[0017] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions provided by the present application will be described in detail below with reference to the drawings.

[0018] In the following, the example embodiments will be described more fully with reference to the accompanying drawings, but the described example embodiments can be embodied in different forms and should not be interpreted as being limited to the embodiments set forth herein. On the contrary, the purpose of providing these embodiments is to make the present application thorough and complete and to fully enable those skilled in the art to understand the scope of the present application.

[0019] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0020] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0021] In the following description, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration various embodiments for practicing the present application. It is to be understood that other embodiments can be utilized and structural or

[0022] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present application, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0023] In the related art, in the case of downlink communication abnormality between a terminal device and a network side device, such as poor network coverage or large network interference, in order to accurately locate where the problem occurs and at what time the problem occurs, road testing is often needed, which requires the problem to be reproduced, and this will consume a lot of manpower, material resources and financial resources; at the same time, it will also cause the interruption of normal business.

[0024] In the process of using a test terminal device to perform road testing on the area covered by the network side device, a large number of repeated test dialing, ping packets and uplink and downlink packet filling are needed to reproduce the problem and analyze the problem. However, for application scenarios with extremely high reliability and usability requirements, it is often difficult to reproduce. On the one hand, the probability of occurrence of the problem is extremely low, and the reason for the occurrence of the problem may be a probability extremely low interference on the wireless channel, which may not appear for a long time and is difficult to reproduce; on the other hand, ping packets, packet filling and the like are difficult to simulate real industrial industry applications, resulting in a large deviation between the simulated information and the real-time running information of the network. It can be seen that in the case of downlink communication abnormality, the success rate of obtaining accurate analysis results through road testing to analyze the problem of downlink communication abnormality is low due to the difficulty in reproducing the problem.

[0025] Based on this, the embodiment of the present application provides a communication parameter processing method, a communication device, a storage medium and a program product. In the case that the downlink communication service of the first terminal device fails to decode the physical downlink shared channel (PDSCH), the first terminal device acquires a target communication parameter, stores the target communication parameter, and sends the target communication parameter to the network side device in the idle state. The network side device can analyze the target communication parameter to generate an abnormal analysis result. In this way, since the target communication parameter is obtained and stored by the first terminal device in the case that the downlink communication service of the first terminal device fails to decode the physical downlink shared channel, it can reflect the real scene when the downlink communication of the first terminal device is abnormal, thereby facilitating the network side device to generate an accurate abnormal analysis result in the downlink communication abnormal analysis.

[0026] The embodiment of the present application will be described below with reference to the accompanying drawings.

[0027] As shown in FIG. 1, an architecture schematic diagram of a wireless communication system provided by the embodiment of the present application is shown. As shown in FIG. 1, the wireless communication system includes a first terminal device, a network side device, a core network and a radio access network (RAN) network management.

[0028] The core network is mainly responsible for the management and control of the entire wireless communication network in the wireless communication process, and it can transmit wireless communication signals between the network side device and the terminal device in the downlink communication process. The core network can be the core network of any generation of wireless communication system, such as the fourth generation wireless communication system (4G), the fifth generation wireless communication system (5G) or the sixth generation wireless communication system (6G).

[0029] The network side device mainly provides wireless coverage in the wireless communication process, and realizes the transmission of wireless signals between the core network and the terminal device located in the wireless coverage area (also referred to as the terminal device served by the network side device). For example, the network side device can be a base station, etc.

[0030] The first terminal device is any terminal device served by the above network side device, which can receive and send wireless communication signals. For example, the first terminal device can be a mobile phone, a tablet computer, a smart wearable device or a vehicle-mounted terminal, etc.

[0031] The radio access network network management is essentially a series of transmission entities between the service node interface (SNI) and the related user network interface (UNI), including line facilities, transmission facilities, etc., which are composed of the bearing capacity implementation system required for transmitting information services.

[0032] In the communication signal transmission process (i.e., the solid line) of the downlink communication service of the first terminal device through the network side device and the core network, if the first terminal device detects that the physical downlink shared channel demodulation decoding fails, the first terminal device acquires and stores the target communication parameter; in the case that the first terminal device is in an idle state, a parameter reporting process (i.e., the dashed line) is performed, that is, the first terminal device sends the target communication parameter to the network side device, the network side device performs communication anomaly analysis based on the target communication parameter, generates an abnormal analysis result, and sends the abnormal analysis result to the radio access network management.

[0033] Those skilled in the art can understand that the structure of the wireless communication system shown in FIG. 1 does not constitute a limitation on the embodiments of the present application, and can include more or fewer components than those shown, or combine certain components, or different component arrangements.

[0034] Based on the above wireless communication system, the following embodiments of the communication parameter processing method are proposed.

[0035] Please refer to FIG. 2, which is a flowchart of the communication parameter processing method provided by the embodiments of the present application. As shown in FIG. 2, the communication parameter processing method includes the following steps S201 to S204.

[0036] Step S201, in the case that the downlink communication service of the first terminal device fails in physical downlink shared channel demodulation decoding, the first terminal device acquires a target communication parameter.

[0037] In this step, in the process of the downlink communication service of the first terminal device, the first terminal device demodulates and decodes the received downlink communication signal in the physical downlink shared channel to convert the received downlink communication signal back to the original data symbol. When the physical downlink shared channel demodulation decoding fails, the first terminal device can determine that it has a downlink communication anomaly, such as poor network coverage or large network interference.

[0038] The first terminal device acquires the target communication parameter, which can be the communication parameter at the time when the physical downlink shared channel demodulation decoding fails as the target communication parameter; or the communication parameter at any time that meets a preset condition after the physical downlink shared channel demodulation decoding fails as the target parameter.

[0039] The above-mentioned any time that meets a preset condition can be any time within a preset period; or any time that the first terminal device is located within a preset location range, which can be a location range with a distance from the location when the physical downlink shared channel demodulation decoding fails less than or equal to a preset distance, and the like.

[0040] The target communication parameter can be any communication parameter that can be used by the network-side device to analyze the downlink communication exception. In some embodiments, to make the selection of the target communication parameter more flexible, the target communication parameter includes at least one of the following: Downlink Control Information (DCI) and Inphase Quadrature (IQ) information; cell identification code and carrier information; time; and geographic location information.

[0041] For example, in the case where the first terminal device detects that its downlink communication service has failed in physical downlink shared channel demodulation and decoding, the first terminal device acquires the cell identification code, carrier information, frame number, slot / sub-slot number, and IQ information received at the time of the failure in physical downlink shared channel demodulation and decoding, and DCI information for the physical downlink shared channel scheduled this time, and uses the acquired cell identification code, carrier information, IQ information, and DCI information as the target communication parameter. In some embodiments, the first terminal device can also acquire the time and geographic location information at the time of the failure in physical downlink shared channel demodulation and decoding and add them to the target communication parameter.

[0042] It should be noted that, to ensure the accuracy of the analysis result, in the case where the target communication parameter includes the time, the first terminal device needs to have the capability of time synchronization with the network-side device, for example, the first terminal device and the network-side device can be strictly synchronized at the microsecond level through time service such as SIB9.

[0043] In the case where the target communication parameter includes the geographic location information, the first terminal device needs to have accurate positioning capability, for example, for an outdoor scenario, the first terminal device can acquire the geographic location coordinates through the Global Positioning System (GPS) or Beidou positioning system, and for an indoor environment, the first terminal device can acquire the geographic location coordinates through Observed Time Difference of Arrival (OTDOA), thereby ensuring the accuracy of the geographic location information and the accuracy of the analysis result.

[0044] In addition, the first terminal device acquires the target communication parameter can be in the case where the first terminal device has an exception reporting function and the exception reporting function is enabled.

[0045] The first terminal device can enable the abnormal reporting function according to a user operation, or the network side device can control the first terminal device to enable the abnormal reporting function.

[0046] In some embodiments, before the first terminal device acquires the target communication parameter, the first terminal device can further receive enabling indication information sent by the network side device in the communication mode indicated by the enabling parameter, the enabling indication information being information sent when the enabling parameter indicates that the abnormal reporting function is enabled, and the first terminal device enables the abnormal reporting function in response to the enabling indication information.

[0047] The first terminal device acquires the target communication parameter, which can include: when the abnormal reporting function is enabled, the first terminal device acquires the target communication parameter.

[0048] In this embodiment, the network side device can send the enabling indication information to the first terminal device in the communication mode indicated by the enabling parameter, and the first terminal device enables the abnormal reporting function according to the sent enabling indication information, so that the network side device can control the first terminal device to enable the abnormal reporting function through different communication modes.

[0049] The enabling parameter can be a parameter pre-configured in the network side device, which can be used to indicate the communication mode and whether to enable the abnormal reporting function, that is, the network side device can send the enabling indication information to the first terminal device through different communication modes or whether to send the enabling indication information to the first terminal device according to different enabling parameters. The communication mode can be unicast or broadcast.

[0050] For example, the network side device can configure an enabling parameter physical downlink shared channel abnormal Enable in the network side device, when the enabling parameter is 1, the network side device sends the enabling indication information to the first terminal device in the broadcast mode; when the enabling parameter is 2, the network side device sends the enabling indication information to the first terminal device in the unicast mode; and when the parameter is 0, the network side device does not send the enabling indication information to the first terminal device, that is, the first terminal device is not enabled.

[0051] Correspondingly, before the first terminal device receives the enabling indication information sent by the network side device in the communication mode indicated by the enabling parameter, the method can further include: when the enabling parameter indicates that the abnormal reporting function is enabled, the network side device sends the enabling indication information to the first terminal device in the communication mode indicated by the enabling parameter, and the enabling indication information is used by the first terminal device to enable the abnormal reporting function.

[0052] In step S202, the first terminal device stores the target communication parameter.

[0053] In this step, after obtaining the target communication parameter, the first terminal device stores the target communication parameter in a cache area.

[0054] In the foregoing, the storing of the target communication parameter in the cache area can be storing the target communication parameter in any storage area of a common memory of the first terminal device, or reserving a dedicated cache area in the common storage area of the first terminal device, and storing the target communication parameter in the dedicated cache area, or configuring a dedicated memory in the first terminal device, and storing the target communication parameter in the dedicated memory.

[0055] In step S203, when the first terminal device is in an idle state, the first terminal device sends the target communication parameter to the network side device.

[0056] In the foregoing, the first terminal device in the idle state can be understood as a state in which, after the downlink communication of the first terminal device is restored to normal (i.e., the physical downlink shared channel demodulation and decoding of the downlink communication service are successful), the first terminal device and the network side device do not perform transmission of wireless communication signals.

[0057] In the foregoing, the sending of the target communication parameter by the first terminal device to the network side device can be implemented by a conventional information reporting manner, for example, the first terminal device can report the target communication parameter to the network side device by a reporting manner similar to Quality of Experience (QoE) measurement reporting.

[0058] Alternatively, in some embodiments, the sending of the target communication parameter by the first terminal device to the network side device can include: sending, by the first terminal device, a target communication request to the network side device, the target communication request being used to request establishment of a target communication link between the first terminal device and the network side device; receiving, by the first terminal device, feedback information sent by the network side device in response to the target communication request; establishing, by the first terminal device, the target communication link between the first terminal device and the network side device in response to the feedback information; and sending, by the first terminal device, the target communication parameter to the network side device on the target communication link.

[0059] In this embodiment, the first terminal device in the idle state can establish the target communication link between the first terminal device and the network side device through the target communication request, and send the target communication parameter to the network side device through the target communication link, so that a special communication link can be temporarily established for the reporting of the target communication parameter, and the reliability of the reporting of the target communication parameter can be ensured.

[0060] The target communication request can be information for requesting to establish a target communication link with the network-side device. For example, the target communication request can be information for requesting to establish a radio resource control (RRC) with the network-side device, and in this case, the target communication link is an RRC link.

[0061] After the first terminal device sends the target communication request to the network-side device, the network-side device can determine whether to establish a target communication link with the first terminal device based on the received target communication request, and send feedback information to the first terminal device if it is determined that the target communication link can be established with the first terminal device. Of course, if the network-side device determines that the target communication link cannot be established with the first terminal device, the network-side device can not respond to the target communication request.

[0062] The network-side device determining whether to establish a target communication link with the first terminal device can be authenticating the first terminal device according to the target communication request. For example, the target communication request can carry a reporting function enable identifier of the first terminal device. If the reporting function enable identifier is "1", it indicates that the first terminal device abnormally enables the reporting function, and in this case, the network-side device determines to establish a target communication link with the first terminal device. If the reporting function enable identifier is "0", it indicates that the first terminal device abnormally disables the reporting function, and in this case, the network-side device does not respond to the target communication request.

[0063] Of course, the network-side device determining whether to establish a target communication link with the first terminal device can also be according to other information, for example, according to a service type of a downlink communication service, or according to running state information of the network-side device, etc.

[0064] After the first terminal device establishes a target communication link with the network-side device, the first terminal device can establish a resource bearer on the target communication link and send target communication parameters to the network-side device on the resource bearer.

[0065] For example, in the case where the target communication link is an RRC link, the first terminal device can establish a data radio bearer (DRB) in the RRC link and send target communication parameters to the network-side device on the data radio bearer, or establish a signalling radio bearer (SRB) in the RRC link and send target communication parameters to the network-side device on the signalling radio bearer.

[0066] Correspondingly, before the first terminal device sends the target communication parameter to the network side device on the target communication link, the method can further include: the network side device receiving a target communication request sent by the first terminal device, the target communication request being used to request to establish a target communication link with the network side device; the network side device sending feedback information to the first terminal device in response to the target communication request; and the network side device receiving the target communication parameter sent by the first terminal device on the target communication link, the target communication link being a communication link established by the first terminal device with the network side device in response to the feedback information.

[0067] It should be noted that after the first terminal device successfully sends the target communication parameter to the network side device, the first terminal device can delete the stored target communication parameter, so as to store a new communication parameter when the next sent downlink communication is abnormal.

[0068] Correspondingly, after the first terminal device sends the target communication parameter, the network side device receives the target communication parameter sent by the first terminal device in the idle state.

[0069] In step 204, the network side device performs communication anomaly analysis on the downlink communication service based on the target communication parameter, and generates an anomaly analysis result.

[0070] In this step, after the network side device receives the target communication parameter, the network side device can perform communication anomaly analysis on the downlink communication service based on the target communication parameter according to a configured communication anomaly analysis strategy, and generate an analysis result.

[0071] In some embodiments, when the target communication parameter includes downlink control information and in-phase quadrature information, the network side device performing communication anomaly analysis on the downlink communication service based on the target communication parameter, and generating an anomaly analysis result, can include: the network side device determining a signal to interference plus noise ratio (SINR) of a physical downlink shared channel based on the downlink control information and the in-phase quadrature information; and the network side device determining an anomaly analysis result including first analysis information based on the signal to interference plus noise ratio, the first analysis information being used to indicate that the first terminal device is abnormal.

[0072] In this embodiment, the network side device can determine the signal to interference plus noise ratio of the physical downlink shared channel according to the downlink control information and the in-phase quadrature information reported by the first terminal device, and determine whether the first terminal device is abnormal according to the signal to interference plus noise ratio, thereby realizing diagnosis of whether the occurrence of the downlink communication anomaly is caused by the abnormality of the first terminal device.

[0073] The network-side device determines the signal-to-interference-plus-noise ratio of the physical downlink shared channel based on the downlink control information and the in-phase / quadrature information.

[0074] The network-side device determines the abnormality analysis result including the first analysis information based on the signal-to-interference-plus-noise ratio. The network-side device can compare the signal-to-interference-plus-noise ratio with a preset threshold. If the signal-to-interference-plus-noise ratio is lower than the preset threshold, it is determined that the first terminal device is abnormal, and the first analysis information is generated.

[0075] The first terminal device abnormality can be that the wireless channel of the first terminal device is interfered, or the antenna of the first terminal device is damaged, etc.

[0076] It should be noted that, since the abnormality analysis result includes the first analysis information, the first terminal device can be diagnosed according to the first analysis information. For example, the first terminal device can be instrumentally tested to determine whether the first terminal device has a problem. If the first terminal device has no problem, it is determined that the wireless channel is interfered or is temporarily blocked, and the network-side device coverage and possible external interference in the corresponding time period can be investigated.

[0077] In some embodiments, the target communication parameter further includes time and geographic location information. In the case that the target communication parameter includes the downlink control information, the in-phase / quadrature information, the time and the geographic location information, before the network-side device determines the signal-to-interference-plus-noise ratio of the physical downlink shared channel based on the downlink control information and the in-phase / quadrature information, the network-side device can further query alarm information in the network-side device based on the time and the geographic location information. The alarm information is used to indicate whether the network-side device has an alarm.

[0078] The network-side device determines the signal-to-interference-plus-noise ratio of the physical downlink shared channel based on the downlink control information and the in-phase / quadrature information. The network-side device can determine the signal-to-interference-plus-noise ratio of the physical downlink shared channel based on the downlink control information and the in-phase / quadrature information in the case that no alarm information is queried in the network-side device.

[0079] In this embodiment, the network-side device only determines the signal-to-interference-plus-noise ratio based on the downlink control information and the in-phase / quadrature information in the case that no corresponding alarm information is queried, i.e., the abnormality diagnosis of the first terminal device is performed, so that the frequent abnormality diagnosis of the first terminal device can be reduced, and the computing resources in the downlink communication abnormality analysis can be saved.

[0080] The network-side device queries the alarm information in the network-side device based on the time and geographic location information. Once an abnormal alarm occurs in the network-side device, alarm information indicating an alarm time and an alarm geographic location coordinate is generated and stored. When the network-side device receives the time and geographic location information sent by the first user terminal device, the network-side device matches the received time and geographic location information with the alarm time and the alarm geographic location coordinate indicated by the stored alarm information, respectively, to determine whether the matching alarm information can be queried in the network-side device.

[0081] In some embodiments, after the network-side device queries the alarm information in the network-side device based on the time and geographic location information, the network-side device further determines an abnormal analysis result including second analysis information in the case that the alarm information is queried in the network-side device. The second analysis information is used to indicate that the network-side device is abnormal.

[0082] In the embodiment, in the case that the corresponding alarm information can be queried, the network-side device determines the abnormal analysis result including the second analysis information to indicate that the network-side device is abnormal through the second analysis information, thereby realizing the diagnosis of whether the downlink communication abnormality is caused by the network-side device abnormality.

[0083] In some embodiments, the network-side device determining the abnormal analysis result including the second analysis information can include: the network-side device acquiring Hybrid Automatic Repeat Request (HARQ) failure information corresponding to the alarm information. The HARQ failure information is used to indicate whether the HARQ is successful before reaching the maximum number of retransmissions. If the HARQ failure information indicates that the HARQ is successful before reaching the maximum number of retransmissions, the network-side device determines the abnormal analysis result including the second analysis information.

[0084] It should be noted that, since the abnormal analysis result includes the second analysis information, the network-side device can be diagnosed according to the second analysis information, for example, the downlink communication abnormality caused by the device problem, the interference problem of the wireless channel, or the problem of the receiver, etc.

[0085] In some embodiments, the alarm information is further used to indicate that the occurred alarm is a radio frequency alarm, and the second analysis information is specifically used to indicate that the network-side device has a radio frequency processing abnormality. Alternatively, the alarm information is further used to indicate that the occurred alarm is an antenna alarm, and the second analysis information is specifically used to indicate that the network-side device has an antenna abnormality.

[0086] In the embodiment, when the alarm information is determined to be related to the radio frequency processing abnormality or the antenna abnormality, the network-side device can be determined to have an abnormality.

[0087] In some embodiments, when the target communication parameter comprises at least one of the time and the geographic location information, the network-side device performs the communication abnormality analysis on the downlink communication service based on the target communication parameter to generate the abnormality analysis result, which can comprise: generating the abnormality analysis result comprising a target image based on at least one of the time and the geographic location information, the target image being used to reflect the association between the physical downlink shared channel demodulation decoding failure of the downlink communication service and the space-time.

[0088] In the embodiment, the target image can be generated based on the time and the geographic location information reported by the first terminal device, so that the analysis on the downlink communication abnormality in the space-time can be realized.

[0089] The target image can be any image capable of reflecting the association between the physical downlink shared channel demodulation decoding failure of the downlink communication service and the space-time.

[0090] For example, when the target communication parameter comprises the time, the target image can be a two-dimensional coordinate scatter plot of the time and the reason of the downlink communication abnormality, each coordinate point in the two-dimensional coordinate scatter plot representing one downlink communication abnormality of a terminal device served by the network-side device, as shown in FIG. 3, three coordinate points in the two-dimensional coordinate scatter plot representing three downlink communication abnormalities with different reasons occurring at different times; or, when the target communication parameter comprises the time and the geographic location information, the target image can be a three-dimensional coordinate scatter plot of the time and the geographic location coordinates, each coordinate point in the three-dimensional coordinate scatter plot representing one downlink communication abnormality of a terminal device served by the network-side device, as shown in FIG. 4, three coordinate points in the three-dimensional coordinate scatter plot representing three downlink communication abnormalities occurring at different times and different location coordinates.

[0091] In some embodiments, when the target communication parameter comprises the cell identification code and the carrier information, the network-side device performs the communication abnormality analysis on the downlink communication service based on the target communication parameter to generate the abnormality analysis result, which comprises: the network-side device determining the abnormality analysis result comprising the abnormality times of the cell or the carrier associated with the target communication parameter based on the target communication parameter.

[0092] In the embodiment, the network-side device can determine the abnormality times of the associated cell based on the cell identification code uploaded by the first terminal device, or determine the abnormality times of the associated carrier based on the carrier information, so as to realize the analysis on the downlink communication abnormality of the cell or the carrier.

[0093] The abnormal analysis result determined based on the target communication parameter includes an abnormal number of cells or carriers associated with the target communication parameter. The network side device receives the target communication parameter reported by different terminal devices, indexes the cells and carriers with cell identifiers and carrier information, and identifies the number of problems (i.e., the abnormal number) in the cells and carriers based on the geographic coordinate plane as the coordinate system. In some embodiments, the network side device can also perform data analysis and different dimension presentations based on the obtained data.

[0094] It should be noted that in the case where the target communication parameter includes time, if the network side device has the ability to perform downlink communication abnormal analysis based on time, the network side device needs to be time-synchronized with the first terminal device, for example, the network side device and the first terminal device are strictly synchronized to the microsecond level through time service such as SIB9.

[0095] In addition, the network side device performs communication abnormal analysis on the downlink communication service based on the target communication parameter. The network side device can perform communication abnormal analysis as long as it receives the target communication parameter under any circumstances.

[0096] In some embodiments, before the network side device performs communication abnormal analysis on the downlink communication service based on the target communication parameter and generates the abnormal analysis result, the network side device can also receive the reporting capability information sent by the first terminal device. The reporting capability information is used to indicate whether the first terminal device has an abnormal reporting function.

[0097] The network side device performs communication abnormal analysis on the downlink communication service based on the target communication parameter and generates the abnormal analysis result. This can include the network side device performing communication abnormal analysis on the downlink communication service based on the target communication parameter and generating the abnormal analysis result when the first terminal device has an abnormal reporting function.

[0098] In this embodiment, the network side device can only perform downlink communication abnormal analysis when the reporting capability information sent by the first terminal device indicates that the first terminal device has an abnormal reporting function, thereby reducing the load of the network side device.

[0099] Correspondingly, when the network side device receives the reporting capability information sent by the first terminal device, the method can also include that the first terminal device sends the reporting capability information to the network side device. In the case where the first terminal device has an abnormal reporting function, the reporting capability information is used for the network side device to perform communication abnormal analysis on the downlink communication service based on the target communication parameter.

[0100] After the network-side device generates the above abnormality analysis result, the network-side device can only send the abnormality analysis result to a radio access network management, so as to prompt the radio access network management to perform abnormality troubleshooting.

[0101] In some embodiments, after the network-side device performs the communication abnormality analysis on the downlink communication service based on the target communication parameter and generates the abnormality analysis result, the network-side device further generates abnormality avoidance information based on the abnormality analysis result, the abnormality avoidance information being used to instruct a second terminal device to avoid the physical downlink shared channel demodulation and decoding failure in the downlink communication service, the second terminal device being any terminal device served by the network-side device.

[0102] In the embodiment, the network-side device can generate the abnormality avoidance information based on the abnormality analysis result, so as to instruct the terminal device served by the network-side device to avoid the physical downlink shared channel demodulation and decoding failure in the downlink communication service, thereby reducing the possibility of the physical downlink shared channel demodulation and decoding failure of the terminal device served by the network-side device.

[0103] The network-side device generates the abnormality avoidance information based on the abnormality analysis result, which can be in response to the abnormality analysis result, for the time slot position where the downlink communication abnormality occurs, the network-side device generates the abnormality avoidance information used to instruct to avoid scheduling at the time slot position; or, according to the geographical position where the downlink communication abnormality occurs, the network-side device generates the abnormality avoidance information used to instruct to switch the second terminal device to other network-side device located outside the geographical position; or, in the case that the second terminal device navigates, the network-side device generates the abnormality avoidance information used to instruct to avoid the navigation route of the geographical position where the downlink communication abnormality occurs, and the like.

[0104] It should be noted that the above second terminal device can be any terminal device served by the network-side device, which can be a terminal device other than the first terminal device, or can be the first terminal device, which is not limited herein.

[0105] For the convenience of understanding the processing method of the communication parameter of the present application, two practical application examples are provided herein to explain the processing method of the test signal of the embodiment of the present application, which are as follows:

[0106] Application Example One: the base station (i.e. the network-side device) enables the terminal (i.e. the first terminal device) through a broadcast mode

[0107] The terminal supports PDSCH abnormality reporting (i.e. has the abnormality reporting function), the base station configures to support the corresponding reporting processing, and the base station sends a broadcast message, and all terminals supporting the function can report to the base station.

[0108] The terminal performs related downlink service in a cell with a cell identification code of 3.

[0109] When the terminal is out of order, the scheduled PDSCH is on carrier 1, the resource of frame number 5, slot 3, assuming that the baseband processing of the terminal is 2048 sampling points per OFDM symbol, each sampling point has IQ two-way, and the number of quantization bits of the sample is 14 bits, and it is assumed that the PDSCH is composed of 12 orthogonal frequency division multiplexing (OFDM) symbols. Then the terminal needs to buffer the number of bits of the IQ is 14*2048*12*2 = 685128 bits.

[0110] When the terminal side performs downlink communication service, the terminal stores the information of the problematic PDSCH, and when the terminal can synchronously obtain the time and the geographical position, the data information at the time of the problem is stored in the format of table 1. Among them, the format of the data reported by the terminal (i.e. target communication parameter) can be as follows:

[0111] Table 1: data reported by the terminal

[0112] When the terminal needs to report this information, the terminal initiates an RRC establishment request with the base station in the idle state, and the establishment reason is PDSCH demodulation abnormal (for PDSCH abnormal);

[0113] The base station replies to the terminal to establish RRC connection;

[0114] The terminal replies to the base station that the RRC establishment is completed;

[0115] The terminal reports the related information of the table to the base station on the established SRB. The terminal can delete the data about the successfully reported information in order to write the information of the problematic PDSCH;

[0116] The base station receives the PDSCH abnormal information;

[0117] The base station processes the obtained information and gives a diagnosis conclusion;

[0118] Using the scheduling information of DCI, the received IQ is demodulated, the downlink SINR is calculated, and according to the time and geographical position at the time of failure, combined with the alarm of the base station and the downlink HARQ failure, the diagnosis conclusion is given by comparison and analysis. Specifically as follows:

[0119] If at this time, the base station has a remote radio unit (RRU) and other radio frequency alarms, it is concluded that it is a problem of radio frequency processing;

[0120] If at this time, there is an alarm of the base station antenna, it is analyzed that it is a problem of the base station antenna;

[0121] If the radio frequency and the antenna have no above-mentioned alarm, the calculated SINR of the PDSCH is low, and the diagnosis is that the wireless channel has interference or the antenna of the terminal is damaged.

[0122] For the terminal, this can be instrumentally tested, and problems can be found.

[0123] If the terminal has no problem, it is that the wireless channel has interference or instantaneous shielding. It is suggested to check the base station coverage and possible external interference in the corresponding time period.

[0124] The diagnosis conclusion is used to guide the problem solving of the base station and the terminal, and before solving, the normal operation of the service is ensured through the avoidance strategy.

[0125] When new information about the PDSCH is collected, the above process is repeated.

[0126] Application Example Two, the base station enables a specific terminal (i.e. the first terminal device) through RRC configuration

[0127] The terminal initiates a downlink service establishment request;

[0128] The base station replies to the terminal to establish the RRC connection;

[0129] The terminal reports that it has the PDSCH abnormal reporting capability;

[0130] The base station reconfigures the terminal through RRC, configures the terminal to enable PDSCH abnormal reporting, requires the terminal to record the related PDSCH abnormal data, and reports the related data on the corresponding DRB;

[0131] The terminal performs downlink service and monitors the PDSCH demodulation, monitors the IQ of the PDSCH demodulation failure, when the time and geographical position can be obtained at the same time, the UE records and stores the related PDSCH abnormal data in the Operation and Maintenance (OAM) protocol, and the data format is shown in Table 2 below:

[0132] Table 2: Data reported by the terminal

[0133] The terminal reports the recorded data on the corresponding dedicated DRB; the base station receives the OAM data on the DRB, and can perform corresponding problem analysis on the computing module or computing hardware of the base station, or can perform analysis on the network management, and then give a conclusion; the UE erases the data that has been successfully reported to the base station after the current downlink service ends; and the UE enters the idle state again.
