越区切换作为GSM-R系统中的基本技术,是保证GSM-R网络服务质量的重要指标,设计不妥会造成掉话。因此,越区切换是网络运行考核的重要指标,是网络设计、优化的重点内容。简要介绍了GSM-R网络越区切换的原因,利用优化工具分析越区切换原因。
As the basic technology in GSM-R system, handoff is an important indicator to ensure the service quality of GSM-R network. Improper design will cause dropped calls. Therefore, the handover is an important indicator of network operation evaluation, network design, optimization of the key elements. The reason of GSM-R network handover is briefly introduced, and the reason of handover is analyzed by optimization tools.
