SYSTEMS AND METHODS FOR DISTRIBUTING AND REDEEMING CREDITS ON A BROADCAST SYSTEM |
摘要 |
Methods and systems enable receiving on mobile devices credits, tokens or coupons from mobile TV broadcast service providers. Credits may be delivered via direct unicast messages such as SMS or e-mail, or via broadcast provisioning messages. Subscription response messages may be used to deliver credits to mobile devises which transmit a request for service. Broadcast service providers may push credits to mobile devices by transmitting a solicited pull message or a credit grant push message. Credits may be sent to mobile devices within a credit response message or a long term decryption key message. Credits may be used a purchase transaction, with the broadcast service provider controlling redemption of credits by sending an a long term decryption key message via a unicast network or a short term decryption key message via the broadcast network to cause mobile devices to decrement their stored credits. |
