Quality Assurance Management for LTE Networks
Rapid developments in wireless communication technology have and continue to drive mobile communication services into ever evolving next generation mobile communication networks.  In this context, the proposed three-year project will develop a quality of service (QoS) mechanism and resource management between the IP Multimedia Subsystem (IMS) and Long Term Evolution (LTE).  This project, in tandem with other sub-projects, will determine an optimal algorithm to compute QoS, using real-time adaptive QoS parameters and dynamic management, for next-generation mobile communication networks. A Quality Assurance Management (QAM) Policy module will be integrated to manage user access permission functions. The QAM Policy module is based on IP Multimedia Subsystem (IMS) international standards, and it includes Codec Policy function, QoS Class Policy function, Application Class Policy function and Domain Policy function. Then, the project will enhance the network to meet LTE Release 10 standards. Combining the LTE network with an IP Network, will allow QoS agents to be placed in the Policy charging and rules function (PCRF) and the Evolved Packet Core, (EPC) function of the network. This sub-project is to be integrated with other sub-projects to realize the results of 4G-IMS testbed research. This research considers technology standardization, renewal and punctuality. Forehead technologies from other research centers can also be integrated using Cross-Layer, Cognition and Cooperation design structure to integrate original wire and wireless network structures in order to develop their practical and complete functions. Probable problems and solutions examined in this study may provide an important reference for building and operating actual 4G-IMS Networks in the future. The agents will exchange QoS information through NetFPGA platforms to ensure service quality of data transmission through control policy construction. The NetFPGA platforms will carry out this function by analyzing network traffic flow and using OpenFlow technology to control the flow. QoS information will form the control policy and exchange using a NetFPGA OpenFlow tunneling method named Capsulator.  Finally, the project will integrate a QAM Resource Management module into the previous LTE Release 10 standards-based network. One function of the module will be a QAM Charging System for users. The second function will be, a QAM Policy, module pool the users’ database and passes QoS information to the corresponding entities in the other sub-projects.
