METHOD AND APPARATUS FOR SIGNALING UPDATES TO NOTIFICATION SESSION IN IP DATACAST

摘要

Systems and methods of signaling changes and updates associated with the default notification channels in a non-time sliced way are provided. A default notification channel event is signaled to a terminal. The signaling includes a reference to the relevant default notification channel, a timestamp, and/or a version number/counter. A comparison is made between a stored timestamp and/or version number/counter with the timestamp and/or version number/counter indicated in the signaling. A more recent timestamp and/or version number/counter prompts the terminal to tune in to the default notification channel to process the default notification channel event. The signaling can be performed using Program Specific Information/Service Information (PSI/SI), which is non-time-sliced and is received by all terminals. Additionally, the PSI/SI signaling is effectuated by creating descriptors in existing notification/network information tables and/or by creating a dedicated notification signaling table.
