The base station is not limited to a specific technical term, and it should be noted that in the embodiments of the present 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.

[0050] The core network device can also be referred to as a core network node, a core network function, or a core network network element, etc., which includes but is not limited to at least one of the following: a mobility management entity (MME), an access and mobility management function (AMF), a session management function (SMF), a user plane function (UPF), a policy control function (PCF), a policy and charging rules function (PCRF), an edge application server discovery function (EASDF), a unified data management (UDM), a unified data repository (UDR), a home subscriber server (HSS), a centralized network configuration (CNC), a network repository function (NRF), a network exposure function (NEF), a local NEF (L-NEF), a binding support function (BSF), an application function (AF), a location management function (LMF), a gateway mobile location center (GMLC), a network data analytics function (NWDAF), etc. It should be noted that only the core network device in the NR system is taken as an example for introduction in the embodiments of the present application, and the specific type of the core network device is not limited. If the name of the core network device mentioned in the embodiments of the present application changes in the subsequent protocol version (for example, 6G), it is also within the protection scope of the present application.

[0051] Optionally, the core network device can be implemented by one or more function modules in one device, or can be implemented by multiple devices jointly, and the embodiments of the present application do not make a specific limitation in this regard. It can be understood that the function modules described above can be network elements in a hardware device, can be software function modules running on a dedicated hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0052] For the convenience of understanding the embodiments of the present application, a non-terrestrial network (NTN) related to the present application is described.

[0053] The non-terrestrial network refers to a network or network segment using a satellite (Satellite) or unmanned aerial system (Unmanned Aircraft System, UAS) platform for transmission. Compared with a ground communication system, a satellite-based non-terrestrial communication system has a more extensive coverage range, and typical scenarios include continuous coverage in remote mountainous areas, deserts, oceans, forests, or emergency communication when a ground base station is damaged due to natural disasters.

[0054] In the embodiments of the present application, the satellite includes but is not limited to a low earth orbiting (Low Earth Orbiting, LEO) satellite, a medium earth orbiting (Medium Earth Orbiting, MEO) satellite, a geostationary earth orbiting (Geostationary Earth Orbiting, GEO) satellite, and a highly elliptical orbiting (Highly Elliptical Orbiting, HEO) satellite.

[0055] FIG. 2 shows a typical NTN deployment scenario, in which the link between the UE and the satellite is called a service link (Service link), and the link between the satellite and the ground gateway is called a feeder link (Feeder link). In some scenarios (such as low earth orbiting satellites LEO), due to the movement of the satellite, switching of the Service link and / or the Feeder link occurs. For Service link switching, the serving satellite of all UEs in the cell needs to be switched from one satellite to another satellite. For Feeder link switching, a certain satellite needs to be switched from one ground gateway to another ground gateway.

[0056] The NTN communication system includes a transparent payload-based NTN communication system and a regenerative payload-based NTN communication system. For the transparent payload-based NTN communication system, the terminal, the base station, and the core network device are all deployed on the ground, and the communication data between the terminal and the network device is transferred via the satellite in the air. In the transparent payload-based NTN communication system, the satellite only forwards the data between the base station and the terminal, and does not decode and process the data. For the regenerative payload-based NTN communication system, the satellite has part or all of the base station function, and can decode and process the uplink or downlink data.

[0057] For the convenience of understanding the embodiments of the present application, the paging process related to the present application is described.

[0058] As shown in FIG. 3, step 1: when there is downlink data or signaling to be sent to a certain radio resource control (RRC) idle state terminal, the AMF pages the terminal through the paging process, and the AMF sends the paging to the RAN node covered by the registration area (RA) of the terminal.

[0059] Step 2: After the RAN node receives the paging, the RAN node needs to perform paging on the terminal located in the tracking area identity (TAI) list for paging. For each cell belonging to the tracking area (TA) indicated in the TAI list for paging, the RAN node generates a paging message on the air interface.

[0060] For the core-initiated paging process, such as when the terminal is in the RRC idle state (RRC_IDLE), the terminal will respond to the paging after receiving the paging, triggering the non-access layer (NAS) connection establishment (corresponding to the RRC connection establishment), and the NAS connection establishment is generally a service request process or a registration update (TAU) process.

[0061] If the terminal is in the RRC inactive state (RRC_INACTIVE), the paging is initiated by the RAN node, which is called RAN paging, and the base station sends the RAN notification / paging message to the terminal, and the terminal responds to the notification / paging to perform the RRC resume process, etc.

[0062] For the convenience of understanding the embodiments of the present application, a paging alert service (Paging Alert Service) process related to the present application is described.

[0063] In a satellite scenario, a handheld terminal of a user generally has a gesture requirement and an alignment process to obtain a better satellite communication channel condition. Therefore, when the handheld terminal is placed in a concealed place such as a backpack, a pocket, a car, and the like, the downlink channel becomes very poor, so that a paging message cannot be received. Therefore, how to notify the terminal to ensure the paging reachability of the terminal is an urgent problem to be solved.

[0064] The notification method provided by the embodiments of the present application is described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0065] FIG. 4 is a schematic diagram of a notification method provided by an embodiment of the present application. As shown in FIG. 4, the method 200 includes at least part of the following content:

[0066] S210, a first network side device receives a target message on a target channel.

[0067] Correspondingly, a terminal receives a target message on a target channel, wherein the target message is used to notify the terminal based on a paging alert operation.

[0068] In some embodiments, the target message is a paging message or a message specially used for the paging alert operation.

[0069] In the embodiments of the present application, the message specially used for the paging alert operation is referred to as a paging alert message, a paging alert notification message, a resilient notification message, a paging robust notification message, or other expressions, which are not limited in the present application. The paging alert message is taken as an example for description below, but the present application is not limited thereto.

[0070] In some embodiments, the terminal is in an RRC non-connected state, for example, an RRC_IDLE state or an RRC_INACTIVE state.

[0071] Optionally, the embodiments of the present application can be applied to, but are not limited to, the following scenarios:

[0072] Scenario 1: The terminal can normally receive a paging message, but the terminal fails in random access, for example, due to poor channel conditions of the terminal, for example, in an elevator, a basement, or the like, where the network coverage is poor.

[0073] Scenario 2: The terminal cannot normally receive a paging message. For example, a paging process fails.

[0074] In some embodiments, the first network-side device can be an access network device, e.g., an access network device within a paging area of the terminal. For example, if the terminal is in an RRC_IDLE state, the first network-side device can include at least one access network device within a core network tracking area (TA) to which the terminal belongs. For another example, if the terminal is in an RRC_INACTIVE state, the first network-side device can include at least one access network device within an access network tracking area (RNA) to which the terminal belongs.

[0075] In some embodiments, the target channel includes the first channel, or the target channel includes a second channel different from the first channel.

[0076] In some embodiments, the first channel is a channel for transmitting a paging message, e.g., a Paging Control Channel (PCCH).

[0077] In some embodiments, the second channel can be a channel for transmitting a paging pre-warning message. Optionally, the second channel can be a newly added channel dedicated for transmitting a paging pre-warning message.

[0078] In some embodiments, the terminal can determine that the first network-side device notifies the terminal based on a paging pre-warning operation according to the target message and / or the target channel. For example, if the target message is a paging pre-warning message, or the target message carries paging pre-warning related information, e.g., paging pre-warning auxiliary information. For another example, the target channel is a channel related to a paging pre-warning operation, e.g., a channel for transmitting a paging pre-warning message, or a channel for transmitting a message carrying paging pre-warning related information, e.g., paging pre-warning auxiliary information.

[0079] In some embodiments, the first network-side device sending the target message on the target channel can be triggered by the first network-side device.

[0080] In some other embodiments, the first network-side device sending the target message on the target channel can be based on control of a second network-side device.

[0081] For example, the first network-side device is an access network device (e.g., a serving base station of the terminal), and the second network-side device is a core network device (e.g., a serving AMF of the terminal). Optionally, when the terminal is in an RRC_IDLE state, the serving AMF of the terminal can control the serving base station of the terminal to send the target message on the target channel.

[0082] For example, the first network-side device is a first access network device (e.g., the terminal's serving base station), and the second network-side device is a second access network device (e.g., the terminal's anchor base station). Optionally, when the terminal is in the RRC_INACTIVE state, the terminal's anchor base station controls the terminal's serving base station to send the target message on the target channel.

[0083] In summary, paging warning operations can be triggered by either a first network-side device or a second network-side device. In other words, paging warning operations can be triggered by either an access network device or a core network device.

[0084] In some embodiments, the second network-side device may send a paging message to the first network-side device, and the first network-side device may send a target message on the target channel based on the paging message.

[0085] In some embodiments of this application, the terminal receiving the target message on the target channel includes:

[0086] The terminal receives the target message on the first channel.

[0087] For example, by default, the terminal receives the target message on the first channel. Alternatively, the terminal may only listen on the first channel. In scenario 1, the terminal may receive the target message on the first channel.

[0088] In some embodiments of this application, the terminal receiving the target message on the target channel includes:

[0089] The terminal receives the target message on the second channel.

[0090] In some embodiments, the terminal defaults to listening only on the second channel, or the terminal conditionally chooses to receive the target message on either the first or second channel. For example, in scenario 2, the terminal receives the target message on the second channel if one or more conditions are met. Otherwise, it receives the target message on the first channel.

[0091] The following specific embodiments illustrate when the terminal receives the target message on the second channel.

[0092] In some embodiments, the terminal receiving a target message on a target channel includes:

[0093] The terminal receives the target message on the second channel when the first condition is met.

[0094] Optionally, receiving the target message on the second channel may include receiving a paging message or a paging warning message on the target channel.

[0095] In some embodiments, the first condition can be considered as a poor channel condition of the terminal, and the terminal can not receive the paging message on the first channel. In this case, the terminal can receive the target message on the second channel, so as to ensure that the terminal will not miss important paging and improve the paging reachability of the terminal.

[0096] In some embodiments, the first condition includes, but is not limited to, at least one of the following:

[0097] The terminal does not find a suitable cell to camp on;

[0098] The terminal is out of network coverage;

[0099] The signal quality of the serving cell of the terminal is lower than a first threshold;

[0100] The serving cell of the terminal belongs to a target area, and the target area is an area related to the paging warning operation;

[0101] The geographical position of the terminal belongs to a target area, and the target area is an area related to the paging warning operation;

[0102] The terminal does not receive the target message on the target channel within a period of time, wherein the target message includes first information.

[0103] In some embodiments, the suitable cell can satisfy the following conditions:

[0104] The quality of the cell satisfies the cell selection criterion (i.e., S criterion);

[0105] The cell is not a barred cell;

[0106] The cell does not belong to a forbidden area;

[0107] The public land mobile network (PLMN) of the cell satisfies the non-access stratum (NAS) requirement.

[0108] In some embodiments, the out-of-coverage can include a scenario that the UE does not search for a cell on a Uu frequency point supported by its wireless capability.

[0109] In some embodiments, the target area can be considered as an effective area of the paging warning operation, that is, when the terminal is in the target area, the network side device can notify the terminal through the paging warning operation.

[0110] Optionally, the target area can be obtained based on statistics and area division of cells that historically initiate paging failures.

[0111] Optionally, the first network-side device or the second network-side device can configure the target area to the terminal in advance based on the mobility of the terminal, and the terminal can start listening to the target message on the second channel when determining that the terminal moves to the target area.

[0112] In some embodiments, the terminal receives the target message on the second channel in the case where the first condition is met, including:

[0113] In the case where the first condition is met, the terminal searches for a target cell, and the target cell is a cell that supports or allows a paging early warning operation.

[0114] The terminal receives the target message on the second channel based on target configuration information of the target cell.

[0115] Optionally, whether a cell supports or allows a paging early warning operation can be determined by the terminal through system information (System Information) or system information block (System Information Block, SIB) of the cell.

[0116] Optionally, the target configuration information can be acquired by the terminal through System Information or SIB of the target cell. Optionally, the target configuration information is used to indicate receiving resources of the second channel, such as time-frequency location of the second channel, common search space (common search space), and the like.

[0117] In one specific embodiment, in the case where the first condition is met, the terminal searches for a target cell, camps on the target cell, receives system information or SIB of the target cell, acquires target configuration information, and then searches for or listens to the second channel based on the target configuration information to receive the target message.

[0118] In some embodiments, the terminal receives the target message on the second channel in the case where the first condition is met, including:

[0119] In the case where the first condition is met, the terminal searches for a target reference signal, and the target reference signal is associated with the second channel.

[0120] The terminal receives the target message on the second channel based on the target reference signal.

[0121] Optionally, the target reference information can be SSB, or can also be other periodically transmitted reference signals, which are not limited in the present application.

[0122] Optionally, the target reference signal is associated with the second channel, including:

[0123] The resource position of the target reference signal and the resource position of the second channel have an association relationship.

[0124] Optionally, the resource configuration can be identified by at least one of the following dimensions: time domain, frequency domain, space domain, code domain.

[0125] For example, the time-frequency resource position of the second channel and the time-frequency resource position of the target reference signal have a fixed offset, and the terminal determines the time-frequency resource position of the second channel according to the time-frequency resource position of receiving the target reference signal combined with the fixed offset.

[0126] Optionally, the target reference signal is associated with the second channel, including:

[0127] The target reference signal can be used to indicate the resource position of the second channel.

[0128] For example, the time-frequency resource position or pattern of the target reference signal can be used to indicate the time-frequency resource position of the second channel, so that the terminal can determine the time-frequency resource position of the second channel according to the time-frequency resource position or pattern of the target reference signal, and then can search or listen to the second channel on the time-frequency resource position of the second channel.

[0129] In some embodiments of the present application, the target message includes paging early warning auxiliary information, which is used to assist in determining whether the target message is related to the paging early warning operation, or in other words, whether the target message informs the terminal based on the paging early warning operation.

[0130] In some embodiments, the paging early warning auxiliary information includes but is not limited to at least one of the following:

[0131] The first indication information is used to indicate whether the target message is used to notify the terminal based on the paging early warning operation, or whether the target message is related to the paging early warning operation;

[0132] The second indication information is used to indicate whether the network side device supports the paging early warning operation, or whether the paging early warning operation is allowed;

[0133] The first identification information is used to identify the source terminal of the paging early warning operation.

[0134] The service type information is used to identify the service type of the paging early warning operation.

[0135] Optionally, the first indication information can be represented by 1 bit, and different values of the 1 bit are used to indicate whether the target message is used for notifying the terminal based on the paging early warning operation or not. For example, a value of 1 indicates that the target message is used for notifying the terminal based on the paging early warning operation, and a value of 0 indicates that the target message is not used for notifying the terminal based on the paging early warning operation. Optionally, the value of the first indication information in the default case can follow the definition of the value of 1 or the definition of the value of 0.

[0136] Optionally, the second indication information can also be represented by 1 bit, and different values of the 1 bit are used to indicate whether the network side device supports the paging early warning operation or not, or whether the paging early warning operation is allowed or not. For example, a value of 1 indicates that the network side device supports the paging early warning operation or the paging early warning operation is allowed, and a value of 0 indicates that the network side device does not support the paging early warning operation or the paging early warning operation is not allowed. The network side device here can include a first network side device (for example, an access network device serving the terminal) and / or a second network side device (for example, a core network device serving the terminal). For example, according to the triggering mechanism of the paging early warning operation, the content indicated by the second indication information can come from the core network device or the access network device. For example, the paging early warning operation is triggered by the core network device, and the second indication information can be used to indicate whether the core network device (for example, an AMF) supports the paging early warning operation or allows the paging early warning operation. For another example, the paging early warning operation is triggered by the access network, and the second indication information can be used to indicate whether the access network device (for example, a base station) supports the paging early warning operation or allows the paging early warning operation. Optionally, the value of the second indication information in the default case can follow the definition of the value of 1 or the definition of the value of 0.

[0137] In some embodiments, the first identification information is used to identify a source terminal of the paging early warning operation or a sender terminal of downlink data or signaling. By carrying the first identification information in the target message, the receiver terminal of the target message can know the source terminal of the paging early warning operation, so that the receiver terminal can receive the downlink data or signaling of the source terminal in time after the access is successful.

[0138] Optionally, the first identification information can include but is not limited to at least one of the following:

[0139] a first system architecture evolution (SAE) temporary mobile station identifier (S-TMSI) used to identify the source terminal;

[0140] a first non-activated radio network temporary identifier (I-RNTI) for identifying the source terminal.

[0141] In some embodiments, the target message further comprises second identification information for identifying a target terminal of the paging pre-warning operation, or in other words, a receiving terminal of the target message, i.e., the terminal in the embodiments of the present application.

[0142] Optionally, the second identification information can include, but is not limited to, at least one of the following:

[0143] a second S-TMSI for identifying the target terminal;

[0145] In some embodiments, the first network-side device can send the target message to the terminal when there is downlink data or signaling, the source terminal identified by the first identification information can be a sending terminal of the downlink data or signaling, and the target terminal identified by the second identification information can be a receiving terminal of the downlink data or signaling, i.e., the source terminal has downlink data or signaling to be sent to the target terminal. Optionally, the target terminal is in a non-connected state, such as an RRC_IDLE or RRC_INACTIVE state.

[0146] Optionally, when there is downlink data or signaling, the first network-side device can first initiate a paging process for the target terminal, and then trigger the paging pre-warning operation for the target terminal after determining that the paging fails, i.e., after the paging fails, the target message is sent on the target channel, or the paging pre-warning operation for the target terminal can be directly triggered, i.e., the paging process is skipped, i.e., the target message is directly sent on the target channel.

[0147] Optionally, in the case where the source terminal subscribes to the paging pre-warning operation for notifying the target terminal (or in other words, the source terminal and the target terminal establish a binding relationship related to the paging pre-warning operation), the first network-side device can trigger the paging pre-warning operation for the target terminal when the source terminal has downlink data or signaling to be sent to the target terminal. For other terminals that do not subscribe to the paging pre-warning operation for notifying the target terminal, the first network-side device does not trigger the paging pre-warning operation for the target terminal when the source terminal has downlink data or signaling to be sent to the target terminal.

[0148] In some embodiments, the service type information can be a service type triggering the paging pre-warning operation, or in other words, a service type of the source terminal to be sent to the target terminal, and the first network side device can determine whether the service to be sent by the source terminal is an emergency or important service according to the service type, so as to determine whether to trigger the paging pre-warning operation for the target terminal.

[0149] In some embodiments, the service type information includes but is not limited to at least one of the following:

[0150] Voice service, emergency service, public safety service.

[0151] In some embodiments, when the service to be sent by the source terminal is the above-mentioned service type, the first network side device determines to trigger the paging pre-warning operation for the target terminal.

[0152] In some embodiments, the terminal receives the paging pre-warning message on the first channel, and the terminal determines that the first network side device notifies the terminal based on the paging pre-warning operation based on the message received on the first channel.

[0153] In other embodiments, the terminal receives the paging message on the first channel, and the terminal determines that the first network side device notifies the terminal based on the paging pre-warning operation based on the paging pre-warning assistance information included in the paging message received on the first channel.

[0154] In yet other embodiments, the terminal receives the paging message on the second channel, and the terminal can determine that the first network side device notifies the terminal based on the paging pre-warning operation based on the channel on which the paging message is received, which is the second channel.

[0155] In some embodiments, the terminal receives the paging message on the second channel, and based on the channel on which the paging message is received, which is the second channel, and the paging pre-warning assistance information, the terminal determines that the first network side device notifies the terminal based on the paging pre-warning operation.

[0156] In some embodiments, the terminal receives the paging pre-warning message on the second channel, and the terminal can determine that the first network side device notifies the terminal based on the paging pre-warning operation based on the paging pre-warning message and the second channel.

[0157] In some embodiments, the content carried in the target message (such as the paging pre-warning assistance information, the second identification information) can be obtained by the first network side device from the second network side device and / or the terminal.

[0158] In some embodiments of the present application, the method 200 further includes:

[0159] The access stratum (AS) of the terminal delivers the paging early warning assistance information to a non-access stratum (NAS) of the terminal.

[0160] Optionally, the access stratum (AS) of the terminal delivering the paging early warning assistance information to the non-access stratum (NAS) of the terminal comprises:

[0161] In a case that the target message includes the paging early warning assistance information and the target message includes second identification information, the second identification information matches the identification information of the terminal (i.e., the terminal is the target terminal), the AS of the terminal delivers the paging early warning assistance information to the NAS of the terminal.

[0162] In some embodiments, the method 200 further comprises:

[0163] The AS of the terminal receives first information from the NAS of the terminal, the first information comprising at least one of:

[0164] First request information, the first request information being used to request to establish a connection;

[0165] A first access category (AC) value, the first AC value corresponding to a NAS procedure triggered by the paging early warning operation;

[0166] A first cause value, the first cause value corresponding to the NAS procedure triggered by the paging early warning operation.

[0167] For example, after the AS of the terminal delivers the paging early warning assistance information to the NAS of the terminal, the NAS of the terminal can send the first information to the AS of the terminal.

[0168] In some embodiments, the first request information or the NAS request, the first AC value can be an AC value dedicated to the NAS procedure triggered by the paging early warning operation, and the first cause value can be a cause value dedicated to the NAS procedure triggered by the paging early warning operation.

[0169] In some embodiments, the method 200 further comprises:

[0170] In a case that a second condition is met, the terminal initiates a radio resource control (RRC) connection establishment or resumption procedure, wherein the second condition comprises at least one of:

[0171] The terminal searches for or camps on a cell, and a signal quality of the cell is greater than or equal to a second threshold;

[0172] A first timer of the terminal stops running or expires;

[0173] the second timer of the terminal is running or has not expired.

[0174] For example, after the AS of the terminal receives the first information, the RRC connection setup or resume procedure can be initiated if the second condition is met.

[0175] Optionally, the first timer is used to control the terminal from initiating the RRC connection setup or resume procedure too early. It can be understood that, based on the first timer, the earliest time for the terminal to send the RRC connection setup or resume message can be determined.

[0176] Optionally, the second timer is used to control the terminal from initiating the RRC connection setup or resume procedure too late. It can be understood that, based on the second timer, the latest time for the terminal to send the RRC connection setup or resume message can be determined. Optionally, if the second timer expires, the terminal can abort the RRC connection setup or resume procedure. The expiration of the second timer can be considered as the end of the pending traffic of the source terminal or the expiration of the pending traffic (e.g. the other party hangs up during a voice call), therefore, when the second timer expires, the target terminal can abort the RRC connection setup or resume procedure. Optionally, there is no need to set a stop condition for the second timer.

[0177] Optionally, in the case where the first timer and the second timer exist, the duration of the first timer is shorter than the duration of the second timer.

[0178] Optionally, the first timer of the terminal stops running or expires can also be expressed as the first timer is not running, for example, the first timer stops after being started, or the first timer is not started.

[0179] In some embodiments, the first network-side device performs the paging warning operation on the terminal because the channel condition of the terminal is poor (e.g. the terminal is in an area with poor signal coverage) and the first network-side device fails to page the terminal, or the terminal is paged multiple times and fails, therefore, the channel condition of the terminal in a period of time can not be restored, in this case, if the terminal initiates random access, it will lead to random access failure, therefore, the first timer can be used to control the terminal from initiating the RRC connection setup or resume procedure too early, thereby reducing the power consumption of the terminal.

[0180] In some embodiments, the first network-side device performs the paging warning operation on the terminal because there is downlink data or signaling to be sent to the terminal, and if random access is not initiated for a long time, it can lead to the expiration of the downlink traffic or signaling, therefore, the second timer can be used to control the terminal from initiating the RRC connection setup or resume procedure too late, thereby ensuring the timely transmission of the downlink traffic or signaling.

[0181] In some embodiments, the method 200 further comprises:

[0182] In a case where the third condition is met, the terminal starts or restarts the first timer.

[0183] In a case where the third condition is met, it indicates that the first network-side device performs the paging early warning operation on the terminal, and indicates that the channel condition of the terminal is poor. Therefore, the first network-side device needs to notify the terminal through the paging early warning operation. In this case, the terminal can start or restart the first timer to avoid the terminal prematurely initiating the RRC connection establishment or recovery procedure, resulting in power consumption of the terminal.

[0184] In some embodiments, the third condition comprises at least one of:

[0185] The terminal receives the target message;

[0186] The AS layer of the terminal delivers the paging early warning assistance information to the NAS of the terminal;

[0187] The AS layer of the terminal receives the first information of the NAS layer of the terminal.

[0188] In some embodiments, the method 200 further comprises:

[0189] In a case where the fourth condition is met, the terminal stops the first timer.

[0190] In a case where the fourth condition is met, it indicates that the channel condition of the terminal becomes good. Therefore, the terminal stops the first timer, initiates the RRC connection establishment or recovery procedure, and establishes a connection with the network side in time, so as to be able to receive downlink service or signaling in time.

[0191] In some embodiments, the fourth condition comprises at least one of:

[0192] The terminal searches for or camps on a cell, and the signal quality of the cell is greater than or equal to a third threshold;

[0193] The terminal successfully performs random access;

[0194] The terminal receives an RRC establishment or recovery message;

[0195] The terminal successfully sends an RRC connection establishment or recovery completion message;

[0196] The terminal enters an RRC connected state.

[0197] In some embodiments, the method 200 further comprises:

[0198] In a case where the fifth condition is met, the terminal starts or restarts the second timer.

[0199] When the fifth condition is met, it indicates that the first network-side device performs the paging early warning operation on the terminal, and indicates that the channel state of the terminal is poor. Therefore, the first network-side device needs to notify the terminal through the paging early warning operation. In this case, the terminal can start or restart a second timer, and initiate an RRC connection establishment or recovery procedure within the second timer, so as to avoid that the terminal initiates the RRC connection establishment or recovery procedure too late, and affects the timely transmission of downlink service or signaling.

[0200] In some embodiments, the fifth condition comprises at least one of the following:

[0201] receiving the target message;

[0202] the AS layer of the terminal delivers the paging early warning auxiliary information to the non-access stratum (NAS) layer of the terminal;

[0204] In some embodiments, the terminal initiates the RRC connection establishment or recovery procedure, comprising:

[0205] the terminal sends an RRC connection establishment or recovery request to the first network-side device, wherein the RRC connection establishment or recovery request comprises a second cause value, and the second cause value corresponds to the RRC connection establishment or recovery procedure triggered by the paging early warning operation.

[0206] Optionally, the second cause value is a special cause value for the RRC connection establishment or recovery procedure triggered by the paging early warning operation.

[0207] Optionally, the second cause value is a first cause value determined by the NAS of the terminal, or a cause value determined by the AS of the terminal.

[0208] In some embodiments of the present application, the method 200 further comprises:

[0209] the terminal does not perform unified access control (UAC) on the RRC connection establishment or recovery procedure.

[0210] That is, the terminal can skip performing UAC on the RRC connection establishment or recovery procedure triggered by the paging early warning operation.

[0211] In some embodiments of the present application, the method 200 further comprises:

[0212] the terminal performs UAC on the RRC connection establishment or recovery procedure.

[0213] For example, the terminal determines whether to initiate the RRC connection establishment or resumption procedure according to an access control parameter corresponding to a first AC value, the first AC value being an AC value indicated by the terminal when requesting connection establishment in NAS or an AC value determined by AS of the terminal.

[0214] In some embodiments, the method 200 further comprises:

[0215] The terminal receives first configuration information from the first network side device or from the second network side device, the first configuration information being used for configuring at least one of the following:

[0216] A duration of the first timer;

[0217] A duration of the second timer;

[0218] A target area, the target area being an area related to the paging early warning operation.

[0219] Optionally, the first network side device is an access network device, and the first network side device can send the first configuration information to the terminal through an RRC message.

[0220] Optionally, the second network side device is a core network device, and the second network side device can send the first configuration information to the terminal through an NAS message.

[0221] Optionally, the first configuration information can be determined by the first network side device or by the second network side device, in which case, when the first network side device sends the first configuration information to the terminal, the first network side device can first obtain the first configuration information from the second network side device.

[0222] For example, before the first network side device sends the first configuration information to the terminal, the method 200 further comprises: the first network side device receiving the first configuration information from the second network side device.

[0223] In some embodiments, the first network side device is an access network device (for example, a serving base station of the terminal), and the second network side device is a core network device (for example, a serving AMF of the terminal), the serving AMF of the terminal can configure the first configuration information to the serving base station of the terminal through an N1 interface message, and the serving base station of the terminal can forward the first configuration information to the terminal through an RRC message.

[0224] In some embodiments, the first network-side device is a first access network device (e.g., a serving base station of the terminal), and the second network-side device is a second access network device (e.g., an anchor base station of the terminal). The anchor base station of the terminal can first configure the first configuration information to the serving base station of the terminal through an Xn interface message, and the serving base station of the terminal can then forward the first configuration information to the terminal through an RRC message.

[0225] The following describes a specific flow of the notification method provided by the embodiments of the present application in combination with FIG. 5 to FIG. 7.

[0226] In the example of FIG. 5, the terminal can receive the paging message, but the random access is unsuccessful. The network-side device does not know the reason for the paging failure of the terminal, i.e., does not know whether the downlink reception of the terminal is not successful or the uplink access is not successful due to the random access failure. In this example, the network device can send the paging message on the first channel, and carry the paging early warning auxiliary information in the paging message to indicate that the paging message is used for notifying the terminal based on the paging early warning operation.

[0227] As shown in FIG. 5, the notification method can include at least part of the following steps:
