Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] See Figure 1 , Figure 1 This is a flow chart of an embodiment of a method for transmitting positioning information provided by this application. Applied to a transmitting terminal, the method includes:

[0033] Step 11: Obtain several voice superframes to be sent.

[0034] In some embodiments, in the DMR / PDT digital wireless communication standard, which is a TDMA system, one frame (60 milliseconds) consists of two time slots (30 milliseconds), and one voice superframe consists of six voice frames, namely A, B, C, D, E and F voice frames. Figure 2 As shown, the transmitting terminal MS1 can send voice data to the receiving terminal MS2 in the period of A, B, C, D, E and F voice frames. A voice frame is a voice frame with a synchronization header (such as Figure 3 As shown), the middle 48 bits are synchronization series, used for frame synchronization, and the two sides are 108 bits of voice data; the other voice frames are voice frames with embedded signaling (such as Figure 4 As shown), the embedded signaling has 32 bits, and the LC voice header can be transmitted through the embedded signaling of 4 voice frames (as shown Figure 5 As shown, LC and checksum are forward error corrected by BPTC, and then interleaved by FEC. After interleaving, they are transmitted through the position of embedded signaling in 4 voice frames. The data format is as follows:

[0035] As shown in Table 1.

[0036]

[0037]

[0038] Table 1

[0039] In Table 1, PF (protect flag) represents a protection flag, Reserved represents a reserved or reserved flag, FLCO (Full Link Control Opcode) represents a full link control signaling operation code, when its value is 0b000000, it represents a group call voice LC, when its value is 0b000011, it represents an individual call voice LC, FID represents a feature ID, Service Option represents a service option, Group Address represents a group address, and Source Address represents a source address.

[0040] Step 12: According to a preset interval, a target voice superframe to be sent is selected from a number of voice superframes to be sent.

[0041] For example, the preset interval can be one interval or multiple intervals, which can be set according to the actual situation. Figure 6 The voice superframes to be sent include voice superframe 1, voice superframe 2, voice superframe 3, voice superframe 4, and voice superframe 5. The target voice superframe to be sent is selected every two voice superframes, and voice superframe 3 is used as the target voice superframe to be sent.

[0042] Step 13: Load the positioning information of the transmitting terminal into the position of the embedded signaling in the target voice superframe to be sent.

[0043] In some embodiments, combined Figure 5 To explain: Figure 5 As shown, the location information of the transmitting terminal is loaded at the position of the embedded signaling originally used to load the LC voice header in the target voice superframe to be sent.

[0044] Step 14: Send several voice superframes to be sent to the receiving terminal.

[0045] In some embodiments, after several to-be-transmitted voice superframes are sent to a receiving terminal, the receiving terminal can determine that the information is positioning information based on the corresponding information in the position of the embedded signaling. The receiving terminal can then parse the positioning information to calculate the positional relationship between the transmitting terminal and the receiving terminal, such as distance and direction.

[0046] In this embodiment, by loading the positioning information of the transmitting terminal at the position belonging to the embedded signaling in the target voice superframe to be sent, the voice superframe is used to carry the positioning information of the transmitting terminal, and then the voice superframe is sent to the receiving terminal, thereby realizing the transmission of the positioning information of the transmitting terminal to the receiving terminal in the absence of a dispatching station, facilitating the subsequent determination of the positions of the transmitting terminal and the receiving terminal.

[0047] See Figure 7 , Figure 7 This is a flow chart of another embodiment of the method for transmitting positioning information provided by the present application. Applied to a transmitting terminal, the method includes:

[0048] Step 71: Acquire several voice superframes to be sent.

[0049] Step 72: In response to the positioning information being single-frame positioning information, a target voice superframe to be sent is selected from a plurality of voice superframes to be sent according to a preset interval.

[0050] In this embodiment, the positioning information may be single-frame positioning information.

[0051] The single-frame positioning information includes a protection flag, a reserved or retained flag, a full-link control signaling operation code, longitude, and latitude. Specific details are shown in Table 2:

[0052]

[0053] Table 2

[0054] In Table 2, PF represents a protection flag, Reserved represents a reserved or reserved flag, FLCO represents a full-link control signaling operation code, and when its value is 0b110000, it represents single-frame positioning information, Longitude represents longitude, and Latitude represents latitude.

[0055] Step 73: Load the single frame positioning information at the position of the embedded signaling in the target voice superframe to be sent.

[0056] Step 74: Send several voice superframes to be sent to the receiving terminal.

[0057] Steps 73 to 74 have the same or similar technical solutions as any embodiment of the present application and are not described in detail here.

[0058] In this embodiment, by loading the single-frame positioning information of the transmitting terminal at the position belonging to the embedded signaling in the target voice superframe to be sent, the voice superframe is used to carry the single-frame positioning information of the transmitting terminal, and then the voice superframe is sent to the receiving terminal, thereby realizing the transmission of the positioning information of the transmitting terminal to the receiving terminal in the absence of a dispatching station, facilitating the subsequent determination of the positions of the transmitting terminal and the receiving terminal.

[0059] See Figure 8 , Figure 8 This is a flow chart of another embodiment of the method for transmitting positioning information provided by the present application. Applied to a transmitting terminal, the method includes:

[0060] Step 81: Acquire several voice superframes to be sent.

[0061] Step 82: In response to the positioning information being dual-frame positioning information, a first target voice superframe to be sent and a second target voice superframe to be sent are selected from a plurality of voice superframes to be sent according to a preset interval.

[0062] In this embodiment, the positioning information may be dual-frame positioning information, and the positioning information of the transmitting terminal may be reflected in two frames.

[0063] Step 83: Load the start frame of the positioning information into the position of the embedded signaling in the first target voice superframe to be sent; and load the end frame of the positioning information into the position of the embedded signaling in the second target voice superframe to be sent.

[0064] The start frame includes a protection flag, a reserved or retained flag, a full-link control signaling operation code, an encryption flag, a position error, power, battery level, signal strength, and a destination address. See Table 3 for details:

[0065]

[0066]

[0067]

[0068] Table 3

[0069] In Table 3, PF represents a protection flag, Reserved represents a reserved or retained flag, FLCO represents a full-link control signaling operation code, and when its value is 0b110001, it indicates the start frame of the dual-frame positioning information. C represents an encryption flag, PositionError represents a position error, Power represents power, Battery Level represents battery level, RSSI represents signal strength, and TargetAddress represents the destination address.

[0070] The end frame includes a protection flag, a reserved or retained flag, a full-link control signaling operation code, longitude, and latitude. See Table 4 for details:

[0071]

[0072]

[0073] Table 4

[0074] In Table 4, PF represents a protection flag, Reserved represents a reserved or retained flag, FLCO represents a full-link control signaling operation code, and when its value is 0b110011, it indicates the end frame of the dual-frame positioning information, Longitude represents longitude, and Latitude represents latitude.

[0075] Step 84: Send several voice superframes to be sent to the receiving terminal.

[0076] Step 84 has the same or similar technical solution as any embodiment of the present application and will not be described in detail here.

[0077] In this embodiment, by loading the dual-frame positioning information of the transmitting terminal at the position belonging to the embedded signaling in the target voice superframe to be sent, the voice superframe is used to carry the dual-frame positioning information of the transmitting terminal, and then the voice superframe is sent to the receiving terminal, thereby realizing the transmission of the positioning information of the transmitting terminal to the receiving terminal in the absence of a dispatching station, facilitating the subsequent determination of the positions of the transmitting terminal and the receiving terminal.

[0078] See Figure 9 , Figure 9 FIG. 1 is a flow chart of another embodiment of a method for transmitting positioning information provided by the present application. Applied to a receiving terminal, the method includes:

[0079] Step 91: Receive several voice superframes to be sent from the transmitting terminal.

[0080] Step 92: When it is detected that the target voice superframe to be sent is included in the plurality of voice superframes to be sent, the positioning information of the transmitting terminal is parsed from the target voice superframe to be sent; wherein the positioning information is loaded into the position of the embedded signaling in the target voice superframe to be sent.

[0081] For example, if the FLCO value parsed in the embedded signaling is 0b000000, it indicates a group call voice LC. If it is 0b000011, it indicates an individual call voice LC. If it is 0b110000, it indicates single-frame positioning information. If it is 0b110001, it indicates the start frame of dual-frame positioning information. If it is 0b110011, it indicates the end frame of dual-frame positioning information. In other words, the FLCO can be used to identify whether positioning information or an LC voice header exists in the voice superframe, and then respond accordingly. For example, if positioning information is identified, the corresponding positioning information can be parsed.

[0082] In some embodiments, after parsing the positioning information of the transmitting terminal from the target voice superframe to be sent, refer to Figure 10 , the method of this application also includes the following process:

[0083] Step 101: Calculate the positioning information of the transmitting terminal and the positioning information of the receiving terminal to obtain the distance between the transmitting terminal and the receiving terminal and the orientation of the transmitting terminal relative to the receiving terminal.

[0084] Step 102: Display the positional relationship between the transmitting terminal and the receiving terminal via a coordinate diagram and / or text.

[0085] like Figure 11 As shown, the distance and direction between the transmitting terminal and the receiving terminal are displayed on the receiving terminal in combination with the coordinate diagram and text display.
