The present disclosure is generally related to analyzing a wireless information delivery system.
A wireless local area network may provide wireless access to a network at multiple locations within a coverage area (e.g., a particular geographic area). Wireless local area networks enable network-connected devices to be moved within the coverage area. However, signal strength of the wireless local area network may be better at some locations than at other locations within the coverage area. If a problem develops related to network access via wireless connection, it can be difficult to determine whether the problem is related to communications in the network or is related to problems with the wireless connection.
A wireless information delivery system may enable network access at a particular location (e.g., a subscriber premises). The wireless information delivery system may include a residential gateway that communicates with a provider via, e.g., a wired communication medium, such as a coaxial cable or a twisted wire pair, an optical fiber, or a combination thereof. A communication path between the residential gateway and the provider may also include one or more wireless connections, such as a satellite transmission, a wireless data transmission (e.g., WiFi, WiMAX), another data transmission, or any combination thereof. The residential gateway may provide wireless access to the network for one or more devices, such as a set-top box, via, e.g., a local transmitter that may reside within or be coupled to the residential gateway.
An installation technician may be sent to install customer premises equipment at the subscriber premises. The customer premises equipment may be intended to provide network access within a predetermined space. The customer premises equipment may include the residential gateway and one or more set-top boxes. As part of an install procedure the technician may create an initial parameter map associated with the subscriber premises. The initial parameter map may include measurements of various system parameters associated with information reception via a wireless local area network including the customer premises equipment. The measured parameters may be related to wireless signal strength, packet stream data, or a combination thereof, and may be measured at several geographic positions within a predetermined space (e.g., the subscriber premises) using a system analysis tool that may have a capability to measure and analyze parameters associated with signal transmission and packet transmission. The installation technician may upload the initial parameter map to a central repository that stores subscriber information associated with each subscriber to a communication service offered by the provider.
When a communication service problem, such as a dropped connection, an intermittent connection, or another problem, is experienced by the subscriber, the provider may be contacted by the subscriber with a request to remedy the problem. The provider may send a repair technician to the subscriber premises in order to troubleshoot and remedy the problem. Use of the system analysis tool having the capability to measure and analyze parameters associated with signal transmission and packet transmission may enable the repair technician to efficiently identify the problem and to implement a solution.
For example, the repair technician may create a current parameter map using the system analysis tool. The repair technician may download the initial parameter map for comparison to the current parameter map. The comparison of the two maps may enable the repair technician to quickly recognize a source of the reported problem. For example, rearrangement of furniture by the subscriber may result in a difference in certain measured parameter values (e.g., signal strength) at various locations and may be detected through comparison of the two maps. Discovering one or more difference by comparison of the initial parameter map to the current parameter map may shorten time to troubleshoot the residential system.
In a particular embodiment, a method includes receiving a packet stream via a wireless signal from a device, e.g., a wireless gateway, of a wireless information delivery system. The method includes determining wireless signal data associated with the wireless signal during a particular time interval, determining packet stream data associated with the packet stream received during the particular time interval, and analyzing the wireless signal data and the packet stream data to produce an assessment of at least a portion of the wireless information delivery system.
In a particular embodiment, an apparatus includes a system analysis tool including a processor configured to determine wireless signal data associated with a wireless signal received from a wireless information delivery system during a particular time interval. The processor is configured to determine packet stream data associated with a packet stream received during the particular time interval via the wireless signal. The processor is configured to analyze the wireless signal data and the packet stream data to produce an assessment of at least a portion of the wireless information delivery system. For example, the assessment may include an indication of one or more anomalies in the wireless signal data and the packet stream data that may be associated with one or more root causes of a reported problem associated with the wireless information delivery system.
In a particular embodiment, a computer-readable medium stores processor-executable instructions that, when executed by a processor, cause the processor to receive a packet stream via a wireless signal from a device of a wireless information delivery system. The computer-readable medium stores processor-executable instructions that, when executed by the processor, cause the processor to determine wireless signal data associated with the wireless signal during a particular time interval, to determine packet stream data associated with the packet stream received during the particular time interval, and to analyze the wireless signal data and the packet stream data to produce an assessment of at least a portion of the wireless information delivery system.
The server 102 may include a processor 114 coupled to an interface 116. The interface 116 may be coupled to the network 118. The server 102 may also include or be coupled to a content database 109. The content database 109 may provide content, such as video content, to the processor 114. The processor 114 may provide the content to the network 118 via the interface 116. Content may also be retrieved by the server 102, e.g., from an external source (not shown) via the network 118, and the retrieved content may be provided to one or more recipients via the network 118. The server 102 also may include, or be coupled to, an operations systems server/billing systems server (OSS/BSS) database 112. The OSS/BSS database 112 may store subscriber-related data. For example, the OSS/BSS database 112 may store analysis results obtained by the system analysis tool 101. The stored results may be retrieved at a future time (e.g. in response to a reported problem) as reference data that may be used for troubleshooting purposes.
The system analysis tool 101 may include a transceiver 106, a packet stream generator 108, a wireless signal data calculator 114, a packet data calculator 116, and an analyzer 132. The packet stream generator 108 may be configured to generate one or more packet streams, such as a packet stream 110. The packet stream 110 may be transmitted to the residential gateway 120 wirelessly via the transceiver 106. The residential gateway 120 may transmit a wireless signal 124 that includes the packet stream 110 that the residential gateway 120 received from the system analysis tool 101.
The system analysis tool 101 can monitor wireless signals, such as the wireless signal 124 sent by the residential gateway 120 to the set-top box 104. For example, the transceiver 106 may receive the wireless signal 124 broadcast from the residential gateway 120. The transceiver 106 may provide wireless data 126 to the wireless signal data calculator 114 and to the packet data calculator 116. In response to the wireless data 126, the wireless signal data calculator 114 may output wireless signal data 128. In response to the wireless data 126, the packet data calculator 116 may output packet stream data 130. The wireless signal data 118 and the packet stream data 130 may be input to the analyzer 132.
In operation, the server 102 may send content, such as video content, audio content, a mixture of video content and audio content, or other content to the set-top box device 104. The content may be transmitted via the network 118 to the residential gateway 120. The residential gateway 120 may communicate the content via the wireless signal 124. For example, the residential gateway 120 may send the wireless signal 124 to the set-top box device 104. The set-top box device 104 may receive the wireless signal 124 and may send data recovered from the wireless signal 124 to, e.g., a television receiver (not shown). The wireless signal 124 may also be received by the system analysis tool 101.
A repair technician may employ the system analysis tool 101 to troubleshoot a residential system that includes the residential gateway 120 and one or more set-top boxes, including the set-top box device 104. The system analysis tool 101 may send the packet stream 110 to the residential gateway 120 via the transceiver 106. Alternatively, the packet stream 110 may be generated by the processor 114 of the server 102 and may be sent to the residential gateway 120, e.g., via the network 118. The residential gateway 120 may retransmit the packet stream 110 in one or more wireless signals, such as the wireless signal 124.
The wireless signal 124 may be received by the transceiver 106 of the system analysis tool 101. The transceiver 106 may output the wireless data 126 based on the wireless signal 124. The wireless data 126 may be input to the wireless signal data calculator 114, where one or more signal parameters may be calculated. The wireless data 126 may also be supplied to the packet data calculator 116, where one or more packet parameters may be calculated. The wireless signal parameters calculated by the wireless signal data calculator 114 may be provided to the analyzer 132 as wireless signal data 128. The packet parameters calculated by the packet data calculator 116 may be provided to the analyzer 132 as packet stream data 130. The analyzer 132 may analyze the wireless signal data 128 and the packet stream data 130 and may provide an analysis of the system 100 based upon the wireless signal parameters and the packet data parameters. The analysis may be stored locally in a memory 134, may be stored remotely, e.g. in the OSS/BSS database 112, or both. In a particular embodiment, the wireless signal data 128 and the packet stream data 130 may be analyzed (e.g., correlated) to identify a specific problem. In another particular embodiment, the system analysis tool 101 may be used to map the wireless signal data 128 and the packet stream data 130 at several locations within a particular space, such as at multiple locations within a residence, in order to identify a cause of a problem, such as a content reception problem, being experienced by a subscriber in the particular space. In a particular embodiment, the repair technician may create a current parameter map by mapping the wireless signal data 128 and the packet stream data 130. The repair technician may troubleshoot a reported problem in the residential system by comparing the current parameter map to the initial parameter map that may be, e.g., downloaded from the OSS/BSS database 112. Through a comparison of the current parameter map with the initial parameter map, the repair technician may discover one or more anomalies that may help the repair technician to conduct an efficient analysis and identify a source of the reported problem.
In a particular embodiment, the packet stream 110 may include predefined data (e.g., test data) that may be reflected in the wireless data 126 and that may be analyzed at the system analysis tool 101. For example, by analyzing changes in the packet stream 110 that occur as a result of wireless transmission from the residential gateway 120 to the transceiver 106 at various geographic locations within a predefined geographic area, such as a residence or an office, the analyzer 132 may determine that a cause of a problem is positioning of the residential gateway 120, data delivery difficulties resulting from a malfunction at the server 102 or at the network 118, another cause of the problem, or a combination thereof.
In operation, the system analysis tool 201 may generate test data 209 in the packet stream generator 208. The system analysis tool 201 may output the test data 209 to the residential gateway 220 via wireless transmission as test data 210. The residential gateway 220 may send a wireless signal 221 that includes data based on received test data 210 to the system analysis tool 201. In the system analysis tool 201, the transceiver 206 may output wireless data 226 including a packet stream based on the test data 210 (e.g., the packet stream may include the test data 210). The wireless data 226 may be input to the wireless signal data calculator 214 and may be input to the packet stream data calculator 216.
The wireless signal data calculator 214 may output the wireless signal data 228 based upon the wireless data 226. Measurements may be made at various geographic locations within a particular space (e.g., a predefined space) by moving the signal analysis tool 201 to each geographic location and measuring parameters associated with the wireless data 226, such as a wireless signal parameter, a packet stream parameter, or both. For example, the wireless signal data calculator 214 may be used to detect a first value of a wireless signal parameter based on the wireless data 226 measured at a first geographic location within the particular space during a particular time interval, and the wireless signal data calculator 214 may be used to detect a second value of the wireless signal parameter based on the wireless data 228 measured at a second geographic location within the particular space during a corresponding time interval. The wireless signal data 228 may include one or more wireless signal parameters, such as a wireless signal strength, a wireless received signal strength indicator (RSSI), a basic service set identifier (BSSID), a service set identifier (SSID), supported data rates, a center frequency, a bandwidth, beacon frame parameters, an integrated encryption scheme (IES), encryption or authentication information, a count of antennas, spatial stream capabilities, a modulation that may include one or more of direct-sequence spread spectrum (DSSS), frequency hopping spread spectrum (FHSS), orthogonal frequency-division multiplexing (OFDM), packet loss rate, signal-to-noise ratio, receive noise level indication, other signal parameters, or any combination thereof.
The packet stream data calculator 216 may provide packet stream data 230 that may be based on the wireless data 226. For example, the packet stream data calculator 216 may determine a parameter value (e.g., a count of packets that arrived in total) associated with the wireless data 226 at several geographic locations within a particular space, such as a subscriber premises, measured at times within a testing time period, e.g., while the repair technician is at the subscriber premises. The packet stream data 230 may include one or more packet stream parameter values. For example, the packet stream data calculator 216 may detect a first value of a packet stream parameter associated with the wireless data 226 at the first geographic location within the particular space (e.g., the subscriber premises) during a particular time period and the packet stream data calculator 216 may detect a second value of the packet stream parameter at the second geographic location within the particular space during the particular time period. The packet stream data 230 may be determined based on the first value of the packet stream parameter and the second value of the packet stream parameter. The packet stream data 230 may include one or more packet stream parameters, such as a number of “holes” (large gaps in a packet stream), a number of packets that arrived too late to be used, a number of packets that arrived in total, a number of audio digital rights management/cryptographic errors, a number of video digital rights management/cryptographic errors, a multicast join delay, packet retransmission statistics that may include packet retransmission rate, packet error rate, packet transmission speed, packet collisions, packet latency, ping time, forward error correction (FEC) statistics, such as internet protocol television forward error correction statistics, error concealment/macro-blocking statistics, other packet stream parameters, packet arrival time jitter, out-of-order packet arrivals, packet retransmission delay, packet retransmissions not successful within a particular time interval (e.g., the time interval begins at a time that retransmission was requested and lasts for a particular time period), or any combination thereof.
The wireless signal data 228 and the packet stream data 230 may be input to the analyzer 232. The analyzer 232 may analyze each of the wireless signal parameter values input from the wireless signal data calculator 214 and each of the packet stream parameter values that have been input from the packet stream data calculator 216. In a particular embodiment, the analyzer 232 may analyze the wireless signal parameter values and the packet stream parameter values to determine a wireless signal acceptability. In one example, the wireless signal acceptability may be determined by comparing a particular wireless signal parameter to a corresponding wireless signal threshold 240. A packet stream acceptability may be determined by comparing a particular packet stream parameter to a corresponding packet stream threshold 238. A degree of correlation between the wireless signal acceptability and the packet stream acceptability is determined via a comparator/correlator module 236. For example, the comparator/correlator module 236 may be used to compare a first wireless signal strength parameter value to the wireless signal threshold 240, yielding a first wireless signal strength parameter value comparison. For example, the comparison may indicate that the wireless signal strength is below the wireless signal threshold 240. Additionally, each of one or more packet stream parameter values may be compared to respective packet stream threshold values by the comparator/correlator module 236. For example, a first packet stream parameter value may be compared with the packet stream threshold 238 by the comparator/correlator module 236.
A correlation of wireless signal parameters and packet stream parameters may be carried out by the comparator/correlator module 236. For example, variations in RSSI (received signal strength indicator) of the WiFi signal over time at a particular position within the subscriber premises may be correlated to one or more of variations in packet error rate, packet retransmission rate, and one or more internet protocol television statistics. An outcome of the correlation may indicate that transmission errors are attributable to signal level fluctuation and may prompt a service technician to reposition some of the installed equipment in the subscriber premises. In another example, several wireless signal parameters may be correlated at a plurality of locations within the subscriber premises. A large variation within a short distance between locations may be indicative of weak or inconsistent signal reception. In yet another example, by correlating locations within the subscriber premises where the RSSI is acceptable (i.e., satisfies a signal strength threshold) and the packet error/loss in a packet stream is acceptable (e.g., packet error/loss is less than a packet error/loss threshold), a service technician can determine those locations to be acceptable locations for reception, e.g., suitable locations at which to locate wireless reception equipment.
The analyzer 232 may output an analysis that includes an assessment 248 of the wireless information delivery system 200 based upon the correlation. The assessment 248 of the wireless information delivery system may be presented to a user, such as a technician, as an assessment presentation 250.
The system analysis tool 201 may be configured to store a data record based on testing during a particular time interval (e.g., the time period during which the repair technician records signal and packet measurements). The data record may include, e.g., a mapping of the wireless signal data 228 and the packet stream data 230 at one or more locations within a particular geographical area, an identifier of a subscriber, an identifier of the particular time interval, location data associated with the particular space, other information, or any combination thereof. For example, a wireless signal data/packet stream data storage module 246 of the system analysis tool 201 may cause the wireless signal data 228 and the packet stream data 230 to be stored as the data record. In a particular embodiment, the system analysis tool 201 may store the data record at, e.g., an internal subscriber information database 254 in the memory 252. Alternatively, the system analysis tool 201 may store the data record remotely by transmitting the data record to an external database, such as the OSS/BSS database 112 of
In a particular embodiment, the repair technician may create a current parameter map by mapping the wireless signal data 228 and the packet stream data 230 at various points within a predetermined space (e.g., a subscriber premises boundary that surrounds the residential gateway 220). The repair technician may troubleshoot a reported problem in the residential system by downloading an initial parameter map generated at time of installation and stored, e.g., at the OSS/BSS database 112. Comparison of data in the current parameter map to the initial parameter map may help the repair technician to identify a source of the reported problem.
In a particular embodiment, the processor 318 may execute instructions stored in the memory 320 to analyze the wireless content delivery system. For example, the processor 318 may be configured to execute instructions to determine wireless signal data associated with a wireless signal received from a wireless information delivery system during a particular time interval. The processor 318 may also be configured to execute instructions to determine packet stream data associated with a packet stream received during the particular time interval via the wireless signal. The processor 318 may further be configured to execute instructions to analyze the wireless signal data and the packet stream data, to produce an assessment of at least a portion of the wireless information delivery system.
The memory 320 may include a plurality of sets of instructions, each of which may be executable by the processor 318. The processor 318 may execute packet stream generation instructions 322 to generate predefined test data to be included in a packet stream. The packet stream may be provided to a residential gateway, such as the residential gateway 220 of
The processor 318 may execute signal parameter detection instructions 326 to detect one or more wireless signal parameter values associated with a wireless signal received during a particular time interval, the wireless signal carrying the packet stream. The processor 318 may execute the signal parameter analysis instructions 326 to analyze the wireless signal parameter values that have been detected and to produce wireless signal data.
The processor 318 may execute the packet stream parameter detection instructions 328 to detect one or more packet stream parameter values associated with the packet stream that may have been received via the wireless signal. The processor 318 may execute the packet stream parameter analysis instructions to analyze the packet stream parameter values that have been detected to produce packet stream data.
The processor 318 may execute the signal/packet stream correlation instructions 334 to analyze the wireless signal data and the packet stream data, producing an assessment of at least a portion of the wireless information delivery system. Analyzing the wireless signal data and the packet stream data may include correlating the wireless signal data and the packet stream data to produce wireless signal/packet stream correlation results. The processor 318 may execute the wireless signal/packet stream correlation results presentation instructions 336 to provide the wireless signal/packet stream correlation results in a presentation that may be accessible by a user, such as a repair technician. The processor 318 may execute determination instructions 338 to determine a suspected cause of a particular behavior of the wireless information delivery system, e.g., based upon the wireless signal/packet stream correlation results.
In a particular embodiment, the repair technician may create a current parameter map by mapping wireless signal data measured by the system analysis tool 300, such as the wireless signal data 128, and the packet stream data measured by the system analysis tool 300, such as the packet stream data 130. The repair technician may troubleshoot a reported problem in the residential system by downloading an initial parameter map stored, e.g., at the OSS/BSS database 112. By comparing the current parameter map to the initial parameter map, the repair technician may be able to efficiently identify a source of the reported problem. The comparison may be carried out automatically, by e.g., the system analysis tool 300. For example, the signal/packet stream correlation instructions 334 may include instructions to compare the current parameter map and the initial parameter map and to identify one or more anomalies in corresponding parameter values.
The processor 318 may execute the instructions in the local data storage module 340 to store the wireless signal data, the packet stream data, and/or the wireless signal/packet stream correlation results in the local database 344. The processor 318 may execute the OSS/BSS communication module 342 to transmit the wireless signal data, the packet stream data, and/or the wireless signal/packet stream correlation results to a remote database, such as the OSS/BSS database 112 of

In one embodiment, a computer program, such as a STB computer program 438, can be embedded within the STB memory device 436.
The CPE 418, the STB 422, a remote control 430, and a TV monitor 426 may be situated in a particular geographical space 403, such as a residence or other premises associated with a subscriber. A system analysis tool 401 may be used in the particular geographical space 403 to assess the IPTV system 400 and service provided by the IPTV system 400 within the particular geographical space 403. The system analysis tool 401 may be configured to receive data from and transmit data to the CPE 418 wirelessly.
In an illustrative embodiment, the client-facing tier 402 can include a client-facing tier (CFT) switch 442 that manages communication between the client-facing tier 402 and the access network 416 and between the client-facing tier 402 and the private network 410. As illustrated in
In an illustrative embodiment, the client-facing tier 402 can communicate with a large number of set-top boxes, such as the representative set-top boxes 422, 424, over a wide geographic area, such as a regional area, a metropolitan area, a viewing area, a designated market area or any other suitable geographic area, market area, subscriber, or subscriber group that can be supported by networking the client-facing tier 402 to numerous set-top box devices. In a particular embodiment, the CFT switch 442, or any portion thereof, can include a multicast router or switch that feeds one or more video streams from a video server to multiple set-top box devices.
As illustrated in
The second APP switch 454 can be coupled to a domain controller 462 that provides Internet access, for example, to users at their computers 464 via the public network 412. For example, the domain controller 462 can provide remote Internet access to IPTV account information, e-mail, personalized Internet services, or other online services via the public network 412. In addition, the second APP switch 454 can be coupled to a subscriber and system store 466 that includes account information, such as account information that is associated with users who access the IPTV system 400 via the private network 410 or the public network 412. In an illustrative embodiment, the subscriber and system store 466 can store subscriber or subscriber data and create subscriber or subscriber profiles that are associated with IP addresses of corresponding set-top box devices 422, 424. The subscriber and system store 466 may receive measurement data 467 for storage at the subscriber and system store 466. For example, the measurement data 467 may include signal strength data and/or packet stream data mapped from one or more locations within the particular geographical space 403 and received from the system analysis tool 401.
In a particular embodiment, the application tier 404 can include a client gateway 414 that communicates data directly to the client-facing tier 402. In this embodiment, the client gateway 414 can be coupled directly to the CFT switch 442. The client gateway 414 can provide user access to the private network 410 and the tiers coupled thereto. In an illustrative embodiment, the set-top box devices 422, 424 can access the IPTV system 400 via the access network 416, using information received from the client gateway 414. User devices can access the client gateway 414 via the access network 416, and the client gateway 414 can allow such devices to access the private network 410 once the devices are authenticated or verified. Similarly, the client gateway 414 can prevent unauthorized devices, such as hacker computers or stolen set-top box devices, from accessing the private network 410, by denying access to these devices beyond the access network 416.
For example, when the first representative set-top box device 422 accesses the client-facing tier 402 via the access network 416, the client gateway 414 can verify subscriber information by communicating with the subscriber and system store 466 via the private network 410. Further, the client gateway 414 can verify billing information and status by communicating with the OSS/BSS gateway 458 via the private network 410. In one embodiment, the OSS/BSS gateway 458 can transmit a query via the public network 412 to the OSS/BSS server 460. After the client gateway 414 confirms subscriber and/or billing information, the client gateway 414 can allow the set-top box device 422 to access IPTV content and VOD content at the client-facing tier 402. If the client gateway 414 cannot verify subscriber information for the set-top box device 422, e.g., because it is connected to an unauthorized twisted pair, the client gateway 414 can block transmissions to and from the set-top box device 422 beyond the access network 416.
As indicated in
In an illustrative embodiment, content can be transmitted to the D-servers 444, where it can be encoded, formatted, stored, replicated, or otherwise manipulated and prepared for communication from the video server(s) 450 to the set-top box devices 422, 424. The CFT switch 442 can receive content from the video server(s) 450 and communicate the content to the CPE 418, 420 via the access network 416. In a particular embodiment, the content may include test data. The set-top box devices 422, 424 can receive the content via the CPE 418, 420, and can transmit the content to the television monitors 426, 428. In an illustrative embodiment, video or audio portions of the content can be streamed to the set-top box devices 422, 424.
Further, the AQT switch 468 can be coupled to a video-on-demand importer server 474 that receives and stores television or movie content received at the acquisition tier 406 and communicates the stored content to the VOD server 448 at the client-facing tier 402 via the private network 410. Additionally, at the acquisition tier 406, the video-on-demand (VOD) importer server 474 can receive content from one or more VOD sources outside the IPTV system 400, such as movie studios and programmers of non-live content. The VOD importer server 474 can transmit the VOD content to the AQT switch 468, and the AQT switch 468, in turn, can communicate the material to the CFT switch 442 via the private network 410. The VOD content can be stored at one or more servers, such as the VOD server 448.
When users issue requests for VOD content via the set-top box devices 422, 424, the requests can be transmitted over the access network 416 to the VOD server 448 via the CFT switch 442. Upon receiving such requests, the VOD server 448 can retrieve the requested VOD content and transmit the content to the set-top box devices 422, 424 across the access network 416 via the CFT switch 442. The set-top box devices 422, 424 can transmit the VOD content to the television monitors 426, 428. In an illustrative embodiment, video or audio portions of VOD content can be streamed to the set-top box devices 422, 424.
In an illustrative embodiment, the live acquisition server 470 can transmit content to the AQT switch 468, and the AQT switch 468, in turn, can transmit the content to the OMT switch 476 via the public network 412. In this embodiment, the OMT switch 476 can transmit the content to the TV2 server 478 for display to users accessing the user interface at the TV2 server 478. For example, a user can access the TV2 server 478 using a personal computer (PC) 464 coupled to the public network 412.
At 508, the wireless signal data and the packet stream data may be analyzed to produce an assessment of at least a portion of the wireless information delivery system. For example, the wireless signal data and the packet stream data may be correlated to determine a degree of correlation between the wireless signal data and the packet stream data. In a particular embodiment, a repair technician may create a current parameter map by mapping the wireless signal data and the packet stream data. The repair technician may troubleshoot a reported problem in a residential system by downloading an initial parameter map stored (e.g., at the OSS/BSS database 112) and comparing corresponding parameter values of the initial parameter map and the current parameter map to identify one or more differences that correlate to known causes (e.g., changed position of a set-top box, changed position of a wireless gateway, movement of furniture, or another cause of a symptom exhibited by the wireless information delivery system).
In a particular embodiment, the wireless signal data/packet stream data correlation may be determined by performing a first comparison of the wireless signal data to a signal parameter threshold and determining a wireless signal acceptability of the wireless signal data based upon the first comparison. A second comparison of the packet stream data to a packet stream parameter threshold may be performed and a packet stream acceptability may be determined based on the second comparison. The wireless signal acceptability may be compared to the packet stream acceptability to determine a degree of correlation between the wireless signal acceptability and the packet stream acceptability. In a particular embodiment, a suspected cause of a particular behavior of the wireless information delivery system may be determined based upon the wireless signal data/packet stream data correlation. In a particular embodiment, at 510, the wireless signal data and/or the packet stream data and/or the assessment may be compared to historical data, such as baseline data collected during installation of the wireless information delivery system, as part of a troubleshooting procedure applied to the wireless information delivery system. For example, RSSI may be measured at a particular location of a set-top box within a subscriber premises and may be compared with the RSSI that was measured and recorded at installation. A decrease of the RSSI by a particular amount, e.g., 10 decibels (dB), may prompt the service technician to verify that the wireless set-top box has not been relocated since installation. In another example, a change in configuration or use of the set-top boxes within the subscriber premises may be detected by comparing measurements of RSSI, a count of wireless set-top boxes, and/or a frequency of use of each of the currently installed wireless set-top boxes to historical data recorded during installation, and may prompt the service technician to relocate a particular wireless set-top box, change a wireless connection to a wired connection, or perform another action at the subscriber premises. The method ends at 512.
At 602, N positions at which to record measurements during a particular time period are identified within a particular space, such as a residence or other premises associated with a subscriber. For example, the particular space may be a household within which a wireless information delivery system is operable. At 604, an index n is set equal to 1. At 606, predefined test data may be caused to be transmitted as a packet stream sent via the wireless information delivery system. The packet stream received via a wireless signal may correspond to the predefined test data. For example, the transceiver 106 of
Proceeding to 612, the value of the wireless signal parameter and the value of the packet stream parameter measured at the nth geographic location are stored. Advancing to 614, the index n is incremented by 1, e.g., by setting n=n+1. Proceeding to 616, if n is not equal to N (the total number of positions at which to make and record measurements), more measurements are to be taken and the method proceeds to 618. At 618, the analysis tool may be moved to the new nth predefined position. Returning to 606, predefined test data may be caused to be transmitted as a packet stream sent via the wireless information delivery system. The method then proceeds to detect and store the values of the wireless signal parameter and the packet stream parameter at the nth geographic position.
At 616, if n is equal to N, advancing to 620 (see
After the wireless signal data and the packet stream data are determined, additional processing may be performed based on the wireless signal data and the packet stream data. For example, at 624 the wireless signal data and the packet stream data may be analyzed by correlating the wireless signal data and the packet stream data to produce a wireless signal/packet stream correlation. At 626, a suspected cause of a particular behavior of the wireless information delivery system may be determined based upon the wireless signal/packet stream correlation. At 640, the correlated results may be stored. At 642, a record of a technician visit may be stored. The method ends at 644.
In another example of additional processing that may be performed based on the wireless signal data and the packet stream data, at 628, the wireless signal data may be compared to a signal parameter threshold in a first comparison. A wireless signal acceptability may be determined based on the first comparison. The packet stream data may be compared to a packet stream threshold in a second comparison. A packet stream acceptability may be determined based on the second comparison. The wireless signal acceptability may be compared to the packet stream acceptability to determine a degree of correlation. At 640, correlated results, such as the degree of correlation and/or wireless signal data and packet stream data may be stored and may be used, e.g., for troubleshooting by comparing to a correlation factor or wireless signal data and packet stream data determined at a future time. Proceeding to 642, a record of a technician visit to the particular geographic area may be stored for future reference, e.g., at an OSS/BSS database, such as the OSS/BSS database 112 of
In another example of additional processing that may be performed based on the wireless signal data and the packet stream data, at 630, the wireless signal data and the packet stream data may be stored at a subscriber information database, such as the OSS/BSS database 112 of
In another example of additional processing that may be performed based on the wireless signal data and the packet stream data, at 632, each signal parameter value and each packet stream parameter value may be compared to corresponding threshold parameter values to determine an assessment. For example, an initial parameter map stored at the OSS/BSS database 112 may be downloaded. Parameter values, such as the wireless signal parameter and packet stream parameter values, may be compared to corresponding parameter values (e.g., threshold parameters) stored in the initial parameter map.
Advancing to 634, when the assessment is determined to be unacceptable, at 636, a cause may be suggested based on the wireless signal parameter values and based on the packet stream parameter values. At 638, the assessment may be presented to a user (e.g., a repair technician). Returning to 634, when the assessment is determined to be acceptable, at 638, the assessment may be presented to the user. The method ends at 644.
Advancing to 708, when the assessment indicates that the wireless information delivery system may not be operating properly or correctly, one or more of the nodes or a residential gateway is moved to a different location within the subscriber premises, at 710. Returning to 706, the wireless information delivery system may again be tested and assessed. Proceeding again to 708, when the assessment indicates correct operation of the wireless information delivery system within the subscriber premises, an operations systems server/billing systems server (OSS/BSS) systems, such as OSS/BSS server 460 of
