Step 505: The policy server receives an NSP access session response message returned by the policy execution body, and indicates whether the NSP is allowed to provide the required service for the user. If allowed, the sent content further includes the policy server. The generated policy is guaranteed according to the quality of service required by the user, and is identified by the access line of the access session. . The message includes the following parameters:

DslLineld, an access line used to identify a user in the area network, used to match DslLineld in the NSP access session request message. Specifically, if the execution of the policy enforcement entity in the broadband network is successful, it indicates that the broadband network can provide the user with the guarantee of the quality of service, and the NSP is instructed to provide the service for the user; if the execution of the policy enforcement entity in the broadband network fails, the broadband network cannot be Provide users with corresponding service quality assurance, indicating that NSP can not provide services for users. Step 506: The NSP responds to the service request initiated by the user according to the message returned by the policy server. Specifically, if the policy server instructs the NSP to provide a service for the user, the process of initiating the service response is performed, and the method for responding to the service in the prior art is applicable to this step, and is not described again; otherwise, the service request is rejected. Embodiment 4 FIG. 6 is a schematic diagram of a policy server interacting with an NSP to query a specific access session for the NSP, and the method includes the following steps: Step 601: The NSP senses a policy of a user in real time, and detects a current user bandwidth information, for example, current bandwidth information of the user. . Step 602: The NSP sends an NSP access session query message, including the identifier information of the access session, where the access line of the access session requests the policy server to query the bandwidth of the specific session, and the NSP does not need to The depth perception carries the network policy type, topology information, and network status information. For example, the NSP access session query message includes DslLineld, an access line for identifying a user in the area network. Step 603: The policy server queries the corresponding policy information according to the user access line identifier, and returns the queried policy information by using an NSP access session query response message, including at least one of the following: current uplink and downlink bandwidth and maximum available.
