Description
Technical field
The present invention relates to wireless communication technology field, more particularly to a kind of wireless signal processing methods, device and
System.
Background technology
Radio Access Network base station equipment form mainly has two kinds of integrated base station and distributed base station.So-called one
Body base station refers to baseband processing unit (BBU, baseband unit) and remote radio unit (RRU)
(RRU/RRH, radio remote unit/head) is realized in same physical equipment.Distributed base station
Middle BBU and RRU are then realized in different physical equipments respectively, pass through front end delivery interface between the two
To be communicated.The hardware platform that above-mentioned baseband processing unit is realized is also main by two types：One kind is existing
Have and more special Base-Band Processing veneer is disposed in network, mainly by Digital Signal Processing (DSP, Digital
Signal Processing) and integrated circuit (ASIC, Application Specific Integrated Circuit)
Deng composition；Another is network function virtualization (NFV, the Network of one of following evolution important directions
Function Virtualization) cloud processing platform, mainly it is made up of general and standard processor.
Usual each base band veneer monopolizes process resource on existing hardware platform, goes out once there is certain base band veneer
Existing failure, then the processing function of this base band veneer will need to be switched to be completed on other standby boards.Pass through
The active-standby switch of base band veneer can improve the reliability of equipment, extensive in the short period of time when breaking down
Multiple cell serves.
C-RAN (Centralized, Cooperative, Cloud＆Clean-Radio Access Network,
The Radio Access Network of centralization, Collaborative, cloud and green) it is that NFV is applied in wireless access network
The network design framework of (RAN, Radio Access Network) side.Under the C-RAN network architectures,
Flexibility and scalability are the main advantages of the baseband pool based on cloud processing platform.Different radio access technologies
(RAT) it is separately operable with difference in functionality processing unit on different virtual machines, by virtualizing cloud platform
Process resource shared by each virtual machine is dynamically adapted as needed.Based on virtualization cloud platform process resource
Dynamic adjustment, by dynamic migration of virtual machine can realize dynamic load leveling and shut-off economize on electricity two important work(
Energy.
So-called dynamic load leveling refers to when a certain processing node load is very heavy, or even is difficult to meet on node empty

Load) processing node on.The performance of software virtual machine can not only be better ensured that by dynamic load leveling
Demand, and it is easily achieved increase and the network capacity extension of Base-Band Processing capacity etc..So-called shut-off economize on electricity refers to work as
When virtualizing the overall load of cloud platform and being reduced by height, the process resource that correspondingly each virtual machine needs is also therewith
Decline, virtual machine is tried one's best to focus on and run on a small number of processing nodes, so that other processing nodes can be adjusted to
Dormancy or off state, and then reduce system power dissipation.Common system load is by height reduction by wireless traffic
Tidal effect causes, when such as Office Area is by the working time switching to the non-working time.In this case, although
Different virtual machines is still distributed on multiple processing nodes, but each the process resource of processing node takes
Rate is all very low.The resource utilization of baseband pool can be improved by turning off electricity-saving function, systematic function power consumption is improved
Than.
As can be seen here, one of key technology of the above-mentioned virtualization cloud platform flexibility of support and scalability is exactly
The dynamic migration of virtual machine, however inevitably occur during the dynamic migration of virtual machine it is of short duration in
It is disconnected.The break period is generally in tens to hundreds of milliseconds of the order of magnitude during virtual machine (vm) migration.In C-RAN
Under framework, the functional software run on partial virtual machine is the baseband functions processing with high real-time requires.
Above-mentioned virtual machine (vm) migration, which is interrupted, to be had an immense impact on to radio open, such as intra-cell users can not be searched for not
To cell, the ongoing business of user is interrupted.Therefore, how to ensure during virtual machine (vm) migration
It is urgent problem that radio open signal, which is not interrupted,.
In addition, monopolizing the implementation of process resource, one for each base band veneer on existing specialized hardware platform
There is single board default in denier, then in order to recover to service be accomplished by the processing function of failing single board being switched to it is other
Completed on standby board.In veneer handoff procedure, usual radio open signal can also be interrupted.If this event
There is user in the corresponding cell of barrier veneer or even have the user for carrying out business, then signal interruption can cause
The customer service for carrying out business is interrupted, and other users search the feelings of no signal occurs less than cell
Condition, it can be seen that, cell radio open signal interruption can have a strong impact on community user experience.

Embodiment one
As shown in figure 1, it is the structural representation of wireless signal processing system provided in an embodiment of the present invention,
Including the first signal processing unit 11 and secondary signal processing unit 12, first signal processing unit and
Connected between secondary signal processing unit by signal buffer unit 13, wherein：
First signal processing unit 11, for after wireless signal is received, during according to itself signal transacting

When it is implemented, if being divided according to signal transacting direction, if for example, pending
If wireless signal is downstream signal, i.e. the wireless signal that the first signal processing unit 11 is received is descending letter
Number, then the first signal processing unit 11 can be the functional process unit on virtual machine in C-RAN systems,
Can with the functional process unit on base band veneer in integrated base station system or distributed base station system,
For realizing Base-Band Processing function；Secondary signal processing unit 12 can be radio frequency correlation function processing unit,
For realizing radio frequency processing correlation function.Under this embodiment, the first signal processing unit 11 can be
The functional process unit for flexibly migrating or switching over, and secondary signal processing unit 12 can be fixation
Functional process unit.
And if pending wireless signal is upward signal, i.e., the first signal processing unit 11 is received
Wireless signal be upward signal, then the first signal processing unit 11 can handle single for radio frequency correlation function
Member, for realizing radio frequency processing correlation function, and secondary signal processing unit 12 can be C-RAN systems
The functional process unit run on middle virtual machine, can be with integrated base station system or distributed base station system
Functional process unit in system on base band veneer, for realizing Base-Band Processing correlation function.This embodiment
Under, secondary signal processing unit 12 can be the functional process unit for flexibly migrating or switching over, and
First signal processing unit 11 can be fixed functional process unit.
Preferably, when it is implemented, wireless signal processing system provided in an embodiment of the present invention can also include
3rd signal processing unit 14, it is connected to signal buffer unit 13 and realizes radio frequency processing function with being used for
Between fixing function processing unit, signal buffer unit is connected to the 3rd signal processing unit 14 in Fig. 1
Exemplified by between 13 and secondary signal processing unit.Wherein, the 3rd signal processing unit 14 can be with realizing base
The functional process unit of tape handling function completes Base-Band Processing function jointly, certainly, when it is implemented, also may be used
To be not provided with the 3rd signal processing unit 14, i.e. Base-Band Processing function completely by realizing Base-Band Processing work(accordingly
The functional process unit of energy is completed alone.
In the embodiment of the present invention, signal buffer unit 13 is located at the function treatment list that flexibly can be migrated or switch
Between member and fixed functional process unit, for connecting and isolating two functional process units.For wireless
Signal is in the write signal buffer unit 13 of the first signal processing unit 11, by the 3rd signal processing unit 14
Or secondary signal processing unit 12 is read (if any).
It is below for realizing base with the first signal processing unit 11 shown in Fig. 1 for the ease of description
The functional process unit of tape handling function, secondary signal processing unit 12 is for realizing radio frequency correlation function
Functional process unit exemplified by.
For downstream signal in the write signal buffer unit 13 of the first signal processing unit 11, by the second letter
Number processing unit 12 is read；When it is implemented, if being provided with the 3rd signal processing unit 14, then
The first signal processing unit 11 is read from signal buffer unit 13 by the 3rd signal processing unit 14 to write
Wireless signal and carry out accordingly handle after export to secondary signal processing unit 12；Upward signal is then anti-
It, i.e., in the write signal buffer unit 13 of secondary signal processing unit 12, by the first signal processing unit
11 read；When it is implemented, if being provided with the 3rd signal processing unit 14, then by the 3rd signal
Processing unit 14 reads wireless signal from signal buffer unit 13 and exported after handling accordingly to first

As can be seen here, one side signal buffer unit 13 make it that wireless signal can be in the first signal processing unit
Transmitted between 11 and the 3rd signal processing unit 14, secondary signal processing unit 12；On the other hand
So that the first signal processing unit 11 and the 3rd signal processing unit 14, secondary signal processing unit 12 are each other
Isolation, i.e., the first signal processing unit 11 only needs to be connected with signal buffer unit 13, without being related to the
Three signal processing units 14 or secondary signal processing unit 12, same 3rd signal processing unit 14 or the second
Signal processing unit 12 also only needs to be connected with signal buffer unit 13, without being related to the first signal transacting
Unit 11, thus, even if the first signal processing unit 11 does not work, as long as number in signal buffer unit 13
According to presence in the same old way, then the 3rd signal processing unit 14 and secondary signal processing unit 12 can work；Instead
It is as the same.
Radio open signal includes main two classes signal：One class be for providing the signal that cell is covered substantially,
Such as reference signal, synchronizing signal and broadcast singal；Another kind of is the control sum for providing user service
It is believed that number.It is the fundamental mark that cell is present for first kind signal, once first kind signal on radio open
Interrupt, then cell is covered and is just not present substantially, i.e., cell is disappeared.In different wireless communication technology
((forth generation is moved by such as 2G (Generation Mobile Telecommunication System technology), 3G (3rd generation mobile communication technology), 4G
The dynamic communication technology), 5G (the 5th third-generation mobile communication technology) etc.), when cell is set up, basic parameter is assigned
It is worth (such as cell ID, bandwidth), otherwise then first kind signal is changeless, otherwise it is according to one
Fixed cycle conversion.Therefore, storable size of data should comprise at least one in signal buffer unit 13
The first kind signal (or cell covers signal substantially) of individual complete cycle (i.e. the period of change of first kind signal).
For Equations of The Second Kind signal, inherently exist in different wireless communication technology and transmit incorrect situation, if
The data format of upper Equations of The Second Kind signal of eating dishes without rice or wine meets wireless communication protocol standards, although data content therein is wrong
By mistake, the significant impact of service disruption etc will not be also produced to system.Therefore, in signal buffer unit 13
The form of the Equations of The Second Kind signal of storage must be correct.
Signal buffer unit 13, which is introduced, based on this, in the embodiment of the present invention may be such that the first signal processing unit
There is isolation between 11 and the 3rd signal processing unit 14, secondary signal processing unit 12, each other can be only
Vertical work.It is defined by the size of data to being cached in signal buffer unit 13 and buffering characteristics of signals
Afterwards, when the first signal processing unit 11 is in the off position of migration or switching, the 3rd signal transacting
Unit 14 and secondary signal processing unit 12 still can chronologically read the number in signal buffer unit 13
According to there is provided continual radio open signal.The process for migrating or switching in the first signal processing unit 11
In, cell covers signal and not interrupted completely substantially, carries out the user of business, and user service will not be interrupted,
But performance may be declined slightly.
In order to be better understood from the embodiment of the present invention, below with the wireless of the first signal processing unit 11 reception
Signal is exemplified by downstream signal, the specific implementation process to the embodiment of the present invention illustrates.
As shown in Fig. 2 it is the schematic flow sheet that is handled downstream signal in the embodiment of the present invention.Letter
Number buffer unit 13 can store N number of TTI (transmission time interval, Transmission Time Interval, N
For natural number) downstream signal, downstream signal herein includes all downlink data and information.
Each TTI data are stored in the diverse location of signal buffer unit 13.First signal processing unit
Each TTI data are written to it in 13 pairs of signal buffer unit by 11 according to the signal transacting sequential of its own
The position answered, it is each TTI pairs in signal buffer unit 13 after N number of TTI since starting system
The position answered all has stored correct protocol stack data.As the first signal processing unit 11 processing generation N+1
After individual TTI data, corresponding data are write into the corresponding positions of this TTI, then this TTI data
Just updated, be still now the data of upper a cycle on other N-1 TTI positions, subsequently,
First signal processing unit 11 is respectively processed according to the wireless signal received obtains corresponding data simultaneously
Relevant position in signal buffer unit is updated.3rd signal processing unit 14 or the second letter
Number processing unit 12 reads each TTI data according to the sequential of its own and completes relevant treatment, according to sky
Mouth timing requirements send radio open signal.
When the first signal processing unit 11 is under normal mode of operation, as long as the first signal processing unit 11
The more new signal buffer unit before the 3rd signal processing unit 14 or secondary signal processing unit 12 read data
Corresponding TTI data in 13, then radio open signal is then completely correct.When the first signal processing unit
11 under migration or switch mode, i.e., when the first signal processing unit 11 can not carry out wireless signal processing,
First signal processing unit 11 can not all update the data that buffering is gone in time T.In T time, the
Three signal processing units 14 or secondary signal processing unit 12 take still according to the signal transacting sequential of its own
The data of signal buffer unit 13, and send to radio open.In this state, radio open data
Form be it is correct, with when constant or periodic cell to cover signal substantially be correct, but user
The content of control and data-signal is the content of renewal before the first signal processing unit 11 is migrated.So at this
Under the mechanism of one radio open reproducing signals, it is ensured that radio open signal is uninterrupted, it is ensured that cell is basic
Covering.
As can be seen here, if the signal that the first signal processing unit is received is downstream signal, in order to ensure the
One signal processing unit carries out function migration or handoff procedure interrupts wireless signal, then signal caching is single
At least need to store the downstream signal in preset duration in member 13, the preset duration can be according to actual needs
It is configured, depends primarily on the period of change of wireless first kind signal.For example, it is assumed that wireless communication system
TTI (transmission time interval, Transmission Time Interval) time span is TTTI, it is foregoing wireless
The period of change of first kind signal is N*TTTI, the break period up to T for migrating or switching, then signal
Buffer unit 13 needs the downstream signal duration stored to be just N*TTTI.Further by taking LTE system as an example,
One TTI length is TTTI=1ms (millisecond), in addition to the System Frame Number in broadcast channel (PBCH) before
The cycle for stating first kind wireless signal variation is 10*TTTI=10ms, if needed for function migration or switching most
It is for a long time 40ms, then preset duration is set to 10ms, then in signal buffer unit 13 extremely
10 TTI of caching downstream signal is needed less.
And for upward signal, upward signal can be stored in signal buffer unit 13, the upward signal bag
Include in all uplink receiving data, the embodiment of the present invention, for that can be stored in signal buffer unit 13
Upward signal size do not limit.Because, the unit of upward signal is received to realize radio frequency processing work(
The fixing function processing unit of energy, its processing function will not be migrated or switched, therefore it may only be necessary to will receive
To upward signal write signal buffer unit 13 in, the then functional process unit by that can migrate
The data read in signal buffer unit 13 are handled.In the normal mode of operation, fixed work(
As long as can processing unit more new signal caching list before transportable or switching functional process unit reads data
Corresponding TTI data in member 13.And it is transportable or switching functional process unit be in migration or
Under switch mode, the data that fixed functional process unit can as before in more new signal buffer unit 13,
Simply transportable or switching functional process unit can not read data in time and be handled, standby function migration
Or after the completion of switching, the functional process unit after switching continues to read data and handled.
In wireless signal processing methods provided in an embodiment of the present invention, wireless base station is divided into transportable or switching
Functional process unit and it is not transportable or switching functional process unit；On this basis, it is situated between
Addition signal buffer unit is attached and isolated；Corresponding wireless signal processing methods are provided based on this,
Ensure that radio open signal is not interrupted during partial function is migrated or is switched；And if wireless signal is
Downstream signal, then need corresponding setting signal buffer unit data storage size, it is ensured that cell is covered substantially
Signal is correct, effectively improves systematic function in function migration or handoff procedure.
