Fast Return Measurement Prioritization After Voice Call Release

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The success rate of fast return measurement tasks in terminals is low, and the time delay is large due to the existence of other measurement tasks, exceeding the terminal's capacity limits.

Innovation Solution

A method and apparatus that determine the data service state during a voice call, perform RRC release when no data service is detected, and prioritize and execute only the fast return measurement task, with optional blind redirection based on channel and interference conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple measurement tasks are executed simultaneously in the terminal, then the measurement coverage is improved, but the terminal exceeds its upper limit of supported measurement objects and cannot execute the fast return measurement task

Engineering Contradiction:

Improvemeasurement coverageVSAvoidfast return execution success rate

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent dynamically adjusts the measurement task configuration based on service state. When voice service ends, the system determines whether to keep or release other measurement tasks based on data service state, making the measurement object set dynamic rather than static to resolve the conflict between coverage and execution success rate

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent performs preliminary determination of data service state before the fast return measurement task is executed. By evaluating the data service state in advance (before the measurement task execution), the system can proactively configure the appropriate measurement task set, ensuring the fast return task can be executed successfully

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If other measurement tasks are executed simultaneously with the fast return measurement task, then the measurement coverage is improved, but the time delay of fast return increases

Engineering Contradiction:

Improvemeasurement coverageVSAvoidfast return time delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements dynamic adjustment of measurement tasks based on real-time service state. When data service is detected, the system keeps other measurement tasks; when no data service is detected, the system releases them to reduce interference and time delay for fast return execution

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent performs preliminary evaluation of data service state to determine in advance whether to maintain or release other measurement tasks. This preliminary action prevents time delay by proactively configuring the optimal measurement task set before the fast return task needs to execute

Inventive Principle:

Principle #10Preliminary action

AI summary

A method and apparatus for processing a fast return measurement task, a storage medium, and an electronic device are provided. The method includes: determining a data service state of a terminal during a voice call; in response to determining that, when the voice call ends, the data service state is that there is no data service, performing Radio Resource Control (RRC) release on the terminal through an RRC release command; and in response to determining that the data service state is that there is data service, stopping executing other measurement tasks configured previously, and executing only the fast return measurement task on the terminal.
