Description
Technical Field
The present application relates to the field of communications, and in particular, to a method and an apparatus for determining a coverage capability.
Background
The mobile communication technology has evolved continuously to develop multi-generation communication systems. Currently, operators can operate communication systems of different standards simultaneously. For example, a certain operator may simultaneously operate a Global System for Mobile Communication (GSM) System, a Wideband Code Division Multiple Access (WCDMA) System, and a Long Term Evolution (LTE) System.
On one hand, communication systems of different systems use different technologies, and the coverage capability of the communication systems of different systems is different due to differences in the aspects of base station deployment position, antenna deployment direction and the like. On the other hand, when an operator operates systems of different standards, the cost of network operation and maintenance is high. For the purpose of lower cost, operators currently consider to reduce the frequency of the legacy communication system and quit the network, that is, reduce the bandwidth configuration used by the legacy communication system, and gradually end the operation of the legacy communication system, so that the vacated frequency resources can be used for the communication system of the new system.
Therefore, in order to coordinate systems of different systems and provide seamless network services for users, the coverage capabilities of the systems of various systems need to be accurately analyzed, and an area with a lack of coverage capability of a certain communication system needs to be found, so that reference is provided for the next network construction and network optimization work. Meanwhile, in the process of reducing the frequency and quitting the network of the old-made communication system, the coverage capability of various systems also needs to be analyzed to ensure that the new-made communication system can provide enough coverage capability in the coverage area of the old-made communication system and ensure that the service experience of a user is not reduced.
At present, the way of analyzing various system coverage capabilities mainly depends on extracting Key Performance Indicators (KPIs) in a network management system and combining the KPIs with field tests. For example, when the coordination capability between different systems is analyzed, the success rate of the interoperation between different systems is analyzed, and it is found that the success rate of switching from the fourth generation (4G) communication system to the 3G system is low, corresponding 3G and 4G cells can be called from the network management system, and then a tester goes to the corresponding 3G and 4G cells to perform field test, so as to search a specific switching failure area. Therefore, in the existing coverage capacity analysis method, the field test needs to be carried out by using the testers, so that when the geographic area range corresponding to the cell is large, the workload of the testers is increased, and the test process is complicated.

In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.
The coverage capability determining method provided by the embodiment of the present application may be applied to the communication system shown in fig. 1, where the communication system includes a first system and a second system. The first system may be a fifth generation (5G) mobile communication system, a 4G (e.g., Evolved Packet System (EPS) mobile communication system, a 3G mobile communication system, a 2G mobile communication system, or another actual mobile communication network, and the embodiment of the present application is not limited thereto.
The first system comprises first access network equipment (only one shown in fig. 1 by way of example) and a terminal, and the second system comprises second access network equipment and a terminal. Taking the first system as an example, the access network device may be a base station, for example. It should be noted that, when different communication systems are adopted, names of access network devices may be different, for example, in a 3G system, a base station is named nodeb (nb), in a 4G system, a base station is named eNB, in a 5G system, a base station is named gNB, and a name of an access network device does not form a limitation on the access network device itself.
The terminal may be a User Equipment (UE), such as: a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) telephone, a smart phone, a Personal Digital Assistant (PDA), a laptop computer, a handheld communication device, a handheld computing device, and/or other devices for communicating over the communication system shown in fig. 1.
It can be understood that, a plurality of access network devices may be deployed in the first system and the second system, and a plurality of terminals may be provided with network services in the first system and the second system, respectively.
It should be noted that the first system and the second system each have respective coverage areas and respective coverage capabilities, so as to provide the corresponding network services to the users in the respective coverage areas.
The network device can communicate with a first access network device, a second access network device and a terminal in a first system and a second system respectively through a network. In the embodiment of the present application, the network device is configured to import certain data and load a preset algorithm program to execute a process of calculating the coverage capability of the first system and the second system. When the first access network device and the second access network device are both base stations as shown in fig. 1, the imported data includes, but is not limited to, location information of each cell covered by each base station in the first system, antenna azimuth information of each cell covered by each base station in the first system, location information of each cell covered by each base station in the second system, and antenna azimuth information of each cell covered by each base station in the second system.
An embodiment of the present application provides a coverage capability determining method, as shown in fig. 2, the method may include S201-S202:
it should be noted that, in the embodiment of the present application, the comparison of the coverage capabilities of different systems is mainly performed with respect to the coverage capabilities of macro base stations in different systems, that is, the comparison of the outdoor environment coverage capabilities (considering part of the indoor environments without deploying the indoor subsystem). As the indoor environment is a closed environment, it is obvious that the coverage of the communication system with the indoor base station is generally stronger than that of the communication system without the indoor base station. Meanwhile, the two communication systems of the indoor base stations are deployed, so that the difference in the coverage capability of the indoor environment is not too large, and therefore, the comparison of the coverage capability of the indoor base stations is relatively simple to implement, and is not discussed too much herein, and the comparison of the coverage capability of the indoor base stations can be referred to in the prior art, which is described in a unified manner herein and is not described in detail below.
In this embodiment of the application, for example, the network device shown in fig. 1 executes the following steps S201 and S202, so as to implement the calculation of the coverage capability of multiple communication systems, which is described herein in a unified manner and is not described again below.
S201, respectively obtaining a distance between each first cell of the first system and each second cell of the second system, and respectively obtaining an antenna azimuth angle included angle between each first cell of the first system and each second cell of the second system.
Optionally, the distance between the first cell and the second cell may be a distance between a base station to which the first cell belongs and a base station to which the second cell belongs, or a distance between a center point of the first cell and a center point of the second cell. Of course, the distance between the first cell and the second cell may also be calculated in other ways, which is not limited in this embodiment of the application.
The included angle of the azimuth angle of the antenna between the first cell and the second cell may be an included angle between the ray directions of the azimuth angle of the antenna arranged on the base station to which the first cell belongs and the antenna arranged on the base station to which the second cell belongs. The ray direction of the antenna azimuth angle can be approximately regarded as the direction of the cell antenna transmitting signals, and for example, the ray direction of the antenna azimuth angle can be the direction corresponding to the main lobe center in the horizontal direction (i.e. the radiation direction of the main lobe center).
S202, respectively determining the coverage capability of the second system and the coverage capability of the first system according to the distance between each first cell of the first system and each second cell of the second system and the antenna azimuth angle included angle between each first cell of the first system and each second cell of the second system.
In the embodiment of the present application, the following two cases may exist in determining the coverage capability of the second system and the coverage capability of the first system:
in case 1, a distance between a second cell with the same coverage capability and a corresponding first cell is smaller than a first threshold, and an antenna azimuth angle between the second cell with the same coverage capability and the corresponding first cell is an acute angle (i.e., the range of the antenna azimuth angle is 0 degree to 90 degrees), and the antenna azimuth angle between the second cell with the same coverage capability and the corresponding first cell is within a first preset range. The first threshold and the first preset range may be set according to a specific application scenario, and a description is given here in a unified manner, which is not described in detail below.
The following describes a manner of determining whether a second cell with the same coverage capability exists in a certain first cell in the first system by taking a cell a in the first system and a cell b in the second system as an example, referring to fig. 3, assuming that the first threshold is 20 meters and the first preset range is 0 degrees to 15 degrees, querying whether at least one second cell satisfying the following two conditions exists in the second system for the cell a in the first system:
condition 1: the distance to cell a is less than or equal to 20 meters.
Condition 2: and an included angle beta of an antenna azimuth angle between the antenna and the cell a is greater than or equal to 0 degree and less than or equal to 15 degrees.
As shown in fig. 3, after traversing each second cell in the second system, finding that the cell b satisfies the above condition 1 and condition 2 shows that the coverage areas of the two cells overlap more, and the wireless propagation environment is more complex, it can be considered that the cell a of the first system and the cell b of the second system have the same coverage capability. As a specific example, if the distance between two cells is 0 and the included angle between the azimuth angles of the antennas of the cells is 0, it is a situation of the co-site construction in the conventional sense, that is, both the first system and the second system are deployed at the same site.
It should be noted that the present invention does not limit the initial side and the final side of the included angle β between the azimuth angles of the two cell antennas, that is, the included angle between the initial side and the final side is β, no matter the radial direction of the azimuth angle of the antenna of the cell a is rotated counterclockwise or clockwise by β, which is equal to the radial direction of the azimuth angle of the cell b.
In case 2, the distance between the second cell with the same coverage capability and the corresponding first cell is smaller than the second threshold and larger than the third threshold, and the antenna azimuth angle included angle between the second cell with the same coverage capability and the corresponding first cell is an obtuse angle (i.e., the range of the antenna azimuth angle included angle is 90 degrees to 180 degrees), and the antenna azimuth angle included angle between the second cell with the same coverage capability and the corresponding first cell is within a second preset range. The second threshold, the third threshold, and the second preset range may be set according to a specific application scenario, and a description is given here in a unified manner, which is not described in detail below.
In the following, taking cell a in the first system and cell b in the second system as an example to illustrate the manner of determining whether a second cell with the same coverage capability exists in a certain first cell in the first system in the second case, referring to fig. 4, optionally, the second threshold is MAX (R1, R2) + MIN (R1, R2)/2, where MAX symbol represents taking the maximum value, MIN symbol represents taking the minimum value, R1 is the equivalent coverage radius of the first system, and R2 is the equivalent coverage radius of the second system. The calculation methods of R1 and R2 are similar, and the average single station coverage area of the first system and the second system in a certain area can be respectively adopted, and then the average equivalent coverage radius is calculated, in this case, the cells in the certain area all adopt the same equivalent coverage radius value. The coverage radius of each cell may also be calculated according to a link budget method, where each cell has its own equivalent coverage radius, that is, the equivalent coverage radius values of different cells may be different. The respective equivalent coverage radius of each cell may also be calculated according to a Time Advance (TA) actually generated by each cell in each system, and at this Time, each cell has its own equivalent coverage radius. The embodiment of the application does not limit the specific calculation method of the equivalent coverage radius. Assuming that the average single station coverage area of the first system and the second system in a certain area is adopted, the average equivalent coverage radius R1 and R2 of each cell in the two systems are respectively converted, and the method is as follows:
the average single station coverage area of the first system is equal to the coverage area of the first system area/the number of base stations of the first system area
The average single station coverage area of the second system is the coverage area of the second system area/the number of base stations of the second system area
Optionally, the third threshold is MAX (R1, R2).
The second preset range is 165 degrees to 180 degrees, so as to query, for the cell a of the first system, whether at least one second cell meeting the following two conditions exists in the second system:
condition 3: the distance between the cell a and the cell a is less than or equal to the distance of the second threshold value and greater than or equal to the distance of the third threshold value.
Condition 4: and an included angle beta of an antenna azimuth angle between the antenna and the cell a is larger than or equal to 165 degrees and smaller than or equal to 180 degrees.
As shown in fig. 4, after traversing each second cell in the second system, it is found that the distance between cell b and cell a is 500 meters, and assuming that the distance is less than or equal to MAX (R1, R2) + MIN (R1, R2)/2 and greater than or equal to MAX (R1, R2), it means that cell b satisfies condition 3, and it is also found that cell b satisfies condition 4, so cell b in the second system has the same coverage capability as cell a in the first system, that is, the coverage areas of these two cells overlap relatively much.
It should be noted that, for the cell a of the first system, in order to improve the working efficiency of the network, one of the two combinations of the condition 1 and the condition 2 or the condition 3 and the condition 4 is selected and executed, that is, it may be determined whether there is a second cell satisfying the condition 1 and the condition 2, or it may be determined whether there is a second cell satisfying the condition 3 and the condition 4, specifically, which two conditions are determined first, and the embodiment of the present application is not limited. And, when at least one second cell satisfies condition 1, condition 2, or satisfies condition 3, condition 4, the second cell is considered to have the same coverage capability as cell a. Or, in order to improve the calculation accuracy, two combination conditions may also be determined, and only when it is determined that there is no combination satisfying any one of the two combination conditions, it is determined that there is no second cell having the same coverage capability as the cell a.
In the above description, the method for determining whether there is a second cell having the same coverage capability as the first cell is described with the cell a of the first system and the cell b of the second system, and according to the same method, it can be determined whether each first cell of the first system has a corresponding second cell, so as to obtain the coverage capability comparison results of the first system and the second system.
Similarly, it can be determined whether each second cell of the second system has a corresponding first cell.
Specifically, the following 4 cases exist when the coverage capabilities of the first system and the second system are judged:
case 1: the second system has better coverage than the first system.
Specifically, when each of the first cells in the first preset number of first cells of the first system has a corresponding second cell with the same coverage capability in the second system, and each of the second cells in the second preset number of second cells of the second system does not have a corresponding first cell with the same coverage capability in the first system, the coverage capability of the second system is greater than that of the first system. For example, in the example of the present application, the second system has the same coverage capability in a coverage area of a first cell over 90% (the ratio can be set by itself, and logically the value of the ratio should be close to or equal to 100%) in all the first cells of the first system, and meanwhile, in a coverage area of a second cell of 10% (the ratio can be set by itself, and logically the value of the ratio should be close to or equal to 0%) in the second system, the first system does not have the same coverage capability, which means that the first system can cover the same area, and the second system can also cover the same area, but the second system can cover an area which the first system can not necessarily cover, i.e. the coverage area of the second system is wider, so the coverage capability of the second system is better than that of the first system.
Case 2: the second system has a weaker coverage capability than the first system.
For the same reason as above, when each of the first cells of the first predetermined number of first cells of the first system does not have a corresponding second cell with the same coverage capability in the second system, and each of the second cells of the second predetermined number of second cells of the second system has a corresponding first cell with the same coverage capability in the first system, the coverage capability of the second system is weaker than that of the first system.
Case 3: the coverage capability of the first system is the same as the second system.
As a possible implementation manner, when each of a first preset number of first cells of a first system has a corresponding second cell with the same coverage capability in a second system, and each of a second preset number of second cells of the second system also has a corresponding first cell with the same coverage capability in the first system, the coverage capability of the second system may be regarded as the same as that of the first system.
Case 4: the coverage capability of the first system and the coverage capability of the second system each have advantages.
As a possible implementation manner, when each of the first cells in the first preset number of first cells of the first system does not have a corresponding second cell with the same coverage capability in the second system, and each of the second cells in the second preset number of second cells of the second system does not have a corresponding first cell with the same coverage capability in the first system, the coverage capability of the second system has advantages and disadvantages with the first system.
It will be appreciated that various network operations may be purposefully deployed after determining the coverage capabilities of the first and second systems, respectively. Illustratively, if the first system and the second system are required to have the same coverage capability, then supplementary construction and network optimization adjustment work is carried out on an area with insufficient coverage of a certain system. For another example, if the first system needs to perform frequency reduction network quitting and the second system needs to provide supplementary coverage for the first system after frequency reduction network quitting, then the frequency reduction network quitting operation of the first system can be selected to be performed first in an area with good coverage of the second system.
The coverage capability determining method provided in the embodiment of the present application obtains a distance between each first cell of the first system and each second cell of the second system and an antenna azimuth angle included angle between each cell of the first system and each second cell of the second system, respectively, and determines a coverage capability comparison condition between the first system and the second system according to the obtained data. The field test link is reduced, and the workload of personnel is reduced.
Further, by adopting the technical solution of the embodiment of the present application, not only the difference between the coverage capabilities of the first system and the second system can be determined, but also it can be known in which areas, for example, the second system does not reach the same coverage capability as the first system, and actually refers to geographical areas with coverage of the first cell but not the second cell, or in which areas, the first system does not reach the same coverage capability as the second system. Such as a first system with better coverage and a second system with poorer coverage in a geographic area. Therefore, according to the coverage capability difference in a specific geographic area, optimization work is carried out on the first system and the second system so as to improve the service quality.
Of course, the technical solution of the embodiment of the present application may also be applied to a multi-frequency point deployment scenario, where a first system may be deployed on multiple frequency points, and if any one of the frequency points in the first system has a coverage capability in a geographic area, the first system may not distinguish the frequency points when the first system has the coverage capability in the geographic area, and directly execute the above procedure to determine whether a second cell having the same coverage capability exists in each first cell in the first system.
Or, according to the needs of system performance, for example, if only a certain frequency point can achieve better performance in a certain geographic area under the condition that continuous coverage is achieved at the certain geographic area, it may be specified that only if the frequency point has coverage capability in the certain geographic area, the system is considered to have overall coverage capability in the geographic area. In this case, the frequency points need to be distinguished, and the above-mentioned process is executed for one or more cells under each frequency point in the first system, that is, for a certain frequency point in the first system, it is determined which cells under the frequency point are covered in which frequency points of the second system do not have the same coverage capability, and which frequency points of the second system are covered in which cell under the frequency point of the first system are covered in which frequency points of the second system have the same coverage capability. Similarly, the above calculation procedure is performed for all cells under each frequency point of the second system. For example, the first system deploys 3 frequency points, where frequency point 1, frequency point 2, and frequency point 3 all correspond to 3 cells, frequency point 1 corresponds to cell 1, cell 2, and cell 3, frequency point 2 corresponds to cell 4, cell 5, and cell 6, frequency point 3 corresponds to cell 7, cell 8, and cell 9, according to the above calculation procedures, it can be calculated whether cells 1 to 9 have corresponding second cells with the same coverage capability, and subsequently, it can be determined whether each frequency point has continuous coverage capability in a certain geographic area by using the calculation result.
Of course, in order to simplify the calculation, the operator may set a dominant coverage frequency point, also called a background frequency point, among the multiple frequency points of the first system, where the background frequency point is often the strongest in coverage capability, so that when two systems compare the coverage capabilities, only the coverage capabilities of the background frequency points may be compared.
The network device (also referred to as coverage capability determining apparatus herein) may be divided into functional modules or functional units according to the above method examples, for example, each functional module or functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module may be implemented in a form of hardware, or may be implemented in a form of a software functional module or a functional unit. The division of the modules or units in the embodiment of the present application is schematic, and is only a logic function division, and there may be another division manner in actual implementation.
Fig. 5 shows a schematic diagram of a possible structure of the coverage capability determining apparatus in the above embodiment. The coverage capability determining apparatus 500 includes an obtaining module 501, a determining module 502, and a judging module 503.
