CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies.

[0135] The heterogeneous three-dimensional hierarchical network in this article may include: a terrestrial mobile communication subnetwork and a non-terrestrial mobile communication subnetwork.

[0136] The terminal in this article supports both communication with non-terrestrial mobile communication subnetworks and communication with terrestrial mobile communication subnetworks.

[0137] Optionally, the cell coverage area formed by the non-ground mobile communication subnetwork is larger than the cell coverage area formed by the ground mobile communication subnetwork; or, within the cell coverage area formed by the ground mobile communication subnetwork, there is also coverage formed by the non-ground mobile communication subnetwork; or, within the cell coverage area formed by the non-ground mobile communication subnetwork, there may be no coverage formed by the ground mobile communication subnetwork.

[0138] Among them, the ground mobile communication subnet uses a cellular base station (such as a macrocellular base station or a microcellular base station) or a direct terminal to send and receive terminal signals. Alternatively, the non-ground mobile communication subnet can use satellites, high-altitude platforms, drones, civil aircraft and other aerospace equipment to send and receive terminal signals, and use ground signal gateways to send and receive feed signals for aerospace equipment.

[0139] See also Figure 1 An embodiment of the present invention provides a control method in a heterogeneous three-dimensional layered network. The execution subject of the method may be a network control unit. The specific steps include: step 101, step 102 and step 103.

[0140] Step 101: Obtain the coverage mode of the terminal;

[0141] In the implementation of the present invention, the network control unit is used to coordinate the communication between the non-ground mobile communication subnetwork and the ground mobile communication subnetwork and the terminal. Optionally, the network control unit may include: network units of each layer of subnetworks, such as network control units of each layer of subnetworks. Furthermore, the network control unit may be a separate device, or its functions may be integrated in each layer of subnetworks.

[0142] In the implementation of the present invention, the coverage mode of the terminal refers to the mode in which the terminal is covered by a heterogeneous three-dimensional layered network, which may include: single-layer subnetwork coverage and multi-layer subnetwork coverage, wherein single-layer subnetwork coverage may refer to the coverage of a terrestrial mobile communication subnetwork or a non-terrestrial mobile communication subnetwork, and multi-layer subnetwork coverage may refer to the coverage of a non-terrestrial mobile communication subnetwork, or the coverage of a terrestrial mobile communication subnetwork and a non-terrestrial mobile communication subnetwork.

[0143] For example, the non-terrestrial mobile communication subnetwork may be a satellite communication subnetwork, and the network side devices in the satellite communication subnetwork may include: a satellite constellation and a ground gateway station. The satellite constellation receives and sends terminal signals and ground gateway station signals, and the ground gateway station receives and sends satellite feed signals.

[0144] For transparent forwarding satellite constellations, the communication link transmission mode of the satellite communication subnetwork is "terminal-satellite constellation-gateway". Alternatively, for on-board processing satellite constellations, the communication link transmission mode of the satellite communication subnetwork is "terminal-satellite constellation".

[0145] It can be understood that the satellite constellation can form various forms such as single-layer coverage at the same orbital altitude, multi-layer coverage at the same orbital altitude, and multi-layer coverage at different orbital altitudes. That is, the satellite communication subnetwork can include: multi-layer subnetworks of satellite constellations at different orbital altitudes, wherein the multi-layer subnetwork can include one of the following: (1) a three-layer subnetwork of a geostationary orbit (GEO) constellation, a medium earth orbit (MEO) constellation, and a low earth orbit (LEO) constellation; (2) a two-layer subnetwork of a GEO constellation and a MEO constellation; (3) a two-layer subnetwork of a GEO constellation and a LEO constellation; (4) a two-layer subnetwork of a MEO constellation and a LEO constellation; (5) a two-layer subnetwork of a LEO constellation and a LEO constellation.

[0146] It is understandable that satellite constellations at different orbital altitudes can be processed using the same or different ground gateways.

[0147] In the implementation of the present invention, the terminal supports independent working mode, intra-layer carrier aggregation mode, and cross-layer carrier aggregation mode, wherein the intra-layer carrier aggregation mode can also be called a single-layer subnetwork carrier aggregation mode, and the cross-layer carrier aggregation mode refers to a carrier aggregation mode between different layers, such as a carrier aggregation mode between multiple layers of non-terrestrial mobile communication subnetworks, or a carrier aggregation mode between a terrestrial mobile communication subnetwork and a non-terrestrial mobile communication subnetwork.

[0148] Step 102: If the coverage mode is single-layer sub-network coverage, the terrestrial mobile communication sub-network or non-terrestrial mobile communication sub-network corresponding to the single-layer sub-network coverage is set to an independent working mode or an intra-layer carrier aggregation mode;

[0149] Among them, the independent working mode refers to the single-layer sub-network providing services to the terminal, and the intra-layer carrier aggregation mode refers to the intra-layer carrier aggregation mode of the single-layer sub-network providing services to the terminal.

[0150] Step 103: If the coverage mode is multi-layer subnetwork coverage, the multi-layer subnetwork covers the corresponding non-terrestrial mobile communication subnetwork, or the multi-layer subnetwork covers the corresponding non-terrestrial mobile communication subnetwork and terrestrial mobile communication subnetwork, and is set to a cross-layer carrier aggregation mode.

[0151] The non-terrestrial mobile communication subnetwork and the terrestrial mobile communication subnetwork adopt the same or unified wireless access technology.

[0152] The above cross-layer carrier aggregation mode may also be referred to as an inter-layer carrier aggregation mode.

[0153] Optionally, in step 103, it is configured that in the cross-layer carrier aggregation mode, the signal of the sub-network with the largest coverage is preferably used as the main carrier.

[0154] That is, the network control unit can decide whether to perform inter-layer carrier aggregation based on whether the sub-network corresponding to the current operation of the terminal is single-layer coverage or multi-layer coverage. If there is only single-layer coverage, the sub-network corresponding to the coverage is set to an independent working mode or an intra-layer carrier aggregation mode. If there are multiple layers of coverage, the sub-networks corresponding to each layer of coverage are set to an inter-layer carrier aggregation mode.

[0155] In some embodiments, after step 101, or after step 103, Figure 1 The method shown may also include: obtaining the coverage of the terrestrial mobile communication subnetwork and / or the non-terrestrial mobile communication subnetwork; and using the signal of the subnetwork with the largest coverage as the main carrier.

[0156] In some embodiments, Figure 1 The method shown may also include: configuring one or more primary carriers for the terrestrial mobile communication subnetwork and / or the non-terrestrial mobile communication subnetwork. It is understandable that the manner of configuring the primary carriers and the order of execution are not specifically limited in the embodiments of the present invention.

[0157] In some embodiments, the main carrier is used for access, synchronization, control or data transmission at a first rate (such as a low rate) of the terminal, and the auxiliary carrier corresponding to the main carrier is used for data transmission at a second rate (such as a high rate) of the terminal, and the first rate is less than the second rate.

[0158] In some embodiments, Figure 1 The method shown may further include: notifying the terminal of the working mode and / or working bandwidth of the cell where the terminal is located. It is understandable that in the embodiment of the present invention, there is no specific limitation on the notification method and execution order of the network control unit.

[0159] In some embodiments, Figure 1 The method shown may also include: sending first information, wherein the first information indicates one or more combinations of the following:

[0160] (1) the operating frequency of the terrestrial mobile communication subnetwork and / or the non-terrestrial mobile communication subnetwork;

[0161] (2) the service time of the non-terrestrial mobile communication subnetwork;

[0162] (3) The beam angle of the non-terrestrial mobile communication subnetwork.

[0163] That is, the network control unit can coordinate multiple sub-networks based on operating frequency, service time, and non-terrestrial network beam angle, determine the allocation method of the sub-network operating frequency, service time, and non-terrestrial network beam angle, and avoid interference between sub-networks.

[0164] It can be understood that in the embodiment of the present invention, there is no specific limitation on the first information notified by the network control unit and the execution order.

[0165] In some embodiments, Figure 1 The method shown may also include: obtaining the working status of the terrestrial mobile communication subnetwork and / or the non-terrestrial mobile communication subnetwork; and sending second information according to the working status, wherein the second information instructs the terminal to perform subnetwork switching.

[0166] That is, the network control unit can detect the status of each layer of sub-network that is communicating. When an abnormal situation occurs, the network control unit can send coordination information in advance, shut down the signal sending of the layer of sub-network or prohibit users from accessing the layer of sub-network, and notify users to switch to other layers of sub-network.

[0167] It can be understood that in the embodiment of the present invention, there is no specific limitation on the manner in which the network control unit notifies the second information and the execution order.

[0168] In some embodiments, Figure 1 The method shown may also include: dynamically configuring or statically configuring the working bandwidth of the non-terrestrial mobile communication subnetwork and / or the terrestrial mobile communication subnetwork. It is understood that in the embodiment of the present invention, the manner in which the network control unit configures the working bandwidth of each layer of subnetwork and the order of execution are not specifically limited.

[0169] For example, for static configuration, each layer of subnetwork only works in the allocated working bandwidth; for dynamic configuration, each layer of subnetwork can work in the entire system bandwidth, but the actual occupied bandwidth may be related to factors such as the system capacity and / or rate requirements, and the total actual occupied bandwidth of all subnetworks is less than or equal to the entire system bandwidth; optionally, different subnetworks can be configured as different carriers or different partial bandwidths (BWP).

[0170] Optionally, the frequency bands used by the wireless signals of the non-terrestrial mobile communication subnetwork and the terrestrial mobile communication subnetwork providing cell coverage in the same area are obtained by dividing the bandwidth of the communication system.

[0171] For example, non-terrestrial mobile communication sub-networks use lower frequency bands in the system bandwidth.

[0172] Optionally, the bandwidth division may be a pre-allocated static division, that is, the wireless signals of the non-terrestrial mobile communication subnetwork and the wireless signals of the terrestrial mobile communication subnetwork respectively operate at fixed bandwidths.

[0173] Optionally, the bandwidth division may be a dynamic division that changes at any time, that is, the working bandwidth of the wireless signal of the non-terrestrial mobile communication subnetwork and the wireless signal of the terrestrial mobile communication subnetwork may change. Exemplarily, the network control unit calculates the working bandwidth required by the non-terrestrial mobile communication subnetwork and the terrestrial mobile communication subnetwork respectively according to the capacity and / or data transmission rate requirements; and again exemplarily, the network control unit dynamically adjusts the working bandwidth of the non-terrestrial mobile communication subnetwork and the terrestrial mobile communication subnetwork.

[0174] It can be understood that the total actual occupied bandwidth of all sub-networks is less than or equal to the entire system bandwidth.

[0175] In an embodiment of the present invention, the non-terrestrial mobile communication subnetwork and the terrestrial mobile communication subnetwork adopt the same or unified wireless access technology, such as 4G, 5G, 6G and other wireless access technologies, that is, the heterogeneous three-dimensional coverage formed by the non-terrestrial mobile communication and the terrestrial mobile communication can be regarded as a unified network system for communication, avoiding the traditional "dual system" working mode of the non-terrestrial communication system and the terrestrial mobile communication system, which brings about the waste of wireless resources, system construction, equipment implementation and other aspects.

[0183] In some embodiments, Figure 2The method shown may also include:

[0184] If the working mode of the terminal is the intra-layer carrier aggregation mode, access, synchronization, control and / or data transmission at a first rate are performed on a primary carrier, and data transmission at a second rate is performed on a secondary carrier corresponding to the primary carrier, where the first rate is less than the second rate;

[0185] In some embodiments, Figure 2 The method shown may also include:

[0186] If the working mode of the terminal is a cross-layer carrier aggregation mode, access, synchronization, control and / or data transmission at a first rate (such as a low rate) is performed in the subnet where the main carrier is located, and data transmission at a second rate (such as a high rate) is performed in the subnet where the auxiliary carrier corresponding to the main carrier is located, and the first rate is less than the second rate.

[0187] In an embodiment of the present invention, the non-terrestrial mobile communication subnetwork and the terrestrial mobile communication subnetwork adopt the same or unified wireless access technology, such as 4G, 5G, 6G and other wireless access technologies, that is, the heterogeneous three-dimensional coverage formed by the non-terrestrial mobile communication and the terrestrial mobile communication can be regarded as a unified network system for communication, avoiding the traditional "dual system" working mode of the non-terrestrial communication system and the terrestrial mobile communication system, which brings about the waste of wireless resources, system construction, equipment implementation and other aspects.

[0211] In some implementations, the network control unit dynamically or statically configures the operating bandwidth of the non-terrestrial mobile communication subnetwork and the operating bandwidth of the terrestrial mobile communication subnetwork.

[0216] In an embodiment of the present invention, the non-terrestrial mobile communication subnetwork and the terrestrial mobile communication subnetwork adopt the same or unified wireless access technology, such as 4G, 5G, 6G and other wireless access technologies, that is, the heterogeneous three-dimensional coverage formed by the non-terrestrial mobile communication and the terrestrial mobile communication can be regarded as a unified network system for communication, avoiding the traditional "dual system" working mode of the non-terrestrial communication system and the terrestrial mobile communication system, which brings about the waste of wireless resources, system construction, equipment implementation and other aspects.

[0217] The implementation manner of the present invention is described below in conjunction with Example 1 and Example 2.

[0218] Embodiment 1: A three-layer heterogeneous three-dimensional network of GEO constellation + LEO constellation + ground cellular base station.

[0219] The non-terrestrial mobile communication subnetwork includes: a GEO constellation, a LEO constellation, and a ground gateway station that is communicatively connected to the GEO constellation and the LEO constellation;

[0220] The ground mobile communication subnetwork includes: a ground base station;

[0221] The network control unit is communicatively connected with the ground gateway station and the ground base station respectively.

[0222] like Figure 4 As shown in the figure, it is assumed that a communication system consists of a GEO constellation, a LEO constellation, a ground gateway, a ground cellular base station, a network control unit and a terminal, forming a three-layer heterogeneous three-dimensional layered coverage.

[0223] From the perspective of the terminal, the sub-network composed of the GEO constellation and the ground gateway station forms the first layer of coverage with the largest coverage area, the sub-network composed of the LEO constellation and the ground gateway station forms the second layer of coverage with the second largest coverage area, and the ground cellular base station forms the third layer of coverage with the smallest area. That is, for the area covered by the ground cellular base station where the terminal is located, there is also coverage by the fixed GEO satellite and the fast-moving LEO satellite.

[0224] Under the unified coordination of the network control unit, the occupied bandwidth of the sub-networks formed by each layer of coverage is divided statically or dynamically.

[0225] Assuming that the system's operating bandwidth is B MHz, in a static mode, the total bandwidth B MHz is fixedly divided into three non-overlapping segments, assuming they are B1, B2, and B3, then B1+B2+B3≤B. The three bandwidth segments are allocated to the three-layer covered subnetworks, so that the three-layer covered subnetworks are designed only according to the given bandwidths, such as the GEO constellation subnetwork only works in bandwidth B1, the LEO constellation subnetwork only works in bandwidth B2, and the ground base station subnetwork only works in bandwidth B3.

[0226] Assuming that the system's working bandwidth is B MHz, in a dynamic mode, the sub-networks of the three-layer coverage are designed according to the entire working bandwidth B, but the actual working bandwidth is dynamically changing, which is related to factors such as the system capacity and rate requirements in a specific area and at a specific time. Without loss of generality, assuming that the terminal is in the i-th area, the corresponding working bandwidths of the three-layer coverage sub-networks are B 1,i , B 2,i , B 3,i , then B 1,i +B 2,i +B 3,i ≤B; Assuming that the terminal is in the jth area, the corresponding working bandwidth of the 3-layer covered sub-network is B1,j , B 2,j , B 3,j , then B 1,j +B 2,j +B 3,j ≤B; because the system capacity and rate requirements of the i-th area and the j-th area are different, there is B 1,i ≠B 1,j , B 2,i ≠B 2,j , B 3,i ≠B 3,j .

[0227] Under the unified coordination of the network control unit, the sub-networks covered by each layer provide services to the terminal through carrier aggregation.

[0228] It can be understood that the first layer coverage formed by GEO satellites can be used as the main carrier for terminal access, synchronization, control and low-rate data transmission; the second layer coverage formed by LEO satellites and the third layer coverage formed by ground base stations can both be used as auxiliary carriers for high-rate data transmission of terminals.

[0229] During the communication between the terminal and the network, the network will monitor the changes in its own working status in real time, and the terminal will also notify the network of its own information in real time, so that the network can make better judgments and processing on the current working status. For example, if the network detects that the satellite of one layer of the multi-layer constellation sub-network connected to the terminal is unavailable, the network will notify the terminal to disconnect from the unavailable satellite and switch to other constellation sub-networks and / or ground sub-networks for communication.

[0230] It should be noted that Figure 4 The terminal in can be directly connected to the GEO constellation for communication, and the ground gateway GW2 can be connected to the satellites in one or more second LEO satellite constellations for communication.

[0231] Embodiment 2: A three-layer heterogeneous stereo network of LEO constellation + ground cellular base station.

[0232] like Figure 5 As shown in the figure, it is assumed that a communication system consists of a LEO constellation, a ground gateway, a ground cellular base station, a network control unit and a terminal, forming a three-layer heterogeneous three-dimensional layered coverage.

[0233] The non-terrestrial mobile communication subnetwork includes: a LEO constellation and a ground gateway station communicatively connected to the LEO constellation;

[0234] The ground mobile communication subnetwork includes: a ground base station;

[0235] The network control unit is communicatively connected with the ground gateway station and the ground base station respectively.

[0236] From the terminal's perspective, the subnetwork composed of LEO constellations and ground gateways forms a two-layer coverage of control beams and spot beams, where control beams are the first layer with the largest coverage area, spot beams are the second layer with the second largest coverage area, and ground cellular base stations form the third layer with the smallest area. That is, for the area covered by the ground cellular base station where the terminal is located, there is also control beam coverage and spot beam coverage of the fast-moving LEO satellite.

[0237] Under the unified coordination of the network control unit, the occupied bandwidth of the sub-networks formed by each layer of coverage is divided statically or dynamically.

[0238] Assuming that the system's operating bandwidth is B MHz, in a static mode, the total bandwidth B MHz is fixedly divided into three non-overlapping segments, assuming they are B1, B2, and B3, then B1+B2+B3≤B. The three bandwidths are allocated to the three-layer covered subnetworks, respectively, so that the three-layer covered subnetworks are designed only according to the given bandwidths, such as the control beam subnetwork of the LEO constellation only works in bandwidth B1, the spot beam subnetwork of the LEO constellation only works in bandwidth B2, and the ground base station subnetwork only works in bandwidth B3.

[0239] Assuming that the system's working bandwidth is B MHz, in a dynamic mode, the sub-networks of the three-layer coverage are designed according to the entire working bandwidth B, but the actual working bandwidth is dynamically changing, which is related to factors such as the system capacity and rate requirements in a specific area and at a specific time. Without loss of generality, assuming that the terminal is in the i-th area, the corresponding working bandwidths of the three-layer coverage sub-networks are B 1,i , B 2,i , B 3,i , then B 1,i +B 2,i +B 3,i ≤B; Assuming that the terminal is in the jth area, the corresponding working bandwidth of the 3-layer covered sub-network is B 1,j , B 2,j , B 3,j , then B 1,j +B 2,j +B 3,j ≤B; because the system capacity and rate requirements of the i-th area and the j-th area are different, there is B 1,i ≠B 1,j , B 2,i ≠B 2,j , B 3,i ≠B 3,j .

[0240] Under the unified coordination of the network control unit, the sub-networks covered by each layer provide services to the terminal through carrier aggregation.

[0241] It can be understood that the first layer coverage formed by the control beam of the LEO satellite can be used as the main carrier for terminal access, synchronization, control and low-rate data transmission; the second layer coverage formed by the spot beam of the LEO satellite and the third layer coverage formed by the ground base station can both be used as auxiliary carriers for high-rate data transmission of the terminal.

[0242] During the communication between the terminal and the network, the network will monitor the changes in its working status in real time, and the terminal will also notify the network of its own information in real time, so that the network can make better judgments and processing on the current working status. For example, if the network detects that the ground sub-network to which the terminal is connected is unavailable, the network will notify the terminal to disconnect from the ground sub-network and switch to communicating with the satellite sub-networks.
