Mobile Terminal Connection Setup Using Default Reporting Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of requiring mobile terminals to read system information before sending connection requests introduces significant delays, as they are unable to contact the radio access network during this time, and similarly, sending other messages on a common transport channel before a dedicated physical channel is established poses challenges.
Innovation Solution
Allowing mobile terminals to send connection request messages or other messages on a common transport channel before reading system information, using a default reporting configuration to include measurement results like Received Signal Code Power and signal-to-interference ratio, without waiting for a reporting configuration from the radio access network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile terminals are required to read system information before sending connection requests, then the RAN can obtain accurate cell reporting information for connection setup, but significant delays occur in the connection setup procedure
Solution Approach 1:
The mobile terminal performs measurements on access entities and stores measurement results in advance, before receiving the reporting configuration from the RAN. When the RAN later requests cell reporting information, the terminal can immediately provide pre-collected measurement data without needing to wait to perform measurements after receiving the configuration, thus eliminating the delay while maintaining information accuracy.
2Speed
If mobile terminals send messages on common transport channels before dedicated physical channels are established, then access speed is improved, but the terminal cannot obtain reporting configuration information from the RAN
Solution Approach 1:
The terminal performs measurements and stores results before establishing the dedicated physical channel and receiving the reporting configuration. This allows the terminal to send messages with cell reporting information immediately on the common transport channel, achieving fast access while the configuration information is obtained later through the subsequent dedicated channel establishment.
Solution Approach 2:
The measurement results act as an intermediary that bridges the gap between the terminal's ability to send messages quickly on common channels and the RAN's need for configured reporting parameters. The terminal uses pre-collected measurement data as a substitute for the尚未received configuration information, enabling early message transmission that would otherwise be impossible.
3Reliability
If mobile terminals wait for reporting configuration from the RAN before reporting cell information, then the RAN can optimize connection setup parameters, but the overall procedure becomes slower
Solution Approach 1:
The terminal prepares measurement results in advance before the RAN sends the reporting configuration. This allows the terminal to immediately report cell information upon receiving the configuration, enabling the RAN to optimize connection parameters without causing delays, thus maintaining both reliability and productivity.

AI summary
In a Communications system a message is sent from a mobile terminal to a radio access network on a common transport channel, the message comprising information. associated with one or more access entities of the radio access network. The information which is sent to the radio access network is based on a default reporting configuration stored in the mobile terminal.
