Gigabit Passive Optical Network (GPON) and Long Term Evolution (LTE) are two promising broadband access technologies for next-generation fiber-wireless network. With the advantage of their complementary features can be used to make up each other's drawbacks, optical part can unrestricted from the geography and wireless part can have higher transfer rate, they propose an integrated architecture to converge GPON and LTE. Based on this architecture, a hierarchical dynamic bandwidth assignment with admission control is proposed to well transmit heterogeneous traffic in this paper. First, they combine the ONU with evolve node B into a device and briefly describe each function module. Second, a dynamic delay-based admission control scheme is proposed to guarantee the required for each request to maximize the throughput.
