmitters completely cover the area-of-interest.
And/or, as a second example rule of method 400, the area of interest is at least partially within the radio coverage area associated with each of one or more transmitters of the at least one transmitter. E.g., it may be checked whether there are one or more transmitters of the plurality of transmitters of the respective positioning technique, wherein the area of interest at least partially (or completely) within the radio coverage associated with a transmitter of each transmitter of the one or more transmitters of the plurality of transmitters of the respective positioning such that this one or more transmitters can be identified to represent the one or more transmitters of the at least one transmitter, wherein the area of interest is at least partially within the radio coverage area of each transmitter of the one or more transmitters. Accordingly, one or more transmitters of the plurality of transmitters of the respective positioning technique may be determined, wherein the area of interest is at least partially (or completely) within the radio coverage area of each transmitter of the one or more transmitters of the plurality of transmitters of the respective positioning. For instance, the one or more transmitters of the plurality of transmitters of the respective positioning technique may be determined in such a way that the radio coverage areas associated with all of the one or more transmitters completely cover the area-of-interest.
And/or, as a third example rule of method 400, the radio coverage area associated with each of one or more transmitters of the at least one transmitter is within a predefined distance to the area of interest. I.e., in this example the radio coverage area associated with each of one or more transmitters of the at least one transmitter related to the respective positioning technique is not within the area of interest, but the nearest distance between the radio coverage area to the area of interest may be within the predefined distance. This may show the advantage if the radio coverage areas are quite small, e.g. in case of radio coverage areas in an urban areas, compared to radio coverage areas in rural areas, that the determined representation of a geofence is large enough around the area of interest such that detection of a mobile device moving into the geofence may be detected reliable (e.g. for longer location update intervals or higher speeds of the mobile device). In particular, this may hold for cellular based positioning techniques, but it could also hold for other positioning techniques. E.g., it may be checked whether there are one or more transmitters of the plurality of transmitters of the respective positioning technique, wherein each transmitter of the one or more transmitters of the plurality of transmitters of the respective positioning is associated with a radio coverage area which is not within the area of interest, but the nearest distance between the radio coverage area to the area of interest is within the predefined distance. Accordingly, one or more transmitters of the plurality of transmitters of the respective positioning technique may be determined, wherein each transmitter of the one or more transmitters of the plurality of transmitters of the respective positioning is associated with a radio coverage which is not within the area of interest, but the nearest distance between the radio coverage area to the area of interest is within the predefined distance.
It has to be understood that the first example rule, second example rule and third example rule of method 400 can be combined in any way, e.g. the first and second example rules, the first and third example rules, the second and third example rules, and first and second and third example rules, and further, that any of the first, second and third example rules may be taken alone.
Furthermore, as an example, said determining a size and/or a shape of the geofence based on the at least one radio coverage area associated with at least one transmitter related to the respective positioning technique in action 450 may be based on at least one statistical value calculated based on the at least one radio coverage area associated with at least one transmitter related to the respective positioning technique. E.g., at least one statistical value of the at least one statistical value may calculated periodically, i.e., it is updated.
For instance, said at least one statistical value is calculated based on the at least one radio coverage area associated with at least one transmitter related to the respective positioning technique comprises a median or mean size of a radio coverage area of the at least one radio coverage area.
Thus, as an example, for each radio coverage area of the at least one radio coverage area associated with at least one transmitter related to the respective positioning technique a statistical value may be calculated with represents the median or mean size of the radio coverage area. For instance, said median or mean size of the radio coverage area associated with at least one transmitter related to the respective positioning may be calculated periodically, i.e, it can be updated.
Or, as another example, said at least one statistical value calculated based on the at least one radio coverage area associated with at least one transmitter related to the respective positioning technique may represent the median or mean size of a radio coverage area (e.g. denoted as average radio coverage area) calculated based on a plurality of radio coverage areas associated with at least one transmitter related to the respective positioning technique, e.g. across some or all radio coverage areas associated with at least one transmitter related to the respective positioning technique. Then, this statistical value representing the median or mean size of a radio coverage area (e.g. denoted as average radio coverage area) associated with at least one transmitter related to the respective positioning technique may be used everywhere irrespective of the area-of-interest in questions.
For instance, said statistical value representing the median or mean size of a radio coverage area (e.g. denoted as average radio coverage area) associated with at least one transmitter related to the respective positioning may be calculated periodically, i.e., it can be updated.
For instance, as a non-limiting example,
As an example, the second example rule may be used to determine that transmitter 510 is a transmitter, wherein the area-of interest 505 is at least partially (e.g. in this case completely) within the radio coverage area 515 associated with this transmitter 510.
In this example, it may be assumed that only radio coverage area 515 is used as basis for determining the representation of the geofence in action 450, but it has to be noted that action 450 is not limited to exactly one radio coverage area 515. Then, the size and/or the shape of the geofence 520 determined in action 450 (e.g. also in action 210) is determined based on the radio coverage area 515 of transmitter 510 of the respective positioning technique.
For instance, if the shape of radio coverage area has an at least substantially circular shape the shape of the geofence could be determined to be at least substantially circular shape, or, if the shape of radio coverage area has an at least substantially ellipsoid shape the shape of the geofence could be determined to be at least substantially ellipsoid shape, or, a polygon shape of the geofence 520 may be determined wherein the polygon shape 520 is matched to the shape of the radio coverage area 515 of the transmitter 510 (e.g. as exemplarily shown in
Furthermore, as an example, the shape of the geofence 520′, 520″ may be determined to be a circular shape or an ellipsoid shape with a center point 501 within the area-of interest 505 (e.g. irrespective of the shape of the radio coverage area 515 of the transmitter 515), wherein the center point 501 may be in the center 501 of the area-of interest 505. Then, for instance, the size of the circular shaped (or ellipsoid shaped) geofence 520′ may be determined such that the determined geofence 520′ is within the radio coverage area 515 of the transmitter 510 (and e.g. the size of the geofence 520′ is maximized), or size of the circular shaped (or ellipsoid shaped) geofence 520″ may be determined such that radio coverage area 515 is completely within the determined geofence 520″ (and e.g. the size of the geofence 520″ is minimized).
It has to be understood that the size and shape of the radio coverage area 515 in
Furthermore, as another non-limiting example,
For instance, if the first and/or the second example rule is applied, transmitters 531, 541, 551 and 571 could be determined to be one or more transmitters, i.e. the area of interest 505 is at least partially (or completely) within the radio coverage area 530, 540, 550, 570 of each transmitter of the one or more transmitters 531, 541, 551 and 571 of the plurality of transmitters of the respective positioning technique (e.g. according to the second example rule), and/or, the radio coverage area 530, 540, 550, 570 of each transmitter of the one or more transmitters 531, 541, 551 and 571 of the plurality of transmitters is at least partially within the area-of-interest 505 (e.g. according to the first example rule).
In addition, as an example, radio coverage area may also be determined to be one of the one or more radio coverage areas used in action 450 based on the third example rule, since radio coverage area 560 associated with transmitter 561 may within a predefined distance to the area of interest 505. E.g., in this example the nearest distance 565 between the radio coverage area 560 associated with transmitter 561 and the area of interest 505 is within the predefined distance and thus the radio coverage area 560 associated with transmitter 561 may determined to be within a predefined distance to the area of interest 505. Then, for instance, the one or more transmitters used in action 450 may be transmitters 531, 541, 551, 561 and 571.
As a non-limiting example, the shape of the example geofence 580 determined in action 450 may depend on the shape resulting of aggregation (e.g. overlaying) of the radio coverage areas 530, 540, 550, 560, 570 of the one or more transmitters 531, 541, 551, 561 and 571 of the plurality of transmitters of the respective positioning technique, e.g. the shape of the geofence 580 may be determined to at least partially or substantially or completely match to the shape resulting of aggregation (e.g. overlaying) of the radio coverage areas 530, 540, 550, 560, 570 of the one or more transmitters 531, 541, 551, 561 and 571 of the plurality of transmitters of the respective positioning technique. E.g. the aggregation of the radio coverage areas 530, 540, 550, 560, 570 may be assumed to result in at least partially or substantially ellipsoid shape, and thus, as an example, an ellipsoid shape may be determined for geofence 580 in action 450, wherein, for instance, the center point of the ellipsoid shaped geofence 580 may be within the area-of interest 505, wherein the center point 501 of geofence 580 may be in the center 501 of the area-of interest 505. And/or, the size of the geofence 580 determined in action 450 may depend on the shape resulting of aggregation (e.g. overlaying) of the radio coverage areas 530, 540, 550, 560, 570 of the one or more transmitters 531, 541, 551, 561 and 571 of the plurality of transmitters of the respective positioning technique.
As a further non-limiting example, the size of the example geofence 580 determined in action 450 may depend on a size of aggregation (e.g. overlaying) of the radio coverage areas 530, 540, 550, 560, 570 of the one or more transmitters 531, 541, 551, 561 and 571 of the plurality of transmitters of the respective positioning technique.
For instance, the size of the geofence 580′, 580″ may be determined such that the determined geofence 580″ at least substantially (or completely) covers each radio coverage area 530, 540, 550, 560, 570 of the one or more transmitters 531, 541, 551, 561 and 571 of the plurality of transmitters of the respective positioning technique is within the determined geofence 580″ (and e.g. the size of the geofence 580″ may be minimized). Thus, for instance, of the size of the geofence 580′, 580″ may be selected to be a circular shape (however, any other well-suited shape, e.g. ellipsoid or polygon etc., may be selected), then the radius 581″ of the geofence 580″ may be selected to cover even the outer circumference of radio coverage area 560.
For instance, the size of the geofence 580′ may be determined such that the determined that the geofence 580′ is not outside an area defined by the aggregation of each radio coverage area 530, 540, 550, 560, 570 of the one or more transmitters 531, 541, 551, 561 and 571 of the plurality of transmitters of the respective positioning technique and is further still around the area-of-interest, wherein in particular, the size of the geofence 580′ may be maximized but still such that the geofence 580′ is not outside an area defined by the aggregation of each radio coverage area 530, 540, 550, 560, 570 of the one or more transmitters 531, 541, 551, 561 and 571 of the plurality of transmitters of the respective positioning technique. Thus, for instance, of the size of the geofence 580′ may be selected to be a circular shape (however, any other well-suited shape, e.g. ellipsoid or polygon etc., may be selected), then the radius 581′ of the geofence 580′ may be determined to be maximized but to exceed the outer circumference of (e.g. nearest) radio coverage area 570.
As an example, said size and/or shape of the geofence determined based on at least one radio coverage area associated with at least one transmitter related to the respective positioning technique (action 450) may be determined based on a database comprising information regarding the at least one transmitter related to the respective positioning technique. E.g., said information in the database may comprise the at least one statistical value, which may be updated peridiocally or on regular basis. For instance, for a respective positioning technique there may be stored for at least one transmitter the typical shape and/or size of this transmitter, and/or, there may be stored a typical shape and/or size of a transmitter based on a average values of a plurality of transmitters of the respective positioning technique. Accordingly, a kind of knowledge database may be used to collect information regarding typical shapes and sizes of transmitters (e.g. APs) for each positioning technique of the one or more positioning techniques.
Method 600 includes defining an area-of interest in action 610. For instance, this area-of-interest may be that area-of-interest used in action 210 of method 200. As an example, the area-of-interest may be defined in response to a user interaction with apparatus 100, e.g. via an interface of apparatus 100.
Then, in action 620, for a respective positioning technique of the one or more different positioning techniques, a representation of a geofence is determined at least partially based on a plurality of parameters, wherein at least one parameter of the plurality of parameters is indicative of the area-of interest geofence (defined in action 610) and at least one parameter of the plurality of parameters is associated with the respective positioning technique of the one or more positioning techniques, e.g. as described with respect to action 210 and/or to action 450.
In action 630 it may be checked whether there is a further positioning technique, and if yes, method 600 may proceed at action 620 with this further positioning technique as respective positioning technique. In this way, for the area-of-interest defined in action 610, a representation of a geofence may be determined in action 620 for each positioning technique of the one or more positioning techniques.
Apparatus 100, methods 200, 400 and 600 in
Apparatus 700 could be a server or any other kind of client like a mobile or stationary device. If a plurality of apparatus are used, each apparatus may comprise a processor 701, and linked to processor 701, a memory 702, wherein memory 702 at least partially stores computer program code for selecting a representation of a geofence from a plurality of representations of a geofence based on a type of a positioning technique. For instance, said plurality of apparatus may represent servers in a cloud interaction together. Apparatus 100 could equally be a component, like a chip, circuitry on a chip or a plug-in board, for any mobile or stationary device. Optionally, apparatus 100 could comprise various other components, like a data interface configured to enable an exchange of data with separate devices, a user interface like a touchscreen, a further memory, a further processor, etc.
An operation of at least one apparatus will now be described with reference to the flow chart 720 of
In action 730 of method 720, a representation of a geofence is selected from a plurality of representations of geofences based on a type of a positioning technique. For instance, said plurality of representations geofences may be associated with the same area-of-interest 315, 325, 335, 405, 505, and, as an example, plurality of representations of a geofence may have been determined by means of any of the methods and/or apparatuses of the first aspect of the invention, e.g. based on method 200, 450 and/or 600.
Thus, for instance, each representation of the plurality of representations is associated with a different type of a positioning technique of a plurality of positioning techniques.
Furthermore, as an example, the type of a positioning technique used in action 730 may be determined based on the positioning technique applied by a mobile device. This mobile device may be any mobile device explained with respect to first aspect of the invention. Thus, the representation of the geofence can be selected to match to the positioning techniques applied by the mobile device such that the advantages explained with respect to the first invention may be achieved.
