Abstract
Methods, systems, and computer readable media system for collecting and distributing session initiation protocol (SIP) event watcher entity subscription information in a communications network are disclosed. According to one aspect, the method includes receiving, at a first notifier server from a watcher entity client, a first subscription request for SIP event information associated with one or more watched entity clients. The method also includes receiving, at a watcher information (WINFO) entity, SIP event subscription information that includes an identifier indicating that the first notifier server serves the watcher entity client, storing the SIP event subscription information in the WINFO entity, detecting the unavailability of the first notifier server. The method further includes sending an instruction message, based on the identifier in the stored SIP event subscription information, to direct the watcher entity to generate a second subscription request associated for the SIP event information.
