The gateway device for generally serving home broadband access is called client device or BUCPE for short. BUCPE in the present invention refers to ONU. The BUCPE can obtain the geographical position information by a mobile phone which is provided with a special application program for broadband universal service, and can also send the geographical position information to the BUCPE which is upstream of the PON by the OLT. The BUCPE then communicates with the management support platform via a D1 interface. The D1 interface is a communication interface between the reporting agent function module in the client device and the universal service management support platform. All sessions of the D1 interface are initiated by a reporting agent module in the client. Each session includes one or more request and response interactions. The request and response are both encapsulated in JSON-format messages and transported over the HTTP/1.1 protocol (see IETF RFC 2616).
In the traditional implementation requirements, only basic functions such as basic information reporting, position information reporting, download rate testing, network connectivity testing and the like are defined, and an upgrading function is not defined. Maintenance loss is brought to maintenance personnel applying the platform, and the maintenance personnel need to find other platforms or modes to carry out upgrading maintenance work on the ONU, so that great inconvenience is brought to the maintenance personnel.
