Multimode Terminal Handover Using Adaptive Switching Delay

The patent applies dynamics by making the switching delay parameter adaptive rather than fixed. The terminal device dynamically adjusts the switching delay based on its movement speed: when moving at high speed, a longer delay is applied to prevent frequent switching due to signal fluctuations; when moving at low speed, a shorter delay is used to maintain sensitive response to signal quality changes. This dynamic adjustment resolves the contradiction between stability and sensitivity.

The patent changes the parameter of switching delay based on the terminal's movement speed. By introducing movement speed as a variable parameter, the system transitions from a static switching mechanism to a dynamic one where the delay parameter is continuously adjusted according to operational conditions, thereby resolving the trade-off between reducing switching frequency and maintaining switching sensitivity.

The system dynamically adjusts the switching delay based on movement speed conditions. When the terminal moves at high speed, the system automatically increases the switching delay to suppress frequent switching caused by rapid signal fluctuations, while maintaining sensitivity when moving at low speeds. This dynamic behavior prevents the harmful effect of frequent switching while preserving switching sensitivity when needed.

The switching delay parameter is changed according to the terminal's movement speed state. By introducing this parameter change mechanism, the system can selectively apply short delays for sensitive switching when appropriate (low speed) and long delays to prevent frequent switching when necessary (high speed), thereby resolving the contradiction between sensitivity and switching frequency stability.

The patent introduces movement speed as an intermediary parameter that mediates between signal quality metrics and switching decisions. The movement speed information acts as a filtering mechanism that prevents automatic switching when high speed causes signal fluctuations, thereby reducing frequent mode switching while maintaining automated decision-making capability for stable conditions.

The system changes the switching behavior parameter (switching delay) based on movement speed while maintaining automated switching decisions based on signal quality. This parameter adjustment prevents frequent switching caused by signal fluctuations during high-speed movement, thereby stabilizing mode switching while preserving automation.
