一种锚点网关的切换方法、装置及系统制造方法及图纸

本发明专利技术实施例提供一种锚点网关的切换方法、装置及系统，涉及通信技术领域，避免报文在迂回的转发路径中传输。该方法包括：CP设备确定切换源锚点网关；CP设备获取终端的位置信息；CP设备根据位置信息确定目标锚点网关；CP设备向SDN控制器发送修改请求消息，该修改请求消息包括该终端的标识和该目标锚点网关的标识，该修改请求消息用于指示SDN控制器根据该终端的标识和该目标锚点网关的标识更新与该下行报文对应的转发流表，并将更新后的该转发流表发送至SDN交换机，以使得SDN交换机根据该更新后的转发流表将该下行报文转发至该目标锚点网关，由该目标锚点网关为该终端转发该下行报文。该方法应用于锚点网关切换的场景中。

A Switching Method, Device and System of Anchor Gateway

The embodiment of the present invention provides a switching method, device and system of an anchor gateway, which relates to the field of communication technology and avoids the transmission of messages in a roundabout forwarding path. The method includes: the CP device determines the switching source anchor gateway; the CP device obtains the location information of the terminal; the CP device determines the target anchor gateway according to the location information; the CP device sends a modification request message to the SDN controller, which includes the identification of the terminal and the target anchor gateway, and the modification request message is used to instruct the SDN controller according to the identity of the terminal. The tag of the target anchor gateway updates the forwarding flow table corresponding to the downlink message, and sends the updated forwarding flow table to the SDN switch, so that the SDN switch forwards the downlink message to the target anchor gateway according to the updated forwarding flow table, and the target anchor gateway forwards the downlink message to the terminal. This method is applied to the scenario of anchor gateway handover.
