[0002] With the development of B5G / 6G communication technology, the integrated perception, communication and computing technology has been widely used in artificial intelligence, perception, computing and other service scenarios due to its ability to integrate communication and intelligence, as well as perception and communication. It aims to achieve ubiquitous intelligent connection between people, machines and things, and empower new digital information infrastructure for new applications, which has attracted widespread attention from scholars in the industry.

[0003] The integrated communication, perception, and computing system samples the physical world through perception services, provides connectivity to the physical world through communication services, and optimizes the network and processes perception data through computing services. The integration of communication, perception, and computing enables the deep integration and mutually beneficial enhancement of multi-dimensional perception, collaborative communication, and intelligent computing capabilities, thereby opening a channel for the integration of the physical and digital worlds. It provides diverse capabilities such as positioning, ranging, and imaging, greatly meeting the needs of ultra-high resolution and precision applications. These include location perception, unmanned monitoring, and environmental reconstruction in the field of industrial upgrading; environmental monitoring and hazardous material detection in the field of social governance; and gesture and motion recognition, security monitoring, behavior monitoring, and health monitoring in the field of smart living.

[0004] Existing research on resource optimization for the integrated communication, perception, and computing scenarios involving multi-dimensional and even multi-system resource scheduling focuses solely on optimizing communication, computing, or both. This separates network data perception, communication, and computing, making it difficult to meet the demands of real-time interaction and analysis of massive amounts of perception information. Therefore, there is an urgent need to explore an integrated communication, perception, and computing resource scheduling architecture for efficient delivery and analysis of perception data.

[0005] Considering the differentiated task response requirements and the impact of wireless channel fluctuations caused by fast fading, the constructed resource joint scheduling architecture needs to ensure the stability of perception data delivery and processing on a large time scale, avoiding the problems of queue data backlog and latency jitter degradation caused by traditional instantaneous optimization theoretical frameworks. It must achieve a stable and optimal balance between multiple experienced latency and effective information volume, effectively solving the problem of excessive resource allocation latency in existing integrated communication, perception, and computing scenarios.

[0081] S12. Based on the acquired network status data, the network central control node establishes long-term optimization goals for network asset management.

[0082] The constructed optimization objective is shown below. For the convenience of expression, let t represent the time step, t = 0, t = 1, 2, 3, ..., T, t = T + 1 represent the initial stage, the iteration stage and the end stage respectively, and T represents the number of iteration cycles.

[0083]

[0084] The network central control node evaluates the amount of effective information that can be obtained at each stage based on the established long-term optimization goals, as follows:

[0085] (1) Initial stage and final stage:

[0086] The sensing node is in a delay-sensitive communication mode in the initial and final stages. Therefore, the short packet communication business mode is used in these two stages, where the data size is shorter, the occupied time and frequency resources are less, and the uplink / downlink transmission spectrum efficiency is higher. and local / server computing efficiency For short packet services, the Shannon formula can no longer approximate its communication rate, and it is necessary to calculate the coding rate under a finite code length.

[0087]

[0088] Among them, the signal-to-noise ratio is the short packet communication power of the sensing node And the short packet communication power of the access point function; and Indicates the time-frequency resource blocks occupied by the short packet service in the uplink / downlink communication process; ò is the packet loss rate and also, and is the amount of short packets waiting to be calculated in the local queue and server queue. and is the corresponding computational delay.

[0089] At the end of the initial stage, the effective information that the sensing node u can obtain is:

[0090]

[0091] Among them, ε1 is the packet loss rate in the initial stage, a u,n To sense the node access situation, is the amount of time-frequency resources occupied by the sensing node u during the communication process, in units of s·Hz, is the spectrum efficiency of uplink short packet data transmission between sensing node u and access point n, in bit / s / Hz.

[0092] The effective amount of information that the sensing node u can obtain in the final stage is:

[0093]

[0094] Among them, ε3 is the packet loss rate at the end stage, is the spectrum efficiency of downlink short packet data transmission between sensing node u and access point n, in bit / s / Hz.

[0095] (2) Iteration phase:

[0096] The sensing node uses long packet transmission services for transmission in the iteration phase. Long packet services can also be understood as delay-tolerant services. Their data packets are long, occupying large time-frequency resource blocks and computing resources. Their uplink / downlink transmission spectrum efficiency is low. and local / server computing efficiency The spectral efficiency of transmission is approximately obtained by the Shannon formula.

[0097]

[0098] In the above formula, and is the uplink / downlink communication signal-to-noise ratio of the sensing node, which is the long packet communication power of the sensing node Long packet communication power with access point Function: and are the amount of long packet data to be calculated in the local queue and the server queue respectively, and is the corresponding calculation delay.

[0099] The effective amount of information that the perception node u can obtain in each iteration is:

[0100]

[0101] Among them, ε2 is the packet loss rate in the iteration phase, is the amount of time-frequency resources occupied by the sensing node u during the communication process, in units of s·Hz, is the spectrum efficiency of uplink / downlink long packet data transmission between sensing node u and access point n, in bit / s / Hz.

[0102] S13. Based on the long-term optimization goal of network resource management, the network central control node constructs a multi-dimensional resource adaptive network asset management long-term optimization model training problem for the integrated telecomputing scenario.

[0103] The long-term optimization model of network asset management includes the main network and the target network. Both the main network and the target network are "evaluation network-behavior network" models; the main network includes the main evaluation network and main behavior network The target network includes the target evaluation network and target behavior network For the evaluation network, s u (t) and a u (t) is the input, s u (t) represents the environmental parameter, v u and v u ′ are the model parameters of the two evaluation networks, and the evaluation Q value is output; for the behavior network, s u (t) is the input, η u and η u ′ are the model parameters of the two behavioral networks, a u (t) is the output, which represents the generated decision behavior.

[0104] The set of optimization parameters related to the settings is defined as:

[0105]

[0106] Among them, x u (t)∈[0,1] is the splitting of the sensor data by the sensing node, x u D u and (1-x u )D u The amount of sensor data analyzed locally and analyzed with the help of server; a u,n ∈{0,1} is the network access status of the node. Its value is 1, which means that the target is allowed to access the network when the uplink / downlink communication request is made, and the value is 0, which is the opposite. The amount of computing resources that can be called by each sensing node is h u , the amount of CPU computing resources that the sensing node u can call on the server associated with access point n at time t is h u,n ; is the amount of time-frequency resources occupied by the sensing node u during the initial and final phases (short packet) of communication, in s·Hz; is the amount of time-frequency resources occupied by the sensing node u during the iterative phase (long packet) communication process, in s·Hz;

[0107] The constructed optimization problem is:

[0110] C2: Server CPU resources are limited

[0111] C3: Average experienced latency limit of each sensing node at each stage

[0113] C4: Average delay limit of each queue during the iteration phase

[0114]

[0115]

[0116] C5: Limit on model accuracy loss at the end of the iteration phase

[0117] Among them, the effective information amount that can be obtained in the initial stage, iterative stage and final stage is I init , and I end The server integrated in the access point configures three queues for each sensing node within its service range: Sink queue for sensor data, For reinforcement learning queue, Model training queue, and the data leaving the three queues at time t are Each perception node is equipped with two queues: reinforcement learning queue and model training queue The data leaving the two queues at time t are d u (t) Local sensing data size of sensing node u; D u (t) is the size of the associated data called by the perception node u from the perception network. Each perception node u updates the main evaluation network to minimize the loss function, and the model parameter is ν u , and its loss function is defined as TD t Represents the time series difference error of the sampled tuple at time t.

[0118] S2. For the constructed long-term optimization model of network asset management, the network central control node adopts the Lyapunov method to split the long-term optimization model into multiple time-discrete resource optimization models, and divides each resource optimization model into the initial stage, iterative stage, and end stage in chronological order; the network central control node queries the stage according to the time slot, solves the sub-optimization problem corresponding to the stage, and sends the resource optimization decision to the corresponding perception node.

[0119] S21. In view of the constructed long-term optimization goal, the network central control node adopts the Lyapunov method to convert the long-term optimization model of network asset management into a time-discrete resource optimization model, and divides each resource optimization model into the initial stage, iterative stage, and end stage in chronological order.

[0120] The specific steps are as follows:

[0127] Step 4: Based on each queue in steps 1 to 3, calculate the Lyapunov function:

[0128]

[0129] in, V ite (t) is the auxiliary parameter for queue update.

[0130] Step 5: Define the Lyapunov drift term based on the Lyapunov function to describe the stability of the above delay indicators. The Lyapunov drift term can be expressed as:

[0131] Δ(QV(t))=E[F L (QV(t+1))-F L (QV(t))|QV(t)].

[0132] Step 6: Based on the Lyapunov drift term and the optimization objective of the optimization problem OP1, calculate the Lyapunov drift penalty term:

[0133]

[0134] The drift penalty term satisfies for any constant ξ>0 and any QV(t)

[0145] Step 1: The network central control node schedules the optimization problem OP2.1 in the initial stage and solves the resource optimization problem to optimize the amount of effective information in the initial stage. The resource optimization decision in the initial stage is sent to the network according to the time slot.

[0146] The optimization at this stage can be broken down into:

[0151] Step 2: The network's central control node schedules the optimization problem OP2.2 for each time slot during the iteration phase, solves the resource optimization problem, optimizes the amount of effective information during the iteration phase, and updates the queue in real time. Resource optimization decisions during the iteration phase are distributed to the network according to the time slot.

The resource optimization decision for the end phase is then sent to the network according to the time slot.
