Single Radio Block Transmission Without Temporary Block Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face capacity challenges due to the extensive control signalling and header information required for Machine Type Communication (MTC) devices, which hampers their ability to support a large number of MTC devices alongside traditional devices.
Innovation Solution
The solution involves sending application layer messages within a single radio block without establishing a temporary block flow (TBF), reducing the need for extensive control signalling and header information, and using an intermediate node to allocate radio resources for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless communication procedures are used for MTC devices, then reliable data transmission is achieved, but the amount of control signalling and header information increases significantly
Solution Approach 1:
The patent extracts and removes the Temporary Block Flow (TBF) establishment procedure from the traditional data transmission process. By eliminating this intermediate step, the patent reduces the amount of control signaling and header information required while maintaining transmission reliability through direct resource allocation from the base station to the MTC device.
Solution Approach 2:
The patent implements preliminary resource allocation where the base station pre-allocates radio resources to MTC devices before data transmission begins. This preliminary action eliminates the need for TBF establishment during actual data transfer, reducing control signaling overhead while ensuring reliable transmission through pre-configured resources.
2Adaptability or versatility
If elaborate procedures with extensive control signalling are used, then robust handling of non-MTC devices is achieved, but network capacity for MTC devices is reduced
Solution Approach 1:
The patent applies local quality by creating a specialized transmission mode specifically for MTC devices that differs from the traditional mode used by non-MTC devices. The single-block transmission procedure is locally optimized for MTC characteristics (small, infrequent data packets) while maintaining compatibility with existing network infrastructure and non-MTC device procedures.
Solution Approach 2:
The patent segments the data transmission process into two distinct modes: traditional multi-block transmission with TBF for non-MTC devices, and optimized single-block transmission without TBF for MTC devices. This segmentation allows the network to handle different device types with appropriate procedures, increasing overall network capacity while maintaining adaptability.

AI summary
Embodiments herein advantageously reduce the amount of control signalling and header information that must accompany an application layer message when transporting that message from a wireless device to a supporting application server via an intermediate node. To do so, the wireless device prepares a single radio block that includes the application layer message and an indication that the single radio block contains the entire application layer message. The device then sends a control message to the intermediate node that requests allocation of radio resources for sending the single radio block without establishing a temporary block flow (TBF). The device finally sends the single radio block using the allocated resources, without a TBF. Upon receiving the block, the intermediate node determines, based on the indication within the block, whether or not the block contains an entire application layer message. If so, the intermediate node forwards that application layer message towards the application server.
