Abstract
Description
Technical Field
[0001] This application relates to the field of satellite communication technology, and in particular to a method, apparatus, electronic device and storage medium for dynamic terminal dwell. Background Technology
[0002] As the scale of low-Earth orbit satellite constellations continues to expand, their highly dynamic topology characteristics and the need for flexible networking are becoming increasingly prominent. Satellites need to frequently perform dynamic operations, such as maneuvering and obstacle avoidance operations to avoid other satellites, space debris, and other space targets.
[0003] However, these dynamic operations need to be achieved through the propulsion system or other attitude control system, which leads to additional power consumption, limiting the satellite's service resources, and causing communication link signal attenuation or even temporary interruption of communication services. At the same time, during dynamic operations, the satellite's orbit and attitude change rapidly. The information generated by the satellite when performing dynamic operations, namely satellite maneuvering information, may not be updated and transmitted to all terminals in a timely manner. This can easily cause terminals to select cells with limited service resources due to satellite maneuvering when performing cell selection or cell reselection, resulting in multiple cell reselections. Summary of the Invention

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown here.
[0113] The terms "first" and "second" in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone.

"A plurality" in this application can mean at least two, for example, two, three, or more; this application does not impose such limitations.
[0114] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description. It should be noted that in the embodiments of this application, certain existing industry solutions such as software, components, and models may be mentioned. These should be considered exemplary, intended only to illustrate the feasibility of implementing the technical solutions of this application, and do not imply that the applicant has already used or necessarily used such solutions.
[0115] The acquisition, transmission, storage, and use of data in this application all comply with the requirements of relevant national laws and regulations.
[0116] For ease of understanding, the technical terms used in this application are as follows:
[0117] Cell: In cellular mobile communication systems, a cell is the area covered by one of the base stations or a part of a base station (fan antenna), in which terminal devices can reliably communicate with the base station via a wireless channel; in satellite communication systems, a satellite cell is the area covered by the radio waves emitted by one of the satellites, in which radio communication stations can use the satellite as a relay for communication.
[0118] System Information Block (SIB): An SIB is a series of predefined data structures transmitted to user equipment via a broadcast channel. These SIBs contain key parameters for network operation, enabling terminals to correctly register, connect, and serve within the network. Different SIBs contain different types of information, depending on the network requirements and configuration.
[0119] The S-criteria are primarily used for cell evaluation during cell selection and initial access procedures. Their purpose is to determine whether a cell is suitable for a terminal to camp and provide service. The S-criteria include the Received Level Criterion (Srxlev) and the Received Quality Criterion (Squal), which evaluate the cell's signal strength and signal quality, respectively.
[0120] The R criterion is primarily used for cell priority assessment during the cell reselection process. It determines whether a cell needs to be reselected from the current cell to the target neighboring cell by calculating the priority scores (Rs and Rn) of the current cell and neighboring cells.
[0121] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application. Furthermore, the embodiments and features in the embodiments of this application can be combined with each other without conflict.
[0122] Please refer to Figure 1 This is a communication system architecture diagram of a terminal dynamic residency method provided in an embodiment of this application. It should be understood that the embodiments of this application are not limited to... Figure 1 In the system shown, in addition, Figure 1 The device in the diagram can be hardware, software defined by function, or a combination of both. For example... Figure 1 As shown in the embodiments of this application, the communication system architecture provided includes satellites and terminals.
[0123] The terminal can also be called a user terminal or user equipment (UE), mobile station (MS), mobile terminal (MT), etc. Terminals can be deployed on land, including indoor, outdoor, handheld, wearable, or vehicle-mounted devices. Examples include mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, vehicle-mounted terminals, and wireless terminals in self-driving vehicles.
[0124] It should be noted that the satellite mentioned in the embodiments of this application refers to network-side equipment mounted on a satellite, which may also be called a satellite base station.
[0125] It should be noted that, Figure 1 This application does not limit the number of satellites and terminals included in the communication system, but only as an example. Figure 1 The example shown is a communication system consisting of a satellite and a terminal.
[0126] After introducing the communication system of the embodiments of this application, the terminal dynamic residence method proposed in this application will be described below with specific embodiments.
[0127] Please refer to Figure 2 This is a flowchart of a terminal dynamic residency method provided in an embodiment of this application. The method is applied to... Figure 1 The method is performed in the terminal and includes the following steps.
[0128] In step 201, the satellite's maneuvering information is acquired, wherein the maneuvering information is used to characterize the information generated when the satellite performs dynamic operations.
[0129] In practical implementation, for pure satellite communication systems or satellite-enhanced systems, terminals can communicate directly with satellites. Since satellites periodically broadcast SIB information to all terminals within their coverage area, and in traditional terrestrial cellular networks, terminals mainly communicate with ground base stations (such as eNodeB in LTE or gNodeB in 5G NR), base stations also broadcast SIB information to terminals within their coverage area. Therefore, satellite mobility information can be added to the SIB information, so that the target terminal can obtain satellite mobility information based on the SIB information.
[0130] In practical implementation, in addition to obtaining satellite maneuvering information through broadcast SIB information, the terminal can also obtain satellite maneuvering information through dedicated signaling. Dedicated signaling is a point-to-point signaling link established between the terminal and the satellite or terrestrial network. The terminal requests and receives maneuvering information through RRC (Radio Resource Control) signaling or proprietary protocols. The above two methods of obtaining maneuvering information can be used individually or in combination. The methods of obtaining satellite maneuvering information described in this application are only for illustration and explanation of this application and are not intended to limit this application. The specific method of obtaining satellite maneuvering information may be designed according to actual needs, and this application does not limit it.
[0131] In practice, maneuvering information is used to characterize information generated when a satellite performs dynamic operations, such as obstacle avoidance maneuvers, orbital adjustments, and attitude changes. Satellite maneuvering information includes at least one of the following:
[0132] Satellite maneuver categories, where different satellite maneuver categories characterize different degrees of satellite service limitation;
[0133] The cell selection offset value corresponding to the satellite maneuver includes the first signal strength offset value and the first signal quality offset value used to adjust the S criterion;
[0134] Satellite maneuver timing information, including the start time and duration of the satellite maneuver;
[0135] Satellite maneuver power usage information;
[0136] The cell reselection offset value corresponding to the satellite maneuver includes the second signal quality offset value used to adjust the R criterion, the third signal quality offset value used to adjust the S criterion, and the third signal strength offset value.
[0137] The different satellite maneuver categories include: a first satellite maneuver category indicating that the degree of satellite service restriction is lower than a first preset level; a second satellite maneuver category indicating that the degree of satellite service restriction is not lower than the first preset level and is lower than a second preset level; and a third satellite maneuver category indicating that the degree of satellite service restriction is not lower than the second preset level.
[0138] For example, in the first satellite maneuver category, the satellite's service capability is minimally affected, and normal communication service quality can generally be maintained. In the second satellite maneuver category, the satellite's service capability is somewhat limited, but it can still provide a certain level of service, although some performance indicators (such as bandwidth and latency) may need to be reduced. In the third satellite maneuver category, the satellite's service capability is significantly limited, and it may only be able to provide very limited service, or even be temporarily unable to provide service. It should be noted that in practical applications, more satellite maneuver categories can be defined according to needs, and it is not limited to the three categories in this application.
[0139] In step 202, a dwell time assessment of the satellite cell is performed based on the maneuver information.
[0140] In practice, the target terminal's status information can be used to determine whether to conduct a cell selection stay assessment or a cell reselection stay assessment.
[0141] In practice, during the cell selection phase, the target terminal mainly evaluates whether the satellites it finds are suitable for connection; while during the cell reselection phase, more attention is paid to neighboring satellites as potential new service nodes.
[0142] In practice, the target terminal's status information may include the target terminal's location information, service requirements, network status, etc. If, based on the target terminal's status information, it is determined that the target terminal is attempting to access the network for the first time or is moving from a non-signal area to a signal-covered area, then a cell selection and stationing assessment is performed, and the satellites searched by the terminal are identified as the satellites to be assessed. If the target terminal already has a stationing satellite, then a cell reselection and stationing assessment is performed, and neighboring satellites are identified as the satellites to be assessed.
[0143] In practice, when the satellite being evaluated is a satellite searched by the terminal, cell selection and retention evaluation is performed on the cell of the searched satellite based on the maneuvering information of the satellite searched by the terminal; when the satellite being evaluated is a neighboring satellite, cell reselection and retention evaluation is performed on the cell of the neighboring satellite based on the maneuvering information of the currently stationed satellite and the maneuvering information of the neighboring satellite.
[0144] The following sections will introduce the terminal dynamic residency method of this application from two aspects: community selection residency assessment and community reselection residency assessment.
[0145] Firstly, the community selection and residency assessment.
[0146] When the satellite maneuver information includes the cell selection offset value corresponding to the satellite maneuver, including the first signal strength offset value and the first signal quality offset value used to adjust the S criterion, please refer to... Figure 3 This is a flowchart of a method for dynamic terminal camping during cell selection provided in an embodiment of this application, and the method includes the following steps.
[0147] In step 301, the first receiving level criterion in the S criterion is modified based on the first signal strength offset value to obtain the modified first receiving level criterion.
[0148] In practical implementation, the formula for the first received level criterion in the S-criteria is as follows:
[0149] Srxlev=Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation-Qoffsettemp;
[0150] Wherein, Qrxlevmeas is the measured value of the cell reference signal received power of the searched satellite measured by the terminal, Qrxlevmin is the minimum received level threshold set by the network, Qrxlevminoffset is the temporary offset, Pcompensation is the compensation value, and Qoffsettemp is another temporary offset.
[0151] In practice, the first signal strength offset value can be defined as Qoffset. maneuver1PThe modification can be based on the existing first received level criterion and Qoffset. maneuver1P The difference is used to obtain the modified first received level criterion, Srxlev-Qoffset. maneuver1P .
[0152] In step 302, the first reception quality criterion in the S criterion is modified based on the first signal quality offset value to obtain the modified first reception quality criterion.
[0153] In practical implementation, the formula for the first acceptance quality criterion in the S criterion is as follows:
[0154] Squal=Qqualmeas-(Qqualmin+Qqualminoffset)-Qoffsettemp;
[0155] Where Qqualmeas is the cell signal quality measurement value of the searched satellite measured by the terminal, Qqualmin is the minimum reception quality threshold set by the network, Qqualminoffset is the temporary offset, and Qoffsettemp is another temporary offset.
[0156] In practice, the first signal quality offset value can be defined as Qoffset. maneuver1Q The modification can be based on the existing first receiving quality criterion and Qoffset. maneuver1Q The difference is calculated to obtain the modified first reception quality criterion, Squal-Qoffset. maneuver1Q .
[0157] In step 303, the modified first S criterion is determined based on the modified first receive level criterion and the modified first receive quality criterion.
[0158] In practical implementation, the modified first received level criterion is Srxlev-Qoffset. maneuver1P The revised first reception quality criterion is Squal-Qoffset. maneuver1Q
[0159] Therefore, the modified first S criterion is: Srxlev - Qoffset maneuver1P and Squal-Qoffset maneuver1Q .
[0160] In step 304, a dwell assessment is performed on the cell of the searched satellite based on the reference signal received power measurement value of the cell of the searched satellite, the signal quality measurement value of the cell of the searched satellite, and the modified first S criterion.
[0161] In practice, the measured reference signal received power of the cell of the searched satellite and the modified first received level criterion Srxlev-Qoffset are used. maneuver1P The system determines the signal strength assessment value of the cells of the searched satellites to perform a dwell assessment of the signal strength of the cells of the searched satellites, and, based on the signal quality measurements of the cells of the searched satellites and the modified first reception quality criterion Squal-Qoffset... maneuver1Q The signal quality assessment value of the cell for the searched satellite is determined in order to conduct a dwell assessment of the signal quality of the cell for the searched satellite.
[0162] In practical implementation, when the satellite maneuver information also includes satellite maneuver categories, taking the example of satellite maneuver categories including the first satellite maneuver category, the second satellite maneuver category, and the third satellite maneuver category, please refer to [reference needed]. Figure 4 This is a flowchart of another method for dynamic terminal camping during cell selection provided in this application embodiment, and the method includes the following steps.
[0163] In step 401, the satellite maneuver category is determined based on the satellite maneuver information.
[0164] In step 402, it is determined whether the satellite maneuver category is the first maneuver category. If so, proceed to step 403; otherwise, proceed to step 404.
[0165] In step 403, an evaluation strategy corresponding to the first maneuver category is selected to perform cell selection and dwell evaluation on the cells of the searched satellites.
[0166] In practice, if the satellite maneuver category is the first satellite maneuver category, the satellite's service capability is less affected and can basically maintain normal communication service quality. In this case, the evaluation strategy is to use the unmodified S criterion to perform cell selection and retention evaluation on the cells of the searched satellites.
[0167] In step 404, it is determined whether the satellite maneuver category is the second satellite maneuver category. If so, proceed to step 405; otherwise, proceed to step 406.
[0168] In step 405, an evaluation strategy corresponding to the second maneuver category is selected to perform cell selection and dwell evaluation on the cells of the searched satellites.
[0169] In practice, if the satellite maneuver category is the second satellite maneuver category, the satellite's service capability is somewhat limited under this condition, but it can still provide a certain level of service. However, it may be necessary to reduce certain performance indicators (such as bandwidth, latency, etc.). In this case, the evaluation strategy is to use the modified first S criterion to perform cell selection and residency evaluation on the cells of the searched satellites.
[0170] In practice, the specific implementation process of using the modified first S criterion to perform cell selection and retention assessment on the cells of the searched satellites can be referred to steps 301 to 304, which will not be repeated here.
[0171] In step 406, an evaluation strategy corresponding to the third maneuver category is selected to perform cell selection and dwell evaluation on the cells of the searched satellites.
[0172] In specific implementation, if the satellite maneuver category is the third satellite maneuver category, the satellite's service capability is significantly limited in this state, and it may only be able to provide very limited services, or even be temporarily unable to provide services. In this case, the evaluation strategy is to not perform cell selection and dwell evaluation on the cells of the searched satellite, or to perform cell selection and dwell evaluation on the cells of the searched satellite after a preset interval period is met.
[0173] In specific implementation, when the satellite maneuver information also includes satellite maneuver time information, a satellite maneuver time window can be determined based on the satellite maneuver start time and satellite maneuver duration. Within the satellite maneuver time window, based on the reference signal received power measurement value of the cell of the searched satellite, the signal quality measurement value of the cell of the searched satellite, and the modified first S criterion, a cell selection and retention assessment is performed on the cell of the searched satellite. That is, within the satellite maneuver time window, steps 301 to 304 and step 404 are executed.
[0174] Secondly, the community re-selection and residency assessment.
[0175] In practice, before conducting cell reselection and retention assessments for adjacent satellite cells, it is necessary to determine the appropriate cell reselection method based on the cell category. Please refer to [reference needed]. Figure 5 This is a flowchart of a method for determining the cell category during cell reselection provided in an embodiment of this application, and the method includes the following steps.
[0176] In step 501, the frequency band category of the neighboring satellite's cell is determined based on the frequency information of the cell of the currently stationed satellite and the frequency information of the cells of the neighboring satellite.
[0177] In practice, frequency information can be extracted from the SIB information of the currently stationed satellite and neighboring satellites. If the frequency of the neighboring satellite is the same as that of the currently stationed satellite, it is classified as the same frequency band. If the frequency of the neighboring satellite is different from that of the currently stationed satellite, it is classified as the different frequency band.
[0178] In step 502, the priority category of the cells of the neighboring satellites is determined based on the priority information of the cells of the currently stationed satellite and the priority information of the cells of the neighboring satellites.
[0179] In practice, priority information can be extracted from the SIB information of the currently stationed satellite and neighboring satellites. If the priority of a neighboring satellite is higher than that of the currently stationed satellite, it is classified as high priority. If the priority of a neighboring satellite is equal to that of the currently stationed satellite, it is classified as equal priority. If the priority of a neighboring satellite is lower than that of the currently stationed satellite, it is classified as low priority.
[0180] In step 503, the cell category of adjacent satellite cells is determined based on frequency band category and priority category. The cell category mainly includes cells in the same frequency band or with the same priority but different frequency bands, cells in different frequency bands or different systems and the cells are high priority cells, and cells in different frequencies and different systems and the cells are low priority cells.
[0181] Among them, cells in the same frequency band or different frequency bands with the same priority can be cells in the same frequency band or cells in different frequency bands but with the same priority. These cells are usually easier to switch over because they are either in the same frequency band or have the same priority.
[0182] Cells in different frequency bands or systems and which are high-priority cells: These cells are not only in different frequency bands or systems, but also have higher priority. Although the handover cost of such cells is higher, they may provide better service quality due to their high priority.
[0183] Inter-frequency and inter-system cells that are low-priority cells: These cells are located in different frequency bands or systems and have lower priority. For example, when the service quality of the currently stationed satellite is significantly reduced and there are no other available high-priority cells, it is possible to choose to station in such cells.
[0184] For example, the target terminal is communicating through its current satellite. There are three neighboring satellites around the current satellite: neighboring satellite A, neighboring satellite B, and neighboring satellite C.
[0185] If the frequency information of the neighboring satellite A is the same as that of the currently stationed satellite, and the priority information is the same as that of the currently stationed satellite, then the frequency band category of the neighboring satellite A is the same frequency band, the priority category is the same priority, and the cell category of the neighboring satellite A is a cell in the same frequency band or a cell in the same priority but different frequency band.
[0186] If the frequency information of neighboring satellite B is different from that of the currently stationed satellite, and its priority information is higher than that of the currently stationed satellite, then the frequency band category of neighboring satellite B is different frequency band, the priority category is high priority, and the cell category of neighboring satellite B is a cell of different frequency band or different system and that cell is a high priority cell.
[0187] If the frequency information of neighboring satellite C is different from that of the currently stationed satellite, and its priority information is lower than that of the currently stationed satellite, then the frequency band category of neighboring satellite C is different frequency band, the priority category is low priority, and the cell category of neighboring satellite C is different frequency and different system cell, and this cell is a low priority cell.
[0188] The following describes the terminal dynamic camping method during cell reselection when the cell categories are cells in the same frequency band or cells in the same priority but different frequency bands, cells in different frequency bands or different systems and the cell is a high-priority cell, and cells in different frequencies and different systems and the cell is a low-priority cell.
[0189] Scenario 1: Cells that are in the same frequency band or have the same priority but different frequency bands.
[0190] When the satellite maneuver information includes the cell reselection offset value corresponding to the satellite maneuver, and the second signal quality offset value used to adjust the R criterion, please refer to... Figure 6 This is a flowchart of a method for dynamic terminal camping during cell reselection provided in an embodiment of this application, and the method includes the following steps.
[0191] In step 601, the first priority criterion corresponding to the cell of the currently stationed satellite in the R criterion is modified based on the second signal quality offset value to obtain the modified first priority criterion.
[0192] In practical implementation, the formula for the first priority criterion corresponding to the cell where the currently residing satellite is located in the R criterion is as follows:
[0193] R s =Q meas,s +Q hyst -Qoffset temp ;
[0194] Among them, Q meas,s Q is the reference signal received power measurement of the cell where the terminal currently hosts the satellite. hyst The lag value is Qoffset. temp This is a temporary offset value.
[0195] In practice, the second signal quality offset value can be defined as Qoffset. maneuver2 The modification can be based on the existing first priority criterion and Qoffset. maneuver2 The difference is taken to obtain the modified first priority criterion, R. s -Qoffset maneuver2 .
[0196] In step 602, the second priority criterion corresponding to the cell of the neighboring satellite in the R criterion is modified based on the second signal quality offset value to obtain the modified second priority criterion.
[0197] In practical implementation, the formula for the second priority criterion corresponding to the cell of adjacent satellites in the R criterion is as follows:
[0198] R n =Q meas,n -Qoffset-Qoffset temp ;
[0199] Among them, Q meas,n The reference signal received power measurement value of the neighboring satellite cell is given by the terminal, and Qoffset is the offset. temp This is a temporary offset value.
[0200] In practice, the modification can be based on the existing second priority criterion and Qoffset. maneuver2 By taking the difference, we obtain the modified second priority criterion as R. n -Qoffset maneuver2 .
[0201] In step 603, the modified R criterion is determined based on the modified first priority criterion and the modified second priority criterion.
[0202] In practice, the revised first priority criterion is R. s -Qoffset maneuver2 The revised second priority criterion is R. n -Qoffset maneuver2 .
[0203] Therefore, the revised R criterion is R s -Qoffset maneuver2 and R n -Qoffset maneuver2 .
[0204] In step 604, based on the reference signal received power measurement of the cell of the currently stationed satellite, the reference signal received power measurement of the cell of the neighboring satellite, and the modified R criterion, a stationing assessment of the cell of the neighboring satellite is performed.
[0205] In practice, the reference signal received power measurement of the cell currently hosting the satellite and the modified first priority criterion R are used. s -Qoffset maneuver2 Calculate the cell priority score of the currently residing satellite; and, based on the reference signal received power measurement of the cell from neighboring satellites and the modified second priority criterion R. n -Qoffset maneuver2The priority score of the cell of the neighboring satellite is calculated. Then, based on the cell priority score of the currently stationed satellite and the cell priority score of the neighboring satellite, the cell of the neighboring satellite is evaluated for stationing.
[0206] In specific implementation, when the satellite maneuver information also includes satellite maneuver time information, a satellite maneuver time window can be determined based on the satellite maneuver start time and satellite maneuver duration. Within the satellite maneuver time window, based on the reference signal received power measurement value of the cell of the currently stationed satellite, the reference signal received power measurement value of the cell of the neighboring satellite, and the modified R criterion, a stationing assessment of the cell of the neighboring satellite is performed. That is, within the satellite maneuver time window, steps 601 to 604 above are executed.
[0207] Scenario 2: The cell category is a cell with different frequency bands or different systems and the cell is a high-priority cell.
[0208] When the satellite maneuver information includes the cell reselection offset value corresponding to the satellite maneuver, including the third signal quality offset value and the third signal strength offset value used to adjust the S criterion, please refer to... Figure 7 This is a flowchart of another method for dynamic terminal camping during cell reselection provided in this application embodiment, and the method includes the following steps.
[0209] In step 701, the second reception quality criterion in the S criterion is modified based on the third signal quality offset value, and the modified second reception quality criterion is determined.
[0210] In practical implementation, the second reception quality criterion in the S criterion is Squal, and the third signal quality offset value can be defined as Qoffset. maneuver3Q The modification can be based on the existing second receiving quality criterion and Qoffset. maneuver3Q The difference is calculated to obtain the modified second reception quality criterion, Squal-Qoffset. maneuver3Q .
[0211] In step 702, the second receiving level criterion in the S criterion is modified based on the third signal strength offset value, and the modified second receiving level criterion is determined.
[0212] In practical implementation, the second receiving level criterion in the S criterion is Srxlev, and the third signal strength offset value can be defined as Qoffset. maneuver3P The modification can be based on the existing second receive level criterion and Qoffset. maneuver3P The difference is used to obtain the modified second receive level criterion, Srxlev-Qoffset. maneuver3P .
[0213] In step 703, the modified second S criterion is determined based on the modified second reception quality criterion and the modified second reception level criterion.
[0214] In practical implementation, the modified second receiving level criterion is Srxlev-Qoffset. maneuver3P The revised second reception quality criterion is Squal-Qoffset. maneuver3Q .
[0215] Therefore, the modified second S criterion is: Srxlev - Qoffset maneuver3P and Squal-Qoffset maneuver3Q .
[0216] In step 704, within a preset time interval, a dwell assessment of the neighboring satellite's cell is performed based on the reference signal received power measurement value of the neighboring satellite's cell, the signal quality measurement value of the neighboring satellite's cell, and the modified second S criterion.
[0217] In practice, the preset time interval can be TreselectionRAT, based on the reference signal received power measurement of neighboring satellite cells and the modified second received level criterion Srxlev-Qoffset. maneuver3P The system determines the signal strength assessment values of neighboring satellite cells to perform a dwell assessment of the signal strength of neighboring satellite cells, and, based on the signal quality measurements of neighboring satellite cells and the modified second reception quality criterion Squal-Qoffset... maneuver3Q The signal quality assessment value of the cells of neighboring satellites is determined in order to conduct a dwell assessment of the signal quality of the cells of neighboring satellites.
[0218] In practice, before conducting a dwell time assessment of adjacent satellite cells, it can be determined that the received signal quality threshold of the currently dwelling satellite cell is preset and that the terminal dwell time in the currently dwelling satellite cell exceeds the preset duration.
[0219] For example, when a terminal stays in the cell of the currently stationed satellite for more than 1 second and receives the cell signal quality threshold of the currently stationed satellite, where the cell signal quality threshold of the currently stationed satellite is ThreshServingLowQ.
[0220] In specific implementation, when the satellite maneuver information also includes satellite maneuver time information, a satellite maneuver time window can be determined based on the satellite maneuver start time and satellite maneuver duration. Within the satellite maneuver time window, based on the maneuver information of the currently stationed satellite and the maneuver information of the neighboring satellites, as well as the modified second S criterion, a cell reselection and stationing assessment is performed on the cells of the neighboring satellites. That is, within the satellite maneuver time window, the above steps 701 to 704 are executed.
[0221] Scenario 3: The cell category is a different frequency and different system cell and the cell is a low priority cell.
[0222] When the satellite maneuver information includes the cell reselection offset value corresponding to the satellite maneuver, including the third signal quality offset value and the third signal strength offset value used to adjust the S criterion, please refer to... Figure 8 This is a flowchart of another method for dynamic terminal camping during cell reselection provided in this application embodiment, and the method includes the following steps.
[0223] In step 801, the second reception quality criterion in the S criterion is modified based on the third signal quality offset value in the cell reselection offset value, and the modified second reception quality criterion is determined.
[0224] The specific implementation process of step 801 is the same as that of step 701, and will not be repeated here.
[0225] In step 802, the second receiving level criterion in the S criterion is modified based on the third signal strength offset value in the cell reselection offset value, and the modified second receiving level criterion is determined.
[0226] The specific implementation process of step 802 is the same as that of step 702, and will not be repeated here.
[0227] In step 803, the modified second S criterion is determined based on the modified second reception quality criterion and the modified second reception level criterion.
[0228] The specific implementation process of step 803 is the same as that of step 703, and will not be repeated here.
[0229] In step 804, within a preset time interval, a dwell assessment is performed on the cells of neighboring satellites based on the signal quality measurement value of the cell of the currently dwelling satellite, the reference signal received power measurement value of the cell of the currently dwelling satellite and the unmodified S criterion, as well as the reference signal received power measurement value of the cell of the neighboring satellite, the signal quality measurement value of the cell of the neighboring satellite and the modified second S criterion.
[0230] In practice, the preset time interval can be TreselectionRAT. Based on the reference signal received power measurement of the cell currently residing with the satellite and the unmodified S criterion, the signal strength assessment value of the cell currently residing with the satellite is determined. Based on the reference signal received power measurement of the cells of neighboring satellites and the modified second receive level criterion Srxlev-Qoffset, the signal strength assessment value of the cell currently residing with the satellite is determined. maneuver3P This involves determining the signal strength assessment values of cells belonging to neighboring satellites, and performing a dwell assessment of cells belonging to neighboring satellites based on the signal strength assessment values of the currently occupied satellite cells and the cells belonging to neighboring satellites; and...
[0231] Based on the signal quality measurements of the cell currently residing with the satellite and the unmodified S criterion, determine the signal quality assessment value of the cell currently residing with the satellite. Based on the signal quality measurements of cells of neighboring satellites and the modified second reception quality criterion Squal-Qoffset, determine the signal quality assessment value of the cell currently residing with the satellite. maneuver3Q The signal quality assessment value of the cell of the neighboring satellite is determined, and based on the signal quality assessment value of the cell of the currently stationed satellite and the signal quality assessment value of the cell of the neighboring satellite, a stationing assessment of the cell of the neighboring satellite is performed.
[0232] In practice, before conducting a dwell time assessment of adjacent satellite cells, it can be determined that the received signal quality threshold of the currently dwelling satellite cell is preset and that the terminal dwell time in the currently dwelling satellite cell exceeds the preset duration.
[0233] For example, when a terminal stays in the cell of the currently stationed satellite for more than 1 second and receives the cell signal quality threshold of the currently stationed satellite, where the cell signal quality threshold of the currently stationed satellite is ThreshServingLowQ.
[0234] In specific implementation, when the satellite maneuver information also includes satellite maneuver time information, a satellite maneuver time window can be determined based on the satellite maneuver start time and satellite maneuver duration. Within the satellite maneuver time window, based on the signal quality measurement value of the cell of the currently stationed satellite, the reference signal received power measurement value of the cell of the currently stationed satellite and the unmodified S criterion, as well as the reference signal received power measurement value of the cell of the neighboring satellite, the signal quality measurement value of the cell of the neighboring satellite and the modified second S criterion, a stationing assessment of the cells of the neighboring satellite is performed. That is, within the satellite maneuver time window, steps 801 to 804 above are executed.
[0235] In specific implementation, if any of the above steps 601-604, 701-704, and 801-804 include satellite maneuvering categories in the satellite maneuvering information (taking the satellite maneuvering categories as including a first satellite maneuvering category, a second satellite maneuvering category, and a third satellite maneuvering category as an example), please refer to... Figure 9 This is a flowchart of another method for dynamic terminal camping during cell reselection provided in this application embodiment, and the method includes the following steps.
[0236] In step 901, the satellite maneuver category is determined based on the satellite maneuver information.
[0237] In step 902, it is determined whether the satellite maneuver category is the first maneuver category. If so, proceed to step 903; otherwise, proceed to step 904.
[0238] In step 903, an evaluation strategy corresponding to the first maneuver category is selected to perform cell reselection and residency evaluation on the cells of adjacent satellites.
[0239] In practice, if the satellite maneuver category is the first satellite maneuver category, the satellite's service capability is less affected and can basically maintain normal communication service quality. In this case, the evaluation strategy is to use the unmodified R criterion or the unmodified S criterion to evaluate the cell reselection and retention of adjacent satellite cells.
[0240] In step 904, it is determined whether the satellite maneuver category is the second satellite maneuver category. If so, proceed to step 905; otherwise, proceed to step 906.
[0241] In step 905, an evaluation strategy corresponding to the second maneuver category is selected to perform cell reselection and residency evaluation on the cells of adjacent satellites.
[0242] In practice, if the satellite maneuver category is the second satellite maneuver category, the satellite's service capability is somewhat limited under this condition, but it can still provide a certain level of service. However, it may be necessary to reduce certain performance indicators (such as bandwidth, latency, etc.). In this case, the evaluation strategy is determined to be the modified R criterion or the modified second S criterion, and cell reselection and retention evaluation is performed on the cells of adjacent satellites.
[0243] In practice, if the satellite maneuver category is the second satellite maneuver category, the evaluation strategy can also be to adjust the priority of the adjacent satellite cell to a preset priority or to add the adjacent satellite cell to the reselection candidate list after a preset time. For example, the adjacent satellite cell can be set to the lowest priority, or the longest predefined time for not being included in the reselection list can be set, such as 300 seconds.
[0244] In step 906, an evaluation strategy corresponding to the third maneuver category is selected to perform cell reselection and residency evaluation on the cells of neighboring satellites.
[0245] In practice, if the satellite maneuver category is the third satellite maneuver category, the satellite's service capability is significantly limited under this condition. It may only be able to provide very limited services or even be temporarily unable to provide services. In this case, the assessment strategy is to not conduct cell reselection and residency assessments on the cells of adjacent satellites, or to conduct cell reselection and residency assessments on the cells of adjacent satellites after a preset interval period is met.
[0246] In practice, if the satellite maneuver information also includes satellite maneuver power occupancy information, then based on the satellite maneuver power occupancy information and the preset satellite maneuver power occupancy threshold, when it is determined that the satellite maneuver power occupancy information is greater than the preset satellite maneuver power occupancy threshold, a cell reselection and retention assessment of the adjacent satellite cells can be triggered.
[0247] In step 203, when the preset dwell conditions are met based on the evaluation results, the satellite's cell is determined as the dwell cell.
[0248] In specific implementation, when the satellite being evaluated is a found satellite, since the cell selection and dwell assessment of the cell of the found satellite is based on the measured reference signal received power value of the cell of the found satellite, the measured signal quality value of the cell of the found satellite, and the modified first S criterion, it can be set that if the signal strength assessment value of the cell of the found satellite meets the preset first signal strength value and the signal quality assessment value of the cell of the found satellite meets the preset first signal quality value, then it is determined that the cell of the found satellite meets the preset dwell conditions, wherein the preset first signal strength value and the preset first signal quality value are set to 0.
[0249] In practice, when the satellite being evaluated is an adjacent satellite, the cell category of the adjacent satellite's cell can be determined. If the adjacent satellite's cell is a cell in the same frequency band or a cell in the same priority but different frequency band, the preset dwelling conditions of the adjacent satellite's cell can be set if the priority score of the adjacent satellite's cell is greater than the priority score of the currently dwelling satellite's cell.
[0250] In specific implementation, if the cell is a cell in a different frequency band or system and is a high-priority cell, it can be set that if the signal strength assessment value of the cell of the adjacent satellite meets the preset second signal strength value, or the signal quality assessment value of the cell of the adjacent satellite meets the preset second signal quality value, then the cell of the adjacent satellite meets the preset dwell conditions.
[0251] In practical implementation, if the cell is a low-priority cell and operates in a different frequency band or system, a setting can be made that if the signal quality assessment value of the cell currently residing in the satellite is less than a preset signal quality threshold for the cell currently residing in the satellite, and the signal quality assessment value of the cell of the adjacent satellite is greater than a preset third signal quality value; or
[0252] If the signal strength assessment value of the cell of the currently stationed satellite is less than the preset signal strength threshold of the cell of the currently stationed satellite, and the signal strength assessment value of the cell of the neighboring satellite is greater than the preset third signal strength value, then it is determined that the cell of the neighboring satellite meets the preset stationing conditions.
[0253] In this embodiment, the terminal obtains satellite mobility information and adds satellite mobility information parameters during cell selection and cell reselection. This allows the terminal to consider satellite mobility during cell selection and cell reselection, effectively avoiding the selection or reselection of cells with limited service power resources due to satellite mobility, thus avoiding multiple reselections. This maximizes the terminal's ability to camp on a suitable cell, improves the efficiency of cell camping, and enhances the user experience.
[0254] Based on the same technical concept, this application also provides a terminal dynamic dwell device. The principle of the terminal dynamic dwell device in solving the problem is similar to that of the above-mentioned terminal dynamic dwell method. Therefore, the implementation of the terminal dynamic dwell device can refer to the implementation of the terminal dynamic dwell method, and the repeated parts will not be described again.
[0255] Figure 10 The present application provides a schematic diagram of the structure of a terminal dynamic dwell device, including an acquisition module 1001, an evaluation module 1002, and a dwell module 1003.
[0256] The acquisition module 1001 is used to acquire the satellite's maneuvering information, which is used to characterize the information generated when the satellite performs dynamic operations;
[0257] Evaluation module 1002 is used to perform a dwell time assessment of the satellite's cell based on the maneuvering information;
[0258] The dwell module 1003 is used to determine the cell of the satellite as the dwell cell when the preset dwell conditions are met based on the evaluation results.
[0259] In some embodiments, the mobility information includes at least one of the following:

[0266] Based on the satellite mobility information searched by the terminal, a cell selection and dwell assessment is performed on the cells of the searched satellites;
[0267] Based on the maneuver information of the currently stationed satellite and the maneuver information of neighboring satellites, a cell reselection and stationing assessment is performed on the cells of the neighboring satellites.
[0268] In some embodiments, the evaluation module 1002 is specifically used for:
[0269] Based on the first signal strength offset value, the first receiving level criterion in the S criterion is modified to obtain the modified first receiving level criterion;
[0270] Based on the first signal quality offset value, the first reception quality criterion in the S criterion is modified to obtain the modified first reception quality criterion;
[0271] Based on the modified first receiving level criterion and the modified first receiving quality criterion, the modified first S criterion is determined;
[0272] Based on the measured reference signal received power of the cell of the searched satellite, the measured signal quality of the cell of the searched satellite, and the modified first S criterion, a dwell assessment is performed on the cell of the searched satellite.
[0273] In some embodiments, the evaluation module 1002 is further configured to:
