[0042] In addition, to facilitate understanding of this solution, a brief introduction to the technical terms involved in the embodiments of this application is provided as follows.

[0043] 1. Paging function

[0044] The paging function requires the terminal to receive information from the network device at a specific location, such as a paging frame (PF) or paging occasion (PO). A PO may contain a subframe containing the terminal's paging message. A PF is the radio frame in which the user sends a paging message and may contain one or more POs.

[0045] In one implementation, when discontinuous reception (DRX) is enabled, in order to save power, the terminal only monitors its own POs within the DRX cycle.

[0046] 2. Paging Early Indication (PEI)

[0047] For terminals in the idle state, synchronization signal block (SSB) measurements and paging reception are required during each paging cycle. Paging reception involves the terminal monitoring the paging physical downlink control channel (PDCCH) on its associated PO, and then receiving the paging physical downlink shared channel (PDSCH) after monitoring the paging PDCCH.

[0048] Multiple terminals can be associated with one PO group. Therefore, a terminal may be mistakenly awakened to monitor the paging PDCCH and paging PDSCH due to paging of other terminals in the same group. The terminal will not go back to sleep until it confirms that the paging PDSCH does not have the terminal identification (ID) of the terminal. Therefore, since the terminal detects the paging PDCCH or paging PDSCH in each paging cycle, and since there are multiple associated terminals in a PO group, the terminal may be mistakenly awakened, resulting in unnecessary monitoring power consumption of the terminal.

[0049] To reduce terminal power consumption, the R17 standard further introduces PDCCH-based PEI information, meaning that the terminal receives PEI information before receiving the paging PDCCH. The terminal then determines whether it needs to monitor subsequent paging PDCCHs based on the content indicated in the paging advance indicator PEI downlink control information (DCI). The advantage is that the terminal can determine in advance whether it needs to receive the paging PDCCH based on the PEI. If the PEI indicates that the terminal does not receive the paging PDCCH, the terminal does not need to detect one or more SSBs between the PEI and the PO, thereby saving power.

[0050] In addition, PEI also has the function of further grouping and indicating the terminal groups of a PO. For example, PEI is associated with and indicates a PO. PEI carries 8 bits of information for further terminal grouping indication of the PO. Each bit corresponds to a subgroup, which means that a total of 8 subgroups can be indicated for early paging. Therefore, the terminals associated with a PO are further divided into 8 subgroups, and PEI indication is performed for each subgroup. This can reduce the probability of false wake-up of the terminal, thereby reducing the power consumption of the terminal's paging monitoring.

[0051] 3. Low power wake up signal (LP-WUS)

[0052] LP-WUR can also be called an almost zero power wake up radio (AZP-WUR). The basic working principle of LP-WUR is that the terminal includes a first module and a second module. The first module is a main communication module (also referred to as a main receiver in this application), which is used for sending and receiving mobile communication data. The second module is a low-power receiving module (also referred to as a low-power wake-up receiving module) (also referred to as a WUR receiver in this application), which is used to receive a wake-up signal. In the energy-saving state, the terminal turns on the low-power receiving module to monitor LP-WUS and turns off the main communication module. When downlink data arrives, the network side device will send a wake-up signal to the terminal. After the terminal monitors the wake-up signal through the low-power receiving module, it triggers the main communication module from off to on after a series of judgments, 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 turned on continuously or intermittently, and can receive a low-power wake-up signal when it is turned on.

[0053] To reduce terminal reception activity in standby mode, effectively shutting down the RF and baseband (MODEM) modules, significantly reducing power consumption during communication reception, a near-zero-power receiver is introduced into the terminal's receiving module. This near-zero-power receiver eliminates the complex signal detection (such as amplification, filtering, and quantization) required by the RF module and the signal processing required by the MODEM, relying solely on passive matched filtering and low-power signal processing.

[0054] On the network side, by triggering a wake-up signal on demand, the near-zero-power receiver can be activated to receive the activation notification, thereby triggering a series of processes within the terminal, such as turning on the RF transceiver and baseband processing modules.

[0055] This wake-up signal is typically a simple on-off keying signal. The time domain pattern of the on-off keying signal is shown in Figure 1b. The receiver can detect the wake-up notification through simple energy detection and, if necessary, subsequent sequence detection and recognition. Furthermore, while the terminal activates the low-power wake-up receiver to receive the wake-up signal, the main receiver module can maintain a low power consumption level, thereby saving power by receiving the wake-up signal.

[0056] The low-power wake-up signal can carry a small payload, such as 10 bits of information.

[0057] Receiving the low-power wake-up signal can be applied to a terminal in a Radio Resource Control (RRC)_idle or RRC_inactive state, or to a terminal in an RRC_connected state, thereby achieving energy saving for the terminal.

[0058] For example, for a terminal in RRC_idle or RRC_inactive state, the terminal may first monitor the LP-WUS signal and determine whether to monitor the PEI or the Paging DCI.

[0059] Based on this, the technical solutions provided by the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0060] As shown in FIG2 , a flowchart of a paging method 200 provided in an exemplary embodiment of the present application is shown. The method 200 may be, but is not limited to, executed by a terminal, specifically by hardware or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0061] S210: The terminal receives first information from a network-side device.

[0062] The first information is used to indicate information related to paging message transmission, so that the terminal can analyze the cause of paging failure based on the information related to the paging message transmission, thereby optimizing paging performance. It is understood that the paging failure mentioned in the embodiments of the present application can also be understood as paging loss, etc., which is not limited here.

[0063] In an optional implementation, the first information may include but is not limited to at least one item from 11) to 14).

[0064] 11) Information of a first object related to the paging message transmission.

[0065] Among them, the information of the first object may include but is not limited to at least one of the identifier of the access network notification area (RAN-based Notification Area, RNA) where the network side device sends the paging message, the tracking area (TA) identifier, the gNB identifier, the cell identifier, the terminal identifier, the paging initiation time, the paging identifier, the DRX configuration, and the extended DRX (eDRX) configuration.

[0066] The paging initiation time may be, but is not limited to, PF, PO, PDCCH monitoring occasion, paging time period, etc.

[0067] It is worth noting that the terminal may determine the cause of the paging failure based on the information of the first object in multiple ways. For example, assuming that the information of the first object is a RAN identifier, the terminal may determine whether it is in the RAN area corresponding to the RAN identifier or whether the downlink signal quality of the RAN area corresponding to the RAN identifier meets the requirements. If the terminal determines that it is not in the RAN area corresponding to the RAN identifier or that the downlink signal quality of the RAN area corresponding to the RAN identifier does not meet the requirements, the paging failure cause may be determined to include at least the terminal determining that it is not in the RAN area corresponding to the RAN identifier or that the downlink signal quality of the RAN area corresponding to the RAN identifier does not meet the requirements.

[0068] For another example, assuming that the information of the first object is the terminal identifier, the terminal can determine whether the terminal identifier is consistent with its own terminal identifier. If not, it can be determined that the cause of the paging failure includes at least terminal identifier inconsistency. In other words, the terminal identifier used by the network-side device when transmitting the paging message is inconsistent with the identifier of the terminal to be paged, resulting in an erroneous paging message transmission. Subsequently, the network-side device did not receive a paging response sent from the terminal to be paged, i.e., a paging failure.

[0069] For example, assuming that the information of the first object is the paging initiation time, the terminal can determine whether the paging message is received within the paging initiation time, etc. If the terminal does not receive the paging message within the paging initiation time, it can be determined that the reason for the paging failure at least includes the inconsistency between the paging initiation time and the time when the terminal receives the paging message.

[0070] It is worth noting that the process of determining the cause of paging failure based on information of other first objects is similar to the aforementioned RAN identifier, terminal identifier, and paging initiation time, and will not be repeated here.

[0071] 12) Whether a paging optimization mechanism is applied when sending the paging message. The paging optimization mechanism may include but is not limited to PEI, LP-WUS, etc. The description of PEI and LP-WUS is not repeated here.

[0072] It is worth noting that when the terminal determines the cause of paging failure based on "whether the paging optimization mechanism is applied when sending the paging message", its implementation process may include but is not limited to: assuming that the paging optimization mechanism, such as PEI, is applied when sending the paging message, then the terminal needs to determine whether it receives PEI. If it does not receive PEI, it can be determined that the cause of the paging failure is that the terminal did not receive PEI.

[0073] 13) When sending the paging message, the network side device expects or desires the RRC state of the terminal, such as RRC-idle state, RRC-inactive state, etc.

[0074] It is worth noting that when the terminal determines the cause of paging failure based on "the RRC state of the terminal expected or desired by the network side device when sending the paging message", its implementation process may include but is not limited to: assuming that when sending the paging message, the RRC state of the terminal expected or desired by the network side device is the RRC-idle state, then the terminal can determine whether it is in the RRC-idle state when receiving the paging message. If it is not in the RRC-idle state, then it can be determined that the cause of the paging failure at least includes that the RRC state of the terminal is inconsistent with the RRC state of the terminal expected or desired by the network side device.

[0075] 14) The paging sending mechanism corresponding to the paging message, wherein the paging sending mechanism may include but is not limited to a RAN paging mechanism, a core network paging mechanism, etc., which are not limited here.

[0076] It is worth noting that when the terminal determines the cause of the paging failure based on the "paging sending mechanism corresponding to the paging message", its implementation process may include but is not limited to: assuming that the paging sending mechanism is a RAN paging mechanism, then the terminal may determine whether the RAN paging mechanism is enabled for itself. If not, determining that the cause of the paging failure includes at least that the RAN paging mechanism is not enabled for the terminal.

[0077] In this embodiment, the first information may be autonomously sent by the network-side device to the terminal, or may be requested or subscribed by the terminal to the network-side device, etc., which is not limited here.

[0078] It is worth noting that the network side devices mentioned in the embodiments of the present application may be, but are not limited to, RAN nodes or core network nodes. The RAN nodes may be, but are not limited to, gNB nodes, etc., and the core network nodes may be, but are not limited to, AMF, UDM, etc.

[0079] Correspondingly, the paging message may be initiated by a RAN node or a core network node, and is not limited here.

[0080] S220: Determine a paging failure reason based on the first information.

[0081] In this embodiment, when the terminal determines the cause of the paging failure, in addition to the first information, it may also determine the cause of the paging failure in combination with the first information and the relevant information collected independently within the time range of the paging failure, etc., and there is no limitation here. Among them, the relevant information within the time range of the paging failure may be, but is not limited to, the relevant information of the terminal within the time range of the paging failure, such as the moving path of the terminal, the cell information of the terminal, the downlink signal quality, the paging reception mechanism adopted by the terminal, the RRC state of the terminal, whether the terminal is in the service area, the last resident cell when the terminal is not in the service area, the first resident cell when the terminal returns to the service area, etc. It can be understood that the "service area" mentioned in the embodiment of the present application is also understood to be the network coverage area, etc.

[0082] In an optional implementation, the reasons for the paging failure may include but are not limited to the downlink signal quality not meeting the requirements, the terminal being in an abnormal state, the terminal not receiving the paging DCI or PEI or LP-WUS at the scheduled time, and the terminal receiving the paging DCI at the scheduled time but not receiving at least one of the PDSCHs scheduled by the paging DCI.

[0083] Among them, "downlink signal quality does not meet the requirements" can also be understood as poor downlink signal quality, such as the signal quality of the PDCCH received by the terminal on the PO is lower than a predetermined value, the signal quality of the PDSCH scheduled on the PO is lower than a predetermined value, etc., which is not limited here. The downlink signal quality can be represented by, but not limited to, reference signal received power (RSRP), reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR), etc.

[0084] “The terminal is in an abnormal state” may include but is not limited to the terminal being in flight mode, the terminal being powered off, the terminal being out of service area, etc.

[0085] It is understood that after determining the paging failure cause, the terminal can independently optimize the paging performance based on the paging failure cause, or notify the network side device and have it optimize the paging performance based on the paging failure cause, etc., without limitation herein. It is worth noting that the "paging performance optimization" mentioned in the embodiments of this application can also be referred to as paging failure performance optimization, etc.

[0086] Of course, no matter whether the paging performance optimization is performed by the terminal or the network side device, both have a consistent understanding of the performance optimization result.

[0087] In this embodiment, the terminal receives first information indicating information related to paging message transmission from a network side device, and determines the cause of paging failure based on the first information, thereby realizing the determination of the cause of paging failure, and then realizing the optimization of paging performance based on the cause of paging failure, improving the paging performance, and ensuring the reliable reception and sending of subsequent paging messages.

[0088] As shown in Figure 3, a flow chart of a paging method 300 provided in an exemplary embodiment of the present application is provided. The method 300 may be, but is not limited to, executed by a terminal, and specifically may be executed by hardware or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.

[0089] S310: The terminal sends third information or fourth information to the network side device.

[0090] Among them, the third information is used to subscribe to paging failure event notifications, and the fourth information is used to indicate the capabilities supported by the terminal and related to paging failure optimization, so that when a paging failure event occurs, the network side device can send subsequent first information to the terminal based on the paging failure events subscribed by the terminal and the paging failure optimization capabilities supported by the terminal, that is, information related to paging message transmission, for analysis and determination of the cause of the paging failure.

[0091] The aforementioned “paging failure event notification” means that after a paging failure event occurs, the network side device needs to feed back a notification to the terminal to inform the terminal that a paging failure or a paging failure event has occurred.

[0092] In an optional implementation, the paging failure event may include but is not limited to any one of the following 21)-23).

[0093] 21) Paging failure occurs for the terminal.

[0094] 22) N consecutive paging failures occur for the terminal; wherein N is an integer greater than or equal to 1.

[0095] 23) Paging failures occur M times for the terminal within a predetermined time window, where M is an integer greater than or equal to 1, and the predetermined time window may be configured by a protocol or other means.

[0096] That is, if the terminal subscribes to the paging failure event notification through the third information, then the network-side device needs to record the paging failure information. For example, when a paging failure occurs for the terminal, or when N consecutive paging failures occur for the terminal, or when M paging failures occur for the terminal within a predetermined time window, the network-side device needs to record the paging failure information.

[0097] In an optional embodiment, the paging failure information recorded by the network side device may include but is not limited to the information related to the paging message transmission mentioned in the embodiments of the present application, such as information about the first object related to the paging message transmission, whether the paging optimization mechanism is applied when sending the paging message, the RRC status of the terminal expected by the network side device when sending the paging message, the paging sending mechanism corresponding to the paging message, etc.

[0098] Based on this, in some embodiments, the manner in which the terminal sends the third information to the network-side device may include at least one of the following manners 1 and 2, thereby improving the transmission flexibility of the third information.

[0099] Method 1: The terminal sends the third information to the network-side device during the registration process. The registration process may be, but is not limited to, when the terminal registers with the AMF, the AMF obtains the terminal's subscription information from the UDM, and the subscription information includes the third information, i.e., the paging failure event notification to which the terminal needs to subscribe.

[0100] Mode 2: the terminal sends the third information to the network side device when in the RRC connected state, that is, the third information is sent by the terminal to the network side device when in the RRC connected state.

[0101] In addition, in the case where the fourth information is used to indicate a capability supported by the terminal and related to paging failure optimization, the network-side device may determine whether to provide the first information to the terminal. For example, if the terminal supports the paging failure optimization capability, the first information may be sent to the terminal.

[0102] In an optional implementation, the fourth information may include but is not limited to at least one of the following 31)-35).

[0103] 31) The terminal supports a first capability, where the first capability is the ability to optimize paging performance based on information related to paging message transmission or a paging failure cause provided by the network-side device. That is, the terminal is capable of optimizing paging performance based on information related to paging message transmission or a paging failure cause provided by the network-side device. The information related to paging message transmission can be understood as the aforementioned first information and is not further described here.

[0104] 32) The terminal supports the collection and caching of fifth information, where the fifth information is used to indicate relevant information when the terminal receives a paging message. Optionally, the fifth information can be used by the terminal to autonomously determine the cause of a paging failure, optimize paging failure performance, etc. in combination with the first information sent by the network-side device. Alternatively, the fifth information can also be used by the network-side device to determine the cause of a paging failure, optimize paging failure performance, etc., without limitation herein.

[0105] In an optional implementation, the fifth information includes at least one of the following 321)-327).

[0106] 321) seventh information, wherein the seventh information includes at least one of the mobile path of the terminal, the cell information where the terminal resides, the downlink signal quality, the paging reception mechanism adopted by the terminal, and the RRC state of the terminal.

[0107] The moving path of the terminal may be, but is not limited to, the latitude, longitude, altitude, etc. of multiple points on the moving path of the terminal.

[0108] The information of the cell where the terminal resides may be, but is not limited to, the length of time the terminal resides in each cell, the time period of the residency, the ID of the resided cell, etc.

[0109] The downlink signal quality may include but is not limited to RSRP, RSRQ, SINR, etc.

[0110] The paging reception mechanism adopted by the terminal may include but is not limited to whether the terminal monitors PEI or LP-WUS, PEI group information, LP-WUS group information, etc.

[0111] The RRC state of the terminal may include but is not limited to whether the terminal is in an RRC-idle state or an RRC-inactive state.

[0112] 322) Time information corresponding to the seventh information. For example, if the seventh information is the moving path of the terminal, then the time information may be, but is not limited to, a timestamp, time period, or paging time corresponding to the moving path of the terminal.

[0113] Similarly, when the seventh information is other information, it is similar to the moving path of the terminal described above and will not be repeated here.

[0114] 323) Whether the terminal is in the service area.

[0115] 324) The time when the terminal is not in the service area.

[0116] 325) The last cell where the terminal resided before being out of the service area.

[0117] 326) The first resident cell when the terminal returns to the service area.

[0118] 327) The time during which the terminal does not receive the paging message.

[0119] 33) The acquisition duration of the fifth information supported by the terminal, wherein the acquisition duration can be expressed in hours, minutes, seconds, milliseconds, superframes, frames, subframes, time slots, symbols, number of DRX cycles, etc.

[0120] 34) The terminal supports a second capability, which is the ability to determine the cause of paging failure based on information related to paging message transmission provided by the network-side device. That is, the terminal is capable of determining the cause of paging failure based on the information related to paging message transmission provided by the network-side device, so that the terminal or the network-side device can optimize paging performance based on the cause of paging failure. The information related to paging message transmission can be understood as the first information mentioned above and will not be repeated here.

[0121] 35) The terminal supports a third capability, which is the capability to report the paging failure cause, that is, the terminal has the ability to report the paging failure cause determined independently, so that the network side device can optimize the paging performance according to the paging failure cause.

[0122] Optionally, after receiving the fourth information, the network-side device may determine a subsequent paging performance optimization process based on the fourth information. For example, if the fourth information includes that the terminal supports the first capability, the network-side device may send the first information to the terminal to determine the cause of the paging failure, optimize the paging performance, etc.; for another example, if the terminal supports the collection and caching of the fifth information, the network-side device may request the terminal to report the fifth information, so as to determine the cause of the paging failure, optimize the paging performance, etc. based on the fifth information, etc., etc., etc., without limitation herein.

[0123] It is worth noting that there is no restriction on the order of sending the aforementioned third information and fourth information. For example, the terminal can send the third information and the fourth information at the same time, or send the third information first and then the fourth information, or send the fourth information first and then the fourth information, etc.

[0124] In addition, in this embodiment, the reception time of the first information is later than the sending time of the third information or the fourth information; that is, the network side device sends the first information to the terminal based on the received third information or fourth information.

[0125] S320: The terminal receives first information from the network-side device.

[0126] The first information is used to indicate information related to paging message transmission.

[0127] S330: Determine the cause of the paging failure according to the first information.

[0128] It is understood that the implementation process of steps S320 and S330 can refer to the relevant description in the aforementioned method embodiment 200. Of course, in addition to this, as an optional implementation, when determining the cause of the paging failure, the terminal may determine the cause of the paging failure based on not only the first information sent by the network-side device but also the fifth information collected or cached by the terminal. That is, the terminal may determine the cause of the paging failure based on the first information and the fifth information.

[0129] Based on this, after determining the paging failure cause, the terminal can autonomously optimize the paging performance according to the paging failure cause, such as modifying the paging configuration, modifying the terminal status, etc., to ensure reliable reception of subsequent paging messages.

[0130] Alternatively, the terminal may also send a second message to the network side device so that the network side device optimizes the paging performance according to information such as the paging failure cause indicated by the second message, such as modifying the paging configuration, etc., to ensure reliable reception of subsequent paging messages.

[0131] In an optional implementation, the second information may include but is not limited to at least one of the following 41)-47).

[0132] 41) The reason for the paging failure.

[0133] Among them, the reasons for the paging failure may include but are not limited to the downlink signal quality not meeting the requirements, the terminal being in an abnormal state, the terminal not receiving the paging DCI or PEI or LP-WUS at the scheduled time, and the terminal receiving the paging DCI at the scheduled time but not receiving at least one of the PDSCHs scheduled by the paging DCI.

[0134] Among them, "downlink signal quality does not meet the requirements" can also be understood as poor downlink signal quality, such as the signal quality of PDCCH received by the terminal on PO is lower than the predetermined value, the signal quality of PDSCH scheduled on PO is lower than the predetermined value, etc., which is not restricted here.

[0135] “The terminal is in an abnormal state” may include but is not limited to the terminal being in flight mode, the terminal being powered off, the terminal being out of service area, etc.

[0136] 42) The time of occurrence of the paging failure event corresponding to the paging failure cause, for example, the paging time or paging time period corresponding to the paging failure event, where the paging time may be, but is not limited to, a paging identifier, PO, PF, etc.

[0137] 43) The paging reception mechanism used by the terminal. For example, when paging fails, whether the terminal monitors PEI or LP-WUS, PEI grouping information of the PEI monitored by the terminal, LP-WUS grouping information of the LP-WUS monitored by the terminal, DRX configuration or eDRX configuration used by the terminal, etc.

[0138] 44) The occurrence time of the paging failure event corresponding to the paging reception mechanism adopted by the terminal.

[0139] 45) The terminal's suggestion for paging configuration information. For example, the terminal may recommend paging parameters such as the DRX cycle, eDRX cycle, number of POs included in a PF, first PDCCH-Monitoring Occasion of PO, and Paging Frame Offset based on the paging failure cause.

[0140] 46) The terminal's suggestion on the paging transmission mechanism, for example, the terminal's suggestion on whether to configure PEI, whether to configure LP-WUS, how to configure PEI grouping, how to configure LP-WUS grouping, etc. based on the paging failure cause.

[0141] 47) The terminal's suggestion on the paging transmission power, for example, the terminal's suggestion on whether to increase the paging transmission power based on the paging failure cause.

[0142] Of course, in addition to the aforementioned determination of the paging failure cause by the terminal, as an optional implementation method, the network side device can also independently determine the paging failure cause, optimize the paging performance, etc.

[0143] For example, the network-side device may also send a sixth message to the terminal to indicate a paging loss time range; correspondingly, the terminal receives the sixth message sent by the network-side device and sends the fifth message within the paging loss time range to the network-side device, so that the network-side device can determine the cause of the paging failure based on the received fifth message and the autonomously determined first message, and then optimize the paging performance based on the determined paging failure cause to ensure the reliability of subsequent paging messages. The "paging loss time range" can be understood as a time range within which the network-side device sent a paging message but did not receive a paging response from the terminal.

[0144] Optionally, when the network-side device sends the sixth information to the terminal, it may independently determine the timing of sending it, or it may send it based on the third information or fourth information received from the terminal. In the case of sending it based on the third information or fourth information received from the terminal, it can be understood that, for the terminal, the reception time of the sixth information is later than the sending time of the third information or the fourth information.

[0145] In an optional implementation manner, the sixth information may be sent to the terminal via a paging message, or may be sent to the terminal via dedicated signaling, which is not limited here.

[0146] It is worth noting that if the network side device determines the cause of the paging failure based on the fifth information and the first information, then when the terminal sends the fifth information to the network side device, for the case where the fifth information includes the moving path of the terminal and the cell information where the terminal resides, it can report the actual or real moving path and the resident cell information at the same time as reporting the non-actual or real moving path and resident cell information, so as to avoid exposing the privacy of the terminal and ensure communication security.

[0147] That is to say, when the terminal reports the fifth information, the moving path of the terminal may include the actual moving path of the terminal and the non-actual moving path; or, the cell information where the terminal resides includes the cell information where the terminal actually resides and the cell information where the terminal does not actually reside, such as allowing the terminal to report in the fifth information that the terminal resides in multiple cells at the same time point and has multiple moving paths, etc.

[0148] In addition, in the case where the network-side device autonomously determines the cause of the paging failure based on the fifth information and the first information, the terminal may also determine the cause of the paging failure based on the first information sent by the network-side device and the autonomously collected fifth information. That is, in the present application, only the terminal or the network-side device may determine the cause of the paging failure and perform paging performance optimization, or both may determine the cause of the paging failure and perform paging performance optimization, without limitation herein.

[0149] Of course, no matter which party determines the paging failure cause, it can send the paging failure cause to the other party after determining it, thereby ensuring consistency in their understanding of the paging failure cause and further ensuring consistency in subsequent paging performance optimization results.

[0150] In this embodiment, by providing a paging mechanism, the terminal and the network side device can collaboratively confirm the cause of the paging failure, thereby optimizing the paging performance and ensuring the reliability of sending and receiving subsequent paging messages.
