[0044] Before describing the embodiments of this application, the following briefly introduces the related technologies:

[0045] I. NTN Communication System

[0046] Figure 2 Fig. shows the deployment scenario of a typical NTN communication system (also known as a satellite communication system). As Figure 2 shown, user equipment (UE, i.e., the terminal), base stations, and core network equipment are all deployed on the ground, and the communication data between the terminal and the network equipment is relayed via satellites in the air. The link between the terminal and the satellite is called the service link, and the link between the satellite and the terrestrial gateway is called the feeder link. In some scenarios, such as low Earth orbit (LEO) satellites (referred to as low-orbit satellites or low-orbit satellites for short), due to the movement of the satellite, the service link or the feeder link may switch. For service link switching, the serving satellite for all UEs within a cell needs to switch from one satellite to another. For feeder link switching, a certain satellite needs to switch from one terrestrial gateway to another terrestrial gateway.

[0047] Currently, two types of NTN communication systems have been proposed: one is the NTN communication system based on transparent payload, and the other is the NTN communication system based on regenerative payload. In the 3rd Generation Partnership Project (3GPP) Release 17 (R17) and Release 18 (R18), only the NTN communication system based on transparent payload is considered. In the NTN communication system based on transparent payload, the satellite is only used to forward the data between the base station and the terminal, and does not decode and process this data. For the NTN communication system based on regenerative payload, the satellite has some or all of the base station functions and can decode and process uplink data or downlink data. Exemplarily, if the satellite has all the functions of the access network, the access network equipment can be called the on-satellite access network equipment or the on-satellite base station equipment. In popular terms, it can also be called the base station on the satellite. In this case, the function of the centralized unit (CU) of the access network is called the on-satellite CU of the access network, and the function of the distributed unit (DU) of the access network is called the on-satellite DU of the access network. If the satellite has the CU function of the access network, the CU of the access network can be called the on-satellite CU of the access network equipment. In popular terms, it can also be called the CU on the satellite. If the satellite has the DU function of the access network, the DU of the access network can be called the on-satellite DU of the access network equipment. In popular terms, it can also be called the DU on the satellite.

[0048] II. Store and Forward (S&F) Communication Mode

[0049] In the NTN communication system, to enable data or signaling interaction between the terminal and the terrestrial network, it is necessary to ensure that the service link and the feeder link remain connected simultaneously, as Figure 3 shown.

[0050] However, in some cases, such as in the initial stage of satellite network deployment, it cannot be guaranteed that the service link and the feeder link can remain connected simultaneously. To support data transmission (such as delay-tolerant service data), a store-and-forward communication mode is proposed, as Figure 4 shown. Taking the uplink data transmission as an example, when the terminal has uplink data to send, it can first send it to the satellite through the service link (step A in the figure), and the satellite stores the relevant data. When the satellite moves to a position where the feeder link is available, it forwards the stored data to the terrestrial network (step B in the figure). Similarly, when there is downlink data to be sent to the terminal, the terrestrial network first sends the data to the satellite, and the satellite stores the relevant downlink data. When the satellite moves to a position where the service link is available, it forwards the stored data to the terminal.

[0051] It can be seen that in the future, it may be possible to support various types of NTN communication systems, such as NTN communication systems based on transparent payloads, NTN communication systems based on regenerative payloads, and NTN communication systems based on S&F operations. Additionally, satellites have different orbital altitudes. Different types of NTN communication systems will provide different service experiences. The terminal needs to know what type of NTN communication system it is accessing, and the network device also needs to know what type of NTN communication system the terminal is accessing. That is to say, the terminal and the network device need to know what type of cell the terminal is accessing.

[0052] However, in the related art, the terminal and the base station do not know how to obtain the cell type, which results in the terminal being unable to support more cell types.

[0053] In view of this, the embodiments of the present application provide an information acquisition method, an information acquisition device, and a communication device to solve the problem that the terminal in the related art cannot support more cell types because it does not know how to obtain the cell type.

[0054] The following will combine the accompanying drawings and, through some embodiments and their application scenarios, elaborate in detail on the information acquisition method provided by the embodiments of the present application.

[0055] Figure 5 shows a flowchart of an information acquisition method provided by an embodiment of the present application. As Figure 5 shown, the information acquisition method includes the following steps:

[0056] Step 501: The terminal receives first information from the base station;

[0057] Step 502: The terminal obtains target information based on the first information, where the target information is used to indicate the cell type.

[0058] Wherein, the target information includes information for indicating the satellite communication type, or the target information includes information for indicating the satellite orbit type and information for indicating the satellite communication type, or the target information includes information for indicating the satellite orbit type and the satellite communication type.

[0059] In the embodiments of the present application, the target information can be understood or replaced with cell type information (or cell type indication information). When the terminal obtains the target information, it can be understood that the terminal obtains the cell type information.

[0060] The cell type information obtained by the terminal may include the cell type information of the serving cell or the cell type information of the neighboring cell. The embodiments of the present application do not limit this.

[0061] The target information includes information for indicating the satellite communication type, which can be understood as that the target information does not include information for indicating the satellite orbit type. In this case, the target information indicates the satellite communication type but does not indicate the satellite orbit type.

[0062] The target information includes information for indicating the satellite orbit type and information for indicating the satellite communication type, which can be understood as that the target information includes both information for indicating the satellite orbit type and information for indicating the satellite communication type. In this case, the target information indicates both the satellite communication type and the satellite orbit type, and two pieces of information are used to respectively indicate the satellite orbit type and the satellite communication type.

[0063] The target information includes information for indicating the satellite orbit type and the satellite communication type, which can be understood as that the target information indicates both the satellite communication type and the satellite orbit type, and the same piece of information is used to indicate the satellite orbit type and the satellite communication type.

[0064] In the embodiments of the present application, the terminal receives first information from the base station; the terminal obtains target information based on the first information, where the target information is used to indicate the cell type; wherein, the target information includes information for indicating the satellite communication type, or the target information includes information for indicating the satellite orbit type and information for indicating the satellite communication type, or the target information includes information for indicating the satellite orbit type and the satellite communication type. In this way, by receiving the first information, the terminal can learn about the cell type, which enables the terminal to support more cell types, and thus enables the terminal to obtain more service experiences.

[0065] The satellite orbit type can include, for example, any one of a high orbit type, a medium orbit type, and a low orbit type. The high orbit type can be represented by GEO, i.e., Geostationary Earth Orbit. The medium orbit type can be represented by MEO, i.e., Medium Earth Orbit. The low orbit type can be represented by LEO.

[0066] The satellite communication type can include, for example, any one of a transparent payload type, a regenerative payload type, and an S&F type. The satellite communication type can be understood or replaced with the NTN communication system type, or the NTN network type.

[0067] Optionally, the target information is used to indicate the cell type, including at least one of the following:

[0068] The target information is used to indicate that the cell type is a transparent payload type;

[0069] The target information is used to indicate that the cell type is a regenerative payload type;

[0070] The target information is used to indicate that the cell type is an S&F type;

[0071] The target information is used to indicate that the cell type is a high orbit transparent payload type;

[0072] The target information is used to indicate that the cell type is a medium orbit transparent payload type;

[0073] The target information is used to indicate that the cell type is a low orbit transparent payload type;

[0074] The target information is used to indicate that the cell type is a high orbit regenerative payload type;

[0075] The target information is used to indicate that the cell type is a medium orbit regenerative payload type;

[0076] The target information is used to indicate that the cell type is a low orbit regenerative payload type;

[0077] The target information is used to indicate that the cell type is a high orbit S&F type;

[0078] The target information is used to indicate that the cell type is a medium orbit S&F type;

[0079] The target information is used to indicate that the cell type is a low orbit S&F type.

[0080] Exemplarily, the cell type information includes one or more of the following:

[0081] Transparent payload type indication information, such as transparent payload indication, can be understood as being used to indicate that the corresponding cell is a satellite-covered cell based on transparent payload; for example, a one-bit indication information. When the base station provides this one-bit indication information, the terminal learns that the cell is a satellite-covered cell based on transparent payload.

[0082] Regenerative payload type indication information, such as regenerative payload indication, can be understood as being used to indicate that the corresponding cell is a satellite-covered cell based on regenerative payload; for example, a one-bit indication information. When the base station provides this one-bit indication information, the terminal learns that the cell is a satellite-covered cell based on regenerative payload.

[0083] S&F type indication information, such as S&F indication, can be understood as being used to indicate that the corresponding cell is a satellite-covered cell with S&F capability; for example, a one-bit indication information. When the base station provides this one-bit indication information, the terminal learns that the cell is a satellite-covered cell with S&F capability.

[0084] GEO transparent payload type indication information, such as GEO transparent payload indication, can be understood as being used to indicate that the corresponding cell is a satellite-covered cell based on GEO transparent payload; for example, a one-bit indication information. When the base station provides this one-bit indication information, the terminal learns that the cell is a satellite-covered cell based on GEO transparent payload.

[0085] MEO transparent payload type indication information, such as MEO transparent payload indication, can be understood as being used to indicate that the corresponding cell is a satellite-covered cell based on MEO transparent payload; for example, a one-bit indication information. When the base station provides this one-bit indication information, the terminal learns that the cell is a satellite-covered cell based on MEO transparent payload.

[0086] LEO transparent payload type indication information, such as LEO transparent payload indication, can be understood as being used to indicate that the corresponding cell is a satellite-covered cell based on LEO transparent payload; for example, a one-bit indication information. When the base station provides this one-bit indication information, the terminal learns that the cell is a satellite-covered cell based on LEO transparent payload.

[0087] High-orbit regenerative payload type indication information, such as GEO regenerative payload indication, can be understood as information used to indicate that the corresponding cell is a cell covered by a satellite with a high-orbit regenerative payload. For example, for a one-bit indication information, when the base station provides this one-bit indication information, the terminal can learn that the cell is a cell covered by a satellite with a high-orbit regenerative payload.

[0088] Medium-orbit regenerative payload type indication information, such as MEO regenerative payload indication, can be understood as information used to indicate that the corresponding cell is a cell covered by a satellite with a medium-orbit regenerative payload. For example, for a one-bit indication information, when the base station provides this one-bit indication information, the terminal can learn that the cell is a cell covered by a satellite with a medium-orbit regenerative payload.

[0089] Low-orbit regenerative payload type indication information, such as LEO regenerative payload indication, can be understood as information used to indicate that the corresponding cell is a cell covered by a satellite with a low-orbit regenerative payload. For example, for a one-bit indication information, when the base station provides this one-bit indication information, the terminal can learn that the cell is a cell covered by a satellite with a low-orbit regenerative payload.

[0090] High-orbit S&F type indication information, such as GEO S&F indication, can be understood as information used to indicate that the corresponding cell is a cell covered by a satellite with high-orbit S&F capabilities. For example, for a one-bit indication information, when the base station provides this one-bit indication information, the terminal can learn that the cell is a cell covered by a satellite with high-orbit S&F capabilities.

[0091] Medium-orbit S&F type indication information, such as MEO S&F indication, can be understood as information used to indicate that the corresponding cell is a cell covered by a satellite with medium-orbit S&F capabilities. For example, for a one-bit indication information, when the base station provides this one-bit indication information, the terminal can learn that the cell is a cell covered by a satellite with medium-orbit S&F capabilities.

[0092] Low-orbit S&F type indication information, such as LEO S&F indication, can be understood as information used to indicate that the corresponding cell is a cell covered by a satellite with low-orbit S&F capabilities. For example, for a one-bit indication information, when the base station provides this one-bit indication information, the terminal can learn that the cell is a cell covered by a satellite with low-orbit S&F capabilities.

[0093] In some embodiments, the method further includes:

[0094] In the case where the target information does not indicate the satellite orbit type, the terminal obtains information on the satellite orbit type corresponding to the cell based on the satellite ephemeris information corresponding to the cell.

[0095] Exemplarily, in the case where the target information does not explicitly indicate the satellite orbit type, the terminal can implicitly determine the orbit type of the satellite based on the satellite ephemeris information corresponding to the cell.

[0096] In some embodiments, the first information is carried by a system message.

[0097] That is to say, the base station sends a system message to the terminal, and this system message can be understood as the system message of the serving cell. The first information is carried in the system message. In this way, after receiving the system message, the terminal can obtain the first information from the system message and, based on the first information, obtain the cell type information (i.e., the target information).

[0098] This system message can be an existing system message block in the related art or a newly introduced system message block.

[0099] The first information and the target information can be the same information, that is, the first information is the target information. Or, the first information and the target information are different information, that is, the first information contains the target information.

[0100] The ways for the terminal to obtain the cell type information can be one or more of the following:

[0101] The terminal obtains the cell type information of the serving cell from the system message of the serving cell. Exemplarily, when the terminal camps on the first cell, the terminal directly obtains the cell type information of the first cell from the system message of the first cell.

[0102] The terminal obtains the cell type information of neighboring cells from the system message of the serving cell. Exemplarily, when the terminal camps on the first cell, the terminal obtains the cell type information of the neighboring cells provided by the first cell from the system message of the first cell.

[0103] Optionally, the system message is at least one of System Information Block 1 (SIB1), NTN-related system message, and cell reselection-related system message.

[0104] Among them, the NTN-related system message can be understood as the NTN dedicated system message. For example, it includes SIB31 in the LTE scenario or SIB19 in the NR scenario. That is to say, the cell type information can be carried by SIB31 or SIB19.

[0105] System information related to cell reselection includes, for example, at least one of SIB4 and SIB5. That is, cell type information can be carried by at least one of SIB4 and SIB5.

[0106] Optionally, the SIB1 includes a first Information Element (IE) for indicating cell access control information, and the first IE carries the target information.

[0107] That is, cell type information is carried by SIB1. Specifically, it is carried by the first IE in SIB1. The first IE can be a cell access control information element (such as the cellAccessRelatedInfo IE). Exemplarily, a cell type field is introduced in the cell access control information element of SIB1 of a cell, and this cell type field is used to indicate the cell type of the corresponding cell.

[0108] Optionally, the SIB31 includes a first field that contains the target information.

[0109] Exemplarily, a cell type field (i.e., the first field) is introduced in SIB31, and this cell type field is used to indicate the cell type of the corresponding cell.

[0110] Optionally, the SIB19 includes at least one of a second field and a third field;

[0111] wherein, the second field contains first target information, and the first target information is target information for indicating the cell type of the serving cell;

[0112] the third field contains second target information, and the second target information is target information for indicating the cell type of a neighboring cell.

[0113] Exemplarily, one cell type field or two cell type fields are introduced in SIB19. When one cell type field is introduced in SIB19, this cell type field is used to indicate the cell type of the serving cell or the cell type of the neighboring cell. When two cell type fields are introduced in SIB19, these two cell type fields are respectively used to indicate the cell type of the serving cell and the cell type of the neighboring cell.

[0114] Optionally, the SIB4 includes a second IE for indicating information of co-frequency neighboring cells;

[0115] wherein, the second IE carries third target information, and the third target information is target information for indicating the NTN type of co-frequency neighboring cells.

[0116] The second IE may be an intra-frequency neighboring cell information element (such as an IntraFreqNeighCellInfo IE). Exemplarily, cell type information is carried in the intra-frequency neighboring cell information element of SIB4 to indicate the cell type of the intra-frequency neighboring cell.

[0117] Optionally, the SIB5 includes a third IE, and the third IE is used to indicate information of an inter-frequency neighboring cell;

[0118] Wherein, the third IE carries a fourth target information, and the fourth target information is target information for indicating the cell type of the inter-frequency neighboring cell.

[0119] The second IE may be an inter-frequency neighboring cell information element (such as an InterFreqNeighCellInfo IE). Exemplarily, cell type information is carried in the inter-frequency neighboring cell information element of SIB5 to indicate the cell type of the inter-frequency neighboring cell.

[0120] The above describes various optional ways for the terminal to obtain cell type information. The following describes the behavior of the terminal after obtaining the cell type information.

[0121] In some embodiments, the method further includes:

[0122] The terminal sends a Cell Global Identity (CGI) report to the base station, and the CGI report includes information for indicating the cell type.

[0123] Exemplarily, in the case where the network configures the terminal to report CGI, if the configured cell provides cell type information, or in other words, if the terminal obtains the cell type information of the configured cell, the terminal may carry information for indicating the cell type in the CGI reporting information (such as CGI-info).

[0124] In this way, network devices (including base stations and core network devices) can obtain the cell type information of the cell accessed by the terminal from the CGI reporting information, so that the base station can know the cell type of the cell accessed by the terminal, thereby ensuring that the terminal obtains a better service experience.

[0125] In some embodiments, the method further includes:

[0126] When the terminal initiates a target service, it selects a target cell based on the cell type information of at least one cell.

[0127] That is to say, when the terminal initiates a target service, the terminal can select a suitable cell based on the cell type information. Exemplarily, it can be to select a cell suitable for the target service data transmission. This can ensure that the terminal obtains a better service experience.

[0128] Optionally, when the target service is a delay-tolerant service, the cell type of the target cell includes the S&F type.

[0129] Optionally, when the target service supports transmission by the store-and-forward method, the cell type of the target cell includes the S&F type.

[0130] It should be noted that the above actions of the terminal after obtaining the cell type information can enable the terminal to support more cell types, thereby enabling the terminal to obtain more service experiences.

For example, base station IDs 1 to 6 correspond to base stations of the regenerative load type, and base station IDs 7 to 14 correspond to base station types of the S&F type. The specific configuration rules can be configured by Operations, Administration and Maintenance (OAM) for the base station.

[0179] For the manner of obtaining the base station type information from a base station, exemplarily, in the base station interface establishment process (such as X2 / Xn setup procedure), base station 1 provides the base station type information of base station 1 to base station 2, and base station 2 provides the base station type information of base station 2 to base station 1. Base station 1 can obtain the cell type information of the cells managed by base station 2 based on the base station type information of base station 2, and base station 2 can also obtain the cell type information of the cells managed by base station 1 based on the base station type information of base station 1;
