Description
Technical field
The present invention relates to communication field, relate in particular to a kind of bearing mapping method and equipment.
Background technology
The framework of EPS (Evolved Packet System) system, as shown in Figure 1, UE (UserEquipment wherein, user terminal) and E-UTRAN (Evolved-Terrestrial Radio Access Network, evolved terrestrial access network) (the Uu interface between comprising) belongs to the category of Access Network, all the other nodes belong to the category of core net, have defined corresponding interface between the different nodes.The transmission direction of downlink service data is " Operator ' s IP Service "-PDN (Packet Data Network, packet data network) Gateway-〉Serving Gateway-〉E-UTRAN-〉UE; The transmission of uplink data direction is opposite with downlink data.QoS (Quality of Service, service quality) mechanism is the critical function of EPS system, provides certain transmission availability and reliability guarantee at different business, makes the user keep favorable experience in communication process.
QoS among EPS control is based on that carrying carries out.The qos parameter of EPS carrying level comprises: ARP (Allocation and Retention Priority, distribute and preserve priority), QCI (QoS ClassIdentifier, the QoS class letter), GBR (Guaranteed Bit Rate, guarantee bit rate) and MBR (Maximum Bit Rate, maximum bit rate).Wherein, ARP is used for definition when resource-constrained, and whether the foundation of a carrying, renewal are received or refuse.ARP also is applied to the Access Network side, and whether definition allows certain carrying of having set up is discharged when resource-constrained (as switching) generation unexpectedly.QCI is the relevant qos parameter of access network node, is used for the transmission policy of control data bag, as the configuration of scheduling, admittance, queue management and link layer protocol.GBR is designated as the transmission rate that a GBR carrying provides.The upper limit of the transmission rate that MBR provides for GBR carrying, in present protocol version, MBR should equal GBR.
UE and P-GW (PDN Gateway, grouped data network gateway) mutual all business data packet all need to be mapped in the UE EPS carrying with corresponding qos parameter and transmit, each network element node between UE and the P-GW is according to the indication of the UE EPS bearing identification that carries in the business data packet, packet is dispatched and transmitted according to the corresponding qos parameter of UEEPS carrying.So-called packet is mapped to UE EPS carrying and is meant packet is encapsulated, and increases the sign of a GTP-TEID (GTP TunnelEndpoint Identifier, tunnel endpoint identifier territory) as the EPS carrying in outer packet header.Packet all network element nodes of process, the network element node carries out data dispatch and forwarding according to the GTP-TEID in outer packet header.The packet that all GTP-TEID are identical will be employed identical data dispatch and forwarding strategy.
In the EPS standard, defined 2 kinds of options simultaneously, the IP bag that is used for that core net is received is mapped to corresponding UE EPS carrying.The two difference is on the S5/S8 interface: option one has adopted GTP based S5/S8 (seeing 23.401), and option 2 has adopted PMIP based S5/S8 (seeing 23.402).In option one, PGW both had been responsible for distinguishing UE (i.e. the IP bag of identification arrival is to issue which UE's), also was responsible for distinguishing each EPS carrying under the UE (determining promptly the IP bag of issuing certain UE should be placed in which EPS carrying of this UE); And in option 2, PGW only is responsible for distinguishing UE (i.e. the IP bag that identification arrives is to issue which UE's), SGW then on the working foundation of PGW, is responsible for distinguishing each EPS carrying under the UE (determining promptly the IP bag of issuing certain UE should be placed in which EPS carrying of this UE).
Specifically do not distinguish the PGW of RN and the SGW of RN in the following description, but the two is referred to as RN P/S-GW.If that system uses is option one (GTP based S5/S8), that so described RN-GW refers to is exactly RN P-GW; And if system uses is option 2 (PMIP based S5/S8), that so described RN-GW refers to is exactly RN-SGW.
Mobile communication system in future, as B3G (Beyond three Generation, back three generations) or LTE-A (LTE Advance, evolved LTE) in, introduced RN (Relay Node, via node) in order to improve throughput of system and to increase network coverage, as shown in Figure 2, RN has dual identity in system: at first it is as a UE, and access network is set up oneself carrying: RN EPS carrying; Simultaneously, it is as eNB (Evolved Node B, evolved base station), and for the UE under it (UE by the RN service is R-UE) provides service, the UE EPS carrying that UE set up need be mapped in the EPS carrying of RN to be transmitted.That is to say: the carrying mapping is can be nested.The nested exactly packet that is mapped in the UE EPS carrying encapsulation once more of so-called carrying mapping, in outer packet header, add another GTP-TEID, thereby many internal layer tunnels (as: UE EPS carrying) pooled an outer layer tunnel (as: RN EPS carrying).
In having the system of RN, as shown in Figure 3, finish packet after the mapping of UE EPS carrying, RN P/S-GW node also needs to fill in according to the corresponding QCI attribute of UE EPS carrying the indication of outer IP bag middle wrapping head information, DSCP (DiffServ Code Point, Differentiated Services Code Point) territory for example.Then, RNP/S-GW mails to packet the service eNB of UE.
For descending, finish the mapping of R-UE EPS and RN EPS carrying at RN P/S-GW.A kind of mapping ruler is: RN P/S-GW determines the target RN that IP wraps according to the purpose IP address of IP bag, and according to the indication of IP bag middle wrapping head information, for example the DSCP territory determines which bar RN EPS carrying this packet should be mapped in.For up,, shine upon based on the QCI information of R-UEEPS carrying and finish in the mapping that RN finishes R-UE EPS and RN EPS carrying.No matter up-downgoing, the R-UE EPS carrying with similar QoS attribute (determining according to QCI) can be mapped in same the RN EPS carrying.
Be in the prior art:
RN P/S-GW is carried to RN EPS when mapping carrying carrying out UE EPS, can only be according to the indication of the IP bag middle wrapping head information of receiving, and for example carry out in the DSCP territory.QCI fills in because the DSCP territory is based on, and it can only partly reflect the QoS attribute of UE EPS.
Other QoS attributes of UE EPS, as: ARP, GBR, MBR does not obtain considering when the carrying mapping.So, may cause the service quality of corresponding UE EPS to be not being met or satisfied excessively.
Simultaneously, also decide AMBR (Aggregate Maximum Bit Rate, the Aggregate Maximum Bit Rate) attribute of UE in the R8 agreement, be used to control all NGBR of UE (Non-GBR: non-assurance bit rate) Ye Wu maximum rate.In R8, descending UE AMBR can be used the speed of eating dishes without rice or wine of control UE by eNB.But in the scene of RN is arranged, because RN P/S-GW node can't obtain the waste of radio resources that the AMBR parameter value of UE will cause the Un mouth.

Embodiment
The embodiment of the invention proposes: the core net gateway node obtains the QoS information of carrying to the high-rise AP message parse through its transmission; Described core net gateway node is set up the described mapping relations that are carried between the described RN EPS carrying according to the QoS information of the QoS information of described carrying and storage in advance and the mapping relations between the RN EPS carrying.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Inventive concept is applicable to 2 kinds of options that define in the aforementioned EPS standard simultaneously, a kind of protocol stack architecture figure related to the present invention as shown in Figure 4 among the 3GPP, wherein the core net gateway node is RN P/S GW, and as can be seen from Figure 4 RN has dual identity in this framework:
(1) at first RN has the identity of UE, so it has the SGW/PGW (being called for short RN-GW) of oneself.For downlink data, the packet that external node is issued RN all will pass through RN-GW, sends to the current serving BS DeNB of RN (Donor eNB, donor base station), and DeNB issues RN on the Un mouth then; For upstream data, the packet that RN sends to external node all will send to RN-GW through the current serving BS DeNB of RN, and RN-GW sends it to external node then.
(2) secondly, for the UE that inserts RN, RN has the identity of eNB.For downlink data, need through RN-GW, DeNB send to the serving BS (being RN) of UE by the SGW/PGW of UE (being called for short UE-GW), RN issues UE on the Uu mouth then.For upstream data, need send to RN through the Uu mouth earlier by UE, pass through DeNB more successively, RN-GW sends to UE-GW, sends to external node by UE-GW at last.
Control plane as shown in Figure 5 in this framework, the S1-AP of control plane and SCTP (the Stream Control Transmission Protocol that is used to ensure the TNL transmission reliability, SCTP) agreement ends in the MME (Mobility Management Entity, Mobility Management Entity) (serving MME of R-UE) of RN and UE.S1-AP (S1 Application Protocol, S1 Application Protocol) message is via DeNB, and RN P/S-GW node transmits.
RN carries to setting up RN EPS between the RN P/S-GW at RN as a UE.At this moment, the MME of UE belongs to external network for RN.The downlink data packet of its transmission will be mapped in the EPS carrying of RN by RNP/S-GW.For the S1-AP packet that sends, the MME of UE fills out IP address into target RN with purpose IP address.Based on the IP routing mechanism, the S1-AP packet can arrive the P/S-GW node of Relay.At the P/S-GW of Relay node, can be mapped in the EPS carrying of RN as the S1-AP/SCTP bag of control plane message, pass to DeNB by GTP tunnel, and send to RN through the Un mouth.The EPS carrying of above-mentioned RN is set up by the UE function in the RN.In above process, RN P/S-GW is not to resolving through its S1-AP message of transmitting.
In this framework control plane as shown in Figure 6, the S1-U of user plane (GTP-U) ends in the P/S-GW node of RN and UE.RN handles the packet of R-UE as an eNB.All packets by the S1-U transmitting-receiving of user plane all need to transmit through the P/S-GW node of Relay.For the downstream IP bag of receiving, the P/S-GW node of UE is finished the mapping that IP wraps UE EPS carrying according to the EPS beared information of UE, and mails to RN.Packet after the mapping will be routed to RN via the P/S-GW node of Relay.The P/S-GW node of Relay is finished the mapping that UE EPS is carried to RN EPS carrying.
The embodiment of the invention is improved protocol stack architecture.
Improved control plane protocol infrastructure is that with the difference of Fig. 5 the P/S-GW node of RN has SCTP and S1AP protocol layer as shown in Figure 7, and it can resolve the S1AP message of transmitting through it between UE MME and RN.The P/S-GW of RN does not make amendment to SCTP and S1AP message.
Improved user-plane protocol framework is with the difference of Fig. 6 that as shown in Figure 8 the P/S-GW node of RN has high-rise UDP (User Datagram Protocol, User Datagram Protoco (UDP)) layer.RNP/S-GW can (the TFT parameter be all disposed in each EPS carrying accordingly, wherein contains elements such as far-end IP address, distal end slogan, local port number, protocol type according to TFT mechanism (Traffic Flow Template, Business Stream masterplate).), and resolve the beared information that S1-AP obtains.Improved user-plane protocol framework can also have the GTP-U layer.RN P/S-GW can and resolve the beared information that S1-AP obtains according to the GTP-UTEID in the packet, confirms that the UE EPS under the packet carries, and finishes the mapping of packet to RN EPS carrying.
Embodiments of the invention provide a kind of bearing mapping method, as shown in Figure 9, specifically may further comprise the steps:
High-rise AP message comprises S1AP message and X2AP message.
Below to set up process with the dedicated bearer of R-UE be example, illustrate that RN P/S-GW obtains UE EPS and is carried to mapping relations process between the RN EPS carrying from S1AP message, this process relates to two S1-AP message:
(1) (E-UTRAN Radio Access Bearer: Setup Request message evolution UTRAN RAB): this message sends to RN by UE MME to E-RAB, is used to notify the RN core net to require the E-RAB that sets up to carry the ID of (this E-RAB carrying has one-to-one relationship with UE EPS carrying) and relevant parameter.In this message, carry:
The sign of R-UE: MME UE S1AP ID and eNB UE S1AP ID;
The AMBR parameter of UE;
Wait to set up the sign and the QoS information of carrying;
Wait to set up the IP address of the up destination address of carrying: GTP-TEID and UE SGW/PGW;
(2) E-RAB Setup Response message: this message sends to UE MME by RN, and this message is used to notify the ID of the E-RAB carrying that MME RN can set up.In this message, carry:
The sign of R-UE: MME UE S1AP ID and eNB UE S1AP ID;
The sign of the carrying that success is set up;
The descending destination address of the carrying that success is set up: the IP address of GTP-TEID and RN.
At control plane: RN P/S-GW has SCTP and S1AP protocol layer, can be to resolving through its S1AP message of transmitting, and according to analysis result, the identification information and relevant qos parameter of record UE EPS carrying.Simultaneously, need to store the mapping relations between qos parameter and the RN EPS carrying in the RN P/S-GW, comprise that the core net gateway node receives core net node such as OAM (Operaion, Administration and Management, operation, administer and maintain) node, PCRF (Policy Controland Charging Rules Function, "Policy and Charging Rules Function) the carrying foundation or the bearer update message that send of mapping relations between the QoS information of node configuration and the RN EPS carrying or access network node is set up or revises the mapping relations of the QoS information of having set up between carrying with RN EPS according to described message.Thus, RN P/S-GW can set up the mapping relations that UE EPS is carried to RN EPS carrying according to relevant qos parameter.

By resolving S1-AP message, RN P/S-GW has obtained the identification information (IP/UDP+GTP-U TEID) and the QoS information of UE EPS carrying, has set up the mapping relations of identification information and RN EPS carrying; After this, be delivered to the packet of RN for each through RN P/S-GW, RN P/S-GW reads its bearing identification information, and according to the mapping relations of identification information with RN EPS carrying, packet is sent in the RN EPS carrying of correspondence.Simultaneously, RN P/S-GW can control the transmission of downlink data packet according to the QoS and the UEAMBR information that obtain.
For example: need to store the mapping relations between qos parameter and the RN EPS carrying in the RN P/S-GW: such as there being 9 kinds of qos parameters, it is corresponding one by one with it that then RN sets up 9 RN EPS carryings.RNP/S-GW is by resolving S1-AP message, know the qos parameter of newly-established UE EPS carrying, for example be the third qos parameter, then it will belong to this UE EPS data packet loaded and all be mapped in the 3rd the RNEPS carrying (what suppose the QoS3 correspondence is the 3rd RN EPS carrying).
The PDN GW node of RN has SCTP and S1AP protocol layer, and it can resolve S1AP message and the X2AP message of transmitting through it between UE MME and RN.
RN P/S-GW node obtains the identification information of newly-established UE EPS carrying, QoS information etc. by resolving S1AP message.RN P/S-GW node can also be finished the mapping that X2 is carried to RN EPS carrying by resolving X2-AP message.
Need to prove, S1-AP message and X2-AP classes of messages seemingly, just the former is used for eNB/RN and communicates by letter with MME, the latter is used for communicating by letter between eNB/RN and the eNB/RN.
Described RN P/S-GW obtains the AMBR information of UE according to the parsing to high-rise AP message, carries out downstream rate control according to described AMBR information, avoids the unnecessary wasting of resources of Un mouth.In addition, RN P/S-GW can also obtain the MBR information of UE according to the parsing to high-rise AP message, according to described MBR information the maximum downstream rate of single GBR business is controlled, and avoids the unnecessary wasting of resources of Un mouth.
At user plane: RN P/S-GW has udp layer, for its downlink data packet of transmitting of process, can be according to TFT mechanism (Traffic Flow Template, the Business Stream masterplate) (the TFT parameter is all disposed in each EPS carrying accordingly, wherein contains elements such as far-end IP address, distal end slogan, local port number, protocol type.) determine that the UE EPS under the downlink data packet carries, and finish the mapping of packet to RN EPS carrying according to the mapping relations of setting up.Simultaneously, RN P/S-GW controls the descending NGBR service rate of UE according to the descending AMBR parameter of UE.Improved user-plane protocol framework can also have high-rise GTP-U layer.Under the situation that has disposed the GTP-U layer, RNP/S-GW can be by obtaining GTP-TEID to resolving through the IP/UDP of its data packets transmitted and/or GTP-U layer, and according to the carrying of the UE EPS under the described GTP-TEID specified data bag, and finish the mapping of packet to RN EPS carrying.
