Advice of promotion for usage based subscribers

Abstract

Systems and method are described for providing advice of promotion to notify a subscriber about potential promotions that the subscriber would benefit from if he/she changed the context under which he/she plans to use a service. The process begins when a subscriber initiates a request to use the service, e.g. establish a call session. The operator identifies the subscriber by determining whether the subscriber is permitted to use the service, e.g. establish the session, and calculates a charge rate for the service usage, e.g. call session based on a usage plan associated with the subscriber. A rating engine is then invoked to identify a promotion that includes an additional rate that is different from the charge rate determined for the session. The promotion is identified based on parameters associated with the call session by determining which additional rate would apply if at least one of those parameters were modified.

FIELD OF INVENTION

The current invention generally relates to usage charging such as in wireless telecommunications and more particularly to billing systems and subscriber usage plans.

BACKGROUND

Cellular telephone plans and other usage based service plans often include promotions for the customers. For example, phone calls made after a certain hour, or during the weekend may be less expensive than phone calls made during regular business hours. Telecom operators and other service operators often define these promotions to encourage subscribers to use the services under the condition of promotions. For example, a telecom operator whose network is less loaded during the weekend may create weekend promotions to encourage their subscribers to make lower priority phone calls during the weekend, so as to offload the network during the week. The same example applies for an electricity provider or any other service provider.

Today, it is the responsibility of the subscribers to remember the conditions under which they can receive promotions. There exists an advice of charge mechanism to notify subscribers upfront regarding the cost of the usage of a service under the current condition (time of day, location, etc). With advice of charge, subscribers can be informed about the cost of the service usage before accessing that service. However, the advice of charge mechanism is generally not capable of advising the subscriber of potential promotions he could potentially benefit from.

SUMMARY

In accordance with various embodiments of the invention, systems and method are described for providing advice of promotion which can be used to notify a subscriber about potential promotions that the subscriber would benefit from if he/she changed the context under which he/she plan to use a service. For a wireless subscriber, the process begins when a subscriber first initiates a request to use a service (e.g., establish a call session) by using a device such as a wireless device. The request is received by the telecom operator. The operator systems identify the subscriber by determining whether the subscriber is permitted to use the service. In addition, the systems determine a charge rate for the service usage based on a plan associated with the subscriber using a rating engine. As the rating engine is invoked to identify the rate for the usage, it can also calculate the rate for another set of parameters associated with the service usage and determining which additional rate would apply if at least one of those parameters were modified. If a different rate is identified, the operator can then transmit a response to the subscriber that includes information about the promotion identified by the rating engine. This information can be used to notify the subscriber of the additional promotions he/she could benefit if he/she changed its usage condition.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is an illustration of a system that provides advice of promotion, in accordance with various embodiments of the invention.

FIG. 2 is an illustration of the runtime rating model graph used by the rating engine, in accordance with various embodiments of the invention.

FIG. 3 is a flow chart illustration of a process for providing advice of promotion, in accordance with various embodiments of the invention.

DETAILED DESCRIPTION

In accordance with various embodiments of the invention, techniques are described which can be used to analyze the current context under which a subscriber is planning to use a service (e.g. plans to make a telephone call) in order to not only notify that subscriber about charges, but to also notify of potential promotions that the subscriber would benefit from if he/she changed the context under which he/she plan to use the service.

By way of illustration, a subscriber may be signed up for a price plan where phone calls cost 5 cents/minute before 6:00 PM and 1 cent/minute after 6:00 PM. If the subscriber is planning to make a phone call at 5:55 PM, the system would notify the subscriber that the cost of making this call at the current moment is 5 cts/min (advice of charge), and, additionally that in 5 minutes from now (at 6:00 PM) it would cost only 1 cts/min (advice of promotion).

As another illustration, a subscriber may be signed up for a price plan where phone calls cost 5 cents/minute except for calls made from non busy locations (e.g. where cell towers are under used). If a subscriber to this price plan is planning on making a phone call, the system would notify the subscriber that the cost of making this call at the current moment is 5 cts/min (advice of charge), but in addition that if this call was made from another location near by, such as from an adjacent cell, then the call would cost only 2 cts/min.

In this manner, the advice of promotion system provides an improved user experience and enables the subscriber to better control the charges and phone plan.

In accordance with an embodiment, the system can include a rating engine that can be instructed to calculate alternative rate(s) by varying the context of the usage. The rating engine runtime rating model is a graph, whose nodes are conditions and leaves are the rates. The conditions and the rates are derived from the rate plan information and include reference to the context (subscriber data, usage data) that provides values for evaluating the conditions. When the rating engine processes a request, the rating graph is executed against the usage current context which efficiently leads to the determination of the rate for this context. The enhancement to the rating engine is to instruct it to evaluate alternative acceptable condition changes that will lead to different rate.

When the rating engine processes a service usage request, it executes the rules in the context of the current usage request. In accordance with an embodiment, the context includes but is not limited to (1) parameters of the request (type, quantity, etc.); (2) parameters of the customer/subscriber (tariffs, price plans, accumulated usage, contracts, etc.); and (3) other parameters (time-of-day, taxes, etc.).

The conditions that are under the control of the end user (time of the call, location, etc), are tags and their acceptable variations are configured, so during the evaluation of the conditions, the rating engine detects the one that could lead to different rates and evaluate them. If any better alternative rate under the changed conditions is calculated, the new rate(s) and the service usage condition(s) would be used to advise the user of a promotion about the service to be rendered. It should be noted that this advice of promotion could be calculated and used before, during and after a service has been rendered.

FIG. 1 is an illustration of a system that provides advice of promotion, in accordance with various embodiments of the invention. Although this diagram depicts components as logically separate, such depiction is merely for illustrative purposes. It will be apparent to those skilled in the art that the components portrayed in this figure and in other figures can be combined or divided into separate software, firmware and/or hardware. Furthermore, it will also be apparent to those skilled in the art that such components, regardless of how they are combined or divided, can execute on the same computing device or can be distributed among different computing devices connected by one or more networks or other suitable communication means.

As illustrated, a telecom operator 100 can provide telephone as well as other services to a number of subscribers (103, 104). Each subscriber typically has a usage plan (106, 107) or some charge rates associated with them. When one subscriber 103 initiates a telephone call to another subscriber, the operator will typically identify the subscriber by determining whether that particular subscriber is permitted to establish the call session. In addition, the operator will determine a charge rate for the call session based on the usage plan 106 associated with the subscriber 103.

In accordance with an embodiment, the operator can deploy a rating engine 102 that can be used to identify various additional promotions for the subscriber. The additional promotions may include different rates from the charge rate determined for the session being requested by the subscriber. The rating engine can employ a runtime rating model 108 to identify the promotion(s) by analyzing a set of parameters associated with the call session and determining which additional rate would apply if at least one of those parameters were modified. Once the promotion has been identified, it can be attached to the response transmitted to the subscriber that is requesting the call session. The response can include information about the promotion identified by the rating engine, which can be used to notify the subscriber using the device (e.g., a wireless device).

FIG. 2 is an illustration of the runtime rating model graph used by the rating engine, in accordance with various embodiments of the invention. As illustrated, the runtime rating model can be a graph 208 whose nodes (200-204) are conditions and leaves (205-207) are the rates. The conditions and the rates are derived from the rate plan information and include reference to the context (subscriber data, usage data) that provides values for evaluating the conditions. When the rating engine processes a request, the rating graph is executed against the usage current context which efficiently leads to the determination of the rate for this context. The rating engine can be instructed to evaluate alternative acceptable condition changes that will lead to a different rate(s).

FIG. 3 is a flow chart illustration of a process for providing advice of promotion, in accordance with various embodiments of the invention. Although this figure depicts functional steps in a particular sequence for purposes of illustration, the process is not necessarily limited to this particular order or steps. One skilled in the art will appreciate that the various steps portrayed in this figure can be changed, rearranged, performed in parallel or adapted in various ways. Furthermore, it is to be understood that certain steps or sequences of steps can be added to or omitted from this process, without departing from the spirit and scope of the invention.

As shown in step 300, a subscriber first initiates a request to establish a call session by using a device (e.g., a wireless device). The request is received by the telecom operator. In step 301, the operator identifies the subscriber by determining whether the subscriber is permitted to establish the call session. In addition, the operator determines a charge rate for the call session based on a plan associated with the subscriber. In step 302, a rating engine is invoked to identify a promotion that includes at least one additional rate that is different from the charge rate determined for the session. The rating engine identifies the promotion analyzing a set of parameters associated with the call session and determining which additional rate would apply if at least one of said parameters were modified. In step 303, the operator transmits a response to the subscriber that includes information about the promotion identified by the rating engine. This information can be used to notify the subscriber of the additional promotions.
