Fig. 1 is showing of the channel coding method of multi-rate speech business according to an embodiment of the invention Meaning property flow chart.The embodiment of Fig. 1 can be performed by the code device of transmitting terminal.

110, determine the rate mode of speech business, wherein speech business includes at least two class subflows.

Upper voice traffic can be AMR-WB business or AMR-NB business, the enforcement of the present invention Example is not limited to this, such as, upper voice traffic can also be use many subflows transmission means other from Adapt to multi-rate speech business.When upper voice traffic is AMR-NB, above-mentioned at least two class subflows A class subflow, B class subflow and C class subflow can be included.When upper voice traffic is AMR-WB, Above-mentioned at least two class subflows can include A class subflow and B class subflow.

Embodiments of the invention can be by detecting certain class subflow (example of speech business in a speech frame Such as, A class subflow) the length of packet determine the speed of speech business, premise is by different phonetic The packet of this kind of subflow of speed is set to different length.Embodiments of the invention are to determining voice industry The rate mode of business is not restricted, for example, it is also possible to according to high-level signaling (such as, RRC signaling) Notice determines the speed of speech business.

120, according between rate mode and at least two class subflows and the channel coding method of speech business Corresponding relation, is that at least two class subflows determine channel coding method, and wherein, every kind of rate mode is at least Corresponding relation is there is between two class subflows and channel coding method.

It is understood that for the rate mode of different phonetic business in embodiments of the invention, all kinds of There is corresponding relation between subflow and channel coding method, such as, for the speech business of every kind of speed, The chnnel coding side of subflow that can be differently configured in the transport channel parameters that transformat combination is corresponding Formula, in order to the different subflows of transmission in different transmission channels are carried out chnnel coding.Alternatively, it is possible to To arrange the channel coding method of the combination of at least two class subflows, in order to transmission in same channel extremely Few two class subflows carry out chnnel coding.Above-mentioned corresponding relation can pass through high-level signaling (such as, RRC letter Make) configuration, such as by RRC signaling, this corresponding relation is sent to base station by radio network controller And subscriber equipment；Additionally, this corresponding relation can also be in transmitting terminal (such as, the base station side of speech business Or user equipment side) arrange.Here, the bit that rate mode uses for indicating AMR speech business Speed, different rate modes is corresponding to different bit rates.

Channel coding method can be convolution coding mode or Turbo code coded system, such as, Under a kind of rate mode, can use convolution coding mode to arrange A class subflow, B class subflow uses Turbo code coded system, and under another kind of rate mode, A class subflow and B class subflow can be set All use convolution coding mode, or the combination that can arrange A class subflow and B class subflow uses Turbo code coded system, etc..

130, channel coding method determined by employing carries out chnnel coding at least two class subflows.

After the rate mode determining speech business, can according to above-mentioned corresponding relation determine above-mentioned extremely The channel coding method that few two class subflows are corresponding.Such as, under certain rate mode, convolutional code is used to compile Code mode carries out chnnel coding to A class subflow, uses Turbo code coded system that B class subflow is carried out letter Road encodes.

In 120, the speed at the rate mode deictic word sound business of speech business is positioned at first rate district Time interior, select convolution coding mode as the channel coding method of at least two class subflows；In voice industry When the speed of the rate mode deictic word sound business of business is positioned at the second rate period, select convolution coding Mode, as the channel coding method of a part of subflow at least two class subflows, selects Turbo code coding Mode is as the channel coding method of another part subflow at least two class subflows.Wherein, first rate Interval is the rate period less than first threshold, and the second rate period is little more than or equal to first threshold In the rate period equal to Second Threshold.Such as, if first threshold is a, Second Threshold is b, then First rate interval is that (0, a), the second rate period is [a, b].

According to embodiments of the invention, multi-rate speech business is wideband adaptive multi-rate speech business, At least two class subflows include A class subflow and B class subflow, the most in 120, in the speed of speech business When the speed of rate pattern deictic word sound business is less than first threshold, select convolution coding mode conduct respectively A class subflow and the coded system of B class subflow；Speed at the rate mode deictic word sound business of speech business When rate is less than or equal to Second Threshold more than or equal to first threshold, select convolution coding mode as A class The channel coding method of stream, and select Turbo code coded system as the chnnel coding side of B class subflow Formula.

Such as, A class subflow can be the A class subflow in wideband adaptive multi-rate speech business, important Property is the highest, A class subflow can be circulated redundancy check (Cyclical before chnnel coding Redundancy Check, CRC), in order to improve the reliability of data, then to the A through CRC Class subflow carries out chnnel coding.

According to embodiments of the invention, first threshold is 12.65kb/s, and Second Threshold is 23.85kb/s.

Such as, in the case of the rate mode of AMR speech business is 6.60kb/s or 8.85kb/s, Select 1/3 convolution coding mode (or 1/2 convolution coding mode) as A class subflow respectively and The coded system of B class subflow, the rate mode in AMR speech business is 12.65kb/s, 14.25kb/s, In the case of 15.58kb/s, 18.25kb/s, 19.85kb/s, 23.05kb/s or 23.85kb/s, select 1/3 convolution coding mode, as the channel coding method of A class subflow, selects 1/3Turbo code (Turbo Code, TC) mode (or 1/2Turbo code mode) is the channel coding method of B class subflow.
