Embodiment
Fig. 1 is the schematic diagram of legacy cellular communication network 100.Legacy cellular communication network 100 comprises cell phone 102a and 102b.Cell phone 102a communicates by letter with 106b by bi-directional RF (RF) link 106a with 104b with base station 104a respectively with 102b.Particularly, cell phone 102a communicates by letter by wireless RF link 106a with base station 104a, and cell phone 102b communicates by letter by wireless RF link 106b with base station 104b.Each base station 104a, 104b can communicate by letter simultaneously with a plurality of cell phones.
As shown in Figure 1, each base station 104a, 104b are connected to wireless switching center (MSC) 108a, 108b.MSC 108a can be connected to a plurality of base stations and a plurality of other MSC.Similarly, MSC 108b can be connected to a plurality of base stations and a plurality of other MSC.MSC 108a, 108b are connected to PSTN (PSTN) 110 with base station 104a, 104b.By this way, MSC 108a, 108b provide the connectivity between mobile phone 102a, 102b and the PSTN 110.PSTN 110 can comprise dwelling house and commercial voice and data network.
The structure of legacy cellular communication network 100 allows cell phone 102a and other cellular telephone communication, comprises cell phone 102b.Legacy cellular communication network 100 is also realized cell phone and is connected to communication between the communication equipment of PSTN 110.For example, cell phone 102a, 102b can with landline telephone that is connected to PSTN 110 or server communication.
Wireless RF link 106 is hanged down the communication link of data transmission rate for the typical case who is applicable to voice communication.Many legacy network original design in the PSTN110 also are only to be used for voice communication.Therefore, these legacy systems are limited by the low bandwidth communication link equally.Legacy cellular communication network 100 can use speech coding technology to realize low transmission rate on narrow band link.Speech coding technology is a voice compression algorithm.Voice compression algorithm is designed to provide the voice signal of best quality under system complexity and signal delay restraint condition.Speech coding system can be by using encoder-decoder that transmission and received speech signal on RF link 106 are realized in traditional cellular communications networks 100.
Represent that with the low bit rate digital signal analog voice signal can cause the distortion of primary speech signal.Powerful coding techniques as linear predictive coding (LPC), can shield distortion so that the voice signal of the high compression with high-quality and low bit rate to be provided.These coding techniquess can be issued to high-quality audio signals in the low bit rate situation by redundancy and the human auditory properties of use that uses primary speech signal.
A lot of speech coding systems are by supposing that original input is that pure voice are to reach high compression.Also promptly, most encoders use the voice tailor-made algorithms to all input signals codings, and according to described algorithm decoding, therefore, if on the link that uses described coded system transmission signals, the quality of signals of other non-voice will be affected.In the actual conditions, the input signal of input coding device can comprise background sound or other noise, causes the signal of corresponding decoder regeneration to have a large amount of distortions.The input signal of input coding device also can be a music signal.It is fair all very poor that music signal presents after by the encoder encodes that is used for speech coding.This makes the reproduction of the music that cell phone receives have very poor quality even horrible.
Perhaps, the most voice activity detectors (VAD) in the encoder are encoded music as noise, thereby cause the interior corresponding decoder of cell phone to export low-quality signal.Decoder in the cell phone generally according to coding techniques blindly to all signal decodings, if make the poor quality of input signal, cellular user is merely able to listen to low-quality signal input signal without any selection.
Fig. 2 is the schematic diagram of traditional cellular phone 200.Traditional cellular phone 200 shows the possible configuration of cell phone 102a, 102b among Fig. 1.Traditional cellular phone 200 provides the two-way wireless communication with base station (for example, base station 104a, the 104b among Fig. 1).Traditional cellular phone 200 comprises receive channel and the transmitting channel that is used for two-way communication.The reception of traditional cellular phone 200 and transmitting channel, and the basic operation of traditional cellular phone will be described below.
The transmitting channel of traditional cellular phone 200 comprises microphone 202.Microphone 202 is converted to electronic signal with sound.The simulation output of microphone 202 is amplified by amplifier 204.The simulation output of amplifier 204 is converted to digital signal by analog to digital converter (ADC) 206.The digital signal that ADC 206 produces is passed to encoder 208.Encoder 208 is carried out speech coding algorithm with the signal with digital signal boil down to low data rate.Described low data rate voice signal is by modulator 210 modulation.Digital to analog converter (DAC) 212 is converted to analog signal to be used for wireless transmission with the numeral output of modulator.The output signal that DAC 212 provides is base band or intermediate-freuqncy signal normally.This output signal is appropriate RF bandwidth by frequency up converters 214 frequency up-converted.Band pass filter 216 is used for filtering is carried out in the output of frequency up converters 214.At last, RF amplifier 218 is used to amplify by transmitting that traditional cellular phone 200 generates and handles.
Be passed to duplexer 220 by traditional cellular phone 200 transmitting of generation.Duplexer 220 switches traditional cellular phone 200 between receiver and reflector operation.In the emission process, duplexer 220 passes to antenna 222 with the output signal of RF amplifier 218, to carry out wireless transmission.In the receiving course, the signal that duplexer 220 receives antenna 222 passes to the receive channel of traditional cellular phone 200.
The receive channel of traditional cellular phone 200 comprises low noise amplifier (LNA) 224, is used to amplify the RF signal that receives from antenna 222.The RF output signal of LNA 224 is base band or intermediate-freuqncy signal by down-converter 226 frequency down-converts, and subsequently by low pass filter (LPF) 228 filtering.The output of LPF 228 is amplified by variable gain amplifier (VGA) 230.The simulation output of VGA 230 is converted to digital signal by ADC 232.Demodulator 234 demodulation are passed through in the numeral output of ADC 232, and are passed to conventional decoder 236.Conventional decoder 236 is transmitted the digital signal of decompression to DAC 238.The analog representation of the digital signal of the decompression that DAC generation conventional decoder 236 provides.The analog output signal that DAC 238 produces is passed to amplifier 240, and drives loudspeaker 242.Loudspeaker 242 conversions are sound from the analog electronic signal of amplifier 240.
As shown in Figure 2, controller 244 is connected to the reception and the send channel of traditional cellular phone 200.The operation of the vitals of the traditional cellular phone 200 that includes display and keyboard 246 is managed and controlled to controller 244.The memory 248 of traditional cellular phone 200 is also managed and controlled to controller 244.Controller 244 can be connected to the reception of traditional cellular phone 200 and a plurality of parts of send channel.
Traditional cellular phone 200 can with various communication apparatus communications, comprise another cell phone, landline telephone or remote server.Communication between traditional cellular phone 200 and the remote equipment realizes by the base station.Typically, (for example, the RF link 106 among Fig. 1) carried out in the communication between traditional cellular phone 200 and the base station on the arrowband Radio Link.Therefore, the code signal of the relatively low data transfer rate of base station exchange of traditional cellular phone 200 and correspondence.The code signal that traditional cellular phone 200 receives can transmit the equipment that signal to base station is used to be sent to traditional cellular phone 200 by base station and/or any other and encode.
Traditional cellular phone 200 mainly is set to send and received speech signal.After the effective call of equipment room was set up, voice signal exchanged between traditional cellular phone 200 and remote equipment.The signal that traditional cellular phone 200 receives in the effective call process uses the voice compression technique coding.Therefore, all use the voice compression technique coding from voice in the signal of remote equipment and non-speech audio part.
Voice signal comprises voice or the dialogue cycle between traditional cellular phone 200 and the remote device user.Voice signal also comprises the pause period in the quiet or dialogue between the user of the user of traditional cellular phone 200 and remote equipment.Non-speech audio is included in music or the mute periods that transfers to traditional cellular phone 200 in the effective call process.For example, non-speech audio is included in remote device user and allows traditional cellular phone 200 users wait to bide one's time the music that transfers to traditional cellular phone 200 or quiet.Non-speech audio does not comprise in effective calling procedure because of disturbing or that decay causes is quiet, noise or distortion.Non-speech audio does not comprise produce in normal call foundation or the disconnection termination process quiet, noise or distortion yet.In addition, non-speech audio does not comprise produce in the exemplary dialog process quiet, noise or distortion (for example, in the dialog procedure of short duration peace and quiet).
The encoded voice signal of communication that traditional cellular phone 200 receives is handled by conventional decoder 236.The code signal that conventional decoder 236 decodings receive also produces decoded signal.Decoded signal is passed to loudspeaker 242 subsequently.Conventional decoder 236 before transmission according to decode the blindly signal of all receptions of coding techniques.In addition, conventional decoder 236 can not be distinguished voice signal and non-speech audio from decoded signal.Therefore, the non-speech audio in the code signal of reception is decoded by conventional decoder 236, and exports by loudspeaker 242 as audio signal.Therefore, coding is holded music or is waited for that quiet encoder for noise or voice transmits the user of low-quality signal to traditional cellular phone 200.Therefore, no matter when non-speech audio (for example, wait for quiet or hold music) is transferred to traditional cellular phone 200, and the user of traditional cellular phone 200 must receive low-quality signal.
When remote equipment will place wait state with the calling of traditional cellular phone 200, transmission of music was to traditional cellular phone 200 usually.Bide one's time waiting, the service of holding music provides low-quality music to remote equipment, is used for coding and transfers to traditional cellular phone 200.Described music is normally undesired, and if coding quality very poor be insufferable.Perhaps, bide one's time, do not transmit any signal (for example, quiet) to traditional cellular phone 200 when remote equipment will place with the calling of traditional cellular phone 200 etc.
Can not detect under the situation of non-speech audio, the conventional detector 236 of traditional cellular phone 200 can not be distinguished the difference between encoding speech signal and coding non-speech audio or decodeing speech signal and the decoding non-speech audio.In addition, under the situation that can not detect non-speech audio, traditional cellular phone 200 can not provide the user to select the mechanism of another input in the non-speech audio receiving course.Because non-speech audio generally transmits a little information, and be useless, thereby expectation can provide another or second input during non-speech audio to the user of traditional cellular phone 200.For example, most users do not want to hear and hold music.In addition, if in the non-speech audio receiving course, it is insufferable that the user of traditional cell phone 200 can not select another input signal.Therefore, need a kind ofly can to detect non-speech audio, and can be with the communication equipment of at user option another or the second input replacement or replacement non-speech audio.
Fig. 3 is that the present invention can detect non-speech audio in the received signal and can use at user option another to import the schematic diagram of the cell phone 300 of alternative non-speech audio.The detectability of cell phone 300 of the present invention makes cell phone 300 can distinguish voice signal and non-speech audio.Specifically, detectability of the present invention makes cell phone 300 can detect holding music and wait for mute periods in the received speech signal.In addition, the present invention can realize that the non-voice of user in the voice signal that receives of cell phone 300 carries out with second input source in the cycle alternately.By this way, transmitting the input that the non-speech audio of a little information can use the user to select by low-quality signal substitutes.Generally speaking, the time that the user of cell phone 300 listens to low-quality signal is minimized or eliminates, to improve user's service efficiency and Experience Degree.
As shown in Figure 3, cell phone 300 comprises decoder 302.Decoder 302 is set to receive voice communication signals from remote equipment by base station (for example, the base station 104 of Fig. 1).The voice communication signals that cell phone 300 receives is represented the primary input of cell phone 300.Decoder 302 comprises detector 304.Non-speech audio in the voice communication signals that detector 304 detection cell phones 300 receive.Specifically, detector 304 can be configured to detect the interior non-speech audio of encoding speech signal that decoder 302 receives.Perhaps, detector 304 can be set to detect the interior non-speech audio of decodeing speech signal that decoder 302 generates.In all cases, detector 304 can detect holding music or wait for mute periods in the digital input signals.
Cell phone 300 further comprises controller/processor 306.Controller 306 managing cellular phones 300.Controller 306 as shown in the figure is connected to decoder 302 and encoder 208, and can be connected to the vitals of any amount of the reception of cell phone 300 and transmission path.Controller 306 operation display and keyboard 308, and the memory 310 of management and control cell phone 300.Controller 306 can be carried out the software application that is stored in the memory 310.

Controller 306 is connected to tuner/receiver 316.Tuner 316 is connected to antenna 318.Tuner 316 can be a TV tuner, receives the terrestrial broadcast television signal by antenna 318.Controller 306 can be managed the video image that receives from TV signal, and transmits it and watch to display 308.Perhaps, tuner 316 can be AM or FM receiver.The AM or the FM signal that receive can manage by controller 306, and offer the user.
As shown in Figure 3, controller 306 is connected to data collector 320.Data collector 320 is connected to antenna 322.Data collector 320 transmits and receives data by Radio Link.Data collector 320 can be super band data transceiver or high band wide data transceiver, for example, and bluetooth or IEEE 802 (for example, 802.11x, 802.15 or 802.16) wireless receiver.Data collector 320 can be set up being connected of cell phone 300 and wireless lan (wlan).Controller 306 can be set to the data link of supporting that data collector 320 provides.
Music player 312, tuner 316 and data collector 320 can be counted as secondary input source, because they have the feature of replenishing or replacing as the main speech communication function of cell phone 300.The feature of music player 312, tuner 316 and data collector 320 is mainly used in cell phone and does not carry out in the audio call situation with remote equipment.Unlike the prior art be that the non-voice that the present invention can make time input call out at efficient voice used in the cycle.Specifically, controller 306 can offer the user at the decodeing speech signal of self-demarking code in future device 302 and signal, feature or the output of the secondary input source in the cell phone 300 offered between the user and switch.For example, in detecting the process of non-speech audio, controller 306 can use switch 324 to be passed to the decodeing speech signal of loudspeaker 242 with interruption or time-out.In addition, in the cycle, controller 306 can use switch 324 to provide from the audio frequency of a secondary input source (for example, music player 312 or tuner 316) and export at non-voice.
The further feature of the present invention and following several spot correlations will be explained hereinafter: (a) detection of non-speech audio, (b) inferior input provide and (c) user strengthen feature.The cell phone 300 that aforementioned and following description relates to is a possibility embodiment of the present invention.Yet, it should be noted that to the invention is not restricted to employed this embodiment.The present invention is applicable to anyly have media decoder and have main input source and can visit the communication equipment or the system of one or more secondary input sources.For example, the present invention can be applicable to personal digital assistant (PDA), numeral or simulation landline telephone or PBX (PBX) phone and/or system.In addition, the present invention can be implemented in the wireless e-mail devices that comprises wireless phone service.In fact, secondary input source is used in the non-speech audio process and checks e-mails.
