Solution Overview
Problem
Current end-to-end communications networks face inefficiencies in managing resources across subdomains, leading to inconsistent end-to-end service experiences.
Innovation Solution
A method for mapping and collaborating between subnets in Radio Access Network (RAN), Core Network (CN), and Transport Network (TN) subdomains within an end-to-end subnet, ensuring consistent resource management and quality of service by using identity information to route data packets effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slices are created to provide customized differentiated services for different users, then service customization and user requirements satisfaction are improved, but device complexity and resource management complexity increase
Solution Approach 1:
The patent segments the network into multiple network slices, each independently managing resources for specific services or users. Each slice has its own resource pool and management mechanisms, allowing customized service delivery without requiring the entire network to be reconfigured for each user requirement.
Solution Approach 2:
The patent establishes resource mapping relationships and correspondence between network slices and transport networks in advance, before actual data transmission occurs. This preliminary configuration enables efficient resource allocation and reduces real-time management complexity when handling data packets.
2Adaptability or versatility
If network slices are created to provide customized differentiated services, then service differentiation capability is improved, but system complexity increases
Solution Approach 1:
The network is divided into independent network slices that can be configured and managed separately. Each slice represents a logical segmentation that provides differentiated services while maintaining independent resource pools, reducing the complexity of managing service differentiation across the entire network.
Solution Approach 2:
The patent introduces mapping relationships as intermediary mechanisms between network slices and transport networks. These mappings act as intermediaries that translate service requirements into resource allocation decisions, simplifying the complexity of direct service differentiation management.
3Ease of operation
If subdomains manage resources independently without coordination, then local resource management flexibility is improved, but end-to-end service consistency deteriorates
Solution Approach 1:
The patent establishes universal mapping relationships that work across all subdomains (RAN, CN, TN) within a network slice. These mappings provide a common framework that enables each subdomain to manage resources independently while ensuring consistent end-to-end service delivery through the shared mapping structure.
Solution Approach 2:
The mapping relationships between network slices and transport networks provide feedback mechanisms that enable coordination between subdomains. When resource allocation decisions are made in one subdomain, the mapping relationships ensure corresponding adjustments in other subdomains to maintain end-to-end service consistency.
4Productivity
If identity information is used to route data packets across subdomains, then data transmission efficiency is improved, but information processing requirements increase
Solution Approach 1:
The patent extracts essential identity information from data packets to establish mapping relationships with network slices and transport networks. By taking out only the necessary identification elements rather than processing complete packet information, the system achieves efficient routing while minimizing information processing requirements.
Solution Approach 2:
The mapping relationships between identity information and network resources are established in advance, before actual data transmission. This preliminary action enables fast routing decisions based on pre-configured mappings, reducing real-time information processing requirements while maintaining high transmission efficiency.

AI summary
This application provides a communication method. The method includes: receiving, by a radio access network device, an uplink data packet from a terminal device; learning of, by the radio access network device, identity information of the uplink data packet; and adding, by the radio access network device, the uplink data packet to a transport network subnet based on a correspondence between the identity information of the uplink data packet and the transport network subnet. According to the method, the radio access network device can reliably and efficiently add uplink data to a corresponding transport network subnet for transmission.
