[0046] Before describing the embodiments of the present application, the following briefly introduces the relevant technologies:

[0047] 1. NTN Communication System

[0048] Figure 2 shows a typical deployment scenario for an NTN communication system (also known as a satellite communication system). As shown in Figure 2, user equipment (UE), base stations, and core network equipment are all deployed on the ground, and communication data between the terminal and network equipment is relayed via satellites in the air. The link between the terminal and the satellite is called a service link, and the link between the satellite and the ground gateway is called a feeder link. In certain scenarios, such as low-Earth orbit (LEO) satellites (abbreviated as LEO satellites or LEO satellites), service link or feeder link switching may occur due to satellite movement. For service link switching, the service satellite for all UEs 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.

[0049] Currently proposed NTN communication systems include two types: one based on transparent payloads and one based on regenerative payloads. In the 3rd Generation Partnership Project (3GPP) Releases 17 (R17) and 18 (R18), only transparent payload-based NTN systems are considered. In transparent payload-based NTN systems, satellites only forward data between base stations and terminals and do not decode or process this data. In regenerative payload-based NTN systems, satellites possess some or all base station functions and can decode and process uplink or downlink data. For example, if a satellite possesses all access network functions, the access network equipment can be referred to as on-board access network equipment or on-board base station equipment. In layman's terms, this can also be referred to as a base station on-board satellite. In this case, the access network's Centralized Unit (CU) functions are referred to as the on-board access network's CU, and the access network's Distributed Unit (DU) functions are referred to as the on-board access network's DU. If a satellite has the CU function of an access network, the CU of the access network can be called the onboard CU of the access network equipment. In layman's terms, this can also be called CU-on-satellite. If a satellite has the DU function of an access network, the DU of the access network can be called the onboard DU of the access network equipment. In layman's terms, this can also be called DU-on-satellite.

[0050] 2. Store and forward (S&F) communication mode

[0051] In the NTN communication system, in order to realize data or signaling interaction between the terminal and the ground network, it is necessary to ensure that the service link and the feeder link remain connected at the same time, as shown in Figure 3.

[0052] However, in some cases, such as the initial stage of satellite network deployment, it cannot be guaranteed that the service link and the feeder link can remain connected at the same time. To support data transmission (such as delay-tolerant service data), a store-and-forward communication mode is proposed, as shown in Figure 4. Taking 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 (as shown in step A in the figure), and the satellite stores the relevant data. When the satellite operates to the point where the feeder link is available, the stored data is forwarded to the ground network (step B in the figure). Similarly, when downlink data needs to be sent to the terminal, the ground network first sends the data to the satellite, and the satellite stores the relevant downlink data. When the satellite operates to the point where the service link is available, the stored data is forwarded to the terminal.

[0053] It can be seen that in the future, multiple types of NTN communication systems may be supported, including those based on transparent load, those based on regenerative load, and those based on S&F operations. Furthermore, satellites have different orbital altitudes. Different types of NTN communication systems will provide different service experiences. Terminals need to know which type of NTN communication system they are accessing, and network equipment also needs to know which type of NTN communication system they are accessing. In other words, both the terminal and the network equipment need to know the type of cell the terminal is accessing.

[0054] However, in related technologies, 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.

[0055] 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 in the related art that the terminal does not know how to obtain the cell type and thus cannot support more cell types.

[0056] The information acquisition method provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0057] FIG5 is a flowchart of an information acquisition method provided by an embodiment of the present application. As shown in FIG5 , the information acquisition method includes the following steps:

[0058] Step 501: The terminal receives first information from a base station;

[0059] Step 502: The terminal obtains target information based on the first information, where the target information is used to indicate a cell type.

[0060] The target information includes information for indicating a satellite communication type, or the target information includes information for indicating a satellite orbit type and information for indicating a satellite communication type, or the target information includes information for indicating a satellite orbit type and a satellite communication type.

[0061] In the embodiment of the present application, the target information can be understood or replaced by cell type information (or cell type indication information). The terminal acquiring the target information can be understood as the terminal acquiring the cell type information.

[0062] The cell type information acquired by the terminal may include the cell type information of the serving cell, and may also include the cell type information of the neighboring cell, which is not limited in this embodiment of the present application.

[0063] The target information includes information for indicating the satellite communication type. It can be understood 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.

[0064] The target information includes information for indicating the satellite orbit type and information for indicating the satellite communication type. It can be understood 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 indicate the satellite orbit type and the satellite communication type respectively.

[0065] The target information includes information for indicating the satellite orbit type and the satellite communication type. It can be understood that the target information indicates both the satellite communication type and the satellite orbit type, and the same information is used to indicate the satellite orbit type and the satellite communication type.

[0066] In an embodiment of the present application, a terminal receives first information from a base station; based on the first information, the terminal obtains target information, where the target information is used to indicate a cell type; wherein the target information includes information indicating a satellite communication type, or includes information indicating a satellite orbit type and information indicating a satellite communication type, or includes information indicating a satellite orbit type and a satellite communication type. In this way, by receiving the first information, the terminal can obtain the cell type, which enables the terminal to support more cell types and thus provide a wider service experience.

[0067] Satellite orbit types can include, for example, high orbit, medium orbit, and low orbit. A high orbit can be represented by GEO, or Geostationary Earth Orbit. A medium orbit can be represented by MEO, or Medium Earth Orbit. A low orbit can be represented by LEO.

[0068] The satellite communication type may include, for example, any one of a transparent load type, a regenerative load type, and an S&F type. The satellite communication type may be understood or replaced by an NTN communication system type or an NTN network type.

[0069] Optionally, the target information is used to indicate a cell type, including at least one of the following:

[0070] The target information is used to indicate that the cell type is a transparent load type;

[0076] The target information is used to indicate that the cell type is a high orbit regeneration load type;

[0077] The target information is used to indicate that the cell type is a medium track regeneration load type;

[0078] The target information is used to indicate that the cell type is a low orbit regeneration load type;

[0080] The target information is used to indicate that the cell type is a medium track S&F type;

[0081] The target information is used to indicate that the cell type is a low-orbit S&F type.

[0082] Exemplarily, the cell type information includes one or more of the following:

[0083] Transparent payload type indication information, such as transparent payload indication, can be understood as being used to indicate that a corresponding cell is a cell covered by a satellite based on a transparent payload; for example, one-bit indication information, when a base station provides the one-bit indication information, the terminal learns that the cell is a cell covered by a satellite based on a transparent payload;

[0084] Regenerative load type indication information, such as regenerative payload indication, can be understood as being used to indicate that a corresponding cell is a cell covered by a satellite based on a regenerative load; for example, one-bit indication information, when a base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite based on a regenerative load;

[0085] S&F type indication information, such as S&F indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite with S&F capabilities; for example, one-bit indication information. When the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite with S&F capabilities.

[0086] High-orbit 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 cell covered by a satellite based on a high-orbit transparent payload; for example, one-bit indication information, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite based on a high-orbit transparent payload;

[0087] Medium orbit 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 cell covered by a satellite based on a medium orbit transparent payload; for example, one-bit indication information, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite based on a medium orbit transparent payload;

[0088] Low-orbit 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 cell covered by a satellite based on a low-orbit transparent payload; for example, one-bit indication information, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite based on a low-orbit transparent payload;

[0089] High-orbit regenerative payload type indication information, such as GEO regenerative payload indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite based on a high-orbit regenerative payload; for example, one-bit indication information, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite based on a high-orbit regenerative payload;

[0090] Medium orbit regenerative payload type indication information, such as MEO regenerative payload indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite based on a medium orbit regenerative load; for example, one-bit indication information, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite based on a medium orbit regenerative load;

[0091] Low-orbit regenerative payload type indication information, such as LEO regenerative payload indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite based on a low-orbit regenerative payload; for example, one-bit indication information, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite based on a low-orbit regenerative payload;

[0092] High-orbit S&F type indication information, such as GEO S&F indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite with high-orbit S&F capabilities. For example, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite with high-orbit S&F capabilities.

[0093] Medium Earth Orbit S&F type indication information, such as MEO S&F indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite with medium earth orbit S&F capability; for example, one-bit indication information, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite with medium earth orbit S&F capability;

[0094] Low-orbit S&F type indication information, such as LEO S&F indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite with low-orbit S&F capabilities; for example, one-bit indication information, when the base station provides the one-bit indication information, the terminal knows that the cell is a cell covered by a satellite with low-orbit S&F capabilities.

[0095] In some embodiments, the method further comprises:

[0096] In a case where the target information does not indicate a satellite orbit type, the terminal acquires information on a satellite orbit type corresponding to the cell based on satellite ephemeris information corresponding to the cell.

[0097] Exemplarily, when the target information does not explicitly indicate the satellite orbit type, the terminal can implicitly determine the satellite orbit type based on the satellite ephemeris information corresponding to the cell.

[0098] In some embodiments, the first information is carried via a system message.

[0099] That is, the base station sends a system message to the terminal, which can be understood as a system message of the serving cell. The system message carries the first information, so that after receiving the system message, the terminal can obtain the first information from the system message and obtain the cell type information (i.e., target information) based on the first information.

[0100] The system message may be an existing system message block in the related art, or a newly introduced system message block.

[0101] The first information and the target information may be the same information, that is, the first information is the target information, or the first information and the target information may be different information, that is, the first information includes the target information.

[0102] The terminal may obtain cell type information in one or more of the following ways:

[0103] The terminal obtains the cell type information of the serving cell from the system message of the serving cell. Exemplarily, when the terminal is camped in the first cell, the terminal directly obtains the cell type information of the first cell from the system message of the first cell.

[0104] The terminal obtains the cell type information of the neighboring cell through the system message of the serving cell. Exemplarily, when the terminal is camped in the first cell, the terminal obtains the cell type information of the neighboring cell provided by the first cell from the system message of the first cell.

[0105] Optionally, the system message is at least one of a system information block 1 (System Information Block 1, SIB1), an NTN-related system message, and a cell reselection-related system message.

[0106] Among them, NTN-related system messages can be understood as NTN-specific system messages, such as SIB31 in the LTE scenario or SIB19 in the NR scenario. In other words, cell type information can be carried by SIB31 or SIB19.

[0107] The system message related to cell reselection includes, for example, at least one item of SIB4 and SIB5. That is, the cell type information may be carried by at least one item of SIB4 and SIB5.

[0108] Optionally, the SIB1 includes a first information element (IE), where the first IE is used to indicate cell access control information, and the first IE carries the target information.

[0109] That is, the cell type information is carried by SIB1, specifically, by the first IE in SIB1. The first IE may be a cell access control information element (e.g., cellAccessRelatedInfo IE). Exemplarily, a cell type field is introduced in the cell access control information element of SIB1 of the cell, and the cell type field is used to indicate the cell type of the corresponding cell.

[0110] Optionally, the SIB31 includes a first field, and the first field contains the target information.

[0111] Exemplarily, a cell type field (ie, the first field) is introduced in SIB31, and the cell type field is used to indicate the cell type of the corresponding cell.

[0112] Optionally, the SIB19 includes at least one of the second field and the third field;

[0113] The second domain includes first target information, where the first target information is target information for indicating a cell type of a serving cell;

[0114] The third field contains second target information, where the second target information is target information used to indicate a cell type of a neighboring cell.

[0115] Exemplarily, one cell type field or two cell type fields are introduced in SIB19. When one cell type field is introduced in SIB19, the cell type field is used to indicate the cell type of the serving cell, or to indicate the cell type of the neighboring cell. When two cell type fields are introduced in SIB19, the two cell type fields are used to indicate the cell type of the serving cell and the cell type of the neighboring cell, respectively.

[0116] Optionally, the SIB4 includes a second IE, where the second IE is used to indicate information of a same-frequency neighboring cell;

[0117] The second IE carries third target information, and the third target information is target information for indicating the NTN type of the same-frequency neighboring cell.

[0118] The second IE may be an intra-frequency neighbor cell information element (eg, IntraFreqNeighCellInfo IE). Exemplarily, the intra-frequency neighbor cell information element of SIB4 carries cell type information, which is used to indicate the cell type of the intra-frequency neighbor cell.

[0119] Optionally, the SIB5 includes a third IE, where the third IE is used to indicate information of an inter-frequency neighboring cell;

[0120] The third IE carries fourth target information, and the fourth target information is target information for indicating the cell type of the hetero-frequency neighboring cell.

[0121] The second IE may be an inter-frequency neighbor cell information element (such as InterFreqNeighCellInfo IE). Exemplarily, the inter-frequency neighbor cell information element of SIB5 carries cell type information, which is used to indicate the cell type of the inter-frequency neighbor cell.

[0122] The above describes various optional ways for a terminal to obtain cell type information. The following describes the behavior of the terminal after obtaining the cell type information.

[0123] In some embodiments, the method further comprises:

[0124] The terminal sends a Cell Global Identity (CGI) report to the base station, where the CGI report includes information indicating a cell type.

[0125] For example, when the network configures the terminal to report CGI, if the configured cell provides cell type information, or if the terminal obtains the cell type information of the configured cell, the terminal can carry information indicating the cell type in the CGI reporting information (such as CGI-info).

[0126] In this way, network equipment (including base stations and core network equipment) 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.

[0127] In some embodiments, the method further comprises:

[0128] When initiating a target service, the terminal selects a target cell based on cell type information of at least one cell.

[0129] That is, when the terminal initiates a target service, it can select an appropriate cell based on the cell type information. For example, it can select a cell suitable for data transmission of the target service. This ensures that the terminal obtains a better service experience.

[0130] Optionally, when the target service is a delay-tolerant service, the cell type of the target cell includes an S&F type.

[0131] Optionally, when the target service supports transmission in a store-and-forward manner, the cell type of the target cell includes an S&F type.

[0132] It should be noted that the above-mentioned behavior 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.

[0133] The embodiments of the present application are applicable to LTE and NR communication systems, as well as subsequent evolved communication systems.

[0134] The above is an embodiment of the method on the terminal side. The following describes an embodiment of the method on the base station side.

[0163] Low-orbit regenerative payload type indication information, such as LEO regenerative payload indication, may be understood as being used to indicate that a corresponding cell is a cell covered by a satellite based on a low-orbit regenerative payload, or being used to indicate that a corresponding base station is a base station on a satellite based on a low-orbit regenerative payload;

[0164] High-orbit S&F type indication information, such as GEO S&F indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite with high-orbit S&F capabilities, or being used to indicate that the corresponding base station is a base station on a satellite with high-orbit S&F capabilities;

[0166] Low-orbit S&F type indication information, such as LEO S&F indication, can be understood as being used to indicate that the corresponding cell is a cell covered by a satellite with low-orbit S&F capabilities, or being used to indicate that the corresponding base station is a base station on a satellite with low-orbit S&F capabilities.

[0167] Optionally, the method further includes:

[0168] When the target information does not indicate the satellite orbit type, the first base station obtains information on the satellite orbit type corresponding to the cell or the satellite orbit type corresponding to the base station based on the satellite ephemeris information corresponding to the cell or the satellite ephemeris information corresponding to the base station.

[0169] Optionally, the first base station acquires target information, including at least one of the following:

[0170] The first base station acquires the target information based on identification information of the base station, where there is a mapping relationship between the identification information and the base station type;

[0171] The first base station obtains the target information during a base station interface establishment process;

[0172] The first base station obtains the target information during an operation and maintenance (O&M) process;

[0173] The first base station obtains the target information based on a CGI report (ie, CGI reporting information) from the terminal, where the CGI report includes information indicating a cell type.

[0174] For the above-mentioned method of obtaining target information based on the identification information of the base station, exemplarily, a mapping relationship (or association relationship, correspondence relationship) between the identification information and the base station type can be configured, and a specific base station identifier (ID) corresponds to a specific base station type. For example, base station ID1 to ID6 correspond to base stations of the regeneration load type, and base station ID7 to ID14 correspond to base station types of the S&F type. Specific configuration rules can be configured to the base station by operations, administration and maintenance (OAM). Additionally, based on the identification information of the base station, the cell type information corresponding to the cell managed by the base station corresponding to the identification information of the base station can be obtained.

[0175] The aforementioned method of obtaining target information during the O&M process can be understood as providing the target information to the first base station via O&M. For example, the operator can provide base station or cell type information via O&M. In layman's terms, O&M provides or pre-configures NTN load-related information, such as ephemeris information, orbital parameter information, satellite load type information, or satellite capability information.

[0176] Regarding the above-mentioned method of obtaining target information based on CGI reporting information, illustratively, the terminal also carries cell type information in the CGI reporting information (such as CGI-info), so that the base station can obtain the cell type information based on the CGI reporting information. It should be noted that the CGI report can be a neighboring cell CGI report.

[0177] Optionally, the first base station acquires the target information during the base station interface establishment process, including at least one of the following:

[0178] During a process of establishing a base station interface with a second base station, the first base station receives second information from the second base station, and acquires the target information based on the second information, wherein the second information includes information indicating a cell type of a cell managed by the second base station or a base station type of the second base station;

[0179] During the process of establishing a base station interface with a third base station, the first base station sends third information to the third base station and obtains the target information based on the third information, wherein the third information includes information for indicating the cell type of the cell managed by the first base station or the base station type of the first base station.

[0180] Acquiring target information during the process of establishing a base station interface may include two methods: acquiring base station type information from the base station and acquiring cell type information from the base station.

[0181] Regarding the method of obtaining the base station type information from the base station, illustratively, during the base station interface establishment procedure (such as the X2 / Xn setup procedure), base station 1 provides base station 2 with its base station type information, and base station 2 provides base station 1 with its base station type information. Base station 1 can obtain the cell type information of the cell 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 cell managed by base station 1 based on the base station type information of base station 1.

[0182] Regarding the method of obtaining cell type information from the base station, exemplarily, in the base station interface establishment process (such as X2 / Xn setup procedure), base station 1 provides base station 2 with the cell type information of the service cell of base station 1, and base station 2 provides base station 1 with the cell type information of the service cell of base station 2.

[0195] A medium orbit regenerative payload access type, such as a MEO regenerative payload access type, can be understood as indicating that the terminal accesses a cell covered by a satellite based on a medium orbit regenerative payload. For example, one bit of indication information is used for indication.

[0209] In some embodiments, the method further comprises:

[0210] In the case where the second terminal needs to switch from the first base station to the fourth base station, the first base station sets a switching negotiation timer based on the cell type of the cell managed by the first base station or the base station type of the first base station, and the cell type of the cell managed by the fourth base station or the base station type of the fourth base station.

[0211] That is, during a terminal handover (HO) process, the base station may start a handover negotiation timer that matches the base station type (or cell type) based on the base station type information (or cell type information). The handover process may include X2 / Xn-based HO and S1 / NG-based HO.

[0212] For example, assuming that the source base station is a high-orbit regenerative load type base station and the target base station is a ground base station, during the handover process, the source base station may set a handover negotiation timer based on the round trip time (RTT) between the source base station and the target base station. As another example, assuming that both the source base station and the target base station are high-orbit regenerative load type base stations, during the handover process, the source base station may set a handover negotiation timer based on the RTT of the inter-satellite link between the source base station and the target base station.

[0213] In some embodiments, the method further comprises:
