20090030809 | MESSAGE CONFIGURING METHOD FOR CONTROLLING PURCHASE SERVICE IN WIRELESS BROADCASTING - Disclosed is a method for configuring a message for controlling purchase service in wireless broadcasting. When a portable terminal directly uses a corresponding service through registration without a process for purchasing a charged broadcasting service, the portable terminal directly receives a Multimedia Broadcast Multicast Service (MBMS) User ServiceID, and it is impossible to separate a GlobalPurchaseItemID and a PurchaseDataID from each other. Therefore, a purchase service list can not be known. However, according to the method herein, it is possible to separate two identifiers from each other in the portable terminal, so that it is possible to conveniently control each list regarding various types of purchased services. | 01-29-2009 |
