ASN GW, access service network gateway provides convergence and signaling relay function;
HA, Home Agent, home agent provides Mobile IP (Mobile IP, MIP) service;
PF, Policy Function, policing feature is responsible for the strategy decisive function based on the user, and it both can be positioned at ASN also can be positioned at CSN.If be arranged in ASN, then be positioned at the ASN GW at Authenticator (authentication device) and Anchor SFA (Anchor Service Flow Authorization, the mandate of anchor service flow) place, be called Local PF (local PF); If be arranged in CSN, be independent network element then, or be arranged in AAA server.At network design under the scene of PCC (Policy Charging Control, policy and charging control) system, PF is replaced by PCRF (Policy Charging Rule Function, policy charging rule function), is arranged in CSN.
AAA Server (Authentication Authorization Accounting Server, authentication authorized charging server) is responsible for terminal use's authentication and authorization charging.Under the roaming scence, the aaa server in the access zone network is also referred to as AAA proxy (AAA acting server).
The business datum passage of WiMAX system comprises the Datapath of empty port load-supporting, R6 interface (between BS and the ASN GW) and the Interface R4 (between the ASN GW) of R1 interface (between MS and the BS), the MIP tunnel of Interface R3 (between ASN GW and the HA).General data channel is shown in thick line among Fig. 1.When whole data channel overlaps, or Data duplication can carry out at this network element the local exchange of data when the same network element.A plurality of can carry out the network element of local exchange the time when existing, in order to reach optimum efficiency, usually be chosen in from the nearest network element of communication node and carry out local exchange.
The system of the control LS that present embodiment provides (Local Switching, local exchange) as shown in Figure 2, mainly comprises:
Subscribed database is used for preserving the customer service subscription data, and it can be positioned on aaa server or the SPR (Subscription Profile Repository, user-subscribed database).Can in the customer service subscription data, increase LS indication in the embodiment of the invention, be used to indicate related service stream and carry out local exchange.The LS indication here is the local exchange strategy that is kept in the subscribed database.
The LS decision point is used for indicating to judge whether to allow to carry out local exchange according to the LS from subscribed database, if allow, then issues the 2nd LS indication to the LS control point; Otherwise do not carry out local exchange.It can be positioned on the signaling plane network element, for example: on PF, Local PF (local PF) or the PCRF.
The LS control point is used for judging whether to carry out local exchange according to the 2nd LS indication from the LS decision point, or directly carries out local exchange according to the 2nd LS notice related network elements.It is usually located on the data surface network element, for example: be positioned on ASN GW or the BS.
Different according to the scope of application, LS indication can be divided into following a few class: based on the user, based on terminal, service based, based on service flow, location-based or above combination.
Be applicable to all service flow of this user based on user's LS indication.Be applicable to all service flow of this terminal based on the LS indication of terminal.The LS indication of service based is applicable to all service flow that this business comprises.LS indication based on service flow is applicable to this service flow.Location-based LS indication is applicable to the network element of assigned address, can be ASN GW or BS, and expression allows this network element that all service flow that can carry out local exchange are carried out local exchange.
Further, LS indication can be the LS indication based on user+terminal, and when meaning this user and using this terminal, all service flow allow local exchange.LS indication based on user/terminal/business/service flow+position, mean and allow to specify network element that qualified Business Stream is carried out local exchange, for example based on the LS indication of user+position, be the network element that allows assigned address this user's service flow is carried out local exchange.
The method of embodiment of the invention control local exchange comprises:
1, local exchange LS decision point receives the LS indication from subscribed database;
2, described LS decision point judges whether to allow to carry out local exchange according to described LS indication and local policy;
Wherein: if local policy allows the local exchange type in the LS indication, then allow to carry out local exchange; If local policy does not allow the local exchange type in the LS indication, then do not allow to carry out local exchange; Described LS decision point is positioned on the signaling plane network element.
If 3 allow to carry out local exchange, then described LS decision point issues the 2nd LS indication to the LS control point; Otherwise, do not carry out local exchange.
Further, local exchange can be carried out according to the network element that described the 2nd LS indication notice is responsible for the execution local exchange in the LS control point.Perhaps, judge whether to carry out local exchange according to described the 2nd LS indication and local policy, if so, then the responsible network element of carrying out local exchange of notice carries out local exchange, otherwise, do not carry out local exchange, carry out the prior art related procedure.
Embodiment one
The method of embodiment of the invention control local exchange comprises with reference to figure 3:
301, subscribed database issues LS indication to the LS decision point, is specially:
When having trigger condition to occur, subscribed database issues LS indication to the LS decision point, and this indication is the local exchange strategy that is kept in the subscribed database, can be contained in the customer service CAMEL-Subscription-Information.The present invention does not limit the concrete form of this LS indication, here only provide two kinds of feasible forms: 1, represent the local exchange strategy with a complex parameter, be that the LS indication parameter comprises two parts, front portion is used for the type of expression local exchange, be used for to distinguish and to be based on service flow, based on the user, based on the local exchange of terminal, service based, position-based or its combination, rear portion is used for the object that expression allows local exchange, such as service flow sign, user ID, terminal iidentification, service identification, positional information or its combination etc.2, as an independent parameter, when it and other parameters together the time, the expression local exchange strategy that combines, for example: the LS indication is placed on that expression allows this service flow local exchange in SF Info (service flow information) parameter, is placed on all service flow local exchanges that expression among the user profile (files on each of customers) allows this user or terminal, is placed on that expression allows this professional service flow local exchange or allows location-based local exchange with positional information combination expression in the business description information.
Trigger condition can have multiple, receives that such as subscribed database the request message of LS decision point, customer service CAMEL-Subscription-Information in the subscribed database change or operator changes LS strategy etc.
302, the LS decision point is carried out the LS decision-making according to the LS indication from subscribed database.
The LS decision point judges whether to allow local exchange after receiving LS indication.Judge whether to allow local exchange to carry out according to the local policy of LS indication and LS decision point.Here the local policy of said LS decision point refers to the strategy relevant with local exchange that is kept at the LS decision point, and it can be pre-configured in charging that beared information that local exchange strategy on the LS decision point, LS decision point obtain from ASN or service flow information, LS decision point obtain from CSN or QoS control strategy etc. for operator.
When the LS decision point do not have relevant local policy or local policy allow carry out step 301 in the represented local exchange type of LS indication, the local exchange strategy of the subscribed database transmission in the LS that then makes here decision-making and the step 301 is identical; For example: the LS indication that sends when subscribed database is to allow current service stream to carry out local exchange, and then the LS decision point judges and allows current service stream to carry out local exchange.
When LS decision point local policy does not allow to carry out local exchange, the decision-making of then making here is not allow to carry out local exchange.For example: the local exchange strategy that subscribed database provides is to allow to carry out certain type local exchange, but the LS decision point has been learnt before this charging point of current network and has been positioned at CSN (for example HA), and all service flow must be by charging, therefore all service flow must be finished through CSN the collection of charge information, then the LS decision point judges and does not allow to carry out local exchange, and follow-up flow process no longer relates to local exchange.
The represented local exchange type of LS indication in the local policy of LS decision point does not allow carry out step 301, but can allow the less local exchange type of scope in the LS indication, as: allow user's part service flow or the part service flow of terminal to carry out local exchange, the LS that then makes here decision-making is then different from the local exchange strategy that sends of subscribed database in the step 301, only allows the part service flow in the LS indication to carry out local exchange; For example the local exchange strategy that provides of subscribed database is to allow the active user to carry out local exchange, but the LS decision point has been learnt before this some service flow of this user and must have been carried out Lawful Interception by the rear end network element, therefore these monitored service flow can not be carried out local exchange, and then the LS decision point judges and only allows the service flow of this user except the service flow that this part is lawfully intercepted to carry out local exchange.
If 303 LS decision points allow to carry out local exchange, then the LS decision point issues the 2nd LS indication to the LS control point, and expression LS decision point allows to carry out certain type local exchange; If the LS decision point only allows the part service flow to carry out local exchange, then the LS decision point issues to the LS control point to indicate in the 2nd LS indication and allows the part service flow to carry out local exchange.
304, the LS control point judges whether to carry out local exchange according to the 2nd LS indication and LS control point local policy from the LS decision point, and if so, then the responsible data surface network element of carrying out local exchange of notice carries out local exchange.Otherwise carry out the prior art related procedure, repeat no more.Or the data surface network element that the execution local exchange is responsible for according to described the 2nd LS indication notice in the LS control point carries out local exchange.
The local policy at the LS control point of mentioning here refers to the relevant strategy of local exchange of LS control point preservation, includes but not limited to subscriber terminal service flow context, charging or the QoS control strategy etc. that safeguard at the pre-configured local exchange strategy of operator, LS control point.
Embodiment two
In the present embodiment, subscribed database is positioned at aaa server, LS decision point and LS control point all are positioned at Anchor SFA (Anchor Service Flow Authorization, the mandate of anchor service flow) on the ASN GW at place, this ASN GW also is the network element for the Local PF place of dynamic QoS control simultaneously.The LS decision-making that ASN GW carries out and the step of LS control are merged into a control step.Present embodiment is applicable to non-PCC scene, comprises dynamic QoS and non-dynamic QoS.
The method of embodiment of the invention local exchange comprises with reference to figure 4:
401, when the success of terminal networking authentication, aaa server sends Access Accept (access is permitted) message to the ASN GW at Authenticator (authentication device) and Anchor SFA place, carries the LS indication in the message; Described LS indication can be carried in the user signing contract information of Access Accept message.
When perhaps user signing contract information was updated, aaa server sent CoARequest (Change Of Authorization request authorizes the change request) message to this ASN GW, carries the LS indication in the message; LS indicates in the user signing contract information that can carry after upgrading in the CoA Request message; After ASN GW receives CoA request, can return CoA Response message as response to aaa server.
402, ASN GW preserves the user signing contract information of receiving.Then ASN GW judges whether to allow to carry out local exchange according to LS indication and local policy, if do not carry out local exchange, then initiate to preset stream (pre-provision service flow) according to prior art and set up process (if receive be AccessAccept message), perhaps service flow (comprising the dynamic service flow that presets stream and set up) foundation/modification/delete procedure (if receive be CoA message); If determine to carry out local exchange, then initiate the stream that presets of local exchange and set up process, perhaps initiate service flow (comprising the dynamic service flow that presets stream and the set up) foundation/modification/delete procedure of local exchange.If determine to allow the part service flow to carry out local exchange, the stream that presets of then initiating local exchange for the part service flow that allows to carry out local exchange is set up process, perhaps initiates the service flow foundation/modification/delete procedure of local exchange.
Present embodiment is equally applicable to the dynamic service flow foundation/modification process that the terminal in the Dynamic QoS scene is initiated, and aaa server is similar to step and the step 401 that ASN GW issues LS indication, repeats no more; Step 402 is: MS is the foundation of request dynamic service flow/modification at any time, when ASN GW receives the service flow foundation of MS or revises request, judge whether to carry out local exchange, if do not carry out local exchange, then set up or revise response by prior art return service stream; If carry out local exchange, then return with the service flow of LS indication to the data surface network element of carrying out local exchange and set up or the modification response, set up or revise so that the data surface network element is carried out the service flow of local exchange; If allow the part service flow to carry out local exchange, then LS indicates and allows the part service flow to carry out local exchange.
Embodiment three

501, step 401 is similar among this step and the embodiment two, and ASN GW receives from the Access Accept message of aaa server or CoA Request message, wherein carries LS indication, repeats no more.
502, ASN GW sends out authorization requests to PCRF/PF.Be specially:
If PCC scene, then ASN GW sends IP CAN Session to PCRF and sets up request message, this request message can for CCR (Credit Control Request, the credit control request) message of DIAMETER agreement, carry the LS indication of receiving in the step 501 in the message.Perhaps, through any time after the step 501, ASN GW need to initiate IP CAN Session and revise, perhaps receive IP CAN Bear signaling, for example RR Request message is used for request IP CAN Session and revises, and then ASN GW sends IP CAN Session to PCRF and revises request, request message can use the CCR message of DIAMETER agreement, carries the LS indication of receiving in the step 501 in the message.Need to prove, message between ASN GW and the PCRF may need (the PolicyDistribution Function by PDF, the strategy distribution function) transmits being not always the case alternately between the every PCRF of relating in back and the ASNGW, no longer repeat specification.
If PF scene, then ASN GW sends SFA LU (Service FlowAuthorization Location Update to PF, the service flow authorized location is upgraded) request message or RRrequest (Resource Reservation request, resource reservation request) message is carried the LS indication of receiving in the step 501 in the message.
503, PCRF/PF judges whether to allow local exchange according to LS indication and local policy, then return authorization response.Be specially:
If the PCC scene, then PCRF returns IP CAN Session to ASN GW and sets up response or IP CAN Session modification response, and response message can use CCA (CreditControl Answer, the Credit Control Answer) message of DIAMETER agreement.As allow to carry out local exchange, indicate with the 2nd LS in the message; If allow the part service flow to carry out local exchange, the 2nd LS that then carries in the message indicates and allows the part service flow to carry out local exchange; If do not allow, then there is not the 2nd LS indication in the message, carry out the related procedure of prior art.
If the PF scene, then PF sends RR request message (as the response to SFA LU message) or RR response message (as the response to RR request) to ASN GW.As allow to carry out local exchange, indicate with the 2nd LS in the message.If allow the part service flow to carry out local exchange, the 2nd LS that then carries in the message indicates and allows the part service flow to carry out local exchange; If do not allow, then there is not the 2nd LS indication in the message, carry out the related procedure of prior art.
504, ASN GW receives from after the 2nd LS of the PCRF/PF indication, judge whether to carry out local exchange, if, then to Anchor DPF (Anchor Datapath Function, the anchor data path function) the ASN GW at place sends the RR request with the 2nd LS indication, initiates to set up for the carrying of local exchange; Perhaps the ASN GW to Anchor DPF place sends the IP CANBear signaling response of indicating with LS, and for example RR response confirms to set up for the carrying of local exchange.Otherwise, send RR request to the ASN GW at Anchor DPF place by prior art, initiate loading establishing process; Perhaps send RR response to the ASN GW at the Anchor DPF place response as IP CAN Bear signaling by prior art.
Embodiment four

ASN GW sends IP CAN Session to PCRF and sets up request, and request message can use CCR (credit control request, the credit control request) message of DIAMETER agreement.
Perhaps, ASN GW need to initiate IP CAN Session and revise, perhaps receive IP CAN Bear signaling, RR Request message for example, being used for request IP CAN Session revises, then ASN GW sends IP CAN Session to PCRF and revises request, and request message uses the CCR message of DIAMETER agreement.Need to prove that the message between ASN GW and the PCRF may need to transmit by PDF (Policy Distribution Function, strategy distribution function).
602, PCRF obtains user signing contract information from SPR, indicates comprising a LS.
After this step may be triggered by step 601, then be step 601 after, PCRF sends out request message to SPR, SPR sends user signing contract information to PCRF.
This step also may be irrelevant with step 601, occurs in before the step 601 or simultaneously to occur, and then be that SPR initiatively sends user signing contract information to PCRF.
603, PCRF judges whether to allow local exchange, then return authorization response.Be specially:
PCRF returns IP CAN Session to ASN GW and sets up response or IP CAN Session modification response, and response message uses CCA (Credit Control Answer, the Credit Control Answer) message of DIAMETER agreement.Allow to carry out local exchange such as PCRF, indicate with the 2nd LS in the message.If allow the part service flow to carry out local exchange, the 2nd LS that then carries in the message indicates and allows the part service flow to carry out local exchange;
604, ASN GW receives from after the 2nd LS of the PCRF indication, judge whether to carry out local exchange, if, then to Anchor DPF (Anchor Datapath Function, the anchor data path function) the ASN GW at place sends the RR request with the 2nd LS indication, initiates to set up for the carrying of local exchange; Perhaps the ASN GW to Anchor DPF place sends the IP CANBear signaling response of indicating with LS, and for example RR response confirms to set up for the carrying of local exchange.Otherwise, send RR request to the ASN GW at Anchor DPF place by prior art, initiate carrying foundation, perhaps send RR response to the ASN GW at Anchor DPF place by prior art, confirm carrying foundation.
