Problems solved by technology

[0005] Therefore, in the prior art, during the entire voice service process, the voice data always occupies the receiving time slot of the receiving party and the transmitting time slot of the transmitting party, so the transmission of location information cannot be performed during the entire voice call process.
However, in the actual process of using professional wireless communication e

Example Embodiment

[0040] In the present invention, the position information header contains 12 BIT data, respectively defined as Table 1:

[0041]

[0042] The set information header is divided into 3 rows, each row contains 4 BIT data, that is, 3*4 row and column data. The row data uses hamming (7, 4, 3) for forward error correction, and the column uses simple parity to form 4 *7 (28bits) row and column data, such as Figure 17 . The position information header occupies the 28bit of the voice frame embedded in the 32bits area, and the remaining 4bits are filled with 0 to form a 32bits data area. The data is filled in the interleaving pattern from top to bottom and left to right of the block, such as Figure 18 . The information filling containing the position information block is filled according to the information in Table 1, and the data block protection mode is set according to the frame data type (FT). The data content sent each time is sent in the order of the slave address information, ma...

Abstract

The invention relates to a method for transmitting position information in a voice service. The method comprises the following steps: after continuously transmitting first-group voice of 20ms*N at a sending end, replacing voice data in a preset first 20ms time period by position information data and specific identification and sending, wherein the N is larger than or equal to 20; continuously transmitting second-group voice of 20ms*N, replacing preset voice data in a second 20ms time period in a voice super frame by the position information data and specific identification and sending, wherein the N is larger than or equal to 20; and so on, sending all data; at a receiving end, after continuously obtaining the first-group voice of 20ms*N, obtaining the position information data and the specific identification in the preset first 20ms time period in the voice super frame and processing, wherein the N is larger than or equal to 20; after continuously obtaining the second-group voice of 20ms*N, obtaining the position information data and the specific identification in the preset second 20ms time period in the voice super frame and processing, wherein the N is larger than or equal to 20; and so on, receiving all data. The method for transmitting the position information in the voice service, which is disclosed by the invention, has the advantages that the position information data is simultaneously transmitted in a voice communication process when a PDT (photodynamic therapy) device or a DMR (deuteron magnetic resonance) device is used.

Description

technical field [0001] The invention relates to a method for simultaneously transmitting voice and position information in a professional wireless communication terminal or system, in particular to a method for simultaneously transmitting voice and position information in DMR / PDT equipment. Background technique [0002] In the prior art, a TDMA frame of professional wireless communication consists of a 30ms sending BURST and a 30ms receiving BURST. In the voice service transmission process, six consecutive TDMA frames form a superframe for voice transmission, with a length of 360ms , which are numbered from "A" to "F" in turn. Since a TDMA frame takes up 60ms and only 30ms is used for transmission, the 60ms voice in a TDMA frame must be transmitted within 30ms of sending BURST, such as figure 1 shown. [0003] In professional wireless communication, speech frame A is a synchronous speech frame, which can be identified according to the synchronous characteristic symbol; the ...
