Abstract: The present invention relates to the data card field and discloses a method and an apparatus for updating a data card, which implements the updating of the data card when a data card driver is not installed on a PC, and makes it convenient for a user to update the data card. The present invention includes: implementing a connection between a computer and a data card through a standard device interface of the computer; virtualizing the data card as a standard device of the computer and obtaining class information, subclass information, and protocol information of the standard device through the standard device interface; and according to the obtained class information, subclass information, and protocol information of the standard device, determining a system driver corresponding to the standard device, and providing a system driver updating service for the data card.

Abstract: A traffic control method, a traffic controlling device, and a terminal are provided, which relate to the field of communications technology. The traffic control method includes the following. A working temperature of equipment is monitored. It is determined whether the working temperature reaches a control temperature. If the working temperature reaches the control temperature, a rate of data interaction between the adjacent function layers is controlled. The adjacent function layers are two random adjacent function layers in a Transmission Control Protocol/Internet Protocol (TCP/IP) 7-layer model. Therefore, a user can use equipment normally when power consumption of wireless terminal equipment is reduced.
