| 中文摘要: |
| 针对现有标准中家庭基站(HeNB)重新启动后,可能存在的频率和物理小区标识(PCI)改变,从而影响终端(UE)向家庭基站切换的问题.提出了一种改进的HeNB切换解决方案,优化了切换测量过程,防止宏基站(MeNB)对终端进行错误的测量配置.通过仿真验证表明优化方案与已有方案相比,降低了测量时延,并提高了切换成功率. |
| 英文摘要: |
| According to current LTE specification,the HeNB will change its working frequency and physical cell id(PCI) after it restarts,and it reduces success rate of the inbound handover.This paper proposed an inbound handover solution which improves the handover measurement procedure and avoids improper measurement configuration from macro eNBs.Our simulation results show that the proposed solution reduced the measurement delay and improved the success rate of handover. |
