Fig. 2 C is a QoS authorization control flow chart in the embodiment of the invention three, and shown in Fig. 2 C, the QoS authorisation process process that AF triggers may further comprise the steps:

Step 201C:AF, (IP Multimedia System, (Proxy-Call Session Control Function P-CSCF) sets up the mutual of application layer with MS to call session control agent entity IMS) as IP Multimedia System.

Step 202C:AF carries out the mandate of operation layer to MS, and sends the service parameter authorization requests to PCRF, and the qos parameter and the operation layer related information of operation layer mandate is handed down to PCRF.The operation layer related information comprises the Streaming Media descriptor that AF provides to PCRF at least, for example, WiMAX content (WiMAX Content), WiMAX content comprise resource reduction (Reduced Resources) indication, QoS priority information such as (QoS Priority).If MS is positioned at visited network, AF will be based on user's sign, find local PCRF (H-PCRF) as the privately owned sign of IMS, and the qos parameter and the operation layer related information of operation layer mandate is handed down to H-PCRF.

Step 203C~step 204C:PCRF carries out strategic decision-making according to the qos parameter of operation layer mandate and policy information and user signing contract information, after determining that local network can satisfy the qos parameter of AF requirement, PCRF can be mapped as the qos parameter of operation layer mandate the IP qos parameter, generate the PCC rule, the QoS information that comprises in this PCC rule can be the qos parameter of operation layer mandate, also can be the IP qos parameter, PCRF sends the service parameter authorization requests to PCEF then, and the PCC rule is offered PCEF.If PCRF determines local network and can't satisfy the qos parameter that AF requires, then notify the AF local network can't satisfy qos parameter, carry out subsequent treatment by AF, as revising qos parameter.If MS is positioned at visited network, then carry out strategic decision-making according to the qos parameter of operation layer mandate and generate the PCC rule, and this PCC rule is offered visit PCRF (V-PCRF) by H-PCRF, V-PCRF offers visit PCEF (V-PCEF) with the PCC rule.Further, V-PCRF can determine new PCC rule according to the regular and local control strategy decision-making of the PCC that H-PCRF provides, and then this PCC rule is offered V-PCEF.If MS is positioned at visited network, still, do not dispose the PCC control architecture in the visited network, then H-PCRF is with the decision making function entity V-PF of PCC rule downloading to visited network, and the function class of V-PF and V-PCRF is seemingly.At this moment, carry out protocol conversion by V-PF or the special protocol converter that is provided with, convert the PCC rule to WiMAX network discernible parameter, and be handed down to service flow authorized entity SFA use according to the new parameters such as QoS mandate of control strategy decision-making generation of local network.

After step 205C:PCEF receives the PCC rule, the PCC rule of Gx/Ty interface is converted to the PCC rule of Interface R3, sends the service parameter authorization requests to SFA then, the PCC rule is offered SFA.

After step 206C:SFA receives the PCC rule, if the QoS information that comprises in the PCC rule is the qos parameter of operation layer mandate, then SFA is mapped as the access bearer qos parameter with the qos parameter of operation layer mandate, if the QoS information that comprises in the PCC rule is the IP qos parameter, then SFA is mapped as the access bearer qos parameter with the IP qos parameter, after determining that according to the Internet resources situation of local ASN and the QoS control strategy in the PCC rule local network can satisfy the qos requirement of PCC rule, carry out QoS and authorize and carry out the QoS control strategy.If SFA determines local network and can't satisfy the qos requirement of PCC rule, then can't satisfy qos parameter by PCEF, PCRF notice AF local network, carry out subsequent treatment by AF, as revising qos parameter.If PCEF only with ASN-GW in SFA directly link to each other, then SFA sends to the server data stream detection information in the PCC rule DPF, reaches the charging policy in the PCC rule is sent to Accounting Client/charging proxy; If PCEF respectively with ASN-GW in SFA, DPF link to each other with Accounting Client/charging proxy, then PCEF splits the PCC rule, be the QoS control strategy in the PCC rule to the PCC rule that SFA provides, and the server data stream detection information in the PCC rule sent to DPF, the charging policy in the PCC rule is sent to Accounting Client/charging proxy.

Step 207C:SFA finishes resource allocation according to qos requirement and carrying is set up.

Step 208C~step 211C:SFA returns the service parameter authorization response to PCEF; After PCEF receives the service parameter authorization response, return this service parameter authorization response to PCRF; After PCRF receives the service parameter authorization response, return this service parameter authorization response to AF.After AF receives the service parameter authorization response, continue the upper-layer service flow process.

In the operation flow, DPF detects information according to the server data stream of receiving data stream is carried out classification and Detection, and charging proxy is carried out based on the charging of flowing according to the charging policy of receiving.

Identical in all the other schemes and the embodiment of the invention one in the present embodiment.

Fig. 2 D is a QoS authorization control flow chart in the embodiment of the invention four, and shown in Fig. 2 D, the QoS authorisation process process of setting up the IP-CAN carrying that ASN triggers may further comprise the steps:

Step 201D is identical with step 201C.

Step 202D:MS initiates the IP-CAN carrying and sets up or revise request, and this IP-CAN carrying sets up or revise the home address that carries MS in the request and beared information, as WiMAX session identification, SFA sign, is used for bearing binding.

Step 203D~step 204D:SFA sends the service parameter authorization requests to PCEF; After PCEF receives the service parameter authorization requests, the service parameter authorization requests of Interface R3 is converted to the service parameter authorization requests of Gx/Ty interface, sends this service parameter authorization requests to PCRF then.If MS is positioned at visited network, then SFA sends the service parameter authorization requests to V-PCEF, after V-PCEF receives the service parameter authorization requests, sends this service parameter authorization requests to V-PCRF.V-PCRF sends service parameter authorization requests request PCC rule to the policy deciding functional entity H-PCRF of home network.

After step 205D~step 206D:PCRF receives the service parameter authorization requests, send this service parameter authorization requests to AF, the request application layer message is as the qos parameter of operation layer mandate, data map information etc.Data map information comprises the Streaming Media descriptor at least.After AF receives the service parameter authorization requests, send the service parameter authorization response, will offer PCRF corresponding to operation layer mandate qos parameter and the data map information of MS (identifying) with home address to PCRF.If MS is positioned at visited network, then AF sends the service parameter authorization response to V-PCRF.

Step 207D~step 208D:PCRF carries out strategic decision-making according to the qos parameter of operation layer mandate, after determining that local network can satisfy the qos parameter of AF requirement, generate the PCC rule, PCRF sends the service parameter authorization response to PCEF then, and the PCC rule is offered PCEF.If PCRF determines local network and can't satisfy the qos parameter that AF requires, then notify the AF local network can't satisfy qos parameter, carry out subsequent treatment by AF, as revising qos parameter.If MS is positioned at visited network, after V-PCRF receives the service parameter authorization response, the qos parameter of operation layer mandate is offered H-PCRF.H-PCRF carries out strategic decision-making according to the qos parameter of operation layer mandate, determine that local network can satisfy the qos parameter that AF requires after, generate the PCC rule, H-PCRF returns the service parameter authorization response to V-PCRF then, and this PCC rule is provided.Further, new PCC rule is determined in the V-PCRF PCC rule that can provide according to H-PCRF and the strategic decision-making of local network.V-PCRF sends the service parameter authorization response to V-PCEF, and the PCC rule is offered V-PCEF.If MS is positioned at visited network, still, do not dispose the PCC control architecture in the visited network, then H-PCRF is with the decision making function entity V-PF of PCC rule downloading to visited network, and the function class of V-PF and V-PCRF is seemingly.At this moment, carry out protocol conversion by V-PF or the special protocol converter that is provided with, convert the PCC rule to WiMAX network discernible parameter, and be handed down to service flow authorized entity SFA use according to the new parameters such as QoS mandate of control strategy decision-making generation of local network.
