However, emergency communication systems often use pre-set communication channels for emergency communication and cannot be adjusted according to real-time network conditions, which is likely to cause communication interruptions in an environment with fluctuating network quality and reduces the reliability of emergency communication.

[0052] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] Please refer to Figure 1 , Figure 1 which is a flowchart of the steps of an emergency command online communication method provided in Embodiment 1 of the present invention.

[0054] An emergency command online communication method provided by the present invention includes:

[0055] Step 101: Obtain the quality of service data between the communication device and each communication channel;

[0056] A communication channel refers to scanning all available communication channels within a certain area range through a frequency hopping scanning algorithm.

[0057] The quality of service data refers to a set of key indicators used to evaluate and optimize the performance of communication channels, including but not limited to signal strength, signal-to-noise ratio, bit error rate, data throughput, and round-trip delay, etc.

[0058] In the embodiment of the present invention, the communication area of the communication device is obtained, and all available communication channels are scanned within a certain area range through a frequency hopping scanning algorithm to obtain the quality of service data between the communication device and each communication channel.

[0059] Step 102: Perform channel allocation for the communication device according to each quality of service data to obtain the emergency communication channel and emergency communication requirement parameters corresponding to the communication device;

[0060] The emergency communication channel refers to the communication channel that is most suitable for the communication device.

[0061] The emergency communication requirement parameters refer to a set of key indicators for quantifying the resource requirements of emergency communication services, including but not limited to the emergency bandwidth occupancy rate and the emergency cache occupancy rate.

[0062] In an embodiment of the present invention, the emergency communication type of a communication device is input into a preset service quality weight list to match the corresponding service quality weight and emergency communication requirement parameters. Based on the service quality weight, weighted operations are respectively performed on each service quality data to obtain multiple service quality scores, and the communication channel associated with the maximum value selected from each service quality score is used as the emergency communication channel corresponding to the communication device.

[0063] Step 103: Obtain multiple communication data packets of the emergency communication channel, and perform queue allocation on each communication data packet to obtain a first-priority queue and multiple second-priority queues.

[0064] The first-priority queue refers to the queue constructed by data packets related to emergency communication.

[0065] The second-priority queue refers to the queue constructed by data packets not related to emergency communication.

[0066] The communication data packet refers to an IP data packet (i.e., an Internet Protocol data packet) in the emergency communication channel.

[0067] In an embodiment of the present invention, the communication identifiers of each communication data packet are respectively extracted, and it is determined whether the communication identifier of each communication data packet is an emergency identifier. If the communication identifier is an emergency identifier, the communication data packet is determined as a first data packet. If the communication identifier is not an emergency identifier, the communication data packet is determined as a second data packet. The first-priority queue is constructed by using each first data packet, and each second data packet is divided into multiple second-priority queues according to the service type of each second data packet.

[0068] Step 104: Perform communication transmission according to the first-priority queue and each second-priority queue, and dynamically adjust each second-priority queue in the emergency communication channel by using the emergency communication requirement parameters.

[0069] In an embodiment of the present invention, communication transmission is performed on the first priority queue and each second priority queue according to the queue bandwidth occupancy ratios of the first priority queue and each second priority queue, and the bandwidth occupancy ratio and cache occupancy ratio of the emergency communication channel are obtained based on a preset time window. It is determined whether the bandwidth occupancy ratio is greater than the emergency bandwidth occupancy ratio. If the bandwidth occupancy ratio is greater than the emergency bandwidth occupancy ratio, the second priority queue with the lowest priority is selected from each second priority queue as the target queue, the communication transmission of the target queue is disconnected, and the step of obtaining the bandwidth occupancy ratio and cache occupancy ratio of the emergency communication channel based on the preset time window is skipped. If the bandwidth occupancy ratio is greater than the emergency bandwidth occupancy ratio, it is determined whether the cache occupancy ratio is greater than the emergency cache occupancy ratio. If the cache occupancy ratio is greater than the emergency cache occupancy ratio, the second priority queue with the lowest priority is selected from each second priority queue as the target queue, the communication transmission of the target queue is disconnected, and the step of obtaining the bandwidth occupancy ratio and cache occupancy ratio of the emergency communication channel based on the preset time window is skipped. If the cache occupancy ratio is less than or equal to the emergency cache occupancy ratio, the step of obtaining multiple communication data packets of the emergency communication channel is skipped.

[0070] In an embodiment of the present invention, by obtaining the quality of service data between a communication device and each communication channel, channel allocation is performed on the communication device according to each quality of service data to obtain the emergency communication channel and emergency communication demand parameters corresponding to the communication device, multiple communication data packets of the emergency communication channel are obtained, each communication data packet is queue-allocated to obtain a first priority queue and multiple second priority queues, communication transmission is performed according to the first priority queue and each second priority queue, and the emergency communication demand parameters are used to dynamically adjust each second priority queue in the emergency communication channel. The technical problem that the traditional emergency communication method mainly uses an independent emergency communication system for emergency communication, cannot be adjusted according to the real-time network condition, is prone to communication interruption in an environment with fluctuating network quality, and reduces the reliability of emergency communication is solved. Compared with the traditional emergency communication method, in the present invention, channel allocation is performed on the communication device according to each quality of service data to obtain the emergency communication channel and emergency communication demand parameters corresponding to the communication device, improving the stability of emergency communication in a harsh environment. At the same time, each second priority queue in the emergency communication channel is dynamically adjusted according to the emergency communication demand parameters, realizing the precise allocation of channel resources in the emergency communication channel and improving the reliability of emergency communication.

[0071] Please refer to Figure 2 , Figure 2 which is a flowchart of the steps of an emergency command online communication method provided in the second embodiment of the present invention.

[0072] An emergency command online communication method provided by the present invention includes:

[0073] Step 201: Obtain the quality of service data between the communication device and each communication channel;

[0074] In the embodiments of the present invention, the quality of service data between the communication device and each communication channel is obtained through a communication operation platform, where the communication operation platform includes, but is not limited to, a mobile switching center or a communication base station controller.

[0075] It should be noted that the distributed network probes deployed in the communication operation platform perform the following measurements on each communication channel. Signal strength: Sampling is performed every 200 milliseconds using a sliding window technique, and the average value within 30 seconds is calculated. Signal-to-noise ratio: The signal and noise components are separated using digital signal processing techniques, and the real-time signal-to-noise ratio is calculated every 500 milliseconds. Bit error rate: By periodically sending a known bit sequence and comparing the received results, the bit error rate is calculated. Data throughput: Monitor the actual data transmission rate and calculate the ratio of the theoretical peak value to the actual value. Round-trip delay: Send a timestamp probe packet and measure the response time, and calculate the delay distribution histogram to obtain the round-trip delay.

[0076] Furthermore, it further includes:

[0077] A1: Obtain the communication area of the communication device, and collect each communication channel within the communication area using the frequency hopping scanning method.

[0078] In the embodiments of the present invention, the communication area of the communication device is obtained, and each communication channel within the communication area is collected based on the frequency hopping scanning method.

[0079] It should be noted that the frequency hopping scanning method is constructed based on software-defined radio technology, which can quickly cover a wide frequency spectrum range from 350 MHz to 6 GHz, including conventional cellular network bands, emergency dedicated bands, satellite communication bands, and shortwave emergency communication bands. At the same time, the scanning results can be shared with the communication operation platform in real time through a secure channel.

[0080] Step 202: Input the emergency communication type of the communication device into a preset quality of service weight list to match the corresponding quality of service weight and emergency communication requirement parameters;

[0081] The emergency communication type refers to the classification of emergency services divided according to communication protocols and application scenarios, and can be obtained by detecting the "Emergency" mark in the SIP (Session Initiation Protocol) call request of the communication device or the emergency identifier of network services on the Internet.

[0082] It should be noted that the quality of service weight list stores the quality of service weights and emergency communication requirement parameters corresponding to different emergency communication types.

[0083] In an embodiment of the present invention, the emergency communication type of a communication device is used to retrieve a preset service quality weight list, and the corresponding service quality weight and emergency communication requirement parameters are matched.

[0084] It is worth mentioning that the service quality weights in the service quality weight list can be set by using the weighted linear combination method.

[0085] Step 203: Perform weighted operations on each service quality data based on the service quality weights to obtain multiple service quality scores, where the service quality data includes signal strength, signal-to-noise ratio, bit error rate, data throughput, and round-trip delay;

[0086] The service quality score refers to an index for quantitatively analyzing the performance of a communication channel.

[0087] In an embodiment of the present invention, the service quality weights and each service quality data are respectively input into a preset linear weighting function to obtain multiple service quality scores, where the service quality data includes signal strength, signal-to-noise ratio, bit error rate, data throughput, and round-trip delay.

[0088] It should be noted that the linear weighting function is specifically:

[0089]

[0090] where is the service quality score, is the first weight coefficient, is the second weight coefficient, is the third weight coefficient, is the fourth weight coefficient, is the fifth weight coefficient, is the signal strength, is the signal-to-noise ratio, is the bit error rate, is the data throughput, is the round-trip delay.

[0091] Step 204: Select the communication channel associated with the maximum value from each service quality score as the emergency communication channel corresponding to the communication device.

[0092] In an embodiment of the present invention, the communication channel associated with the maximum value is selected from all service quality scores as the emergency communication channel corresponding to the communication device.

[0093] Step 205: Obtain multiple communication data packets of the emergency communication channel, and perform queue allocation on each communication data packet to obtain a first priority queue and multiple second priority queues;

[0094] Further, step 205 includes the following sub-steps:

[0095] S11. Extract the communication identifiers of each communication data packet respectively, and determine whether the communication identifiers of each communication data packet are emergency identifiers;

[0096] The communication identifier refers to the ToS (i.e., the service type field) or the (DSCP) differentiated service code point value of the communication data packet.

[0097] The emergency identifier refers to the communication identifier marked with an emergency identifier. For example, the communication identifier is DSCP EF (46) or CS7.

[0098] In the embodiment of the present invention, the communication identifiers of each communication data packet are extracted respectively (the communication identifier is the service type field or the differentiated service code point value), and it is determined whether the communication identifiers of each communication data packet are emergency identifiers.

[0099] S12. If the communication identifier is an emergency identifier, then determine the communication data packet as the first data packet;

[0100] The first data packet refers to an IP data packet with an emergency identifier.

[0101] In the embodiment of the present invention, when the communication identifier is DSCP EF (46) (i.e., the emergency service field) or CS7 (i.e., the emergency differentiated service code point value), then determine the communication data packet as the first data packet.

[0102] S13. If the communication identifier is not an emergency identifier, then determine the communication data packet as the second data packet;

[0103] The second data packet refers to an IP data packet without an emergency identifier.

[0104] In the embodiment of the present invention, if the communication identifier is not DSCP EF (46) or CS7, then determine the communication data packet as the second data packet.

[0105] S14. Construct a first priority queue by using each first data packet;

[0106] In the embodiment of the present invention, sort according to the sending time of each first data packet to obtain the first priority queue.

[0107] S15. Divide each second data packet into multiple second priority queues according to the service type of each second data packet.

[0108] The service type refers to the emergency mark of the second data packet. For example, the "Emergency" mark in the SIP call request (i.e., the session initiation protocol) or the emergency identifier of the network service in the Internet

[0109] In the embodiments of the present invention, each second data packet is divided into multiple second-priority queues according to the service type of each second data packet. For example, when the service type of the second data packet is a critical service, the second data packet is divided into the first second-priority queue; when the service type of the second data packet is a video stream, the second data packet is divided into the second second-priority queue; when the service type of the second data packet is background synchronization, the second data packet is divided into the third second-priority queue.

[0110] It should be noted that the priority of the first second-priority queue is higher than that of the second second-priority queue, the priority of the second second-priority queue is higher than that of the third second-priority queue, and so on. And there are at least three second-priority queues.

[0111] Step 206: Perform communication transmission according to the first-priority queue and each second-priority queue, and dynamically adjust each second-priority queue in the emergency communication channel by using the emergency communication demand parameters.

[0113] S21: Obtain the broadband occupancy rate and the buffer occupancy rate of the emergency communication channel based on a preset time window, and determine whether the broadband occupancy rate is greater than the emergency bandwidth occupancy rate;

[0114] Further, S21 includes the following sub-steps:

[0119] In the embodiments of the present invention, the instantaneous bandwidth data and the instantaneous buffer data of the emergency communication channel are collected by using a preset time window, where the time window includes a 50-ms short window and a 5-s long window.

[0120] S212: Perform mean processing on the instantaneous bandwidth data to obtain a first mean value;

[0121] In the embodiments of the present invention, the instantaneous bandwidth data is input into a preset first mean function to obtain a first mean value.

[0122] It should be noted that the first mean function is specifically as follows:

[0123]

[0124] Wherein, is the first mean, is the number of data points, is the instantaneous bandwidth value at time i, and i is time.

[0125] S213. Perform mean processing on the instantaneous cache data to obtain a second mean;

[0126] In an embodiment of the present invention, the instantaneous cache data is input into a preset second mean function to obtain a second mean.

[0127] It should be noted that the second mean function is specifically as follows:

[0128]

[0129] Wherein, is the second mean, is the instantaneous cache value at time i.

[0130] S214. Perform ratio processing on the first mean and a preset total bandwidth to obtain a bandwidth occupancy rate;

[0131] The total bandwidth refers to the aggregated transmission capacity of all available channels in a communication system.

[0132] The bandwidth occupancy rate refers to the proportion of the currently used communication resources in the total bandwidth.

[0133] In an embodiment of the present invention, the ratio between the first mean and a preset total bandwidth is calculated to obtain a bandwidth occupancy rate.

[0134] S215. Perform ratio processing on the second mean and a preset total cache capacity to obtain a cache occupancy rate.

[0135] The total cache capacity refers to the sum of the maximum physical storage spaces that all cache nodes (such as base stations and core network gateways) in a communication system can store data to be forwarded.

[0136] The cache occupancy rate refers to the proportion of the currently used cache capacity in the total cache capacity in a communication system.

[0137] In an embodiment of the present invention, the ratio between the second mean and a preset total cache capacity is calculated to obtain a cache occupancy rate.

[0139] The emergency bandwidth occupancy rate refers to the preset bandwidth occupancy rate that triggers the release of channel resources. For example, the emergency bandwidth occupancy rate takes a value of 80%.

[0140] The target queue refers to the second-priority queue that needs to disconnect communication transmission.

[0141] In the embodiment of the present invention, when the bandwidth occupancy rate is greater than 80%, it indicates that the communication channel resources of the emergency communication channel are released, and the second-priority queue with the smallest priority is selected from each second-priority queue as the target queue.
