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 device.

Background

At present, 2G networking is quite mature, and effective coverage can be formed even in complex environments of mountains Gao Gushen and ravines, but with the continuous development of mobile communication technology, 4G networks are taken as new-age wireless communication technologies, have incomparable superiority, and gradually replace 2G networks.

In practical situations, since the 4G macro station is mostly networked in the 1900/2600MHz high frequency band, the coverage area and penetrability of signals are far lower than those of the 2G network networked in the 900/1800MHz frequency band, so that the 4G network is used for replacing the original 2G network in rural areas in mountain areas, and the effective coverage area of the 2/4G signals is required to be measured and calculated.

The traditional distinguishing method is as follows: and calculating whether a 4G base station exists in the 300m range around the target 2G cell according to the longitude and latitude of the station, if so, regarding that the 4G base station has 4G signal coverage, and otherwise, regarding that the 4G base station has no 4G signal coverage. However, in actual production, the judgment method is too simple and coarse, is easy to misjudge, and misdirects accurate optimization and marketing. This is because the determination of the 4G coverage under the 2G cell by the "presence/absence" is not accurate by itself. The method is characterized in 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 capacity of signals is far lower than that of the 2G networking, and under the condition that rural sites in mountain areas are distributed more dispersedly and the inter-site distance is larger, the effective coverage area of the 4G cell is generally smaller than that of the 2G cell. That is, most rural 2G cells can only realize partial coverage of the 4G signals, and whether the 2G cells have common coverage of the 4G signals is quite ambiguous.

That is, the prior art cannot accurately determine the coverage of the 2G cell by the 4G network.

Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

The embodiment of the application provides a network coverage detection method and a graph network coverage detection device. The following will describe in detail.

First, a network coverage detection method is provided in an embodiment of the present application, where the network coverage detection method includes: dividing the effective signal coverage area of the first type cell into at least two first type hot spot coverage areas; dividing the effective signal coverage area of the second type cell into at least two effective coverage areas of the second type; and determining the network coverage condition of the second type cell to the first type cell based on the overlapping degree of at least two first type hot spot coverage areas and the second type effective coverage areas.

Referring to fig. 1, fig. 1 is a flow chart of a network coverage detection method in a first embodiment of the present application. As shown in fig. 1, the network coverage detection method includes:

and S100, carrying out area division on the effective signal coverage areas of the first type cells to obtain at least two first type hot spot coverage areas.

A cell, also called a cell, refers to an area covered by one of base stations 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 through 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 a second generation mobile communication technology (2-Generation wireless telephone technology), mainly comprises two main modes of TDMA (Time division multiple access ) and CDMA (Code Division Multiple Access, narrow band code division multiple access), GSM (Global System For Mobile Communication ) is a mobile communication standard developed based on the TDMA technology, takes a digital voice transmission technology as a core, also supports data transmission and fax, but is only suitable for low-transmission-amount information such as e-mails, software and the like because of slow speed. The 2G cell referred to in this patent application is a GSM cell.

In the embodiment of the present application, the geographic information of the first type cell 11 is obtained, for example, the geographic coordinates of the first type cell 11 are obtained. The effective signal coverage of the first type cell 11 is determined according to the geographic information of the first type cell 11, wherein the effective signal coverage 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, which is determined according to practical situations. The effective signal coverage of the first type cell 11 is area-divided to obtain at least two first type hot spot coverage areas. The effective signal coverage of the first type cell 11 may be divided into areas resulting in 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 statistics are performed in a partitioning manner to obtain at least two first type hot spot coverage areas. And carrying out area division on the effective signal coverage range of the first type cell based on the TA value of the first type cell to obtain at least two first type cell TA partitions. TA (Timing Advance) is the English abbreviation of timing advance, GSM-R system is the time division multiplexing synchronization systemIn general, the synchronization of the system in time is very important, because the mobile station and the cell always have a certain physical distance, when the mobile station and the cell communicate, a delay of number transfer is caused, and if no measures are taken, the delay can cause that a message sent by the mobile station received by the cell on the present time slot overlaps with another message received by the cell on the next time slot, so that the information cannot be decoded correctly. Therefore, in the call progress process, the mobile station carries the delay value measured by the mobile station on the head of the measurement report sent to the cell, and the cell also has to monitor the call arrival time and send an instruction, i.e. timing advance, to the mobile station in the downlink SACCH (Slow Associated Control Channel) message header, and the mobile station adjusts the time advance according to the instruction to achieve the purpose of synchronization. There are three time slots between the mobile station and the transceiver, i.e. the mobile station transmits the signal after receiving the signal in three time slots, so the mobile station transmits the information in consideration of the TA value on the basis of shifting by three time slots. The timing advance takes bit time as basic unit, one time slot in GSM-R system is 0.577ms long, the number of bits transmitted in each time slot is 156.5 bits, so the duration of 1bit is about 3.69us, the timing advance is transmitted by using 6 bits binary numbers, so the TA value is in the range of 0-63, and the speed of wave propagation is about 3 x 10 ⁸ m/s, thus a bit represents a distance value of 3.69us c/2, approximately equal to 550m, i.e. a TA value of approximately equal to 550m for the GSM system.

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

In the embodiment of the present application, the second type cell 11 may be a 4G cell. The 4G is a short for a fourth generation mobile communication technology (The 4th generation mobile communication technology), mainly has two 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 (Multi Input Multi Output, multiple input and output), intelligent antennas, software radio, adaptive transmission and The like, and has The characteristics of higher capacity and transmission rate, better compatibility, stronger anti-interference capability, economical frequency use and The like. The 4G cell in the embodiment of the application refers to a TD-LTE cell.

In the embodiment of the present application, TA measurement statistics of the at least two second type cells are obtained, and statistics are performed in a partitioning manner, so as to obtain at least two second type effective coverage areas. And carrying out area division on the effective signal coverage 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 of the second type cells 12 may be area divided to obtain 2, 3, 4 or more second type cell TA partitions.

In order to guarantee time synchronization on the receiving side (eNodeB side), LTE proposes a mechanism for uplink timing advance (Uplink Timing Advance). 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 in advance by corresponding time.

From the UE side, timing advance is essentially a negative offset (negative offset) between the start time of the received downlink subframe and the time of the transmitted uplink subframe. The eNodeB can control the time at which uplink signals from different UEs arrive at the eNodeB by properly controlling the offset of each UE. For UEs farther from the eNodeB, the uplink data is sent earlier than UEs closer to the eNodeB due to the larger transmission delay.

In the process of initially accessing an LTE network, firstly, an uplink PRACH preamble sequence is sent by UE, the eNodeB returns an initial TA value of 11 bits of the UE in a random access message (RAR) by measuring the preamble sequence of the UE, and meanwhile, the UE side performs corresponding uplink time adjustment according to the initial TA value in the RAR by reporting the initial TA value through a northbound interface; the network side counts the number of reported items according to the TA value size partition, so that TA statistics is TA measurement data of the LTE service cell in a certain time period, and the statistics value can represent the distribution condition and the activity degree of users in different TA regions 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, one OFDM time domain symbol duration is 2048ts=1/15 kHz, that is, ts=1/(15000×2048) = 0.03255us. Therefore, LTE is a ta= (16×ts×c)/2, where the speed of light c is approximately equal to 3×108m/s, i.e. a TA value of the LTE system is approximately equal to 78m.

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

In the embodiment of the present application, the effective coverage situation of the second type cell 12 in the coverage area of the first type cell 11 is determined based on the overlapping degree of at least two first type hot spot coverage areas and the second type effective coverage area. Based on the network service data traffic ratio in the first type hot spot coverage area, the TA measurement statistic ratio in the second type effective coverage area, the overlapping degree of at least two first type hot spot coverage areas and the second type effective coverage area, and the effective coverage condition of the second type cell in the coverage area of the first type cell is determined.
