Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a call control method for neighboring cell communication, a computer-readable storage medium, a computer device, and a call control device for neighboring cell communication. Background Technology

[0002] In related technologies, handover in area management is a crucial technology for ensuring interconnectivity between user equipment in neighboring areas under standalone networking mode. In areas such as tunnels and subway platforms, signal calls are only made within the local area and are not sent to adjacent areas, requiring third-party equipment intervention for calls between neighboring areas and the local area. Therefore, it is necessary to enable interconnectivity with neighboring areas but not with non-adjacent areas, allowing users in neighboring areas to call users in the local area, thereby improving user communication efficiency. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in the aforementioned technologies. To this end, one objective of this invention is to propose a call control method for neighboring cell communication. This method automatically controls whether to merge with neighboring cell signals for communication through a threshold, effectively preventing interference signals from neighboring cells below the threshold from merging into the main cell and causing noise interference. This ensures that the main cell signal is always valid and does not communicate with devices in non-adjacent areas, meeting the needs of specific scenarios and thereby improving user communication efficiency.

[0004] A second objective of this invention is to provide a computer-readable storage medium.

[0005] The third objective of this invention is to provide a computer device.

[0006] The fourth objective of this invention is to provide a call control device for inter-cell communication.

[0007] To achieve the above objectives, a first aspect of the present invention proposes a call control method for neighboring cell interconnection, applied to a wireless communication system. The wireless communication system includes multiple optical master units. Each optical master unit is connected to the optical master unit of its left neighboring cell via a first optical port, to the optical master unit of its right neighboring cell via a fourth optical port, to multiple optical remote units in its own cell via a third optical port, and to multiple optical remote units in neighboring cells via a second optical port. The call control method for neighboring cell interconnection includes the following steps: acquiring a call signal from the current cell, a call signal from the left neighboring cell, and a call signal from the right neighboring cell; and processing the call signal from the current cell... The call signals from the left and right neighboring cells are converted to obtain the corresponding optical power values ​​of the local area, the left neighboring cell, and the right neighboring cell. These values ​​are then compared with preset threshold values ​​to obtain the corresponding call results. Thus, by automatically controlling whether to incorporate neighboring cell signals for communication, the system effectively prevents interference signals from neighboring cells below the threshold from incorporating into the main area and causing noise interference. This ensures that the main area signal remains valid and does not communicate with devices in non-adjacent areas, meeting specific scenario requirements and improving user communication efficiency.

[0008] In addition, the call control method for neighboring cell interconnection proposed in the above embodiments of the present invention may also have the following additional technical features:

[0010] Optionally, the optical power value of the local area, the optical power value of the left neighboring area, and the optical power value of the right neighboring area are compared with preset threshold values ​​to obtain corresponding call results. This includes: comparing the optical power value of the local area with the preset threshold values ​​to determine the comparison result; if the comparison result is that the optical power value of the local area is higher than the preset threshold value, then only the call signal of the local area is received; if the comparison result is that the optical power value of the local area is lower than the preset threshold value, then the optical power values ​​of the left neighboring area and the right neighboring area are further compared with the preset threshold values ​​to obtain corresponding call results.

[0011] Optionally, if the comparison result shows that the optical power value of the local area is lower than the preset threshold, then the optical power values ​​of the left neighboring area and the right neighboring area are further compared with the preset thresholds to obtain the corresponding call result, including: comparing the optical power values ​​of the left neighboring area and the right neighboring area with the preset thresholds to determine the comparison result; if the comparison result shows that both the optical power values ​​of the left neighboring area and the right neighboring area are lower than the preset thresholds, then only the call signal of the local area is received; if the comparison result shows that ... If the optical power value of the neighboring cell is higher than the preset threshold and the optical power value of the right neighboring cell is lower than the preset threshold, then the call signal of this cell and the call signal of the left neighboring cell are received; if the comparison result is that the optical power value of the right neighboring cell is higher than the preset threshold and the optical power value of the left neighboring cell is lower than the preset threshold, then the call signal of this cell and the call signal of the right neighboring cell are received; if the comparison result is that the optical power values ​​of both the left and right neighboring cells are higher than the preset threshold, then the call signal of this cell and the call signal of the right neighboring cell are received.

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the invention to those skilled in the art.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] It should be noted that the call control method for neighboring cells is applied to wireless communication systems, such as... Figure 3 As shown, the wireless communication system includes multiple optical master units (OMUs). Each OMU is connected to the optical master unit of the left neighboring cell via the first optical port OP1, to the optical master unit of the right neighboring cell via the fourth optical port OP4, to multiple optical remote units (ORUs) in the local cell via the third optical port OP3, and to multiple optical remote units (ORUs) in neighboring cells via the second optical port OP2. Each OMU independently selects a neighboring cell handover strategy, determines whether to merge with a neighboring cell call signal, selects based on communication quality according to the OMUs in the local cell and the left and right neighboring cells, and selects to switch left and right neighboring cell signals based on the judgment result after comparing threshold values. Assuming that there are 16 channels in the local cell and the left and right thresholds, each channel independently performs threshold judgment and handover, and there is no connection between channels.

[0028] refer to Figure 1 As shown, the call control method for neighboring cell interconnection in this embodiment of the invention includes the following steps:

[0029] S101, acquire the local call signal, the call signal of the left neighboring cell, and the call signal of the right neighboring cell.

[0030] As an example, the local area call signal includes the signal received by the optical master unit of the local area and the signals received by all optical remote units connected to the third optical port of the optical master unit of the local area; the left neighbor area call signal includes the signal sent by the optical master unit of the left neighbor area to the optical master unit of the local area through the first optical port of the optical master unit of the local area; the right neighbor area signal includes the signal sent by the right neighbor area to the optical master unit of the local area through the fourth optical port of the optical master unit of the local area.

[0031] Specifically, such as Figure 3 As shown, Area1 sends a signal to Area2 through OP1 of OMU2, which represents a left neighboring cell call signal; Area3 sends a signal to Area2 through OP4 of OMU2, which represents a right neighboring cell call signal; the signal received by OMU2 is superimposed on the signals received by all ORUs cascaded to OP3 of OMU2, which together constitute the local area call signal.

[0032] S102, convert the local area call signal, the left neighbor area call signal and the right neighbor area call signal to obtain the corresponding local area optical power value, the left neighbor area optical power value and the right neighbor area optical power value.

[0033] It should be noted that the OMU can convert local call signals, left neighbor call signals, and right neighbor call signals into optical power values ​​in dBFS through its built-in signal detection module and power conversion algorithm.

[0034] S103, compare the optical power value of this area, the optical power value of the left neighboring area, and the optical power value of the right neighboring area with preset threshold values ​​respectively to obtain the corresponding call results.

[0035] In other words, the signals being compared include the call signal received in this area, the call signal from the left neighboring cell, and the call signal from the right neighboring cell. After converting the signals being compared into optical power signals in dBFS, they are compared with the threshold values ​​respectively, and then the neighboring cell signals are switched based on the comparison values ​​obtained.

[0036] It should be noted that, in order to prevent the ping-pong effect caused by the signal jittering around the threshold value, the design is such that when the signal is greater than the threshold value, it will only be considered to be less than the threshold value when the signal is less than the threshold value by 3dBfs.

[0037] Specifically, such as Figure 4 As shown, the OMU2 converts the left neighbor cell call signal, right neighbor cell call signal, and local cell call signal into optical power values ​​in dBFS and compares them with the threshold values ​​configured in the OMU2. If the value exceeds the threshold, the value is set to 1; if the value does not exceed the threshold, the value is set to 0.

[0038] As one embodiment, the optical power value of the local area, the optical power value of the left neighboring area, and the optical power value of the right neighboring area are compared with preset threshold values ​​to obtain the corresponding call results. This includes: comparing the optical power value of the local area with the preset threshold values ​​to determine the comparison result; if the comparison result is that the optical power value of the local area is higher than the preset threshold value, then only the call signal of the local area is received; if the comparison result is that the optical power value of the local area is lower than the preset threshold value, then the optical power values ​​of the left neighboring area and the right neighboring area are further compared with the preset threshold values ​​to obtain the corresponding call results.

[0039] As an example, if the comparison result shows that the optical power value of the local area is lower than a preset threshold, the optical power values ​​of the left and right neighboring areas are further compared with preset thresholds to obtain the corresponding call results. This includes: comparing the optical power values ​​of the left and right neighboring areas with preset thresholds to determine the comparison result; if the comparison result shows that both the optical power values ​​of the left and right neighboring areas are lower than the preset thresholds, only the call signal of the local area is received; if the comparison result shows that the optical power value of the left neighboring area is higher than the preset threshold and the optical power value of the right neighboring area is lower than the preset threshold, both the call signal of the local area and the call signal of the left neighboring area are received; if the comparison result shows that the optical power value of the right neighboring area is higher than the preset threshold and the optical power value of the left neighboring area is lower than the preset threshold, both the call signal of the local area and the call signal of the right neighboring area are received; if the comparison result shows that both the optical power values ​​of the left and right neighboring areas are higher than the preset thresholds, both the call signal of the local area and the call signal of the right neighboring area are received.

[0040] In other words, a threshold value is configured in the OMU. When the local call signal is higher than the threshold value, the signals of the left and right neighboring cells are not connected, and the local cell can only receive its own call signal. When the local call signal is lower than the threshold value, and the signal of either the left or right neighboring cell is higher than the threshold value, the neighboring cell signal higher than the threshold value is merged into the local cell signal. At this time, the local cell can receive its own call signal and the neighboring cell call signal higher than the threshold value. When the local call signal is lower than the threshold value, and the signals of both the left and right neighboring cells are higher than the threshold value, the signal of the right neighboring cell is merged into the local cell signal. At this time, the local cell can receive its own call signal and the right neighboring cell call signal. When the local call signal is lower than the threshold value, and the signals of both the left and right neighboring cells are lower than the threshold value, the signals of both the left and right neighboring cells are not connected, and the local cell can only receive its own call signal.

[0041] It should be noted that when the signal in this area is below the threshold, the system will first determine whether the signal in the neighboring area meets the condition. If the signals in both the left and right neighboring areas are above the threshold, the right neighboring area signal will be forcibly selected for forwarding in this area instead of the left neighboring area. This is a preset priority rule designed to resolve the conflict when the signals in the left and right neighboring areas are valid at the same time, ensuring that the system can stably select one neighboring area for communication when multiple neighboring area signals coexist, and avoiding signal confusion or inability to determine priority.

[0042] As a specific example, such as Figure 2 As shown, OMU2 integrates the judgment values ​​after comparing the left neighbor cell signal, right neighbor cell signal, and local cell signal with the threshold. If the local cell signal exceeds the threshold, it is not merged with the left or right neighbor cell signals. If the local cell signal is below the threshold, it checks whether either the left or right neighbor cell exceeds the threshold and merges the neighbor cell signal exceeding the threshold into the local cell's forwarding signal. If both the left and right neighbor cells exceed the threshold, the right neighbor cell signal is merged into the local cell's forwarding signal. If both the left and right neighbor cells are below the threshold, only the local cell's signal is forwarded. Specifically, if the signal is above the threshold, the corresponding channel occupancy flag is set to 1; if it is below the threshold, the corresponding channel occupancy flag is set to 0. The neighbor cell anti-collision mechanism channel switch table is shown in the table below:

[0043]

[0044] In summary, the call control method for neighboring cell interconnection according to the embodiments of the present invention provides a feasible solution for private network application scenarios that require interconnection between adjacent areas in the VHF band but do not allow communication between adjacent areas. It can automatically control whether to merge with neighboring cell signals and communicate with them through thresholds, effectively preventing interference signals from neighboring cells below the threshold from merging into the main area and causing noise interference, ensuring that the main area signal is always effective, and not communicating with devices in non-adjacent areas, thus meeting the needs of specific scenarios.

[0045] In addition, the present invention also proposes a computer-readable storage medium storing a call control program for neighbor cell communication, which, when executed by a processor, implements the call control method for neighbor cell communication as described above.

[0046] In addition, this invention also proposes a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the call control method for neighbor cell interconnection as described above.

[0047] To implement the above embodiments, this invention proposes a call control device for neighboring cell interconnection, applied to a wireless communication system. The wireless communication system includes multiple optical master units. Each optical master unit is connected to the optical master unit of its left neighboring cell via a first optical port, to the optical master unit of its right neighboring cell via a fourth optical port, to multiple optical remote units within its own cell via a third optical port, and to multiple optical remote units in neighboring cells via a second optical port. Figure 5 As shown, the call control device for inter-cell communication includes: an acquisition module 10, a conversion module 20, and an inter-cell control module 30.

[0048] The acquisition module 10 is used to acquire the local area call signal, the left neighbor area call signal, and the right neighbor area call signal; the conversion module 20 is used to convert the local area call signal, the left neighbor area call signal, and the right neighbor area call signal to obtain the corresponding local area optical power value, the left neighbor area optical power value, and the right neighbor area optical power value; the interconnection control module 30 is used to compare the local area optical power value, the left neighbor area optical power value, and the right neighbor area optical power value with preset threshold values ​​to obtain the corresponding call results.

[0049] As an example, the local call signal includes the signal received by the optical master unit of the local area and the signals received by all optical remote units connected to the third optical port of the optical master unit of the local area. The left neighbor call signal includes the signal sent by the optical master unit of the left neighbor to the optical master unit of the local area through the first optical port of the optical master unit of the local area; the right neighbor signal includes the signal sent by the right neighbor to the optical master unit of the local area through the fourth optical port of the optical master unit of the local area.

[0050] As an example, the interconnection control module 30 is also used to compare the optical power value of the local area with a preset threshold value to determine the comparison result; if the comparison result is that the optical power value of the local area is higher than the preset threshold value, then only the call signal of the local area is received; if the comparison result is that the optical power value of the local area is lower than the preset threshold value, then the optical power values ​​of the left neighboring area and the right neighboring area are compared with the preset threshold values ​​respectively to obtain the corresponding call result.

[0051] As an embodiment, the interconnection control module 30 is further configured to compare the optical power values ​​of the left neighboring cell and the right neighboring cell with preset threshold values ​​respectively to determine the comparison result; if the comparison result is that the optical power values ​​of the left neighboring cell and the right neighboring cell are both lower than the preset threshold values, then only the call signal of the local cell is received; if the comparison result is that the optical power value of the left neighboring cell is higher than the preset threshold value and the optical power value of the right neighboring cell is lower than the preset threshold value, then the call signal of the local cell and the call signal of the left neighboring cell are received; if the comparison result is that the optical power value of the right neighboring cell is higher than the preset threshold value and the optical power value of the left neighboring cell is lower than the preset threshold value, then the call signal of the local cell and the call signal of the right neighboring cell are received; if the comparison result is that the optical power values ​​of the left neighboring cell and the right neighboring cell are both higher than the preset threshold values, then the call signal of the local cell and the call signal of the right neighboring cell are received.
