Qos guarantee method and gateway

Abstract

The present disclosure relates to a QoS guarantee method. In one example method, a control plane gateway obtains a QoS parameter. The QoS parameter comprises an allocation/retention priority (ARP) and a QoS class identifier (QCI). The control plane gateway maps the QoS parameter to QoS guarantee information. The QoS guarantee information comprises a differentiated services code point (DSCP) parameter. The control plane gateway sends the QoS guarantee information to a user plane gateway. The QoS guarantee information is to be used by the user plane gateway for QoS marking.

 obtaining, by a control plane gateway, a QoS parameter;   mapping, by the control plane gateway, the QoS parameter to QoS guarantee information;   sending, by the control plane gateway, the QoS guarantee information to a user plane gateway; and   performing, by the user plane gateway and according to the QoS guarantee information, QoS guarantee at a granularity of a bearer or at a granularity of a service flow.   
     
     
         2 . The method according to  claim 1 , wherein the QoS parameter comprises a guaranteed bit rate of a service flow, the QoS guarantee information being bandwidth guarantee information, and wherein performing the QoS guarantee comprises:
