Specific embodiment

With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below Example is not intended to limit the scope of the invention for illustrating the present invention.

It include base station, micro- station, pico- station etc. in the first networking in the embodiment of the present invention, wherein base station, micro- station and pico- Station is all connected with network management device (following abbreviation network managements), and network management can be according to the uplink and downlink business datum amount of base station in the first networking Dynamic adjustment TDD ratio of uplink subframe to downlink subframe, and then realize effectively increasing for bandwidth.

First networking of the present embodiment can be indoor networking above-mentioned, can also be the base station, micro- in a certain region of planning It stands and/or the base station networking of the formation such as pico- station.First networking of the present embodiment can be not limited to indoor networking.Preferably to say Bright, the base station outside following the first networkings referred to can be collectively referred to as the outer base station of outdoor base station/networking.

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

Subframe matches 1U3D can are as follows: DSUDDDSUDD；Subframe matches 2U2D can are as follows: DSUUDDSUUD.Following friendships referred to Fork time slot refers to subframe #3 and #8.1U3D subframe #3 and #8 are downlink subframe, and 2U2D subframe #3 and #8 are sub-frame of uplink, 2U2D Frame proportion is lower to open interference check function, detects reception jamming power (i.e. following interference inspection of sub-frame of uplink #2, #3, #7, #8 Measured value), in the case that jamming power on subframe #3 and #8 is significantly raised, it is determined with from the base station of 1U3D subframe proportion Interference.

Fig. 1 shows the flow diagram of the dynamic TDD subframe proportioning regulation method of one embodiment of the invention offer, such as schemes Shown in 1, the dynamic TDD subframe proportioning regulation method of the present embodiment is as described below.

101, network management receives the service rate that each base station reports, and the base station is 1U3D subframe proportion, and belongs to the The base station of one networking.

For example, network management connects all base stations in the first networking, which receives the business speed that each base station reports Rate, can specifically: network management receives the upstream traffic rate and downstream traffic rate that each base station reports；Uplink service speed at this Rate and downstream traffic rate can be the polydispersity index value of base station uplink and downlink (i.e. in a period of time) within a period.For example, Base station periodic sampling evolved base station (evolved Node B, abbreviation eNB) in measurement period eat dishes without rice or wine PDCP layers up and down industries Be engaged in rate, in measurement period add up eat dishes without rice or wine Packet Data Convergence Protocol (Packet Data Convergence Protocol, Abbreviation PDCP) sampled value that is not zero of layer uplink and downlink service rate, accumulated value obtains uplink and downlink business speed divided by accumulative frequency Rate.

The sustainable uplink and downlink service rate counted in the base station in base station is to continue for reporting for uplink and downlink service rate 's.

In a particular application, base station can the uplink and downlink service rate to statistics pre-process, and then can be reported to network management. For example, pretreatment is appreciated that base station by the uplink and downlink service rate of high level statistics with Operation and Maintenance (Operation& Maintenance, abbreviation OM) mode of message or the mode of file summarize, it is reported to network management.

102, the service rate that network management is reported according to all base stations judges the business throughput of all base stations in the first networking Whether reach the first handoff threshold, if so, executing step 103, otherwise, repeats step 101.

Business throughput in the present embodiment can be uplink business data amount and downlink service data amount, the uplink service number Refer to the statistics of the upstream traffic rate of all base stations in the first networking according to amount, downlink service data amount, which refers in the first networking, to be owned The statistics of the downstream traffic rate of base station.

In the present embodiment, network management can add up the upstream traffic rate of base stations all in the first networking, in acquisition Industry business data volume, and the downstream traffic rate of all base stations is added up, obtain downlink service data amount；

And then it can determine whether the uplink business data amount is greater than upstream traffic high load capacity thresholding, and described in judgement Whether downlink service data amount is less than downlink traffic high load capacity thresholding.

It should be noted that the first handoff threshold above-mentioned corresponds to above-mentioned upstream traffic high load capacity thresholding and downlink business Measure high load capacity thresholding.Above-mentioned upstream traffic high load capacity thresholding and downlink traffic high load capacity thresholding can be pre- according to actual needs First set.

If 103, the business throughput of all base stations of first networking reaches the first handoff threshold in step 102, to All base stations of first networking, which send, matches switching for realizing subframe and the first instruction for opening interference check function, with It matches all base stations by the subframe that subframe proportion is switched to 2U2D according to first instruction, and opens interference check function.

In this step, the business throughput of all base stations reaches the first handoff threshold in the first networking, can specifically:

The network management determines that uplink business data amount is greater than upstream traffic high load capacity thresholding, and downlink service data amount is small In downlink traffic high load capacity thresholding.

104, network management judges to be disturbed whether serious base station number reaches the second handoff threshold in all base stations, such as Fruit is to execute step 105, otherwise, executes step 106；

If 105, being disturbed serious base station number in step 104 in all base stations reaches the second handoff threshold (as schemed Shown in 3B), then it is sent to all base stations and realizes the switching of subframe proportion and the second instruction for closing interference check function, so that All base stations match the subframe that subframe proportion is switched to 1U3D according to second instruction, and close interference check function.

If 106, being disturbed serious base station number in step 104 in all base stations is not up to the second handoff threshold (such as Shown in Fig. 3 A), then the notification instruction for controlling UE access is sent to each base station being disturbed, so that interfered base station root The UE access of the base station is controlled according to notification instruction.

For example, admission control is opened after receiving notification instruction in base station, controls new user's access and establishes newly Carrying；It load balancing function can be opened is distributed to the original user of this cell simultaneously and around interfere smaller or glitch-free base station.

107, the service rate that network management is reported according to base station undisturbed in the first networking judges undisturbed all Whether the business throughput of base station reaches third handoff threshold, if so, executing step 108, otherwise, executes 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 uplink and downlink business datum amount.If certain base station Interference Detection value is not higher than the first preset threshold in the first networking, The uplink and downlink business datum amount that then network management counts it adds up the uplink and downlink business datum amount of the base station, if being higher than the first default threshold Value does not count then and the uplink and downlink business datum amount of the base station does not add up the uplink and downlink business datum amount of the base station.

The first preset threshold at this is what the pre-set Interference Detection value reported to base station in network management side was judged Thresholding, the thresholding are used to determine that whether base station to be disturbed in the normal level for not influencing base station performance.

If 108, the business throughput of undisturbed all base stations reaches third handoff threshold in step 107, to All base stations, which are sent, realizes the switching of subframes proportion and the second instruction for closing interference check function so that all base stations according to Second instruction matches the subframe that subframe proportion is switched to 1U3D, and closes interference check function.

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

Citing: when the subframe proportion of base station is 2U2D, the uplink peak speed of each cell is about 20Mbps, and downlink peak speed is big It is generally 80Mbps.Business high load capacity thresholding can be set to 80% or so of peak speed.In the case of indoor networking, if 10 small Area's (0-9) networking and all cells are interference-free, then the uplink service high load capacity thresholding of network is 20Mbps*10*80%= 160Mbps, downlink business high load capacity thresholding are 80Mbps*10*80%=640Mbps；

If wherein 2 cells are disturbed 10 cell networkings, the uplink service high load capacity thresholding of network is 20Mbps* (10-2) * 80%=128Mbps, downlink business high load capacity thresholding are 80Mbps* (10-2) * 80%=512Mbps.Business height is negative Lotus thresholding changes with the variation of interference effect base station number.

If wherein cell 0 and cell 1 are disturbed (interference value is more than that judgement is disturbed thresholding), network management, which only adds up, counts small The service rate of area 2-9, (upper behavior business height is negative for the business high load capacity thresholding that the statistical value and above-mentioned two cell are disturbed Lotus thresholding is 20Mbps* (10-2) * 80%=128Mbps, and downlink business high load capacity thresholding is 80Mbps* (10-2) * 80%= It 512Mbps) is compared and judges.

In the above method, base station is when TDD subframe proportion is switched to 2U2D from 1U3D by dynamic, when detecting the intersection being subject to Gap interfere (i.e. following Interference Detection values), according to interference at crossed slot detected value to whether reside under 2U2D sub-frame configuration into Row judgement is switched under 2U2D subframe proportion, by interference at crossed slot so as to avoid when base station is based only upon upstream traffic Caused service exception.In addition, the indoor base station interference that network management is disturbed by judgement is examined indoors in the case where base station networking Measured value and the indoor base station quantity being disturbed can be realized in the case where guaranteeing rationally to promote uplink service by 1U3D to 2U2D Dynamic TDD subframe match adjustment, solve in the prior art can not in conjunction with indoor base station Interference Detection value and be disturbed Indoor base station quantity realizes the problem of subframe proportion matches adjustment by the dynamic TDD subframe of 1U3D to 2U2D.

It will be appreciated that after base station receives the first instruction in above-mentioned steps 103 interference check function can be opened, i.e., Under 2U2D subframe proportion, base station can open interference check function for base station in the above scheme, that is, support to guide time slot in uplink Every 12 companies on frequency domain are measured on the single symbol and sub-frame of uplink of (Uplink Pilot Time Slot, abbreviation UpPTS) Continue uplink interference power that (12 resource units (Resource Element, abbreviation RE)) is total on subcarrier and operation is reported to tie up Shield center (Operation&Maintenance Center, abbreviation OMC), base station, automatically will be random when opening interference measurement Access physical channel (Physical Random Access Channel, abbreviation PRACH) and detection reference signal (Sounding Reference Signal, abbreviation SRS) it is adjusted to normal upstream time slot.

It further, is each step for better illustrating above scheme, two kinds of realization sides of step 104 illustrated below Formula.

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

If 1041, there are the bases that interfered base station, the network management reception are disturbed in all base stations in the first networking Stand send Interference Detection value, which is compared with the first preset threshold, determine in first networking by The base station number of serious interference；And

1042, judgement is disturbed serious base station number ratio shared in all base station numbers, and then judges the ratio Whether example reaches the second handoff threshold.

After interference check function is opened in the base station of the present embodiment, base station can be detected according to the detection cycle of setting receives interference Power (i.e. Interference Detection value), and network management is reported to according to the jamming power that receives that the report cycle of setting detects base station.Net Pipe flanks the Interference Detection value for receiving that all base stations report under network management, and is analyzed and processed.

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

1041a, network management receive the notification message that is disturbed for being disturbed serious base station transmission, described to be disturbed notification message After obtaining Interference Detection value for interfered base station, which is compared with the first preset threshold, it is dry at this The message sent when disturbing detected value more than or equal to the first preset threshold to the network management；

1042a, network management are disturbed the quantity of notification message based on the received, and determination is disturbed serious base station number, with And

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

In the present embodiment, whether seriously, only each base station in the first networking may self-determine that itself whether be interfered Network management need to be informed in an informed way when being disturbed serious.It can effectively reduce by way of step 1041a to step 1043a Transmission pressure of the base station to network management.What the first preset threshold that above-mentioned base station uses can send for network management to base station, it is also possible to In advance in base station side configuration.

It will be appreciated that pressure is transmitted in order to avoid increasing in base station in the realization scene, consider as far as possible in unnecessary feelings Interference Detection value is not reported under condition.

Base station for Interference Detection value be by eat dishes without rice or wine carry out measurement, mainly completed by physical layer, then by base station OM with The mode of notification message or file is reported to network management, and detection cycle and report cycle can be arranged according to actual needs.

In above-described embodiment, when the base station that 1U3D subframe matches in the first networking since upstream traffic reaches the first switching Thresholding, when the subframe proportion dynamic of base station is adjusted to 2U2D subframe proportion, when intersection is detected in each base station in the first networking The intensity (the Interference Detection value i.e. in the base station of the first networking) of the base station bring interference of outdoor 1U3D subframe proportion in gap, If interference strength is higher than the first preset threshold, it is determined as in the first networking that the base station is disturbed, and Interference Detection value is reported To network management；

The ratio (the second handoff threshold as exemplified above) that network management is disturbed by all base stations in the first networking of analysis, sentences Whether fixed entire networking is disturbed that serious (the indoor station in following Fig. 3 A and Fig. 3 B, Fig. 3 A and Fig. 3 B is in the first networking Base station, outdoor station are the base station outside the first networking), if be disturbed it is not serious if notify interfered base station control UE to connect Enter, and exclude the statistics to the business throughput of above-mentioned interfered base station, by institute in the first networking if being disturbed seriously The subframe for having base station to switch back into 1U3D matches and closes interference check function.
