The network-side device 12 can include an access network device or a core network device. Among them, the access network device can also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device can include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node, etc.Among them, the base station may be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), home Node B (HNB), home evolved Node B, Transmission Reception Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0039] The core network device may include, but is not limited to, at least one of the following: core network node, core network function, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0040] In addition, for the convenience of understanding this solution, the technical terms involved in the embodiments of this application are briefly introduced as follows.

[0041] 1. Paging function

[0042] The paging function is that the terminal needs to receive information from the network side device to find the terminal at a specific location, and the specific location is the Paging Frame (PF), Paging Occasion (PO), etc. Among them, the PO may include the subframe of the paging message of the terminal. The PF is the radio frame for the user to send the paging message and may include one or more POs.

[0043] In one implementation, after discontinuous reception (DRX) is enabled, in order to save power, the terminal only listens to its own PO within the DRX cycle.

[0044] 2. Paging Early Indication (PEI)

[0045] For a terminal in the idle state, it is necessary to measure the synchronization signal block (SSB) and receive paging within each paging cycle. Among them, paging reception includes the terminal listening to the paging physical downlink control channel (PDCCH) on its associated PO, and further receiving the paging physical downlink shared channel (PDSCH) after detecting the paging PDCCH.

[0046] Among them, multiple terminals can be associated with one PO. Therefore, the terminal may be woken up by mistake because other terminals in the same group are paged to listen to the paging PDCCH and paging PDSCH. It is not until it is confirmed that the terminal identifier (ID) of the terminal is not in the paging PDSCH that the terminal will go to sleep. 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 woken up by mistake, resulting in unnecessary listening power consumption of the terminal.

[0047] To reduce the power consumption of the terminal, the R17 standard further introduces PEI information based on PDCCH, that is, the terminal first receives the PEI information before receiving the paging PDCCH, and the terminal determines whether to listen to the subsequent paging PDCCH according to the content indicated in the paging early indication PEI downlink control information (DCI). The advantage is that the terminal can judge in advance whether to receive the paging PDCCH according to the PEI. If the PEI indicates that the terminal does not receive the paging PDCCH, then the terminal does not need to detect one or more SSBs between the PEI and the PO subsequently, thus achieving power saving.

[0048] In addition, PEI also has the function of further grouping the terminal group of a PO. For example, PEI associates with and indicates a PO. 8-bit information is carried in PEI for further terminal grouping indication of the PO. Among them, each bit corresponds to a subgroup, that is, a total of 8 subgroups can be indicated for early paging indication. Thus, the terminals associated in a PO are further divided into 8 subgroups, and PEI indication is performed for each subgroup, which can reduce the probability of incorrect wake-up of the terminal, thereby reducing the paging listening power consumption of the terminal.

[0049] 3. Low Power Wake-up Signal (LP-WUS)

[0050] LP-WUR can also be referred to as 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 the main communication module (in this application, also referred to as the main receiver) for transceiver of mobile communication data. The second module is a low-power receiving module (also referred to as a 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 LP-WUS in the energy-saving state and turns off the main communication module. When downlink data arrives, the network-side device 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.

[0051] In order 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 matching filtering and signal processing with relatively low power consumption.

[0052] On the network 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 RF transceiver and baseband processing modules.

[0053] Such wake-up signals are generally some relatively simple on-off keying signals. The time-domain pattern of the on-off keying signal is as Figure 1b shown. In this way, the receiver can obtain the wake-up notification through simple energy detection and subsequent possible 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 operate at a relatively low power consumption level, so as to achieve power consumption savings by receiving the wake-up signal.

[0054] The low-power wake-up signal can carry a small amount of payload, such as 10-bit information.

[0055] The reception of the low-power wake-up signal can be applied to terminals in the Radio Resource Control (RRC)_idle or RRC_inactive state, and can also be applied to terminals in the RRC_connected state, so as to achieve energy saving for the terminals.

[0056] For example, for terminals in RRC_idle or RRC_inactive, the terminal can first listen to the LP-WUS signal to determine whether to listen to the PEI or Paging DCI.

[0057] Based on this, the technical solutions provided by the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings through some embodiments and their application scenarios.

[0058] As Figure 2 shown, it is a schematic flowchart of a paging method 200 provided by an exemplary embodiment of the present application. The method 200 can be but is not limited to being executed by a terminal, and can be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 200 may at least include the following steps.

[0059] S210, the terminal receives first information from the network-side device.

[0060] Among them, the first information is used to indicate information related to the paging message transmission, so that the terminal can analyze the paging failure reason according to the information related to the paging message transmission, and then optimize the paging performance, etc. It can be 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.

[0061] In an optional implementation manner, the first information may include at least one of 11)-14).

[0062] 11) Information about the first object related to the paging message transmission.

[0063] Among them, the information of the first object may include, but is not limited to, at least one of the identifier of the RNA for which 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.

[0064] The paging initiation time may be, but is not limited to, PF, PO, the PDCCH listening occasion, the paging time period, etc.

[0065] It should be noted that there can be multiple ways for the terminal to determine the paging failure reason based on the information of the first object. For example, assuming that the information of the first object is the identifier of the RAN, then the terminal determines whether it is in the RAN area corresponding to the identifier of the RAN or determines whether the downlink signal quality of the RAN area corresponding to the identifier of the RAN meets the requirements, etc. If the terminal determines that it is not in the RAN area corresponding to the identifier of the RAN or determines that the downlink signal quality of the RAN area corresponding to the identifier of the RAN does not meet the requirements, it can be determined that the paging failure reason at least includes that the terminal determines that it is not in the RAN area corresponding to the identifier of the RAN or determines that the downlink signal quality of the RAN area corresponding to the identifier of the RAN does not meet the requirements.

[0066] Another example, assuming that the information of the first object is the terminal identifier, then the terminal can determine whether the terminal identifier is consistent with its own terminal identifier. If not, it can be determined that the paging failure reason at least includes inconsistent terminal identifiers. That is, the terminal identifier during the paging message transmission by the network-side device is inconsistent with the identifier of the terminal to be paged as expected, resulting in an incorrect paging message transmission. Subsequently, the network-side device does not receive a paging response sent by the terminal to be paged as expected, that is, the paging fails.

[0067] Still another example, assuming that the information of the first object is the paging initiation time, then the terminal can determine whether to receive the paging message 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 paging failure reason at least includes that the paging initiation time is inconsistent with the time when the terminal receives the paging message.

[0068] It should be noted that the process of determining the paging failure reason based on other information of the first object is similar to that of the RAN identifier, terminal identifier, and paging initiation time described above, and will not be elaborated here.

[0069] 12) Whether a paging optimization mechanism is applied when sending the paging message. Among them, the paging optimization mechanism may include, but is not limited to, PEI, LP-WUS, etc. The relevant descriptions of PEI and LP-WUS are not elaborated here.

[0070] It should be noted that when the terminal determines the paging failure reason based on "whether a paging optimization mechanism is applied when sending the paging message", the implementation process may include, but is not limited to: assuming that a 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 paging failure reason is that the terminal does not receive PEI.

[0071] 13) When sending the paging message, the RRC state of the terminal expected or desired by the network side device, such as RRC-idle state, RRC-inactive state, etc.

[0072] It should be noted that when the terminal determines the paging failure reason based on "the RRC state of the terminal expected or desired by the network side device when sending the paging message", the 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, it can be determined that the paging failure reason 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.

[0073] 14) The paging sending mechanism corresponding to the paging message. Among them, the paging sending mechanism may include, but is not limited to, RAN paging mechanism, core network paging mechanism, etc., and is not limited here.

[0074] It should be noted that when the terminal determines the paging failure reason based on "the paging sending mechanism corresponding to the paging message", the implementation process may include, but is not limited to: assuming that the paging sending mechanism is the RAN paging mechanism, then the terminal can determine whether it enables the RAN paging mechanism. If it does not enable it, it is determined that the paging failure reason at least includes that the terminal does not enable the RAN paging mechanism.

[0075] In this embodiment, the first information may be sent by the network side device to the terminal independently, or may be requested or subscribed by the terminal from the network side device, etc., and is not limited here.

[0076] It should be noted that the network-side device mentioned in the embodiments of the present application may be, but is not limited to, a RAN node or a core network node. The RAN node may be, but is not limited to, a gNB node, etc., and the core network node may be, but is not limited to, an AMF, a UDM, etc.

[0077] Correspondingly, the paging message may be initiated by a RAN node or a core network node, etc., and is not limited herein.

[0078] S220, determine the paging failure reason according to the first information.

[0079] In this embodiment, when the terminal determines the paging failure reason, in addition to based on the first information, it may also combine the first information and the relevant information collected independently within the paging failure time range to determine the paging failure reason, etc., which is not limited herein. Among them, the relevant information within the paging failure time range may be, but is not limited to, the relevant information of the terminal within the paging failure time range, such as the movement path of the terminal, the cell information where the terminal camps, 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 cell where the terminal camps when it is not in the service area, the first cell where the terminal camps when it returns to the service area, etc. It can be understood that the "service area" mentioned in the embodiments of the present application can also be understood as the network coverage area, etc.

[0080] In an optional implementation manner, the paging failure reason may include, but is not limited to, that the downlink signal quality does not meet the requirements, the terminal is in an abnormal state, the terminal does not receive a paging DCI or PEI or LP-WUS within a predetermined time, and the terminal receives a paging DCI within a predetermined time but does not receive at least one of the PDSCHs scheduled by the paging DCI.

[0081] Among them, "the downlink signal quality does not meet the requirements" may 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 by the PO is lower than a predetermined value, etc., which is not limited herein. The downlink signal quality may be represented by, but is not limited to, the reference signal received power (RSRP), the reference signal received quality (RSRQ), the signal to interference plus noise ratio (SINR), etc.

[0082] "The terminal is in an abnormal state" may include, but is not limited to, the terminal being in flight mode, the terminal being shut down, the terminal being out of service area, etc.

[0083] It can be understood that after determining the paging failure reason, the terminal can autonomously optimize the paging performance according to the paging failure reason, or can notify and the network-side device can optimize the paging performance according to the paging failure reason, etc., which is not limited here. It should be noted that the "paging performance optimization" mentioned in the embodiments of the present application can also be called paging failure performance optimization, etc.

[0084] Of course, whether the paging performance is optimized by the terminal or the network-side device, both have a consistent understanding of the performance optimization result.

[0085] In this embodiment, the terminal receives, from the network-side device, first information for indicating information related to the transmission of a paging message, and determines the paging failure reason according to the first information. Thus, the determination of the paging failure reason is realized, and further the optimization of the paging performance based on the paging failure reason is realized, the paging performance is improved, and the reliable reception and transmission of subsequent paging messages are ensured.

[0086] As Figure 3 shown, it is a schematic flowchart of a paging method 300 provided by an exemplary embodiment of the present application. The method 300 can be, but is not limited to, executed by a terminal, and can specifically be executed by hardware or software installed in the terminal. In this embodiment, the method 300 can at least include the following steps.

[0087] S310, the terminal sends third information or fourth information to the network-side device.

[0088] Among them, the third information is used to subscribe to a paging failure event notification, and the fourth information is used to indicate the capabilities related to paging failure optimization supported by the terminal, so that when a paging failure event occurs, the network-side device can send subsequent first information, that is, information related to the transmission of a paging message, to the terminal according to the paging failure event subscribed by the terminal and the paging failure optimization capabilities supported by the terminal, for analyzing and determining the paging failure reason, etc.

[0089] The foregoing "paging failure event notification" means that after a paging failure event occurs, the network-side device needs to send a notification to the terminal to inform the terminal that a paging failure or a paging failure event has occurred.

[0090] In an optional implementation manner, the paging failure event may include, but is not limited to, any one of the following 21)-23).

[0091] 21) A paging failure occurs for the terminal.

[0092] 22) There are N consecutive paging failures for the terminal; where N is an integer greater than or equal to 1.

[0093] 23) There are M paging failures for the terminal within a predetermined time window. Where M is an integer greater than or equal to 1, and the predetermined time window can be configured by means such as protocol agreement.

[0094] That is to say, 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, in the case of a paging failure for the terminal, or N consecutive paging failures for the terminal, or M paging failures for the terminal within a predetermined time window, the network side device needs to record the paging failure information.

[0095] In an optional implementation manner, 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 the information of the first object related to the paging message transmission, whether a paging optimization mechanism is applied when sending the paging message, the expected RRC state of the terminal by the network side device when sending the paging message, the paging sending mechanism corresponding to the paging message, etc.

[0096] 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 - 2, thereby improving the transmission flexibility of the third information.

[0097] Manner 1: The terminal sends the third information to the network side device during the registration process. Where the registration process may be but is not limited to when the terminal registers with the AMF, the AMF obtains the subscription information of the terminal from the UDM, and this subscription information contains the third information, that is, the paging failure event notification that the terminal needs to subscribe to.

[0098] Manner 2: The terminal sends the third information to the network side device in the RRC connected state, that is, the third information is requested by the terminal from the network side device in the RRC connected state.

[0099] In addition, for the case where the fourth information is used to indicate the capabilities of the terminal supported and related to paging failure optimization, it can be used by the network side device to determine whether to provide the first information to the terminal. For example, when the terminal supports the paging failure optimization capability, then send the first information to the terminal, etc.

[0100] In an alternative implementation, the fourth information may include, but is not limited to, at least one of the following 31)-35).

[0101] 31) The terminal supports a first capability, which is the capability to optimize paging performance based on information related to paging message transmission or paging failure reasons provided by the network side device, that is, the terminal has the capability to optimize paging performance based on information related to paging message transmission or paging failure reasons provided by the network side device. Among them, the information related to paging message transmission can be understood as the aforementioned first information, which will not be elaborated here.

[0102] 32) The terminal supports the collection and caching of fifth information, which is used to indicate relevant information when the terminal receives paging messages. Optionally, the fifth information can be used by the terminal to independently combine the first information sent by the network side device to determine the paging failure reason, optimize paging failure performance, etc., or the fifth information can also be used by the network side device to determine the paging failure reason, optimize paging failure performance, etc., which is not limited here.

[0103] In an alternative implementation, the fifth information includes at least one of the following 321)-327).

[0104] 321) Seventh information, where the seventh information includes at least one of the terminal's movement path, the cell information where the terminal camps, the downlink signal quality, the paging reception mechanism adopted by the terminal, and the RRC state where the terminal is located.

[0105] The terminal's movement path can be, but is not limited to, the longitude, latitude, altitude, etc. of multiple points on the terminal's movement path.

[0106] The cell information where the terminal camps can be, but is not limited to, the residence duration, residence time period, cell ID of the cell where the terminal camps, etc.

[0107] The downlink signal quality may include, but is not limited to, RSRP, RSRQ, SINR, etc.

[0108] The paging reception mechanism adopted by the terminal may include, but is not limited to, whether the terminal listens to PEI or LP-WUS, PEI packet information, LP-WUS packet information, etc.

[0109] The RRC state where the terminal is located may include, but is not limited to, whether the terminal is in the RRC-idle state or the RRC-inactive state, etc.

[0110] 322) The time information corresponding to the seventh piece of information. For example, if the seventh piece of information is the movement path of the terminal, the time information may be, but is not limited to, the time stamp, time period, paging moment, etc. corresponding to the movement path of the terminal.

[0111] Similarly, when the seventh piece of information is other information, it is similar to the movement path of the terminal described above and will not be elaborated here.

[0112] 323) Whether the terminal is in the service area.

[0113] 324) The time when the terminal is not in the service area.

[0114] 325) The last cell where the terminal stayed before it was not in the service area.

[0115] 326) The first cell where the terminal stays when it returns to the service area.

[0116] 327) The time when the terminal does not receive the paging message.

[0117] 33) The acquisition duration of the fifth piece of information supported by the terminal. Among them, the acquisition duration can be expressed in hours, minutes, seconds, milliseconds, superframes, frames, subframes, time slots, symbols, the number of DRX cycles, etc.

[0118] 34) The terminal supports a second capability, which is the capability to determine the paging failure reason based on the information related to paging message transmission provided by the network side device, that is, the terminal has the capability to determine the paging failure reason based on the information related to paging message transmission provided by the network side device, so as to be used for the terminal or the network side device to optimize the paging performance according to the paging failure reason. Among them, the information related to paging message transmission can be understood as the aforementioned first piece of information and will not be elaborated here.

[0119] 35) The terminal supports a third capability, which is the capability to report the paging failure reason, that is, the terminal has the capability to report the independently determined paging failure reason, so that the network side device can optimize the paging performance according to the paging failure reason.

[0120] Optionally, after receiving the fourth information, the network-side device may determine a subsequent paging performance optimization process according to the fourth information. For example, if the fourth information includes that the terminal supports the first capability, then the network-side device may send the first information to the terminal to determine the cause of paging failure, optimize paging performance, etc.; for another example, if the terminal supports the collection and caching of the fifth information, then the network-side device may request the terminal to report the fifth information to determine the cause of paging failure, optimize paging performance, etc. according to the fifth information, ……, which is not limited here.

[0121] It should be noted that the sending order of the foregoing third information and fourth information is not limited. For example, the terminal may send the third information and the fourth information simultaneously, or may send the third information first and then the fourth information, or may send the fourth information first and then the third information, etc.

[0122] In addition, in this embodiment, the receiving 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.

[0123] S320, the terminal receives the first information from the network-side device.

[0124] Wherein, the first information is used to indicate information related to paging message transmission.

[0125] S330, determine the cause of paging failure according to the first information.

[0126] It can be understood that the implementation processes of steps S320 and S330 may refer to the relevant descriptions in the foregoing method embodiment 200. Of course, in addition, as an alternative implementation manner, when determining the cause of paging failure, in addition to the first information sent by the network-side device, the terminal may also determine the cause of paging failure according to the fifth information collected or cached by itself, that is, the terminal may determine the cause of paging failure according to the first information and the fifth information.

[0127] Based on this, after determining the cause of paging failure, the terminal may independently optimize the paging performance according to the cause of paging failure, such as modifying paging configuration, modifying terminal status, etc., to ensure reliable reception of subsequent paging messages.

[0128] Alternatively, the terminal may also send the second information to the network-side device, so that the network-side device optimizes the paging performance according to the information such as the cause of paging failure indicated by the second information, such as modifying paging configuration, etc., to ensure reliable reception of subsequent paging messages.

[0129] An optional implementation manner, the second information may include but is not limited to at least one of the following 41)-47).

[0130] 41) The paging failure reason.

[0131] Wherein, the paging failure reason may include but is not limited to that the downlink signal quality does not meet the requirements, the terminal is in an abnormal state, the terminal does not receive paging DCI or PEI or LP-WUS within a predetermined time, and the terminal receives paging DCI within a predetermined time but does not receive at least one of the PDSCH scheduled by the paging DCI.

[0132] Wherein, "the 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 by the PO is lower than a predetermined value, etc., which is not limited herein.

[0133] "The terminal is in an abnormal state" may include but is not limited to that the terminal is in flight mode, the terminal is powered off, the terminal is out of service area, etc.

[0134] 42) The occurrence time of the paging failure event corresponding to the paging failure reason. For example, the paging moment, paging time period, etc. corresponding to the paging failure event, and the paging moment may be but is not limited to paging identifier, PO, PF, etc.

[0135] 43) The paging reception mechanism adopted by the terminal. For example, when paging fails, whether the terminal listens to PEI or LP-WUS, the PEI packet information of the PEI listened to by the terminal, the LP-WUS packet information of the LP-WUS listened to by the terminal, the DRX configuration or eDRX configuration adopted by the terminal, etc.

[0136] 44) The occurrence time of the paging failure event corresponding to the paging reception mechanism adopted by the terminal.

[0137] 45) The suggestions of the terminal on the paging configuration information. For example, the DRX period, eDRX period, the number of POs included in one PF, the paging occasion corresponding to the first PDCCH monitoring occasion (first PDCCH-Monitoring Occasion of PO), the paging frame offset, etc. paging parameters suggested by the terminal according to the paging failure reason.

[0138] 46) Suggestions of the terminal for the paging sending mechanism. For example, whether to configure PEI, whether to configure LP-WUS, how to configure the PEI group, how to configure the LP-WUS group, etc. suggested by the terminal according to the paging failure reason.

[0139] 47) Suggestions of the terminal for the paging sending power. For example, whether to increase the paging sending power suggested by the terminal according to the paging failure reason.

[0140] Of course, in addition to the terminal determining the paging failure reason as described above, as an alternative implementation, the network-side device can also independently determine the paging failure reason, optimize the paging performance, etc.

[0141] For example, the network-side device can also send the sixth information to the terminal to indicate the paging loss time range; correspondingly, the terminal receives the sixth information sent by the network-side device and sends the fifth information within the paging loss time range to the network-side device, so that the network-side device can determine the paging failure reason according to the received fifth information and the independently determined first information, and then optimize the paging performance based on the determined paging failure reason to ensure the reliable sending of subsequent paging messages. Herein, the "paging loss time range" can be understood as the time range during which the network-side device sends a paging message but does not receive a paging response from the terminal.

[0142] Optionally, when the network-side device sends the sixth information to the terminal, it can independently determine the sending timing, or can be sent according to the received third information or fourth information sent by the terminal. For the case of sending according to the received third information or fourth information sent by the terminal, it can be understood that for the terminal, the receiving time of the sixth information is later than the sending time of the third information or the fourth information.

[0143] In an alternative implementation, the sixth information can be sent to the terminal through a paging message or through a dedicated signaling, which is not limited herein.

[0144] It should be noted that if the network-side device determines the paging failure reason according to 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 mobile path of the terminal and the cell information where the terminal camps, the terminal can report non-actual or non-real mobile path and camping cell information while reporting the actual or real mobile path and camping cell information to avoid the exposure of the terminal's privacy and ensure communication security.

[0145] That is to say, when the terminal reports the fifth piece of information, the movement path of the terminal therein may include the actual movement path and the non-actual movement path of the terminal; or, the cell information where the terminal resides includes the cell information where the terminal actually resides and the non-actual cell information where the terminal resides. For example, the terminal is allowed to report in the fifth piece of information that the terminal resides in multiple cells and has multiple movement paths at the same time point, etc.

[0146] In addition, for the case where the network-side device independently determines the cause of paging failure based on the fifth piece of information and the first piece of information, at the same time, the terminal can also determine the cause of paging failure according to the first piece of information sent by the network-side device and the fifth piece of information collected independently. That is, in this application, the cause of paging failure can be determined and paging performance optimized only by the terminal or the network-side device, or both can determine the cause of paging failure and optimize paging performance, which is not limited herein.

[0147] Of course, no matter which party determines the cause of paging failure, it can send it to the other party after determining the cause of paging failure, so as to ensure the consistency of understanding of the cause of paging failure between the two, and further ensure the consistency of the subsequent paging performance optimization results.

[0148] In this embodiment, by providing a paging mechanism, it is possible to enable the terminal and the network-side device to jointly confirm the cause of paging failure, so as to optimize paging performance and ensure the reliable sending and receiving of subsequent paging messages.
