Method, system and architecture for validating media sessions in networks that use communication protocols with distinct signaling and media channels

摘要

Methods for use in operation with a signaling path between given entities are disclosed. One such method includes: deriving, from signaling messages between the given entities, a negotiated set of attributes of an expected media session between the given entities; inferring, from the signaling messages and from semantics of another protocol underlying a session initial protocol, an inferred set of one or more non-negotiated attributes of the expected media session; during an actual media session negotiated by the given entities, determining whether the negotiated set and the inferred set of one or more non-negotiated attributes correspond to given attributes of the actual media session; and taking an administratively-defined action if the negotiated set and the inferred set of one or more non-negotiated attributes do not correspond to given attributes of the actual media session.
