Abstract: PURPOSE: A method for setting a communication environment of a smart card and a mobile terminal which use a protocol stack of a hierarchical structure is provided to construct the optimized communication environment with respect to each application rapidly and stably in a multi-application smart card system. CONSTITUTION: If a smart card(100) is inserted into a mobile terminal(200), the mobile terminal(200) applies power to the smart card(100, S100). If a power is applied from the mobile terminal(200), the smart card(100) executes a reset operation in accordance with the applied power and transmits information with respect to a supportable communication environment to the mobile terminal(200) as a response signal thereto(S202). After analyzing a communication environment of the smart card(100), the mobile terminal(200) transmits a logic channel opening request message for opening a logic channel with the smart card(100) to the smart card(100, S203). The smart card(100) opens a logic channel with the mobile terminal(200) in accordance with the logic channel opening request message received from the mobile terminal(200) and transmits a response message with respect to the logic channel opening request to the mobile terminal(200, S204).

Abstract: PURPOSE: A method for managing and controlling an entitlement in a chargeable broadcasting system for supporting various pay-view services is provided to classify a series by setting a proper theme ID and an event ID when a qualification managing message is created. CONSTITUTION: A key ID(21) is used for a cryptography of a plurality of information(22, 23, 24, 25, 26). Mask information(22) is a value for deciding an application range of a theme ID(23) and an event ID(24). The mask information(22) is identified with the sum of sizes of two fields. EXTM information(25) indicating an expiration time is used for deleting a qualification record exceeding to the time from a memory by an interior operation of a smart card. DUR information(26) is valid only in the case of a PPP service. The information from the mask information(22) to the DUR information(26) means a watching right of each member. If the corresponding qualification is valid, the information is stored in a card memory. In the case of a PPE(pay-per-event), the total value of the theme ID(TID)(23) and an event ID(EID)(24) becomes a valid program ID. In the case of a PPS(pay-per-series), the DUR information(26) is ignored and a bit calculation logical value of the mask information(22) and the theme ID(TID)(23) become a series. In the case of a PPP(pay-per-period), a user can watch from a starting time of watching of a chargeable program to a time passed for the DUR, and if the smart card receives a qualification managing message, one's expiration time is changed into a time adding the current time to the DUR, and thus the corresponding service is possible.
Abstract translation: 目的：提供一种用于管理和控制用于支付各种付费视图服务的可收费广播系统中的授权的方法，用于通过在创建资格管理消息时设置适当的主题ID和事件ID来对一系列进行分类。 构成：密钥ID（21）用于多个信息的加密（22,23,24,25,26）。 掩模信息（22）是用于决定主题ID（23）和事件ID（24）的应用范围的值。 掩模信息（22）用两个字段的大小的和来标识。 指示过期时间的EXTM信息（25）用于通过智能卡的内部操作来删除超过存储器的时间的资格记录。 DUR信息（26）仅在PPP服务的情况下有效。 从掩模信息（22）到DUR信息（26）的信息是指每个成员的观看权。 如果相应的资格有效，则信息存储在卡存储器中。 在PPE（按付费方式）的情况下，主题ID（TID）（23）和事件ID（EID）（24）的总值变为有效的程序ID。 在PPS（按系统付费）的情况下，DUR信息（26）被忽略，并且掩码信息（22）和主题ID（TID）（23）的位计算逻辑值变为一系列。 在PPP（每期付费）的情况下，用户可以从观看可收费节目的开始时间观看到DUR所经过的时间，并且如果智能卡接收到资格管理消息，则到期时间 改变为将当前时间添加到DUR的时间，因此相应的服务是可能的。
