Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a method and device for communication between user equipment via a network node. Background Art

[0002] Wireless communication refers to the transmission and communication between multiple nodes using radio waves instead of through conductors or cables. Wireless communication can transmit various types of data, such as sound, images, text, video, etc. Wireless communication technology can transmit data over long distances at various locations, and has the advantages of flexible and changeable connection locations, short connection time, and simple connection methods. It is currently widely used in society. At present, the wireless networks required for scientific research and industry can achieve rapid interconnection between multiple users and multiple devices through the latest wireless communication technology, and then achieve rapid interaction of information and data, allowing users or devices to wirelessly transmit various data over long distances, and finally build a wireless communication network. In a wireless communication network, there are various ways to transmit data between devices. The common transmission method is that data is transmitted from user equipment to network nodes such as base stations and then transmitted to user equipment. For this type of wireless communication method, a large number of base stations will be deployed in densely populated areas (such as city centers) to carry short-distance data transmission of a large number of communication devices in a small area; a small number of base stations will be deployed in areas with low population density (such as suburbs) to carry long-distance data transmission of a large number of communication devices in a large area.

[0003] Data transmission related to scientific research and industry, such as the transmission of geological exploration data with large files and precise file content in the field with poor signals, often has large data transmission volume, long transmission time, uncertain transmission environment, and low fault tolerance due to the accuracy of the data content and the complexity of the environment. In the process of transmitting data using the above scheme, the user equipment will be connected to the communication network of a base station for a long time, and the base station will carry the data transmission of a large number of communication devices other than the user equipment for a long time. Some base stations may have a large load, resulting in reduced network speed, slow data transmission speed, and even base station data transmission errors and abnormal status. In addition, due to the different locations and surrounding environments of base stations, the access volume of equipment at the base station is different in a period of time, and there will be peaks and troughs in data transmission. If statistics are taken on a daily, weekly and monthly basis, the transmission peaks and troughs will have certain rules. When a large amount of data is transmitted, the base station with a transmission trough can be selected for data transmission.

[0004] In order to avoid the above problems, it is necessary to design a method for communicating between user devices via network nodes and a device using the method, which can be used to communicate with another user device and transmit data by wirelessly accessing the base station communication network in various environments, and can automatically analyze the base station with the fastest data transmission speed and the lowest error rate, select the base station suitable for access, access the base station network to start transmitting data, monitor the network, transmission and own status of the base station in real time, and reselect the base station to continue transmission when an abnormality occurs in the base station, so as to meet the communication needs of user devices in special scenarios, special fields and special environments.

[0041] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The embodiment of the present invention provides a method for communication between user devices via a network node. The method can be performed by an electronic device with a wireless communication function. In this embodiment, the electronic device is used to transmit geological exploration data, such as geological exploration videos and images with large files and long transmission time. Figure 1 , Figure 2 As shown, the method comprises the following steps:

[0043] Self-check, calculate the maximum transmission time

[0044] Step 1. In this embodiment, the first user device is a handheld communication device, which has stored geological exploration videos and images that need to be transmitted. The first user device first performs a self-check on the device itself and the data transmission system, checks the device status, system status and network transmission function, and avoids subsequent device abnormalities. After the self-check is completed, the first user device calculates the size of the data to be transmitted. Geological exploration video and image files are large, and the transmission time may take one to several hours, so it is necessary to ensure that the state of the user device remains stable during the transmission time. Therefore, a self-check step is added in this embodiment.

[0045] Step 2: The first user equipment calculates the signal strengths of n nearby base stations and the distances between the first user equipment and the n nearby base stations, and locates the first user equipment by using a triangulation positioning method. Figure 1 Only four base stations are shown in FIG. According to the method, the first user equipment will select a base station with fast transmission speed and high transmission quality from the n nearby base stations for connection.

[0046] Step 3: The first user equipment calculates the maximum time to send data to the base station based on the size of the data to be transmitted, the signal strength, and the distance from the base station. This time is the longest time required to transmit the above data among the n base stations. In the subsequent steps, by analyzing the network transmission status of each base station within the longest time, a suitable base station is selected for communication.

[0047] Send a log retrieval request to a nearby base station

[0048] Step 4: The first user equipment sends an identity authentication identifier and a wireless network work log request to n nearby base stations for analyzing the network transmission status of the base stations in the future.

[0049] Step 5: The first user equipment obtains the wireless network work logs of the n nearby base stations within a preset period, where the preset period is several days, weeks or months. The maximum time for sending data to the base station is set to the estimated maximum transmission time, and the base station network data transmission situation within the estimated maximum transmission time is analyzed for each base station within the preset period, starting from the moment of sending the wireless network work log request every day. The base station network data transmission situation includes the number of wireless device accesses, bandwidth occupancy, transmission rate, transmission load, data transmission peak, data transmission valley, and signal strength.

[0050] After the first user equipment obtains the wireless network work log of the base station, it analyzes the log to predict how many wireless devices will access each base station in the future, the occupancy of the base station bandwidth in the future, the average data transmission rate of the base station in the future, and whether there will be a peak in device access and data transmission at the base station in the future. Based on the above data, the average transmission speed of the base station in the future can be estimated.

[0051] Step 6: Based on the analyzed network data transmission conditions of the n base stations and the size of the data to be transmitted, calculate the time required to transmit the data to be transmitted to the n base stations within the estimated longest transmission time from the moment the wireless network work log request is sent, and obtain n estimated transmission times.

[0052] Step 7: sort the calculated n estimated transmission times from shortest to longest, and set the base stations corresponding to the sorted n estimated transmission times as the first base station to the nth base station in sequence. After the first user equipment estimates the transmission time of the base station, it tests the data transmission quality of each base station.

[0053] Step 8: Send test data to the first base station to the nth base station in sequence, and obtain feedback test data from the first base station to the nth base station, detect the network status of the base station according to the test data and the obtained feedback test data, generate a network test report for each base station, and feed back the base station network test report to the n base stations, wherein the base station network test report includes the data transmission bit error rate, delay, data loss rate, signal strength and signal-to-noise ratio of the base station, as well as the location data and network transmission parameters of the first user equipment; this step can not only test the data transmission quality of each base station, but also feed back the test results to the base station, and the base station can adjust the equipment according to the defects exposed in the test results.

[0054] Step 9. Among the base stations whose network conditions meet the transmission requirements, select the base station with the shortest estimated transmission time as the first connected base station, send an identity authentication identifier and a network access request to the first connected base station, and the first user device accesses the network of the first connected base station and starts transmitting the data to be transmitted, and generates a transmission log based on the content of the data to be transmitted and the specific time point; through this step, the first user device selects a base station that can both ensure high quality of data transmission and achieve the fastest data transmission speed, and then accesses the base station network to start data transmission.

[0055] Step 10, the first user equipment obtains base station network feedback information from the first connected base station in real time, the communication feedback information includes the real-time number of wireless device access to the first connected base station, the real-time transmission rate, the real-time transmission load, the real-time signal strength, and the real-time communication bandwidth occupancy rate. The first user equipment analyzes the communication feedback information and generates a first connected base station communication log through the communication feedback information and the corresponding time; in this step, the user equipment monitors the data transmission status of the access base station in real time and generates a corresponding first connected base station communication log. When an abnormality or failure occurs in the first connected base station, the fault can be discovered in time, and the specific time of the failure can be found through the first connected base station communication log to adjust subsequent data transmission.

[0056] Step 11, this step is performed when an abnormality occurs in the base station or user equipment. The first user equipment analyzes the communication feedback information. When the first user equipment finds that the first connected base station network is abnormal, the first user equipment issues an alarm, determines the time point when the base station network is abnormal according to the base station communication log, ends the current data transmission process, disconnects the network connection with the first connected base station, and then executes step 12. This step can realize that the user equipment automatically stops transmitting data, switches base stations, and continues to transmit data when the base station fails. When the first user equipment has an equipment abnormality or data transmission abnormality, the first user equipment issues an alarm, ends the current data transmission process, disconnects the network connection with the first connected base station, repairs the first user equipment, and after returning to normal state, re-sends the identity authentication identifier and network access request to the first connected base station, re-accesses the network of the first connected base station, determines the time point when the data transmission process ends according to the transmission log, starts to transmit the remaining data to be transmitted after the time point when the first user equipment ends the data transmission process, and continues to generate the transmission log. This step can prevent data transmission abnormality caused by the user equipment itself. When the user equipment fails, automatic repair is realized, and subsequent data transmission continues according to the transmission log. If the first user equipment does not find that the first connected base station network is abnormal, and the first user equipment does not have a device abnormality or a data transmission abnormality, step 13 is executed.

[0057] Step 12. Among the base stations whose base station network test data reaches the preset value, select the base station with the second shortest estimated transmission time as the second connected base station, send an identity authentication identifier and a network access request to the second connected base station, and the first user device accesses the network of the second connected base station, and starts transmitting the remaining data to be transmitted after the time point when the abnormality occurs in the first connected base station network, and continues to generate transmission logs.

[0058] Step 13: Complete data transmission from the first user equipment to the base station, and transmit data from the base station to the second user equipment.
