Embodiment
The embodiment of the present application provides a kind of carrier aggregation transmission method and device, to realize the carrier aggregation between base station
Transmission, so as to more efficiently utilize the MPS process resource between base station so that the UE in base station edge can pass through carrier wave
The data transfer effect of polymerization lifting UE.
Technical solution provided by the embodiments of the present application, for being with load between two or more base stations in LTE system
The UE of ripple polymerizing power, reports configuration secondary cell and to activate secondary carrier by measurement, thus change can only in a base station into
Row secondary carrier configures and the present situation of activation, configured between two or more base stations, realize between base station the high level of non-agreement mouth with
High-rise, high-rise and bottom and the message communicating of bottom and bottom.
The embodiment of the present application is established from (referred to as stand between) transmission channel between base station and the configuration of UE secondary cells, removes configuration flow
Two parts illustrate.
To carry out a CA that stands, it is necessary first to the communication issue of two base stations is solved, on the interior communication problem of CA, tool
Body is described below：
First, established on transmission channel between station.
CA communications realize that driving (DD) is provided by optical fiber from ring mode (passing through signal between the direct transfer station of optical fiber) between standing
Special Ip links (IPPATH, i.e., transmit data according to ip) (CHANNEL) based on CA, and HL (i.e. layer 3 (layer3, L3)) is built
The special IPPATH of CA, medium education (Media Access functionally between newly-built station are selected during vertical data flow (FLOW)
Control, MAC) to the data channel of MAC.
The passage of MAC to MAC is made of two parts between standing：
Part I, the link establishment of CPU protocol stack aspects；
The link of CPU protocol stack aspects is established in system initialization, specifically：
A User Datagram Protocol (User Datagram Protocol, UDP) link can be only established, fixation is two-way
Port is 22000.
The link of the CPU protocol stack aspects ensures that data can correctly be sent to network processing unit (Network
Processors, NP), and receive the data that NP is forwarded.
Part II, the link establishment of NP aspects：
Sending direction link：By application protocol (Application Protocol, AP) after X2-AP link establishments success
Layer establishes sending direction link, and sending direction link is deleted by AP when X2-AP link failures；
Receive direction link：Established when (Cell) is established in logic district by AP and receive direction link, when logic district is deleted
Except when by AP delete receive direction link；
Sending direction NP is needed IP in station to being converted to interoffice IP pair, and changes ether MAC Address.Wherein, stand endogenous
IP is the IP address of station inner treater, and destination IP is the IP of NP processors.What the sending direction of NP was completed is multiple spot to a bit
Convergence forwards, therefore only needs replacing IP and ether MAC Address；
Base station receives direction, and base station indicates the designated module (MAC, RLC, PL, HL etc.) of selection designated area according to exchanging,
A point-to-multipoint data distribution is completed, can realize in theory to any one processing module of opposite end website, mainly deliver mesh
The MAC layer for wireless area.It should be noted that AP needs each module to establish two Business Streams of high and low priority
(FLOW)。
It can ensure that any pair of protocol module between any two base station is equal (predominantly between wireless MAC module) above
Can intercommunication, meanwhile, also as far as possible reduce chain travel permit number.Referring to Fig. 3, the DSP in Fig. 3 is digital signal processor (Digital
Signal Processor), each DSP supports multiple cells, a corresponding NP, as shown in figure 3, the chain between establishing base station
DSP between Lu Hou, different NP can communicate.Assuming that M base station is averaged, each base station has N number of cell to stand a CA, each
Cell data may go to P processing module.Then only need to establish 1 protocol stack aspect link in each station inner treater,
NP processors at most need to establish M-1 bar sending direction links, and N*P bars receive direction link.Cell and NP unicom, between NP
Data are exchanged, m station is exactly m NP, wants minimum link to transmit data between NP, is exactly m-1 bar links.N number of Cell and each
P processing module under Cell transmits data N*P.This is the realization of bottom, and the mode that optimum link is established can also discuss,
It can also select the man-to-man path setting modes of DSP.
The key of reducible chain travel permit number is that NP needs to carry out data exchange based on small distinctive emblem, which should be
Globally unique mark under core net, NP are exchanged and realized accordingly.In order to realize the function, defining associated cell CACell ID is
Global cell ID of some cell when opening carrier aggregation function, by evolved base station (evolved NodeB, eNB) ID words
Section, logic district id field and the joint generation of delivery module field, 32 CACell marks therein exchange foundation for NP,
Base station sends the direction of data, and peer node IP is selected according to purpose eNB ID, direction is being received, according to cell ID (Cell
ID) and (Flag) is marked to select the module delivered.
When it is default including this base station cell across station CA neighboring BS information CA cell relations tables in give the cell configuration
Across the adjacent cell of station CA, then DD need to notify AP modules establish the cell receive direction across station CA links, carry in message：It is small
Area's local ident, cell baseband processing unit (Building Base band Unit, BBU) board slot number, physical layer
(Physical Layer, PL)/wireless spread-spectrum technology (Radio Link Control, RLC)/medium education (Media
Access Control, MAC) where processor number.After AP modules receive message, by corresponding processor number with being converted to IP
Location, calls 3 links in driving interface establishment reception direction to correspond respectively to the data receiver of cell PL/RLC/MAC modules
(needing to establish high low priority both links for each module), AP modules need to preserve each of the links after link establishment success
Link identification (Link ID).
If the base station find that being at least configured with an adjacent cell across station CA in CA cell relations tables, AP modules need to obtain
The golbal ID (identity of LTE base station, 32bit numerals) and IP address information of opposite end base station, then call driving interface
Create the Link ID of the link of a sending direction and keeping link.
When the station, all cells deactivate, AP modules are received according to the cell of preservation between direction Link ID deletions station
The receiving channel of CA.
When X2 link failures, AP modules are according to CA sendaisles between the Link ID in the adjacent base station direction of preservation deletions station.
Wherein, the X2 links refer to the link that two eNB are connected directly.
When being configured without the adjacent cell across station in the CA cell relations tables in base station, AP modules need to delete all senders
To with receive direction across station CA passages.
Path Setup success between standing, after the condition for meeting to define between the base station needed for CA message communicating by oneself, according to
