A processing method for bandwidth control, comprising: acquiring, by a Policy and Charging Rules Function server, a set of configuration parameters comprising a cell identifier of a cell where a mobile terminal is located from a request for configuring a bandwidth control policy sent by a network access server or a service network gateway to the Policy and Charging Rules Function server when detecting that the mobile terminal is activated or the mobile terminal is performing a cell handover; and dynamically configuring, by the Policy and Charging Rules Function server, a bandwidth control policy for the mobile terminal according to the set of configuration parameters and a set of bandwidth control policies preconfigured by an operator, wherein the set of bandwidth control policies comprises a bandwidth control policy corresponding to the cell identifier; characterized in that the configuring process further comprising: sending, by the Policy and Charging Rules Function server, the bandwidth control policy to the network access server or the service network gateway; sending, by the network access server or the service network gateway, in real time, when determining that the configured bandwidth control policy comprises a first bandwidth control sub-policy corresponding to an air interface bandwidth control identifier, the first bandwidth control sub-policy to a radio network controller, allowing the radio network controller to implement the first bandwidth control sub-policy; and implementing, by the network access server or the service network gateway, in real time, when determining that a second bandwidth control sub-policy, which needs to be locally implemented, exists in the bandwidth control policy, the second bandwidth control sub-policy in the bandwidth control policy. acquiring, by a Policy and Charging Rules Function server, a set of configuration parameters comprising a cell identifier of a cell where a mobile terminal is located from a request for configuring a bandwidth control policy sent by a network access server or a service network gateway to the Policy and Charging Rules Function server when detecting that the mobile terminal is activated or the mobile terminal is performing a cell handover; and dynamically configuring, by the Policy and Charging Rules Function server, a bandwidth control policy for the mobile terminal according to the set of configuration parameters and a set of bandwidth control policies preconfigured by an operator, wherein the set of bandwidth control policies comprises a bandwidth control policy corresponding to the cell identifier; characterized in that the configuring process further comprising: sending, by the Policy and Charging Rules Function server, the bandwidth control policy to the network access server or the service network gateway; sending, by the network access server or the service network gateway, in real time, when determining that the configured bandwidth control policy comprises a first bandwidth control sub-policy corresponding to an air interface bandwidth control identifier, the first bandwidth control sub-policy to a radio network controller, allowing the radio network controller to implement the first bandwidth control sub-policy; and implementing, by the network access server or the service network gateway, in real time, when determining that a second bandwidth control sub-policy, which needs to be locally implemented, exists in the bandwidth control policy, the second bandwidth control sub-policy in the bandwidth control policy. sending, by the Policy and Charging Rules Function server, the bandwidth control policy to the network access server or the service network gateway; sending, by the network access server or the service network gateway, in real time, when determining that the configured bandwidth control policy comprises a first bandwidth control sub-policy corresponding to an air interface bandwidth control identifier, the first bandwidth control sub-policy to a radio network controller, allowing the radio network controller to implement the first bandwidth control sub-policy; and implementing, by the network access server or the service network gateway, in real time, when determining that a second bandwidth control sub-policy, which needs to be locally implemented, exists in the bandwidth control policy, the second bandwidth control sub-policy in the bandwidth control policy.
