Embodiment Construction
[0055] The core of the present invention is that when the IP header is compressed on the core network and user equipment of the 3GPP evolved wireless communication system, a user context is created for each user on the core network equipment and the evolved wireless access network equipment respectively, in which User context includes information such as user ID and tunnel context. When it is necessary to transmit the user's IP header compressed data packet between the evolved radio access network device and the core network device, a corresponding tunnel is established for the user; the evolved radio access network device transmits the user's uplink IP header according to its user context information The wireless interface QoS parameters of the compressed data packet are mapped to the bearer network QoS parameters or the bearer network QoS parameters of the user downlink IP header compressed data packet are mapped to the wireless interface QoS parameters. In this way, the IP ...
