Description

Network coverage detection method and network coverage detection device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a network coverage detection method and a network coverage detection apparatus.

Background

At present, 2G networking is mature, and even in a complex environment with deep mountains and valleys and vertical ravines, effective coverage can be formed, but with the continuous development of mobile communication technology, 4G networks have incomparable superiority as a wireless communication technology of a new era, and it is a necessary trend to gradually replace 2G networks.

In practical situations, since the 4G macro station is mostly networked in the 1900/2600MHz high frequency band, and the coverage and the penetrability of signals are far inferior to those of a 2G network networked in the 900/1800MHz frequency band, the 4G network is used in mountainous rural areas to replace the original 2G network, and the effective coverage of 2/4G signals needs to be measured and calculated.

The conventional discrimination method is: and calculating whether a 4G base station exists in the range of 300m around the target 2G cell through the longitude and latitude of the station, if so, determining that the 4G base station covers the 4G cell, otherwise, determining that the 4G base station covers the 4G cell. However, in actual production, the judgment method is too simple and coarse, is easy to misjudge, and misleads to accurate optimization and marketing. This is because the determination of 4G coverage in a 2G cell by "presence/absence" is not itself accurate. The reason is that the current China Mobile 2G networking adopts 900/1800MHz frequency band, the 4G networking adopts 1900/2600MHz high frequency band networking, the diffraction and penetration capability of signals is far inferior to 2G, and the effective coverage area of the 4G cell is generally smaller than that of the 2G cell under the conditions of scattered rural site distribution and large inter-site distance in mountainous areas. That is to say, partial coverage of 4G signals can only be achieved under most rural 2G cells, and it is very ambiguous whether the 2G cells have 4G signals to cover together.

That is, the coverage of the 4G network to the 2G cell cannot be accurately determined in the prior art.

The embodiment of the application provides a network coverage detection method and a graph network coverage detection device. The following are detailed below.

First, an embodiment of the present application provides a network coverage detection method, where the network coverage detection method includes: carrying out area division on the effective signal coverage area of the first type cell to obtain at least two first type hot spot coverage areas; carrying out area division on the effective signal coverage area of the second type cell to obtain at least two second type effective coverage areas; and determining the network coverage condition of the second type cell to the first type cell based on the overlapping degree of the at least two first type hot spot coverage areas and the second type effective coverage area.

Referring to fig. 1, fig. 1 is a schematic flowchart of a network coverage detection method according to an embodiment of the present application. As shown in fig. 1, the network coverage detection method includes:

s100, carrying out area division on the effective signal coverage area of the first type cell to obtain at least two first type hotspot coverage areas.

A cell, also called a cell, refers to an area covered by one or a part of a base station (sector antenna) in a cellular mobile communication system, in which a mobile station can reliably communicate with the base station via a radio channel.

In the embodiment of the present application, the first type cell 11 may be a 2G cell. 2G is an abbreviation of second Generation Mobile Communication technology (2-Generation wireless telephone technology), and mainly includes two main standards of TDMA (Time Division Multiple Access) and CDMA (Code Division Multiple Access), and GSM (Global System For Mobile Communication) is a Mobile Communication standard developed based on the TDMA technology, and supports data transmission and facsimile with the digital voice transmission technology as a core, but because of its slow speed, it is only suitable For transmitting information such as e-mail and software with low volume. The 2G cell referred to in this patent application is a GSM cell.

In the embodiment of the present application, geographic information of the first-type cell 11 is obtained, for example, geographic coordinates of the first-type cell 11 are obtained. Determining an effective signal coverage range of the first-type cell 11 according to the geographic information of the first-type cell 11, where the effective signal coverage range of the first-type cell 11 is a preset radius range centered on the first-type cell 11, and the preset radius may be 5.5km, and is determined according to an actual situation. The effective signal coverage area of the first type cell 11 is divided into at least two first type hotspot coverage areas. The effective signal coverage area of the first type cell 11 may be divided into 2, 3, 4 or more first type hot spot coverage areas.

In a specific embodiment, data traffic of at least two first-type cells is obtained, and is subjected to partition statistics to obtain at least two first-type hotspot coverage areas. And performing area division on the effective signal coverage area of the first type cell based on the TA value of the first type cell to obtain at least two TA partitions of the first type cell. Ta (timing advance) is an english abbreviation of timing advance, and a GSM-R system is a time division multiplexing synchronization system, so that the synchronization of the system in time is very important, because a certain physical distance always exists between a mobile station and a cell, when the mobile station and the cell communicate, a time delay of number delivery is caused, and if no measures are taken, the time delay causes a message sent by the mobile station on the time slot received by the cell to overlap another message received by the cell in the next time slot, so that the information cannot be decoded correctly. Therefore, in the process of call proceeding, the header of the measurement report sent by the mobile station to the cell carries the delay value measured by the mobile station, the cell must also monitor the time of call arrival and send an instruction, i.e. timing advance, to the mobile station in the message header of the downlink sacch (slow Associated Control channel), and the mobile station adjusts the time to send in advance according to the instruction to achieve the purpose of synchronization. The mobile station has an interval of three time slots between the receiving and the transmitting, that is, the mobile station transmits signals after receiving the signals for three time slots, so the mobile station transmits information after considering the TA value on the basis of shifting three time slots. The timing advance is based on bit time as basic unit, one time slot in GSM-R system is 0.577ms long, the bit number transmitted in each time slot is 156.5bit, so the duration of 1bit is about 3.69us, the transmission of timing advance uses 6 bit binary number, so the range of TA value is 0-63, the speed of radio wave propagation is that the speed of light c is about 3 x 10⁸m/s, so a bit represents a distance value of 3.69us c/2, equal to about 550m, i.e. a TA value of about 550m in the GSM system.

S200, carrying out area division on the effective signal coverage area of the second type cell to obtain at least two second type effective coverage areas.

In the embodiment of the present application, the second type cell 11 may be a 4G cell. The 4G is an abbreviation of The fourth generation mobile communication technology (The4th generation mobile communication technology), mainly including two major standard systems of TD-LTE and FDD-LTE, and compared with The previous generation 3G technology, The 4G adopts key technologies such as OFDM (Orthogonal Frequency division multiplexing), MIMO (multiple Input multiple Output), smart antenna, software radio, and adaptive transmission, and has The characteristics of higher capacity, higher transmission rate, better compatibility, stronger interference resistance, economical Frequency use, and The like. The 4G cell described in the embodiments of the present application refers to a TD-LTE cell.

In the embodiment of the application, the TA measurement statistics of the at least two second-type cells are obtained, and the at least two second-type effective coverage areas are obtained through partition statistics. And performing area division on the effective signal coverage area of the second type cell based on the TA value of the second type cell to obtain at least two TA partitions of the second type cell. The effective signal coverage area of the second type cell 12 may be divided into 2, 3, 4, or more second type cell TA partitions.

In order to ensure time synchronization on the receiving side (eNodeB side), LTE proposes an uplink timing Advance (uplink timing Advance) mechanism. In order to enable the uplink packet of the UE to reach the eNB at the expected time, the radio frequency transmission delay caused by the distance is estimated, and the data packet is sent out at the corresponding time in advance.

From the UE side, timing advance is essentially a negative offset (negative offset) between the start time of receiving the downlink subframe and the time of transmitting the uplink subframe. The eNodeB can control the arrival time of uplink signals from different UEs at the eNodeB by appropriately controlling the offset of each UE. For a UE farther from the eNodeB, due to a larger transmission delay, the UE closer to the eNodeB is required to transmit uplink data earlier.

In the process of initially accessing an LTE network, UE firstly sends an uplink PRACH preamble sequence, eNodeB returns an 11-bit initial TA value to the UE in a random access message (RAR) by measuring the UE preamble sequence, and reports the value through a northbound interface, and the UE side carries out corresponding uplink time adjustment according to the initial TA value in the RAR; the network side counts the reported number according to the TA value, therefore, TA counts the TA measurement data of the LTE service cell in a certain time period, and the statistical value can represent the user distribution condition and the activity degree in different TA areas covered by a certain cell.

The TA value range is 0-1282, one TA length is 16Ts, Ts is the most basic time unit of the LTE system, that is, the minimum sampling interval for digital modulation and fast fourier transform in LTE, and according to the sampling rate of the LTE system, the duration of one OFDM time domain symbol is 2048Ts 1/15kHz, that is, Ts 1/(15000 2048) 0.03255 us. Therefore, LTE-TA (16 × Ts × c)/2, where the speed of light c is equal to 3 × 108m/s, i.e. a TA value of the LTE system is equal to 78 m.

S300, determining the effective coverage condition of the second type cell in the coverage range of the first type cell based on the overlapping degree of the at least two first type hot spot coverage areas and the second type effective coverage area.

In the embodiment of the present application, a network coverage correlation coefficient is determined based on a network service data traffic ratio of a preset number of first-type hotspot coverage areas and an overlap coefficient of a preset number of first-type hotspot coverage areas and a second-type effective coverage area, where the network coverage correlation coefficient is used to measure an effective coverage condition of a second-type cell 12 in a coverage area of a first-type cell 11.

In a specific embodiment, the network coverage correlation coefficient, the data traffic ratio of a preset number of first-type hotspot coverage areas, and the overlap coefficient of a preset number of first-type hotspot coverage areas and second-type effective coverage areas are determined to satisfy the relationship shown in formula (1),

wherein, the value of i in the formula (1) is from 1 to 3, which represents that the network service data traffic accounts for the highest 3 first type hot spot coverage areas; a is_iRepresenting the traffic fraction of the first type hotspot coverage area in the whole first type cell, b_iIs the overlapping coefficient of the first type hot spot coverage area and the second type effective coverage area with preset number, and k represents the network coverage correlation coefficient. The larger the k value is, the closer to 1, the better the signal coverage of the second type cell under the first type cell is; the smaller the k value is, the closer to 0, the less the signal coverage of the second type cell under the first type cell is.

The inventor can know that 27.04% of rural areas in the city have no signal coverage of the second type cells under the first type cells and 20.97% of rural areas in the city have insufficient signal coverage of the second type cells by counting k values of 577 first type cells in the whole rural area in the test point county, as shown in table three and dividing the k values by taking 0.5 as a limit, and the part of cells are the key points needed to pay attention to later-stage planning construction and optimized maintenance work. The cells are the target cells and the priority cells for the construction of the second type cells planned and optimized later.

distribution of k values	0	0-0.5	0.5-0.9	0.9-1
					Cell statistics	156	121	184	116
