Abstract: Embodiments of the present invention provide a handover method performed by a source access network device, which includes: sending, a handover request or a WLAN offload request to a UE, so that the UE determines information about a target AP according to AP information corresponding to a target RAN and information about a currently accessed AP, and sends a WLAN offload binding request carrying the information about the target AP to a target access network device in the target RAN, so as to complete a RAN handover, where the handover request or the WLAN offload request includes the AP information corresponding to the target RAN, and the AP information corresponding to the target RAN is information about an AP in a WLAN that covers, together with the target RAN, a location of the UE; and receiving a handover response or a WLAN offload response returned by the UE.

Abstract translation: 本发明的实施例提供一种由源接入网络设备执行的切换方法，包括：向UE发送切换请求或WLAN卸载请求，使得UE根据对应于AP的AP信息来确定关于目标AP的信息 目标RAN和关于当前访问的AP的信息，并将携带关于目标AP的信息的WLAN卸载绑定请求发送到目标RAN中的目标接入网络设备，以完成RAN切换，其中切换请求或 WLAN卸载请求包括对应于目标RAN的AP信息，并且与目标RAN相对应的AP信息是关于WLAN中的AP的信息，其与目标RAN一起覆盖UE的位置; 以及接收由UE返回的切换响应或WLAN卸载响应。

Abstract: A wireless communication method and a wireless terminal. A wireless terminal supports a first radio access technology (RAT) and a second RAT. The wireless terminal establishes a connection with a second RAT network. The wireless terminal receives a first message sent by the second RAT network. The first message includes content used to query a first RAT capability of the wireless terminal. The wireless terminal sends a second message to the second RAT network. The second message is used to indicate that the wireless terminal does not support the first RAT.
