【摘要】：長(zhǎng)期演進(jìn)(LTE)網(wǎng)絡(luò)是3GPP定義的先進(jìn)移動(dòng)網(wǎng)絡(luò)系統(tǒng),相比現(xiàn)有的2G和3G網(wǎng)絡(luò),LTE網(wǎng)絡(luò)的用戶(UE)更加密集、站間距更小、更多的小基站加入系統(tǒng),從而使UE移動(dòng)性管理面臨更大的挑戰(zhàn)。為此,提出了一種新型UE切換方法。仿真結(jié)果顯示,新方法能夠很好地解決密集LTE異構(gòu)網(wǎng)絡(luò)中UE切換失敗率高的問(wèn)題,性能優(yōu)化顯著。
[Abstract]:The long-evolving (LTE) network is an advanced mobile network system defined by 3GPP. Compared with the existing 2G and 3G networks, the user (UE) of LTE network is more dense, the distance between stations is smaller, and more small base stations join the system. Thus, UE mobility management is faced with greater challenges. Therefore, a new UE switching method is proposed. Simulation results show that the new method can solve the problem of high UE handoff failure rate in dense LTE heterogeneous networks, and the performance optimization is significant.
