[0001] The present invention relates to the field of mobile communication technologies, and in particular to a 5G networking communication method and system. Background Art

[0002] Thanks to the support of 5G technology and the continuous advancement of intelligent construction, mining work has undergone tremendous changes. In recent years, the use of 5G communication technology has continuously enabled the mining industry to achieve modernization, transformation and upgrading, and used the power of communication to promote the high-quality development of my country's energy industry.

[0003] 5G mining base stations are designed for special scenarios such as underground workers, coal mines, and tunnels. As a communication system for controlling underground construction and communicating with underground workers, its stability and high availability are directly related to production efficiency and production safety. In order to adapt to the mining environment, which is mostly in the form of long tunnels or deep shafts, RRU adopts cascade networking for direct connection. Each level of RRU can serve as a transmission relay between the lower-level RRU and BBU to reduce the difficulty of transmission wiring. However, this RRU cascade networking solution also has defects. If one of the front-level RRUs has abnormal transmission or equipment failure, all RRUs cascaded behind it will not be able to be used normally, which will pose a major threat to production efficiency and production safety. Summary of the invention

DETAILED DESCRIPTION

[0009] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0010] Please refer to Figure 1 , a 5G networking communication method, comprising the steps of: S1. The RRU obtains the communication status of its own uplink port and downlink port, determines whether the communication status of the uplink port is normal, and if so, performs cascade communication with the BBU through the uplink port; otherwise, determines whether the communication status of the downlink port is normal, and if so, performs cascade communication with the BBU through the downlink port; The BBU is provided with at least two OP ports, which are respectively connected to the uplink port of the first-stage RRU and the downlink port of the last-stage RRU in the cascaded multiple RRUs.

[0011] From the above description, it can be seen that the beneficial effects of the present invention are: a 5G networking communication method of the present invention, in which the BBU is connected to the uplink port of the first-level RRU and the downlink port of the last-level RRU in the cascaded RRU, thereby forming a ring network, and a mechanism for detecting the status of the forward and reverse backup links is set. When the forward link is abnormal and the reverse backup link is detected to be available, the forward link is closed and the reverse backup link is enabled. Even if one of the RRUs fails, resulting in the inability to communicate in the forward link of itself and the lower-level RRU, communication can be carried out through the reverse link, which greatly improves the availability of the communication system.

[0012] Furthermore, before step S1, the following steps are also included: S0, RRU detects the communication status of the uplink port and the downlink port according to the preset frequency, and records the communication status of the uplink port and the downlink port in a preset status register according to the detection result; In step S1, the RRU obtains the communication status of its uplink port and downlink port as follows: The RRU reads the communication status of the uplink port and the downlink port from the status register.

[0013] From the above description, it can be seen that the RRU detects the communication status of the uplink port and the downlink port at a preset frequency and records the detection results in the status register. When selecting a communication link, it only needs to be based on the value recorded in the status register without temporary detection, thereby ensuring the timeliness of communication.

[0014] Furthermore, step S0 is specifically as follows: The RRU detects the communication status of the uplink and downlink ports at a preset frequency: If the uplink port communicates normally and the downlink port communicates normally, recording a first preset value in the status register; If the uplink port communication is abnormal and the downlink port communication is normal, recording a second preset value in the status register; If the uplink port communication is normal and the downlink port communication is abnormal, recording a third preset value in the status register; If the uplink port communication is abnormal and the downlink port communication is abnormal, a fourth preset value is recorded in the status register.

[0015] It can be seen from the above description that the first preset value, the second preset value and the third preset value are used to distinguish the available states of the uplink port and the downlink port.

[0016] Furthermore, step S1 is specifically as follows: The RRU reads the communication status of the uplink port and the downlink port from the status register, and determines whether the communication status of the uplink port is normal according to the data in the status register. If normal, the forward link register is set to a start value and the reverse link register is set to a shutdown value, so as to perform cascade communication with the BBU through the uplink port; Otherwise, the reverse link register is set to a start value and the forward link register is set to a stop value, so as to perform cascade communication with the BBU through the downlink port.

[0017] Furthermore, the startup value is 0x1, and the shutdown value is 0x0.

[0018] From the above description, it can be seen that the forward link register and the reverse link register are respectively set for the activation status of the uplink port and the downlink port, and the usage of the uplink port and the downlink port is determined by the values ​​of the forward link register and the reverse link register.

[0019] Please refer to Figure 2 A 5G networking communication system includes a BBU and a plurality of cascaded RRUs, wherein the BBU is provided with at least two OP ports, which are respectively connected to an uplink port of the first-stage RRU and a downlink port of the last-stage RRU in the cascaded multiple RRUs, and each of the RRUs implements the following steps: S1. Obtain the communication status of its own uplink port and downlink port, determine whether the communication status of the uplink port is normal, if normal, perform cascade communication with the BBU through the uplink port, otherwise determine whether the communication status of the downlink port is normal, if normal, perform cascade communication with the BBU through the downlink port.

[0020] From the above description, it can be seen that the beneficial effects of the present invention are: a 5G networking communication system of the present invention is connected by the BBU and the uplink port of the first-level RRU and the downlink port of the last-level RRU in the cascaded RRU, thereby forming a ring network, and a mechanism for detecting the status of the forward and reverse backup links is set. When the forward link is abnormal and the reverse backup link is detected to be available, the forward link is closed and the reverse backup link is enabled. Even if one of the RRUs fails, resulting in the inability to communicate in the forward link of itself and the lower-level RRU, communication can be carried out through the reverse link, which greatly improves the availability of the communication system.

[0021] Furthermore, the RRU is provided with a status register, and before step S1, the following steps are also included: S0, RRU detects the communication status of the uplink port and the downlink port according to the preset frequency, and records the communication status of the uplink port and the downlink port in a preset status register according to the detection result; In step S1, the RRU obtains the communication status of its uplink port and downlink port as follows: The RRU reads the communication status of the uplink port and the downlink port from the status register.

[0022] From the above description, it can be seen that the RRU detects the communication status of the uplink port and the downlink port at a preset frequency and records the detection results in the status register. When selecting a communication link, it only needs to be based on the value recorded in the status register without temporary detection, thereby ensuring the timeliness of communication.

[0023] Furthermore, step S0 is specifically as follows: The RRU detects the communication status of the uplink and downlink ports at a preset frequency: If the uplink port communicates normally and the downlink port communicates normally, recording a first preset value in the status register; If the uplink port communication is abnormal and the downlink port communication is normal, recording a second preset value in the status register; If the uplink port communication is normal and the downlink port communication is abnormal, recording a third preset value in the status register; If the uplink port communication is abnormal and the downlink port communication is abnormal, a fourth preset value is recorded in the status register.

[0024] It can be seen from the above description that the first preset value, the second preset value and the third preset value are used to distinguish the available states of the uplink port and the downlink port.

[0025] Furthermore, the RRU is also provided with a forward link register and a reverse link register; Step S1 is specifically as follows: The RRU reads the communication status of the uplink port and the downlink port from the status register, and determines whether the communication status of the uplink port is normal according to the data in the status register. If normal, the forward link register is set to a start value and the reverse link register is set to a shutdown value, so as to perform cascade communication with the BBU through the uplink port; Otherwise, the reverse link register is set to a start value and the forward link register is set to a stop value, so as to perform cascade communication with the BBU through the downlink port.

[0026] Furthermore, the startup value is 0x1, and the shutdown value is 0x0.

[0027] From the above description, it can be seen that the forward link register and the reverse link register are respectively set for the activation status of the uplink port and the downlink port, and the usage of the uplink port and the downlink port is determined by the values ​​of the forward link register and the reverse link register.

[0028] A 5G networking communication method and system of the present invention is suitable for 5G networking communication within a region, and is particularly suitable for scenarios such as well workers, coal mines, and tunnels that require high availability and stable communications to carry out construction and communication work to ensure work safety.

[0029] Please refer to Figure 1 as well as Figures 3 to 6 , Embodiment 1 of the present invention is: A 5G networking communication method, comprising the steps of: The BBU is provided with at least two OP ports, which are respectively connected to the uplink port of the first-stage RRU and the downlink port of the last-stage RRU in the cascaded multiple RRUs.

[0030] S0, RRU detects the communication status of the uplink port and the downlink port according to the preset frequency, and records the communication status of the uplink port and the downlink port in a preset status register according to the detection result; Specifically, the RRU detects the communication status of the uplink port and the downlink port according to the preset frequency: If the uplink port communicates normally and the downlink port communicates normally, recording a first preset value in the status register; If the uplink port communication is abnormal and the downlink port communication is normal, recording a second preset value in the status register; If the uplink port communication is normal and the downlink port communication is abnormal, recording a third preset value in the status register; If the uplink port communication is abnormal and the downlink port communication is abnormal, a fourth preset value is recorded in the status register.

[0031] In this embodiment, 0x57 is used as the status register, and the 0x57 register has four conditions: 0x0 (communication abnormality of both upper and lower ports), 0x1 (communication normal of the upper port, communication abnormality of the lower port), 0x2 (communication normal of the lower port, communication abnormality of the upper port), and 0x3 (communication normal of both upper and lower ports). Whether each RRU enables the forward or reverse link is determined independently based on the value of the 0x57 register of each RRU, and the forward link is enabled by default.

[0032] S1. The RRU obtains the communication status of its own uplink port and downlink port, determines whether the communication status of the uplink port is normal, and if so, performs cascade communication with the BBU through the uplink port; otherwise, determines whether the communication status of the downlink port is normal, and if so, performs cascade communication with the BBU through the downlink port; Step S1 is specifically as follows: The RRU reads the communication status of the uplink port and the downlink port from the status register, and determines whether the communication status of the uplink port is normal according to the data in the status register. If normal, the forward link register is set to a start value and the reverse link register is set to a shutdown value, so as to perform cascade communication with the BBU through the uplink port; Otherwise, the reverse link register is set to a start value and the forward link register is set to a stop value, so as to perform cascade communication with the BBU through the downlink port.

[0033] In this embodiment, each RRU determines whether the uplink and downlink ports of the RRU can communicate normally with the OP port of the BBU according to the value of register 0x57, with b0 representing the uplink port (the value 0x1 represents normal communication, and the value 0x0 represents abnormal communication), and b1 represents the downlink port (the value 0x1 represents normal communication, and the value 0x0 represents abnormal communication).

[0034] In the RRU, registers 0x20 and 0x30 represent the forward link and reverse link enabled status (i.e., forward link register and reverse link register), both 0x0 represents off, and 0x1 represents on. The so-called forward link refers to the communication between BBU and RRU first through the RRU uplink port, and then through the RRU downlink port to cascade the next level RRU. The reverse link refers to the communication between BBU and RRU first through the RRU downlink port, and then through the RRU uplink port to cascade the next level RRU.

[0035] The default state of the ring networking function is off, that is, each RRU turns off the reverse link and enables the forward link by default. The 0x20 register value is 0x1, and the 0x30 register value is 0x0. The 0x57 register of each RRU is tested at a certain time period. When the forward link communication of the uplink port is detected to be abnormal, and the reverse link communication of the downlink port is detected to be normal, the ring networking function will be enabled to turn off the forward link 0x20 register value to 0x0, turn on the reverse link 0x30 register value to 0x1, and quickly restore communication. It copes well with the communication system abnormalities caused by individual RRU communication or equipment failure under the 5G mine base station RRU cascade, ensuring the high availability of the entire 5G mine RRU cascade communication system.

[0036] In this embodiment, the following is an example of how to handle a specific fault when using the system: First, four RRUs are connected to a ring network according to the improved method. The first RRU on the forward link is connected to OP1 on the BBU side, and the last RRU is connected to OP2 on the BBU side. The final online available network diagram is as follows: Figure 3 shown.

[0037] Simulate three possible fault conditions and trigger the ring networking function to achieve the following results: (1) Transmission failure between the first RRU uplink port and the OP1 interface All RRU forward links fail while reverse links are normal. The register 0x57 periodic detection value is 0x2, triggering the ring networking function. The forward link register 0x20 is set to 0x0 to disable, and the reverse link register 0x30 is set to 0x1 to enable. The four RRUs connect to the OP2 port of the BBU through the reverse link to complete the cascade recovery communication. The networking communication is as follows: Figure 4 shown.

[0038] (2) Transmission failure between the first RRU downlink port and the second RRU uplink port The periodic detection value of the 0x57 register of the first RRU is 0x1, the uplink communication is normal, and the downlink communication is abnormal. The ring networking function is not enabled, and the register 0x20 value is 0x1. The forward link is still used to connect to the OP1 interface of the BBU.

[0039] The periodic detection value of the 0x57 register of the second to fourth RRU is 0x2, the communication of the uplink port is abnormal, and the communication of the downlink port is normal. The ring networking function is enabled, the forward link register 0x20 value is set to 0x0, and the reverse link register 0x30 is set to 0x1. The second to fourth RUU uses the reverse link to connect to the OP2 port of the BBU to complete the cascade recovery communication.

[0040] Network communication such as Figure 5 shown.

[0041] (3) The second RRU loses power or loses connection due to equipment failure. The periodic detection value of the 0x57 register of the first RRU is 0x1, the uplink communication is normal, and the downlink communication is abnormal. The ring networking function is not enabled, and the register 0x20 value is 0x1. The forward link is still used to connect to the OP1 interface of the BBU.

[0042] The periodic detection value of the 0x57 register of the third and fourth RRUs is 0x2, indicating abnormal communication at the uplink port and normal communication at the downlink port. The ring networking function is enabled, the forward link register 0x20 value is set to 0x0, and the reverse link register 0x30 is set to 0x1. The third and fourth RUUs use the reverse link to connect to the OP2 port of the BBU to complete the cascade recovery communication.

[0043] Network communication such as Figure 6 shown.

[0044] Please refer to Figure 2 , Embodiment 2 of the present invention is: A 5G networking communication system comprises a BBU and a plurality of cascaded RRUs, wherein the BBU is provided with at least two OP ports, which are respectively connected to an uplink port of the first-stage RRU and a downlink port of the last-stage RRU in the cascaded multiple RRUs, the RRU is provided with a status register, a forward link register and a reverse link register, and each of the RRUs implements the steps in a 5G networking communication method of the above embodiment 1.

[0045] In summary, the present invention provides a 5G networking communication method and system, in which the BBU is connected to the uplink port of the first-level RRU and the downlink port of the last-level RRU in the cascaded RRU to form a ring network, and a mechanism for detecting the status of the forward and reverse backup links is set. When the forward link is abnormal and the reverse backup link is detected to be available, the forward link is closed and the reverse backup link is enabled. Even if one of the RRUs fails, resulting in the inability to communicate in the forward link of itself and the lower-level RRU, communication can be carried out through the reverse link, which greatly improves the availability of the communication system.

[0046] The present invention adopts a ring network and adds a forward and reverse link communication detection mechanism. When the forward link communication is abnormal and the reverse link communication is normal, it can automatically switch, skip the optical fiber or RRU with abnormal communication, and automatically restore the 5G communication system in a short time. In the "smart mine" scenario, it can timely and effectively guarantee the communication channels between staff and the monitoring of intelligent mining equipment under the mine. It ensures the high availability of the entire 5G mine RRU cascade communication system, effectively ensuring the efficiency and safety of mine production.
