摘要：

随着LTE国际漫游业务的逐步开通，用户跨境漫游选网时延过长的问题日益受到关注。研究了基于对等PLMN的LTE国际漫游优化方案，并通过在深圳、香港两地边境口岸的深圳移动和香港移动LTE网络联合部署对等PLMN技术，实现终端在两个地区运营商之间的跨境空闲状态小区重选以及连接状态重定向，进而达到低成本快速提升用户漫游感知的目标。优化方案实施后，深圳、香港两地漫游用户过境时平均通信中断时长由原来的90 s大幅缩短至5.96 s，减少93.4%，极大地改善了两地用户往来漫游感知。

Abstract:

With the development of LTE international roaming, the long time delay for roaming network selection has recently attracted much attention. A LTE international roaming optimization scheme based on equivalent PLMN was investigated. By deploying the scheme in China Mobile Shenzhen Branch and HongKong Branch LTE networks at frontier ports area, UE can do reselection（in idle mode）and redirection（in connected mode）between cells from different operators across the boundary. The average no service time across the boundary shortened from 90 seconds to 5.96 seconds, the customer's international roaming perception was greatly improved.

Key words: LTE international roaming, equivalent PLMN, network selection
