TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a 5G new radio broadcast-based information broadcasting method and device. BACKGROUND

[0002] In the current field of advertising information broadcasting, both traditional broadcast television technology and Internet advertising systems have significant technical limitations, making it difficult to meet the comprehensive needs of modern advertising for high efficiency, precision, and wide coverage. Traditional television advertising relies on specific broadcast frequency bands, with limited transmission rates, making it difficult to support smooth transmission of high-definition, high-capacity advertising content. In addition, the one-way transmission mode lacks user interaction capabilities, and the delivery strategy can only be based on rough time periods and program types, making it impossible to accurately target user groups, resulting in a large waste of advertising resources.

[0003] On the other hand, while the two-way network advertising system based on the Internet has achieved precise delivery and user interaction functions, it highly depends on two-way data transmission, requiring extremely high network bandwidth. During peak delivery periods, it can easily cause network congestion, affecting user experience, and the operating costs are high. In addition, there are natural blind spots in Internet coverage, such as remote mountainous areas, rural areas, and other areas with weak network infrastructure, making it difficult for a large number of potential users to access such information, limiting the spread of advertising information.

[0004] Although 5G new radio (NR) broadcast technology has the technical advantages of high bandwidth, low latency, and wide coverage, it can efficiently transmit high-definition and even 8K ultra-high-definition advertising information and break through geographical limitations to cover areas that traditional networks cannot reach, but it does not solve the problem of how to combine the efficient delivery capabilities of 5G NR broadcast with precise user targeting and achieve quantitative evaluation and closed-loop optimization of information delivery effectiveness.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the current advertising information dissemination field, both traditional broadcast television technology and internet advertising systems have significant technical limitations, making it difficult to meet the comprehensive demands of the modern advertising industry for efficiency, precision, and broad coverage. Traditional television advertising relies on specific broadcast frequencies, resulting in limited transmission rates that struggle to support the smooth transmission of high-definition, large-capacity advertising content. Furthermore, in remote areas, factors such as terrain can lead to signal coverage blind spots, preventing some viewers from receiving the message. In addition, its one-way communication model lacks user interaction capabilities, and its placement strategies are limited to rough time slots and program types, failing to achieve precise targeting of user groups and resulting in a significant waste of advertising resources.

[0031] On the other hand, while internet-based two-way online advertising systems achieve precise targeting and user interaction, they heavily rely on two-way data transmission, placing extremely high demands on network bandwidth. During peak advertising periods, this can easily lead to network congestion, impacting user experience, and also incurs high operating costs. Furthermore, internet coverage has inherent blind spots, such as in remote mountainous areas and rural regions with weak network infrastructure, preventing many potential users from accessing this information and limiting the reach of advertising messages.

[0032] Although 5G New Radio (NR) broadcasting technology has the technical advantages of high bandwidth, low latency and wide coverage, enabling efficient transmission of high-definition and even 8K ultra-high-definition advertising information and breaking through geographical limitations to cover areas that traditional networks cannot reach, it has not solved how to combine the efficient delivery capability of 5G NR broadcasting with precise user targeting, and how to achieve quantitative evaluation and closed-loop optimization of information delivery effectiveness.

[0033] To address this issue, this application proposes an information broadcasting method based on 5G New Radio (NR) broadcasting, aiming to solve the problem that existing technologies cannot effectively utilize the efficient delivery capabilities of 5G broadcasting and the interactive characteristics of bidirectional networks to achieve accurate information delivery and closed-loop optimization. In this embodiment, an information broadcasting method based on 5G NR broadcasting includes:

[0034] Step 101: Perform format conversion and encoding optimization on the multimedia information to be broadcast in order to generate broadcast information that meets the requirements of 5G New Radio broadcast transmission.

[0035] The video information is converted into a first encoding format, and the resolution and frame rate of the video information are adjusted according to the network resource status and the display requirements of the terminal device; the audio information is converted into a second encoding format, and the sampling rate and bit rate of the audio information are configured according to the audio quality and transmission efficiency; the image information is converted into a third encoding format, and the image information is compressed according to the network resource status and the loading requirements of the terminal device.

[0036] Multimedia information typically refers to digital advertising content that includes multiple media formats such as video, audio, and images. In their original state, this content often has different format standards and encoding methods, making it difficult to directly adapt to the transmission requirements of 5G New Radio broadcasting.

[0037] For video information, the system first converts it into a primary encoding format suitable for 5G transmission, such as H.265 or HEVC. This primary encoding format typically employs efficient video coding standards to ensure reduced file size while maintaining image quality. The system monitors network resource status in real time, including key indicators such as available bandwidth and network congestion levels, while also acquiring display requirement information from terminal devices, such as screen resolution and supported maximum frame rate. Based on this information, the system dynamically adjusts the video's resolution and frame rate parameters to ensure that the video content fully utilizes network resources and achieves optimal playback on the target terminal device.

[0038] For audio information processing, the system converts it to a second encoding format, such as AAC, which strikes a balance between audio quality and transmission efficiency. The system precisely configures the sampling rate and bitrate parameters based on the characteristics of the audio content and transmission requirements. The sampling rate directly affects audio fidelity, while the bitrate determines the audio file size and the bandwidth required for transmission. By optimizing these two parameters, the system ensures that audio quality meets user experience requirements while maximizing transmission efficiency.

[0039] During image processing, the system converts the image to a third encoding format, such as JPEG or PNG, and performs intelligent compression based on network resource status and the loading requirements of the terminal device. The system analyzes the real-time transmission capacity of the network and the processing performance of the terminal device, dynamically adjusting the image compression ratio and quality parameters to ensure that the image loads quickly while maintaining sufficient clarity to meet the user's visual needs.

[0040] Step 102: Add metadata tags to the broadcast information; metadata tags include target user characteristics, playback duration, priority, and geographic information.

[0041] Metadata tags serve as supplementary information to broadcast messages, providing a basis for subsequent precise targeting and intelligent scheduling. These tags include elements such as target user characteristics, playback duration, priority, and geographic information.

[0042] The target user characteristic tag details the attributes of the user group to which the broadcast information is intended, including multi-dimensional user profile information such as age range, gender, interests, and professional background. The playback duration tag records the precise duration of the broadcast information, providing important reference for the allocation of transmission resources and the formulation of scheduling plans. The priority tag categorizes broadcast information according to factors such as importance and timeliness requirements, ensuring that high-priority content receives priority transmission resources. The geographic information tag clarifies the geographical scope of the broadcast information, including specific geographical locations, administrative divisions, coverage radius, and other spatial attribute information, laying the foundation for subsequent precise geographic targeting.

[0043] Step 103: In response to the received broadcast request, generate a scheduling plan corresponding to the broadcast information based on the metadata tag and the network resource status of the 5G network, and send the scheduling plan to the 5G core network.

[0044] When the system receives a broadcast request, it will comprehensively analyze the metadata tags and the real-time resource status of the 5G network, and generate the optimal scheduling plan through the scheduling algorithm.

[0045] The scheduling algorithm deeply analyzes network resource status, including key indicators such as current available bandwidth, spectrum resource distribution, base station load, and network congestion level. Combined with metadata tags, the system calculates the most suitable transmission parameters, including transmission rate, modulation scheme, and power allocation. During resource allocation strategy formulation, the system considers the priority differences of different broadcast information, ensuring that high-priority content receives more network resource support. Target area determination is based on geographic information tags and network coverage, using an optimal coverage algorithm to calculate the optimal broadcast area range.

[0046] The generated scheduling plan is sent to the 5G core network in a standardized signaling format, providing detailed execution guidance for subsequent resource allocation and information transmission. The scheduling plan includes complete resource allocation schemes, transmission timing arrangements, target area divisions, and other information to ensure that the 5G core network can accurately execute broadcast tasks.

[0047] Step 104: The 5G core network configures the corresponding broadcast channel resources according to the scheduling plan, so as to send the broadcast information and metadata tags to the target area corresponding to the scheduling plan through the target broadcast channel.

[0048] The configuration of broadcast channel resources involves multiple aspects, including spectrum resource allocation, power parameter setting, and time slot resource arrangement. The 5G core network calculates the required spectrum bandwidth based on the data volume and transmission rate requirements of the broadcast information and selects the most suitable frequency band from the available spectrum resource pool. Power resource configuration needs to consider the coverage requirements and signal propagation characteristics of the target area to ensure that the broadcast information can reliably reach all terminal devices within the target area.

[0049] After configuration, the 5G core network synchronously sends the broadcast information and corresponding metadata tags to the target area specified in the scheduling plan through the target broadcast channel. The broadcast transmission process adopts a point-to-multipoint transmission mode, which can simultaneously cover a large number of terminal devices in the target area, achieving efficient information distribution. During transmission, the 5G core network continuously monitors channel quality and transmission status to ensure that the broadcast information can reach the target terminal completely and accurately.

[0050] Step 105: When the terminal device in the target area receives the broadcast information and metadata tag, it matches the metadata tag with the user preference configuration corresponding to the terminal device. When the match is successful, the broadcast information is decoded and displayed on the terminal device.

[0051] Once the terminal devices within the target area successfully receive the broadcast information and its metadata tags, the device-side intelligent matching mechanism begins operation. The terminal devices first parse the received metadata tags, extracting key elements such as target user characteristics and geographic information, and then perform intelligent matching and judgment against the user preference configuration stored locally on the device.

[0052] The process involves parsing user preference configurations to determine the corresponding interest tags and geographic location tags; using a similarity algorithm, matching target user features with interest tags to determine a first matching score; using a location matching algorithm, matching geographic information with geographic location tags to determine a second matching score; weighting the first and second matching scores according to preset weights to obtain a comprehensive matching score; determining a successful match when the comprehensive matching score is greater than a preset successful matching threshold; and calling the decoder on the terminal device to decode the broadcast information for display.

[0053] User preference configuration includes personalized information such as user-defined interest tags and geolocation tags. Interest tags reflect a user's personal characteristics, including hobbies, areas of interest, and consumption tendencies, while geolocation tags record spatial attributes such as the user's usual location and activity range. The matching algorithm uses a similarity calculation method to compare and analyze the target user characteristics in the metadata tags with the local interest tags, generating a first matching score. Simultaneously, a location matching algorithm compares the degree of fit between geographical information and geolocation tags, calculating a second matching score.

[0054] The system performs a weighted fusion calculation on the two matching scores based on preset weight parameters to obtain a comprehensive matching score. When the comprehensive matching score exceeds a preset successful matching threshold, the system determines that the match is successful, indicating that the broadcast information meets the current user's preferences and needs. After a successful match, the terminal device immediately calls the corresponding decoder to decode the broadcast information and displays it to the user through the device's display system.

[0055] To enable quantitative evaluation and continuous optimization of broadcast performance, the system embeds lightweight data collection code within the broadcast information. This code is transparently integrated into the broadcast content, without affecting the user experience, but automatically triggers data recording when the user interacts with the broadcast information. Interactions include various user behavior patterns such as clicks, viewing duration, sharing behavior, and subsequent visits.

[0056] Data collection code is embedded in the broadcast information. When the terminal device interacts with the broadcast information, data recording is triggered. The data records are transmitted to the data analysis center through a two-way network so that the data analysis center can perform statistical analysis on the data records and generate an effect evaluation report.

[0057] When the data collection code is triggered, the system records detailed interaction data, including interaction time, interaction type, user behavior path, device information, and other metrics. This data is encrypted and then transmitted in real-time to a dedicated data analysis center via a bidirectional network. The use of a bidirectional network ensures the reliability and security of data transmission while supporting large-scale concurrent data uploads.

[0058] After receiving the data records, the data analysis center uses big data analytics to conduct in-depth statistical analysis. The analysis process includes multiple dimensions such as user behavior pattern recognition, quantitative evaluation of broadcast effectiveness, and user preference trend analysis. Ultimately, a detailed effectiveness evaluation report is generated, providing data support for optimizing and adjusting broadcast strategies, thus forming a closed-loop optimization mechanism for broadcast effectiveness.

[0059] As can be seen from the above technical solutions, the beneficial effects of this embodiment are:

[0060] This application provides a method for information broadcasting based on 5G New Radio (NR) broadcasting. The method involves format conversion and encoding optimization of the multimedia information to be broadcast to generate broadcast information that meets the requirements of 5G NR broadcasting transmission; adding metadata tags to the broadcast information; the metadata tags including target user characteristics, playback duration, priority, and geographic information; responding to a received broadcast request, generating a scheduling plan corresponding to the broadcast information based on the metadata tags and the network resource status of the 5G network, and sending the scheduling plan to the 5G core network; the 5G core network configuring corresponding broadcast channel resources according to the scheduling plan to send the broadcast information and metadata tags to the target area corresponding to the scheduling plan through the target broadcast channel; when a terminal device in the target area receives the broadcast information and metadata tags, matching the metadata tags with the user preference configuration corresponding to the terminal device, and decoding and displaying the broadcast information on the terminal device when the match is successful. This method organically combines the efficient transmission capability of 5G NR broadcasting with precise user-targeted delivery, significantly improving the coverage efficiency of information broadcasting and the quality of user experience.

[0061] Figure 1 The example shown is only a basic embodiment of an information broadcasting method based on 5G New Radio broadcasting according to this application. With certain optimizations and extensions, other preferred embodiments of an information broadcasting method based on 5G New Radio broadcasting can be obtained.

[0062] like Figure 2 The image shows another specific embodiment of an information broadcasting method based on 5G New Radio broadcasting according to this application.

[0063] In this embodiment, a method for broadcasting information based on 5G New Radio includes the following steps:

[0064] Step 201: Perform format conversion and encoding optimization on the multimedia information to be broadcast in order to generate broadcast information that meets the requirements of 5G New Radio broadcast transmission.

[0065] Step 202: Add metadata tags to the broadcast information; metadata tags include target user characteristics, playback duration, priority, and geographic information.

[0066] Step 203: In response to the received broadcast request, generate a scheduling plan corresponding to the broadcast information based on the metadata tag and the network resource status of the 5G network, and send the scheduling plan to the 5G core network.

[0067] Step 204: Based on metadata tags and network resource status, calculate the transmission parameters, resource allocation strategy and target area corresponding to the broadcast information through a scheduling algorithm.

[0068] The process involves analyzing network resource status to determine the current available bandwidth and spectrum resource status; calculating the estimated time window required to complete the transmission of the broadcast information based on the playback duration and the amount of data in the broadcast information, combined with the current available bandwidth; determining the processing sequence corresponding to the broadcast information based on priority and the estimated time window; calculating the target area using an optimal coverage algorithm based on geographical information and target user characteristics; allocating target spectrum resources and target power resources to the broadcast information using a heuristic algorithm based on the processing sequence and spectrum resource status, and generating a resource allocation strategy based on the target spectrum resources and target power resources; and determining the transmission rate and modulation scheme corresponding to the broadcast information based on the resource allocation strategy and the 5G New Radio broadcast standard, and generating transmission parameters based on the transmission rate and modulation scheme.

[0069] The system first performs a deep analysis of the current network resource status, acquiring dynamic network status information through real-time data interaction with the 5G core network. This analysis includes precise measurement of available bandwidth and a comprehensive assessment of spectrum resource status. Determining available bandwidth requires considering multiple factors such as instantaneous network load, base station processing capacity, and transmission link quality. The system calculates the actual bandwidth resources available for broadcasting tasks by comprehensively analyzing these parameters. The assessment of spectrum resource status involves monitoring the usage of different frequency bands, including key indicators such as occupancy rate, signal interference level, and propagation characteristics, providing accurate decision-making basis for subsequent spectrum allocation.

[0070] Based on the playback duration and data volume of the broadcast information, the system calculates a precise time window using the currently available bandwidth. This calculation process considers factors such as the actual data transmission rate, network transmission overhead, and possible retransmission mechanisms to ensure the high accuracy of the estimated time window. The system also corrects and optimizes the calculation results based on historical transmission data and network performance models to improve the reliability of the time prediction.

[0071] Determining the processing sequence is a complex decision-making process that comprehensively considers priority and time constraints. The system uses a scheduling algorithm to arrange the optimal processing order based on the priority tags of the broadcast information and the estimated time windows for each piece of information. Higher-priority broadcast information receives earlier processing opportunities and more resource guarantees. For information of the same priority, the system comprehensively sorts them based on factors such as time urgency, resource requirements, and overlap of target areas. This intelligent processing sequence arrangement maximizes the overall efficiency and broadcasting effect of the system.

[0072] The target area calculation employs an optimal coverage algorithm, which comprehensively considers the spatial attributes of both geographic information tags and target user feature tags. The algorithm analyzes the geographical distribution patterns of user features, identifies the clustering areas and activity ranges of the target user group, and then, combined with the geographic constraints of the broadcast information, calculates the target area that achieves optimal coverage. During the calculation process, the system also considers the impact of physical factors such as base station distribution, terrain, and building obstruction on signal propagation to ensure that the calculated target area has good signal coverage quality and transmission reliability.

[0073] Based on a defined processing sequence and spectrum resource status, the system employs a heuristic algorithm to allocate the most suitable target spectrum and power resources for each broadcast message. This heuristic algorithm can quickly find near-optimal solutions under complex constraints, effectively balancing resource utilization efficiency and broadcast quality requirements. Spectrum resource allocation needs to consider factors such as the propagation characteristics, interference levels, and coverage capabilities of different frequency bands, while power resource allocation must balance coverage requirements and energy consumption control objectives. Through heuristic rules and optimization strategies, the system can generate high-quality resource allocation schemes.

[0074] The determination of transmission parameters is the final output of the scheduling algorithm. Based on the generated resource allocation strategy and the technical standards and specifications for 5G New Radio broadcasting, the system accurately calculates the transmission rate and modulation scheme for each broadcast message. Determining the transmission rate requires comprehensive consideration of technical parameters such as allocated spectrum bandwidth, channel quality, and modulation efficiency, while the selection of the modulation scheme must find the optimal balance between transmission reliability and spectral efficiency. The system will select the most suitable modulation scheme based on factors such as the channel environment characteristics of the target area, the receiving capabilities of the terminal equipment, and the quality requirements of the broadcast information.

[0075] Step 205: Generate a scheduling plan based on transmission parameters, resource allocation strategy, and target area.

[0076] The scheduling plan generation process first requires global coordination and optimization of all broadcast tasks. The system checks for resource conflicts, time conflicts, or coverage area conflicts between different broadcast messages and resolves these potential problems through an intelligent conflict resolution mechanism. For resource conflicts, the system reallocates resources based on priority and importance; for time conflicts, the system adjusts the broadcast sequence to ensure that critical information is transmitted on time; for coverage area conflicts, the system optimizes the area division scheme to avoid unnecessary resource waste and signal interference.

[0077] The generated scheduling plan contains detailed execution instructions and control parameters, covering the entire lifecycle of the broadcast task. The plan clearly specifies key information such as the transmission time window, spectrum resources used, transmit power parameters, target coverage area, and modulation and coding scheme for each broadcast message. Furthermore, the scheduling plan includes contingency plans and dynamic adjustment strategies to address unforeseen circumstances such as network status changes and equipment failures.

[0078] Step 206: The 5G core network configures the corresponding broadcast channel resources according to the scheduling plan, so as to send the broadcast information and metadata tags to the target area corresponding to the scheduling plan through the target broadcast channel.

[0079] Step 207: When the terminal device in the target area receives the broadcast information and metadata tag, it matches the metadata tag with the user preference configuration corresponding to the terminal device. When the match is successful, it decodes and displays the broadcast information on the terminal device.

[0080] As can be seen from the above technical solution, the beneficial effects of this embodiment are: through network resource status analysis and intelligent scheduling algorithm design, a significant improvement in the efficiency of broadcast information transmission and a substantial optimization of network resource utilization are achieved. Specifically, by monitoring and analyzing the dynamic status of the network in real time, the system can accurately grasp the availability of network resources, avoiding the resource waste and performance bottlenecks caused by traditional static configuration methods.

[0081] like Figure 3 The image shows another specific embodiment of an information broadcasting method based on 5G New Radio broadcasting according to this application. This embodiment is further described based on the foregoing embodiments.

[0082] In this embodiment, a method for broadcasting information based on 5G New Radio includes the following steps:

[0083] Step 301: Perform format conversion and encoding optimization on the multimedia information to be broadcast in order to generate broadcast information that meets the requirements of 5G New Radio broadcast transmission.

[0084] Step 302: Add metadata tags to the broadcast information; metadata tags include target user characteristics, playback duration, priority, and geographic information.

[0085] Step 303: In response to the received broadcast request, generate a scheduling plan corresponding to the broadcast information based on the metadata tag and the network resource status of the 5G network, and send the scheduling plan to the 5G core network.

[0086] Step 304: The 5G core network configures the corresponding broadcast channel resources according to the scheduling plan, so as to send the broadcast information and metadata tags to the target area corresponding to the scheduling plan through the target broadcast channel.

[0087] Step 305: Calculate the spectrum bandwidth requirement corresponding to the broadcast information based on the transmission rate and modulation method.

[0088] The calculation of spectrum bandwidth requirements must consider not only the data volume of the broadcast information, but also the technical characteristics of the 5G broadcast channel and transmission environment factors. The system determines the number of bits that each symbol can carry based on the selected modulation scheme, and calculates the actual effective data transmission rate by combining coding redundancy and frame structure overhead. Based on this, the system further analyzes the latency requirements and quality assurance requirements of the broadcast information, introducing necessary safety margins and performance headroom into the spectrum calculation.

[0089] During the calculation process, the system also considers the impact of the physical characteristics of wireless channels, such as multipath propagation, Doppler effect, and shadowing fading, on spectrum utilization efficiency. By establishing an accurate channel model and propagation loss prediction mechanism, the system can more accurately assess spectrum requirements in actual transmission environments. Simultaneously, the system dynamically adjusts spectrum bandwidth requirements based on factors such as the geographical features, building density, and user distribution of the target area, ensuring that the calculation results meet both performance requirements and feasibility.

[0090] Step 306: Based on the target area and resource allocation strategy, determine the available broadcast channel frequency bands and time slot resource pools.

[0091] The system first conducts a detailed spectrum environment analysis of the target area. Through real-time spectrum sensing technology and historical data mining, it comprehensively understands key information such as the usage status, interference level, and propagation quality of each frequency band in the area.

[0092] Based on a predetermined resource allocation strategy, the system comprehensively evaluates the applicability of different frequency bands. The evaluation process considers technical indicators such as the frequency band's propagation characteristics, coverage, penetration, and anti-interference capabilities, while also taking into account practical constraints such as regulatory requirements, operator spectrum licensing, and compatibility with other services. Through a multi-dimensional evaluation system, the system selects the set of candidate frequency bands most suitable for the current broadcasting task, i.e., the broadcast channel frequency bands.

[0093] The determination of the time slot resource pool needs to consider the characteristics of the 5G New Radio frame structure and time synchronization requirements. The system analyzes factors such as the availability of different time slots, time conflicts with other transmission tasks, and network load distribution to construct an available time slot resource pool. During the construction process, the system also considers the latency sensitivity and transmission priority of broadcast information, reserving more high-quality time slot resources for high-priority tasks to ensure that critical information can be transmitted in a timely and reliable manner.

[0094] Through intelligent resource detection and analysis mechanisms, the system can update the status information of available resources in real time and dynamically adjust the composition of the resource pool. This adaptive resource management approach not only improves resource utilization efficiency but also enhances the system's adaptability to environmental changes. When network load changes or new interference sources appear, the system can promptly adjust resource configuration strategies to maintain the stability and reliability of broadcast services.

[0095] Step 307: Based on the spectrum bandwidth requirements, broadcast channel frequency bands, and time slot resource pool, determine the broadcast channel resources corresponding to the scheduling plan using a resource optimization algorithm.

[0096] The resource optimization algorithm employs a solution strategy combining mixed integer programming and heuristic search, which significantly improves computational efficiency while ensuring solution quality. The algorithm first establishes a detailed constraint model, including technical constraints such as spectrum continuity, power limitation, interference control, and latency requirements, as well as business constraints such as regulatory compliance and operational strategy constraints. Based on this, the algorithm constructs a multi-objective optimization function, comprehensively considering optimization objectives such as maximizing spectrum efficiency, ensuring transmission reliability, and ensuring fair resource allocation.

[0097] During the optimization process, the system conducts a comprehensive performance evaluation and comparative analysis of different resource configuration schemes. Evaluation indicators include technical metrics such as spectrum utilization, signal quality, coverage effect, and anti-interference capability, as well as economic and management indicators such as resource cost, operational complexity, and expansion flexibility. Through multi-dimensional comprehensive evaluation, the system can identify the optimal resource configuration scheme, ensuring that broadcasting tasks can be executed under the best channel conditions; the optimal channel is the target broadcast channel.

[0098] The algorithm also possesses dynamic optimization and adaptive adjustment capabilities, enabling it to dynamically adjust resource allocation strategies based on real-time changes in network conditions and service requirements. When channel quality degradation, increased interference, or changes in service priorities are detected, the system can quickly recalculate and adjust resource allocation to ensure the continuity and stability of broadcast services. This intelligent dynamic optimization mechanism not only improves the system's robustness but also provides a solid technical foundation for the flexible expansion and upgrading of services.
