[0114] In some embodiments, the first network element is intended to support network automation and intelligence, optimize network performance, manage network resources, and provide better user experience by analyzing and utilizing network data.

[0115] In some embodiments, the NWDAF is a key component in the fifth generation (5G) network architecture, which is defined in the 5G standard by the 3rd generation partnership project (3GPP).

[0116] In some embodiments, the second network element is used for access control and mobility management of terminal access to the operator network, for example, including functions such as mobile state management, allocation of user temporary identity, authentication and authorization of users, and the name is not limited thereto.

[0117] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed by the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems.

[0118] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1, or part of the subject, but are not limited thereto. The subjects shown in FIG. 1 are exemplary, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than FIG. 1. The number and form of each subject is arbitrary, each subject can be physical or virtual, the connection relationship between each subject is exemplary, each subject can not be connected or can be connected, the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0119] Embodiments of the present disclosure can be applied to long term evolution (LTE), LTE-advanced (LTE-A), LTE-beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new-radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), global System for mobile communications (GSM (registered trademark)), CDMA2000, ultra mobile broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, ultra-wide band (UWB), bluetooth (bluetooth (registered trademark)), public land mobile network (PLMN) network, device-to-device (D2D) system, machine to machine (M2M) system, internet of things (IoT) system, vehicle-to-everything (V2X), system using other communication methods, next-generation system expanded based on them, and the like. In addition, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0120] It should be noted that the cell selection by the terminal in the embodiments of the present disclosure includes cell initial selection and cell reselection. The cell initial selection can be understood as initially selecting a cell without accessing the cell, and the cell reselection can be understood as reselecting a cell with accessing the cell.

[0121] It should be further explained that in the embodiments of the present disclosure, the terminal performs cell selection, and the cell selection can be performed from the serving cell and the neighbor cell. The cell selection is to perform measurement on the serving cell and / or the neighbor cell, for example, radio resource management (RRM) measurement.

[0122] In some embodiments, a NTN (Non-terrestrial Network) provides wireless resources through a satellite (or a drone) instead of a ground base station, and the architecture is as shown in FIG. 2A.

[0123] Depending on the way the satellite processes the signal, it can be divided into a transparent mode and a regenerative mode. The transparent mode is as shown in FIG. 2B. The NTN ground station sends the base station signal to the satellite, and the satellite converts the signal to the satellite frequency band and then sends it to the terminal (also known as terminal device) through the satellite frequency band. Except for frequency conversion and signal amplification, the satellite does not demodulate the base station signal.

[0124] The regenerative mode is as shown in FIG. 2C. The NTN ground station sends the base station signal to the satellite, and the satellite first demodulates and decodes the signal and then re-encodes and modulates it, and sends the regenerated signal through the satellite frequency band.

[0125] In the related art, the working mode of the network device only supports the non- store-and-forward mode. In the case where the working mode of the network device supports the store-and-forward mode and the non-store-and-forward mode, the terminal is not aware of the working mode of the network device, which affects the communication quality.

[0126] Therefore, the network device can send the indication information to the terminal to indicate the working mode information for data transmission, so that the terminal can perform a communication process matched with the working mode information of the network device according to the working mode information indicated by the network device, and ensure the communication quality.

[0127] FIG. 3A is an interaction schematic diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG. 3A, the present disclosure relates to an information indication method, and the above method includes:

[0128] S301A, the network device sends indication information to the terminal.

[0129] The indication information is used to indicate at least one of the following information of the network device for data transmission: a working mode; time information corresponding to the working mode; and the working mode is a store and forward mode or a non-store and forward mode.

[0130] In the embodiments of the present disclosure, the network device sends the indication information to the terminal by itself, or sends the indication information to the terminal based on a protocol agreement, or sends the indication information to the terminal based on a request of the terminal.

[0131] In the embodiments of the present disclosure, the network device sends the indication information to the terminal by using new signaling, or sends the indication information to the terminal by multiplexing existing signaling.

[0132] The existing signaling can be multiplexed to send the indication information to the terminal while sending information that needs to be indicated to the terminal.

[0133] In some embodiments, the network device sends the indication information to the terminal, including: sending a system information block (SIB) to the terminal, wherein the SIB includes the indication information.

[0134] For example, the network device sends a SIB31 to the terminal, wherein the SIB31 includes the indication information.

[0135] The working mode information is used to indicate at least one of the following: the working mode is a store and forward mode; the working mode is a non-store and forward mode; and time information corresponding to the working mode.

[0136] In the embodiments of the present disclosure, the indication information is used to indicate that the working mode of the network device is a store and forward mode. For example, the indication information indicates that the store and forward mode is enabled, or the indication information indicates that the store and forward mode is present.

[0137] In the embodiments of the present disclosure, the indication information is used to indicate that the working mode of the network device is a non-store and forward mode. For example, the indication information indicates that the store and forward mode is disabled, or the indication information indicates that the store and forward mode is absent.

[0138] In the embodiments of the present disclosure, the indication information is used to indicate that the working mode of the network device is a store and forward mode, and the time information corresponding to the working mode.

[0139] In the embodiments of the present disclosure, the indication information is used to indicate that the working mode of the network device is a non-store and forward mode, and the time information corresponding to the working mode.

[0140] In the embodiments of the present disclosure, the indication information is used to indicate that the working mode of the network device is the non-store-and-forward mode and the store-and-forward mode, and corresponding time information when the working mode is the non-store-and-forward mode and corresponding time information when the working mode is the store-and-forward mode.

[0141] In the embodiments of the present disclosure, the network device can store data in the store-and-forward mode, and the network device cannot store data in the non-store-and-forward mode.

[0142] It should be noted that the non-store-and-forward mode can also be referred to as the normal mode or the ordinary mode.

[0143] The store-and-forward mode can be applied to data transmission in satellite communication. The store-and-forward mode is suitable for scenarios where real-time communication cannot be achieved or the communication link is unstable, such as ocean monitoring, environmental monitoring, remote medical treatment, disaster response, and the like. The store-and-forward mode can also achieve effective data transmission when the network device and the data receiving node (such as a ground node or a terminal) do not have a stable real-time communication link.

[0144] In some embodiments, the working process of the store-and-forward mode generally includes the following steps:

[0145] For the working process of terminal uplink data transmission, the terminal sends data to the network device (such as a satellite). If the network device and the ground node (such as a gateway) do not have a connection at this time, for example, there is no feeder link, the network device stores the data sent by the terminal. When the network device and the ground node have a connection, for example, there is a feeder link, the network device forwards the stored data sent by the terminal to the ground node (such as a gateway). The ground node receives the data sent by the network device and successfully receives the data sent by the terminal.

[0146] For the working process of terminal downlink data reception, the ground node (gateway or data network) prepares to send data to the terminal. At this time, the ground node sends data to the network device. If there is no connection between the network device and the terminal at this time, for example, there is no service link, the network device buffers the data. When the network device and the terminal establish a connection (there is a service link), the data is sent to the terminal again. The terminal completes the downlink data reception.

[0147] It can be understood that, in the case that the working mode of the network device is the store-and-forward mode, the network device comprises at least one of the following functions: a base station (gNB); a base station and a core network, a base station and a part of a core network network (a mobility management entity (MME) split architecture, for example, functions of the core network except for a home subscriber server (HSS) are on the network device).

[0148] In the embodiments of the present disclosure, the working mode of the network device is the store-and-forward mode, which can overcome geographical limitations: since the network device can cover anywhere on the earth, communication in remote areas or moving targets can be realized. It can cope with unstable communication links: in the case of unstable or unavailable communication links, data can be temporarily stored on the network device until the link is restored for transmission. Batch data transmission can be realized: the network device can collect a large amount of data and then transmit them at one time when appropriate, which can improve communication efficiency.

[0149] In the embodiments of the present disclosure, in the store-and-forward mode, the network device can pre-store data in the case of disconnection with the ground node or terminal, and send the stored data in the case of restoring the connection. In the non-store-and-forward mode, the network device cannot store data in the case of disconnection with the ground node or terminal, which will cause the data to be unable to be accurately sent to the ground node or terminal.

[0150] In some embodiments, the time information corresponding to the working mode is used to indicate an end time corresponding to the working mode, or a duration corresponding to the working mode, or a switching time corresponding to the working mode.

[0151] In the embodiments of the present disclosure, the indication information sent by the network device to the terminal indicates the time information corresponding to the working mode, which can indicate the end time corresponding to the working mode, or the duration corresponding to the working mode, or the switching time corresponding to the working mode.

[0152] Exemplarily, the indication information sent by the network device to the terminal indicates that the working mode is the store-and-forward mode, and the end time corresponding to the working mode is the first time, which can be understood as the indication information indicating that the working mode of the network device is the store-and-forward mode, and the network device works in the store-and-forward mode until the first time, that is, after the first time, the working mode of the network device will not be the store-and-forward mode.

[0153] Exemplarily, the indication information sent by the network device to the terminal indicates that the working mode is the store-and-forward mode, and the duration corresponding to the working mode can be understood as the indication information indicating that the working mode of the network device is the store-and-forward mode, and the duration of the network device continuing to work in the store-and-forward mode.

[0154] Exemplarily, the indication information sent by the network device to the terminal indicates that the working mode is the store-and-forward mode, and the switching time corresponding to the working mode is the first moment, which can be understood as the indication information indicating that the working mode of the network device is the store-and-forward mode and at the first moment, the working mode of the network device will be switched to the non-store-and-forward mode.

[0155] Exemplarily, the indication information sent by the network device to the terminal indicates that the working mode is the store-and-forward mode and the non-store-and-forward mode, and the end time corresponding to the working mode in the store-and-forward mode is the first moment, the end time corresponding to the working mode in the non-store-and-forward mode is the second moment, and the second moment is after the first moment, which can be understood as the indication information indicating that the working mode of the network device in the store-and-forward mode ends at the first moment, that is, the network device will work in the non-store-and-forward mode after the first moment, and the network device working in the non-store-and-forward mode ends at the second moment.

[0156] Exemplarily, the indication information sent by the network device to the terminal indicates that the working mode is the store-and-forward mode and the non-store-and-forward mode, and the duration corresponding to the working mode can be understood as the indication information indicating that the working mode of the network device is the store-and-forward mode and the duration in the mode, and the network device working in the non-store-and-forward mode and the duration in the mode.

[0157] Exemplarily, the indication information sent by the network device to the terminal indicates that the working mode is the store-and-forward mode and the non-store-and-forward mode, and the switching time corresponding to the working mode in the store-and-forward mode is the first moment, the switching time corresponding to the working mode in the non-store-and-forward mode is the second moment, and the second moment is after the first moment, which can be understood as the indication information indicating that the working mode of the network device is switched to the non-store-and-forward mode at the first moment, and the working mode of the network device is switched to the store-and-forward mode at the second moment.

[0158] It should be noted that the above examples take the working mode as the store-and-forward mode as an example, and the working mode can also be the non-store-and-forward mode.

[0159] S302A, the indication information sent by the network device to the terminal is carried by the SIB, and the working mode of the network device changes, and the network device determines to perform at least one of the following: not updating a system information value tag systemInfoValueTag of the SIB; not initiating a system message change notification procedure; or the network device determines whether the SIB changes without considering whether the working mode of the network device changes.

[0160] In the embodiments of the present disclosure, the indication information sent by the network device to the terminal is carried by the SIB, wherein the indication information is used to indicate the working mode of the network device for data transmission, and in the case that the working mode of the network device changes, the network device can not update the systemInfoValueTag of the SIB and / or not initiate the system message change notification procedure.

[0161] It can be understood that generally, in the case that the information indicated by the SIB changes, the network device can update the systemInfoValueTag of the SIB, initiate the system message change notification procedure, and notify the terminal that the information indicated by the SIB changes. In the embodiments of the present disclosure, the terminal can determine when the working mode of the network device changes according to the time information corresponding to the working mode indicated by the indication information sent by the network device. Since the terminal can determine when the working mode of the network device changes, the network device can not update the systemInfoValueTag of the SIB and / or not initiate the system message change notification procedure in the case that the working mode changes, thereby saving communication overhead and improving communication efficiency.

[0162] In the embodiments of the present disclosure, the network device determines whether the SIB changes without considering whether the working mode of the network device changes.

[0163] It can be understood that generally, in the case that the information indicated by the SIB changes, the network device can update the systemInfoValueTag of the SIB, initiate the system message change notification procedure, and notify the terminal that the information indicated by the SIB changes. In the embodiments of the present disclosure, the terminal can determine when the working mode of the network device changes according to the time information corresponding to the working mode indicated by the indication information sent by the network device. Since the terminal can determine when the working mode of the network device changes, the network device can not update the systemInfoValueTag of the SIB and / or not initiate the system message change notification procedure in the case that the working mode changes, thereby saving communication overhead and improving communication efficiency.

[0164] S303A, the working mode of the network device is the non- store-and-forward mode, and the network device determines the first parameter according to time information corresponding to the non- store-and-forward mode.

[0165] The first parameter is used to indicate time information in which the network device stops providing services.

[0166] The order of S303A and S302A can be exchanged or executed at the same time, and the embodiments of the present disclosure do not make specific limitations on this.

[0167] In the embodiments of the present disclosure, when the working mode of the network device is the non- store-and-forward mode, the network device determines the first parameter t-service according to time information corresponding to the non- store-and-forward mode.

[0168] The first parameter t-service is time information about when the NTN cell stops providing services for the current coverage area. This field is applicable to the switching of service links in NTN fixed cells and the switching of feeder links in NTN fixed cells and NTN mobile cells.

[0169] In the embodiments of the present disclosure, the network device determines the first parameter t-service according to time information corresponding to the non- store-and-forward mode, and can set the first parameter t-service to the same time as the time indicated by the time information corresponding to the non- store-and-forward mode.

[0170] For example, if the time information corresponding to the non- store-and-forward mode is the end time of the end of the mode, t-service is set to the same time as the end time.

[0171] For example, if the time information corresponding to the non- store-and-forward mode is the duration of time to the end of the mode, the network device can set t-service to the same time as the end of the duration of time of the non- store-and-forward mode by calculation.

[0172] For example, if the time information corresponding to the non- store-and-forward mode is the switching time to switch to another mode at the end of the mode, the network device can set the first parameter t-service to the same time as the switching time indicated by the time information corresponding to the non- store-and-forward mode.

[0173] S304A, the network device sends the first parameter to the terminal.

[0174] In the embodiments of the present disclosure, after the network device determines the first parameter t-service, the network device can send the first parameter t-service to the terminal.

[0175] The network device sends the first parameter t-service to the terminal by itself, or sends the first parameter t-service to the terminal based on a protocol agreement, or sends the first parameter t-service to the terminal based on a request of the terminal.

[0176] In S305A, the terminal supports the store-and-forward mode, and the terminal ignores the first parameter or does not perform cell reselection according to the first parameter; or the terminal does not support the store-and-forward mode, and the terminal determines to perform cell reselection according to the first parameter.

[0177] It can be understood that the terminal supports the store-and-forward mode, that is, the terminal supports the network device working in the store-and-forward mode, the terminal does not support the store-and-forward mode, and the terminal does not support the network device working in the store-and-forward mode.

[0178] In the embodiment of the present disclosure, the network device works in the non-store-and-forward mode, switches to the store-and-forward mode at the time indicated by the time information corresponding to the non-store-and-forward mode, and sets the time of the first parameter to be the same as the time indicated by the time information corresponding to the non-store-and-forward mode, that is, the first parameter sent by the network device indicates that the network device will stop providing services at the time indicated by the time information corresponding to the non-store-and-forward mode. In general, the terminal will perform cell reselection according to the first parameter, but actually, the network device switches to the store-and-forward mode at the time indicated by the time information corresponding to the non-store-and-forward mode, and can provide services for the terminal supporting the store-and-forward mode. Optionally, in the case that the terminal supports the store-and-forward mode, the first parameter can be ignored or cell reselection is not performed according to the first parameter, so that the terminal is not limited by the time indicated by the time information indicating that the network device stops providing services, and can still access the network as needed within the time indicated by the time information indicating that the network device stops providing services, thereby guaranteeing the communication quality.

[0179] In the embodiment of the present disclosure, the working mode of the network device is switched from the non-store-and-forward mode to the store-and-forward mode at the time indicated by the time information corresponding to the working mode (that is, the first parameter), the terminal receives the first parameter sent by the network device, and if the terminal does not support the store-and-forward mode, the network device cannot provide services for the terminal when the working mode of the network device is switched to the store-and-forward mode, and the terminal can perform cell reselection, which includes performing service cell and / or neighbor cell measurement, thereby guaranteeing the communication quality.

[0180] Exemplarily, the working mode of the network device is the non- store-and-forward mode, the time information corresponding to the working mode indicates that the working mode of the network device will be switched to the store-and-forward mode at the first time point in the future, the network device sets the first parameter as the first time point, that is, the network device will stop providing services at the first time point. After the network device sets the first parameter as the first time point, the network device sends the first parameter to the terminal. If the terminal supports the store-and-forward mode, the network device will be switched to the store-and-forward mode after the first time point, and can provide services for the terminal, so the terminal can ignore the first parameter or not perform cell reselection according to the first parameter; but if the terminal does not support the store-and-forward mode, the network device cannot provide services for the terminal when the working mode of the network device is switched to the non-store-and-forward mode, so the terminal can perform cell reselection according to the first parameter, which can guarantee the communication quality.

[0181] Optionally, the terminal performs cell reselection according to the first parameter can perform cell (serving cell and / or neighbor cell) measurement, and select a target cell for cell switching according to the result of the cell measurement.

[0182] It can be understood that the terminal receives the indication information sent by the network device, and if it is determined according to the time information corresponding to the working mode indicated by the indication information that the working mode of the network device is switched, the indication information can be reacquired according to the time indicated by the time information corresponding to the working mode.

[0183] The indication information is reacquired at the time indicated by the time information corresponding to the working mode, or before or after the time.

[0184] S306A, the terminal sends a first message to the network device.

[0185] The first message is sent by the terminal in the case where it is determined according to the time information corresponding to the working mode that the working mode of the network device is switched, and the first message is used to instruct the network device to resend the indication information.

[0186] The order of S306A and S302A can be exchanged or executed at the same time, the order of S306A and S303A can be exchanged or executed at the same time, the order of S306A and S304A can be exchanged or executed at the same time, the order of S306A and S305A can be exchanged or executed at the same time, and the embodiments of the present disclosure do not make specific limitations on this.

[0187] In the embodiments of the present disclosure, the terminal receives the indication information sent by the network device, and in the case that the indication information is used to indicate time information corresponding to the working mode of the network device for data transmission, the terminal can determine the time when the network device switches the working mode according to the time information corresponding to the working mode, and then sends the first message to the network device to request the network device to resend the indication information in the case that the working mode of the network device is switched, and the working mode and / or the time information corresponding to the working mode of the network device for data transmission after the indication.

[0188] In some embodiments, the terminal sends the first message to the network device before the time indicated by the time information corresponding to the working mode indicated by the indication information; or the terminal sends the first message to the network device at the time indicated by the time information corresponding to the working mode indicated by the indication information; or the terminal sends the first message to the network device after the time indicated by the time information corresponding to the working mode indicated by the indication information.

[0189] By implementing the embodiments of the present disclosure, the network device can send the indication information to the terminal to indicate the working mode information for data transmission, so that the terminal can perform the communication process matched with the working mode information of the network device according to the working mode information indicated by the network device, and ensure the communication quality.

[0207] Figure 3B is an interaction diagram of an information indication method according to an embodiment of the present disclosure. As shown in Figure 3B, the embodiment of the present disclosure relates to an information indication method, and the method comprises:

[0208] S301B, the network device sends indication information to the terminal.

[0209] The indication information is used to indicate at least one of the following information of the network device for data transmission: working mode; time information corresponding to the working mode; wherein the working mode is a store-and-forward mode or a non-store-and-forward mode.

[0210] The optional implementation of S301B can refer to the optional implementation of S301A of Figure 3A and other related parts in the embodiments involved in Figure 3A, which will not be repeated here.

[0211] In some embodiments, the network device sends indication information to the terminal, comprising: sending a system information block (SIB) to the terminal, wherein the SIB comprises the indication information.

[0212] The working mode information is used to indicate at least one of the following: the working mode is a store-and-forward mode; the working mode is a non-store-and-forward mode; time information corresponding to the working mode.

[0213] In some embodiments, the time information corresponding to the working mode is used to indicate an end time corresponding to the working mode, or a duration corresponding to the working mode, or a switching time corresponding to the working mode.

[0214] It can be understood that different terminals can have different behaviors in different working modes of the network device, for example, considering the following several different types of terminals: legacy terminal: a terminal before version 19, which does not support the capability of store-and-forward mode and cannot recognize the indication information provided by the network device to indicate the working mode information of the network device for data transmission; a terminal of version 19 but not supporting the capability of store-and-forward mode; a terminal of version 19 and later versions, supporting the capability of store-and-forward mode and being able to recognize the indication information provided by the network device to indicate the working mode information of the network device for data transmission.

[0215] S302B, the terminal is in the RRC connected state, and in the case that the working mode of the network device is the non-store-and-forward mode, the terminal enters the RRC non-connected state before the network device switches to the store-and-forward mode according to the time information corresponding to the non-store-and-forward mode.

[0216] Optionally, the terminal is in the RRC connected state, the working mode of the network device is the non-store-and-forward mode, and the terminal enters the RRC non-connected state before the working mode of the network device switches to the store-and-forward mode.

[0217] In the embodiments of the present disclosure, the terminal receives the indication information sent by the network device, and in the case that the indication information indicates that the working mode of the network device is the non-store-and-forward mode and the time information corresponding to the working mode indicates that the working mode of the network device will switch from the non-store-and-forward mode to the store-and-forward mode at a time, if the terminal is in the RRC connected state and does not support the store-and-forward mode, the terminal can determine to enter the RRC non-connected state before the network device switches to the store-and-forward mode, so as to guarantee the communication quality.

[0218] Exemplarily, the terminal receives the indication information sent by the network device, wherein the indication information is used to indicate that the working mode of the network device is the non-store-and-forward mode and the time information corresponding to the working mode indicates that the working mode of the network device will switch to the store-and-forward mode at a first time, in this case, the terminal is in the RRC connected state and does not support the store-and-forward mode, and the network device will not be able to provide services for the terminal after the first time, so the terminal can switch to the RRC non-connected state at or before the first time or after the first time, so as to guarantee the communication quality.

[0219] Exemplarily, if the working mode of the network device is the non-store-and-forward mode, the terminal in the RRC connected state can determine when the non-store-and-forward mode of the network device ends according to the time information corresponding to the working mode, and the terminal is switched to the RRC non-connected state at the end of the non-store-and-forward mode, or before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode.

[0220] Exemplarily, if the working mode of the network device is the non-store-and-forward mode, the terminal in the RRC connected state can determine when the non-store-and-forward mode of the network device ends according to the time information corresponding to the working mode, and the terminal is switched to the RRC non-connected state at the end of the non-store-and-forward mode, or before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode.

[0221] Exemplarily, the RRC non-connected state includes the RRC idle state and / or the RRC inactive state.

[0222] S303B, the working mode of the network device is the non-store-and-forward mode, and the network device determines to switch the terminal in the RRC connected state to the RRC non-connected state according to the time information corresponding to the non-store-and-forward mode before the working mode is switched to the store-and-forward mode; or the working mode of the network device is the store-and-forward mode, and it is determined to switch the terminal in the RRC connected state to the RRC non-connected state.

[0223] Optionally, the working mode of the network device is the non-store-and-forward mode, and the network device switches the terminal in the RRC connected state to the RRC non-connected state before the working mode is switched to the store-and-forward mode.

[0224] S303B and S302B can be exchanged in order or executed at the same time, and the embodiments of the present disclosure do not make specific limitations thereon.

[0225] In the embodiments of the present disclosure, the working mode of the network device is the non-store-and-forward mode, and the working mode of the network device will be switched to the store-and-forward mode at the time indicated by the time information corresponding to the non-store-and-forward mode. In this case, the network device can switch the terminal that does not support the store-and-forward mode and is in the RRC connected state to the RRC non-connected state before the working mode is switched to the store-and-forward mode, and stop providing network services to guarantee the communication quality.

[0226] In the embodiments of the present disclosure, the working mode of the network device is the non-store-and-forward mode, and the working mode of the network device will be switched to the store-and-forward mode at the time indicated by the time information corresponding to the non-store-and-forward mode. In this case, the network device can switch the terminal that does not support the store-and-forward mode and is in the RRC connected state to the RRC non-connected state before the working mode is switched to the store-and-forward mode, and stop providing network services to guarantee the communication quality.

[0227] It can be understood that the working mode of the network device is a store-and-forward mode, and for a terminal that does not support the capability of the store-and-forward mode, the indication information sent by the network device cannot be recognized, and thus, before the working mode of the network device is switched from the non-store-and-forward mode to the store-and-forward mode, the terminal that does not support the store-and-forward mode and is in the RRC connected state can be converted to the RRC non-connected state, and the network service is stopped to guarantee the communication quality.

[0228] Exemplarily, the indication information sent by the network device indicates that the working mode of the network device is the non-store-and-forward mode, and the time information corresponding to the working mode is the second moment, that is, at the second moment, the working state of the network device will be switched to the store-and-forward mode, and the network device can convert the terminal that does not support the store-and-forward mode and is in the RRC connected state to the RRC non-connected state at the second moment or before the second moment, and stop providing the network service to guarantee the communication quality.

[0229] Exemplarily, if the working mode of the network device is the non-store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the end of the non-store-and-forward mode, or before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode.

[0230] Exemplarily, if the working mode of the network device is the non-store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the time indicated by the time information of the working mode, or before the time indicated by the time information of the working mode, or after the time indicated by the time information of the working mode.

[0231] Exemplarily, the RRC non-connected state includes the RRC idle state and / or the RRC inactive state.

[0232] In some embodiments, the terminal reports the capability information to the network device in the case of being in the RRC connected state, and the capability information indicates whether the terminal supports the capability of the store-and-forward mode.

[0233] In some embodiments, the network device sends a capability reporting request message to the terminal to request the terminal to report the capability information, so that the terminal can report the capability information to the network device in the case of receiving the capability reporting request message sent by the network device, to indicate whether the terminal supports the capability of the store-and-forward mode.

[0234] It should be noted that the terminal can reuse the existing signaling or message to report the capability information to the network device, or can also use a new signaling or message to report the capability information to the network device; the network device can reuse the existing signaling or message to send the reporting request message to the terminal, or can also use a new signaling or message to send the reporting request message to the terminal, and the embodiments of the present disclosure do not make specific limitations in this regard.

[0235] In the embodiments of the present disclosure, the working mode of the network device is a store-and-forward mode. If there is a terminal in the network that does not support the store-and-forward mode and is in an RRC connected state at this time, the network device can convert the terminal that does not support the store-and-forward mode and is in the RRC connected state to an RRC non-connected state, and stop providing network services to guarantee the communication quality.

[0236] In S304B, the network device sets a second parameter waitTimer according to the time information corresponding to the working mode.

[0237] The second parameter waitTimer indicates that the terminal does not support initiating establishment of an RRC connection within the time range indicated by the second parameter waitTimer.

[0238] In the embodiments of the present disclosure, the network device converts the terminal that does not support the store-and-forward mode and is in the RRC connected state to the RRC non-connected state in S303B, and further sets the second parameter waitTimer according to the time information corresponding to the working mode. The time indicated by the second parameter waitTimer is set to be the same as the time indicated by the time information corresponding to the working mode.

[0239] For example, the time indicated by the time information corresponding to the working mode is a second time. In the case where the network device converts the terminal that does not support the store-and-forward mode and is in the RRC connected state to the RRC non-connected state in S303B, the network device sets the second parameter waitTimer to the second time according to the second time indicated by the time information corresponding to the working mode. That is, the terminal does not support initiating establishment of an RRC connection before the second time indicated by the second parameter waitTimer.

[0240] It can be understood that the working mode of the network device is a non-store-and-forward mode. Before the time indicated by the time information corresponding to the non-store-and-forward mode, the working mode of the network device will switch to the store-and-forward mode. When the network device works in the store-and-forward mode, the network device has no connection with the ground node and / or the terminal, and will store data and transmit the data after the connection is restored. Therefore, before this time, the network device can convert the terminal in the RRC connected state to the RRC non-connected state to avoid the terminal transmitting data to the network device and to avoid data transmission delay and guarantee the communication quality. In addition, the network device sets the second parameter waitTimer to be the same as the time indicated by the time information corresponding to the non-store-and-forward mode, which can further indicate the terminal not to establish an RRC connection and not to perform data transmission before the time indicated by the time information corresponding to the non-store-and-forward mode, so as to avoid data transmission delay and guarantee the communication quality.

[0241] Exemplarily, if the working mode of the network device is the non- store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the end of the non-store-and-forward mode, or before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode, and further, the network device can set the second parameter waitTimer according to the time information corresponding to the working mode. Wherein, the second parameter waitTimer is set to be the same as the time indicated by the time information of the working mode, for example, the time information corresponding to the working mode is the first time, and the network device sets the time range indicated by the second parameter waitTimer to be before the first time.

[0242] Exemplarily, if the working mode of the network device is the non- store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the end of the non-store-and-forward mode, or before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode, and further, the network device can set the second parameter waitTimer according to the time information corresponding to the working mode. Wherein, the second parameter waitTimer is set to be the same as the time indicated by the time information of the working mode, for example, the time information corresponding to the working mode is the first time, and the network device sets the time range indicated by the second parameter waitTimer to be before the first time.

[0243] Optionally, the working mode of the network device is the store-and-forward mode, and if there is a terminal in the RRC connected state in the network, the network device can convert the terminal in the RRC connected state to the RRC non-connected state.

[0244] Optionally, the working mode of the network device is the store-and-forward mode, and the network device sets the second parameter waitTimer according to the time information corresponding to the store-and-forward mode. The beneficial effects are similar to those of the network device setting the second parameter waitTimer according to the time information corresponding to the non-store-and-forward mode, which will not be repeated here.

[0245] S305B, the network device sends the second parameter waitTimer to the terminal.

[0246] In the embodiment of the present disclosure, the network device sends the second parameter waitTimer to the terminal by itself, or sends the second parameter waitTimer to the terminal based on a protocol agreement, or sends the second parameter waitTimer to the terminal based on the request of the terminal, and the present embodiment does not make specific limitation.

[0247] In the embodiment of the present disclosure, the network device sends the second parameter waitTimer to the terminal after setting the second parameter waitTimer according to S304B.

[0248] In some embodiments, the terminal receives the second parameter waitTimer sent by the network device, and can determine not to initiate the process of establishing the RRC connection within the time range indicated by the second parameter, which can reduce communication overhead.

[0249] For example, if the working mode of the network device is the non- store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the end of the non-store-and-forward mode, or before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode, and further, the network device can set the second parameter waitTimer according to the time information corresponding to the working mode. Wherein, the second parameter waitTimer is set to be the same as the time indicated by the time information of the working mode, for example, the time information corresponding to the working mode is the first time, and the network device sets the time range indicated by the second parameter waitTimer to be before the first time. Then, the network device sends the second parameter waitTimer to the terminal, and the terminal can determine not to initiate the process of establishing the RRC connection within the time range indicated by the second parameter waitTimer, which can reduce communication overhead, save terminal power, save resources, and guarantee communication quality.

[0250] For example, if the working mode of the network device is the non- store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the end of the non-store-and-forward mode, or before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode, and further, the network device can set the second parameter waitTimer according to the time information corresponding to the working mode. Wherein, the second parameter waitTimer is set to be the same as the time indicated by the time information of the working mode, for example, the time information corresponding to the working mode is the first time, and the network device sets the time range indicated by the second parameter waitTimer to be before the first time. Then, the network device sends the second parameter waitTimer to the terminal, and the terminal can determine not to initiate the process of establishing the RRC connection within the time range indicated by the second parameter waitTimer, which can reduce communication overhead, save terminal power, save resources, and guarantee communication quality.

[0251] S306B, the network device sends an RRC release message to the terminal.

[0252] Wherein, the RRC release message carries a cause value, and the cause value is information related to the store-and-forward mode.

[0253] S306B and S305B can exchange order or be executed at the same time, S306B and S304B can exchange order or be executed at the same time, and the embodiments of the present disclosure do not make specific restrictions.

[0254] In the embodiments of the present disclosure, the network device can send an RRC release message to the terminal in the RRC connected state to release the RRC connection between the network device and the terminal, so as to guarantee the communication quality.

[0255] In the embodiments of the present disclosure, the RRC release message sent by the network device carries a cause value, and the cause value is information related to the store-and-forward mode, so that the terminal receiving the RRC release message sent by the network device can determine that the reason for the disconnection of the RRC connection is related to the working mode of the network device.

[0256] For example, the cause value can indicate that the network device works in the store-and-forward mode.

[0257] For example, if the working mode of the network device is the non-store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the end of the non-store-and-forward mode, or before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode, wherein the network device can send an RRC release message to the terminal, and the RRC release message carries a cause value, and the cause value is information related to the store-and-forward mode, for example, the cause value can indicate that the working mode of the network device is the store-and-forward mode. Therefore, the terminal can determine that the reason for the network to disconnect the RRC is related to the working mode of the network device.

[0258] For example, if the working mode of the network device is the non-store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the time indicated by the time information of the working mode, or before the time indicated by the time information of the working mode, or after the time indicated by the time information of the working mode, wherein the network device can send an RRC release message to the terminal, and the RRC release message carries a cause value, and the cause value is information related to the store-and-forward mode, for example, the cause value can indicate that the working mode of the network device is the store-and-forward mode. Therefore, the terminal can determine that the reason for the network to disconnect the RRC is related to the working mode of the network device.

[0259] In some embodiments, the second parameter waitTimer is included in the RRC release message sent by the network device.

[0260] For example, if the working mode of the network device is the non- store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the end of the non-store-and-forward mode, before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode. The network device can send an RRC release message to the terminal, and the RRC release message carries a cause value and can also indicate a second parameter waitTimer. The cause value is information related to the store-and-forward mode, for example, the cause value can indicate that the working mode of the network device is the store-and-forward mode. Therefore, the terminal can determine that the reason for the network to disconnect the RRC is related to the working mode of the network device, and the terminal does not initiate the process of establishing the RRC connection within the time range indicated by the second parameter waitTimer, which can reduce the communication overhead, save the terminal power, save resources, and ensure the communication quality.

[0261] For example, if the working mode of the network device is the non- store-and-forward mode, the network device converts the terminal in the RRC connected state to the RRC non-connected state at the end of the non-store-and-forward mode, before the end of the non-store-and-forward mode, or after the end of the non-store-and-forward mode. The network device can send an RRC release message to the terminal, and the RRC release message carries a cause value and can also indicate a second parameter waitTimer. The cause value is information related to the store-and-forward mode, for example, the cause value can indicate that the working mode of the network device is the store-and-forward mode. Therefore, the terminal can determine that the reason for the network to disconnect the RRC is related to the working mode of the network device, and the terminal does not initiate the process of establishing the RRC connection within the time range indicated by the second parameter waitTimer, which can reduce the communication overhead, save the terminal power, save resources, and ensure the communication quality.

[0262] By implementing the embodiments of the present disclosure, the network device can send indication information to the terminal to indicate the working mode information for data transmission, so that the terminal can perform a communication process matched with the working mode information of the network device according to the working mode information indicated by the network device, and ensure the communication quality.

[0275] Figure 3C is an interaction diagram of an information indication method according to an embodiment of the present disclosure. As shown in Figure 3C, the embodiment of the present disclosure relates to an information indication method, and the above method comprises:

[0276] S301C, the network device sends indication information to the terminal.

[0277] The indication information is used to indicate at least one of the following information of the network device for data transmission: working mode; time information corresponding to the working mode; wherein the working mode is a store-and-forward mode or a non-store-and-forward mode.

[0278] The optional implementation of S301C can be found in the optional implementation of S301A of Figure 3A and other related parts in the embodiments involved by Figure 3A, which will not be repeated here.

[0279] In some embodiments, the network device sends indication information to the terminal, comprising: sending a system information block (SIB) to the terminal, wherein the SIB comprises the indication information.

[0280] The working mode information is used to indicate at least one of the following: the working mode is a store-and-forward mode; the working mode is a non-store-and-forward mode; and time information corresponding to the working mode.

[0281] In some embodiments, the time information corresponding to the working mode is used to indicate an end time corresponding to the working mode, or a duration corresponding to the working mode, or a switching time corresponding to the working mode.

[0282] It can be understood that different terminals can have different behaviors in different working modes of the network device. For example, consider the following several different types of terminals: a legacy terminal: a terminal before version 19, which does not support the capability of the store-and-forward mode and cannot recognize the indication information provided by the network device to indicate the working mode information of the network device for data transmission; a terminal of version 19 but not supporting the capability of the store-and-forward mode; a terminal of version 19 and later versions, supporting the capability of the store-and-forward mode and being able to recognize the indication information provided by the network device to indicate the working mode information of the network device for data transmission.

[0283] S302C, the terminal is in an RRC non-connected state, the working mode of the network device is a non-store-and-forward mode, and the terminal performs cell reselection before the network device switches to the store-and-forward mode according to the time information corresponding to the non-store-and-forward mode.

[0284] Optionally, the terminal is in an RRC non-connected state, the working mode of the network device is a non-store-and-forward mode, and the terminal performs cell reselection before the network device switches to the store-and-forward mode.

[0285] In the embodiments of the present disclosure, the terminal receives the indication information sent by the network device. In the case that the indication information indicates that the working mode of the network device is a non-store-and-forward mode and the time information corresponding to the working mode indicates that the working mode of the network device will be switched from the non-store-and-forward mode to the store-and-forward mode, if the terminal is in an RRC non-connected state and does not support the store-and-forward mode, the terminal can determine to perform cell reselection before the network device switches to the store-and-forward mode, to measure (perform frequency measurement) the serving cell and / or the neighbor cell, and select to access a cell with a non-store-and-forward mode, so as to guarantee the communication quality.

[0286] Exemplarily, the terminal receives indication information sent by the network device, where the indication information is used to indicate that the working mode of the network device is the non- store-and-forward mode, and the time information corresponding to the working mode indicates that the working mode of the network device will switch to the store-and-forward mode or the non- store-and-forward mode will end at the first time. In this case, the terminal is in the RRC non-connected state and does not support the store-and-forward mode. The terminal can perform cell reselection at or before the first time, where the cell reselection includes neighbor cell measurement and / or determining a target cell, and the communication quality can be guaranteed.

[0287] In S303C, the network device is in the store-and-forward mode, and the terminal in the RRC connected state is switched to a cell in the non-store-and-forward mode; or the network device is in the non-store-and-forward mode, and the network device switches the terminal in the RRC connected state to another cell in the non-store-and-forward mode according to the time information corresponding to the working mode before the working mode switches to the store-and-forward mode.

[0290] In the embodiments of the present disclosure, the network device is in the store-and-forward mode. If there is a terminal in the RRC connected state and not supporting the store-and-forward mode in the network, the network device can switch the terminal in the RRC connected state and not supporting the store-and-forward mode to a cell in the non-store-and-forward mode, so as to accurately provide network services for the terminal and guarantee the communication quality.

[0291] In the embodiments of the present disclosure, the network device is in the non-store-and-forward mode, and the network device switches the terminal in the RRC connected state to another cell in the non-store-and-forward mode according to the time information corresponding to the working mode before the working mode switches to the store-and-forward mode.

[0293] In S304C, the working mode of the network device is the non-Store-and-Forward mode, and the terminal determines whether to access the to-be-accessed cell according to a third parameter of the to-be-accessed cell, where the third parameter of the to-be-accessed cell is used to indicate whether the terminal is supported to access; or the working mode of the network device is the Store-and-Forward mode, and if the terminal supports the Store-and-Forward mode, the terminal ignores the third parameter of the to-be-accessed cell, where the third parameter of the to-be-accessed cell is used to indicate whether the terminal is supported to access.

[0294] S304C and S303C can exchange orders or be executed at the same time, and S304C and S302C can exchange orders or be executed at the same time, and the embodiments of the present disclosure do not make specific limitations on this.

[0295] In some embodiments, the third parameter is cellBarred-NTN, if the third parameter is set as barred, it indicates that the terminal is not supported to access, and if the third parameter is set as not barred, it indicates that the terminal is supported to access.

[0296] In the embodiments of the present disclosure, the working mode of the network device is the non-Store-and-Forward mode, and the network device does not support data storage, that is, without connection with the terminal or the ground node, the network device cannot pre-store data and send corresponding data after the connection is established, in this case, the terminal determines whether to access the to-be-accessed cell according to a third parameter of the to-be-accessed cell, where the third parameter of the to-be-accessed cell is used to indicate whether the terminal is supported to access; where in the case that the third parameter of the to-be-accessed cell indicates that the terminal is supported to access, the terminal accesses the to-be-accessed cell, and in the case that the third parameter of the to-be-accessed cell indicates that the terminal is not supported to access, the terminal can not access the to-be-accessed cell, thereby guaranteeing the communication quality.

[0297] In the embodiments of the present disclosure, the working mode of the network device is a store-and-forward mode, the network device supports data storage, that is, in the case that there is no connection with the terminal or the ground node, the data can be stored in advance, and the corresponding data is sent after the connection is established. In this case, if the terminal supports the store-and-forward mode, the terminal ignores the third parameter of the cell to be accessed, that is, regardless of whether the third parameter of the cell to be accessed indicates that the terminal is supported to access or not supported to access, the terminal can access the cell to be accessed according to the access. If the terminal does not support the store-and-forward mode, the terminal determines whether the cell can be accessed according to the third parameter.

[0478] In some embodiments, the working mode information of the network device is provided by the system message, and the change of the working mode information of the network device does not cause the change of the system message update notification and the value tag.

[0479] In some embodiments, the UE should reacquire the system message according to the time information corresponding to the working mode.

[0480] In some embodiments, when the network device works in the normal mode and provides the time information of the normal mode:

[0481] The network sets the value of t-service to the same value as the time information, and the UE without S&F function performs cell reselection according to t-service;

[0482] If the UE supports the S&F mode, the t-service is ignored, or the UE does not perform cell reselection according to t-service;

[0483] If the UE supports the S&F mode, it is determined whether the cell can be accessed according to cellBarred-NTN;

[0484] The UE in RRC connected state which does not support S&F mode and is in RRC connected state at the time indicated by the time information will be transitioned to RRC idle state.

[0485] In some embodiments, when the network device works in S&F mode, and provides time information of S&F mode:

[0489] Normal mode;

[0490] Normal mode and time of normal mode;

[0494] Store and forward mode on indicates that the network works in store and forward mode;

[0495] Store and forward mode off indicates that the network works in normal mode;

[0496] Store and forward mode present indicates that the network works in store and forward mode;

[0497] Store and forward mode absent indicates that the network works in normal mode.

[0506] In some embodiments, when the working mode of the network device is the normal working mode, the network device sets the value of t-service to the same value as the time information.

[0507] In some embodiments, when the working mode of the network device is the normal working mode, if the UE does not support the S&F mode, the cell reselection (neighbor cell measurement) is performed according to t-service; if the UE supports the S&F mode, the t-service is ignored, or the UE does not perform the cell reselection (neighbor cell measurement) according to t-service.

[0508] In some embodiments, when the working mode of the network device is the normal working mode, the network device converts the RRC connected state UE that does not support the S&F capability to the RRC non-connected state at the time or before the time.

[0509] In some embodiments, when the working mode of the network device is the normal working mode, if the UE supports S&F, the UE starts the S&F function at the time; or if the UE does not support S&F but can acquire the mode information, the RRC connected state determines to enter the RRC idle state at the time, and if it is the RRC non-connected state UE, the cell reselection (neighbor cell measurement) is performed before the time; if the time cannot satisfy the RRC non-connected state UE to perform the RRC connection establishment, the RRC connection reestablishment, and the RRC connection recovery in the cell, the UE does not perform these processes.

[0510] In some embodiments, when the network device works in the normal mode, the UE that does not support the S&F capability determines whether to access the cell according to the cellBarred-NTN; if the cellBarred-NTN is set to barred, the UE cannot access the cell of the NTN; if the cellBarred-NTN is set to not barred, the UE can access the cell of the NTN.

[0511] In some embodiments, when the network device works in the S&F mode, if there is a UE that does not support the S&F capability in the network, the network device can convert the RRC connected UE to the RRC non-connected state, or switch the RRC connected UE to the cell in the normal mode.

[0512] In some embodiments, when the RRC connected UE is converted to the RRC non-connected state, the time of the wait timer is set according to the time of the S&F mode; for example, the time length of the wait timer is the same as the time.

[0513] In some embodiments, the value cause in the RRC release message is set to the S&F mode related information.

[0514] In some embodiments, if the UE supports the S&F, the UE ignores the cellBarred-NTN.

[0515] In some embodiments, when the network device works in the S&F mode, the UE is converted to the normal mode when the time is reached, or the time is expired.
