Description
Technical field
The present invention relates to the communications field, in particular to a kind of data transmission method and system.
Background technology
In WCDMA (WCDMA, Wideband Code Division Multiple Access) network, logical
Wireless network is included with land radio access web (UTRAN, Universal Terrestrial Radio Access Network)
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 includes
A kind of basic network element of evolved base station eNodeB (eNB), is commonly called as 4G network.
Along with the development of WCDMA network, high-speed downstream receives link packet and accesses (HSDPA, High Speed
Downlink Packet Access), high speed uplink send link packet access (HSUPA, High Speed Uplink
Packet Access), dual carrier high-speed slender body theory (DC-HSDPA, Dual Carrier-High speed
Downlink packet access), two-band dual carrier high-speed slender body theory (DB-DC-HSDPA, Dual band-
Dual carrier-high speed downlink packet access), dual carrier high speed uplink packet access (DC-
HSUPA, Dual Carrier-high speed uplink packet access), four carrier wave high-speed slender body theory
(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) these 3G intrasystem
Multi-carrier polymerizing technology is introduced into successively so that the up-downgoing data transmission rate of subscriber equipment (UE, User Equipment)
It is continuously available multiplication to improve.For the multi-transceiver technology of above-mentioned different dimensions, as a example by down direction, an important spy substantially
Levy and be: UE must be equipped with reception data relevant for a plurality of 3G and processes chain (3G-Receiver Chain), can receiving area simultaneously
Reason is from same sector, same base station (sector), and several carrier wave up-downgoings send the 3G data block of coming.Evolve to the present
It WCDMA system is otherwise known as: HSPA+ system (High Speed Packet Access+).
Along with the development of LTE network, the technology CA (carrier of similar WCDMA multi-carrier polymerizing concept
Aggregation) the most gradually producing, as a example by down direction, so far, in LTE system, maximum can be to 5 downlink bandwidths
Carrier wave for 20MHz carries out converging operationJu Hecaozuo.One of them important basic feature is: UE must be equipped with relevant the connecing of a plurality of 4G
Receive data and process chain (4G-Receiver Chain), process can be received from same sector, same base station simultaneously
(sector), several carrier wave up-downgoings send the 4G data block of coming.
In operator by the HSPA+ network disposed towards in the long process of LTE network evolution, when necessarily having the longest one section
Between, two kinds of systems exist and collaborative work simultaneously, shared from or towards core net side data transmit
Task.Such as: there are two carrier frequency point resources F1, F2 in certain operator, F1 is distributed to HSPA+ network operation and uses, and just
F2 distributes to LTE network operation and uses.For in its networking, the terminal of only 3G function can only work on F1, only 4G merit
Can terminal can only work on F2, be provided simultaneously with the terminal of 3G, 4G function, at the same time, can only be on F1 or F2
Work, it is impossible to simultaneously work on F1 and F2.So in order to make full use of the receiving ability of this class UE and improve down peak magnitude
Speed, 7G technology (3G+4G) is born also known as across HSPA+LTE system carrier aggregation technology.

Main control anchor point that (RRC, Radio Resource Connection) connects and data flow-dividing control point.In FIG, eNB profit
At MME/SGW, receive data with S1 interface, the data of 4G are sent to LTE UE by LTE system, or LTE+HSPA
aggregation UE.In the side of 3G, RNC utilizes IU interface to receive data from SGSN, and is sent it to by IUB interface
The data of 3G are sent to LTE+HSPA aggregation UE by HSPDA by NodeB by NodeB, or HSPA UE.
Wherein, it is attached by X2and IUB alike interface between NodeB and eNB.
As a example by Fig. 1, UE Physical Downlink Control Channel (PDCCH, Physical on eNB operating carriers
Downlink Control Channel) the inside traffic order (such as: resource distribute, hybrid automatic repeat-request (HARQ,
Hybrid Automatic Repeat Request) operation relevant information) control under, from Physical Downlink Shared Channel (PDSCH,
Physical Downlink Shared Channel) a part of user data of upper reception.Meanwhile, UE carries in NodeB work
The traffic order control of the High-Speed Shared Control Channel (HS-SCCH, High Speed Shared Control Channel) on ripple
Under system, from the upper reception of high speed descending sharing channel channel (HS-DSCH, High Speed-Downlink Shared Channel)
Another part user data.The upper layer protocol data bag that anchor point eNB is responsible for eNB to produce is allocated, according to certain mode,
Determining which part packet sends from the air interface of LTE, which part packet sends from the air interface of HSPA+.Allocated
To the protocol data bag of that part of NodeB, need to be transmitted by between eNB and NodeB new interface, by NodeB according to
The mode of oneself agreement feature and HSPA+ air interface is transmitted.
Carrier aggregation technology in 7G technology and HSPA+ system or LTE system does not clash.That is: UE
Likely on M carrier wave of HSPA+ system, do data receiver, data can be done on N number of carrier wave of LTE system again simultaneously and connect
Receiving, work ultimate principle ibid, can be extended to higher dimension.
7G polymerization technique can be fully and be flexibly utilized by the characteristic distributions that 3G, 4G system resource is different interdepartmental in the past
System load balancing, switching, redirect on the basis of existing means such as (redirect), it is possible to realize 3G to a deeper level, 4G
The collaborative work of system.3G, 4G system both can share different types of business (such as speech business as far as possible through HSPA+ system electricity
Exchange (CS, Circuit Switch) territory, road, high-speed data service transmits through LTE system as far as possible), it is also possible to undertake identical simultaneously
Business (such as: data service is assigned to two systems and transmits simultaneously).
But the structure that 7G polymerization technique is corresponding have some drawbacks need solve, concrete, for NodeB and eNodeB it
Between physical connection, due to original Commercial deployment, NodeB quantity is general the biggest, sets up and connect between each NodeB and eNodeB

Data transmission method for the embodiment of the present invention being provided becomes apparent from clearer with illustrating, the embodiment of the present invention provides
Two kinds of implementations, one is to carry out shunting transmission (embodiment one) after PDCP resume module, and one is to process it at RLC
After carry out shunting transmission (embodiment two).Concrete protocol layer processes, the embodiment seen below.
Embodiment one
Under this transmission, the maximum problem related to is how to distribute 4G and the 3G data of transmission, embodiment one
Using PDCP to carry out the method shunted, the structural representation of the system related to refers to Fig. 4, the RLC example of two system independences
It is transmitted and feeds back, to reach the highest data service efficiency, in addition to solve the sequencing problem of upper layer data, by
PDCP stamps sequence number (SN), after two independent complete data of RLC instance processes of UE, arranges according to the sequence number (SN) of PDCP
Sequence.
In this example, for the mode of PDCP shunting, need to carry out following special handling:
First, the data received are stamped sequence number by the PDCP module of 4G eNodeB, and for two, UE side, RLC module is delivered
After PDCP module, PDCP layer is ranked up according to sequence number；
Secondly, the PDCP module of 4G eNodeB can shunt between 4G and 3G according to certain rule, such as same
The data of one TCP connection are all 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 out
Send.
It addition, the PDCP module in 4G eNodeB, it is also possible to the data of the PDCP relief area of inquiry 4G and 3G, if
The data buffer storage of the relief area of 3G is more, then can be transmitted by 4G, and vice versa.
This example is implemented the concrete steps of data transmission method as it is shown in figure 5, include:
Step S502,4G eNodeB receive the data of S1 interface；
Data are carried out solving frame by step S504, the GTPU module of 4G eNodeB, pass to the PDCP module of 4G eNodeB；
Data are stamped sequence number, and are shunted by step S506, the PDCP module of 4G eNodeB, the data of 4G are sent out
Give the RLC module of 4G eNodeB, the data of 3G are mail to 3G by the framing of another GTPU module of 4G eNodeB
RNC；
Step S508, the RLC module of 4G eNodeB send the data to UE by the MAC module of 4G eNodeB；
Data are carried out solving frame by step S510, the GTPU module of 3G RNC, and are sent to the PDCP module of 3G RNC, 3G
Data are passed to the RLC module of 3G RNC by the PDCP module of RNC；
Step S512, the RLC module of 3G RNC pass through the HSFP FP framing of 3G RNC, and data mail to 3G NodeB；
Step S514, the HSFP (Hsdpa Frame Protocol, high-speed link packet accesses Frame Protocol) of 3G NodeB
After solving frame, by the MACEHS module of 3GNodeB, data are mail to UE；
After step S516, the physical layer of UE solve data, processed by 2 independent RLC module, be aggregated into one
PDCP module is ranked up.
Embodiment two
Embodiment two uses RLC to carry out the method shunted, and the structural representation of the system related to is similar with embodiment one,
Specifically refer to Fig. 6, for the mode of RLC shunting, need to carry out following special handling:
First, the PDCP module of 4G eNodeB needs to stamp sequence number, after the out of order delivery of RLC, PDCP layer need into
Row sequence；
Secondly, for the uplink state bag of rlc layer, it is required for feeding back in the system of 4G, it is simple to 4G system is as early as possible
Ground is retransmitted.
And in order to reduce the out of order a large amount of feedbacks brought of RLC, need to limit in terms of parameter configuration, reduce RLC
The amount of feedback, needs collocating uplink state bag to forbid intervalometer, reduces the quantity that feedback sends；
Owing to up data volume is the most little, it is therefore proposed that up general data all pass through 4G eat dishes without rice or wine carry out send out
Send, reduce the time delay forwarded；
