摘要

A method and system for updating quality of service (QoS), the method comprising: in a procedure of service, a user equipment (UE) sends to a packet gateway (PGW) a QoS update request or a QoS confirmation instruction; the PGW initiates an IP connection access network (IP-CAN) session modification process to update QoS after receiving the QoS update request or the QoS confirmation instruction. The method allows users to experience the improved QoS before determining whether to accept it or not, thus enabling providing service QoS in accordance with the requirement of users.
