Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a paging method, apparatus, and device. Background Technology

[0002] When a network device establishes a connection with a terminal device, the network device needs to page the terminal device at the time the terminal device is paged. When the network device successfully pages the terminal device, the network device and the terminal device establish a connection.

[0003] Currently, the paging time window for a terminal device can be determined using extended discontinuous reception (eDRX), enabling the network device to page the terminal device. For example, both the satellite and the terminal device calculate the paging time window using eDRX, and the satellite can page the terminal device within that window. However, the network device's signal coverage for the terminal device is discontinuous. When the paging time window calculated by the network device based on eDRX falls within a discontinuous coverage period, the network device cannot page the terminal device, resulting in a low success rate for paging the terminal device.

[0116] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0117] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0118] To facilitate understanding, the concepts involved in the embodiments of this application will be explained first.

[0119] Network equipment: A device with wireless transceiver capabilities. This includes, but is not limited to: Evolutionary Node Bs (eNBs or eNodeBs) in Long Term Evolution (LTE), base stations (gNodeBs or gNBs) or TRPs in New Radio (NR) technologies, base stations in Evolution After Next (EER) systems, access nodes, wireless relay nodes, and wireless backhaul nodes in Wireless Fidelity (WiFi) systems. Base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, or balloon stations, satellites, etc. Multiple base stations can support networks using the same technology mentioned above, or they can support networks using different technologies mentioned above. A base station can contain one or more co-located or non-co-located TRPs.

[0120] Terminal equipment: A device with wireless transceiver capabilities. Terminal equipment can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can be deployed in the air (such as on airplanes, balloons, and satellites). The terminal equipment can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal equipment, augmented reality (AR) terminal equipment, wireless terminals in industrial control, vehicle-mounted terminal equipment, wireless terminals in self-driving vehicles, wireless terminal equipment in remote medical care, wireless terminal equipment in smart grids, wireless terminal equipment in transportation safety, wireless terminal equipment in smart cities, wireless terminal equipment in smart homes, wearable terminal equipment, etc. The terminal equipment involved in the embodiments of this application may also be referred to as a terminal, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, wireless communication equipment, UE agent, or UE device, etc. The terminal equipment may also be fixed or mobile.

[0121] Paging Time Window: The paging time window is the paging period for terminal devices. Within the paging time window, network devices can successfully page terminal devices.

[0122] The following is combined Figure 1 The paging time window is explained.

[0123] Figure 1 This is a schematic diagram of a paging time window provided in an embodiment of this application. Please refer to... Figure 1 Within a single period (e.g., a superframe period of 2.91 hours, or 24 hours), there are paging time windows A, B, and C. The starting position of each paging time window within a superframe period can be identified using a specific superframe number and radio frame number, or it can be identified using natural time. For example, the starting position of paging time window A might be the fifth radio frame within the second superframe period, or it could be the starting position of paging time window A at 12:03:20. This process is repeated in the next period.

[0124] In related technologies, terminal devices and network devices can each determine the paging time window of the terminal device using its eDRX. Since the terminal device and network device can obtain the same paging time window, the network device can page the terminal device within the paging time window. For example, the satellite and terminal device calculate the paging time window of the terminal device using its eDRX and identifier, respectively, and the satellite pages the terminal device within the paging time window. However, the signal coverage of the network device for the terminal device is discontinuous. For example, the satellite does not continuously serve the terminal device. If the signal from satellite 1 leaves the terminal device before the signal from satellite 2 begins serving it, then the satellite signal does not serve the terminal device during this period. When the paging time window calculated by the network device and terminal device based on eDRX falls within a discontinuous coverage period, the network device cannot page the terminal device, resulting in a low success rate for paging the terminal device.

[0125] To address the low success rate of paging terminal devices by network devices in existing technologies, this application provides a paging method. A core network device determines at least one eDRX threshold value to classify eDRXs. Based on the network device's service time information for terminal devices, it obtains the start time information of at least one first paging time window corresponding to each eDRX type. The core network device sends the eDRX threshold value information and the start time information of at least one first paging time window corresponding to each eDRX type to the network device. The network device determines the type of the terminal device's eDRX based on the eDRX cycle duration and determines the start time of the terminal device's paging time window based on the eDRX type. The terminal device can obtain the eDRX threshold value information and the start time information of at least one first paging time window corresponding to each eDRX type broadcast by the network device, determine the type of the terminal device's eDRX based on the eDRX cycle duration, and determine the start time information of at least one first paging time window corresponding to the eDRX type. The network device sends a paging message to the terminal device at the start time of the paging time window. In this way, network devices can directly determine the start time of paging time windows for multiple terminal devices based on the eDRX type of the terminal devices, improving the efficiency of network devices in determining paging time windows. Furthermore, since the start time of the paging time window corresponding to the eDRX type is obtained by the core network devices based on the time information of the network devices serving the terminal devices, the paging time window corresponding to the eDRX type must be within the time range of the network devices serving the terminal devices, and the paging time windows of the network devices and the terminal devices are the same. This enables the network devices to accurately page the terminal devices, improving the success rate of paging terminal devices.

[0126] Below, in conjunction with Figure 2The application scenarios of the embodiments of this application will be introduced.

[0127] Figure 2 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. Please refer to [link / reference]. Figure 2 This includes network devices, terminal devices, and core network devices. The core network devices send eDRX threshold information and the start time of the paging time window corresponding to each eDRX type to the network devices. The network devices send eDRX threshold information and the start time, offset step size, and offset quantity of the paging time window corresponding to each eDRX type to the terminal devices. Both the network devices and terminal devices determine the eDRX type and the start times of multiple paging time windows corresponding to each eDRX type using the terminal device's eDRX, and determine the start time of the target paging time window for the terminal device. The network device then paging the terminal device at the start time of the paging time window. Since the start time of the paging time window corresponding to each eDRX type is obtained by the core network devices based on the time information of the network devices serving the terminal devices, the paging time window corresponding to each eDRX type must be within the time range of the network devices serving the terminal devices, and the paging time windows of the network devices and terminal devices are the same. This allows the network devices to accurately paging terminal devices, improving the success rate of paging terminal devices.

[0128] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or similar content will not be repeated in different embodiments.

[0129] Figure 3 This is a schematic flowchart illustrating a paging method provided in an embodiment of this application. Please refer to [link / reference]. Figure 3 The method may include:

[0130] S301. The network device receives threshold information of at least one eDRX sent by the core network device and start time information of at least one first paging time window corresponding to the type of eDRX of the terminal device.

[0131] The execution entity in this application embodiment can be a network device or a paging device installed in the network device. Optionally, the paging device can be implemented by software or by a combination of software and hardware. The eDRX threshold information is used to classify the eDRX of the terminal device. For example, the eDRX threshold information can be values ​​such as 30, 60, and 90. For example, if the eDRX threshold information is 30 seconds, then the eDRX threshold information can divide the eDRX of the terminal device into two categories: one is terminal devices with an eDRX period duration of less than or equal to 30 seconds, and the other is terminal devices with an eDRX period duration of more than 30 seconds.

[0132] Optionally, before the network device receives threshold information for at least one eDRX and start time information for at least one first paging time window corresponding to the type of eDRX of the terminal device, the core network device may determine threshold information for at least one eDRX and start time information for at least one first paging time window corresponding to each type of eDRX.

[0133] Optionally, the core network device can determine at least one eDRX threshold information according to the following feasible implementation: the core network determines at least one eDRX threshold information based on auxiliary information. Optionally, the auxiliary information can be the time information of the network device serving the terminal device. For example, the auxiliary information may include the time when the network device enters the cell, the time when the network device leaves the cell, the duration of the network device serving the terminal device in one cycle, and the ephemeris information of the network device.

[0134] Optionally, the core network device can determine the eDRX threshold information based on the time when the network device enters the cell. For example, if the core network device obtains that network device A enters the cell at time A and leaves the cell at time a, network device B enters the cell at time B and leaves the cell at time b, network device C enters the cell at time C and leaves the cell at time c, and network device D enters the cell at time D and leaves the cell at time d, then the eDRX threshold information that the core network device can determine can also include: the time difference between time A and time B, the time difference between time C and time D, and the time difference between time a and time b and between time d and time c.

[0135] Optionally, the core network equipment can determine the timing information of the first paging time window for each type of eDRX based on the type of eDRX. For example, the starting time of the paging time window for the terminal equipment corresponding to eDRX type 1 is: the time when network devices A, B, and C enter the cell, or a preset time offset of the time when network devices A, B, and C enter the cell. The starting time of the paging time window for the terminal equipment corresponding to eDRX type 2 can be: the time when network devices A, B, and D enter the cell, or a preset time offset of the time when network devices A, B, and D enter the cell.

[0136] After determining at least one eDRX threshold value and the start time information of at least one first paging time window corresponding to each eDRX type, the core network device sends the threshold value information of at least one eDRX and the start time information of at least one first paging time window corresponding to the eDRX type of the terminal device to the network device. For example, after determining the eDRX threshold value information and the start time information corresponding to each eDRX type, the core network device can send the eDRX threshold value information and the start time information of the paging time window corresponding to each eDRX after dividing the eDRX according to the eDRX threshold value information to the network device.

[0137] S302. The network device determines the type of eDRX of the terminal device based on the extended discontinuous reception period of the eDRX of the terminal device.

[0138] Optionally, the network device can determine the type of the terminal device's eDRX according to the following feasible implementation: the network device obtains threshold value information for at least one eDRX used for eDRX classification. Optionally, the network device obtains the threshold value information for at least one eDRX from the core network device. For example, after the core network device determines the threshold value information for at least one eDRX, it can send the threshold value information of the eDRX to the network device.

[0139] The network device determines the type of the terminal device's eDRX based on at least one eDRX threshold value and the eDRX period duration. For example, if the network device obtains an eDRX threshold value of 30 seconds, and the terminal device's eDRX period duration is 20 seconds, then the terminal device's eDRX type is less than 30 seconds; if the terminal device's eDRX period duration is 50 seconds, then the terminal device's eDRX type is greater than 30 seconds. Similarly, if the network device obtains eDRX threshold values ​​of 30 seconds and 60 seconds, and the terminal device's eDRX period duration is 50 seconds, then the terminal device's eDRX type is greater than 30 seconds but less than 60 seconds; if the terminal device's eDRX period duration is 90 seconds, then the terminal device's eDRX type is greater than 60 seconds.

[0140] Optionally, when determining the eDRX threshold information, the network device can determine the number of eDRX types for the terminal device based on the eDRX threshold information. For example, if the network device obtains 1 eDRX threshold information, the terminal device has 2 eDRX types; if the network device obtains 3 eDRX threshold information, the terminal device has 5 eDRX types.

[0141] S303. The network device determines the start time information of the target paging time window of the terminal device corresponding to the type of eDRX.

[0142] Optionally, the start time information of the target paging time window includes the time when the network device serves the terminal device. Optionally, the network device can determine the start time information of the terminal device's paging time window according to the following feasible implementation: the network device obtains the start time information of at least one first paging time window corresponding to the type of the terminal device's eDRX. Optionally, the network device obtains the start time information of at least one first paging time window corresponding to the type of the terminal device's eDRX from the core network device. For example, after the core network device determines the start time information of at least one first paging time window corresponding to each type of eDRX, the core network device can send the start time information of at least one first paging time window corresponding to each type of eDRX to the network device. The network device determines the start time information of the target paging time window of the terminal device based on the first information and the start time information of the first paging time window. Optionally, the first information may include at least one of the following: offset quantity, offset step size, and the identifier of the terminal device.

[0143] Optionally, the offset amount is the number of times that the paging time windows of terminal devices with the same first paging time window start time can be offset within the coverage service time range of the network device. For example, if the network device determines the start time information of the first paging time window of a terminal device as time A based on the eDRX type of the terminal device, and the start time of the paging time windows of terminal devices B and C is the same as the start time of the first paging time window of terminal device A, and the paging time windows of terminal devices B and C can be offset within the time period during which the network device serves the terminal devices, then the offset amount is 3.

[0144] The offset step size is the time interval for each offset. For example, when the network device offsets the start time of the paging time window for terminal device A and terminal device B, if the offset step size is 10 seconds, then the start time of the paging time window for terminal device A will be offset 10 seconds to the right, and the start time of the paging time window for terminal device B will be offset 20 seconds to the right. The identifier of the terminal device can be the UE-ID of the terminal device. In this way, when the start time of the paging time windows of multiple terminal devices is the same, the network device can adjust the paging time windows of the terminal devices, thereby avoiding paging multiple terminal devices at the same time, thus saving communication resources and improving the paging success rate.

[0145] Optionally, the network device determines the start time information of the target paging time window of the terminal device based on the first information and the start time information of the first paging time window.

[0146] Below, in conjunction with Figure 4The process of offsetting the start time of the paging time window is explained.

[0147] Figure 4 This is a schematic diagram illustrating a process of offsetting the start time, as provided in an embodiment of this application. Please refer to... Figure 4 This includes the coverage duration of the network device to the terminal device and the paging time window A. The preset offset duration is the offset duration pre-set by the network device, and the maximum executable offset is the maximum offset that the paging time window A can make within the coverage duration of the network device to the terminal device. Within the maximum offset range, the start time of the paging time window A can be shifted, thus causing the paging time window to shift.

[0148] S304. The network device sends a paging message to the terminal device based on the start time information of the target paging time window.

[0149] Optionally, after determining the start time information of the target paging time window, the network device can determine the start time of multiple target paging time windows (the time when the network device serves the terminal device). The network device can send a paging message to the terminal device at the start time of the target paging time window.

[0150] The following is a detailed explanation of the contents of step S301.

[0151] Optionally, in step S301, the core network device can determine at least one eDRX threshold value. For example, the core network device can determine one eDRX threshold value to classify the eDRX type of the terminal device into two categories, or the core network device can determine two eDRX threshold values ​​to classify the eDRX type of the terminal device into three categories.

[0152] Optionally, in step S301, the auxiliary information may include the time when the network device enters the cell, the time when the network device leaves the cell, the duration of the network device's service to the terminal device in one cycle, and the ephemeris information of the network device.

[0153] The time when a network device enters a cell is the time when the network device begins serving the terminal device. Optionally, there can be multiple network devices. For example, if network device A begins serving the cell where the terminal device is located at time A, and network device B begins serving the cell where the terminal device is located at time B, then the times when the network devices enter the cell are time A and time B.

[0154] The time when a network device leaves the cell is the time when the network device stops serving the terminal device. For example, if network device A stops serving the cell where the terminal device is located at time A, and network device B stops serving the cell where the terminal device is located at time B, then the times when the network devices leave the cell are time A and time B.

[0155] The duration of a network device's service to a terminal device in one cycle can be defined as the continuous duration the network device remains within the cell where the terminal device is located. For example, if the network device enters the cell at time A and leaves the cell at time B, then the duration of the network device's service to the terminal device in one cycle is the time difference between time B and time A. The ephemeris information of a network device can be ephemeris data. For example, the ephemeris information of a network device can be satellite ephemeris data (ephemeris tables).

[0156] Optionally, in step S301, the core network device can determine the start time information of at least one first paging time window corresponding to each type of eDRX. The paging time window is the period during which the terminal device can receive paging messages. For example, a satellite can page the terminal device within the paging time window period.

[0157] Optionally, in step S301, the start time information of the first paging time window includes at least one of the following: the start time of the network device serving the terminal device, and the time offset time corresponding to the start time of the network device serving the terminal device. The start time of the network device serving the terminal device can be the time when the network device enters the cell. For example, if the time when the network device enters the cell is time A, then the start time of the network device serving the terminal device is time A. The time offset time of the start time of the network device serving the terminal device can be the time after time offsetting the start time. For example, in practical applications, an offset duration can be preset. When the network device presets an offset duration, if the start time of the network device serving the terminal device is time A, and the offset duration is a rightward offset time period A, then the time offset time of the network device's start time is the time after time A is offset to the right by time period A.

[0158] The following is a detailed explanation of the contents of step S304.

[0159] Optionally, in step S304, the network device may preset the offset quantity and offset step size. Optionally, when the network device sets the offset quantity and offset step size, the offset quantity and offset step size satisfy the following two conditions: (1) The offset quantity is less than the ratio of the duration of the network device serving the terminal device to a preset time period. Optionally, the preset time period can be a periodic duration or the duration of a wireless frame, etc. (2) The sum of the product of the offset quantity and the offset step size and the window length of the first paging time window is less than the duration of the network device serving the terminal device. Optionally, the window length of the first paging time window is the duration of the first paging time window. For example, if the start time of the first paging time window is time A and the end time is time B, then the window length of the first paging time window is the time period between time B and time A.

[0160] Optionally, in step S304, the network device may obtain the start time information of at least one first paging time window according to the following feasible implementation: obtaining a first preset relationship. The first preset relationship includes at least one eDRX type and the start time information of the first paging time window corresponding to each eDRX type. For example, the first preset relationship may be as shown in Table 1:

[0161] Table 1

[0162] eDRX type Paging Time Window Type 1 Paging Time Window Set 1 Type 2 Paging Time Window Set 2 Type 3 Paging Time Window Set 3 …… ……

[0163] It should be noted that Table 1 is only an example to illustrate the first preset relationship, and is not a limitation on the first preset relationship.

[0164] Based on the type of the terminal device's eDRX and a first preset relationship, the start time information of at least one first paging time window corresponding to the type of the terminal device's eDRX is determined. For example, if the type of the terminal device's eDRX is type 1, then the first paging time window corresponding to the terminal device is paging time window set 1; if the type of the terminal device's eDRX is type 2, then the first paging time window corresponding to the terminal device is paging time window set 2; if the type of the terminal device's eDRX is type 3, then the first paging time window corresponding to the terminal device is paging time window set 3.

[0165] Optionally, in step S304, the network device determines the start time information of the target paging time window of the terminal device based on the first information and the start time information of the first paging time window, which can be one of the following two cases:

[0166] Scenario 1: The start time information of the first paging time window is the start time of the network device serving the terminal device. Optionally, when the start time information of the first paging time window is the start time of the network device serving the terminal device, the network device can determine the start time information of the target paging time window based on the start time of the network device serving the terminal device, the terminal device's identifier, the offset quantity, and the offset step size. Optionally, in this case, the network device can determine the start time information of the target paging time window according to the following formula:

[0167] PTW start =t0+{(UE-ID)mod N}×interval

[0168] Among them, PTW start The information provided is the start time of the target paging time window. t0 is the start time when the satellite begins to enter the serving cell, which is also the start time of the terminal's first paging time window. UE-ID is the identifier of the terminal device, N is the offset number, and interval is the offset step size.

[0169] Case 2: The start time information of the first paging time window is the time offset time corresponding to the start time of the network device serving the terminal device.

[0170] Optionally, when the start time information of the first paging time window is the time offset time corresponding to the start time of the network device serving the terminal device, the network device can determine the start time information of the target paging time window based on the start time of the network device serving the terminal device, the time offset time, the identifier of the terminal device, the offset quantity, and the offset step size. Optionally, in this case, the network device can determine the start time information of the target paging time window according to the following formula:

[0171] PTW start =t0+offset+{(UE-ID)mod N}×interval

[0172] Among them, PTW start The information provided is the start time of the target paging time window, where t0 is the start time when the satellite begins to enter the serving cell, offset is the time offset, t0+offset is the start time of the first paging time window of the terminal, UE-ID is the identifier of the terminal device, N is the number of offsets, and interval is the offset step size.

[0173] This application provides a paging method in which a core network device determines threshold information for at least one eDRX and start time information for at least one first paging time window corresponding to each type of eDRX. The core network device sends the threshold information for at least one eDRX and the start time information for at least one first paging time window corresponding to the type of eDRX of the terminal device to a network device. The network device determines the type of eDRX of the terminal device based on the extended discontinuous reception period of the eDRX of the terminal device. The network device determines the start time of the target paging time window of the terminal device corresponding to the type of eDRX. The network device sends a paging message to the terminal device at the start time of the target paging time window. According to the above method, network devices can directly determine the start time of paging time windows for multiple terminal devices based on the eDRX type of the terminal devices, thereby improving the efficiency of network devices in determining paging time windows. Furthermore, since the start time of the paging time window corresponding to the eDRX type is obtained by the core network device based on the time information of the network device serving the terminal devices, the paging time window corresponding to the eDRX type must be within the time range of the network device serving the terminal devices, and the paging time windows of the network device and the terminal devices are the same. This enables the network device to accurately page the terminal devices, thereby improving the success rate of the network device paging the terminal devices.

[0174] exist Figure 3 Based on the embodiments shown, the following, in conjunction with Figure 5 This application provides a detailed description of another paging method according to an embodiment of the present application.

[0175] Figure 5 This is a flowchart illustrating another paging method provided in an embodiment of this application. Please refer to... Figure 5 The method process includes:

[0176] S501, The terminal device receives the threshold value information of at least one eDRX, the start time information of at least one first paging time window corresponding to each type of eDRX, the offset quantity and the offset step size broadcast by the network device.

[0177] The execution entity in this application embodiment can be a terminal device or a paging device installed in the terminal device. The paging device can be implemented through software, or it can be implemented through a combination of software and hardware.

[0178] Optionally, the network device can obtain at least one eDRX threshold information and at least one first paging time window start time information corresponding to each eDRX type from the core network device, and broadcast the at least one eDRX threshold information and at least one first paging time window start time information corresponding to each eDRX type to the terminal device. For example, the terminal device obtains the start time information of at least one first paging time window corresponding to the eDRX type of the terminal device from the network device by receiving a broadcast.

[0179] Optionally, the start time information of the first paging time window includes at least one of the following: the start time of the network device serving the terminal device, and the time offset time corresponding to the start time of the network device serving the terminal device. The start time of the network device serving the terminal device can be the time when the network device enters the cell. For example, if the time when the network device enters the cell is time A, then the start time of the network device serving the terminal device is time A. The time offset time of the start time of the network device serving the terminal device can be the time after time offsetting the start time. For example, in practical applications, an offset duration can be preset. When the network device presets an offset duration, if the start time of the network device serving the terminal device is time A, and the offset duration is a rightward offset time period A, then the time offset time of the network device's start time is the time after time A is shifted rightward by time period A.

[0180] Network devices can also broadcast the offset quantity and offset step size to terminal devices. This allows the network device to broadcast eDRX threshold information, the start time information of at least one first paging time window corresponding to each eDRX type, the offset quantity, and the offset step size to the terminal device without establishing a connection. This ensures that the start time information of the target paging time window determined by the network device and the terminal device are the same, thereby improving the success rate of paging the terminal device by the network device.

[0181] S502. The terminal device determines the type of eDRX based on the period duration of the extended discontinuous reception eDRX of the terminal device.

[0182] Optionally, the terminal device acquires threshold information for at least one eDRX used for eDRX classification. For example, the terminal device can acquire the threshold information for at least one eDRX from the network device by receiving a broadcast from the network device. The terminal device determines the type of its eDRX based on the threshold information of the at least one eDRX and the period duration of the eDRX. For example, if the threshold information of the eDRX acquired by the terminal device is 30 seconds, and the period duration of the terminal device's eDRX is 20 seconds, then the type of the terminal device's eDRX is less than 30 seconds; if the period duration of the terminal device's eDRX is 50 seconds, then the type of the terminal device's eDRX is greater than 30 seconds.

[0183] S503. The terminal device determines the start time information of the target paging time window of the terminal device corresponding to the type of eDRX.

[0184] Optionally, the start time information of the target paging time window includes the time when the network device serves the terminal device. Optionally, the start time of the target paging time window of the terminal device is determined by the core network device based on the time information of the network device serving the terminal device.

[0185] Optionally, the terminal device can determine the start time information of the target paging time window through the following feasible implementation: the terminal device obtains the start time information of at least one first paging time window corresponding to the type of the terminal device's eDRX. Optionally, the method by which the terminal device obtains the start time information of at least one first paging time window corresponding to the type of the eDRX is the same as the method by which the network device obtains the start time information of at least one first paging time window corresponding to the type of the eDRX, and will not be described in detail in this embodiment.

[0186] The terminal device determines the start time information of its target paging time window based on the first information and the start time information of the first paging time window. The first information includes at least one of the following: offset quantity, offset step size, and terminal device identifier. The offset quantity is the number of times the paging time window can be offset for terminals with the same start time of the first paging time window within the satellite's coverage service time range. The offset step size is the time period for each offset. The terminal device identifier can be the terminal device's UE-ID. In this way, when the start times of the paging time windows of multiple terminal devices are the same, the network device can adjust the paging time windows of the terminal devices, thereby avoiding paging multiple terminal devices at the same time, saving communication resources, and improving the paging success rate.

[0187] Optionally, the offset quantity and offset step size obtained by the terminal device through the network device broadcast must meet the following two conditions: (1) The offset quantity is less than the ratio of the duration of the network device serving the terminal device to the preset time period. Optionally, the preset time period can be the duration of a period or the duration of a wireless frame, etc. (2) The sum of the product of the offset quantity and the offset step size and the window length of the first paging time window is less than the duration of the network device serving the terminal device.

[0188] Optionally, based on the first information and the start time information of the first paging time window, the start time information of the target paging time window of the terminal device is determined, in the following two cases:

[0189] Case 1: The start time information of the first paging time window is the start time of the network device serving the terminal device.

[0190] Optionally, when the start time information of the first paging time window is the start time of the network device serving the terminal device, the terminal device can determine the start time information of the target paging time window based on the start time of the network device serving the terminal device, the terminal device's identifier, the offset quantity, and the offset step size. Optionally, in this case, the terminal device can determine the start time information of the target paging time window according to the following formula:

[0191] PTW start =t0+{(UE-ID)mod N}×interval

[0192] Among them, PTW start The information provided is the start time of the target paging time window. t0 is the start time when the satellite begins to enter the serving cell, which is also the start time of the terminal's first paging time window. UE-ID is the identifier of the terminal device, N is the offset number, and interval is the offset step size.

[0193] Case 2: The start time information of the first paging time window is the time offset time corresponding to the start time of the network device serving the terminal device.

[0194] Optionally, when the start time information of the first paging time window is the time offset time corresponding to the start time of the network device serving the terminal device, the terminal device can determine the start time information of the target paging time window based on the start time of the network device serving the terminal device, the time offset time, the terminal device's identifier, the offset quantity, and the offset step size. Optionally, in this case, the terminal device can determine the start time information of the target paging time window according to the following formula:

[0195] PTW start =t0+offset+{(UE-ID)mod N}×interval

[0196] Among them, PTW start The information provided is the start time of the target paging time window, where t0 is the start time when the satellite begins to enter the serving cell, offset is the time offset, t0+offset is the start time of the first paging time window of the terminal, UE-ID is the identifier of the terminal device, N is the number of offsets, and interval is the offset step size.

[0197] S504. The terminal device receives the paging message sent by the network device based on the start time information of the target paging time window.

[0198] Optionally, after determining the start time information of the target paging time window, the terminal device can determine the start time of multiple target paging time windows (the time when the network device serves the terminal device). The terminal device can receive the paging message sent by the network device at the start time of the target paging time window.

[0199] This application provides a paging method in which a network device broadcasts to a terminal device at least one eDRX threshold value, the start time information of at least one first paging time window corresponding to each eDRX type, the offset quantity, and the offset step size. The terminal device determines the type of its eDRX based on the extended, discontinuous reception period of the eDRX. The terminal device then determines the start time of the target paging time window corresponding to the eDRX type. At the start time of the target paging time window, the terminal device receives a paging message sent by the network device. This allows the terminal device to directly determine its target paging time window based on the type of its eDRX, improving the efficiency of determining the paging time window. Furthermore, since the start time of the paging time window corresponding to the eDRX type is obtained by the core network device based on the time information of the network device serving the terminal device, the paging time window corresponding to the eDRX type must be within the time range of the network device serving the terminal device, and the paging time windows of the network device and the terminal device are the same. This enables the network device to accurately paging the terminal device, improving the success rate of paging the terminal device.

[0200] Based on any of the above embodiments, the following, in conjunction with Figure 6 The process of the above paging method will be explained.

[0201] Figure 6 This is a schematic diagram illustrating a paging method provided in an embodiment of this application. Please refer to... Figure 6 This includes network devices, terminal devices, and core network devices. Specifically, the core network devices send eDRX threshold information and the start time of the paging time window corresponding to each eDRX type to the network devices. The network devices send eDRX threshold information and the start time, offset step size, and offset quantity of the paging time window corresponding to each eDRX type to the terminal devices. The network devices and terminal devices determine the type of the terminal device's eDRX as Type A based on the terminal device's eDRX and the eDRX threshold information.

[0202] Please see Figure 6The network device and the terminal device each determine the paging time window corresponding to type A. This paging time window includes paging time window A and paging time window B, with paging time window A starting at time A and paging time window B starting at time B. When the offset is 0 and no offset is needed for the terminal device's paging time window, the network device can send a paging message to the terminal device at either time A or time B. Since the start time of the paging time window corresponding to the eDRX type is obtained by the core network device based on the time information of the network device serving the terminal device, the paging time window corresponding to the eDRX type must be within the time range of the network device serving the terminal device. Furthermore, the paging time windows of the network device and the terminal device are the same, enabling the network device to accurately page the terminal device and improving the success rate of paging the terminal device.

[0203] Figure 7 This is a schematic diagram of a paging device provided in an embodiment of this application. Please refer to... Figure 7 The paging device 10 can be installed in a network device. The paging device 10 includes a first determining module 11 and a second determining module 12, wherein:

[0204] The first determining module 11 is used to determine the type of eDRX of the terminal device based on the period duration of the extended discontinuous reception eDRX of the terminal device;

[0205] The second determining module 12 is used to determine the start time information of the target paging time window of the terminal device corresponding to the type of the eDRX, and send a paging message to the terminal device according to the start time information of the target paging time window, wherein the start time information includes the time when the network device serves the terminal device.

[0206] In one possible implementation, the first determining module 11 is specifically used for:

[0207] The network device acquires threshold information for at least one eDRX used for eDRX classification.

[0208] The network device determines the type of eDRX of the terminal device based on the threshold information of the at least one eDRX and the period duration of the eDRX.

[0211] The network device obtains the start time information of at least one first paging time window corresponding to the type of eDRX of the terminal device;

[0212] The network device determines the start time information of the target paging time window of the terminal device based on the first information and the start time information of the first paging time window. The first information includes at least one of the following: offset quantity, offset step size, and the identifier of the terminal device. The offset quantity is the number of times the paging time window can be offset for terminals with the same start time of the first paging time window within the coverage service time range of the network device.

[0213] In one possible implementation, the network device obtains from the core network device the start time information of at least one first paging time window corresponding to the type of the terminal device's eDRX.

[0214] In one possible implementation, the start time information of the first paging time window includes at least one of the following:

[0215] The start time of network equipment service terminal equipment;

[0216] The time offset of the start time of the network device service terminal device.

[0217] In one possible implementation, the second determining module 12 is specifically used for:

[0219] In one possible implementation, the second determining module 12 is specifically used for:

[0220] The start time information of the target paging time window is determined based on the start time of the network device serving the terminal device, the time offset time, the identifier of the terminal device, the offset quantity, and the offset step size.

[0221] In one possible implementation, the offset number and the offset step size satisfy the following two conditions:

[0222] The offset amount is less than the ratio of the duration of the network device serving the terminal device to the preset time period;

[0223] The sum of the product of the offset quantity and the offset step size and the window length of the first paging time window is less than the duration for which the network device serves the terminal device.
