What is an information push service?

Question 1: What is the meaning of information push service and what are the benefits of accepting information push service? In other words, if you close the application, the mobile phone will still receive the information sent by this application.

Question 2: What is the mobile phone push service? Operators, or mobile phone manufacturers, or third-party software send messages to designated users through servers!

Question 3: What does message push mean? A simple example:

Tencent QQ and WeChat server regularly push messages to their users. For example, Tencent information (news) and so on. When a user logs on to a client and accesses the network. You can receive messages pushed by it.

Official explanation:

The so-called information push is web broadcasting, which is a new technology that regularly transmits the information needed by users on the Internet through certain technical standards or protocols to reduce information overload. Through the automatic transmission propulsion technology

Information to reduce the search time on the network. It searches and filters information according to users' interests, and pushes it to users on a regular basis to help users efficiently explore valuable information.

Question 4: What is an information push service? Information push, namely web broadcasting, is a new technology that regularly transmits information needed by users on the Internet through certain technical standards or protocols to reduce information overload. The basic idea of push technology is to turn the browser's active query information into the server's active sending information. By automatically sending information to users, the search time on the network is reduced. It searches and filters information according to users' interests, and pushes it to users, helping users to explore valuable information efficiently.

Question 5: What does message push mean? In fact, it means sending to.

The so-called information push is a new technology to reduce information overload by sending the information that users need regularly on the Internet. Push technology reduces the time of searching on the network by automatically transmitting information to users. It searches and filters information according to users' interests, and pushes it to users regularly to help users dig out valuable information efficiently.

Question 6: What is network information push? Network information push is to use push technology to actively send information that users are interested in to users' computers purposefully and on time according to users' needs. Just like the voice of a radio station, "push" technology actively pushes the latest news and materials to customers, so users don't have to search online.

The main advantages of push technology are:

1, which has low requirements for users and is generally suitable for the general public without special technology;

2. The timeliness is good, and the information source "pushes" the constantly updated dynamic information to the user in time.

Question 7: What does push mean? Users and users are bound together by certain ties, just like interpersonal communication in our daily life.

The so-called push function is similar to that after a message is released, he will let more people know the news through friends and sharing. For example, if I send a message on spacebuilder, if others are interested, they will know about you, your friends, your circle and everything you can know. It is also possible to make friends with you. When you form a circle and an atmosphere, the content you publish can be pushed by sns.

About the push function:

In mobile communication, most smart phones support push function. For example, there is an instant messaging software on your mobile phone, which is connected to the server at runtime; But once you quit, you lose contact. At this time, the push service began to work.

When the program runs in the background, it will adopt such a reminder method, such as reminding you to upgrade and updating the message in real time.

Nowadays, there are more and more users using smart phones. Many people think that there will be no traffic without surfing the internet, but it is not. Smartphones have push function, and emails, weather and some programs will be automatically updated, which is a problem of "stealing traffic" reflected by many users. Even if you are sleeping, the mobile phone is quietly generating traffic through the background.

What does it mean to send the question app push message? The basic principle of pushing is actually similar. In fact, it is to maintain a long TCP connection between the mobile phone and the server through Socket, and realize the communication between the server and the client through this long connection. Therefore, the provider of push service will also provide a library for the reference of third parties. This embedded library will help third-party applications maintain the connection between servers, including permission checking, disconnection and reconnection. In this way, a simple interface is exposed to the third-party developers, who don't have to care about all kinds of complicated technical problems such as disconnection and reconnection, heartbeat detection and so on. Of course, in addition, these sneaky libraries often encapsulate some other interfaces, such as helping you display messages in the notification bar, displaying pages, and even activating your application, transmitting data to the application and displaying it in a certain interface in the application. These functions can greatly simplify the work of app development. Someone asked me what's the difference between pushing and texting? I think these extended functions are the biggest difference from SMS. As for the reason why my friend used HTTP to poll before, there is also a reason, because the HTTP request is finally realized through TCP protocol, but its TCP connection is very short, handshaking is very frequent, which naturally consumes more power, while the HTTP method is based on text communication, so the protocol redundancy is relatively large, and the traffic consumption naturally increases. Moreover, the problem brought by polling mode is that the message sent by the server cannot be obtained within the time interval between two polls. So the real-time performance will be greatly reduced. Long connections do not have these problems, and another advantage is that when your application is not active, it doesn't matter, you can still reach it and improve its activity. Of course, long connections also have their problems, that is, it is more difficult to develop. Moreover, one of the characteristics of mobile phone applications is mobility, and everyone runs with their mobile phones. So when you run into the elevator or tunnel, if the signal is not good, the connection will be broken, and the program will have to be reconnected at this time, which invisibly increases the difficulty of this matter.

Question 9: What is Android Message Push? How is it usually done? Message push actually depends on your business needs. We use aurora push.

If real-time is not needed, it is best to write a round of polling at the client.

After all, the third party's push is basically charged, free to use, either limited in quantity or limited in frequency, and so on.

If you just play, you can use Aurora Push or Baidu Cloud Push. Integration is very simple, all have the current code, which can be run directly.

The implementation of push can be divided into two types.

The server actively pushes messages.

Client timing query message

If you push actively, you can use a long connection, or you can use java socket to keep the connection all the time to realize real-time push (the advantage is that the message is real-time, but the disadvantage is that the server is under great pressure, and the mobile phone consumes electricity and traffic, which is difficult to develop).

If the client inquires regularly, it is to start the timer and how often to check the server to see if there is any data (the advantage is that the development is simple, the client consumes less power and traffic, but the message is not real-time)

Question 10: What does information push service mean? What are the benefits of accepting information push service? In other words, if you close the application, the mobile phone will still receive the information sent by this application.
