Description

A kind of method and apparatus of alien frequencies Interference Detection

Technical field

The present invention relates to communication technical field, more particularly, to a kind of method and apparatus of alien frequencies Interference Detection.

Background technology

For TD-LTE (Time Division-Long Time Evolution, time-division Long Term Evolution) system, typically The cell signal of 20MHz bandwidth can be with as shown in figure 1, cell signal strength be concentrated in bandwidth of cell, but outside bandwidth of cell There is also spurious signal, the intensity of spurious signal for both sides gradually to reduce, presentation is roll-offed feature.Because radio-frequency filter is believed neighbour The suppression in road is limited, and the spurious signal of the transmission signal of side channel will also fall into the bandwidth of the radio-frequency filter of this channel It is interior, therefore, when the signal of the side channel received is sufficiently large, the part PRB (Physical of this channel will be caused Resource Block, Physical Resource Block) bottom makes an uproar lifting, and will also it cause this channel to block when serious.Further, for TD-LTE system, clock stringent synchronization is required between the cell of each base station equipment.If frame head between base station equipment or when Gap proportioning is inconsistent, or step loss condition occurs in clock, then occurs the downstream signal of a stylobate station equipment to another stylobate station The ascending time slot of equipment is disturbed, and interference at crossed slot can cause the obvious lifting of the system noise of disturbed base station equipment, And network performance may be caused to have a strong impact on, it is disturbed serious base station equipment or even work can not be normally carried out.Such as Fig. 2 institutes Show, be the inconsistent schematic diagram of time slot proportion, as shown in figure 3, inconsistent for the clock step-out or frame header deviation of base station equipment Schematic diagram.

For example, the frequency spectrum assigned in China Mobile's D frequency ranges is 2575~2635 common 60M bandwidth, divide in CHINAUNICOM's D frequency ranges The frequency spectrum arrived is 2555~2575 common 20M bandwidth, and the frequency spectrum assigned in China Telecom's D frequency ranges is 2635~2655 common 20M bandwidth. When CHINAUNICOM establishes TD-LTE 20M cells using 2555~2575, China Mobile establishes TD-LTE using 2575~2595 20M cells, if the base station equipment of CHINAUNICOM and the base station equipment of China Mobile are closer to the distance, and the frame between base station equipment Either time slot proportion is inconsistent or step loss condition occurs in clock for head, will appear from interference at crossed slot.When China Telecom uses 2635~2655 establish TD-LTE 20M cells, and China Mobile establishes TD-LTE 20M cells using 2615~2635, if in The base station equipment of state's telecommunications and the base station equipment of China Mobile are closer to the distance, and frame head or time slot proportion between base station equipment It is inconsistent, or there is step loss condition in clock, will appear from interference at crossed slot.

In the prior art, according in this cell 20MHz bandwidth ascending time slot carry out Interference Detection, to it is each up when Gap (such as subframe 2, subframe 3, the UpPTS (uplink pilot time slot) of special subframe 1 and GP (protection interval time slot) character position) connects The interfering signal power received, measured according to PRB granularity.Wherein, for 100 PRB in cell 20MHz bandwidth Interfering signal power, if there is interfering signal power exceed pre-determined threshold PRB, then it is assumed that the PRB exist interference.If 100 PRB interfering signal power is relatively flat, does not possess obvious feature of roll-offing, then it is assumed that is that same frequency in this channel is done Disturb.If 100 PRB interfering signal power possesses obvious feature of roll-offing in certain side of bandwidth of cell, then it is assumed that is adjacent The alien frequencies interference of channel.Wherein, the feature of roll-offing of alien frequencies interference is as shown in Figure 4.

In above-mentioned implementation, by the ascending time slot Interference Detection in this bandwidth of cell, it is merely able to learn interference Source frequency is the alien frequencies interference source of the co-channel interference source or side channel in this channel, but can not learn the tool of alien frequencies interference source Body frequency point information, the actual interference signal power that this antenna in cell mouth receives can not be also learnt, therefore, above-mentioned implementation exists It is difficult to apply in the interference investigation of real network O＆M.

Embodiment one

For problems of the prior art, the embodiment of the present invention one provides a kind of method of alien frequencies Interference Detection, should Method is the method based on alien frequencies interference at crossed slot detection location interference source, the application scenarios using Fig. 5 as the embodiment of the present invention Schematic diagram, this method can apply to include in the network that server, OMC and base station equipment are adjudicated in supervision.Wherein, supervision judgement Server connects the OMC of multiple operators, can inquire about and operate the state of the base station equipment of each operator.Base station equipment Role can be divided into disturbed base station equipment and interference source base station equipment.Disturbed base station equipment carries out alien frequencies Interference Detection, if It was found that interference source frequency is the frequency of other operators, then submits to supervision judgement server and handled.

Under above-mentioned application scenarios, as shown in fig. 6, the method for the alien frequencies Interference Detection comprises the following steps：

Step 601, disturbed base station equipment carries out alien frequencies interference to each frequency of each operator (such as China Mobile) Detection, to obtain each PRB of the interference signal on each frequency general power.

In the embodiment of the present invention, disturbed base station equipment is each to each operator (such as China Mobile, CHINAUNICOM) Frequency carries out the process of alien frequencies Interference Detection, is specifically including but not limited to following manner：

Mode one, disturbed base station equipment are opened different after receiving the alien frequencies interference check function from OMC and starting order Frequency interference check function, and alien frequencies Interference Detection is carried out to each frequency of each operator.Wherein, alien frequencies interference check function Starting order is sent after OMC detects generation alien frequencies interference.

In the embodiment of the present invention, OMC receives the interference alarm information from disturbed base station equipment；If interference alarm disappears The information that alien frequencies interference occurs for disturbed base station equipment is carried in breath, then OMC detects that alien frequencies interference occurs for disturbed base station equipment, and Alien frequencies interference check function is sent to disturbed base station equipment and starts order, and the alien frequencies interference check function starts order and is used to indicate Disturbed base station equipment opens alien frequencies interference check function, and alien frequencies Interference Detection is carried out to each frequency of each operator.Or OMC receives the interference alarm information from disturbed base station equipment；If carry disturbed base station equipment pair in the interference alarm information The interfering signal power information that each ascending time slot of cell receives, then OMC each ascending time slot of cell is received Interfering signal power information measures according to PRB granularity；If OMC detects disturbed base station equipment hair based on measurement result Raw alien frequencies disturbs, then OMC sends the startup order of alien frequencies interference check function, the alien frequencies interference check function to disturbed base station equipment Start order to be used to indicate that disturbed base station equipment opens alien frequencies interference check function, and each frequency of each operator is carried out Alien frequencies Interference Detection.

Specifically, disturbed base station equipment carries out Interference Detection in this channel, if it find that interference be present, then sent to OMC Alarm information is disturbed, OMC receives the interference alarm information from disturbed base station equipment.(1) if carried in interference alarm information The information of alien frequencies interference occurs for disturbed base station equipment, then OMC detects that alien frequencies interference occurs for disturbed base station equipment, to disturbed base station Equipment sends alien frequencies interference check function and starts order or notify operation maintenance personnel to open alien frequencies in disturbed base station equipment manually Interference check function.If carrying the information that co-channel interference occurs for disturbed base station equipment in interference alarm information, OMC is according to existing There is flow processing, the processing will not be repeated here.Or (2) carry disturbed base station equipment to small if disturbed in alarm information The interfering signal power information that each ascending time slot in area receives, then what OMC received to each ascending time slot of cell does Signal power information is disturbed to measure according to PRB granularity.For example, the interfering signal power received to each ascending time slot, Measured according to PRB granularity.For the interfering signal power of 100 PRB in cell 20MHz bandwidth, if there is Interfering signal power exceeds the PRB of pre-determined threshold, then it is assumed that the PRB has interference.If 100 PRB interfering signal power It is relatively flat, and the interfering signal power detected not up to blocks thresholding, does not possess obvious feature of roll-offing, then it is assumed that be this Co-channel interference in channel.If 100 PRB interfering signal power possesses obvious spy of roll-offing in certain side of bandwidth of cell Sign, or the interfering signal power detected reach obstruction thresholding, then it is assumed that are the alien frequencies interference of side channel.Further, such as Fruit OMC detects that alien frequencies interference occurs for disturbed base station equipment based on measurement result, then OMC sends alien frequencies to disturbed base station equipment and done Disturb detection function and start order or notice operation maintenance personnel the unlatching alien frequencies interference check function in disturbed base station equipment manually.Its In, ascending time slot specifically includes：Subframe 2, subframe 3, UpPTS the and GP character positions of special subframe 1, time domain granularity can be sons Frame level is other, can also be refined as symbol rank.

Specifically, disturbed base station equipment carries out Interference Detection in this channel, and it is normal in the cell of this disturbed base station equipment In running, interfering signal power information that disturbed base station equipment receives to each ascending time slot of cell, according to PRB Granularity measure.For example, for the interfering signal power of 100 PRB in cell 20MHz bandwidth, if there is interference Signal power exceeds the PRB of pre-determined threshold, then it is assumed that the PRB has interference.If 100 PRB interfering signal power compares It is flat, and the interfering signal power detected not up to blocks thresholding, does not possess obvious feature of roll-offing, then it is assumed that be this channel Interior co-channel interference.If 100 PRB interfering signal power possesses obvious feature of roll-offing in certain side of bandwidth of cell, Or the interfering signal power detected reaches obstruction thresholding, then it is assumed that is the alien frequencies interference of side channel.Further, if by Disturb base station equipment and detected based on measurement result and alien frequencies interference occurs, then directly open alien frequencies interference check function, and to each Each frequency of operator carries out alien frequencies Interference Detection.Wherein, ascending time slot specifically includes：Subframe 2, subframe 3, special subframe 1 UpPTS and GP character positions, time domain granularity can be subframe rank, can also be refined as symbol rank.

Mode three, when disturbed base station equipment opens (i.e. always on) alien frequencies interference check function in real time, then disturbed base Station equipment periodically carries out alien frequencies Interference Detection to each frequency of each operator.

In the embodiment of the present invention, disturbed base station equipment carries out alien frequencies Interference Detection to each frequency of each operator, with The process of each PRB of the interference signal on each frequency general power is obtained, is specifically included：

Mode one, base station equipment are led to using RRU (Radio Remote Unit, Remote Radio Unit) general service radio frequency Road, and based on the mode of filter compensation coefficient progress alien frequencies Interference Detection.

In the embodiment of the present invention, disturbed base station equipment carries out attenuation coefficient outside RRU filter band according to every PRB real Calibration is surveyed, and obtains the pad value K (i) outside wave filter band on each frequency, i numbers for PRB；Wherein, pad value K (i)= P0-R (i), P0 are each PRB power of the interference signal received, and R (i) is the interference signal work(on each PRB detected Rate；Disturbed base station equipment establishes detection cell using idle base-band resource and business radio-frequency channel, will detect the frequency of cell The frequency being revised as outside the radio frequency bandwidth that disturbed base station equipment is supported, and obtain detection cell detecting on each frequency Interfering signal power Q (i)；Disturbed base station equipment calculates power P (i) of actually eating dishes without rice or wine=Q (i)+K (i) of interference signal, to obtain Each PRB of the interference signal on each frequency general power.

For the RRU of disturbed base station equipment general service radio-frequency channel, its radio frequency bandwidth supported will be by its band logical The limitation of radio-frequency filter, for example, the filter bandwidht for China Mobile D frequency ranges RRU is 2575~2635 common 60M bandwidth, CHINAUNICOM D frequency ranges RRU filter bandwidht is 2555~2575 common 20M bandwidth, China Telecom D frequency ranges RRU wave filter band A width of 2635~2655 common 20M bandwidth.In RRU filter bandwidhts, signal that RRU is received is zero-decrement to pass through radio-frequency filter It is sent to inside RRU and is handled.Outside RRU filter bandwidhts, after signal that RRU is received will carry out certain decay, lead to Cross radio-frequency filter and be sent to inside RRU and handled.Obvious spy of roll-offing is presented in bandwidth both sides for RRU radio-frequency filter Sign, frequency is smaller closer to decaying, bigger further away from decaying.As shown in fig. 7, to carry out the schematic diagram of alien frequencies Interference Detection, frequency Rate is smaller closer to decaying, bigger further away from decaying.

Based on above-mentioned filter characteristic, surveyed after RRU receives signal, disturbed base station equipment is by RRU filtering Device out-of band rejection coefficient carries out actual measurement calibration according to every PRB, obtains the pad value K on each PRB frequencies outside wave filter band (i), i numbers for PRB.Wherein, method of testing can use standard signal source outputting standard interference signal, by the interference signal Export to RRU.Each PRB power of the interference signal received at RRU antenna openings is P0.Disturbed base station equipment normal work, Alien frequencies Interference Detection is opened, it is R (i) to detect the interfering signal power on each PRB, then K (i)=P0-R (i).
