[0002] A non-terrestrial network (NTN) communication system refers to a system that realizes new radio (NR) communication through movable platforms such as satellites or unmanned aerial vehicles. In places where terrestrial network devices cannot be popularized, NTN coverage can be adopted to further improve the coverage range. The current NTN communication systems can include NTN communication systems based on transparent payload and NTN communication systems based on regenerative payload. Under different NTN communication systems, the access methods of terminals are different, and the backhaul links under different access methods are also different.

[0061] Figure 2A block diagram of an NTN communication system to which embodiments of the present application can be applied is shown. The NTN communication system includes a terminal 11, a satellite (or a movable platform such as a drone) 22, and a terrestrial gateway 23. The link between the terminal 11 and the satellite 22 is called a service link (i.e., service link), and the link between the satellite 22 and the terrestrial gateway 23 is called a feeder link (i.e., feeder link). In some scenarios (such as low-earth orbit satellites LEO), due to satellite movement, switching of the service link or the feeder link will occur. For service link switching, the serving satellite of all terminals in the cell needs to be switched from one satellite to another satellite. For feeder link switching, a certain satellite needs to be switched from one terrestrial gateway to another terrestrial gateway.

For example, the network-side device, or some hardware or functions in the network-side device are located on a satellite, or are located on other movable devices (such as various mobile vehicles such as cars, airplanes, drones, ships, etc.). In the following, the case where the network-side device, or some hardware or functions in the network-side device are located on a satellite is taken as an example for introduction, but it can be understood that the movable device is not limited to a satellite and can also be other types of devices as described above.

[0063] The information processing method and the network-side device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0064] As Figure 3 shown, the embodiments of the present application provide an information processing method 300. This information processing method can be executed by a first device. In other words, this information processing method can be executed by software or hardware installed in the first device. The information processing method includes the following steps.

[0065] S302: The first device obtains first configuration information or access information, and the access information includes access information of the regenerative access mode.

[0066] In an NTN communication system, when a terminal is already connected, a first device can obtain first configuration information and access information. Herein, the first device can be an AMF or an MME.

[0067] The first configuration information can be the local configuration information of the first device. When obtaining the first configuration information, the first device can obtain the first configuration information from local. Optionally, in some embodiments, the first configuration information can be used to indicate (or can include) at least one of the following:

[0068] A second mapping relationship between a Radio Access Network ID (RAN ID) and a backhaul type, where the backhaul type includes the backhaul type of the regenerative access mode;

[0069] A third mapping relationship between a Tracking Area ID (TAI) and a backhaul type, where the backhaul type includes the backhaul type of the regenerative access mode.

[0070] The access information can include the access information of the regenerative access mode. Optionally, in some embodiments, the access information can include a first piece of information or a second piece of information. Among them, the first piece of information is used to indicate that the terminal accesses through the regenerative access mode, and the second piece of information is used to indicate whether there is participation of Inter-Satellite Links (ISL) in the regenerative access mode or the participation information in the case of ISL participation.

[0071] The above regenerative access mode can include at least one of the following:

[0072] Access through the regenerative access mode via a Geostationary Earth Orbit (GEO) satellite;

[0073] Access through the regenerative access mode via a Medium earth orbit (MEO) satellite;

[0074] Access through the regenerative access mode via a Low Earth Orbit (LEO) satellite;

[0075] Access through the regenerative access mode via other types of satellites (othersat).

[0076] Among them, the base station type that can represent a non-terrestrial base station by accessing through the regenerative access method of GEO is the high-orbit regenerative load type. The base station type that can represent a non-terrestrial base station by accessing through the regenerative access method of MEO is the medium-orbit regenerative load type. The base station type that can represent a non-terrestrial base station by accessing through the regenerative access method of LEO is the low-orbit regenerative load type. The base station type that can represent a non-terrestrial base station by accessing through the regenerative access method of other types of satellites is the other type of regenerative load type.

[0077] It should be noted that in a Narrow Band Internet of Things (NB-IoT) communication system, the base station type of a non-terrestrial base station can also be the following types:

[0078] NB-IOT regenerative payload type;

[0079] NB-IOT store and forward (S&F) type;

[0080] NB-IOT high-orbit regenerative load type;

[0081] NB-IOT medium-orbit regenerative load type;

[0082] NB-IOT low-orbit regenerative load type;

[0083] NB-IOT high-orbit store and forward type;

[0084] NB-IOT medium-orbit store and forward type;

[0085] NB-IOT low-orbit store and forward type.

[0086] It should also be noted that the regenerative access method can also be referred to as the regenerative access type, or the regenerative load type.

[0087] The above participation information may include at least one of the following:

[0088] The number of hops of the ISL;

[0089] The delay of the ISL.

[0090] When the first device obtains access information, it can obtain access information according to local configuration information or obtain access from other devices. Optionally, in some embodiments, when the access information includes the first information, the first device obtaining access information may include:

[0091] The first device receives the access information sent by the second device.

[0092] The second device can be the RAN.

[0093] Optionally, in some embodiments, when the access information includes second information, the first device obtaining the access information may include at least one of the following:

[0094] The first device receives the access information sent by the second device;

[0095] The first device determines the access information according to the second configuration information.

[0096] The second configuration information may be the local configuration information of the first device. Optionally, the second configuration information may be used to indicate (or may include) a first mapping relationship between the TAI and the second information. When the first device determines the access information according to the second configuration information, it may determine the access information according to this first mapping relationship. For example, there is a first mapping relationship between TAI#1 and ISL being two hops or the delay being 6 ms. Then, when the first device determines the access information, it may determine that the second information in the access information is ISL with two hops or the delay is 6 ms according to TAI#1.

[0097] Optionally, in some embodiments, when the first device (AMF) receives the access information of the regenerative access mode of the second device (RAN), it may also determine mobility restrictions according to the access information of the regenerative access mode, that is, the radio access technology restriction information (RAT) of the terminal in the regenerative access mode, the Forbidden Area, the Service Area Restriction, the core network type restriction, etc. Among them:

[0098] Forbidden Area: The terminal is prohibited from accessing in this area, and the terminal cannot send any messages to the network-side device.

[0099] RAT Restriction: Defines the RAT types that the terminal cannot access.

[0100] Service Area Restriction: Divided into Allowed Area and Non Allowed Area. The terminal can normally access the network-side device in the Allowed Area, and can initiate periodic updates and registration requests in the Non Allowed Area, but cannot initiate SR and any session-related signaling.

[0101] Optionally, the first device will also send the determined radio access technology restriction information (RAT) in the regenerative access mode, the Forbidden Area, the Service Area Restriction, and the core network type restriction to the second device (RAN) or the terminal.

[0102] S304: The first device determines the backhaul type according to the first configuration information or the access information, and the backhaul type includes the backhaul type of the regenerative access mode.

[0103] After obtaining the first configuration information and the access information, the first device can determine the backhaul type according to the first configuration information or the access information, and the backhaul type includes the backhaul type of the regenerative access mode. Among them, the backhaul type of the regenerative access mode can be expressed as the regenerative satellite backhaul type.

[0104] As described in S302, the first configuration information may include at least one of the second mapping relationship between the RAN ID and the backhaul type and the third mapping relationship between the TAI and the backhaul type. Then, when the first device determines the backhaul type according to the first configuration information, optionally, it may include at least one of the following:

[0105] The first device determines the backhaul type according to the second mapping relationship;

[0106] The first device determines the backhaul type according to the third mapping relationship.

[0107] For example, there is a second mapping relationship between RAN ID #1 and the LEO regenerative satellite backhaul type. Then, when the first device determines the backhaul type according to the second mapping relationship, it can determine that the backhaul type of the current terminal is the LEO regenerative satellite backhaul type according to RAN ID #1.

[0108] For another example, there is a third mapping relationship between TAI #1 and the LEO regenerative satellite backhaul type. Then, when the first device determines the backhaul type according to the third mapping relationship, it can determine that the backhaul type of the current terminal is the LEO regenerative satellite backhaul type according to TAI #1.

[0109] As described in S302, the access information may include the first information or the second information. The first information is used to indicate that the terminal accesses through the regenerative access mode, and the second information is used to indicate whether there is participation of the ISL in the regenerative access mode or the participation information in the case of participation of the ISL. Then, when the first device determines the backhaul type according to the access information, in the case where the access information includes the first information, optionally, it may include at least one of the following:

[0110] When the first information indicates that the terminal accesses through the regenerative access mode of GEO, determine that the backhaul type is the backhaul type through the regenerative access mode of GEO;

[0111] When the first information indicates that the terminal accesses through the regenerative access mode of MEO, determine that the backhaul type is the backhaul type through the regenerative access mode of MEO;

[0112] When the first information indicates that the terminal accesses through the regenerative access mode of LEO, determine that the backhaul type is the backhaul type through the regenerative access mode of LEO;

[0113] When the first information indicates that the terminal accesses through the regenerative access mode of other types of satellites, determine that the backhaul type is the backhaul type through the regenerative access mode of other types of satellites.

[0114] The backhaul type through the regenerative access mode of GEO can be expressed as GEO regenerative satellite backhaul, the backhaul type through the regenerative access mode of MEO can be expressed as MEO regenerative satellite backhaul, the backhaul type through the regenerative access mode of LEO can be expressed as LEO regenerative satellite backhaul, and the backhaul type through the regenerative access mode of other types of satellites can be expressed as other regenerative satellite backhaul.

[0115] When the access information includes the first information and the second information, optionally, when the first device determines the backhaul type according to the access information, it may include at least one of the following:

[0116] When the first information indicates that the terminal accesses through the regenerative access mode of GEO, determine that the backhaul type is the dynamic backhaul type through the regenerative access mode of GEO;

[0117] When the first information indicates that the terminal accesses through the regenerative access mode of MEO, determine that the backhaul type is the dynamic backhaul type through the regenerative access mode of MEO;

[0118] When the first information indicates that the terminal accesses through the regenerative access mode of LEO, determine that the backhaul type is the dynamic backhaul type through the regenerative access mode of LEO;

[0119] When the first information indicates that the terminal accesses through the regenerative access mode of other types of satellites, determine that the backhaul type is the dynamic backhaul type through the regenerative access mode of other types of satellites.

[0120] The dynamic backhaul type of the regenerative access mode via GEO can be expressed as DYNAMIC GEO regenerative satellite backhaul, and the backhaul link changes dynamically, such as whether there is an ISL involved. The dynamic backhaul type of the regenerative access mode via MEO can be expressed as DYNAMIC MEO regenerative satellite backhaul, and the backhaul link changes dynamically, such as whether there is an ISL involved. The dynamic backhaul type of the regenerative access mode via LEO can be expressed as DYNAMIC LEO regenerative satellite backhaul, and the backhaul link changes dynamically, such as whether there is an ISL involved. The dynamic backhaul type of the regenerative access mode via other types of satellites can be expressed as DYNAMIC other regenerative satellite backhaul, and the backhaul link changes dynamically, such as whether there is an ISL involved.

[0121] Optionally, in some embodiments, after determining the backhaul type of the regenerative access mode, the first device may perform at least one of the following operations:

[0122] The first device sends the access information or the information of the backhaul type to the third device;

[0123] The first device sends the access information or the information of the backhaul type to the fourth device.

[0124] The third device may be an SMF. The fourth device may be a PCF. The information of the backhaul type may indicate the backhaul type of the regenerative access mode. After the first device sends the access information or the information of the backhaul type to the third device, the third device may determine the first Quality of Service (QoS) parameter according to the access information or the information of the backhaul type, or send the access information or the information of the backhaul type to the fourth device. For specific details, please refer to Figure 5 the embodiments shown, which will not be elaborated here in detail. After the first device sends the access information or the information of the backhaul type to the fourth device, the fourth device may determine the user policy or the first Policy Control and Charging (PCC) rule according to the access information or the information of the backhaul type. For specific details, please refer to Figure 6 the embodiments shown, which will not be elaborated here in detail either. Thus, the QoS parameter information and the Packet Data Unit (PDU) session policy under the regenerative access mode can be obtained, so that the PDU session under the regenerative access mode can be better implemented.

[0125] In an embodiment of the present application, the first device may obtain the first configuration information or the access information of the regeneration access mode, and determine the backhaul type of the regeneration access mode according to the first configuration information and the access information. Thus, in an NTN communication system based on regeneration load, the first device may determine that the terminal accesses through the regeneration access mode and the backhaul type in the regeneration access mode, and may further obtain the backhaul link of the regeneration access mode according to the backhaul type. Optionally, since the first device may send the access information and the information of the backhaul type to the third device or the fourth device, the QoS parameter information and the Packet Data Unit (PDU) session policy in the regeneration access mode may be obtained, so that resource scheduling and PDU session in the regeneration access mode may be implemented.

[0126] As Figure 4 shown, an embodiment of the present application provides an information processing method 400, which may be executed by a second device. In other words, this information processing method may be executed by software or hardware installed in the second device. The information processing method includes the following steps.

[0127] S402: The second device sends access information to the first device, and the access information includes the access information of the regeneration access mode.

[0128] In a TNT communication system, when the terminal has accessed, the second device may obtain the access information and send the access information to the first device. The first device may be an AMF or an MME. The second device may be a RAN. The access information includes the access information of the regeneration access mode.

[0129] Optionally, in some embodiments, the access information may include the first information or the second information. The first information is used to indicate that the terminal accesses through the regeneration access mode. The second information is used to indicate whether there is participation of the ISL in the regeneration access mode or the participation information in the case of participation of the ISL.

[0130] The above regeneration access mode may include at least one of the following:

[0131] Access through the regeneration access mode via GEO, indicating that the base station type of the non-terrestrial base station is a high-orbit regeneration load type;

[0132] Access through the regeneration access mode via MEO, indicating that the base station type of the non-terrestrial base station is a medium-orbit regeneration load type;

[0133] Access through the regeneration access mode via LEO, indicating that the base station type of the non-terrestrial base station is a low-orbit regeneration load type;

[0134] Access through the regeneration access mode via other types of satellites, indicating that the base station type of the non-terrestrial base station is other types of regeneration load types.

[0135] It should be noted that in the NB-IoT communication system, the base station type of the non-terrestrial base station can also be the following types:

[0136] NB-IoT regenerative payload type;

[0137] NB-IoT store and forward (S&F) type;

[0138] NB-IoT high-orbit regenerative payload type;

[0139] NB-IoT medium-orbit regenerative payload type;

[0140] NB-IoT low-orbit regenerative payload type;

[0141] NB-IoT high-orbit store and forward type;

[0142] NB-IoT medium-orbit store and forward type;

[0143] NB-IoT low-orbit store and forward type.

[0144] It should also be noted that the regenerative access mode can also be referred to as the regenerative access type, or the regenerative payload type.

[0145] The above-mentioned participating information may include at least one of the following:

[0146] The hop count of the ISL;

[0147] The time delay of the ISL.

[0148] Optionally, in some embodiments, the second device may also perform the following operations:

[0149] The second device receives the first QoS parameter sent by the third device. The first QoS parameter can be determined by the third device according to the information of the backhaul type or the access information, or by the third device according to the first PCC rule.

[0150] The first QoS parameter may include a time delay, which may be the Core Network Packet delay budget (CN PDB). CN PDB refers to the packet transmission delay budget between the RAN and the anchor UPF, and may be a range value or an allowed offset factor. Optionally, CN PDB can be used for QoS flows or PDU sessions under the backhaul type of the regenerative access mode.

[0151] After receiving the first QoS parameter, the first device may, optionally, also perform the following operations:

[0152] The second device determines the second QoS parameter according to the first QoS parameter.

[0153] The second device performs resource scheduling according to the second QoS parameter.

[0154] The second QoS parameter may include a time delay, which may be an Access Network Packet delay budget (AN PDB).

[0155] When the second device determines the second QoS parameter according to the first QoS parameter, taking the first QoS parameter including CN PDB and the second QoS parameter including AN PDB as an example, if the CN PDB is a range, such as (20ms - 40ms), and the end-to-end delay is 100ms, then the second device may determine the AN PDB as (60ms - 80ms). If the CN PDB is 30ms and the CN PDB contains an allowable offset factor, such as 10ms, then the second device may determine the CN PDB as a range according to the offset factor of 10ms, that is, (20ms - 40ms). If the end-to-end delay is 100ms, then the second device may determine the AN PDB as (60ms - 80ms).

[0156] After determining the second QoS parameter, the second device may perform resource scheduling according to the second QoS parameter. Thus, resource scheduling in the regenerative access mode can be realized.

[0157] In the embodiments of the present application, since the second device may send the access information of the regenerative access mode to the first device, it is convenient for the first device to determine that the terminal accesses through the regenerative access mode. Optionally, since the second device may receive the first QoS parameter from the third device, determine the second QoS parameter according to the first QoS parameter, and perform resource scheduling according to the second QoS parameter, resource scheduling in the regenerative access mode can be realized.

[0158] As Figure 5 shown, the embodiments of the present application provide an information processing method 500. This information processing method may be executed by a third device. In other words, this information processing method may be executed by software or hardware installed in the third device. This information processing method includes the following steps.

[0161] The third device may be an SMF. The first device may be an AMF or an MME. The access information may be obtained by the first device and sent to the third device. For the specific implementation of how the first device obtains the access information, reference may be made to Figure 3 the embodiments shown, which will not be elaborated here in detail. The information on the backhaul type may indicate the backhaul type of the regenerative access mode. The backhaul type of the regenerative access mode may be determined by the first device according to the first configuration information or the access information. For the specific implementation, reference may be made to Figure 2 the embodiments shown, which will not be elaborated here either.

[0162] Optionally, in some embodiments, the access information may include the first information or the second information. The first information is used to indicate that the terminal accesses through the regenerative access mode, and the second information is used to indicate whether there is participation of the ISL in the regenerative access mode or the participation information in the case of the participation of the ISL.

[0176] NB-IOT Low-orbit Store-and-Forward Type.

[0177] It should also be noted that the regenerative access mode can also be referred to as the regenerative access type, or the regenerative load type.

[0178] The above participation information may include at least one of the following:

[0179] The hop count of the ISL;

[0190] Optionally, in some embodiments, when the third device sends the access information and the information of the backhaul type to the fourth device, the following operations may also be performed:

[0191] The third device receives the first PCC rule sent by the fourth device, and the first PCC rule is determined or generated by the fourth device according to the access information or the information of the backhaul type.

[0192] For the specific implementation manner in which the fourth device determines or generates the first PCC rule according to the access information or the information of the backhaul type, reference can be made to Figure 6 the embodiments shown, which will not be elaborated here. The first PCC rule can be applied to the PDU session under the backhaul type of the regenerative access mode. Optionally, the first PCC rule may include using the 5G Quality of Service Identifier (5G QoS Identifier, 5QI) or QoS parameters (such as PDB, priority), uplink maximum bitrate (UL-maximum bitrate), downlink maximum bitrate (DL-maximum bitrate), uplink guaranteed bitrate (UL-guaranteed bitrate), downlink guaranteed bitrate (DL-guaranteed bitrate), Address Resolution Protocol (ARP), Priority Level.

[0193] After receiving the first PCC rule, optionally, the third device may determine the first QoS parameter according to the first PCC rule. The first QoS parameter may include latency, and the latency may be CN PDB. CN PDB refers to the packet transmission latency budget between the RAN and the anchor UPF, and it can be a range value or an allowed offset factor. Optionally, CN PDB can be used for the QoS flow or PDU session under the backhaul type of the regenerative access mode.

[0194] After determining the first QoS parameter according to the first PCC rule, or after determining the first QoS parameter according to the access information or backhaul type information sent by the first device, optionally, the third device may send the first QoS parameter to the second device. When the third device sends the first QoS parameter to the second device, it may send it directly to the second device, or send the first QoS parameter to the first device, and then the first device forwards the first QoS parameter to the second device, which is not specifically limited here. The first device may be an MME or an AMF. The second device may be a RAN. After receiving the first QoS parameter, the second device may determine a second QoS parameter according to the first QoS parameter and perform resource scheduling according to the second QoS parameter, thereby realizing resource scheduling in the regenerative access mode. Among them, the specific implementation manner of the second device determining the second QoS parameter according to the first QoS parameter may refer to Figure 4 the embodiments shown, which will not be elaborated here.

[0195] In the embodiments of the present application, since the third device can receive the access information and backhaul type information of the regenerative access mode sent by the first device, and determine the first QoS parameter according to the access information and backhaul type information, or send the access information and backhaul type information of the regenerative access mode to the fourth device, and determine the first QoS parameter according to the first PCC rule generated by the fourth device, the QoS parameter information in the regenerative access mode can be obtained, thereby realizing resource scheduling in the regenerative access mode.

[0196] As Figure 6 shown, the embodiments of the present application provide an information processing method 600. This information processing method may be executed by a fourth device. In other words, this information processing method may be executed by software or hardware installed in the fourth device. The information processing method includes the following steps.

The backhaul type information may indicate the backhaul type of the regenerative access mode. The backhaul type of the regenerative access mode may be determined by the first device according to the first configuration information or access information.

[0204] Access through the regenerative access mode of other types of satellites, indicating that the base station type of the non-terrestrial base station is other types of regenerative load types.

[0205] It should be noted that in the NB-IOT communication system, the base station type of the non-terrestrial base station may also be the following types:

[0206] NB-IOT regenerative payload type;

[0207] NB-IOT store and forward (S&F) type;

[0214] It should also be noted that the regenerative access mode may also be referred to as the regenerative access type, or the regenerative load type.

[0215] The above participation information may include at least one of the following:

[0216] Hop count of ISL;

[0226] The dynamic backhaul type through the regenerative access mode of other types of satellites can be expressed as DYNAMIC other regenerative satellite backhaul, and the backhaul link changes dynamically, such as whether there is an ISL involved.

[0227] S604: The fourth device determines the user policy or the first PCC rule according to the access information or the information of the backhaul type.

[0228] Optionally, in some embodiments, when the fourth device receives the access information or the information of the backhaul type sent by the first device, the fourth device may determine the user policy according to the access information or the information of the backhaul type. When the fourth device receives the access information or the information of the backhaul type sent by the third device, the fourth device may determine the first PCC rule according to the access information or the information of the backhaul type.

[0229] The user policy may be applied to the PDU session under the backhaul type of the regeneration access mode. Taking the fourth device as the PCF as an example, the PCF may configure the slice applicable to the regeneration access mode, the data network name (DNN), or the session and service continuity mode (SSC mode) in the Route Selection Descriptor (RSD). Optionally, the user policy may be the UE Route Selection Policy (URSP).

[0230] After determining the user policy, optionally, the fourth device may send the user policy to the terminal. After receiving the user policy, the terminal may perform the PDU session based on the user policy, so as to implement the PDU session under the regeneration access mode.

[0231] The first PCC rule may be applied to the PDU session under the backhaul type of the regeneration access mode. Optionally, the first PCC rule may include 5QI or QoS parameters, UL-maximum bitrate, DL-maximum bitrate, UL-guaranteed bitrate, DL-guaranteed bitrate, ARP, PriorityLevel under the backhaul type of the regeneration access mode.

[0232] When the fourth device determines the first PCC policy according to the access information or the information of the backhaul type, optionally, when the access information includes the second information, and the second information includes the participation information of the ISL (the hop count or delay of the ISL), the fourth device may also calculate or determine the 5QI or QoS parameters (such as PDB, priority), UL-maximum bitrate, DL-maximum bitrate, UL-guaranteed bitrate, DL-guaranteed bitrate, ARP, Priority Level under the backhaul type of the regeneration access mode according to the hop count or delay of the ISL. For example, when the fourth device determines the PDB, the PDB may include the delay of the ISL link.

[0233] After the fourth device determines the first PCC rule, optionally, it may send the first PCC rule to the third device. After receiving the first PCC rule, the third device may determine the first QoS parameter according to the first PCC rule. For specific details, please refer to Figure 5 the embodiments shown below and will not be elaborated here.

[0234] In the embodiments of the present application, since the fourth device can receive the access information of the regenerative access mode and the information of the backhaul type sent by the first device or the third device, and determine the user policy or the first PCC rule according to the access information and the information of the backhaul type, the PDU session policy in the regenerative access mode can be obtained, so that the PDU session in the regenerative access mode can be better realized. Optionally, since the fourth device can send the first PCC rule to the third device, and the third device determines the first QoS parameter according to the first PCC rule, the QoS parameter information in the regenerative access mode can be obtained, so that the resource scheduling in the regenerative access mode can be realized.

[0235] To facilitate the understanding of the information processing method provided in the embodiments of the present application, the following will take Figures 7 to 11 a more specific implementation manner shown below as an example for description.

[0236] Figure 7 FIG. is a schematic flowchart of PDU session establishment in the regenerative access mode according to the embodiments of the present application, which may include the following steps.

[0237] Step 1: The UE sends a PDU session establishment request to the AMF.

[0238] Step 2: The AMF obtains the access information of the regenerative access mode.

[0239] The access information may include first information, and the first information is used to indicate that the UE accesses through the regenerative access mode, and the regenerative access mode includes at least one of the following:

[0240] Access through the regenerative access mode of the geostationary satellite (GEO), indicating that the base station type of the non-terrestrial base station is the high-orbit regenerative load type;

[0241] Access through the regenerative access mode of the medium Earth orbit satellite (MEO), indicating that the base station type of the non-terrestrial base station is the medium-orbit regenerative load type;

[0242] Access through the regenerative access mode of the low Earth orbit satellite (LEO), indicating that the base station type of the non-terrestrial base station is the low-orbit regenerative load type;

[0243] Access through the regenerative access mode of other types of satellites (othersat) indicates that the base station type of the non-terrestrial base station is other types of regenerative load types.

[0244] It should be noted that in the NB-IOT communication system, the base station type of the non-terrestrial base station can also be the following types:

[0245] NB-IOT regenerative payload type;

[0246] NB-IOT store and forward (S&F) type;

[0247] NB-IOT high-orbit regenerative payload type;

[0248] NB-IOT medium-orbit regenerative payload type;

[0249] NB-IOT low-orbit regenerative payload type;

[0250] NB-IOT high-orbit store and forward type;

[0251] NB-IOT medium-orbit store and forward type;

[0252] NB-IOT low-orbit store and forward type.

[0253] It should also be noted that the regenerative access mode can also be referred to as the regenerative access type, or the regenerative load type.

[0254] The access information can also include second information, which is used to indicate whether the UE participates in the ISL link in the regenerative access mode. In the case of participation in the ISL link, the second information also includes the number of hops or latency of the ISL.

[0255] In the case where the access information includes the first information, the AMF can obtain the first information from the RAN (see Figure 10 and Figure 11 ). In the case where the access information includes the second information, the AMF can obtain the second information from the RAN (see Figure 10 and Figure 11 ), or determine the second information according to the second configuration information.

[0256] The second configuration information is the local configuration information of the AMF. When the AMF determines the second information according to the second configuration information, in one possible implementation, it may include: when the AMF receives a Non-Access Stratum (NAS) message from the UE or an N2 message from the RAN, the AMF obtains the second information based on the local configuration information, and the local configuration information includes the mapping relationship between the TAI and the second information. For example, if the ISL mapped by TAI#1 is two hops, or the time delay is 6 ms, then the second information may be that the ISL hop count is two hops or the time delay is 6 ms.

[0257] Step 3: The AMF determines the backhaul type of the regenerative access mode.

[0258] When the AMF determines the backhaul type of the regenerative access mode, in one implementation, it may be determined according to the first configuration information. The first configuration information is the local configuration information of the AMF, and may include at least one of the following:

[0259] The mapping relationship between the RAN ID and the backhaul type;

[0260] The mapping relationship between the TAI and the backhaul type.

[0261] When the AMF determines the backhaul type according to the above mapping relationship, for example, if RAN ID#1 maps to the LEO regenerative satellite backhaul type, then the AMF may determine that the backhaul type of the current UE is the LEO regenerative satellite backhaul type. Another example is that if TAI#1 maps to the LEO regenerative satellite backhaul type, then the AMF may determine that the backhaul type of the current UE is the LEO regenerative satellite backhaul type.

[0262] In another implementation, the AMF may determine the backhaul type of the regenerative access mode according to the access information. Specifically, it may include at least one of the following:

[0263] If the access information includes the first information and the first information is accessed through the regenerative access mode of a geostationary orbit (GEO) satellite, the backhaul type is GEO regenerative satellite backhaul. If the access information further includes the second information, the backhaul type is DYNAMIC GEO regenerative satellite backhaul;

[0264] If the access information includes the first information and the first information is accessed through the regenerative access mode of the Medium Earth Orbit (MEO) satellite, the backhaul type is MEO regenerative satellite backhaul. If the access information further includes the second information, the backhaul type is DYNAMIC MEO regenerative satellite backhaul;

[0265] If the access information includes the first information and the first information is accessed through the regenerative access mode of the Low Earth Orbit (LEO) satellite, the backhaul type is LEO regenerative satellite backhaul. If the access information further includes the second information, the backhaul type is DYNAMIC LEO regenerative satellite backhaul;

[0266] If the access information includes the first information and the first information is accessed through the regenerative access mode of other types of satellites (othersat), the backhaul type is othersat regenerative satellite backhaul. If the access information further includes the second information, the backhaul type is DYNAMIC othersat regenerative satellite backhaul.

[0267] Step 4: The AMF sends the access information of the regenerative access mode or the information of the backhaul type to the SMF.

[0268] Optionally, if the information of the backhaul type does not include the dynamic backhaul type, the access information sent by the AMF to the SMF can be the first information sent to the SMF. If the information of the backhaul type includes the dynamic backhaul type, the access information sent by the AMF to the SMF can be the second information sent to the SMF, or the first information and the second information.

[0269] Step 5: The SMF sends a response message to the AMF.

[0270] Step 6: The network performs the authentication and authorization process for the PDU session of the UE.

[0271] Step 7: The SMF sends the access information of the regenerative access mode or the information of the backhaul type to the PCF.

[0272] For example, the SMF can send an NPcf_SMPolicyControl_Create message to the PCF, and the access information or the information of the backhaul type is carried in this message.

[0273] Optionally, the information sent by the SMF to the PCF may be the same as the information sent by the AMF to the SMF in step 4.

[0274] Step 8: The PCF and the SMF perform a session management policy (SM policy) establishment process.

[0275] Step 9: The PCF generates a first PCC rule based on the access information of the regeneration access mode or the information of the backhaul type.

[0276] The first PCC rule can be applied to the PDU session under the backhaul type of the regeneration access mode. Optionally, if the access information received by the PCF includes the second information, the PCF also considers the second information when generating the first PCC rule. The first PCC rule may include the following principles:

[0277] The first PCC rule contains the following principles:

[0278] a) Use 5QI or QoS parameters (packet delay budget PDB, priority), UL-maximum bitrate, DL-maximum bitrate, UL-guaranteed bitrate, DL-guaranteed bitrate, ARP, Priority Level under the backhaul type of the regeneration access mode;

[0279] b) If the second information is considered, the PCF may also calculate or determine 5QI or QoS parameters (packet delay budget PDB, priority), UL-maximum bitrate, DL-maximum bitrate, UL-guaranteed bitrate, DL-guaranteed bitrate, ARP, Priority Level under the backhaul type of the regeneration access mode according to the ISL hop count or delay information in the second information. For example, when determining the PDB, the PDB may include the delay of the ISL link.

[0280] Step 10: The PCF sends the first PCC rule to the SMF.

[0281] Step 11: The SMF performs N4 session establishment.

[0282] Step 12: The SMF determines the first QoS parameter.

[0283] If steps 7-10 are executed, the SMF may determine the first QoS parameter according to the first PCC rule. If steps 7-10 are not executed, the SMF may determine the first QoS parameter according to the access information or backhaul type sent by the AMF and the locally configured policy information.

[0284] The first QoS parameter may include CN PDB. CN PDB refers to the packet transmission delay budget between the RAN and the anchor UPF, and can be used for QoS flows or PDU sessions in the backhaul type of the regenerative access mode.

[0285] Step 13: The SMF sends the first QoS parameter to the AMF.

[0286] For example, the SMF may send a Namf_Communication_N1N2MessageTransfer message to the AMF, and the first QoS parameter is carried in this message.

[0287] Step 14: The AMF forwards the first QoS parameter to the RAN.

[0288] Step 15: The AMF sends a PDU session establishment acceptance response of the SMF to the UE.

[0289] Figure 8 It is a schematic flowchart of generating a user policy by the PCF according to an embodiment of the present application. In the UE policy association phase, the AMF may send the backhaul type of the regenerative access mode to the PCF, and the PCF generates a user policy for the regenerative access mode, which may include the following steps.

[0290] Step 1: The AMF sends the access information or backhaul type of the regenerative access mode to the PCF.

[0291] For example, the AMF may send an Npcf_UEPolicyControl_Create Request to the PCF, carrying the access information or the backhaul type of the regenerative access mode.

[0292] Step 2: The PCF sends a response message to the AMF.

[0293] For example, the PCF may send an Npcf_UEPolicyControl_Create Responser to the AMF.

[0294] Step 3: The PCF generates a user policy according to the access information or backhaul type of the regenerative access mode.

[0295] The user policy may include URSP. The user policy can be applied to PDU sessions in the backhaul type of the regenerative access mode. For example, the PCF configures slices, DNNs, or SSC modes applicable to the regenerative access mode in the RSD.

[0296] Figure 9It is a schematic flowchart of the RAN applying the CN PDB according to an embodiment of the present application. During the PDU session establishment or modification process, the following steps may be included.

[0297] Step 1: The SMF sends the CN PDB to the RAN.

[0298] Step 2: The RAN determines the AN PDB according to the CN PDB.

[0299] Optionally, if the backhaul type of the regenerative access mode includes a dynamic backhaul type, the CN PDB may include any of the following forms:

[0300] a) The CN PDB is a range, such as (20ms - 40ms). The RAN determines the AN PDB according to this range. For example, if the end-to-end delay is 100ms, then the RAN determines that the AN PDB is (60ms - 80ms);

[0301] b) The CN PDB may include an allowable offset factor, such as 10ms. If the CN PDB is 30ms, then according to the offset factor of 10ms, the RAN can determine that the CN PDB is (20ms - 40ms). For an end-to-end delay of 100ms, then the RAN determines that the AN PDB is (60ms - 80ms).

[0302] Step 3: The RAN performs resource scheduling according to the AN PDB.

[0303] Figure 10 It is a schematic flowchart of the RAN sending access information according to an embodiment of the present application, which may include the following steps.

[0304] Step 1: The UE sends a registration request to the RAN.

[0305] Step 2: The RAN sends the registration request and the access information of the regenerative access mode to the AMF.

[0306] The access information includes the first information or the second information. If the UE accesses through the regenerative access mode, then the RAN may send the first information to the AMF. If the ISL link is involved, then the RAN may also send the second information to the AMF. The first information is used to indicate that the UE accesses through the regenerative access mode, and the second information is used to indicate the participation information of the ISL, such as the number of hops or delay of the ISL. Among them, the regenerative access mode may include at least one of the following:

[0307] Access through the regenerative access mode of a geostationary orbit satellite (GEO), indicating that the UE accesses through a base station deployed on a geostationary orbit satellite;

[0308] Access through the regenerative access mode of Medium Earth Orbit (MEO) satellites means that the UE accesses through the base stations deployed on MEO satellites;

[0309] Access through the regenerative access mode of Low Earth Orbit (LEO) satellites means that the UE accesses through the base stations deployed on LEO satellites;

[0310] Access through the regenerative access mode of other types of satellites (othersat) means that the UE accesses through the base stations deployed on other types of satellites.

[0311] Step 3: The AMF determines the regenerative access mode of the UE based on the access information.

[0312] Step 4: The AMF performs processes such as authentication, encryption, and policy establishment.

[0313] Step 5: The AMF sends a registration acceptance message to the UE.

[0314] Figure 11 It is a schematic flowchart of the RAN sending access information according to an embodiment of the present application, which may include the following steps.

[0315] Step 1: The UE sends a service request to the RAN.

[0316] Step 2: The RAN sends the service request and access information of the regenerative access mode to the AMF.

[0317] The access information includes the first information or the second information. If the UE accesses through the regenerative access mode, then the RAN can send the first information to the AMF. If the Inter-Satellite Link (ISL) is involved, then the RAN can also send the second information to the AMF. The first information is used to indicate that the UE accesses through the regenerative access mode, and the second information is used to indicate the participation information of the ISL, such as the number of hops or latency of the ISL. Among them, the regenerative access mode may include at least one of the following:

[0318] Access through the regenerative access mode of Geostationary Earth Orbit (GEO) satellites means that the UE accesses through the base stations deployed on GEO satellites;

[0319] Access through the regenerative access mode of Medium Earth Orbit (MEO) satellites means that the UE accesses through the base stations deployed on MEO satellites;

[0320] Access through the regenerative access mode of Low Earth Orbit (LEO) satellites means that the UE accesses through the base stations deployed on LEO satellites;

[0321] Access through the regenerative access mode of other types of satellites (othersat) means that the UE accesses through the base station deployed on other types of satellites.

[0322] Step 3: The AMF determines the regenerative access mode of the UE according to the access information.

[0323] Step 4: The AMF performs session or user plane activation.

[0324] Step 5: The AMF sends a service acceptance message to the UE.
