Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0090] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0091] Figure 1 A schematic diagram of interaction between a mobile terminal and a mobile base station provided in this embodiment is as follows.

[0092] S110. The mobile base station determines a data transmission period.

[0093] Among them, the mobile base station refers to a radio transceiver station that transmits information to and from a mobile terminal through a mobile communication exchange center in a certain radio coverage area. The mobile base station may be a backpack base station, the radio coverage area may be a satellite signal coverage area, the mobile communication exchange center may be a satellite base station, and the mobile terminal may be a smart device used by the user (such as a smart phone, a personal computer, etc.).

[0094] The data transmission period is a period of time during which the mobile base station instructs the mobile terminal to perform data transmission. The mobile terminal may send uplink data to be transmitted to the mobile base station within the period of time.

[0095] Optionally, determining the data transmission period may include:

[0096] Obtaining a satellite reference period corresponding to the location information of the mobile base station; determining a preset offset period before the satellite reference period; and determining a data transmission period based on the satellite reference period and the preset offset period.

[0097] Among them, the satellite reference period can be used to describe the time period when the mobile base station is covered by the signals of one or more satellites. The satellite reference period of the mobile base station can be determined by the core network equipment according to the location information of the mobile base station, or determined by the mobile base station.

[0098] The satellite reference period corresponds to the position information of the mobile base station. When the satellite reference period is a continuous period corresponding to at least two satellites and overlapping, the overlapping continuous period can be deduplicated to simplify the satellite reference period.

[0099] like Figure 2A As shown, the satellite reference periods are: T1-T2 period, T3-T4' period, T1'-T2' period and after T4 time, the overlapping periods in the satellite reference period are deduplicated, see Figure 2B As shown in the example, the new satellite reference time period is obtained as follows: the time period T1-T2' and after the time T3, wherein at least one non-overlapping continuous time period includes: the time period T1-T2' and after the time T3.

[0100] The preset offset period before the satellite reference period can be a preset time length, with the satellite reference period as Figure 2B The T1-T2 period in the example is as follows: Figure 2C As shown, the satellite reference period is such as the period corresponding to T1-T2, the preset offset period is the period corresponding to T0-T1, and the period corresponding to T1-T2 is extended to the period corresponding to T0-T2, then the obtained data transmission period can be the period corresponding to T0-T2.

[0101] Therefore, the starting time point of the data transmission period is earlier than the starting time point of the satellite reference period, so that the mobile terminal can first transmit the target uplink data to the mobile base station, and the mobile base station transmits the uplink data to the core network device through the satellite link during the satellite signal coverage period. Among them, the satellite signal coverage period is later, which can avoid the problem that after the uplink data of the mobile terminal is transmitted to the mobile base station, the mobile base station has no satellite link and cannot transmit the uplink data to the core network device in time, resulting in an increase in data transmission delay.

[0102] It should be noted that the time length of the data transmission period may be the same as or different from the time length of the satellite reference period, and the present disclosure does not limit this.

[0103] In some embodiments, optionally, the mobile base station acquires the satellite reference period corresponding to the location information of the mobile base station, which may include:

[0104] The mobile base station sends the location information of the mobile base station to the core network device; the core network device receives the satellite reference time period corresponding to the location information, the satellite reference time period is determined by the core network device based on the satellite reference information, and the satellite reference information is determined by the core network device based on the location information.

[0105] Data communication between mobile base stations and core network equipment can be found in Figure 2D As shown in the example, the mobile base station is connected to the satellite through wireless signals, and then connected to the network elements of the core network equipment on the ground through the satellite. For the communication between the ordinary base station and the core network equipment, it is equivalent to replacing the "base station-core network equipment" transmission section of the traditional wireless cellular network with a satellite link.

[0106] The location information of the mobile base station may be the longitude and latitude of the mobile base station on a global map. The longitude and latitude of the mobile base station can effectively locate the unique location coordinates of the mobile base station in the earth coordinate system.

[0107] The satellite reference information may include satellite ephemeris information, and the satellite ephemeris information may be the ephemeris information of the target satellite.

[0108] The core network equipment can obtain the ephemeris information of the target satellite from the network management platform, wherein the ephemeris information of the target satellite may be the ephemeris information of all satellites in the satellite network operated by the operator, or the ephemeris information of some satellites used to serve the mobile base station.

[0109] like Figure 2A As shown in the example, the operator operates two satellites, and the time corresponding to their ephemeris information is represented by straight lines and dotted lines respectively. The straight double-arrow line segment represents the operating information of satellite A. Satellite A works during the T1-T2 period and the T3-T4' period; the dotted double-arrow line segment represents the operating information of satellite B. Satellite B works during the T1'-T2' period and after T4.

[0110] Among them, if the ephemeris information obtained by the core network device contains the information of the complete cycle of satellite A and satellite B, the ephemeris information of any satellite at any time can be inferred. If the ephemeris information obtained by the core network device does not contain the information of the complete cycle of satellite A and satellite B, the ephemeris information of any satellite at any time cannot be inferred, and only the satellite ephemeris information in the future can be inferred.

[0111] The ephemeris information of the target satellite is the ephemeris information of all satellites that provide satellite signal coverage to the mobile base station in a future period of time, wherein the ephemeris information can reflect the position and speed of the corresponding satellite.

[0112] For example, the ephemeris information of the target satellite may correspond to the ephemeris information of each satellite corresponding to the position information of the covering mobile base station in the T5-T6 time period, wherein the T5 time and the T6 time may be absolute time, such as the time starting from 0:0:00 on January 1, 1980, or the ephemeris information of the target satellite may correspond to the satellite ephemeris information within the future T7 time period starting from now, wherein T7 may represent a period of time, such as 6 hours.

[0113] In some other embodiments, optionally, the mobile base station acquires the satellite reference period corresponding to the position information of the mobile base station, including:

[0114] The mobile base station obtains satellite reference information of the mobile base station; based on the satellite reference information and the position information of the mobile base station, determines the satellite reference time period corresponding to the position information.

[0115] The mobile base station may obtain the satellite reference information of the mobile base station by communicating with the core network device and receiving the satellite reference information of the mobile base station sent by the core network device, so as to determine the satellite reference time period corresponding to the location information.

[0116] The satellite reference information may include satellite ephemeris information, which may be the ephemeris information of the target satellite. The ephemeris information of the target satellite is the ephemeris information of all satellites that provide satellite signal coverage to the mobile base station in a future period of time, wherein the ephemeris information can reflect the position and speed of the corresponding satellite.

[0117] See also Figure 2E As shown in the example, before time T8, the mobile base station has satellite signal coverage, in the time period T8-T9, the mobile base station has no satellite signal coverage, and from time T9, the mobile base station has satellite signal coverage again. Since the orbit of the satellite is predictable, the coverage range and coverage duration of the satellite are also predictable. The satellite reference period can be inferred through the satellite's ephemeris information. Specifically, the geometric position of the satellite within a period of time can be inferred based on the satellite's ephemeris information, and then the coverage range of the satellite cell on the ground can be inferred. Correspondingly, Figure 2E In the example, the satellite reference period of the target satellite is before time T8 and after time T9.

[0118] Thus, the mobile base station determines the satellite reference time period corresponding to the location information through the satellite reference information and the location information of the mobile base station, reduces the processing resources of the core network equipment, and quickly obtains the satellite reference time period.

[0119] S120. The mobile base station sends a data transmission period to the mobile terminal.

[0120] The mobile base station may inform the mobile terminal of the determined data transmission period through broadcasting, Radio Resource Control (RRC) signaling, etc.

[0121] S130. The mobile terminal determines a target transmission strategy for the target uplink data within a data transmission period based on a preset value and a data volume of the target uplink data.

[0122] Among them, the preset value is a pre-configured number between 0-1, such as 0.6. The mobile terminal can reduce the comparison value of the data volume of the target uplink data in the data transmission period based on the preset value, thereby using SDT to transmit more uplink data.

[0123] The target transmission strategy may include SDT and transmission via traditional connection methods.

[0124] Among them, SDT can be used for the transmission of relatively scattered application data. The mobile terminal can use the unscheduled resources PUR (Preconfigured Uplink Resource) or RRC signaling to transmit a small amount of scattered application data without entering the connected state, thereby saving signaling overhead and improving the utilization of wireless resources.

[0125] In this embodiment, optionally, the mobile terminal determines a target transmission strategy for the target uplink data within the data transmission period based on a preset value and a data volume of the target uplink data, including:

[0126] When the product of the data volume of the target uplink data and the preset value is less than or equal to the preset data transmission threshold, the mobile terminal determines that the target transmission strategy of the target uplink data in the data transmission period is the first transmission strategy; when the product of the data volume of the target uplink data and the preset value is greater than the preset data transmission threshold, the mobile terminal determines that the target transmission strategy of the target uplink data in the data transmission period is the second transmission strategy.

[0127] The first transmission strategy is used to describe the transmission of small data, and the second transmission strategy is used to describe the data transmission between the mobile terminal and the mobile base station by establishing a connection.

[0128] The preset data transmission threshold may be pre-configured by the mobile base station. After the mobile base station configures the preset data transmission threshold, it may be transmitted to the mobile terminal via broadcasting, RRC signaling, or the like.

[0129] Thus, the mobile terminal can effectively determine the target transmission strategy of the target uplink data within the data transmission period based on the preset data transmission threshold and the product of the data volume of the target uplink data and the preset value.

[0130] In some embodiments, optionally, the data transmission period includes: a first period, the first period can be as follows: Figure 2C In the T0-T1 period shown, the preset values ​​include: a first value, such as 0.6, which can be configured by the mobile base station and transmitted to the mobile terminal through broadcasting, RRC signaling, etc.

[0131] The mobile terminal determines a target transmission strategy for the target uplink data within the data transmission period based on a preset value and the data volume of the target uplink data, including:

[0132] If the product of the data volume of the target uplink data in the first time period and the first numerical value is less than or equal to the preset first transmission threshold, the target transmission strategy of the target uplink data in the first time period is determined to be the first transmission strategy; if the product of the data volume of the target uplink data in the first time period and the first numerical value is greater than the preset first transmission threshold, the target transmission strategy of the target uplink data in the first time period is determined to be the second transmission strategy.

[0133] The mobile terminal can determine the target transmission strategy of the target uplink data in the first time period of the data transmission period, and can allocate corresponding transmission strategies to it in the first time period according to different transmission situations, which can effectively improve the data transmission efficiency between the mobile terminal and the mobile base station.

[0134] In some other embodiments, optionally, the data transmission period further includes: a second period, which can be as follows: Figure 2C In the T1-T2 period shown, the preset value also includes: a second value, the second value is 0.7, the second value can be configured by the mobile base station and transmitted to the mobile terminal through broadcasting, RRC signaling, etc.

[0135] The mobile terminal determines a target transmission strategy for the target uplink data within the data transmission period based on a preset value and the data volume of the target uplink data, including:

[0136] If the product of the data volume of the target uplink data in the second time period and the second numerical value is less than or equal to the preset second transmission threshold, the target transmission strategy of the target uplink data in the second time period is determined to be the first transmission strategy; if the product of the data volume of the target uplink data in the second time period and the second numerical value is greater than the preset second transmission threshold, the target transmission strategy of the target uplink data in the second time period is determined to be the second transmission strategy.

[0137] The mobile terminal can determine the target transmission strategy of the target uplink data in the second time period of the data transmission period, and can allocate corresponding transmission strategies for different transmission situations in the second time period, which can effectively improve the data transmission efficiency between the mobile terminal and the mobile base station.

[0138] In summary, the mobile terminal can select the corresponding target transmission strategy to transmit uplink data in two time periods within the data transmission period, so that the target uplink data can be quickly and effectively transmitted from the mobile terminal to the mobile base station, further improving the communication transmission efficiency between the mobile base station and the core network equipment.

[0139] For example, if the product of the data volume of the target uplink data in the first time period and the first numerical value is less than or equal to the preset first transmission threshold, it can be determined that the target transmission strategy of the target uplink data in the first time period is the first transmission strategy; if the product of the data volume of the target uplink data in the second time period and the second numerical value is less than or equal to the preset second transmission threshold, it can be determined that the target transmission strategy of the target uplink data in the second time period is the first transmission strategy.

[0140] If the product of the data volume of the target uplink data in the first time period and the first numerical value is less than or equal to the preset first transmission threshold, it can be determined that the target transmission strategy of the target uplink data in the first time period is the first transmission strategy. If the product of the data volume of the target uplink data in the second time period and the second numerical value is greater than the preset second transmission threshold, it can be determined that the target transmission strategy of the target uplink data in the second time period is the second transmission strategy.

[0141] If the product of the data volume of the target uplink data in the first time period and the first numerical value is greater than the preset first transmission threshold, it can be determined that the target transmission strategy of the target uplink data in the first time period is the second transmission strategy; if the product of the data volume of the target uplink data in the second time period and the second numerical value is less than or equal to the preset second transmission threshold, it can be determined that the target transmission strategy of the target uplink data in the second time period is the first transmission strategy.

[0142] If the product of the data volume of the target uplink data in the first time period and the first numerical value is greater than the preset first transmission threshold, it can be determined that the target transmission strategy of the target uplink data in the first time period is the second transmission strategy. If the product of the data volume of the target uplink data in the second time period and the second numerical value is greater than the preset second transmission threshold, it can be determined that the target transmission strategy of the target uplink data in the second time period is the second transmission strategy.

[0143] In addition, when the target transmission strategy is the second transmission strategy and the current moment is within a preset time period in the data transmission period, the mobile terminal can establish a communication connection with the mobile base station to facilitate sending target uplink data to the mobile base station based on the second transmission strategy.

[0144] Among them, the mobile base station may impose additional constraints on "entering the connected state through the traditional method", such as instructing the mobile terminal to establish an RRC connection with the mobile base station and enter the connected state within a preset time period before the end of the data transmission period, so as to avoid entering the connected state for too long, resulting in the mobile base station not receiving or not fully receiving the target uplink data transmitted by the mobile terminal through the connected state when communicating with the core network equipment during the satellite signal coverage period, and being unable to ensure that the corresponding uplink data is transmitted to the core network equipment through the satellite signal.

[0145] The mobile base station may notify the mobile terminal via an RRC message of data radio bearers available for data transmission. Specifically, the mobile terminal may be notified of which data radio bearers may be used for SDT transmission and which data radio bearers may be used for traditional connection state transmission.

[0146] S140. The mobile terminal sends target uplink data to the mobile base station based on the target transmission strategy.

[0147] As shown in the above example, during the data transmission period, when the mobile terminal determines that the target transmission strategy is the first transmission strategy, it can send the target uplink data to the mobile base station based on the SDT method. When it determines that the target transmission strategy is the second transmission strategy, it can send the target uplink data to the mobile base station through the traditional method of entering the connection state and establishing the bearer.

[0148] After the mobile base station receives the target uplink data sent by the mobile terminal, the method of this embodiment may further include:

[0149] When the mobile base station is not covered by satellite signals at the current moment, the mobile base station caches the target uplink data; when the mobile base station is covered by satellite signals at the current moment, the mobile base station sends the target uplink data to the core network device.

[0150] Among them, the mobile base station can determine whether there is satellite signal coverage in the location area of ​​the mobile base station at the current moment according to the satellite reference time period. When there is no satellite signal coverage, the target uplink data is cached, and when the location area of ​​the mobile base station is covered by satellite signals, the target uplink data is sent to the core network equipment to facilitate effective data transmission.

[0151] It should be noted that the preset second transmission threshold is greater than the preset first transmission threshold. When the data transmission period includes the first period and the second period, and the preset first transmission threshold corresponding to the first period is less than the preset second transmission threshold corresponding to the second period, if the mobile base station has no satellite signal coverage in the first period, the target uplink data transmitted by the mobile terminal in the first period is cached, and in the second period, the corresponding capacity determination threshold is increased (the second transmission threshold is greater than the first transmission threshold), so that the mobile terminal in the second period selectively adopts the method of establishing a connection state to transmit data to the mobile base station. Since it takes a certain time to establish a connection state, the mobile base station can timely transmit the cached target uplink data transmitted by the mobile terminal in the first period within the corresponding satellite signal coverage moment in the second period.

[0152] In the present embodiment, the mobile terminal is able to receive a data transmission period sent by a mobile base station, and based on a preset value and the data volume of the target uplink data, determine a target transmission strategy for the target uplink data within the data transmission period, and send the target uplink data to the mobile base station based on the target transmission strategy. Thus, the mobile terminal is able to determine the target transmission strategy for data transmission with the mobile base station based on the preset value and the data volume of the target uplink data, thereby effectively improving data transmission efficiency.
