SYSTEMS, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR DISTRIBUTING APPLICATION OR HIGHER LAYER COMMUNICATIONS NETWORK SIGNALING ENTITY OPERATIONAL STATUS INFORMATION AMONG SESSION INITIATION PROTOCOL (SIP) ENTITIES

摘要

Systems, methods, and computer program products for distributing application or higher layer communications network signaling entity operational status information among SIP entities are disclosed. According to one aspect, a method includes determining operational status information for an application or higher layer communications network signaling entity. Further, the method includes identifying at least one second SIP entity to receive the operational status information. The method also includes distributing the operational status information to the at least one second SIP entity. The first SIP entity, the at least one second SIP entity, and the application or higher layer communications network signaling entity are associated with network nodes separate from subscriber communication terminals.
