Specifically, the sending end may be a terminal device capable of supporting internet communication; the media data may include at least one of audio data, video data, and text data. Before the step S101, the communication method provided by the present application further includes: the connection between the sending end and the cloud file server is established in advance, for example, the connection between the sending end and the cloud file server can be established through a registration process.
In this embodiment, the specific implementation process of step S101 may be: and the sending end sends the media data to the cloud file server through an HTTP (hyper text transport protocol). The HTTP protocol is a hypertext transfer protocol, can transfer various types of media data, and is a protocol mode widely used. The method for sending the media data between the sending end and the cloud file server through the HTTP is mature and stable. After receiving the media data, the cloud file server may store the media data in a corresponding area; for example, the cloud file server may set different storage areas for each sending end, and after receiving the media data, the cloud file server stores the media data into the storage area of the sending end corresponding to the media data. And then the cloud file server can generate a corresponding storage address and feed the storage address back to the sending end through an HTTP (hyper text transport protocol).
S102: the sending end pushes a new message notification to the MQTT server through an MQTT protocol, the new message notification comprises a topic subscribed by the sending end and a storage address, and therefore at least one receiving end subscribed to the same topic downloads media data from the cloud file server through the storage address.
Specifically, the Chinese language of the MQTT protocol is a message queue telemetry transmission protocol, is a 'lightweight' communication protocol based on a publish/subscribe mode, and has the advantages of short and short, long link, low system overhead and the like, so that the application range is wide. The method for pushing the new message notification through the MQTT protocol can reduce the system overhead and improve the response efficiency of the system.
In addition, when step S102 is performed, when the sending end receives the fed-back storage address, it indicates that the media data sent by the sending end has been successfully stored in the cloud file server, and at this time, the sending end may push a new message to notify the MQTT server. And because the new message notification comprises the topic and the storage address subscribed by the sending end, the MQTT server can push the new message notification to the receiving end subscribed with the same topic as the current sending end according to the topic in the new message notification, and after the receiving end receives the new message notification, the receiving end can go to the cloud end file server according to the storage address in the new message notification and download the media data, thereby reducing the hardware requirement of the system on the MQTT server.
On one hand, in the application, a sending end and a receiving end in the network interphone want to join/leave a certain channel, and can subscribe/cancel a certain theme through an MQTT protocol, so that the operation is simple and convenient, and equipment ends in the same channel can receive media data published in the channel; on the other hand, the network interphone in the application is not influenced by communication distance, building shielding signals and the like unlike the traditional interphone, and the network interphone expands the interphone function by virtue of the advantages of the mobile internet; on the other hand, in the process of sending the media data by the sending end in the application, the media data are stored in the cloud file server and cannot be directly sent to the MQTT server, and the mode can reduce the hardware cost of the MQTT server, so that the MQTT server with weak processing capacity can also realize the function of the network interphone.
In one embodiment, before step S102, the method further includes: the transmitting end registers through an MQTT protocol to establish connection with an MQTT server. The registration is a process that a user does not sense, and after the registration is carried out, the sending end can keep long link with the MQTT server, so that the real-time performance of signaling control is ensured. When the sending end establishes connection with the MQTT server for the first time, the registration process and the activation process can be carried out.
In another embodiment, there may be only one sender subscribing to the current topic, at this time, in order to remind the sender, after the step S102, the communication method provided by the present application further includes: the sending end judges whether a new message notification or a non-forwarding notification sent by the MQTT server is received or not; if yes, the fact that no receiving end which has the same theme with the sending end subscribes currently is indicated.
Of course, in other embodiments, the sender may be reminded in other manners. For example, before the sending end sends the media data to the cloud file server in step S101, the communication method provided by the present application further includes: temporarily storing the collected media data in a storage area of a sending end; the method comprises the steps that a sending end sends an inquiry instruction to an MQTT server through an MQTT protocol, wherein the inquiry instruction comprises the number of terminals subscribing the same theme as the sending end; the sending end receives a feedback result which is sent by the MQTT server and corresponds to the inquiry instruction; if the number of the terminals subscribing the current theme is 1, the current theme is subscribed by only one terminal of the sending end, and a prompt can be sent to enable a user of the sending end to know the current theme at the moment, wherein the prompt can be a voice prompt or a flashing light prompt; if the number of the terminals subscribing to the current theme exceeds 1 in the feedback result, it indicates that other receiving terminals subscribe to the theme currently, and at this time, step S101 may be entered, and the sending terminal may directly send the media data to the cloud file server.
The communication method of the network interphone is further explained from the perspective of the receiving end. Referring to fig. 2, fig. 2 is a schematic flow chart illustrating an embodiment of a network interphone communication method of the present application.
The communication method comprises the following steps:
s201: and the receiving end receives a new message notification which is sent by the MQTT server and is related to the subscribed theme, wherein the new message notification comprises the theme and a storage address of the media data which is sent by the sending end and stored in the cloud file server.
Specifically, the receiving end may be a terminal device capable of supporting internet communications; the receiving end can receive a new message notice which is sent by the MQTT server and is related to the subscribed topic through the MQTT protocol.
S202: and the receiving terminal downloads the media data from the cloud file server through the storage address.
Specifically, in this embodiment, the receiving end may download the media data from the cloud file server through the HTTP protocol and the storage address. The method for downloading the media data between the receiving end and the cloud file server through the HTTP is mature and stable.
