Technical Field

[0001] The present application relates to the technical field of the allocation of communication resources such as wireless frequency points, and particularly relates to a method for communication based on coordinates and a matching look-up table. Background Art

[0002] Existing device communication terminals establish a communication connection with a communication base station. Usually, they conduct communication connection inquiries through multiple shared frequency points between the device communication terminal and the communication base station, and select a suitable channel based on signal quality and busy / idle status until a communication connection is established at a certain frequency point, and then start subsequent information data transmission; this process requires inquiry interactions or attempts at multiple frequency points, and there are a series of deficiencies such as low efficiency in the allocation of communication frequency point resources, multiple terminals simultaneously occupying shared channels, terminals being unable to actively obtain and select frequency points, and a large number of steps, excessive time, and high power consumption in establishing a communication connection between devices.

[0003] Therefore, for mobile device communication or battery-powered Internet of Things terminals to establish a communication connection with a communication base station, more effective methods and strategies are needed to achieve rapid matching of frequency points, reduce the steps of establishing a connection, shorten the time for establishing a communication connection, and improve the battery life of mobile terminals.

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0014] The purpose of the present application is to provide a method for communication based on coordinates and a matching look-up table, aiming to improve the communication connection efficiency and reliability of communication terminals with coordinate information.

[0015] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] In an exemplary embodiment, as Figure 1 shown, the method for communication based on coordinates and a matching look-up table in this embodiment is implemented based on a device communication terminal and a communication base station. The method for communication based on coordinates and a matching look-up table includes steps 1 to 3.

[0017] Step 1: The communication terminal obtains the coordinates of its location and a preset matching look-up table; the preset matching look-up table includes a plurality of matching groups; each matching group includes: a regional address and communication resources; the regional address is a set of multiple coordinates.

[0018] As an optional implementation manner, the communication resources include: communication frequency band, communication frequency point, communication channel, communication bandwidth, radio transceiver power, permitted access terminal ID, base station information, communication protocol, and communication mode.

[0019] Among them, before step 1, a method for communication based on coordinates and a matching look-up table in the present application further includes: determining the preset matching look-up table by means of pre-configuration or online update.

[0020] Specifically, the communication resources corresponding to different regional addresses may be the same or different.

[0021] Step 2: Match the coordinates of the communication terminal with the regional address in the preset matching look-up table to determine the regional address that contains the coordinates of the communication terminal.

[0022] Step 3: Determine the communication resources included in the matching group corresponding to the successfully matched regional address as available resources, complete the allocation and access preparation of the available resources, and communicate the communication terminal with the base station using the available resources.

[0023] As an optional implementation manner, before determining the communication resources included in the matching group corresponding to the successfully matched regional address as available resources, completing the allocation and access preparation of the available resources, and communicating the communication terminal with the base station using the available resources, the method for communication based on coordinates and a matching look-up table further includes: determining the communication resources used by each base station.

[0024] Determining the communication resources used by each base station specifically includes: For any base station, the base station obtains the coordinates of its own location and a preset matching comparison table. Match the coordinates of the base station with the area addresses in the preset matching comparison table to determine the area address containing the coordinates of the base station. Determine the communication resources included in the matching group corresponding to the successfully matched area address as the communication resources used by the base station. Or the communication resources used by the base station are the communication resources corresponding to the matching group specifying the base station in the preset matching comparison table.

[0025] As an alternative implementation, communicating with a base station using available resources includes: When the base station information in the matching group where the available resources are located includes multiple base stations, the communication terminal, according to the preset priority order in the base station information in the preset matching comparison table, the base station with the highest priority is the master base station, and the base stations with non-highest priorities are slave base stations, and uses the available resources in the current matching group to connect to the master base station to achieve communication.

[0026] If the connection between the communication terminal and the master base station fails, the communication terminal updates the available resources for communication to the available resources of the current slave base station in sequence through the base station information in the preset priority order, and sequentially connects to the current slave base station using the available resources to achieve communication; the base station information includes: base station serial number and preset priority order; wherein, the available resources of the current slave base station are determined by the base station serial number of the current slave base station or the area address where it serves as the host station.

[0027] As an alternative implementation, step 3 specifically includes: 1) Determine the communication resources included in the matching group corresponding to the successfully matched area address as available resources, and complete the allocation and access preparation of the available resources; wherein, the acquisition method of the base station area location is through self-update or prior designation. 2) Based on the area location of the base station using the available resources, enable the communication terminal to communicate with the base station using the available resources.

[0028] This application pre-allocates communication resources for a specified area according to the area in advance, and uses a preset matching comparison table for communication between the base station and the communication terminal, reducing the time and power consumption for the communication terminal to establish a connection, extending the battery life, and improving the allocation efficiency and redundancy of radio frequency resources, and reducing communication resource conflicts.

[0029] In an exemplary embodiment, the communication terminal is specifically a vehicle-mounted communication terminal. In an intelligent transportation system, the vehicle-mounted communication terminal needs to move between different road sections, and the communication environments and resource requirements of different road sections are also different. Using the method of this application, in urban congested road sections, higher-bandwidth communication resources are allocated to ensure real-time transmission of traffic information and communication between vehicles, and to ensure traffic safety and the efficient operation of the traffic management system.

[0030] In an exemplary embodiment, in large event venues, such as stadiums and concert sites, the communication demands of these venues usually peak within a short period. By the method of the present application, a stadium or concert site can be divided into multiple regional addresses, each corresponding to different communication resources, avoiding network congestion caused by a large number of users concentrating on using the same communication resources, so as to achieve load balancing.

[0031] In an exemplary embodiment, in an industrial park, a large number of Internet of Things terminals such as fixedly installed instruments and meters and movable positioning devices urgently need to improve communication efficiency to reduce communication duration and energy consumption. The Internet of Things terminals are all communication terminals in the present application. As Figure 2 shown, by using the method of the present application, the industrial park is divided into several regions, that is, regions 1, 2, and 3 divided by dotted lines are delineated within the park boundary D, and exclusive communication resources are configured for each region. Such as Figure 2 base stations S1, S2, and S3 in the figure. The frequency band of base station S1 is 433M, the frequency band of base station S2 is 470M, and the frequency band of base station S3 is 475M. Fixed instruments are set in region 2. The signal coverage of base station S1 is circle C1 centered on base station S1, the signal coverage of base station S2 is circle C2 centered on base station S2, and the signal coverage of base station S3 is circle C3 centered on base station S3. Circles C1, C2, and C3 constitute the signal coverage range. The terminal device can quickly and accurately find the corresponding communication resources through the matching look-up table of its own position coordinates and communication resources, excluding the base stations in other regions and the overlapping frequency bands, and then transmit the device operation status information in a timely manner, effectively shortening the communication duration and reducing energy consumption. For example, the movable device M1 communicates with base station S1 through the communication resources of frequency band 433M in region 1, the fixed-position instrument F communicates with base station S2 through the communication resources of frequency band 470M in region 2, and the movable device M2 communicates with base station S3 through the communication resources of frequency band 475M in region 3.

[0032] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0033] Specific examples are used in this article to elaborate on the principles and implementation manners of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present application.
