[0002] The vehicle's emergency call (eCALL) is a vehicle accident emergency call system that uses mobile communications and satellite positioning functions to establish a telephone connection with the unified number of the nearest public safety answering point (PSAP) after a traffic accident. In addition to voice calls, the vehicle-mounted eCALL system also reports information such as the accident location and vehicle based on the minimum set of data (MSD). The reliable transmission of MSD is crucial to the vehicle-mounted eCALL system. Summary of the invention

[0003] The embodiments of the present application provide a vehicle emergency call method, device, equipment, vehicle and storage medium, which are introduced below from the following aspects.

[0004] In a first aspect, a vehicle emergency call method is provided, the method comprising: in response to a first preset event occurring, simultaneously sending a first minimum data set to a preset call center based on a first communication network and a second communication network.

[0005] In some implementations, in response to the occurrence of a second preset event, a second minimum data set is sent to a preset call center based on the first communication network or the second communication network, and the second minimum data set is sent later than the first minimum data set.

[0006] In some implementations, if the communication quality of the first communication network meets the first preset condition, a second minimum data set is sent to the preset call center based on the first communication network; if the communication quality of the first communication network does not meet the first preset condition, a second minimum data set is sent to the preset call center based on the second communication network.

[0007] In some implementations, communication quality is determined based on signal strength and / or signal transmission delay.

[0008] In some implementations, the target communication network for transmitting the second minimum data set is the same as the communication network corresponding to the received first message, and the first message is sent based on a preset call center.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: 5G system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided by the present application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

[0024] eCALL is a vehicle accident emergency call system that uses mobile communications and satellite positioning functions to establish a telephone connection with the unified number of the nearest rescue center after a traffic accident occurs. In addition to voice calls, the on-board eCALL system also reports the accident location and vehicle information. The basic concept of eCALL is to shorten emergency response time and reduce casualties and other accidents. Since the 1990s, cars have been equipped with 2G, 3G and 4G-based mobile communication equipment and eCALL on-board systems. When a vehicle is involved in an accident, the eCALL on-board system can automatically trigger an alarm or the occupants can choose to manually alarm. While establishing a voice call, the vehicle's location, direction of travel, frame number and vehicle model, number of occupants and other information are sent to the rescue center in the form of MSD, allowing the rescue center to quickly locate the accident vehicle and organize rescue. The following is combined with Figure 1 , introduce the eCALL system structure and workflow in related technologies.

[0025] like Figure 1 As shown in the figure, the eCALL system unit usually consists of the in-vehicle system (IVS), the ground mobile network and the public safety response point (PSAP). When an accident occurs, there are two ways to trigger eCALL: one is automatic triggering when the vehicle collides and the airbag pops out; the other is manual triggering, which is triggered by the eCALL button in the car or voice call triggering.

[0026] IVS includes sensors that detect that the SOS button is automatically or manually triggered, and an emergency call is issued. Mobile network operators (MNOs) support cellular networks with circuit domain voice services. They can identify eCALL calls through the "eCALL flag" carried in the emergency call establishment message and route the call to the most appropriate rescue platform. PSAP is a node (rescue platform) dedicated to processing eCALL. PSAP is connected to IVS through an in-band modem to receive MSD data related to the accident.

[0027] When the vehicle is started, the eCALL on-board system is powered on and initialized, and IVS completes network registration. After an accident occurs, eCALL will be automatically triggered to initiate an emergency call. The operator network identifies the "eCALL flag" carried in the call establishment message initiated by the terminal as an eCALL type emergency call. The mobile network routes this call to the PSAP corresponding to eCALL and establishes a connection between IVS and PSAP. Subsequently, IVS triggers the eCALL MSD transmission. The relevant technology uses an in-band modem to transmit MSD, that is, the MSD is time-division multiplexed and modulated to a digital voice channel using in-band modulation technology, and then transmitted to the PSAP through a 2G / 3G voice channel. After the MSD message is transmitted or the transmission fails and times out, it automatically switches to call mode, and the PSAP rescuer can establish a voice call with the caller. The following is a detailed introduction to the important technical steps involved in the eCALL process.

[0028] Step 1: eCALL call establishment process

[0029] The call establishment process of eCALL consists of two parts, one is the general process of the mobile network, and the other is the call control process of the mobile network. The general process of the mobile network includes authentication, connection management after location update, and security encryption. After the general process of the mobile network is completed, the mobile call control process is established. The mobile call control process is used to establish the voice channel between the IVS and the PSAP. After the voice channel is established, the interaction and transmission of the MSD will begin.

[0030] Step 2: eCALL MSD transmission

[0031] In an eCALL emergency call, for operators, what is transmitted in the voice channel is "voice". Based on the in-band modulation and demodulation technology, MSD and voice can be transmitted in the voice channel. The following is an introduction to the in-band modulation and demodulation technology.

[0032] The in-band modem of eCALL is a full-duplex modem pair consisting of the transmitter and receiver of IVS and PSAP. The structure of IVS includes a radio modem and a speech codec. After the voice channel is established, the transmission system is connected to the radio modem of IVS and the speech codec is connected in series. The speech codec selects whether to connect to the data modem of IVS or the microphone for conversation based on the switch. When the voice channel processes these two inputs, the IVS controls whether the content transmitted in the voice channel is MSD or voice. On the PSAP side, there is also a switch to select the data modem or microphone to receive MSD or talk with the staff. Whether to transmit MSD or voice is realized by software-controlled switches, and the default initial connection is data transmission mode. Under normal circumstances, an eCALL call is automatically or manually initiated after an accident occurs. The speech codec of IVS connects to the data modem to trigger the MSD transmission. After the transmission is completed, the speech codec connects to the microphone to convert to a voice call; during the call, if the PSAP requires additional MSD, it can notify the IVS to transmit the latest MSD at any time through instructions, and it can be converted to a voice call again after the transmission is completed.

[0033] Step 3: Coordination of MSD transmission and voice

[0034] There are data modems and microphones in the IVS and PSAP systems. The switching between the data modem and the microphone is controlled by software and requires coordination. After the voice channel is established, the modem in the IVS transmits MSD data to the PSAP. After the PSAP successfully receives the MSD, the PSAP sends the AL-ACK application layer confirmation instruction to the IVS through the in-band modem. If the value of AL-ACK is "positive", it will be transferred to an artificial voice call; if the value of AL-ACK is "clear-down", the conversation will be ended directly by hanging up. In the previous step, if the value of AL-ACK is "positive", it will be transferred to an artificial voice call, and the passengers in the car will communicate with the PSAP staff about the accident status and rescue matters. Finally, the call ends and the call is released. During the voice call, the modem of the IVS continues to monitor the channel signal, and the PSAP staff can instruct the IVS to send the latest MSD at any time as needed.

[0035] Ordinary eCALL is a technology developed for 2 / 3G circuit domain emergency calls. As 4G LTE networks are widely deployed around the world, operators may gradually phase out circuit domain networks in the future. eCALL also needs to keep pace with the times and upgrade to the next generation of eCALL based on IMS emergency calls, namely NG-eCALL.

[0036] Compared with ordinary eCALL, NG-eCALL can effectively support the concurrency of voice and packet data between IVS and the same PSAP. By utilizing the ability of IMS to support emergency call services, NG-eCALL can greatly shorten the call establishment delay; and supports the concurrency of VoLTE voice and data, and can obtain static and dynamic images and audio information on the scene during remote rescue. In the system architecture of NG-eCALL, the main network elements include cellular networks that support IMS-based emergency calls, IVS that support NG-eCALL functions, and PSAPs that support NG-eCALL functions.

[0037] The in-vehicle system IVS initiates an emergency call through the network; the visited network establishes a route to the PSAP through the IMS, which includes the SIP / IP signaling route and the media route. The media route transmits voice information, and the MSD information is sent to the PSAP through the SIP signaling message. The signaling route and the media route are relatively independent, and the voice media route is not interrupted or affected by the MSD transmission.

[0038] The above introduces the system structure and workflow of eCALL. According to the above content, the MSD carries a variety of accident vehicle information, which is very important for emergency rescue, and the successful transmission of the MSD is also a prerequisite for voice calls. Therefore, the transmission of MSD is crucial to the entire eCALL system. In the related art, the eCALL system transmits MSD based on a single ground communication network (such as a cellular network). If the vehicle accident is in a weak ground network or a scenario with no ground network, it will not be possible to ensure that the MSD can be successfully sent to the PSAP. In an embodiment of the present application, the MSD is sent to the PSAP simultaneously based on two communication networks (such as a ground communication network and a satellite communication network) to achieve backup transmission of the MSD, thereby helping to improve the reliability of MSD transmission.

[0039] Combined with the following Figure 2 , the vehicle emergency call method provided in the embodiment of the present application is introduced in detail.

[0040] like Figure 2 As shown, in step S210, in response to the occurrence of a first preset event, a first minimum data set is sent to a preset call center based on the first communication network and the second communication network at the same time.

[0041] Before executing step S210, Figure 2 The method shown can also first make an emergency call to establish a connection channel between the vehicle and the preset call center, for example, see Figure 1 The process of establishing a voice channel between IVS and PSAP.

[0042] The minimum data set (MSD) may include a variety of information. For example, the MSD may include a variety of information related to the accident vehicle, such as the triggering reason (automatic triggering or manual triggering), the type of emergency call (real emergency call or test emergency call), the vehicle type (such as a car, a bus), the vehicle's unique identification number, the fuel type, the timestamp, the vehicle's location information (i.e., the vehicle's latitude and longitude information), the accuracy of the location information (such as 10m, 5m), the vehicle's driving direction, the number of passengers, etc.

[0043] The embodiment of the present application does not specifically limit the first preset event, as long as it can cause the vehicle to send the MSD. Two first preset events are introduced below for easy understanding.

[0044] The first preset event may be an emergency call initiated by the vehicle. For example, the first preset event may be an automatically triggered or manually triggered emergency call. Manual triggering may be, for example, triggering an eCALL button (such as an SOS button) in the vehicle or triggering an emergency call by voice call. Automatic triggering may be, for example, automatically triggering an emergency call when a collision occurs in the vehicle and the airbag is deployed.

[0045] The first preset event may also be related to channel establishment or signal transmission. For example, the first preset event may be a request signal from a preset call center requesting to send an MSD, and based on the request information, the vehicle sends the MSD to the preset call center. For another example, the first preset event may also be the completion of the establishment of a speech channel between the vehicle and the preset call center, and based on the completion of the speech channel establishment, the vehicle sends the MSD to the preset call center.

[0046] The preset call center mentioned above may also have other names. For example, the preset call center may be called a public safety answering point (PSAP), a rescue center, a rescue platform, a public safety response point center, and the like.

[0047] The MSD carries a variety of accident vehicle information, which is very important for emergency rescue, and the successful transmission of the MSD is also a prerequisite for voice calls. Therefore, the transmission of the MSD is crucial to the entire eCALL system. In the related art, the eCALL system transmits the MSD based on a single ground communication network (such as a cellular network). If the vehicle accident is in a scenario with a weak ground network or no ground network, it cannot be ensured that the MSD can be successfully sent to the preset call center. In an embodiment of the present application, the MSD is sent to the preset call center simultaneously based on two communication networks (i.e., the first communication network and the second communication network) to achieve backup transmission of the MSD, thereby helping to improve the reliability of MSD transmission.

[0048] The embodiment of the present application can select any two communication networks from a variety of communication networks to simultaneously transmit the MSD. The various communication networks here may include terrestrial communication networks, such as 2G mobile communication networks, 3G mobile communication networks, 4G mobile communication networks, 5G mobile communication networks, and future mobile communication networks in cellular networks. The various communication networks may also include non-terrestrial communication networks, such as the Tiantong satellite communication network, the Iridium communication network, the Maritime satellite communication network, the Globalstar communication network, and future satellite communication networks in satellite communication networks.

[0049] In some implementations, the first communication network is a terrestrial communication network, and / or the second communication network is a satellite communication network. For example, the first communication network may be a cellular network, and the second communication network may be a Tiantong satellite communication network. Satellite communication networks have a wider coverage and higher reliability than terrestrial communication networks. In scenarios with weak terrestrial networks or no terrestrial networks, transmitting MSDs based on satellite communication networks can further improve the reliability of MSD transmission.

[0050] In the introduction Figure 1 When talking about the eCALL system in 2G / 3G mobile communication networks, it is mentioned that in 2G / 3G mobile communication networks, an eCALL call is automatically or manually initiated after an accident occurs. The voice codec of IVS is connected to the data modem to trigger the MSD transmission. After the transmission is completed, the voice codec is connected to the microphone to switch to a voice call. During the call, if the PSAP requires additional MSD, it can notify the IVS to transmit the latest MSD at any time through instructions. After the transmission is completed, it can be switched to a voice call again. In other words, in some terrestrial communication networks, the transmission of MSD and the call occupy the same channel, which makes it impossible for the two to be carried out at the same time.

[0051] The satellite communication network used for mobile communication can provide satellite call service and data transmission service. The information in these two services is transmitted based on different network channels, wherein voice information is transmitted based on the call channel of the satellite communication network, and data information is transmitted based on the data channel of the satellite communication network. In the embodiment of the present application, by using the call channel and data channel of the satellite communication network to transmit MSD and make phone calls respectively, it is possible to achieve the transmission of MSD and the call at the same time, thereby helping to improve the efficiency of vehicle emergency calls. Figure 3 , taking the first communication network as a cellular network and the second communication network as the Tiantong satellite communication network as an example, a possible implementation method of the eCALL system of an embodiment of the present application is introduced.

[0052] like Figure 3 As shown in the figure, the eCALL system consists of four parts: the in-vehicle system (IVS), the cellular network (2G / 3G mobile communication network), the Tiantong satellite communication network and the public safety answering point (PSAP).

[0053] When a vehicle accident occurs and an emergency call is triggered, the operator network identifies it as an eCALL type emergency call through the "eCALL flag" carried in the call establishment message initiated by the terminal. The mobile communication network routes this call to the PSAP corresponding to the eCALL and establishes a connection between the IVS and the PSAP. Among them, a voice channel is established between the IVS and the PSAP based on the 2G / 3G mobile communication network, and a call channel and a data channel are established between the IVS and the PSAP based on the Tiantong satellite communication network. Subsequently, the IVS transmits the MSD to the PSAP through the voice channel and the data channel at the same time, and the call channel establishes a voice call between the PSAP and the IVS. In this way, the MSD is sent to the PSAP at the same time based on the two communication networks to achieve backup transmission of the MSD, thereby improving the reliability of the MSD transmission. In addition, while obtaining accident information, the PSAP staff can also keep in touch with the rescue personnel.

[0054] In some cases, the vehicle may need to send the MSD to the preset call center multiple times. For example, the staff of the preset call center instructs the vehicle to resend the latest MSD through request information as needed. In another example, the vehicle resends the latest MSD to the preset call center based on the default setting or the personnel in the vehicle actively. The default setting here can be, for example, a preset period of time, or it can also be when the data information in the MSD changes.

[0055] When the preset events mentioned above are triggered, the vehicle will send the MSD again. The specific method can refer to the method introduced in the previous article, that is, sending the MSD to the preset call center based on two communication networks at the same time to ensure the reliability of MSD transmission.

[0056] Alternatively, in some implementations, the MSD can be sent again to the preset call center based on the first communication network or the second communication network. That is to say, after a preset event occurs, the vehicle can send the MSD to the preset call center based on only one communication network. This approach takes into account that after the preset call center has received the MSD once, subsequent MSD transmissions can take economic issues into consideration more. The cost of communicating using one communication network is significantly lower than the cost of communicating using two communication networks, especially the communication costs of satellite communication networks are usually higher than those of ground networks. Therefore, when the vehicle sends the MSD again, sending the MSD to the preset call center based on one communication network helps to reduce communication costs.

[0057] There are multiple methods for selecting a communication network from two communication networks to transmit the MSD. For example, the MSD can be directly transmitted again based on a preset target communication network (the first communication network or the second communication network). Alternatively, the target communication network for transmitting the MSD again can be determined based on whether the communication quality of the communication network meets the preset conditions, which are described below.

[0058] The communication quality of the communication network can be represented by signal indicators. For example, signal indicators indicating communication quality may include: transmission rate, bit error rate, signal strength, signal quality, delay, jitter, and packet loss rate. The communication quality can be represented based on the above-mentioned single signal indicator or based on a combination of multiple signal indicators.

[0059] The preset conditions mentioned above may be whether the signal indicator meets a specific threshold, for example, whether the signal strength of the communication network is greater than a first threshold, or whether the signal delay time of the communication network is less than a second threshold, or whether the signal packet loss rate of the communication network is less than a third threshold.

[0060] In some cases, such as a scenario where both communication networks are terrestrial networks or satellite communication networks, the communication qualities of the two communication networks may be compared to determine a target communication network to which the MSD is to be retransmitted.

[0061] Taking the terrestrial communication network as an example, the first communication network and the second communication network are different types of cellular networks. If the signal strength of the first communication network is greater than the signal strength of the second communication network, the MSD is sent to the preset call center based on the first communication network; if the signal strength of the first communication network is less than the signal strength of the second communication network, the MSD is sent to the preset call center based on the second communication network.

[0062] Taking a satellite communication network as an example, the first communication network and the second communication network are different types of satellite mobile communication networks. If the signal delay of the first communication network is less than the signal delay of the second communication network, the MSD is sent again to the preset call center based on the first communication network; if the signal delay of the first communication network is greater than the signal delay of the second communication network, the MSD is sent again to the preset call center based on the second communication network.

[0063] In other cases, such as two communication networks, one of which is a terrestrial communication network and the other is a satellite communication network, the target communication network to which the MSD is retransmitted may be selected based on the communication quality of the one communication network.

[0064] In some implementations, if the communication quality of the first communication network meets the first preset condition, the MSD is sent again to the preset call center based on the first communication network; if the communication quality of the first communication network does not meet the first preset condition, the MSD is sent again to the preset call center based on the second communication network.

[0065] Take the ground communication network and the satellite communication network as an example, where the first communication network is a cellular network and the second communication network is a satellite mobile communication network. If the signal strength of the first communication network is greater than or equal to the first threshold, the MSD is sent again to the preset call center based on the first communication network; if the signal strength of the first communication network is less than the first threshold, the MSD is sent again to the preset call center based on the second communication network. When the signal strength of the cellular network meets the requirements, it is sufficient to send the MSD again based on the cellular network, which can not only successfully transmit the MSD to the preset call center, but also avoid the high cost of satellite communication. When the signal strength of the cellular network does not meet the requirements, the MSD is transmitted again based on the satellite mobile communication network to ensure the reliability of the transmission.

[0066] Alternatively, the first communication network is a satellite mobile communication network, and the second communication network is a cellular network. If the signal delay of the first communication network is less than or equal to the second threshold, the MSD is sent again to the preset call center based on the first communication network; if the signal delay of the first communication network is greater than the second threshold, the MSD is sent again to the preset call center based on the second communication network.

[0067] When the vehicle transmits the MSD again, it can also transmit directly based on the preset target communication network. The preset here can mean that when the MSD needs to be sent again, the first communication network or the second communication network is set by default to transmit the MSD. For example, when the vehicle needs to send the MSD again, the MSD can be transmitted based on the cellular network by default. Alternatively, the preset here can also be consistent with the data transmission method of the preset call center.

[0068] In some implementations, the target communication network for retransmitting the MSD is the same as the communication network corresponding to the first message received by the vehicle.

[0069] The first message is sent based on the preset call center. If the vehicle can receive the first message, it means that the communication quality of the communication network transmitting the message can meet the requirements. Therefore, the communication network corresponding to the first message can be directly used as the target communication network to transmit the MSD again to improve the transmission efficiency.

[0070] The embodiment of the present application does not limit the type of the first message. For example, the first message may be a confirmation message (ack) from the preset center confirming that the MSD has been received, or a request message requesting to send the MSD again, or a voice message in a voice call. Figure 3 , taking the first communication network as a cellular network and the second communication network as the Tiantong satellite communication network as an example, another possible implementation method of the eCALL system of the embodiment of the present application is introduced.

[0071] like Figure 3 As shown in the figure, the eCALL system consists of four parts: vehicle IVS, cellular network (2G / 3G mobile communication network), Tiantong satellite communication network and PSAP.

[0072] When a vehicle accident occurs and an emergency call is triggered, the operator network identifies the call as an eCALL type emergency call through the "eCALL flag" carried in the call establishment message initiated by the terminal. The communication network routes the call to the PSAP corresponding to the eCALL and establishes a connection between the IVS and the PSAP. A voice channel is established between the IVS and the PSAP based on the 2G / 3G mobile communication network, and a call channel and a data channel are established between the IVS and the PSAP based on the Tiantong satellite communication network. Subsequently, the IVS transmits the MSD to the PSAP through the voice channel and the data channel at the same time, and the call channel establishes a voice call between the PSAP and the IVS.

[0073] When the IVS of the vehicle is required to send the MSD again, the method of determining the target communication network may include the following two methods, for example:

[0074] (1) Detecting the signal strength of the 2G / 3G mobile communication network. If the signal strength of the 2G / 3G mobile communication network is greater than or equal to a first threshold, transmitting the MSD through a voice channel established based on the 2G / 3G mobile communication network; if the signal strength of the 2G / 3G mobile communication network is less than the first threshold, transmitting the MSD through a data channel established based on the Tiantong satellite communication network;

[0075] (2) Determine the transmission channel corresponding to the confirmation message (ack) received after the first MSD is sent. If the confirmation message is transmitted based on the voice channel established by the 2G / 3G mobile communication network, the MSD is transmitted based on the voice channel; if the confirmation message is transmitted based on the data channel established by the Tiantong satellite communication network, the MSD is transmitted based on the data channel.

[0076] Combination of the above Figures 1 to 3 , describes the method embodiment of the present application in detail, and the following is combined with Figures 4 to 6, describes the device embodiment of the present application in detail. It should be understood that the description of the method embodiment corresponds to the description of the device embodiment, so the parts not described in detail can refer to the previous method embodiment.

[0077] Figure 4 This is a schematic diagram of the structure of the vehicle emergency call device provided in the embodiment of the present application. Figure 4 As shown, the vehicle emergency call device 400 includes a communication module 410 .

[0078] The communication module 410 is configured to send a first minimum data set to a preset call center based on the first communication network and the second communication network simultaneously in response to the occurrence of a first preset event.

[0079] In some implementations, the communication module 410 is further used to send a second minimum data set to the preset call center based on the first communication network or the second communication network in response to a second preset event, and the sending time of the second minimum data set is later than the sending time of the first minimum data set.

[0080] In some implementations, the communication module 410 is also used to send the second minimum data set to the preset call center based on the first communication network if the communication quality of the first communication network meets the first preset condition; if the communication quality of the first communication network does not meet the first preset condition, send the second minimum data set to the preset call center based on the second communication network.

[0081] In some implementations, the communication quality is determined based on signal strength and / or signal transmission delay.

[0082] In some implementations, the target communication network for transmitting the second minimum data set is the same as the communication network corresponding to the received first message, and the first message is sent based on the preset call center.

[0083] In some implementations, the first communication network is a terrestrial communication network, and / or the second communication network is a satellite communication network.
