Description

Technical Field

[0001] The present application relates to the field of satellite communication technology, and in particular to an information transmission method, device, terminal and network equipment. Background Art

[0002] In the on-board storage and forwarding scenario, the on-board storage device will allocate a storage space of a specific capacity (also called storage and forwarding space) to the user equipment (UE) for data storage according to its request. Usually, the storage space of the specific capacity is valid for a specific time, which is generally the longest valid time of the storage space serving the UE. When the specific time allocated to the UE expires, the storage space of the specific capacity will be released. It should also be noted here that if the on-board storage device cannot allocate storage space for the newly applied UE, it will affect the storage service provided to the UE.

[0003] In actual operation, when the satellite device restores the link with the ground device, the data stored in the on-board storage device is forwarded, or the uplink on the UE side is restored to complete the data reception, or the stored data expires and is discarded. At this time, the storage space of this specific capacity will be in an idle state with no cached data.

[0004] Therefore, how to efficiently utilize the above-mentioned storage space of specific capacity is the key to improving storage space utilization, meeting the storage and forwarding requirements of more UEs, and providing high-quality on-board storage and forwarding services.

[0133] First, based on the technical solution provided in this application, some technical terms that may be involved are introduced.

[0134] 1. Scenarios where data needs to be stored and forwarded on satellites

[0135] 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.

[0136] 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.

[0137] Currently, there is no solution for how to efficiently use the storage and forwarding space of a storage and forwarding device when the data space has not been released but its data transmission is completed, and there is no solution for how to reuse the storage and forwarding space of a storage and forwarding device when the data of the storage and forwarding device expires but is still within the validity period of the allocated space.

[0138] Based on the analysis, the embodiments of the present application provide an information transmission method, apparatus, terminal and network equipment to improve storage space utilization to meet the storage and forwarding requirements of more UEs and provide high-quality on-board storage and forwarding services.

[0139] 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 embodiments of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0140] like Figure 2 As shown, an embodiment of the present application provides an information transmission method, which is executed by a terminal and includes:

[0141] Step S201, sending first information to a network device;

[0142] The first information is used to instruct the satellite device to release the storage space allocated to the terminal when a first condition is met, and the first condition includes that the data forwarding of the terminal stored is completed; or

[0143] The first information is used to instruct the satellite device to adjust the data storage duration of the terminal and / or adjust the data storage capacity allocated by the satellite device to the terminal.

[0144] It should be noted that the embodiments of the present application can dynamically adjust the storage space and / or data storage duration, thereby improving the utilization rate of the storage space of the satellite equipment to meet the storage and forwarding needs of more terminals and provide high-quality on-board storage and forwarding services.

[0145] Optionally, the satellite device generally refers to a storage and forwarding device arranged on a satellite (also referred to as an on-board storage and forwarding device). The network device mentioned in the embodiment of the present application may be arranged together with the satellite device, or the two may be arranged independently.

[0146] 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).

[0147] 1. The first information is used to instruct the satellite device to release the storage space allocated to the terminal when the first condition is met

[0148] Optionally, in this case, an implementation manner of sending the first information to the network device includes:

[0149] The first information is sent to the network device through a registration request or a protocol data unit (PDU) session establishment request.

[0150] It can be understood that in addition to carrying storage and forwarding related parameters in the registration request or PDU session establishment request, the terminal also needs to carry the first information; further, after receiving the first information, the network device determines that the satellite device releases the storage space when it monitors that the data forwarding of the terminal on the satellite device is completed and the storage space is not invalid. It should be noted here that if the network device and the satellite device are jointly provided, the network device directly releases the storage space when it monitors that the data forwarding of the terminal is completed and the storage space is not invalid; if the network device and the satellite device are independently provided, the network device determines that the satellite device releases the storage space when it monitors that the data forwarding of the terminal on the satellite device is completed and the storage space is not invalid, and then sends a release instruction to the satellite device to realize the release of the storage space by the satellite device.

[0151] It should be noted that by actively releasing the storage space after the data forwarding of the terminal on the satellite device is completed, it is possible to avoid the occupation of the storage space and improve the utilization rate of the storage space of the satellite device.

[0152] 2. The first information is used to instruct the satellite device to adjust the data storage duration of the terminal and / or adjust the data storage capacity allocated by the satellite device to the terminal

[0153] Optionally, in this case, an implementation manner of sending the first information to the network device includes:

[0154] Receiving a first message sent by a network device, where the first message is used to indicate a configuration update reason, or the first message is used to instruct the terminal to adjust a data storage duration and / or a data storage capacity;

[0155] According to the first message, first information is sent to the network device, where the first information is used to instruct the satellite device to adjust the data storage duration of the terminal and / or adjust the data storage capacity allocated to the terminal.

[0156] It should be noted that in this case, the data storage duration and / or data storage capacity can be adjusted, and the adjustment is triggered by the network device side.

[0157] The specific implementation of the present application is illustrated below with examples under different indication contents of the first message.

[0158] 1. The first message is used to indicate the reason for the configuration update

[0159] Optionally, in one implementation, the configuration update reason includes at least one of the following:

[0160] A11. The stored data forwarding time of the terminal has expired;

[0161] A12. The total amount of data stored in the terminal exceeds the allocated data storage capacity.

[0162] It should be noted that in this case, it can be understood that the adjustment of the data storage duration and / or data storage capacity is actively triggered based on the detection of the network device. Optionally, in one implementation, when the network device determines that the second condition is met, the network device sends a first message to the terminal, and the first message carries the configuration update reason;

[0163] The second condition includes at least one of the following:

[0164] A21, the data forwarding time of the stored terminal has timed out;

[0165] A22. The total amount of data stored in the terminal exceeds the allocated data storage capacity.

[0166] It can be understood that the network device performs real-time detection, and as long as it detects that the data forwarding time of the terminal stored in the satellite device has timed out and / or the total amount of terminal data exceeds the allocated data storage capacity, it triggers sending the first message to the terminal.

[0167] Optionally, in one implementation, after receiving the first message, the terminal sends the first information to the network device if it is determined that the data storage duration and / or the data storage capacity needs to be adjusted according to the configuration update reason.

[0168] It should be noted that this situation can be understood as the terminal deciding whether it is necessary to extend the data storage period and / or adjust the data storage capacity after obtaining the reason for the configuration update. If it is determined that it is necessary to extend the data storage period and / or adjust the data storage capacity, the first information is sent to the network device.

[0169] Optionally, in an implementation manner, the sending the first information to the network device includes:

[0170] The first information is sent to the network device via a registration update request or a PDU session modification request.

[0171] Optionally, in order to facilitate the network device to determine the extended data storage duration and / or adjusted data storage capacity, in one implementation, the first message includes: the adjusted data storage duration and / or adjusted data storage capacity.

[0172] It should be noted that this implementation method is that the network equipment actively triggers the adjustment of data storage duration and / or data storage capacity based on detection, thereby improving the utilization rate of the storage space of the satellite equipment to meet the storage and forwarding needs of more terminals and provide high-quality on-board storage and forwarding services.

[0173] 2. The first message is used to instruct the terminal to adjust the data storage duration and / or the data storage capacity

[0174] It should be noted that in this case, it can be understood that the adjustment of the data storage duration and / or data storage capacity is triggered based on the adjustment requirements of the network device based on the third party. Optionally, in one implementation, the network device receives a first configuration parameter sent by the network node, and the first configuration parameter includes at least one of the following: the adjusted data storage duration and / or the adjusted data storage capacity of the terminal;

[0175] A first message is sent to the terminal according to the first configuration parameter, wherein the first message includes: an adjusted data storage duration and / or an adjusted data storage capacity of the terminal.

[0176] Optionally, the network node may be a network exposure function (NEF), a third-party application function (AF), operations and maintenance (OAM), a network data analysis function (NWDAF), etc.

[0177] Optionally, in an implementation manner, the first message includes at least one of the following messages:

[0178] A31, configuration parameter adjustment notification message;

[0179] Optionally, in this case, after the network device obtains the adjusted data storage duration and / or the adjusted data storage capacity, the network device actively adjusts the data storage duration and / or data storage capacity of the satellite device, and only needs to send a notification to the terminal via a configuration parameter adjustment notification message to indicate that the data storage duration and / or data storage capacity has been adjusted.

[0180] A32, a configuration parameter update notification message, wherein the configuration parameter update notification message is used to instruct the terminal to execute a configuration parameter update process;

[0181] Optionally, in this case, after the network device obtains the adjusted data storage duration and / or the adjusted data storage capacity, if the network device cannot actively adjust the data storage duration and / or the data storage capacity, that is, it needs to be adjusted based on the trigger of the terminal, then the network device sends a configuration parameter update notification message to the terminal, and the terminal needs to send the first information to the network device by executing the registration update process or the PDU session modification process, and the first information includes the adjusted data storage duration and / or the adjusted data storage capacity. Furthermore, after the network device obtains the first information sent by the terminal, it needs to adjust the data storage duration and / or the data storage capacity according to the first information.

[0182] It should be noted that this implementation method is that the network equipment triggers the adjustment of data storage duration and / or data storage capacity based on the instructions of a third party, thereby improving the utilization rate of the storage space of the satellite equipment to meet the storage and forwarding needs of more terminals and provide high-quality on-board storage and forwarding services.

[0183] It should be noted that the application architecture of the embodiments of the present application mainly includes the following two types:

[0184] Application Architecture 1. Figure 3As 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).

[0185] 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.

[0186] 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.

[0187] The specific application process of the embodiment of the present application is illustrated below by way of example.

[0188] Application 1: The storage and forwarding device is a storage and forwarding device set up together with AMF. The terminal adds the first information during the registration process.

[0189] like Figure 5 As shown in the figure, the specific implementation process includes:

[0190] Step 501: During a registration process or a session establishment process, a terminal carries first information in addition to storage-and-forwarding related parameters, for indicating whether to release the storage space allocated to the terminal immediately after data transmission of the terminal is completed.

[0191] Step 502: The terminal completes the registration or PDU session establishment process related to store-and-forward.

[0192] Step 503: The storage-and-forwarding device detects that the data transmission of the onboard storage-and-forwarding device is completed and the storage space is not invalid (i.e., the effective duration of the storage space allocated to the terminal has not yet arrived), and decides to release this part of the storage space based on the indication of whether to release the storage-and-forwarding space after the storage-and-forwarding data transmission is completed received from the terminal.

[0193] Optionally, the decision can be executed by AMF; or, if the store-and-forward service is requested by the terminal through the PDU session process, the decision is executed by SMF and forwarded to AMF to transmit the notification to the terminal.

[0194] Application scenario 2: The storage and forwarding device is a storage and forwarding device set up together with AMF. The network side detects that the data forwarding time has expired and / or the total amount of terminal data exceeds the allocated data storage capacity, and initiates a configuration update

[0195] like Figure 6As shown in the figure, the specific implementation process includes:

[0196] Step 601: The terminal applies for a store-and-forward service from an onboard store-and-forward device (registration process or PDU session establishment process).

[0197] Step 602: It is detected that the data forwarding time of the current terminal has expired or the total amount of data of the terminal exceeds the data storage capacity allocated to the current terminal.

[0198] It should be noted that the detection can be performed by AMF, or if the on-board storage and forwarding device is UPF, that is, the terminal applies for storage and forwarding service through a session, then SMF completes the above detection and forwards it to AMF for transmission to the terminal.

[0199] Step 603: Send the terminal configuration update process to the terminal, carrying the configuration update reason (such as the data forwarding time stored for the terminal has expired and / or the total amount of data stored for the terminal exceeds the data storage capacity allocated for the current terminal).

[0200] Step 604: After receiving the configuration update reason in step 603, the terminal decides to continue extending the data storage time and / or adjusting the data storage capacity.

[0201] Step 605: The terminal initiates a registration update or PDU session modification process to the network device according to the decision result of step 604.

[0202] Application scenario 3: The store-and-forward device is a store-and-forward device that is set up together with AMF. The terminal configuration update triggered by AF

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

[0204] Step 701: The terminal applies for a store-and-forward service from an onboard store-and-forward device.

[0205] Step 702: The AF provides the adjusted configuration parameters to the Policy Control Function (PCF) through the NEF, for example, adjusting the data storage capacity and / or data storage duration of the current terminal or session.

[0206] Step 703: If the terminal applies for the store-and-forward service based on the registration process, the PCF sends the adjusted configuration parameters of step 702 to the AMF.

[0207] After executing step 703, the onboard storage and forwarding device may perform one of the following operations:

[0208] Step 703a: Actively adjust the store-and-forward parameters for the current terminal / session, and send a configuration parameter adjustment notification message to the terminal.

[0209] Step 703b: Send a configuration parameter update notification message to the terminal, and the terminal actively initiates a registration update or PDU session modification process.

[0210] It should be noted that only one of step 703a and step 703b will be executed.

[0211] Step 704: If the terminal applies for the store-and-forward service based on the PDU session establishment process, the PCF calls Npcf_SMPolicyControl_UpdateNotify to the SMF, carrying the configuration parameters of step 702;

[0212] Step 704a, SMF adjusts relevant parameters to the storage and forwarding device, and sends a configuration parameter adjustment notification message through AMF;

[0213] Step 704b, SMF decides to send a configuration parameter update notification message to the terminal through AMF according to the configuration parameters in step 702;

[0214] After receiving the configuration parameter update notification message, the terminal initiates a PDU session modification to modify and adjust the parameters of the storage and forwarding device.

[0215] It should be noted that only one of step 704a and step 704b will be executed, that is, when step 704 is executed, one of step 704a and step 704b will be executed later.

[0216] It should be noted that only one of step 703 and step 704 will be executed.

[0217] Step 705: The terminal performs a registration update or a PDU session modification process according to the received configuration parameter update notification message to update relevant parameters of the store-and-forward service.

[0218] It should be noted that step 705 is an optional step, and the terminal will execute step 705 only when the terminal receives a configuration parameter update notification message.

[0219] In summary, the embodiments of the present application improve the utilization efficiency of the storage space of the on-board storage and forwarding device, and can maximize the use of the storage and forwarding space to provide on-board storage and forwarding services for the terminal.
