In order to facilitate understanding of the technical solutions of the present invention, the following briefly introduces terms related to the present invention.

1. Ground-to-air broadband wireless communication technology

The ground-air broadband refers to that an airplane flying at a cruising altitude (9000-10000 meters) can communicate with a ground wireless communication base station, and then converts wireless communication signals into Wi-Fi signals for passengers in an airplane cabin to use and finish ground-air data communication interaction. The ground-to-air broadband wireless communication technology can theoretically realize stable broadband communication service of more than 10M. Based on the above, the ground-to-air broadband wireless communication technology can provide internet access for passengers on the airplane, and services such as Internet Protocol Television (IPTV) and video on demand based on broadband internet.

2. 5G non-independent networking mode (5GNSA)

The 5G non-independent networking mode refers to the fact that the existing 4G infrastructure is used for deployment of a 5G network. The 5G carrier based on the NSA architecture carries only user data, and its control signaling is still transmitted through the 4G network.

3. Access Point Name (Access Point Name, APN)

The APN is a parameter that must be configured when the terminal accesses the internet, and is used for determining the access mode of the terminal accessing the network.

4. Quality of Service (Quality of Service, QoS)

QoS refers to a network that can provide better service capability for a given network communication using various basic technologies, and is a security mechanism of the network, which is a technology for solving the problems of network delay and congestion.

5. QoS Class Identifier (QoS Class Identifier, QCI)

QCI is a metric value used to measure the packet forwarding behavior, such as packet loss Rate and packet delay budget, of a specific Service data stream SDF (SDF), which is applied to both Guaranteed Bit Rate (GBR) and Non-Guaranteed Bit Rate (Non-GBR) bearers, and is used to specify the control bearer level packet forwarding modes defined in the access node, such as scheduling weight, admission threshold, queue management threshold, link layer protocol configuration, etc., which are pre-configured by the operator to the access network node.

6. Mobile Edge Computing (MEC)

Mobile Edge Computing (MEC) can provide services required by IT and cloud Computing functions of telecommunication users nearby by using a wireless access network, thereby creating a telecommunication-level service environment with high performance, low delay and high bandwidth, accelerating the rapid downloading of various contents, services and applications in the network, and enabling consumers to enjoy uninterrupted high-quality network experience.

The above is an introduction of terms related to the embodiments of the present invention, and the details are not described below.

The technical scheme provided by the embodiment of the invention can be applied to various ground-air communication systems, such as a 5G communication system, a future evolution system or a plurality of communication fusion systems and the like.

In addition, the network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not constitute a limitation to the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

As shown in fig. 1, it is an architecture of a ground-air communication network to which the technical solution provided by the embodiment of the present invention is applied. The ground-to-air communication network may include: the system comprises an aircraft terminal, a Base Station (BS), a core network gateway, an MEC gateway and a PCRF.

In embodiments of the present invention, the ground-to-air communication network may provide services to aircraft before takeoff, in flight, and after landing. That is, the service area of the ground-to-air communication network may cover the entire route of the aircraft.

The base stations may include various forms of base stations, such as: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, etc. The method specifically comprises the following steps: the base Station may be an Access Point (AP) in a Wireless Local Area Network (WLAN), a base Station (BTS) in a Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), a base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA), an Evolved Node B (eNB, eNodeB) in LTE, or a relay Station or Access point, or a base Station in a vehicle-mounted device, a wearable device, and a Next Generation Node B (The Next Generation Node B, gbb) in a future 5G Network, or a base Station in a future Evolved Public Land Mobile Network (PLMN) Network.

In the embodiment of the invention, the base stations are arranged on the whole route of the airplane at intervals so as to provide service for the airplane terminals by the base stations.

The aircraft terminal may be an aircraft sensor device and a common terminal on an aircraft. (1) Aircraft sensor devices are used to monitor the operating state of an aircraft. The aircraft sensor device may be, for example, an engine sensor device, a pitot tube, an elevation sensor, an altitude gauge. (2) For example, the common terminal may be a mobile phone (mobile phone), a tablet computer, or a computer with wireless transceiving function. The airplane terminal may also be a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in an unmanned aerial vehicle, a wireless terminal in telemedicine on the airplane, and so on.

In the embodiment of the invention, in order to enable the aircraft sensor device to communicate with the base station on the ground, the aircraft sensor device is provided with the SIM card. Meanwhile, in order to distinguish the airplane sensor device from the common terminal, the APN in the SIM card configured by the airplane sensor device is different from the APN in the SIM card configured by the common terminal. Therefore, the network side can determine whether the airplane terminal is an airplane sensor device or a common terminal according to the APN carried by the message sent by the airplane terminal.

It should be noted that, in order to ensure high reliability and low latency of data of the aircraft sensor device, a network side needs to adopt a high-priority bearer to be responsible for transmitting the data of the aircraft sensor device, and therefore an APN in a SIM card configured by the aircraft sensor device is a first APN. The first APN may also be referred to as a dedicated APN, and the embodiments of the present invention are not limited thereto.

Correspondingly, compared with the data of the airplane sensor device, the network side may adopt a bearer with a relatively lower priority to be responsible for transmitting the data of the airplane sensor device, so that the APN in the SIM card configured by the normal terminal is the second APN. The second APN may be referred to as a common APN, and the embodiments of the present invention are not limited thereto.

A Charging rule Function (PCRF) is a Policy and Charging control Policy decision point for traffic data flows and IP bearer resources. In the embodiment of the invention, the PCRF configures different QoS strategies for the aircraft sensor equipment and the common terminal. The QoS strategy configured by the PCRF for the aircraft sensor equipment is as follows: the data of the aircraft sensor devices is transmitted to a local server (or local cloud) through the MEC gateway. The QoS policy configured by the PCRF for the common terminal is: the data of the common terminal is transmitted to the external network (namely, the data network) through the gateway of the core network.

In practical application, for the purpose of configuring different QoS policies for different devices (e.g., an airplane sensor device and a common terminal), the PCRF sets a correspondence between the APN and the QCI. For example, the correspondence between the APN and the QCI may be: the first APN corresponds to a first QCI, and the second APN corresponds to a second QCI.

The MEC gateway is used for transmitting data of the aircraft sensor equipment. Each base station on the aircraft route deploys a respective one of the MEC gateways.

The core network gateway is used for transmitting data of the common terminal.

It will be appreciated that each base station on an aircraft route is configured with an IP address of a core network gateway and an IP address of a corresponding MEC gateway.

The ground-air communication method provided by the embodiment of the invention is described below with reference to the communication system shown in fig. 1.

As shown in fig. 2, an embodiment of the present invention provides a ground-to-air communication method, which may include S101-S108:

s101, the ground base station receives a data service request message sent by a terminal on the airplane.

The data service request message is used for requesting to perform a data service. The data service request message includes an APN.

S102, the ground base station sends a QoS configuration request message to the PCRF.

Wherein the QoS configuration request message comprises an APN.

It is understood that the APN included in the QoS configuration request message is the same as the APN included in the data service request message.

S103, the PCRF determines the QCI corresponding to the APN according to the APN.

As a possible implementation manner, the PCRF determines the QCI corresponding to the APN according to a pre-established correspondence between the APN and the QCI and the APN included in the QoS configuration request message.

In the embodiment of the present invention, the correspondence between the APN and the QCI includes: the first APN corresponds to a first QCI, and the second APN corresponds to a second QCI.

The first APN is an APN used by the airplane sensor equipment. The second APN is an APN used by a common terminal.

In an embodiment of the invention, the first QCI is smaller than the second QCI. Illustratively, the first QCI may be 1 or 5 and the second QCI may be 9.

S104, the PCRF sends a QoS configuration response message to the ground base station.

And the QoS configuration response message comprises the QCI corresponding to the APN.

Optionally, the QoS configuration response message further includes: and the corresponding relation information is used for indicating the corresponding relation between the QCI and the target IP address.

In this embodiment of the present invention, the target IP address corresponding to the first QCI is an IP address of an MEC gateway connected to the ground base station. The target IP address corresponding to the second QCI is the IP address of the core network gateway connected with the ground base station.

And S105, the ground base station judges whether the data service of the terminal is the data service of the airplane sensor equipment or not according to the QCI corresponding to the APN.

In the embodiment of the present invention, when the QCI corresponding to the APN is the first QCI, it indicates that the terminal is the aircraft sensor device, and correspondingly, the data service of the terminal is the aircraft sensor device data service. When the QCI corresponding to the APN is the second QCI, the terminal is indicated to be a common terminal, and correspondingly, the data service of the terminal is a common terminal data service.

Wherein, in case that the data service of the terminal is the data service of the aircraft sensor device, the ground base station performs the following step S106. In case that the data service of the terminal is a general terminal data service, the terrestrial base station performs the following step S107.

And S106, the ground base station sends the data packet of the data service of the aircraft sensor equipment to the MEC gateway.

As a possible implementation manner, the ground base station determines the IP address of the MEC gateway according to the QCI corresponding to the APN and the corresponding relationship information. And after the data packet of the data service of the aircraft sensor equipment reaches the ground base station, the ground base station sends the data packet to the MEC gateway according to the IP address of the MEC gateway.

It should be noted that the MEC gateway serves as a gateway for data return and shunt of the aircraft sensor device, and is in butt joint with the local server. After receiving the data packet, the MEC gateway forwards the data packet to the local server. It can be understood that, compared with an external network server, the local server only has an internal network access right, the right is high, and the security is stronger.

And after receiving the data of the airplane sensor equipment, the local server carries out local processing and sends the data to the aviation safety application platform. The aviation safety application platform is used for managing various data of the airplane sensor device. The data of the airplane sensor equipment can be checked by the staff in the airport through the aviation safety application platform, so that the equipment running state in the airplane flying process can be mastered at any time, and real-time adjustment and operation implementation are carried out.

And S107, the ground base station sends the data packet of the common terminal data service to the core network gateway.

Illustratively, the core network Gateway may be a Data Gateway (DGW) in the core network.

As a possible implementation manner, the ground base station determines an IP address of the core network gateway according to the QCI corresponding to the APN and the corresponding relationship information. After the data packet of the common terminal data service reaches the ground base station, the ground base station sends the data packet to the core network gateway according to the IP address of the core network gateway.

It is understood that after receiving the data packet of the general terminal data service, the core network gateway forwards the data packet to an external network (such as the internet) to realize the information interaction of the ground-air data communication completed by passengers in the aircraft cabin by using the general terminal. Based on the method, passengers in the airplane cabin can realize internet access by realizing a common terminal and use services such as Internet Protocol Television (IPTV) based on broadband internet, video on demand and the like.

Based on the technical scheme provided by the invention, as the APN configured by the common terminal is different from the APN configured by the airplane sensor equipment, the network side can allocate different QCIs for the common terminal and the airplane sensor equipment. Therefore, the ground base station can determine whether the airplane terminal is the airplane sensor device or the common terminal according to the QCI of the airplane terminal. Furthermore, the ground base station can send the data of the aircraft sensor equipment to the MEC gateway so as to ensure the requirements of the aircraft sensor equipment on high safety, high reliability and low time delay.

In the embodiment of the present invention, the base station may be divided into the functional modules or the functional units according to the above method examples, for example, each functional module or functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module may be implemented in a form of hardware, or may be implemented in a form of a software functional module or a functional unit. The division of the modules or units in the embodiments of the present invention is schematic, and is only a logic function division, and there may be another division manner in actual implementation.
