Embodiment
In order to make those skilled in the art more clearly understand technical scheme of the present invention, below in conjunction with the safe transmission method of embodiment speech data of the present invention.
The safe transmission method of speech data of the present invention comprises the steps:
First, the multiplexor of voice data transmission is set up.
In the gauge outfit of VoP, front 8 positions define the version of speech data, type and subtype successively, and be followed successively by thereafter and retain position, issue, sequence number and payload length, last position is load contents.
In one embodiment, define Four types in type bit, such as Control Cooling is " 00 ", and management type is " 01 ", and data type is " 10 ", and user's speech data type that selectivity sets is as " 11 ".
By setting speech data type in the gauge outfit of VoP, one or more speech data passage can be set up in same transmission, thus distinguish the instruction such as speech data control, setting, state needing to transmit in time or transmit not in time.Like this, when transmitting the speech data needing to transmit in time, can not by the impact of other VoP, prioritised transmission.
In one embodiment, the periodic report method of speech data is realized.
When the type bit of gauge outfit be set as " 00 " namely Control Cooling time, further setting subtype position.
In a preferred embodiment, subtype position comprises " confirmation " subtype, this position is set as " 00 ", the type represents needs speech data receiving terminal to confirm VoP to the passback of speech data transmitting terminal, VoP comprises the information of speech data receiving terminal, comprising the buffer size of speech data receiving terminal.
In a preferred embodiment, subtype that subtype position comprises " buffering area consumes report ", this position is set as " 01 ", now, speech data receiving terminal passes the VoP of buffering area consumption information back to speech data transmitting terminal, this VoP comprises the information of speech data receiving terminal, comprising the turn around time and buffering area consumption etc. of speech data receiving terminal.
In a preferred embodiment, subtype that subtype position comprises " speech data consumption report ", this position is set as " 10 ", now, speech data receiving terminal passes the VoP of speech data consumption information back to speech data transmitting terminal, this VoP comprises the information of speech data receiving terminal, comprising the turn around time and speech data consumption etc. of speech data receiving terminal.
The buffering area consumption beamed back by speech data receiving terminal or speech data consumption, speech data transmitting terminal can adjust the generation speed of speech data or the speed of notice speech data receiving terminal adjustment speech data consumption, thus makes speech data transmitting terminal produce the speed sync of speech data and speech data receiving terminal consumption speech data.
In one embodiment, the delay response method of speech data is realized.
When the type bit of gauge outfit is set as " 01 ", when being management type, setting subtype position further.When group type bit is set as " searching request " subtype " 0000 ", it is then the search VoP of the broadcast of transmitting terminal, thus the receiving terminal in search network, unique sequence number can be had in the gauge outfit of this VoP, option, length, data equipotential in load contents, can be comprised.When receiving terminal feedback search VoP, the sequence number of its VoP sent can identical with search VoP.Wherein, can determine at random or determine by system the time that delay VoP sends, thus the probability that minimizing VoP collides.
In one embodiment, realize the rear of speech data to arrive but preferential bus connection method.
When the type bit of gauge outfit be set as " 01 " namely management type time, further setting subtype position.
When group type bit is set as " line request " subtype, such as " 0001 ", transmitting terminal sends the VoP that issue is zero, thus set up line, then receiving terminal can send there is " line response " subtype, such as " 0015 " VoP to transmitting terminal, wherein can set unique issue, this issue non-zero.Wherein, when having set up line between transmitting terminal and receiving terminal, transmitting terminal and receiving terminal can re-establish a new line, thus need not interrupt existing line.
When group type bit is set as " interrupting line request " subtype, such as " 0010 ", transmitting terminal or receiving terminal send VoP after line is set up, and are used for interrupting existing line.If when another receiving terminal is wanted to interrupt this existing line, then this receiving terminal first must receive the search VoP that transmitting terminal sends, just can send " interrupting line request " of requiring to interrupt existing line to the transmitting terminal of existing line and receiving terminal afterwards, and then set up line with transmitting terminal.
The advantage of the method is, any one device on same network all temporarily can interrupt existing line between receiving terminal and transmitting terminal, and preferential and receiving terminal sets up new line, and line rule can be made like this to simplify most.Need to illustrate, do not consider internet security in the network transport mechanism of the present embodiment, thus avoid the account management demand of user; If consider internet security, then need to arrange fail safe rule in its lower floor's communications protocol.
In one embodiment, the periodic broadcast search response method of speech data is realized.
Receiving terminal to the periodic broadcast search response VoP on one's own initiative of all transmitting terminals on consolidated network, thus can notify that all transmitting terminals exist this receiving terminal on network.
When the type bit of gauge outfit be set as " 10 ", namely data type time, further in subtype position, set " encryption (E) ", " compression (C) ", " retransmitting (R) " and " complete zero (Z) " position successively.
When encrypted bits is set as 1, show that this VoP is encrypted voice data bag, can a bit of in part of speech packet in an encrypted voice data stream or part of speech packet, thus accelerate language data process speed and reduce the load of processor, especially in speech data, although just local cypher, listener-in has been difficult to the sound not hearing speech data.Transmitting terminal can selection cycle ground by speech data packet encryption, such as every five speech data packet encryptions are once, also can Choice encryption VoP immediately.
The front two of VoP " load " position represents the length starting position and the encrypted voice data encrypted respectively; If position is 0, length is the length of whole speech data, then represent that whole speech data is all encrypted.
When " compression " position is set as 1, represent that this VoP is the VoP compressed.If need to encrypt and compress simultaneously, preferably first compress and encrypt again.Because adopt local cypher method in the present invention, the object of overall encryption so just can be reached.
When " re-transmission " position is set as 1, represent that this VoP is attached most importance to new transmitted VoP.
When " complete zero " position is set as 1, represent that this VoP is quiet data.In the gauge outfit of this VoP, payload length represents the length of this quiet data, because quiet data can be deleted, therefore when in audio data stream during one section of quiet data, can the gauge outfit of only transmitting audio data bag, thus save bandwidth.
Above embodiment is only for describing the technical scheme of the safe transmission method of speech data of the present invention; be not used in restriction the present invention; those skilled in the art without departing from the scope of the present invention; can obtain various modification and combination, therefore protection scope of the present invention is as the criterion with claims.
