本文提出了一种基于环的综合无线光网络架构及其协议，该架构涉及以太网无源光网络（EPON）和长期演进（LTE）无线网络。该体系结构和所提出的协议有助于减少切换延迟。提出的基于环的EPON架构通过EPON回程光网络单元之间的直接通信，为LTE网络X2接口的实现提供了便利。该工作进一步讨论了开放接入网络架构，其中单个EPON可以由多个移动服务提供商使用，而不会影响信息安全。已经进行了大量的仿真来评估所提出的网络的性能。引入了一个解析模型来计算X2接口所经历的排队延迟。仿真结果验证了该模型的正确性。
This paper proposes a ring-based integrated wireless optical network architecture and an associated protocol that involves Ethernet passive optical network (EPON) and long term evolution (LTE) wireless network. The architecture along with the proposed protocol is instrumental toward the reduction of handover delay. The proposed ring-based EPON architecture facilitates the implementation of the X2 interface for LTE network by enabling the optical network units of the EPON backhaul to directly communicate with each other. The work further discusses about an open access network architecture where a single EPON can be used by multiple mobile service providers without compromising information security. Extensive simulations have been carried out to evaluate the performance of the proposed network. An analytical model has been introduced to calculate the queuing delay experienced by the X2 interface. The model has been validated with the simulations results.
