[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410515765.2, filed on April 26, 2024, entitled “Paging Monitoring Method, Terminal, Network Device and Processor-Readable Storage Medium”, which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure relates to the field of communication technology, and in particular to a paging monitoring method, a terminal, a network device, and a processor-readable storage medium. Background Technology

[0004] In satellite systems, there are wide beams and narrow spot beams. Wide beams have a larger coverage area; a single satellite can contain one or more wide beams, forming the entire satellite coverage area. Narrow spot beams (also known as hopping beams) have a very small coverage area; the coverage area of ​​one narrow spot beam is called a band position, and a satellite coverage area can contain hundreds of band positions. Each band position under satellite coverage has a paging occasion (PO), and the terminal, or User Equipment (UE), listens for paging messages on the PO. In satellite systems, network devices notify the UE of paging resource configuration parameters through system information, and the paging occasion for each band position is pre-configured. In order to receive paging messages, the UE needs to receive system information on different band positions, resulting in resource waste and increased UE power consumption. Summary of the Invention

[0111] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0112] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0113] The following describes the relevant technologies involved in this disclosure:

[0114] Paging is initiated by the network device. An idle UE receives the paging message and then initiates a random access procedure. The paging process includes paging, the random access procedure, and information exchange with the RRC layer on the serving link. During each Discontinuous Reception (DRX) cycle, the UE needs to listen to one PO to receive the paging message. A PO refers to a set of Physical downlink control channel (PDCCH) listening opportunities and can contain multiple time slots for transmitting downlink control information (DCI). When a portion of the resources in a radio frame is used to transmit paging messages, this radio frame is called a paging frame (PF). Each PF can be configured with a maximum of four POs, for example, through the RRC parameter maxPO-perPF.

[0115] Referring to Figure 1, the base station broadcasts paging messages on the PO. In satellite systems, beam hopping serves the entire satellite coverage area using a hopping method, covering only one band at a time and another band at the next time. Each band under satellite coverage must have a PO, and the POs for different bands are different. For power saving purposes, the terminal only listens for paging messages on its own paging PO.

[0116] The parameters used by the UE to receive paging messages are configured by the system. The system information sent by the network device to the UE includes the following parameters:

[0117] Default paging cycle;

[0118] n and paging frame offset (nAndPagingFrameOffset): n is the number of paging frames;

[0119] ns: This refers to the number of paging opportunities in each paging frame;

[0120] The first PDCCH monitoring occupancy of a PO (firstPDCCH-MonitoringOccasionOfPO) refers to the first PDCCH monitoring occupancy of each paging occupancy, such as the starting position of the paging occupancy.

[0121] The UE can calculate its own paging timing based on parameters such as paging period, number of paging frames, paging frame offset, number of paging opportunities contained in the paging frame, and paging opportunity start position.

[0122] In beam-hopping scenarios, due to satellite movement, the beam position covering the UE changes. Therefore, the UE will not remain on a single beam position indefinitely, but will only stay on each beam position for a limited time. Considering that the paging timing for each beam position is pre-configured and different for each, the time the UE is on a particular beam position may not include the paging timing configured for that beam position by the network device. This means that when the network device sends a paging message on that beam position, the UE is not covered by that beam. If the UE receives system information during the time it is on a beam position, but the network device does not send a paging message during that time, paging will fail. In other words, the terminal ineffectively receives system information, wasting computing resources and increasing UE power consumption.

[0123] This disclosure provides a paging monitoring method, a terminal, a network device, and a processor-readable storage medium to address the problems of resource waste and increased power consumption of UEs in current methods for monitoring paging messages on satellite coverage. The method and terminal (or network device) are based on the same concept. Since the methods and terminals (or network devices) solve problems in a similar manner, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0124] As shown in Figure 2, an embodiment of this disclosure provides a paging monitoring method, including the following steps:

[0125] Step 21: The terminal receives a first message sent by the network device; wherein the first message carries wavelet-related information of at least one wavelet under satellite coverage, and the wavelet is a wavelet in which the terminal can receive paging messages.

[0126] In some embodiments, a satellite may cover multiple wavelengths, and a terminal may be located within one or more of these wavelengths. The terminal may receive a paging message within these wavelengths, or it may not be able to receive a paging message. In this embodiment, the first message sent by the network device to the terminal carries wavelength-related information of at least one wavelength where the terminal can receive paging messages.

[0127] For example, the network device determines which or more wavelengths under satellite coverage can support a terminal receiving a paging message, and notifies the terminal of the wavelength-related information of at least one wavelength on which the terminal can receive the paging message. In some embodiments, if the terminal can receive multiple wavelengths, the network device may notify the terminal of the wavelength-related information of multiple wavelengths on which it can receive the paging message in the form of a list, etc., but this embodiment of the present disclosure is not limited thereto.

[0128] Step 22: The terminal performs paging message listening based on the wave position related information.

[0129] In this embodiment, the network device can notify the terminal of the wavelength information of at least one wavelength on which it can receive paging messages. In this way, the terminal can perform paging message listening based on the wavelength information, which can ensure that the terminal can accurately receive paging messages and avoid the terminal having to receive system information on different wavelengths, which would cause resource waste and increase terminal power consumption.

[0130] In some embodiments, the wave position related information includes one of the following:

[0131] The wave position covers the time-related information of the terminal;

[0132] The identification information of the wave position and the time-related information of the wave position covering the terminal.

[0133] For example, the wave position related information includes time-related information of the wave position covering the terminal. That is, the network device notifies the terminal that it can receive paging messages in at least one wave position, and the time-related information of each wave position covering the terminal. Thus, the terminal can perform paging message listening based on the time it is in the wave position, ensuring that the terminal can accurately receive paging messages and avoiding the need for the terminal to receive system information in different wave positions, which would cause resource waste and increase terminal power consumption.

[0134] For another example, the wave position related information includes the wave position's identification information (e.g., wave position index or number) and the time-related information of the wave position covering the terminal. That is, the network device notifies the terminal which wave position(s) can receive paging messages, and notifies the terminal of the time-related information of each wave position covering the terminal. Thus, the terminal can know which wave position can receive paging messages, and perform paging message listening based on the time the terminal is in that wave position, ensuring that the terminal can accurately receive paging messages, avoiding the need for the terminal to receive system information in different wave positions, which would cause resource waste and increase terminal power consumption.

[0135] In some embodiments, the time-related information includes one of the following:

[0136] The wave position covers the start time of the terminal and the end time of the wave position covering the terminal;

[0137] The wavelength covers the terminal at the start time and for the duration of the wavelength coverage.

[0138] For example, the start time when the wave position covers the terminal can also be referred to as the start time when the wave position provides services to the terminal, or the time when the terminal enters the wave position, etc. The end time when the wave position covers the terminal can also be referred to as the end time when the wave position provides services to the terminal, or the time when the terminal leaves the wave position, etc., and the embodiments disclosed herein are not limited thereto.

[0139] For example, the time-related information includes the start time of the wavelength covering the terminal and the end time of the wavelength covering the terminal. Thus, when the terminal knows that the wavelength covering which it can receive paging messages covers both the start and end times of the coverage, it can perform paging message listening within the time range from the start to the end of the wavelength coverage. This ensures that the terminal can accurately receive paging messages and avoids the terminal needing to receive system information on different wavelengths, which would waste resources and increase terminal power consumption.

[0140] For example, the time-related information includes: the start time when the wavelength covers the terminal, and the duration of the wavelength coverage. Thus, when the terminal knows the start time and total duration of the wavelength covering it to receive paging messages, it can start listening for paging messages from the beginning of the wavelength coverage and continue listening for the total duration of the coverage. This ensures the terminal can accurately receive paging messages and avoids the need for the terminal to receive system information on different wavelengths, thus preventing resource waste and increased power consumption.

[0141] For example, the time-related information includes the start time when the wavelength covers the terminal. Thus, when the terminal learns that a wavelength covering its paging message coverage begins at that start time, it can begin listening for paging messages from that start time. Furthermore, because the network device notifies the terminal of the wavelength-related information for at least one wavelength on which it can receive paging messages, meaning the terminal can accurately receive paging messages on that wavelength, this avoids the terminal needing to receive system information on different wavelengths, thus preventing resource waste and increased power consumption.

[0142] In some embodiments, the terminal receives a first message sent by the network device, including at least one of the following:

[0143] Method 1: The terminal receives an RRC reconfiguration message sent by the network device; wherein the RRC reconfiguration message carries the waveform-related information.

[0144] For example, when a terminal initiates an RRC connection establishment process and enters the connected state, the network device can use the RRCReconfiguration message to notify the terminal in the connected state of at least one wavelength-related information of the wavelength at which it can receive paging messages.

[0145] Method 2: The terminal receives a downlink information transmission message sent by the network device; wherein the downlink information transmission message carries the waveform-related information.

[0146] For example, when a terminal initiates an RRC connection establishment process and enters the connected state, the network device can use downlink information transfer (DLInformationTransfer) messages to notify the terminal in the connected state of at least one wavelength of the wavelength for which it can receive paging messages.

[0147] Method 3: The terminal receives an RRC release message sent by the network device; wherein the RRC release message carries the waveform-related information.

[0148] For example: The core network sends a UE context release request message to the base station (i.e., the network device). The base station sends a UE context release complete message to the core network, and through an RRC release (RRCRelease) message, notifies the terminal of the wavelet-related information of at least one wavelet that it can receive paging messages when the connection is released.

[0149] In some embodiments, the terminal performs paging message listening based on the wave position related information, including:

[0150] The terminal determines a first wave position from the at least one wave position based on the wave position related information;

[0151] The terminal starts paging message listening from the beginning of the first wave position covering the terminal, and / or stops paging message listening at the end of the first wave position covering the terminal.

[0152] For example, when a terminal receives wavelet-related information from a network device indicating that the terminal can receive at least one wavelet of a paging message, the terminal can select a time period based on the wavelet-related information (e.g., a time period to cover the terminal determined by the terminal based on the time-related information in the wavelet-related information, or the start and end times to cover the terminal), and the wavelet corresponding to that time period is the first wavelet.

[0153] For example, the terminal begins paging message listening from the start time the first wave position covers it. This could be the time range from the start to the end of the first wave position's coverage, or the duration of the first wave position's coverage. Specifically, starting from the start time the first wave position covers it, the terminal searches for a Synchronization Signal Block (SSB) and receives system information. Based on the system information, it calculates the paging timing and receives the paging message at the calculated timing. This way, because the network device notifies the terminal of wave position information relevant to at least one wave position where it can receive the paging message—meaning the terminal can accurately receive the paging message on that wave position—it avoids the terminal needing to receive system information on different wave positions, thus preventing resource waste and increased power consumption.

[0154] For example, the terminal does not perform paging message listening after the end time of the first wave position covering the terminal, or after the duration of the first wave position covering the terminal. This way, since the terminal leaves the first wave position after the end time or after the duration, the terminal does not perform the paging message listening process, thus reducing terminal power consumption.

[0155] For example, the terminal starts listening for paging messages from the beginning of the first wave position covering the terminal, and stops listening for paging messages after the end of the first wave position covering the terminal (or after the duration of the first wave position covering the terminal). In this way, since the network device notifies the terminal of wave position information related to at least one wave position where it can receive paging messages, meaning the terminal can accurately receive paging messages on that wave position, it avoids the terminal needing to receive system information on different wave positions, thus preventing resource waste and increased terminal power consumption. Furthermore, since the terminal leaves the first wave position after the end of the first wave position or after the duration of the first wave position (i.e., the first wave position no longer covers the terminal), the terminal does not perform the paging message listening process, thereby reducing terminal power consumption.

[0156] In some embodiments, before the terminal receives the first message sent by the network device, the method further includes:

[0157] The terminal sends a second message to the network device; wherein the second message carries the location information of the terminal, and the wave position related information is determined based on the location information of the terminal.

[0158] For example, considering factors such as satellite movement, a terminal might fail to receive paging messages after receiving system information on one or more wavelengths, resulting in invalid system information reception. These wavelengths are referred to as wavelengths where paging messages cannot be received. To ensure effective reception of system information and accurate reception of paging messages, network devices can control the terminal to avoid receiving system information on these wavelengths where paging messages cannot be received, thus preventing it from listening for paging messages on these wavelengths. Since satellites move along specific orbits, network devices, knowing the terminal's location information, can predict the terminal's trajectory within the satellite's coverage area based on the terminal's location information during satellite movement. The wavelengths this trajectory passes through and the time spent on each wavelength (e.g., the time the terminal enters each wavelength, the time the terminal leaves each wavelength, and the duration the terminal stays on each wavelength) can also be predicted. Network devices can compare the time a terminal spends in each band with the paging period configured for that band. If the terminal's stay in a band is less than the corresponding paging period, there's a possibility the terminal won't receive a paging message during that time. If the terminal's stay in a band is greater than or equal to the corresponding paging period, then the terminal will receive at least one paging message during that time. This allows the network device to determine the band information for at least one band where the terminal can receive paging messages. Alternatively, the ability to receive a paging message can be determined by whether the band coverage time includes the terminal's corresponding paging timing. If the band coverage time includes the terminal's corresponding paging timing, then the terminal can receive a paging message in that band.

[0159] The terminals disclosed in this embodiment can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminals may differ in different systems; for example, in a 5G system, a terminal may be called User Equipment (UE). Wireless terminals can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminals can be mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal may also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments disclosed herein.

[0160] As shown in Figure 3, an embodiment of this disclosure provides a paging monitoring method, including the following steps:

[0161] Step 31: The network device sends a first message to the terminal; wherein the first message carries wavelet-related information of at least one wavelet under satellite coverage, and the wavelet is the wavelet in which the terminal can receive paging messages.

[0162] In some embodiments, a satellite may cover multiple wavelengths, and a terminal may be located within one or more of these wavelengths. The terminal may receive a paging message within these wavelengths, or it may not be able to receive a paging message. In this embodiment, the first message sent by the network device to the terminal carries wavelength-related information of at least one wavelength where the terminal can receive paging messages.

[0163] For example, the network device determines which or more wavelengths under satellite coverage can support a terminal receiving a paging message, and notifies the terminal of the wavelength-related information of at least one wavelength on which the terminal can receive the paging message. In some embodiments, if the terminal can receive multiple wavelengths, the network device may notify the terminal of the wavelength-related information of multiple wavelengths on which it can receive the paging message in the form of a list, etc., but this embodiment of the present disclosure is not limited thereto.

[0164] In this embodiment, the network device can notify the terminal of the wavelength information of at least one wavelength on which it can receive paging messages. In this way, the terminal can perform paging message listening based on the wavelength information, which can ensure that the terminal can accurately receive paging messages and avoid the terminal having to receive system information on different wavelengths, which would cause resource waste and increase terminal power consumption.

[0165] In some embodiments, the wave position related information includes one of the following:

[0166] The wave position covers the time-related information of the terminal;

[0167] The identification information of the wave position and the time-related information of the wave position covering the terminal.

[0168] For example, the wave position related information includes time-related information of the wave position covering the terminal. That is, the network device notifies the terminal that it can receive paging messages in at least one wave position, and the time-related information of each wave position covering the terminal. Thus, the terminal can perform paging message listening based on the time it is in the wave position, ensuring that the terminal can accurately receive paging messages and avoiding the need for the terminal to receive system information in different wave positions, which would cause resource waste and increase terminal power consumption.

[0169] For another example, the wave position related information includes the wave position's identification information (e.g., wave position index or number) and the time-related information of the wave position covering the terminal. That is, the network device notifies the terminal which wave position(s) can receive paging messages, and notifies the terminal of the time-related information of each wave position covering the terminal. Thus, the terminal can know which wave position can receive paging messages, and perform paging message listening based on the time the terminal is in that wave position, ensuring that the terminal can accurately receive paging messages, avoiding the need for the terminal to receive system information in different wave positions, which would cause resource waste and increase terminal power consumption.

[0170] In some embodiments, the time-related information includes one of the following:

[0171] The wave position covers the start time of the terminal and the end time of the wave position covering the terminal;

[0172] The wavelength covers the terminal at the start time and for the duration of the wavelength coverage.

[0173] For example, the start time when the wave position covers the terminal can also be referred to as the start time when the wave position provides services to the terminal, or the time when the terminal enters the wave position, etc. The end time when the wave position covers the terminal can also be referred to as the end time when the wave position provides services to the terminal, or the time when the terminal leaves the wave position, etc., and the embodiments disclosed herein are not limited thereto.

[0174] For example, the time-related information includes the start time of the wavelength covering the terminal and the end time of the wavelength covering the terminal. Thus, when the terminal knows that the wavelength covering which it can receive paging messages covers both the start and end times of the coverage, it can perform paging message listening within the time range from the start to the end of the wavelength coverage. This ensures that the terminal can accurately receive paging messages and avoids the terminal needing to receive system information on different wavelengths, which would waste resources and increase terminal power consumption.

[0175] For example, the time-related information includes: the start time when the wavelength covers the terminal, and the duration of the wavelength coverage. Thus, when the terminal knows the start time and total duration of the wavelength covering it to receive paging messages, it can start listening for paging messages from the beginning of the wavelength coverage and continue listening for the total duration of the coverage. This ensures the terminal can accurately receive paging messages and avoids the need for the terminal to receive system information on different wavelengths, thus preventing resource waste and increased power consumption.

[0176] For example, the time-related information includes the start time when the wavelength covers the terminal. Thus, when the terminal learns that a wavelength covering its paging message coverage begins at that start time, it can begin listening for paging messages from that start time. Furthermore, because the network device notifies the terminal of the wavelength-related information for at least one wavelength on which it can receive paging messages, meaning the terminal can accurately receive paging messages on that wavelength, this avoids the terminal needing to receive system information on different wavelengths, thus preventing resource waste and increased power consumption.

[0177] In some embodiments, the terminal receives a first message sent by the network device, including at least one of the following:

[0178] Method 1: The terminal receives an RRC reconfiguration message sent by the network device; wherein the RRC reconfiguration message carries the waveform-related information.

[0179] For example, when a terminal initiates an RRC connection establishment process and enters the connected state, the network device can use the RRCReconfiguration message to notify the terminal in the connected state of at least one wavelength-related information of the wavelength at which it can receive paging messages.

[0180] Method 2: The terminal receives a downlink information transmission message sent by the network device; wherein the downlink information transmission message carries the waveform-related information.

[0181] For example, when a terminal initiates an RRC connection establishment process and enters the connected state, the network device can use downlink information transfer (DLInformationTransfer) messages to notify the terminal in the connected state of at least one wavelength of the wavelength for which it can receive paging messages.

[0182] Method 3: The terminal receives an RRC release message sent by the network device; wherein the RRC release message carries the waveform-related information.

[0183] For example: The core network sends a UE context release request message to the base station (i.e., the network device). The base station sends a UE context release complete message to the core network, and through an RRC release (RRCRelease) message, notifies the terminal of the wavelet-related information of at least one wavelet that it can receive paging messages when the connection is released.

[0184] In some embodiments, before the network device sends the first message to the terminal, it further includes:

[0185] The network device receives a second message sent by the terminal; wherein the second message carries the location information of the terminal;

[0186] The network device determines the wave position related information based on the location information of the terminal.

[0187] In some embodiments, the network device determines that the terminal can receive at least one wavelength of a paging message by:

[0188] The network device determines the time-related information of each wavelength under satellite coverage covering the terminal based on the terminal's location information;

[0189] The network device determines at least one wavelength from which the terminal can receive paging messages based on the time-related information of each wavelength covered by the satellite and the paging cycle or paging timing corresponding to each wavelength covered by the satellite.

[0190] For example, considering factors such as satellite movement, a terminal might fail to receive paging messages after receiving system information on one or more wavelengths, resulting in invalid system information reception. These wavelengths are referred to as wavelengths where paging messages cannot be received. To ensure effective reception of system information and accurate reception of paging messages, network devices can control the terminal to avoid receiving system information on these wavelengths where paging messages cannot be received, thus preventing it from listening for paging messages on these wavelengths. Since satellites move along specific orbits, network devices, knowing the terminal's location information, can predict the terminal's trajectory within the satellite's coverage area based on the satellite's location information during satellite movement. The wavelengths this trajectory passes through, and the time the terminal spends on each wavelength (e.g., the time the terminal enters each wavelength, the time the terminal leaves each wavelength, and the duration the terminal stays on each wavelength), can also be predicted. In this way, network devices can determine the wavelength-related information for at least one wavelength where the terminal can receive paging messages, based on the predicted wavelengths the terminal's trajectory passes through within the satellite's coverage area and the time spent on each wavelength.

[0191] In some embodiments, the network device determines at least one wavelength from which the terminal can receive paging messages based on time-related information about each wavelength covered by the satellite and the paging cycle or paging timing corresponding to each wavelength covered by the satellite, including:

[0192] The network device obtains the duration or time range of coverage of the terminal by each wavelength based on the time-related information of each wavelength covering the terminal under satellite coverage.

[0193] The network device determines the wave position that covers the terminal with a duration greater than or equal to the paging period as the wave position in which the terminal can receive the paging message; or the network device determines the wave position that covers the terminal with a time range that includes the paging timing corresponding to the terminal as the wave position in which the terminal can receive the paging message.

[0194] For example, network devices can compare the time a terminal spends in each band with the paging period configured for each band. If the time a terminal spends in a certain band is less than the paging period corresponding to that band, then there is a certain possibility that the terminal will not receive a paging message during the time it spends in that band. If the time a terminal spends in a certain band is greater than or equal to the paging period corresponding to that band, then the terminal can receive at least one paging message during the time it spends in that band. In this way, the network device can determine the band-related information of at least one band in which the terminal can receive paging messages.

[0195] For example, network devices can compare the time range in which a terminal is located within each wavelength with the corresponding paging opportunity. If the time range in which the terminal stays within a certain wavelength does not include the corresponding paging opportunity, then the terminal cannot receive a paging message within the time range in which it stays within that wavelength. If the time range in which the terminal stays within a certain wavelength includes the corresponding paging opportunity, then the terminal can receive at least one paging message within the time range in which it stays within that wavelength. In this way, the network device can determine the wavelength-related information of at least one wavelength in which the terminal can receive paging messages.

[0196] The network device disclosed in this embodiment may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with a wireless terminal via one or more sectors on the air interface, or other names. The network device may be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network equipment involved in this disclosure can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA) system, a NodeB in a wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in this disclosure. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0197] The paging monitoring method of this disclosure is described below with reference to specific embodiments:

[0198] Example 1: The network device, in the connected state, notifies the UE of the waveform-related information that it can receive paging messages;

[0199] As shown in Figure 4, the specific process includes:

[0200] Step 41: The UE initiates the RRC connection establishment process, enters the connected state, and activates the access stratum (AS) layer security;

[0201] Step 42: The UE reports its geographic location information, i.e., the terminal's location information, via a measurement report message;

[0202] Step 43: The base station sends at least one wavelength-related information of the wavelength at which the paging message can be received to the UE via RRCReconfiguration or DLInformationTransfer messages.

[0203] For example, a base station can predict the trajectory of a terminal within the satellite coverage area based on the terminal's location information reported by the terminal, the wave positions the trajectory passes through and the time spent in each wave position, and further determine the wave position-related information of at least one wave position in which the terminal can receive paging messages.

[0204] In some embodiments, the wave position related information includes one of the following:

[0205] At least one wavelength position covers the time-related information of the terminal;

[0206] The identification information of each wave position in at least one wave position, and the time-related information of each wave position covering the terminal in at least one wave position.

[0207] The time-related information includes the following:

[0208] Each of at least one wave position covers the start time of the terminal, and each of at least one wave position covers the end time of the terminal.

[0209] The start time of each of the at least one wave position covering the terminal, and the duration of each of the at least one wave position covering the terminal.

[0210] Step 44: The UE actively disconnects and enters the idle state;

[0211] Step 45: The UE selects one of the multiple wavebands, prepares to receive SSB and system information at the beginning of the coverage of the terminal on that waveband, calculates the paging timing based on the received system information, and receives the paging message at that paging timing.

[0212] Example 2: When the network device releases the connection, it notifies the UE of the waveform information related to its ability to receive paging messages;

[0213] As shown in Figure 5, the specific process includes:

[0214] Step 51: The UE initiates the RRC connection establishment process, enters the connection state, and activates AS layer security;

[0215] Step 52: The UE reports its geographic location information, i.e., the terminal's location information, via a measurement report message;

[0216] Step 53: The core network sends a UE context release request message to the base station;

[0217] Step 54: The base station sends a UE context release complete message to the core network;

[0218] Step 55: The base station sends an RRC release message to the UE, carrying wavelet-related information of at least one wavelet that the terminal can receive paging messages.

[0219] For example, a base station can predict the trajectory of a terminal within the satellite coverage area based on the terminal's location information reported by the terminal, the wave positions the trajectory passes through and the time spent in each wave position, and further determine the wave position-related information of at least one wave position in which the terminal can receive paging messages.

[0220] In some embodiments, the wave position related information includes one of the following:

[0221] At least one wavelength position covers the time-related information of the terminal;

[0222] The identification information of each wave position in at least one wave position, and the time-related information of each wave position covering the terminal in at least one wave position.

[0223] The time-related information includes the following:

[0224] Each of at least one wave position covers the start time of the terminal, and each of at least one wave position covers the end time of the terminal.

[0225] The start time of each of the at least one wave position covering the terminal, and the duration of each of the at least one wave position covering the terminal.

[0226] Step 56: After receiving the RRC release message, the UE enters the idle state;

[0227] Step 57: The UE selects one of the multiple wavebands, prepares to receive SSB and system information at the beginning of the coverage of the terminal by the waveband, calculates the paging timing based on the received system information, and receives the paging message at the paging timing.

[0228] The paging message monitoring method provided in this embodiment can solve the problem that the UE may not receive paging messages in a beam-hopping system. Specifically, the network device notifies the UE of the relevant information of at least one beam position in which the paging message can be received. The UE selects one of the at least one beam positions and performs paging message monitoring within the time range covered by that beam position, ensuring that the UE can receive the paging message within that beam position, and reducing UE power consumption and saving resources.
