Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for uplink interference positioning.
Background
The uplink interference is the interference of the interference signal in the uplink frequency band of the mobile network, and the mobile base station is interfered by the same adjacent frequency and the like generated by an external radio frequency interference source or unreasonable planning of internal frequency. Uplink interference can cause a reduction in coverage of the base station. A terminal (e.g., a handset) can receive a far terminal signal without uplink interference from a base station. When uplink interference occurs, the terminal signal needs to be stronger than the interference signal, and the base station can communicate with the terminal, so the terminal must be closer to the base station. Uplink interference has a great influence on the processes of access, maintenance, handover, call reestablishment and the like of the terminal, and affects the normal operation of the network and the call quality of the user.
In order to ensure the normal operation of the network and the call quality of the user, the uplink interference needs to be reduced, and then the uplink interference needs to be located.
Currently, there are several methods for positioning uplink interference:
the method comprises the following steps: positioning uplink interference through road frequency sweep test;
the second method comprises the following steps: positioning uplink interference through uplink signal power received by a base station in all frequency domain RB (Resource Block) units using frequency points;
the third method comprises the following steps: uplink interference is located using a spectrometer and a directional antenna.
However, by locating the uplink interference by the above method, only which road is closer to the uplink interference can be determined, and the specific position of the uplink interference cannot be determined. By positioning the uplink interference through the second method, the uplink interference can be positioned in a larger range. By the method for locating uplink interference, the uplink interference is limited by the geographical position, and only the approximate position of the uplink interference can be obtained.
In summary, the problem of low uplink interference positioning accuracy exists in the prior art.

Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
It can be understood that the technical solution of the embodiment of the present invention can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE), a Frequency Division Duplex (FDD) System, a Time Division Duplex (TDD), a WiMAX (Universal Mobile telecommunications System, UMTS), a world wide Microwave Access (UMTS), and the like.
In this embodiment of the present invention, the Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB, NB) in WCDMA, or an evolved Node B (ENB, e-NodeB) in LTE, which is not limited in this embodiment of the present invention. In general, a coverage area of a base station signal can be defined as a cell or a radio cell.
As shown in fig. 1, fig. 1 is a schematic flowchart illustrating an uplink interference positioning method provided in an embodiment of the present invention. It may include:
s101: determining the range of uplink interference according to the average value of the interference noise detected on each uplink PRB counted by the base station;
s102: calculating uplink interference strength corresponding to RSRQ of each sampling point in the MR reported by the UE through SINR;
s103: determining a first sampling point set according to the uplink interference strength and the RSRP;
s104: determining a second sampling point set according to the first sampling point set and the range of the uplink interference;
s105: and positioning the position of the sampling point in the second sampling point set, wherein the distance between the sampling point and the target sampling point in the second sampling point set is smaller than a preset first threshold value, as the position of the uplink interference.
The system measures the total power of the background noise and the adjacent cell interference on each uplink PRB every transmission time interval TTI, and averages the total power on the PRB level to obtain the subcarrier level interference noise power of each PRB, and the value is used as a sample point. And at the end of the counting period, taking the maximum value of each sample point in the period as the maximum value of the PRB-level interference noise detected on each PRB of the system uplink, and calculating the average value of each sample point in the period as the average value L.UL.interference.avg of the PRB-level interference noise detected on each PRB of the system uplink. In practical application, the determination condition of the range in which the uplink interference is located may be: l.ul.interference.avg is greater than-118 dBm (decibel milliwatts/decibel millivolts). The uplink interference may be determined to be within the coverage of one or more cells (i.e., the range in which the uplink interference is located) according to l.ul.interference.avg. Wherein the uplink interference is located in a range which is only an approximate position of the uplink interference.
RSRQ reflects the quality of the reference signal received by the UE from the serving cell and does not directly characterize the interference strength. SINR is a measure of signal quality. The SINR used in the TD-LTE system planning index is the SINR of a cell common reference signal, the SINR generally ranges from-5 dB to 25dB, and the probability that the cell edge SINR > -3dB is required to exceed 95% in the existing TD-LTE system. Because the calculated SINR relates to three aspects of useful signals, interference signals and noise, the noise is relatively fixed and cannot be controlled, the natural noise is-174 dBm/Hz, the noise level of the calculation equipment needs to be added with a noise coefficient, the noise coefficient of a general base station side is 4dB, and the noise coefficient of a terminal side is 7 dB; and combining the downlink reference signal RSRP received by the terminal with the noise to obtain the magnitude of the interference value received by the terminal.
Therefore, the uplink interference strength corresponding to the RSRQ of each sampling point in the MR can be calculated through the SINR.
Specifically, RSRQ ═ N × RSRP/RSSI (1)
Wherein N is the number of PRBs in the current bandwidth; RSRP is reference signal received power; RSSI is an indication of the carrier received signal field strength.
Assuming that the power of a data subcarrier is P and the power of a pilot subcarrier is 2P; for unused PRBs, only two pilot subcarriers have power, so the PRB power is 2 × 2P — 4P; for the used PRB, there are 12 subcarriers on each PRB, where there are 10 data subcarriers with power P and 2 pilot subcarriers with power 2P, so the PRB power is 10 × P +2 × 2P — 14P.
Assume that the current bandwidth PRB number is N, where X PRBs are used and Y PRBs are not used. At this time, the process of the present invention,
RSRQ＝(N*2P)/(X*14P+Y*4P+12*N*NI) (2)
where NI is the average power per subcarrier.
X+Y＝N (3)
NI/2P＝1/SINR (4)
Equation 2 is reduced to using equations 3 and 4:
RSRQ＝1/(2+5X/N+12/SINR) (5)
i.e., RSRQ ═ 10log (2+5X/N +12/SINR) dB (decibel) (6)
SINR＝10log12-10log{1/[power(10，RSRQ/10)]-2-5(X/N)} (7)
Wherein power (10, RSRQ/10) represents 10 RSRQ/10 square.
When empty (i.e., no PRBs are used X-0), RSRQ-10 log (2+12/SINR) dB.
When full load (i.e. N PRBs are used X N), RSRQ-10 log (7+12/SINR) dB.
When the SINR is infinite and there is no load, the RSRQ is-3 dB.
When SINR is-8 dB, full load, RSRQ is-19.5 dB.
As can be seen from equations 6 and 7, when RSRQ is constant, SINR is best at full load and worst at no load. When the RSRQ is smaller than-14.9 dB, the difference value between the no-load SINR and the full-load SINR is smaller than 1, and the no-load SINR is approximately considered to be equal to the actual load SINR during calculation, so that the uplink interference strength corresponding to the RSRQ of each sampling point in the MR is calculated through the SINR, namely the RSRQ in the MR is converted into the SINR to simulate the uplink interference strength.
According to the embodiment of the invention, the first sampling point set is determined according to the uplink interference strength and the RSRP, and the sampling points corresponding to the uplink interference strength smaller than the preset second threshold value and the RSRP larger than the preset third threshold value can be determined as the first sampling point set.
Specifically, the sampled sampling points with the RSRQ values smaller than the preset second threshold have poor receiving quality and the represented SINR values are poor, and the sampled sampling points with the RSRQ values larger than the preset third threshold do not belong to sampling points with extremely poor cell edge coverage.
The embodiment of the present invention determines the second sampling point set according to the first sampling point set and the range of the uplink interference, which may specifically include:
setting each sampling point in the service cell as a sampling point to be processed in sequence;
calculating the difference value of the RSRP of the sampling point to be processed and the sampling point in the adjacent cell of the serving cell;
judging whether the minimum value of the difference value is smaller than a preset fourth threshold value or not;
if the minimum value of the difference value is smaller than a preset fourth threshold value, determining the sampling point to be processed as one sampling point in a third sampling point set;
acquiring a GPS longitude and latitude for each sampling point existing in the first sampling point set but not in the third sampling point set;
screening the GPS longitude and latitude which are positioned in the range of the uplink interference from the acquired GPS longitude and latitude;
and determining the sampling points corresponding to the longitude and the latitude of the GPS obtained by screening as a second sampling point set.
Exemplarily, assuming that the serving cell includes 2 sampling points, which are respectively a sampling point a and a sampling point B, the sampling point a is first set as a sampling point to be processed, an RSRP difference between the sampling point a and a sampling point in a neighboring cell of the serving cell is calculated, and if a minimum value of the calculated difference is smaller than a preset fourth threshold, the sampling point a is determined as one sampling point in a third sampling point set; and then setting the sampling point B as a sampling point to be processed, calculating the RSRP difference value of the sampling point B and the sampling point in the adjacent cell of the serving cell, and if the minimum value of the calculated difference value is smaller than a preset fourth threshold value, determining the sampling point B as one sampling point in a third sampling point set. And obtaining a third sampling point set after all the sampling points in the service cell are calculated. At this time, the overlapping coverage degree of the sampling points in the third sampling point set is high, and the high overlapping coverage degree here refers to interference caused by overlapping coverage of the system downlink signals.
And removing the sampling points in the third sampling point set from the first sampling point set to obtain the sampling points only existing in the first sampling point set but not existing in the third sampling point set.
Further, for each sampling point existing in the first set of sampling points but not in the third set of sampling points, acquiring a GPS longitude and latitude; screening the GPS longitude and latitude which are positioned in the range of the uplink interference from the acquired GPS longitude and latitude; and determining the sampling points corresponding to the longitude and the latitude of the GPS obtained by screening as a second sampling point set.
As can be seen from the above process, in the embodiment of the present invention, the second sampling point set is determined according to the first sampling point set and the range where the uplink interference is located, and the sampling points existing in the range where the uplink interference is located and the first sampling point set at the same time can be directly determined as the second sampling point set.
Specifically, the determining, as the second sampling point set, the sampling points existing in the range in which the uplink interference is located and in the first sampling point set at the same time may specifically include:
acquiring the longitude and the latitude of a GPS (global positioning system) aiming at each sampling point in the first sampling point set;
screening the GPS longitude and latitude which are positioned in the range of the uplink interference from the acquired GPS longitude and latitude;
and determining the sampling points corresponding to the longitude and the latitude of the GPS obtained by screening as a second sampling point set.
Specifically, the GPS longitude and the latitude of the sampling point can be acquired through the Uu interface, the S1-MME and the S1-U signaling association.
Specifically, the S1-U is associated with the S1-MME, and identifies XDR (X Data Recording) of the same Subscriber S1-U and S1-MME by using IMSI (International Mobile Subscriber identity Number), wherein the XDR is a concept evolved from CDR (Call Data Recording). The CDR is a record of network key information during a call in a conventional communication network. XDR is an extension of CDR concept, and generally refers to a key information record of data traffic in a mobile network and a bearer network, that is, a traffic log, and one session forms one XDR record with a user session as a unit;
assigning an ECI (E-UTRAN Cell Identifier ) in the S1-MME XDR of the user in the range of the starting time and the ending time of each S1-U XDR to the S1-U XDR; if the S1-U XDR is associated with more than 2 XDR records with different ECIs of the S1-MME, splitting the S1-U XDR and assigning the starting time and the ECI of the S1-MME to the split S1-U XDR;
and the Uu port MR data is associated with S1-MME, MME records in the time range of MRO (Maintenance Repair Operations) time point and 1 hour before the MRO time point are taken, the consistency of the MME number, the MME group identification and the MME UE S1APID (MME UE Slap identification of UE) is simultaneously met, and the IMSI in the S1-MME XDR closest to the MRO time point in the MME records is assigned to the MR records, wherein the MME is a key control node of a 3GPP protocol LTE access network.
The S1-U is associated with the Uu port MR data, the same user S1-U and the MR record are identified by the IMSI, the MR record is associated with the start time and the end time range of the S1-U XDR, and the position label and the scene label of the piece of S1-U XDR are assigned to the MR record within the range.
Specifically, the MR is associated with the S1-MME and S1-U data by the following two methods.
The method comprises the following steps: the MR is connected in series with the control plane and backfills with one IMSI per minute in the MR with S1APID unchanged. The S1APID in the MME is randomly distributed, has a certain reuse time interval, two MRs in the same cell and within 1 minute of time difference are bound to be the MR of the same user, and the IMSI of the previous MR can be refilled into the next MR.
The second method comprises the following steps: the MR is associated with the control plane and the user plane according to the mode of IMSI + CELL + TIME. After the MR is associated with the S1-MME, the MR data which is not directly matched with the XDR records can be associated with the user plane records from the S1-U XDR according to the key values of IMSI, TIME and CELL identifications, and the records comprise the analyzed user position data (GPS longitude and latitude).
Specifically, since the URI field data of the application APP includes user location data (GPS longitude and latitude), the URI data of the APP can be filtered from the signaling data collected by the S1-U port, and the GPS longitude and latitude can be acquired from the URI data. It can be understood that the APP of the embodiment of the present invention includes, but is not limited to, application programs such as drip car, gold map, Baidu map, WeChat, Xinlang microblog, popular comment, and the like; the embodiment of the present invention does not specifically limit APP.
After the GPS longitude and latitude are obtained, the GPS longitude and latitude located within the range where the uplink interference is located may be screened from the obtained GPS longitude and latitude, and the sampling points corresponding to the screened GPS longitude and latitude are determined as a second sampling point set.
And after the second sampling point set is determined, positioning the position of the sampling point in the second sampling point set, wherein the distance between the sampling point and the target sampling point in the second sampling point set is smaller than a preset first threshold value, as the position of the uplink interference.
Specifically, one sampling point in the second sampling point set is set as a target sampling point in sequence; calculating the distances from other sampling points except the target sampling point in the second sampling point set to the target sampling point; clustering the sampling points with the calculated distance smaller than a preset first threshold value by using a clustering algorithm; and positioning the position of the uplink interference according to the position of the sampling point obtained by clustering, wherein the clustering algorithm can be a K-means algorithm (hard clustering algorithm), and can also be other clustering algorithms.
