A first network device receives multiple subscription data campaigns, where each of the multiple subscription data campaigns comprises media content, a free data usage quota, and a price for receiving the media content, presents the multiple subscription data campaigns to a user device associated with a user, and receives a selection of one of the multiple subscription data campaigns from the user device. The first network device receives, from a second network device, an indication that the user has successfully subscribed to the selected one of the multiple subscription data campaigns, where the second network device hosts media content associated with the selected one of the multiple subscription data campaigns, generates an authorization token that includes an identifier of the user, an identifier of the selected one of the multiple subscription data campaigns, and the free data usage quota, and sends the authorization token to the second network device. |

1. A method, comprising:
receiving, at a first network device, multiple subscription data campaigns, wherein each of the multiple subscription data campaigns comprises media content, a free data usage quota, and a price for receiving the media content; presenting, by the first network device, the multiple subscription data campaigns, via a network, to a user device associated with a user; receiving, at the first network device, a selection of one of the multiple subscription data campaigns from the user; sending, from the first network device to a second network device, data identifying the user and data identifying the selected one of the multiple subscription data campaigns; retrieving, at the second network device, a user profile associated with the user; granting, at the second network device, a subscription to the selected one of the multiple subscription data campaigns based on applying a set of campaign subscription rules to the retrieved user profile,
wherein the retrieved user profile includes data related to usage of previously allocated free data by the user, and wherein applying the set of campaign subscription rules comprises applying at least one first campaign subscription rule of the set of campaign subscription rules to the data, related to usage of previously allocated free data, to determine how much of the previously allocated free data was used by the user and wherein granting the subscription is further based on how much of the previously allocated free data was used by the user; sending a message, from the second network device to the first network device, that indicates that the user has successfully subscribed to the selected one of the multiple subscription data campaigns; generating, at the first network device, an authorization token that includes an identifier of the user, an identifier of the selected one of the multiple subscription data campaigns, and the free data usage quota; encrypting, at the first network device, the authorization token; sending, from the first network device to the second network device, the encrypted authorization token; and delivering, from the second network device to the user device, media content associated with the selected one of the multiple subscription data campaigns. |
