[0045] In order to solve the technical problem in the prior art that private network terminals cannot use RTK positioning technology to achieve high-precision positioning functions, the present application provides a real-time dynamic differential data sending device that can enable private network terminals to use RTK positioning technology to achieve high-precision positioning functions.

[0046] Figure 1 A flowchart of a method for sending real-time dynamic differential data is provided in an embodiment of the present application. In one embodiment, the method includes:

[0047] S101. Determine a target frequency resource from multiple frequency resources.

[0048] It should be noted that a base station has multiple channel machines, each corresponding to a frequency resource. A frequency resource can be a frequency point or a frequency band. A target channel machine is determined from the multiple channel machines, where the target channel machine corresponds to the target frequency resource.

[0049] S102: Divide each time period corresponding to the target frequency resource into a control time slot and a service time slot.

[0050] The control time slot is used to transmit control signaling.

[0051] It should be noted that when there are no other services, the base station sends C_ALOHA control signaling in the control timeslot on the target frequency resource, with the Reserved bit in the C_ALOHA control signaling set to 0. The base station also sends IDLE messages in the service timeslot on the target frequency resource. Accordingly, when there are no other services, the private network terminal receives control signaling in the control timeslot on the target frequency resource and does not receive messages in the service timeslot on the target frequency resource.

[0052] It should be noted that C_ALOHA control signaling is defined in the ETSI TS102 361-4 standard protocol.

[0053] S103: Send target control signaling to the private network terminal via the control time slot on the target frequency resource.

[0054] The target control signaling is used to indicate that the service time slot is used to send RTK differential data.

[0055] In one embodiment, the target control signaling includes C_ALOHA control signaling. When the base station needs to send RTK differential data to the private network terminal, the base station sends C_ALOHA control signaling to the private network terminal on the target frequency resource to inform the private network terminal that the base station will subsequently send RTK differential data on the target frequency resource through the service time slot. The value of the Reserved bit of the C_ALOHA control signaling is 1. The private network terminal receives the C_ALOHA control signaling from the base station on the target frequency resource and parses it to obtain the value of the Reserved bit of the C_ALOHA control signaling. If the value of the Reserved bit of the C_ALOHA control signaling is 1, the private network terminal begins to receive RTK differential data from the service time slot on the target frequency resource. If the value of the Reserved bit of the C_ALOHA control signaling is 0, the private network terminal stops receiving RTK differential data from the service time slot on the target frequency resource.

[0056] In another embodiment, the target control signaling includes C_BCAST control signaling. The C_BCAST control signaling is defined in the ETSI TS102 361-4 standard protocol. When the base station needs to send RTK differential data to the private network terminal, the base station sends C_BCAST control signaling to the private network terminal on the target frequency resource to inform the private network terminal that the base station will then send RTK differential data through the service time slot on the target frequency resource. The value of the Announcement_type bit of the C_BCAST control signaling is 0b01000. The private network terminal receives the C_BCAST control signaling from the base station on the target frequency resource, and parses it to obtain the value of the Announcement_type bit of the C_BCAST control signaling. If the value of the Announcement_type bit of the C_BCAST control signaling is 0b01000, the private network terminal starts to receive RTK differential data from the service time slot on the target frequency resource. If the value of the Announcement_type bit of the C_CBAST control signaling is not equal to 0b01000, the private network terminal stops receiving RTK differential data from the service time slot on the target frequency resource.

[0057] It should be noted that the target control signaling can be other service control signaling to instruct the base station to send RTK differential data through the service time slot on the target frequency resource. This application does not impose any restrictions here.

[0058] It should be noted that both the service timeslot and the control timeslot correspond to the same frequency. Therefore, the private network terminal does not need to switch to another channel machine to receive RTK differential data. This effectively prevents the private network terminal from losing connection due to switching to another channel machine to receive RTK differential data and being unable to return to the target channel machine to receive control signals from the base station.

[0059] S104: Send real-time dynamic differential data to the private network terminal via the service time slot on the target frequency resource.

[0060] It should be noted that the base station sends RTK differential data to the private network terminal via the service time slot on the target frequency resource. If the base station does not need to send RTK differential data to the private network terminal, the base station sends C_ALOHA control signaling to the private network terminal via the control time slot on the target frequency resource to inform the private network terminal that the base station will not send RTK differential data to it in the future. The value of the Reserved bit of the C_ALOHA control signaling is 0. Alternatively, the base station sends C_BCAST control signaling to the private network terminal via the control time slot on the target frequency resource to inform the private network terminal that the base station will not send RTK differential data to it in the future. The value of the Announcement_type bit of the C_BCAST control signaling is not equal to 0b01000.

[0061] An embodiment of the present application provides a method for sending real-time dynamic differential data. The method includes: determining a target frequency resource from a plurality of frequency resources; dividing each time period corresponding to the target frequency resource into a control time slot and a service time slot; sending a target control signaling to a private network terminal through the control time slot on the target frequency resource, wherein the target control signaling is used to indicate that the service time slot is used to send real-time dynamic differential data; and sending the real-time dynamic differential data to the private network terminal through the service time slot on the target frequency resource. It can be seen that the present application determines the target frequency resource from a plurality of frequency resources and divides each time period corresponding to the target frequency resource into a service time slot and a control time slot. The target control signaling is transmitted through the control time slot on the target frequency resource, and the real-time dynamic differential data is transmitted through the service time slot on the target frequency resource. It can be seen that the private network terminal can receive real-time dynamic differential data through the service time slot on the target frequency resource to achieve a high-precision positioning function of the private network terminal.

[0062] In one embodiment, the sending the real-time dynamic differential data to the private network terminal through the service time slot on the target frequency resource includes:

[0063] a. Construct target data burst frames based on real-time dynamic differential data.

[0064] The target data burst frame includes a Data Packet Format (DPF) field, with the reserved bits of the DPF set to a preset value. The preset value indicates that the target data burst frame includes RTK differential data. It should be noted that the service time slot can be used to transmit RTK differential data or other service data, such as voice data.

[0065] To distinguish RTK differential data from other service data, the base station uses the RTK differential data to construct a target data burst frame, wherein the header of the target data burst frame is a DPF. According to the ETSI TS102 361-1 V1.4.5 standard protocol, the length of the DPF field is 4 bits. The DPF values ​​of 0b0000, 0b0001, 0b0010, 0b0011, 0b1101, 0b1110, or 0b1111 have clear meanings in the ETSI TS102 361-1 standard protocol. Therefore, embodiments of the present application can distinguish RTK differential data from other service data by setting the preset value to the value of other non-standard protocols. For example, the preset value can be set to 0b0100. Of course, the preset value can also be set to the value of other non-standard protocols. For example, the preset value can be set to 0b0101. This application does not impose any restrictions on this.

[0066] b. Send target data burst frames to the private network terminal through the service time slot on the target frequency resource.

[0067] The base station sends a target data burst frame to the private network terminal on the target frequency resource. Upon receiving the target data burst frame from the base station, the private network terminal extracts the DPF field in the target data burst frame and determines whether the DPF field value indicates that the target data burst frame's payload is RTK differential data. If so, the terminal extracts the RTK differential data from the target data burst frame.

[0068] See also Figure 2 , Figure 2 This is a flow chart of a method for receiving real-time dynamic differential data provided by an embodiment of the present application. In one embodiment, the method uses a private network terminal and includes:

[0069] S201. Receive target control signaling from a base station via a target frequency resource.

[0070] Among them, each time period corresponding to the target frequency resource includes a control time slot and a service time slot. The control time slot is used to transmit target control signaling, and the target control signaling is used to instruct the base station to send RTK differential data to the private network terminal through the service time slot on the target frequency resource.

[0071] It should be noted that the target control signaling is the same as the target control signaling in S1, and will not be described in detail in this application.

[0072] S202: Receive real-time dynamic differential data through a service time slot on a target frequency resource.

[0073] It should be noted that the above embodiments have already described in detail how the private network terminal receives RTK differential data from the base station, and this application will not elaborate on this.

[0074] In one embodiment, the receiving the real-time dynamic differential data through the service time slot on the target frequency resource includes:

[0075] A. Receive the target data burst frame from the base station through the service time slot on the target frequency resource.

[0076] Wherein, the target data burst frame includes a DPF field;

[0077] It should be noted that the target data burst frame has the same format as that of the target data burst frame in step a. Detailed description is omitted for brevity.

[0078] B. Determine whether the reserved bit in the data packet format field is equal to the preset value. If so, proceed to step C.

[0079] The preset value is used to indicate that the target data burst frame includes RTK differential data. As can be seen from the above embodiment, the header of the target data burst frame is the DPF. According to the ETSI TS102 361-1 V1.4.5 standard protocol, the DPF field is 4 bits long. The DPF values ​​of 0b0000, 0b0001, 0b0010, 0b0011, 0b1101, 0b1110, or 0b1111 have clear meanings in the ETSI TS102 361-1 standard protocol. In the embodiments of the present application, it can be defined that when the DPF value is 0b0100, the target data burst frame includes RTK differential data. Of course, the preset value can also be set to a value for other non-standard protocols. For example, the preset value can be set to 0b0101. This application does not impose any restrictions on this.

[0080] C. Extract real-time dynamic differential data from the target data burst frame.

[0081] For example, when the value of the DPF field of the target data burst frame is 0b0100, the target data burst frame includes RTK differential data. Therefore, the private network terminal can extract the RTK differential data from the target data burst frame.

[0082] It should be noted that RTK differential data includes positioning information. The base station can obtain this positioning information through Beidou. Of course, the base station can also obtain this positioning information through GPS. This application does not impose any restrictions here.
