摘要

移动数据的爆炸性增长带来了基站负载过大等问题

再加上频谱资源的稀缺

传统的蜂窝网络已经不能满足需求

为了获得吞吐量和用户密度的提升

异构蜂窝组网成为LTE-A（改进的长期演进）的必然选择。文章在假设SeNB（小基站）同时在S-MeNB（源宏基站）和T-MeNB（目标宏基站）的覆盖范围内的基础上

基于异构网中的双连接技术

对S-MeNB切换到TMeNB的流程进行了设计。为了验证此双连接切换流程设计的成功与否

文章提出了一种结合TTCN-3的实现方案

通过仿真图验证了流程设计的合理性和可行性。

Abstract

The explosive growth of mobile data brings the problems such as base station overload

the scarcity of spectrum resources and so on.The traditional cellular network can not satisfy the requirement.In order to obtain the throughput and user density enhancement

heterogeneous cellular network become the inevitable choice.In this paper

we assume that SeNB is based on the coverage of S-MeNB and T-MeNB simultaneously

and based on the dual-connection technology in heterogeneous network.Then we design the process of S-MeNB switching to T-MeNB.In order to verify the success of the design of the dual connection handover process

we present a scheme of combining TTCN-3

which verifies the rationality and feasibility of the process design.
