[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Figure 1 is a flow chart of a method for detecting wireless link failure provided by the present invention, such as Figure 1 As shown, the execution subject of the wireless link failure detection method may be an electronic device, such as a base station, etc. The method includes:

[0037] Step 101, obtaining signal to interference plus noise ratio (SINR) statistical information by periodically detecting a sounding reference signal (SRS) reported by a terminal, wherein the SINR statistical information is used to count comparison results of each period, and the comparison result is a comparison result between the SINR of each antenna port used by the SRS and a first SINR threshold;

[0038] Specifically, in order to quickly release the wireless resources occupied by the power-off terminal, the sounding reference signal (Sounding Reference Signal, SRS) reported by the terminal is periodically detected, and the comparison results of each period can be counted to obtain the signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) statistical information. In each period, the SINR of each antenna port used by the SRS can be compared with the first SINR threshold to obtain the comparison result of each period, and then the comparison result of each period can be counted to obtain SINR statistical information.

[0039] It is understandable that power failure of the terminal may lead to a radio link failure (RLF), and whether a radio link failure occurs can be determined by analyzing SINR statistical information.

[0040] Step 102: If it is determined based on the SINR statistical information that the SINR of each antenna port is less than the first SINR threshold within a continuous preset number of periods, it is determined that a radio link failure occurs in the terminal.

[0041] Specifically, the specific method of analyzing SINR statistical information can be to determine whether the SINR of each antenna port is less than the first SINR threshold within a consecutive preset number of periods. If it is determined that the SINR of each antenna port is less than the first SINR threshold within a consecutive preset number of periods, it can be determined that a wireless link failure has occurred in the terminal.

[0042] For example, the preset number can be 50, and it can be determined whether the SINR of each antenna port is less than the first SINR threshold in 50 consecutive cycles. If it is determined that the SINR of each antenna port is less than the first SINR threshold in 50 consecutive cycles, it can be determined that a wireless link failure occurs in the terminal.

[0043] The wireless link failure detection method provided by the present invention can count the comparison results of each period to obtain SINR statistical information by periodically detecting the SRS reported by the terminal. The comparison result is the size comparison result between the SINR of each antenna port used by the SRS and the first SINR threshold. Terminal power failure will cause wireless link failure. If it is determined based on the SINR statistical information that the SINR of each antenna port is less than the first SINR threshold within a continuous preset number of periods, it can be determined that the terminal has a wireless link failure, and the wireless resources occupied by the power-off terminal can be quickly released.

[0044] Optionally, the SINR statistical information includes a statistical value of each antenna port, the initial statistical value is the preset number, and the acquiring the signal to interference plus noise ratio SINR statistical information by periodically detecting a sounding reference signal SRS reported by the terminal includes:

[0045] Based on the SRS reported by the terminal, obtain the SINR of each antenna port;

[0046] Based on the first SINR threshold and the SINR of each antenna port, updating the statistical value of each antenna port;

[0047] The updating of the statistical value of each antenna port based on the first SINR threshold and the SINR of each antenna port includes:

[0048] If it is determined that the SINR of the target antenna port is less than the first SINR threshold, performing an operation of subtracting 1 from the statistical value of the target antenna port;

[0049] or, if it is determined that the SINR of the target antenna port is greater than or equal to the first SINR threshold, configuring the statistical value of the target antenna port to be the preset number;

[0050] The target antenna port is any one of the antenna ports used by the SRS.

[0051] Specifically, in order to obtain SINR statistical information, the statistical value of each antenna port can be updated in each period. In any period, the SINR of each antenna port can be obtained based on the SRS reported by the terminal, and then the SINR of each antenna port can be compared with the first SINR threshold to obtain a comparison result, and the statistical value of each antenna port can be updated based on the comparison result.

[0052] Optionally, during the comparison process, the SINR of the target antenna port may be compared with the first SINR threshold. If it is determined that the SINR of the target antenna port is less than the first SINR threshold, an operation of subtracting 1 from the statistical value of the target antenna port may be performed.

[0053] For example, the first SINR threshold may be 118. At the beginning of a comparison process, the statistical value of the target antenna port is 50. The SINR of the target antenna port may be compared with the first SINR threshold. If the SINR of the target antenna port is 100, it may be determined that the SINR of the target antenna port is less than the first SINR threshold. Then, an operation of subtracting 1 from the statistical value of the target antenna port may be performed. At the end of the comparison process, the statistical value of the target antenna port is 49.

[0054] Optionally, during the comparison process, the SINR of the target antenna port can be compared with the first SINR threshold. If it is determined that the statistical value of the target antenna port is 0 and the SINR of the target antenna port is less than the first SINR threshold, the statistical value of the target antenna port can be kept at 0 without performing an operation of subtracting 1 from the statistical value of the target antenna port.

[0055] Optionally, during the comparison process, the size relationship between the SINR of the target antenna port and the first SINR threshold can be compared. If it is determined that the SINR of the target antenna port is greater than or equal to the first SINR threshold, the statistical value of the target antenna port can be configured as the preset number.

[0056] For example, the first SINR threshold may be 118, and the preset number may be 50. At the beginning of a comparison process, the statistical value of the target antenna port is 35. The SINR of the target antenna port may be compared with the first SINR threshold. If the SINR of the target antenna port is 120, it may be determined that the SINR of the target antenna port is greater than the first SINR threshold, and the statistical value of the target antenna port may be configured to be 50.

[0057] Therefore, the statistical value of each antenna port can be updated in each cycle, and the SINR statistical information can represent the communication quality of each antenna port in several consecutive cycles. By analyzing the SINR statistical information, it can be determined whether a wireless link failure occurs.

[0058] Optionally, the determining, based on the SINR statistical information, that the SINR of each antenna port within a continuous preset number of periods is less than the first SINR threshold includes:

[0059] If it is determined that the statistical values ​​of each antenna port are all equal to 0, it is determined that the SINR of each antenna port is less than the first SINR threshold within a continuous preset number of periods.

[0060] Specifically, the specific method of analyzing SINR statistical information can be to determine whether the statistical values ​​of each antenna port are less than or equal to 0. If it is determined that the statistical values ​​of each antenna port are equal to 0, it can be determined that the SINR of each antenna port is less than the first SINR threshold within a continuous preset number of periods, and then it can be determined that a wireless link failure has occurred.

[0061] Therefore, if it is determined that the statistical values ​​of each antenna port are all equal to 0, it can be determined that a wireless link failure occurs in the terminal, and the wireless resources occupied by the powered-off terminal can be quickly released.

[0062] Optionally, the method further comprises:

[0063] If it is determined that no radio link failure occurs to the terminal based on the channel quality indicator CQI and / or uplink data sent by the terminal, the statistical value of each antenna port is configured to be the preset number.

[0064] Specifically, when the terminal communication is normal, there may be problems in the SRS decoding of the physical layer (PHY). In order to avoid this situation, the wireless link status of the terminal can be judged based on the channel quality indication (Channel Quality Indicator, CQI) and / or uplink data sent by the terminal. If it is determined that the terminal has not experienced a wireless link failure, the statistical value of each antenna port can be configured to a preset number, and then the statistical value of each antenna port is greater than 0, which can avoid using SRS for wireless link failure detection when the terminal communication is normal.

[0065] Optionally, the uplink data is data sent by the terminal based on a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). If the uplink data can be received, it can be determined that no wireless link failure has occurred in the terminal, and the statistical value of each antenna port can be configured to a preset number.

[0066] Optionally, the CQI can be sent by the terminal based on a physical uplink control channel (PUCCH), and the wireless link status of the terminal can be judged based on the received CQI. If it is determined that the terminal has not experienced a wireless link failure, the statistical value of each antenna port can be configured to a preset number.

[0067] Optionally, the radio link status of the terminal may be determined based on the CQI and the uplink data. If it is determined that no radio link failure occurs in the terminal, the statistical value of each antenna port may be configured to be a preset number.

[0068] Therefore, by judging the radio link status of the terminal based on the CQI and / or uplink data, it is possible to avoid using the SRS to perform radio link failure detection when the terminal communication is normal.

[0069] Optionally, the determining, based on a channel quality indication CQI and / or uplink data sent by the terminal, that no radio link failure occurs in the terminal includes:

[0070] If it is determined based on the CQI that the SINR of the PUCCH is greater than or equal to the second SINR threshold, it is determined that no radio link failure occurs to the terminal.

[0071] Specifically, the relationship between the SINR of the physical uplink control channel (PUCCH) and the second SINR threshold can be determined based on the CQI. If it is determined that the SINR of the PUCCH is greater than or equal to the second SINR threshold, it can be determined that no wireless link failure has occurred in the terminal. The statistical value of each antenna port can be configured to a preset number, so that the statistical value of each antenna port is greater than 0, which can avoid using SRS for wireless link failure detection when the terminal communication is normal.

[0072] For example, the second SINR threshold may be 118. If the SINR of the PUCCH is determined to be 120 based on the CQI, it can be determined that the SINR of the PUCCH is greater than the second SINR threshold, and it can be determined that no radio link failure occurs in the terminal.

[0073] Optionally, if it is determined that the CQI is non-PUSCH multiplexing and the SINR of the PUCCH determined based on the CQI is less than the second SINR threshold, it can be determined that the current terminal signal is poor or is in a disconnected state, and the radio link failure detection still uses SRS.

[0074] For example, the second SINR threshold can be 118. If the SINR of PUCCH is determined to be 100 based on CQI (the SINR of PUCCH is less than the second SINR threshold), and the CQI is determined to be non-PUSCH multiplexing, it can be determined that the current terminal signal is poor or is in a disconnected state, and the wireless link failure detection still uses SRS.

[0075] Optionally, the acquiring, based on the SRS reported by the terminal, an SINR of each antenna port includes:

[0076] Determining, based on the SRS reported by the terminal, a signal-to-noise ratio of a plurality of resource block channels corresponding to the target antenna port;

[0077] An average value of signal-to-noise ratios of multiple resource block channels is determined as the SINR of the target antenna port.

[0078] Specifically, in any period, the SINR of each antenna port can be obtained based on the SRS reported by the terminal. The target antenna port can be any one of the antenna ports used by the SRS, and the specific process of obtaining the SINR of the target antenna port can be based on the SRS reported by the terminal, and the signal to noise ratio (SNR) of multiple resource blocks (RB) channels corresponding to the target antenna port can be obtained, and then the average value can be calculated based on the SNR of multiple RB channels, and the average value is used as the SINR of the target antenna port.

[0079] Therefore, in each period, the SINR of each antenna port can be obtained by analyzing the SRS reported by the terminal, and then the statistical value of each antenna port can be updated based on the SINR of each antenna port.

[0080] The wireless link failure detection method provided by the present invention can count the comparison results of each period to obtain SINR statistical information by periodically detecting the SRS reported by the terminal. The comparison result is the size comparison result between the SINR of each antenna port used by the SRS and the first SINR threshold. Terminal power failure will cause wireless link failure. If it is determined based on the SINR statistical information that the SINR of each antenna port is less than the first SINR threshold within a continuous preset number of periods, it can be determined that the terminal has a wireless link failure, and the wireless resources occupied by the power-off terminal can be quickly released.
