The following first introduces the contents involved in the solution provided by the embodiment of the present disclosure.

Under the vision of providing users with ubiquitous communications, remote areas, disaster-stricken areas, and other areas where it is difficult to deploy base stations, gateways, and other equipment can achieve information exchange through satellites. Specifically, deploying base stations on satellites can reduce the cost requirements for deploying satellites on the ground; but since the deployment of gateways is also limited, the satellite may not be able to connect to the gateway in time when it is in the air, so the data may not be immediately transmitted back to the core network; in this case, for terminals that do not require high data latency, it is possible to tolerate data storage on the satellite, and then transmit it after the satellite is connected to the gateway. In addition, due to the limited equipment resources on the satellite, additional contracts are required before users can use this service. Based on this, this solution proposes a method to support terminals to use on-board base stations or on-board storage and forwarding services, so that terminal users can use on-board services. Services for communication.

Among them: the ephemeris is a table of stellar orbital parameters, that is, the table data is used to describe the scheduled position (orbital trajectory information or coordinates) of a stellar body at regular intervals, or the scheduled position (orbital trajectory information or coordinates) of a man-made satellite at regular intervals;

There are currently two formats for ephemeris information, as follows:

Format 1: Satellite position and vector velocity;

Format 2: semi-major axis; eccentricity; pericentric parameter; longitude of ascending node; inclination; average anomaly over epoch time.

The following is a detailed introduction to the relevant content.

(1) Scenarios where data needs to be stored and forwarded on the satellite;

In the current demand research, some research institutions may need to study the living habits and movement trajectories of animals; some departments may need to make timely warnings to reduce or avoid the occurrence of disasters, such as the detection of submarine cables; for these Internet of Things (IOT) deployed on animals or equipment, due to their geographical location in special or remote areas, where there are no communication base stations, data transmission is required via satellite communication. Specifically, since these scenarios do not require high latency, and these places may not necessarily have gateways deployed, the data can be uploaded to the satellite first, stored on the satellite (there may be base stations or core network elements on the satellite), and then forwarded when the satellite can access the gateway, as shown in Figure 2.

(ii) the implementation architecture of store-and-forward on satellites;

In order to support the above scenarios, base stations or some core network elements need to be deployed on satellites, as shown in Figure 3. In Figure 3, the data of the terminal or ship can be transmitted back to the local gateway station to the core network through the satellite, or back to the remote gateway station to the core network through the inter-satellite link. In Figure 3, ISL means inter-satellite link, Feeder Link means feeder link, and DC means data center.

(III) Satellite Internet is a new type of communication network that combines satellite communications with information networks such as the Internet. It is an information network infrastructure that uses high, medium and low-orbit broadband satellites to provide global real-time, seamless broadband Internet services to various users on land, sea and sky. Satellite Internet complements the ground-based 5G network and ground-based Internet to achieve the goal of providing information at your fingertips and everything at your fingertips. In the process of building satellite Internet, the deep integration of heaven and earth is the core goal of the system. The role of heaven and earth integration will be reflected in "complementary advantages, business transparency, network universality, technology reference, and industry collaboration".

The following table briefly introduces several typical non-terrestrial networks (NTN):

(iv) Cellular Internet of Things (CIoT);

The control plane CIoT 5GS is optimized for exchanging user data between the UE and the Session Management Function (SMF) as a contactless communication interface in the uplink and downlink directions. The UE and the Access and Mobility Management Function (AMF) perform integrity protection and encryption on user data by using NAS PDU integrity protection and encryption. For Internet Protocol (IP) and Ethernet data, the UE and SMF can negotiate and perform header compression.

Specifically, the UE and AMF negotiate to support and use the control plane CIoT 5GS optimization. When the control plane CIoT 5GS optimization function is used and the PDU session type is unstructured, the SMF selects the Network Exposure Function (NEF) or the User Plane Function (UPF) based on the UE contract information.

During the PDU session establishment process, AMF indicates to SMF that control plane CIoT 5GS optimization is available for data transmission.

The information transmission method provided in the embodiment of the present disclosure is illustrated below by taking the radio access network RAN (base station) as an example of the first on-board network device, and taking the access and mobility management function AMF as an example of the second on-board network device.

In view of the above technical problems, the embodiments of the present disclosure provide an information transmission method, which can be specifically implemented as a method for activating an on-board store-and-forward mechanism. The architecture for implementing the method may include the following:

Architecture 1: As shown in Figure 7, a lightweight 5G core network (5G Core Network, 5GC) (AMF+SMF+UDM+UPF) + gNB are deployed on the same satellite; among them, Feeder Link represents feeder link and DN represents data network.

Architecture 2: As shown in Figure 8, base stations + UPF are deployed on low-orbit satellites, and lightweight 5GC (AMF + SMF + UDM) is deployed on high-orbit satellites.

Under the above two architectures, it can be: UDM stores contract information, data is temporarily stored in UPF, or storage equipment is added and installed together with the base station. The two architectures have the same scheme for activating the storage and forwarding mechanism and PDU transmission. GEO in Figure 8 represents geosynchronous satellite, which can also be called high-orbit satellite.

The following is a specific example to illustrate this solution.

Example 1: The terminal requests the on-board store-and-forward service during the registration process and activates the store-and-forward service. The AMF needs to confirm whether the on-board store-and-forward service is supported and the negotiation results of various parameters. As shown in Figure 9, the steps are as follows:

1. When the UE hopes that the onboard base station will serve it, it sends a registration request to the onboard RAN (i.e., the base station), and the request includes an onboard store-and-forward service request (corresponding to the above-mentioned terminal sending an onboard store-and-forward service request to the first onboard network device). In some embodiments, it includes one or a combination of parameters such as the data validity period supported by the terminal, the transmission time window, the data failure processing method (such as retransmission or discarding), and the data sending method preference (such as using the user plane (User Plane, UP) (PDU) or small data). 2. The onboard RAN forwards the request to the AMF (corresponding to the above-mentioned receiving the onboard store-and-forward service request sent by the terminal; sending the onboard store-and-forward service request to the second onboard network device). In some embodiments, it includes one or a combination of parameters such as the data validity period supported by the (terminal), the transmission time window, the data failure processing method (such as retransmission or discarding), and the data sending method preference (such as using UP (PDU) or small data).

3.AMF obtains the UE's subscription information about the on-board store-and-forward service from UDM (i.e. on-board service Contract information).

4.AMF confirms whether the on-board storage and forwarding service request requested by the terminal is supported based on one or a combination of parameters such as contract information, on-board memory information (which can be obtained from SMF or base station), service priority (reported by the terminal), network capability (which the AMF itself has), and the number of user requests (which the AMF itself has). (Corresponding to the above-mentioned confirmation of whether the on-board storage and forwarding service of the target terminal is supported based on the third information.

5.AMF obtains ephemeris information from the third-party AF and/or NEF and/or OAM and/or NWDAF, obtains UE mobility information from NWDAF, and confirms the UE unreachable time (i.e., transmission time window).

6.AMF confirms one or a combination of parameters such as the transmission time window, the effective time of the stored data life cycle (i.e., the data effective time), the buffer size (Buffer size) (corresponding to the on-board memory information), the data failure processing method (such as retransmission or discarding), and the data sending method preference (such as using UP (PDU) or small data) based on the storage device memory information (i.e., the on-board memory information mentioned above), the number of terminals (corresponding to the number of user requests mentioned above), the ephemeris information, the business volume (which can be obtained based on the number of user requests mentioned above), and the supported data effective time reported by the terminal (corresponding to the above-mentioned determination of the on-board service reference information for the target terminal based on the fifth information).

Among them, due to limited or insufficient available memory, the satellite is out of coverage, the number of terminals is large, etc., if the transmission cannot be completed within a certain period of time, the satellite needs to delete some data regularly, so the data validity period is informed to the UE. After the UE knows it, it will retransmit or accept the discard operation.

7. If the request is confirmed to be supported, the AMF returns a registration acceptance response to the RAN (corresponding to the sending of the on-board service reference information to the first on-board network device corresponding to the target terminal). The acceptance response may include: data validity time, UE unreachable time (transmission time window), and in some embodiments, on-board memory information - Buffer size, data failure processing method (such as retransmission or discard), data sending method (that is, the negotiation result of the data sending method, such as using UP (PDU) or small data) and other parameters or a combination thereof. Otherwise (that is, it is confirmed that the request is not supported), the rejection reason value is carried.

8. The onboard RAN sends a registration acceptance response (which may include valid time of the data carried, UE unreachable time (transmission time window), and in some embodiments, may also include onboard memory information-Buffer size, data failure processing method (such as retransmission or discard), data transmission method (such as using UP (PDU) or small data) and other parameters or a combination thereof) to the UE (corresponding to the above-mentioned use of the onboard service reference information as parameter information of the onboard store-and-forward service for the target terminal; sending the reference information to the target terminal); The on-board memory information may specifically be an on-board storage space allowed to be used by the UE.

Example 2: The terminal requests the on-board store-and-forward service during the registration process; the base station confirms the negotiation results of various parameters, as shown in FIG. 10, including the following steps:

1. When the UE hopes that the onboard base station will serve it, it sends a registration request to the onboard RAN, where the request includes an onboard store-and-forward service request (corresponding to the above-mentioned terminal sending an onboard store-and-forward service request to the first onboard network device). In some embodiments, it includes one or a combination of parameters such as supported data validity time, transmission time window, data failure processing method (such as retransmission or discard), and data transmission method preference (such as using UP (PDU) or small data).

2. The on-board RAN forwards the request to the AMF (corresponding to the above-mentioned receiving the on-board store-and-forward service request sent by the terminal; sending the on-board store-and-forward service request to the second on-board network device). In some embodiments, it includes one or a combination of parameters such as the data validity time supported by the (terminal), the transmission time window, the data failure processing method (such as retransmission or discard), and the data sending method preference (such as using UP (PDU) or small data).

3.AMF obtains the UE's contract information about the on-board store-and-forward service (i.e., on-board service contract information) from UDM.

4. AMF confirms whether the on-board storage and forwarding service request requested by the terminal is supported based on one or a combination of parameters such as contract information, on-board memory information, service priority, network capability, number of user requests (AMF itself has), etc. (corresponding to the above-mentioned confirmation of whether the on-board storage and forwarding service of the target terminal is supported based on the third information).

5. If the request is confirmed to be supported, the AMF returns a registration acceptance request to the RAN (corresponding to sending the on-board service reference information to the first on-board network device corresponding to the target terminal); the acceptance request may include on-board memory information and ephemeris information (which the AMF can obtain by itself), corresponding to the fourth information obtained above, as the on-board service reference information for the target terminal. Otherwise, it carries the reason value for rejection.

6. The RAN receives the registration acceptance request and confirms one or a combination of parameters such as a transmission time window, a storage data life cycle validity period, a buffer size, a data failure processing method (such as retransmission or discarding), and a data sending method (such as using UP (PDU) or small data) based on one or a combination of parameters such as the storage device memory information (i.e., the above-mentioned on-board memory information), the number of terminals, the ephemeris information, the service volume, and the supported data validity period reported by the terminal (corresponding to the above-mentioned determination of the parameter information of the on-board storage and forwarding service for the target terminal based on the on-board service reference information and the first information).

Among them, due to limited or insufficient available memory, the satellite is out of coverage, the number of terminals is large, etc., if the transmission cannot be completed within a certain period of time, the satellite needs to delete some data regularly, so the data validity period is informed to the UE. After the UE knows it, it will retransmit or accept the discard operation.

7. The onboard base station sends a registration acceptance response (which may include valid time of the portable data, UE unreachable time (transmission time window), and in some embodiments, may also include onboard memory information - buffer size, data failure processing method (such as retransmission or discard), data transmission method (such as using UP (PDU) or small data) and other parameters or a combination thereof) to the UE (corresponding to the above-mentioned sending of the parameter information to the target terminal). The onboard memory information may specifically be the onboard storage space allowed to be used by the UE.
