Priority-Based Band Capability Messaging for Faster 5G Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of frequency bands supported by user equipment (UE) has led to inefficient communication due to the segmentation of band combinations, resulting in prolonged connection times and resource wastage, particularly in 5G networks, as operators constrain message sizes to adhere to standards, leading to resource inefficiencies and complex connection setups.
Innovation Solution
Implementing a priority-based capability messaging system where UE transmits band capabilities in priority order, with the network allocating and prioritizing frequency band groups, reducing the need for extensive initial message transmission and optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE sends all band combinations in the capability message, then the network can utilize all available bands, but the message size exceeds standard constraints and causes resource inefficiency
Solution Approach 1:
The capability message is segmented into multiple parts: a first capability message sent during initial connection containing essential band information, and a second capability message sent later containing additional band combinations. This segmentation allows the network to gradually acquire complete band information while adhering to message size constraints during critical connection phases.
Solution Approach 2:
The UE performs preliminary action by sending a reduced set of essential band combinations in the first capability message during initial connection setup. This preliminary transmission enables the network to establish connection using critical band information, while the complete band capability set is transmitted later when resource constraints are less critical.
2Adaptability or versatility
If the UE sends all band combinations in segments, then all band combinations can be utilized, but the connection setup time increases
Solution Approach 1:
The capability information is divided into two segments transmitted at different times: essential band combinations are sent immediately in the first message to enable rapid connection setup, while additional band combinations are sent in a second message later. This temporal segmentation resolves the conflict between complete band utilization and fast connection establishment.
Solution Approach 2:
The UE performs partial action by transmitting only the most essential band combinations in the first capability message, which is sufficient for initial connection setup. The complete set of band combinations is transmitted later in the second message, ensuring that connection establishment is not delayed by the transmission of all band information.
3Loss of information
If the UE sends all band combinations, then the network has complete information, but the complexity for both UE and network during connection setup increases
Solution Approach 1:
The capability messaging process is segmented into two distinct phases: initial connection setup using a first capability message with essential band information, and a subsequent phase using a second capability message with complete band information. This segmentation reduces the processing complexity during critical connection setup while ensuring complete information is eventually available.
Solution Approach 2:
The network performs preliminary action by establishing connection using the first capability message before processing the complete band information from the second message. This preliminary connection establishment simplifies the initial setup process, while the complete band capability information is integrated later when the connection is already established.
4Loss of information
If the UE transmits complete band information over-the-air, then the network has full band capabilities, but radio resource utilization increases
Solution Approach 1:
The transmission of band capability information is segmented into two separate messages sent at different times and under different resource constraints. The first capability message transmits essential band information using minimal radio resources during initial connection, while the second message transmits additional band information when radio resource availability is less critical.
Solution Approach 2:
The UE performs partial action by transmitting only essential band combinations in the first message, which is sufficient for initial network access. The remaining band combination information is transmitted in a second message, reducing the immediate radio resource consumption during critical connection establishment while ensuring complete information is eventually transmitted.
