Description

Technical Field

[0001] The present application relates to the field of satellite communications, and in particular, to a beam-hopping access method, device, electronic device and non-volatile storage medium. Background Art

[0002] Medium and high-orbit satellites have high orbital altitudes and are far from the earth. When used for communication, they cause large transmission losses and low downlink signal-to-noise ratios. Especially when used for low-frequency handheld terminals or mobile phones for direct communication applications, the uplink signal attenuates greatly when it reaches the medium and high-orbit satellites because the terminal's transmission power and antenna gain are limited, resulting in an extremely low signal-to-noise ratio, making it almost impossible to establish a communication link. In particular, for the Narrow Beam New Radio-Non-Terrestrial Networks (NR-NTN) technology, the UE's minimum uplink and downlink scheduling working bandwidth is 2PRB. Calculated based on a 15kHz subcarrier, a bandwidth of 360kHz is required, which further exacerbates the difficulty of using NR-NTN technology for direct communication between handheld terminals or mobile phones and high-orbit satellites.

[0003] At present, high-orbit synchronous communication satellites generally use fixed multi-beam antennas, with hundreds or thousands of beams covering the target area below the satellite and providing services to the area. This design allows each beam to have a higher gain, but it will evenly distribute the satellite's power among multiple beams. However, the distribution of users on the ground is not evenly distributed among these thousands of beams. Especially when some disasters occur, only the area covered by a certain beam has a large number of access service needs, while there are almost no users in other beams who need services, which greatly wastes the communication resources of the entire satellite. Therefore, the fixed multi-beam antenna design makes it impossible to flexibly configure satellite resources, affecting the communication throughput of the entire satellite.

[0004] Beam hopping is based on phased array antenna technology and uses beam synthesis technology. It can flexibly adjust the direction of the beam, change it over time, and enhance the gain of a single beam. Through beam scheduling, the satellite's power and communication resources can be more flexibly and effectively scheduled and utilized, which can improve the utilization rate of the system. However, when the user accesses the network, the network side equipment does not know the user's location, making the user access efficiency extremely low, and even causing the user to be unable to access for a long time.

[0005] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0032] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0033] High-orbit satellite: It is generally believed that a satellite with an orbit altitude greater than 20,000 kilometers is called a high-orbit earth satellite.

[0034] Medium Earth Orbit Satellite: The orbit of a medium earth orbit satellite MEO is generally between about 2000-30000 kilometers from the ground.

[0035] Beam hopping: The antenna uses phased array technology to achieve digital beam synthesis. The antenna beam can access services in different spatial locations at different times as needed, and has the ability to hop access between multiple spatial locations.

[0036] Fixed beam: The antenna beam is fixedly pointed at a certain direction in space.

[0037] Beam staring: The satellite antenna points to a certain location on the ground. When the satellite moves quickly, the location area where the beam points to the ground remains basically unchanged, which is called beam staring.

[0038] Beam position: The area on the ground where the beam points, or multiple areas on the ground divided according to rules, used for beam pointing and access.

[0039] Narrowband Internet of Things (NB-IoT) is a low-power, wide-area network communication technology designed specifically for IoT devices.

[0040] Narrow Beam New Radio-Non-Terrestrial Networks (NR-NTN): Narrow beams are used to enhance the coverage and performance of satellite communications, especially in non-terrestrial network environments such as low-orbit satellite communications.

[0041] In the related art, beam hopping is based on phased array antenna technology and uses beam synthesis technology. It can flexibly adjust the direction of the beam, change it over time, and enhance the gain of a single beam. Through beam scheduling, the power and communication resources of the satellite can be more flexibly and effectively scheduled and utilized, which can improve the utilization rate of the system. However, when the user accesses, the network side device does not know the user's location, making the user access efficiency extremely low, and even causing the user to be unable to access for a long time. Therefore, there is a problem in the beam hopping access method in the related art that the network side device does not know the user's location, making the user access efficiency extremely low, and even causing the user to be unable to access for a long time. In order to solve this problem, a relevant solution is provided in the embodiment of the present application, which is described in detail below.

[0042] According to an embodiment of the present application, a method embodiment of a beam hopping access method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0043] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Figure 1 FIG. 1 shows a hardware structure block diagram of a computer terminal for implementing a beam hopping access method. Figure 1 As shown, the computer terminal 10 may include one or more (102a, 102b, ..., 102n are used to illustrate) processors 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission module 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of the BUS bus), a network interface, a power supply and / or a camera. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above electronic device. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0044] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuits". The data processing circuits may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. In addition, the data processing circuit may be a single independent processing module, or may be incorporated in whole or in part into any of the other components in the computer terminal 10. As described in the embodiments of the present application, the data processing circuit acts as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0045] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the beam hopping access method in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, the above-mentioned beam hopping access method is realized. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the computer terminal 10 via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0046] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the computer terminal 10. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0047] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 .

[0048] In the above operating environment, the embodiment of the present application provides a flowchart of a beam hopping access method, such as Figure 2 As shown, the method comprises the following steps:

[0049] Step S202: The network side device receives location information reported by the user equipment from the wide beam channel, wherein the network side device is configured with a wide beam signal and a narrow beam signal.

[0050] In the technical solution provided in step S202, the wide-beam signal is a signal of a wide-beam channel in the NB-IOT network. When the network-side device configures the wide-beam signal, indication information is defined in the wide-beam network corresponding to the wide-beam signal. The indication information is used to indicate whether an independent wide-beam network accesses the wide-beam network or whether the wide-beam network guides the narrow-beam network corresponding to the narrow-beam signal to access the wide-beam network.

[0051] There are many ways to define indication information in a wide beam network corresponding to a wide beam signal. For example, the indication information can be defined in the wide beam network corresponding to the wide beam signal in the following ways: defining a first parameter in the master information block information (Master Information Block, referred to as MIB) to represent the indication information, and when the first parameter is 0 or a null value, it indicates that the wide beam network is used for an independent wide beam network (for example, an NB-IoT network), and when the first parameter is 1, it indicates that the wide beam network is used to guide the narrow beam network corresponding to the narrow beam signal (for example, an NR-NTN network) to access; or defining a second parameter in the system information block (System Information Block, referred to as SIB) information to represent the indication information, and when there is no second parameter, it indicates that the wide beam network is used for an independent wide beam network, and when the second parameter is 1, it indicates that the wide beam network is used to guide the narrow beam network corresponding to the narrow beam signal to access; or defining a second parameter in the radio resource control signaling (Radio Resource Control Signaling). A third parameter is defined in the NR-NTN downlink search mode to indicate the indication information. When the value of the third parameter is 1, it indicates that the wide-beam network is used to guide the narrow-beam network corresponding to the narrow-beam signal to access (for example, when the terminal receives the parameter and the value is "1", it reports the terminal location and then enters the NR-NTN downlink search mode to search for an accessible network).

[0052] Step S204: The network side device adjusts the direction of the service beam of the narrow beam signal according to the location information, wherein the adjusted service beam points to the user equipment (eg, the UE on the terminal side).

[0053] In the technical solution provided in step S204, after the network side device configures the wide beam signal (for example, the NB-IoT wide beam signal), the network side device sends the NB-IoT downlink synchronization signal and other information to the terminal side, detects the uplink NB-IoT access signal, receives the location information reported by the terminal side from the NB-IoT channel, and calls the service beam (for example, NR-NTN hopping beam) of the narrow beam signal (for example, NR-NTN signal), and adjusts the direction of the service beam (for example, NR-NTN hopping beam) of the narrow beam signal (for example, NR-NTN signal) so that it points to the user equipment corresponding to the location information reported by the terminal side.

[0054] Step S206: The network side device provides access service to the user equipment based on the service beam of the narrow beam signal.

[0055] In the technical solution provided in step S206, after the network side device configures the narrow beam signal (for example, the NR-NTN signal), the network side device sends the NR-NTN downlink synchronization signal and other information to the terminal side, and detects the uplink NR-NTN access signal, and the receiving terminal (ie, the user equipment) accesses, and the service beam (for example, the NR-NTN hopping beam) of the narrow beam signal (for example, the NR-NTN signal) provides access service for the user equipment.

[0056] After the network-side device directs the service beam of the available narrow beam signal toward the user equipment, it updates the beam scheduling strategy.

[0057] Through the above steps, the access problem in the case of satellite communication beam hopping can be solved. NB-IoT technology is used to report the position, which makes full use of the advantage of the technology's small requirements for uplink and downlink bandwidth. It can reduce the gain of the satellite antenna and simplify the antenna (network) design for initial access. The service beam adopts NR-NTN technology, which can make full use of the power of the service beam and the antenna (network) gain to provide better services for user equipment (UE). It can also take into account the services of user equipment (UE) on multiple beam positions through the rapid hopping of the service beam.

[0058] In the following embodiments of the present application, a flowchart of another beam hopping access method is also provided, such as Figure 3 As shown:

[0059] Step S302: The user equipment on the terminal side searches for a narrow beam signal and determines whether the user equipment is within a serving beam of the narrow beam signal.

[0060] Step S304: When the user equipment is not in the service beam of the narrow beam signal, it searches for the wide beam signal and reports the location information to the network side device through the wide beam channel of the wide beam signal.

[0061] In the technical solution provided in step S304, when the user equipment is in the serving beam of the narrow beam signal, the user equipment performs access in the serving beam.

[0062] It should be noted that the above-mentioned location information can be indicated in the following ways: using the complete global navigation satellite system data of the user device to indicate the location information; or using a preset ratio of the diameter of the satellite beam projected on the ground as a benchmark, as the quantization accuracy of the global navigation satellite system data of the user device, processing the location information, and reporting the processed location information; or dividing the surface of the earth into equal-sized location areas according to preset rules, and numbering the location areas to obtain a location index; the user device determines the target location area where the user device is located based on a pre-established area division table and the global navigation satellite system data of the user device, and indicates the location information with the numbered location index corresponding to the target location area; or using the longitude and latitude information of the area where the user device is located to indicate the location information.

[0063] The following are some specific examples of indicating location information:

[0064] Example 1:

[0065] The UE's Global Navigation Satellite System Data (GNSS data) is used to indicate location information:

[0066] Precise indication: Positioning accuracy is meters, indicated with complete GNSS information.

[0067] Rough indication: Based on 1 / 3 of the diameter of the satellite beam projected on the ground as the quantization accuracy of the UE's GNSS data, the GNSS data is processed and the processed GNSS position data information is reported.

[0068] Example 2:

[0069] The location information is indicated by the location index of the area where the UE is located: the surface of the earth is divided into location areas of equal size according to rules, and these location areas are numbered. The UE determines the location area it is in based on the pre-bound area division table and its own GNSS information, and uses the number index of the area (that is, the above-mentioned target location area) (that is, the numbered location index corresponding to the above-mentioned target location area) to indicate the UE location.

[0070] For example, the world is divided into 1024 location areas, and a 10-bit index is used to represent the number of the location area, and the number of the area where the UE is located is reported each time to indicate the UE location.

[0071] Example 3: Longitude and latitude indication: UE indicates its location using the longitude and latitude information of its area:

[0072] Precise indication: The quantization accuracy is 0.1°; "0" indicates east longitude, "1" indicates west longitude, and the other 11 bits indicate the longitude value; "0" indicates north latitude, "1" indicates south latitude, and the other 10 bits indicate the latitude value. A total of 23 bits.

[0073] Rough indication: quantization accuracy is 1°; "0" indicates east longitude, "1" indicates west longitude, and the other 8 bits indicate longitude value; "0" indicates north latitude, "1" indicates south latitude, and the other 7 bits indicate latitude value. A total of 17 bits.

[0074] Simple indication: quantization accuracy is 3°; "0" indicates east longitude, "1" indicates west longitude, and the other 6 bits indicate longitude value; "0" indicates north latitude, "1" indicates south latitude, and the other 5 bits indicate latitude value. A total of 13 bits.

[0075] Step S306: The user equipment searches for a narrow beam signal directed to the user equipment by the network side device based on the location information, and accesses the service beam of the narrow beam signal.

[0076] The following is a specific embodiment: the UE (i.e., the above-mentioned user equipment) searches for the downlink NR-NTN signal (i.e., the above-mentioned narrow beam signal) and determines whether the current UE is in the NR-NTN service beam (i.e., the service beam of the above-mentioned narrow beam signal). If it is in the NR-NTN service beam, access can be initiated in the NR-NTN beam; if the current UE determines that it is not in the NR-NTN service beam, it searches for the synchronized NB-IoT signal and initiates an NB-IoT access request. The current UE reports the location information through the NB-IoT channel. After obtaining the location information, the current UE searches for the NR-NTN signal of the NR-NTN service beam (i.e., the narrow beam signal pointed to the user equipment by the above-mentioned network side device based on the location information) and accesses the NR-NTN service beam.

[0077] In the technical solution provided in steps S304-S306, the location information is reported to the network side device through the wide beam channel of the wide beam signal (for example, the NB-IoT channel), and there are multiple implementation methods for the user equipment to search for the narrow beam signal of the network side device pointing to the user equipment based on the location information. For example: the user equipment sends a random access preamble (for example, a random access preamble (Narrowband Physical Random Access Channel, referred to as NPRACH)) and the location information to the network side device in the wide beam channel of the wide beam signal; the user equipment receives a random access response message (for example, a random access response (Random Access Response, referred to as RAR)), wherein the random access response message is used to indicate whether the network side device has received the location information; or the user equipment waits for a preset round-trip time (for example, the round-trip time (Round-Trip Time, referred to as RTT)) and then searches for the narrow beam signal (for example, the NR-NTN downlink synchronization signal) of the network side device pointing to the user equipment based on the location information.

[0078] After receiving the random access response message, the user equipment reports the location information to the network side device through a first message, wherein the first message is a connection request message sent by the uplink resources allocated in the random access response message; the user equipment confirms in a second message whether the network side device has received the location information, wherein the second message is a connection establishment confirmation message returned by the network side device; or, the user equipment waits for a preset round-trip time and then searches for a narrow beam signal directed to the user equipment based on the location information by the network side device, and after reporting the location information to the network side device through a wide beam channel of a wide beam signal, the user equipment confirms in a wireless resource control connection RRC message whether the network side device has received the location information; or, the user equipment starts a timer after reporting the location information, and searches for a narrow beam signal directed to the user equipment based on the location information by the network side device after the timer expires.

[0079] The following are several examples of user equipment on the specific terminal side reporting location information and searching for NR-NTN signals:

[0080] Example 1:

[0081] When the UE (i.e., the above-mentioned user equipment) sends an uplink preamble on the NB-IoT channel (i.e., the wide beam channel of the above-mentioned wide beam signal), it carries the location information after the NPRACH data, that is, the preamble (corresponding to the above-mentioned sending of the random access preamble (for example, the random access preamble (Narrowband Physical Random Access Channel, referred to as NPRACH)) and the location information are reported to the network side device. The UE can confirm whether the network side device has received the location data by retrieving the received RAR message (corresponding to the above-mentioned random access response message). The UE may also not confirm, and after sending the reported preamble + location data, wait for 1 / 2 RTT and directly search for the NR-NTN downlink synchronization signal (corresponding to the above-mentioned user equipment waiting for the preset round-trip time to search for the narrow beam signal of the network side device pointing to the user equipment based on the location information).

[0082] Example 2:

[0083] The UE completes NPRACH transmission and RAR reception in the NB-IoT channel, and then carries the location information in Msg3 (corresponding to the above-mentioned first message) to report to the network side device. The UE can confirm whether the network side device has received the location information in Msg4 (corresponding to the above-mentioned second message), and then wait for NR-NTN beam access. The UE can also wait for 1 / 2 RTT (corresponding to the above-mentioned preset round-trip time) without Msg4 message confirmation after sending Msg3, and directly search for NR-NTN downlink synchronization signals (corresponding to the above-mentioned search for the narrow beam signal of the network side device pointing to the user equipment based on the location information), wherein Msg3 corresponds to the message for interaction in the third step of the four-step random access, the connection request message sent by the uplink resource, Msg4 corresponds to the message for interaction in the fourth step of the four-step random access, and the connection establishment confirmation message returned by the network side device. The four-step random access process is as follows:

[0084] 1. Random access request: The UE first sends a random access request (RAR) to the network. This request contains the UE's identity information and access reason. The UE will randomly select a PRACH (Physical Random Access Channel) resource to send the RAR.

[0085] 2. Random access response: After receiving the RAR from the UE, the network device will send a random access response (RAR) to the UE. The RAR contains the uplink resources allocated to the UE, time adjustment information, temporary UE identification, etc.

[0086] 3. Connection Request: The UE uses the uplink resources allocated in the RAR to send a connection request, which contains the complete identity information of the UE, service requirements, etc.

[0087] 4. Connection establishment: After receiving the connection request from the UE, the network side device will perform corresponding processing, such as identity authentication, resource allocation, etc. If the verification is successful, the network side device sends a connection establishment confirmation (Connection Establishment Accept) to the UE, indicating that the UE has successfully accessed the network. If there is a problem, the network side device will send a connection establishment reject (Connection Establish Reject).

[0088] Example 3:

[0089] The UE completes 4 steps of random access and authentication in the NB-IoT channel, and then reports the UE location to the network device through the RRC message. The UE can confirm in the RRC message whether the network device has received the location information, and confirm the scheduling information of the NR-NTN service beam given by the network device, and then wait for the access service of the NR-NTN beam according to the scheduling information. The UE can also start a timer after reporting the location information without RRC message confirmation. After the timer ends, it directly searches for the NR-NTN downlink synchronization signal (corresponding to the above-mentioned search for the narrow beam signal of the network device pointing to the user equipment based on the location information).

[0090] In the following embodiments of the present application, a network side flow diagram of a beam hopping access method is also provided, such as Figure 4As shown, after the network side (i.e., the network side device) configures the wide beam signal (e.g., the NB-IoT wide beam signal), the network side (i.e., the network side device) sends the NB-IoT downlink synchronization signal and other information to the terminal side, detects the uplink NB-IoT access signal, receives the location information reported by the terminal side from the NB-IoT channel, and calls the service beam (e.g., NR-NTN hopping beam) of the narrow beam signal (e.g., NR-NTN signal), adjusts the direction of the service beam (e.g., NR-NTN hopping beam) of the narrow beam signal (e.g., NR-NTN signal) to point to the user equipment corresponding to the location information reported by the terminal side, and sends the NR-NTN downlink signal. The network side (i.e., the network side device) sends information such as the downlink synchronization signal of NR-NTN to the terminal side, detects the uplink NR-NTN access signal, and the receiving terminal (i.e., the user equipment) accesses, and the service beam (e.g., the NR-NTN hopping beam) of the narrow beam signal (e.g., the NR-NTN signal) provides access service; after the network side (i.e., the network side device) configures the narrow beam signal (e.g., the NR-NTN signal), the network side (i.e., the network side device) sends information such as the downlink synchronization signal of NR-NTN to the terminal side, detects the uplink NR-NTN access signal, and the receiving terminal (i.e., the user equipment) accesses, and the service beam (e.g., the NR-NTN hopping beam) of the narrow beam signal (e.g., the NR-NTN signal) provides access service.

[0091] In the following embodiments of the present application, a terminal side flow diagram of a beam hopping access method is also provided, such as Figure 5 As shown, the terminal (i.e., UE, the above-mentioned user equipment) detects the NR-NTN downlink synchronization signal (i.e., the above-mentioned narrow beam signal) and determines whether it is synchronized (i.e., determines whether the current UE is in the NR-NTN service beam (i.e., the service beam of the above-mentioned narrow beam signal)). If it is synchronized (i.e., the UE is in the NR-NTN service beam), access can be initiated in the service beam (i.e., the above-mentioned NR-NTN service beam). If the access is successful, the terminal side performs authentication and authentication in the service beam (i.e., the above-mentioned NR-NTN service beam) and accepts the service. If the access is unsuccessful, the NR-NTN downlink synchronization signal is re-detected; if the current UE is not synchronized (i.e., it is determined that it is not in the NR-NTN service beam), the NB-IoT downlink synchronization signal is detected, and it is determined whether it is synchronized. If it is synchronized, the terminal initiates an access request in the NB-IoT beam, and the current UE reports the location information through the NB-IoT channel. After obtaining the location information, the NR-NTN downlink synchronization signal is re-detected to complete the access.
