As shown in fig. 1, the whole network of WiMAX comprises:
(1) client (SS/MS): the user uses this devices accessing WiMAX network.
(2) accessing business network (ASN): ASN is defined as the network function set that the WiMAX terminal provides the wireless access service.ASN has comprised BS and ASN-GW network element.Wherein the major function of BS network element is: provide BS to be connected L2 connection, RRM etc. with MS; The major function of ASN-GW network element is: for MS authentication，authorization，accounting function provides client functionality, provide for MS and switch in the Relay function (such as IP address assignment), ASN of L3 information etc.
(3) connect service network (CSN): CSN is defined as the WiMAX terminal IP Connection Service is provided.The major function that CSN provides is: the IP address assignment of MS, Internet access, AAAproxy or server, based on authorization control of user etc.
Three above-mentioned parts communicate by the interface from R1 to R6 between its logic entity, and each network element and interface relationship are as shown in Figure 1.
The effect of ASN mainly comprises the following aspects: guarantee two layers of establishment of connection between WiMAX terminal and the WiMAX base station; RRM; The optimal selection of Network finding and WiMAX user network service provider; Under the proxy-mobile IP pattern, serve as acting server control WiMAX user's authentication, mandate and charging message; Use establishment of connection for three layers at WiMAX terminal relaying is provided.
The effect of CSN mainly comprises the following aspects: be WiMAX user conversation distributing IP address; The Internet access is provided; Serve as authentication and authorization charging acting server or authentication and authorization charging server; Carry out strategy and access control based on user contracting data; Support the foundation in tunnel between ASN and the CSN; Support the generation of WiMAX user's ticket and the WiMAX business accounting between the cross operator; Support the foundation in roaming tunnel between the CSN; Support the mobility between the ASN; Support multiple WiMAX professional, such as location-based business, teleservice, multimedia broadcasting and multicast service etc.
The QoS of WiMAX refers to some processes in order to guarantee to provide End-to-end QoS in a network that a plurality of ISPs are arranged and to define.A user can be related with many Business Streams, and these Business Streams can have different QoS attributes, can think that these QoS information are to define in a Subscriber Management System (for example AAA database) or strategic server.Under the QoS of static state service model, the user does not allow to change defined traffic data parameter or Business Stream of dynamic creation.Under dynamic QoS service model, SS or BS can dynamic creations, modification or deletion Business Stream.When a MS registers to the WiMAX network, before the beginning IP transfer of data, can create, permit and activate a whole set of Business Stream according to the acquiescence mode.After a MS successfully is registered in the WiMAX network, must distribute an Anchor SFA to MS.If user's QoS downloads from AAA, then initiate Business Stream ground by SFA and create, permit, activate.May can't create sometimes in ASN or activating service stream, need to determine corresponding the processing this moment according to the negotiation of the qos policy in the ASN and NAP and NSP.
The up-to-date QoS framework of WiMAX NWG standard is as shown in Figure 2:
Being described below of each functional entity in this framework:
MS is mobile subscriber terminal;
SFM is the service flow management entity, is responsible for setting up user traffic flow and traffic flow assignment Radio Resource etc. for this reason, and this functive is present among the ASN;
SFA is service flow authorization person is responsible for to corresponding service flow authorization, and this functive is present among the ASN;
PF is policy functional entity, and for certain user traffic flow provides strategy, this functive is present among the NSP, in roaming scence, will have Visited PF and Home PF;
Aaa server provides the system of authentication, mandate and billing of services, is responsible for preserving user's QoSprofile and relevant policing rule;
AF is the application service functional entity, and directly by application layer protocol connected reference AF, it initiatively is that the user creates Business Stream that AF will notify PF to user terminal SS, and this functive is present among the NSP.
When ASN can't create or activating service stream time, need to determine corresponding processing according to the negotiation of the qos policy in the ASN and NAP and NSP.SFM logic entity among the ASN is responsible for creating, is permitted, activates, revises and the deletion Business Stream.It is comprised of license control (AC) function and related local assistance information.The function of AC is to judge according to existing Radio Resource and local resource situation whether a new Business Stream allows to create.
Fig. 3 is that SFA triggers the flow chart of setting up Business Stream in the prior art.(1) RR_Req wherein: resource reservation request, (6) RR_Rsp: resource reservation response, and (8) RR_Ack: resource reservation is confirmed to be to set up the QoS passage, i.e. QoS Business Stream, transmission QoS parameter; (2) Path_Reg_Req: the data channel registration request, (5) Path_Reg_Rsp: data channel registration response and (7) Path_Reg_Ac k: the data channel accreditation verification is to set up data channel; (3) DSA/DSC Request: dynamic service increase/dynamic service is revised request, (4) DSA/DSC: it is mutual that dynamic service increase/dynamic service modification response is used for finishing space interface signaling.But as can be seen from the figure, finish prior to (8) (7), and namely data channel confirms at last that prior to the QoS traffic flow path (8) finish before.When need to determining according to the negotiation of the qos policy in the ASN and NAP and NSP corresponding the processing, the feedback information of negotiation can't obtain confirming.
In upper figure, (7) Path_Reg_Ack finishes prior to (8) RR_Ack, and namely data channel (7) confirms at last that prior to the QoS traffic flow path (8) finish before, has limited the effect of RR_Rsp.Prior art defines in (1) RR_Req can carry " Reduced Resources ", is used for allowing to reduce interface-free resources, plays the effect of the QoS ability of consulting with Anchor SFA; Can take back the SFA to Anchor by " the QoS Parameters " (6) RR_Rsp from the negotiation return value of eating dishes without rice or wine to come, finally be confirmed by (8) RR_Ack again, indicate the negotiation result to SFM by (7) Path_Reg_Ack.
(7) Path_Reg_Ack does not wait until that the message of (8) RR_Ack just sends, so that (8) RR_Ack is nonsensical on the not impact of whole flow process.
QoS ultimate authority functional entity can't be reduced the processing of holding consultation to QoS Business Stream attribute (profile) in the prior art, finally determines whether to allow to reduce.

Embodiment
The first embodiment provided by the invention is the method for building up of QoS Business Stream among a kind of WiMAX, and method flow comprises as shown in Figure 4:
Step 101: at first Anchor SFA receives user's QoS Business Stream attribute, and Anchor SFA is placed on corresponding QoS Business Stream attribute and sends to Serving SFA in the RR_Req message, is used for request and sets up Business Stream.
Step 102:Serving SFA obtains QoS Business Stream property content according to resolving from the RR_Req message that Anchor SFA receives, send Path_Reg_Req message to SFM and be used for request and set up data channel, the QoS Business Stream property content of receiving of user among the described RR_Req is placed among the described Path_Reg_Req sends SFM to simultaneously.
After step 103:SFM receives described Path_Reg_Req message, judge whether to admit this QoS traffic request according to the interface-free resources that has among the QoS Business Stream property content of carrying in the described Path_Reg_Req message and the SFM.
Step 104: if SFM admits this QoS traffic request, then send DSA/DSCRequest message to MS, request is set up and is eated dishes without rice or wine to connect.
Step 105:MS is after the request of receiving SFM, need to confirm whether MS has the ability to set up corresponding QoS Business Stream for the user, if MS sets up corresponding QoS Business Stream and need to carry out at QoS Business Stream attribute in the situation of resource reduction judge having the ability for the user, resource is reduced judged result be placed on DSA/DSC Response and send to SFM.
Step 106:SFM will reduce negotiation result for the user sets up QoS Business Stream attribute, comprise described resource reduction judged result etc., be carried on Path_Reg_Rsp and send to Serving SFA.
Step 107:Serving SFA is carried on described QoS Business Stream attribute reduction negotiation result and sends to Anchor SFA in the RR_Rsp message.
Step 108: when Anchor SFA is not QoS ultimate authority functional entity, Anchor SFA reduces result feedback to other QoS ultimate authority functional entitys in the network with the QoS Business Stream attribute that SFM and the MS that eats dishes without rice or wine consult to obtain, and obtaining the whether authorized feedback result of other QoS ultimate authority functional entity ruling, Anchor SFA will whether authorized feedback result is placed on feeds back to Serving SFA among the RR_Ack.When Anchor SFA is QoS ultimate authority functional entity, whether accepts this QoS Business Stream attribute by Anchor SFA ruling and reduce the result, and court verdict (namely whether authorized feedback result) is placed on feeds back to Serving SFA among the RR_Ack.QoS ultimate authority functional entity can be PCRF (Policy Control and Charging Rules Function), is used for: policy control decision-making and based on the control of flow based charging.
Step 109:Serving SFA receives the reduction result among the RR_Ack, if being " Success ", the reduction Authorization result namely agrees to reduce, then Serving SFA transmission Path_Reg_Ack will agree that the result who reduces sends SFM, SFM finally reduces negotiation result with this " Success " as QoS Business Stream attribute, and discharge the resource of being reduced with this, and then with result feedback to MS, set up the data path of eating dishes without rice or wine and connect.If being " Failure ", the reduction Authorization result among the RR_Ack namely disagrees with reduction, then ServingSFA transmission Path_Reg_Ack will disagree with that the result of reduction sends SFM, SFM finally reduces negotiation result with this " Failure " as QoS Business Stream attribute, and discharge Data Path resource with this, again with result feedback to MS, QoS reduces and consults unsuccessfully, will not set up the data path of eating dishes without rice or wine and connect.
In said process, if MS is in non-roaming state, then Anchor SFA can replace the function that ServingSFA finishes, and is exactly the non-existent situation of Serving SFA, and this moment, Anchor SFA directly sent to SFM with court verdict.
In order to realize the scheme in above-described embodiment, can carry out on the basis of existing technology following modification:
In Path_Reg_Ack and RR_Ack, increase and carry the whether authorized feedback result that the return value of reducing operation is the ruling of QoS ultimate authority functional entity.
Adjust the order of Path_Reg_Ack and two message of RR_Ack, described Serving SFA sent Path_Reg_Ack to SFM again after Anchor SFA issued Serving SFA with described RR_Ack message, like this so that MS, SFM, SFA can according to the result after the return value license confirmation of reducing operation, activate or the deleting bearing resource.
Concrete scheme is as follows:
It is as follows to increase " Result " in (8) RR_Ack:
It is as follows to increase " Reduced Resource Result " in (7) Path_Req_Ack:
" Result " is defined as follows:
In the technical scheme that the embodiment of the invention provides, when user's QoS Business Stream attribute need to be reduced, SFM will reduce negotiation result with the QoS Business Stream attribute that the user consults and report Anchor SFA, whether authorize described QoS Business Stream attribute to reduce negotiation result and the judgement situation is fed back to SFM by adjudicating as the Anchor SFA of QoS ultimate authority functional entity or other QoS ultimate authority functional entitys, carry out subsequent treatment by described SFM according to described judgement situation, avoided like this in the prior art in the situation that has QoS Business Stream attribute to reduce, the QoS ultimate authority functional entity of network side does not participate in the negotiation that QoS Business Stream attribute is reduced, it can't finally determine whether to allow the defective of reducing, guaranteed that QoS ultimate authority functional entity can to the control of Internet resources, be convenient to network resource management.
Second embodiment of the invention also provides the method for building up of QoS Business Stream among the another kind of WiMAX except above-mentioned method, can adopt RR_REQ message to carry the scheme that can reduce information.
QoS ultimate authority functional entity (such as Anchor SFA) determines that it allows the QoS Business Stream attribute of reducing, and in the qos parameter that RR_Req message is carried, for wherein one or more qos parameters or whole qos parameters, increasing is QoS information accordingly, whether as comprise: allowing to reduce and further can comprise the scope that its QoS Business Stream attribute that allows is reduced, also can be that the reduction scope of directly carrying its permission gets final product.Set up in network in the Business Stream, each carries out entity according to the resource situation of self, with reference to the reduction scope that the QoS that receives allows, sets up in allowed limits Business Stream.
The QoS information that increases in the description of each QoS attribute comprises the following information that is not limited to:
1. whether this QoS attribute allows to reduce;
2. if allow to reduce, how many maximum qos values that this QoS attribute allows is;
3. if allow to reduce, how many minimum qos values that this QoS attribute allows is;
4. if do not allow to reduce, how many this QoS property values is.
When the situation of reducing when QoS Business Stream attribute occurs, follow the QoS information of carrying in the described RR_Req message by SFM and reduce judgement, and determine that with this QoS Business Stream attribute finally reduces negotiation result.After reduction is finished, will reduce finally that negotiation result is placed on Path_Reg_Rsp and RR_Rsp feeds back to Anchor SFA.The specific embodiments method flow comprises as shown in Figure 5:
Step 201: at first Anchor SFA receives the QoS Business Stream attribute that the definite permission of QoS ultimate authority functional entity is reduced, the QoS Business Stream attribute that Anchor SFA allow to reduce QoS ultimate authority functional entity (that is: indication allows the scope that QoS Business Stream attribute is reduced) is carried in the qos parameter of RR_Req and sends to Serving SFA, is used for request and sets up Business Stream.
In the embodiment of the invention, described QoS ultimate authority functional entity can be exactly described AnchorSFA, also can be other network entity, such as PCRF, AAA Server etc.If Anchor SFA oneself is exactly QoS ultimate authority functional entity, then Anchor SFA judges that after receiving user's QoS Business Stream attribute which QoS Business Stream attribute can be reduced and determines its reduction scope, described reduction information is carried in the qos parameter of RR_Req and sends to Serving SFA, be used for request and set up Business Stream.
Step 202:Serving SFA obtains QoS Business Stream property content according to resolving from the RR_Req message that Anchor SFA receives, send Path_Reg_Req message to SFM and be used for asking to set up data channel, allow the QoS Business Stream property content of reduction to be carried in the described Path_Reg_Req message QoS ultimate authority functional entity among the RR_Req simultaneously and send SFM to.
After step 203:SFM receives described Path_Reg_Req message, judge whether to admit this QoS traffic request according to the interface-free resources that has among the QoS Business Stream attribute that carries in the described Path_Reg_Req message and the SFM.
Step 204: if SFM admits this QoS traffic request, then send DSA/DSCRequest to MS, request is set up and is eated dishes without rice or wine to connect.
Step 205:MS need to confirm whether MS has the ability as the user sets up corresponding QoS Business Stream, needs at QoS Business Stream attribute in the situation of resource reduction after the request of receiving SFM, will reduce judged result and be placed on DSA/DSC Response and send to SFM.
Step 206:SFM will follow the QoS information of carrying in the described RR_Req message and reduce judgement, for the user sets up the final reduction negotiation result (namely according to determine QoS Business Stream attribute finally reduce negotiation result) of QoS Business Stream attribute, and with Path_Reg_Rsp determined QoS Business Stream attribute is finally reduced negotiation result and send to Serving SFA.
Step 207:Serving SFA finally reduces negotiation result with described QoS Business Stream attribute and sends to Anchor SFA with RR_Rsp.
Step 208:Serving SFA returns Path_Reg_Ack message to SFM.
Step 209:Anchor SFA returns RR_Ack message to Serving SFA.
Follow-up Path_Reg_Ack message can be identical with scheme of the prior art with RR_Ack message, also can and carry out order adjustment according to the new return value of other increase in demand.
The QoS Business Stream attribute that SFM reduces according to the permission that QoS ultimate authority functional entity is determined determines that QoS Business Stream attribute finally reduces negotiation result.According to such mandate feedback mechanism, so that when user's QoS resource need to be reduced, after SFM and the negotiation of QoS ultimate authority functional entity, the Authorization result of consulting is fed back to SFM, finally determine whether to reduce and the reduction scope, and the QoS Business Stream carried out operational processes, and guaranteed that QoS ultimate authority functional entity can control whether allowing to reduce, be convenient to network resource management.
