Inactive-State Uplink Routing Without Anchor Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, terminal devices in an inactive state experience unnecessary power consumption and signaling overhead due to frequent connection setups for small data transmissions, especially when anchor relocation for context is required, leading to inefficiencies as the number of devices increases.
Innovation Solution
A method where a network device determines whether to relocate the anchor for a terminal device's context based on factors like data payload size and frequency of transmissions, allowing uplink data to be forwarded through the network device maintaining the context without relocation, thereby reducing signaling overhead and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a terminal device in inactive state establishes or reestablishes a connection with a network device for any downlink or uplink data transmission, then data transmission can be performed, but unnecessary power consumption and signaling overhead occur especially for small data packets
Solution Approach 1:
The patent extracts the essential function of data transmission from the full connection establishment process. By allowing small data transmissions in inactive state without complete connection setup, it separates the minimal necessary signaling from the full connection procedure, thereby reducing power consumption while maintaining data transmission capability.
Solution Approach 2:
Instead of performing full connection establishment (excessive action) for every small data transmission, the patent applies partial action by maintaining the device in inactive state with just enough signaling to handle small data packets. This avoids the overhead of complete connection setup while still enabling data transmission.
2Productivity
If a terminal device in inactive state establishes or reestablishes a connection with a network device for any downlink or uplink data, then data transmission is enabled, but signaling overhead increases especially for small and infrequent data packets
Solution Approach 1:
The patent extracts only the essential signaling elements needed for small data transmission from the complete connection establishment procedure. By removing unnecessary signaling steps that are redundant for small data packets, it reduces signaling overhead while preserving the ability to transmit data.
Solution Approach 2:
The patent applies partial signaling action for small data transmissions in inactive state, using only the minimum necessary signaling rather than full connection setup signaling. This reduces the amount of signaling overhead proportionally to the size and frequency of data transmissions.
3Adaptability or versatility
If anchor relocation for context is performed for terminal devices in inactive state, then data transmission can be supported, but network complexity and processing overhead increase
Solution Approach 1:
The patent applies local quality by differentiating the handling of terminal devices based on their state and data transmission requirements. For small data transmissions in inactive state, it uses a simplified approach without full anchor relocation, while maintaining the ability to perform anchor relocation when necessary for larger transmissions or connectivity requirements.

AI summary
Embodiments of the present disclosure relate to methods, devices, and medium for communication. A method for communication comprises in accordance with a determination that a terminal device in an inactive state requests a first network device for a transmission of uplink data, determining whether to relocate an anchor for a context of the terminal device from a second network device to the first network device, the second network device maintaining the context of the terminal device. The method further comprises in accordance with a determination of non-relocation of the anchor for the context of the terminal device, causing the uplink data to be forwarded to a destination via the second network device based on the maintained context of the terminal device.
