Fast Transmission Indication for Small Data Packet Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data packet transmission procedures in communications technologies, particularly in Universal Mobile Telecommunications Systems (UMTS), are excessively long and inefficient, leading to delays in data transmission for small data packets used in services like email pushing, instant messaging, and machine-to-machine (MTC) services.
Innovation Solution
A method and apparatus that utilize fast transmission indications, such as access signatures, PRACH channelization codes, and E-RNTI, to simplify the data transmission process by indicating a fast transmission procedure, allowing the base station and RNC to bypass the establishment of multiple signaling channels, thereby improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing data packet transmission procedure is used, then the transmission is reliable and follows standard protocol, but the transmission delay increases and efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-configuring fast transmission resources and indications at the base station before actual data transmission occurs. The base station pre-allocates physical random access channel resources and configures fast transmission indication information, so that when small data packets need to be transmitted, the UE can immediately use these pre-prepared resources without going through the standard lengthy connection establishment procedure, thus reducing transmission delay while maintaining reliability
Solution Approach 2:
The patent segments the data transmission process by creating a separate fast transmission path for small data packets, distinct from the standard RRC connection establishment procedure. This segmentation allows small data packets to bypass the complex multi-step standard procedure and use a simplified dedicated path, reducing delay for this specific segment of traffic while preserving the reliability of the standard procedure for other traffic types
2Reliability
If the standard RRC connection establishment procedure is followed, then proper channel setup is ensured, but the transmission procedure becomes excessively long
Solution Approach 1:
The base station performs preliminary actions by pre-configuring fast transmission resources including physical random access channel resources and fast transmission indication information before any data transmission occurs. This advance preparation enables the UE to immediately transmit small data packets using pre-allocated resources without initiating the standard RRC connection establishment procedure, thereby significantly reducing transmission procedure length while maintaining channel setup reliability
Solution Approach 2:
The patent inverts the traditional approach by having the base station proactively configure and indicate fast transmission resources to the UE before the UE needs to send data, rather than waiting for the UE to request resources through the standard procedure. This inversion allows the network to control and optimize the transmission path in advance, reducing procedure length while ensuring proper channel setup
3Reliability
If multiple signaling channels are established for data transmission, then comprehensive control is achieved, but the procedure complexity increases
Solution Approach 1:
The patent extracts the essential control functions from the complex multi-channel RRC connection establishment procedure and consolidates them into a simplified fast transmission path. By taking out only the necessary control elements needed for small data packet transmission and removing unnecessary signaling steps, the procedure complexity is reduced while maintaining the essential control reliability needed for proper data transmission
