Abstract: The present invention provides a method for associating a user with a base station based on backhaul capacity in heterogeneous cellular network. First, an available base station set is obtained through the SINRs, and the downlink data rate between the new user and each base station in the available base station set is calculated according to the SINR between them; Then, the usable link capacity factor of each base station is calculated based on the used link capacity and the backhaul capacity; Finally, the optimal base station is selected for the new user i under a constraint which is constructed by the bandwidth of the new user and the usable link capacity factor. The backhaul capacity of each base station is taken into account in selecting the optimal base station to associate with for the new user, thus the real time of user association and the overall performance of heterogeneous cellular network can be guaranteed.

Abstract: The present invention provides a method for accessing internet via a vehicle network. Vehicle terminal equipment can access OBU by means of the wireless AP on OBU, and realize the mutual communication with internet with the help of VANET network composed by OBU and RSU. Not only the normal communication between the OBU and RSU is guaranteed, but also the communication between vehicle terminal equipment and internet can be realized. Moreover, the present invention has the characteristics of anti-interference, convenience and real-time performance, and can adapt to the demand of the current network.
