Title
(EN) Routing domain selecting method, device and system
(ZH) 路由域选择方法、装置和系统
Abstract
(EN) An embodiment of the invention provides a routing domain selecting method, device and system. The routing domain selecting method includes that a source node sends a first public land mobile network identity (PLMN ID) to a destination node, and the first PLMN ID is any one of identical PLMN IDs in the source node and the destination node; if the destination node accepts the first PLMN ID, the source node receives a reply message sent by the destination node; the source node sends a communication interface establishment request message to the destination node through a routing domain corresponding to the first PLMN ID. The routing domain selecting method, device and system is used for establishing network connection between the communication nodes by a correct routing domain.
(ZH) 本发明实施例提供一种路由域选择方法、装置和系统,一种路由域选择方法包括:源节点将第一通用陆地移动网络标识PLMN ID发送给目的节点,所述第一PLMN ID为任意一个所述源节点与所述目的节点中相同的PLMNID;若所述目的节点接受所述第一PLMN ID,则所述源节点接收所述目的节点发送的回复消息;所述源节点通过所述第一PLMN ID对应的路由域,向所述目的节点发送通信接口建立请求消息。本发明实施例提供的路由域选择方法、装置和系统,用于在通信节点之间使用正确的路由域建立网络连接。
