[0045] To address the technical problem that private network terminals cannot achieve high-precision positioning using RTK positioning technology in existing technologies, this application provides a real-time dynamic differential data transmission device that enables private network terminals to achieve high-precision positioning using RTK positioning technology.

[0046] Figure 1 This is a flowchart illustrating a real-time dynamic differential data transmission method provided in an embodiment of this application. In one embodiment, the method includes:

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

[0048] It should be noted that a base station has multiple channel devices, each corresponding to a frequency resource. This frequency resource can be a frequency point or a frequency band. The target channel device is determined from these multiple channel devices, with the target channel device corresponding to a target frequency resource.

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

[0050] Among them, 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 through this control time slot on the target frequency resource, where the Reserved bit of the C_ALOHA control signaling is 0. The base station sends IDLE messages through the service time slot on the target frequency resource. Correspondingly, when there are no other services, the private network terminal receives control signaling from this control time slot on the target frequency resource, but does not receive messages from this service time slot on the target frequency resource.

[0052] It should be noted that the 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 through the control time slot on the target frequency resource.

[0054] Among them, the target control signaling is used to indicate the service time slot for sending 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 send RTK differential data through the service time slot on the target frequency resource. The Reserved bit of the C_ALOHA control signaling is set to 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. If the Reserved bit of the C_ALOHA control signaling is 1, the private network terminal begins receiving RTK differential data from the service time slot on the target frequency resource. If 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. 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 subsequently send RTK differential data on the target frequency resource through service time slots. The value of the Announcement_type bit in 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. If the value of the Announcement_type bit in the C_BCAST control signaling is 0b01000, the private network terminal begins receiving RTK differential data from service time slots on the target frequency resource. If the value of the Announcement_type bit in the C_CBAST control signaling is not equal to 0b01000, the private network terminal will stop 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 transmit RTK differential data through service time slots on the target frequency resources. This application does not impose any restrictions on this.

[0058] It should be noted that the service time slots and control time slots correspond to the same frequency. Therefore, the private network terminal does not need to switch to other channel devices to receive RTK differential data, effectively avoiding the situation where the private network terminal cannot return to the target channel device to receive control signaling from the base station after switching to other channel devices to receive RTK differential data, which could lead to the private network terminal losing connection.

[0059] S104. Send real-time dynamic differential data to the private network terminal through 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 service time slots on the target frequency resources. If the base station does not need to send RTK differential data to the private network terminal, it sends a C_ALOHA control signaling message to the private network terminal via a control time slot on the target frequency resources to inform the private network terminal that the base station will not send RTK differential data to it. In this case, the Reserved bit of the C_ALOHA control signaling message is 0. Alternatively, the base station sends a C_BCAST control signaling message to the private network terminal via a control time slot on the target frequency resources to inform the private network terminal that the base station will not send RTK differential data to it. In this case, the Announcement_type bit of the C_BCAST control signaling message is not equal to 0b01000.

[0061] This application provides a method for transmitting real-time dynamic differential data. The method includes: determining a target frequency resource from multiple frequency resources; dividing each time period corresponding to the target frequency resource into a control time slot and a service time slot; sending target control signaling to a private network terminal via the control time slot on the target frequency resource, the target control signaling instructing the service time slot to transmit real-time dynamic differential data; and transmitting the real-time dynamic differential data to the private network terminal via the service time slot on the target frequency resource. Therefore, this application determines a target frequency resource from multiple frequency resources and divides each time period corresponding to the target frequency resource into a service time slot and a control time slot. Target control signaling is transmitted via the control time slot on the target frequency resource, and real-time dynamic differential data is transmitted via the service time slot on the target frequency resource. Thus, the private network terminal can receive real-time dynamic differential data via the service time slot on the target frequency resource, thereby achieving high-precision positioning functionality.

[0062] In one embodiment, sending the real-time dynamic differential data to the private network terminal via 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 reserved bits in the DPF equal to a preset value. This preset value indicates that the target data burst frame includes RTK differential data. It should be noted that service time slots can be used to send RTK differential data, or they can be used to send other service data, such as voice data.

[0065] To distinguish RTK differential data from other service data, the base station uses RTK differential data to construct target data burst frames, where the header of the target data burst frame is a DPF (Distributed Packet Frame). According to the ETSI TS102 361-1 V1.4.5 standard protocol, the DPF field is 4 bits long. The DPF values ​​0b0000, 0b0001, 0b0010, 0b0011, 0b1101, 0b1110, or 0b1111 have specific meanings in the ETSI TS102 361-1 standard protocol. Therefore, in this application embodiment, the difference between RTK differential data and other service data can be distinguished by setting a preset value to other non-standard protocol values. For example, the preset value can be set to 0b0100. Of course, the preset value can also be set to other non-standard protocol values. For example, the preset value can be set to 0b0101. This application does not impose any limitations on this.

[0066] b. Send target data burst frames to private network terminals via service time slots on the target frequency resources.

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

[0068] Please see Figure 2 , Figure 2 This is a flowchart illustrating a real-time dynamic differential data receiving method provided in an embodiment of this application. In one embodiment, the method utilizes a private network terminal and includes:

[0069] S201, Receive target control signaling from the base station through target frequency resources.

[0070] 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 that in S1. This application will not elaborate further here.

[0072] S202. Receive real-time dynamic differential data through service time slots on the target frequency resources.

[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. This application will not repeat that description here.

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

[0075] A. Receive target data burst frames from the base station via service time slots on the target frequency resources.

[0076] 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 the target data burst frame in step a. This will not be elaborated further here.

[0078] B. Determine if the reserved bits in the data packet format field are equal to the preset value. If yes, proceed to step C.

[0079] The preset value is used to indicate that the target data burst frame includes RTK differential data. As shown in the above embodiments, the header of the target data burst frame is a DPF (Digital Packet Filter). According to the ETSI TS102361-1 V1.4.5 standard protocol, the DPF field is 4 bits long. The DPF values ​​0b0000, 0b0001, 0b0010, 0b0011, 0b1101, 0b1110, or 0b1111 have explicit meanings in the ETSI TS102361-1 standard protocol. In this application embodiment, a DPF value of 0b0100 can be defined as indicating that the target data burst frame includes RTK differential data. Of course, the preset value can also be set to other non-standard protocol values. For example, the preset value can be set to 0b0101. This application does not impose any limitations on this.

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

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

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

[0087] The second transmitting unit 304 is used to transmit the real-time dynamic differential data to the private network terminal through the service time slot on the target frequency resource.

[0088] In one embodiment, the second sending unit 304 is specifically used to construct a target data burst frame based on the real-time dynamic differential data. The target data burst frame includes a data packet format field, and the reserved bits of the data packet format field are equal to a preset value.
