Description

Technical Field

[0001] The present invention relates to the field of base stations, and in particular to a data transmission method and device, a storage medium, and an electronic device. Background Art

[0002] Data communication between devices relies on data transmission protocols. For example, the 3GPP (3rd Generation Partnership Project) introduced a standard protocol supporting NTN (Non-Terrestrial Networks) in Release 17. In Release 17, only terminal devices compatible with the Release 17 protocol can access satellite networks. Terminals running versions prior to Release 17 cannot directly access satellite networks due to protocol limitations.

[0003] In the related technology, devices that only support lower versions of data transmission protocols cannot transmit data through higher versions of data transmission protocols. For example, if a device that only supports R15 and R16 versions of data transmission protocols wants to achieve satellite communication, the device needs to be upgraded. In this way, the devices need to be upgraded one by one.

The process includes the following steps:

[0050] Step S202: receiving a first data transmission request initiated by a first terminal device connected to the first data transmission device, wherein the first data transmission request is used to request transmission of target data to a second terminal device;

It can be understood that the terminal device itself cannot transmit data with the base station. On the one hand, by connecting the terminal device to the data transmission device, the data to be transmitted is transmitted to the base station through the data transmission device. In this way, data transmission between the terminal device and the base station is realized. On the other hand, according to the transmission performance of the base station and the transmission performance of the data transmission device, the data transmission protocol that meets the lower transmission performance is adaptively selected, and the transmission capacity between the data transmission device and the base station is matched, which improves the success rate of data transmission between the data transmission device and the base station.

The data transmission equipment supporting satellite access (e.g., IAB (Integrated access and backhaul) node) is accessed to the base station (e.g., gNodeB) through the data transmission component (e.g., MT (Mobile Termination) module). In this method, the base station (e.g., gNodeB) supports the access function of the IAB node through the satellite. The NTN mode can adopt the transparent transmission mode, and the satellite and the gateway station together serve as the UU interface of NR. The satellite does not perform signal modulation and demodulation processing, and the base station (e.g., gNodeB) completes the signal modulation and demodulation. After the base station (e.g., gNodeB) completes the BAP (Backhaul Adaptation Protocol) layer adaptation processing, it transmits signaling and data to 5GC through the NG interface to complete the access and service transmission of the NR terminal (equivalent to the terminal device).

A data transmission device supporting satellite access (e.g., an IAB (Integrated access and backhaul) node) is connected to a base station (e.g., a gNodeB) through a data transmission component (e.g., an MT (Mobile Termination) module). In this method, the base station (e.g., a gNodeB) supports the access function of a data transmission device (e.g., an IAB (Integrated access and backhaul) node) with satellite access. The NTN mode can be, but is not limited to, a transparent transmission mode, where the satellite and the gateway together serve as the UU interface of the NR. The satellite does not perform signal modulation and demodulation, and the base station (e.g., a gNodeB) completes signal modulation and demodulation. A base station (e.g., a gNodeB) can connect to the MME via the S1-U interface to facilitate access and data transmission for LTE terminals or user equipment. Alternatively, a base station (e.g., a gNodeB) can transmit information to a base station (e.g., an eNodeB) via the X2-C interface. Signaling is then transmitted between the eNodeB and the MME via the S1 interface.

The data transmission equipment supporting satellite access (e.g., IAB (Integrated access and backhaul) node) is accessed to the base station (e.g., gNodeB) through the data transmission component (e.g., MT (Mobile Termination) module). In this method, the base station (e.g., gNodeB) supports the access function of the data transmission equipment (e.g., IAB (Integrated access and backhaul) node) supporting satellite access. The NTN mode adopts a regeneration mode, and the main function of the base station (e.g., gNodeB) is located on the satellite, and the modulation and demodulation processing of the signal is completed on the satellite. After the base station (e.g., gNodeB) completes the BAP (Backhaul Adaptation Protocol) layer adaptation processing, it transmits the information transmitted to the 5GC to the ground through the SRI (Satellite Radio Interface) interface between the satellite and the gateway station, and then forwards it to the 5GC, completing the connection between the terminal device or user equipment and the 5GC.

Figure 2 ,like Figure 6As shown, the data transmission equipment supporting satellite access (e.g., IAB (Integrated access and backhaul) node) supports the access function of R17 version or subsequent evolution version, and the device access component (e.g., LTE Cell module) of the data transmission equipment supporting satellite access (e.g., IAB (Integrated access and backhaul) node) supports access of terminal equipment or user equipment of R8, R9, R10 and later LTE versions. The data transmission equipment supporting satellite access (e.g., IAB (Integrated access and backhaul) node) is accessed to the base station (e.g., gNodeB) through the data transmission component (e.g., MT (Mobile Termination) module).

The NTN mode adopts a regeneration mode, and the main function of the base station (e.g., gNodeB) is located on the satellite, and the modulation and demodulation processing of the signal is completed on the satellite.

[0091] The embodiments of the present application provide a new type of accessible data transmission device with satellite communication capabilities. This device enables common NR commercial terminals (R15, R16) or LTE terminals (e.g., R8, R9, R10, etc.) to connect to a satellite communication network without requiring any terminal-side modifications. This provides a backhaul method without the need for a wired network, improving wireless coverage in areas without a backhaul network. This can effectively reduce data backhaul issues in areas without a wired network, further resolving coverage issues.

[0092] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.

The transmission performance of the terminal device is lower than the transmission performance of the base station. The device is applied to the first data transmission component, such as Figure 7 As shown, the device includes:

[0094] A first receiving module 702 is configured to receive a first data transmission request initiated by a first terminal device connected to the first data transmission device, wherein the first data transmission request is used to request transmission of target data to a second terminal device;
