Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of large RRC messages in information transmission methods affects the transmission of subsequent RRC messages, leading to poor user experience.
Innovation Solution
The method involves segmenting RRC messages based on target information, incorporating identification information, and prioritizing transmission to allow for simultaneous or alternate sending of RRC message segments, utilizing different signaling radio bearers and considering receiving end capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large RRC message is transmitted by dividing into multiple segments and transmitting continuously, then the complete target information can be delivered, but the transmission of subsequent RRC messages is blocked and user experience deteriorates
Solution Approach 1:
The patent segments the large RRC message into multiple segments (first RRC message segment, second RRC message segment, etc.) and transmits them through different signaling radio bearers (SRBs). This allows parallel transmission of multiple segments simultaneously rather than sequential transmission, resolving the contradiction by maintaining reliability through complete segment delivery while improving productivity through concurrent transmission channels
Solution Approach 2:
The patent introduces a new dimension for transmission by using multiple signaling radio bearers (SRB1, SRB2, etc.) as separate transmission channels. Instead of transmitting segments sequentially on a single channel (one-dimensional), the system utilizes multiple parallel channels (multi-dimensional), allowing simultaneous transmission of different RRC message segments and subsequent messages without blocking
2Device complexity
If multiple RRC message segments are transmitted sequentially on the same bearer, then buffer space can be managed simply, but transmission time increases and user experience worsens
Solution Approach 1:
The patent divides the transmission task into multiple segments that can be transmitted in parallel across different SRBs. Each segment is independently managed with its own identification information, allowing the receiving end to reassemble them correctly. This segmentation enables simultaneous transmission rather than sequential processing, reducing transmission time while maintaining manageable buffer complexity through structured identification
Solution Approach 2:
The patent changes the transmission parameter from sequential single-channel transmission to parallel multi-channel transmission. By assigning different segments to different SRBs with varying priorities and capabilities, the system optimizes transmission time without significantly increasing buffer management complexity, as each bearer maintains its own transmission buffer independently

AI summary
This disclosure provides an information transmission method and apparatus. In the method, a transmitting end determines a plurality of radio resource control (RRC) message segmentations based on to-be-sent target information, where an RRC message segment in the plurality of RRC message segments includes partial information of the target information and at least one of the following: target identification information indicating the target information, RRC identification information indicating an RRC message to which the RRC message segment belongs, or segment identification information indicating the RRC message segment. The transmitting end sends the plurality of RRC message segments to a receiving end.
