However, if the vehicle-mounted terminal is in an emergency call in-band (eCall in-band) mode, the START MSG cannot be successfully received, and a great potential safety hazard exists.
In order to monitor voice data in real time and improve reliability and integrity of data transmission, the embodiment of the application provides a data processing method. In order to better understand the data processing method provided in the embodiments of the present application, the data processing method is described in detail below.
Referring to fig. 2, fig. 2 is a flowchart of a data processing method provided in the embodiment of the present application, where the data processing method includes steps 201 to 202. The main body for executing the method shown in fig. 2 may be a terminal device, or the main body may be a chip in the terminal device. The method shown in fig. 2 is executed by taking a terminal device as an example. Wherein:
201. when the terminal equipment is in a voice channel, the terminal equipment detects whether the voice data in the voice channel has IVS data.
In the embodiment of the present application, in an emergency call in-band (eCall in-band) mode, during a normal voice call, voice data in a voice path needs to be monitored in real time. Wherein, under the condition that the terminal equipment is in an eCall in-band mode, the terminal equipment has the capability of sending data through a voice path. The voice data in the voice path may include IVS data, which may include, for example, a Start Message (Start MSG) sent by the PSAP, tone signal data, IVS synchronization data, and so forth. If it is detected that the voice data includes the IVS data, the current path needs to be switched subsequently to ensure that the voice data can be correctly processed. When the terminal equipment detects the voice data in the voice channel, the adopted detection module cannot damage the original voice data, and the influence on the normal conversation process is avoided. Based on the mode, the voice data can be monitored in real time, and the reliability and the integrity of data transmission are improved.
It should be noted that the process of acquiring the voice data by the terminal device is as follows: the terminal device receives the data of the radio frequency antenna port, starts the wireless communication module to perform channel decoding on the data of the radio frequency antenna port, outputs a decoding result to an audio Adaptive Multi-Rate (AMR) for voice decoding, and takes Pulse Code Modulation (PCM) data output by the AMR decoding as the voice data received by the terminal device. When the terminal equipment is in a voice channel, the terminal equipment starts a detection module to detect voice data in the voice channel. Illustratively, the detection module includes a single tone signal detection module and a synchronization signal detection module.
In one possible implementation, when the terminal device is in the IVS data path, the terminal device processes the voice data in the IVS data path. For a terminal device in the IVS data path, the IVS data path may be directly adopted for processing.
202. If the voice data has IVS data, the terminal equipment switches the voice channel to an IVS data channel to process the voice data.
In the embodiment of the application, the terminal device monitors the voice data in the voice channel, determines whether the voice data contains the IVS data, and if the voice data contains the IVS data, the voice channel needs to be switched to the IVS data channel to process the voice data. Based on the mode, the voice data can be correctly processed, and the reliability and the integrity of data transmission can be improved.
Specifically, when an emergency (e.g. collision) occurs in a car, information such as an emergency state, a current location of a terminal device, and the like, i.e. MSD data, is manually or automatically triggered and transmitted to a network device (PSAP) through a cellular network. After receiving the MSD data sent by the terminal device, the network device sends START MSG to the terminal device to obtain some more specific data related to the traffic accident. When the terminal equipment detects that the IVS data exists in the voice data, the voice channel is switched to the IVS data channel to process the voice data, and the missing of the START MSG message issued by the network equipment is avoided. After the terminal equipment successfully receives the START MSG sent by the network equipment, eCall MSD information can be sent to the network equipment at any time during voice communication, and the eCall MSD information comprises more specific data related to traffic accidents, so that the completeness of rescue data is guaranteed, the rescue efficiency is improved, and the rescue time is shortened.
In the method described in fig. 2, when the terminal device is in the voice channel, the terminal device monitors in real time whether the voice data in the voice channel includes the IVS data, and if the voice data includes the IVS data, the current voice channel needs to be switched to the IVS data channel to process the voice data. Therefore, based on the method described in fig. 2, the voice data can be monitored in real time, which is beneficial to improving the reliability and integrity of data transmission.
Referring to fig. 3, fig. 3 is a flowchart of another data processing method according to an embodiment of the present disclosure. The data processing method includes steps 301 to 306. Step 301 to step 305 are a specific implementation manner of step 201. The main body for executing the method shown in fig. 3 may be a terminal device, or the main body may be a chip in the terminal device. The method execution subject shown in fig. 3 takes a terminal device as an example. Wherein:
301. when the terminal equipment is in a voice channel, the terminal equipment performs single tone signal detection on voice data in the voice channel.
In the embodiment of the present application, the monophonic signal detection is used to determine whether the speech data has monophonic signal data. It should be noted that the single-tone signal is also called a single-frequency signal, that is, a signal with a constant frequency is only used, and the signal may be a sine signal or a cosine signal. Because the IVS data includes single tone signal data, if there is single tone signal data in the voice channel, it indicates that there is IVS data in the voice channel, and then it is necessary to switch the current channel to ensure that the voice data can be processed correctly. Based on the mode, the voice data can be monitored in real time, and the reliability and the integrity of data transmission are improved.
In one possible implementation manner, the terminal device performs tone signal detection on the voice data in the voice path, including: the terminal equipment copies the voice data in the voice channel and stores the voice data as a voice data copy; the terminal equipment detects the tone signal of the voice data copy. The PCM data output by AMR decoding is used as the input data of the single tone signal detection module, so that in order to avoid the damage of the original data by the single tone signal detection module, a storage space can be opened up to store a voice data copy, and then the voice data copy is processed.
302. The terminal device determines whether the tone signal detection is successful. If the tone signal detection is successful, step 306 is executed. If the tone signal detection fails, step 303 is executed.
303. The terminal equipment detects the synchronous signal of the voice data in the voice channel.
In the embodiment of the present application, the synchronization signal detection is used to detect whether the voice data has IVS synchronization data. Because the IVS data also comprises the IVS synchronous data, if the voice data in the voice channel has the IVS synchronous data, the voice data in the voice channel has the IVS data, and the current channel needs to be switched subsequently to ensure that the voice data can be processed correctly. It should be noted that the IVS synchronization signal can complete synchronization between the network device and the terminal device (IVS system). Based on the mode, the voice data can be monitored in real time, and the reliability and the integrity of data transmission are improved.
304. The terminal device determines whether the synchronization signal detection is successful. If the sync signal detection is successful, go to step 306. If the sync signal detection fails, step 305 is executed.
305. The terminal equipment determines that the voice data does not have IVS data, and processes the voice data in the voice channel.
In the embodiment of the application, the terminal device fails to detect both the tone signal and the synchronization signal of the voice data in the voice channel, which indicates that there is no IVS data in the voice channel, and the voice data is processed in the current voice channel without switching the channel for processing. Illustratively, the voice data may be output to an audio player for processing, and so forth.
306. And the terminal equipment determines that the voice data has IVS data, and switches the voice channel to an IVS data channel to process the voice data.
In the embodiment of the application, the terminal device adopts the single tone signal detection module and the synchronous signal detection module to detect the voice data in the voice channel, and when the voice data is determined to have the IVS data, the terminal device switches the current voice channel to the IVS data channel, so that the voice data can be ensured to be correctly processed, and the missing of the IVS data issued by the network device is avoided. Based on the mode, the voice data can be monitored in real time, and the reliability and the integrity of data transmission are improved.
In the method described in fig. 3, when the terminal device is in the voice channel, the terminal device monitors the voice data in the voice channel in real time through monophonic signal detection and synchronization signal detection, and if the voice data includes IVS data, it is necessary to switch the current voice channel to the IVS data channel to process the voice data. Therefore, based on the method described in fig. 3, the voice data can be monitored in real time, which is beneficial to improving the reliability and integrity of data transmission.
