Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in efficiently managing complex services and scenarios due to inflexible access network architectures, leading to increased deployment and maintenance costs, and difficulties in supporting diverse service types with low latency and high reliability.
Innovation Solution
The implementation of a wireless communication network architecture partitioned into layered domains, including a cell group stratum, non-cell-group stratum, and non-access stratum, using pre-defined interfaces for communication and service management, with domain-specific functions such as control, enforcement, data storage, and intelligence planes, facilitating modular and flexible operation.

Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional monolithic access network architecture is used, then network control and management are centralized and straightforward, but the network lacks flexibility and adaptability to support diverse service types with low latency and high reliability
Solution Approach 1:
The access network is divided into multiple independent network domains including control domain, user domain, management domain, and operation domain. Each domain is further segmented into specific functional units such as control plane functions, user plane functions, management functions, and operation functions. This segmentation enables each domain to operate independently with specialized functions, improving network flexibility and adaptability while maintaining manageable complexity through clear domain boundaries and standardized interfaces.
2Ease of manufacture
If network functions are tightly coupled in a unified architecture, then deployment and maintenance are simpler, but deployment costs and maintenance costs increase, and it becomes difficult to support diverse service requirements
Solution Approach 1:
The network architecture segments functions into independent domains (control, user, management, operation) that can be deployed separately. Each domain contains specific functional units that can be instantiated and configured independently based on service requirements. This allows operators to deploy only the necessary domains and functions for each service scenario, reducing deployment complexity while supporting diverse services through selective function instantiation.
Solution Approach 2:
The standardized service-based interfaces between domains enable universal communication and coordination across different network domains. The same interface mechanisms can support multiple service types and scenarios, allowing the network to provide diverse services (eMBB, URLLC, mMTC) through different configurations of the same domain structures rather than requiring separate specialized architectures for each service.
3Reliability
If a rigid network architecture is used, then network operations are predictable and stable, but operational costs and maintenance costs increase, and the network cannot efficiently adapt to changing service demands
Solution Approach 1:
The network architecture enables dynamic configuration and orchestration of domain functions based on service demands. The control domain can dynamically allocate resources and coordinate with user and management domains to adapt to changing traffic patterns and service requirements. This dynamic capability improves operational efficiency by allowing the network to respond to real-time conditions while maintaining stability through the structured domain boundaries and standardized interfaces that preserve predictable behavior.

AI summary
Methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to operating an access network with multiple domains. In an example embodiment, a method for wireless communication can include receiving, at a physical resource group control function, a first message on a service-based interface provided by the physical resource group control function. The method may also include, in response to receiving the first message, transmitting, by the physical resource group control function, a second message on the service-based interface provided by the physical resource group control function.
