Description

Technical Field

[0001] The present invention relates to an antenna signal monitoring method, in particular to a 5G network indoor antenna signal monitoring method. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] With the development of large-scale 5G network construction, 5G network has formed a scale, wireless network traffic, especially 5G traffic, mainly occurs indoors, and the construction of 5G network indoor distribution system has been fully completed or started. Traditional passive indoor distribution system has the characteristics of easy construction, convenient expansion, and no need for power supply, and has been widely used. In the 2G / 3G / 4G era, a large number of traditional passive indoor distribution systems have been built. Making full use of these passive indoor distribution system resources of the existing network, co-building and sharing, and carrying out the construction of 5G network indoor distribution system can greatly reduce the difficulty of property coordination and construction, activate existing resources, and promote 5G network construction quickly and at low cost. Making full use of existing passive indoor distribution system resources to achieve low-cost and efficient 5G network coverage has the advantages of simple design and construction, low difficulty in property coordination, passive, power-saving, low investment, and quick results. It can quickly achieve deep indoor coverage of 5G network, enhance the competitiveness of operators' 5G, and become the main way to build 5G indoor distribution system. In traditional passive indoor distribution systems, a large number of passive devices, antennas, and feeders are used, with many nodes and complex network distribution. The entire system cannot be effectively monitored, which makes it difficult to discover and locate faults. It is impossible to perform prior monitoring, which easily leads to complaints and maintenance difficulties. The system is basically in an invisible, unmanageable, and uncontrollable state. Especially when co-construction and sharing have become the mainstream and direction of 5G network indoor distribution network construction, once a network problem occurs, it will have a huge impact.

[0004] The existing passive distribution system monitoring methods mainly include indoor signal monitoring systems composed of RFID test signal generators, card readers, combiners, and data and application platforms. This monitoring method has problems such as large investment, inability to monitor full-band signals, the need to transform the existing indoor distribution system, large insertion loss, and the impact of RFID cards on antenna signal transmission, which invisibly increases the number of fault points and is limited in its promotion; the indoor signal monitoring system composed of monitoring terminals based on MODEM signal acquisition and operation and maintenance centers has large investment, inability to monitor full-band signals, the monitoring effect is affected by MODEM performance, and the system's own monitoring terminals face fault points, so its application is also limited. The full spectrum access of 5G networks involves a wide frequency range, covering 700MHz to 3600MHz, and these monitoring technologies can no longer meet the requirements of full-band monitoring.

When the number of frequencies in which the antenna signal frequency power state is abnormal in the collected frequency band exceeds the antenna signal power abnormal frequency quantity threshold, the antenna signal frequency power state of the frequency band is determined to be abnormal, otherwise the state is normal, including the antenna signal power abnormal frequency quantity threshold 1 to the antenna signal power abnormal frequency quantity threshold N, where N is equal to the number of scanned frequency bands;

[0129] Step 2 includes: initializing frequency power abnormality counter 1 to frequency power abnormality counter N, with an initial value of 0; initializing antenna signal frequency power status flag 1 to antenna signal frequency power status flag N, with an initial value of normal; initializing antenna signal frequency power abnormality status counter 1 to antenna signal frequency power abnormality status counter N, with an initial value of 0; N is equal to the number of scanned frequency bands.

[0138] Step 4-2, the monitoring device compares the collected wireless signal frequency power values ​​in the frequency band with the frequency power abnormality threshold of the frequency band one by one, and when the wireless signal frequency power value is lower than the frequency power abnormality threshold, starts the frequency power abnormality counter of the corresponding serial number and accumulates the count;

[0141] Step 4-5, when the number of scanned frequency bands is not zero, the number of scanned frequency bands is reduced by one, and scanning, monitoring and collection of the next frequency band are carried out, and step 3 is executed;

[0142] Step 4-6, start the next frequency band scanning monitoring and collection process, when the frequency band scanning times is not equal to zero, execute step 3; otherwise execute step 5.

[0143] Furthermore, the process of starting the abnormal state judgment process of the scanning frequency power in step 4-4 includes:

[0144] Step 4-4-1, in the frequency band, counting the number of abnormal frequencies whose frequency power abnormality counter value is higher than or equal to a preset frequency power abnormality number threshold of the corresponding sequence number;

[0145] Step 4-4-2, when the number of abnormal frequencies is greater than or equal to a certain proportion of the total number of scanned frequencies in the frequency band, the antenna signal frequency power state of the frequency band is set to an abnormal state, otherwise the antenna signal frequency power state of the frequency band is set to a normal state;

[0146] Step 4-4-3, when the antenna signal frequency power state of the frequency band is abnormal, the antenna signal frequency power abnormal state counter of the frequency band is increased by one;

[0147] Furthermore, the next frequency band scanning monitoring and collection process started in step 4-6 includes:

[0148] Step 4-6-1, when the antenna signal frequency power state of the frequency band is abnormal, if the antenna signal frequency power state flag of the frequency band is normal, the antenna signal frequency power state flag of the frequency band is set to be abnormal, and the number of frequency band scans is equal to the number of abnormal confirmation scans;

[0149] Step 4-6-2, when the frequency band scanning times is not equal to zero, the frequency band scanning times is reduced by one;

[0150] Step 4-6-3, when the frequency band scan times is equal to zero, the antenna signal frequency power abnormal state counter of the frequency band is greater than or equal to the antenna signal power abnormal frequency number threshold, then the antenna signal frequency power state of the frequency band is abnormal, otherwise the antenna signal frequency power state of the frequency band is normal;

[0151] Step 4-6-4, when the frequency band scanning times is not equal to zero, and when the antenna signal frequency power state of the frequency band is abnormal, delay the frequency abnormality scanning interval.

[0152] In step 5, after the monitoring device reports the antenna signal frequency power status, antenna signal frequency and its power value, and monitoring working mode to the operation and maintenance system, the monitoring device enters a sleep state to achieve maximum energy saving; the monitoring device has a timed wake-up function, and periodically reads the monitoring strategy configured by the operation and maintenance system from the non-volatile register of the monitoring device.
