Signaling transmission method, device and system

The invention discloses a signaling transmission method, device and system, and belongs to the technical field of communication. The method comprises the following steps: a server receives a first signaling sent by a first device through m first transmission paths between the server and the first device, and sends the first signaling to a second device through n second transmission paths between the server and the second device. Wherein at least one of m and n is greater than 1, and the first signaling is used for establishing service connection between the first device and the second device. According to the application, the reliability of signaling transmission is improved, so that the success rate of establishing service connection is improved. 一种信令传输方法、装置及系统，属于通信技术领域。该方法包括：服务器通过该服务器与第一设备之间的m条第一传输路径接收第一设备发送的第一信令，并通过该服务器与第二设备之间的n条第二传输路径向第二设备发送该第一信令。其中，m和n中的至少一个大于1，第一信令为用于建立第一设备与第二设备之间的业务连接的信令。本申请有助于提高信令传输的可靠性，从而提高建立业务连接的成功率。
