[0034] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "plurality" means two or more. The words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not limit them to be different.

[0035] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms thereof, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open, inclusive, that is, "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 indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0036] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0037] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs.

[0038] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0039] As advanced simulation technologies of information technology (IT), represented by "digital twin" (DT), are deeply integrated into future wireless systems, the native new architecture, feature functions, business processes and system performance of 5G-A and 6G wireless systems will be affected and optimized. Based on the real-state digital drive, twin modeling, simulation and pre-verification capabilities of digital twin technology, the various aspects of the operating state of 5G-A and 6G wireless systems can be optimized and enhanced, improving the business service experience of 5G-A and 6G mobile users.

[0040] The basic principle of wireless network digital twin technology is: according to the specific target twin tasks of system users (for example, wireless network operation and maintenance personnel), real-time data collection and modeling fidelity reproduction of specific "physical objects" (i.e., twinned objects) in the real physical network are carried out, so as to construct the corresponding "digital twin" (i.e., the digital space mapping of the "physical object"). In this way, system users can foresee, predict and pre-verify the internal causal relationship such as the trend direction state, condition path effect and other future changes of the "physical object" to a certain extent. Therefore, how to optimize the network based on digital twin technology needs further research.

[0041] In view of this, the present disclosure provides an information configuration method, by obtaining a digital twin simulation report; performing network optimization operations based on the digital twin simulation report. Among them, the digital twin simulation report can be a simulation and test in a virtual environment using digital twin technology before the network actually occurs, and the energy efficiency and load status of the network in the next cycle or a period of time in the future, as well as the response strategies formulated in advance. Therefore, by obtaining the digital twin simulation report and performing network optimization operations based on the digital twin simulation report, the network node can make the network optimization process more efficient, avoid blind trial and error, and reduce unnecessary costs and time waste.

[0042] The technical solution provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, a new radio (NR) mobile communication network using 5G, a future mobile communication network, such as a 5G-A system, a 6G wireless system, or a variety of communication convergence systems, etc., and the embodiments of the present disclosure are not limited to this.

[0043] Figure 1 FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present disclosure. Figure 1As shown, the communication system includes but is not limited to a first node 110, a second node 120, a third node 130 and a core network element 140. Among them. The first node 110, the second node 120 and the third node 130 can send, receive and interact with wireless signals. The first node 110 and the third node 130 are adjacent nodes, and the first node 110 and the third node 130 can send, receive and interact with wireless signals with the core network element 140.

[0044] In this example, the first node may be a network-side device (e.g., base station 1), the second node may be a terminal-side device (e.g., a terminal in a cell served by base station 1), and the third node may be a network-side device adjacent to the first node (e.g., base station 2, which may be a cell adjacent to the cell that mainly serves base station 1). Among them, a base station may provide network services to a terminal in one cell, or to terminals in multiple cells at the same time. Adjacent base stations may exchange signals through the network.

[0045] In this example, the core network element 140 may include an access and mobility management function (AMF), which is mainly responsible for the access and mobility management of terminal users.

[0046] The “first” node, “second” node, “third” node, “first” method, “second” method, “first” method, “second” method, “first” matrix, “second” matrix, “first” part, “second” part in the present disclosure, unless otherwise specified, are only used for descriptive distinction and do not represent the order of precedence or sequence.

[0047] In the present disclosure, the base station may be a base station device in a 4G network, a base station device in a 5G network, or a base station in a future communication system (such as 5G-A, 6G, etc.), etc. The base station may include various macro base stations, micro base stations, home base stations (Femtocell or Home eNodeB), wireless remotes, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity (WIFI) devices, or various network side devices such as primary cells and collaborative cells (secondary cells).

The terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenario. The terminal may also be sometimes referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent or UE device, etc. The embodiments of the present disclosure are not limited.

[0049] It should be understood that Figure 1 is an exemplary structural diagram, Figure 1 The number of devices included in the communication system shown is not limited, for example, the number of first nodes, second nodes, and third nodes is not limited. Figure 1 In addition to the equipment shown, Figure 1 The communication system shown may also include other devices, which is not limited thereto.

[0050] 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 intended to more clearly illustrate 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. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0051] The present disclosure provides an information configuration method. Figure 2 As shown, applied to the first node, the method comprises the following steps:

[0052] S101. The first node obtains a digital twin simulation report.

[0053] S102. The first node performs network optimization operations based on the digital twin simulation report.

[0054] In some embodiments, the digital twin simulation report includes at least one of the following: energy-saving strategy, switching strategy (for example, hard switching, soft switching and other switching methods based on energy efficiency), predicted energy efficiency, predicted energy state (for example, active, high, low, inactive), energy consumption cost (energy cost, EC) (base station-level parameter, displayed by level (the smaller the cost, the lower the cost)).

[0055] In some embodiments, the energy saving strategy includes at least one of the following:

[0056] Power control: Balance coverage and energy consumption by adjusting the transmit power of the base station (eNodeB or gNodeB or 6G base station) and user equipment (UE);

[0057] 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;

[0058] Cell shutdown: During low traffic periods, some cells or carriers can be shut down to reduce unnecessary energy consumption;

[0059] Carrier switching off: When the load is low, some carrier frequencies can be turned off to maintain only the necessary spectrum resources;

[0060] Coordinated multipoint (CoMP): Reduce unnecessary interference and improve energy efficiency through coordination between base stations;

[0061] Carrier aggregation: When demand is low, carriers can be de-aggregated to reduce energy consumption, smart antennas and beamforming;

[0062] Use multiple antenna technologies, such as multiple input multiple output (MIMO) and directional beamforming, to send and receive signals more accurately, thereby reducing power waste;

[0063] Network Slicing: Dynamically allocate network resources based on different service requirements, such as shutting down slicing for specific services during inactive periods.

[0064] Among them, the contents included in the digital twin simulation report will not be repeated one by one later.

[0065] In some embodiments, the network optimization operation includes a network energy-saving optimization operation and / or a mobility optimization operation. For example, the network energy-saving optimization operation includes at least one of the following: merging, activation, and deactivation of cells.

[0066] Mobility management is a strategy that aims to ensure service continuity during mobility by reducing call drops, radio link failures (RLFs), unnecessary handovers, and ping-pong effects. For future high-frequency networks, the frequency of user equipment (UE) handovers between nodes increases due to the reduction in the coverage of a single node, especially for high-mobility UEs. In addition, for applications with strict quality of service (QoS) requirements, such as reliability, latency, etc., the user experience (QoE) is extremely sensitive to handover performance, so mobility management optimization needs to further prevent handover failures and reduce latency during handovers.

[0067] In some embodiments, before the first node obtains the digital twin simulation report, it 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 digital twin capability, so as to select a node with digital twin capability to perform digital twin simulation. Other nodes can assist the node in performing digital twin simulation.

[0068] It is understandable that the data collected by digital twin technology in the RAN network is used to optimize the network optimization decision on the base station side. That is, the energy consumption, efficiency and load status of the next cycle or a period of time in the future are pre-verified by simulation of the wireless network through digital twin technology, and network optimization operations are performed based on the above-mentioned predicted information, such as cell merging, activation, deactivation, etc.; when the base station (including gNB-CU or gNB-DU) is pre-verified by simulation through digital twin, the base station needs to obtain relevant information for simulation pre-verification. The specific process is as follows:

[0069] Case 1: The first node has digital twin capabilities

[0070] In some embodiments, the first node obtains a digital twin simulation report, including: the first node performs a digital twin simulation and generates a digital twin simulation report.

[0071] It can be understood that in case 1, the first node needs to trigger relevant measurements on the second node side and obtain auxiliary information reports on the third node side before the digital twin simulation.

[0072] In some embodiments, the first node sends measurement configuration information to the second node, where the measurement configuration information includes at least one of the following: a measurement object, a report configuration, a measurement identifier, a quantity configuration, a measurement gap configuration, a report duration, and a threshold of the number of switching times;

[0073] The first node receives a measurement report sent by the second node, and the measurement report includes at least one of the following: a measurement identifier, a reference signal received power (RSRP) of a serving cell, a reference signal received quality (RSRQ) of a serving cell, a signal to interference plus noise ratio (SINR) of a serving cell, RSRP of an adjacent cell, RSRQ of an adjacent cell, SINR of an adjacent cell, an energy saving level on the second node side, an energy saving target on the second node side, location information on the second node side, historical mobility information on the second node side, and performance information on the second node side. These will not be described in detail later.

[0074] In some embodiments, the method for the second node to collect measurement reports includes at least one of the following: based on a period configured by a high layer, based on an event trigger, which will not be described in detail below.

[0075] In some embodiments, the first node sends first request information to the third node, where the first request information is used to request an auxiliary information report from the third node side;

[0076] The first node receives first response information sent by the third node, where the first response information includes at least one of the following: an auxiliary information report on the third node side, and indication information on whether the third node has received the first request information.

[0077] In some embodiments, the auxiliary information report on the third node side includes at least one of the following: identification information of the third node, current energy efficiency status of the third node, current resource status of the third node, current energy status of the third node, key indicators of the third node, traffic pattern of the third node, information on network coverage effect of the third node, and mobility information report of the third node.

[0078] In some embodiments, the first request information includes at least one of the following: identification information of the third node, a method for the third node to send auxiliary information reports, a response period of the third node, indication information that auxiliary information report upload is based on real-time transmission, a response trigger condition of the third node, and indication information for stopping sending auxiliary information reports.

[0079] Among them, the auxiliary information report in this disclosure may also have other names, such as energy efficiency-related information, digital twin simulation auxiliary information, etc. Correspondingly, the first request information may also have other names, such as data collection request information, energy efficiency-related request information, request for digital twin simulation auxiliary information, etc., and this disclosure does not limit this.

[0080] For example, Figure 3 As shown, the first node is base station 1, the second node is a terminal (UE) connected to base station 1, and the third node is base station 2 adjacent to base station 1. When base station 1 (with digital twin capability) performs digital twin simulation and generates a digital twin simulation report, and performs network energy-saving optimization operations based on the digital twin simulation report, the specific process involves at least one of the following:

[0081] Step 1-1, base station 1 sends measurement configuration information to the terminal.

[0082] The measurement configuration information includes at least one of the following: measurement objects (for example, the network can configure a list of cell-specific offsets, a list of "blacklist" cells, and a list of "whitelist" cells), report configuration (for example, reporting criteria (reporting based on a period, reporting based on a measurement event threshold trigger, reporting only once), reference signal type, report format), measurement identifier (for example, measurement identifier list), quantity configuration (filter coefficients for L3 filtering of measurement values), measurement gap configuration (measurement period used by the terminal to perform), report duration, and threshold value for the number of switching times.

[0083] Step 1-2, base station 1 receives the measurement report sent by the terminal. The measurement report is obtained by the terminal performing relevant measurements and collecting the indicated measurement information after receiving the measurement configuration information. The terminal collects measurement reports by at least one of the following methods: based on a period configured by a high-level layer, based on event triggering (terminal state transition, terminal leaving the service cell, duration of the terminal report expires, reaching a certain number of switching times). The terminal collects measurement reports by at least one of the following methods: based on a period configured by a high-level layer, based on event triggering (terminal state transition, terminal leaving the service cell, duration of the terminal report expires, reaching a certain number of switching times). They will not be described one by one below.

[0084] The measurement report includes at least one of the following: measurement identification, RSRP of the serving cell, RSRQ of the serving cell, SINR of the serving cell, RSRP of the neighboring cell, RSRQ of the neighboring cell, SINR of the neighboring cell, energy saving level of the terminal, energy saving target of the terminal, location information of the terminal (such as coordinates of the terminal, ID of the serving cell, speed of movement), historical movement information of the terminal, performance information of the terminal (such as average data packet delay, average UE throughput downlink, average UE throughput uplink, average data packet error rate). They will not be described one by one below.

[0085] Step 1-3: Base station 1 sends first request information to base station 2 through class 1 signaling, where the first request information is used to request an auxiliary information report from base station 2.

[0086] The first request information includes at least one of the following:

[0087] identification information of base station 2;

[0088] The manner in which base station 2 sends the auxiliary information report, such as responding once based on Class 1 type signaling, responding multiple times based on one request, or initiating a reply response based on an event trigger;

[0089] The response period of base station 2;

[0090] The auxiliary information report uploads the indication information based on real-time transmission. For example, after receiving the information requesting digital twin simulation, it is directly reported to base station 1;

[0091] The response triggering condition of base station 2 includes at least one of the following: a throughput exceeding or falling below a threshold configured by base station 1, a delay exceeding or falling below a threshold configured by base station 1, a packet loss rate exceeding or falling below a threshold configured by base station 1, a reliability exceeding or falling below a threshold configured by base station 1, a traffic exceeding or falling below a threshold configured by base station 1, a signal quality exceeding or falling below a threshold configured by base station 1, a network energy consumption exceeding or falling below a threshold configured by base station 1, an energy efficiency level of base station 2 exceeding or falling below a threshold configured by base station 1, an energy efficiency level of base station 2 exceeding or falling below a threshold configured by base station 1, a coverage range of base station 2 exceeding or falling below a threshold configured by base station 1, a signal quality of base station 2 exceeding or falling below a threshold configured by base station 1, etc.;

[0092] The indication information for stopping sending the auxiliary information report is used to instruct the base station 2 to stop periodically or trigger reporting of the auxiliary information report.

[0093] Step 1-4: Base station 1 receives first response information sent by base station 2 via class 1 signaling, where the first response information includes an auxiliary information report on the base station 2 side.

[0094] Step 1-5: Base station 1 performs digital twin simulation based on the measurement report and the auxiliary information report on the base station 2 side and generates a digital twin simulation report.

[0095] Step 1-6: Base station 1 performs network energy-saving optimization operations based on the digital twin simulation report.

[0096] In some examples, steps 1-4 above can be replaced by the following steps:

[0097] Step 1-4-1, base station 1 receives first response information sent by base station 2 through class 1 type signaling, where the first response information includes indication information of whether base station 2 has received second request information;

[0098] Step 1-4-2: When the first response information includes indication information that base station 2 has received the second request information, base station 2 sends an auxiliary information report on the base station 2 side to base station 1 through class 2 signaling.

[0099] Among them, the above-mentioned class 1 type request / response information and class 2 type auxiliary information report are transmitted by reusing the existing terminal-related or non-terminal-related signaling of the NG or XN interface, or by using a newly defined terminal-related or non-terminal-related signaling process; the terminal-related signaling is used to simulate the energy efficiency of the terminal side, and the non-terminal-related signaling is used to simulate the energy efficiency of the base station.

[0100] The auxiliary information report from the base station 2 side is sent to the base station 1, which includes at least one of the following: sending an auxiliary information report once based on the request information, sending multiple auxiliary information reports based on the request information, actively reporting the auxiliary information report based on the previous request information, and starting the sending of the auxiliary information report based on an event trigger.

[0101] The auxiliary information report requested by the first request information from the base station 2 or the auxiliary information report sent by the base station 2 to the base station 1 includes at least one of the following:

[0102] Identification information recognized by base station 2;

[0103] The current energy efficiency status of base station 2;

[0104] The current resource status of base station 2;

[0105] The current energy state of base station 2 (e.g., active, inactive, high, low);

[0106] Key indicators of base station 2 (for example, network performance indicators such as throughput, delay, packet loss rate, and reliability);

[0107] Traffic pattern of base station 2 (e.g., traffic type, traffic size, traffic distribution, etc.);

[0108] The network coverage effect of base station 2 (such as coverage range, signal quality, etc.).

[0109] Step 1-5: After receiving the measurement report from the terminal and the auxiliary information report from base station 2, base station 1 performs digital twin simulation based on the measurement report and the auxiliary information report, and generates a digital twin simulation report.

[0110] Step 1-6: Base station 1 performs network energy-saving optimization operations based on the digital twin simulation report.

[0111] Among them, in the specific implementation order of step 1-1, step 1-2, step 1-3 and step 1-4 in this example, if step 1-1 is before step 1-2 and step 1-3 is before step 1-4, there can also be other implementation orders, for example, the specific implementation order is: step 1-1, step 1-3, step 1-4, step 1-2. Moreover, step 1-1 and step 1-3 can be executed at the same time, which is not limited in this example.

[0112] Case 2: The third node has digital twin capabilities but the first node does not have digital twin capabilities

[0113] In some embodiments, the first node obtains a digital twin simulation report, including: the first node receives the digital twin simulation report sent by the third node.

[0114] The third node is a node adjacent to the first node.

[0115] It can be understood that in situation 2, the third node needs the first node to trigger relevant measurements on the second node side and obtain the measurement report on the second node side and the auxiliary information report on the first node side before the digital twin simulation.

[0116] In some embodiments, the first node sends measurement configuration information to the second node; and the first node receives a measurement report sent by the second node.

[0117] In some embodiments, the first node sends a second request message to the third node, where the second request message is used to request the third node to perform a digital twin simulation, and the second request message includes a measurement report of the second node and / or an auxiliary information report on the first node side.

[0118] In some embodiments, the first node receives a second response message sent by the third node, and the second response message includes at least one of the following: whether the third node receives the second request message and the digital twin simulation report on the third node side.

[0119] In some embodiments, the auxiliary information report on the first node side includes at least one of the following:
