    • A selective call device (130) has a receiver (204) for receiving a selective call signal including an address (312). An address correlator (214) coupled to a decoder (212) determines that the selective call signal is directed thereto and determines whether the selective call signal includes an update command (400, 500). The update command includes a major version number (406, 506), topic numbers associated with sub-message(s) stored in the selective call device, update data associated with each topic number for updating the sub-messages, and minor version numbers (427, 527) associated with each topic number. The major version number is incremented when a sub-message template is changed. Minor version numbers are incremented after each update. The selective call device updates a sub-message with update data only if the update command includes a current major version number and an incremented minor version number.
    • 选择呼叫装置(130)具有用于接收包括地址(312)的选呼信号的接收机(204)。 耦合到解码器(212)的地址相关器(214)确定选择呼叫信号被指向其并确定选呼信号是否包括更新命令(400,500)。 更新命令包括主要版本号(406,506),与选择性呼叫装置中存储的子消息相关联的主题号码,与用于更新子消息的每个主题号码相关联的更新数据和次要版本号( 427,527)与每个主题号码相关联。 当子消息模板被更改时,主版本号增加。 每次更新后,次版本号都会增加。 只有当更新命令包含当前的主版本号和递增的次版本号时,选呼设备才更新具有更新数据的子消息。
