Technical Field

[0002] To reduce equipment deployment costs and improve network capacity and performance, different network operators are considering merging indoor distribution systems within the same building to integrate wireless networks.

[0003] Currently, when different network operators merge indoor distribution systems, the main method they use is to retain the cell signal source equipment of one party and remove the cell signal source equipment of the other party. The cell signal source equipment of the retained party opens multiple co-frequency channels. The cells of different indoor distribution systems share multiple co-frequency channels to achieve multiple input multiple output (MIMO) effects.

[0004] However, cells between different network operators often have overlapping coverage. Therefore, merging indoor distribution systems in this way is prone to co-channel interference, resulting in lower network quality of the merged wireless network. Summary of the Invention

[0041] 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.

[0042] 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. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0043] 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.

[0044] In addition, the terms "including" and "having" in the embodiments, claims, and drawings of this application are not exclusive. For example, a process, method, system, product, or device that includes a series of steps or modules is not limited to the listed steps or modules and may also include steps or modules that are not listed.

[0045] In order to facilitate understanding of this application, the relevant elements involved in this application are now described.

[0046] With the deepening development of Internet co-construction and sharing, wireless networks of different network operators are being integrated toward a "single network." For example, two network operators' single-channel indoor distribution systems within the same building can be merged into a shared dual-channel indoor distribution system, improving network capacity and performance while saving the cost of converting their individual indoor distribution systems from single-channel to dual-channel. This solution, combining single-channel indoor distribution systems into a shared dual-channel indoor distribution system, is also referred to as "single-to-dual."

[0047] Currently, when different network operators merge indoor distribution systems, the primary approach is to retain the signal source equipment of one party and remove the signal source equipment of the others. The retained signal source equipment then opens multiple co-frequency channels. Cells (also known as indoor distributed cells) in different indoor distribution systems share these channels to achieve MIMO effects. The signal source equipment in the cells not retained can be removed, saving resources and energy.

[0048] However, during the actual transformation process, due to differences in initial indoor distribution planning, construction, and ongoing maintenance among network operators, the network structure, point distribution, and coverage of the indoor distribution systems of different network operators vary to varying degrees. The indoor distribution system after "single to dual" conversion is prone to severe co-channel interference, resulting in low network quality of the combined wireless network and difficulty achieving the desired transformation results. Especially when the cells of the two indoor distribution systems are staggered and overlapped on different floors, "single to dual" conversion can easily cause severe co-channel interference between the two cells on the same floor, leading to transformation failure or even a decrease in user experience after the transformation.

[0049] For example, Figure 1As shown in the figure, the single-channel indoor distribution systems of operators A and B in the same building have inconsistent planning. Cell a1 under operator A's single-channel indoor distribution system covers floors 1 and 2, while cell a2 covers floors 3 and 4. Cell b1 under operator B's single-channel indoor distribution system covers floors 2 and 3, while cell b2 covers floors 4 and 5. In the common transformation approach, operator A's cells a1 and b1 are merged to form a dual-channel cell, and operator A's cells a2 and b2 are merged to form a dual-channel cell. After the merger, only the signal source equipment of one cell is retained. The signal source equipment of operator A's cell is retained, while that of operator B's cell is removed. In this case, the two merged dual-channel cells use the same frequency f1 as that originally used by operator A's cells a1 and a2. This results in both dual-channel cells being distributed on the third floor of the building, resulting in overlapping coverage and severe co-channel interference. Network quality in the co-channel interference area (i.e., on the third floor) is poor, impacting user experience. If the line distribution in the co-frequency interference area is rectified, it will involve various aspects such as coordination with residents and construction inspection, which is time-consuming and laborious.

[0050] In response to the above problems, an embodiment of the present application provides a frequency determination method. In the present application, according to the cell distribution information of multiple indoor distribution systems in the area to be merged, the cells that meet the preset conditions in each indoor distribution system are merged to obtain multiple merged cells. Then, when there is overlap in coverage among the multiple merged cells, the multiple merged cells can be divided into multiple cell groups, and multiple frequency points corresponding to the multiple cell groups are determined. Since there is no overlap in coverage between the merged cells in the cell group, and the frequency points corresponding to the cell groups with overlapping coverage are different from each other. Therefore, when merging and transforming multiple indoor distribution systems in the area to be merged, the present application can configure different frequency points for the merged cells with overlapping coverage, realize the networking mode of staggered arrangement of the frequencies of each merged cell in the area to be merged, and form a frequency heterogeneous anti-interference indoor distribution network. Therefore, the present application can be used to reasonably determine the frequency points used by the merged cells to avoid the problem of co-frequency interference, thereby improving the network quality of the merged and transformed indoor distribution system.

[0051] The frequency point determination method is applicable to a frequency point determination system. Figure 2 FIG. 1 shows a structure of the frequency determination system 100. Figure 2 As shown, the frequency determination system 100 may include: a frequency determination device 101 and a data acquisition device 102. A communication connection may be established between the frequency determination device 101 and the data acquisition device 102.

[0052] In practical applications, the frequency determination device 101 may be communicatively connected to one or more data acquisition devices 102 .

[0053] For ease of understanding, this application is described by taking a frequency determination device 101 and a data acquisition device 102 as an example.

[0054] Optional, Figure 2 The frequency determination device 101 and the data acquisition device 102 may be functional modules integrated into the same device, or may be two independently configured devices, which is not limited in the present disclosure.

[0055] It's easy to understand that when frequency determination device 101 and data acquisition device 102 are functional modules integrated into the same device, the communication between them is that between internal modules. In this case, the communication process is the same as the communication process between frequency determination device 101 and data acquisition device 102 when they are independently provided.

[0056] For ease of understanding, the present disclosure is mainly described by taking the example that the frequency determination device 101 and the data acquisition device 102 are independently configured.

[0057] Figure 2 The frequency determination device 101 in the embodiment may be configured to be used for providing an application program for frequency determination service. The application program may include operating parameters such as a first direction and a preset threshold value.

[0058] Figure 2 The data acquisition device 102 may have functions such as signal strength test function, bit error rate test function and channel power test function, and is used to provide various test data to the frequency point determination device.

[0059] Optionally, Figure 2 The frequency determination device 101 and the data acquisition device 102 may be terminals, servers, or other types of electronic devices. Figure 2 What is shown in the figure is only an example of the device form of the frequency point determination device 101 and the data acquisition device 102, and does not constitute a limitation thereto.

[0060] 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. The terminal may communicate with one or more core networks via a radio access network (RAN). The terminal may be a mobile terminal, such as a computer with a mobile terminal, or a portable, pocket-sized, handheld, or computer-built-in 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). The embodiments of the present application do not impose any restrictions on this.

[0061] The server may be a single server, or a server cluster consisting of multiple servers. In some implementations, the server cluster may also be a distributed cluster. This embodiment of the present application does not impose any restrictions on this.

[0062] like Figure 3 1 is a schematic diagram of the hardware structure of an electronic device provided in an embodiment of the present application. The electronic device can be a frequency determination device 101 or a data acquisition device 102. The electronic device can include 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.

[0063] The processor 21 is the control center of the electronic device and can be a single processor or a general term for multiple processing elements. For example, the processor 21 can be a CPU or other general-purpose processor. The general-purpose processor can be a microprocessor or any conventional processor.

[0064] As an embodiment, the processor 21 may include one or more CPUs, such as Figure 3 CPU0 and CPU1 are shown in the figure.

[0065] The memory 22 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.

[0066] 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 frequency determination method provided in the following embodiments of the present application can be implemented.

[0067] In another possible implementation, the memory 22 may also be integrated with the processor 21 .

[0068] The communication interface 23 is used to connect the electronic 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.

[0069] 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 3 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.

[0070] It should be pointed out that Figure 3 The structure shown in the figure does not constitute a limitation on the electronic device, except Figure 3 In addition to the components shown, the electronic device may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0071] like Figure 4 The figure is a flow chart of a frequency determination method provided by an embodiment of the present application. The frequency determination method can be applied to Figure 4 The frequency determination device 101 in the frequency determination system 100 is shown. The frequency determination method includes: S401-S403.

[0072] S401. The frequency point determining device merges cells that meet preset conditions in each indoor distribution system according to cell distribution information of multiple indoor distribution systems in the area to be merged, to obtain multiple merged cells.

[0073] The preset condition may include overlapping coverage areas. Further, the preset condition may include the same arrangement order.

[0074] In one possible approach, the area to be merged can be an area covered by the indoor distribution systems of multiple network operators. For example, the area to be merged can be a residential building or an office building, which can be covered by multiple network operators' indoor distribution systems in a vertically distributed manner. The area to be merged can also be a large exhibition hall, which can be covered by multiple network operators' indoor distribution systems in a horizontally distributed manner. Vertical distribution can be achieved by arranging multiple cells vertically. Horizontal distribution can be achieved by arranging multiple cells horizontally.

[0075] In one possible approach, multiple indoor distribution systems can belong to different network operators and can be single-channel indoor distribution systems. Single-channel refers to a single signal path. Multiple cells in the same indoor distribution system generally use the same frequency.

[0076] In one possible approach, personnel can configure the cell distribution information for each indoor distribution system in the data acquisition device based on the design data or relevant test data from the construction of each indoor distribution system. This cell distribution information can include information such as cell coverage and arrangement. Related test information can include signal and power test information for cells in each indoor distribution system. Based on this, the data acquisition device can store multiple distribution information corresponding to multiple areas. A single distribution information item can include cell distribution information for multiple indoor distribution systems.

[0077] Based on this, combined Figure 2The frequency determination device may send a request message to the data acquisition device to obtain the cell distribution information of multiple indoor distribution systems within the area to be merged. For example, the request message may carry the identification information of the area to be merged. In response to the request message, the data acquisition device may read the cell distribution information of the multiple indoor distribution systems within the area to be merged based on the identification information of the area to be merged, and send the cell distribution information of the multiple indoor distribution systems within the area to be merged to the frequency determination device. Accordingly, the frequency determination device obtains the cell distribution information of the multiple indoor distribution systems within the area to be merged.

[0078] In one possible approach, the frequency determination device may determine, in a specific direction, cells with overlapping coverage in each of the indoor distribution systems based on cell distribution information for the multiple indoor distribution systems within the area to be merged. Furthermore, the frequency determination device may determine the coverage of the identified cells with overlapping coverage as the coverage of a merged cell, thereby merging the cells to obtain multiple merged cells.

[0079] One possible example is combining Figure 1 , the preset specific direction is from bottom to top. Operator A's indoor distribution system includes cells a1 and a2. Operator B's indoor distribution system includes cells b1 and b2. The frequency determination device can then determine, from bottom to top, that the cells with overlapping coverage in the two indoor distribution systems are cells a1 and b1, and cells a2 and b2. Furthermore, the frequency determination device can merge cells a1 and b1, and merge cells a2 and b2.

[0080] In one possible approach, the frequency determination device may arrange the cells of multiple indoor distribution systems in a specific direction based on the cell distribution information of the multiple indoor distribution systems within the area to be merged. Furthermore, the frequency determination device may determine the coverage of the cells in the same arrangement order within each indoor distribution system as the coverage of a merged cell, thereby merging the cells to obtain multiple merged cells.

[0081] One possible example is combining Figure 1 , presetting the specific direction to be from bottom to top. The order of cells in operator A's indoor distribution system is cell a1 and cell a2. The order of cells in operator B's indoor distribution system is cell b1 and cell b2. Cell a1 and cell b1 have the same order. Cell a2 and cell b2 have the same order. The frequency determination device can then merge cells a1 and b1, and merge cells a2 and b2.

[0082] S402: When coverage overlaps among multiple merged cells, the frequency determination apparatus divides the multiple merged cells into multiple cell groups.

[0083] There is no coverage overlap between the merged cells within each cell group. That is, for a cell group that includes multiple merged cells, there is no coverage overlap between the merged cells. If a cell group includes only one merged cell, there is no coverage overlap.

[0084] In one possible approach, the frequency determination device can compare the coverage of multiple merged cells. If there is no coverage overlap among the multiple merged cells, this indicates that there will be no co-channel interference between the merged cells after the transformation. In this case, the frequency determination device can configure the same frequency for the multiple merged cells. This same frequency can be the frequency used by a cell in any of the multiple indoor distribution systems.

[0085] If coverage overlaps among multiple merged cells, it may indicate that there may be co-channel interference between the merged cells with overlapping coverage after transformation. In this case, the frequency determination device may divide the merged cells with overlapping coverage into different cell groups to obtain multiple cell groups.

[0086] In one possible approach, considering that merged cells with overlapping coverage generally have an adjacent relationship, the frequency determination device can start from a specific direction in the area to be merged, number multiple merged cells in sequence, and further divide the merged cells with odd numbers into a first cell group, and divide the merged cells with even numbers into a second cell group, thereby dividing the merged cells with overlapping coverage into different cell groups.

[0087] Alternatively, the frequency determination device may arrange multiple merged cells in sequence starting from a specific direction within the area to be merged. Then, the frequency determination device may divide the first merged cell into the third cell group. If there is a coverage overlap between the second merged cell and the first merged cell, the frequency determination device may divide the second merged cell into the fourth cell group. If there is no coverage overlap between the second merged cell and the first merged cell, the frequency determination device may divide the second merged cell into the third cell group. If there is a coverage overlap between the third merged cell and the second merged cell, the frequency determination device may divide the third merged cell into the fourth cell group. If there is no coverage overlap between the third merged cell and the second merged cell, the frequency determination device may divide the third merged cell into the third cell group. And so on, until the grouping of the last merged cell is determined.

[0088] S403. The frequency determination apparatus determines a plurality of frequency points corresponding one-to-one to the plurality of cell groups.

[0089] Among them, the frequency points corresponding to the cell groups with overlapping coverage are different.

[0090] In one possible manner, the multiple frequency points may also be different from each other.

[0091] In one possible manner, the multiple frequency points may be frequency points used by cells in multiple indoor distribution systems, so as to ensure that all cells after merging can have supported cell signal source devices.

[0092] In one possible manner, after dividing the multiple merged cells into multiple cell groups, the frequency determination device configures different frequencies for the multiple cell groups respectively.

[0093] One possible example is combining Figure 1 ,like Figure 5 As shown in FIG, the merged cell consisting of cells a1 and b1 can use frequency f1 originally used by cells a1 and a2 of operator A. The merged cell consisting of cells a2 and b2 can use frequency f2 originally used by cells b1 and b2 of operator B.

[0094] In one embodiment, combining Figure 4 In the above S402, when the frequency determination device divides the multiple merged cells into multiple cell groups when there is overlap in coverage among the multiple merged cells, as shown in FIG. Figure 6 As shown, the embodiment of the present application provides an optional implementation method, including: S501-S502.

[0095] S501: A frequency determination apparatus sequentially numbers a plurality of merged cells starting from a first direction within an area to be merged.

[0096] Alternatively, if the indoor distribution system is deployed in a vertical distribution form within the area to be merged, the first direction may be from bottom to top or from top to bottom. If the indoor distribution system is deployed in a horizontal distribution form within the area to be merged, the first direction may be from left to right or from right to left.

[0097] In one possible manner, the frequency point determination device may number the multiple merged cells in sequence starting from the first direction in the area to be merged. Figure 5 The frequency point determination device may start from bottom to top in the area to be merged, and determine the number of the merged cell composed of cell a1 and cell b1 as 1, and determine the number of the merged cell composed of cell a2 and cell b2 as 2.

[0098] S502. The frequency determination apparatus divides the merged cells with odd numbers into a first cell group, and divides the merged cells with even numbers into a second cell group, to obtain a plurality of cell groups.

[0099] In one possible approach, considering that merged cells with overlapping coverage generally have an adjacent relationship, that is, the merged cells with overlapping coverage are numbered adjacent, in order to divide the merged cells with overlapping coverage into different cell groups, the frequency determination device can divide the merged cells with odd numbers into a first cell group and divide the merged cells with even numbers into a second cell group, thereby obtaining multiple cell groups. Based on this, the frequency determination device can configure different frequencies for different cell groups, so as to configure different frequencies for the merged cells with overlapping coverage, thereby eliminating co-channel interference.

[0100] In a possible example, combined with the example of S501, the frequency determination device may divide the merged cell numbered 1 consisting of cell a1 and cell b1 into the first cell group, and divide the merged cell numbered 2 consisting of cell a2 and cell b2 into the second cell group.

[0101] In one embodiment, combining Figure 4 In the above S403, when the frequency determination device determines multiple frequency points corresponding to multiple cell groups, as shown in FIG. Figure 7 As shown, the embodiment of the present application provides an optional implementation method, including: S601.

[0102] S601. The frequency determination apparatus determines a frequency corresponding to a first cell group as a first frequency, and determines a frequency corresponding to a second cell group as a second frequency.

[0103] The first frequency point may be any one of the multiple currently used frequency points. The second frequency point may be a currently used frequency point other than the first frequency point among the multiple currently used frequency points. The currently used frequency point may be used to indicate the frequency point used by the cell of the indoor distribution system before merging.

[0104] It should be noted that in order to fully utilize frequency domain resources, operators usually assign the same frequency point to multiple cells in the same indoor distribution system and rationally plan the coverage of multiple cells in the same indoor distribution system to avoid co-frequency interference. In addition, different operators generally deploy their indoor distribution systems based on different frequencies. In this case, for each indoor distribution system in the area to be merged, there is generally a corresponding frequency point in use, namely the current frequency point in use. In other words, there are multiple current frequency points that correspond one-to-one to multiple indoor distribution systems in the area to be merged.

[0105] In one possible approach, in order to configure different frequencies for merged cells with overlapping coverage, the frequency determination device can allocate different frequencies to different cell groups, that is, determine the frequency corresponding to the first cell group as the first frequency, and determine the frequency corresponding to the second cell group as the second frequency.

[0106] Based on this, the frequency points used by various operators can be uniformly used and planned in this application. While frequency points can be shared, the frequencies between operators can be interchanged to achieve a distribution method with dual or multiple frequency points arranged at intervals. Therefore, the frequency points of the signal source equipment in each cell of the indoor distribution system can be flexibly configured in this application.

[0107] In one embodiment, Figure 8 As shown, the frequency determination method provided in the embodiment of the present application further includes: S701-S702.

[0108] S701. A frequency determination apparatus obtains a first test value of a signal strength of a merged cell in a central coverage area and a second test value in an edge coverage area.

[0109] The central coverage area may be a circular area with the center point of the coverage area of ​​the merged cell as the center and a preset value as the radius. The preset value can be pre-set in the frequency determination device by the staff as needed. The edge coverage area may be the area within the coverage area of ​​the merged cell excluding the central coverage area.

[0110] Optionally, the central coverage area may also be an area where multiple operators' indoor antennas, feeders and other infrastructure are deployed simultaneously. The edge coverage area may also be an area where some of the multiple operators' indoor antennas, feeders and other infrastructure are deployed.

[0111] For example, combined Figure 5 In the merged cell consisting of cell a1 and cell b1, the second floor is deployed with infrastructure such as single-channel indoor antenna feeders of operators A and B, while the first floor is deployed with infrastructure such as single-channel indoor antenna feeders of operator A, and the third floor is deployed with infrastructure such as single-channel indoor antenna feeders of operator B.

[0112] In this case, within the coverage area of ​​the merged cell, the indoor distribution system on the second floor consists of single-path indoor antennas and feeders from both operators A and B, creating a dual-path distribution system on the same floor. Users of both operators A and B can enjoy a good network experience on the second floor.

[0113] The indoor distribution system on the first floor consists of a single indoor antenna feeder line from operator A on the first floor and a single indoor antenna feeder line from operator B on the second floor, creating a staggered dual-path distribution system. The indoor distribution system on the third floor also consists of a single indoor antenna feeder line from operator A on the second floor and a single indoor antenna feeder line from operator B on the third floor, also creating a staggered dual-path distribution system. Compared to users on the second floor, users on the first floor with operator A's network service may have a poorer network experience, and users on the third floor with operator B's network service may also have a poorer network experience.

[0114] In this case, the second floor can be considered as the central coverage area, and the first and third floors can be determined as edge coverage areas. The difference in signal strength between the central coverage area and the edge coverage area can be used to evaluate the merging effect of the merged cells.

[0115] In one possible approach, in order to improve the network quality of the merged cell and enhance the network usage experience of users in different areas of the merged cell, within the merged cell, staff can deploy data acquisition equipment at different locations in the central coverage area and the edge coverage area to test and obtain multiple signal strength values ​​in the central coverage area and multiple signal strength values ​​in the edge coverage area.

[0116] Based on this, the frequency determination device can obtain multiple signal strength values ​​of the merged cell in the central coverage area and the edge coverage area from the data acquisition device. Furthermore, the frequency determination device can determine the average of the multiple signal strength values ​​in the central coverage area as the first test value for the central coverage area. Furthermore, the frequency determination device can determine the average of the multiple signal strength values ​​in the edge coverage area as the second test value for the edge coverage area.

[0117] S702: The frequency point determination apparatus determines an evaluation result of the merged cell according to the first test value, the second test value and a preset threshold.

[0118] The preset threshold value can be pre-set in the frequency determination device by the staff based on experience. That is, the preset threshold value can be set to different values. For example, the preset threshold value can be 30 decibel milliwatts (dBm) or 100 dBm.

[0119] In one possible approach, the preset threshold may be a first preset threshold. The first preset threshold may be used for comparison with the difference. The difference may be the difference between the first test value and the second test value. Based on this, the frequency point determination device may determine the difference between the first test value and the second test value, and may further compare the determined difference with the first preset threshold to determine the difference in signal strength between the central coverage area and the edge coverage area.

[0120] If the determined difference is less than a first preset threshold, it can indicate that the difference in signal strength between the central coverage area and the edge coverage area is small, indicating that the modification effect is good. If the determined difference is greater than or equal to the first preset threshold, it can indicate that the difference in signal strength between the central coverage area and the edge coverage area is large. In this case, the frequency determination device can output a reminder message to remind staff to make further corrections.

[0121] In one possible manner, the preset threshold may be a second preset threshold. The second preset threshold may be used to directly compare with the test value. Based on this, the frequency determination device may also compare the first test value with the second preset threshold, and compare the second test value with the second preset threshold. If both the first test value and the second test value are greater than or equal to the second preset threshold, it may indicate that the network quality of the merged cell meets the transformation requirements. If the first test value or the second test value is less than the second preset threshold, it may indicate that the network quality of the merged cell does not meet the transformation requirements. In this case, the frequency determination device may output a reminder message to remind the staff to make further rectifications.

[0122] In one embodiment, Figure 9 As shown, a schematic diagram of a frequency determination process provided by an embodiment of the present application is shown. In the case where the frequency determination device is a terminal, the frequency determination device can be configured with functional modules such as an input module and a display module. The input module can be a touch screen, a mouse, a keyboard, etc. The display module can be a liquid crystal display, etc. After the merger and transformation of the indoor distribution system begins, the staff can perform a selection operation on one of the multiple areas through the input module configured by the frequency determination device. In response to the selection operation, the frequency determination device can determine the one area as the area to be merged. The area to be merged may include single-channel indoor distribution systems deployed by multiple operators.

[0123] Next, the frequency determination device can merge the cells of multiple indoor distribution systems in the area to be merged to obtain multiple merged cells. The device can further determine whether there is co-channel interference caused by overlapping coverage among the multiple merged cells, that is, whether there are merged cells with overlapping coverage. If there is no co-channel interference, the frequency determination device can configure the same frequency for the multiple merged cells. This same frequency can be a frequency used by any of the multiple indoor distribution systems.

[0124] If co-channel interference exists, the frequency determination device can perform frequency planning based on the parity of the cell numbers to achieve staggered arrangement of different frequencies within the area to be merged, thereby eliminating co-channel interference. Specifically, the frequency determination device can sequentially number the multiple merged cells starting from a first direction within the area to be merged, determine the frequency corresponding to the merged cells with odd numbers as the first frequency, and determine the frequency corresponding to the merged cells with even numbers as the second frequency.

[0125] Next, the frequency determination device can determine a device retention strategy (also known as a matching selection and retention table) based on the supported frequency information of the cell signal source devices of multiple indoor distribution systems. In this way, this application can support staff in carrying out construction according to the device retention strategy, improve the operational feasibility of the combined transformation, and reduce the transformation cost and simplify the construction.

[0126] Specifically, combined Figure 5 As shown in Table 1 above, in the indoor distribution systems of multiple operators, if only the cell signal source equipment of one indoor distribution system supports the frequency of multiple indoor distribution systems, then the equipment of that party will be retained. For example, in the merged cell with cell number 1 shown in Table 1, the supported frequencies of operator A's cell signal source equipment are 1650 and 1850, and the frequency used by operator A's indoor distribution system is 1850. The supported frequency of operator B's cell signal source equipment is 1650, and the frequency used by operator B's indoor distribution system is 1650. If the frequency determination device determines that the frequency configured for the merged cell is 1650, then in the merged cell with cell number 1, the frequency determination device can determine to retain operator A's cell signal source equipment. Operator A's cell signal source equipment opens a dual-channel shared channel so that the original single-channel indoor distribution systems of both parties are merged into the dual-channel channel of operator A's cell signal source equipment.

[0127] Table 1

[0128]

[0129] If the signal source devices in multiple cells all support the frequencies used by the multi-party indoor distribution system, the devices of the preset operator can be retained. For example, the preset operator can be Operator A. In the merged cell numbered 2 shown in Table 1, the signal source devices in Operator A and Operator B both support frequencies of 1650 and 1850. Therefore, in the merged cell numbered 2, the frequency determination device can determine to retain the signal source devices in Operator A's cell.

[0130] If the signal source equipment of each cell only supports the frequency used by its indoor distribution system, the equipment of each party can be retained in an interval arrangement based on the parity of the numbers.

[0131] The frequency determination device can determine the distribution mode of the merged cells in the area to be merged. The distribution mode of the merged cells can be multi-path distribution in the same area or multi-path distribution in different areas. Figure 5 After the merger of cells a1 and b1, the distribution method on the second floor is dual-path distribution in the same area (also known as dual-path distribution on the same floor), and the distribution method on the first and third floors is dual-path distribution in staggered areas (also known as staggered-floor dual-path distribution). In this way, this application can support the flexible merger of indoor distribution systems in various areas and improve the completeness of the merger and transformation.

[0132] Based on the equipment retention strategy and the distribution pattern of each merged cell, staff can construct and transform multiple indoor distribution systems into multi-channel indoor distribution systems. For merged cells with both same-area multi-channel distribution and staggered multi-channel distribution within their coverage area, signal strength assessment can be considered. Specifically, in such merged cells, staff can deploy data acquisition equipment at different locations in the central coverage area and the edge coverage area to test and obtain multiple signal strength values ​​within the central coverage area and multiple signal strength values ​​within the edge coverage area. Based on this, the frequency determination device can obtain multiple signal strength values ​​in the central coverage area and the edge coverage area of ​​the merged cell from the data acquisition device. The frequency determination device can determine the average of the multiple signal strength values ​​in the central coverage area as a first test value for the central coverage area. Furthermore, the frequency determination device can determine the average of the multiple signal strength values ​​in the edge coverage area as a second test value for the edge coverage area. Furthermore, the frequency determination device determines the signal strength assessment result for the merged cell based on the first test value, the second test value, and a preset threshold.

[0133] In one possible approach, personnel can also use data acquisition equipment to test indicators such as the bit error rate and channel power of each merged cell. Based on this, the frequency determination device can obtain indicators such as the bit error rate and channel power of each merged cell from the data acquisition equipment and further compare them with the corresponding indicator thresholds to determine the co-channel interference test results.

[0134] If the frequency determination device determines that the signal strength evaluation results of each merged cell and the co-channel interference test results meet the requirements, it can be indicated that the indoor distribution system merger and transformation are successful and the process ends. If the frequency determination device has a merged cell whose signal strength evaluation results or co-channel interference test results do not meet the requirements, it can be indicated that there is a merged cell that needs further transformation. In this case, the frequency determination device can output corresponding reminder information to enable the staff to transform the relevant merged cell (for example, replace the cell source equipment, etc.).

[0135] In the present application, according to the cell distribution information of multiple indoor distribution systems in the area to be merged, the cells that meet the preset conditions in each indoor distribution system are merged to obtain multiple merged cells. Then, when there is overlap in coverage among the multiple merged cells, the multiple merged cells can be divided into multiple cell groups, and multiple frequency points corresponding to the multiple cell groups are determined. Since there is no overlap in coverage between the merged cells in the cell group, and the frequency points corresponding to the cell groups with overlapping coverage are different from each other. Therefore, when merging and transforming multiple indoor distribution systems in the area to be merged, the present application can configure different frequency points for the merged cells with overlapping coverage, realize the networking mode of staggered arrangement of the frequencies of each merged cell in the area to be merged, and form a frequency heterogeneous anti-interference indoor distribution network. Therefore, the present application can be used to reasonably determine the frequency points used by the merged cells to avoid the problem of co-frequency interference, thereby improving the network quality of the merged and transformed indoor distribution system.
