“…In users' view, QoS [3] requirements, user preferences to access network coding schemes, user preferences to access network providers, user handover history record, costs user willing to pay and access network status are considered. From the perspective of network, the profit of suppliers [4] and other factors are considered to maximize the use of existing network resource and ensure the handover couldn't happen frequently to avoid the "PingPong Effect" [5]. Literature [6] presented a method based on RSS (received signal strength) vertical handover decision scheme.…”

To find an optimal handover solution of terminal users under heterogeneous wireless networks, Pareto optimum under Nash equilibrium of users' utility and network provider utility is achieved or approached for the found solution. QoS (quality of service) requirements, user preferences to access network coding schemes, user preferences to access network providers, user handoff history record, costs user willing to pay and the profit of suppliers are considered comprehensively in this paper. With introducing the knowledge of fuzzy mathematics and microeconomics, access networks and terminals are described. With the help of gaming analysis, an intelligent handover decision scheme with ABC (always best connected) supported is proposed by using coarse-grained and fine-grained crossover free search based intelligent optimization algorithm. After carrying out simulation and performance evaluation, the results show that the mechanism proposed in this paper is feasible and effective.Keywords-NGI (next generation Internet); QoS (quality of service); ABC (always best connected); handover decision; intelligent optimization algorithm; search based on coarsegrained and fine-grained crossover

In order to continue to provide high quality communication services, mobile network operators want to detect the degradation of the communication quality when it occurs. Since actively evaluating LTE network performance is costly and time consuming, mobile network operators passively monitor the network. A finite state machine is a powerful approach for monitoring the network condition. However, in actual LTE network, it is not sufficient to validate the conformance between the specification machine and the implementation machine. Therefore, this paper proposes a LTE network monitoring method using statistics of state transition. In the proposed method, we first define the states according to 3GPP standards, then, we measure the state transition by referring to LTE C-Plane messages. Also, we measure the state transition probability and time interval for the transition. Finally we check the statistics of the state transition to detect the degradation of the communication quality. In order to evaluate the proposed method, we introduce an example of detecting ping-pong handovers using actual traffic data. We show the potential usefulness of the proposed method for practical use.
