The invention relates to service provider monitoring of customer data usage and mores specifically to automatic top-up of customer data quotas.
Network service providers, such as Internet Service Providers (ISPs) provide data service plans that specify upload and download rates as well as quotas as to how much data may be transferred during a contractual period.
When a customer reaches their contracted quota ongoing data services are typically blocked pending the contractual arrangement of a new quota.
As a particular customer quota limit may be reached at any time in a given period dependent upon previous cumulative usage, and given the delays and costs associated with having to take manual action to arrange a new contractual quota, it would be desirable to have a system and method that improved upon existing methods of enforcing metered data limits that minimizes the drawbacks and limitations of the present art.
It is an object of the invention to provide a method and system for customer metering quotas which provides for automatic metering quota top-ups.

The techniques shown in the figures can be implemented using code and data stored and executed on one or more electronic devices (e.g., a network element). Such electronic devices store and communicate (internally and with other electronic devices over a network) code and data using machine-readable media, such as machine storage media (e.g., magnetic disks; optical disks; random access memory; read only memory; flash memory devices) and machine communication media (e.g., electrical, optical, acoustical or other form of propagated signals—such as carrier waves, infrared signals, digital signals, etc.). In addition, such electronic devices typically include a set of one or more processors coupled to one or more other components, such as a storage device, one or more user input/output devices (e.g., a keyboard and/or a display), and a network connection. The coupling of the set of processors and other components is typically through one or more busses and bridges (also termed as bus controllers). The storage device and signals carrying the network traffic respectively represent one or more machine storage media and machine communication media. Thus, the storage device of a given electronic device typically stores code and/or data for execution on the set of one or more processors of that electronic device. Of course, one or more parts of an embodiment of the invention may be implemented using different combinations of software, firmware, and/or hardware.
As used herein, a network element (e.g., a router, switch, bridge, etc.) is a piece of networking equipment, including hardware and software that communicatively interconnects other equipment on the network (e.g., other network elements, computer end stations, etc.). Customer computer end stations (e.g., workstations, laptops, palm tops, mobile phones, etc.) access content/services provided over the Internet and/or content/services provided on associated networks such as the Internet. The content and/or services are typically provided by one or more server computing end stations belonging to a service or content provider, and may include public webpages (free content, store fronts, search services, etc.), private webpages (e.g., username/password accessed webpages providing email services, etc.), corporate networks over VPNs, etc. Typically, customer computing end stations are coupled (e.g., through customer premise equipment coupled to an access network, wirelessly to an access network) to edge network elements, which are coupled through core network elements of the Internet to the server computing end stations.

Communication network 103 may be a network (e.g., the Internet or another network of communications devices) for providing data communications between user equipment 102 and other devices connected to communication network 103. Communication network 103 may further provide, for example, phone and/or Internet service to various user devices in communication with communication network 103.
Customer equipment 102 may be a device that communicates with communication network 103 for providing an end-user with a data service. Such data service may include, for example, voice communication, text messaging, multimedia streaming, and Internet access. More specifically, in various exemplary embodiments, customer equipment 102 is a personal or laptop computer, wireless email device, cell phone, television set-top box, or any other device capable of communicating with other devices via edge network element 104.
Edge network element 104 may be a router, switch, bridge, or similar networking equipment, including hardware and software that communicatively interconnects customer equipment 102 to other equipment on the network.
Monitoring network element 106 may be a device that monitors customer usage and manages customer sessions based on customer policies and usage information. One example of monitoring network element 106 is the Alcatel-Lucent 5750 Subscriber Services Controller which administers subscriber entitlements, service definitions and policies (rules) to perform functions including Network Access Control—subscriber and device authentication, IP address management for home devices, subscriber location information for presence-based applications; On-Demand Service Control—automated computation of the required network resources to support the changing subscriber's multimedia service mix & options and dynamic implementation of the resulting policies using RADIUS, DHCP protocols or EMS adaptation; and Application Admission Control—accept or deny IMS and non-IMS on-demand application requests based on revenue priority and bandwidth availability in the wireline network.
In operation, the user equipment 102 is associated with a customer having a customer plan which provides for a specified quota of data transfer. The quota establishes a quantitative ceiling under which cumulative usage must remain for a given contractual period. Edge network element 104 communicates customer data usage to monitoring network element 106 which calculates cumulative customer data usage and compares it to the quota established in the respective customer plan.
According to an embodiment of the invention there is provided an initial quota which can be supplemented by top-up quota increments in the event that cumulative customer data usage exceeds the initial quota. Referring now to
An important aspect of Table 1 is the way in which the top-ups are represented in terms of a percentage of the initial quota. When cumulative customer data usage is calculated as a percentage of the initial quota and communicated to the customer, the customer is better able to gauge the extent to which the initial quota associated with their chosen plan represents their actual data usage. For example, a customer choosing Plan A whose cumulative data usage totaled 60 G would be notified that they were using 200% of their plan quota, and that the next quota threshold would be at 433%. This would enable them to assess the utility of upgrading to a different plan having a higher initial quota threshold.
Referring now to
This sequence of flows is repeated at flows 316, 318, 320, and 322 for instances wherein the monitoring network equipment continues to confirm that cumulative customer data usage is below the initial threshold.
At 324 a customer data transfer is reported at 326 and at 328 monitoring network element 306 determines that cumulative customer data usage exceeds the initial threshold. According to the associated customer plan, the initial threshold is topped up and set to a new threshold corresponding to the base quota plus the top-up amount. A notification is sent to the customer that the quota has been exceeded and a top-up performed and at 330 an acknowledgement for accounting message is sent.
At 332 subsequent customer data transfers occur, and are reported at 326. The resultant cumulative customer data usage is calculated and compared against the new threshold. Having confirmed that the cumulative data usage is below the new threshold, monitoring network element 306 then provides an acknowledgement for the purposes of accounting messaging at 338.
Subsequent repetitions of this latter sequence may occur.
At 340 a customer data transfer occurs, and the usage is reported at 342, and the monitoring network element calculates the cumulative customer data usage and determines that the new threshold is exceeded, Should there be additional top-ups remaining in the associated customer plan, monitoring network element 306 will perform the appropriate top-up and calculate a new associated threshold and proceed as per flow 338. However, in the event that there are no top-ups remaining in the associated customer plan, monitoring network element 306 will notify the customer that they have reached their cumulative data quota according to their plan at 344. Monitoring network element 306 will then instruct edge network equipment 304 to perform a redirect of customer user data communications at 346. Edge network equipment 304 then acts to block outgoing data communications from customer equipment 302 to other elements in the network and redirects customer data requests to a predefined page at 348. The predefined page could, for example, contain instructions as to how the customer could have their data quota further increased.
Referring now to
In the event that the calculated percentage is less than the initial threshold, then control returns to step 410 for further usage metering.
In the event that the calculated percentage is equal to or greater than the initial threshold, control proceeds to step 418 where a check is performed as to whether there remains a top-up quantity according to the associated customer plan.
In the event that the check results of step 418 are affirmative, then at step 420 the appropriate top-up quantity is added and at step 422 the threshold is recalculated.
According to some embodiments of the invention the new threshold is calculated as a percentage of the total sum of the base quota plus applied top-ups, relative to the base quota amount provided for in the associated plan.
This may be expressed in formula form as:
At step 424 an optional message is provided for accounting purposes and at step 426 an optional notification message is provided to the customer associated with the customer plan. Control then returns to step 410 for further usage metering.
In the event that the check results of step 418 are negative, i.e. there are no further quota top-ups remaining according to the associated customer plan, then further customer data transfers are blocked at step 428 and attempts for customer data transfers are redirected at step 430. In some embodiments the redirection is to data, such as a web page, which provides further instructions as to measures the customer may take to obtain either a further quota increase, or other measures so that customer data transfers may resume.
According to the foregoing, various exemplary embodiments provide for a method and system that of enforcing metered customer data usage limits. In particular by providing for automatic quota top-ups when cumulative customer data transfers exceed contractual limits the drawbacks of service interrupting and manual intervention are obviated.
