Embodiment, is briefly described to related content below for a better understanding of the present invention：

Subframe proportioning 1U3D can be：DSUDDDSUDD；Subframe proportioning 2U2D can be： DSUUDDSUUD.Following cross time-slots for referring to refer to subframe #3 and #8.1U3D subframes #3 It is descending sub frame with #8,2U2D subframes #3 and #8 are sub-frame of uplink, under 2U2D subframe proportionings Interference check function is opened, the reception interference work(of sub-frame of uplink subframe #2, #3, #7, #8 is detected Rate (i.e. following Interference Detection values), the significantly raised feelings of the jamming power in subframe #3 and #8 Under condition, the interference of the base station for coming from 1U3D subframe proportionings is determined with.

Fig. 1 shows the dynamic TDD subframes proportioning regulation method that one embodiment of the invention is provided Schematic flow sheet, as shown in figure 1, the dynamic TDD subframes proportioning regulation method of the present embodiment is such as It is lower described.

101st, webmaster receives the service rate that each base station reports, and the base station is that 1U3D is sub Frame proportioning, and belong to the base station of the first networking.

For example, webmaster connects all base stations in the first networking, and the webmaster receives each base The service rate that station reports, can be specially：Webmaster receives the uplink service speed that each base station reports Rate and downlink business speed；Uplink service speed and downlink business speed at this can exist for base station The polydispersity index value of (i.e. in a period of time) uplink and downlink in one cycle.For example, base station exists In measurement period, periodic sampling evolved base station (evolved Node B, abbreviation eNB) is eated dishes without rice or wine PDCP layer up-downgoing service rates, add up in measurement period PDCP of eating dishes without rice or wine (Packet Data Convergence Protocol, abbreviation PDCP) layer up-downgoing service rate is not It is zero sampled value, accumulated value is divided by accumulative frequency, acquisition up-downgoing service rate.

The sustainable up-downgoing service rate counted in the base station in base station, for up-downgoing business speed Reporting for rate is lasting.

In a particular application, base station can carry out pretreatment to the up-downgoing service rate for counting, and enter And can report to webmaster.For example, pretreatment is appreciated that base station by the up-downgoing business of high-rise statistics Speed in the mode of Operation and Maintenance (Operation＆Maintenance, abbreviation OM) message or It is that the mode of file collects, reports webmaster.

102nd, the service rate that webmaster is reported according to all base stations, judges own in the first networking Whether the business throughput of base station reaches the first handoff threshold, if it is, execution step 103, no Then, repeat step 101.

Business throughput in the present embodiment can be uplink business data amount and downlink service data Amount, the uplink business data amount refer to the statistics of the uplink service speed of all base stations in the first networking, Downlink service data amount refers to the statistics of the downlink business speed of all base stations in the first networking.

In the present embodiment, the uplink service speed of all base stations in the first networking can be entered by webmaster Row is cumulative, obtains uplink business data amount, and the downlink business speed of all base stations is carried out It is cumulative, obtain downlink service data amount；

And then can determine whether the uplink business data amount whether more than upstream traffic high load capacity door Limit, and judge the downlink service data amount whether less than downlink traffic high load capacity thresholding.

It should be noted that the above-mentioned upstream traffic high load capacity of aforesaid first handoff threshold correspondence Thresholding and downlink traffic high load capacity thresholding.Above-mentioned upstream traffic high load capacity thresholding and descending Portfolio high load capacity thresholding can be preset according to actual needs.

If the 103, in step 102, the business throughput of all base stations of the first networking reaches One handoff threshold, then to all base stations of the first networking send for realize subframe proportioning switching and For opening the first instruction of interference check function, so that all base stations are according to the described first instruction Subframe proportioning is switched to into the subframe proportioning of 2U2D, and opens interference check function.

In this step, in the first networking, the business throughput of all base stations reaches the first switching door Limit, can be specially：

The webmaster determines uplink business data amount more than upstream traffic high load capacity thresholding, and under Industry business data volume is less than downlink traffic high load capacity thresholding.

104th, webmaster is disturbed whether serious base station number reaches in judging all base stations Second handoff threshold, if it is, execution step 105, otherwise, execution step 106；

If the 105, being disturbed serious base station number in step 104 in all base stations reaches Two handoff thresholds (as shown in Figure 3 B), then to all base stations send realize subframe proportioning switching and For closing the second instruction of interference check function, so that all base stations are according to the described second instruction Subframe proportioning is switched to into the subframe proportioning of 1U3D, and closes interference check function.

If the 106, being disturbed serious base station number to be not up in step 104 in all base stations Second handoff threshold (as shown in Figure 3A), then send for controlling to each base station being disturbed The notification instruction that UE is accessed, so that interfered base station controls the base station according to notification instruction UE is accessed.

For example, call access control is opened after notification instruction is received in base station, controls new User accesses and sets up new carrying；Load balancing function can be opened makes the original user of this cell simultaneously It is distributed to.

107th, the service rate that webmaster is reported according to undisturbed base station in the first networking, sentences Whether the business throughput of disconnected undisturbed all base stations reaches the 3rd handoff threshold, if it is, Execution step 108, otherwise, execution step 104.

It will be appreciated that can be counted according to Interference Detection value wipe-out mode in this step 107. All base stations all report Interference Detection value and up-downgoing business datum amount.If -yl in the first networking Interference Detection of standing value is not higher than the first predetermined threshold value, then webmaster counts its up-downgoing business datum The up-downgoing business datum amount of the i.e. cumulative base station of amount, if being higher than the first predetermined threshold value, does not unite Count the up-downgoing business datum of the base station that the up-downgoing business datum amount of the base station does not add up Amount.

The first predetermined threshold value at this is the interference inspection reported to base station that webmaster side pre-sets The thresholding judged by measured value, the thresholding are used for judging that be disturbed whether being in base station does not affect The normal level of base station performance.

If the 108, in step 107, the business throughput of undisturbed all base stations reaches Three handoff thresholds, then send to all base stations and realize the switching of subframe proportioning and for closing interference inspection Second instruction of brake, so that subframe proportioning is switched by all base stations according to the described second instruction For the subframe proportioning of 1U3D, and close interference check function.

For above-mentioned step 107, can be illustrated below：

Citing：When the subframe proportioning of base station is 2U2D, the up peak speed of each cell is about 20Mbps, descending peak speed are about 80Mbps.Business high load capacity thresholding can be set to peak speed 80% or so.In the case of specific to indoor networking, if individual 10 cell (0-9) networking and all little Area is interference-free, then the uplink service high load capacity thresholding of network is 20Mbps*10*80%=160Mbps, downlink business high load capacity thresholding is 80Mbps*10*80%=640Mbps；

If wherein 2 cells of 10 cell networkings are disturbed, the uplink service high load capacity of network It is 20Mbps* (10-2) that thresholding is the uplink service high load capacity thresholding of then network * 80%=128Mbps, downlink business high load capacity thresholding are 80Mbps* (10-2) * 80%=512Mbps.Business high load capacity thresholding becomes with the change of interference effect base station number Change.

If wherein cell 0 and cell 1 are disturbed (interference value is disturbed thresholding more than judgement), Then webmaster only adds up and counts the service rate of cell 2-9, and the statistical value is received with above-mentioned two cell (upper behavior business high load capacity thresholding is 20Mbps* (10-2) to the business high load capacity thresholding of interference * 80%=128Mbps, downlink business high load capacity thresholding are 80Mbps* (10-2) * 80%=512Mbps) it is compared and judges.

In said method, TDD subframe proportionings are switched to 2U2D from 1U3D in dynamic by base station When, the interference at crossed slot (i.e. following Interference Detection values) being subject to is detected, during according to intersecting Whether gap Interference Detection value is judged under 2U2D sub-frame configurations to residing in, so as to avoid It is switched under 2U2D subframe proportionings when base station is based only upon upstream traffic, it is dry by cross time-slot Disturb caused service exception.In addition, indoors in the case of base station networking, webmaster is by judging The indoor base station Interference Detection value being disturbed and the indoor base station quantity being disturbed, can ensure Realize being matched somebody with somebody by the dynamic TDD subframes of 1U3D to 2U2D in the case of rationally lifting uplink service Than adjustment, cannot be with reference to the Interference Detection value of indoor base station and by dry in solving prior art Disturb indoor base station quantity and realize dynamic TDD subframe proportioning of the subframe proportioning by 1U3D to 2U2D The problem of adjustment.

It will be appreciated that after in above-mentioned steps 103, base station receives the first instruction, can open Interference check function, i.e., in such scheme, under 2U2D subframe proportionings, base station can be held for base station Interference check function is opened, that is, is supported in up guiding time slot (Uplink Pilot Time Slot, letter Claim UpPTS) single symbol and sub-frame of uplink on measure frequency domain on per 12 continuous subcarriers Upper (12 Resource Units (Resource Element, abbreviation RE)) total uplink interference power And report operation maintenance center (Operation＆Maintenance Center, abbreviation OMC), Base station open interferometry when, automatically by Physical Random Access Channel (Physical Random Access Channel, abbreviation PRACH) and detection reference signal (Sounding Reference Signal, abbreviation SRS) it is adjusted to normal upstream time slot.

Further, for better illustrating each step of such scheme, step illustrated below 104 two kinds of implementations.

In a kind of possible implementation, abovementioned steps 104 may specify that as follows：

If the 1041, there is interfered base station, the webmaster in the first networking in all base stations The Interference Detection value that interfered base station sends is received, by the Interference Detection value and the first default threshold Value is compared, and is disturbed serious base station number in determining first networking；And

1042nd, judge to be disturbed the shared ratio in all base station numbers of serious base station number Example, and then judge whether the ratio reaches the second handoff threshold.

After interference check function is opened in the base station of the present embodiment, base station can be according to the detection week for arranging Phase detection receives jamming power (i.e. Interference Detection value), and according to the report cycle for arranging by base station The jamming power that receives of detection reports webmaster.Webmaster side joint receives what all base stations under webmaster reported Interference Detection value, and analyzed and processed.

In alternatively possible implementation, abovementioned steps 104 may specify that as follows：

1041a, webmaster receive be disturbed that serious base station sends be disturbed notification message, institute State after notification message being disturbed for interfered base station acquisition Interference Detection value, the interference is examined Measured value is compared with the first predetermined threshold value, in the Interference Detection value more than or equal to the first default threshold The message sent to the webmaster during value；

1042a, webmaster are according to the quantity for being disturbed notification message for receiving, it is determined that being disturbed tight The base station number of weight, and

1043a, judgement are disturbed the shared ratio in all base station numbers of serious base station number Example, and then judge whether the ratio reaches the second handoff threshold.

In the present embodiment, it is dry that each base station in the first networking may self-determine that whether itself is subject to Whether seriously to disturb, only need to inform webmaster when being disturbed serious in an informed way.By step The mode of 1041a to step 1043a can effectively reduce transmission pressure of the base station to webmaster.Above-mentioned base It is that the first predetermined threshold value that station uses can be sent to base station for webmaster, or advance in base station Side configuration.

It will be appreciated that during this realizes scene, pressure is transmitted in order to avoid increase in base station, as far as possible Consideration does not report Interference Detection value in the case of unnecessary.
