Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0032] In view of the problems existing in the related art, the present disclosure proposes an aviation communication method. Figure 1 A schematic diagram of the process of the aviation communication method is shown, such as Figure 1 As shown, the aviation communication method includes at least the following steps:

[0033] Step S110: Determine the target construction operator corresponding to the airborne terminal.

[0034] Step S120. Based on the sharing agreement, detect the target signal of the target aeronautical mobile network allocated to the target construction operator; the target aeronautical mobile network is jointly constructed by different construction operators, and the target aeronautical mobile network includes ground-to-air base stations, ground cellular base stations and ground signal gateways; the sharing agreement is an agreement for sharing the target aeronautical mobile network between different construction operators.

[0035] Step S130: If the target signal meets the link switching condition, access the mobile core network through different link combinations of the target aviation mobile network to achieve aviation communication.

[0036] In the method and apparatus provided in the exemplary embodiments of the present disclosure, on the one hand, if the target signal meets the link switching condition, it accesses the mobile core network through different link combinations, thereby ensuring that when the target signal is in different situations, there are corresponding links that allow the airborne terminal to access the mobile core network, thereby ensuring the continuity of aviation communications and meeting the user's demand for mobile bandwidth access services on the aircraft; on the other hand, the target aviation network is jointly built by different operators, and different construction operators can share the target aviation mobile network, thereby realizing the co-construction and sharing of the target aviation mobile network and reducing the construction cost of the target aviation mobile network.

[0037] In step S110, a target construction operator corresponding to the airborne terminal is determined.

[0038] In the exemplary embodiments of the present disclosure, an airborne terminal refers to a terminal that needs to implement communication on an aircraft. Specifically, the airborne terminal can be a mobile phone, a tablet computer, a laptop computer, or a phone watch, and this exemplary embodiment does not specifically limit this.

[0039] An operator refers to a supplier that provides network services. Specifically, an operator can be China Telecom, China Unicom, China Mobile, or any operator developed in the future. This exemplary embodiment does not specifically limit this. It is worth noting that the target aviation mobile network proposed later is jointly built by the above-mentioned operators. Therefore, the above-mentioned operators can be called construction operators, among which the construction operator corresponding to the airborne terminal is the target construction operator.

[0040] For example, the onboard terminal is the mobile phone of user XX, and the target construction operator corresponding to the mobile phone of user XX is China Telecom.

[0041] In this exemplary embodiment, determining the target construction operator corresponding to the airborne terminal helps to subsequently determine the link to access the mobile core network according to the target construction operator, thereby achieving aviation communication.

[0042] In step S120, based on the sharing agreement, the target signal of the target aeronautical mobile network allocated to the target construction operator is detected; the target aeronautical mobile network is jointly constructed by different construction operators, and the target aeronautical mobile network includes ground-to-air base stations, ground cellular base stations and ground signal gateways; the sharing agreement is an agreement for sharing the target aeronautical mobile network between different construction operators.

[0043] In an exemplary embodiment of the present disclosure, the sharing agreement refers to an agreement agreed upon by different construction operators, and the agreed content is how different construction operators share the target aeronautical mobile network.

[0044] The target aeronautical mobile network refers to a network that completely covers the aircraft's flight route and is used for airborne terminal communications. The target aeronautical mobile network includes ground-to-air base stations, ground cellular base stations, and ground gateways. Among them, the ground cellular (IMT, International Mobile Telecommunications) base station refers to a device in a ground cellular mobile communication system that can wirelessly communicate with a communication terminal device. The ground-to-air (ATG, Air to Ground) base station refers to a device in a ground-to-air wireless communication network that can wirelessly communicate with a communication terminal device. The ground gateway refers to the core of the mobile satellite communication system, which is used to connect the public telephone network and the mobile satellite communication network to provide voice and data transmission channels for airborne terminals. The ground transmission network refers to a network built on the ground for transmitting data.

[0045] Since the target aeronautical mobile network is jointly constructed by different construction operators, and different construction operators have agreed on a sharing agreement, different construction operators can share ground-to-air base stations, ground cellular base stations and ground signal gateways. Moreover, based on the sharing agreement, the target signal allocated to the target construction operator by the target aeronautical mobile network can be detected.

[0046] For example, based on the sharing agreement, the target signal assigned to China Telecom by the ground cellular base station can be detected.

[0047] In this exemplary embodiment, the detection of the target signal helps to subsequently connect the airborne terminal to the mobile core network through different link combinations according to different situations of the target signal to ensure the continuity of aviation communications.

[0048] In an optional embodiment, the ground cellular base station, the ground-to-air base station and the ground gateway support access to mobile core networks corresponding to multiple operators.

[0049] The multiple operators refer to suppliers that provide network services. Specifically, the multiple operators include China Mobile, China Unicom and China Telecom, which is not specifically limited in this exemplary embodiment.

[0050] It is worth noting that ground cellular base stations, ground-to-air base stations and ground gateways support the access of multiple operators' mobile core networks. Specifically, different operators can undertake the construction of part of IMT base stations, ATG base stations and satellite gateways, and jointly build in different regions to form a target aviation mobile network that fully covers the aircraft routes. Among them, each operator can independently build a mobile core network to ensure the independence of their respective users and services, but it is necessary to share the air interface of ground cellular base stations, ground-to-air base stations and ground gateways to achieve the sharing of the target aviation mobile network.

[0051] For example, China Telecom, China Mobile and China Unicom share the air interface of ground cellular base stations, ground-to-air base stations and ground gateways so that multiple operators can share the target aeronautical mobile network.

[0052] In this exemplary embodiment, ground cellular base stations, ground-to-air base stations and ground gateways support mobile core network access corresponding to multiple operators, which allows multiple operators to share the same target aeronautical mobile network, reducing the operating costs and construction costs of the target aeronautical mobile network.

[0053] In step S130, if the target signal meets the link switching condition, the mobile core network is accessed through different link combinations of the target aeronautical mobile network to achieve aeronautical communication.

[0054] In an exemplary embodiment of the present disclosure, a link switching condition refers to a condition used to measure a target signal, and when the target signal satisfies the link switching condition, a corresponding link combination can be determined in the target aviation mobile network to connect the airborne terminal to the mobile core network through the link combination.

[0055] The target aeronautical mobile network refers to a network that effectively integrates ATG services, IMT networks and satellite communications. In addition, the target aeronautical mobile network not only completely covers the flight routes of aircraft, but also has multiple link combinations in the target aeronautical mobile network. Different link combinations are suitable for different link switching conditions. The mobile core network refers to the network used to exchange and transmit information with other communication systems.

[0056] For example, if target signal A is detected, and the IMT network status can be determined to be good through target signal A. Based on this, the airborne terminal can be connected to the mobile core network through a link composed of a ground cellular base station and a ground transmission network.

[0057] In an optional embodiment, the target aeronautical mobile network also includes a communication satellite and a ground transmission network; different link combinations include a first link, a second link, a third link and a fourth link; wherein the first link is composed of a ground cellular base station and a ground transmission network, the second link is composed of a ground-to-air base station and a ground transmission network, the third link is composed of a ground-to-air base station, a communication satellite, a ground gateway and a ground transmission network, and the fourth link is composed of a communication satellite, a ground gateway and a ground transmission network.

[0058] Among them, a communication satellite refers to a device built by humans, launched into the sky by a space flight vehicle such as a rocket or an aircraft, and orbiting the earth like a natural satellite. The communication satellite can be used to communicate with an airborne terminal. Specifically, the communication satellite can be the Tiantong-1 satellite, or any foreign high-throughput communication satellite, which is not particularly limited in this exemplary embodiment.

[0059] The ground gateway station refers to the core of the mobile satellite communication system, which is used to connect the public telephone network and the mobile satellite communication network and provide voice and data transmission channels for airborne terminals. The ground transmission network refers to the network built on the ground for data transmission.

[0060] For example, the target aeronautical mobile network includes IMT base stations, ATG base stations, Tiantong-1 satellites, ground gateways and ground transmission networks.

[0061] Specifically, there are four links in the target aeronautical mobile network, namely the first link, the second link, the third link and the fourth link. The first link refers to the link composed of the IMT base station and the ground transmission network, the second link refers to the link composed of the ATG base station and the ground transmission network, the third link refers to the link composed of the IMT base station, the communication satellite, the ground gateway and the ground transmission network, and the fourth link refers to the link composed of the communication satellite, the ground gateway and the ground transmission network.

[0062] For example, there are four links in the target aeronautical mobile network, of which the first link consists of an IMT base station and a ground transmission network, the second link consists of an ATG base station and a ground transmission network, the third link consists of an IMT base station, Tiantong-1, a ground gateway and a ground transmission network, and the fourth link consists of Tiantong-1, a ground gateway and a ground transmission network.

[0063] In this exemplary embodiment, different link combinations include a first link, a second link, a third link, and a fourth link. Moreover, the structures of these four links are different, which lays a foundation for selecting different link combinations for different first signals or second signals in the future.

[0064] In an optional embodiment, if the target signal meets the link switching condition, access to the mobile core network is achieved through different link combinations of the target aviation mobile network to achieve aviation communication, including: if a first signal strength of a first signal assigned by a ground cellular base station to the target bearer operator is detected, and the signal attribute of the first signal meets the first signal coverage condition, access to the mobile core network is achieved through the first link to achieve aviation communication.

[0065] The first signal is a signal allocated by the ground cellular base station to the target operator. It is worth noting that at this time, the ground cellular base station can allocate signals to different operators, and the airborne terminals corresponding to different operators can only receive the signals allocated by the ground cellular base station to the corresponding operator.

[0066] The first signal strength refers to the signal strength of the first signal. The signal attribute of the first signal refers to the attribute information related to the first signal. Specifically, the signal attribute of the first signal may be the coverage of the first signal, the intensity range of the first signal strength of the first signal, the first signal bandwidth of the first signal, or any attribute of the first signal, which is not particularly limited in this exemplary embodiment.

[0067] The first signal coverage condition refers to a condition indicating that the first signal coverage is good. Specifically, the first signal coverage condition may be a condition that the variation range of the first signal strength is within a specific interval, or a condition that the coverage range of the first signal includes a specified range, or a condition that the variation trend of the first signal strength shows an upward trend. This exemplary embodiment does not make any special limitation to this.

[0068] For example, if the first signal strength of the first signal assigned to China Telecom by the ground cellular base station is detected, it proves that the first signal exists at this time. And, if the change trend of the first signal strength of the first signal shows an upward trend under the premise of detecting the first signal strength corresponding to the first signal, the airborne terminal can be connected to the mobile core network through the first link composed of the IMT base station and the ground transmission network.

[0069] It is worth noting that the entire flight process of an aircraft is roughly divided into three stages, wherein the first state is the take-off stage, the second state is the cruising stage, and the third state is the landing stage. The situation in which the first signal strength corresponding to the first signal is detected and the signal attribute of the first signal meets the first signal coverage condition usually occurs during the take-off or landing stage of the aircraft.

[0070] In this exemplary embodiment, when the first signal strength is detected and the signal attribute of the first signal satisfies the first signal coverage condition, the mobile core network is accessed through the first link, which meets the user's demand for mobile broadband access service during the take-off or landing phase of the aircraft.

[0071] In an alternative embodiment, Figure 2 A schematic diagram of a process of accessing a mobile core network through different link combinations in an aviation communication method is shown, such as Figure 2 As shown, the method includes at least the following steps: in step S210, if a first signal strength is detected and a second signal strength of a second signal allocated by the ground-to-air base station to the target contracting operator is detected, based on a sharing protocol, a first available bandwidth allocated by the ground cellular base station to the target contracting operator and a second available bandwidth allocated by the ground-to-air base station to the target contracting operator are determined.

[0072] After the aircraft takes off, the flight altitude will gradually increase. Since the main lobe of the IMT base station antenna is facing downward, the IMT network can only maintain wireless communication with the airborne terminal through the upper side lobe of the IMT base station antenna. As the flight altitude further increases, the IMT base station signal gradually weakens, and since the main lobe of the ATG base station antenna is facing upward, the airborne terminal will gradually receive the second signal.

[0073] Based on this, if the first signal strength and the second signal strength of the second signal allocated by the ATG base station to the target construction operator are detected, the first signal and the second signal can be received at the same time, proving that the aircraft is in the stage of increasing altitude at this time.

[0074] Since two signals can be received, in order to determine the link combination in the target aeronautical mobile network, it is necessary to determine the first available bandwidth allocated to the target operator by the IMT base station, and it is also necessary to determine the second available bandwidth allocated to the target operator by the ATG base station.

[0075] The first available bandwidth refers to the amount of data that the IMT base station can actually transmit to the target operator within a fixed time, and the second available bandwidth refers to the amount of data that the ATG base station can actually transmit to the target operator within a fixed time.

[0076] For example, if the first signal strength and the second signal strength are detected, it proves that both the first signal and the second signal can be received at this time. Therefore, the first available bandwidth BW1 allocated to China Telecom by the IMT base station is determined, and the second available bandwidth BW2 allocated to China Telecom by the ATG base station is also determined.

[0077] In step S220, if the first available bandwidth is greater than the second available bandwidth, the mobile core network is accessed through the first link to implement aviation communication.

[0078] If the first available bandwidth is greater than the second available bandwidth, it is proved that at this time, using the first link composed of the IMT base station and the ground transmission network to connect the airborne terminal to the mobile core network can obtain a higher data transmission rate per unit time. Therefore, in this case, the airborne terminal will be connected to the mobile core network through the first link to achieve aviation communication.

[0079] For example, it is determined that the first available bandwidth BW1 allocated by the IMT base station to China Telecom, and it is also determined that the second available bandwidth BW2 allocated by the ATG base station to China Telecom.

[0080] If BW1 is greater than BW2, the airborne terminal is connected to the mobile core network via a first link consisting of an IMT base station and a terrestrial transmission network.

[0081] In step S230, if the first available bandwidth is smaller than the second available bandwidth, the mobile core network is accessed through the second link to implement aviation communication.

[0082] If the first available bandwidth is less than the second available bandwidth, it is proved that at this time, using the second link composed of the ATG base station and the ground transmission network to connect the airborne terminal to the mobile core network can obtain a higher data transmission rate per unit time. Therefore, in this case, the airborne terminal will be connected to the mobile core network through the second link to achieve aviation communication.

[0083] For example, it is determined that the first available bandwidth BW1 allocated by the IMT base station to China Telecom, and it is also determined that the second available bandwidth BW2 allocated by the ATG base station to China Telecom.

[0084] If BW1 is smaller than BW2, the airborne terminal is connected to the mobile core network via a second link consisting of an ATG base station and a ground transmission network.

[0085] In step S240, if the first available bandwidth is equal to the second available bandwidth, the mobile core network is accessed through the first link or the second link to achieve aviation communication.

[0086] If the first available bandwidth is equal to the second available bandwidth, it means that at this time, whether the airborne terminal is connected to the mobile core network through the first link or the airborne terminal is connected to the mobile core network through the second link, the data transmission amount obtained per unit time is the same. Therefore, the airborne terminal can be connected to the mobile core network through the first link or the second link to realize aviation communication.

[0087] For example, it is determined that the first available bandwidth BW1 allocated by the IMT base station to China Telecom, and it is also determined that the second available bandwidth BW2 allocated by the ATG base station to China Telecom.

[0088] If BW1 is equal to BW2, then the airborne terminal can be connected to the mobile core network through a first link consisting of an IMT base station and a terrestrial transmission network or through a second link consisting of an ATG base station and a terrestrial transmission network.

[0089] In this exemplary embodiment, if the first signal strength and the second signal strength are detected, the first available bandwidth can be compared with the second available bandwidth, and then based on the comparison result, a link combination suitable for the situation is determined, thereby improving the logic of determining a link combination suitable for the situation from different link combinations when the first signal and the second signal can be obtained.

[0090] In an alternative embodiment, Figure 3 FIG. 1 shows another flow chart of accessing a mobile core network through different link combinations in an aviation communication method, such as Figure 3 As shown, the method includes at least the following steps: in step S310, if only the second signal strength is detected and the second signal strength of the second signal transmitted to the ground transmission network is greater than the strength threshold, determine the third available bandwidth between the ground-to-air base station and the communication satellite and the fourth available bandwidth between the airborne terminal and the communication satellite.

[0091] Among them, since the main lobe of the ground IMT base station antenna is facing downward, and the main lobe of the ATG base station antenna is facing upward, when reaching a certain height, the first signal cannot be detected and only the second signal strength can be detected. Generally speaking, this situation occurs in some very remote areas.

[0092] It is worth mentioning that in remote areas, it is difficult for ATG base stations to directly access the mobile core network through the ground transmission network. Therefore, in order to ensure aviation mobile services, the mobile core network can be accessed through the ATG base station and communication satellite, the communication satellite and ground gateway station, the ground gateway station and the ground transmission network, or the mobile communication network can be accessed through the gateway station and the ground transmission network.

[0093] Because there are two ways to access the mobile core network, it is necessary to determine the third available bandwidth between the ATG base station and the communication satellite and the fourth available bandwidth between the airborne terminal and the communication satellite in order to determine one of the two ways for accessing the mobile core network.

[0094] For example, if only the second signal strength is detected and the second signal strength transmitted to the ground transmission network is greater than the strength threshold, but in remote areas, it is impossible to directly access the mobile core network through the ATG base station and the ground transmission network (second link), it is necessary to determine the third available bandwidth BW3 between the ATG base station and the Tiantong-1 satellite, and it is also necessary to determine the fourth available bandwidth BW4 between the airborne terminal and the Tiantong-1 satellite.

[0095] In step S320, if the third available bandwidth is greater than the fourth available bandwidth, the mobile core network is accessed through the third link to implement aviation communication.

[0096] Among them, if the third available bandwidth is greater than the fourth available bandwidth, the mobile core network can be accessed through a third link composed of ground-to-air base stations, communication satellites, ground gateways and ground transmission networks to obtain more data per unit time.

[0097] For example, a third available bandwidth BW3 between the ATG base station and the Tiantong-1 satellite is determined, and a fourth available bandwidth BW4 between the airborne terminal and the Tiantong-1 satellite is determined.

[0098] If BW3 is greater than BW4, the mobile core network can be accessed through the third link consisting of the ATG base station, Tiantong-1 satellite, ground gateway and ground transmission network.

[0099] In step S330, if the third available bandwidth is smaller than the fourth available bandwidth, the mobile core network is accessed through the fourth link to implement aviation communication.

[0100] Among them, if the third available bandwidth is smaller than the fourth available bandwidth, the mobile core network can be accessed through a fourth link consisting of a communication satellite, a ground gateway and a ground transmission network to obtain more data per unit time.

[0101] For example, a third available bandwidth BW3 between the ATG base station and the Tiantong-1 satellite is determined, and a fourth available bandwidth BW4 between the airborne terminal and the Tiantong-1 satellite is determined.

[0102] If BW3 is smaller than BW4, the mobile core network can be accessed through the fourth link consisting of the Tiantong-1 satellite, the ground gateway and the ground transmission network.

[0103] In step S340, if the third available bandwidth is equal to the fourth available bandwidth, access to the mobile core network is performed through the third link or the fourth link to implement aviation communication.

[0104] Among them, if the third available bandwidth is equal to the fourth available bandwidth, it proves that the data transmission amount obtained per unit time by accessing the mobile core network through the third link or the fourth link is the same. Therefore, the mobile core network can be accessed through the third link or through the fourth link.

[0105] For example, a third available bandwidth BW3 between the ATG base station and the Tiantong-1 satellite is determined, and a fourth available bandwidth BW4 between the airborne terminal and the Tiantong-1 satellite is determined.

[0106] If BW3 is equal to BW4, the ground transmission network can be accessed through the third link composed of ground-to-air base stations, communication satellites, ground gateways and ground transmission networks, or the mobile core network can be accessed through the fourth link composed of Tiantong-1 satellites, ground gateways and ground transmission networks.

[0107] In this exemplary embodiment, if only the second signal strength is detected and the second signal strength transmitted to the ground transmission network is greater than the strength threshold, the third available bandwidth and the fourth available bandwidth are determined. By comparing the third available bandwidth and the fourth available bandwidth, a suitable link combination is determined, thereby improving the logic of determining the link combination.

[0108] In an optional embodiment, if the target signal meets the link switching condition, access to the mobile core network is achieved through different link combinations of the target aviation mobile network to achieve aviation communication, including: if the first signal strength cannot be detected and the second signal strength cannot be detected, access to the mobile core network through a fourth link to achieve aviation communication.

[0109] When the aircraft flies to a non-land area, the first signal strength and the second signal strength cannot be detected, and the aircraft accesses the mobile core network through a fourth link composed of a communication satellite, a ground gateway, and a ground transmission network. The non-land area may be an ocean area or a river area, and this exemplary embodiment does not specifically limit this.

[0110] For example, when the aircraft flies over the ocean area, the first signal strength and the second signal strength cannot be detected at this time, and then the fourth link consisting of the Tiantong-1 satellite, the ground gateway station and the ground transmission network is used to access the mobile core network.

[0111] In this exemplary embodiment, if the first signal strength cannot be detected and the second signal strength cannot be detected, the mobile core network is accessed through the fourth link, which improves the logic of accessing the mobile core network and ensures the continuity of the aviation mobile service.

[0112] In the method and apparatus provided in the exemplary embodiments of the present disclosure, on the one hand, if the target signal meets the link switching condition, it accesses the mobile core network through different link combinations, thereby ensuring that when the target signal is in different situations, there are corresponding links that allow the airborne terminal to access the mobile core network, thereby ensuring the continuity of aviation communications and meeting the user's demand for mobile bandwidth access services on the aircraft; on the other hand, the target aviation network is jointly built by different operators, and different construction operators can share the target aviation mobile network, thereby realizing the co-construction and sharing of the target aviation mobile network and reducing the construction cost of the target aviation mobile network.

[0113] The aviation communication method in the embodiment of the present disclosure is described in detail below in conjunction with an application scenario.

[0114] Figure 4 The schematic diagram shows a flow chart of an aviation communication method in an application scenario, such as Figure 4 In the above, target 410 is a traveling aircraft, base station 420 is an ATG base station, base station 430 is an IMT base station, object 440 is a communication satellite, object 450 is a ground gateway, and network 460 is a mobile core network. It is worth noting that base station 420, base station 430, object 440, object 450 and network 460 constitute a target aviation mobile network, and the target aviation mobile network is jointly built and used by different carrier operators.

[0115] Dotted line 471 is the first link, dotted line 472 is the second link, dotted line 473 is the third link, dotted line 474 is the fourth link, solid line 475 represents the link between the ATG base station and the core mobile network, solid line 476 represents the link between the IMT base station and the core mobile network, and implementation 477 represents the link between the ground gateway and the core mobile network.

[0116] When the aircraft has just taken off or is about to land, the first link 471 can be used to connect the onboard terminal on the aircraft 410 to the mobile core network 460. When the aircraft rises to a certain altitude, the second link 472 can be used to connect the onboard terminal on the aircraft 410 to the mobile core network 460.

[0117] Correspondingly, when the aircraft descends from a certain altitude to a certain altitude, the second link 472 can be used to connect the airborne terminal on the aircraft 410 to the mobile core network 460. When the aircraft continues to descend and is about to land, the first link 471 can be used to connect the airborne terminal on the aircraft 410 to the mobile core network 460.

[0118] In addition, when the aircraft is flying over a remote area, one link can be selected from the third link 473 and the fourth link 474 to connect the onboard terminal on the aircraft 410 to the mobile core network 460. When the aircraft flies over a non-land area, the onboard terminal on the aircraft 410 can be connected to the mobile core network 460 through the fourth link 474.

[0119] In this application scenario, on the one hand, if the target signal meets the link switching conditions, it accesses the mobile core network through different link combinations, ensuring that when the target signal is in different situations, there are corresponding links that allow the airborne terminal to access the mobile core network, thereby ensuring the continuity of aviation communications and meeting the user's demand for mobile bandwidth access services on the aircraft; on the other hand, the target aviation network is jointly built by different operators, and different construction operators can share the target aviation mobile network, realizing the co-construction and sharing of the target aviation mobile network and reducing the construction cost of the target aviation mobile network.
