Fig. 2 is the flow chart according to realization CS of the present invention territory voice service.
Embodiment
Below with reference to accompanying drawing, describe the specific embodiment of the present invention in detail.
The stream format definition that the present invention uploads sending voice in general ExpressCard interface or USB interface, support radio access module and PC or gateway kind equipment to upload sending voice data flow and control flows at general ExpressCard interface or USB interface, can be implemented under the GSM/GPRS/EDGE/WCDMA/HSDPA/HSUPA network, PC or gateway kind equipment are supported the basic talk business in CS territory and the function of speech supplementary service.
Radio access module is seen and can be comprised from hardware point of view: the radio frequency submodule, be used to receive and dispatch radiofrequency signal, and the radiofrequency signal that receives is sent to the base band submodule, for its processing; And the base band submodule, be used for up and/or downlink radio-frequency signal are carried out following processing: modulation/downlink space interface signal, channel coding/decoding, encrypt/decrypt, audio coding decoding, coding and decoding video, analog/digital conversion and digital-to-analog conversion.Comprise the power management submodule in addition, be used for the management start, detect dynamic electric voltage and be system's power supply.Radio access module externally provides the quick card or the USB interface of standard, and defer to " Universal SerialBus Class Definitions for Communication Devices " standard, realize as a standard CD C (communication device class, communication apparatus class) equipment.
When radio access module provides the pcm audio interface of standard, speech can transmit by pcm interface, but PC and gateway kind equipment are not supported this interface usually, maybe need expansion to support, therefore need be defined in the mode that quick card or USB interface are uploaded sending voice.Transmission (Isochronous) when the voice load mode of USB interface coideal is grade, Deng time transmission with fixing transmission rate, continuously between USB master controller and USB device, transmit data, when the transmission data make a mistake, USB does not handle these mistakes, but continues to transmit new data." Universal Serial Bus Specification " agreement 1.1 regulation, when adopting when waiting transmission means, maximum 1023 bytes of transmission that allow can define bigger stream format for this reason.The sampling rate of voice is 8KHz, adopting precision generally is 16bit, is 8bit after process A-Law or μ-Law compression, so the PCM of standard (Pulse Code Modulation, pulse code modulation) stream rate is 64Kbps, promptly transmits 160 bytes in every 20ms.
For this reason, the predefine frame format is the frame of 20ms, and is as follows:
| Sign 01111110 | Control 8bit | Data 1280bit | CRC 16bit | Sign 01111110 |
This 20ms frame comprises: banner word 01111110, control field 8bit, data field 1280bit, CRC check 16bit and banner word 01111110 promptly are similar to the structure of HDLC frame.Wherein control field is used for the form expansion, can deposit information such as control and sign, as the voice compression format that adopts, or Session ID etc., because the real-time of speech data is higher than correctness, so the CRC check field can.Because synchronous transmission is the transmission means towards bit, therefore do not need to define and distinguish each byte of transmission.
Under the situation that pipeline can be used when having etc., adopt predefine frame format transmitting voice information.Pipeline when not waiting (Isochronous Pipe) but the time spent can only adopt other transmission means.As batch pipeline (Bulk Pipe) but the time spent can adopt batch transmission (Bulk) mode, as interrupt pipe (Interrupt Pipe) but the time spent can adopt transmission (Interrupt) mode of interrupting.Owing to adopt when criticizing transmission means, maximum 64 bytes of transmission that allow adopt the interruption transmission means when full speed, the maximum permission transmitted 64 bytes, and when low speed, maximum only allows to transmit 8 bytes, need to define less stream format, the byte frame format for this reason.
The byte frame format is as follows:
| Initial 0 | Data 8bit | Parity check 1bit | Stop 1bit |
Owing to adopt asynchronous transmission mechanism, need define and distinguish each byte of transmission, therefore each byte frame is made of 1bit start bit, 8bit data bit, 1bit parity check bit and 1bit position of rest, promptly be similar to UART (universal asynchronism receivertransmitter, UART Universal Asynchronous Receiver Transmitter) structure of frame, because the real-time of speech data is higher than correctness, so parity check bit can.
The control flows of voice realizes that by AT (attention) command interface the AT command interface can adopt the data class interface (Data Class Interface) in the CDC standard, and detail is not at the row of this paper discussion.The AT command interface can be supported the AT Command Set of standard or expansion.
The present invention combines the various transmission meanss of quick card or USB interface and the characteristic of speech business, defined corresponding stream format, specifically introduced a kind of stream format of byte frame that adopts here and on ExpressCard interface or USB interface, realized the mode that voice transmit.
