Time sensitive messaging.

摘要

Time sensitive messages are sent from a sending station device (4) to a receiving station device (6). The messages are sent during calling party defined send windows. The messages include read windows that restrict the called party's access to the message after delivery to the receiving station. If a message is not delivered during the send window, or if a message is not read during the read window, the calling party may specify that an alternate message should be delivered. <IMAGE>
