[0034] In the subsequent description, the suffixes such as "module", "component", or "unit" used to represent elements are only for the convenience of the description of the present disclosure, and have no specific meaning in itself, so "module", "component", or "unit" can be used interchangeably.

[0035] In the description of the disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this document is only a description of the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "multiple" means two or more. The terms "first", "second", and the like do not limit the quantity and execution order, and the terms "first", "second", and the like do not necessarily mean different.

[0036] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms such as "comprises" and "comprising" are interpreted to be open, inclusive meanings, i.e. "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" and the like are intended to mean that the specific features, structures, materials or characteristics related to the embodiment or example are included in at least one embodiment or example of the disclosure. The illustrative representation of the above terms does not necessarily mean the same embodiment or example.

Therefore, the features limited by "first", "second", and the like can explicitly or implicitly include one or more features. In the description of the disclosure, unless otherwise specified, the meaning of "multiple" is two or more.

[0038] In the embodiments of the disclosure, the expressions "exemplarily" or "for example" and the like are used to mean as an example, illustration or description.

[0039] In addition, the use of "based on" means open and inclusive, as a process, step, calculation, or other action that is "based on" one or more stated conditions or values can in practice be based on additional conditions or values beyond those stated.

[0040] With the deep integration of information technology (IT) advanced simulation technology represented by "digital twin (DT)" into future wireless systems, the native new architecture, feature functions, business processes, and system performance of 5G-A systems and 6G wireless systems will be affected and optimized to some extent. Based on the real state digital driving, twin modeling, simulation, and pre-validation capabilities of digital twin technology, the operating state of 5G-A and 6G wireless systems can be optimized and enhanced in various aspects, thereby improving the service experience of 5G-A and 6G mobile users.

[0041] The basic principle of wireless network digital twin technology is that according to the specific target twin task of system users (for example, wireless network operation and maintenance personnel), real-time data collection and modeling of specific "physical object body" (i.e., the object to be twinned) in the real physical network is performed to construct the corresponding "digital twin body" (i.e., the digital space mapping of the "physical object body"). Therefore, the system user can predict and pre-validate the trend direction, condition path effect, and other internal causal relationships of the future transition of the "physical object body". Therefore, how to optimize the network based on digital twin technology needs further research.

[0042] Therefore, the present disclosure provides an information configuration method. The method obtains a digital twin simulation report and performs a network optimization operation based on the digital twin simulation report. The digital twin simulation report can be a simulation and test in a virtual environment using digital twin technology before the actual occurrence of the network, a prediction or pre-validation of the energy efficiency and load state of the network in the next period or a future period of time, and a prepared response strategy. Therefore, the network node can make the network optimization process more efficient, avoid blind trial and error, and reduce unnecessary cost and time waste by obtaining the digital twin simulation report and performing the network optimization operation based on the digital twin simulation report.

[0043] The technical solutions provided by the embodiments of the present disclosure can be applied to various mobile communication networks, such as new radio (NR) mobile communication networks using 5G, future mobile communication networks (such as 5G-A systems, 6G wireless systems), or various communication fusion systems, etc., and the embodiments of the present disclosure are not limited thereto.

Among them, one base station can provide network services to the terminals in one cell, or can simultaneously provide network services to the terminals in multiple cells. Adjacent base stations can interact with each other through the network.

[0046] In the present example, the core network element 140 can include an access and mobility management function (AMF), which is mainly responsible for access and mobility management of terminal users.

[0050] It should be understood that FIG. 1 is an exemplary structural diagram, and the number of devices included in the communication system shown in FIG. 1 is not limited, for example, the number of first nodes, second nodes and third nodes is not limited. In addition, in addition to the devices shown in FIG. 1, the communication system shown in FIG. 1 can also include other devices, which are not limited.

[0051] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0052] The embodiments of the present disclosure provide an information configuration method. As shown in FIG. 2, the method is applied to a first node, and the method comprises the following steps.

[0053] S101, the first node acquires a digital twin simulation report.

[0054] S102, the first node performs network optimization operation based on the digital twin simulation report.

[0055] In some embodiments, the digital twin simulation report includes at least one of the following: energy saving strategy, switching strategy (e.g., hard switching, soft switching, etc. switching method based on energy efficiency purposes), predicted energy efficiency, predicted energy state (e.g., active, high, low, inactive), energy cost (EC) (a parameter at the base station level, displayed by level (the smaller the cost, the lower the cost)).

[0056] In some embodiments, the energy saving strategy includes at least one of the following:

[0057] Power control: balancing coverage and energy consumption by adjusting the transmission power of base stations (eNodeB or gNodeB or 6G base station) and user equipment (UE);

[0058] Sleep mode (eDRX and PDRX): Enhanced Discontinuous Reception (eDRX) and Power Saving Mode (PDRX) allow the UE to enter a low-power state when there is no data transmission for a long time;

[0059] Cell shut down: during periods of low traffic, some cells or carriers can be turned off to reduce unnecessary energy consumption;

[0060] Carrier switching off: when the load is low, some carriers can be turned off, only maintaining the necessary spectrum resources;

[0061] Coordinated multipoint (CoMP): through inter-base station coordination, reduce unnecessary interference and improve energy efficiency;

[0062] Carrier aggregation: when the demand is low, the carrier can be de-aggregated to reduce energy consumption, smart antennas and beamforming;

[0063] Use multi-antenna technology (such as multiple input multiple output (MIMO)) directional beamforming to more accurately transmit and receive signals, thereby reducing power waste;

[0064] Network slicing: dynamically allocate network resources according to different service needs, such as closing specific service slices during periods of inactivity.

[0065] Wherein, the contents contained in the digital twin simulation report are no longer described one by one.

[0066] In some embodiments, the network optimization operation comprises a network energy saving optimization operation and / or a mobility optimization operation. For example, the network energy saving optimization operation comprises at least one of the following: merging, activating, deactivating, etc. of cells.

[0067] Mobility management is a strategy aiming to ensure continuity of service during mobility by reducing call drops, radio link failure (RLF), unnecessary handovers, and ping-pong effects. For future high-frequency networks, due to the reduced coverage of a single node, user equipment (UE) switches between nodes more frequently, especially for high-mobility UEs. In addition, for applications with strict quality of service (QoS) requirements (such as reliability, delay, etc.), the user's quality of experience (QoE) is extremely sensitive to handover performance, so mobility management optimization needs to further prevent handover failures and reduce the delay in the handover process.

[0068] In some embodiments, before obtaining the digital twin simulation report, the first node needs to determine whether itself or a related node (for example, a third node adjacent to the first node, a core network element) has the capability of digital twin, so as to select a node with the capability of digital twin for digital twin simulation, and other nodes can assist the node in digital twin simulation.

[0069] It can be understood that the data collected in the radio access network (RAN) network can be used to optimize the network optimization decision on the base station side by using the digital twin technology. That is, by using the digital twin technology, the energy consumption, efficiency, and load status of the next period or future period of time are simulated and pre-verified for the wireless network, and based on the pre-verified information, network optimization operations are performed, such as merging, activating, deactivating, etc. of cells; in the case of simulation and pre-verification by the base station (including gNB-CU or gNB-DU) through digital twin, the base station needs to obtain relevant information for simulation and pre-verification, and an example process is as follows:
