LTE paging The Long Term Evolution (LTE) system has a paging function. The paging function is that the UE needs to go to a specific location to receive information that the network is looking for the UE. The specific location is the Paging Frame (PF) / Paging Occasion (PO). Among them, the calculation formula for PF is: SFN mod T = (T div N) * (UE_ID mod N) (1) The index i_s pointing from the subframe pattern defined in 7.2 to the PO will be obtained from the following calculation: i_s = floor(UE_ID / N) mod Ns (2) Paging occasion: The subframe that may contain the paging message of the terminal. Paging frame: The radio frame in which the user sends the paging message, which may contain one or more POs. When discontinuous reception (DRX) is enabled, in order to save power, the terminal only listens to its own POs within the DRX cycle. The frame number ranges from 0 to 1023. UE_ID: IMSI MODE 1024, that is, it can be divided into 1024 groups according to IMSI. T: DRX cycle, with values rf32, rf64, rf128, rf256, and the parameter is configured by the high-layer RRC layer. i_s: The subframe mode of the PO, obtained by querying the table in Section 7.2. nB: 4T, 2T, T, T / 2, T / 4, T / 8, T / 16, T / 32. Among them, nB is used to indicate the paging density. The larger the value of nB, the greater the paging density. For example, nB = 4 indicates that there are 4 POs in one radio frame. When it is less than 1, it is controlled by Ns. N: min(T, nB). Ns: max(1, nB / T), with values of 1, 2, or 4. The paging density configuration Ns = 1 indicates that there is 1 paging PO in one radio frame, and 2 indicates that there are 2 POs. 2. NR paging The paging idea of NR is similar to that of LTE, but NR has new variables introduced. The calculation of PF and PO has slight changes. The SFN of PF is determined by the following formula: (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N) (3) i_s represents the index of the PO, determined by the following formula: i_s = floor(UE_ID / N) mod Ns (4) For example, the PF_offset parameter is added to the formula for calculating PF. PF_offset is the calculation offset for determining the position of the paging frame (PF). PF_offset: The offset used for PF determination. The following parameters are used to calculate the above PF and i_s: T: The DRX cycle of the UE (T is determined by the shortest among the UE-specific DRX values (if configured by RRC or upper layers) and the default DRX value broadcast in the system information. If the UE-specific DRX is not configured by RRC or upper layers, the default value is applied). N: The total number of paging frames in T. Ns: The number of paging occasions of PF. PF_offset: The offset used for PF determination. UE_ID: 5G-S-TMSI module 1024. The values of the parameters Ns, firstPDCCH-MonitoringOccasionOfPO, nAndPagingFrameOffset, and the length of the default DRX cycle are signaled in SIB1. The values of N and PF_offset are derived from the parameter nAndPagingFrameOffset defined in TS 38.331 [3]. If the UE does not have a 5G-S-TMSI, for example, when the UE has not yet registered to the network, the UE shall use UE_ID = 0 in the above PF and i_s formulas as the default identifier. 5G-S-TMSI is a 48-bit long bit string defined in TS23.501

[0010] In the above formula, 5G-S-TMSI shall be interpreted as a binary number, where the leftmost bit represents the most significant bit. In NR Rel-15 / 16, the DRX cycle of the terminal in the idle state and the inactive state is at most 2.56 s. To further reduce the power consumption of the terminal, Rel-17 introduces eDRX, which can support longer DRX cycles. 3. Paging Early Indication (PEI) For a UE in the idle state, the UE needs to measure the Synchronization Signaling Block (SSB) and receive paging within each paging cycle. Paging reception includes the UE listening for the paging Physical Downlink Control Channel (PDCCH) on its associated Paging Opportunity (PO), and then further receiving the paging Physical Downlink Shared Channel (PDSCH) after detecting the paging PDCCH. Among them, multiple UEs are associated with one PO. Therefore, a UE may be woken up by mistake because other UEs in the same group are paged and then listen for the paging PDCCH and paging PDSCH until it is confirmed that the UE-ID of the UE is not in the paging PDSCH, and then the UE will stop listening. Therefore, since the UE detects the paging PDCCH / PDSCH in each paging cycle and there are multiple associated UEs in a PO group, the UE may be woken up by mistake, resulting in unnecessary listening power consumption of the terminal. To reduce the power consumption of the terminal, the R17 standard further introduces PDCCH-based Paging Early Indication (PEI) information. The UE first receives the Paging Early Indication (PEI) information before receiving the paging PDCCH. The UE determines whether it needs to listen for the subsequent paging PDCCH according to the content indicated in the PEI DCI of the paging early indication. The specific process is shown in the following figure. The advantage is that the UE can judge in advance whether it needs to receive the paging PDCCH according to the PEI. If the PEI indicates that the UE does not receive the paging PDCCH, then the UE does not need to detect one or more SSBs between the PEI and the PO subsequently, thus achieving power savings. In addition, the PEI also has the function of further grouping and indicating the UE group of a PO. For example, the PEI is associated with and indicates a PO. 8-bit information is carried in the PEI for further UE grouping indication of the PO. Each bit corresponds to a subgroup, that is, a total of 8 subgroups of early paging indication can be indicated. Thus, the UEs associated with a PO are further divided into 8 subgroups, and the PEI indication is performed for each subgroup, which can reduce the probability of the UE being woken up by mistake, thereby reducing the paging listening power consumption of the UE. Referring to Figure 2, a schematic diagram of the structure of a PEI is shown. The specific PDCCH-based PEI indication field is shown in Figure 2: In Figure 2, one PEI indicates 4 PO indexes 0 to 3, and each PO can be divided into a maximum of 8 subgroups. RAN2 defines two subgroup grouping methods: 1) CN assigned subgrouping The core network can allocate a subgroup ID (between 0 and 7) to the UE through NAS signaling. 2) UE_ID based subgrouping SubgroupID = (floor(UE_ID / (N*Ns)) mod subgroupsNumForUEID) + (subgroupsNumPerPO - subgroupsNumForUEID) (5) The definitions in 38.304 for the following parameters: N: The total number of paging frames in T. Ns: The number of paging attempts of PF. UE_ID: 5G - S - TMSI mod X, where X is 32768 (if eDRX is applied); otherwise, X is 8192. subgroupsNumPerPO: The total number of groups on a PO. subgroupsNumForUEID: The number of subgroups of the UE_ID - based subgrouping in a PO, broadcast in the system information. As an example, a PEI subgroup can be divided into a maximum of 8 groups on a PO. If it is UE_ID based subgrouping, it is to modulo the subgroup number by UE_ID (but when a cell supports both CN grouping and UE_ID based grouping, the CN grouping number is in the front. For example, if a cell has a total of 6 groups and the UE_ID occupies 4 groups, then the CN - assigned ones are 0, 1, and the UE_ID based ones are 2, 3, 4, 5. So after modulo calculation, the CN grouping number needs to be added. For example, if the modulo calculation results in 0 groups, then add the CN grouping number, so it is 2); if it is CN - assigned, the CN directly tells the UE which group it is. Further, combined with the UE - ID based subgrouping in PEI, see how the subgroup further groups these UE - IDs. The UE - ID based grouping is supported by default for the terminal. 4. Low power wake up signal (LP - WUS) A low-power receiver, namely a low-power wake-up radio (LP-WUR) or an almost zero-power wake-up radio (AZP-WUR). Referring to Figure 3, a schematic structural diagram of a low-power receiver is shown. The basic working principle of the LP-WUR is that the terminal includes a first module and a second module. Specifically, as shown in Figure 3, the first module is the main communication module (in this application, also referred to as the main receiver) for transceiver of mobile communication data, and the second module is the low-power receiving module (also referred to as the low-power wake-up receiving module) (in this application, also referred to as the WUR receiver) for receiving wake-up signals. The terminal turns on the low-power receiving module to monitor the LP-WUS and turns off the main communication module in the energy-saving state. When downlink data arrives, the network sends a wake-up signal to the terminal. After the terminal monitors the wake-up signal through the low-power receiving module and makes a series of judgments, it triggers the main communication module to turn on from the off state, and at this time, the low-power receiving module enters the off state from the working state. The low-power wake-up receiving module can be continuously turned on or intermittently turned on, and can receive low-power wake-up signals when turned on. To reduce the receiving activities of the terminal in the standby state, so that the Radio Frequency (RF) and Baseband (MODEM) modules are truly turned off, thereby greatly reducing the power consumption of communication reception, it can be achieved by introducing an almost "zero" power receiver in the receiving module of the terminal. This almost "zero" power receiver does not require complex signal detection (such as amplification, filtering, quantization, etc.) of the RF module and signal processing of the MODEM, but only relies on passive matched filtering and signal processing with relatively low power consumption. On the base station side, by triggering the wake-up signal on-demand, the almost "zero" power receiver can be activated to obtain the activation notice, thereby triggering a series of processes inside the terminal, such as turning on the radio frequency transceiver and baseband processing modules. This wake-up signal is usually some relatively simple on-off keying signals. Referring to Figure 4, a schematic diagram of the time-domain pattern of an on-off keying signal is shown. As shown in Figure 4, the receiver can obtain the wake-up notice through simple energy detection and possible subsequent sequence detection and identification processes. In addition, while the terminal turns on the low-power wake-up receiver to receive the wake-up signal, the main receiver module can maintain a relatively low power consumption level to work, so as to achieve power saving by receiving the wake-up signal. The low-power wake-up signal can carry a small amount of payload, such as 10-bit information. The reception of the low-power wake-up signal can be applied to terminals in the RRC_idle / inactive state or to terminals in the RRC_connected state, thereby achieving energy saving for the terminals. For example, for a terminal in the RRC_idle / inactive state, the terminal can first listen for the LP-WUS signal to determine whether to listen for the PEI or Paging DCI. The following will, with reference to the accompanying drawings, through some embodiments and their application scenarios, elaborate in detail on the method for determining paging failure provided by the embodiments of the present application. The embodiments of the present application provide a method for determining paging failure. Referring to FIG. 5, a flowchart of a method for determining paging failure provided by the embodiments of the present application is shown. This method is applied to a terminal device. As shown in FIG. 5, the method may specifically include: Step 101, the terminal device sends first information to the network-side device; Step 102, the terminal device receives the paging transmission information sent by the network-side device; the paging transmission information is used to indicate at least one of the paging transmission time and the paging transmission mechanism of the network-side device; Step 103, the terminal device determines the paging failure reason according to the paging transmission information. It should be noted that the paging failure in the present application includes the event that the terminal device fails to normally receive the paging message from the network-side device for various reasons (such as network deployment, paging configuration, signal quality, UE-side processing ability, etc.), or the event that the network-side device fails to normally receive the response of the terminal device to the paging message. In one implementation, the first information is determined by the terminal device according to the recorded log data. After the terminal device sends the first information to the network-side device, the network-side device filters out the corresponding paging transmission information according to the first information and promptly sends the paging transmission information to the terminal device. The paging transmission information is used to indicate at least one of the paging transmission time and the paging transmission mechanism of the network-side device. Based on the paging transmission information received, the terminal device can learn information such as the paging transmission time and paging transmission mechanism of the network-side device, and then analyze the local data to determine the cause of paging failure. For example, according to the paging transmission time indicated in the paging transmission information, the terminal device can, based on the locally recorded log data, determine whether the terminal device is in an abnormal state, such as a shutdown state, flight mode, out of service area, etc., at the corresponding paging transmission time. If the terminal device is indeed in an abnormal state at the corresponding paging transmission time, the cause of paging failure can be determined to be that the terminal device is in an abnormal state at the paging transmission time. Or, according to the paging transmission mechanism indicated in the paging transmission information, the terminal device can, based on the locally recorded log data, determine the paging reception mechanism of the terminal device and determine whether the paging reception mechanism of the terminal device matches the paging transmission mechanism of the network-side device. If they do not match, the cause of paging failure can be determined to be that the paging reception mechanism of the terminal device does not match the paging transmission mechanism of the network-side device. Optionally, before the terminal device sends the first information to the network-side device, the method further includes: The terminal device receives a paging failure indication sent by the network-side device, where the paging failure indication carries time information, and the paging failure indication is used to indicate that the network-side device has not received a response to the paging corresponding to the time information; The terminal device determines the time range of paging failure according to the time information and determines the first information corresponding to the time range. In the embodiments of the present application, in the case of paging failure or paging loss, the network-side device can notify the terminal device of the failed paging. Exemplarily, the network-side device initiates a paging to the terminal device. If the paging is successful, the terminal device will establish an RRC connection and respond to the paging of the network-side device; if the paging fails, the network-side device will initiate a paging again after a period of time. If the paging fails multiple times, the network-side device will wait for a period of time and then try again. After the paging is successful, the network-side device will notify the terminal device that a paging failure event has occurred before. For example, the network-side device can send a paging failure indication to the terminal device to inform the terminal device that it has not received a response to the previous paging and / or the time information corresponding to the paging failure. Among them, the time information corresponding to the paging failure can be the time period between the first paging failure and the last paging failure of the network-side device, or the occurrence time of the paging failure of the network-side device in the first cell and the occurrence time of the paging failure of the network-side device in the last cell. The paging failure indication can be a paging failure notification short message, an RRC paging failure notification, a NAS paging failure notification, etc. After the terminal device enters the connected state and receives a paging failure indication, it determines the time range of the paging failure according to the time information carried in the paging failure indication. Then, the terminal device determines the first information according to the log data recorded within this time range and sends the first information to the network-side device, so that the network-side device can screen the paging transmission information. In one implementation, the paging transmission information is the paging transmission information within the time range. Optionally, the first information includes at least one of the following: The location information of the terminal device within the time range corresponding to the paging failure; The paging reception mechanism of the terminal device; The radio resource control state in which the terminal device is located; The serving area residence information of the terminal device; The paging identifier of the terminal device; The device attribute information of the terminal device; The first request information, which is used to request the network-side device to provide the overall paging loss rate or loss times of the geographical area (such as the resident cell or TA area) where the terminal device is located within the time range; The second request information, which is used to request the network-side device to provide whether there are other terminal devices with paging failures within the geographical area where the terminal device is located within the time range, and / or, which is used to request the network-side device to provide the device attribute information of other terminal devices with paging failures within the geographical area (such as the resident cell or TA area) where the terminal device is located within the time range. In addition, the first information may further include the time stamp, time period, or corresponding paging moment corresponding to the above information items. Optionally, the location information includes at least one of the following: Resident cell information; Tracking area identifier; RAN-based notification area identifier. The location information of the terminal device may include at least one of the following: the resident cell information of the terminal device, the tracking area (TA) area identifier where the terminal device is located, the RAN-based notification area (RNA) identifier, etc. Among them, the resident cell information may include, but is not limited to, the cell ID, the duration of staying in each cell, etc. The paging reception mechanism may include: whether to listen to PEI or LP-WUS, and if listening to PEI, the PEI packet information, or if listening to LP-WUS, the LP-WUS packet information. The radio resource control (RRC) state of the terminal device may include the RRC_IDLE state or the RRC_inactive state, or simply referred to as the IDLE or Inactive state. Optionally, the service area residence information includes at least one of the following: A first indication for indicating whether the terminal device is not in the service area or the signal coverage area; The time period during which the terminal device is not in the service area or the signal coverage area; The time period during which the terminal device does not monitor the paging occasion; The cell identifier of the last resident cell before the terminal device is not in the service area or the signal coverage area; The cell identifier of the first resident cell when the terminal device returns to the service area or the signal coverage area. It can be understood that if the first information includes at least one of the above service area residence information, the network side device may not send subsequent information to the terminal device, because the terminal device can already determine the reason for paging failure or paging loss based on the above information. The attribute information of the terminal device may include at least one of the paging ID, terminal brand, and terminal model of the terminal device. In the embodiments of the present application, the terminal device may also request the network side device to provide the paging loss rate or the number of paging losses in the geographical area where the terminal device is located during the corresponding time period through the first request information; or, through the second request information, request the network side device to provide whether there are other UEs with paging failure or paging loss in the geographical area where the terminal device is located during the corresponding time period, and / or request the device attribute information such as the terminal brand and terminal model of other UEs with paging failure, so as to further determine whether it is the same brand or the same model as the local device. Optionally, the paging sending information includes at least one of the following: The time when the network side device sends the paging message; The radio resource control state of the terminal device when the network side device records the paging; The discontinuous reception configuration and / or the extended discontinuous reception configuration used by the network side device when paging the terminal device; A second indication for indicating whether the network side device uses a paging optimization mechanism; A third indication for indicating the paging optimization mechanism actually used by the network side device; The time when the cell where the terminal device is located sends the paging; Paging loss time range; Within the paging loss time range, at least one of the paging loss rate or the number of paging losses in the geographical area where the terminal device is located, and / or the device attribute information, paging loss rate, number of paging losses, and statistical time period of other terminal devices with paging losses in the geographical area. It should be noted that the statistical time period of the paging loss rate or the number of paging losses can completely overlap or partially overlap with the time period corresponding to the first request information and / or the second request information sent by the terminal device. The terminal device determines the paging failure reason based on the received paging transmission information. As an example, if the first information includes the location information of the terminal device within the time range corresponding to the paging failure, such as the resident cell, TA area, etc. where the terminal device is located, then the network-side device can, based on this location information, filter out the paging transmission information that occurred in the corresponding area, such as the moments when paging messages were sent in the resident cell, TA area, and send the filtered paging transmission information to the terminal device. Alternatively, if the first information includes the paging identifier of the terminal device, then the paging transmission information sent by the network-side device can include the discontinuous reception configuration and / or the extended discontinuous reception configuration used by the network-side device when paging the terminal device. To save power, the terminal device only listens to its own paging opportunities within the DRX cycle. If the discontinuous reception configuration used by the network-side device when paging the terminal device does not match the paging opportunities listened to by the terminal device, and / or the extended discontinuous reception configuration used by the network-side device does not match the paging opportunities listened to by the terminal device, it can be determined that the reason for the paging failure is that the terminal device did not listen to the corresponding paging opportunities. Alternatively, if the first information includes the paging reception mechanism of the terminal device, then the paging transmission information sent by the network-side device can include a second indication or a third indication. If the paging reception mechanism of the terminal device does not match the actual paging optimization mechanism used by the network-side device, it can be determined that the reason for the paging failure is that the paging reception mechanism of the terminal device does not match the actual paging optimization mechanism used by the network-side device. Alternatively, if the first information includes the RRC state of the terminal device, the paging transmission information can include the RRC state of the terminal device when it was paged as recorded by the network-side device, so that the terminal device can determine whether the RRC state of the terminal device when it was paged as recorded by the network-side device is consistent with the actual RRC state of the terminal device. Alternatively, if the first information includes the service area residence information of the terminal device, the paging transmission information can include the moment when the cell where the terminal device is located sends a paging, or the paging loss time range, so that the terminal device can determine whether the terminal device is not in the service area or not within the signal coverage area when the network-side device pages the terminal device. Alternatively, the first information includes device attribute information or second request information of the terminal device, and the paging transmission information may include device attribute information for paging other lost terminal devices within the geographical area where the terminal device is located, so that the terminal device can determine whether devices of the same brand or the same model have paging failures during the same period. Alternatively, the first information includes first request information, and the paging transmission information may include the paging loss rate or the number of paging losses within the geographical area where the terminal device is located within the time range corresponding to the paging failure, and so on. In one implementation, the paging loss in the embodiments of the present application can be understood as paging failure, the paging failure information can be understood as paging loss information, the paging loss rate can be understood as paging failure rate, the number of losses can be understood as the number of failures, and the time range of paging loss can be understood as the time range of paging failure. Optionally, the paging failure reason includes at least one of the following: The terminal device does not receive paging downlink control information within the time period when paging is sent in the cell to which it belongs; The signal quality of the downlink signal received by the terminal device at the moment corresponding to the paging occasion is less than or equal to a first threshold; The signal quality of the cell synchronization signal block corresponding to the terminal device is less than or equal to a second threshold; At the moment corresponding to the paging occasion, the difference between the signal quality of the physical downlink control channel and the signal quality of the cell synchronization signal block is less than or equal to a third threshold; The difference between the signal quality of the physical downlink shared channel scheduled by the paging occasion and the signal quality of the cell synchronization signal block is less than or equal to a fourth threshold; The terminal device is in an abnormal state; The terminal device does not receive a paging advance indication within a second time period; the second time period includes the time period configured by the network side device for the terminal device to receive the paging advance indication; The terminal device does not receive a low-power wake-up signal within a third time period; the third time period includes the time period configured by the network side device for the terminal device to receive the low-power wake-up signal; The terminal device receives the paging downlink control information within the first time period, but does not receive the physical downlink shared channel scheduled by the downlink control information. Among them, the signal quality of the downlink signal received by the terminal device at the PO moment includes the signal quality of the PDCCH channel corresponding to the PO moment or the signal quality of the PDSCH channel scheduled by the PO. The signal quality of the downlink signal can be reflected by the Reference Signal Receiving Power (RSRP), the Reference Signal Received Quality (RSRQ), the Signal to Interference plus Noise Ratio (SINR), etc. The signal quality of the cell synchronization signal block (SSB) corresponding to the terminal device can be reflected by the RSRP, the RSRQ, etc. The terminal device being in an abnormal state may include, but is not limited to: the terminal device being in the flight mode, powered off, out of service area, etc. Optionally, the method further includes: Step S11: The terminal device establishes a data plane bearer; Step S12: The terminal device sends the first information to the network side device through the data plane bearer. In the embodiment of the present application, the terminal device can establish a data plane bearer for reporting the first information. Optionally, the method further includes: The terminal device sends second information to the network side device. Among them, the second information includes at least one of the following: The reason for paging failure; The paging moment corresponding to the reason for paging failure; The paging reception mechanism of the terminal device; The listening time period corresponding to the paging reception mechanism; The suggestion of the terminal device on the paging configuration of the network side device; The suggestion of the terminal device on the paging sending mechanism of the network side device; The suggestion of the terminal device on the paging sending power of the network side device; The device attribute information of the terminal device. Among them, the paging moment corresponding to the reason for paging failure can be a paging identifier, PF, PO, etc., or one or more time periods corresponding to the reason for paging failure. The paging reception mechanism of the terminal device may include: whether to listen to the PEI or LP-WUS or PEI packet information / LP-WUS packet information, DRX configuration or eDRX configuration, etc. The suggestions of the terminal device for paging configuration may include: DRX / eDRX cycle, and configuration suggestions for paging parameters such as Ns, firstPDCCH-MonitoringOccasionOfPO, nAndPagingFrameOffset, etc. The suggestions of the terminal device for the paging sending mechanism may include: whether to configure PEI, LP-WUS, and how to configure the PEI group / LP-WUS group, etc. Optionally, the terminal device sends second information to the network device, including: Step S21, the terminal device sends the second information to the network device on the uplink shared channel; and / or, Step S22, the terminal device encrypts the second information and sends the encrypted second information ciphertext to the network device. In the embodiment of the present application, when the terminal device reports the second information to the network device, it can be reported anonymously. For example, the terminal device sends the second information on the uplink common signal, and the uplink common channel is shared by all terminal devices (such as SRB0 or the default data plane bearer). Therefore, the network device does not know the identity of the terminal device that sends this information; the default data plane bearer is similar to SRB0 and adopts the default configuration, and there is no need to establish and configure it through signaling. Alternatively, the terminal device can encrypt the second information, such as encrypting it with the public key of the network device, or encrypting it with a pre-agreed key based on the asymmetric algorithm, and only the network device that receives this information can decrypt it, etc. Optionally, the method further includes: The terminal device sends third information to the network device. Wherein, the third information includes at least one of the following: A third indication, which is used to indicate that the terminal device supports the acquisition, caching, or reporting of the first information; The acquisition duration of the first information supported by the terminal device. In the embodiment of the present application, the terminal device can report the paging loss optimization ability by sending third information to the network device. Among them, the paging loss optimization ability includes: whether the terminal device supports operations such as the acquisition, caching, and reporting of the first information, and / or the acquisition duration of the first information supported by the terminal device. It should be noted that the acquisition duration of the first information supported by the terminal device can be the maximum duration that the terminal device can trace based on the received paging failure information and the recorded log data after the terminal device receives the paging failure information sent by the network-side device. When the length between the paging loss moment and the moment when the UE receives the paging failure information sent by the NW is less than the first information acquisition duration, a better tracing effect can be ensured because the UE side still stores the log data of the network parameters (such as cell quality) detected by the UE at the paging loss moment. The acquisition duration can be expressed in hours, minutes, seconds, milliseconds, superframes, frames, subframes, time slots, symbols, the number of DRX cycles, etc. Optionally, the method further includes: The terminal device subscribes to a paging failure notification from the first device and / or the network-side device. Among them, the first device can be the server of the operator. The terminal device can subscribe to a paging failure notification from the operator or the network-side device. The paging failure notification can be a paging failure notification SMS, an RRC paging failure notification, an NAS paging failure notification, etc. In one implementation, the paging failure notification is used to notify the terminal device that paging has failed or the sending moment of the paging for which paging failure has occurred. Exemplarily, the user subscribes to the missed paging SMS notification service with the operator. Users who have subscribed to this service will receive an SMS notification when the paging called to the terminal device (such as a mobile phone, a personal computer, etc.) held by them fails to be delivered. The relevant SMS notification will carry the paging sending moment. Or, the terminal device subscribes to a paging failure notification from the network-side device. The terminal device that has subscribed to the paging failure notification will receive the information of the undelivered paging, such as the paging sending moment, after accessing the network or when the paging is reachable. Optionally, the method further includes: The terminal device sends a data request to the network-side device, and the data request includes at least one of the following: A paging failure event; A first threshold time, which is used to indicate the timeliness requirement for the network-side device to send the paging failure information corresponding to the paging failure event. In the embodiments of the present application, the terminal device can request the network-side device to provide the paging failure information corresponding to the paging failure event by sending a data request to the network-side device. Further, the terminal device can carry the first threshold time in the data request to require the network-side device to send the paging failure information within the first threshold time of the paging failure, so as to avoid being unable to trace the cause of the paging failure due to the log data locally recorded by the terminal device being overwritten. Optionally, the paging failure event includes at least one of the following: A paging failure occurs for the terminal device; There are N consecutive paging failures for the terminal device; N is a positive integer greater than 1; There are M paging failures for the terminal device within a configured time window; M is a positive integer. Optionally, the method further includes: The terminal device receives paging failure information sent by the network side device. In one implementation, the paging failure information is the paging failure information sent by the network side device within a first threshold time from the occurrence of the paging failure. In the embodiments of the present application, the network side device needs to send paging failure information to the terminal device within a first threshold time from the occurrence of the paging failure, so that the terminal device can trace the cause of the paging failure. Optionally, the paging failure information includes at least one of the following: The cell identifier of the paging failure cell; The paging failure moment; The cause of the paging failure. Optionally, the terminal device determines the time range of the paging failure according to the time information, and determines the first information corresponding to the time range, including: The terminal device determines the time range of the paging failure according to the time information; The terminal device filters out the data corresponding to the time range from the recorded log data, and generates the first information according to the filtered data. In one implementation, the network side device needs to send a paging failure indication to the terminal device within a first threshold time from the occurrence of the paging failure. After receiving the paging failure indication, the terminal device determines the time range of the paging failure according to the time information carried in the paging failure indication, filters out the data corresponding to the time range from the locally recorded log data, generates the first information and sends it to the network side device in time, so as to prevent these data from being overwritten by subsequent logs. In summary, the embodiments of the present application provide a method for determining paging failure. The terminal device sends the first information to the network side device; the network side device filters out the paging transmission information based on the received first information and sends it to the terminal device. The paging transmission information indicates the paging transmission time and paging transmission mechanism of the network side device. The terminal device can determine the cause of the paging failure based on the received paging transmission information. In the embodiments of the present application, the terminal device and the network side device can cooperate to confirm the specific cause of the paging failure, so as to improve the paging failure cause, which is beneficial to optimizing the paging performance. The embodiments of the present application provide a method for determining paging failure. Referring to FIG. 6, a flowchart of a method for determining paging failure provided by the embodiments of the present application is shown. This method is applied to the first device. As shown in FIG. 6, this method may specifically include: Step 201: The first device subscribes to the desensitized paging failure information from the network device. In the embodiments of the present application, the first device may be a server of an operator or a third-party server, such as a server of a terminal manufacturer. The first device may subscribe to the desensitized paging failure information from the network device of the operator. For example, based on user complaints, the operator or the terminal manufacturer determines the geographical area where paging loss occurs (such as GNSS coordinates, Cell ID, street name, etc.), and subscribes to the paging failure information of the corresponding area from the network device through the first device. Optionally, the method further includes: The first device receives the paging failure information sent by the network device. Wherein, the paging failure information includes at least one of the following: The cell identifier of the paging failure cell; The paging failure time; The paging failure reason. After the network device determines one or more of the data such as the ID of the missed paging cell, the missed paging time, and the potential missed paging reason, it provides the desensitized missed paging statistical data matching the cell ID to the first device. It can be understood that if the terminal device reports the paging failure reason in an anonymous reporting form, the network device may omit the data desensitization step and directly forward the paging failure reason reported by the terminal device to the corresponding first device, or send the paging failure reason reported by the terminal device to the first device after statistical processing. Optionally, the network device notifies the first device that the collected information is reported based on an anonymous method or a real-name method. In summary, in the method for determining paging failure provided by the embodiments of the present application, the first device can determine the paging failure reason by subscribing to the desensitized paging failure information from the network device. The embodiments of the present application provide a method for determining paging failure. Referring to FIG. 7, a flowchart of a method for determining paging failure provided by the embodiments of the present application is shown. This method is applied to the network device. As shown in FIG. 7, this method may specifically include: Step 301: The network device receives the first information sent by the terminal device; Step 302: The network device filters the paging transmission information according to the first information; the paging transmission information is used to indicate at least one of the paging transmission time and the paging transmission mechanism of the network device; Step 303: The network device sends the paging transmission information to the terminal device. In an embodiment of the present application, the network - side device filters out corresponding paging transmission information according to the received first information, and timely sends the filtered paging transmission information to the terminal device, so that the terminal device can determine the paging failure reason based on the received paging transmission information. Optionally, before the network - side device receives the first information sent by the terminal device, the method further includes: When the network - side device fails to page the terminal device, it sends a paging failure indication to the terminal device; the paging failure indication carries time information, and the paging failure indication is used to indicate that the network - side device has not received a response to the paging corresponding to the time information. In an embodiment of the present application, when the network - side device fails to page or loses a page, it can notify the terminal device of the failed paging. Exemplarily, the network - side device initiates a paging to the terminal device. If the paging is successful, the terminal device will establish an RRC connection and respond to the paging of the network - side device; if the paging fails, the network - side device will initiate a paging again after a period of time. If the paging fails multiple times, the network - side device will wait for a period of time and then try again. After the paging is successful, the network - side device will notify the terminal device that a paging failure event has occurred before. For example, the network - side device can send a paging failure indication to the terminal device, informing the terminal device of the previous failed paging and the time information corresponding to the paging failure. Among them, the time information corresponding to the paging failure can be the time period between the first paging failure and the last paging failure of the network - side device, or the occurrence time of the paging failure of the network - side device in the first cell and the occurrence time of the paging failure of the network - side device in the last cell. After the terminal device enters the connected state and receives the paging failure indication, it determines the time range of the paging failure according to the time information carried in the paging failure indication. Then, according to the log data recorded within this time range, it determines the first information and sends the first information to the network - side device. Optionally, the first information includes at least one of the following: The location information of the terminal device within the time range corresponding to the paging failure; The paging reception mechanism of the terminal device; The radio resource control state in which the terminal device is located; The serving area residence information of the terminal device; The paging identifier of the terminal device; The device attribute information of the terminal device; A first request information, which is used to request the network - side device to provide the paging loss rate or the number of losses of the geographical area where the terminal device is located within the time range; A second request message, which is used to request the network side device to provide whether there is any other terminal device with a paging failure in the geographical area where the terminal device is located within the time range, and / or is used to request the network side device to provide the device attribute information of other terminal devices with paging failures in the geographical area where the terminal device is located within the time range. Optionally, the paging transmission information includes at least one of the following: The time when the network side device sends a paging message; The radio resource control state of the terminal device when it is paged, recorded by the network side device; The discontinuous reception configuration and / or extended discontinuous reception configuration used by the network side device to page the terminal device; A second indication, which is used to indicate whether the network side device adopts a paging optimization mechanism; A third indication, which is used to indicate the paging optimization mechanism actually adopted by the network side device; The time when the cell where the terminal device is located sends a paging; The time range of paging loss; Within the time range of paging loss, the paging loss rate or the number of paging losses in the geographical area where the terminal device is located, and / or at least one of the device attribute information, paging loss rate, number of paging losses, and statistical time period of other terminal devices with paging losses in the geographical area. It should be noted that the statistical time period of the paging loss rate or the number of paging losses may completely overlap or partially overlap with the time period corresponding to the first request message and / or the second request message sent by the terminal device. The terminal device determines the cause of paging failure according to the received paging transmission information. As an example, if the first information contains the location information of the terminal device within the time range corresponding to the paging failure, such as the resident cell, TA area, etc. where the terminal device is located, then the network side device can, according to this location information, filter out the paging transmission information that occurs in the corresponding area, such as the time when the paging message is sent in the resident cell or TA area, and send the filtered paging transmission information to the terminal device. Alternatively, if the first piece of information contains the paging identifier of the terminal device, the paging transmission information sent by the network-side device may include the discontinuous reception configuration and / or the extended discontinuous reception configuration used by the network-side device when paging the terminal device. To save power, the terminal device only listens for its own paging occasions within the DRX cycle. If the discontinuous reception configuration used by the network-side device when paging the terminal device does not match the paging occasions listened for by the terminal device, and / or the extended discontinuous reception configuration used by the network-side device does not match the paging occasions listened for by the terminal device, it can be determined that the reason for the paging failure is that the terminal device did not listen for the corresponding paging occasions. Alternatively, if the first piece of information contains the paging reception mechanism of the terminal device, the paging transmission information sent by the network-side device may include a second indication or a third indication. If the paging reception mechanism of the terminal device does not match the paging optimization mechanism actually used by the network-side device, it can be determined that the reason for the paging failure is that the paging reception mechanism of the terminal device does not match the paging optimization mechanism actually used by the network-side device. Alternatively, if the first piece of information contains the RRC state of the terminal device, the paging transmission information may include the RRC state of the terminal device when it was paged as recorded by the network-side device, so that the terminal device can determine whether the RRC state of the terminal device when it was paged as recorded by the network-side device is consistent with the actual RRC state of the terminal device. Alternatively, if the first piece of information contains the service area residence information of the terminal device, the paging transmission information may include the time when the cell where the terminal device is located sends a paging, or the time range of paging loss, so that the terminal device can determine whether the terminal device is not in the service area or within the signal coverage area when the network-side device pages the terminal device. Alternatively, if the first piece of information contains the device attribute information or the second request information of the terminal device, the paging transmission information may include the device attribute information of other terminal devices with paging loss within the geographical area where the terminal device is located, so that the terminal device can determine whether devices of the same brand or the same model have paging failures during the same period. Alternatively, if the first piece of information contains the first request information, the paging transmission information may include the paging loss rate or the number of paging losses in the geographical area where the terminal device is located within the time range corresponding to the paging failure, and so on. Optionally, the method further includes: The network-side device sends paging failure information to a first device. Wherein, the paging failure information includes at least one of the following: The cell identifier of the cell with paging failure; The paging failure moment; The reason for the paging failure. The first device may be the operator's server or a third-party server, such as the server of the terminal manufacturer. In the embodiments of the present application, the first device may subscribe to the desensitized paging failure information from the network-side device of the operator. After the network-side device determines data such as the ID of the missed paging cell, the missed paging time, and the potential missed paging reason, it provides the desensitized paging statistics data matching the cell ID to the first device. Optionally, the method further includes: The network-side device receives a data request sent by the terminal device, and the data request includes at least one of the following: A paging failure event; A first threshold time, which is used to indicate the timeliness requirement for the network-side device to send the paging failure information corresponding to the paging failure event. In the embodiments of the present application, the terminal device may request the network-side device to provide the paging failure information corresponding to the paging failure event by sending a data request to the network-side device. Further, the terminal device may carry the first threshold time in the data request, so as to require the network-side device to send the paging failure information within the first threshold time of the paging failure, and avoid the log data locally recorded by the terminal device being overwritten and the reason for the paging failure cannot be traced. Optionally, the method further includes: The network-side device sends the paging failure information to the terminal device within the first threshold time of the paging failure for the terminal device. In the embodiments of the present application, the network-side device needs to send the paging failure information to the terminal device within the first threshold time from the occurrence of the paging failure, so that the terminal device can trace the reason for the paging failure. Optionally, the paging failure event includes at least one of the following: A paging failure occurs for the terminal device; N consecutive paging failures occur for the terminal device; N is a positive integer greater than 1; M paging failures occur for the terminal device within the configured time window; M is a positive integer. In summary, the embodiments of the present application provide a method for determining paging failure. After the network-side device receives the first information within the time range of the paging failure sent by the terminal device, it filters the paging sending information within this time range according to the first information and sends it to the terminal device. The paging sending information is used to inform the terminal device of information such as the paging sending time and the paging sending mechanism of the network-side device, so that the terminal device can determine the reason for the paging failure according to the paging sending information. In the embodiments of the present application, the terminal device and the network-side device can cooperate to confirm the specific reason for the paging failure, so as to improve the paging failure reason, which is beneficial to optimizing the paging performance.
