Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a wiring detection method, device and medium based on a pico base station system. Background Technology

[0002] A pico base station system includes a baseband unit (BBU), a radio switch (Radio-HUB, RHUB), and a pico-remote radio unit (pRRU). The RHUB is the aggregation network element, typically connecting to multiple pRRU devices. Each pRRU is powered via a power cable and connected to each pRRU via fiber optic cables. It is crucial that the power cables and fiber optic cables of each remote port of the RHUB be connected in pairs to the same pRRU; misconnecting the power cables and fiber optic cables of different pRRUs out of order is strictly prohibited.

[0003] In related technologies, during actual engineering construction, due to objective factors of the construction environment and occasional negligence by construction personnel, the power cord and fiber optic cable of the pRRU may be incorrectly connected. Usually, all the remote ports under the RHUB will be full of devices. When the power cord and fiber optic cable of the pRRU device are not connected correctly, it may cause network failure when the wrong device is operated during subsequent operation, such as resetting or powering off the device. This problem is usually hidden and currently relies on manual inspection, which makes it difficult to find and the labor cost of inspection is high. Summary of the Invention

[0018] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0019] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0020] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0021] The technical solutions provided in this disclosure can be applied to a variety of systems. For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems and their evolved communication systems, and 6G (sixth generation mobile communication technology) systems. These systems may include terminal equipment and network equipment. The systems may also include a core network component, such as the Evolved Packet Core (EPC) or the 5G Core Network (5GC).

[0022] In the pico base station system of this disclosure embodiment, there is a baseband unit (BBU), one or more remote aggregation units (RHUBs), and multiple radio frequency remote units (pRRUs). The RHUB is connected to the BBU via an uplink optical fiber and is connected to multiple pRRUs via power lines and optical fibers on multiple remote ports. The method is applied to the RHUB.

[0023] As mentioned in the examples above, in modern communication systems, picocells, as small wireless access points, are widely used in densely populated urban areas, indoor coverage, and areas where cabling is difficult. A typical picocell network configuration includes a baseband unit (BBU), one or more remote aggregation units (RHUBs), and multiple remote radio units (pRRUs). This structure, connected by optical fibers, separates signal processing from transmission, optimizing resource allocation and signal coverage.

[0024] Specifically, the BBU is responsible for baseband signal processing and control management, while the RHUB acts as an intermediate node, connected to the BBU via its uplink fiber optic port and providing power output ports and fiber optic interfaces via its remote ports, which are connected to each pRRU. These pRRU devices are responsible for transmitting and receiving wireless signals; they are powered by the RHUB and use it for data backhaul.

[0025] The RHUB has an uplink fiber optic port for connecting to the BBU. The remote port has a power output port and a fiber optic interface, connected to each pRRU. The power output port supplies power to the pRRU, and the fiber optic interface is used to transmit optical link data between the pRRU and the RHUB. Once the equipment is deployed and powered on, the RHUB supplies power to the pRRU. After the pRRU starts up normally, because the RHUB's remote optical port is connected to the pRRU's optical port, the RHUB can receive optical signals from the pRRU, and the pRRU can also receive optical signals from the RHUB.

[0026] In practical use, the power supply lines and fiber optic cables of each remote port of the RHUB should be connected in pairs to the same pRRU. It is strictly forbidden to connect the power supplies and fiber optic cables of different pRRUs out of pair order. Connecting the power supply line of RHUB remote port 1 to one pRRU and the fiber optic cable to another pRRU 2 is a wiring error. However, in actual engineering construction, due to the complexity of the construction site, the variability of the construction environment, and operator errors, pRRU power supply lines and fiber optic cables may be incorrectly connected. Often, all the remote ports under the RHUB will be fully connected to devices. When the power supply and fiber optic cables of some pRRU devices are not properly connected, troubleshooting will be very difficult in subsequent use.

[0027] Current troubleshooting methods for such wiring errors primarily rely on on-site operations by engineers. This involves engineers manually disconnecting the pRRU's power cord on-site (RHUB or pRRU side) and then observing which corresponding pRRU on the BBU side is offline to determine if the wiring is incorrect. For example, manually disconnecting the power supply to remote port 1 on the RHUB side and waiting one minute to check if pRRU 1 registered on the BBU side is still online. If pRRU 1 is offline, it proves that the power supply and fiber optic connection of pRRU 1 are correctly connected. If, after disconnecting the power supply to remote port 1 on the RHUB, pRRU 1 is still online after one minute, while another remote port pRRU is offline, it indicates that the fiber optic cable and power cord of remote port pRRU 1 are definitely connected incorrectly and need to be readjusted. This process needs to be repeated several times for each remote port, significantly increasing the time cost. With all remote ports fully connected to pRRUs, and starting from when a person can easily reach the RHUB side, it would take at least half an hour to complete the detection of all remote port wiring abnormalities. If uncontrollable factors such as the lack of cooperation from some building property staff are present, this detection and troubleshooting time will be greatly extended.

[0028] To overcome these limitations and address the issues of low efficiency and difficulty in troubleshooting, this disclosure provides an automated wiring detection method from the RHUB. By controlling the RHUB, it automatically detects wiring errors in the power cables and fiber optic cables of each pRRU device, determines whether there are abnormal power / fiber optic connections between the RHUB and the pRRU, and reports the detection results to the BBU, thereby significantly improving detection efficiency and accuracy and reducing maintenance costs. In general, in this disclosure, by powering down each pRRU device, the voltage and current of its power supply ports are detected and compared with the initial state before power-off. The comparison results are recorded to determine which ports have mismatched power cables and fiber optic cables, and finally, the detection results are reported to the BBU. This automated method not only solves the problems of high manual operation costs, difficulty in accessing construction areas, limited troubleshooting conditions, and low efficiency, but also avoids field signal anomalies caused by wiring errors, thereby ensuring service stability and continuity.

[0029] Furthermore, the embodiments of this disclosure require minimal on-site personnel when checking for wiring errors. Multiple operators are not needed simultaneously; only one person is required to issue wiring detection commands to the RHUB from the BBU side. After the wiring detection commands are issued, the RHUB automatically operates the power supply ports of each remote port. The power-off and optical port reception status polling checks for each remote port can be completed within seconds, and all power supply and fiber optic connection errors for all remote ports can be detected within 30 seconds. The extremely short time and high efficiency significantly reduce the difficulty and time required to troubleshoot wiring errors.

[0030] The following describes a wiring detection method for a picocell base station system according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0031] Figure 1 This is a flowchart illustrating a wiring detection method for a pico base station system provided in an embodiment of this disclosure. The pico base station system includes: a baseband unit (BBU), one or more remote aggregation units (RHUBs), and multiple remote radio units (pRRUs). The RHUBs are connected to the BBUs via uplink optical fibers and are connected to the multiple pRRUs via power lines and optical fibers on multiple remote ports. This method can be executed by a wiring detection device based on the pico base station system, which can be implemented in software and / or hardware and is generally integrated into the RHUB. Figure 1 As shown, the method mainly includes:

[0032] Step 101: Receive the wiring detection command issued by the BBU.

[0033] It should be understood that in actual networking scenarios, such as Figure 2As shown, multiple RHUBs can be connected to the BBU, and multiple pRRUs can be connected to each RHUB. The BBU can issue wiring detection commands. As one possible embodiment, after the BBU receives the RHUB wiring completion message, it receives the first wiring detection command issued by the BBU after receiving the RHUB wiring completion message. This first wiring detection command can be issued actively by the BBU, or it can be sent by relevant technical personnel who connect to the BBU through management software on the BBU device side, check the current RHUB wiring completion status on the BBU, and control the BBU to send it.

[0034] In some possible embodiments, after the BBU receives the RHUB wiring abnormality message, it can receive a second wiring detection command issued by the BBU after receiving the RHUB wiring abnormality message. This second detection command can be issued proactively by the BBU, or it can be sent by a relevant technician who connects to the BBU via management software on the BBU side, checks the current RHUB wiring abnormality on the BBU, and then controls the BBU to send it.

[0035] Step 102: Check whether the power supply port corresponding to each remote port has power, and whether the fiber optic port corresponding to each remote port has light.

[0036] In this embodiment, in response to the received wiring detection command, it is detected whether the power supply port corresponding to each remote port has power and whether the fiber optic port corresponding to each remote port has light.

[0037] It's easy to understand that once every device in the system starts up normally, the remote port of the HUB corresponding to each pRRU device can be detected as having power, and the fiber optic port connected to the RHUB side for this pRRU device can be detected as receiving light normally. For example, if a pRRU is connected to an RHUB, and the pRRU's power supply and fiber optic cables are correctly connected and paired to the power supply and fiber optic ports of the RHUB's remote port 1, then the status of the RHUB's remote port 1 will be detected as having power and light. If the power and fiber optic ports of the other remote ports of the RHUB are not connected to pRRUs, their status will be detected as having no power and no light. Therefore, in this embodiment, by first detecting whether the power supply port corresponding to the remote port has power and whether the fiber optic port corresponding to each remote port has light, a preliminary determination is made as to whether there is a wiring mismatch.

[0038] Step 103: Based on the detection results, power off the power supply ports of the powered targets respectively, and determine the target fiber optic port that changes from having light to having no light after power off each target power supply port.

[0039] In this embodiment, if a power supply port is without power, the corresponding remote port is not in use, and therefore, no further testing is performed on it. Therefore, in this embodiment, the target power supply port with power is first tested based on the test results obtained above.

[0040] It's easy to understand that if the pRRU's power cord and fiber optic cable are properly connected to the RHUB's remote port 1, the initial detection of the remote port's status will show it as powered and optical. If the power to the RHUB's remote port 1 is then turned off, and the receiving status of the RHUB's remote port 1 is re-detected, the receiving status of this RHUB's remote port will change to no light because the pRRU is powered off. If this change in power supply status and the change in receiving status detected by the RHUB side are both on the same remote port, then it can be determined that the power supply and fiber optic cable of this remote port are correctly connected in a one-to-one correspondence. Conversely, if a pRRU is connected to an RHUB, but the power cord and fiber optic cable are not paired and are incorrectly connected (for example, the pRRU's power cord is connected to the power supply port of RHUB's remote port 1, while the pRRU's fiber optic cable is connected to the fiber optic port of RHUB's remote port 2), then the status of RHUB's remote port 1 will be detected as powered but without light, while the status of remote port 2 will be detected as without power but with light (the light is present because the pRRU's power cord is connected to the power supply port of RHUB's remote port 1, therefore, the power supply port of remote port 1 is powered, and this type of incorrect connection can also be detected based on the detection of the powered target power supply port). If the power supply port of remote port 1 is de-energized, then the light receiving status of RHUB's remote port 1 will be re-detected. Since the pRRU's fiber optic cable is connected to the fiber optic port of RHUB's remote port 2, the light receiving status of this RHUB's remote port will not change to no light.

[0041] In the embodiments of this disclosure, by performing power-off operations on the target power supply ports that are energized, and determining the target optical fiber port that changes from having light to not having light after the power-off of each target power supply port, wherein the target optical fiber port is obviously the optical fiber port that supplies power to the target power supply port.

[0042] Step 104: Detect whether the target remote port corresponding to the power supply port of the target that is powered off is the remote port corresponding to the target fiber optic port.

[0043] In the embodiments of this disclosure, it is detected whether the target remote port corresponding to the power supply port of the power-off target is the same remote port as the target optical fiber port, that is, it is determined whether the target optical fiber port powered by the target power supply port belongs to the same remote port.

[0044] It should be noted that the methods for detecting whether the target remote port corresponding to the target power supply port that has lost power is the same as the target fiber optic port in different application scenarios are as follows:

[0045] In some possible embodiments, the remote ports are pre-numbered, with different numbers for different remote ports. Thus, detecting whether the target remote port corresponding to the power supply port that has been de-energized is the same as the target fiber optic port can include: obtaining a first number of the target remote port and a second number of the remote port corresponding to the target fiber optic port; comparing whether the first number and the second number are consistent; if they are consistent, it indicates that the power supply line and fiber optic cable of the target remote port are properly matched and connected, and the target remote port is determined to be the remote port corresponding to the target fiber optic port; if they are inconsistent, it indicates that there is an incorrect connection between the power supply and fiber optic cable of the target remote port, and the target remote port is determined not to be the remote port corresponding to the target fiber optic port.

[0046] In some possible embodiments, the power supply port identifier of the target power supply port and the fiber optic port identifier of the target fiber optic port are obtained, and a remote port query request carrying the power supply port identifier and the fiber optic port identifier is sent to the BBU. The BBU queries the pre-registered information according to the request to determine the remote port A corresponding to the power supply port identifier and the remote port B corresponding to the fiber optic port identifier. If A and B are consistent, the detection result is that the target remote port is the remote port corresponding to the target fiber optic port.

[0047] Step 105: Based on the test results, determine whether the power cable and fiber optic cable of the target remote port are correctly connected to the pRRU, and report back to the BBU.

[0048] If the detection results determine that the target remote port is the same remote port as the target fiber optic port, then they are considered to belong to the same remote port. Therefore, the power cable and fiber optic cable of the target remote port are correctly connected to the pRRU. Conversely, if the detection results determine that the target remote port is not the same remote port as the target fiber optic port, then they are considered to belong to different remote ports. Therefore, the power cable and fiber optic cable of the target remote port are incorrectly connected to the pRRU. In this embodiment, the detection results are used to determine whether the power cable and fiber optic cable of the target remote port are correctly connected to the pRRU, and this information is then fed back to the BBU.

[0049] For example, if the pRRU's power cable and fiber optic cable are not properly matched and connected to the same remote port of the RHUB—for instance, the pRRU's power cable is connected to remote port 1 of the RHUB, while the fiber optic cable is connected to remote port 2—and power is turned off to remote port 1 of the RHUB, the received light status detected by remote port 1 will not change. If the changes in power supply status and received light status detected by the RHUB are not on the same remote port, it can be determined that the power cable and fiber optic cable of this remote port are not properly matched, meaning the power cable and fiber optic cable are incorrectly connected to the pRRU.

[0050] The above detection method can also be used to determine which two remote ports' power cables and fiber optic cables are incorrectly connected together. In this embodiment, if the remote ports are pre-numbered, determining whether the power cable and fiber optic cable of the target remote port are correctly connected to the pRRU based on the detection results and feeding back to the BBU may include: if it is determined that the target remote port is the remote port corresponding to the target fiber optic port, then it is determined that the power cable and fiber optic cable of the target remote port are correctly connected to the pRRU, and a correct connection message containing the first number is sent to the BBU; if it is determined that the target remote port is not the remote port corresponding to the target fiber optic port, then it is determined that the power cable and fiber optic cable of the target remote port are incorrectly connected to the pRRU, and a connection error message containing the correspondence between the first number and the second number is sent to the BBU, where the first number is marked as the power supply port and the second number is marked as the fiber optic port. Based on the first number and the second number, the incorrectly connected power supply port and fiber optic port can be identified. The above incorrect connection situations can be recorded according to the rule of [Power Supply Port Number: Fiber Optic Port Number]. The corresponding incorrect connection record can be retrieved on the BBU's management page for quick connection restoration.

[0051] Therefore, in the embodiments of this disclosure, an automated wiring detection is implemented. The BBU issues a wiring detection command to the RHUB, which then executes the aforementioned automated detection algorithm to quickly detect any incorrect connections. If incorrect connections are found, the corresponding relationships between the incorrect connections are quickly detected and obtained. This solves the problems of inconvenience, high labor costs, and inability to conduct manual on-site inspections according to the time requirements of maintenance personnel in the prior art.

[0052] In summary, the wiring detection method for a pico base station system disclosed in this embodiment includes a baseband unit (BBU), one or more remote aggregation units (RHUBs), and multiple remote radio units (pRRUs). The RHUBs are connected to the BBU via uplink optical fibers and to multiple pRRUs via power lines and optical fibers on multiple remote ports. The RHUBs receive wiring detection commands from the BBU, detect whether the power supply port corresponding to each remote port is powered, and whether the optical fiber port corresponding to each remote port is optical. Based on the detection results, power is cut off to the powered target power supply ports, and the target optical fiber port corresponding to each target power supply port changes from optical to optical after power-off is determined. The method also detects whether the target remote port corresponding to the power-off target power supply port is the same as the target optical fiber port. Furthermore, based on the detection results, it determines whether the power lines and optical fibers of the target remote ports are correctly connected to the pRRUs and feeds this information back to the BBU. This technical solution achieves low-cost automatic troubleshooting of wiring disorder between the RHUB and pRRU network elements.

[0053] Based on the above embodiments, when detecting whether the power supply port corresponding to each remote port has power and whether the optical fiber port corresponding to each remote port has light, the remote ports can be detected in any order. For example, in some possible embodiments, the remote ports can be polled and monitored in turn according to their order.

[0054] In this embodiment, as Figure 3 As shown, the detection process includes checking whether the power supply port corresponding to each remote port has power, and whether the fiber optic port corresponding to each remote port has light, including:

[0055] Step 301: Initialize the status of each remote port to the undetected state, and start from the first remote port to detect the power supply port and fiber optic port corresponding to each remote port in sequence.

[0056] In this embodiment, to avoid duplicate detection and ensure comprehensive detection, a state is used to identify whether each remote port is being detected. For example, a state value can be used to indicate whether each remote port is being detected. During initial detection, the state of each remote port is initialized to the undetected state, and the power supply port and fiber optic port corresponding to each remote port are detected sequentially, starting from the first remote port.

[0057] Step 302: If the power supply port of the currently detected remote port has an output voltage and the optical fiber port has received an optical signal, then the current state of the detected remote port is recorded as a powered and optical state.

[0058] Step 303: If the power supply port of the currently detected remote port has an output voltage and the fiber optic port does not receive an optical signal, then the current state of the detected remote port is recorded as "powered but no light".

[0059] Step 304: If the power supply port of the currently detected remote port has no output voltage and the fiber optic port does not receive an optical signal, then record the current state of the detected remote port as a state of no power and no light.

[0060] Step 305: If the power supply port of the currently detected remote port has no output voltage, and the fiber optic port receives an optical signal, then record the current state of the detected remote port as "no power, light present".

[0061] If the power supply port of the currently detected remote port has an output voltage and the fiber optic port receives an optical signal, then the current status of the detected remote port is recorded as "Powered and Light-on". If the power supply port of the currently detected remote port has an output voltage but the fiber optic port does not receive an optical signal, then the current status of the detected remote port is recorded as "Powered but No Light". If the power supply port of the currently detected remote port has no output voltage and the fiber optic port does not receive an optical signal, then the current status of the detected remote port is recorded as "No Power and No Light". If the power supply port of the currently detected remote port has no output voltage but the fiber optic port receives an optical signal, then the current status of the detected remote port is recorded as "No Power but Light". The remote ports are polled starting from the first port (represented by the number 1) to query its power supply status (powered if there is external power supply, no power if there is no power supply) and light reception status (light received if light is received, no light if light is not received). Each remote port can have one of four states: powered and illuminated, powered but not illuminated, not powered but illuminated, and not powered and not illuminated. In this embodiment, the state of each remote port can be polled once, and all states of powered and illuminated, powered but not illuminated, and not powered but illuminated can be recorded in an array.

[0062] In this embodiment, power-off operations are performed on the target power supply ports that are powered, based on the detection results. The target fiber optic port that changes from having light to having no light after power-off is determined for each target power supply port. This includes: querying the status of each remote port sequentially starting from the first remote port. If the current remote port status is no power and no light or no power and light, the process jumps directly to the next remote port for re-judgment. That is, when there is no power and no light, it indicates that the corresponding remote port is not in use, and no further detection is performed. The process jumps directly to the next remote port for re-judgment. When there is no power and light, it indicates that the power supply port of the corresponding remote port is not powered, and the light is caused by the power supply of other remote ports. Therefore, when judging other remote ports, this situation can be detected. At this time, there is no need to repeat the judgment, and the process jumps directly to the next remote port for re-judgment.

[0063] If the current remote port status is either powered and optical or powered but not optical, then the current power supply port of the remote port is determined as the target power supply port, and the target power supply port is powered off. Then, after the target power supply port is powered off, the remote ports whose previous status records were powered and optical or not powered but optical are traversed, and the target fiber optic port that changed from optical to not optical is determined.

[0064] In this embodiment, when the power supply port of the target is turned off, the pRRU connected to this remote port is powered down. The pRRU cannot receive or emit light. The remote ports that were previously recorded as having power and light or having no power and light on the RHUB will inevitably become in a state of no light. Thus, the target fiber optic port that changes from having light to no light can be identified.

[0065] If the optical port that went into a no-light state and the target power supply port that just experienced a power outage both belong to the same remote port, then the wiring of this target remote port is correct. If the remote port containing the target optical port that went into a no-light state and the remote port containing the target power supply port that experienced a power outage do not belong to the same remote port, then the wiring is incorrect. Record the remote port numbers of the power supply port that experienced the power outage and the optical port that went into a no-light state. Then restore power to the remote port polled in this instance.

[0066] For example, refer to Figure 4 The state of each remote port is initialized to the undetected state. Starting from the first remote port, the power supply port and fiber optic port corresponding to each remote port are detected in sequence. It is detected whether the power supply port corresponding to each remote port has power and whether the fiber optic port corresponding to each remote port has light. The state of each remote port may be one of the following four: power and light, power but no light, no power but light, and no power and no light.

[0067] After determining the status of each remote port, check if the number of remote ports being detected is greater than the maximum number of remote ports. If it is, it means that the status of all remote ports has been detected. Otherwise, continue to traverse the remote ports to ensure that the status of all remote ports can be determined.

[0068] After all status checks are completed, starting from the first remote port, the status of each remote port is queried in turn. If the current remote port status is no power and no light or no power but light, then directly jump to the next remote port to re-judge. If the current remote port status is power and light or power but no light, then determine the current remote port's power supply port as the target power supply port and disconnect the power to the target power supply port. After the target power supply port is disconnected, traverse the remote ports whose previous status records were power and light or no power but light, and determine the target fiber optic port that changes from light to no light.

[0069] Next, check whether the target remote port corresponding to the power supply port that is de-energized is consistent with the remote port corresponding to the target fiber optic port. If they are inconsistent, it indicates a wiring error. Record the remote port number of the power supply port that is de-energized and the remote port number of the optical port that has become non-light. The recording format can be [power supply port number; optical port number].

[0070] If they match, it indicates that the wiring is correct. Then, the remote port is powered on. It is further determined whether the number of remote ports being detected is greater than the maximum number of remote ports. If it is greater than the maximum number of remote ports, it indicates that all remote ports have been detected. If it is not greater than the maximum number of remote ports, the next remote port is detected and its status is recorded as either powered and lit or powerless and lit.

[0071] In summary, the wiring detection method based on a pico base station system disclosed in this embodiment can perform wiring detection on each remote port in a polling manner, ensuring the comprehensiveness of the measurement and avoiding measurement duplication.
