Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks, particularly EPS architecture, are inefficient in handling both low and high volumes of data due to the need for burdensome protocol modifications and excessive signaling messages, leading to increased power consumption and unsuitable transmission modes.
Innovation Solution
A method for dynamically selecting between data transport and signaling channels based on data volume, using an alert message to trigger a service request and determining the appropriate channel setup, allowing for flexible and reliable transmission mode selection without protocol changes, by calculating the total data volume until the service request is received or storing packets for a predetermined period.

Engineering Contradiction Analysis
1Productivity
If a data transport channel is set up for each terminal to transmit data, then data transmission capability is improved, but signaling message exchange increases and power consumption rises
Solution Approach 1:
The patent applies dynamics by making the channel selection adaptive and flexible. The network dynamically determines whether to use a data transport channel or signaling channel based on real-time assessment of data volume and terminal characteristics. This dynamic adaptation allows the system to optimize between transmission capability and power consumption by switching between channel modes rather than being fixed to one approach.
Solution Approach 2:
The patent changes the parameter of channel selection based on data volume thresholds and terminal characteristics. By monitoring parameters such as data packet size, number of packets, and terminal type, the system adjusts the transmission mode parameter - switching between data transport channel and signaling channel - to achieve optimal balance between productivity and energy consumption.
2Use of energy by moving object
If a signaling channel is used to transmit small volumes of data, then power consumption is reduced, but transmission efficiency decreases for large data volumes
Solution Approach 1:
The system dynamically switches between signaling channel and data transport channel based on real-time data volume assessment. For small data volumes, the signaling channel is used to minimize power consumption. When data volume exceeds thresholds, the system transitions to data transport channel to maximize transmission efficiency, thus dynamically optimizing the trade-off between energy consumption and productivity.
Solution Approach 2:
The patent changes the transmission mode parameter based on data volume parameters and terminal characteristics. By establishing threshold values for data volume and adjusting the channel selection parameter accordingly, the system ensures that signaling channel is used only when appropriate for low-power operation, while switching to data transport channel when high transmission efficiency is needed.
3Adaptability or versatility
If protocol modifications are introduced to handle different data volumes, then transmission flexibility is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by making the existing EPS architecture multi-functional. The signaling channel and data transport channel both coexist in the same network architecture, with the signaling channel capable of carrying both signaling messages and small data volumes. This multi-functionality eliminates the need for separate dedicated channels for different data types, thereby achieving transmission flexibility without proportionally increasing device complexity.
Solution Approach 2:
The patent segments the data transmission function into two distinct pathways: signaling channel for control messages and small data, data transport channel for bulk data. This segmentation allows each channel to be optimized for its specific purpose while maintaining overall system flexibility. The network entity manages both segments independently, choosing the appropriate segment based on data volume requirements.
4Speed
If the initial packet volume is used to determine transmission mode, then decision speed is improved, but accuracy of data volume assessment decreases
Solution Approach 1:
The patent applies preliminary action by establishing threshold values and assessment criteria before actual data transmission begins. The network entity pre-configures the decision-making framework with predefined volume thresholds and terminal characteristic categories, enabling rapid classification of data volumes during transmission. This preliminary preparation allows for both fast decision-making and accurate assessment by referencing pre-established benchmarks rather than performing complex real-time calculations.
Solution Approach 2:
The patent implements feedback mechanisms where the network entity continuously monitors data volume during transmission and adjusts the transmission mode accordingly. By receiving feedback about actual data volume and comparing it against thresholds, the system can correct initial assessments and switch transmission modes if needed, thereby improving both decision speed through iterative feedback and accuracy through continuous volume tracking.

AI summary
A method for transmitting downlink data from a mobile communication network to a mobile terminal. The method includes: transmitting, from a mobile terminal to a first network entity of the mobile communication network, a parameter indicating that the mobile terminal wishes to use signalling messages rather than a data transport channel for transmission of downlink data; and transmitting, from a second network entity of the mobile communication network to the mobile terminal, at least one signalling message in which downlink data received by a third network entity of the mobile communication network have been inserted.
