"Samsung IMS" refers to Samsung's implementation of the IP Multimedia Subsystem (IMS) on its devices. IMS is a core architectural framework used in modern mobile networks to deliver advanced communication services over an IP (Internet Protocol) network. In simple terms, IMS is the technology that allows your phone to make calls, send messages, and use other multimedia services over a 4G or 5G data connection, rather than relying on older 2G or 3G networks. Key functions and features of Samsung's IMS implementation include: * VoLTE (Voice over LTE): This allows you to make high-quality voice calls using your 4G data connection. Without IMS, your phone would have to drop to a 2G or 3G network to make a traditional phone call, which can result in lower audio quality and slower connection times. * VoWiFi (Voice over Wi-Fi): This enables you to make and receive calls over a Wi-Fi network, which is especially useful in areas with poor cellular reception. * RCS (Rich Communication Services): This is the next generation of SMS and MMS. RCS messaging, often seen in apps like Google Messages, allows for features like read receipts, typing indicators, and sharing high-resolution photos and videos. * SMS over IMS: This allows text messages to be sent and received over the IMS framework, improving reliability and delivery speed. Samsung's IMS is a crucial component of its phones' network infrastructure, ensuring smooth, reliable, and high-quality communication. It's a fundamental part of the Android system, and its functionality is closely tied to the carrier's network to enable these advanced services.
