Description

Background Art

[0002] With the development of sixth-generation mobile communication technology (6G) services and users in the future, the spectrum resources of terrestrial communication networks will not be able to meet business needs. In the future, satellite networks and terrestrial communication networks will work together. Therefore, base stations can use satellite spectrum resources to improve the business rate and network capacity in hot spots.

[0003] In related technologies, satellite networks and ground communication networks use different spectrums to avoid interference. When the satellite network is idle, the ground communication network can use the satellite spectrum through cognitive radio technology. However, cognitive radio technology requires the construction of corresponding sensing equipment and continuous detection of whether the satellite spectrum is occupied, which makes the implementation method complicated.

[0069] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0070] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0071] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0072] Figure 1 A schematic diagram showing an exemplary system architecture of a satellite spectrum resource utilization method that can be applied to an embodiment of the present disclosure.

[0073] like Figure 1As shown, the system architecture 100 may include a terminal device, a ground base station 110, a core network 120, a ground gateway 130 and a satellite 140, wherein the core network 120 is used to establish a network connection between the ground base station and the ground gateway 130, and the network may be a wired network or a wireless network.

[0074] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocol. The network is usually the Internet, but it can also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged through the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above data communication technologies.

[0075] The communication system may adopt different communication technologies, such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency-division Multiple Access (OFDMA), Single Carrier FDMA (SC-FDMA), and Carrier Sense Multiple Access with Collision Avoidance. According to the capacity, rate, latency and other factors of different networks, the network can be divided into 2G (generation) network, 3G network, 4G network or future evolution network, such as 5G network, which is referred to as network or system for short. In the present disclosure, the network includes network equipment, which may be, for example, a wireless access network node; the core network includes core network equipment. Among them, the wireless access network node may also be a ground base station 110. Typically, each base station is used to provide network services to cell users within the coverage area. Figure 1 In the figure, three coverage areas are shown, and a ground base station 110 is set in each coverage area. At the same time, the satellite uses beam 1 for communication in coverage area 1; uses beam 2 for communication in coverage area 2; and uses beam 3 for communication in coverage area 3.

[0076] The ground base station 110 can communicate with the core network equipment via wires to provide communication services to the terminal equipment. The core network equipment is, for example, equipment in the 5G network core network. The core network 120, as a bearer network, provides an interface to the data network, provides communication connection, authentication, management, policy control, and data service bearing for the terminal equipment. Among them, the core network equipment may include: Access and Mobility Management Function (AMF), Session Management Function (SMF), Authentication Server Function (AUSF), Policy Control Function (PCF), User Plane Function (UPF) and other network elements.

[0077] A terminal device, which may be referred to as user equipment, mobile terminal, terminal, mobile station, etc., is a device that provides voice and / or digital connectivity to users. The terminal device may be a variety of electronic devices, including but not limited to smartphones, tablet computers, laptops, desktop computers, wearable devices, augmented reality devices, virtual reality devices, etc.

[0078] Optionally, the client of the application installed in different terminal devices is the same, or the client of the same type of application based on different operating systems. Based on the different terminal platforms, the specific form of the client of the application can also be different, for example, the application client can be a mobile client, a PC client, etc.

[0079] Satellite communications and other non-terrestrial communication networks have significant advantages such as global coverage, long-distance transmission, flexible networking, convenient deployment, and no geographical restrictions. They can provide services for both fixed terminals and various mobile terminals. Non-terrestrial communication networks are introduced into terrestrial networks to provide seamless coverage for terminal devices by deploying base stations or part of base station functions on high-altitude platforms or satellites.

[0080] The ground gateway 130 is used to forward signaling and service data between the satellite base station and the 5G core network. The ground gateway 130 can communicate with the core network equipment by wire; the ground gateway 130 can communicate with the satellite 140 by wireless.

[0081] The coverage of a satellite can reach thousands or even tens of thousands of kilometers, and the coverage of a beam can reach tens of meters or even thousands of meters. In order to support the wide-area coverage of satellites, a satellite is usually equipped with dozens, hundreds, or even more beams. In order to alleviate the contradiction between the small payload of a single satellite and the wide coverage, beam hopping technology can be used for regional coverage. That is, a single satellite is equipped with a small number of beams, which serve a wider coverage area in a time-sharing manner. Only a small number of beams are used for regional coverage in the same time unit, and multiple beams used in different time units cover a wider area.

[0082] The satellite spectrum resource utilization method provided by the embodiment of the present disclosure can also be applied to other scenarios where ground communication systems are integrated with satellite communications. Ground terminal equipment can access the network through the ground base station 110 and connect to the core network 120 through a wireless link, or the ground terminal equipment can access the network through the 5G new air interface technology, and the satellite acts as a 5G base station and is connected to the ground core network 120 through a wireless link, thereby realizing the scenario where the ground communication system is integrated with satellite communications.

[0083] A method for utilizing satellite spectrum resources is provided in an embodiment of the present disclosure. When the spectrum resources of a network device (such as a ground base station) cannot meet preset service conditions, a request to use the satellite spectrum is sent to a ground gateway. The ground gateway generates satellite beam hopping configuration information based on the satellite's beam hopping technology, and sends the beam hopping configuration information to the network device. The network device determines unoccupied time slots based on the received beam hopping configuration information, thereby effectively and reasonably utilizing satellite spectrum resources, avoiding the complexity and high latency of cognitive radio technology, and increasing the service rate and network capacity in the coverage area of ​​the ground base station.

[0084] The present exemplary implementation is described in detail below with reference to the accompanying drawings and embodiments.

[0085] First, a satellite spectrum resource utilization method is provided in an embodiment of the present disclosure, and the method can be executed by any electronic device with computing and processing capabilities. For example, the method can be executed by a network device, such as a ground base station, or by a ground gateway.

[0086] Figure 2 FIG. 2 shows a flow chart of a satellite spectrum resource utilization method provided by an embodiment of the present disclosure. Figure 2 As shown, the satellite spectrum resource utilization method provided in the embodiment of the present disclosure is applied to a network device, and the method includes:

[0087] S202, sending a request to use satellite spectrum to a ground gateway;

[0088] The instruction for requesting to use satellite spectrum in this embodiment is used to determine the specific location or service area of ​​the network device. Specifically, the instruction for requesting to use satellite spectrum includes at least the location information of the network device, the coverage area information of the network device, etc. For example, the location information of the network device may include the longitude and latitude information of the network device, and the coverage area information of the network device may include the boundary information of the service area of ​​the network device, the identification and coding of the coverage area, etc.

[0089] When the spectrum resources of the network equipment cannot meet the business needs of the coverage area, the network equipment sends a request to use the satellite spectrum to the ground gateway through the core network (such as a ground wired transmission link).

[0090] S204. Receive beam hopping configuration information of a target satellite sent by a ground gateway, wherein the target satellite is a satellite in a coverage area of ​​a service network device. The beam hopping configuration information of the target satellite is used to configure beam information transmitted in different time slots, and one beam information corresponds to one coverage area.

[0091] In some embodiments, the beam hopping configuration information is used to configure beam information allocated to a certain coverage area in different time slots, so as to determine the occupancy of a certain time slot according to the beam hopping configuration information. Table 1 shows an example of beam hopping configuration information configuration.

[0092] Table 1

[0093] Time slot number 1 2 3 4 5 6 7 Beam number 1 2 2 3 1 1 2 Area No. 1 2 2 3 1 1 2

[0094] Exemplarily, the ground gateway searches for satellites serving the current coverage area based on the location information or coverage area information of the network device in combination with the satellite's ephemeris information, and sends the beam hopping configuration information of the found satellite to the ground base station via a ground wired transmission link.

[0095] S206, determining an unoccupied time slot based on the beam hopping configuration information of the target satellite;

[0096] The unoccupied time slots of this embodiment include time slots allocated by the satellite to coverage areas other than the coverage area. For example, the ground base station is located in coverage area 1, and the beam information allocated by the satellite to coverage area 1 in time slots 1, 5, and 6 is beam 1; in coverage area 2, the beam information allocated by the satellite to coverage area 2 in time slots 2, 3, and 7 is beam 2; in coverage area 3, the satellite transmits beam 3 to coverage area 3 in time slot 4. For the ground base station in coverage area 1, time slots 2, 3, 4, and 7 are determined to be unoccupied time slots.

[0097] S208. In unoccupied time slots, configure the frequency spectrum of the target satellite as an auxiliary carrier to achieve coordinated communication between the ground and the satellite.

[0098] Based on the received beam hopping configuration information, the ground base station adds the satellite spectrum as an auxiliary carrier in the time slots other than the beam information allocated to the ground base station, and serves the coverage area of ​​the ground base station through carrier aggregation, thereby increasing the service rate and network capacity in the coverage area. For the time slots corresponding to the beam information allocated to the ground base station, the ground base station does not use the satellite spectrum.

[0099] A method for utilizing satellite spectrum resources provided by an embodiment of the present disclosure includes: when the spectrum resources of a network device (such as a ground base station) cannot meet preset service conditions, a request to use the satellite spectrum is sent to a ground gateway; the ground gateway generates satellite beam hopping configuration information based on the satellite beam hopping technology, and sends the beam hopping configuration information to the network device; the network device determines unoccupied time slots based on the received beam hopping configuration information, thereby effectively and reasonably utilizing satellite spectrum resources, avoiding the complexity and high latency of cognitive radio technology, and increasing the service rate and network capacity in the coverage area of ​​the ground base station.

[0100] Figure 3 Another method flow chart of satellite spectrum resource utilization provided by the embodiment of the present disclosure is shown. Figure 2 Based on the embodiment, steps S302 to S304 are added before step S202 to determine whether the current spectrum resources of the network device meet the user's needs. Figure 3 As shown, in one embodiment, the method includes steps S302-S304, S202-S208:

[0101] S302, detecting spectrum resources of network equipment;

[0102] S304, determine whether the spectrum resources of the network device meet the preset service conditions, if yes, return to step S302; if not, execute step S202.

[0103] It should be noted that the specific implementation method of S202 to S208 is the same as that of the above embodiment and will not be repeated here.

[0104] In some embodiments, the preset service condition includes at least one of the following: the spectrum resource of the network device is less than the service demand of the network device coverage area; the spectrum resource of the network device is less than the network capacity of the network device coverage area. It should be noted that in addition to using service demand and network capacity as the criteria for determining whether the network device meets the preset service condition, other implementation methods that can achieve the same function can also be used as the criteria for determining whether the network device meets the preset service condition in the present disclosure, and this application does not make specific limitations.

[0105] The present invention detects the spectrum resources of network equipment, compares the detected spectrum resources with preset service conditions, and then determines whether the ground base station meets the business needs in the coverage area, thereby determining the integration of the ground wireless communication system and the non-ground communication system to improve the user experience.

[0106] In one embodiment, after configuring the frequency spectrum of the target satellite as an auxiliary carrier in the unoccupied time slot in step S208 to implement the earth-satellite coordinated communication, the method further includes:

[0107] When receiving satellite change information sent by the ground gateway, the spectrum of the target satellite is released.

[0108] During the process of the satellite executing according to the beam hopping configuration information, if the satellite's ephemeris information changes, for example, the satellite coverage area changes and the target satellite can no longer provide services for the coverage area of ​​the ground base station, the ground gateway will send the satellite change information to the ground base station through the ground wired transmission link, and the ground base station will release the spectrum of the target satellite.

[0109] In another embodiment, after configuring the frequency spectrum of the target satellite as an auxiliary carrier in the unoccupied time slot in step S208 to implement the earth-satellite coordinated communication, the method further includes:

[0110] Receive change information of beam hopping configuration information of a target satellite sent by a ground gateway;

[0111] If the state of the unoccupied time slots of the beam hopping configuration information of the target satellite changes, the spectrum of the target satellite is reconfigured.

[0112] During the process of the satellite executing according to the beam hopping configuration information, when there is a change in the beam hopping configuration information, for example, the time slots corresponding to the beam information of different coverage areas are readjusted according to the business needs of the coverage area, the ground gateway sends the changed beam hopping configuration information to the ground base station through the ground wired transmission link, and the ground base station reconfigures the satellite spectrum according to the changed beam hopping configuration information.

[0113] Exemplarily, when the time slot in the changed beam hopping configuration information changes from an unoccupied state to an occupied state, the spectrum of the target satellite is released in the time slot; when the time slot in the changed beam hopping configuration information changes from an occupied state to a non-occupied state, the time slot of the target satellite is configured in the time slot as an auxiliary carrier.

[0114] The satellite spectrum resource utilization method of the disclosed embodiment detects satellite change information or beam hopping configuration information change information in real time, thereby timely grasping the status of the satellite or beam hopping configuration information and making timely adjustments.

[0115] Figure 4 FIG. 2 is a flow chart of another satellite spectrum resource utilization method provided by an embodiment of the present disclosure. Figure 4 The satellite spectrum resource utilization method of this embodiment is applied to a ground gateway station, and the method includes:

[0116] S402, receiving a request to use a satellite spectrum from a network device;

[0118] In one embodiment, the ground gateway receives the satellite spectrum request sent by the network device through the ground wired transmission link, searches for the satellite corresponding to the coverage area of ​​the network device according to the location information of the network device (such as the ground base station) and the ephemeris information of the satellite controlled by the ground gateway, and obtains the beam hopping configuration information of the satellite, and sends the obtained beam hopping configuration information of the target satellite to the ground base station through the ground wired transmission link. The ephemeris information of the satellite includes the satellite's orbit, the start and end time of the coverage area, and the operation duration.

[0119] Figure 5 A flowchart of another satellite spectrum resource utilization method provided by an embodiment of the present disclosure is shown. Figure 4 On the basis of the embodiment, steps S502 to S504 are added before step S402, so that the ground gateway generates beam hopping configuration information of the satellite it controls. In one embodiment, the method includes steps S502 to S504, S402 to S404, specifically, the method includes:

[0120] S502, generating beam hopping configuration information of each satellite controlled by the ground gateway according to the satellite service conditions in the satellite coverage area;

[0121] S504: Send the beam hopping configuration information to the corresponding satellite for execution.

[0122] It should be noted that the specific implementation method of steps S402 to S404 is the same as that of the above embodiment and will not be repeated here.

[0123] The ground gateway generates beam hopping configuration information according to the satellite service conditions in the coverage area, as shown in Table 1, and sends it to the corresponding satellite for execution through the satellite-to-ground feeder link.

[0124] In one embodiment, after sending the beam hopping configuration information of the target satellite to the network device in S404, the method further includes:

[0125] Generate satellite change information based on the ephemeris information of each satellite;

[0126] Send satellite change information to network devices.

[0127] It should be noted that the ground gateway monitors the satellite's ephemeris information in real time, generates satellite change information based on the ephemeris information, and sends the satellite change information to the ground base station through the ground wired transmission link, so that the ground base station releases the spectrum of the target satellite according to the satellite change information.

[0128] In another embodiment, after sending the beam hopping configuration information of the target satellite to the network device in S404, the method further includes:

[0129] Monitor the change information of the beam hopping configuration information of the target satellite;

[0130] When the beam hopping configuration information of the target satellite is detected to have changed, it is sent to the network device.

[0131] During the process of the satellite executing according to the beam hopping configuration information, when there is a change in the beam hopping configuration information, for example, the time slots corresponding to the beam information of different coverage areas are readjusted according to the business needs of the coverage area, the ground gateway sends the changed beam hopping configuration information to the ground base station through the ground wired transmission link, and the ground base station reconfigures the satellite spectrum according to the changed beam hopping configuration information.

[0132] The satellite spectrum resource utilization method of the disclosed embodiment detects satellite change information or beam hopping configuration information change information in real time, thereby timely grasping the status of the satellite or beam hopping configuration information and making timely adjustments.
