在第三代合作伙伴计划(3GPP)提出的面向第五代移动通信技术的多网融合中，加强的长期演进(LTE-A)与无线局域网(WLAN)的交互融合对系统的吞吐量和传输速率有很大提升，蜂窝局域网聚合(LWA)的引入为实现多网融合进行资源的集中管理和控制提供了架构的设计基础。文章基于LTE-A升级系统的无线资源管理功能和丰富的频谱资源，设计了LTE-A与WLAN的链路聚合，实现了LWA无线承载的建立和切换功能；基于测试与测试控制描述第三版(TTCN-3)语言的终端无线资源管理一致性测试平台对流程设计进行了验证，证明了该设计的可行性。

In the multi-network convergence of 5G proposed by 3GPP, the convergence of Long Term Evolution-Advanced (LTE-A) and Wireless Local Area Network (WLAN) has greatly improved the throughput and transmission rate of the system. The introduction of LTE-A WLAN Aggregation (LWA) is the centralized management of resources for multi-network integration and control, which is regarded as the basis of the architecture. Based on the radio resource management function and WLAN spectrum resources of LTE-A Pro system, the link aggregation of LTE-A and WLAN is designed to realize the establishment and switching functions in the LWA radio bearer. Finally, the terminal wireless resource management conformance test platform based on Test and Test Control Description Third Edition (TTCN-3) language is used to verify the design of the process, which proves the feasibility of the design.
