[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field based on the present invention belong to the scope of protection of the present invention.

[0034] The embodiment of the present invention provides a communication service providing method, see Figure 1 , which is a flow chart of a first communication service providing method provided in an embodiment of the present invention, and is applied to a satellite-borne core network element configured on a satellite. The method includes S101-S102.

[0035] S101, receiving an initial UE message sent by a satellite base station.

[0036] The initial UE message carries a UE type field, and the type field indicates the device type of the UE.

[0037] In S101, when the base station is set on a satellite, the base station is called a satellite base station. The initial UE message is generated in the following manner: when the UE initiates access to the satellite base station, the satellite base station identifies the device type of the UE, completes the access of the UE, and generates an initial UE message; wherein the initial UE message includes both the basic information of the UE and the type field (GATEWAY INDICATION) of the UE, and the type field indicates the device type of the UE determined by the satellite base station, that is, the determination result of the satellite base station determining whether the UE is a gateway.

[0038] There are many ways to express the determination result of whether the satellite base station determines that the UE is a gateway. For example, a logical value can be used to express the determination result of whether the satellite base station determines that the UE is a gateway. For example, the satellite base station determines that the UE is a gateway and uses "true (correct)" to express it, and the satellite base station determines that the UE is not a gateway and uses "false (error)" to express it. For example, if the satellite base station determines that the UE is a gateway, a field containing "true" is added to the initial UE message. If the satellite base station determines that the UE is not a gateway, a field containing "false" is added to the initial UE message. The satellite base station sends the initial UE message with the added field to the satellite core network element. In one possible case, the satellite base station can also use "true" to express that the UE is a gateway, and use other methods other than "true" to express that the satellite base station determines that the UE is not a gateway.

[0039] It should be noted that the logical value is only a method for expressing the determination result of whether the satellite base station determines whether the UE is a gateway. Other methods may also be used to express the determination result of whether the satellite base station determines whether the UE is a gateway, such as binary numbers, decimal numbers, English letters and other characters. The embodiment of the present invention does not limit the method for expressing the determination result of whether the satellite base station determines whether the UE is a gateway. In addition, the embodiment of the present invention does not limit the way in which the satellite base station identifies the device type of the UE.

[0040] See Table 1, which is an initial UE message table provided in an embodiment of the present invention. The first row in the table is a table header, including IE / Group Name, Presence, Range, IE type and reference, Semantics description, Criticality, and Assigned Criticality. The other data except the first and last rows represent the basic information of the UE, wherein Message Type represents the type of the initial UE message, and RAN UE NGAP ID (Radio Access Network User Equipment Next Generation Application Protocol Number) is used to uniquely identify the UE on the NG interface. RedCap Indication (Reduced capability Indication) is used to identify the RAT (Radio Access Technology) type of the UE. The last row of data in Table 1 indicates that the device type of the UE is a gateway or a user terminal, wherein GATEWAY INDICATION is the type field, and ENUMERATD (enumeration type) represents the data type of the data used by the satellite base station to determine whether the UE is a gateway. If the value of the type field is true, it means that the satellite base station determines that the UE is a gateway. If the value of the type field is not true, it means that the satellite base station determines that the UE is a user terminal. M indicates a required item, and O indicates that the item can be empty.

[0042]

[0043] In a possible embodiment, the satellite-borne core network element is an S-AMF (Satellite-Access and Mobility Management Function), and the S-AMF and the satellite-borne base station are configured on the same satellite.

[0044] See also Figure 2, which is a structural diagram of the first access and feed integrated system provided in an embodiment of the present invention. The above-mentioned access and feed integrated system includes a satellite base station, S-AMF, a user terminal, a gateway, a ground core network and a data network. The satellite base station and the S-AMF are configured on the same satellite, and the gateway and the user terminal are connected to the same satellite base station. Among them, the ground core network includes PCF (Policy Control function) network element, SMF (Session Management function) network element and UPF (The User plane function) network element.

[0045] Specifically, S-AMF supports integrated access and authentication functions for user terminals and gateways. The PCF network element is responsible for generating access and mobility management strategies, UE routing strategies, QoS (Quality of Service) rules and billing rules for user data transmission, etc., based on business information, user contract information, and operator configuration information. The SMF network element is responsible for tunnel maintenance, IP (Internet Protocol) address allocation and management, and has QoS control and billing functions. The UPF network element is responsible for managing user plane data transmission, traffic statistics, secure eavesdropping, and other functions. It should be noted that the above-mentioned network elements are only part of the network elements in the ground core network, which also includes other network elements.

[0046] It should be noted that Figure 2 The S-AMF in the system can also be an S-FC (Satellite-Feeder Controller, satellite-borne feed control functional network element).

[0047] By selecting the above embodiment and adopting an integrated access and feed design, the complexity of satellite equipment can be simplified, satellite costs can be reduced, and the time and frequency resource utilization of the satellite-to-ground link can be improved. The satellite core network element can identify the integrated access and feed gateway station and complete the access authentication of the gateway station.

[0048] In a possible embodiment, the onboard core network element is S-FC, and the onboard base stations include a first onboard base station configured on the same satellite as the S-FC and a second onboard base station configured on a different satellite from the S-FC. The first onboard base station is communicatively connected to the gateway station, the second onboard base station is communicatively connected to the user terminal, and the second onboard base station is communicatively connected to the first onboard base station via an inter-satellite link.

[0049] See also Figure 3, which is a structural diagram of the second access and feed integrated system provided in an embodiment of the present invention. The above-mentioned access and feed integrated system includes a first satellite base station, S-FC, a second satellite base station, a user terminal, a gateway station, a ground core network and a data network. The first satellite base station and S-FC are configured on the same satellite, and the second satellite base station and S-FC are configured on different satellites. The second satellite base station is connected to the first satellite base station through an inter-satellite link communication. The gateway station is connected to the first satellite base station, and the user terminal is connected to the second satellite base station. Among them, the ground core network includes AMF (Access and Mobility Management Function) network element, UDM (Unified Data Management) network element, PCF network element, AUSF (Authentication Server Function) network element, SMF network element and UPF network element, and S-FC is specifically responsible for handling the access problem of the gateway station. It should be noted that the above-mentioned network elements are only part of the network elements in the ground core network, and the ground core network also includes other network elements.

[0050] It should be noted that Figure 3 The S-FC in can also be S-AMF.

[0051] S102: Provide the UE with a communication service that matches the device type of the UE according to the type field in the initial UE message.

[0052] In S102, since the initial UE message includes both the basic information of the UE and the type field of the UE, the type field indicates the device type of the UE determined by the satellite base station, that is, the determination result of whether the UE is a gateway by the satellite base station, the satellite core network element can determine the device type of the UE based on the type field in the initial UE message.

[0053] Specifically, the type field is divided into a positive confirmation field and a non-positive confirmation field. Still taking the use of logical values ​​to represent the determination result of whether the satellite base station determines that the UE is a gateway as an example, if the satellite base station determines that the UE is a gateway, the type field is a positive confirmation field; if the satellite base station determines that the UE is not a gateway, the type field is a non-positive confirmation field. In other words, if the type field received by the satellite core network element is a positive confirmation field, the UE is determined to be a gateway. If the type field is a non-positive confirmation field, it means that the satellite base station determines that the UE is not a gateway. In this case, the satellite core network element determines that the UE is a user terminal.

[0054] If the onboard core network element determines that the UE is a gateway, it provides the UE with communication services that match the gateway, such as transmission backup, routing topology establishment, and flexible function deployment. If the onboard core network element determines that the UE is a user terminal, it provides the UE with communication services that match the user terminal, such as network communication services.

[0055] By selecting the above embodiment, since the initial UE message carries a type field indicating the device type of the UE, when the onboard core network network element configured on the satellite receives the initial UE message sent by the onboard base station, it can determine the device type of the UE based on the type field in the initial UE message and provide the UE with a communication service that matches the device type of the UE, thereby solving the problem that it is difficult for the onboard core network network element to provide the UE with a matching communication service.

[0056] In order to more clearly explain the above communication service providing method, Figure 4 For a detailed description of the above communication service provision method, see Figure 4 , is a flow chart of a second communication service providing method provided by an embodiment of the invention, the method comprising:

[0060] The type field indicates the device type of the UE.

[0062] Among them, when the device type of the UE is a gateway station, the onboard core network element provides the UE with communication services matching the gateway station; when the device type of the UE is a user terminal, the onboard core network element provides the UE with communication services matching the user terminal.
