Then specifically realize the processing of PCC control in the present embodiment by following step, signaling process figure comprises as shown in Figure 7:

When subscriber equipment during in the roaming place, the access network of subscriber equipment is VPLMN:

Step 301, user equipment registration are to h-AF;

Step 302, h-AF are when subscribing to the signaling paths state, by the attribute of Diameter AAR: the INDICATION_OF_PCC_CAPABILITY_CHANGE indicated value is subscribed to the PCC ability information to h-PCRF among the Specific-Action AVP;

Step 303, h-PCRF determine to carry out end to end by VPLMN to subscriber equipment, and QoS authorizes, but can be IP layer QoS authorizes, h-PCRF then increases message header PCC_CAPABILITY AVP newly in AAA message, and sends to h-AF after adding QOS_AUTHORIZATION_DISABLE (1); The optional information that in reporting message AAA, can comprise the VPLMN at subscriber equipment place;

Step 304, subscriber equipment are initiated service request (SDP Offer) to h-AF;

Step 305, carry out that IP layer QoS authorizes or based on flow based charging when the service needed of user equipment requests, then h-AF is according to the AAA message that reports, issue media information Diameter AAR and give h-PCRF, AF increases QoS-Authorization-Indication AVP in Rx interface AAR message, and interpolation ONLY_CHARGE_NO_QOS (1), the indication subscriber equipment is not authorized with QoS to the h-PCRF request, only does based on flow based charging; Or,

Add pre-authorization (1) (PRELIMINARY SERVICE INFORMATION (1)) among the Service-Info-Status AVP of h-AF in Rx interface AAR message, the indication subscriber equipment is to the h-PCRF pre-authorization;

Step 306, h-PCRF return Diameter AAA message and confirm;

Step 307, IP layer QoS authorizes and based on flow based charging, the direct notifying user equipment of h-AF is initiatively initiated resource request when the business of user equipment requests does not need to carry out; Perhaps h-AF obtains VPLMN information from step 303 reporting message AAA, knows that this VPLMN can not do Dynamic Resource Allocation for Multimedia (i.e. carrying is handled), can do unified the processing at subscriber equipmenies all under this VPLMN.

When subscriber equipment finishes roaming, get back to ownership place, the access network of subscriber equipment is HPLMN:

Step 308, h-PCRF determine that the business of the subscriber equipment of HPLMN carries out the PCC control ability, can carry out QoS and authorize ability, then send RAR message, add PCC_ENABLE (0) in message header PCC_CAPABILITY AVP, indication can be carried out QoS and authorize ability;

Step 309, h-AF return Diameter RAA message to h-PCRF, are used for the Diameter RAR of successful respond step 308;

Step 310, subscriber equipment are initiated business request information to h-AF;

Step 311, h-AF issue media information Diameter AAR, AF is newly-increased QoS-Authorization-IndicationAVP in the Media-Component-Description AVP of Rx interface message AAR, and in newly-increased attribute, adding QOS_AUTH_CAHRGE_REQUIRED (0), the indication subscriber equipment is to HPLMN requirement QoS mandate and based on the charging of flowing; Perhaps,

Do not carry QoS-Authorization-Indication AVP in AAR, the default value of setting this AVP is that subscriber equipment is to HPLMN requirement QoS mandate and based on the charging of flowing;

Step 312, h-PCRF return Diameter RAA message authentication, and trigger the charging of carrying out based on stream.

In the present embodiment, PCRF can not hold disconnected QoS to authorize to be the information of the distribution of dynamic resource to send to AF to the business of subscriber equipment access network, AF issues media information according to the PCC control ability that reports, the indication access network can carry out based on flow based charging the business of subscriber equipment, carries out the triggering based on flow based charging; Or the AF notifying user equipment is initiated resource request.Network is that PCC ability according to actual access network triggers to the strategy of user apparatus service and the control of chargeing in the embodiment of the invention, can not occur causing AF to repeat PCC control request because of the PCC ability of AF request and the difference of Access Network PCC ability, reduce the mutual of Rx interface, reduced network carries out session in application layer to subscriber equipment influence.

Method embodiment four

When subscriber equipment during in the roaming place, the access network of subscriber equipment is VPLMN:

Step 401, user equipment registration are to h-AF;

Step 402, subscriber equipment are initiated SDP Offer request to h-AF;

Step 403, h-AF send the media information Diameter AAR of issuing service, and request VPLMN carries out PCC control;

Step 404, h-PCRF find that the PCC control ability is limited, reply refuse information, newly-increased message header PCC_CAPABILITY AVP in refuse information, and interpolation QOS_AUTHORIZATION_DISABLE (1), indication can't be done Dynamic Resource Allocation for Multimedia (namely can't do carrying handles), authorizes and can be IP layer QoS;

Step 405, the service needed that please ask when subscriber equipment are carried out based on flow based charging, or IP layer QoS authorizes, h-AF can issue media information again, in message header QoS-Authorization-IndicationAVP, add ONLY_CHARGE_NO_QOS (1), the indication subscriber equipment does not require QoS to authorize to h-PCRF, can do based on flow based charging;

Step 406, the h-PCRF information of accepting business, and trigger the PCC control of the subscriber equipment of VPLMN;

Step 407, optional h-PCRF notice ANDSF initiatively initiate resource request to all subscriber equipmenies under this VPLMN;

Step 408, ANDSF notify all subscriber equipmenies under this VPLMN to initiate resource request.

If at user equipment registration after h-AF, h-AF subscribes to the PCC ability information to h-PCRF, then when subscriber equipment end roaming, when getting back to the ownership place access, access network is HPLMN, h-PCRF can report the PCC control ability of HPLMN to h-AF, and the triggering of later PCC control such as the step after method embodiment three steps 308 are not being given unnecessary details at this.
