Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
At present, PDT (Professional Digital Trunking, Digital Clustering) in communication system, source device obtains VoP after speech audio is carried out compressed encoding, real speech frame and empty speech frame is had in described VoP, real speech frame, by what obtain after the word audio compressed encoding in speech audio, is the Frame carrying Word message in speech audio; Empty speech frame obtains by after the speech gaps compressed encoding in speech audio, is do not carry any Word message, only represents the Frame of speech audio Chinese word interval.Wherein, source device can be mobile terminal in digital clustering communication system or base station, and target device also can be mobile terminal in digital clustering communication system or base station.Method, the Apparatus and system of provided by the present invention kind of data information transfer not only can be applied in PDT system, can also be applied in other narrowband systems such as digital cluster communication (Digital Mobi le Radio, DMR),
Fig. 1 is the waveform of one section of speech audio, pause place between each syllable of speech audio, and there is speech gaps at each punctuate place, and these gaps can continue tens even hundreds of milliseconds usually.Therefore, after speech audio compressed encoding gained VoP in, the empty speech frame much not carrying any Word message can be comprised.Source device by comprise sky speech frame VoP by transmission to target device, because the empty speech frame in VoP does not carry any Word message, but but occupy channel resource, cause channel resource utilance low.
Embodiment one
In order to solve the low problem of above-mentioned channel resource utilance, the invention provides a kind of method of data information transfer, Fig. 2 is method transmit leg scene one flow chart of a kind of data information transfer of the present invention, and embodiment one is applied to the source device launching speech audio, and described method comprises:
Step 201: the speech audio of receipt of call side's input is carried out compressed encoding and obtained VoP.
Step 202: employing voice-activation detecting method detects the empty speech frame in described VoP.
Described in foregoing, after source device receives the speech audio of calling party input, compressed encoding obtains the VoP comprising real speech frame and empty speech frame.The Word message of speech audio is carried in real speech frame, can not carry extra data message again, and empty speech frame is mainly in order to the real speech frame in interval, does not carry any useful data message, therefore, the newly-increased data message chosen in advance can be added in empty speech frame.
Need opening voice to activate measuring ability to detect the empty speech frame in VoP, comprising:
Employing frequency domain energy detection method or short-time energy averaging method detect the empty speech frame in described VoP.
Generally, empty speech frame is lower than the energy of real speech frame, based on this principle, above-mentioned three kinds of detection methods can be adopted empty speech frame in VoP to be detected.
Here it should be noted that, when detecting the empty speech frame in VoP, be not limited in above-mentioned three kinds of detection methods to detect the empty speech frame in VoP, other can also be adopted the detection method of sky speech frame can be detected, repeat no more here.
Step 203: when sky speech frame being detected, adds frame identification marking in the default identified region in the data payload region of described empty speech frame.
Step 204: adopt preset channel coded system to encode to the newly-increased data message chosen in advance.
Step 205: the default bearing area of the newly-increased data message after coding being added to the data payload region of described empty speech frame obtains newly-increased Frame.
Sky speech frame detected from VoP after, first add frame identification marking at the default identified region in the data payload region of empty speech frame.An empty speech frame obtains a newly-increased Frame after with the addition of frame identification marking and the newly-increased data message after encoding.Empty speech frame detected by step 202 is a lot, in had sky speech frame, frame identification marking and the multiple newly-increased Frame of newly-increased data message acquisition can be added respectively, also only can add frame identification marking and newly-increased data message respectively in the empty speech frame of a part.Therefore, in the VoP received by target device, not only there is the newly-increased Frame that with the addition of newly-increased data message, also have real speech frame, also may be free speech frame.Frame identification marking is that target device is for identifying the newly-increased Frame in VoP, according to whether carrying in Frame frame identification marking, target device can identify whether this Frame is newly-increased Frame, thus newly-increased Frame can be identified, extract the newly-increased data message carried in the newly-increased Frame frame identified.
Here it should be noted that, the default identified region in the data payload region of empty speech frame refers to the region of the interpolation frame identification marking pre-set in data payload region.Wherein, the length presetting identified region specifically can set according to practical application, is not limited in the 16bit that the embodiment of the present invention provides.Further, default identified region is generally arranged on the foremost in data payload region.Such as: if presetting identified region is 16bit, then 0 to the 16bit in data payload region is set to default identified region, then in 0 to the 16bit region in data payload region, adds frame identification marking.After target device receives VoP, the Frame in VoP is detected one by one, whether carry frame identification marking in the default identified region detecting each VoP, the Frame carrying frame identification marking is identified as newly-increased Frame.
The transmit leg of speech audio can choose the newly-increased data message that will be sent to target device in advance, by described newly-increased data message input source equipment.Source device adopts preset channel coded system to encode to the newly-increased data message chosen in advance, and obtain the newly-increased data message after coding, the newly-increased data message after described coding comprises the newly-increased data message and check bit chosen in advance.
In actual applications, the described newly-increased data message to choosing in advance adopts preset channel coded system to carry out coding to comprise:
Hamming code, reed solomon product code RS or loop coding are carried out to the newly-increased data message chosen in advance.
Here it should be noted that, in practical application, be not limited in and adopt above-mentioned three kinds of coded systems to encode to newly-increased data message, other coded system can also be adopted, repeat no more here.
The default bearing area of the newly-increased data message after coding being added to the data payload region of sky speech frame obtains newly-increased Frame, and described default bearing area is that in data payload region, other regions beyond the default identified region of frame identification marking are added in removing.The structural representation in the data payload region of the newly-increased Frame that Fig. 3 generates for transmit leg scene one, as shown in Figure 3, frame identification marking is arranged on the foremost in data payload region, newly-increased data message after coding is arranged on after data payload region, comprises newly-increased data message and check bit.Generally, default bearing area is arranged in data payload region presets after identified region, and namely default bearing area is other regions in an empty speech frame except default identified region.Such as: the data payload region of an empty speech frame is 72bit, and default identified region accounts for 16bit, then presetting bearing area is 56bit, 0 to the 16bit in data payload region is set to default identified region, 17bit to 72bit is set to default bearing area.
Become newly-increased Frame after newly-increased data message after empty speech frame with the addition of frame identification marking and coding, the newly-increased position of Frame residing in VoP is identical with described empty speech frame.Such as: to suppose in VoP that the 5th and the 7th Frame are all sky speech frames, become the first newly-increased Frame after newly-increased data message after with the addition of frame identification marking and coding to the 5th Frame, after the newly-increased data message after with the addition of frame identification marking and coding to the 7th Frame, become the second newly-increased Frame.The position that then the first newly-increased Frame is residing in VoP is the position of the 5th Frame, and the second newly-increased position of Frame residing in VoP is the position of the 7th Frame.It can thus be appreciated that although become newly-increased Frame after with the addition of frame identification marking and the newly-increased data message after encoding to empty speech frame, in VoP, the order of Frame does not change.
Certainly, in actual applications, default identified region is not limited in the 16bit described in embodiment, can also arrange the default identified region being less than 16bit or being greater than 16bit according to actual needs, and accordingly, the size of bearing area is preset in adjustment.
Step 206: by comprise described newly-increased Frame VoP by transmission to the target device receiving described speech audio.
Source device by VoP by transmission to target device, at least comprise real speech frame and newly-increased Frame in VoP, also likely comprise a part of empty speech frame.
Fig. 4 is method transmit leg scene two flow chart of a kind of data information transfer of the present invention, 0 to the 16bit that identified region is the data payload region of described empty speech frame is preset described in scene two, when carrying out hamming code to the newly-increased data message chosen in advance, described method comprises:
Step 401: the speech audio of receipt of call side's input is carried out compressed encoding and obtained VoP.
Step 402: employing voice-activation detecting method detects the empty speech frame in described VoP.
Step 403: when sky speech frame being detected, adds frame identification marking in 0 to the 16bit in the data payload region of described empty speech frame.
Step 404: hamming code is carried out to described newly-increased data message, obtain comprise 32bit increase the coding of data message and 24bit check bit newly after newly-increased data message.
Step 405: the 17bit to the 72bit data message after the coding of 56bit being added into the data payload region of described empty speech frame obtains newly-increased Frame.
The structural representation in the data payload region of the newly-increased Frame that Fig. 5 generates for transmit leg scene two, as shown in Figure 5.0 to the 16bit in the data payload region of newly-increased Frame is frame identification marking, and 17bit to 72bit is the newly-increased data message after coding.Wherein, in the region of 17bit to 72bit, 17bit to 48bit is the newly-increased data message of 32bit, and 49bit to 72bit is the Hamming check bit of 24bit.
Step 406: by comprise described newly-increased Frame VoP by transmission to the target device receiving described speech audio.
Transmit leg scene two is similar with transmit leg scene one implementation method, with reference to the description of the execution mode of transmit leg scene one, repeats no more here.
Fig. 6 is method recipient scene one flow chart of a kind of data information transfer of the present invention, and be applied to the target device receiving speech audio, described method comprises:
Step 601: receive source device by the VoP of transmission, include newly-increased Frame in described VoP.
Described VoP at least comprises newly-increased Frame and real speech frame, also likely comprises sky Frame.Described newly-increased Frame carries and other data messages different with speech audio chosen in advance.
Described newly-increased Frame is that the speech audio inputted by source device receipt of call side carries out compressed encoding acquisition VoP, employing voice-activation detecting method detects the empty speech frame in described VoP, when sky speech frame being detected, in the default identified region in the data payload region of described empty speech frame, add frame identification marking; Preset channel coded system is adopted to encode to the newly-increased data message chosen in advance, the Frame that the default bearing area of the newly-increased data message after coding being added to the data payload region of described empty speech frame obtains.Similar with transmit leg scene one herein, with reference to the description of transmit leg scene one, repeat no more here.
Step 602: whether the default identified region detecting the data payload region of the Frame in described VoP carries frame identification marking, if so, performs step 603; If not, step 606 is performed.
Step 603: described Frame is identified as newly-increased Frame, adopts the default decoding process data message to the default bearing area in the data payload region of described newly-increased Frame corresponding with described preset channel coded system to carry out decoding and obtains newly-increased data message.
Recipient's target device receives in VoP, detects one by one the Frame in described VoP, and whether the default identified region detecting the data payload region of each Frame carries frame identification marking.Described default identified region is that the default identified region of source device interpolation frame identification marking is identical, such as: when the default identified region of source device interpolation frame identification marking is 0 to the 16bit in data payload region, the default identified region that target device detects also is 0 to the 16bit in the data payload region of Frame.
When target device does not detect frame identification marking in the default identified region in the data payload region of Frame, this Frame may be real speech frame, also may be sky speech frame, now, perform step 606, obtain the next Frame in VoP, the default identified region demonstration detecting the data payload region of next Frame carries frame identification marking.
When target device the data payload region of Frame default identified region frame identification marking detected, then this Frame is identified as newly-increased Frame.The default decoding process data message to the default bearing area in the data payload region of the newly-increased Frame that identify corresponding with described preset channel coded system is then adopted to decode.The default decoding process that target device adopts is corresponding with the preset channel coded system that source device adopts.Illustrate: if source device adopts hamming code mode; Then target device adopts Hamming decoding process; If source device adopts RS coded system, then target device adopts RS decoding process; If source device adopts loop coding mode, then target device adopts iterative decoding mode.
Target device adopt preset that decoding process carries out decoding to as if the data message of the default bearing area in the data payload region of newly-increased Frame that identifies.Default bearing area is that in newly-increased Frame, in data payload region, other regions beyond identified region are preset in removing.Presetting in bearing area what add is newly-increased data message after coding, comprises newly-increased data message and check bit.
Obtain newly-increased data message after decoding to the data message of the default bearing area in the data payload region of described newly-increased Frame, described speech data information is other the data message except voice data information.Illustrate: the default bearing area in the data payload region of described newly-increased Frame is 56bit, comprise the newly-increased data message of 32bit and the check bit of 24bit.Then decode to the data message of described default bearing area, can obtain the newly-increased data message of 32bit, the check bit of 24bit is mainly used in verifying described information data information when decoding.
Step 604: replace described newly-increased Frame with empty speech frame.
Step 605: the speech audio obtaining calling party input after decoding decompress(ion) is carried out to the described VoP newly-increased Frame being replaced to sky speech frame.
After carrying out the newly-increased data message of decoding acquisition to the default bearing area in the data payload region of the newly-increased Frame detected, need to replace described newly-increased Frame with empty speech frame.When the newly-increased Frame detected by target device has multiple, after needing that the newly-increased data message of decoding acquisition is carried out to the default bearing area in the data payload region of each newly-increased Frame, all newly-increased Frames detected are replaced with empty speech frame all respectively.
Be understandable that, after source device receives the speech audio of calling party data, compressed encoding is carried out to described speech audio and obtains VoP, detect the empty speech frame in described VoP, the newly-increased data message added in the empty speech frame detected after frame identification marking and coding obtains newly-increased Frame.That is, in VoP received by target device, detected newly-increased Frame with the addition of the newly-increased data message acquisition after frame identification marking and coding by empty speech frame, the speech audio of calling party input is obtained in order to not affect VoP decoding decompress(ion), need to carry out short covering frame occupy-place process at detected newly-increased Frame place, namely need to replace all newly-increased Frames detected with empty speech frame.Decoding decompress(ion) is carried out to the described VoP newly-increased Frame being replaced to sky speech frame, empty speech frame converts the gap in speech audio between language and characters to, real speech frame converts the language and characters in speech audio to, obtains the speech audio of calling party input.
Step 606: obtain the next Frame in described VoP, return and perform step 602, whether the default identified region detecting the data payload region of the next Frame in described VoP carries frame identification marking.
Scheme provided by the present invention compared with prior art, the difference of core is, in prior art, after target device receives VoP, speech audio can only be obtained after decoding decompress(ion), and in technical scheme provided by the present invention, because the newly-increased data message with the addition of frame identification marking and coding in empty speech frame after obtains newly-increased Frame, newly-increased Frame is comprised in the VoP that source device sends to target device, target device can detect newly-increased Frame according to frame identification marking from received VoP, extract the newly-increased data message in described newly-increased Frame.Target device can not only obtain speech audio, can also obtain the extra newly-increased data message different from speech audio.Namely the VoP sent at channel not only carries speech data information, also carries newly-increased data message, improves the utilance of channel.
Provide the instantiation that utilizes the transmission method of data message provided by the present invention in PDT communication system below:
Fig. 7 is a kind of data information transfer method of the present invention example scenario flow chart, in embodiment two, source device is base station, and target device is hand platform, newly-increased data message is field intensity RSSI (Received SignalStrength Indication) value, and described method comprises:
Step 701: the speech audio of base station receipt of call side input is carried out compressed encoding and obtained VoP, and employing voice-activation detecting method detects the empty speech frame in described VoP.
Step 702: when sky speech frame being detected, frame identification marking is added in base station in the default identified region in the data payload region of described empty speech frame.
Step 703: base station adopts preset channel coded system to encode to RSSI value; The default bearing area of the newly-increased data message after coding being added to the data payload region of described empty speech frame obtains newly-increased Frame.
Step 704: base station by comprise described newly-increased Frame VoP by transmission to the hand platform receiving described speech audio.
Step 705: hand platform receives the VoP of source device by transmission.
Step 706: whether the default identified region that hand platform detects the data payload region of the Frame in described VoP carries frame identification marking, if so, performs step 707; If not, step 709 is performed.
Step 707: described Frame is identified as newly-increased Frame, hand platform adopts the default decoding process data message to the default bearing area in the data payload region of described newly-increased Frame corresponding with described preset channel coded system to carry out decoding and obtains RSSI value, replaces described newly-increased Frame with empty speech frame.
Step 708: hand platform obtains the speech audio of calling party input after carrying out decoding decompress(ion) to the described VoP newly-increased Frame being replaced to sky speech frame.
Step 709: hand platform obtains the next Frame in described VoP, return and perform step 706, whether the default identified region detecting the data payload region of the next Frame in described VoP carries frame identification marking.
As can be seen from above-mentioned example, base station is while sending speech audio to hand platform, the RSSI value of hand platform is added in the empty speech frame that in speech audio, the gap of language and characters generates, obtain the newly-increased Frame carrying RSSI value, the VoP including newly-increased Frame is sent to hand platform by base station.Hand platform extracts described RSSI value from the newly-increased Frame the VoP detected, according to the transmitting power of described RSSI value adjustment self.Such as, when the RSSI value that hand platform extracts from newly-increased Frame is stronger, the transmitting power that can reduce hand platform saves electricity.
Owing to substituted for all newly-increased Frame detected in VoP with empty speech frame, do not affect the speech audio that VoP decoding decompress(ion) obtains, namely can not affect normal call flow, extra newly-increased data message can also be obtained.Improve the utilance of channel.
