## Abstract

Various methods, apparatuses and articles of manufacture are provided for use by one or more electronic devices to detect and/or respond to certain changes (anomalies) within a wireless signaling environment. For example, a first electronic device may receive a report of a threshold anomaly detected by a monitoring device deployed at a fixed predetermined position within a coverage area of a network service device, and may initiate an investigation by requesting that a second electronic device attempt to monitor certain transmissions of and/or actively communicate with a network service device. In response to a determination based, at least in part, on the investigation that the threshold anomaly represents a threshold change in status within the wireless signaling environment, the first electronic device may transmit a status report regarding the wireless signaling environment to another electronic device.

## Background
BACKGROUND
1. Field
The subject matter disclosed herein relates to electronic devices, and more particularly to methods, apparatuses and articles of manufacture for use by one or more electronic devices to detect and/or respond to certain anomalies and/or certain changes within a wireless signaling environment.
2. Information
As its name implies, a mobile station may be moved about, e.g. typically being carried by a user and/or possibly a machine. By way of some non-limiting examples, a mobile station may take the form of a cellular telephone, a smart phone, a tablet computer, a laptop computer, a wearable computer, a navigation and/or tracking device, etc.
A mobile station may allow for a wide variety of wireless communication capabilities and services. For example, a mobile station may allow a user to make telephone calls, send and receive emails, attended video teleconferences, access other devices, download and playback content, surf the Internet, etc. A plethora of different types of network access devices may be provided to support such activities. For example, various cellular base stations, femto cell and/or pico cell devices, and/or other like service area extenders/repeaters may be provided. For example, various access point devices, Wi-Fi hotspots, and/or the like may be provided to support various types of wireless area networks.
In addition to providing various communication capabilities, mobile station may also be configured to support various positioning/navigation capabilities. For example, a position and/or movements of a mobile station may be determined, at least in part, by a positioning and/or navigation capability (herein after simply referred to as a positioning capability) that may be implemented on board the mobile station, in one or more other electronic devices, and/or some combination thereof. Certain positioning capabilities may be based on one or more wireless signals transmitted by one or more transmitting devices and acquired by mobile station. By way of example, certain wireless signal-based positioning capabilities make use of wireless signals acquired from a satellite positioning system (SPS), such as, e.g., the global positioning system (GPS), etc. In another example, certain wireless signal-based positioning capabilities make use of wireless signals acquired from terrestrial-based wireless transmitting devices, such as, e.g., a dedicated positioning Beacon transmitting device, an access point (AP) which may be part of a wireless local area network, a base transceiver station which may be part of the cellular telephone system, and/or the like or some combination thereof. In certain implementations, a positioning capability may make use of one or more electronic files, such as, e.g., an electronic map, a routability graph, a radio heatmap, and/or the like or some combination thereof, to determine a position and/or other movements of the mobile station within a particular environment.
Accordingly with all of these important capabilities, it may be beneficial to monitor and understand how the various electronic devices are behaving (operating) and/or hence possibly serving one another within a wireless signaling environment. One way to monitor such electronic devices is to receive information regarding the experiences that such devices undergo. For example, a mobile device may gather information about its experience operating effectively or ineffectively with one or more other devices. Such information may be subsequently shared and analyzed, e.g., to possibly determine how well a system/network is performing. However, in certain situations, the gathering of such performance data in this manner may prove inefficient, slow, possibly prohibited, incomplete, expensive, etc.

DETAILED DESCRIPTION
Various techniques are described herein which may be implemented in one or more electronic devices to at least assist with detecting certain anomalies within a wireless signaling environment, possibly initiating an investigation and/or supporting such investigation in response to one or more anomalies being detected, and determining (e.g., based at least in part, on the investigation) whether certain changes have occurred within a wireless signaling environment. An anomaly may represent a significant change within a wireless signaling environment. In certain implementations, certain detectable changes within a wireless signaling environment may be determined to be significant, and hence represent an anomaly, based, at least in part, on one or more threshold comparisons, and/or the like. For example, various signal characteristics/parameters may be measured and compared to one or more applicable threshold ranges and/or values. For example, a presence of a different signal (e.g., possibly new), or a loss/absence of an expected signal may be detected based, at least in part on a comparison of an applicable threshold list of signals/transmitters and/or the like associated with a wireless signaling environment. In certain examples, such a threshold list may indicate specific transmitting devices (e.g., by unique identifier, SSID, etc.), and/or may indicate one or more threshold ranges or values regarding numbers of one or more types of transmitting devices (e.g., expected, allowed, minimum, maximum, per vender, etc.).
Accordingly, in certain instances, an anomaly may, for example, occur and be detected based, at least in part, on acquiring signals from one or more new or different transmitting devices (e.g., which may be part of a newly deployed network). Indeed, in certain instances, a specific anomaly detection may consider whether the transmitting devices may be identified (e.g., based on unique identifiers, SSID, etc.) as possibly corresponding to a particular vendor, service provider, and/or other like entity.
These are but a few examples of anomalies (e.g., a threshold anomalies) that may detected, and hence claimed subject matter is not necessarily intended to be so limited.
In certain example implementations, in response to a determination that certain changes in status within a wireless signaling environment have occurred, one or more status reports may be provided to one or more electronic devices which may operate in some manner based on one or more wireless signals received and/or transmitted within the wireless signaling environment. For example, a status report may be transmitted to one or more electronic devices associated with a service provider, and/or other like possibly interested entity. For example, in response to receiving a status report, an additional investigation (e.g., into a potential problem, etc.) may be initiated.
In certain instances, status report may simply indicate that an anomaly has been detected. Hence, for example, a status report may take the form of an indicator (e.g., flag, value, field, etc.), may be provided in one or more messages (e.g., in a body of the message, a header of the message, or elsewhere) to indicate an anomaly. In certain example implementations, such an indicator may be further indicative of one or more anomalies. In certain example implementations, such an indicator may be provided as part of a specific message(s), and/or possibly as part of one or more messages having other related or unrelated purposes. In certain instances, a status report may take the form of a telephone call, an electronic mail, a tweet, and/or the like, which may be received and applicably processed by a person and/or machine. In certain instances, a status report may vary in its form, transmission time(s), recipient(s), etc., depending on the type(s) of anomaly(ies) being reported.
Attention is drawn to FIG. 1, which is a schematic block diagram illustrating an arrangement 100 of representative electronic devices and an applicable wireless signaling environment 102. In certain instances, wireless signaling environment 102 may comprise all or part of one or more indoor environments, e.g., within one or more structures. Thus, by way of example, wireless signaling environment 102 may represent all or part of a building, a campus, an arena, a shopping mall, an airport, etc.
As shown, one or more network service devices (represented by access points (APs)) is may be provisioned within and/or possibly nearby wireless signaling environment 102 to provide or support certain services to one or more other electronic devices that may be present at times with wireless signaling environment 102. By way of example, AP 104-1, AP 104-2 . . . AP 104-n are illustrated in arrangement 100, with AP 104-2 being illustrated as being provisioned outside of wireless signaling environment 102. AP 104-1 may transmit and/or receive one or more wireless signals within at least a portion of wireless signaling environment 102 as represented by communication link 105-1. AP 104-1 may also communicate with one or more other electronic devices, represented here by network(s) 120 over one or more wired and/or wireless communication links represented by communication link 127. As further shown, AP 104-2 and AP 104-n may also transmit and/or receive one or more wireless signals within at least a portion of wireless signaling environment 102 as represented by communication links 105-2 and 105-n, respectively. Additionally, as shown AP 104-2 and AP 104-n may also communicate with network(s) 120 over one or more wired and/or wireless communication links represented by shared communication link 123.
In addition to providing wireless signaling supporting communication, it should also be understood that in certain example implementations one or more network service devices (represented by the APs in arrangement 100) may transmit wireless signals which may be used for location estimation and/or other like positioning/navigation and/or location based services, e.g., applicable to one or more mobile stations 114. Hence, in certain instances, a network service device may support communication with a particular communication network/system and also location estimation. However in certain other instances, some network service devices may not necessarily support communication with particular communication network/system, but instead support location estimation. Thus, for example in certain instances, one or more of the APs and arrangement 100 may represent a location Beacon transmitting device and/or the like.
While illustrated similarly, it should be understood that two or more of AP 104-1, AP 104-2, . . . AP 104-n may represent different types of network service devices. Further, it should be understood that AP 104-1, AP 104-2, . . . AP 104-n may be provisioned as part of one or more wireless communication networks/systems. Thus, in certain instances: AP 104-1 may represent an access point device and/or the like provisioned as part of a wireless local area network (WLAN) and/or the like; and, AP 104-2 may represent a base station, repeater, and/or the like provisioned as part of a cellular network and/or the like; wherein, the WLAN and/or cellular network may be capable of providing access to an intranet, the Internet, etc. As may be appreciated, such network service devices may be configured to provide and/or otherwise support various communication capabilities within wireless signaling environment 102. By way of example, one or more network service devices may be configured to provide and/or otherwise support wireless communication involving one or more mobile stations 114. By way of example, AP 104-1 may receive one or more messages from mobile station 114 and/or transmit one or more messages to mobile station 114 through communication link 105-1. By way of example, AP 104-1 may further receive one or more messages via network(s) 120 and/or transmit one or more messages via network(s) 120 through communication link 127. As illustrated, network(s) 120 may be coupled via one or more wired and/or wireless communication links 110 to one or more electronic devices, e.g., illustrated here by computing device 110. It should be recognized that in certain instances, communication may be provided and/or supported between computing device 110 and one or more of the representative electronic devices illustrated within wireless signaling environment 102. Hence, for example, mobile station 114 may communicate with computing device 110 through communication link 105-1, AP 104-1, communication link 127, network(s) 120, and communication link 111. In another example, a monitoring device 106-1 may communicate with computing device 110 through a (wireless) communication link 121, network(s) 120, and communication link 111. Although not illustrated, in certain instances, a monitoring device 106-1 may additionally and/or alternatively communicate with computing device 110 through a (wireless) communication link 107-1 via one or more of the APs. Likewise, in certain instances, monitoring device 106-1 may communicate with one or more other electronic devices through communication link 107-1.
While computing device 110 and network(s) 120 are illustrated in arrangement 100 as being provisioned outside of wireless signaling environment 102, it should be understood that in certain implementations all or part of computing device 110 and/or network(s) 120 may be provisioned within wireless signaling environment 102. Similarly, while representative monitoring devices 106-1 through 106-k are illustrated within arrangement 100 as being provisioned within wireless signaling environment 102, it should be understood that in certain implementations all or part of such monitoring devices may be provisioned outside but near wireless signaling environment 102.
As described in greater detail herein, various techniques may be implemented wherein one or more monitoring devices may be provided to detect certain anomalies, e.g., threshold anomalies, within a wireless signaling environment 102. By way of an initial example, monitoring device 106-1 may be deployed at a fixed pre-determined position within a coverage area of at least one of the network service devices within wireless signaling environment 102. Monitoring device 106-1 may, for example, comprise a communication interface capable of receiving and transmitting wireless signals, e.g., via indication links 107-1 and/or 121.
As illustrated, monitoring device 106-1 may comprise an apparatus 108 which may be configured to detect one or more threshold anomalies in one or more wireless signals corresponding to one or more of the APs 104 within wireless signaling environment 102. For example, in certain instances, apparatus 108 while operating in a passive (e.g., “listening”) mode and/or an active (e.g., transmitting) mode may detect a threshold anomaly within wireless signaling environment 102 based, at least in part, on one or more signal strength measurement values (e.g., a received signal strength indicator (RSSI), etc.) for one or more wireless signals transmitted by a network service device as received at monitoring device 106-1. In another example, in certain instances, apparatus 108 while operating in a passive mode and/or an active mode may detect a threshold anomaly within wireless signaling environment 102 based, at least in part, on one or more measured propagation times (e.g., time of flight (TOF), etc.) and/or one or more corresponding distance measurements of one or more wireless signal transmitted by a network service device. In yet another example, in certain instances, apparatus 108 while operating in an active mode may detect a threshold anomaly within wireless signaling environment 102 based, at least in part, on one or more measured propagation times (e.g., round trip time (RTT), etc.) and/or a corresponding distance measurement of one or more wireless signal transmitted between monitoring device 106-1 and a network service device.
In certain example implementations, monitoring device 106-1 may detect a threshold anomaly by comparing one or more of such measured characteristics with one or more expected signal characteristics for at least an applicable portion of wireless signaling environment 102 and/or a coverage area of a particular network service device. In certain instances, such an expected signal characteristic may be predetermined and/or otherwise provided to the monitoring device. In certain instances, such an expected signal characteristic may be indicative of one or more applicable threshold ranges and/or values, etc., from which anomalous behavior may be detected. As may be appreciated, in certain instances, an expected signal characteristic may be based on actual and/or simulated wireless signaling information. Thus, for example, in certain instances, one or more modeling functions may be applied to characterize wireless signaling environment 102 and/or a coverage area of a particular network service device with regard to the predetermined position of a particular monitoring device. In certain instances, some modeling functions may use simulated measurements corresponding to wireless signal transmission/reception. In certain instances, some modeling functions may use actual measurements corresponding actual wireless signal transmission/reception. Such modeling functions and/or other like communication characterization techniques are well known and beyond the scope of the present description. It should however, be understood that such capabilities may be provided via one or more electronic devices within arrangement 100.
As illustrated using monitoring device 106-k, in certain implementations a monitoring device may comprise an antenna 130 that may be configurable in some manner. By way of example, in certain implementations, antenna 130 may be adaptable, steerable and/or otherwise configurable in some manner to selectively affect transmission and/or reception of one or more wireless signals. Hence, in certain instances a monitoring device may be responsive to one or more recommended transmitters settings and/or one or more recommended receiver settings. For example, as described in greater detail herein, in certain implementations a status report may be received by monitoring device from computing device 110 which is indicative of one or more one or more recommended transmitter and/or receiver settings, which may been determined as a result of investigating a previously reported threshold anomaly. Accordingly, a monitoring device may be updated by computing device 110 from time to time based on certain investigations corresponding to reported threshold anomalies and/or possibly threshold changes in the status of wireless signaling environment 102. Indeed, in certain instances, a status report from computing device 110 may be indicative of one or more updated expected signal characteristics and/or certain criterion that may be used by monitoring device, e.g., and in detecting subsequent threshold anomalies within wireless signaling environment 102.
Network(s) 120 is intended to represent all or part of one or more other electronic devices and/or communication facilities and/or resources capable of supporting wired and/or wireless electronic communication. Thus for example, network(s) 120 may comprise all or part of a telephone network, a cellular telephone network, a wireless communication network, an intranet, the Internet, and/or the like or some combination thereof.
Attention is drawn next to FIG. 2A, which is a flow diagram illustrating example process 200 that may be implemented in computing device 110 and/or apparatus 112 (FIG. 1) to investigate and determine whether a threshold change in a status has occurred within a wireless signaling environment.
At example block 202, one or more reports indicative of one or more threshold anomalies having been detected by one or more monitoring devices within a wireless signaling environment may be received, e.g., by computing device 110. In accordance with certain example implementations, a monitoring device may be deployed at a fixed predetermined position, e.g., within a coverage area (e.g., expected and/or actual) of at least one network service device. Accordingly, in certain instances, a report of a threshold anomaly may be indicative of a particular network service device and/or a particular wireless signal corresponding to such network service device. Thus, for example, a report from a monitoring device may identify a unique identifier and/or the like of a network service device, and/or a unique identifier and/or the like of a wireless signal indicative of a particular network service device.
As mentioned in previous examples, a monitoring device may detect a threshold anomaly based on some characteristic of a wireless signal which may be compared to an expected characteristic, etc. Thus, by way of example, a monitoring device may detect a threshold anomaly based, at least in part, on loss/absence of a particular wireless signal, and/or some other measurable characteristic which may exceed a threshold value/range, threshold model/function, some other threshold-based criterion, and/or the like or some combination thereof. For example, in certain instances, a threshold value/range corresponding to a signal power change may indicate that an anomaly is present when a signal power changes by more than a certain particular unit-based value (e.g., RSSI, dBm, mw, nw, etc.) more than a percentage (e.g., 20%, 50%, etc.) of an expected, nominal, and/or reference level. For example, in certain instances, a threshold value/range corresponding to a number of transmitting devices may apply to one or more types of transmitting devices (e.g., by operation, vendor, service provider, etc.) and/or a number or range of such transmitting devices (e.g., expected, maximum, minimum, etc.).
Those skilled in the art should recognize that a plethora of signal characteristic-based tests and/or comparisons may be applied to assist in detecting a threshold anomaly. Further, it should be understood that, while in certain threshold anomaly detections may be instantly recognizable (e.g., a loss or substantial degradation in a wireless signal), and other instances, a threshold anomaly detection process may extend over a period of time, and may include the application of certain statistical and/or other like techniques.
At example block 204, an investigation of at least one of the threshold anomalies and/or said network service devices (e.g., as reported at block 202) may be initiated, e.g., by computing device 110. Here, for example, computing device 110 may transmit one or more messages to one or more other electronic devices (e.g., at least a “second electronic device”) requesting that the one or more other electronic devices attempt to monitor transmissions from a network service device and/or actively communicate with such network service device. By way of example, in certain instances, such a “second electronic device” may comprise a monitoring device reporting the threshold anomaly, and/or one or more other monitoring devices. Thus, for example, if a first monitoring device reports a threshold anomaly with regard to a particular network service device, it may be beneficial for computing device 110 as part of an investigation to request (assign) that a second monitoring device attempt to passively and/or actively monitor the particular network service device and/or a wireless signal associated there with. For example, with reference back to FIG. 1, let us assume that a first monitoring device 106-1 reports a threshold anomaly corresponding to AP 104-1 to computing device 110. Computing device 110 may transmit a message to monitoring device 106-k requesting that monitoring device 106-k attempt to monitor transmissions from AP 104-1. To support the investigation initiated by computing device 110, monitoring device 106-k may subsequently passively listen for wireless signals from AP 104-1 over communication link 105-1, and/or possibly actively transmit wireless signals to from AP 104-1 over communication link 105-1. As part of such an investigation, monitoring device 106-K may transmit feedback regarding its attempt(s) to monitor the transmissions and/or communicate with AP 104-1.
In certain instances, feedback may simply indicate a confirmation or lack thereof of a particular threshold anomaly. Hence, for example, certain feedback may take the form of an indicator (e.g., flag, value, field, etc.), may be provided in one or more messages (e.g., in a body of the message, a header of the message, or elsewhere) to indicate confirmation or lack thereof. In certain example implementations, such an indicator may be further indicative of additional data/information corresponding to the confirmation, and/or possibly one or more other threshold anomalies. In certain example implementations, such an indicator may be provided as part of a specific message(s), and/or possibly as part of one or more messages having other related or unrelated purposes.
Consequently, with feedback from one or more other electronic devices, computing device 110 may determine whether a reported threshold anomaly may or may not represent and/or otherwise correspond to a threshold change in status within the wireless signal environment. In making such a decision, computing device 110 may, for example, apply a true/false threshold-based analysis based on feedback obtained, and/or may apply other more complex types of analyses.
At example block 206, in response to a determination based, at least in part, on the investigation that a reported threshold anomaly represents a threshold change in status within the wireless signaling environment, a status report regarding the wireless signaling environment may be transmitted to at least one electronic device. Thus, for example, one or more status reports may be transmitted to one more network service devices, one or more monitoring device, one or more mobile stations, and/or one or more computing devices. In certain instances, an example status report may be indicative of an expected signal characteristic (e.g., being updated, revised, temporary affected, newly identified, etc.) within at least a portion of the wireless signaling environment. By way of example, a status report may be indicative of a new or changed wireless signal parameter, model, function, heatmap (e.g., RSSI, RTT, etc.), and/or the like. Indeed, in certain instances an example status report may comprise of positioning assistance data, e.g., for use by a mobile station to facilitate and/or enable location determination services.
In certain example implementations, a status report may be indicative of a recommended transmitter setting for use within at least a portion of the wireless signaling environment. Hence, a recommended transmitter setting may provide certain hints that may be of use to certain electronic devices which may attempt to transmit wireless signals to a particular network service device. By way of some non-limiting examples, a recommended transmitter setting may be indicative of a recommended transmit power level setting, a recommended channel setting, a recommended frequency band, a recommended transmission time, a recommended protocol setting, a recommended antenna setting, and/or the like or some combination thereof.
In certain example implementations, a status report may be indicative of a recommended receiver setting for use within at least a portion of the wireless signaling environment. Hence, a recommended receiver setting may provide certain hints that may be of use to certain electronic devices which may attempt to receive wireless signals from a particular network service device. By way of some non-limiting examples, a recommended receiver setting may be indicative of a recommended receiver gain setting, a recommended channel setting, a recommended frequency band, a recommended reception time, a recommended protocol setting, a recommended antenna setting, and/or the like or some combination thereof.
In certain example implementations, a status report resulting from an investigation may be indicative of a criterion and/or the like, e.g., which may be applied by a monitoring device in detecting a subsequent threshold anomaly within the wireless signaling environment. Thus, for example, a status report may provide a capability to adjust or otherwise affect certain threshold-based factors that may be applied in detecting threshold anomalies. As such, status reports may assist in tuning monitoring devices when applicable.
For at least these reasons and others, as may be appreciated, in certain instances, a status report may be indicative of very specific information, e.g., intended for a particular recipient device, service, process, function, etc. However, in other instances, a status report may serve a plurality of different purposes and/or recipient devices, etc.
In certain further instances, a status report may be provided to one or more electronic devices capable of alerting one or more service providers, entities, machines, persons, etc., e.g., regarding the presence or absence of a particular threshold anomaly, threshold change in status within a wireless signaling environment, a potential problem with one or more electronic devices, a potential correction of a problem with one or more electronic devices, etc.
Attention is drawn next to FIG. 2B, which is a similar flow diagram illustrating example process 200′ that may be implemented in computing device 110 and/or apparatus 112 (FIG. 1) to investigate and determine whether a threshold change in a status has occurred within a wireless signaling environment.
Example process 200′ comprises example blocks 202, 204, and 206, e.g., as described above in process 200 (FIG. 2A), with some additional example modifications/enhancements.
More specifically, example block 204 illustrates through example block 212 that, as part of an investigation, feedback may be received from a second electronic device regarding an attempt to monitor transmissions from a network service device and/or to actively communicate with such network service device. As mentioned, example block 212 may in certain implementations allow computing device 110 and/or apparatus 112 to obtain additional information regarding a particular network service device and/or wireless signaling environment 102, which may inform its determination as to whether or not a threshold change in status within the wireless signaling environment as occurred, and/or provide additional support in preparing certain status reports (e.g., at block 206).
Process 200′ also includes an example block 210, which illustrates that a second report indicative of a second threshold anomaly within a wireless signaling environment may be received, e.g., from a second monitoring device deployed at a second fixed predetermined position. Accordingly, in certain implementations, as may be appreciated, at block 204, an investigation of at least one of the reported threshold anomalies and/or one of the applicable network service devices may be initiated based on a plurality of reports. Thus, for example, while in certain instances it may be desirable to initiate an investigation based on a single report of a threshold anomaly detection, and certain other instances it may be desirable to initiate an investigation in response to two or more reported threshold anomaly detections. Indeed, in certain instances certain threshold anomaly detections reported by certain monitoring devices may be considered to be more or less accurate than others, and therefore their respective influence/weight may vary.
Attention is drawn next to FIG. 3A, which is a flow diagram illustrating example process 300 that may be implemented in monitoring device 106-1 and/or apparatus 108 (FIG. 1) to detect and report one or more threshold anomalies within wireless signaling environment 102, and possibly to assist in an investigation of a threshold anomaly, e.g., in support of a determine as to whether a threshold change in a status may or may not have occurred within a wireless signaling environment.
At example block 302, a threshold anomaly may be detected within a wireless signaling environment at the fixed predetermined position of a monitoring device based, at least in part, on passively monitoring wireless signal transmissions within the wireless signaling environment. Several examples of such activities have been previously described.
At example block 304, a report indicative of a threshold anomaly may be transmitted to at least one electronic device. By way of example, with reference to FIG. 1, monitoring device 106-1 and/or apparatus 108 provisioned therein may transmit at least one report to computing device 110 and/or arrangement 112 provisioned therein.
At example block 306, an attempt may be made to actively communicate with the network service device corresponding to the detected threshold anomaly. By way of example, monitoring device 106-1 having detected a threshold anomaly while monitoring wireless signals transmitted by AP 104-1 over communication link 105-1, may transmit one or more wireless signals over communication link 107-1 in an attempt to probe or otherwise attempt to establish communication with AP 104-1. In certain example implementations, an attempt to communicate in accordance with example block 306 may be initiated independently by monitoring device 106-1 and/or apparatus 108. In certain example implementations, an attempt to communicate in accordance with example block 306 may be initiated in response to receiving one or more messages requesting such as part of an investigation, e.g., from computing device 110 (see also, example block 204 in process 200 of FIG. 2A).
At example block 308, feedback indicative of a result of the attempt to actively communicate with the network service device (e.g., as per example block 306), may be prepared for possible transmission to another electronic device. Thus, for example, in certain instances, feedback prepared at block 308 may be stored in memory. In certain instances, such feedback may be beneficial to the monitoring device and future attempts to indicate with the network service device and/or in detecting a future threshold anomaly. Indeed, in certain instances, feedback prepared at block 308 may indicate that the threshold anomaly detected at block 302 and reported that block 304, may or may no longer be considered valid by the monitoring device.
Attention is drawn next to FIG. 3B, which is a similar flow diagram illustrating example process 300′ that may be implemented in monitoring device 106-1 and/or apparatus 108 (FIG. 1) to detect and report one or more threshold anomalies within wireless signaling environment 102, and possibly to assist in an investigation of a threshold anomaly, e.g., in support of a determine as to whether a threshold change in a status may or may not have occurred within a wireless signaling environment.
Example process 300′ comprises example blocks 302, 304, 306, and 308, e.g., as described above in process 300 (FIG. 3A), with some additional example modifications/enhancements.
At example block 310, all or part of the feedback prepared at block 308, may be transmitted to at least one other electronic device, e.g., in response to having received a message from the at least one electronic device requesting that the monitoring device attempt to actively communicate with one or more particular network service devices. Thus, for example, at example block 310, monitoring device 106-1 and/or apparatus 108 may provide further support for an investigation initiated by computing device 110 and/or apparatus 112 by providing such feedback.
At example block 312, a status report may be received from at least one electronic device regarding the wireless signaling environment. As previously mentioned, such a status report may be based, at least in part, on an investigation initiated in response to a threshold anomaly, e.g., as detected at example block 302 and reported at example block 304).
In certain example implementations, an indoor area may be populated with multiple (potentially low cost) monitoring devices, e.g., which may be fixed predetermined positions for obtaining signal measurements for use in monitoring a wireless signaling environment based on certain expected signaling characteristics (e.g., which may be based at least in part on an RSSI and/or RTT heatmap, and/or the like). At the time of deployment, such monitoring devices may be installed or strategically placed at known positions based, at least in part, on particular conditions, geometries, just to provide a couple of examples.
As previously described in the various preceding examples, a monitoring device may perform periodic passive scans and active measurements. If a threshold anomaly is detected by a monitoring device, the monitoring device may report such to one or more other electronic devices. Such a monitoring device may also, in certain instances, participate and a follow-up investigation process should one be initiated.
In a particular example implementation, a plurality of monitoring devices may be deployed in an area to monitor or “listen” to transmissions of a maximum number of APs. Monitoring device placement may be based on a number APs it can hear (e.g., placed to hear certain minimum number of surrounding APs). Monitoring devices may be placed at particular locations where there may be a line of sight (LOS) channel to a maximum number of APs. In certain instances, one or more monitoring devices may be placed close to certain (possibly relatively more important) APs, e.g., APs more likely to be relied upon for indoor positioning operations, or possibly other exigent services.
Monitoring device placement may be based on a simulated heatmap of the environment, e.g. using a greedy algorithm and/or the like. Here, in a particular example implementation, a first monitoring device may be placed at a first grid point where it is likely to hear transmissions from a maximum number of APs. A second monitoring device may be placed at a second grid point that can hear the next maximum number of APs disjoint from APs that are likely to be heard by the first monitoring device placed at the first grid point. A Monitoring device may also be placed at the more important geographic location, locations with high mobile station and/or other device traffic (e.g., an entrance/exit of a building, an elevator entrance, a stairwell door, an escalator, etc.).
In another implementation, multiple new APs detected by a monitoring device may indicate deployment of a new network and the detecting monitoring device may report a threshold anomaly to at least one other electronic device. If newly detected APs are from the same vendor or have same SSID, such a threshold anomaly detection report may be transmitted with an indication of a higher confidence of deployment of a new network.
In another implementation, a significant decrease in a number of detectable APs at a point of monitoring device deployment may indicate that an existing network has changed. Also, significant changes in an AP's transmission power may indicate that such an existing network has changed. If a power adaptive AP system is deployed, changes in AP transmission power may be indicated or otherwise reported to at least one other electronic device, e.g., possibly at certain time intervals.
