Reference picture 2, Fig. 2 is the 4G Single Frequency Network dilatation flow charts of the embodiment of the present invention, below to the present invention
4G dilatation flows in embodiment are described in detail.
As shown in Fig. 2 4G Single Frequency Network dilatation flows mainly include：Scene Recognition, business model identification and
Dilatation is adjudicated.By the implementation to key node in flow, the dilatation that can carry out current network is implemented.Tool
Body：
1) scene Recognition
Scene is broadly divided into two major classes：One class refers to big traffic scene, such as colleges and universities, stadium, Conference Room
It is mainly shown as that data business volume is high or number of users is more Deng, such scene；It is another kind of to refer to routinely dilatation scene,
Such scene service shows more stable, such as city hot spot region.
2) business model is recognized
For big traffic scene (bursts of traffic scene), consider whether that a large number of users is accessed first, accessing user
Number is more, then carries out carrier wave dilatation, access customer number is few but portfolio is big, then it is contemplated that carrying out veneer dilatation.
For routinely dilatation, busy is paid close attention to per RAB flows, busy can pass through 4G per RAB flows
Webmaster is obtained.By being made decisions to busy per RAB flows, business can be divided into big bag model, middle bag
Model (between parcel and big bag) and parcel model.
3) dilatation is adjudicated
The object of dilatation judgement mainly includes three major types, i.e. number of users, busy PRB utilization rates and busy list
Cell flow, when three standards reach decision threshold simultaneously, performs carrier wave dilatation or optimization.
4G Single Frequency Network dilatation flows are described below：
Dilatation is the dilatation perceived based on user, by large-scale websites such as Sina, Sohu, Netease and Tengxuns
Move broadband services (MBB, Mobile Broadband) web page browsing test and analysis is drawn, page
Face browses time delay and is inversely proportional with number of users, and webpage is opened speed and is inversely proportional with number of users, extracts 9 points to 10
The business datum of point shows that business experience is higher than experience baseline after 9: 20；Passed by MBB test files
Defeated agreement (FTP, File Transfer Protocol) downloads descending throughput and user in display, cell in real time
It is inversely proportional.
For 2G, 3G network dilatation, it need to only consider that single " resource utilization " carries out dilatation, for
For the data service dilatation of 4G networks, single " resource utilization " can not characterize the demand of capacity completely, need
Business is classified, the angle perceived from user is analyzed, it is considered to which PRB utilization rates, RRC connect
Connect number of users, up-downgoing flow, the factor of influence such as maximum number of user in cell.
From business angle analysis, business can be divided into parcel model, middle bag model and big bag model, it is different
Business scenario dilatation thresholding is different, it is necessary to which the dimension considered is also different, such as big bag model needs to consider
PRB utilization rates, effective RRC connection numbers of users and flow, and parcel model lays particular emphasis on the effective RRC of consideration
Number of users is connected, with reference to table 1, table 1 gives condition and the suggestion of all kinds of business dilatations.
Table 1
For big bag business (business correspondence big bag model), such as video, user focus more on buffer time and
Play interim card number of times；For packet services (business correspondence parcel model), for example WEB is browsed, Yong Hugeng
Pay attention in page load time.Research shows that more than 95% experimenter keeps good notice within 2 seconds,
Notice starts to disperse after 3 seconds, i.e., period of reservation of number, which is less than, means outstanding network in 3 seconds.
Big bag (video) business takes a large amount of physical resources due to single user, and 30 feelings are not up in number of users
Just occurring that utilization rate surges under condition brings user rate to decline to influence service-aware, it is therefore desirable to comprehensive
Consider the influence that number of users PRB utilization rates and Zone are perceived to user.Research shows, big bag business
Dilatation thresholding is：Descending PRB utilization rates are more than or equal to 40% and cell flow is more than 2.8GB and RRC has
Effect connection number of users is more than 12.
Middle bag business (bag model in business correspondence) is that big bag and packet services mixing proportion of composing are not known,
Therefore in dilatation assessment, in scape cell capacity-enlarging standard of making a block booking have two kinds：
1) dilatation based on Consumer's Experience：Middle bag scene perception dilatation thresholding：User rate 3.2M, PRB
Utilization rate 42%, flow 3GB, effective RRC connections number of users 17；
2) dilatation based on network carrying ability：When cell maximum number of user is more than 150, in make a block booking scape
Lower customer service is perceived and network carrying ability has deteriorated, it is proposed that dilatation.
Number of users is excessive but the not high region of portfolio, because network insertion carrying (signaling side) is limited,
User's access is difficult, it is more to go offline, and the perception to user causes more ill effect, therefore, parcel industry
Business dilatation emphasis considers access customer number.Under parcel scene, when user (including number is passed and non-number passes number of users)
During more than 160, user's web traffic time delay perceives thresholding significantly more than 3s and fluctuation increases, it is proposed that
Carrier wave dilatation is considered when community user number is more than 160.Therefore, the dilatation algorithm of 4G Single Frequency Network can be with
Summarize as shown in Figure 3.
It can be seen that, the dilatation flow of the embodiment of the present invention includes：It is identified according to the affiliated scene in specific base station
Classification；For common application scene, analyzed according to every RAB flows, if being more than per RAB flows
Whether big 0.2MB, then averagely connect number, PRB utilization rates and flow according to big its RRC of bag model analysis
In threshold value, if then carrying out dilatation, if being less than 0.2MB per RAB flows, according to parcel model analysis
Whether its RAB maximum number of connections is more than threshold value, if then carrying out dilatation；For campus, stadium and meeting
The big traffic scene such as room, then to base station, maximum activation number of users reaches the carry out hardware dilatation of threshold value simultaneously, right
RRC connections maximum number of user reaches the carry out carrier wave dilatation of threshold value；So far the volume reduction flow to TDS is triggered,
To confirm the majority of the frequency available for TDL.
Reference picture 4, Fig. 4 is the TDS network volume reduction flow charts of the embodiment of the present invention, below to of the invention real
The TDS network volume reduction flows applied in example are described in detail.
After TDL dilatation demand statistics is completed, the volume reduction for proceeding by TDS is calculated.
Mobile regulation A frequency range 15M bandwidth (2010MHz~2025MHz) is distributed to TDS and used, and presses
According to every carrier bandwidths 1.6MHz requirements, A frequency ranges maximum configured is 9 carrier waves.Part hot spot region is due to connecing
Access customer is more, and business scale is big, and the carrier wave of A frequency ranges 9 can not meet demand, thus enable F-band
1905MHz~1915MHz supplements frequency range as TDS, and 10MHz bandwidth brings 6 carrier capacities.TDS
Frequency range divides as shown in Figure 5.
With deployment of LTE network, TDS business is gradually decreased, and carrier frequency resource utilization rate is begun to decline, F frequencies
The TDS carrier waves of section, which can clear up and discharge, supports LTE business development demands, effectively lifting frequency range utilization rate.
As shown in figure 4, TDS network volume reductions flow is main from F-band carrier wave configuring condition and TDS network industries
From the aspect of quality two of being engaged in, by the research to key node in flow, the F to current TDS networks is realized
The implementation that frequency range carrier wave is cleared up and discharged.
1) carrier wave is configured
A frequency ranges support maximum 9 carrier wave configuration, it is generally the case that main carrier is configured to A frequency ranges.Therefore,
Can 8 pieces of A frequency range secondary carriers of maximum configured.When the secondary carrier configuration of TDS cells is less than or equal to 8 pieces, A
Frequency range can meet configuration needs with 100%, only the F-band carrier wave of occupancy need to be configured into A frequency ranges；
When the secondary carrier configuration of TDS cells is more than 8 pieces, TDS cell carriers must can use F-band, therefore,
When clearing up and discharging F-band carrier wave, it is necessary to consider the operational indicator and Consumer's Experience of TDS cells.
2) GTL interoperates
GTL interoperability is the interoperability between LTE, TDS and GSM.
The overlay area of current LTE network has been over the covering of TDS networks, it may be considered that close LTE
Network retains TDS to LTE gravity treatment and redirection function to the redirection function of TDS networks, so that
Reduction business is resident the ratio of TDS networks, and support TDS volume reductions are implemented.
Based on the interoperability strategy of existing network, carry out LTE to TDS interoperability and simplify；
LTE is not redirected to TDS not gravity treatments；TDS remains into LTE gravity treatment and redirects strategy；
LTE to GSM opens gravity treatment and blind redirection；GSM is opened into LTE gravity treatment, no longer passes through
TDS is bridged；
3) frame point
Frame point mainly includes descending 2 times of frames point, descending 4 times of frames and divided and up 2 times of frames point.Descending 2 times of frames
Point multiplexing is the adjoint DPCH codes resource for 2 SF=16 that every 2 users are multiplexed on TS6 jointly under
Row is with channel；Open descending 4 times of signaling frame division multiplexings and open up 2 times of traffic frame timesharing, and configure
DCCC parameters, can now allow up reduction of speed to 8k, and take 2 simultaneously with another up 8K user
Individual SF16 code channels, are carried on TS1 or TS2；2 SF=16 of occupancy that each upstream rate is 16k
Code resource, each upstream rate for 32k 4 SF=16 of occupancy code resource, upstream rate is 64
8 SF=16 of Shi Zhanyong code resource, it is 64k that maximum uplink rate is set at present.
4) service rate downshifts
The characteristics of service rate downshift is directed to business, turns down class, reduction connects by service access guarantee speed
Enter the resource occupation of business.The current minimum access rate of such as video traffic is 64K, when by access rate
When being reduced to 16K, unnecessary resource is supplied to other users to access.
5) carrier bandwidths compress technique
Current carrier bandwidths are 1.6MHz, can be compressed to carrier bandwidths by carrier wave compress technique
1.4MHz, its advantage is to add 1 piece of carrier wave on the premise of A frequency range 15MHz bandwidth, totally 10 pieces of loads
Ripple, its shortcoming is the increase in the interference potential of intercarrier, has an impact to quality of service.
It can be seen that, the volume reduction flow of the embodiment of the present invention includes：If the configuration of TDS cells secondary carrier is less than or equal to 8
Block, and there is carrier wave to be configured to F-band, then, the F-band carrier wave of the cell can be all replaced into A
Frequency range；If the configuration of TDS cells secondary carrier is more than 8 pieces, when clearing up and discharging F-band carrier wave, it is necessary to consider user
Experience and service impact, with reference to skills such as GTL interoperability, frame point, access rate downshift, carrier bandwidths compressions
Art and means are waited to implement；Therefore, for TDS cells, the F-band within 8 pieces of carrier waves of clearing up and discharging first is carried
Ripple (is replaced into A frequency ranges), for configuring the cell more than 8 pieces of carrier waves, it is necessary to reference to the business mould of cell
Type takes frame point, service rate downshift and GTL interoperability to coordinate F-band to clear up and discharge.
