Description

Shared new station judgment method based on wireless network signals

Technical Field

The invention relates to the technical field of communication, in particular to a shared new station judgment method based on wireless network signals.

Background

With the rapid development of communication technology, it is required to ensure that the communication infrastructure construction meets the requirements of users on wireless network resources, and it is also required to improve the communication infrastructure sharing rate, increase the resource investment benefit, reduce the resource repeated construction, prevent the resource waste, etc., which has become the working targets of various telecom operators, iron tower companies and communication management departments. Meanwhile, the sharing of the infrastructure brings about reduction of communication cost and communication service cost, which is also a demand of communication users for many years.

Existing large communication iron tower infrastructure service enterprises mainly provide supporting facility services relied on by wireless communication base stations, and supporting facilities mainly refer to iron towers, machine rooms, power utilization and other infrastructure (hereinafter collectively referred to as iron towers). When a new shared base station is generated, the base station needs to be checked, whether the base station is shared or not can only be checked through an account checking platform of a service enterprise at present, but the shared station of an operator generally has the problems that the shared information of an iron tower cannot be updated in time (is omitted or has a large delay) and the like, so that the payment and accounting have potential risks. The current existing method only has monthly manual field check besides checking the account platform, and the method is undoubtedly huge and is not preferable in the aspect of labor cost.

Most of the current research efforts focus on wireless signal quality and user perception of use, with little focus on cost control.

Disclosure of Invention

The present invention is directed to a method for determining a shared new station based on wireless network signals, which overcomes the above-mentioned drawbacks of the prior art.

The purpose of the invention can be realized by the following technical scheme:

a shared new station judging method based on wireless network signals includes obtaining initial data set uploaded by collection terminals installed in each iron tower machine room periodically, obtaining converted data set after base station number conversion is carried out on the initial data set, comparing the converted data set with a reference information base to judge whether suspicious data exist in the converted data set or not, recording corresponding wireless network base station number as effective eNodeBID when suspicious data meet new station judging conditions after the suspicious data are obtained, and recording the effective eNodeBID as a new station if initial data sets uploaded in successive t rounds have the same effective eNodeBID, wherein t is round number threshold value.

Further, the initial data set is a multi-data set, and the content of each data line comprises a mobile country number, a mobile network number, a network carrier frequency point number, a physical cell identifier, a cell number of a wireless network base station, reference signal receiving power and a time advance;

the conversion data set is a multi-data-line data set, and the content of each data line comprises a mobile country number, a mobile network number, a network carrier frequency point number, a physical cell identifier, a cell number of a wireless network base station, reference signal receiving power, a time advance and a wireless network base station number.

Further, in the method, after the conversion data set is generated, it is first determined whether the conversion data set is a first batch of data, if so, a reference information base is established based on the conversion data set, and if not, the conversion data set is compared with the established reference information base.

Further, the determining whether suspicious data exists in the conversion dataset specifically includes the following steps:

101) sequentially extracting data rows in the conversion data set, judging whether the data rows with the same wireless network base station number exist in a reference information base, if so, executing the step 102), and if not, storing the data rows in the conversion data set as suspicious data;

102) judging whether the conditions are met: the TA value of the data row in the converted data set is less than or equal to a TA threshold value, and the TA value of the data row with the same wireless network base station number in the reference information base is greater than the TA threshold value, if so, the data row in the converted data set is stored as suspicious data, and if not, the data row in the reference information base is updated;

103) steps 101) and 102) are repeatedly executed until the conversion data set is compared.

Further, the new station determination condition is specifically:

in the suspicious data, when at least n rows of valid data rows with the same wireless network base station number exist, the valid data rows exist by taking the wireless network base station number as a valid eNodeBID:

TA < ═ TA _ Threshold and RSRP > (RSRP _ Threshold + RSRP _ loss)

Wherein TA is a time advance, TA _ Threshold is a TA Threshold, RSRP is a reference signal received power, RSRP _ Threshold is an RSRP Threshold, RSRP _ loss is an RSRP attenuation value, and n is an active data row Threshold.

Further, when there are 2 or more valid enodebids, one of the most valid data lines is reserved.

Further, when the number of consecutive rounds of obtaining a valid eNodeBID is below t, the reference information base is updated with the suspect data.

Compared with the prior art, the invention has the following beneficial effects:

1) the invention can effectively judge the new shared new station, can reflect the change condition of the exclusive base station in time, and provides a basis for accurately settling the lease cost and the electric charge and reducing the lease cost.

2) The invention can automatically acquire the change of the wireless signal of the base station by a technical means, and can timely discover and early warn the opening of the new station of the friend by combining with the shared new station judgment method, thereby greatly improving the period of confirmation and accounting of the new station, reducing rent and saving cost.

3) The new station judgment process of the invention has simple logic and easy realization, has low requirement on the data processing performance of the server and does not need excessive CPU resources.

4) The invention has stronger reusability, can be reused for GSM, WCDMA and even 5G networks, and only needs to change or adjust corresponding parameters (time delay parameter TA, received signal parameter RSRP) and thresholds. Each operator has different wireless networks, as for the density of base stations, the density of 5G base stations is greater than that of 4G base stations, the density of 3G base stations is greater than that of 2G base stations (related to the spectrum resources of each network), the base stations are built on the multiplexing of the network, and the network with 2G3G, usually 4G, is provided; 2G3G is not necessarily the case with 4G; because the current network construction of China is already in the later 4G period, the LTE network is bound to exist when a new shared station appears, and therefore the invention is explained for the LTE network; the delay parameters and signal strength parameters of other networks are shown in the following table, and corresponding delay parameters and signal strength parameters are only needed for different networks.

Step S102, performing eNodeBID conversion on the CellID in the data set to obtain a converted data set, as shown in table 2. Converting a formula: CellID 256+ Local CellID, 0< ═ Local CellID < 255.

Step S103, comparing the conversion data set with a reference information base, judging whether the conversion data set is the first batch of data, and if so, establishing the reference information base; if not, go to step S104.

Step S104, performing eNodeBID comparison on the conversion data set and the reference information base, judging whether a data row of the conversion data set is already in the reference information base, if so, executing step S105, otherwise, storing the data as suspicious data, and executing step S106.

Step S105, judging whether the TA value of the data row in the conversion data set is smaller than or equal to a TA threshold value, and the TA value of the data row with the same eNodeBID in the reference information base is larger than the TA threshold value, if so, storing the data as suspicious data, executing step S106, and if not, updating corresponding data in the reference information base.

The storage process of the suspicious data can effectively avoid missing new stations. Examples are as follows: suppose that at a certain moment, the iron tower a where the terminal a is located has no new station, and the iron tower B where the terminal B is located has a new station, and the two stations are adjacent or approximately adjacent in position. At the moment, the terminal A collects wireless signal data of the position of the iron tower A at the time T, wherein the data comprises information of a base station where the iron tower B is located; the terminal B collects the information of the base station where the iron tower B is located in T +1 time, the terminal A collects the information firstly, so that the information of the new station of the base station B enters the reference information base, when the terminal B collects the information of the base station where the iron tower B is located in T +1 time, the information of the base station where the iron tower B is located cannot be judged as the new station due to the fact that the information of the base station exists in the reference information base, and the new station is omitted.

Step S106, judging whether the new station judgment condition is met, if so, recording the corresponding wireless network base station number as an effective eNodeBID, if the initial data set uploaded by the successive t rounds has the same effective eNodeBID, recording the effective eNodeBID as a new station, and if t is a round number threshold value, generating a new station early warning, and updating corresponding data to a reference information base, otherwise, directly updating the corresponding data to the reference information base.

TA for LTE networks: timing Advance, generally used for UE uplink transmission, refers to predicting radio frequency transmission delay caused by distance in order to enable a UE uplink packet to reach an eNodeB at a desired time, and sending out a data packet at a corresponding time in Advance. Then, it can be understood that TA is the distance between the UE and the eNodeB.

The distance of the time advance corresponding to 1Ts is equal to: (3 x 10 x 8 x 1/(15000 x 2048))/2 ═ 4.89 m. Meaning distance-1 Ts/2, the propagation speed (speed of light). The distance corresponding to TA is calculated with reference to 1 Ts. TA value unit collected by the terminal: 1TA ═ 16 Ts;

for example: TA is 1, and the distance 16 × 4.89m is 78.12m, which means that the terminal is 78.12m away from the base station, and TA is proportional to the distance.

In general, the distance between dense urban base stations is about 500 meters, and the distance between suburban base stations is about 2000 meters; the terminal equipment is placed in/out of the machine room, the distance between the antenna and the terminal equipment is usually less than 60m, and the TA value of the base station signal collected by the terminal equipment placed in/out of the machine room should be equal to 0 or 1.

The invention adopts the TA value as the main basis, and combines the assistance of the RSRP value of the received signal and the definition of the loss value of the terminal in different scenes, as shown in the table 3, to realize the judgment of the shared new station.

(1) TA is less than the specified Threshold Ta _ Threshold and RSRP is greater than the specified Threshold Rsrp _ Threshold plus the RSRP decay value, and is marked as a valid data line. TA < (r) > TA _ Threshold and RSRP > (RSRP _ Threshold + RSRP _ loss), TA _ Threshold ═ 1 by default, RSRP _ Threshold ═ 90;

(2) if the valid data line count value totalnumcellidttrue of the same eNodeBID is greater than or equal to n lines, the record is denoted as valid eNodeBID. Totalnumcellidttrue > -n, default n-2;

when more than or equal to 2 eNodeBIDs are marked as valid, more valid data lines are reserved.
