[0121] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0122] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein, for example, are implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0124] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0125] The relevant concepts mentioned in this application are briefly described below.

[0126] 1. Non-Terrestrial Network (NTN, i.e. satellite network)

[0127] NTN refers to using satellites as communication relays to connect terminals and base stations wirelessly. NTN can improve network coverage and provide continuous coverage for terminals in scenarios such as deserts and oceans.

[0128] A typical NTN is as follows: the service link is between the NTN satellite and the terminal, and the feeder link is between the NTN satellite and the NTN gateway. For ease of understanding, the NTN satellite and the NTN gateway are usually considered as part of the gNB.

[0129] Based on this network architecture, NTN satellites transparently forward data from base stations to terminals. Similarly, terminal data is transparently forwarded to NTN gateways and base stations via NTN satellites.

[0130] The NTN network includes the following three service links:

[0131] Earth-fixed cell: The cell covered by NTN satellites remains unchanged, such as the cell projected on the ground by Geosynchronous Earth Orbit (GEO) satellites.

[0132] Quasi-Earth-fixed cell: The satellite beam stably covers a fixed area on the surface for a period of time.

[0133] Earth-moving cell (EMC): In this scenario, the satellite's beam coverage slides on the surface of the earth.

[0134] In a quasi-earth fixed cell (EFC), the coverage of the satellite remains unchanged over a period of time. The concept of reference location is defined in EFC to assist the user equipment (UE) in determining the distance to the cell. One possible implementation method is that the reference location is the center of a circular cell. Since the coverage of the satellite remains unchanged over a period of time in EFC, the reference location will not change during this service time. In conditional handover (CHO), the terminal determines whether it is far away from the source cell and / or whether it is close to the target cell by comparing the distance with the reference location. When the conditions are met, the terminal switches to the target cell.

[0135] In EMC, the coverage area of ​​the satellite changes as the satellite moves.

[0136] 2. Store and forward (S&F) mode

[0137] In 5G networks, S&F refers to satellite access providing such a communication service: for services with low latency requirements, the satellite provides intermittent / temporary satellite connections within the satellite coverage area (for example, the satellite is not connected to the ground network through a feeder link or inter-satellite link).

[0138] Here is an example from S&F:

[0139] In the normal / default satellite operation mode, the interaction of signaling and data requires the simultaneous activation of the service link and feeder link on the terminal and remote ground network sides. In this way, when the terminal communicates with the satellite via the service link, there will be a continuous end-to-end (from the terminal to the satellite, and the ground network) connection path.

[0140] In contrast, in the S&F satellite mode, the end-to-end signaling / data service consists of two steps. In step A, signaling and data transmission are performed between the terminal and the satellite, but the satellite is not served by the ground network side (i.e., the satellite can provide a service link, but there is no activated feeder link). In step B, the connection between the satellite and the ground network is established, so the communication between the satellite and the ground network side begins. Therefore, the satellite is connected to the terminal in step A and then connected to the ground network in step B.

[0141] The sub-satellite point can be considered as the projection of the satellite on the ground;

[0142] Reference location: It indicates the projection of the center point of the cell served by the satellite on the ground, which has a relative position relationship with the sub-satellite point.

[0143] Through analysis, it is found that at time T1, when the satellite and the terminal complete data transmission, the satellite cannot connect to the core network, that is, there is no feeder link, so the satellite has no DL data transmission. Therefore, at this time, if the terminal still receives Paging or PDCCH or broadcast messages, it will cause a waste of power consumption of the terminal.

[0144] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1As shown, it includes a user terminal 11 and a base station 12, wherein the user terminal 11 may be a user equipment (User Equipment, UE), for example: it may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device). It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present application. The above-mentioned base station 12 may be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0145] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The information transmission method, device, terminal and network device provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0146] The embodiments of the present application provide an information transmission method, apparatus, terminal and network device to solve the problem of terminal power consumption waste in the S&F scenario.

[0147] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0148] like Figure 2 As shown, an embodiment of the present application provides an information transmission method, which is executed by a terminal and includes:

[0149] Step S201, receiving a first message sent by an onboard network device, wherein the first message carries target time information;

[0150] The first message is used to instruct the terminal to stop receiving indication information within the time range indicated by the target time information, and the indication information includes at least one of the following: a paging message, a physical downlink control channel PDCCH, and a broadcast message.

[0151] Optionally, another way of understanding may be: the first message is used to instruct the terminal to start receiving indication information after the time range indicated by the target time information; that is, the terminal does not receive indication information within the time range indicated by the onboard network device. As long as it exceeds this time range (that is, as long as it is not within this time range), the terminal starts to monitor paging messages, PDCCH and / or receive broadcast messages according to the Paging cycle; this method can avoid the terminal having to continue to receive paging messages, PDCCH and / or broadcast messages when there is no data transmission, resulting in waste of terminal power consumption.

[0152] It should be noted here that for the reception of paging messages, the main process includes: the terminal monitors the PDCCH of the scheduled paging message, decodes the PDCCH encrypted by the paging radio network temporary identifier (Paging Radio Network Temporary Identifier, P-RNTI), and then receives the paging message based on the decoding result; in order to reduce the power consumption of the terminal during the reception of the paging message, optionally, in an embodiment of the present application, the reception of the PDCCH of the scheduled paging message is stopped within the time range indicated by the target time information.

[0153] For the reception of broadcast messages, the main process includes: the terminal determines the period, window and other information of the broadcast message, and listens to the PDCCH encrypted by the System Information Radio Network Temporary Identifier (SI-RNTI) in the corresponding period and window, and parses the Physical downlink shared channel (PDSCH) indicated by the PDCCH, and continues to parse the broadcast message indicated by the PDSCH content according to the PDSCH content; in order to reduce the power consumption of the terminal during the reception of the broadcast message, optionally, in an embodiment of the present application, the PDCCH for scheduling the broadcast message is stopped within the time range indicated by the target time information.

[0154] Optionally, the first message may be a radio resource control (RRC) release message or a broadcast message. Of course, the first message may also be other messages except the RRC release message and the broadcast message; further optionally, in the case where the first message is an RRC release message, the method further includes:

[0155] According to the first message, enter the RRC idle (RRC_IDLE) state or the RRC inactive (RRC_INACTIVE) state.

[0156] That is to say, in this case, the first message is also used to instruct the terminal to enter an idle state or an inactive state. After the terminal receives the RRC release message, the terminal needs to enter the RRC idle state or the RRC inactive state, and stop receiving the indication information in the RRC idle state or the RRC inactive state within the time range indicated by the target time information.

[0157] Optionally, the RRC release message is a non-secure encrypted message.

[0158] Optionally, in an implementation manner, before entering the RRC idle state or the RRC inactive state according to the first message, the method further includes:

[0159] Under target conditions, determining not to decrypt or verify the integrity of the first message;

[0160] The target condition includes at least one of the following:

[0161] A1. receiving notification information sent by an onboard network device, where the notification information is used to indicate that the onboard network device cannot provide a feeder link;

[0162] This situation can be understood as that when the onboard network equipment is unable to provide a feeding link for the terminal, it can send a notification message to the terminal. When the terminal receives the notification message, if it also receives an RRC release message, the terminal may not decrypt or integrity verify the non-securely encrypted first message, but directly enter the RRC idle state or RRC inactive state.

[0163] A2. The current transmission data state indicates that the terminal can enter the RRC idle state or the RRC inactive state according to the first message;

[0164] For example, the transmission data state is before the terminal receives the registration acceptance message. Optionally, if the terminal does not receive the registration acceptance message (that is, before receiving the registration acceptance message), the terminal determines that it can enter the RRC idle state or the RRC inactive state according to the non-securely encrypted RRC release message; optionally, if the terminal receives the registration acceptance message (that is, after receiving the registration acceptance message), the terminal determines that it cannot enter the RRC idle state or the RRC inactive state according to the non-securely encrypted RRC release message, that is, the terminal needs to decrypt or verify the integrity of the RRC release message.

[0165] Optionally, in the case where the first message is a broadcast message, the target time information is associated with the cell information or the ephemeris information. The target time information is associated with the cell information or the ephemeris information, which can be understood as: the target time information is bound to the cell information or the ephemeris information, that is, different cell information may correspond to different target time information, or different ephemeris information may correspond to different target time information; it can also be understood as: the target time information is only applicable to a specific cell or a specific ephemeris.

[0166] Typically, the satellite network device can send the association between the target time information and the cell information or ephemeris information based on the broadcast message. When the terminal is subsequently used, the corresponding target time information is used depending on which cell it accesses or the cell range corresponding to the ephemeris.

[0167] Optionally, in one implementation, the method further includes:

[0168] The cell information or the ephemeris information is determined by at least one of the following:

[0169] A11, RRC release message;

[0170] A12, RRC reconfiguration message;

[0171] A13, the cell served by the satellite selected when the terminal first accesses;

[0172] A14: The cell selected when the terminal accesses for the first time.

[0173] It should be noted that when the target time information is associated with the cell information, the cell information is usually determined by at least one of A11, A12 and A14; when the target time information is associated with the ephemeris information, the ephemeris information is usually determined by at least one of A11-A13.

[0174] For example, the cell information may refer to a specific cell. When the terminal is instructed to perform data transmission on a specific cell, the terminal will associate the specific cell with the target time information. For example, the ephemeris information may refer to a specific ephemeris, which usually includes one or more cells. When the terminal is instructed to perform data transmission on a specific ephemeris, the terminal will associate the specific ephemeris with the target time information, that is, the terminal associates one or more cells corresponding to the ephemeris with the target time information.

[0175] It should also be noted that, when the first message is a broadcast message and the indication information is also a broadcast message, the satellite network usually instructs the first broadcast message, i.e., the first message, to stop receiving the subsequently sent broadcast messages within the time range indicated by the target time information. That is, the two broadcast messages in this case are sent at different times and carry different contents.

[0176] Optionally, when the first message is a message other than an RRC release message and a broadcast message, the first message also carries a target indication, and the target indication is used to instruct the terminal to enter a target state, and the terminal stops receiving the indication information in the target state.

[0177] Optionally, the target state can be understood as a state other than the RRC idle state, the RRC inactive state, and the RRC connected state. The target state can be understood as a temporary state. In this temporary state, the terminal does not need to receive indication information.

[0178] Optionally, in one implementation, the target time information includes at least one of the following:

[0179] B11, starting time and / or preset time length;

[0180] Optionally, if only the starting time is configured in the target time information, the preset time length may be agreed upon by the protocol or preconfigured; if only the preset time length is configured in the target time information, the starting time may be agreed upon by the protocol or preconfigured.

[0181] Optionally, the start time may be the Coordinated Universal Time (UTC) time, and the preset time length may be in units of hours, minutes, seconds, etc.

[0182] B12, deadline;

[0183] In this case, it can be understood that only one deadline is configured in the target time information, that is, the terminal can receive the indication information after the deadline.

[0184] Optionally, the deadline can be UTC time.

[0185] B13. A first time list, wherein the first time list includes one or more time windows.

[0186] In this case, it can be understood that one or more time windows are configured in the target time information, and the terminal receives the indication information within these time windows, and stops receiving the indication information outside these time windows.

[0187] Optionally, in one implementation, in this case, the method further includes the following:

[0188] C11. When the target time information includes a starting time and / or a preset time length, start the target timer at the starting time, and stop receiving the indication information during the running time of the target timer, wherein the timing duration of the target timer is the preset time length;

[0189] That is, in this case, a target timer is set and started at the starting time. As long as the target timer is running, the terminal does not receive the indication information.

[0190] Optionally, in one implementation, the method further includes:

[0191] During the running time of the target timer, if the terminal enters a connected state, the target timer is stopped.

[0192] This situation can be understood as that during the running time of the target timer, the terminal is in the RRC idle state or the RRC inactive state. When the terminal has a data transmission demand, enters the RRC connected state or performs early data transmission (EDT) / small data transmission (SDT), it indicates that the terminal needs to receive the indication information, the terminal needs to stop the target timer, and set the value of the target timer to an invalid value. Optionally, the invalid value can be a negative value.

[0193] C12. When the target time information includes a deadline, stop receiving the indication information within a time range from the time when the first message is received to the deadline;

[0194] That is to say, in this case, the starting time can be set by default to the time when the first message is received. At this time, the terminal starts not to receive the indication information until the terminal determines that the current time has reached the end time, then stops not receiving the indication information, that is, the terminal starts to receive the indication information.

[0195] Optionally, in one implementation, the method further includes:

[0196] Before the deadline is reached, if the terminal enters a connected state, the deadline is set to an invalid value.

[0197] This situation can be understood as that before the deadline is reached, the terminal is in an RRC idle state or an RRC inactive state. When the terminal has a data transmission requirement, enters an RRC connected state or performs early data transmission (EDT) / small data transmission (SDT), it indicates that the terminal needs to receive the indication information, and the terminal no longer uses the deadline, that is, the deadline is set to an invalid value. Optionally, the invalid value can be a negative value.

[0198] C13. When the target time information includes a first time list, stop receiving the indication information outside one or more time windows indicated by the first time list.

[0199] That is to say, the time windows configured in the first time list are time windows for receiving indication information, and the terminal receives indication information only within these time windows, and no longer receives indication information outside the time windows.

[0200] Optionally, the onboard network device may determine the target time information through target information:

[0201] The target information includes at least one of the following:

[0202] D11, service characteristics of the terminal;

[0203] For example, the service characteristics may include, but are not limited to, the service cycle, the size of the service data volume, etc.

[0204] D12, satellite ephemeris information;

[0205] For example, the time information of the next satellite being able to provide coverage to the terminal, or the time information of the next satellite being able to provide coverage to a specific geographical location area.

[0206] Optionally, the specific geographical location area may be a geographical location range, such as a sea area, a tropical rain forest, a grassland, etc., and the shape may be irregular. The first geographical location may be described by a circle center and a radius, and the circle center may be a longitude and latitude coordinate; or it may be an irregular shape drawn by multiple points, such as a series of geographical location coordinates (such as longitude and latitude coordinates) points, and the description method of connecting these points.

[0207] D13, indication of core network equipment;

[0208] Optionally, in this case, it can be understood that the on-board network device does not need to determine the target time information by itself, but the core network device determines the target time information and directly indicates it to the on-board network device.

[0209] The specific application examples of the embodiments of the present application are described below.

[0210] Application scenario 1: After completing data transmission with the terminal, the onboard network device (also called a satellite) indicates the target time information to the terminal. The terminal stops receiving Paging messages and / or PDCCH and / or broadcast messages according to the indication of the target time information, i.e., stops receiving Paging messages and / or PDCCH and / or broadcast messages.

[0211] The implementation process on the satellite network equipment side includes:

[0212] Step S111: Obtain the context of the terminal at time T0.

[0213] It should be noted that this step is optional.

[0214] Step S112: The onboard network device and the terminal perform data transmission;

[0215] Step S113: After the onboard network device determines that there is no data interaction between the terminal and the onboard network device (for example, there is no data transmission of the terminal or the security has not been verified), a first message is sent to the terminal, where the first message may be an RRC release message (RRCRelease) message, and the first message may be in an unencrypted or unintegrity-guaranteed state, indicating that the terminal enters an RRC_IDLE state or an RRC_INACTIVE state, and carries target time information in the first message, where the target time information may be in any of the following ways:

[0216] Method 1: starting time and / or preset time length, for example, the starting time can be UTC time, and the preset time length can be in hours, minutes, seconds, etc.;

[0217] Method 2: Deadline, for example, the deadline can be UTC time;

[0218] Mode three: a first time list, wherein the first time list includes one or more time windows.

[0219] Optionally, the target time information may be configured according to the following information:

[0220] The service characteristics of the terminal, such as the service cycle and the amount of data;

[0221] Satellite ephemeris information, such as time information when the next satellite can provide coverage to the terminal, or time when the next satellite can provide coverage to the first geographical location area;

[0222] Indication of core network equipment.

[0223] It should be noted that the first geographical location may be a geographical location range, such as a sea area, a tropical rain forest, a grassland, etc., and the shape may be irregular. The first geographical location may be described by the center and radius of a circle, and the center of the circle may be a longitude and latitude coordinate; or it may be an irregular shape drawn by multiple points, such as a series of points of geographical location coordinates (such as longitude and latitude coordinates), and the description method of connecting these points.

[0224] Step S114: The onboard network device stops sending Paging messages and / or PDCCH and / or broadcast messages to the terminal within the time range indicated by the target time information until the terminal initiates UL access or receives an instruction from the core network device.

[0225] Optionally, the onboard network device may stop updating the broadcast message or ephemeris information to the terminal within the time range indicated by the target time information.

[0226] The implementation process on the terminal side includes:

[0227] Step S121: The terminal receives a first message, which may be an RRCRelease message, and enters the RRC_IDLE state or the RRC_INACTIVE state. The first message carries target time information, which may be:

[0228] Method 1: starting time and / or preset time length, for example, the starting time can be UTC time, and the preset time length can be in hours, minutes, seconds, etc.;

[0229] Method 2: Deadline, for example, the deadline can be UTC time.

[0230] Mode three: a first time list, wherein the first time list includes one or more time windows.

[0231] The terminal may be a terminal in a first geographical location area.

[0232] The first geographical location may be a geographical location range, such as a sea area, a tropical rain forest, a grassland, etc., and the shape may be irregular. The first geographical location may be described by a circle center + radius, where the circle center may be a longitude and latitude coordinate; or may be an irregular shape drawn by multiple points, such as a series of geographical location coordinates (such as longitude and latitude coordinates) connected to describe these points.

[0233] Step S122: After receiving the target time information, the terminal stops receiving Paging messages and / or PDCCH and / or broadcast messages.

[0234] The terminal can stop receiving Paging messages and / or PDCCH and / or broadcast messages in the following three ways:

[0235] Method 1:

[0236] When the target time information includes a start time and / or a preset time length, the terminal starts the target timer at the start time and sets its length to the preset time length; the terminal no longer receives Paging messages and / or PDCCH and / or broadcast messages during the operation of the target timer.

[0237] Method 2:

[0238] When the target time information is the cutoff time, the terminal no longer receives the Paging message and / or the PDCCH and / or the broadcast message after receiving the first message.

[0239] Method three: when the target time information is the first time list, stop receiving the Paging message and / or PDCCH and / or broadcast message outside one or more time windows indicated by the first time list.

[0240] Optionally, if the terminal enters the RRC connected state or performs EDT / SDT transmission during the operation of the target timer or before the deadline, for example, UL data arrives or small data arrives, and the terminal enters the RRC connected state, then the terminal updates the target time information to the initialized value, and the update is performed in the following manner:

[0241] Method 1: When the target time information includes a start time and / or a preset time length, the terminal stops the target timer when entering the connected state and sets the target timer to an invalid value, such as a negative value.

[0242] Method 2: When the target time information is a deadline, the terminal sets the deadline to an invalid value.

[0243] Application scenario 2: The onboard network device (also called a satellite) notifies the terminal in a broadcast message to stop receiving Paging messages and / or PDCCH time-related information

[0244] The implementation process on the satellite network equipment side includes:

[0245] Step S211: The onboard network device indicates target time information in a broadcast message. The target time information may be:

[0246] Method 1: starting time and / or preset time length, for example, the starting time can be UTC time, and the time length can be in hours, minutes, seconds, etc.;

[0247] Method 2: Deadline, for example, the deadline can be UTC time;

[0248] Mode three: a first time list, wherein the first time list includes one or more time windows.

[0249] The target time information may be bound to a cell, and the specific IE structure is as follows (wherein timeInfo in the IE is the target time information):

[0250]

[0251] Or, the target time can be bound to the ephemeris information, and the specific IE structure is as follows (wherein, ephemerisInfo in IE is the ephemeris information:

[0252]

[0253] Optionally, the target time information may be configured according to the following information:

[0254] The service characteristics of the terminal, such as the service cycle and the amount of data;

[0255] Satellite ephemeris information, such as time information when the next satellite can provide coverage to the terminal, or time when the next satellite can provide coverage to the first geographical location area;

[0256] Indications for core network equipment;

[0257] Step S212: The onboard network device stops sending Paging messages and / or PDCCH and / or broadcast messages to the terminal within the time range indicated by the target time information.

[0258] Optionally, the onboard network device may stop updating the broadcast message or ephemeris information to the terminal within the time range indicated by the target time information.

[0259] The implementation process on the terminal side includes:

[0260] Step S221: The terminal receives a broadcast message, wherein the broadcast message carries target time information.

[0261] Optionally, the target time information may be bound to the cell information, and when the terminal receives the specific IE structure, it will bind different PhyCellIDs to the target time information.

[0262] If the terminal is instructed to perform data transmission on the first cell subsequently, the terminal will associate the first cell with the target time information.

[0263] The first cell information may be determined through dedicated signaling, such as an RRC Release message or an RRC Reconfiguration message, or a cell selected when the terminal accesses for the first time.

[0264] Optionally, the target time information may be bound to the ephemeris information. When receiving the specific IE structure, the terminal will bind different ephemerisInfo (ephemeris information) to the target time information.

[0265] If the terminal is instructed to subsequently perform data transmission on the on-board network device corresponding to the first ephemeris information, the terminal associates the cell corresponding to the first ephemerisInfo with the target time information.

[0266] The first ephemeris information may be determined through dedicated signaling, such as an RRC Release message or an RRC Reconfiguration message, or a satellite selected when the terminal accesses for the first time.

[0267] Step S222: After receiving the target time information, the terminal stops receiving Paging messages and / or PDCCH and / or broadcast messages.

[0268] The terminal can stop receiving Paging messages and / or PDCCH and / or broadcast messages in the following three ways:

[0269] Method 1:

[0270] When the target time information includes a start time and / or a preset time length, the terminal starts the target timer at the start time and sets its length to the preset time length; the terminal no longer receives Paging messages and / or PDCCH and / or broadcast messages during the operation of the target timer.

[0271] Method 2:

[0272] When the target time information is the cutoff time, the terminal no longer receives the Paging message and / or the PDCCH and / or the broadcast message after receiving the first message.

[0273] Method three: when the target time information is the first time list, stop receiving the Paging message and / or PDCCH and / or broadcast message outside one or more time windows indicated by the first time list.

[0274] Optionally, if the terminal enters the RRC connected state during the operation of the target timer or before the deadline, for example, UL data arrives and the terminal enters the RRC connected state, the terminal updates the target time information to the initialized value, and the update is performed in the following manner:

[0275] Method 1: When the target time information includes a start time and / or a preset time length, the terminal stops the target timer when entering the connected state and sets the target timer to an invalid value, such as a negative value.

[0276] Method 2: When the target time information is a deadline, the terminal sets the deadline to an invalid value.

[0277] Application 3: Indicating target time information through non-secure encrypted RRC release message

[0278] like Figure 3 As shown, the specific implementation process includes:

[0279] Step 301: The terminal establishes an RRC connection with an onboard network device;

[0280] Step 302: The terminal sends a registration request message to the onboard network device;

[0281] Step 303: The onboard network device sends a UL NAS transmission message to the core network device;

[0282] For example, the core network device is AMF. The UL NAS transmission message carries a registration request (RegistrationRequest) of the terminal.

[0283] Step 304: the on-board network device sends a non-secure encrypted RRCRelease message to the terminal;

[0284] It should be noted that since the terminal security is not established, the terminal cannot transmit DRB data or receive DL data. In order to save power, the terminal can no longer listen to Paging messages. At this time, the network sends a non-secure encrypted RRCRelease message to the terminal; the terminal does not perform integrity protection verification or RRC security verification. After receiving the RRCReleae message, the terminal enters the RRC_IDLE or RRC INACTIVE state.

[0285] It should be noted that the terminal may be a notification message receiving an onboard network device, wherein the notification message is used to indicate that the satellite cannot provide a feeder link, or the terminal may determine whether to enter the RRCIDLE or RRC INACTIVE state based on the current transmission data state, for example, before the terminal receives a registration accept message, based on a non-securely encrypted RRCRelease message.

[0286] It should be noted that the non-securely encrypted RRCRelease message carries the target time information, and the terminal does not receive paging messages, PDCCH and / or broadcast messages after entering the RRCIDLE or RRC INACTIVE state.

[0287] Step 305: The core network device feeds back a DL NAS message, which carries an authentication request;

[0288] Step 306: The terminal performs RRC connection establishment according to the timer or paging, and enters the RRC connection state again;

[0289] Step 307: The onboard network device transmits an authentication request;

[0290] Step 308: The terminal sends an authentication response;

[0291] Step 309: The onboard network device transparently transmits the authentication response to the core network device;

[0292] Step 310: Same as step 304;

[0293] Step 311: The core network device feeds back a NAS security mode command according to the authentication response;

[0294] Step 312: The terminal establishes an RRC connection;

[0295] Step 313: The onboard network device sends a NAS security mode command to the terminal;

[0296] Step 314: The terminal sends an encrypted registration request;

[0297] Step 315: The onboard network device sends the registration request to the core network device;

[0298] Step 316: Same as step 304;

[0299] Step 317: The core network device encrypts the registration acceptance message to the onboard network device;

[0300] Step 318: The terminal executes the RRC establishment process;

[0301] Step 319: The onboard network device sends an encrypted registration acceptance message to the terminal.

[0302] Step 320: The terminal sends a security mode completion message of the RRC layer;

[0303] Step 321: The onboard network device sends an RRC reconfiguration message to the terminal;

[0304] Step 322: The terminal sends an RRC reconfiguration completion message to the onboard network device;

[0305] Step 323: The terminal performs DRB data transmission process with the onboard network device;

[0306] Step 324: The onboard network device sends the encrypted RRCRelease message to the terminal;

[0307] Furthermore, the terminal enters the RRC_IDLE / RRC_INACTIVE state according to the encrypted RRCRelease message.

[0308] Application Scenario 4: Instructing the terminal to enter the target state

[0309] like Figure 4 As shown, the specific implementation process includes:

[0310] Step 401: The terminal establishes an RRC connection with an onboard network device;

[0311] Step 402: The terminal sends a registration request message to the onboard network device;

[0312] Step 403: The onboard network device sends a UL NAS transmission message to the core network device;

[0313] For example, the core network device is AMF

[0314] Step 404: The core network device sends an authentication request to the onboard network device;

[0315] Step 405: The onboard network device sends a target indication to the terminal, where the target indication is used to instruct the terminal to enter a target state, for example, a temporary state. When the terminal is in the target state, the terminal does not listen to Paging messages and / or PDCCH and / or broadcast messages. The time length of the target state may be indicated by target time information, and the target time information and the target indication are included together in a first message and sent to the terminal.

[0316] Step 406: When the target timer times out or reaches the deadline, the terminal listens to the Paging message and / or PDCCH message and / or broadcast message, or the terminal directly initiates the RRC establishment process and performs the CBRA process.

[0317] Specifically, when the target time information includes a start time and / or a preset time length, a target timer is started at the start time, and the target state is entered within the target timer running time, and the timing duration of the target timer is the preset time length; or

[0318] In the case where the target time information includes a deadline, the target state is entered within a time range between the time when the first message is received and the deadline.

[0319] Step 407: The onboard network device sends a NAS authentication request to the terminal;

[0320] Step 408: The terminal sends a NAS authentication response to the onboard network device;

[0321] Step 409: The onboard network device sends a NAS authentication response to the core network device;

[0322] Step 410: The core network device feeds back a NAS security mode command according to the NAS authentication response;

[0323] Step 411-step 412: same as step 405 and step 406;

[0324] Step 413: The onboard network device sends a NAS security mode command to the terminal;

[0325] Step 414: The terminal sends an encrypted registration request;

[0326] Step 415: The onboard network device sends the registration request to the core network device;

[0327] Step 416: Same as step 405;

[0328] Step 417: The core network device encrypts the registration acceptance message to the onboard network device;

[0329] Step 418: Same as step 406; the terminal enters the RRC establishment process and sends the encrypted registration acceptance.

[0330] Step 419: The onboard network device sends a NAS registration acceptance message to the terminal;

[0331] Step 420: The terminal feeds back a security mode completion message to the onboard network device;

[0332] The terminal sends a security mode completion message of the RRC layer;

[0333] Step 421: The onboard network device sends an RRC reconfiguration message to the terminal;

[0334] Step 422: The terminal sends an RRC reconfiguration completion message to the onboard network device;

[0335] Step 423: The terminal performs DRB data transmission process with the onboard network device;

[0336] Step 424: the onboard network device sends the encrypted RRCRelease message to the terminal;

[0337] Furthermore, the terminal enters the RRC_IDLE / RRC_INACTIVE state according to the encrypted RRCRelease message.

[0338] It should be noted that the embodiments of the present application can stop receiving paging messages, PDCCH and / or broadcast messages within a specific time range based on the instructions of the onboard network equipment, thereby solving the problem of power consumption of the terminal when the satellite is in the S&F scenario, thereby saving terminal power consumption.

Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.

[0343] like Figure 5 As shown, an embodiment of the present application provides an information transmission method, which is executed by an on-board network device, including:

[0344] Step S501, after determining that there is no data interaction between the terminal and the on-board network device, sending a first message to the terminal, wherein the first message carries target time information;

[0345] The first message is used to instruct the terminal to stop receiving indication information within the time range indicated by the target time information, and the indication information includes at least one of the following: a paging message, a physical downlink control channel PDCCH, and a broadcast message.

[0478] Implementation method 1:

[0479] The main behaviors on the terminal side are as follows:

[0481] Receiving a non-secure encrypted RRC release message sent by an onboard network device;

[0482] According to the RRC release message, enter the RRC idle state or the RRC inactive state.

[0483] That is to say, in this case, as long as the terminal receives a non-securely encrypted RRC release message, it will not process the RRC release message and directly enter the RRC idle state or RRC inactive state, thereby reducing the signaling processing overhead.

[0484] Optionally, the terminal does not receive indication information in the RRC idle state or the RRC inactive state, and the indication information includes at least one of the following: a paging message, a physical downlink control channel PDCCH, and a broadcast message.

[0485] It should be noted that when the terminal enters the RRC idle state or the RRC inactive state through an RRC release message based on non-secure encryption, the terminal does not receive the indication information, thereby reducing the terminal's listening power consumption and saving the terminal's power consumption.

[0486] Optionally, before entering the RRC idle state or the RRC inactive state according to the RRC release message, the method further includes:

[0487] Under target conditions, determining not to perform decryption or integrity verification on the RRC release message;

[0507] In the case where it is determined to exit the target state, the indication information is received.

[0508] It should be noted that when the terminal exits the target state, the terminal resumes the behavior before entering the target state, thereby ensuring that the terminal can resume communication and perform communication services.

[0509] For satellite network equipment, it specifically includes:

[0510] An information transmission method, executed by an on-board network device, comprising:

[0511] A target indication is sent to the terminal, where the target indication is used to indicate that the terminal enters a target state, where the terminal stops receiving indication information, where the indication information includes at least one of the following: a paging message, a physical downlink control channel PDCCH, and a broadcast message.
