Rich Communication Services (RCS) is a messaging protocol designed to enhance traditional SMS/MMS by offering features such as rich media, read receipts, typing indicators, and, in some cases, end-to-end encryption. Developed under the GSMA's Universal Profile, RCS seeks to modernize mobile messaging and compete with popular services like WhatsApp and iMessage by enabling high-resolution media sharing, group chats, and business messaging with chatbots and rich cards. Unlike traditional SMS, RCS functions over IP networks, requiring carrier and device support, with Google's Jibe platform facilitating its use for carriers lacking infrastructure. While RCS provides a more interactive and secure messaging experience, it faces challenges such as limited support for iPhones, inconsistent carrier adoption, and varying availability of encryption. Despite these hurdles, RCS has the potential to become a standard for mobile communication, particularly as more carriers and businesses adopt it to leverage its advanced features for customer support, e-commerce, event invitations, and secure banking alerts.

Skill-based matchmaking (SBMM) is a foundational element in multiplayer gaming, designed to ensure players face opponents with similar skill levels, but PubNub explores extending this concept to create more personalized matchmaking systems.
