With the rapid development of mobile computing technologies, a new style of learning, termed as ―mobile learning‖, has exploded everywhere in the world. This is now considered as an essential learning style in the future. This paper presents the framework of a contextual mobile learning system taking into account the learning environment at Saudi Arabian universities. With the help of this system, the students can learn just in time in their daily lives whenever they need to learn; using mobile computing devices like Tablet PCs and Smart Phones. The main principles and the essential components such as functional modules and context databases are presented. The mobile learning framework has been validated by an interview based qualitative method.
