Description

Technical Field

[0001] This application relates to the field of intelligent driving technology, and in particular to a method and apparatus for multi-device joint calling. Background Technology

[0002] In the event of a vehicle collision, to ensure timely assistance to occupants, users can make an emergency call via a terminal device. For example, based on the advanced mobile location (AML) integrated into the terminal device, when AML is enabled, the terminal device establishes a voice call with the emergency call platform. Simultaneously, the terminal device automatically collects location information and reports the location, phone number, or called number to the emergency call platform. The emergency call platform can then transmit this information to the emergency call platform, enabling the platform to initiate rescue operations based on the received data.

[0003] However, there are limitations to making emergency calls through terminal devices. For example, when the terminal device's battery is low, the information reporting process may be interrupted, preventing the rescue platform from obtaining accurate location information. Or, when the terminal device is damaged to a certain extent, it may not be able to support effective emergency calls, resulting in the inability to report location information to the rescue platform. Summary of the Invention

[0004] This application provides a multi-device joint calling method and apparatus, applied in the field of intelligent driving technology. The method includes: a first device establishing short-range communication with a second device; the first device obtaining relevant information about the second device based on the short-range communication; the first device sending the relevant information of the second device and the relevant information of the first device to a third device; and the first device receiving a paging from the third device. The paging is sent by the third device based on the relevant information of the second device and the relevant information of the first device. In this way, in cases where the second device has insufficient power or malfunctions, the second device can reliably transmit emergency information through the first device. The third device, by parsing the relevant information of the second device and the relevant information of the first device, can send a paging to the first device and obtain rescue-related information, thereby dispatching personnel to carry out rescue operations.

[0005] In a first aspect, embodiments of this application provide a multi-device joint calling method. The method includes: a first device establishing short-range communication with a second device; the first device obtaining relevant information about the second device based on the short-range communication; the first device sending the relevant information of the second device and the relevant information of the first device to a third device; and the first device receiving a paging message from the third device. The paging message is sent by the third device based on the relevant information of the second device and the relevant information of the first device. In this way, in cases where the second device has insufficient power or malfunctions, the second device can reliably transmit emergency information through the first device. The third device, by parsing the relevant information of the second device and the relevant information of the first device, can send a paging message to the first device and obtain rescue-related information, thereby dispatching personnel to carry out rescue operations.

[0006] In one possible implementation, the first device establishes short-range communication with the second device, including: the first device receiving a connection establishment request from the second device; the first device verifying the identity of the second device based on the connection establishment request and first subscription information, the first subscription information indicating that at least one assisted device is permitted to assist in calling a third device; and, if the second device's authentication is successful, the first device establishes short-range communication with the second device. In this way, the first device can obtain relevant information about the second device through this short-range communication.

[0007] In one possible implementation, the connection establishment request includes a request reason, and the first subscription information also includes conditions under which the first device allows the establishment of short-range communication. Based on the connection establishment request and the first subscription information, the first device verifies the identity of the second device, including: if the request reason and conditions match, and at least one assisted device includes the second device, the second device's authentication is successful. Thus, the first device can correctly establish short-range communication with the first device that sent the request reason, based on the received request reason.

[0008] In one possible implementation, the request reason includes at least one of the following: the second device detects a collision event, the second device detects a distress event, the second device has insufficient power, or the second device is the device being assisted.

[0009] In one possible implementation, the paging is for a voice call, and the method further includes: the first device automatically answers the call based on the paging.

[0010] In one possible implementation, the aforementioned call is answered hands-free. This allows users to report their surroundings via voice calls, thereby improving rescue efficiency.

[0011] In one possible implementation, before the first device establishes short-range communication with the second device, the method further includes: the first device receiving a short-range communication function activation instruction from a third device; and the first device activating its short-range communication function according to the short-range communication function activation instruction. Thus, even if the short-range communication function is not already activated, the first device can activate it according to the short-range communication function activation instruction.

[0012] In one possible implementation, the relevant information of the first device includes one or more of the following: the location information of the first device, timestamp information related to the first device, contact information of the first device, identification number of the first device, or trajectory information of the first device; or,

In this way, the third device can learn about the surrounding situation of the first device through paging, and can simultaneously implement emergency rescue based on the received information.

[0015] In one possible implementation, the third device sends a paging request message to the first device, including: if the third device receives no response when paging the second device, it sends a paging request to the first device. This allows the third device to understand the surrounding situation of the first device through the first device, improving rescue efficiency.

[0016] In one possible implementation, before the third device sends a paging request to the first device, the method further includes: the third device receiving a short-range communication request from the second device; the third device verifying the identity of the first device based on the short-range communication request and second subscription information, the second subscription information indicating at least one assisting device that is permitted to assist the second device in calling the third device; and, if the first device's authentication is successful, the third device sending a short-range communication function activation instruction to the first device. In this way, the third device can instruct the first device to activate the short-range communication function even if the first device has not activated it.

[0017] In one possible implementation, the third device verifies the identity of the first device based on the short-range communication request and subscription information, including: if the first device is an assisting device, the first device's authentication is successful. In this way, the third device can correctly send a short-range communication function activation instruction to the second device.

[0018] In one possible implementation, the relevant information of the first device includes one or more of the following: the location information of the first device, timestamp information related to the first device, contact information of the first device, identification number of the first device, or trajectory information of the first device; or,

[0019] The relevant information of the second device includes one or more of the following: the location information of the second device, the timestamp information associated with the second device, the contact information of the second device, the identification number of the second device, the trajectory information of the second device, or the reason why the second device is assisted in calling the third device.

[0023] In one possible implementation, before the second device sends a connection establishment request to the first device, the method further includes: the second device sending a short-range communication request to the third device.

[0068] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and purpose. For example, "first chip" and "second chip" are used only to distinguish different chips and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" do not necessarily imply that they are different.

[0069] It should be noted that, in the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0070] In this application embodiment, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0071] In the event of a vehicle collision, in order for the occupants to receive timely assistance, they need to initiate an emergency call. This emergency call will allow them to receive help from rescue personnel, thereby reducing property damage and minimizing casualties.

[0072] One possible implementation involves using a user's in-vehicle terminal device to make an emergency call. This terminal device's operating system integrates Advanced Mobile Location (AML) technology, a location-based emergency location technology. This AML technology can shorten the time required for the rescue platform to confirm the user's location, thereby reducing the arrival time of rescue personnel.

[0073] For example, Figure 1 This is a schematic diagram of an emergency call method in the prior art, such as... Figure 1As shown, when AML is enabled, when a user dials an emergency number via the public telecommunications network, the terminal device establishes a voice call with the alarm platform. Simultaneously, the terminal device's operating system automatically collects its location information and reports this information, including the phone number or called number, to the rescue platform. The rescue platform then sends this information to the alarm platform, enabling it to promptly dispatch rescue personnel. The emergency number can include 110 or 120, the alarm platform can include the 110 or 120 emergency platform, and the rescue platform can include a public safety answering point (PSAP).

[0074] Another possible implementation is through an in-vehicle emergency call (eCall) device. This eCall device can be pre-installed in the vehicle by the manufacturer or installed by the user.

[0075] For example, Figure 2 This is a schematic diagram of an emergency call method in the prior art, such as... Figure 2 As shown, when a vehicle is involved in a traffic accident such as a collision, the in-band eCall device can automatically initiate an in-band emergency call via the public telecommunications network, establishing a voice communication link between the vehicle and the alarm platform. This voice communication link enables voice communication between the vehicle and the alarm platform. Because the voice call synthesizes a minimum data set (MSD) including location information and the vehicle identification number (VIN), rescue personnel can use the MSD to promptly initiate rescue operations. The alarm platform can include the 110 (police) alarm platform or the 120 (ambulance) alarm platform, etc.

[0076] However, using a terminal device to make an emergency call may have the following problems: when the terminal device's battery is low, the information reporting process may be interrupted, causing the rescue platform to be unable to obtain accurate location information; when the terminal device is damaged to a certain extent, it cannot support effective emergency calls, resulting in the inability to report location information to the rescue platform; furthermore, regarding the safety hazards of ride-sharing and other shared mobility, if the terminal device is abandoned when making an emergency call, it may be unable to report the correct location information to the rescue platform.

[0077] Using an in-vehicle eCall device to make emergency calls may have the following problems: When the in-vehicle eCall device has insufficient power, the information reporting process may be interrupted, causing the alarm platform to be unable to obtain accurate location information; when the in-vehicle eCall device is damaged to a certain extent, it cannot support effective emergency calls, resulting in the inability to report location information to the alarm platform.

[0078] Based on this, this application provides a multi-device joint calling method. A first device can obtain relevant information about a second device through short-range communication with it, and then send this information, along with the first device's information, to a third device. The third device, based on the obtained information, then sends a paging message to the first device. In this way, if the second device has insufficient power or malfunctions, it can reliably transmit emergency information through the first device. The third device, by parsing the relevant information from both the second and first devices, can send a paging message to the first device and obtain rescue-related information, thereby dispatching personnel for rescue operations.

[0079] The method described in this application is applied to emergency call scenarios, for example, Figure 3 This is a schematic diagram of an emergency call scenario provided in an embodiment of this application, as shown below. Figure 3 As shown, the scenario includes a first device, a second device, and a third device. The first device can be a portable terminal device or a vehicle-mounted device, the second device can be a portable terminal device or a vehicle-mounted device, and the third device can be a device in a public safety answering point (PSAP). The specific content of the first and second devices is related to the scenario of realizing an emergency call.

[0080] For example, in scenario A: a user's vehicle is involved in a collision or other traffic accident. Due to insufficient battery power or damage to the onboard device, it cannot support an effective emergency call. Therefore, an emergency call can be made through the user's portable terminal device. In scenario A, the first device is a portable terminal device, and the second device is an onboard device. The portable terminal device can be a mobile phone or smartwatch, etc., and the onboard device can be an onboard terminal, etc. It is understood that the specific content of the portable terminal device and the onboard device can be set according to the actual application scenario, and this application embodiment does not limit this.

[0081] Scenario B: If a user encounters danger while driving, and their portable terminal device has insufficient battery power or is restricted in use, preventing them from making an effective emergency call, an emergency call can be made through the in-vehicle device. In Scenario B, the first device is the in-vehicle device, and the second device is the portable terminal device. The content of the in-vehicle device and the portable terminal device can be referred to the description above, and will not be repeated here. It is understood that the specific content of the portable terminal device and the in-vehicle device can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0082] Combining scenarios A and B above, in cases where the second device has insufficient power or malfunctions, the first device can assist the second device by making an emergency call through paging with the third device.

[0083] When the second device needs to send information to the first device, the second device can send the information to the first device through a short-range communication link with the first device, so that the first device can forward the information received from the second device to the third device.

[0084] When the first device needs to send information to the third device, the first device will send the information received from the second device and its own information to the third device. The third device will then send a paging message to the first device based on the information received, thus enabling an emergency call.

[0085] It should be noted that the first device includes a communication module and a satellite positioning module, etc., and the second device includes a communication module and a satellite positioning module, etc. It is understood that other modules included in the first and second devices can be set according to the actual application scenario, and this application embodiment does not limit them.

[0086] The communication module has a short-range communication function, which is used for the first device to establish short-range communication with the second device, so that the first device can receive relevant information of the second device from the second device through the short-range communication link; or, it is used for the second device to establish short-range communication with the first device, so that the second device can send relevant information of the second device to the first device through the short-range communication link.

[0087] The satellite positioning module has positioning capabilities and can locate the first or second device via BeiDou satellites and / or the Global Positioning System (GPS).

[0088] For example, when a vehicle is involved in a traffic accident such as a collision, the satellite positioning module of the first device sends a location information request to the GPS, triggering the GPS to acquire location information, thereby achieving the positioning of the first device. It is understood that the specific implementation method of GPS acquiring location information is not limited in the embodiments of this application.

[0089] It should be noted that the process by which the satellite positioning module of the second device locates the second device is similar to the process by which the satellite positioning module of the first device locates the first device, and will not be described again here. It is understood that the method by which the satellite positioning module of the second device locates the second device can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0090] The technical solutions of this application and how they solve the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be implemented independently or in combination with each other. The same or similar concepts or processes may not be described again in some embodiments.

[0091] For example, Figure 4 This is a flowchart illustrating a multi-device joint calling method provided in an embodiment of this application, as shown below. Figure 4 As shown, the following steps may be included:

[0092] S401: The first device establishes short-range communication with the second device.

[0093] In this embodiment of the application, short-range communication is used to transmit messages between the first device and the second device, thereby realizing information sharing; one possible way for the first device to establish short-range communication with the second device is: the first device establishes short-range communication with the second device based on Bluetooth.

[0094] For example, when both the first and second devices have Bluetooth enabled, the first device searches for devices within a first range. Upon finding the second device, the first device inputs a personal identification number (PIN) associated with the second device. If the PIN is entered correctly, the first and second devices successfully connect, establishing short-range communication. The first range can refer to a 50-meter radius around the first device. It is understood that the specific content of the first range can be set according to the actual application scenario, and this application embodiment does not limit it. The specific implementation method of the first device establishing short-range communication with the second device based on Bluetooth is not limited in this application embodiment.

[0095] For example, taking scenario A above as an example, the first device is a portable terminal device and the second device is an in-vehicle device. Then S401 can be described as: the portable terminal device establishes short-range communication with the in-vehicle device. The implementation method of the portable terminal device establishing short-range communication with the in-vehicle device can be adapted to the above description, or it can be set according to the actual application scenario. This application embodiment does not limit it.

[0096] Taking scenario B above as an example, the first device is an in-vehicle device and the second device is a portable terminal device. S401 can be described as: the in-vehicle device establishes short-range communication with the portable terminal device. The implementation method of establishing short-range communication between the in-vehicle device and the portable terminal device can be adapted to the above description or set according to the actual application scenario. This application embodiment does not limit it.

[0097] S402: The first device obtains relevant information about the second device through short-range communication.

[0098] In this embodiment of the application, the second device can be a portable terminal device or a vehicle-mounted device, etc. Therefore, the specific content of the relevant information of the second device is also different when the second device is different.

[0099] For example, in scenario A above, if the second device is a vehicle-mounted device, then the relevant information of the second device includes one or more of the following: the location information of the second device, the timestamp information related to the second device, the identification number of the second device, or the trajectory information of the second device, etc.

[0100] The location information of the second device is used to indicate the location of the vehicle-mounted device, and may include the longitude and latitude of the vehicle-mounted device, or it can be understood as the location information of the second device used to indicate the location of the user. Possible implementations include the longitude, latitude, and elevation of the vehicle-mounted device. The timestamp information related to the second device may include the time when the vehicle-mounted device sent relevant information. The identification number of the second device may include the vehicle identification number (VIN), which may include information such as the vehicle's manufacturer, year, model, body style, or assembly location. The trajectory information of the second device may include route information formed by the vehicle's movement. It is understood that the specific content of the relevant information of the second device can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0101] In scenario B above, the second device is a portable terminal device. The relevant information of the second device includes one or more of the following: the location information of the second device, timestamp information related to the second device, contact information of the second device, trajectory information of the second device, or the reason why the second device is assisted in calling the third device, etc. It is understood that the specific content of the relevant information of the second device can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0102] The location information, timestamp information, or trajectory information of the second device can be adapted to the above description and will not be repeated here. The contact information of the second device may include the mobile phone number of the portable terminal device, contact information on the portable terminal device, or the number dialed by the user using the portable terminal device. The reason for the second device being assisted in calling the third device is used to indicate that the second device has an anomaly, which may include the detection of a collision event or the detection of a distress event. It is understood that the specific content of the relevant information of the second device can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0103] In a possible implementation, the relevant information of the second device may also include frequency indication information. This way, after the first device obtains the relevant information of the second device, the first device can send information to the third device at that frequency. For example, the frequency could be 10 Hz. It is understood that the specific value of the frequency can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0104] In this embodiment of the application, the first device obtains relevant information about the second device through short-range communication, which may include the following possible implementation methods:

[0105] In the first possible implementation, the first device periodically receives relevant information from the second device based on short-range communication.

[0106] For example, during the user's driving of the vehicle, the second device collects relevant information. Since the first device establishes short-range communication with the second device, the second device can periodically send its relevant information to the first device via the short-range communication link. The periodic interval can be 5 minutes, so the second device can receive relevant information from the second device every 5 minutes. It is understood that the specific value of the periodic interval can also be set according to the actual application scenario, and this application embodiment does not limit it; the specific implementation method of the first device periodically receiving relevant information from the second device based on short-range communication is not limited in this application embodiment.

[0107] In the second possible implementation, based on certain triggering conditions, the first device receives relevant information from the second device via short-range communication.

[0108] For example, during the user's driving of the vehicle, the second device collects relevant information. If the triggering condition is a vehicle collision, the second device sends its relevant information to the first device based on short-range communication between the two devices. Thus, the first device receives the relevant information from the second device. It is understood that the specific content of the triggering condition can also be set according to the actual application scenario, and this embodiment does not limit it.

[0109] For example, taking scenario A above as an example, the first device is a portable terminal device and the second device is an in-vehicle device. Then S402 can be described as: the portable terminal device obtains relevant information of the in-vehicle device through short-range communication. The implementation method of the portable terminal device obtaining relevant information of the in-vehicle device through short-range communication can refer to the above description or be set according to the actual application scenario. This application embodiment does not limit it.

[0110] Taking scenario B above as an example, the first device is an in-vehicle device and the second device is a portable terminal device. S402 can be described as: the in-vehicle device obtains relevant information of the portable terminal device through short-range communication. The implementation method of the in-vehicle device obtaining relevant information of the portable terminal device through short-range communication can be adapted to the above description or set according to the actual application scenario. This application embodiment does not limit it.

[0111] S403: The first device sends relevant information about the second device and relevant information about the first device to the third device.

[0112] In this embodiment of the application, the first device can be a portable terminal device or an in-vehicle device, etc. Therefore, the content of the relevant information of the first device is different when the first device is different.

[0113] For example, in scenario A above, the first device is a portable terminal device. The content of the relevant information of the first device is similar to the content of the relevant information when the second device is a portable terminal device, and will not be repeated here. It can be understood that the specific content of the relevant information of the first device can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0114] In scenario B above, the first device is an in-vehicle device. The content of the relevant information of the first device is similar to that of the second device when it is an in-vehicle device, and will not be repeated here. In a possible implementation, the relevant information of the first device may also include the contact information of the first device, which is the same as the contact information of the second device when it is a portable terminal device. It is understood that the specific content of the relevant information of the first device can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0115] Specifically, one possible implementation of the first device sending relevant information about the second device and relevant information about the first device to the third device is as follows: the first device periodically sends relevant information about the second device and relevant information about the first device to the third device.

[0116] For example, since the first device periodically receives relevant information from the second device, after receiving and collecting the relevant information from the second device, the first device can also periodically send the relevant information from the second device and the relevant information from the first device to the third device. The periodic interval can be 7 minutes, so the third device can receive the relevant information from the first device every 7 minutes. It is understood that the specific value of the periodic interval can also be set according to the actual application scenario, and this application embodiment does not limit it; the specific implementation method of the first device sending the relevant information from the second device and the relevant information from the first device to the third device is not limited in this application embodiment.

[0117] For example, taking scenario A above as an example, the first device is a portable terminal device, the second device is an in-vehicle device, and the third device is a PSAP. Then S403 can be described as: the portable terminal device sends relevant information about the in-vehicle device and relevant information about the portable terminal device to the PSAP. The implementation method of the portable terminal device sending relevant information about the in-vehicle device and relevant information about the portable terminal device to the PSAP can be adapted to the above description, or it can be set according to the actual application scenario. This application embodiment does not limit it.

[0118] Taking scenario B above as an example, the first device is an in-vehicle device, the second device is a portable terminal device, and the third device is a PSAP. Then, S403 can be described as: the in-vehicle device sends relevant information of the portable terminal device and relevant information of the in-vehicle device to the PSAP. The implementation method of the in-vehicle device sending relevant information of the portable terminal device and relevant information of the in-vehicle device to the PSAP can refer to the above description or be set according to the actual application scenario. This application embodiment does not limit it.

[0119] S404: The first device receives a paging from the third device.

[0120] In this embodiment, paging may include paging for voice calls, etc. Based on this paging, the first device can automatically connect to hands-free calling and start collecting voice information inside the vehicle, thereby enabling the first device to report the surrounding situation to the third device in a timely manner. It is understood that the specific content of the paging can also be set according to the actual application scenario, and this embodiment does not limit it.

[0121] In this embodiment, the paging is sent by the third device based on the relevant information of the second device and the relevant information of the first device. Therefore, a possible implementation of the first device receiving the paging from the third device is as follows: the third device sends a paging to the first device based on the relevant information of the second device and the relevant information of the first device, and the first device receives the paging from the third device.

[0122] For example, after receiving relevant information from the second device and relevant information from the first device, the third device parses the relevant information from the first device and the relevant information from the second device. If the third device sends a paging request to the second device, but the second device does not respond, the third device can send a paging request to the first device, and the first device receives the paging request from the third device. It is understood that the specific implementation of the first device receiving the paging request from the third device is not limited in this application embodiment.

[0123] For example, after receiving relevant information from the second device and relevant information from the first device, the third device directly sends a paging message to the first device by parsing the relevant information from the first and second devices. Accordingly, the first device receives the paging message from the third device. It is understood that the specific implementation of the first device receiving the paging message from the third device can be set according to the actual application scenario, and this application embodiment does not limit it.

[0124] For example, taking scenario A above as an example, the first device is a portable terminal device and the third device is a PSAP. Then S404 can be described as: the portable terminal device receives a paging from the PSAP. The implementation method of the portable terminal device receiving the paging from the PSAP can be adapted to the above description or set according to the actual application scenario. This application embodiment does not limit it.

[0125] Taking scenario B above as an example, the first device is an in-vehicle device and the third device is a PSAP. S404 can be described as: the in-vehicle device receives a paging from the PSAP. The implementation of the in-vehicle device receiving a paging from the PSAP can be adapted to the above description or set according to the actual application scenario. This application embodiment does not limit it.

[0126] In summary, in this embodiment of the application, the first device can forward relevant information of the first device through short-range communication with the second device, thereby enabling reliable transmission of emergency information. This allows the third device to send a paging message to the first device by parsing the relevant information of the second device and the first device, and to obtain information related to the rescue, thereby dispatching personnel to carry out the rescue.

[0127] exist Figure 4Based on the embodiments shown, taking scenario A above as an example, exemplarily, Figure 5 This is a flowchart illustrating a multi-device joint calling method provided in an embodiment of this application. In this embodiment, the first device is a portable terminal device, the second device is an in-vehicle device, and the third device is a PSAP. The portable terminal device can assist the in-vehicle device in calling the PSAP, or it can be understood that the in-vehicle device can be assisted by the portable terminal device in calling the PSAP.

[0128] like Figure 5 As shown, the following steps may be included:

[0129] S501: The vehicle-mounted device sends a connection establishment request to the portable terminal device.

[0130] In this embodiment, the connection establishment request includes a request reason, which may include at least one of the following: the second device detected a collision event, the second device has insufficient battery power, or the second device is the assisted device. It is understood that the specific content of the request reason can also be set according to the actual application scenario, and this embodiment does not limit it.

[0131] The second device detecting a collision event can be understood as follows: if the vehicle-mounted device detects that the impact force of the collision is greater than or equal to a first threshold through the collision sensor, then the vehicle-mounted device has detected a collision event. The specific value of the first threshold can be set according to the actual application scenario, and is not limited in this embodiment.

[0132] The insufficient power of the second device can be understood as: the power of the vehicle device is less than the second threshold; the specific value of the second threshold can be set according to the actual application scenario, and is not limited in this application embodiment.

[0133] In this context, the second device being the assisted device can be understood as follows: if the vehicle-mounted device experiences an abnormal situation, it can make an emergency call with the assistance of other devices. In this case, the vehicle-mounted device is the assisted device, and the other devices are the assisting devices. The abnormal situation may include situations such as insufficient battery power of the vehicle-mounted device. It is understood that the specific content of the abnormal situation can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0134] In this embodiment of the application, the vehicle-mounted device sends a connection establishment request to the portable terminal device. A possible implementation method is that the second device automatically triggers the sending of the connection establishment request based on preset conditions.

[0135] For example, when the preset condition is that the vehicle-mounted device fails to call PSAP, the vehicle-mounted device can automatically trigger the sending of a connection establishment request; it is understood that the specific implementation method of the vehicle-mounted device sending a connection establishment request to the portable terminal device is not limited in the embodiments of this application.

[0136] It should be noted that the specific content of the preset conditions can be the same as at least one of the reasons for the request, and the specific content of the preset conditions can also be set according to the actual application scenario. This application embodiment does not limit this.

[0137] In this embodiment of the application, a possible implementation method for the vehicle-mounted device to send a connection establishment request to the portable terminal device is as follows: the vehicle-mounted device sends a connection establishment request to the portable terminal device through Bluetooth, Wi-Fi, vehicle-to-everything (V2X) wireless communication technology, wireless fidelity (WIFI) or other methods.

[0138] For example, when both the portable terminal device and the in-vehicle device have Bluetooth enabled, the in-vehicle device searches for devices within a second range. After finding the portable terminal device, the in-vehicle device sends a connection establishment request to the portable terminal device by entering a PIN associated with the portable terminal device. If the PIN is entered correctly, the in-vehicle device can send a connection establishment request to the portable terminal device. The second range can refer to a 30-meter radius around the in-vehicle device. It is understood that the specific content of the second range can be set according to the actual application scenario, and this application embodiment does not limit it. The specific implementation method of the in-vehicle device sending a connection establishment request to the portable terminal device via Bluetooth is not limited in this application embodiment.

[0139] S502: The portable terminal device verifies the identity of the vehicle-mounted device based on the connection establishment request and the first subscription information.

[0140] In this embodiment of the application, the first contract information includes at least one assisted device that is permitted to assist in calling PSAP; it is understood that the specific content of the first contract information can also be set according to the actual application scenario, and this embodiment of the application does not limit it.

[0141] In this embodiment of the application, the first contract information also includes the condition that the portable terminal device allows the establishment of short-range communication. Therefore, the portable terminal device verifies the identity of the vehicle device according to the connection establishment request and the first contract information. A possible implementation is that the vehicle device's identity verification is successful when the request reason and conditions match and at least one assisted device includes the vehicle device.

[0142] For example, if the conditions for a portable terminal device to establish short-range communication include at least one of the request reasons, and at least one assisted device in the portable terminal device assisting in calling PSAP includes an in-vehicle device, then it is determined that the request reason matches the conditions, and at least one assisted device includes an in-vehicle device, thereby the authentication of the in-vehicle device is successful.

[0143] S503: Once the on-board device's authentication is successful, the portable terminal device establishes short-range communication with the on-board device.

[0144] For example, after the authentication of the in-vehicle device is successful, the portable terminal device can establish short-range communication with the in-vehicle device via Bluetooth. The implementation method for the portable terminal device to establish short-range communication with the in-vehicle device via Bluetooth can be found in the description of S401, and will not be repeated here. It is understood that the implementation method for the portable terminal device to establish short-range communication with the in-vehicle device can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0145] S504: The vehicle-mounted device sends relevant information about the vehicle-mounted device to the portable terminal device.

[0146] Correspondingly, the portable terminal device receives relevant information from the vehicle-mounted equipment.

[0147] S505: The portable terminal device sends relevant information about the vehicle-mounted device and the portable terminal device to the PSAP.

[0148] Accordingly, PSAP receives relevant information from the vehicle-mounted device and the portable terminal device. The content of the relevant information from the vehicle-mounted device and the portable terminal device can be found in the description above, and will not be repeated here.

[0149] S506: PSAP sends a paging message to the portable terminal device based on the relevant information of the vehicle-mounted equipment and the portable terminal device.

[0150] In this embodiment of the application, a possible implementation of the PSAP sending a paging message to the portable terminal device based on the relevant information of the vehicle-mounted device and the relevant information of the portable terminal device is as follows: if the PSAP does not respond to the paging message sent to the vehicle-mounted device, it sends a paging message to the portable terminal device.

[0151] For example, after receiving information from the portable terminal device, the PSAP can establish a link connection with the vehicle device to enable voice communication. When the vehicle device cannot connect due to insufficient power or abnormality, the PSAP sends a paging message to the portable terminal device to enable an emergency call.

[0152] S507: Portable terminal devices automatically open and answer calls based on paging.

[0153] In this embodiment, the call can be answered hands-free. In this way, when the user is unable to use the portable terminal device for voice calls due to injury, the portable terminal device can automatically answer the paging from the PSAP, realizing emergency hands-free calling. This allows the PSAP to collect voice information based on the hands-free call, understand the situation around the portable terminal device, and improve rescue efficiency.

[0154] It should be noted that after the portable terminal device PSAP sends relevant information about the vehicle-mounted device and the portable terminal device, the portable terminal device can automatically turn on the call.

[0155] It should be noted that S501 and S502, S504 and S507 in the embodiments of this application are optional steps. One or more optional steps can be set according to the actual application scenario. The order of the steps in the embodiments of this application can also be adjusted according to the actual application scenario. The embodiments of this application do not make specific limitations in this regard.

[0156] In summary, in this embodiment, the portable terminal device receives a connection establishment request from the vehicle-mounted device. Based on the connection establishment request and the first subscription information, and after verifying the identity of the vehicle-mounted device, the portable terminal device establishes short-range communication with the vehicle-mounted device. This allows the vehicle-mounted device to send relevant information to the portable terminal device, which in turn sends relevant information about both the vehicle-mounted device and itself to the PSAP. In this way, if the PSAP receives no response to a paging request from the vehicle-mounted device, it can send a paging request to the portable terminal device. Since the portable terminal device automatically enables answering, it can automatically answer the paging request from the PSAP, enabling hands-free emergency calls. This ensures that emergency calls can be made through the portable terminal device even when the vehicle-mounted device has insufficient power.

[0157] exist Figure 4 Based on the illustrated embodiments, taking scenario B above as an example, exemplarily, Figure 6 This is a flowchart illustrating a multi-device joint calling method provided in an embodiment of this application. In this embodiment, the first device is an in-vehicle device, the second device is a portable terminal device, and the third device is a PSAP. The in-vehicle device can assist the portable terminal device in calling the PSAP, or it can be understood that the portable terminal device can be assisted by the in-vehicle device in calling the PSAP.

[0158] like Figure 6 As shown, the following steps may be included:

[0159] S601: The portable terminal device sends a connection establishment request to the vehicle-mounted device.

[0160] In this embodiment, the connection establishment request includes a request reason, which may include at least one of the following: the second device detects a distress event, the second device has insufficient power, or the second device is the device being assisted. It is understood that the specific content of the request reason can also be set according to the actual application scenario, and this embodiment does not limit it.

[0161] The detection of a distress call by the second device can be understood as follows: when a user makes a phone call to the alarm platform via a portable terminal device, the portable terminal device detects the distress call. It is understood that the specific implementation method of the portable terminal device detecting a distress call is not limited in this embodiment.

[0162] The insufficient power of the second device can be understood as: the power of the user's portable terminal device is less than the third threshold. The specific value of the third threshold can be set according to the actual application scenario, and this application embodiment does not limit it.

[0163] In this context, the second device being the assisted device can be understood as follows: if the portable terminal device experiences an abnormal situation, and can make an emergency call with the assistance of other devices, then the portable terminal device is the assisted device, and the other devices are the assisting devices. The abnormal situation may include situations such as insufficient battery power of the portable terminal device. It is understood that the specific content of the abnormal situation can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0164] It should be noted that when a user taking a ridesharing call to the emergency platform via a portable terminal device, even if the call is disconnected and the location information of the portable terminal device remains unchanged, the portable terminal device can still make an emergency call through the onboard equipment in the ridesharing vehicle because it has detected a distress event.

[0165] In this embodiment, the implementation method of the portable terminal device sending a connection establishment request to the vehicle device can be referred to the description of S501, and will not be repeated here; it can be understood that the implementation method of the portable terminal device sending a connection establishment request to the vehicle device can also be set according to the actual application scenario, and this embodiment does not limit it.

[0166] S602: The vehicle-mounted device verifies the identity of the portable terminal device based on the connection establishment request and the first contract information.

[0167] In this embodiment of the application, S602 can be referred to Figure 5 The corresponding content of S502 is described in detail here;

[0168] It should be noted that when verifying the identity of a portable terminal device, if the user is taking a rideshare, the identity of the user's portable terminal device can be verified through the mobile phone information registered when the user takes the rideshare; or, the identity of the portable terminal device can be verified through the mobile phone information of the rideshare driver, which includes location information, etc. Therefore, the device within a third range can be located through the location information to verify the identity of the portable terminal device; the third range can refer to a range of 15 meters around the location information. It can be understood that the specific content of the third range can also be set according to the actual application scenario, and this application embodiment does not limit it.

[0169] S603: Once the portable terminal device has been authenticated, the vehicle-mounted device establishes short-range communication with the portable terminal device.

[0170] S604: The portable terminal device sends relevant information about the portable terminal device to the vehicle-mounted device.

[0171] S605: The vehicle-mounted equipment sends relevant information about the portable terminal device and the vehicle-mounted equipment to the PSAP.

[0172] S606: PSAP sends a paging message to the vehicle-mounted device based on the relevant information of the portable terminal device and the vehicle-mounted device.

[0173] S607: The vehicle-mounted equipment automatically turns on and answers calls based on paging.

[0174] In the embodiments of this application, S603-S607 can be referred to Figure 5 The content of S503-S507 of the illustrated embodiment is adapted and described, and will not be repeated here. Figure 5 The embodiment shown differs from the one described above in that... Figure 6 In the embodiment shown, the first device is an in-vehicle device, and the second device is a portable terminal device.

[0175] In summary, in this embodiment, the vehicle-mounted device receives a connection establishment request from a portable terminal device. Based on the connection establishment request and the first subscription information, and after verifying the identity of the portable terminal device, the vehicle-mounted device establishes short-range communication with the portable terminal device. This allows the portable terminal device to send relevant information to the vehicle-mounted device, which in turn sends relevant information about both the vehicle-mounted device and the portable terminal device to the PSAP. The PSAP can then send a paging message to the vehicle-mounted device based on this information. Since the vehicle-mounted device automatically enables answering, it can automatically answer the paging message from the PSAP, enabling hands-free emergency calls. This ensures that emergency calls can be made through the vehicle-mounted device even when the portable terminal device has insufficient power.

[0176] exist Figures 4-6 Based on the illustrated embodiments, exemplarily, Figure 7 This is a flowchart illustrating a multi-device joint call method provided in an embodiment of this application. The method in this embodiment can be executed before S401, S501, or S601, such as... Figure 7 As shown, the following steps may be included:

[0177] S701: The second device sends a short-range communication request to the third device.

[0178] Accordingly, the third device receives a short-range communication request from the second device. The short-range communication request is used by the second device to request the establishment of short-range communication with the first device, thereby enabling the second device to send relevant information of the second device to the first device based on the established short-range communication. The implementation method of the second device sending a short-range communication request to the third device is not limited in this application embodiment.

[0179] For example, taking scenario A above as an example, if the second device is an in-vehicle device and the third device is a PSAP, then S701 can be described as: the in-vehicle device sends a short-range communication request to the PSAP; wherein, the specific implementation method of the in-vehicle device sending a short-range communication request to the PSAP is not limited in the embodiments of this application.

[0180] Taking scenario B above as an example, if the second device is a portable terminal device and the third device is a PSAP, then S701 can be described as: the portable terminal device sends a short-range communication request to the PSAP; wherein, the specific implementation method of the portable terminal device sending a short-range communication request to the PSAP is not limited in the embodiments of this application.

[0181] S702: The third device verifies the identity of the first device based on the short-range communication request and the second contract information.

[0182] In this embodiment, the second contract information is used to indicate at least one assisting device that allows the second device to call the third device. It is understood that the specific content of the second contract information can also be set according to the actual application scenario, and this embodiment does not limit it.

[0183] In this embodiment, a possible implementation of the third device verifying the identity of the first device based on the short-range communication request and the second contract information is as follows: if the first device is an assisting device, the first device's identity verification is successful. For example, if the second contract information includes the first device's identity information, thus determining that the first device is an assisting device, then the first device's identity verification is successful.

[0184] For example, taking scenario A above as an example, the first device is a portable terminal device and the third device is a PSAP. Then S702 can be described as: the PSAP verifies the identity of the portable terminal device based on the short-range communication request and the second contract information. The implementation method of the PSAP verifying the identity of the portable terminal device based on the short-range communication request and the second contract information can be adapted to the above description or set according to the actual application scenario. This application embodiment does not limit it.

[0185] Taking scenario B above as an example, the first device is an in-vehicle device and the third device is a PSAP. S702 can be described as follows: the PSAP verifies the identity of the in-vehicle device based on the short-range communication request and the second contract information.

The following describes a multi-device joint calling apparatus provided in the embodiments of this application for executing the above-described methods. Those skilled in the art will understand that the methods and apparatuses can be combined and referenced together. One multi-device joint calling apparatus provided in the embodiments of this application can execute the steps of the first device in the above-described multi-device joint calling method; another multi-device joint calling apparatus can execute the steps executed by the second device in the above-described multi-device joint calling method; and yet another multi-device joint calling apparatus can execute the steps executed by the third device in the above-described multi-device joint calling method.

[0196] The following example illustrates how functional modules are divided according to their respective functions:

[0197] For example, Figure 8This is a schematic diagram of a multi-device joint calling device provided in an embodiment of this application. The multi-device joint calling device 80 can be a first device, a second device, or a third device in the embodiment of this application, or it can be a component, chip, or chip system applied in the first device, the second device, or the third device.

[0198] like Figure 8 As shown, the multi-device joint calling device 80 includes a processing unit 801 and a communication unit 802; wherein, the communication unit 802 is used to support the multi-device joint calling device in performing the steps of sending or receiving information, and the processing unit 801 is used to support the multi-device joint calling device in performing the steps of processing information.

[0199] For example, taking a multi-device joint calling device applied to a first device as an example, the processing unit is used to establish short-range communication with the second device; the communication unit is used to obtain relevant information of the second device based on the short-range communication; the communication unit is used to send relevant information of the second device and relevant information of the first device to a third device; the communication unit is used to receive a paging from the third device; wherein, the paging is sent by the third device based on the relevant information of the second device and the relevant information of the first device.

[0200] In one possible implementation, the communication unit is specifically configured to receive a connection establishment request from the second device; the processing unit is specifically configured to verify the identity of the second device based on the connection establishment request and first subscription information, wherein the first subscription information is used to indicate at least one assisted device that is allowed to assist the first device in calling the third device; and the processing unit is specifically configured to establish short-range communication with the second device if the second device's authentication is successful.

[0201] In one possible implementation, the connection establishment request includes a request reason, and the first subscription information also includes conditions under which the first device allows the establishment of short-range communication; the processing unit is specifically configured to: when the request reason and conditions match, and at least one assisted device includes the second device, the authentication of the second device is successful.

[0202] In one possible implementation, the request reason includes at least one of the following: the second device detects a collision event, the second device detects a distress event, the second device has insufficient power, or the second device is the device being assisted.

[0203] In one possible implementation, paging refers to paging for voice calls, and the processing unit is specifically used to automatically initiate and answer calls based on paging.

[0204] In one possible implementation, the above-mentioned call is a hands-free call.

[0205] In one possible implementation, the communication unit is further configured to receive a short-range communication function activation instruction from a third device; the processing unit is further configured to activate the short-range communication function of the first device according to the short-range communication function activation instruction.

[0208] For example, taking a multi-device joint calling device applied to a third device as an example, the communication unit can be understood as a receiving unit and a sending unit. The receiving unit is used to receive a paging request message from the first device. The paging request message includes relevant information of the first device and relevant information of the second device. The sending unit is used to send a paging message to the first device according to the paging request message.

[0209] In one possible implementation, the sending unit is specifically configured to send a paging message to the first device if there is no response when a paging message is sent to the second device.

[0210] In one possible implementation, the receiving unit is further configured to receive a short-range communication request from the second device; the processing unit is configured to verify the identity of the first device based on the short-range communication request and the second subscription information, wherein the second subscription information is used to indicate at least one assisting device that is allowed to assist the second device in calling the third device; and the sending unit is specifically configured to send a short-range communication function activation instruction to the first device when the authentication of the first device is successful.

[0211] In one possible implementation, the processing unit is specifically used to: when the first device is an assisting device, verify the authentication of the first device.

[0212] In one possible implementation, the relevant information of the first device includes one or more of the following: the location information of the first device, timestamp information related to the first device, contact information of the first device, identification number of the first device, or trajectory information of the first device; or,

[0214] In one possible implementation, paging is for voice calls.

[0215] For example, taking a multi-device joint calling device applied to a second device as an example, the communication unit is used to send a connection establishment request to the first device; the processing unit is used to establish short-range communication with the first device according to the connection establishment request; and the communication unit is used to send relevant information of the second device to the first device based on the short-range communication.

[0216] The connection establishment request includes a request reason, which may include at least one of the following: the second device detected a collision event, the second device detected a distress event, the second device has insufficient power, or the second device is the device being assisted.

[0217] In one possible implementation, the communication unit is also used to send short-range communication requests to a third device.

[0218] In one possible implementation, the relevant information of the second device includes one or more of the following: the location information of the second device, the timestamp information associated with the second device, the contact information of the second device, the identification number of the second device, the trajectory information of the second device, or the reason why the second device is assisted in calling the third device.

[0219] In one possible implementation, the communication unit is specifically used to automatically trigger the sending of a connection establishment request based on preset conditions.

[0220] In one possible embodiment, the multi-device joint calling device may further include a storage unit 803. The processing unit 801, the communication unit 802, and the storage unit 803 are connected via a communication bus.
