Admission control strategy in LTE-A and WLAN integrated network

With the rising of smart devices and data-intensive service, more and more people have been dedicated to the study of a novel network architecture and communication solution. As 5G revolutionizes how humans acquire, manage and engage with information, this trend will accelerate. To meet this evolution, a novel admission control strategy in LTE-A and WLAN integrated network is proposed in this paper. In the coexistence scenario of macro base stations and pico base stations, the pico base stations could use LTE-A or WLAN. In the proposed strategy, part of the users in the extension range of the pico cell are selected to redistribute the served base station and served access network. This admission control strategy could keep LTE-A network and WLAN network balanced and not crowded. We investigate the performance of this strategy for different scenarios. The simulation results shed light on that the admission control strategy really has a good effect on the improvement of the system performance.
