Description

TECHNICAL FIELD

The subject disclosure relates to communication systems and, more particularly, to determining site locations using crowd sourced propagation delay and location data.

BACKGROUND

Advances in cellular phone and related network technology (e.g., microprocessor speed, memory capacity, data transfer bandwidth, software functionality, and the like) have generally contributed to increased cellular application in various settings. For example, today's cellular phones can perform many functions previously reserved for personal computers or other devices, such as web browsing, picture/video shooting, picture/video sharing, instant messaging, file sharing, and the like. As cellular phone capabilities increase, which can also increase demand for the capabilities, networks and protocols are developed to effectively support the capabilities. For example, while global system for mobile communications (GSM) was sufficient to handle functionality of cellular phones a few years ago, other technologies, such as universal mobile telecommunications system (UMTS), which is based from the third generation (3G) standard, have been developed to accommodate larger transfer rates between device and network.

More recently, fourth generation (4G) technologies have been developed, such as third generation partnership project (3GPP) long term evolution (LTE), worldwide interoperability for microwave access (WiMAX), and the like. These technologies provide even further increases in data throughput between mobile device and network, which allows for a vast array of supported device functionalities. In order to support the rapid growth and development of cellular phones and related network technologies, service providers maintain extensive infrastructures. For instance, the network infrastructure of large service providers can include tens of thousands cell site locations.

Service providers may desire to employ a cell site location to facilitate network services, such as, locating a mobile device within a wireless network. Typically, the cell site location can be determined and/or recorded by a person associated with the service provider. For instance, a network engineer may record the location of the cell site in a database during installation. If the person inaccurately records or determines the location of a cell site, then the service provider may be unable to rely on the recorded location of the cell site to facilitate the network services.

The above-described deficiencies are merely intended to provide an overview of some of the problems of conventional systems and techniques, and are not intended to be exhaustive. Other problems with conventional systems and techniques, and corresponding benefits of the various non-limiting embodiments described herein may become further apparent upon review of the following description.

The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the various embodiments. This summary is not an extensive overview of the various embodiments. It is intended to neither identify key or critical elements of the various embodiments nor delineate the scope of the various embodiments. Its sole purpose is to present some concepts of the various embodiments in a simplified form as a prelude to the more detailed description that is presented later. It will also be appreciated that the detailed description may include additional or alternative embodiments beyond those described in this summary.

Systems and methods are provided for site location determination using crowd sourced propagation delay and location data. A propagation delay component receives a set of propagation delay measurements based on communication signals exchanged by a mobile device and an access point. A user equipment location component receives a location of the mobile device, and a combination component combines the set of propagation delay measurements and the location into a set of location data. An access point location component determines a set of intersecting locations between the set of location data and additional sets of location data, and determines a location of the access point based on the set of intersecting locations.

In accordance with one aspect, a system is provided that includes at least one memory storing computer-executable instructions, and at least one processor, communicatively coupled to the at least one memory, which facilitates execution of the computer-executable instructions to at least receive propagation delay measurements based on communication signals exchanged by a mobile device and an access point, receive a location of the mobile device, and determine an estimated location of the access point based on the propagation delay measurements and the location of the mobile device.

In accordance with another aspect, a method is provided that includes receiving, by a system including a processor, propagation delay measurements based on communication signals exchanged by a mobile device and an access point, receiving, by the system, a location of the mobile device, generating, by the system, a first set of location data based at least in part on the propagation delay measurements and the location of the mobile device, comparing, by the system, the first set of location data and additional sets of location data corresponding, respectively, to a set of disparate mobile devices.

In accordance with yet another aspect, a computer readable storage medium is provided that includes computer executable instructions that, in response to execution, cause a computing system including at least one processor to perform operations, including receiving a location of a first mobile device and a first set of propagation delay measurements for communication signals exchanged by the first mobile device and an access point, generating a first set of location data using the first set of propagation delay measurements and the location of the first mobile device, receiving a location of a second mobile device and a second set of propagation delay measurements for communication signals exchanged by the second mobile device and the access point, generating a second set of location data using the second set of propagation delay measurements and the location of the second mobile device, determining a set of intersecting locations between the first set of location data and the second set of location data, and identifying an estimated location of the access point based at least in part on the set of intersecting locations.

To the accomplishment of the foregoing and related ends, the various embodiments, then, comprise one or more of the features hereinafter fully described. The following description and the annexed drawings set forth in detail certain illustrative aspects of the various embodiments. However, these aspects are indicative of but a few of the various ways in which the principles of the various embodiments may be employed. Other aspects, advantages and novel features of the various embodiments will become apparent from the following detailed description of the various embodiments when considered in conjunction with the drawings.

FIG. 1 illustrates an example wireless communication system 100 in accordance with various aspects described in this disclosure. The wireless communication system 100 (e.g., network) can support a plurality of subscribers (e.g., mobile devices, etc.). By way of example, the system 100 provides communication for multiple cells 102A-102C, with each cell being serviced by a corresponding access point (AP) 104 (such as APs 104A-104C). Each cell may be further divided into one or more sectors (e.g. to serve one or more frequencies). Various access terminals (ATs) 106, including ATs 106A-106C, also known interchangeably as user equipment (UE) or mobile devices, are dispersed throughout the system.

It can to be appreciated that the wireless communication system 100 can provide service over a geographic region. For example, the cells 102A-102C may cover a few blocks, square acres, or square miles. In addition, it can be appreciated that a virtually infinite number of cells 102 can be employed to cover a large geographic region, such as a state, country, continent, etc. In this way, a single service provider can enable virtually uninterrupted wireless communication service across a large geographic region. The service provider may desire to determine and/or employ a location of an AP (e.g., a cell site location) for a set of network services. The set of network services can include but are not limited to network locating, network optimizing, and/or network modeling. For example, the location of a UE 106B can be determined by identifying one or more APs (e.g., AP 104B) serving (or near) the UE 106B. However, if the location of the AP 104B is not accurately known to the service provider, then the location of the UE 106B cannot be accurately determined based on the location of the AP 104B. The location of the AP 104B may not be accurately known to the service provider, for example, if the location of the AP 104B is determined and/or recorded incorrectly at a time of installation, or if the AP 104B has been relocated.

In one implementation, the system 100 determines a location of an AP (e.g., AP 104B) based on a set of location data for a UE (e.g., UE 106B). The set of location data for the UE (location data) can include but is not limited to a location of a UE (UE location), and a set of propagation delay measurements for communications between the UE and the AP (propagation delay measurements). For example, a UE location can be determined using a global positioning system (GPS) and/or an assisted GPS (AGPS), and the system 100 can obtain or determine propagation delay measurements for communications from the UE 106B to the AP 104B. Based in part on the UE location and the propagation delay measurements, the system 100 can calculate, identify, or otherwise determine an estimated location for the AP 104B (discussed in greater detail with reference to FIG. 5). In addition, the system 100 can analyze or compare additional sets of location data for different UEs (e.g., UE 106A) against the location data for the UE 106B to enhance the accuracy of the determined estimated location for the AP 104B (discussed in greater detail with reference to FIG. 6). For example, the system 100 can crowd source, using a plurality of UEs, a set of sets of location data, and based on intersecting locations or overlaps of locations in the respective sets of location data determine a location of the AP 104B.

Turning now to FIG. 2, illustrated is a system 200 for site location determination using crowd sourced propagation delay and location data in accordance with various aspects described in this disclosure. The system 200 includes a network 202 (e.g., system 100) and a cell site component 204. The cell site component 204 determines a location of an access point 214 (AP 214) associated with the network 202 using crowd sourced propagation delay and location data. The cell site component 204 includes a propagation delay component 206, a user equipment (UE) location component 208, a combination component 209, and an access point (AP) location component 210.

The propagation delay component 206 obtains, acquires, or otherwise receives a set of measurements of propagation delay between a mobile device (UE) and an AP (propagation delay measurements). For example, the network 202 can determine propagation delay measurements for a UE 212A and an AP 214 during radio link establishment, and the propagation delay component 206 can receive the propagation delay measurement, e.g., via the network 202. The propagation delay measurements include measurements of lengths of time required for a signal to travel from a sender (e.g., UE) to a receiver (e.g., AP), and can be employed to determine a distance (e.g., maximum distance or minimum distance) between the sender and the receiver (discussed in greater detail with reference to FIG. 5). For example, the propagation delay measurements can include a minimum propagation delay and a maximum propagation delay.

The UE location component 208 acquires, determines, or otherwise receives a location of a UE (UE location). For example, a set of location based services (LBS) can be employed to determine a UE location for a UE 212A. The set of LBS can include but are not limited to global positioning systems (GPS), and/or assisted global positing systems (AGPS). For instance, the network 202 can request the UE 212A to employ an AGPS associated with the UE 212A to determine a location of the UE 212A. In response to the request, the UE 212A provides a set of AGPS measurements, and the UE location component 208 receives the set of AGPS measurements, e.g., via the network 202. The AGPS measurements can provide a fixed reference point (e.g., latitude and longitude) that can be used to facilitate a determination of a location of an access point (AP).

The combination component 209 combines, joins, or otherwise includes the propagation delay measurements and the UE location in a set of location data. In addition, the combination component 209 appends, attaches, or otherwise associates a time stamp and/or UE identifier to the set of location data. For example, propagation delay measurements and a UE location received at a first time (e.g., 6:00 AM on Apr. 4, 2013) and associated with a first UE can be included in a first set of location data, and a time stamp corresponding to the first time and/or an identifier of the first UE can be associated with the first set of location data. It can be appreciated that although the sets of location data 216 are illustrated as being maintained in a data store 218, such implementation is not so limited. For example, the sets of location data 216 can be maintained in a different location, and the cell site component 204 can access the sets of location data 216, for example, via a network connection.

The AP location component 210 calculates, identifies, or otherwise determines a location of an AP based in part on sets of location data 216 corresponding to the AP. For example, in one implementation, the AP location component 210 determines a location of an AP by determining overlapping or intersecting locations included in respective sets of location data 216 associated with the AP. For instance, if a first set of location data and a second set of location data include an overlapping (intersecting) location, then the AP location component 210 can determine that the overlapping location is an estimated location of the AP. It can be appreciated that the more sets of location data corresponding to an AP that include an overlapping location, the greater the probability that the overlapping location includes the AP.

In addition, it can be appreciated that although the cell site component 204 is illustrated as being a stand-alone component, such implementation is not so limited. For example, the cell site component 204 can be included in the network 202. As an additional or alternative example, the cell site component 204 can be included a probe network. For instance, if the network 202 is a third generation partnership project (3GPP) network, then the cell site component 204 can be included in a probe network that captures or receives control plane level data, including encoded 3GPP messages, radio access network application part (RANAP) messages, and/or node B application part (NBAP) messages including propagation delay measurements and/or UE locations, and decodes the messages (e.g., 3GPP, RANAP, NBAP).

FIG. 3 illustrates an example propagation delay component 206 in accordance with various aspects described in this disclosure. As discussed, the propagation delay component 206 receives a set of measurements of propagation delay between a mobile device 212 (UE 212) and an AP 214 (propagation delay measurements). For example, the network 202 can determine propagation delay measurements for the UE 212 and the AP 214 during radio link establishment, and the propagation delay component 206 can receive the propagation delay measurements, e.g., via the network 202. The propagation delay component 206 in FIG. 3 includes a minimum delay component 302 (min delay component 302), a maximum delay component 304 (max delay component 304), and a compensation component 306.

The min delay component 302 determines or receives a minimum propagation delay between the UE 212 and the AP 214. For example, the minimum propagation delay measurement can be included in an encoded message, and the min delay component 302 can decode the message and extract the minimum propagation delay measurement. As an additional or alternative example, the min delay component 302 can determine a minimum propagation delay measurement included in a message based on a set of minimum propagation delay criteria. The minimum propagation delay criteria can include but are not limited to having a value that is less than other propagation delay measurements included in a message.

The max delay component 304 determines or receives a maximum propagation delay between the UE 212 and the AP 214. For example, the maximum propagation delay measurement can be included in an encoded message, and the max delay component 304 can decode the message and extract the maximum propagation delay measurement. As an additional or alternative example, the max delay component 304 can determine a maximum propagation delay measurement included in a message based on a set of maximum propagation delay criteria. The maximum propagation delay criteria can include but are not limited to having a value that is greater than other propagation delay measurements included in a message.

The propagation delay measurements include measurements of lengths of time required for signals to travel from a sender (e.g., UE 212) to a receiver (e.g., AP 214), and can be employed to determine a distance (e.g., maximum distance or minimum distance) between the sender and the receiver, when the speed of the signal is known. For example, the network 202 can measure the propagation delay based on a predetermined propagation delay measurement unit (e.g., chips), and each unit can correspond to a predetermined distance (e.g., 78 meters). For instance, if the minimum propagation delay between the UE 212 and the AP 214 is six chips, then the minimum distance between the UE 212 and AP 214 is 234 meters (e.g., 6 chips×78 meters).

The compensation component 306 determines if the propagation delay measurements include a compensation factor. For example, a propagation delay measurement may be determined using base equipment 308 communicatively coupled to an antenna 310 by a connection 312 (e.g., wire, cable, etc.) having a length, L, where L can be a positive real number. If the length of the connection 312, L, from the antenna 310 to the base equipment 308 (e.g., height of the AP tower) is 100 meters, and a propagation delay measurement is determined based on a length of 234 meters without accounting for L, then the determined propagation delay measurement may be incorrect. The compensation component 306 can determine a set of vendor information (e.g., vendor identifier, part number, etc.) for AP 214, the antenna 310, and/or base equipment 308, and, based on the vendor information, determine if the propagation delay measurements include a compensation factor. If the propagation delay measurements do not include a compensation factor, then the compensation component 306 alters, modifies, or otherwise corrects the propagation delay measurements based on L.

Referring to FIG. 4, illustrated is an example access point location component 210 in accordance with various aspects described in this disclosure. As discussed, the access point (AP) location component 210 determines a location of the AP based on sets of location data 216 associated with the AP. The AP location component 210 in FIG. 4 includes a UE area component 402, a comparison component 404, and a flagging component 406. The UE area component 402 generates, calculates, or otherwise determines UE location areas based on respective sets of location data included in the sets of location data 216 (e.g., propagation delay measurements and UE locations). For example, the UE area component 402 can generate a circle based on a first set of location data. The circle can have a minimum radius corresponding to a minimum propagation delay measurement, a maximum radius corresponding to a maximum propagation delay measurement, and a center at a location corresponding to a UE location.

The comparison component 404 determines estimated locations of an AP (estimated AP locations) based on intersecting locations of UE location areas (e.g., circles) corresponding to respective sets of location data. For instance, estimated AP locations can be determined at a set of locations where a first circle and a second circle intersect. The estimated AP locations may have some error based at least in part on the difference between the minimum radius and maximum radius of the first circle and second circle, and/or multiple intersecting locations of the first circle and second circle. The comparison component 404 can compare the intersecting locations with a set of additional information to reduce the error. The set of additional information can include but is not limited to a recorded location of an AP, and/or a set of geographical/topographical data. For instance, if a previously recorded location of an AP corresponds to a first estimated AP location, then the comparison component 404 can bias (e.g., weight, rank, flag, etc.) the first estimated AP location as likely corresponding to an actual AP location. As an additional or alternative example, if a set of geographical data indicates that a second estimated AP location is in an undesirable location (e.g., a lake), then the comparison component 404 can bias (e.g., weight, rank, flag, etc.) the second estimated AP location as not likely corresponding to an actual AP location.

The comparison component 404 determines whether an estimated AP location satisfies an error threshold. For example, the error threshold can include a size (e.g., meters, square meters, etc.) of the estimated AP location. For instance, the error threshold can be Y square meters, where Y is a real number. If the estimated AP location satisfies the error threshold, then the comparison component 404 flags, sets, or otherwise determines the estimated AP location as an actual AP location. The cell site component 204 can provide the actual AP location to a network (e.g., network 202) for a set of network services. The set of network services can include but are not limited to network locating, network optimizing, and/or network modeling. If none of the estimated AP locations satisfy the error threshold, then the comparison component 404 can instruct the cell site component 204 to increase the sample size (e.g., sets of location data 216).

If the comparison component 404 determines an actual AP location for an AP, then the cell site component 204 can stop, suspend, or otherwise reduce acquisition of location data for the AP. The flagging component 406 randomly and/or at predetermined intervals obtains, acquires, or otherwise receives additional sets of location data, and compares the additional sets of location data to the determined actual AP location. Based on the comparison, the flagging component 406 determines if respective sets of location data in the additional sets of location data satisfy an accuracy threshold. For example, the accuracy threshold can include a predetermined distance from the determined actual AP location. For instance, if an additional set of location data indicates a location of the AP as being 600 meters away from the determined actual AP location, then the additional set of location data may not satisfy the accuracy threshold. If a quantity of sets of location data in the additional sets of location data not satisfying the accuracy threshold satisfies a flagging threshold, then the flagging component 406 can flag the determined actual AP location as being potentially inaccurate, and/or set the determined actual AP location as an estimated AP location. The flagging threshold can include, for example, a predetermined quantity of sets of location data not satisfying the accuracy threshold, and/or a predetermined quantity of sets of location data not satisfying the accuracy threshold determined within a predetermined period of time. For instance, a location of an AP may have been moved during an upgrade of the network, and the flagging component 406 can flag a previously determined actual AP location for the AP as being potentially inaccurate.

FIG. 5 illustrates a non-limiting example of a system 500 for a user equipment location in accordance with various aspects described in this described in this disclosure. The system 500 includes a mobile device 212 (UE 212). As discussed, propagation delay measurements for communications between the UE 212 and an access point (AP) can be received (e.g., using the propagation delay component 206). For example, a network can determine propagation delay measurements for the UE 212 during radio link establishment. The propagation delay measurements can include a minimum propagation delay measurement 502, and a maximum propagation delay measurement 504. The propagation delay measurements are measurements of lengths of time required for a signal to travel from a sender (e.g., AP) to a receiver (e.g., UE), and a distance (e.g., maximum distance or minimum distance) between the sender and the receiver can be determined based on the propagation delay measurements. For instance, if the signal travels at a speed of X meters/second, and the propagation delay measurement is Y seconds, then it can be determined that the sender and receiver are X* Y meters apart, where X and Y are positive real numbers.

In addition, a location of the UE 212 (UE location) can be received (e.g., using the UE location component 208). For example, a set of location based services (LBS) included in a network can be used to determine the UE location for the UE 212. The set of LBS can include but are not limited to global positioning systems (GPS), and/or assisted global positing systems (AGPS). The GPS and/or AGPS measurement can provide a fixed reference point (e.g., latitude and longitude) to determine the location of the AP. A circle 510 having a minimum radius 506 corresponding to a minimum propagation delay measurement 502, a maximum radius 508 corresponding to a maximum propagation delay measurement 504, and a center at a location corresponding to the UE location for the UE 212 can be generated (e.g., using the AP location component 210). The AP can be potentially located between the minimum radius 506 and maximum radius 508 of the circle 510 (e.g., estimated AP location).

FIG. 6 illustrates a non-limiting example of a system 600 for locating an access point in accordance with various aspects described in this disclosure. The system 600 includes a circle corresponding to a first set of location data 602 (circle 602), a circle corresponding to a second set of location data 604 (circle 604), and a circle corresponding to a third set of location data 606 (circle 606). The circles 602-606 are associated with a first access point (AP). An estimated location of the first AP (estimated AP location) can be determined based on overlapping locations or intersecting locations of the circles 602-606. As discussed, the estimated AP location may have some error based at least in part on the difference between the minimum radius and maximum radius of circles 602-606, and/or multiple intersecting locations of the circles 602-606. For example, the first circle 602 and second circle 604 intersect at a first location 608 and a second location 610. In addition, the size of the intersecting locations (e.g., error) can be based in part on the minimum radius and maximum radius of the circles 602 and 604. The intersecting locations can be compared against a set of additional information to reduce the error. The set of additional information can include but is not limited to a recorded location of an AP, and/or geographical/topographical data. For instance, if the recorded location of the AP corresponds to the second location 610, then the second location 610 can be biased (e.g., weighted, ranked, etc.) as more likely corresponding to the actual AP location than the first location 608.

A greater quantity of circles (e.g., sets of location data) can enable greater accuracy in determining an estimated AP location. For example, the third circle 606 intersects the first circle 602 and second circle 604 at the second location 610, and does not intersect the first circle 602 and second circle 604 at the first location 608. In addition, a size or area of the intersection (e.g., overlap) of the third circle 606 with the first circle 602 and second circle 604 at the second location 610 is less than a size or area of the intersection of the first circle 602 and second circle 604 at the second location 610. If the estimated AP location satisfies a predetermined error threshold, then the estimated AP location can be determined as an actual location of the AP (AP) (e.g., using the comparison component 404), and made available for network locating, optimizing, and/or modeling. If the estimated AP location does not satisfy the predetermined error threshold, then the sample size can be increased. For example, additional sets of location data can be received or determined and compared against the circles 602-606.

In view of the example systems described supra, methods that may be implemented in accordance with the disclosed subject matter may be better appreciated with reference to the flow charts of FIGS. 7-9. While for purposes of simplicity of explanation, the methods are shown and described as a series of blocks, it can be understood and appreciated that the claimed subject matter is not limited by the order of the blocks, as some blocks may occur in different orders and/or concurrently with other blocks from what is depicted and described herein. Moreover, not all illustrated blocks may be required to implement the methods described hereinafter.

Turning now to FIG. 7, is an example methodology 700 for site location determination using crowd sourced propagation delay and location data in accordance with various aspects described in this disclosure. At 702, a set of propagation delay measurements between a UE and an AP can be received (e.g., using the propagation delay component 206). For example, a network can determine propagation delay measurements for a UE and an AP during radio link establishment. The propagation delay measurements include measurements of lengths of time required for a signal to travel from a sender (e.g., UE) to a receiver (e.g., AP), and can be employed to determine a distance (e.g., maximum distance or minimum distance) between the sender and the receiver (discussed in greater detail with reference to FIG. 5). For example, the propagation delay measurements can include a minimum propagation delay, and/or a maximum propagation delay.

At 704, a location of a UE (UE location) can be received (e.g., using the UE location component 208). For example, a set of network location based services (LBS) can be employed to determine a UE location. The set of LBS can include but are not limited to global positioning systems (GPS), and/or assisted global positing systems (AGPS). The GPS and/or AGPS measurements provide a fixed reference point (e.g., a latitude and a longitude) to determine the location of an access point (AP).

At 706, a first set of location data can be generated using the set of propagation delay measurements and the UE location (e.g., using the combination component 209). For example, the set of propagation delay measurements and the UE location can be included in a set of location data, and a time stamp and/or UE identifier can be associated with the set of location data. For instance, if the propagation delay measurements and the UE locations were received at a first time (e.g., 6:00 AM on Apr. 4, 2013) and are associated with a first UE, then the propagation delay measurements and the UE locations can be included in the first set of location data, and a time stamp corresponding to the first time and/or an identifier of the first UE can be associated with the first set of location data.

At 708, a set of intersecting locations between the first set location data and additional sets of location data are determined (e.g., using the comparison component 404). For example, circles corresponding to the first set of location data and the additional sets of location data can be compared, and a set of intersecting locations (e.g., overlaps) between the circles can be determined based on the comparison. The circles can have a minimum radius corresponding to a minimum propagation delay measurement, a maximum radius corresponding to a maximum propagation delay measurement, and a center location corresponding to a UE location.

At 710, an estimated location of an AP can be determined based on the set of intersecting locations (e.g., using the comparison 404). For example, an intersection included in the set of intersecting locations that has a greatest quantity of overlapping sets of location data can be determined as the estimated location of the AP. At 712, a determination can be made whether the estimated location of the AP satisfies an error threshold (e.g., using the comparison component 404). At 714, if it is determined that the estimated location of the AP satisfies the error threshold (Y at 712), then the estimated location can be set as a determined actual location of the AP (e.g., using the AP location component 210). The determined actual location of the AP can be made available for a set of network services, including but not limited to network locating, network optimizing, and/or network modeling. Returning to 712, if it is determined that the estimated location of the AP does not satisfy the error threshold (N at 712), then the methodology returns to 708, and intersecting locations between the first set of intersecting locations and other additional sets of location are determined. Comparing an estimated AP location against a greater quantity of sets of location data (e.g., sample size) may increase the accuracy of the estimated AP location determination.

Turning now to FIG. 8, is an example methodology 800 for site location determination using crowd sourced propagation delay and location data in accordance with various aspects described in this disclosure. At 802, a determined actual location can be compared against sets of additional location data (e.g., using the flagging component 406). For example, the determined actual location can be compared against sets of additional location data randomly and/or at predetermined intervals, (e.g., monthly, quarterly, etc.).

At 804, a determination can be made whether a quantity of location data not satisfying an accuracy threshold satisfies a flagging threshold (e.g., using the flagging component 406). For example, if a set of location data included the additional sets of location data indicates an estimated location of the AP as being 600 meters away from the determined actual AP location, then the location data may not satisfy the accuracy threshold.

At 806, if it is determined that the quantity of location data not satisfying the accuracy threshold satisfies the flagging threshold (Y at 804), then the determined actual location of the AP can be flagged as being potentially inaccurate (e.g., using the flagging component 406). For instance, a location of an AP may have been moved during an upgrade of a network, and a previously determined actual location for the AP can be flagged as being potentially inaccurate. Returning to 804, if it is determined that the quantity of location data not satisfying the accuracy threshold does not satisfy the flagging threshold (N at 804), then the methodology returns to 802.

FIG. 9 is an example methodology 900 for site location determination using crowd sourced propagation delay and location data in accordance with various aspects described in this disclosure. At 902, a set of propagation delay measurements for communications between a UE and an AP are received (e.g., using the propagation delay component 206). For example, a network can determine propagation delay measurements for a UE and an AP during radio link establishment. The propagation delay measurements include measurements of lengths of time required for a signal to travel from a sender (e.g., UE) to a receiver (e.g., AP), and can be employed to determine a distance (e.g., maximum distance or minimum distance) between the sender and the receiver (discussed in greater detail with reference to FIG. 5). For example, the propagation delay measurements can include a minimum propagation delay, and a maximum propagation delay.

At 904, a determination can be made whether the set of propagation delay measurements include a compensation factor (e.g., using the compensation component 306). For example, a propagation delay measurement may be determined using base equipment communicatively coupled to an antenna of an AP by a connection (e.g., wire, cable, etc.) having a length, L, where L is a positive real number. If the length of the connection, L, from the antenna to the base equipment (e.g., height of the AP tower) is 100 meters, and the propagation delay measurement is determined based on a distance of 234 meters (e.g., from the UE to the base equipment) without accounting for L, then the determined propagation delay measurement may be incorrect. In one implementation, a set of vendor information (e.g., vendor identifier, part number, etc.) for an AP, the antenna, and/or base equipment, can be determined and, based on the vendor information, a determination can be made whether the set of propagation delay measurements include a compensation factor.

At 906, if it is determined that the set of propagation delay measurements do not include a compensation factor (N at 904), then the set of propagation delay measurements are corrected based on L (e.g., using the compensation component 306). Returning to 904, if it is determined that the set of propagation delay measurements include a compensation factor (Y at 904), then the methodology terminates.

As an example, processor 1035 can be configured to execute, at least in part, instructions in multimode operation chipset(s) that afford multimode communication through mobile 1005 such as concurrent or multitask operations of two or more chipset(s). As another example, processor 1035 can facilitate mobile 1005 to receive and convey signaling and content(s) (e.g., various data flows) that are part of an active management act initiated by a subscriber that operates mobile 1005, or an approval cycle associated with auxiliary subscribers (e.g., secondary subscriber, tertiary subscriber . . . ). Moreover, processor 1035 facilitates mobile 1005 to process data (e.g., symbols, bits, or chips) for multiplexing/demultiplexing, modulation/demodulation, such as implementing direct and inverse fast Fourier transforms, selection of modulation rates, selection of data packet formats, inter-packet times, etc. Memory 1055 can store data structures (e.g., metadata); code structure(s) (e.g., modules, objects, classes, procedures) or instructions; network or device information like policies and specifications, attachment protocols; code sequences for scrambling, spreading and pilot (e.g., reference signal(s)) transmission; frequency offsets, cell IDs, and so on.

Generally, mobile network platform 1110 can include components, e.g., nodes, gateways, interfaces, servers, or platforms, that facilitate both packet-switched (PS) (e.g., internet protocol (IP), frame relay, asynchronous transfer mode (ATM)) and circuit-switched (CS) traffic (e.g., voice and data) and control generation for networked wireless communication. In an aspect, as described above, component within PS domain of network platform 1110 can be employed to effect communication in accordance with aspects described herein.

With respect to CS communication, mobile network platform 1110 includes CS gateway node(s) 1112 which can interface CS traffic received from legacy networks such as telephony network(s) 1114 (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a SS7 network 1116. Circuit switched gateway node(s) 1112 can authorize and authenticate traffic (e.g., voice) arising from such networks. Additionally, CS gateway node(s) 1112 can access mobility, or roaming, data generated through SS7 network 1116; for instance, mobility data stored in a visitation location register (VLR), which can reside in memory 1120. Moreover, CS gateway node(s) 1112 interfaces CS-based traffic and signaling and gateway node(s) 1122. As an example, in a 3GPP UMTS network, CS gateway node(s) 1112 can be embodied, at least in part, in gateway GPRS support node(s) (GGSN).

In addition to receiving and processing CS-switched traffic (e.g., content(s) that can be part of a content(s) transmitted by a service provider) and signaling, PS gateway node(s) 1122 can authorize and authenticate PS-based data sessions with served mobile devices, non-mobile devices, and access points. Data sessions can include traffic, or content(s), exchange with networks external to the mobile network platform 1110, such as wide area network(s) (WANs) 1130 or service network(s) 1140; it should be appreciated that local area network(s) (LANs) 1150 can also be interfaced with mobile network platform 1110 through PS gateway node(s) 1122. Packet-switched gateway node(s) 1122 generates packet data contexts when a data session is established. To that end, in an aspect, PS gateway node(s) 1122 can include a tunnel interface (e.g., tunnel termination gateway (TTG) in 3GPP UMTS network(s) (not shown)) which can facilitate packetized communication with disparate wireless network(s), such as network platform and associated radio access network, Wi-Fi networks. It should be further appreciated that the packetized communication can include multiple flows that can be generated through service (e.g., provisioning) and application server(s) 1160. It is to be noted that in 3GPP UMTS network(s), PS gateway node(s) 1122 (e.g., GGSN) and tunnel interface (e.g., TTG) comprise a packet data gateway (PDG).

The mobile network platform 1110 also includes serving node(s) 1170 that convey the various packetized flows of data streams (e.g., content(s) or signaling directed to a subscribed data), received through PS gateway node(s) 1122. As an example, in a 3GPP UMTS network, serving node(s) 1170 can be embodied in serving GPRS support node(s) (SGSN).

Server(s) 1160 in mobile network platform 1110 can execute numerous applications (e.g., location services, online gaming, wireless banking, wireless device management . . . ) that can generate multiple disparate packetized data streams or flows, and manage (e.g., schedule, queue, format . . . ) such flows. Such application(s), for example can include add-on features to standard services provided by mobile network platform 1110. Data streams (e.g., content(s) or signaling directed to a file) can be conveyed to PS gateway node(s) 1122 for authorization/authentication and initiation of a data session, and to serving node(s) 1170 for communication thereafter.

Server(s) 1160 can also effect security (e.g., implement one or more firewalls) of mobile network platform 1110 to ensure network's operation and data integrity in addition to authorization and authentication procedures that CS gateway node(s) 1112 and PS gateway node(s) 1122 can enact. Moreover, server(s) 1160 can provision services from external network(s), e.g., WAN 1130, or Global Positioning System (GPS) network(s) (not shown). It is to be noted that server(s) 1160 can include one or more processors configured to confer at least in part the functionality of macro network platform 1110. To that end, the one or more processor can execute code instructions stored in memory 1120, for example.
