RCS Messaging Services
Course Details
This course seeks to provide a baseline level of knowledge for individuals seeking an end to end understanding of RCS messaging services. The course begins with a consideration of the capabilities, architecture and implementation of today’s RCS networks, including both on premise and cloud based deployment models. Next, initial procedures for RCS are covered, including first time provisioning, client provisioning, authentication, IMS registration and user capability discovery. The course then focuses specifically on messaging, outlining the different messaging options available, including group chat. Finally, the course concludes with a consideration of the different techniques available to enhance messaging, such as file transfer and geolocation, as well as messaging related services such as Enriched Calling and chatbots.
