[0034] Example 1

[0035] Figure 1 This is a flowchart illustrating a BeiDou short message transmission method provided in Embodiment 1 of the present invention. This method is applicable to the promotion of BeiDou short messages. The method can be executed by a BeiDou short message transmission device, which can be implemented by software and / or hardware and is generally integrated into an electronic device.

[0036] like Figure 1 As shown, the BeiDou short message transmission method provided in Embodiment 1 of the present invention includes the following steps:

[0037] S110. Determine the total amount of data for the BeiDou short message to be launched.

[0038] The "BeiDou short message to be launched" can be any BeiDou short message to be launched. BeiDou short message communication refers to the short message communication system of the BeiDou system, which enables direct two-way information transmission between BeiDou ground terminals and BeiDou satellites / ground monitoring stations via satellite signals. Communication uses short messages (similar to SMS messages) as the basic unit of transmission and is a functional feature of the BeiDou satellite navigation system. The "total data" can be the total length of the BeiDou short message to be launched, which can be the total length of the data to be sent after being converted to binary.

[0039] In this embodiment, before transmitting the BeiDou short message, the BeiDou short message to be transmitted can be processed to obtain the total data length of the BeiDou short message and determine the total amount of data.

[0040] S120. Based on the communication level of the Beidou-3 short message smart card, the total amount of data is processed by different framing strategies to obtain data with different frame lengths.

[0041] Among them, the BeiDou-3 short message smart card can be a smart card used for BeiDou-3 short message communication services. Communication level refers to the communication level that the BeiDou-3 short message smart card can perform. Smart cards with different communication levels can have different transmission powers, and the classification method of communication levels can be set according to actual conditions. For example, communication levels can be divided into first, second, third, fourth, and fifth communication levels. Different framing strategies can be the transmission strategies for data with different frame lengths. Different framing strategies can divide a segment of BeiDou short message data into multiple data frames of different lengths. Frame length refers to the length of each frame in the data frame.

[0042] In this embodiment, the maximum frame length data that the communication card can send can be determined based on the communication level of the BeiDou-3 short message smart card, and the total data volume can be divided into data of different frame lengths according to the framing strategy. It is understood that in a multi-card system, different communication card levels can be selected based on different data lengths and communication rates.

[0043] S130. Determine the transmission duration corresponding to the data of different frame lengths.

[0044] The transmission duration can be the time required to transmit data, and the transmission duration varies depending on the frame length.

[0045] In this embodiment, after obtaining data of multiple different frame lengths, the transmission duration required for each different frame length can be calculated based on the transmission rate corresponding to the different frame lengths.

[0046] S140. Determine the transmission energy corresponding to the data of different frame lengths based on the selected transmission power, transmission efficiency, and transmission duration corresponding to the data of different frame lengths.

[0047] Transmission power can be the power used to transmit data of different frame lengths, and the range of transmission power can be determined according to the actual satellite access requirements. For example, depending on the actual satellite access requirements, different upper limit transmission power P can include: 2W (P1), 3W (P2), 5W (P3), and 10W (P4). Transmission efficiency can be the conversion efficiency corresponding to the transmission power; different transmission powers have different transmission efficiencies. Transmission energy can be the energy consumed to transmit data.

[0048] In this embodiment, the transmission power and transmission efficiency corresponding to data with different frame lengths are different. After determining the transmission duration corresponding to data with different frame lengths, the transmission power consumption required to transmit the data with different frame lengths in actual operation can be determined first based on the transmission power and transmission efficiency corresponding to different frame lengths. Then, the transmission energy corresponding to the transmission data can be calculated based on the transmission power consumption and transmission duration.

[0049] S150. Select the data corresponding to the target frame length whose transmission energy is less than or equal to the power supply energy of the transmitting device, and transmit according to the transmission power and transmission rate corresponding to the data of the target frame length.

[0050] The power supply energy of the transmitting equipment can be the standard power supply energy of the transmitting equipment, and the transmitting equipment can be a device that transmits BeiDou short messages. The target frame length can be data of different frame lengths that meet the transmission conditions. The transmission conditions can be the conditions for transmitting data of different frame lengths. In this embodiment, the transmission conditions can refer to data whose transmission energy is less than or equal to the power supply energy of the transmitting equipment.

[0051] In this embodiment, the transmission energy E corresponding to data of different frame lengths j Less than or equal to the power supply energy E of the transmitting device s Only then can data of different frame lengths be used as data of the target frame length, and transmitted according to the transmission power and transmission rate corresponding to the target frame length. This ensures that the energy consumed to transmit the target frame length is within the power supply level of the transmitting equipment, guarantees the use of the most appropriate transmission power for each BeiDou short message transmission, reduces the transmission power of BeiDou short message transmission, saves transmission energy, and improves transmission stability.

[0052] This invention provides a BeiDou short message transmission method, comprising: determining the total amount of data in the BeiDou short message to be transmitted; applying different framing strategies to the total amount of data based on the communication level of the BeiDou-3 short message smart card to obtain data of different frame lengths; determining the transmission duration corresponding to the data of different frame lengths; determining the transmission energy corresponding to the data of different frame lengths based on the selected transmission power, transmission efficiency, and the transmission duration corresponding to the data of different frame lengths; selecting data of a target frame length whose corresponding transmission energy is less than or equal to the power supply energy of the transmitting device, and transmitting the data according to the transmission power and transmission rate corresponding to the data of the target frame length. This method applies different framing strategies to the BeiDou short message to be transmitted, obtains data of different frame lengths, and selects an appropriate transmission power for transmission, thus achieving low-power processing of BeiDou short messages.

[0053] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0054] In one embodiment, the BeiDou-3 short message smart card includes five communication levels, with different numbers of transmission bits and different transmission rates corresponding to different communication levels;

[0055] The first communication level corresponds to the first number of transmitted bits, and the first communication level corresponds to the first transmission rate;

[0056] The second communication level corresponds to the second number of transmitted bits, and the second communication level corresponds to the first transmission rate;

[0057] The third communication level corresponds to the third number of transmitted bits, and the third communication level corresponds to the second transmission rate;

[0058] The fourth communication level corresponds to the fourth number of transmitted bits, and the fourth communication level corresponds to the third transmission rate;

[0059] The fifth communication level corresponds to the fifth number of transmitted bits, and the fifth communication level corresponds to the fourth transmission rate;

[0060] Wherein, the first number of transmitted bits is less than the second number of transmitted bits, which is less than the third number of transmitted bits, which is less than the fourth number of transmitted bits, which is less than the fifth number of transmitted bits, and the first transmission rate is less than the second transmission rate, which is less than the third transmission rate, which is less than the fourth transmission rate.

[0061] The number of transmitted bits can be the number of bits transmitted per unit time, and the transmission rate can be the amount of data transmitted through the data path per unit time. Different transmission rates correspond to different transmission uptime. The first, second, third, fourth, and fifth communication levels are the five communication levels corresponding to the BeiDou-3 short message smart card. The first number of transmitted bits can be the number of transmitted bits corresponding to the first communication level, the second number of transmitted bits can be the number of transmitted bits corresponding to the second communication level, the first transmission rate can be the transmission rate corresponding to the first and second communication levels, the third number of transmitted bits and the second transmission rate can be the number of transmitted bits and the transmission rate corresponding to the third communication level, the fourth number of transmitted bits and the third transmission rate can be the number of transmitted bits and the transmission rate corresponding to the fourth communication level, and the fifth number of transmitted bits and the fourth transmission rate can be the number of transmitted bits and the transmission rate corresponding to the fifth communication level.

[0062] In this embodiment, different communication levels can correspond to different transmission bit counts and transmission rates. The first and second communication levels correspond to the first transmission rate, while the third, fourth, and fifth communication levels correspond to the second, third, and fourth transmission rates, respectively.

[0063] For example, the first, second, third, and fourth transmission rates can be 2kbps, 4kbps, 8kbps, and 16kbps, respectively, corresponding to different upper transmission power limits, namely 2W (P1), 3W (P2), 5W (P3), and 10W (P4). Correspondingly, the first, second, third, fourth, and fifth transmission bit counts can be 692 bits, 1835 bits, 3883 bits, 7979 bits, and 14000 bits, respectively. Depending on the transmission power, the suitable transmission rate for the first and second communication levels can be 2kbps, the suitable transmission rate for the third communication level can be 4kbps, the suitable transmission rate for the fourth communication level can be 8kbps, and the suitable transmission rate for the fifth communication level can be 16kbps.

[0064] In one embodiment, the different framing strategies include at least:

[0065] First framing strategy: The total amount of data is divided into frames of first data, and the frame length of the first data is less than or equal to the second number of transmission bits;

[0066] Second framing strategy: The total amount of data is divided into frames of second data, and the frame length of the second data is greater than the second number of transmitted bits and less than or equal to the third number of transmitted bits;

[0067] Third framing strategy: The total amount of data is divided into frames of third data, and the frame length of the third data is greater than the third number of transmitted bits and less than or equal to the fourth number of transmitted bits;

[0068] Fourth framing strategy: The total amount of data is divided into fourth data, and the frame length of the fourth data is greater than the fourth data and less than or equal to the fifth transmission bit number;

[0069] Fifth framing strategy: The total amount of data is divided into fifth data, and the frame length of the fifth data is greater than the number of fifth transmission bits.

[0070] The first, second, third, fourth, and fifth framing strategies can be different framing strategies determined based on the frame length of the data. The first data can be the data obtained by executing the first framing strategy, the second data can be the data obtained by executing the second framing strategy, the third data can be the data obtained by executing the third framing strategy, the fourth data can be the data obtained by executing the fourth framing strategy, and the fifth data can be the data obtained by executing the fifth framing strategy.

[0071] In this embodiment, different framing strategies can be determined based on the different number of transmitted bits, and the total amount of data can be divided into data of different frame lengths according to different framing strategies. For example, based on the different number of transmitted bits, the frame lengths of the first data, second data, third data, fourth data, and fifth data can be divided as follows: the frame length of the first data ≤ 1835 bits, 1835 bits ≤ the frame length of the second data ≤ 3883 bits, 3883 bits ≤ the frame length of the third data ≤ 7979 bits, 7979 bits ≤ the frame length of the fourth data ≤ 14000 bits, and the frame length of the fifth data > 14000 bits.

[0072] Example 2

[0073] Figure 2 This is a flowchart illustrating a BeiDou short message transmission method according to Embodiment 2 of the present invention. Embodiment 2 is an optimization based on the above embodiments. For details not covered in this embodiment, please refer to Embodiment 1.

[0074] like Figure 2 As shown in Embodiment 2 of the present invention, a BeiDou short message transmission method includes the following steps:

[0075] S210. Determine the total amount of data for the BeiDou short message to be launched.

[0076] S220. Based on the communication level of the Beidou-3 short message smart card, the total amount of data is divided into different frame strategies to obtain data with different frame lengths.

[0077] S230. Calculate the transmission duration corresponding to different frame lengths of data based on the data with the frame length corresponding to the corresponding communication level and the transmission rate corresponding to the corresponding communication level.

[0078] In this embodiment, for each frame length of data m, the transmission duration T of each frame length of data m can be calculated based on the transmission rate corresponding to the corresponding communication level and the frame length of the data.

[0079] For example, if the communication level is a first communication level or a second communication level, then the transmission rate is the first transmission rate: 2kbps, and the transmission duration is... If the communication level is level three, then the transmission rate is level two: 4kbps, and the transmission duration is... If the communication level is level four, then the transmission rate is level three: 8kbps, and the transmission duration is... If the communication level is level 5, then the transmission rate is level 4: 16kbps, and the transmission duration is...

[0080] S240. Determine the transmission energy corresponding to the data of different frame lengths based on the selected transmission power, transmission efficiency, and transmission duration corresponding to the data of different frame lengths.

[0081] S250: Select the data corresponding to the target frame length whose transmission energy is less than or equal to the power supply energy of the transmitting device, and transmit according to the transmission power and transmission rate corresponding to the data of the target frame length.

[0082] The second embodiment of the present invention provides a BeiDou short message transmission method, which further calculates the transmission duration corresponding to different frame lengths of data based on the data with the frame length corresponding to the corresponding communication level and the transmission rate corresponding to the corresponding communication level, thereby enabling the calculation of the transmission duration required for smart cards with different communication levels to transmit BeiDou short messages.

[0083] In one embodiment, determining the transmission duration corresponding to the fifth data for the fifth frame segmentation strategy among the different frame segmentation strategies includes:

[0084] The number of transmissions and the remaining data are obtained by calculating the quotient of the total data volume and the fifth transmission bit number corresponding to the fifth communication level; the ratio of the fifth transmission bit number to the fourth transmission rate corresponding to the fifth communication level is calculated; the transmission duration corresponding to the fifth data is obtained by multiplying the number of transmissions by the ratio.

[0085] The number of launches can be the number of times the data needs to be launched, and the remaining data can be the data excluding the data that has already been launched.

[0086] In this embodiment, when the data to be transmitted is the fifth data, it indicates that the total amount of data to be transmitted exceeds the maximum number of transmittable bits. In this case, the fifth data can be framed for separate transmission. Specifically, the quotient of the total data amount m and the fifth data transmission bit count can be calculated. Rounding down, we obtain a quotient N and a remainder (i.e., the remaining data). N is the number of transmissions required to transmit the total amount of data m. The time required to transmit each data transmission is calculated based on the fifth transmission bit count and the fourth transmission rate.

[0087]

[0088] Therefore, the transmission duration for N data transmissions can be calculated as: T = N * T5. For the remaining data, we can iterate to m, and for m, we can continue to execute different framing strategies to obtain data of different frame lengths. For data exceeding the fifth transmission bit count, it needs to be transmitted N+1 times consecutively.

[0089] In one embodiment, the final data length corresponding to the remaining data is determined, and the remaining data is transmitted according to the transmission power and transmission duration corresponding to the final data length.

[0090] The final data length can be the frame length of the remaining data.

[0091] In this embodiment, the final data length of the remaining data can be calculated, and the corresponding transmission rate can be determined based on the transmission power corresponding to the final data length. The transmission duration of the remaining data can be calculated, and the remaining data can be transmitted according to the corresponding transmission power. For example, if the remaining data m ≤ 1835 bits, the data can be transmitted according to the corresponding transmission power of 2W, and the transmission duration can be calculated according to the first transmission rate. For the remaining data, this embodiment can return to step S220 to continue execution, or the final data length of the remaining data can be determined by other methods.

[0092] In one embodiment, determining the transmission energy corresponding to the data of different frame lengths based on the selected transmission power, transmission efficiency, and transmission duration corresponding to the data of different frame lengths includes:

[0093] The transmission power consumption is obtained by calculating the ratio of the selected transmission power to the corresponding transmission efficiency. The transmission energy corresponding to the data of different frame lengths is obtained by multiplying the transmission power consumption by the transmission duration corresponding to the data of different frame lengths.

[0094] The transmission power consumption can be the transmission power that takes into account losses.

[0095] In this embodiment, since the conversion efficiency of transmission power is not 100% in actual operation, it is necessary to calculate the actual transmission power consumption based on the transmission power and its corresponding transmission efficiency, and calculate the transmission energy required to transmit data of different frame lengths based on the transmission power consumption and the transmission duration of data of different frame lengths.

[0096] For example, Figure 3 This is a flowchart illustrating a BeiDou short message transmission method according to an embodiment of the present invention, as shown below. Figure 3 As shown, after calculating the total data volume m of the BeiDou short messages to be sent, different framing strategies can be implemented to obtain data of different frame lengths, and the transmission duration T corresponding to different frame lengths can be calculated. Since the transmission efficiency η differs under different transmission powers P, it is necessary to calculate the transmission power consumption corresponding to different transmission powers. And according to P diss Calculate the transmission energy corresponding to data of different frame lengths

[0097] Example 3

[0098] Figure 4 This is a schematic diagram of a BeiDou short message transmitting device provided in Embodiment 3 of the present invention. The device is applicable to the promotion of BeiDou short messages. The device can be implemented by software and / or hardware and is generally integrated into electronic devices.

[0104] The transmission module 350 is used to select data of a target frame length whose corresponding transmission energy is less than or equal to the power supply energy of the transmission device, and to transmit the data according to the transmission power and transmission rate corresponding to the target frame length.

[0105] This embodiment provides a BeiDou short message transmitting device, comprising: a first determining module 310, used to determine the total amount of data in the BeiDou short message to be transmitted; a processing module 320, used to perform different framing strategies on the total amount of data based on the communication level of the BeiDou-3 short message smart card to obtain data of different frame lengths; a second determining module 330, used to determine the transmission duration corresponding to the data of different frame lengths; a third determining module 340, used to determine the transmission energy corresponding to the data of different frame lengths based on the selected transmission power, transmission efficiency, and the transmission duration corresponding to the data of different frame lengths; and a transmitting module 350, used to select data of a target frame length whose corresponding transmission energy is less than or equal to the power supply energy of the transmitting device, and transmit it according to the transmission power and transmission rate corresponding to the data of the target frame length. This device performs different framing strategies on the BeiDou short message to be transmitted, obtains data of different frame lengths, and selects an appropriate transmission power for transmission, thus achieving low-power processing of BeiDou short messages.

[0106] Furthermore, the Beidou-3 short message smart card includes five communication levels, with different numbers of transmission bits and different transmission rates corresponding to different communication levels;

[0107] The first communication level corresponds to the first number of transmitted bits, and the first communication level corresponds to the first transmission rate;

[0108] The second communication level corresponds to the second number of transmitted bits, and the second communication level corresponds to the first transmission rate;

[0109] The third communication level corresponds to the third number of transmitted bits, and the third communication level corresponds to the second transmission rate;

[0110] The fourth communication level corresponds to the fourth number of transmitted bits, and the fourth communication level corresponds to the third transmission rate;

[0111] The fifth communication level corresponds to the fifth number of transmitted bits, and the fifth communication level corresponds to the fourth transmission rate;

[0112] Wherein, the first number of transmitted bits is less than the second number of transmitted bits, which is less than the third number of transmitted bits, which is less than the fourth number of transmitted bits, which is less than the fifth number of transmitted bits, and the first transmission rate is less than the second transmission rate, which is less than the third transmission rate, which is less than the fourth transmission rate.

[0119] Furthermore, the second determining module 330 includes:

[0120] The transmission duration corresponding to different frame lengths is calculated based on the frame length data corresponding to the corresponding communication level and the transmission rate corresponding to the corresponding communication level.

[0121] Furthermore, for the fifth frame segmentation strategy among the different frame segmentation strategies, determining the transmission duration corresponding to the fifth data includes:

[0122] The number of transmissions and the remaining data are obtained by calculating the quotient of the total amount of data and the number of fifth transmission bits corresponding to the fifth communication level;
