5G Handover Control Based on Device State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G communication system, especially when using the FR2 frequency band, electronic devices experience increased power consumption due to high path loss and reflection, and current handover mechanisms do not consider the device's state, leading to unnecessary connection to base stations that support FR2 signals, thereby increasing power usage.
Innovation Solution
An electronic device equipped with a communication processor and an application processor that identifies the type of service and the device's state, allowing it to prevent or release connections to nodes supporting high frequency bands based on designated conditions, thereby reducing power consumption.

Engineering Contradiction Analysis
1Speed
If the electronic device connects to a base station supporting FR2 signal to achieve high data transmission rate, then the data transmission speed is improved, but the power consumption is increased
Solution Approach 1:
The patent implements dynamic handover decision-making by continuously monitoring device states (battery level, temperature, service type) and adjusting connection decisions accordingly. The handover determination unit dynamically selects target base stations based on real-time conditions, switching between FR1 and FR2 connections adaptively rather than using a fixed connection strategy.
Solution Approach 2:
The patent changes the parameters governing handover decisions by introducing multiple device state parameters (battery level, temperature, service type) that influence connection choices. The system modifies handover behavior by adjusting which parameters are prioritized based on current device conditions, thereby optimizing the balance between data rate and power consumption.
2Productivity
If the cellular network system performs handover based on network control only, then the network resource allocation is optimized, but the device state requirements are not met, leading to unnecessary power consumption
Solution Approach 1:
The patent implements a feedback mechanism where the electronic device continuously reports its state (battery level, temperature, service type) to the network, and the network adjusts handover decisions based on this feedback. The handover determination unit uses real-time device state information to make informed connection decisions, creating a closed-loop control system that balances network efficiency with device power consumption.
Solution Approach 2:
The system transitions from static network-controlled handover to dynamic joint optimization by incorporating real-time device state monitoring. The handover determination unit dynamically adjusts connection decisions based on changing device conditions, enabling the system to adaptively balance network resource allocation with device power consumption requirements.
3Reliability
If the electronic device connects to FR2 base station to support high frequency band services, then the service quality is improved, but the connection causes unnecessary power consumption when device state does not satisfy designated condition
Solution Approach 1:
The patent introduces service type as a key parameter in handover decisions, with different service types (eMBB, URLLC, mMTC) having different designated conditions. The system changes connection parameters based on service requirements and device state, allowing high-quality service delivery only when device conditions (battery level, temperature) are appropriate, thereby avoiding unnecessary power consumption.
Solution Approach 2:
The system dynamically adjusts connection behavior by continuously evaluating device state against service-specific designated conditions. The handover determination unit adaptively modifies connection decisions based on real-time device conditions, ensuring that high-quality FR2 connections are established only when device state supports such consumption, while maintaining appropriate service quality.

AI summary
An example electronic device includes a communication processor for establishing a cellular communication with a first node supporting a first frequency band or a second node supporting a second frequency band; an application processor; and memory. The memory can store instructions which, when executed, control the communication processor such that: the communication processor confirms a service type performed by the cellular communication; the application processor confirms whether or not the state of the electronic device satisfies a predetermined condition set differently in accordance with the service type; and the application processor blocks a connection with the second node and/or releases the connection with the second node, in response to confirming that the state of the electronic device does not satisfy the predetermined condition.
