What does Wap Push mean?

PUSH (WAP-PUSH), also called service information or push information, is a special format of text message.

WAP is like the Internet. It is a network with rich content. How users find their favorite sites and how to find their favorite businesses on a site often takes a long time.

WAP PUSH can send a link to a certain site or a certain business to a mobile phone that supports the WAP PUSH function through text messages. In this way, you only need to read the text message (service information) and open the link in the text message. link, you can directly access the business.

Therefore, WAP PUSH realizes the combination of SMS and WAP services, saving you time in searching for services and making it easier for you to directly find and use your favorite services. Regardless of whether the PUSH message is opened by the user, it will remain in the "push inbox" of the mobile phone, and the user can open it repeatedly.

wap push means a text message with a link, which can guide you to the wap website. It is sent through the SP gateway, using software and mobile interfaces.

Extended information

The WAP PUSH framework mainly includes three functional parts: push initiator (PI: PUSH initiator), push proxy gateway (PPG: PUSH ProxyGateway) and push client (PC: PUSH client). The PI is in the Internet and the PC is in the WAP domain. The protocols used by PI and WAP clients are different, and a protocol conversion gateway PPG needs to be established in the middle.

PPG communicates with PI through Push Access Protocol (PAP: PUSH Access Protocol) and completes the data transmission task of pushing information to the client through Push Space Transfer Protocol (PUSH OTA: PUSH over-the-Air).

PPG completes most of the work in the push architecture, including access from the Internet to mobile networks, as well as authentication, security, client control and other related work. The main services provided by PPG include: PI identification, authentication and access control, parsing push content according to data type definition (DTD), and error detection and correction;

Client addressing and information transmission, PAP and PUSH Protocol conversion between OTAs, compressing and compiling information to improve transmission efficiency in wireless channels.

In addition, PPG can also implement multicast and broadcast through the alias mechanism, that is, mapping some specific address aliases to multicast or broadcast operations. The specific solution can be determined by the system implementer. Different customers have different capabilities. PPG is also responsible for responding to PI's client capability query requests so that PI can build appropriate content formats for different clients.
