Embodiment 1

[0044] This embodiment provides an access gateway, figure 1 is a structural block diagram of an access gateway according to an embodiment of the present invention, such as figure 1 As shown, the access gateway includes: IMService (business processing module), MQTTClientI (internal client), MQTTClientR (external client) and MQTTServer (server), wherein,

[0045] IMService is the business processing module of the IM access gateway, responsible for the core business scheduling of the IM access gateway, including functions: user relationship management, access gateway and MQTTClientR mapping management, MQTTClientI and MQTTClientR calls, etc.

[0046] Its function is: used to register event notification with MQTTClientI, so that when the MQTTClientI receives the message from the MQTTServer, it will notify the IMService; it is also used to make the MQTTClientI subscribe to the topic of the MQTTServer; it is also used to create an MQTTClientR , so that the MQTTClientR is connected ...

Embodiment 2

[0054] This embodiment provides a communication method based on the MQTT topic subscription mechanism, figure 2 It is a flowchart of a communication method based on an MQTT topic subscription mechanism according to an embodiment of the present invention, such as figure 2 As shown, the method includes:

[0055] Step S202, start the IMService, MQTTClientI, MQTTClientR, and MQTTServer in the access gateway A and the corresponding access gateway B; wherein, MQTTClientI subscribes to the topic with the MQTTServer of the same access gateway, MQTTClientR connects with the MQTTServer of the corresponding access gateway, and subscribe topic;

[0056] Step S204, the first user goes online at access gateway A, and the second user goes online at access gateway B;

[0057] Step S206, based on the access gateway A and the access gateway B, the first user exchanges messages with the second user.

[0058] Through the above method, the complicated message routing function can be omitted, ...

Embodiment 3

[0076] image 3 is a schematic diagram of an access gateway startup process according to an embodiment of the present invention, as shown in image 3 As shown, the following steps need to be performed to start the access gateway (take the start of access gateway A as an example):

[0077] 1. The IMService that accesses gateway A registers event notifications with MQTTClientI, that is, when MQTTClientI receives a message from MQTTServer, it will notify IMService in the form of an event callback function.

[0078] 2. The IMService of access gateway A invokes the function interface of MQTTClientI to make MQTTClientI subscribe to the MQTTServer topic. The topic message includes: the message (Topic : IM / Push / AG / *, IM / Rpt / User / {UserID} / *).

[0079] 3. The IMService of access gateway A is based on the preset access gateway list (assuming that the scale of the access gateway is fixed, each access gateway will be configured with a list of all access gateways, and the list of access g...

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...
