CALL TRAFFIC DIAGNOSTICS IN TELECOMMUNICATIONS NETWORKS

Abstract

Telephone calls within one or more telephone networks (or portions thereof) are animated in real time as they occur, or over some past period in real time or at a user-selected speed. Each animated call displays the call's progress from its first connection to its final disconnection, along with intervening connection delays and transition events (e.g., transfers, holds, conferences, etc.). Animated display of multiple concurrent calls allows network administrators to easily and intuitively diagnose telephone network issues and more easily devise solutions, particularly where such display is provided in combination with concurrent measures of telephone network efficiency.

DETAILED DESCRIPTION OF EXEMPLARY VERSIONS OF THE INVENTION

[0030] Expanding on the discussion above, the system preferably collects call data (such as that in FIG. 3) in real time from one or more telephone networks, telephone carriers, routers, etc., and stores the call data in a database. Call data can differ in format and content from one telephone network to another, and the data can be processed to provide uniform content and format, if necessary. This may include mapping call data to the properties configured in the telephone network(s), and/or applying processing algorithms, to identify call segments and/or transitions between call segments. As a simple example, consider the telephone call of FIG. 1. The call segments are logged as separate calls, but can be identified as parts of the same telephone call because they have the same Global Call ID. The order of the segments can be determined by looking to their connection times. The transition between the segments might, for example, be generically logged as Call Split, which may be Transfer or Conference. To more specifically determine the transition, the Terminating Number of the second call segment might be compared to the Conference Bridge number set up in the telephone network. If the numbers match, the transition is Conference; if they differ, the transition is Transfer. Similar algorithms can be applied to determine other transitions where needed.

[0031] Data processing may also be performed to determine desired quality metrics across one or more call segments, and/or across an entire telephone call. Values for latency, jitter, packet loss, Mean Opinion Score, and/or other qualities may be retrieved from the telephone network (where available), stored, and processed as desired to generate the desired metric(s).

[0032] The system then constructs and animates a schematic depiction of one or more telephone calls in the telephone network(s), as exemplified by FIGS. 4a-4j, 5, and 6. Looking at FIGS. 4a-4j in greater detail, these illustrate an exemplary animation of the call represented by the first telephone call in FIG. 3 (the first two entries identified by Global Call ID 1):

(1) In FIGS. 4a-4c, the user at address (telephone number) 540-525-6816 calls the user at address (extension) 2389 at 10:30:01 AM, with these users (addresses) being depicted by corresponding caller and recipient elements. These elements are spaced by a delay element which grows as the telephone rings at address 2389. The lack of connection (the ringing of the telephone) at address 2389 is illustrated not only by the growing delay element, but also by the fill color of the caller element, and the presence of an icon depicting a ringing telephone in the recipient element. These are not the only means for communicating connection status; as suggested earlier, the connection or other status of an element may be communicated by its color or fill pattern, border thickness or line type, element shape, image consistency (i.e., static appearance versus pulsing/flashing or otherwise fluctuating), and/or by any icons associated with the element. Thus, as another example, if the incoming call fails one or more call quality metrics, the caller element might (for example) pulse in appearance.
(2) In FIG. 4d, a connection is made to address 2389 after 10 seconds of delay (ringing). The fill color of the caller element changes, and the icon in the recipient element changes to an image of a sound-emitting telephone. The delay (ring) time may be displayed in the delay element, provided the delay element has sufficient size to accommodate such display. If the delay element is too small, the delay time might be shown in a pop-up box/balloon if the user clicks on, or situates a pointer atop, the delay element. It is noted that the display of delays is highly valuable, as these can be a key reason for inefficiencies. As an example, numerous delay elements with no following call segment elements may indicate that callers disconnected because ring time was intolerable.
(3) In FIGS. 4e-4g, the first call segment element lengthens in the direction of the growing array as the call segment proceeds to completion, with its length being proportional to the call segment's connection time. The connection time is displayed in the call segment element as described above (i.e., it can be shown within the call segment element if there is sufficient area, or may otherwise be displayed upon a user's request). FIG. 4g shows the display when the call segment ends (when the connection to address 2389 ends), and a recipient icon is displayed to show an attempted connection to address 5026.
(4) FIGS. 4h-4j show the following call segment underway after a 5-second delay element (a transfer), as address 2389 transfers the call to 5026. Following a 5-second transition delay from the transfer, address 540-525-6816 is connected to 5026 for 3 minutes and 27 seconds, at which point disconnection occurs.

[0033] In FIGS. 4a-4j, the call segment elements are color-coded to provide information about the transitions by which the call segments were entered. Other means of communicating transitions may be used instead, e.g., by displaying symbols/icons and/or text adjacent the junctures between call segment elements, and/or by providing audio cues during animation (e.g., plating particular tones for particular transitions as they are rendered on the display screen).

[0034] Where telephone call quality or call segment quality is to be a displayed metric, a preferred display is to provide a small radar graph (also known as a spider graph) when a user clicks on, hovers a cursor over, or otherwise selects a relevant element in the call. The graph may then display multiple call quality indicia (e.g., latency, jitter, packet loss, and Mean Opinion Score), each on a separate one of the graph's axes extending from a common nexus. Selection of an element may also or alternatively provide other information within or adjacent the element (where such information is available), such as the device used by the caller and/or the recipient to make the call, whether the call is an audio call or video call, the codec used for the call, whether the call was in a queue (and if so, what was the wait time), etc.

[0035] Economic/accounting data may be represented in the display as well. As examples, the cost of each call might be shown at the end of the element array representing the call, in the recipient element, or elsewhere. The cost of each call segment (or delay) might be displayed within or adjacent the corresponding element. The system might also track and account for the costs of matters such as personal calls, idle users/addresses, missed calls, calls on hold, number of calls to voicemail, etc., and such matters might be displayed apart from the schematically-illustrated telephone calls (e.g., in the user interface of FIG. 5).

[0036] FIG. 5 shows an exemplary animated display that might be seen by a user of the system, wherein each of several telephone calls is displayed in a manner similar to the call shown in FIGS. 4a-4j, and a user interface is also provided to allow the user to select the period to be animated (or the moment to be shown), the animation speed, the calls to be displayed, and so forth. (Note that the displayed calls differ from the one shown in FIGS. 4a-4j in that once a call is completed, the recipient element is moved to the right side of the display screen, thereby allowing calls completed at the currently-displayed time to be more readily differentiated from calls which are still in progress at the currently-displayed time.) While only six calls are shown (corresponding to the data depicted in FIG. 3), the animated display might show fewer or far more calls.

[0037] The first displayed call corresponds generally to the call shown in FIGS. 4a-4j.

[0038] The second call shows a completed call to voicemail. When a user clicks on, hovers a cursor over, or otherwise selects the corresponding call segment element (or the voicemail icon shown in the recipient element), voicemail information might be displayed within or adjacent the element (where such information is available), such as whether the voicemail was read or remains unread, the length of the voicemail, whether a callback was made in response to the voicemail, etc. Some of this information might simply be conveyed by the color, size, or other appearance characteristics of the voicemail icon (e.g., the voicemail icon may darken or fade in dependence on whether the voicemail has been accessed).

[0039] The third call shows a connection to a hunt group at address/number 2774, with the different hunt group members having their addresses/numbers shown in different colors or formats to illustrate their status (e.g., 4261 being shown in green to illustrate available status, 2345 being shown in orange to illustrate away status, and 3374 being shown in red to illustrate busy status. When the call was ringing to 2774, 4261 answered the call with a 15 second delay and the other two users were not available to accept a call. The final call segment prior to termination is a conference call, and displays the addresses/numbers of all attendees at the moment the call is depicted, with different colors, formats, or the like illustrating an attendee's status. Thus, attendee addresses/numbers may appear or disappear as attendees join or leave; an attendee's transfer to another address/number might be depicted as, for example, 3472->3800; an attendee added to the conference by a participant-attendee rather than the host-attendee might have its address/number displayed in parentheses; and so forth. As an example, if 3372 added 3800 to the conference, these attendees might be depicted as 3372 (3800), with 3800 being shown in parentheses because 3800 is sharing audio with 3372. If 3372 disconnects from the conference (and thus disappears from the call segment element), then 3800 will also get disconnected, and will disappear.

[0040] The fourth call shows a completed call to 2389, whereas the fifth call shows an in-progress call to 3565. The sixth call is an attempted (but not yet connected) call to 9356.

[0041] In the user interface of FIG. 5, forward and reverse buttons allow a user to index through time intervals (here half-hour intervals), and a play/pause button allows a user to play the animation of the telephone call data over the selected interval. While not depicted, a user might be able to enter some interval having desired start and finish times. A slider button allows a user to move to any desired moment within the interval. Speed settings allow a user to increase or decrease animation speed from a default real-time speed. The calls to be displayed may also be filtered in accordance with selected criteria, with other filter criteria being possible (e.g., selection of all calls handled by one or more specific addresses or trunks). While not shown, the interface might also allow the user to scroll through all telephone calls selected for viewing, and zoom in and out to display fewer or more of the calls.

[0042] The user interface may also display summaries of aspects of telephone network performance; in FIG. 5, these are provided by usage meters showing trunk utilization (how many concurrent calls are being handled by a trunk line), the amount of calls going to voicemail, and call quality. The usage meter displays are updated to show telephone network metrics at the time currently being animated. These usage meters (or other means of displaying metrics) may display alerts if certain conditions are met, e.g., the trunk utilization meter may turn red or flash if one or more trunks are approaching critical capacity or are overloaded. The illustrated metrics are merely exemplary, and other metrics related to call traffic, usage patterns, hunt group efficiency, etc. might be provided, and might be provided in forms other than the illustrated meters (e.g., a histogram might be displayed showing the distribution of hold times for calls on hold). The metrics, in conjunction with the display of call traffic, allow network administrators to more easily discern telephone network issues and devise solutions. For example, in FIG. 5, the usage meters depict high trunk utilization and low call quality. A network administrator might review the call traffic animation to see whether the two metrics are correlated, and whether certain call traffic events are having greater impact on one or more of the metrics.

[0043] FIG. 6 illustrates the schematic telephone calls as they might appear on the animated display if the user zooms out. When numerous calls are simultaneously depicted in this manner and animated, network administrators, human resource managers, and others can readily identify patterns and issues. The depiction of telephone calls by their call segments and delays (as well as their callers and final recipients), and the timewise growth of the elements representing these matters, provides an intuitive and easy way to visualize call traffic.

[0044] More advanced versions of the inventive system might incorporate machine learning to predict usage patterns based on trafficfor example, trunk line usage, voicemail usage, hunt group usage/efficiency, etc.and recommend alternatives or solutions to issues (e.g., route pattern advice, load balancing of trunks if certain trunk lines are utilized to its max capacity while others are underutilized, voicemail port usage advice, hunt group efficiency advice, etc.). A preferred approach is to show animated call flow as in the accompanying drawings alongside an animation of the predicted performance of the telephone network if recommendations (or user-proposed solutions) are implemented. The system might also implement automated optimization of the telephone network based on machine learning suggestions.

[0045] The invention is not intended to be limited to the preferred versions of the invention described above, but rather is intended to be limited only by the claims set out below. Thus, the invention encompasses all different versions that fall literally or equivalently within the scope of these claims.
