What does a push service on a cell phone do?
iOS push (APNS) relies on one or several system-resident processes to operate and is global (taking over the push of messages from all apps), so it can be seen as independent of apps, and is a communication between the device and the Apple servers, rather than the app's provider servers.
Tencent QQ's servers (Providers) send notifications to Apple's corresponding servers (APNs), which are then relayed on top of your Devices. When you receive a notification and open the app, you start receiving data from Tencent's servers, which is the same as what you saw in the notification, but through two different channels.
And Android, on the other hand, is different, more like a traditional desktop computer system. Each app that needs to be pushed in the background has its own separate background process that communicates with its own server and exchanges data. In addition, Android also has a GCM (Google Cloud Message), which is similar to APNS, and is optional, not mandatory, for developers.
To learn more about mobile push services, go to Aurora, which is relatively simple to use. Users register an account and then choose to create an application, upload the application name and application package (iOS applications need to upload the iOS development certificate and certificate password) to complete the creation. Enterprises wanting to push messages only need to select the app, click "Send Notification" in "Push", fill in the push content and click "Send Now" at the bottom of the page.
