Embodiment
Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
The network architecture of 3GPP as shown in Figure 1, UE inserts the MTC server by EPS and UMTS, constitutes the MTC system, realizes the MTC business.Introducing a plurality of embodiment of the present invention below, is that the basis is implemented with this MTC system all.
With reference to Fig. 3, show a kind of flow chart of steps that is used for the policy control method of Packet Service according to the embodiment of the invention, may further comprise the steps:
Step S302:PCRF receives a user's of user's group QoS authorization requests;
For example, be example with the MTC system, PCRF receives the IP-CAN conversation request of a user A among the MTC Group.
Step S304:PCRF judges this user's guarantee bandwidth demand and organizes the guarantee bandwidth summation of mandate above the signatory bandwidth GSGB that ensures of the group of user's group for the user;
For example, the PCRF of MTC system judges the desired bandwidth of IP-CAN conversation request of user A, also surpasses the signatory bandwidth GSGB that ensures of group of this MTC Group with the shared bandwidth summation of the mandate MTC user of this MTC Group such as user B, C and D.
Step S306:PCRF is the QoS of the described guarantee bandwidth of this subscriber authorisation.
For example, PCRF authorizes the QoS of the desired guarantee bandwidth of its IP-CAN conversation request for user A.
Visit is not simultaneously controlled in the correlation technique, and present embodiment has effectively been controlled the bandwidth resources that a user organizes CU, solve cellular carrier in the correlation technique and can't effectively control the problem of the Internet resources that MTC Subscriber takies, avoided the user at a plurality of MTC equipment of same MTC Subscriber when section is carried out Operational Visit simultaneously sometime, the user capture that causes is limited, thereby has promoted user experience.
With reference to Fig. 4, show the flow chart of steps that is used for the policy control method of Packet Service according to the another kind of the embodiment of the invention, may further comprise the steps:
Step S402:PCEF/BBERF sets up request to the session that route agent sends a user of user's group;
For example, the PCEF/BBERF of MTC system sends the session foundation request of the user A of MTC Group1 to the Diameter of the MTC DRA of route agent.The information such as group id that can comprise user ID, PDN (Packet Data Network, Packet Data Network) sign and affiliated user group in the request are set up in this session.
The procotol difference that different piece is used in the grouping system sends session by PCEF or BBERF and sets up request, has considered the network characteristics of present grouping system to greatest extent, makes the embodiment of the invention with a wide range of applications.
Step S404: route agent check whether be under this user user's group selection PCRF, if, execution in step S408 then, if not, execution in step S406 then;
For example, DRA checks whether be that the affiliated MTC Group1 of user A has selected PCRF.This step is an example with non-selected PCRF.
Step S406: route agent is the user's group selection PCRF under this user;
For example, select PCRF1 for the MTC Group1 under the user A.
Because not mutual between a plurality of PCRF in the system, therefore if do not select same PCRF, just can't the Internet resources that a user organizes CU be carried out in time, calculating exactly.By being that all users that a user organizes select same PCRF, can organize the resource row centralized control of CU to this user, in time, accurately grasp the resource occupying situation of this user's group.
Step S408: request is set up in the session that sends this user to the PCRF that selects;
In this step, can can set up request mode sends session foundation request from this user to the PCRF that selects by transmitting session by route agent, perhaps, return the redirect message that carries PCRF information by route agent to PCEF/BBERF, set up request by PCEF/BBERF to the session that the PCRF that selects sends this user again.
Route agent sets up request by forwarding or redirected mode to the session that the PCRF that selects sends the user, has made full use of the technical characterstic of existing grouping system, and realization is simple, saves cost.
Step S410:PCRF judges that whether this user's the session request of setting up is that request is set up in the session of the first user of user's group under it, if, execution in step S412 then, if not, execution in step S416 then;
In this step, PCRF judges that the conversation request of user A is the first session foundation request of MTC Group1.
Step S412:PCRF sends signatory document request to SPR;
Should can carry the information such as group id that user ID, PDN sign and affiliated user organize in the signatory document request.
Need to prove, judge that at PCRF the conversation request of user A be to set up other session of request when setting up request except that the first session of MTCGroup1, also can be once more to the SPR transmission document request of contracting.
Step S414:PCRF receives the signatory document of SPR feedback and replys, and obtains GSGB wherein;
Preserve the signatory bandwidth GSGB information that ensures of group of user group among the SPR, SPR replys by signatory document this information is sent to PCRF, is obtained the GSGB of user's group under the user by PCRF.
By step S410-S414, when PCRF sends first conversation request the user of user's group, promptly obtain GSGB to SPR, can effectively calculate this user and organize the bandwidth that interior authorized user takies, so that the Internet resources that this user's group is taken control effectively.
Step S416:PCRF judges whether guarantee bandwidth that this session request of setting up requires and the guarantee bandwidth summation of organizing mandate for the user surpass the signatory bandwidth GSGB that ensures of group of user's group, if, execution in step S420 then, if not, execution in step S418 then;
For example, because of the conversation request of user A is a first conversation request among the MTC Group1, therefore, still do not have other authorized user among the MTC Group1, PCRF judges whether bandwidth that the conversation request of user A requires surpasses the GSGB of user's group.This step is an example not surpass.
Step S418:PCRF is that the QoS that ensures bandwidth is authorized in this user's the session request of setting up, and flow process finishes;
Step S420:PCRF refuses this user's session and sets up request, and flow process finishes.
In this step, when bandwidth did not satisfy the demands, PCRF refused this user's session and sets up request, and in reality was carried out, PCRF can not have the bandwidth of guarantee according to the bandwidth situation of system yet for subscriber authorisation.
No matter be the session foundation request of refusing user's,, guaranteed to greatest extent that all other users organize user's Internet resources use still for subscriber authorisation does not have the QoS that ensures bandwidth.
