Description

Technical Field

[0001] This application relates to wireless communication technology, specifically to an anchored cooperative data transmission method and system based on a non-cellular network. Background Technology

[0002] Mobile communication requires a large amount of continuous spectrum resources for high-speed data transmission. Current mobile networks have already extended wireless frequency bands to millimeter waves and terahertz. Therefore, traditional spectrum resources are extremely scarce, and it will be difficult to develop new wireless microwave frequency bands in the future evolution of wireless technology. Thus, how to efficiently utilize existing non-renewable spectrum resources has become a key issue that the industry needs to consider.

[0003] The interconnection of information across air, space, land, and sea forms the basic physical form of next-generation mobile networks. However, this does not mean that radio frequency signals will cover all areas of the globe, which is both energy-intensive and unnecessary. Due to the increasing scarcity of non-renewable wireless spectrum resources, wireless transmission signals are constantly seeking more frequency bands for modulation, inevitably leading to increased energy consumption from the growing number of base stations. In reality, the physical space for human activity is ultimately limited. For vast, sparsely populated oceans and deserts, it is difficult to build base stations on a large scale; covering too many radio frequency resources is uneconomical and does not align with global carbon emission reduction requirements and objectives.

[0004] To efficiently utilize spectrum resources, in addition to employing existing physical layer multiplexing technologies such as frequency division, time division, and space division, certain considerations and innovations are also needed at the network architecture level (L3) to achieve ubiquitous network services in next-generation wireless networks. "Ubiquitous services" does not mean "ubiquitous signals," nor does it mean that data transmission signals are constantly present in the 2 billion cubic kilometers of Earth's biosphere. Rather, it means that network services can maintain a stable presence in spaces where humans (or terminals) are active. Summary of the Invention

[0005] This application provides an anchored collaborative data transmission method and system based on non-cellular networks, which efficiently utilizes existing non-renewable spectrum resources to provide network services to vast, sparsely populated oceans and deserts.

[0006] Firstly, a method for anchored cooperative data transmission based on a non-cellular network is provided, including the following steps:

[0007] S1. When a user terminal enters the range of an anchor base station, it updates its location information to the anchor base station every preset time after registration.

[0008] S2. The anchor base station sends the user terminal location information to the nearest directional transmission base station;

[0009] S3. The directional transmission base station performs high-power wireless radiation to the area where the user terminal is located until the user terminal leaves the radiation area of ​​the directional transmission base station, at which point the directional transmission base station releases the occupied wireless spectrum resources.

[0010] In some embodiments, the method further includes:

[0011] S4. The anchor base station sends the location of the user terminal to the nearest anchor base station for continued positioning. The nearest anchor base station repeats steps S1-S4.

[0012] In some embodiments, in step S1, the user terminal sends a registration message to the anchor base station, and after the anchor base station replies with a response message, the user terminal begins to send location information to the anchor base station.

[0013] In some embodiments, the location information includes the coordinates of the user terminal, and the anchor base station tracks the location of the user terminal via radio frequency beams.

[0014] In some embodiments, the user terminal locates its coordinates using BeiDou or GPS.

[0015] In some embodiments, in step S2, the anchor base station activates the nearest directional transmission base station and sends the user terminal's own messages and location information to that directional transmission base station.

[0016] In some embodiments, in step S3, after the user terminal and the directional transmission base station handshake, the directional transmission base station adjusts the azimuth and elevation angles of the radio frequency antenna array according to the location information of the terminal, and performs high-power wireless radiation to the area where the user terminal is located.

[0017] In some embodiments, if the anchor base station does not receive location information from the user terminal within a preset time, it sends an inquiry message to the user terminal. If no response is received, it is determined that the user terminal has left the radiation area of ​​the directional transmission base station.

[0018] In some embodiments, the anchor base station sends a no-response message from the user terminal to the directional transmission base station, which then releases the connection and the occupied radio spectrum resources.

[0019] Secondly, a cellular-free anchored cooperative data transmission system is provided, comprising:

[0020] Anchor base stations are used to receive the location information of user terminals at preset intervals after the user terminal enters its range and registers. They are also used to send the location information of user terminals to nearby directional transmission base stations.

[0021] A directional transmission base station is used to radiate high-power wireless signals to the area where a user terminal is located until the user terminal leaves the radiation area of ​​the directional transmission base station, thus releasing the occupied wireless spectrum resources.

[0022] The beneficial effects of the technical solution provided in this application include:

[0023] When a user terminal enters the range of an anchor base station, it updates its location information to the anchor base station. The anchor base station then sends the user terminal's location information to a nearby directional transmission base station. The directional transmission base station then performs high-power wireless radiation to the area where the user terminal is located. Once the user terminal leaves the radiation area of ​​the directional transmission base station, the occupied wireless spectrum resources are released. Wireless resources in the same frequency band can be dynamically allocated in different areas, saving spectrum and making efficient use of spectrum resources.

[0024] After a user terminal leaves the radiation area of ​​a directional transmission base station, the corresponding anchor base station sends the user terminal's location to a nearby anchor base station for continued positioning. The nearby anchor base station repeats the above method to achieve wide-area wireless coverage in sparsely populated areas (such as oceans and deserts). This not only makes efficient use of existing non-renewable spectrum resources but also saves energy and investment, meeting the requirements and objectives of global carbon emission reduction.

[0025] In wireless cellular network architecture, making full use of a combination of low-power positioning coverage and high-power directional illumination for mobile communication may be the trend for the development of the next generation of green networks. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] like Figure 1 As shown, this application provides an embodiment of an anchored cooperative data transmission method based on a non-cellular network, which can solve the problem of providing network services to vast, sparsely populated oceans and deserts. This embodiment includes the following steps:

[0032] S1. When the user terminal enters the range of the anchor base station, it updates its location information to the anchor base station every preset time after registration.

[0033] S2. The anchor base station sends the user terminal location information to the nearest directional transmission base station.

[0034] S3. The directional transmission base station performs high-power wireless radiation to the area where the user terminal is located until the user terminal leaves the radiation area of ​​the directional transmission base station, thus releasing the occupied wireless spectrum resources.

[0035] Furthermore, the above methods may also include:

[0036] S4. The anchor base station sends the location of the user terminal to the nearest anchor base station for continued positioning. The nearest anchor base station repeats steps S1-S4.

[0037] like Figure 2 As shown, the anchor base station in this embodiment can use smart beamforming technology to track and locate the user terminal. In step S1 above, when the user terminal enters the range of the anchor base station, the user terminal sends a registration message to the anchor base station. After the anchor base station replies with a response message, the user terminal begins to send location information to the anchor base station every preset time interval. Preferably, the preset time interval can be 5 seconds.

[0038] It is understandable that the aforementioned location information includes the coordinates of the user terminal, which can be obtained through BeiDou or GPS, or other positioning systems. Obtaining coordinates through positioning systems enables the anchor base station to always obtain the precise location of the user terminal and track the user terminal's location through radio frequency beams until the user terminal leaves the coverage area of ​​the directional transmission base station.

[0039] In step S2 above, after the anchor base station obtains the location information of the user terminal, it activates the nearest directional transmission base station and sends the user terminal's identity information and location information to the directional transmission base station.

[0040] In step S3 above, after the user terminal and the directional transmission base station handshake, the directional transmission base station adjusts the azimuth and elevation angles of the radio frequency antenna array according to the terminal's location information (e.g., ...). Figure 2 As shown, it provides high-power wireless radiation to the area where the user terminal is located, providing high-speed data transmission services.

[0041] If the anchor base station does not receive location information from the user terminal within a preset time (e.g., 5 seconds), it sends an inquiry message to the user terminal. If no response is received, it determines that the user terminal has left the radiation area of ​​the directional transmission base station. The anchor base station then sends a no-response message to the directional transmission base station, which stops transmitting data and releases the connection and the occupied radio spectrum resources.

[0042] In step S4 above, after the user terminal leaves the radiation area of ​​the directional transmission base station, the aforementioned anchor base station sends the location of the user terminal to the neighboring anchor base station for continued positioning. The neighboring anchor base station repeats steps S1-S4 to realize the data transmission process in the radiation area of ​​the next directional transmission base station.

[0043] This application also provides an embodiment of an anchored cooperative data transmission system based on a non-cellular network, which can be used to implement the above method. The system includes an anchor base station and a directional transmission base station. The anchor base station is used to receive the location information of the user terminal at preset time intervals after the user terminal enters its range and registers; the anchor base station is also used to send the user terminal's location information to nearby directional transmission base stations. The directional transmission base station is used to perform high-power wireless radiation into the area where the user terminal is located until the user terminal leaves the radiation area of ​​the directional transmission base station, releasing the occupied wireless spectrum resources.

[0044] like Figure 3 As shown, this application also provides an embodiment of an anchored cooperative data transmission signaling process, which can be based on the above method and system. The specific process is as follows:

[0045] A1. When the user terminal enters the range of the anchor base station, it sends a registration message (REGISTER_REQUEST) to the anchor base station. The REGISTER_REQUEST contains relevant information about the user terminal (UE) and attempts to obtain a connection.

[0046] A2. The anchor base station returns a response message (PAGING_RESPONSE) to the user terminal.

[0047] A3. The user terminal sends its location information (LOCATION_INFO) to the anchor base station. The location information is the positioning coordinates from Beidou or GPS. Then, it sends LOCATION_INFO to the anchor base station once every 5 seconds.

[0048] A4. The anchor base station sends the user terminal information to the nearest directional transmission base station, specifically sending the user terminal's own message (UE_REGISTER_INFO) and location information (UE_LOCATION_INFO).

[0049] A5. After the user terminal and the directional transmission base station handshake, the directional transmission base station sends high-power wireless radiation for high-speed data transmission. The signaling process for data transmission is the same as in traditional networks and will not be described in detail here.

[0050] A6. If the anchor base station does not receive a LOCATION_INFO from the user terminal within 5 seconds, the anchor base station sends a query message (KEEPALIVE_REQUEST) to the user terminal. If no response is received, it means that the user terminal has left the wireless coverage area.

[0051] A7. The anchor base station sends a no-response message (UE_NORESPONSE) to the directional transmission base station, informing the user terminal that it has left the radiation area of ​​the directional transmission base station.

[0052] A8. The directional transmission base station releases the connection and the occupied radio spectrum resources, and sends the signaling RELEASE_RESOURCE to the anchor base station.
