Wireless Core Network Service States for Fast, Low-Power UE Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems lack mechanisms for individually activating and deactivating core network services at user equipment (UE), leading to inefficient resource usage and high power consumption due to unnecessary processing across multiple devices in a hierarchal architecture.
Innovation Solution
Implement signaling and mechanisms that allow UEs to subscribe to core network services, maintain context information for active and inactive services, and enable network entities to manage service states, facilitating quick re-establishment and efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all core network services are continuously active at UE, then service availability is improved, but power consumption and resource usage increase
Solution Approach 1:
The patent implements dynamic service state management where core network services can transition between active, inactive, and suspended states based on current needs. The UE and network can selectively activate only required services, allowing the system to adapt its resource consumption to actual service demands rather than maintaining all services continuously active.
2Use of energy by moving object
If service activation/deactivation mechanisms are implemented, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent segments service management into distinct states (active, inactive, suspended) with specific transition rules for each state. This segmentation allows the complex service management functionality to be broken down into manageable, well-defined state transitions, reducing the overall complexity compared to a monolithic service control mechanism.
Solution Approach 2:
The patent introduces service state indicators and transition signaling as intermediary elements that mediate between the UE and core network services. These intermediaries manage the complexity of service activation/deactivation by providing standardized interfaces and procedures, shielding the underlying complexity from both the UE and network entities.
3Speed
If context information is maintained for inactive services, then service re-establishment speed is improved, but memory usage increases
Solution Approach 1:
The patent applies local quality by maintaining context information selectively - only for services that are inactive but may need quick re-establishment. The UE decides on a per-service basis whether to maintain context, allowing memory resources to be allocated locally to specific services based on their individual re-establishment requirements rather than uniformly maintaining context for all services.

AI summary
Methods, systems, and devices for wireless communications are described. In the context of a service-based wireless system, a user equipment (UE) may communicate with one or more core network services offered by a service-based network, where respective core network services are in one of an active, inactive, or unconnected state at the UE. The UE may be configured to maintain service contexts for communicating with core network services that are in an active or an inactive state at the UE, where signaling between the UE and each respective core network service may be used to activate or deactivate the respective core network services at the UE between the active and inactive states. By maintaining service contexts for inactive core network services, the UE may be able to quickly and efficiently resume communications with a core network service in accordance with the stored service context upon activating the core network service.
