Description
Technical field
The present invention relates to the communications field, in particular to a kind of data transmission method and system.
Background technology
At Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Access) in the network, universal land radio access web (UTRAN, Universal Terrestrial RadioAccess Network) comprises radio network controller (RNC, Radio Network Controller) and base station (NodeB) two kinds of basic network elements, be commonly called as 3G network.In Long Term Evolution (LTE, Long Time Evolution) network, evolved universal land radio access web E-UTRAN comprises a kind of basic network element of evolved base station eNodeB (eNB), is commonly called as the 4G network.
Development along with the WCDMA network, high-speed downstream receiver grouping access (HSDPA, High Speed Downlink Packet Access), high speed uplink sends link packet access (HSUPA, High Speed Uplink Packet Access), two carrier wave high speed downlink packet access (DC-HSDPA, Dual Carrier-High speed downlink packet access), the two carrier wave high speed downlink packet access of two-band (DB-DC-HSDPA, Dual band-Dual carrier-high speed downlink packet access), two carrier wave high speed uplink packet access (DC-HSUPA, Dual Carrier-high speed uplink packet access), four carrier wave high speed downlink packet access (4C-HSDPA, Four carrier-high speed downlink packet access), eight carrier wave high speed downlink packet access (8C-HSDPA, Eight carrier-high speed downlink packet access) the intrasystem multi-carrier polymerizing technology of these 3G is introduced into successively, so that constantly obtaining multiplication, the up-downgoing data transmission rate of subscriber equipment (UE, User Equipment) improves.Multi-transceiver technology for above-mentioned different dimensions, take down direction as example, an important essential characteristic is: UE must be equipped with the relevant receive data processing chain (3G-Receiver Chain) of many 3G, simultaneously reception ﹠ disposal is from same sector, same base station (sector), the 3G data block that several carrier wave up-downgoings are sent.The WCDMA system that evolves to today is otherwise known as: HSPA+ system (High Speed PacketAccess+).
Development along with the LTE network, the technology CA of similar WCDMA multi-carrier polymerizing concept (carrier aggregation) also produces gradually, take down direction as example, so far, maximum can be carried out converging operationJu Hecaozuo to the carrier wave that 5 downlink bandwidths are 20MHz in the LTE system.One of them important essential characteristic is: UE must be equipped with the relevant receive data processing chain (4G-Receiver Chain) of many 4G, simultaneously reception ﹠ disposal is from same sector, same base station (sector), the 4G data block that several carrier wave up-downgoings are sent.
Operator with the HSPA+ network disposed in the long process of LTE network evolution, a very long time must be arranged, two kinds of systems exist and collaborative work simultaneously, shared from or towards the task of the transfer of data of core net one side.Such as: there are two carrier frequency point resource F1 in certain operator, and F2 F1 is distributed to the HSPA+ network operation use, and just F2 distributes to the use of LTE network operation.In its networking, only have the terminal of 3G function to work at F1, only have the terminal of 4G function to work at F2, possess simultaneously 3G, the terminal of 4G function at the same time, can only be worked at F1 or F2, can not work at F1 and F2 simultaneously.For the receiving ability that takes full advantage of this class UE with improve descending peak rate, 7G technology (3G+4G) claims that again striding HSPA+LTE system carrier aggregation technology has been born so.
At present the blank framework of 7G technology as shown in Figure 1, the master control anchor point and the data distribution control point that connect as terminal wireless resource control (RRC, Radio Resource Connection) of the base station eNB of LTE wherein.In Fig. 1, eNB utilizes the S1 interface from the MME/SGW receive data, and the data communication device of 4G is crossed the LTE system be sent to LTEUE, or LTE+HSPAaggregation UE.In the side of 3G, RNC utilizes the IU interface from the SGSN receive data, and sends it to NodeB by the IUB interface, and by NodeB the data communication device of 3G is crossed HSPDA and be sent to LTE+HSPA aggregation UE, or HSPAUE.Wherein, NodeB is connected with eNB and is connected by X2 and IUB alike interface.
Take Fig. 1 as example, Physical Downlink Control Channel (the PDCCH of UE on eNB work carrier wave, Physical Downlink Control Channel) dispatching command of the inside (as: distribute by resource, mixed automatic retransfer request (HARQ, Hybrid Automatic Repeat Request) operation relevant information) control is lower, from a part of user data of the upper reception of Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel).Simultaneously, High-Speed Shared Control Channel (the HS-SCCH of UE on NodeB work carrier wave, High Speed Shared Control Channel) dispatching command control is lower, from the upper another part user data that receives of high speed descending sharing channel channel (HS-DSCH, High Speed-Downlink Shared Channel).Anchor point eNB is responsible for the upper-layer protocol packet that eNB produces is distributed, and according to certain mode, determines which partial data bag sends from the air interface of LTE, and which partial data bag sends from the air interface of HSPA+.Be assigned to that a part of protocol data bag of NodeB, need to by new interface transmission between eNB and the NodeB, be sent according to the mode of own agreement characteristics and HSPA+ air interface by NodeB.
7G technology and HSPA+ system or the intrasystem carrier aggregation technology of LTE do not clash.That is to say: UE might do data receiver at M carrier wave of HSPA+ system, can do data receiver at N carrier wave of LTE system simultaneously again, and the work basic principle is the same, can expand to higher dimension.
The 7G polymerization technique can be fully and is utilized neatly 3G, the characteristic distributions that 4G system resource is different, in the past cross-system load balancing, switch, on the basis of the existing means such as (redirect) of being redirected, can realize to a deeper level 3G, the collaborative work of 4G system.3G, the 4G system both can share dissimilar business and (exchange (CS through the HSPA+ circuit system such as speech business as far as possible, Circuit Switch) territory, high-speed data service is as far as possible through the LTE system transmissions), also can bear simultaneously identical business (as: data service is assigned to two systems and transmits simultaneously).
But the structure that the 7G polymerization technique is corresponding has some drawbacks to need to solve, concrete, for the physical connection between NodeB and the eNodeB, because original Commercial deployment, NodeB quantity is generally very large, and connecting between each NodeB and the eNodeB all needs consumes resources.Therefore, in the large numbers of situations of NodeB, set up new physical connection fully, need to expend a large amount of resources, this almost is impossible thing.

But 3G RNC will send to 4G eNodeB from the transmitted traffic threshold value of eating dishes without rice or wine that 3G NodeB receives, but by 4G eNodeB guarantee descending shunting to the flow of 3G RNC less than the described transmitted traffic threshold value of eating dishes without rice or wine, change a saying, that is, but determine to split into the data of 3G part by the transmitted traffic threshold value of eating dishes without rice or wine of 3G.
During enforcement, 3G RNC is sent to the data of 3G after the UE via 3G NODEB, and also comprise: UE receives the data of 3G and the data of 4G, sorts according to the sequence number that identifies on each data.
The purpose of the embodiment of the invention is: propose a kind of LTE and HSPA+ carrier aggregation scene, take the 4G system as anchor point, the interface modes of 4G system and 3G system, this interface modes can carry out less modification at original structure basic schema as much as possible to be finished.
In summary, the core of the embodiment of the invention is under the spectrum aggregating scene, need to propose further, to provide and how to carry out efficient transfer of data under this new structure with the interface configuration structure between a kind of new network element.
To set forth ground clearer clearer for data transmission method that the embodiment of the invention is provided, the embodiment of the invention provides two kinds of implementations, a kind of is to shunt transmission (embodiment one) after the PDCP resume module, and a kind of is minute flow transmission (embodiment two) after RLC processes.Concrete protocol layer is processed, the embodiment that sees below.
Embodiment one
Under this transmission, the problem of the maximum that relates to is exactly the data of how to distribute 4G and 3G transmission, the method that embodiment one adopts PDCP to shunt, the structural representation of the system that relates to sees also Fig. 4, two systems independently RLC example transmit and feed back, to reach the highest data service efficiency, in addition in order to solve the sequencing problem of upper layer data, stamp sequence number (SN) by PDCP, two of UE independently after the complete data of RLC instance processes, sort according to the sequence number (SN) of PDCP.
In this example, for the mode of PDCP shunting, need to carry out following special processing:
At first, the PDCP module of 4G eNodeB is stamped sequence number to the data that receive, and is used for two RLC modules of UE side and delivers to after the PDCP module, and the PDCP layer sorts according to sequence number;
Secondly, the PDCP module of 4G eNodeB can be shunted between 4G and 3G according to certain rule, and the data that connect such as same TCP all are put into 4G or 3G, and high-priority data is put into 4G and sends, and lower-priority data is put into 3G and sends.
In addition, the PDCP module among the 4G eNodeB, the data that can also inquire about the PDCP buffering area of 4G and 3G if the data buffer storage of the buffering area of 3G is more, then can send by 4G, and vice versa.
The concrete steps of implementation data transmission method comprise as shown in Figure 5 in this example:
Step S502,4G eNodeB receive the data of S1 interface;
The GTPU module of step S504,4G eNodeB is separated frame with data, passes to the PDCP module of 4G eNodeB;
The PDCP module of step S506,4G eNodeB is stamped sequence number with data, and shunts, and the data of 4G are sent to the RLC module of 4G eNodeB, and the framing of the data communication device of 3G being crossed another GTPU module of 4G eNodeB mails to 3GRNC;
The RLC module of step S508,4G eNodeB sends the data to UE by the MAC module of 4G eNodeB;
The GTPU module of step S510,3G RNC is separated frame with data, and sends to the PDCP module of 3G RNC, and the PDCP module of 3G RNC is passed to data the RLC module of 3G RNC;
The RLC module of step S512,3G RNC mails to 3G NodeB by the HSFPFP framing of 3G RNC with data;
After the HSFP of step S514,3G NodeB (Hsdpa Frame Protocol, high-speed link grouping access Frame Protocol) separated frame, the MACEHS module by 3GNodeB mail to UE with data;
After the physical layer of step S516, UE solves data, by 2 independently the RLC module process, be aggregated into a PDCP module and sort.
Embodiment two
The method that embodiment two adopts RLC to shunt, the structural representation of the system that relates to and embodiment one are similar, specifically see also Fig. 6, for the mode of RLC shunting, need to carry out following special processing:
At first, the PDCP module of 4G eNodeB need to be stamped sequence number, is used for after the out of order delivery of RLC, and the PDCP layer need to sort;
Secondly, for the uplink state bag of rlc layer, all need all to feed back in the system of 4G, be convenient to the 4G system and retransmit as soon as possible.
And in order to reduce the out of order a large amount of feedbacks brought of RLC, need to aspect parameter configuration, limit, reduce the amount of RLC feedback, need collocating uplink state bag to forbid timer, reduce the quantity that feedback sends;
Because up data volume is generally little, therefore advise up general data all by 4G eat dishes without rice or wine send, reduce the time delay of transmitting;
The 3G side need to send to the RLC module of 4G eNodeB with the mode of the capability distribution frame that originally define with the data traffic that can send, and is used for determining by the RLC module of 4G eNodeB how many data are the RLC module to 3G RNC send.
Embodiment one has adopted two independently devices of RLC example, shunted by PDCP, the network element module of process is many comparatively speaking, and the method that embodiment two adopts RLC to shunt, flow process is more simplified, and still the while increases to some extent for the complexity of RLC module.The PDCP module of while 4G eNodeB still sequence number is numbered data, because the RLC module in this state, supports out of order delivery, when being delivered to the PDCP module of UE side, the out of order situation of data might occur still.
The concrete steps of implementation data transmission method comprise as shown in Figure 7 in this example:
Step S702,4G eNodeB receive the data of S1 interface;
The GTPU module of step S704,4G eNodeB is separated frame with data, passes to the PDCP module of 4GeNodeB;
The PDCP module of step S706,4G eNodeB is numbered data, sends to the RLC module of 4G eNodeB;
The RLC module of step S708,4G eNodeB is numbered with sequence number with data, the RLC data communication device of distributing to 4G is crossed MAC (the Medium Access Control of 4GeNodeB, the media access control) module sends the data to UE, the RLC data communication device of distributing to 3G crossed another GTPU module of 4G eNodeB and utilize after the GTPU framing transmits, transmit by X2 interface;
Therefore the GTPU module of step S710,3G RNC will be carried out special processing, and data are separated frame, because be the RLC data this moment, separate the HSFP module that can directly send to 3G RNC behind the frame and will carry out framing, then data be mail to 3GNodeB;
After the HSFP of step S712,3G NodeB separated frame, the MACEHS module by 3G NodeB mail to UE with data;
After the physical layer of step S714, UE solves data, only need independent RLC module, according to the sequence number out of order delivery of recombinating, be aggregated into a PDCP module and again sort.
Based on same inventive concept, the embodiment of the invention also provides a kind of data transmission system, and its structural representation comprises 3G RNC 801, 3G NodeB 802,4G eNodeB 803 and UE 804 as shown in Figure 8:
