Problems solved by technology

[0011] 1. In order to support two-way intercommunication, the soap interface is inconsistent with the http request and response, which makes the protocol implementation complicated and difficult to understand
[0012] 2. Found the shortcomings of TR069 in the transport layer, it is difficult to traverse NAT, and the signaling transmission is slow
[0013] 3. The message is bloated

Embodiment Construction

[0064] MQTT is a lightweight agent-based publish / subscribe message transmission protocol, designed to be open, simple, lightweight, and easy to implement. Provide one-to-many message publishing, decoupling applications, and message transmission for load shielding. Using TCP / IP to provide network connection, NAT traversal, real-time signaling sending and receiving can be maintained as long as a small overhead is used.

[0065] There are three identities in the MQTT protocol: Publisher, Broker (Server), and Subscriber. Among them, both the publisher and the subscriber of the message are clients, the message broker is the server, and the message publish can be a subscriber at the same time.

[0066] The message transmitted by MQTT is divided into two parts: topic (Topic) and load (payload).

[0067] Topic, which can be understood as the type of message, after the subscriber subscribes (Subscribe), it will receive the message content (payload) of the topic

[0068] payload, whi...

Abstract

The invention discloses a remote terminal management method based on an MQTT protocol. The MQTT protocol is used for replacing an http protocol, authentication based on the MQTT protocol is used for authentication, a load of the MQTT is used for sending a soap message, and a topic subscription mechanism is used for a sent receiving object. The MQTT protocol provides TCP long connection, and subsequent TR069 protocol signaling can be transmitted through the MQTT protocol. According to the invention, the TR069 message reliability is improved; the rapidity of the TR069 message is improved, and real-time message transmission can be realized through long connection of the MQTT; the timeliness and availability of management equipment are improved, and real-time operation can be performed on equipment management and updating; travel069 is supported to pass through nat, and other devices for passing through a tunnel and the like are not needed for support; based on the MQTT protocol, the TR069 protocol is easier to understand and implement.

Description

technical field [0001] The present invention relates to the technical field of remote terminal management, in particular to a remote terminal management method based on the MQTT transmission protocol, especially a TR069 protocol remote terminal management method. Background technique [0002] The full name of TR069 is "Customer Terminal Equipment Wide Area Network Management Protocol (CWMP)", which is suitable for remote terminal management technology. The document number used to carry this protocol is TR069, referred to as TR069 protocol. It can flexibly and conveniently manage a large number of IP terminal equipment such as VoIP and IPTV. The connection model is flexible, allowing both the management side and the terminal to initiate connection requests; it has rich functions, software upgrades, and business push, and adopts the Server / Client (Agent) mode. The current basic sub-model of TR069 is shown in Table 1 below. [0003] Table 1 The existing basic sub-models of TR...
