Abstract
A communication system synchronizes subscriptions between a user terminal (UT) and a Subscription Service Host (SSH). The UT conveys, to the SSH, multiple subscription messages associated with a Watcher that each initiates a subscription associated with the Watcher and requests watched entity status information. The UT starts a timer and, in response to an expiration of the timer, conveys a subscription information consolidated status update (SICSU) request to the SSH that requests a consolidated status update of all subscriptions associated with the Watcher. In response, the UT receives an SICSU notification comprising a first one or more SICSU values that indicate a status of multiple subscriptions associated with the Watcher, determines a corresponding second one or more SICSU values based on its own list, compares the first SICSU values to the second SICSU values, and determines whether the UT is out of synchronization with the SSH based on the comparison.
