一种小区切换方法及设备技术

本发明专利技术涉及移动通信技术领域，尤其涉及一种小区切换方法及设备，用以解决因向UE重发切换命令而造成资源浪费的技术问题；本发明专利技术实施例中，第一接入网设备在向终端设备发送切换命令后，可以检测终端设备是否向第二接入网设备发送前导序列，如果检测到终端设备已经向第二接入网设备发送了前导序列，则第一接入网设备可以确定终端设备已经接收到了切换命令，因此，第一接入网设备无需再向终端设备发送切换命令，避免切换命令的无效重发，节省传输资源。

A cell switching method and equipment

The invention relates to the field of mobile communication technology, in particular to a cell switching method and device to solve the technical problem of resource waste caused by the UE retransmission switch command; in the embodiment of the invention, the first access network device can detect whether the terminal device is connected to second after sending a switching command to the terminal device. If the network device sends a preamble sequence, if the terminal device has already sent a preamble sequence to the second access network device, the first access network device can determine that the terminal device has received the switching command. Therefore, the first access network device does not need to send a switching command to the terminal device to avoid the invalid weight of the switching command. Send, save the transmission resources.
