Radio Capability Update for Relay Access QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices face challenges with battery life and antenna design due to their small size, leading to increased power consumption and reduced network access efficiency, and existing solutions fail to provide optimal Quality of Service (QoS) when switching between direct network access and relay terminal access without notifying the network of capability changes.
Innovation Solution
A method for obtaining radio capability information of a terminal, core network entity, and base station, involving messages like S1-AP initial context setup requests and capability updates, to determine available QoS by sharing connection manner and identification information between terminals, enabling optimal network resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wearable device directly accesses base station network, then network communication capability is improved, but power consumption increases and standby time decreases
Solution Approach 1:
The patent introduces a relay terminal as an intermediary device between the wearable device and the base station. The wearable device communicates through the relay terminal instead of directly with the base station, reducing power consumption while maintaining network connectivity. The relay terminal forwards messages and capability information between the wearable device and the network.
2Use of energy by moving object
If wearable device uses relay terminal for network access, then power consumption is reduced, but network access efficiency decreases
Solution Approach 1:
The patent implements preliminary action by having the wearable device notify the network about its radio capability information and access mode changes in advance. The device sends capability information including relay terminal identification and connection manner before actual data transmission, enabling the network to pre-configure optimal QoS parameters and transmission rates, thus avoiding delays during actual communication.
3Loss of energy
If network does not receive capability update notification, then signaling overhead is reduced, but QoS optimization is lost
Solution Approach 1:
The patent implements a dynamic capability notification mechanism where the wearable device actively updates the network about its access mode changes and radio capability information. The device determines whether it is in direct access mode or relay access mode and sends appropriate capability information to the network, enabling the network to dynamically adjust QoS parameters based on the current access state.
4Adaptability or versatility
If wearable device sends detailed capability information, then network can provide optimal QoS, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential capability information needed for QoS optimization and sends it to the network. The wearable device sends specific elements such as relay terminal identification (C-RNTI or S-TMSI), connection manner (D2D, Bluetooth, WiFi), and access mode indicators, rather than transmitting complete device specifications. This selective information transmission achieves QoS optimization while minimizing signaling overhead.

AI summary
Embodiments of the present invention relate to a method for obtaining radio capability information of a terminal, a core network entity, a base station, and a terminal. When a first terminal changes from a first communication path for the first terminal to directly access a network to a second communication path for the first terminal to access the network by using a second terminal, the first terminal receives a first message that is sent by a base station to obtain radio capability information of the first terminal; and then sends the radio capability information of the first terminal to the base station, where the radio capability information includes information about a manner of connection between the first terminal and the second terminal and identification information of the second terminal.
