An over-the-air (OTA) upgrade method includes obtaining, by a server, a new version of encrypted data and an old version of encrypted data of system software applied to a mobile terminal, decrypting, by the server, the new version of encrypted data to obtain a new version of original data, decrypting, by the server, the old version of encrypted data to obtain an old version of original data, performing, by the server, differentiation on the new version of original data and the old version of original data to obtain differential data, generating, by the server, OTA data based on the differential data, and sending, by the first server, the OTA data to the mobile terminal.

Over-the-air upgrade method and related apparatus

Provided is a solid catalyst component for olefin polymerization, which comprises Mg, Ti, a halogen and an electron donor. The electron donor is selected from at least one of ring-substituted ether-acid ester compounds of the general formula (I). Also provided are a catalyst containing the solid catalyst component and the application of the catalyst in reactions of olefin polymerization, particularly in the reaction of propylene polymerization.

Catalyst component for olefin polymerization and application thereof

A universal serial bus (USB) device communication method that relates to the field of communications includes: receiving, by a USB device, a device type query message sent by a peer device, where a human interface device (HID) descriptor and a HID report descriptor are added to a driver of the USB device; sending, by the USB device according to the HID descriptor and HID report descriptor, a query response message that carries a HID identifier to the peer device, where the HID identifier is used to enable the peer device to identify the USB device as a HID device; and encoding and encapsulating, by the USB device, data to be sent to generate a HID packet, and sending the HID packet to the peer device, or receiving a HID packet from the peer device, and decapsulating and decoding the received HID packet, where the HID packet carries a data type and data usage manner information.

USB device communication method, device and system wherein a human interface device (HID) descriptor and report are added to a driver of USB device
