Description

Business data flow processing method and processing device
Technical field
The present invention relates to the communications field, in particular to a kind of business data flow processing method and processing device.
Background technology
Third generation partner program (3rd Generation Partnership Project's, referred to as 3GPP) drills The grouping system (Evolved Packet System, referred to as EPS) entered is by the Universal Terrestrial Radio Access Network of evolution (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), mobile management list First (Mobility Management Entity, referred to as MME), gateway (Serving Gateway, referred to as S- GW), grouped data network gateway (Packet Data Network Gateway, referred to as P-GW), home subscriber server (Home Subscriber Server, referred to as HSS) is constituted.Fig. 1 is the family expenses under the non-roaming scene according to correlation technique EPS configuration diagram is accessed in base station (Home evolved NodeB, referred to as HeNB).With reference to frameworks of the Fig. 1 to EPS Illustrate.
In Fig. 1, MME is connected with EUTRAN, S-GW and home base-station gateway (HeNB GW), responsible mobile management, The related work of the chain of command such as the processing of Non-Access Stratum signaling and the management of user's mobile management context；S-GW is and E- Accessing gateway equipment connected UTRAN, forwards data, and be responsible for entering the pending datas such as paging between E-UTRAN and P-GW Row caching；P-GW is then EPS and packet data network (Packet Data Network, referred to as PDN) network border net Close, be responsible for PDN access and the functions such as data are forwarded between EPS and PDN.EPS is connected with non-3 gpp IP access networks, wherein, Non-3 gpp IP access networks include trusted non-3 gpp IP access networks and distrust non-3 gpp IP access networks, and UE is connect by ePDG Enter P-GW, and then the IP operation that access carrier is provided, UE can also access AAAServer. through ePDG.What each equipment room was related to The interface interface such as including S1, S2, S5, Gx, specific each equipment and the corresponding relation of each interface refer to Fig. 1.
EPS supports H (e) NB access, and H (e) NB are a kind of small-sized, low-power base stations, are deployed in family and office Deng indoor place, including HeNB and HNB.Fig. 2 is in correlation technique, UE passes through the family that 3GPP H (e) NB access 3GPP core nets The Organization Chart of township's route.H (e) NB generally access EPS core net by the fixed network circuit of rental.In order to ensure the peace of access Entirely, security gateway (Security Gateway, referred to as SeGW) is introduced in core net to be shielded, between H (e) NB and SeGW Data will be packaged using IPSec.H (e) NB can directly be connected by the ipsec tunnel set up between H (e) NB and SeGW Be connected to the MME of core net, service universal grouping wireless business supporting node (Serving Gigabyte System Network, Referred to as SGSN) and S-GW, can also being connected to MME, SGSN and S-GW by H (e) NB GW again, (HeNB GW connect for HeNB It is optional to enter, and HNB GW are essential for HNB accesses).Meanwhile, H (e) NB are managed in order to realize, net is introduced Member：Home eNodeB Management System (Home (e) NodeB Management System, referred to as H (e) MS).
At present, many operator's concern fixed network mobile fusions (Fixed Mobile Convergence, referred to as FMC), And studied for 3GPP and Broadband Forum (Broadband Forum, referred to as BBF) interconnection and interflow.Pass through for user The scene of fixed broadband access network (Fixed Broadband Access Network) access mobile core net is, it is necessary to data Whole transmission path (data can be transmitted by fixed network and mobile network) on service quality (Quality of Service, letter Referred to as QoS) ensured.But the QoS of the fixed network circuit of H (e) NB accesses is typically owner and the fixed network by H (e) NB The signing limitation of operator.Therefore, when usual H (e) the NB accesses 3GPP core net access services of 3GPP UE, required QoS The QoS of the signing for the fixed network circuit that can be provided no more than fixed network operator.Otherwise, the QoS of UE access services cannot Ensure, particularly ensure bandwidth (Guaranteed Bitrate, referred to as GBR), it is easy to exceed.Therefore, for 3GPP nets For network, it is necessary to which control is accessed by the QoS aggregate demands of H (e) the NB all UE accessed Operational Visit no more than H (e) NB Fixed network circuit signing QoS ensure.In current techniques, pass through the broadband policy control cage in PCRF and fixed broadband access network Structure (Broadband Policy Control Framework, referred to as BPCF) is interacted, and realizes that QoS is ensured.BPCF is Policy control architecture in fixed broadband access network, to policy charging rule functional entity (Policy and Charging Rules Function, referred to as PCRF) resource request message, BPCF is according to the network strategy of fixed broadband access network, label About information etc. carries out resource and admission control or resource request message is transmitted to the network element (such as BNG) of other BBF access networks, then Resource and admission control (entrusting other network elements to perform resource and admission control) is performed by other network elements.
Fig. 3 is under route roaming scence in local in correlation technique, UE accesses H (e) NB attachment flow figure.In the flow In, H-PCRF initiates to set up S9 sessions and S9*Session, so as to implementation strategy intercommunication, ensures the QoS of UE Operational Visits.At this In flow, GPRS Tunnel Protocol (GPRS Tunneling Protocol, referred to as GTP agreements) is used between S-GW and P-GW.
Step S302：The upper electricity of HeNB, accesses fixed broadband access network.Fixed broadband access network be HeNB with distributing local IP Location.HeNB and SeGW sets up ipsec tunnel, detects there is network address translation between HeNB and SeGW in this process (Network Address Translation, NAT), if in the presence of if SeGW by the local ip address of the HeNB after NAT and Source user datagram protocol (User Datagram Protocol, referred to as UDP) port numbers are sent to HeNB.HeNB and HeMS Interaction, obtains configuration information, includes the IP address (i.e. HeNB GW or MME address) of S1 interfaces distal end.HeNB is registered to HeNB GW or MME.
Step S304：UE is sent to HeNB carried in Attach Request message, message user's mark, PDN marks；
Step S306：HeNB is sent to HeNB GW, MME carried in Attach Request message, message user's mark, PDN marks Knowledge, HeNB local ip address, alternatively, also carry source UDP port number (if detecting NAT)；
Step S308：MME sends to S-GW and creates conversation request message, carries user's mark, PDN marks, 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, and what carrying user mark, PDN marks, S-GW were located at visits Network identity, the HeNB local ip address of network are visited, alternatively, source UDP port number (if detecting NAT) is also carried；
Step S312：P-GW sends IP-CAN session establishments to home network PCRF (H-PCRF) and indicates message, and carrying is taken Band user's mark, PDN mark, visited network mark, HeNB local ip address, alternatively, also carry source UDP port number (if Detect NAT)；
Step S314：H-PCRF judges that UE is accessed by HeNB according to HeNB local ip address and source UDP port number, and And disappeared according to the network identity of visited network to visited network PCRF (V-PCRF) transmission PCRF initiation gateway control session foundation Breath carries HeNB local ip address and optional source UDP port number to set up in S9 sessions, message；
Step S316：V-PCRF determines fixed broadband access network according to HeNB local ip address, and sends PCRF to BPCF Gateway control session is initiated to set up message to set up S9*HeNB local ip address, source UDP port number are carried in session, message；
Step S318：BPCF returns to confirmation message to V-PCRF；
Step S320：V-PCRF returns to confirmation message to H-PCRF；
Step S322：H-PCRF returns to IP-CAN session establishments to P-GW and confirmed；
Step S324：P-GW is returned to S-GW and is created session response message, carries the IP address distributed for UE；
Step S326：S-GW is returned to MME and is created session response message；
Step S328：MME, HeNB GW, HeNB, UE, S-GW are further interacted, and set up and to change wireless access net loaded.
By above-mentioned flow, the session set up between H-PCRF, V-PCRF and BPCF is desirable when UE carries out Operational Visit When network distributes resource for it, H-PCRF is first by strategy and charging regulation (the Policy and Charging, abbreviation of formulation For PCC) rule QoS information BPCF is sent to by V-PCRF, so as to fixed broadband access network perform call access control.Then, The PCC rules that fixed broadband access network receives are sent to P-GW by H-PCRF.P-GW is according to PCC rules to corresponding data flow The head (being referred to as internal packet header) of IP bags carries out differentiated services code points (Differentiated Services Code Point, DSCP) mark, when business data flow IP bags reach SeGW when, SeGW will to IP bags progress IPSec encapsulation, and The head (being referred to as outside packet header) of IPSec IP bags is marked according to the DSCP of IP bags (internal packet header) during encapsulation.Together When, HeNB local ip address and optional source UDP port number can be sent to fixed broadband by V-PCRF and accessed by H-PCRF Net, fixed broadband access network is according to HeNB local ip address and optional source UDP port number to the number from 3GPP core nets According to being filtered.If corresponding IP bags can be matched, the business for proving the IP bags is by call access control, so that fixed wide Packet is carried out with access network further according to the DSCP of the IP packet headers forwarded.
But the premise of such scheme is home network supports to initiate with the intercommunication of fixed broadband access network, including H-PCRF S9 session establishments.If when H-PCRF does not support the intercommunication with fixed broadband access network, H-PCRF will not be set up with V-PCRF S9 sessions, can not also interact request call access control with BPCF.The PCC rules that can so cause H-PCRF to be issued to PCEF are The result of H-PCRF itself decision-makings.The PCC rules that PCEF is issued according to H-PCRF are carried out to the IP packet headers of business data flow DSCP is marked.When these business data flows reach SeGW, SeGW is not aware that these business datums are connect without fixed broadband Networking call access control, so according further to the DSCP in packet header outside the DSCP marked copies IPSec in internal packet header.If these are counted According to fixed broadband access network is reached, whether same fixed broadband access network will not also distinguish these business data flows by fixed wide With access network call access control.
Although HeNB local ip address and source in the prior art, can be provided to fixed broadband access network by PCRF Udp port is confirmed whether by call access control to allow fixed broadband to access net filtration IP bags.But it is due to that all accesses are same Individual HeNB UE IP bags are all packaged by same ipsec tunnel, therefore from the point of view of fixed broadband access network, it It cannot be distinguished by different UE IP bags.As long as wherein some UE is by fixed broadband access network call access control, then 3GPP cores Net will provide HeNB local ip address and alternatively source UDP port number, so other UE IP bags to fixed broadband access network It will be considered by fixed broadband access network by call access control.
So as to which other business for passing through call access control can be seized for those business data flows not through call access control UE The resource of data flow, causes whole fixed estropia (Fixed-Mobile Covergence, FMC) policy control machine at present The failure of system.
EPC scene, the problem of equally existing similar are accessed by HNB for UE.
For there is the business data flow through call access control UE to seize other business for passing through call access control in correlation technique The resource of data flow, the problem of causing the failure of whole FMC Policy Control mechanisms at present, not yet proposes effective solution party at present Case.

Fig. 5 is the attachment stream that UE of the present invention is accessed under 3GPP core nets, local route roaming scence by H (e) NB Cheng Tu.GTP agreements are used in Fig. 5 between S-GW and P-GW.Home network support and the policy control of fixed broadband access network are mutual It is logical.
Step S502：The upper electricity of HeNB, accesses fixed broadband access network.Fixed broadband access network be HeNB with distributing local IP Location.HeNB and SeGW sets up ipsec tunnel, detects there is network address translation between HeNB and SeGW in this process (Network Address Translation, NAT), if in the presence of if SeGW by the local ip address of the HeNB after NAT and Source user datagram protocol (User Datagram Protocol, referred to as UDP) port numbers are sent to HeNB.HeNB and HeMS Interaction, obtains configuration information, includes the IP address (i.e. HeNB GW or MME address) of S1 interfaces distal end.HeNB is registered to HeNB GW or MME.
Step S504：UE is sent to HeNB carried in Attach Request message, message user's mark, PDN marks；
Step S506：HeNB is sent to HeNB GW, MME carried in Attach Request message, message user's mark, PDN marks Knowledge, HeNB local ip address, alternatively, also carry source UDP port number (if detecting NAT)；
Step S508：MME sends to S-GW and creates conversation request message, carries user's mark, PDN marks, 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, and what carrying user mark, PDN marks, S-GW were located at visits Network identity, the HeNB local ip address of network are visited, alternatively, source UDP port number (if detecting NAT) is also carried；
Step S512：P-GW sends IP-CAN session establishments to H-PCRF and indicates message, carrying user is identified, PDN is identified, Visited network mark, HeNB local ip address, P-GW are the IP address that UE is distributed, and alternatively, also carry source UDP port number (such as Fruit detects NAT)；
Step S514：H-PCRF judges that UE is accessed by HeNB according to HeNB local ip address and source UDP port number, and And PCRF to V-PCRF sent according to the network identity of visited network initiate gateway control session and set up message to set up S9 sessions, HeNB local ip address and optional source UDP port number are carried in message；
Step S516：V-PCRF determines fixed broadband access network according to HeNB local ip address, and sends PCRF to BPCF Gateway control session is initiated to set up message to set up S9*HeNB local ip address, source UDP port number are carried in session, message；
Step S518：BPCF returns to confirmation message to V-PCRF；
Step S520：V-PCRF returns to confirmation message to H-PCRF；
Step S522：PCRF to be returned carry in IP-CAN session establishment confirmation messages, message to P-GW and supported with fixing wide Policy control intercommunication with access network is indicated.
Step S524：P-GW is returned to create carry in session response message, message to S-GW and is supported to access with fixed broadband The policy control intercommunication instruction of net, UE IP address.
Step S526：S-GW is returned to create to carry in session response message, message to MME and supported and fixed broadband access network Policy control intercommunication indicate, UE IP address.
Step S528：MME, HeNB GW, HeNB, UE, S-GW are further interacted, and set up and to change wireless access net loaded. In this process, MME also have support with the policy control intercommunication of fixed broadband access network instruction, UE IP address notify to HeNB GW (if present), HeNB.SeGW will be passed through by being wherein sent to HeNB message, and carry out IPSec encapsulation by SeGW.
By above-mentioned flow, the session set up between H-PCRF, V-PCRF and BPCF, the PDN connections for passing through foundation as UE When progress Operational Visit needs network for its distribution resource, the QoS information of the PCC rules of formulation is sent to by H-PCRF first BPCF, so that fixed broadband access network performs call access control.Then, the PCC rules that H-PCRF receives fixed broadband access network It is sent to PCEF.
For the downlink data of business data flow：P-GW (or strategy and charge execution function (Policy and Charging Enforcement Function, referred to as PCEF)) according to IP bag of the PCC rules to corresponding business data flow Head carry out DSCP mark after be sent to S-GW, when S-GW receive after IP bags will further to HeNB GW (if present) or HNB is forwarded, and now S-GW is indicated according to the support obtained in step S524 and the policy control intercommunication of fixed broadband access network The business data flow for judging the PDN connections be by fixed broadband access network call access control, therefore S-GW to H (e) NB GW or The IP bag identicals DSCP that the head for the IP bags that H (e) NB are sent carries out with receiving is marked.If S-GW is not obtained in step S524 It must support that the policy control intercommunication with fixed broadband access network is indicated, then S-GW will be sent out S-GW to H (e) NB GW or H (e) NB The heads of the IP bags sent carries out the different DSCP with IP packet headers that are receiving and marked, i.e., based on local policy to the IP bags of transmission Head re-starts DSCP marks, especially, marks the DSCP of lower priority.
According to the instruction supported with the control intercommunication of fixed broadband access network policy, S-GW can determine whether that the PDN that UE is set up connects Network support and the control intercommunication of fixed broadband access network policy that selected P-GW is located at are connect, i.e. S-GW judges mutual with it Logical network is to support to control intercommunication with fixed broadband access network policy, the business data flow of so this PDN connection be all through The resource and admission control of fixed broadband access network is crossed, just in the network of intercommunication is not with S-GW if not receiving the instruction Support to control intercommunication with fixed broadband access network policy, so the business data flow of this PDN connection is all without fixed broadband The resource and admission control of access network.
When these IP bags pass through SeGW, SeGW carried out during IPSec encapsulation according to prior art DSCP copy, enters one When walking IP bags arrival fixed broadband access network, fixed broadband access network makes a distinction according to IPSec IP packet header and treated, so that, IP bags without call access control business data flow will not seize other resources by the business data flow of call access control.
In addition S-GW can also judge whether the network belonging to the selected P-GW of PDN connections is supported by way of configuring With the policy control intercommunication of fixed broadband access network.Specifically, for example：
(1) networks of the S-GW according to belonging to P-GW address judges it, and then judge whether the network is supported and fixed width Policy control intercommunication with access network, so as to judge whether the business data flow of this PDN connection passes through fixed broadband access network Resource and admission control；
(2) networks of the S-GW according to belonging to the UE IP address that P-GW is distributed judges P-GW, and then judge whether the network props up The policy control intercommunication with fixed broadband access network is held, so as to judge the business data flow of this PDN connection whether by fixing (whether the business data flow i.e. from the P-GW or network passes through fixed broadband access network to the resource and admission control of broadband access network Resource and admission control).If there is HeNB GW in network, then above-mentioned functions can also be realized on HeNB GW.HeNBGW Indicate to judge the industry that the PDN is connected with the policy control intercommunication of fixed broadband access network according to the support obtained in step S528 Business data flow is that by fixed broadband access network call access control, therefore HeNB GW enter on the head of the IP bags sent to H (e) NB Row and the IP bag identicals DSCP marks received.Accessed if HeNB GW there is no support in step S528 with fixed broadband The policy control intercommunication of net indicates that then the head of the IP bags sent to H (e) NB GW to H (e) NB is different from by HeNB GW The DSCP marks of the IP packet headers received, i.e., re-start DSCP marks to the head of the IP bags of transmission based on local policy, special Not, the DSCP of lower priority is marked.When IP bags pass through SeGW, SeGW carried out during IPSec encapsulation according to prior art DSCP copy, when further IP bags reach fixed broadband access network, fixed broadband access network is carried out according to IPSec IP packet header Differentiation is treated, so as to will not seize other moneys by the business data flow of call access control without call access control business data flow Source.
In addition HeNB GW can also judge whether the network belonging to the selected P-GW of PDN connections props up by configuration mode Hold the policy control intercommunication with fixed broadband access network.As belonging to the UE IP address that HeNB GW are distributed according to P-GW judges P-GW Network, and then judge whether the network supports the policy control intercommunication with fixed broadband access network, so as to judge that this PDN connects The business data flow connect whether resource and admission control (the business number i.e. from the P-GW or network Jing Guo fixed broadband access network According to stream whether the resource and admission control Jing Guo fixed broadband access network).
Same similar function, can also be realized on SeGW.Implementation with above-mentioned HeNB GW is similar, SeGW Indicated to judge that the PDN connects according to the support in the message that step S528 is intercepted and captured and the policy control intercommunication of fixed broadband access network The business data flow connect is that by fixed broadband access network call access control, therefore SeGW is when carrying out IPSec encapsulation, the head of IP bags The DSCP marked copies in portion are to IPSec external IP packet header.If SeGW GW there is no branch in the message that step S528 is intercepted and captured Hold the policy control intercommunication with fixed broadband access network and indicate that then SeGW is by according to external IP packet header of the local policy to IPSec (i.e. the DSCP marks in the external IP packet header of IPSec are different from the DSCP in internal IP packet header) are marked, and are sent to HeNB. So, when packet reaches fixed broadband access network, fixed broadband access network makes a distinction according to IPSec IP packet header and treated. So as to which other resources by the business data flow of call access control will not be seized without call access control business data flow.
In addition the network that SeGW can also be judged belonging to the selected P-GW of PDN connections by configuration mode whether support with The policy control intercommunication of fixed broadband access network.If SeGW is according to being distributed the P-GW carried in the message intercepted and captured in step S528 UE IP address judges the network belonging to P-GW, and then judges whether the network supports the policy control with fixed broadband access network Intercommunication, so as to judge whether the resource and admission control Jing Guo fixed broadband access network (comes for the business data flow of this PDN connection From the business data flow of the P-GW or network whether the resource and admission control Jing Guo fixed broadband access network).
For upstream data：If HeNB is that upstream is carried out based on Reflective mechanism of the prior art Row data flow DSCP is marked.The IP reports of call access control are not carried out for those, because corresponding downstream data flow is via S- GW has carried out re-flagging for DSCP, therefore can correctly mark upstream according to existing Reflective.If HeNB is to be marked according to configuration QoS and DSCP mapping relations to carry out the DSCP of upstream, then HeNB is by basis Whether received in step S528 and support the policy control intercommunication with fixed broadband access network to indicate to perform DSCP marks：If not yet Receive, then HeNB will mark the DSCP in upstream IP packet header not according still further to QoS and DSCP mapping relations, but right IPSec external IP packet header carries out the DSCPs different from internal IP packet header and marked, i.e., according to IP bag of the local policy to IPSec Head re-starts DSCP marks, especially, is marked as the DSCP of lower priority, or enter according to Reflective mechanism Row DSCP is marked.If receiving, HeNB is according to QoS and DSCP mapping relations, the business data flow issued according to core net Corresponding up QoS marks the DSCP in upstream IP packet header.If HeNB is the mapping pass according to the QoS and DSCP of configuration Be carry out upstream DSCP mark, HeNB can also judge whether business data flow is carried out according to UE IP address Cross call access control.If no, HeNB will mark upstream IP not according still further to the QoS and DSCP of configuration mapping relations The DSCP in packet header, but the DSCPs marks different from internal IP packet header are carried out to IPSec external IP packet header, i.e., according to local Strategy re-starts DSCP marks to IPSec IP packet header, especially, is marked as the DSCP of lower priority, or press DSCP marks are carried out according to Reflective mechanism.If so, then HeNB according to the QoS and DSCP of configuration mapping relations, according to core The corresponding up QoS of the business data flow of heart hair off the net marks the DSCP in upstream IP packet header.If HeNB be according to The QoS and DSCP of configuration mapping relations come carry out upstream DSCP mark, HeNB can also be according to following methods Judge whether business data flow carried out call access control.When HeNB receives downlink data first, according to the QoS and DSCP of configuration Mapping relations to judge that the DSCP in the downstream IP packet header of the business data flow marks whether corresponding with the business data flow descending The DSCP that QoS is be mapped to is consistent：If consistent, the network element before showing (such as S-GW, HeNB GW or SeGW in the present invention) Re-flagging to the DSCP of downstream IP bag was not carried out, i.e., the business data flow carried out call access control.Now, HeNB is according to the QoS and DSCP of configuration mapping relations, and the up QoS issued according to core net carries out the DSCP of up IP bags Mark.If inconsistent, the network element (such as S-GW, HeNB GW or SeGW in the present invention) before showing carried out downstream IP The DSCP's of bag re-flags, i.e., the business data flow did not carry out call access control.Now, HNB is not according still further to configuration QoS and DSCP mapping relations, the up QoS issued according to core net come carry out upstream DSCP mark.But The DSCPs marks different from internal IP packet header are carried out to IPSec external IP packet header, i.e., according to IP of the local policy to IPSec Packet header re-starts DSCP marks, especially, is marked as the DSCP of lower priority, or according to Reflective mechanism Carry out DSCP marks.
H (e) NB are except HeNB is included, also including HNB.EPC scene is accessed by HNB for UE, is achieved in that similar , only it is briefly described below.
For downlink data, its process step is as follows：
(1) strategy whether S-GW, SGSN, HNB GW or SeGW are supported with fixed broadband access network according to being carried in message Control intercommunication indicate to judge the PDN connections business data flow whether the call access control Jing Guo fixed broadband access network, and under The IP packet header of row data flow carries out corresponding DSCP marks, and (if supporting, the IP bags of transmission are using the IP bag identicals with receiving DSCP is marked；If not supporting, the IP bags sent are marked using the DSCP different from the IP bags received, i.e., according to local policy pair The IP bags of transmission re-start DSCP marks)；
(2) S-GW, SGSN, HNB GW or SeGW according to configuration (S-GW according to UE IP address or P-GW address, SGSN, HNB GW and SeGW is according to UE IP address) judge whether the network belonging to the selected P-GW of PDN connections is supported and fixed broadband The policy control intercommunication of access network, so as to judge whether the business data flow of the PDN connections passes through connecing for fixed broadband access network Receive control, and carry out to IP packet header of downstream data flow corresponding DSCP marks (if supporting, the IP bags use of transmission is with receiving IP bag identicals DSCP is marked；If not supporting, the IP bags sent are marked using the DSCP different from the IP bags received, i.e. basis Local policy re-starts DSCP marks to the IP bags of transmission).
For upstream, HNB can use with the identical realization mechanisms of HeNB, repeat no more here.
Embodiment two
Fig. 6 is the PDN connections that UE of the present invention is accessed under 3GPP core nets, local route roaming scence by H (e) NB Ask flow chart.GTP agreements are used in Fig. 6 between S-GW and P-GW.Home network supports the strategy with fixed broadband access network Control intercommunication.
Step S602：UE sends PDN connection request messages to MME, and H (e) NB with adding the local IP of H (e) NB in the message Location and optional UPD port numbers.
Step S604：MME sends to S-GW and creates conversation request message, carries user's mark, PDN marks, 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, and what carrying user mark, PDN marks, S-GW were located at visits Network identity, the HeNB local ip address of network are visited, alternatively, source UDP port number (if detecting NAT) is also carried；
Step S608：P-GW sends IP-CAN session establishments to H-PCRF and indicates message, carrying user is identified, PDN is identified, Visited network mark, HeNB local ip address, P-GW are the IP address that UE is distributed, and alternatively, also carry source UDP port number (such as Fruit detects NAT)；
Step S610：H-PCRF judges that UE is accessed by HeNB according to HeNB local ip address and source UDP port number, and And PCRF to V-PCRF sent according to the network identity of visited network initiate gateway control session and set up message to set up S9 sessions, HeNB local ip address and optional source UDP port number are carried in message；
Step S612：V-PCRF determines fixed broadband access network according to HeNB local ip address, and sends PCRF to BPCF Gateway control session is initiated to set up message to set up S9*HeNB local ip address, source UDP port number are carried in session, message；
Step S614：BPCF returns to confirmation message to V-PCRF；
Step S616：V-PCRF returns to confirmation message to H-PCRF；
Step S618：H-PCRF returns to IP-CAN session establishments to P-GW and confirmed；
Step S620：P-GW is returned to S-GW and is created session response message, carries the plan supported with fixed broadband access network Slightly control intercommunication is indicated, is the IP address of UE distribution；
Step S622：S-GW is returned to MME and is created session response message, carries the strategy supported with fixed broadband access network Control intercommunication to indicate, be the IP address of UE distribution；
Step S624：MME, HeNB GW, HeNB, UE, S-GW are further interacted, and it is net loaded to set up and change wireless access, Carried in above-mentioned message and support that the policy control intercommunication with fixed broadband access network is indicated, be the IP address of UE distribution.Wherein send out Message toward HeNB will pass through SeGW, and carry out IPSec encapsulation by SeGW.
By above-mentioned flow, the session set up between PCRF and BPCF, when UE passes through newly-established PDN connections carry out business When access needs network for its distribution resource, the QoS information of the PCC rules of formulation is sent to BPCF by H-PCRF first, so as to Fixed broadband access network performs call access control.Then, the PCC rules that fixed broadband access network receives are sent to by H-PCRF PCEF。
For the downlink data of business data flow：P-GW (or PCEF) is according to PCC rules to corresponding business data flow The heads of IP bags is sent to S-GW after carrying out DSCP mark, when S-GW is received will be further to HeNB GW (if depositing after IP bags ) or HNB forwardings, S-GW is according to the support obtained in step S620 and the policy control intercommunication instruction of fixed broadband access network The IP bags for judging the business data flow of the PDN connections are that by fixed broadband access network call access control, therefore S-GW is to H (e) The IP bag identicals DSCP that the head for the IP bags that NB GW or H (e) NB are sent carries out with receiving is marked.If S-GW is in step S620 In there is no and support to indicate with the policy control intercommunication of fixed broadband access network, then S-GW will be to S-GW to H (e) NB GW or H (e) head for the IP bags that NB is sent carries out the DSCP marks of the IP packet headers different from receiving, i.e., according to this strategy to sending IP bags head re-start DSCP mark, especially, mark lower priority DSCP.
During implementation, according to the instruction supported with the control intercommunication of fixed broadband access network policy, S-GW can determine whether what UE was set up Network support that the selected P-GW of the PDN connections is located at and fixed broadband access network policy control intercommunication, i.e. S-GW judge with It is just being the business datum for supporting to control intercommunication, so this PDN connection with fixed broadband access network policy in the network of intercommunication Stream is all the resource and admission control by fixed broadband access network, if not receiving the instruction, with S-GW just in intercommunication Network be do not support with fixed broadband access network policy control intercommunication, so the business data flow of this PDN connection all without The resource and admission control of fixed broadband access network.When IP bags pass through SeGW, SeGW enter during IPSec encapsulation according to prior art Row DSCP copy, when further IP bags reach fixed broadband access network, fixed broadband access network is entered according to IPSec IP packet header Row differentiation is treated, so that, it will not seize other business data flows for passing through call access control without call access control business data flow Resource.
In addition S-GW can also judge whether the network belonging to the selected P-GW of PDN connections is supported by way of configuring With the policy control intercommunication of fixed broadband access network.For example：
(1) networks of the S-GW according to belonging to P-GW address judges it, and then judge whether the network is supported and fixed width Policy control intercommunication with access network, so as to judge whether the business data flow of this PDN connection passes through fixed broadband access network Resource and admission control；
(2) networks of the S-GW according to belonging to the UE IP address that P-GW is distributed judges P-GW, and then judge whether the network props up The policy control intercommunication with fixed broadband access network is held, so as to judge the business data flow of this PDN connection whether by fixing (whether the business data flow i.e. from the P-GW or network passes through fixed broadband access network to the resource and admission control of broadband access network Resource and admission control).
If there is HeNB GW in network, then above-mentioned functions can also be realized on HeNB GW.HeNB GW are according in step The support obtained in rapid S624 indicates to judge the business data flow that the PDN is connected with the policy control intercommunication of fixed broadband access network It is that by fixed broadband access network call access control, therefore HeNB GW are carried out and received on the head of the IP bags sent to H (e) NB IP bag identicals DSCP mark.If HeNB GW there is no the strategy supported with fixed broadband access network in step S624 Intercommunication is controlled to indicate, then HeNB GW carry out the head of the IP bags sent to the IP for being different from receiving from H (e) NB GW to H (e) NB The DSCP marks of packet header, i.e., re-start DSCP marks, especially, mark to the head of the IP bags of transmission according to this strategy The DSCP of lower priority.When IP bags pass through SeGW, and SeGW carries out IPSec encapsulation copying for DSCP is carried out according to prior art Shellfish, when further IP bags reach fixed broadband access network, fixed broadband access network makes a distinction pair according to IPSec IP packet header Treat, so that other resources by the business data flow of call access control will not be seized without call access control business data flow.
In addition HeNB GW can also judge whether the network belonging to the selected P-GW of PDN connections props up by configuration mode Hold the policy control intercommunication with fixed broadband access network.As belonging to the UE IP address that HeNB GW are distributed according to P-GW judges P-GW Network, and then judge whether the network supports the policy control intercommunication with fixed broadband access network, so as to judge that this PDN connects The business data flow connect whether resource and admission control (the business number i.e. from the P-GW or network Jing Guo fixed broadband access network According to stream whether the resource and admission control Jing Guo fixed broadband access network).
Same similar function, can also be realized on SeGW.SeGW is according to the branch in the message that step S624 is intercepted and captured The policy control intercommunication with fixed broadband access network is held to indicate to judge that the business data flow that the PDN is connected is connect by fixed broadband Networking call access control, therefore SeGW is when carrying out IPSec encapsulation, the DSCP marked copies on the head of IP bags to IPSec outside IP packet header.If SeGW there is no the policy control intercommunication supported with fixed broadband access network in the message that step S624 is intercepted and captured Indicate, then SeGW IPSec external IP packet header will be marked according to local policy, and be sent to HeNB.So, data are worked as When bag reaches fixed broadband access network, fixed broadband access network makes a distinction according to IPSec IP packet header and treated.So as to without connecing Control business data flow of receiving will not seize other resources by the business data flow of call access control.
In addition the network that SeGW can also be judged belonging to the selected P-GW of PDN connections by configuration mode whether support with The policy control intercommunication of fixed broadband access network.If SeGW is according to being distributed the P-GW carried in the message intercepted and captured in step S624 UEIP addresses judge the network belonging to P-GW, and then it is mutual with the policy control of fixed broadband access network to judge whether the network is supported It is logical, so as to judge whether the resource and admission control Jing Guo fixed broadband access network (comes from for the business data flow of this PDN connection The business data flow of the P-GW or network whether the resource and admission control Jing Guo fixed broadband access network).
For upstream data：If HeNB is that upstream is carried out based on Reflective mechanism of the prior art Row data flow DSCP is marked.The IP reports of call access control are not carried out for those, because corresponding downstream data flow is via S- GW has carried out re-flagging for DSCP, therefore can correctly mark upstream according to existing Reflective.If HeNB is that the DSCP that upstream is carried out according to the QoS and DSCP of configuration mapping relations is marked, then HeNB is by root According to whether being received in step S624 and support to indicate with the policy control intercommunication of fixed broadband access network to perform DSCP marks：If Do not receive, then HeNB will mark the DSCP in upstream IP packet header not according still further to QoS and DSCP mapping relations, but The DSCPs marks different from internal IP packet header are carried out to IPSec external IP packet header, i.e., according to IP of the local policy to IPSec Packet header re-starts DSCP marks, especially, is marked as the DSCP of lower priority, or according to Reflective mechanism Carry out DSCP marks.If receiving, HeNB is according to QoS and DSCP mapping relations, the business datum issued according to core net Corresponding up QoS is flowed to mark the DSCP in upstream IP packet header.If HeNB is closed according to configuration QoS and DSCP mapping Be carry out upstream DSCP mark, HeNB can also judge whether business data flow is carried out according to UE IP address Cross call access control.If no, HeNB will mark upstream IP packet header not according still further to QoS and DSCP mapping relations DSCP, but the DSCPs marks different from internal IP packet header are carried out to IPSec external IP packet header, i.e., according to local policy pair IPSec IP packet header re-starts DSCP marks, especially, is marked as the DSCP of lower priority, or according to Reflective mechanism carries out DSCP marks.If so, then HeNB is issued according to QoS and DSCP mapping relations according to core net The business data flow corresponding up QoS mark the DSCP in upstream IP packet header.If HeNB is the QoS according to configuration The DSCP marks of upstream are carried out with DSCP mapping relations, HeNB can also judge business number according to following methods Whether call access control was carried out according to stream.When HeNB receives downlink data first, according to the QoS of configuration and DSCP mapping relations Judge that the DSCP in the downstream IP packet header of the business data flow marks whether that descending QoS corresponding with the business data flow is be mapped to DSCP it is consistent：If consistent, the network element (such as S-GW, HeNB GW or SeGW in the present invention) before showing was not carried out To re-flagging for the DSCP of downstream IP bag, i.e., the business data flow carried out call access control.Now, HeNB is according to configuration QoS and DSCP mapping relations, the up QoS issued according to core net come carry out up IP bags DSCP mark.If no Unanimously, then the network element (such as S-GW, HeNB GW or SeGW in the present invention) before showing carried out the DSCP of downstream IP bag weight New mark, i.e., the business data flow did not carry out call access control.Now, HNB does not reflect according still further to the QoS and DSCP of configuration Penetrate relation, the up QoS issued according to core net come carry out upstream DSCP mark.But to IPSec outside IP packet header carries out the DSCPs different from internal IP packet header and marked, i.e., IPSec IP packet header is re-started according to local policy DSCP is marked, especially, is marked as the DSCP of lower priority, or carry out DSCP marks according to Reflective mechanism Note.
EPC scene is accessed by HNB for UE, is achieved in that similar, is only briefly described below.
For downlink data, (1) S-GW, SGSN, HNB GW or SeGW is wide with fixing according to support whether is carried in message Policy control intercommunication with access network indicates whether the business data flow for judging the PDN connections passes through connecing for fixed broadband access network Receive control, and carry out to IP packet header of downstream data flow corresponding DSCP marks (if supporting, the IP bags use of transmission is with receiving IP bag identicals DSCP is marked；If not supporting, DSCP marks are carried out to the IP bags of transmission according to local policy)；(2)S-GW、 SGSN, HNB GW or SeGW according to configuration (S-GW according to UE IP address or P-GW address, SGSN, HNB GW and SeGW according to UE IP address) whether the network that judges belonging to the selected P-GW of PDN connections support policy control with fixed broadband access network Intercommunication, thus judge the PDN connections business data flow whether the call access control Jing Guo fixed broadband access network, and to lower line number Carrying out corresponding DSCP marks according to the IP packet header of stream, (if supporting, the IP bags of transmission are marked using the IP bag identicals DSCP with receiving Note；If not supporting, DSCP marks are carried out to the IP bags of transmission according to local policy)
For upstream, HNB can use with the identical realization mechanisms of HeNB, do not repeating here.
