摘要： A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like.

摘要： A streaming media resource downloading method includes: determining that a first media file is a to-be-downloaded media file according to first network bandwidth, where the first media file is included in a streaming media resource corresponding to the first network bandwidth, and the first media file includes N data blocks; and after an (n−1)th data block in the first media file is downloaded, and before an nth data block in the first media file is downloaded, determining a length of the to-be-downloaded nth data block according to network bandwidth reduction times in an executed first media file downloading process, where 1≦n≦N. Therefore, a length of a to-be-downloaded data block is adjusted according to the network bandwidth reduction times in the first media file downloading process, so that video playing can better adapt to a bandwidth change, and streaming media resource switching times are reduced.
