Abstract

A method, a system, and a device for establishing a service connection are provided. The method includes the following steps. An interface configuration parameter is obtained, in which the interface configuration parameter includes an interface configuration parameter of a remote device. An interface parameter object is added to a user network interface (UNI) request message, in which the interface parameter object carries the interface configuration parameter. The UNI request message carrying the interface configuration parameter of the remote device is sent to the remote device, so as to establish a service connection with the remote device. Thus, the interface parameter object is added to the UNI request message, and then the UNI request message carrying the interface configuration parameter of the remote device is sent to the remote device, for establishing the service connection, so as to realize automatic negotiation and configuration of the interface parameters, thereby saving manpower resources.
