Mobile learning (M-learning) is getting famous as a method of giving learners study materials at anytime and anywhere. In providing "at anytime and anywhere" way of study, there are various architectures and Unified Modeling Languages (UML) models that have been introduced by the developers. This paper presents a study of the architectures and the UML models that are designed by the developers for m-learning applications. Other than that, this paper also proposes suitable architecture and UML models of m-learning application for course content. Several literatures studies have been done in order to get information regarding the architectures and UML models those have been used, and based on the studies, a suitable architecture and UML models for m-learning for course content was proposed. © 2010 IEEE.
