Transmission Bearer Configuration for CCCH and SRB1
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP protocol does not provide a method to configure transmission bearers for the common control channel (CCCH) and signal radio bearer 1 (SRB1) under the strengthened connection mode common status, leading to indiscriminate behavior by the base station when prioritizing data transmission.
Innovation Solution
A method where the radio network controller informs the base station of the transmission bearer identifier for CCCH and SRB1 through signaling, allowing them to correspond to the same or different identifiers, and returns initial flow distribution information, ensuring consistent channel cognition between the radio network controller and base station for accurate data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the CCCH and SRB1 use the transmission bearer associated with any one configured media access flow, then the base station behavior becomes indiscriminative, but this approach simplifies the configuration process
Solution Approach 1:
The patent segments the transmission bearer configuration by separately defining transmission bearers for CCCH and SRB1, rather than using a single shared bearer. This segmentation allows prioritization of control channel data over user data, ensuring reliable transmission while maintaining manageable configuration through structured identifier assignment.
2Device complexity
If no special transmission bearer is configured for CCCH and SRB1, then the configuration process is simplified, but the base station cannot properly prioritize control channel data
Solution Approach 1:
The patent applies local quality by assigning specific transmission bearer identifiers to CCCH and SRB1, enabling differentiated treatment of control channel data compared to user data. This allows the base station to prioritize control channel transmission locally within the MAC layer processing, improving overall transmission efficiency without requiring system-wide complexity changes.

AI summary
It is disclosed a method for configuring transmission bearer under common status, comprising: radio network controller informs via a signaling a base station the transmission bearer identifier corresponding to the CCCH and SRB1 of the cell governed by the base station; the base station obtains the transmission bearer identifier from the signaling, and returns the corresponding transmission bearer identifier in a response message. With the above solution of the present invention, it is assured that the radio network controller and the base have consistent cognition about the sending and receiving channels, so as to guarantee the UE receives the data on the CCCH and SRB1 correctly.
