Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 5G communication networks are connection-oriented and cannot execute perception tasks efficiently, leading to increased latency and resource wastage due to the inability to effectively manage perception tasks within specific area ranges.
Innovation Solution
A communication method where a core network functional entity receives request information for a perception task, sends configuration information to an access network device, which then configures a terminal device to execute the task within a subset area range, reducing latency and resource usage by optimizing the selection of connected terminal devices and minimizing unnecessary task execution.

Engineering Contradiction Analysis
1Productivity
If a conventional connection-oriented communication mode is used, then the network can maintain simple connection management, but it cannot execute perception tasks efficiently, leading to increased latency and resource wastage
Solution Approach 1:
The patent segments the perception task delivery process into two distinct paths: a control plane path for task configuration and assignment, and a user plane path for actual perception data transmission. This segmentation allows independent optimization of each path, enabling efficient task delivery without disrupting existing connection-oriented communication frameworks.
Solution Approach 2:
The system performs preliminary actions by pre-configuring terminal devices with perception task capabilities and area range information before actual perception tasks are triggered. The core network functional entity pre-establishes the relationship between terminal devices, area ranges, and perception task types, enabling immediate task execution when triggered without latency-inducing setup procedures.
2Measurement precision
If the core network functional entity performs terminal device-level division, then task assignment precision is improved, but access network device complexity increases
Solution Approach 1:
The patent extracts the complex task assignment and terminal device selection logic from the access network device and relocates it to the core network functional entity. The access network device is left with simplified functions of forwarding messages and executing straightforward task assignments, while the core network functional entity handles the computationally intensive tasks of determining optimal terminal devices based on area ranges and device capabilities.
Solution Approach 2:
The core network functional entity acts as an intermediary between the task trigger source and the access network device. It receives task requirements, determines appropriate terminal devices based on area ranges and capabilities, and then instructs the access network device to execute the simplified assignment, thereby shielding the access network device from complex decision-making logic.
3Loss of energy
If the second area range is set as a proper subset of the first area range, then resource wastage is reduced, but the configuration complexity increases
Solution Approach 1:
The patent applies local quality by differentiating the area range configuration into two levels: a broader first area range for general task eligibility and a narrower second area range for actual task execution. Terminal devices are configured with both ranges, allowing the system to efficiently filter devices based on the stricter second area range criteria only when necessary, reducing unnecessary resource allocation while maintaining clear configuration structures.

AI summary
A communication method includes receiving, by a core network functional entity, request information of a perception task from a task trigger source. The request information includes first area range information. The first area range information indicates to execute the perception task within a first area range. The communication method also includes sending, by the core network functional entity, first configuration information of the perception task to an access network device. The first configuration information includes an identifier of a communication device and second area range information. The second area range information indicates to execute the perception task within a second area range. The second area range is a subset of the first area range.
