1. A method for processing a data packet, the method comprising:
- receiving, by a user equipment, compression configuration information of an application layer packet from a network device;
performing, by the user equipment, compression processing on the application layer packet at an access layer according to the compression configuration information, and adding a compression initialization identifier to a header of the compressed application layer packet, wherein the compression initialization identifier indicates an initial packet from which compression restarts;
sending, by the user equipment to a target network device, the compression configuration information received from the network device when the user equipment is handed over to a target network; and
receiving, by the user equipment, a compression configuration response returned by the target network device, wherein the compression configuration response indicates compression configuration information of the target network device.

Abstract
The present invention provide a method for processing data packet and apparatus and the method includes: receiving or sending compression configuration information of an application layer packet; and performing compression processing or decompression processing on the application layer packet according to the compression configuration information. By using the foregoing method, compression and decompression processing of the application layer packet can be implemented, thereby reducing overheads of packet transmission and improving utilization of a network resource.
