A processing method for the resource request in NGN, which includes the following steps: the service control layer in NGN transmits the corresponding resource request to the resource admission control layer after the service control layer receives the service request transmitted by an user; if the bandwidth applied by the resource request can not be satisfied, then the resource admission control layer adds the available bandwidth information into the corresponding resource request refusing message and transmits it to the service control layer when the resource admission control layer refuses the request. The service control layer and the user perform session negotiation of the corresponding service according to the available bandwidth information. The method can optimize QoS resource control, acquire the current resource status when the service control function is failed for resource application, negotiate QoS once again according to the current resource status, in order to performing service access rapidly and high effectively, thereby providing better service for users.
