碩士 === 元智大學 === 資訊工程學系 === 102 === 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, in view of these, we propose an integrated architecture to converge GPON and LTE including a hierarchical Dynamic Bandwidth Assignment (DBA) with Admission Control (AC) to solve heterogeneous traffic in integrated network in this paper. First, we combine the ONU with evolve node B into an ONU-eNB device and briefly describe each function module. Second, a delay-based admission control scheme is proposed to guarantee the predesign QoS for each admit request in order to prevent drop. Third, we also propose two steps hierarchical DBA that first layer optical line terminal (OLT) allocate the bandwidth at DBA with past ten cycles and the second layer bandwidth reassignment will execute follow by service level agreement (SLA) in ONU-eNB to meet the predesign QoS for every user request to achieve integrated network.
