In this paper, we propose a new architecture for LTE/EPC network by leveraging the Openflow technology. We focus on making detail procedures for initial attach and default bearer setup in Openflow-enabled LTE/EPC network. By numerical analysis, we show the reduction of the signaling load of this procedure in our architecture compared to that in the traditional LTE/EPC architecture.
The current ever-growing advances in wireless networking and the great success of mobile computing have contributed to the development of an increasing amount of mobile services. Due to this growth of published services, quality of service (QoS) is becoming a key feature to provide the most appropriate needed service to mobile clients according to their requirements. However, managing QoS represents...
Mobile devices like PDAs or mobile phones have become widespread. Similarly network functionality like GSM, Bluetooth or WLAN has become a standard. Nevertheless, not many applications take mobility into account. An application and its communication component are tightly coupled and the application assumes that network behavior does not change. Here in this paper we propose a new lightweight architecture...
With the ubiquity of handheld devices people can now access information and conduct online transactions virtually anywhere and anytime. In such flexible but less reliable environment transaction management technology is believed to provide service reliability and data consistency. Existing models developed for mobile transactions mainly focus on variation of conventional commit procedures and give...
With the growing number of services made available, through next generation networks, it is important that end-users have easy access to the right services at the right time. This paper explores a way by which this may be achieved, namely, the recommendation of services to the end-user at an opportune time. Presented is an architecture for the recommendation of services. A possible deployment with...
