BANDWIDTH ADJUSTMENT METHOD, DEVICE AND SYSTEM

摘要

Disclosed is a bandwidth adjustment method. The method comprises: (101) receiving service type information sent by a gateway device, of a current service; and (102) adjusting the bandwidth currently used by the current service according to the service type information, so as to ensure the quality of service (QoS) of the current service, the bandwidth currently used by the current service being the bandwidth indicated by a bandwidth parameter configured for the current user according to an obtained bandwidth parameter of the current user. By means of the present invention, the bandwidth can be limited and QoS can be ensured for different users and different services.
