[0053] At present, in the scene of preventing the target person such as the old, the child or the pet from losing, usually, a handheld terminal device such as a smart phone or a smart watch is connected with a server in communication, so as to determine the position information of the target person, and the handheld terminal has problems such as inconvenient to carry and limited battery capacity. The flexible wearable terminal device (passive LoRa terminal) can be sewn on various clothes, such as the clothes and trousers of the old and the child, or the pet clothes and the collar of the pet, to solve the problem of inconvenient to carry. The passive LoRa system uses the LoRa signal widely existing in the environment to realize the far distance high concurrency backscatter communication. The terminal of the passive LoRa system does not need to actively generate a signal and does not need a battery to generate a carrier signal, but uses the signal in the environment to realize the far distance backscatter communication, and the farthest distance reaches 2km. However, the LoRa fixed terminal adopts a polling mode to communicate with the gateway and the server, and cannot meet the condition of following the target task to move. Based on this, the application provides a mobile terminal communication method, which is applied to the LoRa mobile terminal.

[0054] Figure 1 The flowchart of the mobile terminal communication method provided by the application is shown, and the method comprises the following steps:

[0055] S101: receiving the LoRa data packet sent by the preset LoRa signal source.

[0056] Specifically, the LoRa signal source widely exists in the environment and can realize the far distance high concurrency backscatter communication, and the LoRa signal source is preferably co-located with a 4G / 5G wireless base station. The LoRa mobile terminal uses the signal of the LoRa signal source in the environment to realize the far distance backscatter communication, and does not need to actively generate a signal. The LoRa data packet comprises a preamble, a delimiter and data.

[0057] S102: determining the pilot strength of the LoRa data packet, and determining the target spreading factor according to the pilot strength.

[0058] Specifically, the pilot strength of the LoRa is determined according to the preamble in the LoRa data packet, and the target spreading factor is determined according to the pilot strength. The pilot strength is divided into several levels according to the pilot strength threshold. If the level of the pilot strength is the lowest level, the same spreading factor as the lowest level is selected as the target spreading factor. The spreading factor is used to adjust the transmission rate and the receiving sensitivity of the LoRa mobile terminal, and the greater the value of the spreading factor, the smaller the transmission rate, and the value of the spreading factor ranges from 1 to 12.

[0059] S103: transmitting the device data to the gateway in the target time region corresponding to the target spreading factor according to the target spreading factor, so that the server receives the device data through the gateway, and determines the position information of the LoRa mobile terminal according to the device data.

[0060] Specifically, the gateway divides the time axis into different time regions according to different spreading factors, and each time region corresponds to a spreading factor. According to the target spreading factor selected by the LoRa mobile terminal, the corresponding target time region is searched on the time axis, and the device data is sent to the gateway according to the target spreading factor in the target time region, so as to establish a communication connection with the gateway and the server, wherein the device data is the identity data pre-allocated to the LoRa mobile terminal by the gateway, and the server determines the position information of the LoRa mobile terminal according to the identity data.

[0061] In one embodiment, before step S101, it includes:

[0062] S104: selecting the maximum spreading factor in the preset spreading factor threshold range as the initial spreading factor;

[0063] S105: receiving the LoRa data packet according to the rate corresponding to the initial spreading factor.

[0064] Specifically, the LoRa mobile terminal selects the maximum spreading factor in the preset spreading factor threshold range as the initial spreading factor before receiving the LoRa data source, and synchronizes according to the initial spreading factor. Wherein, the preset spreading factor threshold range is 1-12, and the preferred spreading factor is 12 as the initial spreading factor. The LoRa mobile terminal receives the LoRa data packet according to the transmission rate corresponding to the initial spreading factor.

[0065] In one embodiment, as shown in Figure 2 , step S102 includes:

[0066] S1021: determining the corresponding pilot strength level according to the pilot strength;

[0067] S1022: searching for the corresponding spreading factor in the preset spreading factor threshold range as the target spreading factor according to the pilot strength level.

[0068] Specifically, the LoRa mobile terminal determines the pilot strength level according to the received pilot strength, i.e. the signal strength of the preamble in the LoRa data packet. The pilot strength can be divided into 1-12 levels. The greater the pilot strength, the lower the corresponding level. If the pilot strength is the smallest, the corresponding pilot strength level is the maximum 12. Then the target spreading factor 12 same as the pilot strength level is determined according to the pilot strength level 12.

[0069] In one embodiment, as shown in Figure 3 , step S103 includes:

[0070] S1031: searching a target time region corresponding to the target spreading factor on a time axis; wherein the time region is divided by the gateway according to a preset time threshold value on the time axis, and the time region corresponds to a preset spreading factor threshold value;

[0071] S1032: sending the identity data to the gateway based on the target spreading factor in the target time region.

[0072] Specifically, the gateway can divide the time axis according to equal time periods or unequal time periods. When the time axis is divided according to equal time periods, a time period preset value, such as 20 seconds, is set, the time axis is divided according to the time period preset value, and the time region corresponds to a preset spreading factor. When the time axis is divided according to unequal time periods, three preset values, such as 10 seconds, 20 seconds, and 30 seconds, are set, the time axis is divided according to the distribution of the LoRa terminal device corresponding to the spreading factor, the region of 10 seconds is selected for the spreading factor without corresponding LoRa mobile terminal, the region of 20 seconds is selected for one to two corresponding LoRa mobile terminal spreading factors, the region of 30 seconds is selected for two or more corresponding LoRa mobile terminal spreading factors, and the time region corresponds to a preset spreading factor.

[0073] The LoRa mobile terminal selects a target time region corresponding to the target spreading factor according to the target spreading factor, and sends device data to the gateway in the target time region, wherein the device data includes the identity data of the LoRa mobile terminal.

[0074] In one embodiment, step S1032 includes:

[0075] S10321: determining whether the channel for sending the identity data is occupied;

[0076] S10322: if the channel is not occupied, sending the identity data to the gateway;

[0077] S10323: if the channel is occupied, determining whether the maximum number of competitions of the channel is equal to a preset value;

[0078] S10324: if the maximum number of competitions is equal to the preset value, terminating the sending of the identity data to the gateway;

[0079] S10325: if the maximum number of competitions is less than the preset value, returning to execute the step of sending the identity data to the gateway based on the target spreading factor in the target time region and the subsequent steps.

[0080] Specifically, the LoRa mobile terminal detects whether the channel for transmitting identity data is occupied. If the detection result shows that the channel is not occupied, the identity data is transmitted to the gateway. If the detection result shows that the channel is occupied, it is determined whether the maximum number of competitions of the channel reaches a preset value, and the maximum number of competitions is generally set to 24. If the maximum number of competitions is 24, the transmission of the identity data to the gateway is stopped, and the data transmission is terminated. If the maximum number of competitions is less than 24, the step of transmitting the identity data to the gateway based on the target spreading factor in the target time region and the subsequent steps are returned to be executed.

[0081] The application first receives a LoRa data packet transmitted by a preset LoRa source, then determines the pilot strength of the LoRa data packet, and determines the target spreading factor according to the pilot strength. Finally, the device data is transmitted to the gateway in the target time region corresponding to the target spreading factor according to the target spreading factor, so that the server receives the device data through the gateway, and determines the position information of the LoRa mobile terminal according to the device data. In this method, the LoRa mobile terminal obtains the LoRa data packet from the LoRa source, thereby determining the target spreading factor. The device data is transmitted to the gateway and the server based on the target spreading factor and the corresponding target time region, so as to establish a communication connection between the server and the LoRa mobile terminal, so that the server quickly obtains the position information of the mobile terminal, and realizes the communication connection between the LoRa mobile terminal and the gateway and the server.

[0082] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution. The execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the application.
