Reduction of signaling on cellular systems with mobile agents: the POP3 application

Current cellular systems suffer already from signaling that uses the air interface resource. For example, in GSM systems, half of the available resources is dedicated for common and dedicated signaling. For future generations, systems will propose more services with QoS requirements. This increases the quantity of control information on the radio interface. In this paper, we propose a mobile agent based framework in order to reduce the number of signaling requests between the terminal and its base station. A POP3 application was used to illustrate the performance of the framework.
