The invention relates to a wireless service provider system and method for the sale and activation of wireless services on wireless devices. More particularly, the invention relates to methods for provisioning wireless services on wireless devices using a communication protocol.
A large number of wireless service plans exist for customers desiring wireless services such as data, talk, and text messaging. To obtain these wireless services, customers generally have the option of entering into a post-paid service, e.g., contract for a period of time, or a pre-paid, contract-free service. The latter offers customers the freedom to initiate and stop wireless services without incurring expensive cancellation fees associated with a post-paid service.
Generally, companies that provide post-paid wireless services are wireless carriers or Mobile Network Operators (MNO) that maintain and control their own wireless networks. A MNO heavily relies on backend systems to address any provisional, billing, security and data issues that might threaten the health of their networks. On the other hand, a Mobile Virtual Network Operator (MVNO) is a mobile operator that typically does not own its own frequency spectrum or have its own network infrastructure. MVNOs negotiate and enter into business agreements with third party wireless carriers or MNOs to purchase the right to use their networks for wireless services including volume of data and number of minutes/text messages used.
The services provided by both the MNOs and MVNOs often implement activation cards, also known as airtime cards, for the sale and activation and/or addition of a wireless service, e.g. talk airtime, data, or text messaging. Activation cards generally include a unique code that may include a scratch off area obscuring the unique code. Codes are correlated to a wireless service and must be recorded in a service provider's database prior to distributing the activation card to a respective point-of-sale and reaching the customer. A record of every airtime card distributed is therefore kept for the activation of the corresponding wireless service until the card becomes obsolete through redemption or expiration. Once a card is sold to a user, the user must manually scratch off the covering of the code and manually enter the code and for activation of the wireless service. Codes are generally made long and complex to prevent unauthorized use of the codes to activate non-purchased wireless services.
Convenience, timeliness, and reliability of the wireless providers' backend systems are key factors that play into a user's experience. By developing a system to improve at least these factors, a more positive experience can be provided to the user. The improved experience will help retain customer base and increase the amount of customers willing to purchase wireless services from MNOs and MVNOs. In order to do so, the following needs can be addressed by enabling new improved systems that can be implemented for the activation of a wireless service.
A need exists to decrease the amount of processing of the backend systems of wireless providers to provide faster activation of wireless services. Another need in the art also exists for an error free and more expedient method and system for customers to extend cellular services without using airtime cards. A further need exists in the art for a method, system and application to enable wireless providers and retailers to sell and authenticate wireless services in convenient locations, including transient locations, in an expedited manner, and without compromising unauthorized activation of services or the security of the wireless providers' backend systems.
Accordingly, a more convenient, secure, and time efficient approach is needed for the sale and activation of wireless services.
The foregoing needs are met, to a great extent, by the invention, providing a system and associated methods for activating services and subscriptions on wireless devices and/or systems implementing a communication interface to connect with a point-of-sale terminal via a communication protocol such as a peer-to-peer protocol or similar protocol. In particular, the invention is intended to solve the challenges by using a communication interface on a wireless device with at least one unique identifier that corresponds to a purchased/selected wireless service and/or subscription. According to some aspects of the disclosure, the services requested to be activated may include at least one of initial provisioning or activation, device upgrades, device reactivations, wireless number changes, the addition or purchase of services including airtime, data and text messaging, enrollments or content, and wireless number porting for wireless devices that have already been activated.
According to aspects of the disclosure a wireless service provider system for authorizing wireless service on a wireless device includes a point-of-sale terminal, a peer-to-peer protocol configured to connect the wireless device and the point-of-sale terminal, a unique identifier of the wireless device, at least one application associated with the wireless device configured to provide the unique identifier of the wireless device, the least one application of the wireless device further configured to conduct transactions from the wireless device to the point-of-sale terminal, and a processor of the wireless device configured to execute the first application and second application of the wireless device.
According to further aspects of the disclosure, a method of authorizing wireless service using a peer-to-peer protocol includes connecting a wireless device to a point-of-sale terminal through the peer-to-peer protocol, selecting at least one wireless service, making a payment, in response to the selection of at least one wireless service, for the at least one wireless service from the wireless device to the point-of sale terminal, activating, in response to making a payment, the unique identifier, confirming, in response to activating the unique identifier, activation of the unique identifier, and activating the at least one wireless service.

In some aspects, all of the codes, e.g. first code—third code, may be programmed to provide a unique identifier of the wireless device 104 during manufacturing and prior to distribution. However, in some aspects, only the first code may be programmed during manufacturing leaving the others to be programmed at the point-of-sale terminal 320.
At 406, a payment is conducted from the wireless device 104 to the point-of-sale terminal 320. At step 407, after the payment of step 406 has been completed, a service provider would activate the unique identifier. Alternatively, the communication interface 105 may be locked. Locking of the communication interface 105 may include encryption with wireless device 104 information and/or programming of an additional code into the communication interface 105 to generate a unique identifier for the wireless device 104 and/or selection. At 408, the identifier of step 407 may be transmitted to the wireless provider backend system 322.
At step 410 the unique identifier codes along with wireless device 104 information are received by the wireless provider backend system 322. At step 415, the wireless provider backend system 322 can verify the unique identification code by searching for the unique identification code in one or more databases to make sure the unique identification code has not been recorded/redeemed previously. At step 417, if the system finds the unique identification code is not approved, the activation of the wireless service will be stopped 418. Upon stopping the activation 418 of the wireless service, the wireless provider backend system 322 may send a warning message to the user 312 (e.g., using the wireless device 104) and/or the wireless provider. Alternatively at step 420, if when the unique identification code is approved (authentic, not been previously used, or the like), authorization of a wireless service, including payment verification, may take place. At 421, the authorized unique identification code is recorded in a database of the wireless provider before, after, or during, the activation, of step 425, of the wireless service on the wireless device 104 takes place. At step 426, the use of the wireless service activated may be monitored to determine when the corresponding wireless service has been expended by the user 312.
