What is information release?

Information release is the main information transmission mode of LBS to user terminals, and it is an important way for users to obtain location and related information. With the rapid development of Web technology, information publishing technology has gradually developed from the previous broadcast service mechanism to the push service mechanism. This section mainly introduces information broadcasting, information customization, information extraction and information push service.

There are three main ways to realize information push technology.

(1) message mode

According to the information requirements submitted by users, relevant information is sent to users through e-mail or other message systems. This method is not very interactive and mandatory, and the requirements for resources and information flow are not high. It can be seen that this is the weakest push, but it is easy to achieve.

(2) Agency mode

By using the proxy server, users can search the information content that users are interested in on the Internet regularly or at intervals specified by users, and then push the results to users. The request and push of information is realized through agents, which is transparent to users.

(3) Channel mode

Provide a complete set of integrated application environment, such as push server, client components and related development tools. It defines some sites as channels in the browser. The push server is responsible for collecting information to form channel content and then pushing it to users, while the client component receives incoming data and submits instructions, and processes the data according to the relevant information required by users.
