[0004] A non-terrestrial network (NTN) communication system refers to a system that implements New Radio (NR) communication through mobile platforms such as satellites or drones.

Under different NTN communication systems, the access methods of terminals are different, and the backhaul links under different access methods are also different.

[0063] Figure 2 shows a block diagram of an NTN communication system that can be applied in an embodiment of the present application. The NTN communication system includes a terminal 11, a satellite (or a mobile platform such as a drone) 22, and a ground gateway 23. The link between the terminal 11 and the satellite 22 is called a service link (i.e., a service link), and the link between the satellite 22 and the ground gateway 23 is called a feeder link (i.e., a feeder link). In certain scenarios (such as low-orbit satellites (LEO), due to satellite movement, a service link or feeder link switching may occur. For service link switching, the service satellite of all terminals in the cell needs to be switched from one satellite to another. For feeder link switching, a satellite needs to be switched from one ground gateway to another. NTN communication systems include two types: an NTN communication system based on a transparent payload and an NTN communication system based on a regenerative payload. The technical solution provided in the embodiment of the present application can be applied to an NTN communication system based on a regenerative payload. In this system, terminals, base stations and core network equipment are all deployed on the ground. The communication data between terminals and network equipment is transferred via satellites in the air. The satellites have some or all of the base station functions and can decode and process uplink or downlink data.

[0064] It should be noted that the scenarios corresponding to the various embodiments of the present application may be scenarios where network side devices, or some hardware or functions in the network side devices, can be moved. For example, the network side devices, or some hardware or functions in the network side devices, are located on satellites, or are located on other movable devices (such as cars, airplanes, drones, ships, and other mobile vehicles). The following will take the network side devices, or some hardware or functions in the network side devices, located on satellites as an example, but it can be understood that movable devices are not limited to satellites, but can also be other types of devices mentioned above.

[0065] The information processing method and network-side device provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0066] As shown in Figure 3, an embodiment of the present application provides an information processing method 300, which can be executed by a first device. In other words, the information processing method can be executed by software or hardware installed on the first device. The information processing method includes the following steps.

[0067] S302: The first device obtains first configuration information or access information, where the access information includes access information of a regeneration access mode.

[0068] In the NTN communication system, when the terminal has been connected, the first device can obtain the first configuration information and the access information. The first device can be an AMF or an MME.

[0069] The first configuration information may be local configuration information of the first device. When the first device obtains the first configuration information, it may obtain the first configuration information locally. Optionally, in some embodiments, the first configuration information may be used to indicate (or may include) at least one of the following:

[0070] a second mapping relationship between a Radio Access Network ID (RAN ID) and a backhaul type, the backhaul type including a backhaul type of a regenerative access mode;

[0071] A third mapping relationship between a Tracking Area ID (TAI) and a backhaul type, where the backhaul type includes a backhaul type of a regeneration access mode.

[0072] The access information may include access information of a regenerative access mode. Optionally, in some embodiments, the access information may include first information or second information. The first information is used to indicate that the terminal accesses via the regenerative access mode, and the second information is used to indicate whether an inter-satellite link (ISL) is involved in the regenerative access mode, or participation information if an ISL is involved.

[0073] The above regeneration access mode may include at least one of the following:

[0074] Access through regenerative access via Geostationary Earth Orbit (GEO) satellites;

[0075] Access via regenerative access via medium earth orbit (MEO) satellites;

[0076] Access via regenerative access via Low Earth Orbit (LEO) satellites;

[0077] Access through regenerative access of other types of satellites (othersat).

[0078] Among them, access via GEO regenerative access mode can indicate that the base station type of the non-ground base station is a high orbit regenerative load type. Access via MEO regenerative access mode can indicate that the base station type of the non-ground base station is a medium orbit regenerative load type. Access via LEO regenerative access mode can indicate that the base station type of the non-ground base station is a low orbit regenerative load type. Access via other types of satellite regenerative access mode can indicate that the base station type of the non-ground base station is other types of regenerative load types.

[0079] It should be noted that in the Narrow Band Internet of Things (NB-IoT) communication system, the base station type of non-ground base station can also be the following types:

[0080] NB-IOT regenerative payload type;

[0081] NB-IOT store and forward (S&F) type;

[0082] NB-IOT high track regenerative load type;

[0083] Types of track regenerative loads in NB-IOT;

[0084] NB-IOT low-orbit regenerative load type;

[0085] NB-IOT high-orbit store and forward type;

[0086] Track store and forward type in NB-IOT;

[0087] NB-IOT low-orbit store and forward type.

[0088] It should also be noted that the regeneration access mode may also be referred to as a regeneration access type or a regeneration load type.

[0089] The above-mentioned participation information may include at least one of the following:

[0090] The number of hops of the ISL;

[0091] ISL latency.

[0092] When the first device obtains the access information, it may obtain the access information according to the local configuration information or obtain the access from other devices. Optionally, in some embodiments, when the access information includes the first information, the first device obtaining the access information may include:

[0093] The first device receives access information sent by the second device.

[0094] The second device may be a RAN.

[0095] Optionally, in some implementations, when the access information includes the second information, the first device acquiring the access information may include at least one of the following:

[0096] The first device receives access information sent by the second device;

[0097] The first device determines access information according to the second configuration information.

[0098] The second configuration information may be 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 based on the second configuration information, it may determine the access information based on the first mapping relationship. For example, if there is a first mapping relationship between TAI#1 and an ISL of two hops or a latency of 6ms, then when determining the access information, the first device may determine, based on TAI#1, that the second information in the access information is an ISL hop count of two hops or a latency of 6ms.

[0099] Optionally, in some embodiments, the first device (AMF) receives access information of the regeneration access mode of the second device (RAN), and may also determine mobility restrictions information (mobility restrictions) based on the access information of the regeneration access mode, i.e., radio technology restriction information (RAT) of the terminal in the regeneration access mode, forbidden area, service area restriction, core network type restriction, etc. Among them:

[0100] Forbidden Area: Terminals are prohibited from accessing this area and cannot send any messages to network-side devices.

[0101] RAT Restriction: defines the RAT types that the terminal cannot access.

[0102] Service Area Restriction: It is divided into Allowed Area and Non-Allowed Area. In the Allowed Area, the terminal can access the network side equipment normally. In the Non-Allowed Area, it can initiate periodic update and registration requests, but cannot initiate SR and any session-related signaling.

[0103] Optionally, the first device may further send radio technology restriction information (RAT), forbidden area, service area restriction, and core network type restriction under the determined regeneration access mode to the second device (RAN) or terminal.

[0104] S304: The first device determines a backhaul type according to the first configuration information or the access information, where the backhaul type includes a backhaul type of a regeneration access mode.

[0105] After acquiring the first configuration information and the access information, the first device may determine a backhaul type according to the first configuration information or the access information, where the backhaul type includes a regenerative satellite backhaul type.

[0106] As described in S302, the first configuration information may include at least one of a second mapping relationship between a RAN ID and a backhaul type and a third mapping relationship between a TAI and a backhaul type. Then, when the first device determines the backhaul type based on the first configuration information, it may optionally include at least one of the following:

[0107] The first device determines the return type according to the second mapping relationship;

[0108] The first device determines the return type according to the third mapping relationship.

[0109] 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.

[0110] 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.

[0111] As described in S302, the access information may include first information or second information, the first information being used to indicate that the terminal accesses via a regenerative access mode, and the second information being used to indicate whether an ISL is involved in the regenerative access mode or the participation information if an ISL is involved. Therefore, when the first device determines the backhaul type based on the access information, if the access information includes the first information, it may optionally include at least one of the following:

[0112] When the first information indicates that the terminal accesses through a regenerative access mode of GEO, determining the backhaul type to be a backhaul type through a regenerative access mode of GEO;

[0113] In a case where the first information indicates that the terminal accesses through the regenerative access mode of MEO, determining the backhaul type to be a backhaul type through the regenerative access mode of MEO;

[0114] In a case where the first information indicates that the terminal accesses through a regenerative access mode of LEO, determining the backhaul type to be a backhaul type through a regenerative access mode of LEO;

[0115] In a case where the first information indicates that the terminal accesses the satellite through a regenerative access method of another type, the backhaul type is determined to be a backhaul type through a regenerative access method of another type of satellite.

[0116] The backhaul type through the regenerative access method of GEO can be expressed as GEO regenerative satellite backhaul, the backhaul type through the regenerative access method of MEO can be expressed as MEO regenerative satellite backhaul, the backhaul type through the regenerative access method of LEO can be expressed as LEO regenerative satellite backhaul, and the backhaul type through the regenerative access method of other types of satellites can be expressed as other regenerative satellite backhaul.

[0117] In a case where 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, at least one of the following may be included:

[0118] When the first information indicates that the terminal accesses through a regenerative access mode of GEO, determining the backhaul type to be a dynamic backhaul type through a regenerative access mode of GEO;

[0119] In a case where the first information indicates that the terminal accesses through the regenerative access mode of MEO, determining the backhaul type to be a dynamic backhaul type through the regenerative access mode of MEO;

[0120] In a case where the first information indicates that the terminal accesses through a regenerative access mode of LEO, determining the backhaul type to be a dynamic backhaul type through a regenerative access mode of LEO;

[0121] In a case where the first information indicates that the terminal accesses the satellite through a regenerative access mode of another type, the backhaul type is determined to be a dynamic backhaul type through a regenerative access mode of another type of satellite.

[0122] The dynamic backhaul type for regenerative access via GEO can be expressed as DYNAMIC GEO regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved. The dynamic backhaul type for regenerative access via MEO can be expressed as DYNAMIC MEO regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved. The dynamic backhaul type for regenerative access via LEO can be expressed as DYNAMIC LEO regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved. The dynamic backhaul type for regenerative access via other types of satellites can be expressed as DYNAMIC other regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved.

[0123] Optionally, in some implementations, after determining the backhaul type of the regeneration access mode, the first device may perform at least one of the following operations:

[0124] The first device sends access information or return type information to the third device;

[0125] The first device sends access information or return type information to the fourth device.

[0126] The third device may be an SMF. The fourth device may be a PCF. The backhaul type information may indicate the backhaul type of the regeneration access mode. After the first device sends access information or backhaul type information to the third device, the third device may determine a first quality of service (QoS) parameter based on the access information or backhaul type information, or send the access information or backhaul type information to the fourth device. For details, please refer to the embodiment shown in FIG5 , which will not be described in detail here. After the first device sends access information or backhaul type information to the fourth device, the fourth device may determine a user policy or a first policy control and charging (PCC) rule based on the access information or backhaul type information. For details, please refer to the embodiment shown in FIG6 , which will not be described in detail here. In this way, the QoS parameter information and the packet data unit (PDU) session policy under the regeneration access mode can be obtained, so that the PDU session under the regeneration access mode can be better implemented.

[0127] In an embodiment of the present application, a first device can obtain first configuration information or access information of a regenerative access mode, and determine the backhaul type of the regenerative access mode based on the first configuration information and the access information. Thus, in a regenerative load-based NTN communication system, the first device can determine whether a terminal accesses via the regenerative access mode and the backhaul type under the regenerative access mode, and further obtain the backhaul link of the regenerative access mode based on the backhaul type. Optionally, because the first device can send the access information and backhaul type information to a third device or a fourth device, QoS parameter information and a packet data unit (PDU) session policy under the regenerative access mode can be obtained, thereby enabling resource scheduling and PDU session under the regenerative access mode.

[0128] As shown in FIG4 , an embodiment of the present application provides an information processing method 400 , which can be executed by a second device. In other words, the information processing method can be executed by software or hardware installed on the second device. The information processing method includes the following steps.

[0129] S402: The second device sends access information to the first device, where the access information includes access information of the regeneration access mode.

[0130] In a TNT communication system, if a terminal has already accessed, a second device can obtain access information and send it to a first device. The first device can be an AMF or MME. The second device can be a RAN. The access information includes access information for the regeneration access mode.

[0131] Optionally, in some implementations, the access information may include first information or second information, wherein the first information is used to indicate that the terminal accesses via a regenerative access mode, and the second information is used to indicate whether an ISL is involved in the regenerative access mode or participation information if an ISL is involved.

[0132] The above regeneration access mode may include at least one of the following:

[0133] Accessed through GEO regenerative access mode, indicating that the base station type of the non-ground base station is a high-orbit regenerative load type;

[0134] Accessed through MEO regenerative access mode, indicating that the base station type of the non-ground base station is the medium orbit regenerative load type;

[0135] Accessed through LEO regenerative access mode, indicating that the base station type of the non-ground base station is a low-orbit regenerative load type;

[0136] Accessed through regenerative access mode of other types of satellites, indicating that the base station type of the non-ground base station is other types of regenerative load types.

[0137] It should be noted that in the NB-IOT communication system, the base station type of non-ground base station can also be the following types:

[0138] NB-IOT regenerative payload type;

[0139] NB-IOT store and forward (S&F) type;

[0140] NB-IOT high track regenerative load type;

[0141] Types of track regenerative loads in NB-IOT;

[0142] NB-IOT low-orbit regenerative load type;

[0143] NB-IOT high-orbit store and forward type;

[0144] Track store and forward type in NB-IOT;

[0145] NB-IOT low-orbit store and forward type.

[0146] It should also be noted that the regeneration access mode may also be referred to as a regeneration access type or a regeneration load type.

[0147] The above-mentioned participation information may include at least one of the following:

[0148] The number of hops of the ISL;

[0149] ISL latency.

[0150] Optionally, in some implementations, the second device may further perform the following operations:

[0151] 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 backhaul type information or access information, or determined by the third device according to the first PCC rule.

[0152] The first QoS parameter may include latency, which may be the Core Network Packet Delay Budget (CN PDB). The CN PDB refers to the packet transmission delay budget between the RAN and the anchor UPF, which may be a range value or an allowed offset factor. Optionally, the CN PDB may be used for QoS flows or PDU sessions in a backhaul type of regeneration access mode.

[0153] After receiving the first QoS parameter, the first device may optionally further perform the following operations:

[0154] The second device determines a second QoS parameter according to the first QoS parameter.

[0155] The second device performs resource scheduling according to the second QoS parameter.

[0156] The second QoS parameter may include delay, which may be an access network packet delay budget (AN PDB).

[0157] When the second device determines the second QoS parameter based on the first QoS parameter, taking the example that the first QoS parameter includes CN PDB and the second QoS parameter includes AN PDB, if CN PDB is a range, such as (20ms-40ms), and the end-to-end delay is 100ms, then the second device can determine that AN PDB is (60ms-80ms); if CN PDB is 30ms and CN PDB contains an allowed offset factor, such as 10ms, then the second device can determine that CN PDB is a range based on the offset factor 10ms, that is, (20ms-40ms); if the end-to-end delay is 100ms, then the second device can determine that AN PDB is (60ms-80ms).

[0158] After determining the second QoS parameter, the second device can perform resource scheduling according to the second QoS parameter, thereby achieving resource scheduling in a regenerative access mode.

[0159] In the embodiment of the present application, since the second device can send access information of the regeneration access mode to the first device, it is convenient for the first device to determine that the terminal is accessing via the regeneration access mode. Optionally, since the second device can receive the first QoS parameter from the third device, determine the second QoS parameter based on the first QoS parameter, and perform resource scheduling based on the second QoS parameter, resource scheduling under the regeneration access mode can be implemented.

[0160] As shown in Figure 5, an embodiment of the present application provides an information processing method 500, which can be executed by a third device. In other words, the information processing method can be executed by software or hardware installed on the third device. The information processing method includes the following steps.

[0161] S502: The third device receives access information or backhaul type information sent by the first device, where the access information includes access information of the regeneration access mode, and the backhaul type includes a backhaul type of the regeneration access mode.

[0162] S504: The third device performs at least one of the following according to the access information or the backhaul type information: sending the access information or the backhaul type information to the fourth device; and determining a first QoS parameter.

[0163] The third device may be an SMF. The first device may be an AMF or MME. The access information may be obtained by the first device and sent to the third device. The specific implementation of how the first device obtains the access information can be found in the embodiment shown in Figure 3 and will not be described in detail here. The backhaul type information may indicate the backhaul type of the regeneration access mode. The backhaul type of the regeneration access mode may be determined by the first device based on the first configuration information or the access information. The specific implementation can be found in the embodiment shown in Figure 2 and will not be described in detail here.

[0164] Optionally, in some implementations, the access information may include first information or second information. The first information is used to indicate that the terminal accesses via a regenerative access mode, and the second information is used to indicate whether an ISL is involved in the regenerative access mode or participation information if an ISL is involved.

[0165] The above regeneration access mode may include at least one of the following:

[0166] Accessed through GEO regenerative access mode, indicating that the base station type of the non-ground base station is a high-orbit regenerative load type;

[0167] Accessed through MEO regenerative access mode, indicating that the base station type of the non-ground base station is the medium orbit regenerative load type;

[0168] Accessed through LEO regenerative access mode, indicating that the base station type of the non-ground base station is a low-orbit regenerative load type;

[0169] Accessed through regenerative access mode of other types of satellites, indicating that the base station type of the non-ground base station is other types of regenerative load types.

[0170] It should be noted that in the NB-IOT communication system, the base station type of non-ground base station can also be the following types:

[0171] NB-IOT regenerative payload type;

[0172] NB-IOT store and forward (S&F) type;

[0173] NB-IOT high track regenerative load type;

[0174] Types of track regenerative loads in NB-IOT;

[0175] NB-IOT low-orbit regenerative load type;

[0176] NB-IOT high-orbit store and forward type;

[0177] Track store and forward type in NB-IOT;

[0178] NB-IOT low-orbit store and forward type.

[0179] It should also be noted that the regeneration access mode may also be referred to as a regeneration access type or a regeneration load type.

[0180] The above-mentioned participation information may include at least one of the following:

[0181] The number of hops of the ISL;

[0182] ISL latency.

[0183] The above return types include at least one of the following:

[0184] The backhaul type through GEO regenerative access can be expressed as GEO regenerative satellite backhaul;

[0185] The backhaul type through the regenerative access method of MEO can be expressed as MEO regenerative satellite backhaul;

[0186] The backhaul type through the regenerative access method of LEO can be expressed as LEO regenerative satellite backhaul;

[0187] The backhaul type through regenerative access of other types of satellites can be expressed as other regenerative satellite backhaul;

[0188] The dynamic backhaul type through GEO regenerative access can be expressed as DYNAMIC GEO regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved;

[0189] The dynamic backhaul type through MEO regenerative access can be expressed as DYNAMIC MEO regenerative satellite backhaul, where the backhaul link changes dynamically, such as whether ISL is involved;

[0190] The dynamic backhaul type through LEO regenerative access can be expressed as DYNAMIC LEO regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved;

[0191] The dynamic backhaul type through regenerative access of other types of satellites can be expressed as DYNAMIC other regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved.

[0192] Optionally, in some implementations, when the third device sends the access information and the backhaul type information to the fourth device, it may further perform the following operations:

[0193] The third device receives the first PCC rule sent by the fourth device, where the first PCC rule is determined or generated by the fourth device according to the access information or the backhaul type information.

[0194] The specific implementation method in which the fourth device determines or generates the first PCC rule based on the access information or the backhaul type information can be found in the embodiment shown in FIG6 and will not be described in detail here. The first PCC rule can be applied to a PDU session under the backhaul type of the regeneration access method. Optionally, the first PCC rule may include a 5G quality of service identifier (5G QoS Identifier, 5QI) or QoS parameters (such as PDB, priority) under the backhaul type using the regeneration access method, uplink maximum bit rate (UL-maximum bitrate), downlink maximum bit rate (DL-maximum bitrate), uplink guaranteed bit rate (UL-guaranteed bitrate), downlink guaranteed bit rate (DL-guaranteed bitrate), Address Resolution Protocol (ARP), and priority level.

[0195] After receiving the first PCC rule, the third device may optionally determine a first QoS parameter based on the first PCC rule. The first QoS parameter may include latency, which may be a CN PDB. The CN PDB refers to the packet transmission delay budget between the RAN and the anchor UPF, which may be a range value or an allowed offset factor. Optionally, the CN PDB can be used to regenerate a QoS flow or PDU session in a backhaul-type access mode.

[0196] After the third device determines the first QoS parameter according to the first PCC rule, or determines the first QoS parameter according to the access information or backhaul type information sent by the first device, it can optionally send the first QoS parameter to the second device. When the third device sends the first QoS parameter to the second device, it can 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. There is no specific limitation here. The first device can be an MME or an AMF. The second device can be a RAN. After receiving the first QoS parameter, the second device can determine the second QoS parameter based on the first QoS parameter, and perform resource scheduling based on the second QoS parameter, thereby realizing resource scheduling under the regeneration access mode. Among them, the specific implementation method of the second device determining the second QoS parameter based on the first QoS parameter can be referred to the embodiment shown in Figure 4, which will not be described in detail here.

[0197] In an embodiment of the present application, since the third device can receive the access information and backhaul type information of the regeneration access mode sent by the first device, and determine the first QoS parameter based on the access information and backhaul type information, or send the access information and backhaul type information of the regeneration access mode to the fourth device, and determine the first QoS parameter based on the first PCC rule generated by the fourth device, the QoS parameter information under the regeneration access mode can be obtained, thereby realizing resource scheduling under the regeneration access mode.

[0198] As shown in Figure 6, an embodiment of the present application provides an information processing method 600, which can be executed by a fourth device. In other words, the information processing method can be executed by software or hardware installed on the fourth device. The information processing method includes the following steps.

[0199] S602: The fourth device receives access information or backhaul type information sent by the first device or the third device, where the access information includes access information of the regeneration access mode, and the backhaul type includes a backhaul type of the regeneration access mode.

[0200] The first device may be an AMF or MME. The third device may be an SMF. The fourth device may be a PCF. The access information may be acquired by the first device and sent to the fourth device, or acquired by the first device and sent to the third device, which then is sent to the fourth device. The specific implementation of how the first device acquires the access information can be found in the embodiment shown in Figure 3 and will not be described in detail here. The backhaul type information may indicate the backhaul type of the regeneration access method. The backhaul type of the regeneration access method may be determined by the first device based on the first configuration information or the access information. The specific implementation can be found in the embodiment shown in Figure 2 and will not be described in detail here.

[0201] Optionally, in some implementations, the access information may include first information or second information. The first information is used to indicate that the terminal accesses via a regenerative access mode, and the second information is used to indicate whether an ISL is involved in the regenerative access mode or participation information if an ISL is involved.

[0202] The above regeneration access mode may include at least one of the following:

[0203] Accessed through GEO regenerative access mode, indicating that the base station type of the non-ground base station is a high-orbit regenerative load type;

[0204] Accessed through MEO regenerative access mode, indicating that the base station type of the non-ground base station is the medium orbit regenerative load type;

[0205] Accessed through LEO regenerative access mode, indicating that the base station type of the non-ground base station is a low-orbit regenerative load type;

[0206] Accessed through regenerative access mode of other types of satellites, indicating that the base station type of the non-ground base station is other types of regenerative load types.

[0207] It should be noted that in the NB-IOT communication system, the base station type of non-ground base station can also be the following types:

[0208] NB-IOT regenerative payload type;

[0209] NB-IOT store and forward (S&F) type;

[0210] NB-IOT high track regenerative load type;

[0211] Types of track regenerative loads in NB-IOT;

[0212] NB-IOT low-orbit regenerative load type;

[0213] NB-IOT high-orbit store and forward type;

[0214] Track store and forward type in NB-IOT;

[0215] NB-IOT low-orbit store and forward type.

[0216] It should also be noted that the regeneration access mode may also be referred to as a regeneration access type or a regeneration load type.

[0217] The above-mentioned participation information may include at least one of the following:

[0218] The number of hops of the ISL;

[0219] ISL latency.

[0220] The above return types include at least one of the following:

[0221] The backhaul type through GEO regenerative access can be expressed as GEO regenerative satellite backhaul;

[0222] The backhaul type through the regenerative access method of MEO can be expressed as MEO regenerative satellite backhaul;

[0223] The backhaul type through the regenerative access method of LEO can be expressed as LEO regenerative satellite backhaul;

[0224] The backhaul type through regenerative access of other types of satellites can be expressed as other regenerative satellite backhaul;

[0225] The dynamic backhaul type through GEO regenerative access can be expressed as DYNAMIC GEO regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved;

[0226] The dynamic backhaul type through MEO regenerative access can be expressed as DYNAMIC MEO regenerative satellite backhaul, where the backhaul link changes dynamically, such as whether ISL is involved;

[0227] The dynamic backhaul type through LEO regenerative access can be expressed as DYNAMIC LEO regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved;

[0228] The dynamic backhaul type through regenerative access of other types of satellites can be expressed as DYNAMIC other regenerative satellite backhaul. The backhaul link changes dynamically, such as whether ISL is involved.

[0229] S604: The fourth device determines a user policy or a first PCC rule according to the access information or the backhaul type information.

[0230] Optionally, in some embodiments, when the fourth device receives access information or return type information sent by the first device, the fourth device may determine the user policy based on the access information or return type information; when the fourth device receives access information or return type information sent by the third device, the fourth device may determine the first PCC rule based on the access information or return type information.

[0231] The user policy can be applied to a PDU session under the backhaul type of the regeneration access mode. Taking the fourth device as a PCF as an example, the PCF can configure the slice, data network name (DNN) or session and service continuity mode (SSC mode) applicable to the regeneration access mode in the route selection descriptor (RSD). Optionally, the user policy can be a user route selection policy (URSP).

[0232] After determining the user policy, the fourth device may optionally send the user policy to the terminal. After receiving the user policy, the terminal may conduct a PDU session based on the user policy, thereby achieving a PDU session in a regenerative access mode.

[0233] The first PCC rule may be applied to a PDU session in a backhaul type using a regenerative access mode. Optionally, the first PCC rule may include 5QI or QoS parameters in a backhaul type using a regenerative access mode, including UL-maximum bitrate, DL-maximum bitrate, UL-guaranteed bitrate, DL-guaranteed bitrate, ARP, and Priority Level.

[0234] When the fourth device determines the first PCC policy based on the access information or backhaul type information, optionally, when the access information includes the second information, and the second information includes ISL participation information (ISL hop count or delay), the fourth device may further calculate or determine, based on the ISL hop count or delay, 5QI or QoS parameters (such as PDB, priority), UL-maximum bitrate, DL-maximum bitrate, UL-guaranteed bitrate, DL-guaranteed bitrate, ARP, and Priority Level under the backhaul type of the regeneration access mode. For example, when the fourth device determines the PDB, the PDB may include the delay of the ISL link.

[0235] After determining the first PCC rule, the fourth device may optionally send the first PCC rule to the third device. After receiving the first PCC rule, the third device may determine the first QoS parameter based on the first PCC rule. For details, see the embodiment shown in FIG5 , which will not be described in detail here.

[0236] In the embodiment of the present application, since the fourth device can receive the access information and backhaul type information of the regeneration access mode sent by the first device or the third device, and determine the user policy or the first PCC rule based on the access information and the backhaul type information, it can obtain the PDU session policy under the regeneration access mode, thereby better implementing the PDU session under the regeneration access mode. Optionally, since the fourth device can send the first PCC rule to the third device via PCC, and the third device determines the first QoS parameter based on the first PCC rule, it can obtain QoS parameter information under the regeneration access mode, thereby implementing resource scheduling under the regeneration access mode.

[0237] In order to facilitate understanding of the information processing method provided in the embodiment of the present application, a more specific implementation method shown in Figures 7 to 11 will be used as an example for explanation below.

[0238] FIG7 is a schematic flowchart of establishing a PDU session in a regeneration access mode according to an embodiment of the present application, which may include the following steps.

[0239] Step 1: UE sends a PDU session establishment request to AMF.

[0240] Step 2: AMF obtains access information of the regeneration access method.

[0241] The access information may include first information, where the first information is used to indicate that the UE accesses through a regeneration access mode, where the regeneration access mode includes at least one of the following:

[0242] Accessed through a high-orbit satellite (GEO) regenerative access mode, indicating that the base station type of the non-ground base station is a high-orbit regenerative load type;

[0243] Accessed through the medium-orbit (MEO) satellite regenerative access mode, indicating that the base station type of the non-ground base station is the medium-orbit regenerative load type;

[0244] Accessed through a regenerative access method of a low-orbit satellite (LEO), indicating that the base station type of the non-ground base station is a low-orbit regenerative load type;

[0245] Accessed through regenerative access mode of other types of satellites (othersat), indicating that the base station type of the non-ground base station is other type of regenerative load type.

[0246] It should be noted that in the NB-IOT communication system, the base station type of non-ground base station can also be the following types:

[0247] NB-IOT regenerative payload type;

[0248] NB-IOT store and forward (S&F) type;

[0249] NB-IOT high track regenerative load type;

[0250] Types of track regenerative loads in NB-IOT;

[0251] NB-IOT low-orbit regenerative load type;

[0252] NB-IOT high-orbit store and forward type;

[0253] Track store and forward type in NB-IOT;

[0254] NB-IOT low-orbit store and forward type.

[0255] It should also be noted that the regeneration access mode may also be referred to as a regeneration access type or a regeneration load type.

[0256] The access information may further include second information, where the second information is used to indicate whether the UE has an ISL link involved in the regeneration access mode. If an ISL link is involved, the second information also includes the number of ISL hops or delay.

[0257] When the access information includes the first information, the AMF may obtain the first information from the RAN (see Figures 10 and 11). When the access information includes the second information, the AMF may obtain the second information from the RAN (see Figures 10 and 11), or determine the second information according to the second configuration information.

[0258] The second configuration information is the local configuration information of the AMF. When the AMF determines the second information based on 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, where the local configuration information includes a mapping relationship between the TAI and the second information. For example, if the ISL mapped to TAI#1 is two hops or the latency is 6ms, then the second information may be that the number of ISL hops is two hops or the latency is 6ms.

[0259] Step 3: AMF determines the backhaul type of the regeneration access method.

[0260] When the AMF determines the backhaul type of the regeneration access mode, in one implementation, it can be determined based on the first configuration information. The first configuration information is the local configuration information of the AMF, which may include at least one of the following:

[0261] The mapping between RAN ID and backhaul type;

[0262] The mapping relationship between TAI and return type.

[0263] When the AMF determines the backhaul type based on the above mapping relationship, for example, if RAN ID#1 is mapped to the LEO regenerative satellite backhaul type, the AMF can determine that the backhaul type of the current UE is the LEO regenerative satellite backhaul type. For another example, if TAI#1 is mapped to the LEO regenerative satellite backhaul type, the AMF can determine that the backhaul type of the current UE is the LEO regenerative satellite backhaul type.

[0264] In another implementation, the AMF may determine the backhaul type of the regeneration access mode based on the access information. Specifically, the backhaul type may include at least one of the following:

[0265] If the access information includes the first information and the first information is accessed through a regenerative access method of a high-orbit satellite (GEO), the backhaul type is GEO regenerative satellite backhaul; if the access information also includes the second information, the backhaul type is DYNAMIC GEO regenerative satellite backhaul;

[0266] If the access information includes the first information and the first information is accessed through a regenerative access method of a medium earth orbit (MEO) satellite, the backhaul type is MEO regenerative satellite backhaul; if the access information also includes the second information, the backhaul type is DYNAMIC MEO regenerative satellite backhaul;

[0267] If the access information includes first information and the first information is accessed through a regenerative access method of a low earth orbit (LEO) satellite, the backhaul type is LEO regenerative satellite backhaul; if the access information also includes second information, the backhaul type is DYNAMIC LEO regenerative satellite backhaul;

[0268] If the access information includes first information and the first information is accessed through a regenerative access method of other types of satellites (othersat), the backhaul type is othersat regenerative satellite backhaul; if the access information also includes second information, the backhaul type is DYNAMIC othersat regenerative satellite backhaul.

[0269] Step 4: AMF sends access information of the regeneration access mode or return type information to SMF.

[0270] Optionally, if the information of the return type does not include a dynamic return type, the access information sent by the AMF to the SMF may be the first information sent to the SMF; if the information of the return type includes a dynamic return type, the access information sent by the AMF to the SMF may be the second information sent to the SMF, or the first information and the second information.

[0271] Step 5: SMF sends a response message to AMF.

[0272] Step 6: The network performs the authentication and authorization process for the UE's PDU session.

[0273] Step 7: SMF sends access information of the regeneration access mode or backhaul type information to PCF.

[0274] For example, the SMF may send an NPcf_SMPolicyControl_Create message to the PCF, where the message carries access information or return type information.

[0275] Optionally, the information sent by SMF to PCF may be consistent with the information sent by AMF to SMF in step 4.

[0276] Step 8: PCF and SMF execute the session management policy (SM policy) establishment process.

[0277] Step 9: The PCF generates a first PCC rule according to the access information of the regeneration access mode or the backhaul type information.

[0278] The first PCC rule may be applied to a PDU session under a backhaul type of a regenerative access mode. Optionally, if the access information received by the PCF includes second information, the PCF may also consider the second information when generating the first PCC rule. The first PCC rule may include the following principles:

[0279] The First PCC Rule contains the following principles:

[0280] a) 5QI or QoS parameters (packet delay budget (PDB), priority), UL-maximum bitrate, DL-maximum bitrate, UL-guaranteed bitrate, DL-guaranteed bitrate, ARP, and Priority Level for backhaul using regenerative access;

[0281] b) If the second information is considered, the PCF may also calculate or determine the 5QI or QoS parameters (packet delay budget (PDB), priority), UL-maximum bitrate, DL-maximum bitrate, UL-guaranteed bitrate, DL-guaranteed bitrate, ARP, and priority level) for the backhaul type of the regenerative access mode based on the ISL hop count or latency information in the second information. For example, when determining the PDB, the PDB may include the latency of the ISL link.

[0282] Step 10: The PCF sends the first PCC rule to the SMF.

[0283] Step 11: SMF executes N4 session establishment.

[0284] Step 12: The SMF determines the first QoS parameter.

[0285] If steps 7-10 are performed, the SMF may determine the first QoS parameter based on the first PCC rule. If steps 7-10 are not performed, the SMF may determine the first QoS parameter based on the access information or backhaul type sent by the AMF and the locally configured policy information.

[0286] The first QoS parameter may include CN PDB, where 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 under the backhaul type of the regeneration access mode.

[0287] Step 13: SMF sends the first QoS parameter to AMF.

[0288] For example, SMF can send a Namf_Communication_N1N2MessageTransfer message to AMF, and the message carries the first QoS parameter.

[0289] Step 14: AMF forwards the first QoS parameter to RAN.

[0290] Step 15: AMF sends SMF's PDU session establishment acceptance response to UE.

[0291] Figure 8 is a schematic flowchart of the PCF generating a user policy according to an embodiment of the present application. During the UE policy association phase, the AMF may send the backhaul type of the regeneration access mode to the PCF, and the PCF may generate a user policy under the regeneration access mode, which may include the following steps.

[0292] Step 1: AMF sends access information or return type of regeneration access mode to PCF.

[0293] For example, the AMF may send an Npcf_UEPolicyControl_Create Request to the PCF, carrying access information or the return type of the regeneration access method.

[0294] Step 2: PCF sends a response message to AMF.

[0295] For example, PCF can send Npcf_UEPolicyControl_Create Responser to AMF.

[0296] Step 3: The PCF generates a user policy based on the access information or backhaul type of the regeneration access mode.

[0297] User policies can include URSPs. User policies can be applied to PDU sessions in a regenerative access backhaul mode. For example, the PCF configures slices in the RSD for regenerative access mode, such as DNN or SSC mode.
