Description

Business datum method for stream processing and device
Technical field
The present invention relates to the communications field, in particular to a kind of business datum method for stream processing and device.
Background technology
Third generation partner program (3rd Generation Partnership Project; Abbreviate 3GPP as) grouping system (the Evolved Packet System of evolution; Abbreviate EPS as) by Universal Terrestrial Radio Access Network (the Evolved Universal Terrestrial Radio Access Network of evolution; Abbreviate E-UTRAN as), mobile management unit (Mobility Management Entity; Abbreviate MME as), gateway (Serving Gateway; Abbreviate S-GW as), grouped data network gateway (Packet Data Network Gateway abbreviates P-GW as), home subscriber server (Home Subscriber Server abbreviates HSS as) form.Fig. 1 is the configuration diagram that inserts EPS according to the base station from home under the non-roaming scene of correlation technique (Home evolved NodeB abbreviates HeNB as).Below in conjunction with Fig. 1 the framework of EPS is described.
In Fig. 1, MME is connected with EUTRAN, S-GW and home base-station gateway (HeNB GW), the related work of chains of command such as the processing of responsible mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, between E-UTRAN and P-GW, transmits data, and is responsible for pending datas such as paging are carried out buffer memory; P-GW then is the borde gateway of EPS and packet data network (Packet Data Network abbreviates PDN as) network, and the access of being responsible for PDN reaches functions such as between EPS and PDN, transmitting data.EPS is connected with non-3GPP IP Access Network; Wherein, non-3GPP IP Access Network comprises the non-3GPP IP of trusted Access Network and distrusts non-3GPP IP Access Network that UE inserts P-GW through ePDG; And then the IP operation that provides of access carrier, UE also can insert AAAServer. through ePDG.The interface that each equipment room relates to comprises interfaces such as S1, S2, S5, Gx, and each the concrete equipment and the corresponding relation of each interface see also Fig. 1.
EPS supports the access of H (e) NB, and H (e) NB is a kind of small-sized, lower powered base station, is deployed in indoor places such as family and office, comprises HeNB and HNB.Fig. 2 is in the correlation technique, and UE inserts the Organization Chart of the local route of 3GPP core net through 3GPP H (e) NB.H (e) NB inserts the core net of EPS usually through the fixed network circuit of renting.In order to ensure the safety of access, to introduce security gateway (Security Gateway abbreviates SeGW as) in the core net and shield, the data between H (e) NB and the SeGW will adopt IPSec to encapsulate.H (e) NB can be directly connected to MME, service universal grouping wireless business supporting node (the Serving Gigabyte System Network of core net through the ipsec tunnel of setting up between H (e) NB and the SeGW; Abbreviate SGSN as) and S-GW; Also can be connected to MME, SGSN and S-GW (it is optional that HeNB GW inserts for HeNB, and it is essential that HNB GW inserts for HNB) through H (e) NB GW again.Simultaneously, in order to realize that H (e) NB is managed, introduced network element: base station from home management system (Home (e) NodeB Management System abbreviates H (e) MS as).
At present, a lot of operators pay close attention to fixed network and move fusion (Fixed Mobile Convergence abbreviates FMC as), and study to 3GPP and broadband forum (Broadband Forum abbreviates BBF as) interconnection and interflow.For the scene of user through fixed broadband Access Network (Fixed Broadband Access Network) access mobile core net; Need the service quality (Quality of Service abbreviates QoS as) on the whole transmission path (data can be passed through fixed network and mobile network transmission) of data be guaranteed.But the QoS of the fixed network circuit that H (e) NB inserts normally receives owner and the fixed network operator's of H (e) NB signatory restriction.Therefore, when the common H of 3GPP UE (e) NB inserted 3GPP core net access service, required QoS can not surpass the QoS that contracts of the fixed network circuit that the fixed network operator can provide.Otherwise the QoS of UE access service will can not get ensureing that particularly guaranteed bandwidth (Guaranteed Bitrate abbreviates GBR as) is easy to surpass.Therefore, for the 3GPP network, the QoS aggregate demand that must control the Operational Visit of all UE that insert through H (e) NB is no more than the signatory QoS guarantee of fixed network circuit that this H (e) NB inserts.In the current techniques, carry out alternately, realize that QoS ensures through the broadband policy control architecture in PCRF and the fixed broadband Access Network (Broadband Policy Control Framework abbreviates BPCF as).BPCF is the policy control architecture in the fixed broadband Access Network; To policy charging rule functional entity (Policy and Charging Rules Function; Abbreviate PCRF as) resource request message; BPCF carries out resource and admission control or resource request message is transmitted to the network element (like BNG) of other BBF Access Networks according to the network strategy of fixed broadband Access Network, CAMEL-Subscription-Information etc., carries out resource and admissions control (promptly entrusting other network elements to carry out resource and admissions control) by other network elements again.
Fig. 3 is in the correlation technique under the local route roaming scence, and UE inserts the attachment flow figure of H (e) NB.In this flow process, H-PCRF initiates to set up S9 session and S9 *Session, so as the implementation strategy intercommunication, the QoS of guarantee UE Operational Visit.In this flow process, adopt GPRS Tunnel Protocol (GPRS Tunneling Protocol abbreviates the GTP agreement as) between S-GW and the P-GW.
Step S302:HeNB powers on, and inserts the fixed broadband Access Network.The fixed broadband Access Network is that HeNB distributes local ip address.HeNB and SeGW set up ipsec tunnel; In this process, detect and between HeNB and SeGW, have network address translation (Network Address Translation; NAT); If the local ip address and source user datagram protocol (User Datagram Protocol the abbreviates UDP as) port numbers that exist SeGW then will pass through the HeNB behind the NAT send to HeNB.HeNB and HeMS are mutual, obtain configuration information, comprise the IP address (being the address of HeNB GW or MME) of S1 interface far-end.HeNB is registered to HeNB GW or MME.
Step S304:UE sends Attach Request message to HeNB, carries ID, PDN sign in the message;
Step S306:HeNB sends Attach Request message to HeNB GW, MME, carries ID, PDN sign, HeNB local ip address in the message, alternatively, also carries source udp port number (if detecting NAT);
Step S308:MME sends to S-GW and creates conversation request message, carries ID, PDN sign, HeNB local ip address, alternatively, also carries source udp port number (if detecting NAT);
Step S310:S-GW creates conversation request message to P-GW, carries network identity, the HeNB local ip address of the visited network that ID, PDN sign, S-GW be positioned at, and alternatively, also carries source udp port number (if detecting NAT);
Step S312:P-GW sends the IP-CAN session to home network PCRF (H-PCRF) and sets up Indication message; Carry user's mark, PDN mark, visited network mark, HeNB local ip address; Alternatively, also carry source udp port number (if detecting NAT);
Step S314:H-PCRF inserts through HeNB according to HeNB local ip address and source udp port number judgement UE; And send PCRF according to the network mark of visited network to visited network PCRF (V-PCRF) and initiate gateway control session and set up message, carry HeNB local ip address and optional source udp port number in the message to set up the S9 session;
Step S316:V-PCRF confirms the fixed broadband Access Network according to the HeNB local ip address, and sends PCRF initiation gateway control session to BPCF and set up message to set up S9 *The HeNB local ip address is carried in session in the message, source udp port number;
Step S318:BPCF returns acknowledge message to V-PCRF;
Step S320:V-PCRF returns acknowledge message to H-PCRF;
Step S322:H-PCRF returns the IP-CAN session to P-GW and sets up affirmation;
Step S324:P-GW returns the establishment session response message to S-GW, carries the IP address allocated into UE;
Step S326:S-GW returns the establishment session response message to MME;
Step S328:MME, HeNB GW, HeNB, UE, S-GW are further mutual, set up and to revise wireless access net loaded.
Through above-mentioned flow process; The session of setting up between H-PCRF, V-PCRF and the BPCF; When UE carries out Operational Visit is when needing network to be its Resources allocation; The QoS information of strategy that H-PCRF at first will formulate and charging regulation (Policy and Charging abbreviates PCC as) rule sends to BPCF through V-PCRF, admits control so that the fixed broadband Access Network is carried out.Then, H-PCRF sends to P-GW with the PCC rule of fixed broadband Access Network acceptance.P-GW carries out differentiated services code points (Differentiated Services Code Point according to the PCC rule to the head (being called inner packet header) of the IP of corresponding data flow bag; DSCP) mark; When this business data flow IP bag arrives SeGW; SeGW will carry out the IPSec encapsulation to IP bag, and when encapsulation, according to the DSCP of IP bag (inner packet header) head (being called outside packet header) of the IP bag of IPSec carried out mark.Simultaneously; H-PCRF can number send to the fixed broadband Access Network to the local ip address of HeNB and optional source udp port through V-PCRF, the fixed broadband Access Network according to the local ip address of HeNB and optional source udp port number to filtering from the data of 3GPP core net.If can match corresponding IP bag, prove that then the business of this IP bag is controlled through admitting, thereby carrying out packet according to the DSCP of this IP packet header again, transmitted the fixed broadband Access Network.
Yet the prerequisite of such scheme is the intercommunication of home network support and fixed broadband Access Network, comprises the S9 session foundation that H-PCRF initiates.If when H-PCRF did not support the intercommunication with the fixed broadband Access Network, H-PCRF can not set up the S9 session with V-PCRF, also can not carry out interactive request and admit and control with BPCF.The PCC rule that can cause H-PCRF to issue to PCEF like this is the result of H-PCRF self decision-making.The PCC rule that PCEF issues according to H-PCRF is carried out the DSCP mark to the IP packet header of business data flow.When these business data flows arrived SeGW, SeGW did not know that also these business datums admit control without the fixed broadband Access Network, so still according to the DSCP in outside packet header of DSCP marked copies IPSec in inner packet header.If these data arrives fixed broadband Access Networks, same fixed broadband Access Network can not distinguished these business data flows yet and whether admit control through the fixed broadband Access Network.
Although in the prior art, can provide local ip address and the source udp port of HeNB to let the fixed broadband Access Network filter IP to the fixed broadband Access Network through PCRF and wrap and confirm whether through admitting control.But encapsulate because all IP bags that insert the UE of same HeNB all pass through same ipsec tunnel, see from the angle of fixed broadband Access Network that therefore the IP that it can't distinguish different UEs wraps.As long as wherein certain UE admits control through the fixed broadband Access Network; The 3GPP core net will provide HeNB local ip address and source udp port number alternatively to the fixed broadband Access Network so, and the IP of other UE bag broadband access network that all can be fixed is thought through admitting control like this.
Thereby, do not have to seize other resources for those through the business data flow of admittance control through admitting the business datum of controlling UE to fail to be convened for lack of a quorum, cause at present whole fixing to move fusion (Fixed-Mobile Covergence, FMC) failure of policy control mechanism.
Through the scene that HNB inserts EPC, there is similar problem for UE equally.
Seize other through admitting the resource of the business data flow of controlling to having in the correlation technique, cause the problem of the failure of present whole FMC policy control mechanism, do not propose effective solution at present as yet through admitting the business datum of controlling UE to fail to be convened for lack of a quorum.

The existing business datum method for stream processing that advances the embodiment of the invention and provide with specific embodiment describes.
Embodiment one
Fig. 5 inserts the attachment flow figure under 3GPP roaming scence core net, the local route for UE of the present invention through H (e) NB.Adopt the GTP agreement among Fig. 5 between S-GW and the P-GW.Home network is supported the policy control intercommunication with the fixed broadband Access Network.
Step S502:HeNB powers on, and inserts the fixed broadband Access Network.The fixed broadband Access Network is that HeNB distributes local ip address.HeNB and SeGW set up ipsec tunnel; In this process, detect and between HeNB and SeGW, have network address translation (Network Address Translation; NAT); If the local ip address and source user datagram protocol (User Datagram Protocol the abbreviates UDP as) port numbers that exist SeGW then will pass through the HeNB behind the NAT send to HeNB.HeNB and HeMS are mutual, obtain configuration information, comprise the IP address (being the address of HeNB GW or MME) of S1 interface far-end.HeNB is registered to HeNB GW or MME.
Step S504:UE sends Attach Request message to HeNB, carries ID, PDN sign in the message;
Step S506:HeNB sends Attach Request message to HeNB GW, MME, carries ID, PDN sign, HeNB local ip address in the message, alternatively, also carries source udp port number (if detecting NAT);
Step S508:MME sends to S-GW and creates conversation request message, carries ID, PDN sign, HeNB local ip address, alternatively, also carries source udp port number (if detecting NAT);
Step S510:S-GW creates conversation request message to P-GW, carries network identity, the HeNB local ip address of the visited network that ID, PDN sign, S-GW be positioned at, and alternatively, also carries source udp port number (if detecting NAT);
Step S512:P-GW sends the IP-CAN session to H-PCRF and sets up Indication message; Carrying ID, PDN sign, visited network sign, HeNB local ip address, P-GW is the UE IP address allocated; Alternatively, also carry source udp port number (if detecting NAT);
Step S514:H-PCRF inserts through HeNB according to HeNB local ip address and source udp port number judgement UE; And send PCRF according to the network mark of visited network to V-PCRF and initiate gateway control session and set up message, carry HeNB local ip address and optional source udp port number in the message to set up the S9 session;
Step S516:V-PCRF confirms the fixed broadband Access Network according to the HeNB local ip address, and sends PCRF initiation gateway control session to BPCF and set up message to set up S9 *The HeNB local ip address is carried in session in the message, source udp port number;
Step S518:BPCF returns acknowledge message to V-PCRF;
Step S520:V-PCRF returns acknowledge message to H-PCRF;
Step S522:PCRF returns the IP-CAN session to P-GW and sets up acknowledge message, carries the policy control intercommunication indication of supporting with the fixed broadband Access Network in the message.
Step S524:P-GW returns the establishment session response message to S-GW, carries the policy control intercommunication indication of supporting with the fixed broadband Access Network in the message, UE IP address.
Step S526:S-GW returns the establishment session response message to MME, carries the policy control intercommunication indication of supporting with the fixed broadband Access Network in the message, UE IP address.
Step S528:MME, HeNB GW, HeNB, UE, S-GW are further mutual, set up and to revise wireless access net loaded.In this process, MME also policy control intercommunication indication, the UE IP address notification of handlebar support and fixed broadband Access Network gives HeNB GW (if existence), HeNB.The message that wherein mails to HeNB will be passed through SeGW, and carry out the IPSec encapsulation by SeGW.
Through above-mentioned flow process; The session of setting up between H-PCRF, V-PCRF and the BPCF; When UE needs network to be its Resources allocation through PDN connection the carrying out Operational Visit of setting up; H-PCRF at first sends to BPCF with the QoS information of the PCC rule of formulating, and admits control so that the fixed broadband Access Network is carried out.Then, H-PCRF sends to PCEF with the PCC rule of fixed broadband Access Network acceptance.
Downlink data for business data flow: P-GW (or strategy and charge execution function (Policy and Charging Enforcement Function; Abbreviate PCEF as)) according to the PCC rule head of the IP of corresponding business data flow bag is carried out sending to S-GW behind the mark of DSCP;, will further transmit S-GW after receiving the IP bag to HeNB GW (if existence) or HNB; This moment, S-GW judged that according to the support that in step S524, obtains and the policy control intercommunication indication of fixed broadband Access Network the business data flow that this PDN is connected is to admit control through the fixed broadband Access Network, so the head that wraps at the IP that sends to H (e) NB GW or H (e) NB of S-GW carries out and the IP that receives wraps identical DSCP mark.If S-GW obtains to support the policy control intercommunication with the fixed broadband Access Network to indicate in step S524; Then S-GW will carry out DSCP mark different and the IP packet header of receiving to the head of the IP bag of H (e) NB GW or H (e) NB transmission to S-GW; Promptly the head that the IP that sends wraps is carried out the DSCP mark again based on local policy; Especially, the DSCP of mark lower priority.
According to the indication of supporting to control intercommunication with the fixed broadband access network policy; S-GW can judge that this PDN that UE sets up connects network support and the fixed broadband access network policy control intercommunication that selected P-GW is positioned at; Be that S-GW judges that with it be to support and fixed broadband access network policy control intercommunication at the network of intercommunication just; The business data flow of this PDN connection all is to admit control through the fixed broadband access network resources like this; If do not receive this indication, be not support and fixed broadband access network policy control intercommunication that the business data flow of this PDN connection is all admitted control through the fixed broadband access network resources so just then at the network of intercommunication with S-GW.
As these IP bag processes SeGW; SeGW carries out IPSec when encapsulation and carries out the copy of DSCP according to prior art; When further the IP bag arrives the fixed broadband Access Network; The fixed broadband Access Network is distinguished according to the IP packet header of IPSec and is treated, thereby, can not seize other resources without the IP bag of admitting the control business data flow through the business data flow of admittance control.
S-GW can also judge that PDN connects network under the selected P-GW and whether supports the policy control intercommunication with the fixed broadband Access Network through the mode of configuration in addition.Concrete, for example:
(1) S-GW judges the network under it according to the address of P-GW; And then judge whether this network supports the policy control intercommunication with the fixed broadband Access Network, thereby judge whether the business data flow that this PDN connects admits control through the fixed broadband access network resources;
(2) S-GW is according to the network under the UE IP address judgement P-GW of P-GW distribution; And then judge whether this network supports the policy control intercommunication with the fixed broadband Access Network, thereby judge whether the business data flow that this PDN connects admits control (promptly whether admitting control through the fixed broadband access network resources from the business data flow of this P-GW or network) through the fixed broadband access network resources.If have HeNB GW in the network, so also can on HeNB GW, realize above-mentioned functions.HeNBGW judges that according to the support that in step S528, obtains and the policy control intercommunication indication of fixed broadband Access Network the business data flow that this PDN is connected is to admit control through the fixed broadband Access Network, so HeNB GW carries out and the identical DSCP mark of receiving of IP bag at the head of the IP bag that sends to H (e) NB.If HeNB GW obtains to support the policy control intercommunication with the fixed broadband Access Network to indicate in step S528; Then HeNB GW will be different from the DSCP mark of the IP packet header of receiving to H (e) NB GW to the head of the IP of H (e) NB transmission bag; Promptly the head that the IP that sends wraps is carried out the DSCP mark again based on local policy; Especially, the DSCP of mark lower priority.As IP bag process SeGW; SeGW carries out IPSec when encapsulation and carries out the copy of DSCP according to prior art; When further the IP bag arrives the fixed broadband Access Network; The fixed broadband Access Network is distinguished according to the IP packet header of IPSec and is treated, thereby without admitting the control business data flow can not seize other through admitting the resource of the business data flow of controlling.
HeNB GW also can judge that PDN connects network under the selected P-GW and whether supports the policy control intercommunication with the fixed broadband Access Network through configuration mode in addition.The network under the P-GW is judged in the UE IP address of distributing according to P-GW like HeNB GW; And then judge whether this network supports the policy control intercommunication with the fixed broadband Access Network, thereby judge whether the business data flow that this PDN connects admits control (promptly whether admitting control through the fixed broadband access network resources from the business data flow of this P-GW or network) through the fixed broadband access network resources.
Same similarly function also can realize on SeGW.Similar with the implementation of above-mentioned HeNB GW; SeGW judges that according to the support in the message of intercepting and capturing at step S528 and the policy control intercommunication indication of fixed broadband Access Network the business data flow that this PDN is connected is to admit control through the fixed broadband Access Network; Therefore SeGW is when carrying out the IPSec encapsulation, and the DSCP marked copies of the head of IP bag is to the external IP packet header of IPSec.If SeGW GW obtains the policy control intercommunication indication of support and fixed broadband Access Network in the message that step S528 intercepts and captures; Then SeGW will carry out mark (the DSCP mark in external IP packet header that is IPSec is different with the DSCP in inner IP packet header) to the external IP packet header of IPSec according to local policy, and send to HeNB.Like this, when packet arrived the fixed broadband Access Network, the fixed broadband Access Network was distinguished according to IPSec IP packet header and is treated.Thereby, without admitting the control business data flow can not seize other through admitting the resource of the business data flow of controlling.
SeGW can also judge that PDN connects network under the selected P-GW and whether supports the policy control intercommunication with the fixed broadband Access Network through configuration mode in addition.The network under the P-GW is judged in the UE IP address of distributing according to the P-GW that carries in the message of intercepting and capturing among the step S528 like SeGW; And then judge whether this network supports the policy control intercommunication with the fixed broadband Access Network, thereby judge whether the business data flow that this PDN connects admits control (promptly whether admitting control through the fixed broadband access network resources from the business data flow of this P-GW or network) through the fixed broadband access network resources.
For upstream data: if HeNB is based on Reflective mechanism of the prior art upstream is carried out upstream DSCP mark.Do not carry out the IP newspaper of admitting control for those, because corresponding downlink data stream has been carried out the mark again of DSCP by S-GW, therefore can correct mark upstream according to existing Reflective.If HeNB is the DSCP mark that carries out upstream according to the mapping relations of configuration QoS and DSCP; HeNB will carry out the DSCP mark according to whether in step S528, receiving to support to indicate with the policy control intercommunication of fixed broadband Access Network so: if do not receive; Then HeNB will no longer come the DSCP in mark upstream IP packet header according to the mapping relations of QoS and DSCP; But the external IP packet header of IPSec is carried out and the inner different DSCP mark in IP packet header, promptly the DSCP mark is carried out in the IP packet header of IPSec again, especially according to local policy; It is labeled as the DSCP of lower priority, perhaps carries out the DSCP mark according to Reflective mechanism.If receive, then HeNB is according to the mapping relations of QoS and DSCP, and the up QoS of this business data flow correspondence that issues according to core net comes the DSCP in mark upstream IP packet header.If HeNB is the DSCP mark that carries out upstream according to the mapping relations of QoS and the DSCP of configuration, HeNB can also judge whether business data flow carried out admittance and control according to the IP address of UE.If do not have; Then HeNB will no longer come the DSCP in mark upstream IP packet header according to the mapping relations of QoS that disposes and DSCP; But the external IP packet header of IPSec is carried out and the inner different DSCP mark in IP packet header, promptly the DSCP mark is carried out in the IP packet header of IPSec again, especially according to local policy; It is labeled as the DSCP of lower priority, perhaps carries out the DSCP mark according to Reflective mechanism.If have, then HeNB is according to the QoS and the mapping relations of DSCP of configuration, and the up QoS of this business data flow correspondence that issues according to core net comes the DSCP in mark upstream IP packet header.If HeNB is the DSCP mark that carries out upstream according to the mapping relations of QoS and the DSCP of configuration, HeNB can also judge whether business data flow carried out admittance and control according to following method.When at first HeNB receives downlink data; Whether the DSCP mark in downstream IP packet header of judging this business data flow according to QoS and the mapping relations of DSCP of configuration is consistent with the corresponding DSCP that descending QoS was mapped to of this business data flow: as if unanimity; Network element (like the S-GW among the present invention, HeNB GW or SeGW) before then showing did not carry out the mark again to the DSCP of downstream IP bag, and promptly this business data flow carried out admitting control.At this moment, HeNB is according to QoS and the mapping relations of DSCP of configuration, and the up QoS that issues according to core net carries out DSCP mark that up IP wraps.If inconsistent, the network element (like the S-GW among the present invention, HeNB GW or SeGW) before then showing carried out the mark again of the DSCP of downstream IP bag, and promptly this business data flow did not carry out admitting control.At this moment, HNB is no longer according to QoS and the mapping relations of DSCP of configuration, and the up QoS that issues according to core net carries out the DSCP mark of upstream.But the external IP packet header of IPSec is carried out and the inner different DSCP mark in IP packet header; Promptly the DSCP mark is carried out in the IP packet header of IPSec again according to local policy; Especially, it is labeled as the DSCP of lower priority, perhaps carries out the DSCP mark according to Reflective mechanism.
H (e) NB also comprises HNB by HeNB except that comprising.Insert the scene of EPC for UE through HNB, implementation is similarly, below only simply describes.
For downlink data, its treatment step is following:
(1) whether S-GW, SGSN, HNB GW or SeGW according to carrying in the message support to judge with the policy control intercommunication indication of fixed broadband Access Network whether the business data flow that this PDN is connected is controlled through the admittance of fixed broadband Access Network; And corresponding D SCP mark is carried out in the IP packet header of downstream data flow, and (if support, the IP bag of transmission adopts and the identical DSCP mark of receiving of IP bag; If do not support, the IP bag that then sends adopts and the different DSCP mark of receiving of IP bag, promptly according to local policy the IP bag that sends is carried out the DSCP mark again);
(2) (S-GW is according to the address of UE IP address or P-GW according to configuration for S-GW, SGSN, HNB GW or SeGW; SGSN, HNB GW and SeGW are according to UE IP address) judge that PDN is connected network under the selected P-GW and whether supports the policy control intercommunication with the fixed broadband Access Network; Thereby judge whether the business data flow that this PDN connects is controlled through the admittance of fixed broadband Access Network; And corresponding D SCP mark is carried out in the IP packet header of downstream data flow, and (if support, the IP bag of transmission adopts and the identical DSCP mark of receiving of IP bag; If do not support, the IP bag that then sends adopts and the different DSCP mark of receiving of IP bag, promptly according to local policy the IP bag that sends is carried out the DSCP mark again).
For upstream, HNB can adopt the identical realization mechanism with HeNB, repeats no more here.
Embodiment two
Fig. 6 inserts the PDN connection request flow chart under 3GPP roaming scence core net, the local route for UE of the present invention through H (e) NB.Adopt the GTP agreement among Fig. 6 between S-GW and the P-GW.Home network is supported the policy control intercommunication with the fixed broadband Access Network.
Step S602:UE sends PDN connection request message to MME, and H (e) NB adds H (e) NB local ip address and optional UPD port numbers in message.
Step S604:MME sends to S-GW and creates conversation request message, carries ID, PDN sign, HeNB local ip address, alternatively, also carries source udp port number (if detecting NAT);
Step S606:S-GW creates conversation request message to P-GW, carries network mark, the HeNB local ip address of the visited network that ID, PDN mark, S-GW be positioned at, and alternatively, also carries source udp port number (if detecting NAT);
Step S608:P-GW sends the IP-CAN session to H-PCRF and sets up Indication message; Carrying ID, PDN sign, visited network sign, HeNB local ip address, P-GW is the UE IP address allocated; Alternatively, also carry source udp port number (if detecting NAT);
Step S610:H-PCRF inserts through HeNB according to HeNB local ip address and source udp port number judgement UE; And send PCRF according to the network identity of visited network to V-PCRF and initiate gateway control session and set up message, carry HeNB local ip address and optional source udp port number in the message to set up the S9 session;
Step S612:V-PCRF confirms the fixed broadband Access Network according to the HeNB local ip address, and sends PCRF initiation gateway control session to BPCF and set up message to set up S9 *The HeNB local ip address is carried in session in the message, source udp port number;
Step S614:BPCF returns acknowledge message to V-PCRF;
Step S616:V-PCRF returns acknowledge message to H-PCRF;
Step S618:H-PCRF returns the IP-CAN session to P-GW and sets up affirmation;
Step S620:P-GW returns the establishment session response message to S-GW, carries and supports and the policy control intercommunication indication of fixed broadband Access Network, is the UE IP address allocated;
Step S622:S-GW returns the establishment session response message to MME, carries and supports and the policy control intercommunication indication of fixed broadband Access Network, is the UE IP address allocated;
Step S624:MME, HeNB GW, HeNB, UE, S-GW are further mutual, set up and to revise wireless access net loaded, carry in the above-mentioned message and support and the policy control intercommunication indication of fixed broadband Access Network, are the UE IP address allocated.The message that wherein mails to HeNB will be passed through SeGW, and carry out the IPSec encapsulation by SeGW.
Through above-mentioned flow process; The session of setting up between PCRF and the BPCF; When UE needed network to be its Resources allocation through newly-established PDN connection carrying out Operational Visit, H-PCRF at first sent to BPCF with the QoS information of the PCC rule of formulating, and controls so that the fixed broadband Access Network is carried out to admit.Then, H-PCRF sends to PCEF with the PCC rule of fixed broadband Access Network acceptance.
Downlink data for business data flow: P-GW (or PCEF) carries out the head of the IP of corresponding business data flow bag according to the PCC rule sending to S-GW behind the mark of DSCP;, will further transmit S-GW after receiving the IP bag to HeNB GW (if existence) or HNB; S-GW judges that according to the support that in step S620, obtains and the policy control intercommunication indication of fixed broadband Access Network the IP bag of the business data flow that this PDN is connected is to admit control through the fixed broadband Access Network, so the head that wraps at the IP that sends to H (e) NB GW or H (e) NB of S-GW carries out and the IP that receives wraps identical DSCP mark.If S-GW obtains to support the policy control intercommunication with the fixed broadband Access Network to indicate in step S620; Then S-GW will be different from the DSCP mark of the IP packet header of receiving to S-GW to the head of the IP bag of H (e) NB GW or H (e) NB transmission; Promptly the head that the IP that sends wraps is carried out the DSCP mark again according to this strategy; Especially, the DSCP of mark lower priority.
During enforcement; According to the indication of supporting to control intercommunication with the fixed broadband access network policy; S-GW can judge that this PDN that UE sets up connects network support and the fixed broadband access network policy control intercommunication that selected P-GW is positioned at; Be that S-GW judges that with it be to support and fixed broadband access network policy control intercommunication at the network of intercommunication just; The business data flow of this PDN connection all is to admit control through the fixed broadband access network resources like this; If do not receive this indication, be not support and fixed broadband access network policy control intercommunication that the business data flow of this PDN connection is all admitted control through the fixed broadband access network resources so just then at the network of intercommunication with S-GW.As IP bag process SeGW; SeGW carries out IPSec when encapsulation and carries out the copy of DSCP according to prior art; When further the IP bag arrives the fixed broadband Access Network; The fixed broadband Access Network is distinguished according to the IP packet header of IPSec and is treated, thereby, without admitting the control business data flow can not seize other through admitting the resource of the business data flow of controlling.
S-GW can also judge that PDN connects network under the selected P-GW and whether supports the policy control intercommunication with the fixed broadband Access Network through the mode of configuration in addition.For example:
(1) S-GW judges the network under it according to the address of P-GW; And then judge whether this network supports the policy control intercommunication with the fixed broadband Access Network, thereby judge whether the business data flow that this PDN connects admits control through the fixed broadband access network resources;
(2) S-GW is according to the network under the UE IP address judgement P-GW of P-GW distribution; And then judge whether this network supports the policy control intercommunication with the fixed broadband Access Network, thereby judge whether the business data flow that this PDN connects admits control (promptly whether admitting control through the fixed broadband access network resources from the business data flow of this P-GW or network) through the fixed broadband access network resources.
If have HeNB GW in the network, so also can on HeNB GW, realize above-mentioned functions.HeNB GW judges that according to the support that in step S624, obtains and the policy control intercommunication indication of fixed broadband Access Network the business data flow that this PDN is connected is to admit control through the fixed broadband Access Network, so HeNB GW carries out and the identical DSCP mark of receiving of IP bag at the head of the IP bag that sends to H (e) NB.If HeNB GW obtains to support the policy control intercommunication with the fixed broadband Access Network to indicate in step S624; Then HeNB GW will be different from the DSCP mark of the IP packet header of receiving to H (e) NB GW to the head of the IP of H (e) NB transmission bag; Promptly the head that the IP that sends wraps is carried out the DSCP mark again according to this strategy; Especially, the DSCP of mark lower priority.As IP bag process SeGW; SeGW carries out IPSec when encapsulation and carries out the copy of DSCP according to prior art; When further the IP bag arrives the fixed broadband Access Network; The fixed broadband Access Network is distinguished according to the IP packet header of IPSec and is treated, thereby without admitting the control business data flow can not seize other through admitting the resource of the business data flow of controlling.
HeNB GW can also judge that PDN connects network under the selected P-GW and whether supports the policy control intercommunication with the fixed broadband Access Network through configuration mode in addition.The network under the P-GW is judged in the UE IP address of distributing according to P-GW like HeNB GW; And then judge whether this network supports the policy control intercommunication with the fixed broadband Access Network, thereby judge whether the business data flow that this PDN connects admits control (promptly whether admitting control through the fixed broadband access network resources from the business data flow of this P-GW or network) through the fixed broadband access network resources.
Same similarly function also can realize on SeGW.SeGW judges that according to the support in the message of intercepting and capturing at step S624 and the policy control intercommunication indication of fixed broadband Access Network the business data flow that this PDN is connected is to admit control through the fixed broadband Access Network; Therefore SeGW is when carrying out the IPSec encapsulation, and the DSCP marked copies of the head of IP bag is to the external IP packet header of IPSec.If SeGW does not obtain in the message that step S624 intercepts and captures to support and the policy control intercommunication indication of fixed broadband Access Network that then SeGW will carry out mark to the external IP packet header of IPSec according to local policy, and send to HeNB.Like this, when packet arrived the fixed broadband Access Network, the fixed broadband Access Network was distinguished according to IPSec IP packet header and is treated.Thereby, without admitting the control business data flow can not seize other through admitting the resource of the business data flow of controlling.
SeGW can also judge that PDN connects network under the selected P-GW and whether supports the policy control intercommunication with the fixed broadband Access Network through configuration mode in addition.The network under the P-GW is judged in the UEIP address of distributing according to the P-GW that carries in the message of intercepting and capturing among the step S624 like SeGW; And then judge whether this network supports the policy control intercommunication with the fixed broadband Access Network, thereby judge whether the business data flow that this PDN connects admits control (promptly whether admitting control through the fixed broadband access network resources from the business data flow of this P-GW or network) through the fixed broadband access network resources.
For upstream data: if HeNB is based on Reflective mechanism of the prior art upstream is carried out upstream DSCP mark.Do not carry out the IP newspaper of admitting control for those, because corresponding downlink data stream has been carried out the mark again of DSCP by S-GW, therefore can correct mark upstream according to existing Reflective.If HeNB is the DSCP mark that carries out upstream according to the mapping relations of QoS and the DSCP of configuration; HeNB will carry out the DSCP mark according to whether in step S624, receiving to support to indicate with the policy control intercommunication of fixed broadband Access Network so: if do not receive; Then HeNB will no longer come the DSCP in mark upstream IP packet header according to the mapping relations of QoS and DSCP; But the external IP packet header of IPSec is carried out and the inner different DSCP mark in IP packet header; Promptly the DSCP mark is carried out in the IP packet header of IPSec again according to local policy; Especially, it is labeled as the DSCP of lower priority, perhaps carries out the DSCP mark according to Reflective mechanism.If receive, then HeNB is according to the mapping relations of QoS and DSCP, and the up QoS of this business data flow correspondence that issues according to core net comes the DSCP in mark upstream IP packet header.If HeNB is the DSCP mark that carries out upstream according to the mapping relations of configuration QoS and DSCP, HeNB can also judge whether business data flow carried out admittance and control according to the IP address of UE.If do not have; Then HeNB will no longer come the DSCP in mark upstream IP packet header according to the mapping relations of QoS and DSCP; But the external IP packet header of IPSec is carried out and the inner different DSCP mark in IP packet header, promptly the DSCP mark is carried out in the IP packet header of IPSec again, especially according to local policy; It is labeled as the DSCP of lower priority, perhaps carries out the DSCP mark according to Reflective mechanism.If have, then HeNB is according to the mapping relations of QoS and DSCP, and the up QoS of this business data flow correspondence that issues according to core net comes the DSCP in mark upstream IP packet header.If HeNB is the DSCP mark that carries out upstream according to the mapping relations of QoS and the DSCP of configuration, HeNB can also judge whether business data flow carried out admittance and control according to following method.When at first HeNB receives downlink data; Whether the DSCP mark in downstream IP packet header of judging this business data flow according to QoS and the mapping relations of DSCP of configuration is consistent with the corresponding DSCP that descending QoS was mapped to of this business data flow: as if unanimity; Network element (like the S-GW among the present invention, HeNB GW or SeGW) before then showing did not carry out the mark again to the DSCP of downstream IP bag, and promptly this business data flow carried out admitting control.At this moment, HeNB is according to QoS and the mapping relations of DSCP of configuration, and the up QoS that issues according to core net carries out DSCP mark that up IP wraps.If inconsistent, the network element (like the S-GW among the present invention, HeNB GW or SeGW) before then showing carried out the mark again of the DSCP of downstream IP bag, and promptly this business data flow did not carry out admitting control.At this moment, HNB is no longer according to QoS and the mapping relations of DSCP of configuration, and the up QoS that issues according to core net carries out the DSCP mark of upstream.But the external IP packet header of IPSec is carried out and the inner different DSCP mark in IP packet header; Promptly the DSCP mark is carried out in the IP packet header of IPSec again according to local policy; Especially, it is labeled as the DSCP of lower priority, perhaps carries out the DSCP mark according to Reflective mechanism.
For the scene of UE through HNB access EPC, implementation is similarly, only simply describes below.
