Have only the situation of an ASN GW for a multicast and broadcast territory, can not need the MBS agent entity, the PCRF entity can directly send to the PCC rule policy execution entity among the ASN GW.

The concrete steps that the PCRF entity directly sends to the PCC rule policy execution entity among the ASN GW can realize like this: the PCRF entity sends to policy execution entity among the ASN with the PCC rule; Described PCRF entity sends the MBS service authorization and responds the server to MBS, and comprising described PCC rule, described MBS server is installed described PCC rule; Policy execution entity in the access service network sends the service authorization request to the PCRF entity; After described PCRF receives this service authorization request, give policy execution entity in the described access service network, or the PCC rule is sent to policy execution entity among the ASN described PCC rule downloading; Policy execution entity in the described access service network is installed described PCC rule.

And in PCRF entity distribution PCC procedure of rule, the PCRF entity can be directly or by self strategy distribution entity transmission PCC rule.

The PCRF entity also can carry out service authorization and generate the PCC rule on different opportunitys.Such as: set up in the process in the MBS business, perhaps, when terminal to apply adds MBS ip multicast group.

Lift the technical scheme that specific embodiment is described the inventive method in detail below in conjunction with Fig. 7～Figure 12.Wherein, embodiment one of the inventive method and embodiment two set up in the process in the MBS business, realize service authorization, generate the PCC rule, and install and carry out the PCC process of rule; The embodiment the three, four, the 5th of the inventive method when terminal to apply adds MBS ip multicast group, realizes service authorization, generates the PCC rule, and installs and carry out the PCC process of rule.

In the embodiment one of the inventive method shown in Figure 7, the PCRF entity directly or by strategy distribution entity is issued the MBS server with the PCC rule, the MBS server can charge according to the charging policy in the PCC rule, and the qos policy in the PCC rule and information of classifier when setting up carrying, access service network be handed down to policy execution entity in the access service network, the SFA that policy execution entity comprises, DPF, one or more entities in Accounting Client and the MBS agent entity are carried out, and the MBS server also can be handed down to the information in the PCC rule in the access service network other policy execution entity by the MBS agency.

Referring to shown in Figure 7, the idiographic flow of the embodiment one of the inventive method is as follows:

Step 701:MBS server sends MBS service authorization request message to the PCRF entity when setting up a MBS business.

After step 702:PCRF entity is received this service authorization request message, from MBS service management entity, obtain corresponding MBS business information, and carry out service authorization, generate the PCC rule according to described MBS business information and local network strategy.

The MBS business information comprises bandwidth, reservation priority, the media description information that MBS requires, MBSIP classifier rules etc.The IP classifier rules comprises IP source address, IP destination address, source/destination slogan and IP protocol type etc.IP source address is MBS server/MBS provider address, and the IP destination address is the ip multicast address.Ip multicast group and ip multicast address and port numbers are that MBS server/MBS provider is this MBS traffic assignments as application entity (AF).

The MBS server is issued in the service authorization response that step 703:PCRF entity will contain the PCC rule.

Step 704:MBS server is installed this PCC rule.

MBS DPF among the step 705:ASN GW adds MBS distribution of services tree to the MBS server requests, is perhaps initiated to set up the MBS distribution of services tree of a multicast domain to ASN GW by the MBS server.

Step 706:MBS server is handed down to policy execution entity among the ASN with the qos policy in the described PCC rule and IP classifier rules, policy execution entity comprises one or more among SFA, MBS DPF among the ASN, Accounting Client and the MBS agency, and the MBS server also can be given other policy execution entity in the access service network with the PCC rule downloading by the MBS agency.

The PCC rule that each policy execution entity utilization is received among the step 707:ASN is carried out policy installation.

Step 708:MS sends the request that adds MBS ip multicast group to the MBS server.

After step 709:MBS server is received the request that adds MBS ip multicast group, after this MS authentication passed through, authorize this MS to add MBS ip multicast group.

Because the PCC rule at the MBS business, promptly has the IP grader of identical MBS downlink bandwidth, charging regulation and MBS business, therefore, the MS in the same multicast group carries out same PCC rule.

In this embodiment, if need the MBS agency to transmit as the process points and the signaling of MBS signaling in the ASN among the ASN GW, then in the step 705, the MBS DPF among the ASN GW can add MBS distribution of services tree to the MBS server requests by the MBS agency.That is: MBS DPF can send the MBS agent entity that joins request, and the MBS agency sends to the MBS server again.

When distribution PCC rule, the MBS server can be given the MBS agent entity with the PCC rule downloading earlier, the MBS agent entity carries out the execution of MBS QoS strategy in the ASN and the fractionation of PCC rule, and other Policy Enforcement Points that the PCC strategy after will splitting is again issued among the ASN go to carry out.

Referring to shown in Figure 8, the idiographic flow of the embodiment two of the inventive method is as follows:

Step 801～step 805: identical with step 701～step 705.

When step 806～807:GW adds the multicast distribution tree to the MBS server requests, after the PCRF entity is received the service authorization request of GW, the PCRF entity directly or pass through strategy distribution entity, the service authorization response that will contain this PCC rule sends to the policy execution entity among the ASN, comprises one or more in SFA, MBS DPF, Accounting Client and the MBS agent entity among the ASN.

Policy execution entity among the step 808:ASN utilizes this PCC rule to carry out policy installation.

Step 809～step 810 is identical with step 708～709.

Certainly, if need the MBS agency to transmit as the process points and the signaling of MBS signaling in the ASN among the ASN GW, then the MBS DPF among the ASN GW can add MBS distribution of services tree to the MBS server requests by the MBS agency.That is: MBS DPF can send the MBS agent entity that joins request, and the MBS agency sends to the MBS server again.

GW can also send the service authorization request to the PCRF entity by the MBS agent entity, and GW sends the service authorization request to the MBS agent entity, and the MBS agent entity sends to the PCRF entity with this service authorization request again.

The PCRF entity is when distribution PCC rule, the PCRF entity can also be handed down to the MBS agent entity earlier with the PCC rule, carry out the execution of MBS QoS strategy in the ASN and the fractionation of PCC rule by the MBS agent entity, other Policy Enforcement Points that the PCC strategy after will splitting is again issued among the ASN go to carry out.

The difference of embodiment two and embodiment one is: embodiment two be by the policy execution entity among the ASN to PCRF entity requests PCC rule, PCRF gives the PCC rule downloading policy execution entity among the ASN again; Embodiment one issues the PCC rule by the policy execution entity of MBS server active in ASN.
