Claim:
1. A method of establishing a radio bearer, comprising: segmenting, by a User Equipment, UE, IP data streams of a higher-layer service into a plurality of service data streams with different Quality of Service, QoS, and determining QoS parameters corresponding to each service data stream, according to media parameter information of the higher-layer service; sending, by the UE, a Radio Bearer Setup Request carrying information of the service data streams of the higher-layer service and the corresponding QoS parameters to a radio Access Point, AP; establishing, by the UE, corresponding radio bearers for the service data streams according to QoS parameters, determined by the AP, without any input from a core network device, available to the service data streams in a Radio Bearer Setup Response returned from the AP upon reception of the Radio Bearer Setup Response, and establishing mapping relationships between the service data streams and the corresponding radio bearers; and returning, by the UE, a Radio Bearer Setup Complete Response message to the AP; wherein before the UE sends the Radio Bearer Setup Request to the AP, the method further comprises: for each service data stream, determining, by the UE, whether there is a radio bearer capable of satisfying the QoS of the service data stream between the UE and the AP; if so, then sending a Radio Bearer Modify Message to the AP to instruct the AP to reallocate a radio resource for the radio bearer capable of satisfying the QoS of the service data stream; if not, then determining information of the service data stream and the corresponding QoS parameters need to be carried in the Radio Bearer Setup Request.
