Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of transmission method and system of gateway address information.
Background technology
Third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) grouping system (the Evolved Packet System of evolution, referred to as EPS) by Universal Terrestrial Radio Access Network (the Evolved Universal Terrestrial Radio Access Network of evolution, referred to as E-UTRAN), mobile management unit (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, HSS), authentication and authorization charging (the Authentication of 3GPP, Authorization and Accounting, referred to as AAA) server, "Policy and Charging Rules Function (Policy and Charging Rules Function, referred to as PCRF) entity and other support nodes composition.
As shown in fig. 1, wherein MME is responsible for the related work of the chains of command such as the processing of mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment be connected with E-UTRAN, forwarding data between E-UTRAN and P-GW, and be responsible for the pending datas such as paging are carried out to buffer memory; P-GW is the borde gateway of EPS and packet data network (Packet Data Network, referred to as PDN) network, is responsible for the access of PDN and the function such as forwarding data between EPS and PDN; Wherein S-GW and P-GW, as the data gateway of EPC network, refer to S-GW and/or P-GW with the EPC gateway in the present invention, and when network design is realized, both can close and establish also and can set up separately.PCRF is the "Policy and Charging Rules Function entity, it is by receiving interface Rx and carrier network agreement (Internet Protocol, referred to as IP) business network is connected, obtain business information, in addition, PCRF is connected with the gateway device in network by the Gx/Gxc interface, be responsible for initiating the foundation of IP carrying, guarantee the service quality (Quality of Service, referred to as QoS) of business datum, and carry out charging control.
Current EPS system is supported the intercommunication with non-3 GPP system.EPS and non-3 GPP system are by the intercommunication of S2a/b/c Interface realization, and P-GW is as the anchor point between 3GPP and non-3 GPP system.In the system architecture diagram of EPS, the non-3 GPP system access is divided into trustless non-3GPP access and the non-3GPP access of trusted; Wherein, trustless non-3GPP access needs to be connected with P-GW through the packet data gateway (Evolved Packet Data Gateway, referred to as ePDG) of evolution, and the interface between ePDG and P-GW is S2b; The non-3GPP access of trusted can directly be connected with P-GW by the S2a interface, and the S2a interface adopts the PMIP/GTP agreement to carry out information interaction; In addition, the S2c interface provides subscriber equipment (User Equipment, referred to as UE, also referred to as terminal) control and the mobility support relevant to user's face between P-GW, the mobility management protocol of its support is for supporting mobile IP v 6 (the Mobile IPv6 Support for Dual Stack Hosts and Routers of two stacks, referred to as DSMIPv6), it can be used for trustless non-3GPP and the non-3GPP access of trusted.
WLAN (wireless local area network) (Wireless LAN, referred to as WLAN) can be used as trustless non-3GPP access EPS, and can adopt S2b during access, and the S2c of trust and fly-by-night S2c access, be illustrated in figure 1 S2b and S2c scene.The groundwork mechanism of several scenes is as follows:
1) S2b access.Set up the IPsec tunnel between UE and ePDG, ePDG and P-GW set up GTP or PMIPv6 tunnel, two ends tunnel cascade, the business that the IP operation that the IP address visited network operator that UE is terminal distribution by P-GW provides or third party service provider provide.The business datum of UE is after ePDG arrives fixed network, user data is again through the ipsec tunnel between UE and ePDG, to encapsulate, the packet that is to say the terminal UE that the BNG of fixed network can perceive is the outer layer address in IPsec tunnel, specifically, downlink data packet for example, its source address is the address of ePDG, and destination address is the local ip address (this IP address is that UE distributes by fixed network) of UE.
The S2c access of 2) trusting.Under this access way, ePDG does not participate in, UE directly and P-GW set up IPsec tunnel and DSMIP tunnel, the business that the IP operation that the IP address visited network operator that terminal UE is terminal distribution by P-GW provides or third party service provider provide.The business datum of UE is after leaving P-GW arrival fixed network, user data is again through the ipsec tunnel between UE and P-GW, to encapsulate, the packet that is to say the terminal UE that the BNG of fixed network can perceive is the outer layer address in IPsec tunnel, specifically, downlink data packet for example, its source address is the address of P-GW, and destination address is the local ip address (this IP address is that UE distributes by fixed network) of UE.
3) fly-by-night S2c access, under this access way, the access of ePDG participation terminal UE.UE and ePDG set up the IPsec tunnel, the city of this ipsec tunnel under, UE sets up ipsec tunnel and DSMIP tunnel with P-GW again, the business that the IP operation that the IP address visited network operator that terminal UE is terminal distribution by P-GW provides or third party service provider provide.The packing forms of packet in fixed network is with the situation of S2b access.
The stream of the business datum of above three kinds of patterns is called the EPC-routed business data flow, shown in the heavy line in Fig. 1.
Except above access way, terminal UE can also directly be utilized the local address visit external business of being distributed by fixed network, this part data flow is called NSWO (non-seamless WLAN offload, non-seamless WLAN shunting) data flow, shown in the dotted line in Fig. 1.The packet of these business datums, be to encapsulate with the local address of terminal and the address of Correspondent Node, that is to say the local address information that the perceived outer layer address of fixed network is UE.
In current agreement, set up gateway control session (gateway control session) on the S9a interface between PCRF and BPCF for tactful intercommunication, and in the process of the gateway control session on setting up the S9a interface, P-GW/ePDG offers PCRF by the P-GW/eDPG address information, and offer BPCF by PCRF, pass to again successively BNG.This P-GW/eDPG address information is business datum for distinguishing EPC-routed and the business datum of NSWO in the fixed network side, thus independent business datum (the especially business datum of the EPC-routed) QoS (especially bandwidth) that guarantees.Wherein, in the network (next step evolvement network) merged, BPCF may not exist, but by PCRF directly and BNG set up interface (such as the Gxd interface) and transmit above-mentioned P-GW/ePDG address information.
Terminal UE may have a plurality of PDN to connect simultaneously, corresponding a plurality of P-GW and P-GW address, and the P-GW address be all by by a plurality of PDN Connection Sharings the S9a interface on gateway control session send to fixed network side (BPCF/BNG), often set up PDN and connect, corresponding P-GW address will send to fixed network side (BPCF/BNG).Its operation is referring to flow chart 2, and concrete steps are described below:
Step S201: terminal UE accesses EPC by WLAN, and sets up first PDN connection, is called PDN in the present invention and connects 1.
Step S202:P-GW is that the operation of IP-CAN (IP-Connectivity Access Network, IP connects Access Network) session establishment is initiated in PDN connection 1 on the Gx interface.According to existing protocol, the address of P-GW-1 can bring PCRF.
The gateway control session that step S203:PCRF initiates on the S9a interface is set up operation.According to existing protocol, the address of P-GW-1 can send to BPCF.
BPCF is the fixed network network element, and BPCF further sends to fixed network BNG to the P-GW-1 address information, can adopt directly (by the R interface) or mode (by fixed network AAA) etc. indirectly.
Step S204: the BNG in fixed network utilizes the P-GW-1 address information to distinguish the business datum of EPC-routed and the business datum of NSWO, thus independent business datum (the especially business datum of the EPC-routed) QoS (especially bandwidth) that guarantees.
Step S205: second PDN of terminal UE connects foundation, and this PDN connects and is called PDN connection 2.
Step S206:P-GW is that PDN connects 2 initiation IP-CAN session establishment operations on the Gx interface.According to existing protocol, the address of P-GW-2 can bring PCRF.
Step S207:PCRF initiates the gateway control session retouching operation on the S9a interface, and gateway control and QoS rule provide operation.According to existing protocol, the address of P-GW-2 can send to BPCF.
BPCF is the fixed network network element, and BPCF further sends to fixed network BNG to the P-GW-2 address information, can adopt directly (by the R interface) or mode (by fixed network AAA) etc. indirectly.
Step S208: the BNG in fixed network utilizes P-GW-1 and P-GW-2 address information to distinguish the business datum of EPC-routed and the business datum of NSWO, thus independent business datum (the especially business datum of the EPC-routed) QoS (especially bandwidth) that guarantees.
Step S209: if also have more PDN to connect, set up, corresponding P-GW address information can be delivered to the BNG of fixed network by the way, and BNG utilizes the address information coupling/filtering data bag of these P-GW.
Step S210: last PDN connection of terminal is released.This scene occurs in, in the time of the direct attachment removal of UE, or UE successively each PDN connect until last PDN connects is released.
Step S211:PCRF initiates the gateway control session terminating operation on the S9a interface.
Step S212: according to existing protocol, the BPCF of fixed network and BNG should deletion or deexcitation and the interface related contexts of this S9a, comprising all P-GW address informations.
In UNE (next step evolvement network), PCRF and BNG direct interface, be now to initiate gateway control session foundation/retouching operation on the interface between PCRF and BNG.Its information transmission mechanism is the same.
By analyzing above-mentioned flow process, can find, when terminal UE is only deleted one of them PDN connection, this corresponding P-GW address but can not be deleted from the fixed network side, and the address information of this P-GW is in fixed network side or effective.This has just caused fixed network to have redundant information, the more important thing is, BNG can be used as effective information for the matched data bag by this P-GW address information, serious reduction the matching efficiency of fixed network to data.

Embodiment mono-
In the present embodiment, in the gateway control session on the S9a interface, except the address information of transmitting P-GW, also to transmit an operation indicating bit.The effect of this operation indicating bit is that this P-GW address information of indication is to activate or deactivate, or installs or unloading, or effectively still invalid.
As shown in Figure 3, the present embodiment flow process specifically describes as follows:
Step S301-S302: referring to step S201-S202;
Step S303:PCRF is subject to the triggering of the IP-CAN session establishment of step S302, finds the not gateway control session corresponding with this IP-CAN session of current S9a interface, and the gateway control session that PCRF initiates on the S9a interface is set up operation.
Wherein, PCRF judges on the S9a interface that the criterion that whether exists for gateway control session corresponding to IP-CAN session is as follows: because the gateway control session on the S9a interface and IP-CAN session are many-to-one relations, if it is on this PCRF that PCRF finds this IP-CAN session, serve first IP-CAN session (the IP-CAN session that first PDN connects) of this UE, think that this IP-CAN session does not have the gateway control session on corresponding S9a interface.
The address of P-GW-1 and corresponding operation indicating bit 1 send to BPCF.BPCF is the fixed network network element, and BPCF further sends to fixed network BNG to the address of P-GW-1 and corresponding operation indicating bit 1, can adopt directly (by the R interface) or mode (by fixed network AAA) etc. indirectly.
Due to current be that PDN connect to set up operation, therefore, indicating bit should be set to: activate/install/effectively/enable.
Step S304: the BNG in fixed network is according to the indication of operation indicating bit, utilize the P-GW-1 address information to distinguish the business datum of EPC-routed and the business datum of NSWO, thus independent business datum (the especially business datum of the EPC-routed) QoS (especially bandwidth) that guarantees.
Step S305-S306: referring to step S205-S206;
Step S307:PCRF is subject to the triggering of the IP-CAN session establishment of step S306, find that there be the gateway control session corresponding with this IP-CAN session in current S9a interface, PCRF initiates the gateway control session retouching operation on the S9a interface, and gateway control and QoS rule provide operation.
Wherein, PCRF judges on the S9a interface that the criterion that whether exists for gateway control session corresponding to IP-CAN session is as follows: the gateway control session on the S9a interface and IP-CAN session are many-to-one relations, if it is on this PCRF that PCRF finds this IP-CAN session, serve second, third of this UE .... (non-first) IP-CAN session, think that there has been the gateway control session on corresponding S9a interface in this IP-CAN session.
The address of P-GW-2 and corresponding operation indicating bit 2 send to BPCF.BPCF is the fixed network network element, and BPCF further sends to fixed network BNG to the address of P-GW-2 and corresponding operation indicating bit 2, can adopt directly (by the R interface) or mode (by fixed network AAA) etc. indirectly.
Due to current be that PDN connect to set up operation, therefore, indicating bit should be set to: activate/install/effectively/enable.
Step S308: the BNG in fixed network is according to the indication of operation indicating bit, utilize P-GW-1 and P-GW-2 address information to distinguish the business datum of EPC-routed and the business datum of NSWO, thus independent business datum (the especially business datum of the EPC-routed) QoS (especially bandwidth) that guarantees.
Step S309: if also have more PDN to connect, set up, corresponding P-GW address information can be delivered to the BNG of fixed network by the way, and BNG utilizes the address information coupling/filtering data bag of these P-GW.
Step S310: one of them PDN connection of terminal is released.In the present embodiment, hypothesis PDN connection 1 is released.
Step S311:P-GW-1 initiates IP-CAN session-1 terminating operation.
Step S312:PCRF is subject to the triggering of the IP-CAN session termination of step S311, find also to exist other IP-CAN sessions corresponding with the gateway control session on current S9a interface (corresponding other PDN connection), PCRF initiates the gateway control session retouching operation on the S9a interface, and gateway control and QoS rule provide operation.The address of P-GW-1 and corresponding operation indicating bit 1 send to BPCF.BPCF is the fixed network network element, and BPCF further sends to fixed network BNG to the address of P-GW-1 and corresponding operation indicating bit 1, can adopt directly (by the R interface) or mode (by fixed network AAA) etc. indirectly.
Perhaps, as further optimization, can only send operation indicating bit 1 corresponding to P-GW-1 address to BPCF.BPCF further sends to fixed network BNG to operation indicating bit 1.
Due to current be PDN Connection Release operation, so indicating bit should be set to: deexcitation/unloading/invalid/forbid.
Step S313:BNG deletes or this P-GW-1 address information of deexcitation, no longer filtration and the QoS resource guarantee for packet by this information.
Step S314: other PDN Connection Releases of this UE, if corresponding PCRF also serve this UE other do not have the PDN discharged to connect, operating procedure is referring to S311-S313; If all IP-CAN sessions of certain UE of this PCRF service all are released, perform step S211-S212.
Because each PDN establishment of connection can be set up the IP-CAN session on corresponding Gx interface, and all can report the address information of P-GW in IP-CAN session establishment process, even that two PDN connection selections is same P-GW, situation is also like this.Therefore, in above-mentioned process step, after PCRF receives IP-CAN session establishment or terminating operation, also to do one deck judgement, and following two kinds of possible operations are arranged:
Scheme one:
1) if PCRF receives a new P-GW address, PCRF reports fixed network;
2) if the P-GW address information that PCRF receives with reported and submitted last time the P-GW information to fixed network identical, PCRF does not need again to report fixed network;
3) if PCRF receives IP-CAN session deletion action, but also there are other corresponding IP-CAN session, PCRF undos in corresponding P-GW address information;
4) if PCRF receives IP-CAN session deletion action, and no longer there are other corresponding IP-CAN sessions in corresponding P-GW address information, and PCRF notice fixed network is deleted this P-GW address information;
Scheme two:
When PCRF receives IP-CAN session establishment or terminating operation at every turn, all to fixed network, initiate indication installation or the deletion action of P-GW address information.
In UNE (next step evolvement network), PCRF and BNG direct interface, be now to initiate gateway control session foundation/retouching operation on the interface between PCRF and BNG.Information transmission mechanism is the same.
In addition, as a kind of distortion to the present embodiment, operation indicating bit 1 corresponding to P-GW-1 address also can omit, but be the operation that special value is indicated BPCF by the P-GW address information is set, for example, by the P-GW address information is set, being that effective value (nonzero value) indicates fixed network (BPCF and BNG) to install and use, is that full null value indicates fixed network to cancel this address information by the address information that P-GW is set.
Embodiment bis-
In the present embodiment, in gateway control session on the S9a interface, transmit in the following way the address information of P-GW: PCRF and construct new QoS rule by the P-GW address information, because the QoS rule is by foundation or modification or deletion action, therefore by the operation of QoS rule, just can indicate the P-GW address information whether effective in the fixed network side, if invalid, just deleted.
PCRF initiates the determination methods of gateway control session foundation/modification/deletion action with embodiment mono-.
As shown in Figure 4, the present embodiment flow process specifically describes as follows:
Step S401-S402: referring to step S201-S202;
The QoS rule that step S403:PCRF structure comprises the P-GW-1 address information.Concrete QoS rule comprises SDF template (service data flow template, the business datum flow template), and five-tuple information is arranged in SDF template, wherein the P-GW-1 address information is as one in five-tuple information, wherein involved.
The gateway control session that step S404:PCRF initiates on the S9a interface is set up operation.And QoS rule is sent to BPCF.The address information that has wherein comprised P-GW-1.
BPCF is the fixed network network element, and BPCF further sends to fixed network BNG to QoS rule information, can adopt directly (by the R interface) or mode (by fixed network AAA) etc. indirectly.
