Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and more specifically, to a distributed ledger technology (DLT) information transmission method and a computer program product. Background Technology

[0002] To achieve its vision of trustworthiness, 6G introduces Distributed Ledger Technology (DLT), forming a native 6G distributed ledger. DLT reaches a final decision through multi-party consensus among nodes; each piece of information requiring a decision must be sent from the node that generates the information to all nodes participating in the consensus. Traditional mobile communication systems are centrally controlled by the core network, with uplink and downlink traffic for each node managed through system scheduling—an end-to-end process from the terminal to the core network and then to the data network. However, DLT information exchange differs from traditional data transmission; information exchange occurs between any nodes, including core network units and terminals.

[0003] Current data exchange processes are point-to-point, such as user information being transmitted from a base station to the core network, which then forwards it to another user. DLT messages differ from this point-to-point data transmission. After generating DLT information, the generating node needs to send the information to other involved nodes within a certain timeframe. In mobile communication networks with native DLT, distributed ledger nodes include terminals and core network nodes. The existing known DLT transmission flow in mobile communication networks is also an end-to-end transmission from the core network-controlled terminal to the core network; other nodes cannot determine the information transmission time themselves, which does not conform to the fundamental characteristics of distributed ledgers.

[0004] In summary, the relevant technologies cannot achieve autonomous transmission of distributed ledger information between nodes. Summary of the Invention

[0005] This invention provides a distributed ledger technology (DLT) information transmission method and computer program product to at least solve the problem in related technologies that the autonomous transmission of distributed ledger information between nodes cannot be achieved.

[0008] According to yet another embodiment of the present invention, a computer-readable storage medium is also provided, wherein a computer program is stored therein, wherein the computer program is configured to perform the steps in any of the above method embodiments when it is run.

[0026] This invention provides a DLT information transmission method. Figure 2 This is a flowchart of DLT information transmission according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0027] Step S202: The terminal access node obtains the distributed ledger (DLT) information.

[0028] In this embodiment of the invention, the terminal access node is a terminal or terminal device. The terminal device can be a mobile phone, an IoT device, or other types of terminals.

[0029] In this embodiment of the invention, the type of Distributed Ledger Technology (DLT) is not specifically limited. A Distributed Ledger Technology (DLT) may include at least one of the following: a single-chain blockchain; a multi-chain blockchain; or a directed acyclic graph (DAG).

[0030] In this embodiment of the invention, DLT information can be blockchain information, which can be blockchain transaction information, blockchain consensus-related information such as pre-preparation information in PBFT, or blockchain ledger information.

[0031] In one exemplary embodiment, the terminal access node obtains the DLT information by: the terminal access node generating the DLT information; or, the terminal access node receiving the DLT information.

[0032] In step S204, the terminal access node sends the DLT information to the core network.

[0033] In an exemplary embodiment, the terminal access node sends DLT information to the core network, including: the terminal access node sends a first DLT signaling carrying DLT information to the core network through the N1 interface based on the Physical Uplink Control Channel (PUCCH), wherein the first DLT signaling is generated by the Non-Access Stratum (NAS).

[0034] In an exemplary embodiment, the terminal access node sends DLT information to the core network, including: the terminal access node sends a first DLT signaling to the access and mobility management function (AMF) of the core network via the N1 interface based on the PUCCH, so that the AMF forwards the first DLT signaling to the DLT node of the core network.

[0035] In this embodiment of the invention, the terminal carries DLT information through the PUCCH channel and DLT signaling, and sends it to the AMF through the N1 interface. The AMF forwards the DLT signaling to the core network DLT function node.

[0036] In an exemplary embodiment, the terminal access node sends DLT information to the core network, including: the terminal access node sends a second DLT signaling carrying DLT information to the core network via the N2 interface based on the PUCCH, wherein the second DLT signaling is generated by the Radio Resource Control Layer (RRC).

[0040] In this embodiment of the invention, the aforementioned QoS Flow is dedicated to DLT information transmission, that is, specifically for blockchain information transmission. In actual implementation, the QoS Flow parameters and functions are defined to achieve a QoS Flow dedicated to DLT information transmission.

[0041] In an exemplary embodiment, the terminal access node sends DLT information to the core network, including: the terminal access node sends QoS Flow to the user plane function (UPF) of the core network through the N3 interface based on the physical uplink shared channel, so that the UPF sends DLT information to the session management function (SMF) of the core network through the N4 interface.

[0042] In this embodiment of the invention, a new blockchain-specific QoS Flow is defined. The terminal uses the PUSCH channel to carry DLT information using the DLT-specific QoS Flow and sends it to the UPF via the N3 interface. The UPF forwards the information to the DLT function node in the core network via the SMF.

[0043] This invention also provides a DLT information transmission method. Figure 3 This is another flowchart of DLT information transmission according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0050] In an exemplary embodiment, the core network sends DLT information to the terminal access node, including: the core network's AMF sending a first DLT signaling message carrying DLT information to the terminal access node through the N1 interface, wherein the first DLT signaling message is generated by the non-access stratum (NAS).

[0051] In this embodiment of the invention, the AMF of the core network sends the first DLT signaling carrying DLT information to the terminal through the N1 interface via the PUCCH channel.

[0052] In an exemplary embodiment, the core network sends DLT information to the terminal access node, including: the core network's AMF sending a second DLT signaling carrying DLT information to the terminal access node through the N2 interface, wherein the second DLT signaling is generated by the Radio Resource Control (RRC) layer.

[0053] In this embodiment of the invention, the AMF of the core network can also use the PUCCH channel to send the second DLT signaling carrying DLT information to the terminal through the N2 interface.
