<p>A method for processing a resource request in NGN comprises the following steps: after receiving a service request sent by a user, a service control layer in NGN sending a corresponding resource request to a resource and admission control layer; and if the bandwidth applied in the resource request cannot be satisfied, the resource and admission control layer including the available bandwidth information into the corresponding resource request refusing message when refusing the request and transmitting it to the service control layer. The service control layer and the user perform session negotiation on the corresponding service according to the available bandwidth information. This method can optimize QoS resource control, and when service control function fails in applying resources, it can acquire the current resource status, and negotiate QoS again according to the current resource status so as to access services rapidly and efficiently and provide better services for the user.</p> |
