[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0046] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order.

[0047] Before introducing the cross-zone coverage determination method provided by the present application in detail, a brief introduction to the application scenarios and implementation environment involved in the present application is first given.

[0048] First, a brief introduction to the application scenarios involved in this application is given.

[0049] As described in the background, with the development of mobile communication technology, a large number of base stations have been deployed to expand the coverage of wireless signals. A base station can include one or more cells. However, in mobile communication wireless networks, due to improper cell planning (for example, the corresponding antenna of the cell is too high, or the optimized antenna has changed), the cell may experience over-coverage (i.e., the actual coverage of the cell exceeds the set coverage range), or even cross-coverage (i.e., the coverage range overlaps with the coverage range of the adjacent cell), resulting in network problems (e.g., signaling congestion, signal interference, call interruption, network disconnection, and frequent network switching).

[0050] A common method for determining cross-area coverage is usually to obtain the signal receiving power of the cell and information of sampling points within the cell, and determine the cross-area coverage rate of the cell based on the signal receiving power of the cell and the number of sampling points involved in cross-area coverage.

[0051] However, the general over-coverage determination method only considers cells with over-coverage problems, and it is difficult to accurately determine the over-coverage information of the cells.

[0052] In response to the above problems, an embodiment of the present application provides a method for determining cross-cell coverage. First, the number of sampling points, cell signal parameters, and the distance between the sampling point and the neighboring base station are obtained. Then, based on the number of sampling points, cell signal parameters, and the distance between the sampling point and the neighboring base station, the cross-cell coverage information of the target cell is determined. The cross-cell coverage information includes: coverage information of the target cell covering the neighboring cell and coverage information of the neighboring cell covering the target cell. The sampling points include a first sampling point and a second sampling point. The first sampling point is within the coverage range of the target cell, and the first neighboring cell is used as a sampling point for the serving cell. The second sampling point is within the coverage range of the target cell, and the target cell is used as a sampling point for the serving cell. The cell signal parameters include: signal parameters of the target cell, signal parameters of the first neighboring cell, and signal parameters of the second neighboring cell. The first neighboring cell is a cell covering the first sampling point, and the second neighboring cell is a cell covering the second sampling point. The distance between the sampling point and the neighboring base station includes: the distance between the first sampling point and the base station to which the target cell belongs, and the distance between the second sampling point and the base station to which the second neighboring cell belongs.

[0053] As can be seen from the above, this application determines the cross-cell coverage information of the target cell by the number of sampling points, cell signal parameters, and the distance between the sampling points and the neighboring base stations. When determining cross-cell coverage, not only the coverage information of the target cell covering the neighboring cells is determined, but also the coverage information of the neighboring cells covering the target cell is determined. In this way, not only the impact of the target cell on the neighboring cells is taken into account, but also the impact of the neighboring cells on the target cell is taken into account, and the cross-cell coverage information of the cell can be accurately determined.

[0054] The implementation environment of the above-mentioned cross-area coverage determination method may be the cross-area coverage determination system provided in the embodiment of the present application.

Figure 1 As shown, the cross-area coverage determination system includes: a cross-area coverage determination device 101 and a data storage device 102.

[0056] The cross-coverage determination device 101 and the data storage device 102 are in communication connection with each other.

[0057] In practical applications, the cross-area coverage determination device 101 can be connected to any number of data storage devices 102. Figure 1 An example of a cross-coverage determination device 101 connected to a data storage device 102 is used for description.

[0058] In an embodiment of the present application, the data storage device 102 is used to provide data for cross-zone coverage determination (for example, the number of sampling points, cell signal parameters, and the distance between the sampling point and the neighboring base station, etc.) to the cross-zone coverage determination device 101, so that the cross-zone coverage determination device 101 realizes cross-zone coverage determination based on the data sent by the data storage device 102.

[0059] Optionally, the cross-region coverage determination device 101 can be used in the 4th / 5th-Generation Mobile Communication Technology (4 / 5G) shared network to determine the cross-region coverage information of each cell.

[0060] Optionally, the physical devices of the out-of-area coverage determination device 101 and the data storage device 102 may be servers, terminals, or other types of electronic devices, which is not limited in the embodiment of the present application.

[0061] Optionally, the terminal may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. A wireless terminal may communicate with one or more core networks via a radio access network (RAN). A wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network, such as a mobile phone, tablet computer, laptop computer, netbook, or personal digital assistant (PDA).

[0062] Optionally, the above-mentioned server can be a server in a server cluster (consisting of multiple servers), or a chip in the server, or a system on a chip in the server, or can be implemented through a virtual machine (VM) deployed on a physical machine. This embodiment of the present application does not limit this.

[0063] Optionally, the out-of-area coverage determination device 101 and the data storage device 102 may be two independent devices, or may be integrated into the same device. When the out-of-area coverage determination device 101 and the data storage device 102 are integrated into the same device, the data storage device 102 may be a storage module (e.g., a database, etc.) of the out-of-area coverage determination device 101.

[0064] It is easy to understand that when the out-of-coverage determination device 101 and the data storage device 102 are integrated into the same device, the communication between the out-of-coverage determination device 101 and the data storage device 102 is carried out by means of communication between internal modules of the device. In this case, the communication process between the two is the same as the communication process between the two when the out-of-coverage determination device 101 and the data storage device 102 are independent of each other.

[0065] For ease of understanding, the present application uses an example in which the cross-zone coverage determination device 101 and the data storage device 102 are independent of each other.

[0066] The cross-area coverage determination device in the cross-area coverage determination system includes: Figure 2 The components included. Figure 2 Taking the communication device shown in the figure as an example, the hardware structure of the cross-area coverage determination device is introduced.

[0067] Figure 2FIG2 is a schematic diagram of a hardware structure of a communication device provided in an embodiment of the present application. The communication device includes a processor 21, a memory 22, a communication interface 23, and a bus 24. The processor 21, the memory 22, and the communication interface 23 can be connected via a bus 24.

[0068] Processor 21 is the control center of the communication device and can be a single processor or a collective term for multiple processing elements. For example, processor 21 can be a general-purpose central processing unit (CPU) or other general-purpose processor. The general-purpose processor can be a microprocessor or any conventional processor.

[0069] As an embodiment, the processor 21 may include one or more CPUs, such as Figure 2 CPU0 and CPU1 are shown in the figure.

[0071] In one possible implementation, the memory 22 may exist independently of the processor 21 and may be connected to the processor 21 via a bus 24 for storing instructions or program codes. When the processor 21 calls and executes the instructions or program codes stored in the memory 22, the handover coverage determination method provided in the following embodiments of the present application can be implemented.

[0072] In the embodiment of the present application, for the communication device, the software programs stored in the memory 22 are different, so the functions implemented by the communication device are different. The functions performed by each device will be described in conjunction with the following flowchart.

[0073] In another possible implementation, the memory 22 may also be integrated with the processor 21 .

[0074] The communication interface 23 is used to connect the communication device to other devices via a communication network, which may be Ethernet, wireless access network, wireless local area network (WLAN), etc. The communication interface 23 may include a receiving unit for receiving data and a sending unit for sending data.

[0075] The bus 24 may be an ISA bus, a PCI bus, or an EISA bus. The bus may be divided into an address bus, a data bus, a control bus, and the like. For ease of presentation, Figure 2 Only one thick line is used in the diagram, but this does not mean that there is only one bus or one type of bus.

[0076] It should be pointed out that Figure 2 The structure shown in the figure does not constitute a limitation on the communication device, except Figure 2 In addition to the components shown, the communication device may include more or fewer components than shown, or combine certain components, or arrange the components differently.

Figure 3 As shown, the method for determining cross-area coverage provided in the embodiment of the present application includes:

[0079] The following describes in detail the cross-area coverage determination method provided by the embodiment of the present application with reference to the accompanying drawings.

[0080] The method for determining cross-area coverage provided in the embodiment of the present application is applied to Figure 1 The cross-area coverage determination device 101 in the cross-area coverage determination system shown in FIG. Figure 3 As shown, the method for determining cross-area coverage provided in the embodiment of the present application includes:

[0081] S301: The cross-cell coverage determination device obtains the number of sampling points, cell signal parameters, and distances between the sampling points and neighboring base stations.

[0082] In one achievable manner, the cross-coverage determination device needs to determine the cross-coverage information of the target cell based on the number of sampling points, cell signal parameters, and the distance between the sampling points and the neighboring base stations, so as to determine the cross-coverage impact of the target cell on the neighboring cells and the cross-coverage impact of the neighboring cells on the target cell. Therefore, the cross-coverage determination device needs to obtain the number of sampling points, cell signal parameters, and the distance between the sampling points and the neighboring base stations.

[0083] The sampling points include a first sampling point and a second sampling point.

[0084] The first sampling point is within the coverage of the target cell, and the first neighboring cell is used as the sampling point of the serving cell.

[0085] The second sampling point is within the coverage of the target cell, and the target cell is used as the sampling point of the serving cell.

[0086] The cell signal parameters include: signal parameters of the target cell, signal parameters of the first neighboring cell, and signal parameters of the second neighboring cell.

[0087] The first neighboring cell is a cell covering the first sampling point.

[0088] The second neighboring cell is a cell covering the second sampling point.

[0089] The distances between the sampling points and the neighboring cell base stations include: the distance between the first sampling point and the target cell's home base station and the distance between the second sampling point and the second neighboring cell's home base station.

[0090] Cell signal parameters include: signal transmission frequency and RSRP.

[0091] The sampling point is the measurement report (MR) sampling point.

[0092] Combine Figure 1 ,MR sampling points are in the mobile communication network, where the mobile terminal measures the ,surrounding wireless signal environment and uploads the measurement results and ,measurement locations to the data storage device.

[0093] The measurement results include: the serving cell (also referred to as the primary serving cell) and the neighboring cell (also referred to as the neighboring cell) of the MR sampling point, the signal transmission frequency, and the RSRP.

[0094] Among them, the service cell is a cell that provides wireless communication services to mobile terminals.

[0095] The signal transmission frequency is the signal transmission frequency of the cell. Common signal transmission frequency ranges are 3300-3800MHz, 1805-1880MHz, 1920-1980MHz, and 935-960MHz.

[0096] RSRP can directly reflect the signal strength received by the terminal.

[0097] Specific, combined Figure 1 The cross-area coverage determination device can obtain the number of sampling points, cell signal parameters, and distances between the sampling points and neighboring base stations from the data storage device.

[0098] Specific, combined Figure 1 The out-of-area coverage determination device may obtain the measurement results of the MR sampling points from the data storage device.

[0099] S302: The cross-cell coverage determination device determines cross-cell coverage information of the target cell according to the number of sampling points, cell signal parameters, and distances between the sampling points and neighboring base stations.

[0100] In one practicable manner, the cross-cell coverage determination device can determine the cross-cell coverage information of the target cell based on the number of sampling points, cell signal parameters, and the distance between the sampling points and the neighboring base stations to determine the cross-cell coverage impact of the target cell on the neighboring cells and the cross-cell coverage impact of the neighboring cells on the target cell.

[0101] The cross-cell coverage information includes: coverage information of the target cell covering the neighboring cells and coverage information of the neighboring cells covering the target cell.

[0102] In some embodiments, combined Figure 3 ,like Figure 4 As shown, in S302, the cross-coverage determination device determines the cross-coverage information of the target cell according to the number of sampling points, cell signal parameters, and the distance between the sampling points and the neighboring base station, specifically including:

[0103] S401. The cross-cell coverage determination device determines a first coverage rate according to the number of first sampling points, signal parameters of a target cell, signal parameters of a first neighboring cell, and a distance between the first sampling point and a base station to which the target cell belongs.

[0104] In one feasible manner, the signal coverage range of the target cell crosses into the first neighboring area, thereby affecting the first neighboring area. Therefore, the cross-area coverage determination device may determine the first coverage rate based on the number of first sampling points, the signal parameters of the target cell, the signal parameters of the first neighboring area, and the distance between the first sampling point and the base station to which the target cell belongs, so as to determine the cross-area coverage impact of the target cell on the first neighboring area.

[0105] The first coverage rate (also referred to as cross-cell coverage rate) is used to indicate coverage information of neighboring cells covered by the target cell.

[0106] S402. The cross-cell coverage determination device determines a second coverage rate according to the number of first sampling points, the number of second sampling points, the signal parameters of the target cell, the signal parameters of the second neighboring cell, and the distance between the second sampling point and the base station to which the second neighboring cell belongs.

[0107] In one feasible manner, the signal coverage range of the second neighboring cell crosses into the target neighboring cell, affecting the target neighboring cell. Therefore, the cross-cell coverage determination device can determine the second coverage rate based on the number of first sampling points, the number of second sampling points, the signal parameters of the target cell, the signal parameters of the second neighboring cell, and the distance between the second sampling point and the base station to which the second neighboring cell belongs, so as to determine whether the target cell is affected by the cross-cell coverage of the second neighboring cell.

[0108] The second coverage rate (also referred to as the out-of-area coverage rate) is used to indicate the coverage information of the target cell covered by the neighboring cell.

[0109] In some embodiments, the signal parameters include: signal transmission frequency and RSRP, combined with Figure 4 ,like Figure 5 As shown, in S401, the cross-cell coverage determination device determines a first coverage rate according to the number of first sampling points, the signal parameters of the target cell, the signal parameters of the first neighboring cell, and the distance between the first sampling point and the base station to which the target cell belongs, including:

[0110] S501. The cross-area coverage determination device obtains the number of first-category sampling points, the number of second-category sampling points, the number of third-category sampling points, and the number of fourth-category sampling points in the first sampling points, and determines a first coverage ratio based on the number of the first sampling points, the number of the first-category sampling points, the number of the second-category sampling points, the number of the third-category sampling points, and the number of the fourth-category sampling points.

[0111] In one achievable manner, the signal coverage range of the target cell crosses into the first neighboring cell, affecting the first neighboring cell. If the first neighboring cell and the target cell meet any of the following frequency conditions, the target cell affects the first neighboring cell, where the frequency conditions include: the first neighboring cell and the target cell are co-frequency, the first neighboring cell and the target cell are different frequencies but have the same priority, the first neighboring cell and the target cell are different frequencies and the target cell has a higher priority, and the first neighboring cell and the target cell are different frequencies and the target cell has a lower priority. Therefore, the cross-cell coverage determination device needs to obtain the number of first-category sampling points, the number of second-category sampling points, the number of third-category sampling points, and the number of fourth-category sampling points, and determine the first coverage rate based on the number of first sampling points, the number of first-category sampling points, the number of second-category sampling points, the number of third-category sampling points, and the number of fourth-category sampling points.

[0112] Among them, the first type of sampling point (also called the same-frequency cross-zone coverage sampling point) meets the following conditions: the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is less than or equal to the first preset frequency difference, and the RSRP of the first neighboring cell is greater than the preset power, and the difference between the RSRP of the first neighboring cell and the RSRP of the target cell is less than the preset power difference, and the distance between the first sampling point and the base station to which the target cell belongs is greater than the first preset distance.

[0113] When the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is less than or equal to the first preset frequency difference, the target cell and the first neighboring cell have the same frequency.

[0114] In one practicable manner, the preset power is -105 decibel milliwatts (Decibel relative to one milliwatt, dBm), and the preset power difference is 6 decibels (Decibel, dB).

[0115] The first preset distance is the sum of the target distance and the first distance coefficient (also called a 同频 ) is the product of .

[0116] In one possible implementation, the first distance coefficient is 1.5.

[0117] The second type of sampling point (also called a different-frequency same-priority cross-zone coverage sampling point) meets the following conditions: the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is greater than the first preset frequency difference and less than or equal to the second preset frequency difference, the RSRP of the first neighboring cell is greater than the preset power, the difference between the RSRP of the first neighboring cell and the RSRP of the target cell is less than the preset power difference, and the distance between the first sampling point and the base station to which the target cell belongs is greater than the second preset distance.

[0118] When the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is greater than the first preset frequency difference, the target cell and the first neighboring cell are out of frequency.

[0119] When the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is greater than the first preset frequency difference and less than or equal to the second preset frequency difference, the target cell and the first neighboring cell are out of frequency, and the target cell and the first neighboring cell have the same priority.

[0120] From the above, we can see that the common signal transmission frequency ranges are 3300-3800MHz, 1805-1880MHz, 1920-1980MHz, and 935-960MHz.

[0121] Exemplarily, the signal transmission frequency of the target cell is 3350 MHz, and the signal transmission frequency of the first neighboring cell is 3560 MHz. The signal transmission frequency of the target cell is different from the signal transmission frequency of the first neighboring cell, but they have the same priority.

[0122] In another example, the signal transmission frequency of the target cell is 1830 MHz, and the signal transmission frequency of the first neighboring cell is 1875 MHz. The signal transmission frequency of the target cell is different from the signal transmission frequency of the first neighboring cell, but they have the same priority.

[0123] The second preset distance is the product of the target distance and the second distance coefficient (also called a 异频同优先级 ).

[0124] In one possible implementation, the second distance coefficient is 1.5.

[0125] The third type of sampling point (also called an inter-frequency high-priority inter-zone coverage sampling point) meets the following conditions: the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is greater than the second preset frequency difference, and the signal transmission frequency of the first neighboring cell is lower than the signal transmission frequency of the target cell, and the RSRP of the first neighboring cell is greater than the preset power, and the difference between the RSRP of the first neighboring cell and the RSRP of the target cell is less than the preset power difference, and the distance between the first sampling point and the base station to which the target cell belongs is greater than the third preset distance.

[0126] When the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is greater than the second preset frequency difference, and the signal transmission frequency of the first neighboring cell is less than the signal transmission frequency of the target cell, the target cell and the first neighboring cell are out of frequency, and the priority of the target cell is higher than the priority of the first neighboring cell.

[0127] Exemplarily, the signal transmission frequency of the target cell is 1860 MHz, the signal transmission frequency of the first neighboring cell is 940 MHz, the target cell and the first neighboring cell have different frequencies, and the priority of the target cell is higher than that of the first neighboring cell.

[0128] In another example, the signal transmission frequency of the target cell is 3350 MHz, the signal transmission frequency of the first neighboring cell is 1850 MHz, the target cell and the first neighboring cell have different frequencies, and the priority of the target cell is higher than that of the first neighboring cell.

[0129] The third preset distance is the sum of the target distance and the third distance coefficient (also called a 异频高优先级 ) is the product of .

[0130] In one possible implementation, the third distance coefficient is 2.

[0131] The fourth type of sampling point (also called the inter-frequency low-priority inter-zone coverage sampling point) meets the following conditions: the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is greater than the preset frequency difference, and the signal transmission frequency of the first neighboring cell is greater than the signal transmission frequency of the target cell, and the RSRP of the first neighboring cell is greater than the preset power, and the difference between the RSRP of the first neighboring cell and the RSRP of the target cell is less than the preset power difference, and the distance between the first sampling point and the base station to which the target cell belongs is greater than the fourth preset distance.

[0132] When the absolute value of the difference between the signal transmission frequency of the target cell and the signal transmission frequency of the first neighboring cell is greater than the preset frequency difference, and the signal transmission frequency of the first neighboring cell is greater than the signal transmission frequency of the target cell, the target cell and the first neighboring cell are out of frequency, and the priority of the target cell is lower than the priority of the first neighboring cell.

[0133] Exemplarily, the signal transmission frequency of the target cell is 945 MHz, the signal transmission frequency of the first neighboring cell is 1860 MHz, the target cell and the first neighboring cell have different frequencies, and the priority of the target cell is higher than that of the first neighboring cell.

[0134] In another example, the signal transmission frequency of the target cell is 1845 MHz, the signal transmission frequency of the first neighboring cell is 3370 MHz, the target cell and the first neighboring cell have different frequencies, and the priority of the target cell is higher than that of the first neighboring cell.

[0135] The fourth preset distance is the target distance and the fourth distance coefficient (also called a 异频低优先级 ) is the product of .

[0136] In one possible implementation, the fourth distance coefficient is 2.5.

[0137] In some embodiments, the cross-area coverage determination device determines the first coverage rate according to the number of first sampling points, the number of first-category sampling points, the number of second-category sampling points, the number of third-category sampling points, and the number of fourth-category sampling points, specifically including:

[0138] The cross-area coverage determination device determines a ratio of the sum of the number of first-category sampling points, the number of second-category sampling points, the number of third-category sampling points, and the number of fourth-category sampling points to the number of the first sampling points as a first coverage ratio.

[0139] The first coverage satisfies the following formula:

[0140]

[0141] Among them, θ 越区覆盖率 Used to represent the first coverage, X 同频 Used to indicate the number of first-class sampling points, X 异频同优先级Used to indicate the number of first-class sampling points, X 异频高优先级 Used to indicate the number of first-class sampling points, X 异频低优先级 It is used to indicate the number of first-class sampling points, and X is used to indicate the number of first sampling points.

[0142] In some embodiments, combined Figure 5 ,like Figure 6 As shown, in S402, the cross-area coverage determination device determines the second coverage rate according to the number of first sampling points, the number of second sampling points, the signal parameter of the target cell, the signal parameter of the second neighboring cell, and the distance between the second sampling point and the base station to which the second neighboring cell belongs, including:

[0143] S601. The cross-area coverage determination device obtains the number of fifth-category sampling points, the number of sixth-category sampling points, the number of seventh-category sampling points, and the number of eighth-category sampling points in the second sampling points, and determines a second coverage rate based on the number of first sampling points, the number of second sampling points, the number of fifth-category sampling points, the number of sixth-category sampling points, the number of seventh-category sampling points, and the number of eighth-category sampling points.

[0144] In one achievable manner, the signal coverage of the second neighboring cell crosses into the target cell, affecting the target cell. If the second neighboring cell and the target cell meet any of the following frequency conditions, the second neighboring cell has an impact on the target cell: the frequency conditions include: the target cell and the second neighboring cell are co-frequency, the target cell and the second neighboring cell are different-frequency but have the same priority, the target cell and the second neighboring cell are different-frequency and the second neighboring cell has a higher priority, and the target cell and the second neighboring cell are different-frequency and the second neighboring cell has a lower priority. Therefore, the cross-cell coverage determination device needs to obtain the number of fifth, sixth, seventh, and eighth sampling points in the second sampling points, and determine the second coverage rate based on the number of first, second, fifth, sixth, seventh, and eighth sampling points.

[0145] Among them, the fifth type of sampling point meets the following conditions: the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is less than or equal to the first preset frequency difference, and the RSRP of the target cell is greater than the preset power, and the difference between the RSRP of the target cell and the RSRP of the second neighboring cell is less than the preset power difference, and the distance between the second sampling point and the base station to which the second neighboring cell belongs is greater than the first preset distance condition.

[0146] When the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is less than or equal to the first preset frequency difference, the target cell and the second neighboring cell have the same frequency.

[0147] The sixth type of sampling point meets the following conditions: the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is greater than the first preset frequency difference and less than or equal to the second preset frequency difference, the RSRP of the target cell is greater than the preset power, and the difference between the RSRP of the target cell and the RSRP of the second neighboring cell is less than the preset power difference, and the distance between the second sampling point and the base station to which the second neighboring cell belongs is greater than the second preset distance.

[0148] When the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is greater than the first preset frequency difference, the target cell and the second neighboring cell are out of frequency.

[0149] When the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is greater than the first preset frequency difference and less than or equal to the second preset frequency difference, the second neighboring cell and the target cell are out of frequency, and the second neighboring cell and the target cell have the same priority.

[0150] The seventh type of sampling point meets the following conditions: the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is greater than the second preset frequency difference, and the signal transmission frequency of the target cell is less than the signal transmission frequency of the second neighboring cell, and the RSRP of the target cell is greater than the preset power, and the difference between the RSRP of the target cell and the RSRP of the second neighboring cell is less than the preset power difference, and the distance between the second sampling point and the base station to which the second neighboring cell belongs is greater than the third preset distance.

[0151] When the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is greater than the second preset frequency difference, and the signal transmission frequency of the target cell is less than the signal transmission frequency of the second neighboring cell, the second neighboring cell and the target cell are out of frequency, and the priority of the second neighboring cell is higher than the priority of the target cell.

[0152] The eighth type of sampling point meets the following conditions: the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is greater than the second preset frequency difference, and the signal transmission frequency of the target cell is greater than the signal transmission frequency of the second neighboring cell, and the RSRP of the target cell is greater than the preset power, and the difference between the RSRP of the target cell and the RSRP of the second neighboring cell is less than the preset power difference, and the distance between the second sampling point and the base station to which the second neighboring cell belongs is greater than the fourth preset distance.

[0153] When the absolute value of the difference between the signal transmission frequency of the second neighboring cell and the signal transmission frequency of the target cell is greater than the second preset frequency difference, and the signal transmission frequency of the target cell is greater than the signal transmission frequency of the second neighboring cell, the second neighboring cell and the target cell are out of frequency, and the priority of the second neighboring cell is lower than that of the target cell.

[0154] In some embodiments, the out-of-area coverage determination device determines the second coverage rate based on the number of first sampling points, the number of second sampling points, the number of fifth-category sampling points, the number of sixth-category sampling points, the number of seventh-category sampling points, and the number of eighth-category sampling points, specifically including:

[0155] The cross-zone coverage determination device determines a ratio of the sum of the number of fifth-category sampling points, the number of sixth-category sampling points, the number of seventh-category sampling points, and the number of eighth-category sampling points to the sum of the number of first sampling points and the number of second sampling points as a second coverage ratio.

[0156] The second coverage satisfies the following formula:

[0157]

[0158] Among them, θ 被越区覆盖率 Used to represent the second coverage, Y 同频 Used to indicate the number of sampling points of the fifth category, Y 异频同优先级 Used to indicate the number of the sixth type of sampling points, Y 异频高优先级 Used to indicate the number of sampling points of the seventh category, Y 异频低优先级 It is used to indicate the number of sampling points of the eighth category, X is used to indicate the number of first sampling points, and Y is used to indicate the number of second sampling points.

[0159] Optionally, the cross-area coverage determination device may determine the cross-area coverage rate of any cell to the target cell.

[0160] For example, the cross-cell coverage rate of cell A to the target cell satisfies the following formula:

[0161]

[0162] Among them, θ A对B的越区覆盖率 Used to indicate the cross-area coverage rate of cell A to the target cell, Y A It is used to indicate the number of A cells in the second neighboring area at the second sampling point, and Y is used to indicate the number of second sampling points.

[0163] In some embodiments, combined Figure 6 ,like Figure 7 As shown, the cross-area coverage determination method further includes:

[0164] S701: When a first coverage rate is greater than a first preset coverage rate and / or a second coverage rate is greater than a second preset coverage rate, the inter-cell coverage determination device optimizes operating parameters of a target cell.

[0165] In one achievable embodiment, when a first coverage ratio of a target cell is greater than a first preset coverage ratio, the target cell suffers from severe over-coverage of a first neighboring cell, and the over-coverage determination device needs to optimize operating parameters of the target cell. When a second coverage ratio of the target cell is greater than a second preset coverage ratio, the target cell suffers from severe over-coverage of a second neighboring cell, and the over-coverage determination device needs to optimize operating parameters of the target cell. Therefore, when the first coverage ratio is greater than the first preset coverage ratio and / or the second coverage ratio is greater than the second preset coverage ratio, the over-coverage determination device optimizes the operating parameters of the target cell.

[0166] In one practicable manner, the first preset coverage rate is 50%, and the second preset coverage rate is 30%.

[0167] Optionally, when the first coverage rate is greater than the first preset coverage rate, the out-of-zone coverage determination device marks the target cell as an out-of-zone coverage problem cell (also referred to as a cell causing out-of-zone coverage problems, an out-of-zone coverage interference cell), and optimizes the signal transmission frequency of the target cell (also referred to as radio frequency (RF) optimization), and optimizes the power of the target cell (adjusts the power) to reduce the out-of-zone coverage impact of the target cell on its neighboring cells.

[0171] Optionally, the cross-area coverage determination device can optimize the cells according to priority based on the degree of cross-area coverage impact on the cell and the degree of cross-area coverage impact caused by surrounding cells, accurately solve the problem of cross-area coverage, and reduce the impact of cross-area coverage on user service perception.

[0172] In some embodiments, combined Figure 7 ,like Figure 8 As shown, the cross-area coverage determination method further includes:

[0173] S801. The cross-cell coverage determination device obtains location information of a base station to which a target cell belongs, location information of a base station to which a third neighboring cell belongs, and location information of a base station to which a fourth neighboring cell belongs.

[0174] In one achievable manner, the cross-zone coverage determination device can determine the target distance of the target cell based on the location information of the base station to which the target cell belongs, the location information of the base station to which the third neighboring cell belongs, and the location information of the base station to which the fourth neighboring cell belongs, so that the cross-zone coverage determination device can determine the number of each type of sampling points based on the target distance, cell signal parameters, and the distance between the sampling point and the neighboring cell base station, and determine the first coverage rate and the second coverage rate based on the number of the first sampling points, the number of the second sampling points, and the number of each type of sampling points.

[0175] The distance between the target cell and the third neighboring cell is less than the preset cell distance.

[0176] Optionally, the third neighboring area may be one third neighboring area or multiple third neighboring areas.

[0177] The third neighboring cell's home base station is a non-overlapping base station that is closest to the target cell's home base station.

[0178] Optionally, in different scenarios, the preset cell distance is different.

[0179] For example, in an urban area, the preset cell distance is 800 meters. In a county town, the preset cell distance is 1500 meters. In a township, the preset cell distance is 2000 meters. In a suburban area, the preset cell distance is 5000 meters.

[0180] The distance between the third neighboring cell and the fourth neighboring cell is less than the preset cell distance.

[0181] Optionally, the fourth neighboring area may be one fourth neighboring area or multiple fourth neighboring areas.

[0182] The fourth neighboring cell's home base station is a non-overlapping station (excluding the target cell's home base station) that is closest to the third neighboring cell's home base station.

[0183] For example, Figure 9 A schematic diagram of base station locations is shown.

[0184] Base station 0 is used to indicate the base station to which the target cell belongs, base station 1, base station 2, base station 3, base station 4, base station 5, and base station 6 are used to indicate the base station to which the third neighboring cell belongs, and base station 41, base station 42, base station 43, base station 44, base station 45, and base station 46 are used to indicate the base station to which the fourth neighboring cell belongs.

[0185] S802: The cross-cell coverage determination device determines a first base station distance between the target cell's home base station and the third neighboring cell's home base station according to location information of the target cell's home base station and location information of the third neighboring cell's home base station.

[0186] In one achievable method, the cross-zone coverage determination device can determine the first base station distance between the target cell's base station and the third neighboring cell's base station based on the location information of the target cell's base station and the location information of the third neighboring cell's base station, so as to subsequently determine the target distance of the target cell, so that the cross-zone coverage determination device can determine the number of each type of sampling points based on the target distance, cell signal parameters, and the distance between the sampling point and the neighboring cell base station, and determine the first coverage rate and the second coverage rate based on the number of first sampling points, the number of second sampling points, and the number of each type of sampling points.

[0187] For example, Figure 9 As shown, the distance between base station 0 and base station 3 is the first base station distance. Correspondingly, the distance between base station 0 and base station 1, the distance between base station 0 and base station 2, the distance between base station 0 and base station 4, the distance between base station 0 and base station 5, and the distance between base station 0 and base station 6 can all be considered first base station distances.

[0188] S803: The cross-cell coverage determination device determines a second base station distance between the third neighboring cell's home base station and the fourth neighboring cell's home base station according to the location information of the third neighboring cell's home base station and the location information of the fourth neighboring cell's home base station.

[0189] In one achievable method, the cross-zone coverage determination device can determine the second base station distance between the third neighboring cell's base station and the fourth neighboring cell's base station based on the location information of the third neighboring cell's base station and the location information of the fourth neighboring cell's base station, so as to subsequently determine the target distance of the target cell, so that the cross-zone coverage determination device can determine the number of each type of sampling points based on the target distance, cell signal parameters, and the distance between the sampling point and the neighboring cell base station, and determine the first coverage rate and the second coverage rate based on the number of first sampling points, the number of second sampling points, and the number of each type of sampling points.

[0190] For example, Figure 9 As shown, the distance between base station 4 and base station 41 is the second base station distance. Correspondingly, the distance between base station 4 and base station 42, the distance between base station 4 and base station 43, the distance between base station 4 and base station 44, the distance between base station 4 and base station 45, and the distance between base station 4 and base station 46 can all be considered as the second base station distance.

[0191] S804: The cross-coverage determination device determines an average value of the first base station distance and the second base station distance as a target distance.

[0192] In one achievable manner, the cross-zone coverage determination device may determine the average value of the first base station distance and the second base station distance as the target distance, so as to subsequently determine the target distance of the target cell, so that the cross-zone coverage determination device may determine the number of each type of sampling points based on the target distance, the cell signal parameters, and the distance between the sampling point and the neighboring base station, and determine the first coverage rate and the second coverage rate based on the number of the first sampling points, the number of the second sampling points, and the number of each type of sampling points.

[0193] The handover coverage determination device determines an average value of the first base station distance and the second base station distance as a target distance (which may also be referred to as an average inter-station distance of a target cell).

[0194] Optionally, the cross-area coverage determination device may accurately calculate the target distance of each cell in the target area, and provide a reference value of the target distance for determining cross-area coverage.
