Service-Based Wireless Addressing for Selective Core Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies due to hierarchical architectures that lead to resource wastage and excess power consumption, and integration with service-based networks is complicated by centralized back-end ownership, limiting customization and integration capabilities.
Innovation Solution
Implementing a service-based wireless system with an end-to-end routing layer that allows UEs to communicate directly or indirectly with core network services, selecting appropriate access stratum resources and logical channels based on specific addressing schemes, and utilizing proxy services for routing packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a hierarchical architecture is used in wireless communication systems, then system management and control are simplified, but resource wastage and power consumption increase
Solution Approach 1:
The patent segments the core network into multiple independent service instances that can be selectively accessed by UEs. Instead of a monolithic hierarchical structure, the network is divided into discrete services (e.g., messaging, data, voice) that UEs can connect to based on their specific needs, reducing unnecessary power consumption while maintaining manageable complexity through modular service definitions.
Solution Approach 2:
The patent implements dynamic service selection and connection management where UEs can dynamically establish or terminate connections with specific core network services based on real-time requirements. This dynamic approach allows the system to adapt resource allocation and active connections, reducing power consumption when fewer services are needed while maintaining the ability to scale up when required.
2Device complexity
If a centralized back-end ownership model is used, then system control is centralized, but customization and integration capabilities are limited
Solution Approach 1:
The patent segments the centralized back-end into multiple independent service instances that can be individually customized and integrated. Each service operates as a separate entity with its own addressing scheme and communication protocols, allowing different levels of customization and integration while maintaining overall system coordination through the service-based architecture.
Solution Approach 2:
The patent creates a universal service-based interface that allows multiple core network services to be accessed through a common framework. The service-based architecture provides universal communication mechanisms (service names, service instance IDs, standardized protocols) that enable both centralized control and flexible customization/integration of diverse services simultaneously.
3Adaptability or versatility
If UEs communicate with multiple core network services, then service functionality is enhanced, but resource selection and routing complexity increases
Solution Approach 1:
The patent introduces service-based addressing and routing mechanisms that act as intermediaries between UEs and multiple core network services. The standardized service addressing framework (service names, service instance identifiers, service URIs) and routing protocols simplify the complexity of communicating with multiple services by providing a unified interface and automatic routing determination, allowing enhanced service functionality without proportionally increasing UE-side routing complexity.

AI summary
Methods, systems, and devices for wireless communications are described. An end-to-end routing layer may address packets between a user equipment (UE) and core network services offered by a service-based network on a per-core network service basis. A UE may communicate directly with a core network service (e.g., based on a network address associated with the core network service) or indirectly (e.g., through a proxy service). The UE may select access stratum (AS) resources over which to transmit an uplink packet data unit based on the target core network service. The UE may receive control signaling from a distributed unit, a system information block (SIB), or point-to-point signaling from the core network services indicating specific AS resources for each core network service. The UE may select logical channels for transmitting the uplink packet data units to specific core network services based on the AS resources associated with each service.
