Dynamically adjusting a data usage plan based on data usage statistics

Abstract

Embodiments enable data usage plans and data usage statistics to be shared among user computing devices. In some embodiments, a web service receives a schema populated with data describing the data usage plan from a mobile operator. The web service distributes the populated schema to the user computing devices, and subsequently distributes updated portions of the schema as the data usage plan is updated by the mobile operator. The web service may also collect the data usage statistics from the user computing devices and the mobile operator, reconcile any differences, and send synchronization notifications to the user computing devices based on the reconciliation. In some embodiments, users are able to view bandwidth consumption by a plurality of user computing devices sharing the same data usage plan.

DETAILED DESCRIPTION

(12) Referring to the figures, embodiments of the disclosure enable a centralized web service 108 to interact with user computing devices and mobile operators 111 to distribute data usage plans and to aggregate data usage statistics. For example, the web service 108 pulls information from the mobile operators 111 regarding customers (e.g., users 104) and pushes data usage plan changes or updates to a given user 104, segments of the users 104, or each of the users 104.

(13) In some embodiments, the web service 108 receives a schema 116 populated with data relating to a data usage plan from the mobile operator 111 and distributes the populated schema 116 to one or more of the user computing devices. The data usage plan represents the terms and conditions (e.g., data consumption allotment) under which the mobile operator 111 provides data transfer services to the user computing devices. As the mobile operator 111 updates portions of the data usage plan, the web service 108 may receive and synchronize only the updated portions of the schema 116 with the user computing devices, in some embodiments. For example, the web service 108 does not distribute the other portions of the schema 116 that were not updated.

(14) The web service 108 may further generate, monitor, collect, and/or receive the data usage statistics from the mobile operators 111 and from one or more of the user computing devices. The data usage statistics represent an amount of data consumed by the user computing devices under the data usage plan. The web service 108 reconciles any differences in the received data usage statistics, and sends a synchronization notification to the user computing devices based on the reconciliation.

(15) Referring to FIG. 1, an exemplary block diagram illustrates the web service 108 interacting with the mobile operator 111 and user computing devices. The user computing devices include, for example, a mobile computing device 102 and other computing devices 106. The user computing devices communicate over one or more networks 109. In some embodiments, one or more of the user computing devices are associated with a data usage plan. For example, a plurality of the user computing devices may share data consumption allotted under the same or common data usage plan.

(16) The user computing devices include any device executing instructions (e.g., as application programs, operating system functionality, or both) to implement operations and functionality. The user computing devices may include, for example, the mobile computing device 102 or any other portable device. In some embodiments, the mobile computing device 102 includes a mobile telephone (e.g., mobile telephone 404 in FIG. 4), laptop, tablet, computing pad, netbook, gaming device, e-reader, and/or portable media player. The other computing devices 106 may include less portable devices such as desktop personal computers, kiosks, and tabletop devices that have network connectivity capabilities. Additionally, each user computing device may represent a group of processing units. While aspects of the disclosure may be described herein with reference to the mobile computing device 102, the descriptions are applicable to any of the user computing devices.

(17) Communication to/from the user computing devices may occur using any protocol or mechanism over one or more of the networks 109. The networks 109 represent any infrastructure or other means for sending and/or receiving data. The networks 109 may include wired and/or wireless networks.

(18) One or more of the mobile operators 111 communicate with the web service 108 and/or the user computing devices via the network 109. Further, the user computing devices communicate with the web service 108, or other entity that performs the operations described herein as being associated with the web service 108. The web service 108 may further store, or have access to, a computer-executable schema component 122 and a computer-executable statistics component 124. Operation of the schema component 122 and the statistics component 124, when executed, is described below with reference to FIG. 2.

(19) For convenience in illustrating and describing FIG. 1, the mobile computing device 102 and the other computing devices 106 are associated with a common data usage plan of the user 104. For example, the mobile computing device 102 may represent the mobile telephone 404 of the user 104, while the other computing devices 106 may include a tablet and a laptop associated with the user 104.

(20) In some embodiments, the mobile computing device 102 has at least one processor 110, a memory area 112, and at least one user interface (not shown). The processor 110 includes any quantity of processing units, and is programmed to execute computer-executable instructions for implementing aspects of the disclosure. The instructions may be performed by the processor 110 or by multiple processors executing within the mobile computing device 102, or performed by a processor external to the mobile computing device 102. In some embodiments, the processor 110 is programmed to execute instructions such as those illustrated in the figures (e.g., FIG. 3).

(21) In some embodiments, the processor 110 represents an implementation of analog techniques to perform the operations described herein. For example, the operations may be performed by an analog computing device and/or a digital computing device.

(22) The mobile computing device 102 further has one or more computer readable media such as the memory area 112. The memory area 112 includes any quantity of media associated with or accessible by the mobile computing device 102. The memory area 112 may be internal to the mobile computing device 102 (as shown in FIG. 1), external to the mobile computing device 102 (not shown), or both (not shown). In some embodiments, the memory area 112 includes read-only memory and/or memory wired into an analog computing device.

(23) The memory area 112 stores, among other data, one or more applications 114. The applications 114, when executed by the processor 110, operate to perform functionality on the mobile computing device 102. Exemplary applications 114 include mail application programs, web browsers, calendar application programs, address book application programs, messaging programs, media applications, location-based services, search programs, and the like. The applications 114 may communicate with counterpart applications or services such as the web services 108 accessible via the network 109. For example, the applications 114 may represent downloaded client-side applications that correspond to server-side services executing in a cloud.

(24) The mobile computing device 102 further establishes and maintains one or more network connections 130 representing communication channels or other means for sending and/or receiving data over the network 109. Exemplary network connections 130 include, but are not limited to, Wi-Fi, cellular, tethered, BLUETOOTH brand communication, near-field communication (NFC), and more. The network connections 130 may also be categorized into voice, text, data, or other categories or types of network traffic.

(25) The memory area 112 further stores at least one schema 116. The schema 116 represents the data usage plan associated with the user 104 of the mobile computing device 102. For example, the user 104 has contracted with the mobile operator 111 to receive network data transfer services from the mobile operator 111. The data usage plan describes the services provided by the mobile operator 111, such as the amount of network data the user 104 can consume during a particular duration (e.g., a billing time period). For example, the data usage plan describes threshold values 118 associated with the network connections 130 of one or more devices of the user 104. The threshold values 118 represent the maximum amount of data consumption allotted under the data usage plan for the network connections 130. For example, one threshold value 118 may indicate the maximum amount of data consumption for a Wi-Fi connection, while another threshold value 118 indicates the maximum amount of data consumption for a cellular data connection.

(26) The schema 116 may be defined by the web service 108, by the mobile operator 111, or by another entity. In general, the schema 116 enables descriptions of the parts, components, services, features, or other aspects of the data usage plan including, but not limited to, multi-rate data plans, peak times, roaming rates, allotted data consumption per network connection 130, etc. In some embodiments, the schema 116 allows the mobile operators 111 to send out updated portions of the schema 116 corresponding to updated parts of the data usage plan.

(27) In some embodiments, the schema 116 includes a plurality of fields. Each of the threshold values 118 may be associated with one or more of the fields. For example, the fields may correspond to one or more of the following: peak times, off-peak times, peak time data consumption quota, off-peak time data consumption quota, peak time data consumption remaining, off-peak time data consumption remaining, a roaming rate and rules, a mobile operator name, a billing cycle type, a network connection type, identification of free hosts available for connection, a list of mobile hotspots, and any other elements or information pertaining to the data usage plan. The list of free hosts represents zero-rated or reduced cost hosts (e.g., visiting particular web sites does not count against the data usage plan).

(28) The schema 116 may also include fields supporting different billing rates per host accessed, per weekend, per night, friends and family rates, peak and off-peak rates, and more. The schema 116 also allows each mobile operator 111 the flexibility to define complex plans including broadly offered plans, and dynamic, short-term offers to specific users 104 likely to use a specific part or parts of the overall services. Other offers based on any combination of the metrics obtained are available to the mobile operator 111.

(29) The schema 116 stored by the mobile computing device 102 may also include fields corresponding to data usage statistics collected, generated, or received by the mobile computing device 102 and/or the mobile operators 111. For example, to facilitate sharing the data usage statistics among the mobile operators 111, web service 108, and/or user computing devices, the mobile operators 111, web service 108, and the user computing devices may populate the schema 116 with the data usage statistics.

(30) While the schema 116 may take any form or structure, the schema 116 may be implemented as XML schema. Appendix A includes an exemplary XML schema for use in aspects of the disclosure.

(31) The memory area 112 further stores exemplary computer-executable components such as a communications interface component 126 and a user interface component 128. In some embodiments, the communications interface component 126 includes a network interface card and/or computer-executable instructions (e.g., a driver) for operating the network interface card. In some embodiments, the communications interface is operable with near-field communication (NFC) tags.

(32) The user interface component 128 may include a graphics card for displaying data to the user 104 and receiving data from the user 104. The user interface component 128 may also include computer-executable instructions (e.g., a driver) for operating the graphics card. Further, the user interface component 128 may include a display (e.g., a touch screen display or natural user interface) and/or computer-executable instructions (e.g., a driver) for operating the display. The user interface component 128 may also include one or more of the following to provide data to the user 104 or receive data from the user 104: speakers, a sound card, a camera, a microphone, a vibration motor, one or more accelerometers, a BLUETOOTH brand communication module, global positioning system (GPS) hardware, and a photoreceptive light sensor. For example, the user 104 may input commands or manipulate data by moving the computing device in a particular way.

(33) Referring next to FIG. 2, an exemplary flow chart illustrates operation of the web service 108 to obtain and distribute data describing a data usage plan, or a portion thereof. While the operations illustrated in FIG. 2 are performed by the web service 108 in some embodiments, one or more of the operations may be performed by other devices, including any computing device local to, or remote from, the user 104. For example, the operations may be performed by a proxy device in communication with the web service 108. Alternatively or in addition, the operations illustrated in FIG. 2 may be performed by an operating system executing on the mobile computing device 102.

(34) At 202, the web service 108 receives, from at least one of the mobile operators 111, the schema 116 populated with data describing the data usage plan associated with one or more of the user computing devices. At 204, the web service 108 distributes the received, populated schema 116 to the user computing devices. Subsequently, the web service 108 may receive at 206 an updated portion of the schema 116 from the mobile operator 111. The updated portion of the schema 116 corresponds to an updated portion of the data usage plan. For example, the mobile operator 111 may update one or more of the following: roaming agreements, fallback plans, free hosts, mobile hotspots, and any other element and information pertaining to the user's data plan that has an impact on data usage, cost, and/or tariff.

(35) The web service 108 distributes only the received, updated portion of the schema 116 to the user computing devices at 208. In this manner, the mobile operator 111 is able to update portions of the data usage plan and push only those updated portions (e.g., not the entire data usage plan) to subscribers (e.g., user 104), thus reducing the amount of network data consumed. In embodiments in which there are multiple updated portions of the schema 116, the web service 108 may decide to distribute the updated portions in separate batches, such as at different times or during particular time intervals. In this manner, the web service 108 is able to take advantage of reduced cost network transfers (e.g., off-peak times) to reduce or at least manage the network data consumption of the user computing devices.

(36) Rather than distributing the populated schema 116 or portions thereof, the web service 108 may send a notification to the user computing devices to synchronize their version of the populated schema 116 with that of the web service 108. In such embodiments, upon receipt of the notification from the web service 108, one or more of the user computing devices may send a synchronization request to the web service 108. Upon receipt of the synchronization request, the web service 108 provides the populated schema 116 or updated portions of the schema 116 to the requesting user computing devices.

(37) In some embodiments, the web service 108 may store, or have access to, one or more computer-executable components for implementing one or more of the operations illustrated in FIG. 2. For example, the schema component 122, when executed by the web service 108, receives from the mobile operator 111 the schema populated with data describing the data usage plan associated with one or more of the user computing devices. The schema component 122 distributes the received, populated schema to the user computing device. Subsequently, the web service 108 receives, from the mobile operator 111, an updated portion of the schema 116. The updated portion of the schema 116 corresponds to an updated portion of the data usage plan (e.g., as updated by the mobile operator 111 such as when changing terms of the data usage plan). The schema component 122 then distributes only the received, updated portion of the schema 116 to the user computing device.

(38) In some embodiments, the web service 108 may further collect, reconcile, and distribute data usage statistics to the user computing devices. The data usage statistics may be viewed as a current or instant snapshot of the amount of data transmitted and/or received (e.g., consumed) by the computing devices of the user 104 that share the data usage plan. The web service 108 may collect information relating to text messages, data, voice calls, minutes used, voice over Internet Protocol (VoIP) usage, and any other element of usage consumed by, or that impacts, the user computing devices to produce the data usage statistics. The data usage statistics identify, to a granularity of time (e.g., per minute) or data (e.g., per kilobyte), how much data has been sent and/or received by the mobile computing device 102 or other user computing devices and over which network connections 130. Other data usage statistics are contemplated, however. For example, the data usage statistics may further identify the time and day of usage, location of usage, network connection 130, technology usage, the subscriber identity module (SIM) card or other user identity module used for dual SIM scenarios, the international mobile station equipment identity (IMEI) or other device identifier for multi-device scenarios, the Internet protocol (IP) address or other address of the access point used for Wi-Fi scenarios, the IP address or other address of the target computer (e.g., for whitelist/blacklists in data usage), the application responsible for the data transfer, etc. In some examples, the web service 108 tracks or monitors network data consumption by the user computing devices by compiling the data usage statistics directly (e.g., monitor network traffic) and/or by collecting the data usage statistics from the mobile computing device 102 (or other user computing devices) and/or the mobile operator 111.

(39) For example, the web service 108 may collect, monitor, or generate first data usage statistics 120 from the mobile computing device 102 and second data usage statistics 132 from the mobile operator 111. In some embodiments, the first data usage statistics 120 represent network data consumed under the data usage plan by the mobile computing device 102 as determined and/or measured (e.g., collected and stored) by the mobile computing device 102. For example, the mobile computing device 102 collects ongoing usage data relating to network data transfers, such as from device radios, drivers, and accelerometers.

(40) In other embodiments, the first data usage statistics 120 represent network data consumed under the data usage plan by each of the user computing devices, not just the mobile computing device 102. In such embodiments, the mobile computing device 102 receives updates of network data consumption by the other user computing devices sharing the same data usage plan. The second data usage statistics 132 represent network data consumed under the data usage plan by the mobile computing device 102 as determined and/or measured (e.g., collected and stored) by the mobile operator 111. In other embodiments, the second data usage statistics 132 represent network data consumed under the data usage plan by each of the user computing devices, not just the mobile computing device 102. In such embodiments, the mobile operator 111 monitors network data consumption by the other user computing devices sharing the same data usage plan. For example, the second data usage statistics 132 may represent the network data collectively consumed by the mobile telephone 404, tablet, and laptop of the user 104.

(41) In a further example, one or more of the mobile operators 111 collect data usage statistics corresponding to a plurality of data usage plans. In such an example, there may a plurality of sets of data usage statistics (e.g., one set for each data usage plan or user 104).

(42) In some embodiments, the mobile operator 111 may have more current and/or more accurate data usage statistics 120 for one or more of the user computing devices than the user computing devices. For example, the mobile operator 111 may have more current and/or more accurate data usage statistics 120 for particular network connections 130 than the user computing devices. The mobile operator 111 may push, or transmit upon demand, such data usage statistics 120 to the web service 108. The web service 108 integrates or otherwise reconciles the data from the mobile operator 111 and/or the user computing devices to produce the data usage statistics 120.

(43) For example, if differences exist in the data usage statistics received from the mobile computing device 102 and from the mobile operator 111 (e.g., the data from the mobile operator 111 may be 24-48 hours old), the web service 108 reconciles the differences to provide the user 104 with the most current information. Reconciling the differences includes, for example, examining time stamps or other collection dates and favoring, weighting, or choosing the more recently collected data. For example, the web service 108 may compare a timestamp associated with the first data usage statistics 120 and a timestamp associated with the second data usage statistics 132 to determine which of the data usage statistics is more recent or up-to-date. Based on the reconciling, the web service 108 may send a notification to one or more of the user computing devices. In such embodiments, upon receipt of the notification from the web service 108, one or more of the user computing devices may send a synchronization request to the web service 108. For example, the web service 108 identifies those user computing devices that have outdated data usage statistics.

(44) Upon receipt of the synchronization request from the user computing devices, the web service 108 provides the most recent or up-to-date data usage statistics to those requesting user computing devices. For example, the web service 108 may provide the second data usage statistics 132 (e.g., from the mobile operator 111) to the requesting user computing devices.

(45) In some embodiments, the web service 108 executes the statistics component 124 to collect and analyze the data usage statistics. The statistics component 124, when executed by the web service 108, receives the first data usage statistics 120 as collected by the user computing device and the second data usage statistics 132 as collected by the mobile operator 111. The statistics component 124 reconciles the first data usage statistics 120 and the second data usage statistics 132, and sends a synchronization notification to the user computing device based on the reconciliation. For example, if the statistics component 124 determines that the first data usage statistics 120 collected or maintained by the user computing device is out-of-date, the web service 108 sends the synchronization notification to the user computing device. In response to receiving the synchronization notification, the user computing device synchronizes the first data usage statistics 120 with the second data usage statistics 132 (e.g., compares timestamps associated with the first data usage statistics 120 and the second data usage statistics 132). For example, the user computing device may replace the first data usage statistics 120 with the second data usage statistics 132.

(46) The web service 108 may store the schema component 122 and the statistics component 124 on one or more computer storage media. Further, the schema component 122 and the statistics component 124 may execute independently of each other (e.g., not sequentially, or without interaction or dependency between the two components). For example, the schema component 122 and the statistics component 124 may each be executed by a separate thread.

(47) Referring next to FIG. 3, an exemplary flow chart illustrates operation of a computing device such as the mobile computing device 102 to collect and reconcile data usage statistics describing network data consumed under the data usage plan. While the operations illustrated in FIG. 3 are performed by the computing device of the user 104 in some embodiments, one or more of the operations may be performed by other devices, including any computing device local to, or remote from, the user 104. For example, the operations may be performed by a proxy device in communication with the computing device. As an example, the operations illustrated in FIG. 3 may be performed by an operating system executing on the mobile computing device 102.

(48) At 302, the computing device collects data usage statistics (e.g., the first data usage statistics 120) relating to the data usage plan. The first data usage statistics 120 represent network data consumption under the data usage plan by the computing device as determined by the computing device. The computing device stores the collected first data usage statistics 120 in, for example, the memory area 112. At 304, the computing device receives data usage statistics (e.g., the second data usage statistics 132) relating to the data usage plan. The second data usage statistics 132 represent network data consumption under the data usage plan by the computing device as determined by the mobile operator 111.

(49) At 306, the computing device reconciles the collected first data usage statistics 120 and the received second data usage statistics 132. For example, the computing device may compare timestamps associated with the first data usage statistics 120 and the second data usage statistics 132 to identify the more recent, or up-to-date, measure of network data consumption under the data usage plan. At 308, the computing device updates the first data usage statistics 120 based on the reconciliation. For example, the computing device may conclude that the first data usage statistics 120 are more recent and hence more accurately represent current, cumulative network data consumption than the second data usage statistics 132. In such an example, the computing device makes no changes to the collected first data usage statistics 120.

(50) As another example, the computing device may conclude that the second data usage statistics 132 are more recent and hence more accurately represent current, cumulative network data consumption than the first data usage statistics 120. In such an example, the computing device may replace the first data usage statistics 120 stored in the memory area 112 with the second data usage statistics 132.

(51) As described with reference to FIG. 3, the first data usage statistics 120 represent network data consumed by the computing device, as monitored by the computing device. In other embodiments, the first data usage statistics 120 may represent network data consumed by the computing device and the other computing devices 106 sharing the data usage plan. For example, the computing device may collect the first data usage statistics 120 by receiving at least a portion of the first data usage statistics 120 from these other computing devices 106 associated with the data usage plan. In such embodiments, after reconciling the data usage statistics (e.g., updating the first data usage statistics 120 with the second data usage statistics 132), the computing device may send the updated first data usage statistics 120 to the other computing devices 106 based on the reconciliation. Alternatively or in addition, the computing device may send a synchronization notification to the other computing devices 106 prompting those computing devices to synchronize the data usage statistics with those from the computing device.

(52) Referring next to FIG. 4, an exemplary user interface 402 on the mobile telephone 404 illustrates configuration options for importing data describing the data usage plan. In the example of FIG. 4, the user 104 is able to explicitly opt-in or opt-out of receiving the schema 116 populated with the data usage plan. For example, the mobile telephone 404 asks permission from the user 104 to retrieve the wireless plan details to help avoid overcharges. The user 104 checks a checkbox to import the populated schema 116. In response, the mobile telephone 404 requests the populated schema 116 from the mobile operator 111 and, upon receipt from the mobile operator 111, the mobile telephone 404 stores the populated schema 116 in the memory area 112.

(53) Referring next to FIG. 5, an exemplary user interface 502 illustrates completion of synchronization of data describing the data usage plan. In the example of FIG. 5, the user 104 has opted-in to obtaining, from the mobile operator 111, the schema 116 populated with the data usage plan that the user 104 and mobile operator 111 have agreed upon. The user 104 receives confirmation that the details of the data usage plan have been downloaded, as displayed in the user interface 502 of the mobile telephone 404. The populated schema 116 includes details of the data usage plan, such as the start date of the billing cycle. The user interface 502 in FIG. 5 further displays the start date of the billing cycle to the user 104. The user interface 502 also displays a message telling the user 104 how to check current usage and modify account settings.

(54) Referring next to FIG. 6, an exemplary user interface 602 illustrates a summary of network data usage with different types of network connections 130. While the proportions of the user interfaces 602, 702, 704, 706 illustrated in FIG. 6, FIG. 7A, FIG. 7B, FIG. 7C, and FIG. 8 are shown to conform to a screen of the mobile computing device 102 (e.g., the mobile telephone 404), the content displayed within the user interfaces 602, 702, 704, 706 may be shown in any format on any of the user computing devices.

(55) In FIG. 6, data usage for a plurality of the network connections 130 is shown to the user 104 in the user interface 602. In particular, data usage statistics 120 attributed to each of the network connections 130 is shown. For example, the amounts of data transmitted and/or received over a cellular network connection, a tethered network connection, a Hotspot network connection, and a Wi-Fi network connection are shown. The amounts of data are represented by proportionally-sized horizontal bars.

(56) The user interface 602 also displays the threshold values 118 associated with each of the network connections 130. The threshold values 118 are taken from the data usage plan. For example, the data usage plan indicates that the user 104 has a maximum of 5 gigabytes (GB) of data usage available for the cellular network connection, 2 GB of data usage for the tethered network connection, 1 GB of data usage for the Hotspot network connection, and an unlimited amount of data usage for the Wi-Fi network connection.

(57) The user interface 602 in FIG. 6 may also display a button or bar that, when selected by the user 104 (e.g., clicked or touched), the user interface 602 allows the user 104 to select options or other configuration settings for receiving notifications. The notifications are sent when the amounts of data transmitted and/or received over the various network connections 130 reaches particular values (e.g., set by the user 104, mobile computing device 102, mobile operator 111, or other entity).

(58) Referring next to FIG. 7A, an exemplary user interface 702 illustrates data usage by the mobile computing device 102 consuming network data under the data usage plan having a monthly limit. While the overviews of data usage illustrated in FIG. 7A, FIG. 7B, and FIG. 7C indicate that the data usage statistics 120 shown are per application 114, the user interfaces 702, 704, 706 may alternatively or in addition display an overview of aggregated data usage across the applications 114 on the mobile computing device 102. Further, the user interfaces 702, 704, 706 may alternatively or in addition display an overview of data usage per computing device of the user 104 or aggregated across a plurality of the computing devices of the user 104. For example, the different statistics may be shown in different tabs or tiles in the user interfaces 702, 704, 706. In an example involving a family or shared data plan, the statistics for each plan member may be shown in separate tiles.

(59) In FIG. 7A, the data usage statistics 120 include the amount of network data remaining for use (e.g., the remainder of the monthly limit specified by the data usage plan), the amount of network data used during the current billing period, and the quantity of time (e.g., days) remaining within the current billing period. The data usage statistics 120 also indicate a breakout of the data usage, such as the amount of data consumed under a cellular network connection versus the amount of data consumed under a Wi-Fi network connection.

(60) Referring next to FIG. 7B, an exemplary user interface 704 illustrates data usage by the mobile computing device 102 consuming network data under a pay-as-you-go data usage plan. In FIG. 7B, the data usage statistics 120 include the amount of network data consumption remaining for use (e.g., the remainder of the pay-as-you-go amount specified by the data usage plan), the amount of network data consumed recently (e.g., within the last 30 days), and the quantity of time (e.g., days) remaining. For example, the remaining cellular data consumption expires in 16 days. The data usage statistics 120 also indicate a breakout of the data usage, such as the amount of data consumed under a cellular network connection versus the amount of data consumed under a Wi-Fi network connection.

(61) Referring next to FIG. 7C, an exemplary user interface 706 illustrates data usage by the mobile computing device 102 consuming network data under the data usage plan with unlimited data usage. In FIG. 7C, the data usage statistics 120 include the amount of network data consumed recently (e.g., within the last 30 days). The data usage statistics 120 also indicate a breakout of the data usage, such as the amount of data consumed under a cellular network connection versus the amount of data consumed under a Wi-Fi network connection. The data usage statistics 120 also indicate a total amount of usage by the mobile computing device 102.

(62) Referring next to FIG. 8, an exemplary block diagram illustrates the mobile computing device 102 as the mobile telephone 404 having a tile for displaying the data usage statistics 120 to the user 104. The mobile telephone 404 displays a plurality of tiles (e.g., active tiles) that may be updated with the data usage statistics 120. In some embodiments, tiles represent tile user interface elements. In the example of FIG. 8, the mobile telephone 404 indicates that 78% of the allotment for text messages has been consumed, while 55% of the allotment for data usage has been consumed.

(63) Additional Examples

(64) In an example scenario, the user 104 has several user computing devices associated with the same data usage plan. For example, the user 104 has a smartphone, a tablet, and a basic cellular telephone. In this example, the user 104 also has two subscriber identity module (SIM) cards or other user identity modules (e.g., two universal integrated circuit cards), each associated with a different data usage plan. Over time, the user 104 moves the SIM cards among the smartphone, tablet, and cellular telephone. After the user 104 installs one of the SIM cards in one of the devices, aspects of the disclosure execute on that device to detect the new SIM card and to communicate with the mobile operator 111 associated with the SIM card to obtain the schema 116 populated with the data usage plan associated with the SIM card. The user 104 is then able to view details of the data usage plan associated with that SIM card, such as the allotments per network connection 130 and remaining data consumption for the current billing cycle.

(65) In another example scenario, the computing device may share the populated schema 116, or portions thereof, with other devices upon demand or request. For example, the user 104 may tether the computing device to a friend's computing device (e.g., configure the computing device to be a wireless access point). The friend's computing device communicates with the user's computing device to obtain the schema 116 populated with the data usage plan. The friend is then able to view an amount of data consumption remaining under the data usage plan associated with the user 104 thus enabling the friend to decide whether, and how much, network data may be consumed.
