[0109] First, based on the technical solution provided in this application, some technical terms that may be involved are introduced.

[0110] 1. Scenarios where data needs to be stored and forwarded on satellites

[0111] For some research institutions, it is necessary to study the living habits and movement trajectories of animals; for government departments, it is necessary to give timely warnings to reduce or avoid the occurrence of disasters, such as the detection of submarine cables; these Internet of Things (IoT) deployed on animals or equipment are located in special or remote areas, where there are no communication base stations, so data transmission is required through satellite communications. Since they do not have high requirements for latency, these places may not have the deployment of gateway stations, so the data can be uploaded to the satellite first, stored on the satellite (there may be base stations or core network elements on the satellite), and then forwarded when the satellite can access the gateway station.

[0112] In order to support the above scenarios, base stations or some core network elements need to be deployed on satellites. The data from terminals or ships can be transmitted back to local gateways to the core network via satellites, or transmitted back to distant gateways to the core network via intersatellite links.

[0113] Method for supporting terminals to use on-board base stations / on-board store-and-forward services, so that terminal users can use on-board services for communication:

[0114] 1. Method and process for UE to negotiate parameters with AMF or Radio Access Network (RAN);

[0115] UE side: The UE sends an on-board store-and-forward request to the RAN. The request may optionally include one or a combination of the above parameters, including the data validity period supported by the terminal, the transmission time window, the data failure processing method (such as retransmission or discard), and the data transmission method negotiation (such as using UP (PDU) or small data).

[0116] RAN side: RAN receives the request information sent by UE and forwards it to AMF; based on the obtained parameters, it confirms the negotiation result of the parameters.

[0117] AMF side: AMF receives the request information sent by UE forwarded by RAN, obtains authentication information from UDM, and confirms that it supports the request; based on the obtained parameters, it confirms the negotiation result of the parameters

[0118] 2. During the PDU session, the SMF confirms the negotiation results of the parameters based on the obtained parameters;

[0119] 3. Base station authentication.

[0120] Currently, there is no negotiation mechanism for satellites and satellite network elements to allocate the full store-and-forward capacity requested by UEs.

[0121] Based on the analysis, the embodiments of the present application provide an information transmission method, apparatus, terminal and network device to solve the problem of how to satisfy the UE's storage forwarding request to the greatest extent when the entire storage space requested by the UE cannot be allocated to the current UE.

[0122] 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.

[0123] like Figure 2 As shown, an embodiment of the present application provides an information transmission method, which is executed by a network device, including:

[0124] Step S201, judging whether the satellite storage and forwarding device can meet the storage and forwarding requirements of the terminal according to the first information;

[0125] The first information includes at least one of the following: the storage and forwarding capacity requested by the terminal, the indication information of whether the terminal supports segmented transmission, the minimum value of the storage and forwarding capacity that the terminal can accept to be allocated to it, and the maximum storage and forwarding capacity that the satellite storage and forwarding device can allocate to the terminal for providing storage and forwarding services;

[0126] It should be noted that the indication information is usually used to indicate whether the terminal supports sending data in segments to the satellite storage and forwarding device.

[0127] The satellite storage and forwarding device mentioned in the embodiments of the present application generally refers to a storage and forwarding device installed on a satellite (also referred to as an on-board storage and forwarding device). The network device mentioned in the embodiments of the present application may be installed together with the satellite storage and forwarding device, or the two may be installed independently.

[0128] Step S202: Send second information to the terminal according to the judgment result, where the second information is used to indicate a time point when the terminal sends a store-and-forward request next time.

[0129] Optionally, the network device of the embodiment of the present application refers to an access and mobility management function (Access and Mobility Management Function, AMF), or a session management function (Session Management Function, SMF), or an access network node (for example, a base station).

[0130] Optionally, in one implementation, judging, based on the first information, whether the satellite storage and forwarding device can meet the storage and forwarding requirements of the terminal includes at least one of the following storage and forwarding capacities:

[0131] A11, if the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, determining that the satellite storage and forwarding device cannot meet the storage and forwarding requirements of the terminal;

[0132] It should be noted that if the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, it means that the storage and forwarding capacity that the satellite storage and forwarding device can allocate to the terminal cannot meet the terminal's needs, and it is determined that the satellite storage and forwarding device cannot meet the terminal's storage and forwarding needs.

[0133] A12, if the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal does not support segmented transmission, determining that the satellite storage and forwarding device cannot meet the storage and forwarding requirements of the terminal;

[0134] It should be noted that if the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity and the terminal does not support segmented transmission, it means that the storage and forwarding capacity that the satellite storage and forwarding device can allocate to the terminal cannot meet the needs of the terminal, and it is determined that the satellite storage and forwarding device cannot meet the storage and forwarding needs of the terminal.

[0135] A13, when the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal supports segmented transmission, if the minimum value of the storage and forwarding capacity allocated to the terminal that the terminal can accept is greater than the maximum storage and forwarding capacity, determining that the satellite storage and forwarding device cannot meet the storage and forwarding demand of the terminal;

[0136] A14, when the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal supports segmented transmission, if the minimum value of the storage and forwarding capacity allocated to the terminal that the terminal can accept is less than or equal to the maximum storage and forwarding capacity, determining that the satellite storage and forwarding device can meet the storage and forwarding requirements of the terminal;

[0137] It should be noted that if the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity and the terminal supports segmented transmission, it is necessary to determine the relationship between the minimum value of the storage and forwarding capacity allocated to it that the terminal can accept and the maximum storage and forwarding capacity. If the minimum value of the storage and forwarding capacity allocated to it that the terminal can accept is greater than the maximum storage and forwarding capacity, it means that in the case of segmented transmission, the maximum storage and forwarding capacity does not meet the minimum requirements of the terminal for segmented transmission, that is, the storage and forwarding capacity that the satellite storage and forwarding device can allocate to the terminal cannot meet the needs of the terminal, and it is determined that the satellite storage and forwarding device cannot meet the storage and forwarding needs of the terminal; if the minimum value of the storage and forwarding capacity allocated to it that the terminal can accept is less than or equal to the maximum storage and forwarding capacity, it means that in the case of segmented transmission, the maximum storage and forwarding capacity can meet the minimum requirements of the terminal for segmented transmission, that is, the storage and forwarding capacity that the satellite storage and forwarding device can allocate to the terminal can meet the needs of the terminal, and it is determined that the satellite storage and forwarding device can meet the storage and forwarding needs of the terminal.

[0138] A15, if the storage and forwarding capacity requested by the terminal is less than or equal to the maximum storage and forwarding capacity, determining that the satellite storage and forwarding device can meet the storage and forwarding requirements of the terminal;

[0139] It should be noted that if the storage and forwarding capacity requested by the terminal is less than or equal to the maximum storage and forwarding capacity, it means that the storage and forwarding capacity that the satellite storage and forwarding device can allocate to the terminal can meet the needs of the terminal, and it is determined that the satellite storage and forwarding device can meet the storage and forwarding needs of the terminal.

[0140] It should be further explained that, in the case where the satellite storage and forwarding device cannot meet the storage and forwarding needs of the terminal and needs to be sent in segments, the network device needs to inform the terminal of the time point at which the storage and forwarding capacity occupied by the remaining unallocated storage space data of the terminal can be met. Optionally, the network device can determine when the terminal can continue to initiate a storage and forwarding request (also called a secondary storage and forwarding request) for the remaining unallocated storage space data based on the storage and forwarding capacity of the satellite storage and forwarding device, the occupied storage and forwarding capacity, and the data expiration time of other terminals, that is, the time point at which the storage and forwarding capacity occupied by the remaining unallocated storage space data of the terminal can be met. In the case where the satellite storage and forwarding device cannot meet the storage and forwarding needs of the terminal, the network device needs to decide the time point at which the terminal can re-request the storage and forwarding capacity based on the usage of the satellite storage and forwarding device.

[0141] Optionally, in one implementation, the time point at which the terminal sends a store-and-forward request next time includes at least one of the following:

[0142] A21, a time point at which the terminal can re-request the storage and forwarding capacity;

[0143] It should be noted that, when the satellite storage and forwarding device cannot meet the storage and forwarding requirements of the terminal, the network device should feed back to the terminal a time point at which the terminal can re-request storage and forwarding capacity.

[0144] A22, a time point at which the storage and forwarding capacity occupied by the remaining unallocated storage space data of the terminal can be satisfied;

[0145] It should be noted that when the satellite storage and forwarding device can meet the storage and forwarding needs of the terminal, but the network device cannot provide the terminal with all the storage and forwarding capacity it requests, the network device should feedback to the terminal the time point when the storage and forwarding capacity occupied by the remaining unallocated storage space data of the terminal can be met.

[0146] Optionally, in one implementation, the second information is further used to indicate at least one of the following:

[0147] A31, the reason for rejecting the requested store-and-forward capacity;

[0148] It should be noted that if the satellite storage and forwarding device cannot meet the storage and forwarding requirements of the terminal, it is necessary to feedback to the terminal to reject the storage and forwarding request of the terminal, and the rejection reason may be insufficient current storage and forwarding capacity.

[0149] A32. Reasons for segmented allocation of capacity for storage and forwarding data;

[0150] It should be noted that if the satellite storage and forwarding equipment can meet the storage and forwarding requirements of the terminal, it is necessary to feedback the reason for the segment allocation to the terminal. The reason may be that the maximum storage and forwarding capacity that can be allocated to the terminal for providing storage and forwarding services is greater than or equal to the minimum value of the storage and forwarding capacity that the terminal can accept allocated to it.

[0151] Optionally, when the terminal receives the second information fed back by the network device and determines to accept the segmented allocation of capacity for storage and forwarding data, it sends a storage and forwarding request to the network device after the time point indicated by the second information that can satisfy the storage and forwarding capacity occupied by the remaining unallocated storage space data of the terminal. The storage and forwarding request sent in this case can be called a secondary storage and forwarding request.

[0152] Optionally, when the terminal receives the second information fed back by the network device and determines that the satellite storage and forwarding device cannot meet the storage and forwarding requirements of the terminal, the terminal resends the storage and forwarding request to the network device after the time point indicated by the second information that can satisfy the terminal's re-request for storage and forwarding capacity.

[0153] Optionally, in one implementation, the storage and forwarding capacity is sent by the terminal to the network device. The indication information of whether the terminal supports segmented transmission may be sent by the terminal to the network device, or obtained through a core network element. The minimum value of the storage and forwarding capacity that the terminal can accept to be allocated to it may be sent by the terminal to the network device, or obtained through a core network element.

[0154] Optionally, in one implementation, the implementation of obtaining the maximum store-and-forward capacity includes:

[0155] Determining the maximum store-and-forward capacity according to the third information;

[0156] Among them, the third information includes at least one of the following items: the capacity of the terminal storage and forwarding request (which can also be understood as the storage and forwarding capacity requested by the terminal), the requested data storage time, and the remaining unoccupied storage and forwarding capacity of the satellite storage and forwarding device (which can also be understood as the remaining unused storage and forwarding capacity of the satellite storage and forwarding device corresponding to the moment when the terminal requests the storage and forwarding capacity).

[0157] Optionally, the core network element may be a UDM or an AMF.

[0158] It should be noted that the application architecture of the embodiments of the present application mainly includes the following two types:

[0159] Application Architecture 1. Figure 3 As shown, a lightweight 5G core network (5GC) and an access network (e.g., base station) are deployed on the same satellite; the 5GC may include at least one of the following: AMF, SMF, unified data management (UDM), and user plane function (UPF).

[0160] Application Architecture II Figure 4 As shown, the access network and UPF are deployed in low-orbit satellites, and lightweight 5GC (for example, including at least one of the following: AMF, SMF, UDM) is deployed in high-orbit satellites.

[0161] It should be noted that in these two application architectures, UDM stores contract information, and data is temporarily stored in UPF, or additional storage devices are installed together with it.

[0162] It should be noted here that the two architectures have the same solution for activating the store-and-forward mechanism and PDU transmission.

[0163] The specific application process of the embodiment of the present application is illustrated below by way of example.

[0164] Application Scenario 1: AMF determines whether the storage and forwarding device can meet the storage and forwarding capacity requested by the terminal

[0165] like Figure 5 As shown in the figure, the specific implementation process includes:

[0166] Step 501: During the registration request process, the terminal, in addition to the relevant parameters of the on-board storage and forwarding service request, carries the requested storage and forwarding capacity and indication information of whether the terminal supports segmented transmission; optionally, it may also carry the minimum value of the storage and forwarding capacity that the terminal can accept to be allocated to it (i.e., the lower limit of the storage and forwarding capacity that the terminal can accept and that is allocated to it by the network).

[0167] Step 502: The onboard access network node forwards the registration request to the AMF.

[0168] Step 503: AMF obtains the terminal's subscription information about the on-board store-and-forward service from UDM.

[0169] Optionally, the subscription information may include a lower limit of the storage and forwarding capacity allocated to the terminal by the network that the terminal can accept.

[0170] It should be noted that if the registration request of the terminal in step 501 does not carry the lower limit of the storage and forwarding capacity allocated by the network to the terminal that the terminal can accept, the information can also be obtained from the subscription data of the terminal.

[0171] Step 504: AMF obtains ephemeris information.

[0172] Step 505: AMF decides whether the store-and-forward request of the terminal can be satisfied;

[0173] Optionally, in one case, if the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal does not support segmented transmission, then AMF decides that the storage and forwarding request of the terminal cannot be met at present, and AMF decides the time point at which the terminal can re-request the storage and forwarding capacity based on the usage of the storage and forwarding device, i.e., the backoff time point, as well as result information such as the current rejection reason (such as insufficient current capacity).

[0174] Optionally, in another case, when the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal supports segmented sending, if the terminal can accept that the minimum storage and forwarding capacity allocated to it is less than or equal to the maximum storage and forwarding capacity, AMF again makes a comprehensive decision based on the storage and forwarding capacity of the storage and forwarding device, the occupied storage and forwarding capacity, and the data expiration time of other terminals to determine the time point at which the storage and forwarding capacity occupied by the remaining unallocated storage space data of the terminal can be satisfied, i.e., the backoff time point.

[0175] It should be noted that in this application, the storage and forwarding device is AMF, and can also be SMF, UDM and other NFs or RAN or on-board storage and forwarding devices jointly set up with NF / RAN, which depends on the actual deployment. If the storage device is a NF other than AMF, interaction with this NF is added after the above step 504 to obtain information related to the storage and forwarding device such as the current storage and forwarding capacity of the storage and forwarding device, and the same is true for RAN.

[0176] Step 506: The AMF returns a registration response to the terminal through the onboard access network node, where the response includes the backoff time point described in step 505 above.

[0177] Optionally, the reason for rejecting the requested store-and-forward capacity or the reason for the segmented allocation of capacity for store-and-forward data may be included.

[0178] Step 507: The terminal decides whether to accept segmented capacity allocation for storing and forwarding data.

[0179] Step 508: If the segmented allocation of storage and forwarding data capacity is accepted, the terminal will initiate a secondary storage and forwarding request for the remaining unallocated storage space data again after the backoff time.

[0180] It should be noted that in step 508, the terminal may send a secondary store-and-forward request to the network via one of the following messages:

[0181] Existing NAS messages (such as mobility registration update, the store-and-forward device is AMF);

[0182] Newly defined message.

[0183] It should be noted that step 507 and step 508 are performed only when a registration response indicating the reason for segmented allocation of capacity for storage and forwarding data is received.

[0184] Application Scenario 2: SMF determines whether the storage and forwarding device can meet the storage and forwarding capacity requested by the terminal

[0185] like Figure 6 As shown in the figure, the specific implementation process includes:

[0186] Step 601: The terminal initiates a PDU session request to the onboard access network node. The request message carries the requested storage and forwarding capacity, the minimum storage and forwarding capacity that the terminal can accept allocated to it under the current session (i.e., the lower limit of the storage and forwarding capacity allocated to it by the network that the terminal can accept); optionally, it can also carry indication information on whether the terminal supports segmented transmission.

[0187] Step 602: The onboard access network node forwards the PDU session request to the AMF.

[0188] Step 603: AMF sends a PDU session context establishment request to SMF. The request message carries the requested storage and forwarding capacity, as well as the lower limit of the storage and forwarding capacity allocated to it by the network that the terminal can accept under the current session. Optionally, it can also carry an indication of whether the terminal supports segmented transmission.

[0189] Step 604: SMF obtains contract information from UDM.

[0190] Optionally, if the PDU session request does not carry the indication information of whether the terminal supports segmented sending, the information needs to be obtained from the contract information returned by the UDM.

[0191] Step 605: SMF returns a PDU session context establishment response to AMF.

[0192] Step 606: SMF obtains ephemeris information.

[0193] Step 607: SMF decides whether to accept the store-and-forward request of the current session based on the received information.

[0194] Optionally, in one case, if the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal does not support segmented sending, the SMF decides that the storage and forwarding request for the service corresponding to the terminal's session cannot be met at present, and the SMF decides the time point when the terminal's re-request can be met based on the usage of the storage and forwarding device, i.e., the backoff time point, as well as result information such as the current rejection reason (such as insufficient current capacity).

[0195] Optionally, in another case, when the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal supports segmented transmission, if the terminal can accept that the minimum storage and forwarding capacity allocated to it is less than or equal to the maximum storage and forwarding capacity, SMF again makes a comprehensive decision based on the storage and forwarding capacity of the storage and forwarding device, the occupied storage and forwarding capacity, and the data expiration time of other terminals to determine the time point at which the storage and forwarding capacity occupied by the remaining unallocated storage space data of the terminal can be satisfied, i.e., the backoff time point.

[0196] Step 608: SMF sends a Namf_Communication_N1N2MessageTransfer to AMF, carrying the backoff time and, optionally, indicating the reason for the terminal segmentation request or the reason for rejecting the requested storage and forwarding capacity.

[0197] Step 609: AMF sends a PDU session request response to the terminal through the access network node;

[0198] The PDU session request response carries the backoff time determined in step 608 and optionally indicates the reason for the terminal session segmentation request or the reason for rejecting the requested store-and-forward capacity.

[0199] Step 610: The terminal decides whether to allocate the capacity for storing and forwarding data in segments.

[0200] Step 611: If the segmented capacity allocation of the storage and forwarding data is accepted, the terminal will initiate a secondary storage and forwarding request for the remaining unallocated storage space data again after the backoff time. The request process can be implemented by PDU session modification, new PDU session establishment or newly defined messages.

[0201] It should be noted that step 610 and step 611 are performed only when a PDU session request response is received indicating the reason for segmented allocation of capacity for storage and forwarding data.

[0202] Application Scenario 3: RAN decides whether the store-and-forward device can meet the store-and-forward capacity requested by the terminal

[0203] like Figure 7 As shown in the figure, the specific implementation process includes:

[0204] Step 701 is the same as step 501 in application scenario 1.

[0205] Step 702: The satellite access network node sends a registration request to the network, carrying a store-and-forward service request.

[0206] Step 703 is the same as step 503 in application scenario 1.

[0207] Step 704: AMF determines whether the network side allows the store-and-forward service of this terminal based on the contract data.

[0208] Step 705: If the store-and-forward service of the terminal is allowed, a registration reception response is sent to the on-board access network node;

[0209] Optionally, the registration reception response carries indication information in the subscription data as to whether the terminal supports segmented transmission.

[0210] Step 706: The onboard access network node decides whether the store-and-forward request of the terminal can be satisfied.

[0211] Optionally, in one case, if the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal does not support segmented transmission, the onboard access network node decides that the storage and forwarding request of the terminal cannot be met at present, and the onboard access network node decides the time point when the terminal can re-request the storage and forwarding capacity based on the usage of the storage and forwarding device, i.e., the backoff time point, as well as result information such as the current rejection reason (such as insufficient current capacity).

[0212] Optionally, in another case, when the storage and forwarding capacity requested by the terminal is greater than the maximum storage and forwarding capacity, and the indication information indicates that the terminal supports segmented transmission, if the terminal can accept that the minimum storage and forwarding capacity allocated to it is less than or equal to the maximum storage and forwarding capacity, the onboard access network node will again store and forward the storage and forwarding capacity of the device, the occupied storage and forwarding capacity, and the data expiration time of other terminals, and comprehensively consider the time point at which the storage and forwarding capacity occupied by the remaining unallocated storage space data of the terminal can be satisfied, i.e., the backoff time point.

[0213] Step 707: The on-board access network node sends a registration response to the terminal, where the registration response carries the backoff time decided by the on-board access network node.

[0214] Optionally, the registration response may also carry a reason for segmented allocation of the storage and forwarding data capacity or a reason for rejecting the requested storage and forwarding capacity.

[0215] Step 708: The terminal decides whether to accept segmented capacity allocation for storing and forwarding data.

[0216] Step 709: If the segmented capacity allocation of the storage and forwarding data is accepted, the terminal will initiate a secondary storage and forwarding request for the remaining unallocated storage space data again after the backoff time. The secondary storage and forwarding request can be implemented through RRC configuration update or newly defined message and other processes.

[0217] It should be noted that step 708 and step 709 are performed only when a registration response indicating the reason for segmented allocation of capacity for storage and forwarding data is received.

[0218] In summary, the embodiments of the present application solve the problem of how to efficiently utilize the storage and forwarding space when the on-board storage and forwarding service capacity requested by the terminal is greater than the storage and forwarding capacity that the on-board storage and forwarding device can provide for the current terminal, thereby improving the resource utilization of the on-board storage and forwarding device.
