Abstract

The invention discloses a communication method based on an MQTT topic subscription mechanism and an access gateway. The communication method comprises that an IMService, an MQTTClientI, an MQTTClientR, an MQTTServer of an access gateway A and a corresponding access gateway B are started, a first user comes online on the access gateway A, a second user comes online on the access gateway B, based on the access gateway A and the access gateway B, the first user exchanges messages with the second user. According to the invention, the problem existing in the prior art that a message router of a distributed instant messaging application is complex is solved, the complex message routing function can be omitted, messages can be forwarded based on the subscription relation maintained by the server and messages based on the subscription relation, and the message routing function can be automatically achieved, and therefore the message routing table does not need to be maintained, and the instant messaging scheme is simplified.

Description

technical field

[0001] The invention relates to the communication field, in particular to a communication method and an access gateway based on an MQTT topic subscription mechanism. Background technique

[0002] Instant messaging (IM for short) is a terminal service that allows two or more people to use the Internet to transmit text messages, files, voice and video in real time. Instant messaging can be divided into enterprise instant messaging and website instant messaging according to the purpose of use, and can be divided into mobile instant messaging and PC instant messaging according to the loading object. The representative of mobile instant messaging is SMS, and the representative of PC instant messaging is video.

[0003] MQTT (Message Queuing Telemetry Transport) is an instant messaging protocol developed by IBM, which may become an important part of the Internet of Things. The protocol supports all platforms and can connect almost all Internet-connected objects to...
