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 |
20090092254 | METHOD FOR EFFICIENTLY PROVIDING KEY IN A PORTABLE BROADCASTING SYSTEM AND SYSTEM USING THE SAME - A method for efficiently providing a key in a portable broadcasting system and a system using the same are provided, in which when a user selects a service to be purchased after invoking a broadcasting application, a terminal transmits a service request message including information about the selected service, a server transmits a service response message including a key required for using the selected service in the form of a MIKEY, and the terminal receives the service response message. | 04-09-2009 |
20090143105 | SMART CARD AND METHOD FOR GENERATING RESPONSE MESSAGE TO BE DELIVERED TO MOBILE TERMINAL SUPPORTING MOBILE BROADCAST, AND MOBILE TERMINAL THEREFOR - Provided is a method of efficiently processing a Short-Term Key Message (STKM) in the mobile broadcast supporting the mobile terminal. A structure of a response message according to processing the STKM in the smart card is also provided. In particular, a variety of information necessary for reproducing in the player is included in the response message and delivered to the mobile terminal, thereby the mobile terminal can easily obtain the desired information through the response message. Therefore, when the STKM is processed in the mobile terminal, there is no need to process operations except for a resending check, and the information does not need to be stored separately. | 06-04-2009 |
20090197523 | METHOD AND SYSTEM FOR PROVIDING PAID CONTENTS IN A PORTABLE BROADCASTING SERVICE - A method and system for providing paid service contents in a portable broadcasting service are provided, in which a first broadcasting-receiving terminal requests service purchase by indicating paid contents to be purchased and designating a service consumer to receive the paid contents, and a broadcasting server provides the paid contents to a second broadcasting-receiving terminal corresponding to the service consumer when the purchase of the paid contents is successful. | 08-06-2009 |
20090208021 | METHOD AND APPARATUS FOR MANAGING ENCRYPTION KEYS BY MOBILE COMMUNICATION TERMINAL CONNECTED WITH SMARTCARD - A method and an apparatus are provided for managing encryption keys by a mobile communication terminal connected to a smartcard that stores the encryption keys. The mobile communication terminal receives and stores encrypted multimedia data, extracts recording key information corresponding to an encryption key from the received multimedia data, determines whether the extracted recording key information has been previously stored in a recording key database, and maps the extracted recording key information to identification information of the received multimedia data and stores mapping data therebetween in the recording key database when the extracted recording key information has not been previously stored in the recording key database. | 08-20-2009 |
20090316911 | Apparatus and method for transmitting a plurality of key data - An apparatus and method for transmitting a plurality of key data. When a Short-Term Key Message (STKM) is received, a mobile equipment transmits the received STKM to a smart card. The smart card determines whether there are a plurality of key data in the STKM, detects the plurality of key data when there are the plurality of key data, generates individual information for identifying each of the plurality of detected key data, generates a response message having the plurality of detected key data and the generated individual information, and transmits the response message to the mobile equipment. Therefore, a plurality of key data can be included and transmitted in one message. | 12-24-2009 |
20100042509 | METHOD FOR PROVIDING BROADCAST SERVICE TO TERMINAL IN MOBILE BROADCAST SYSTEM AND THE MOBILE BROADCAST SYSTEM THEREFOR - Disclosed is a method for providing a broadcast service in a mobile broadcast system, and the mobile broadcast system thereof, in which a terminal receiving the broadcast service can check the purchase of the broadcast service, for which the terminal has made a purchase request in a web-based purchase scheme, or can check the purchase cancellation of the broadcast service in a web-based scheme. The mobile broadcast system includes: the terminal for receiving the broadcast service; and a broadcast server for adding a trigger type field to a smartcard trigger message including information on the broadcast service, transmitting the smartcard trigger message to the terminal when the terminal purchases the broadcast service from a content provider in the web-based purchase scheme, and guiding a registration process through a Short Message Service (SMS). | 02-18-2010 |
20100106648 | Method and apparatus for acquiring encryption key to provide pay channel - A mobile terminal is configured to acquire an encryption key to decrypt a pay channel encrypted with a smartcard profile by the mobile terminal in a Multimedia Broadcast/Multicast Service (MBMS) mobile broadcast system. The mobile terminal is configured to purchase a specific pay channel, determine validity of an encryption key, store a range of a valid encryption key identification value, and initialize a reference Time Stamp (TS) value. The mobile terminal also; extracts an encryption key identification value and a TS value from a last received Short Term Key Message (STKM), when a view request for the specific pay channel is created; and determines that an encryption key is valid, when the extracted TS value satisfies the reference TS and the extracted encryption key identification value falls within a range of the valid encryption key identification value, and extracts and acquires an encryption key from the STKM. | 04-29-2010 |
