Abstract

An embodiment of the current invention is directed to determining that a wireless-service subscriber using a given mobile computing device is likely to transition to another provider (“to churn”). A list of mobile computing devices that have communicated with the given mobile computing device is determined. A relationship-strength value for each mobile computing device in the list is determined. A risk value of the given mobile computing device is determined based on the relationship-strength values of each of the mobile computing devices in the list that have churned. If the risk value is not greater than a risk value threshold, the given mobile computing device is not likely to churn. If the risk value is greater than the risk value threshold, the given mobile computing device is likely to churn.

Dependent claims

Computer-readable media having computer-executable instructions embodied thereon that, when executed, enable a computing device to perform a method of identifying a first set of wireless-services subscribers who are more likely to transition to another provider (“churn”) than are those of a second set of wireless-services subscribers, wherein both of said first and second sets of wireless-service subscribers subscribe to services of the same provider, the method comprising:

for each mobile computing device in a given set of mobile computing devices, determining what other mobile computing devices it has communicated with, thereby resulting in an identification of a plurality of mobile-device pairs, each pair being made up of said each mobile computing device and another mobile computing device;
counting a number of communications involved in each mobile-device pair, thereby providing a sum of the number of communications involved in each mobile-device pair;
determining whether the sum of the number of communications involved in each mobile-device pair is greater than or less than a threshold number of calls;
for each mobile-device pair, when the sum of the number of communications involved is greater than the threshold number of calls, then calculating a relationship-strength value that is based at least on a ratio of the sum of the number of communications involved in the mobile-device pair and a total number of communications involving said mobile computing device, wherein the relationship-strength value quantifies a strength of a relationship between the mobile computing devices in the pair;
for each mobile-device pair, when the sum of the number of communications involved is less than the threshold number of calls, then setting the relationship-strength value for said each pair to a predetermined value that is the same for each pair having the sum of the number of communications less than the threshold number of calls;
determining a risk value for said each mobile computing device in the given set based on the relationship-strength values of each pair of the plurality of mobile computing devices containing said each mobile computing device and a mobile computing device that has churned;
and
determining the first set of mobile computing devices that are likely to churn by adding said each mobile computing device to the first set of mobile computing devices that are likely to churn when the risk value of each said mobile computing device is greater than a threshold risk value.

Computer-readable media having computer-executable instructions embodied thereon that, when executed, enable a computing device to perform a method of determining that a wireless-service subscriber using a given mobile computing device is likely to transition to another provider (“churn”), the method comprising:

identifying a list of one or more mobile computing devices that have communicated with the given mobile computing device;
for each of the mobile computing devices in the list, counting a number of calls between the mobile computing device in the list and the given mobile computing device, thereby providing, for each of the mobile computing devices in the list, a sum of the number of calls between the mobile computing device in the list and the given mobile computing device;
determining a relationship-strength value for each of the one or more mobile computing devices in the list, said relationship-strength value based on the sum of the number of calls between each of the mobile computing devices in the list and the given mobile computing device;
setting the relationship-strength value for each of the mobile computing devices in the list to a predetermined value when the sum of the number of calls is less than a threshold number of calls, and wherein the predetermined value is the same for each mobile device in the list having the sum of the number of communications less than the threshold number of calls;
determining a risk value of the given mobile computing device based on the relationship-strength values of each of the mobile computing devices in the list that have churned;
when the risk value is not greater than a risk value threshold, determining that the given mobile computing device is not likely to churn;
and
when the risk value is greater than the risk value threshold, determining that the given mobile computing device is likely to churn.

Computer-readable media having computer-executable instructions embodied thereon that, when executed, enable a computing device to perform a method of determining an incentive to provide a wireless-service subscriber using a given mobile computing device that is likely to transition to another provider (“churn”), the method comprising:

identifying a list of one or more mobile computing devices that have communicated with the given mobile computing device, said communication including voice calls, text messages, and picture messages;
for each of the one or more mobile computing devices in the list, counting a number of calls between a mobile computing device in the list and the given mobile computing device, thereby providing a sum of the calls between the mobile computing device in the list and the given mobile computing device;
determining a relationship-strength value for each of the one or more mobile computing devices in the list, said relationship-strength value based on the sum of calls between a mobile computing device in the list and the given mobile computing device divided by a total number of calls involving the given mobile computing device, wherein the relationship-strength value for each of the mobile computing devices in the list is set to a predetermined value when the sum of calls is less than a threshold number of calls, and wherein the predetermined value is the same for each mobile device in the list having the sum of the number of communications less than the threshold number of calls;
determining a risk value of the given mobile computing device based on the relationship-strength values of each of the mobile computing devices in the list that have churned, said risk value including the sum of the relationship-strength values of each of the mobile computing devices in the list that have churned;
if the risk value is not greater than a risk value threshold, determining that the given mobile computing device is not likely to churn;
and
if the risk value is greater than the risk value threshold,
(A) determining that the given mobile computing device is likely to churn and
(B) determining an incentive to provide to the user of the given mobile computing device, thereby, when said incentive is provided, decreasing the likelihood that the user will churn.
