[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410165851.5 filed in China on February 5, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to an access control method, an information sending method, an apparatus, a terminal, and a network-side device. Background Art

[0004] With the introduction of non-terrestrial networks (NTN) communication systems, there are currently both NTN and terrestrial networks (NTN) communication systems. Multiple NTN connection methods exist within NTN communication systems, including transparent load, regenerative load, and store-and-forward (S&F). Currently, NTN cells can only prohibit access by terminals without NTN capabilities. However, NTN-capable terminals may have different capabilities (e.g., only supporting transparent load or regenerative load). For terminals that do not support NTN connection via a particular method, if they reside in a cell that supports that method and attempt to obtain service, their normal registration will be rejected by network-side equipment. The terminal will then need to reselect another cell to reside in and attempt to register, resulting in delayed service acquisition for the terminal. Summary of the Invention

[0047] The network-side device 12 may include an access network device or a core network device, wherein the access network device may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node. Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home evolved Node B (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the relevant field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0049] NTN refers to a network or network segment that uses satellite or Unmanned Aircraft System (UAS) platforms for transmission. Compared with terrestrial communication systems, satellite-based non-terrestrial communication systems have a wider coverage area. Typical applicable scenarios include situations where ground base stations cannot be built or are damaged, such as continuous coverage in remote mountainous areas, deserts, oceans, and forests, and emergency communications when ground base stations are damaged due to natural disasters.

[0050] Satellites may include low earth orbiting (LEO) satellites, medium earth orbiting (MEO) satellites, geostationary earth orbiting (GEO) satellites and highly elliptical orbiting (HEO) satellites.

[0051] NTN systems include two types: transparent payload-based NTN communication systems and regenerative payload-based NTN communication systems. Considering only the deployment environment of the transparent payload-based NTN system, terminals, base stations, and core network equipment are all deployed on the ground, and communication data between terminals and network-side equipment is relayed via satellites in the air. In this system, satellites only forward data between base stations and terminals and do not decode or process this data. In the regenerative payload-based NTN communication system, satellites have some or all base station functions and can decode and process uplink or downlink data. As shown in Figure 2, the link between the satellite and the terminal is the service link, and the link between the satellite and the ground gateway is the feedback link (also called a feeder link in some cases).

[0052] Satellite S&F operations in systems accessed via satellite are intended to provide delay-tolerant communication services to terminals under satellite coverage with intermittent / temporary satellite connectivity (e.g., when the satellite is not connected to the terrestrial network through a feedback link or through an inter-satellite link (ISL)).

[0053] As shown in Figure 3, in the normal / default satellite operating mode, the signaling and data exchange between a terminal accessing the satellite and the remote terrestrial network requires that both the service link and the feeder link be activated simultaneously. This way, when the terminal interacts with the satellite via the service link, there is a continuous end-to-end connection path between the terminal, the satellite, and the terrestrial network.

[0054] In the S&F satellite mode of operation, the end-to-end exchange of signaling / data is now handled by a combination of two time-asynchronous steps (steps A and B in Figure 4). In step A, signaling / data is exchanged between the terminal and the satellite while the satellite is not connected to the terrestrial network (i.e., the satellite can operate a service link without an active feedback link). In step B, a connection is established between the satellite and the terrestrial network, enabling communication between the satellite and the terrestrial network. Thus, the satellite transitions from being connected to the terminal in step A to being connected to the terrestrial network in step B.

[0055] Below, in conjunction with the accompanying drawings, an access control method, information sending method, apparatus, terminal and network-side equipment provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0056] Please refer to FIG5 , which is a flow chart of an access control method provided in an embodiment of the present application. As shown in FIG5 , the method includes the following steps:

[0057] Step 501: The terminal obtains access control information of a cell;

[0058] Step 502: The terminal determines the cell status based on the access control information and terminal information.

[0059] The access control information is used to indicate at least one of the following: whether the cell is barred, whether the cell is prohibited from connecting to a non-terrestrial communication network (NTN), whether the cell is prohibited from connecting to the NTN via a transparent load, whether the cell is prohibited from connecting to the NTN via a regenerative load, whether the cell is prohibited from connecting to the NTN via an S&F mode, and a cell type of the cell;

[0060] The terminal information includes at least one of the following:

[0061] The capabilities of the terminal and the services of the terminal.

[0062] The above indication of whether a cell is prohibited can be understood to indicate whether the cell is prohibited or the cell is allowed;

[0063] The above indication of whether the cell is prohibited from connecting to the NTN can be understood as indicating that the cell is prohibited from connecting to the NTN or indicating that the cell is allowed to connect to the NTN;

[0064] The above indication of whether the cell is prohibited from connecting to the NTN via the transparent load can be understood as indicating that the cell is prohibited from connecting to the NTN via the transparent load or is allowed to connect to the NTN via the transparent load;

[0065] The above indication of whether the cell is prohibited from connecting to the NTN via the regeneration load can be understood as indicating whether the cell is prohibited from connecting to the NTN via the regeneration load or is allowed to connect to the NTN via the regeneration load;

[0066] The above indication of whether the cell is prohibited from connecting to the NTN via the S&F manner may be understood as an indication of whether the cell is prohibited from connecting to the NTN via the S&F manner or is allowed to connect to the NTN via the S&F manner.

[0067] The above access control information may be access control information sent by the network side device and received by the terminal.

[0068] The access control information of the cell may be obtained through the cell, that is, the terminal obtains the access control information of the cell itself through the cell. For example, the access control information is carried by System Information Block 1 (SIB1) or an NTN dedicated system message. The NTN dedicated system message includes SIB31 (for LTE scenarios, for providing satellite assistance information of the serving cell) or SIB19 (for NR scenarios, for providing satellite assistance information for NTN access).

[0069] Alternatively, obtaining the access control information of the cell may involve obtaining the access control information of the cell through a neighboring cell, where the neighboring cell is a neighboring cell of the terminal's serving cell. For example, the terminal obtains the access control information of the neighboring cell from a system message of the serving cell. For example, the access control information is carried in a cell reselection-related system message or an NTN-specific system message. The cell reselection-related system message may include SIB3, SIB4, and SIB5. The NTN-specific system message may carry SIB33 (used in LTE scenarios, for providing satellite assistance information of neighboring cells) or SIB19 (used in NR scenarios, for providing satellite assistance information for NTN access, which may include satellite assistance information of neighboring cells).

[0070] The above-mentioned access control information may explicitly or implicitly indicate at least one of the following: whether the cell is prohibited, whether the cell is prohibited from connecting to the non-terrestrial communication network NTN, whether the cell is prohibited from connecting to the NTN through a transparent load, whether the cell is prohibited from connecting to the NTN through a regenerative load, whether the cell is prohibited from connecting to the NTN through the S&F method, and the cell type of the cell.

[0071] The capability of the terminal may be a capability of supporting connection to the NTN, and the service of the terminal may be a service currently being carried out or to be carried out.

[0072] The above-mentioned determination of the cell status is to determine the cell status of the above-mentioned cell, wherein the cell status may include at least one of the following:

[0073] For details, see the following implementation methods: prohibited, allowed access, only supporting emergency services, allowing connection to NTN through regenerative load, allowing connection to NTN through S&F, etc.

[0074] In an embodiment of the present application, the above steps can enable the terminal to judge the cell status based on the access control information and the terminal information, and since the access control information is used to indicate whether the cell is prohibited from connecting to the non-terrestrial communication network NTN, whether the cell is prohibited from connecting to the NTN through a transparent load, whether the cell is prohibited from connecting to the NTN through a regenerative load, whether the cell is prohibited from connecting to the NTN through a store and forward S&F method, and at least one of the cell type of the cell, the terminal can judge the cell status, thereby avoiding the terminal from initiating registration with a cell that may be rejected by the network side device, thereby reducing the delay in the terminal obtaining service.

[0075] As an optional implementation manner, after the terminal determines the cell status, the terminal initiates registration with the cell to which access is allowed, and does not initiate registration with the prohibited cell.

[0076] As an optional implementation manner, if the terminal determines that the status of the cell is prohibited, the terminal reselects another cell.

[0077] As an optional implementation manner, the access control information includes at least one of the following:

[0078] first indication information, where the first indication information is used to indicate whether the cell is barred;

[0079] second indication information, where the second indication information is used to indicate at least one of whether the cell is prohibited from connecting to the NTN and whether the cell is prohibited from connecting to the NTN through a transparent load;

[0080] The third indication information is used to indicate at least one of the following:

[0081] a cell type of the cell, where the cell type is related to the NTN;

[0082] Whether the cell is prohibited from connecting to the NTN via regenerative load;

[0083] Whether the cell is prohibited from connecting to the NTN via the store and forward (S&F) mode.

[0084] It should be noted that the first indication information, the second indication information and the third indication information may be carried by different messages or by the same message.

[0085] For example, in a Long Term Evolution (LTE) scenario, the first indication information is carried via SIB1, a System Information Block 1-Broadcast Redirection (SIB1-BR) providing network redirection information, or a System Information Block 1-Narrowband (SIB1-NB) providing basic configuration information for a narrowband IoT network, such as via the cellAccessRelatedInfo IE in these messages. For example, the first indication information is at least one of the following: cellBarred, cellBarred-cell-specific Reference Signal (CRS), cellBarred-5G Core Network (5GC), or cellBarred-5GC-CRS. A cellBarred value of barred indicates that the cell is barred, while a value of notBarred indicates that the cell is not barred. cellBarred-5GC indicates whether the cell is barred from connecting to the 5GC. A value of barred indicates that the cell is barred from connecting to the 5GC, while a value of notBarred indicates that the cell is allowed to connect to the 5GC.

[0086] For another example, for a New Radio (NR) scenario, the first indication information is carried by a Master Information Block (MIB), such as cellBarred, which is used to indicate whether the cell is barred. A value of barred means that the cell is barred.

[0087] For another example: for the LTE scenario, the second indication information is carried through SIB1 / SIB1-BR / SIB1-NB (for example, carried through cellAccessRelatedInfo-NTN IE), for example, the first indication information includes at least one of the cellBarred-NTN field and cellBarredNTN-5GC, wherein cellBarred-NTN is used to indicate whether the cell is prohibited from connecting to NTN or to indicate that the cell is prohibited from connecting to the Evolved Packet Core (EPC) through NTN, and the value barred means that the cell is prohibited from connecting to NTN, and cellBarredNTN-5GC is used to indicate whether the cell is prohibited from connecting to 5GC through NTN, and the value barred means that the cell is prohibited from connecting to 5GC through NTN.

[0088] For another example: For the NR scenario, the second indication information is carried by SIB1. For example, the CellBarredNTN field is used to indicate whether the cell is prohibited from connecting to NTN. The value barred means that the cell is prohibited from connecting to NTN, and the value notBarred means that the cell is allowed to connect to NTN.

[0089] The third indication information may include one or more indication information to indicate at least one of the following:

[0090] a cell type of the cell, where the cell type is related to the NTN;

[0091] Whether the cell is prohibited from connecting to the NTN via regenerative load;

[0092] Whether the cell is prohibited from connecting to the NTN via S&F.

[0093] The cell type may include at least one of the following:

[0094] Regeneration load type, high orbit regeneration load type, medium orbit regeneration load type, low orbit regeneration load type, High Altitude Platform Station (HAPS) regeneration load type, S&F type, high orbit S&F type, medium orbit S&F type, low orbit S&F type, HAPS S&F type.

[0095] The above-mentioned regenerative load type may be indicated by regenerative load type indication information (regenerative payload indication), and the indication information may be used to indicate that the cell is a cell covered by satellite based on regenerative load.

[0096] The above-mentioned S&F type can be indicated by S&F type indication information (S&F indication), and the indication information can be used to indicate that the cell is a cell covered by a satellite with S&F capability.

[0097] Other cell types can also be handled through corresponding indication information, which will not be described in detail here.

[0098] Whether the cell is prohibited from connecting to the NTN via the regeneration load may refer to whether the cell is prohibited from connecting to the NTN via at least one of the regeneration load, the high orbit regeneration load, the medium orbit regeneration load, the low orbit regeneration load, and the HAPS regeneration load.

[0099] Whether the cell is prohibited from connecting to the NTN through the S&F mode may refer to whether the cell is prohibited from connecting to the NTN through at least one of the S&F mode, the high-orbit S&F mode, the medium-orbit S&F mode, the low-orbit S&F mode, and the HAPS S&F mode.

[0100] In the above implementation, at least one of the first indication information, the second indication information, and the third indication information can improve the indication accuracy of the access control information, so that the terminal can perform more accurate cell status judgment.

[0101] Optionally, the third indication information includes at least one of the following:

[0102] At least one fourth indication information, the fourth indication information being used to indicate at least one of the following: whether the cell is prohibited from connecting to the NTN to provide a target service through a regeneration load, and whether the cell is prohibited from connecting to the NTN to provide a target service through an S&F mode;

Different sixth indication information can be used to indicate different access identifiers, and the correspondence can be one-to-one, that is, one sixth indication information corresponds to one AI, and the correspondence can also be one-to-many, that is, one fifth indication information corresponds to multiple AIs.

[0112] If the third indication information includes the seventh indication information and the eighth indication information, it means that two indication information are used to indicate the information related to the regeneration load and the information related to S&F respectively. The seventh indication information is used to indicate the information related to the regeneration load, and the eighth indication information is used to indicate the information related to S&F.

[0113] If the third indication information includes one indication information, it means that the indication information is used to indicate the information related to the regeneration load and the information related to the S&F, that is, the access control of the regeneration load and the access control of the S&F share one indication information.

[0114] At least one item of the fourth to eighth indication information can be used to implement a more fine-grained access control indication, further improving the accuracy of cell status judgment.

[0124] The second capability includes at least one of the following:

[0125] Supports connection to NTN via regenerative load;

[0126] Supports connection to NTN via S&F mode.

[0127] The terminal determining the cell status based on the second indication information may include at least one of the following:

[0128] In a case where the second indication information indicates that the cell is prohibited from connecting to the NTN, the terminal considers that the cell is prohibited or considers that the cell only supports emergency services;

[0129] In a case where the second indication information indicates that the cell is allowed to connect to the NTN, the terminal considers that the cell is allowed to be accessed;

[0130] In a case where the second indication information indicates that the cell is prohibited from connecting to the NTN through a transparent load, the terminal considers that the cell is prohibited or considers that the cell only supports emergency services;

[0131] When the second indication information indicates that the cell is allowed to connect to the NTN through a transparent load, the terminal considers that the cell allows access. For example: if the value of the second indication information is barred, the cell is considered to be prohibited. For example, for the LTE scenario, the value of cellBarred-NTN is barred, and the terminal considers that the cell is prohibited from connecting to the NTN, and may also consider that it is prohibited from connecting to the EPC through the NTN; the value of cellBarredNTN-5GC is barred. The terminal considers that the cell is prohibited from connecting to the 5GC through the NTN; if the value of the second indication information is notBarred, the cell is considered not to be prohibited or the cell is considered to allow access.

[0132] The terminal determining the cell status based on the first indication information may include at least one of the following:

[0140] In some embodiments, when the access control information includes the second indication information, the terminal with the second capability believes that the cell is prohibited or that the cell only supports emergency services. It can be understood that the presence of the second indication information means that the cell type is a transparent load type, and the terminal with the second capability can decode the second indication information.

[0141] In some embodiments, when the access control information includes the second indication information, the terminal with the second capability determines the cell state based on the first indication information.

[0362] When the sixth indication information indicates that the terminal in the cell is prohibited from applying the target access identifier to connect to the NTN through the regeneration load and the terminal applies the target access identifier, the terminal considers that the cell is prohibited from connecting to the NTN through the regeneration load;

[0364] When the sixth indication information indicates that the terminal applying the target access identifier to the cell is prohibited from connecting to the NTN through the S&F mode and the terminal applies the target access category, the terminal considers that the cell is prohibited from connecting to the NTN through the S&F mode;

[0370] or,

[0371] In a case where the cell type of the cell is a transparent load type, the access control information does not include the third indication information.

[0384] The above-mentioned normal services may be normal services defined by a protocol or normal services configured by a network-side device.

[0385] In this implementation, multiple ways of connecting to the NTN can be supported to improve the access performance of the terminal.

[0386] In an embodiment of the present application, a terminal obtains access control information of a cell; the terminal determines the cell status based on the access control information and terminal information; the access control information indicates at least one of the following: whether the cell is barred, whether the cell is barred from connecting to a non-terrestrial communication network (NTN), whether the cell is barred from connecting to the NTN via a transparent load, whether the cell is barred from connecting to the NTN via a regenerative load, whether the cell is barred from connecting to the NTN via a store-and-forward (S&F) method, and the cell type of the cell; and the terminal information includes at least one of the following: the terminal's capabilities and the terminal's services.

[0418] It should be noted that this embodiment is an implementation of the network side device corresponding to the embodiment shown in Figure 3. Its specific implementation can refer to the relevant description of the embodiment shown in Figure 3. In order to avoid repeated description, this embodiment will not be repeated.

[0419] The following describes the method provided in the embodiments of the present application through multiple examples:

[0420] Example 1:

[0421] This embodiment mainly describes that a transparent load type NTN cell blocks access by terminals that do not support transparent load and allows access by terminals that support transparent load. The NTN cell may be a legacy cell, in which MIB cellBarred=barred and SIB1 CellBarred=not barred may be used.

[0422] The terminals in this embodiment may include terminals that only support regenerative load and terminals that do not support transparent load.

[0423] This embodiment may include the following steps:

[0424] Step 1: The terminal obtains the access control information of the cell.

[0425] The terminal obtains the access control information of the cell in at least one of the following ways:

[0426] The access control information of the cell is obtained through the cell, that is, the terminal obtains the access control information of the cell itself through the cell. For example, the access control information is carried by SIB1 (for example, contained in the cellAccessRelatedInfo IE) and NTN dedicated system messages. NTN dedicated system messages include SIB31 (for LTE scenarios, used to provide satellite assistance information of the serving cell) and SIB19 (for NR scenarios, used to provide satellite assistance information for NTN access).

[0427] The access control information of the above-mentioned cell is obtained through a neighboring cell, where the neighboring cell is the service cell of the terminal, and the neighboring cell of the above-mentioned cell, that is, the terminal obtains the access control information of the neighboring cell from the system message of the service cell. For example, the access control information is carried by a cell reselection-related system message and an NTN-dedicated system message. The cell reselection-related system message includes SIB3, SIB4 (such as IntraFreqNeighCellInfo IE), SIB5 (such as InterFreqNeighCellInfo IE), and the NTN-dedicated system message carries SIB33 (for LTE scenarios, for providing satellite assistance information of neighboring cells), SIB19 (for NR scenarios, for providing satellite assistance information for NTN access, which may include satellite assistance information of neighboring cells).

[0428] The access control information is used to indicate at least one of the following:

[0429] First indication information, the first indication information is used to indicate whether the cell is barred; for example, for LTE scenarios, the first indication information is carried through SIB1 / SIB1-BR / SIB1-NB (for example, carried through cellAccessRelatedInfo IE), such as cellBarred (used to indicate whether the cell is barred, a value of barred means the cell is barred), cellBarred-CRS, cellBarred-5GC (used to indicate whether the cell is barred from connecting to 5GC, a value of barred means the cell is barred from connecting to 5GC), and at least one of cellBarred-5GC-CRS. For NR scenarios, the first indication information is carried through MIB, such as cellBarred (used to indicate whether the cell is barred, a value of barred means the cell is barred);

[0430] The second indication information is used to indicate whether the cell is prohibited from connecting to the NTN; for example, for the LTE scenario, the second indication information is carried by SIB1 / SIB1-BR / SIB1-NB (for example, carried by cellAccessRelatedInfo-NTN IE), such as cellBarred-NTN (used to indicate whether the cell is prohibited from connecting to the NTN, and the value barred means that the cell is prohibited from connecting to the NTN), and for example, may also include cellBarredNTN-5GC (used to indicate whether the cell is prohibited from connecting to the 5GC through the NTN, and the value barred means that the cell is prohibited from connecting to the 5GC through the NTN); for the NR scenario, the second indication information is carried by SIB1, such as CellBarredNTN (used to indicate whether the cell is prohibited from connecting to the NTN, and the value barred means that the cell is prohibited from connecting to the NTN, and the value notBarred means that the cell is allowed to connect to the NTN).

[0431] Step 2: The terminal determines the cell status based on the access control information. The terminal's actions include at least one of the following:

[0432] The terminal without NTN capability determines whether the cell is prohibited based on the first indication information, and the terminal's behavior includes at least one of the following:

[0433] If the value of the first indication information is barred, the cell is considered to be barred;

[0434] If the value of the first indication information is notBarred, it is considered that the cell is not barred.

[0435] The terminal with the first capability determines the cell status based on the second indication information, and the terminal's behavior includes at least one of the following:

[0436] If the second indication information of the cell exists, the terminal with the first capability ignores the first indication information;

[0437] The terminal with the first capability determines the cell status based on the second indication information, including at least one of the following:

[0438] If the value of the second indication information is barred, the cell is considered to be barred. For example, in the LTE scenario, if the value of cellBarred-NTN is barred, the terminal considers that the cell is prohibited from connecting to NTN (it can also be considered that it is prohibited from connecting to EPC through NTN); if the value of cellBarredNTN-5GC is barred, the terminal considers that the cell is prohibited from connecting to 5GC through NTN;

[0439] If the second indication information is set to notBarred, the cell is considered not to be barred. For example, in the NR scenario, if the value of cellBarredNTN is notBarred, the terminal considers that the cell is allowed to connect to NTN.

[0440] If the second indication information does not exist and the first condition is met, the cell is considered to be barred, where the first condition includes at least one of the following:

[0441] Access to the above cells is to connect to the NTN through transparent load;

[0442] The cell type of the cell is a transparent load type;

[0443] Initiate transparent load related services.

[0444] For example, for the NR scenario, if the cell is accessed in order to connect to the NTN through a transparent load, and cellBarredNTN does not exist, the terminal considers that the cell is prohibited from connecting to the NTN. It is understandable that, in another implementation, a cell with a transparent load type must include the second indication information.

[0445] The terminal having the first capability is a terminal supporting communication related to transparent load, and the first capability may include at least one of the following:

[0446] Have NTN capability;

[0447] Supports connection to NTN via transparent load;

[0448] Initiate transparent load-based services;

[0449] Connection to NTN via regenerative loads is not supported, including connection to NTN based on high-orbit / low-orbit / mid-orbit regenerative loads.

[0450] Do not initiate services based on regenerative loads;

[0451] Connection to NTN via S&F is not supported, including connection to NTN based on high orbit, medium orbit, or low orbit S&F.

[0452] No S&F-based business is initiated.

[0453] The behavior of the terminal with the second capability includes at least one of the following:

[0454] The cell status is determined based on the first indication information. For example, if the value of cellBarred is barred, the terminal considers that the cell is barred. It is understandable that the terminal with the second capability cannot decode the second indication information. The method may also include, when the cell is an NTN cell of transparent load type, the terminal determines the cell status based on the first indication information. In one implementation, the NTN cell of transparent load type sets the value of the first indication information (e.g., cellBarred in MIB) to barred and sets the value of the second indication information (e.g., cellBarredNTN in SIB1) to notBarred.

[0455] If the second indication information exists, the terminal considers the cell to be prohibited. In other words, the existence of the second indication information means that the cell type is a transparent load type. It is understood that a terminal with the second capability can decode the second indication information;

[0456] If the second indication information exists, the terminal considers that the cell only supports emergency services.

[0457] The terminal having the second capability is a terminal supporting communication related to regenerative load or a terminal supporting communication related to S&F, and the second capability includes at least one of the following:

[0458] Have NTN capability;

[0459] Connection to NTN via transparent load is not supported;

[0460] Do not initiate transparent load-based services;

[0461] Supporting connection to the NTN via a regenerative load, including supporting at least one of connecting to the NTN via a high-orbit / low-orbit / medium-orbit regenerative load. It is understood that connecting to the NTN via a regenerative load means connecting to the NTN via a regenerative load when both the service link and the feeder link are available;

[0463] Supporting connection to NTN via S&F mode, including supporting at least one of connecting to NTN via high orbit / medium orbit / low orbit S&F mode. It can be understood that connecting to NTN via S&F mode means connecting to NTN when the feeder link is unavailable but the service link is available;

[0464] Initiate S&F-based business (i.e. S&F-related business).

[0465] The terminal considering the cell to be prohibited may include: not allowing the terminal to select / reselect the cell; in some implementations, selecting / reselecting the cell is not allowed even for emergency services.

[0466] The terminal considering that the cell is not barred may include: the terminal considering the cell as a candidate cell for cell selection / reselection.

[0467] Example 2:

[0468] This embodiment mainly describes how an NTN cell with a regenerative load type blocks access by terminals that do not support regenerative load, while allowing access by terminals that do support regenerative load. Furthermore, when a feedback link is unavailable, access by terminals that do not support S&F is blocked, while access by terminals that do support S&F is allowed. In this embodiment, the regenerative load type and the S&F type share the same indication information. The following steps are included:

[0469] Step 1: The terminal obtains the access control information of the cell

[0470] The access control information is used to indicate at least one of the following:

[0471] First indication information (same as in Example 1);

[0472] Second indication information (same as in Example 1);

[0473] The third indication information is used to indicate at least one of the following:

[0474] Cell type information, where the cell type information includes at least one of the following:

[0475] Regenerative load type indication information; such as regenerative payload indication; it can be understood that the indication information is used to indicate that the cell is a cell covered by a satellite based on a regenerative load;

[0476] S&F type indication information; such as S&F indication; it can be understood that the indication information is used to indicate that the cell is a cell covered by a satellite with S&F capability;

[0477] High-orbit regenerative load type indication information, such as GEO regenerative load indication (GEO regenerative payload indication); it can be understood that the indication information is used to indicate that the cell is a cell covered by a satellite based on a high-orbit regenerative load;

[0478] Mid-rail regenerative load type indication information;

[0479] Low-orbit regenerative load type indication information;

[0480] HAPS regenerative load type indication information;

[0481] High orbit S&F type indication information;

[0482] Mid-rail S&F type indication information;

[0483] Low Earth Orbit S&F type indication information;

[0484] HAPS S&F type indication information;

[0485] Whether the cell prohibits a first type of connection, where the first type includes at least one of the above cell types, such as CellBarred-SF (used to indicate whether the cell prohibits connection to the NTN based on the S&F mode), or CellBarred-regenerative (used to indicate whether the cell prohibits connection to the NTN through regenerative load);

[0486] It can be understood that a cell of transparent load type will not provide the third indication information.

[0487] Step 2: The terminal determines the cell status based on the access control information, including at least one of the following:

[0488] The terminal without NTN capability determines the cell status based on the first indication information;

[0489] The terminal with the first capability determines the cell status based on the second indication information, and the terminal's behavior includes at least one of the following:

[0490] If the second indication information of the cell exists, the terminal with the first capability ignores the first indication information;

[0491] The terminal with the first capability determines the cell status based on the second indication information, wherein the terminal with the first capability determines the cell status based on the second indication information includes at least one of the following:

[0492] If the value of the second indication information is barred, the cell is considered to be barred. For example, in the LTE scenario, if the value of cellBarred-NTN is barred, the terminal considers that the cell is prohibited from connecting to NTN (it can also be considered that it is prohibited from connecting to EPC through NTN); if the value of cellBarredNTN-5GC is barred, the terminal considers that the cell is prohibited from connecting to 5GC through NTN;

[0493] If the second indication information is set to notBarred, the cell is considered not to be barred. For example, in the NR scenario, if the value of cellBarredNTN is notBarred, the terminal considers that the cell is allowed to connect to NTN.

[0494] It can be understood that if a cell of the regenerative load type provides the second indication information, the second indication information is used to instruct the cell to prohibit connecting to the NTN via the transparent load (for example, the value of cellBarredNTN is barred);

[0495] If the second indication information does not exist and the first condition is met, the cell is considered to be barred, and the first condition includes at least one of the following:

[0496] Access to the above cells is to connect to the NTN through transparent load;

[0497] The type of the cell is a transparent load type.

[0498] For example, for the NR scenario, if the access is to connect to the NTN through transparent load, and cellBarredNTN does not exist, the terminal considers that the cell is prohibited from connecting to the NTN. It can be understood that, in another implementation, the cell type of the transparent load type must include the second indication information.

[0499] The terminal with the second capability determines the cell status based on the third indication information, and the terminal's behavior includes at least one of the following:

[0500] If the third indication information exists, the terminal ignores the first indication information, wherein ignoring the first indication information includes the terminal not performing the behavior indicated by the first indication information; additionally, if the third condition is met, if the third indication information exists, the terminal ignores the first indication information;

[0501] If the third indication information exists, the terminal ignores the second indication information. It can be understood that the terminal is capable of decoding the second indication information. Additionally, if the third condition is met, if the third indication information exists, the terminal ignores the second indication information.

[0502] If the third indication information exists, the terminal considers that the cell allows connection to the NTN via the regeneration load. Connection to the NTN via the regeneration load includes: the feeder link is available (supporting normal services) and the feeder link is unavailable (i.e., connection to the NTN based on the S&F operation mode is allowed and only services related to the S&F operation mode are supported). Additionally, if the third condition is met, if the third indication information exists, the terminal considers that the cell allows connection to the NTN via the regeneration load.

[0503] If the third indication information is set to the first value, the terminal considers that the cell allows connection to the NTN via the S&F mode. The first value includes any one of the following: notBarred, supports S&F type, supports high orbit S&F type, supports medium orbit S&F type, supports low orbit S&F type, supports HAPS S&F type, and does not support normal mode;

[0504] If the value of the third indication information is the second value, the terminal believes that the cell is prohibited from connecting to the NTN via the S&F method (or only allows connection to the NTN based on the normal operation mode), or the terminal believes that the cell only supports emergency services based on the S&F method. The second value includes any one of the following: barred, does not support S&F type, supports normal mode, supports high orbit normal mode, supports medium orbit normal mode, supports low orbit normal mode, and supports HAPS normal mode.

[0505] It can be understood that during the movement of the satellite, because the satellite will experience multiple changes of feeder link available → feeder link unavailable → feeder link available, the value of the third indication information will experience the change of first value -> second value -> first value...

[0506] It can be understood that, in one implementation, a cell of the regeneration load type / S&F type must include the third indication information;

[0507] If the third indication information does not exist, the terminal considers that the cell is prohibited from connecting to the NTN through the regeneration load, and the connection to the NTN through the regeneration load includes: the feeder link is available (supporting normal services) and the feeder link is unavailable (i.e., allowing connection to the NTN based on the S&F operation mode and only supporting services related to the S&F operation mode); in addition, if the third condition is met, if the third indication information does not exist, the terminal considers that the cell is prohibited from connecting to the NTN through the regeneration load.

[0508] The third condition is related to connecting to the NTN via a regenerative load or connecting to the NTN via a S&F mode, and includes at least one of the following:

[0509] The access to the above cells is to connect to the NTN through regenerative load;

[0510] The cell type is one of a regenerative load type, a high orbit regenerative load type, a medium orbit regenerative load type, a low orbit regenerative load type, and a HAPS regenerative load type;

[0511] Initiate renewable load related business;

[0512] Access to the above cells is to connect to NTN through S&F;

[0513] Access to the above-mentioned cells is for obtaining S&F related services;

[0514] The cell type is one of S&F type, high orbit S&F type, medium orbit S&F type, low orbit S&F type, and HAPS S&F type;

[0515] Initiate S&F related businesses.

[0516] Example 3:

[0517] This embodiment mainly describes how an NTN cell with a regeneration load type blocks access by terminals that do not support regeneration load, but allows access by terminals that do support regeneration load. When the feedback link is unavailable, access by terminals that do not support S&F is blocked, but access by terminals that do support S&F is allowed. The regeneration load type and S&F type are each indicated by two pieces of information. The following steps are included:

[0518] Step 1: The terminal obtains the access control information of the cell.

[0532] The eighth indication information is used to indicate S&F related information, including at least one of the following:

[0533] The S&F cell type information includes at least one of the following:

[0540] Step 2: The terminal determines the cell status based on the access control information, including at least one of the following:

[0541] The terminal without NTN capability determines the cell status based on the first indication information;

[0542] The terminal with the first capability determines the cell state based on the second indication information (same as in the second embodiment); it can be understood that, if a cell of the regenerative load type (both the service link and the feeder link are available) provides the second indication information, the second indication information is used to indicate that the cell is prohibited from connecting to the NTN through the transparent load (for example, the value of cellBarredNTN is barred); if a cell of the S&F type (the service link is available and the feeder link is unavailable) provides the second indication information, the second indication information is used to indicate that the cell is prohibited from connecting to the NTN through the transparent load (for example, the value of cellBarredNTN is barred);

[0543] The terminal with the third capability determines the cell status based on the seventh indication information, and the terminal's behavior includes at least one of the following:

[0544] If the seventh indication information exists, the terminal ignores the first indication information; additionally, if the fifth condition is met, the terminal performs the aforementioned behavior, i.e., determines the cell status based on the seventh indication information;

[0545] If the seventh indication information exists, the terminal ignores the second indication information; additionally, if the fifth condition is met, the terminal performs the aforementioned behavior, i.e., determines the cell status based on the seventh indication information;

[0546] If the seventh indication information is present, the terminal behavior includes at least one of the following:

[0547] Additionally, if the fifth condition is met, the terminal performs the aforementioned actions, including at least one of the following:

[0548] If the value of the seventh indication information is the third value, the terminal considers that the cell allows connection to the NTN through the regeneration load, and the regeneration load includes the case where both the service link and the feeder link are available (that is, the service is provided through the normal satellite operation mode). For example, the third value is notBarred, supporting regeneration load type, supporting high orbit regeneration load type, supporting medium orbit regeneration load type, supporting low orbit regeneration load type, supporting HAPS regeneration load type or supporting normal mode;

[0549] If the value of the seventh indication information is the fourth value, the terminal believes that the cell is prohibited from connecting to the NTN through the regeneration load, or the terminal believes that the cell is only allowed to provide emergency services through the regeneration load, and the regeneration load includes the case where both the service link and the feeder link are available (that is, the service is provided through the normal satellite operation mode). For example, the fourth value is barred, which means that the regeneration load type is not supported, the high orbit regeneration load type is not supported, the medium orbit regeneration load type is not supported, the low orbit regeneration load type is not supported, the HAPS regeneration load type is not supported, or the normal mode is not supported;

[0550] If the seventh indication information does not exist, the terminal considers that the cell is prohibited from connecting to the NTN via the regeneration load, or the terminal considers that the cell is only allowed to provide emergency services via the regeneration load. The regeneration load includes the case where both the service link and the feeder link are available (i.e., providing services via the normal satellite operation mode).

[0560] If the value of the eighth indication information is the fifth value, the terminal considers that the cell allows connection to the NTN via the S&F mode. For example, the fifth value is notBarred, supports S&F type, supports high orbit S&F type, supports medium orbit S&F type, supports low orbit S&F type, supports HAPS S&F type, supports S&F mode, or does not support normal mode;

[0561] If the value of the eighth indication information is the fifth value, the terminal considers that the cell is prohibited from connecting to the NTN via the S&F mode or the terminal considers that the cell is only allowed to provide emergency services via S&F. For example, the fourth value is barred, indicating that the S&F type is not supported, the high orbit S&F type is not supported, the medium orbit S&F type is not supported, the low orbit S&F type is not supported, the HAPS S&F type is not supported, or the S&F mode is not supported.

[0562] If the eighth indication information does not exist, the terminal considers that the cell is prohibited from connecting to the NTN via the S&F mode, or the terminal considers that the cell is only allowed to provide emergency services via S&F.

[0580] Example 4:

[0581] In this embodiment, if the cell allows the provision of S&F services, access control is performed at a granularity of per service type.

[0582] Taking the third indication information in Example 2 as an example, the third indication information in Example 2 includes at least one of the following:

[0583] At least one fourth indication information, at least one fifth indication information, and at least one sixth indication information.

[0584] The fourth indication information includes information corresponding to a service type, wherein the service type includes emergency services, high priority access, MT Access, mo-Signalling, mo-Data, delay-tolerant access-v1020, mo-Voice Call-v1280, delay-sensitive services, conversational services, streaming services, interactive services, and background services. The high priority access mentioned above is related to AC 11..15.

[0585] The fifth indication information includes information corresponding to AC;

[0586] The sixth indication information includes information corresponding to AI;

[0587] The above correspondence may be one-to-one, that is, one fourth indication information, fifth indication information, and sixth indication information correspond to one service type, AC, and AI respectively;

[0588] Alternatively, the above correspondence may also be a one-to-many relationship, that is, one fourth indication information, fifth indication information, and sixth indication information correspond to multiple service types, multiple ACs, and multiple AIs, respectively.

[0589] The terminal determines the cell status based on the service type, AC or AI of the terminal, and at least one fourth indication information, at least one fifth indication information, or at least one sixth indication information, including at least one of the following:

[0590] If the value of the fourth indication information corresponding to the service type of the terminal is the sixth value, the terminal considers that the cell allows connection to the NTN in the S&F mode. For example, the sixth value is used to indicate that the cell allows connection to the NTN in the S&F mode to obtain a certain service / group of services, and the cell allows a certain service / group of services to connect to the NTN in the S&F mode;

[0591] If the value of the fourth indication information corresponding to the service type of the terminal is the seventh value, the terminal considers that the cell does not allow / forbids connecting to the NTN in the S&F mode. For example, the seventh value is used to indicate that the cell does not allow connecting to the NTN in the S&F mode to obtain a certain service / group of services, and the cell does not allow / forbids a certain service / group of services to connect to the NTN in the S&F mode;

[0592] If the value of the fifth indication information corresponding to the AC of the terminal is the eighth value, the terminal considers that the cell allows the terminal to connect to the NTN in the S&F mode. For example, the eighth value is used to indicate that the cell allows the terminal using a certain / a certain group of ACs to connect to the NTN in the S&F mode. The cell allows the terminal using a certain / a certain group of ACs to connect to the NTN in the S&F mode.

[0593] If the value of the fifth indication information corresponding to the AC of the terminal is the ninth value, the terminal considers that the cell does not allow / forbids connecting to the NTN in the S&F mode. For example, the ninth value is used to indicate that the cell does not allow a certain AC / a certain group of ACs to connect to the NTN in the S&F mode, and the cell does not allow / forbids terminals using a certain AC / a certain group of ACs to connect to the NTN in the S&F mode.

[0594] If the value of the fifth indication information corresponding to the terminal's AI is the tenth value, the terminal considers that the cell allows the terminal to connect to the NTN in the S&F mode. For example, the tenth value is used to indicate that the cell allows the terminal applying a certain / a certain group of AIs to connect to the NTN in the S&F mode. The cell allows the terminal applying a certain / a certain group of AIs to connect to the NTN in the S&F mode.

[0595] If the value of the fifth indication information corresponding to the terminal's AI is the eleventh value, the terminal considers that the cell does not allow / prohibits connecting to the NTN via the S&F mode. For example, the eleventh value is used to indicate that the cell does not allow the use of a certain AI / group of AIs to connect to the NTN via the S&F mode. The cell does not allow / prohibit terminals using a certain AI / group of AIs to connect to the NTN via the S&F mode.

[0596] The above-mentioned terminal determines the status of the cell by the access stratum (AS) or the non-access stratum (NAS). If it is performed by the AS, the NAS indicates the service type / AC / AI of the AS terminal; if it is performed by the NAS, the AS indicates the above-mentioned fourth indication information, the fifth indication information or the sixth indication information, and its associated service type / AC / AI, and the NAS indicates whether the AS cell is allowed to connect to the NTN via the S&F method.

[0597] Taking the eighth indication information in Example 3 as an example, the eighth indication information in Example 3 includes at least one of the following:

[0598] At least one fourth indication information, at least one fifth indication information, and at least one sixth indication information.

[0599] The fourth indication information includes information corresponding to the service type;

[0600] The fifth indication information includes information corresponding to AC;

[0601] The sixth indication information includes information corresponding to the AI;

[0602] The terminal determines the cell state based on the service type, AC or AI of the terminal, and at least one fourth indication information, at least one fifth indication information, or at least one sixth indication information. For the specific determination method, please refer to the above corresponding content of this embodiment and will not be repeated here.

[0603] Similarly, the above-mentioned terminal determines the status of the cell can be executed by AS or NAS. If executed by AS, NAS indicates the service type / AC / AI of the AS terminal; if executed by NAS, AS indicates the above-mentioned fourth indication information, fifth indication information or sixth indication information, and its associated service type / AC / AI, and NAS indicates whether the AS cell is allowed to connect to the NTN via S&F.

[0604] In the embodiment of the present application, the terminal determines the cell status based on the terminal capability / cell type, including but not limited to:

[0605] Determine whether the terminal is allowed to access the NTN cell of transparent load type based on the terminal capability (whether it supports the transparent load NTN system) and the legacy access control indication;

[0606] A third indication information is introduced: based on the terminal capabilities and a third indication information, whether the NTN cell of the regeneration load type is allowed to access is determined. Furthermore, if the feedback link is unavailable, whether the S&F cell is allowed to access is determined based on the terminal capabilities and the new indication information;

[0607] The seventh indication information and the eighth indication information are introduced: whether the NTN cell of the regeneration load type is allowed to access is determined based on the terminal capability and the seventh indication information or the eighth indication information; whether the S&F cell (feedback link unavailable) is allowed to access is determined based on the terminal capability and the seventh indication information or the eighth indication information;

[0608] If the cell allows S&F services, access control is implemented per service type.
