Signaling systems are essential frameworks used in telecommunications to manage and control the flow of information between devices. They facilitate the establishment, maintenance, and termination of communication sessions, ensuring that data is transmitted efficiently and accurately. Common examples include SS7 and SIP, which are used in traditional and modern telephony, respectively. These systems not only handle voice calls but also support various services such as text messaging and multimedia sharing. By utilizing signaling protocols, networks can optimize resource usage and enhance user experience, making them a critical component of modern communication infrastructure.
