[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution 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 part of the embodiments of the present application, not all of the embodiments.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0051] The present application provides a multi-network integrated emergency call response method and device, which can intelligently select a communication link according to the actual communication link and the specific circumstances of the communication information to be transmitted, which is conducive to ensuring the timeliness and reliability of emergency communication.

[0052] Figure 1 A schematic diagram of an exemplary operating environment in which embodiments of the present application can be implemented is shown.

[0053] Reference Figure 1 The operating environment includes a server 110 and a terminal device 120 (only one is shown in the figure). In a specific emergency command scenario, there are multiple levels of command centers and protected objects (residents), among which the server 110 is used by the top-level command center, and the terminal device 120 is used by other levels of command centers and protected objects.

[0054] The terminal device 120 has a first communication module and a second communication module, wherein the first communication module includes a public network communication unit and a satellite communication unit, the public network communication unit is such as a 4G module, a 5G module, etc., the satellite communication unit is such as a Beidou module, etc., and the second communication module is an ad hoc network communication module, including such as a Bluetooth module, a WiFi module, a lora communication module, etc. The terminal device 120 can be directly connected to the server 110 using the first communication module, and can be connected to other terminal devices 120 within a certain range using the second communication module.

[0055] The terminal device 120 also includes basic display functions, sound pickup functions, and positioning functions, and may also include other functions necessary for emergency situations, such as waterproof and shockproof functions, communication encryption functions, and solar charging functions. In short, the terminal device 120 can support calls between different terminal devices 120 or between the server 110 and the terminal device 120.

[0056] In the first aspect, the present application provides a multi-network integrated emergency call response method. The method can be Figure 1 The server 110 in is implemented.

[0057] Reference Figure 1 , the method specifically comprises the following steps:

[0058] S210: Acquire distance information between the sender and the receiver as well as the first communication link and the second communication link.

[0059] In the embodiment of the present application, the sender refers to the terminal device 120 that sends the communication information, and the receiver refers to the sender's target terminal device 120. In the emergency call-response process, both the caller and the responder may call and respond, so the sender and the receiver refer to the role of the terminal device 120 in a call or response process, and the entire communication process can be understood by analogy.

[0060] The first communication link includes a public communication network and / or a satellite communication network, and the second communication link includes an ad hoc communication network relying on multiple relay parties;

[0061] In the embodiment of the present application, the sender and the receiver are both one of the terminal devices 120, and the sender and the receiver can establish a communication connection through the first communication link and the second communication link. Of course, the first communication link is a fixed link. After the link is established, the transmission path is the communication information sent by the sender to the receiver via the server 110. The second communication link is a temporary link, which requires the sender and the receiver to temporarily establish the second communication link through the second communication module of several intermediate devices between the sender and the receiver. Of course, the first communication link and the second communication link can both realize the transmission of communication information after they are established.

[0062] Since both the sender and the receiver have positioning functions and both the sender and the receiver can connect to the server 110, the server 110 can obtain the first location information of the sender and the second location information of the receiver.

[0063] S220: Determine a second communication duration of the second communication link according to the distance information.

[0064] The second communication duration mentioned here refers to the duration required for the second communication link to transmit a test packet of a unit size. The second communication link is implemented by the second communication module of several terminal devices 120 between the sender and the receiver. The transmission process of the test packet is the same as the actual communication information transmission process. After the terminal device 120 of the previous node on the second communication link receives the test packet, it processes and identifies the test packet and then forwards it to the terminal device 120 of the next node. Since the test packet and the actual communication information are both small, it can be considered that the transmission time between nodes can be ignored, and the main time consumed is in the process of processing, identifying and forwarding. At the same time, the communication distance of the second communication module is limited. Therefore, if the distance information between the sender and the receiver is farther, the more terminal devices 120 of the intermediate nodes are required, and the more processing, identification and forwarding processes are required, the longer the second communication duration is. Therefore, it can be considered that the second communication duration is proportional to the distance information city. The larger the distance information, the longer the second communication duration.

[0065] S230: Select a communication link according to the second communication duration, the pre-acquired first communication duration of the first communication link, and the pre-acquired urgency data of the communication information to be transmitted.

[0066] The first communication link is implemented by relying on a public network or a satellite communication network, and the influence of the communication distance is basically negligible, so it can be considered that the first communication duration can be basically determined in advance, that is, pre-acquired.

[0067] The second communication duration has been obtained in the previous step.

[0068] Before the communication link is selected, the communication information to be transmitted has been determined, so the sending timestamp, importance level and data description tag carried by the communication information to be transmitted can be obtained. Therefore, the method for obtaining the urgency data includes: assuming that the interval between the sending timestamp carried by the communication information to be transmitted and the current time is , the importance level carried is p, there are n data description tags carried, and the urgency coefficient of pre-acquisition relative to the i-th data description tag is , , the urgency data is z, then , where is a preset constant greater than zero.

[0069] Based on the foregoing, the method of this step specifically includes: when the urgency data is not higher than the urgency threshold, selecting the first communication link for communication;

[0070] When the urgency data is higher than the urgency threshold, if the first communication duration is not greater than the first preset multiple of the second communication duration, the first communication link is selected, and the first preset multiple is greater than 1; if the first communication duration is greater than the second preset multiple of the second communication duration, the second communication link is selected, and the second preset multiple is greater than the first preset multiple; if the first communication duration is greater than the first preset multiple of the second communication duration and not greater than the second preset multiple of the second communication duration, the preference data of the second communication link is calculated, and the second communication link is selected when the preference data is higher than the preference threshold, otherwise the first communication link is selected, and the preference data is positively correlated with the urgency data and the first communication duration, and negatively correlated with the second communication duration. Generally speaking, the first preset multiple is 1.2, and the second preset multiple is 2.5.

[0071] In the above content, the specific calculation method of the preference data includes: assuming that the first communication duration is , the second communication duration is , the preferred degree data is y, then , where q is the pre-acquired link importance coefficient between the sender and the receiver, m is the amount of communication information to be transmitted, and x is the distance information. All are preset constants greater than zero.

[0072] The method for obtaining the urgency coefficient of the data description label includes: pre-constructing a label coefficient comparison table for each data description label, substituting the data description label into the label coefficient comparison table, and obtaining the urgency coefficient. Specifically, the data description label may include an attribute label or a magnitude label. The attribute label is, for example, a data format label, and the magnitude label is, for example, a data volume. All possible data description labels exist in the label coefficient comparison table. If the data description label is an attribute label, the corresponding urgency coefficient is unique and determined. If the data description label is a magnitude label, different urgency coefficients are taken for different magnitude value ranges, so that the urgency coefficient of each data description label can be determined. It should be understood that in the constructed label coefficient comparison table, the urgency coefficient corresponding to each data description label is less than 1 and greater than 0. The comparison relationship between the data description label and the urgency coefficient depends on the data experience. If the urgency reflected by the data description label is higher, the corresponding urgency coefficient is larger.

[0073] The method for obtaining the link importance coefficient includes: obtaining the first location information of the sender and the second location information of the receiver; connecting the first location information and the second location information to determine the ideal link trajectory; determining the division area through which the ideal link trajectory passes based on the pre-constructed emergency zoning map; determining the link importance coefficient based on the preset division importance coefficient relative to each division area. The emergency zoning map is determined relative to the map of the disaster coverage area. The emergency zoning map divides the disaster coverage area into multiple areas, each area corresponds to a division importance coefficient, the first location information and the second location information can both determine a clear point on the map of the disaster coverage area, and the line segment connecting the two is the ideal link trajectory. The ideal link trajectory can be determined on the map of the disaster coverage area, and the area passed can also be determined. After passing through an area, a corresponding division importance coefficient is calculated, and the division importance coefficient of the same area is not repeated, so that the cumulative value of all division importance coefficients can be determined, that is, the link importance coefficient can be determined. Of course, the link importance coefficient can also be equal to the maximum value, minimum value, median value or average value of the division importance coefficients of all areas passing through.

[0074] This method only selects the communication link. The first communication link is a known communication link, while the second communication link may have a preconfigured self-organizing communication link or may not have a preconfigured self-organizing communication link. It is necessary to trigger the establishment of a self-organizing communication link between the sender and the receiver under the intervention of the server. After the stable communication link is established, the communication information to be transmitted is transmitted.

[0075] In summary, the method can determine how to select a communication link based on the specific circumstances of the communication link between the sender and the receiver and the communication information to be transmitted, thereby realizing intelligent selection of the communication link. After intelligently selecting a reasonable communication link, the communication information to be transmitted can be transmitted by establishing the communication link, which is beneficial to ensuring the timeliness and reliability of the transmission of the communication information to be transmitted, that is, it is beneficial to ensuring the timeliness and reliability of the entire call response process. Of course, in order to save processing efficiency, the method may not trigger the selection of a communication link every time a communication information is sent, or it may be considered that the selected communication link is timely and reliable within a preset time period.

[0076] It should be understood that the method is an interpretable machine learning algorithm, in which parameters can be trained based on the timeliness feedback of the communication. The parameters that can be trained are, for example, , label coefficient comparison table, preset duration, urgency threshold, first preset multiple, second preset multiple, etc. During long-term use, the method can be trained so that the method can select the communication link more intelligently and reasonably, which is conducive to further ensuring the timeliness and reliability of the entire call response process.
