Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, conflicts between configured multi-sim gaps lead to resource wastage and reduced system throughput due to the existence of non-usable or conflicting multi-sim gaps.
Innovation Solution
A communication method and apparatus that allows a terminal device to send messages indicating conflicting time units, enabling the network device to determine and configure resource allocation based on these indications, ensuring efficient retention or discard of these units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device requests the network device to configure multiple multi-sim gaps, then the terminal device can perform more operations (such as paging reception and measurement), but conflicts arise between the gaps causing resource wastage and reduced system throughput
Solution Approach 1:
The terminal device performs preliminary action by indicating in advance which time units it expects to retain and which to discard before the network device configures the multi-sim gaps. This allows the network device to pre-determine the configuration without causing conflicts, thereby maintaining operation capability while avoiding resource wastage from conflicting gaps.
Solution Approach 2:
The terminal device provides feedback information (first indication information) to the network device about its preferences for retaining or discarding specific time units. This feedback mechanism enables the network device to adjust the multi-sim gap configuration accordingly, resolving conflicts and optimizing system throughput while preserving necessary operations.
2Ease of operation
If the network device configures multiple multi-sim gaps without considering conflicts, then the terminal device can request expected time units, but conflicting gaps cannot be used simultaneously causing resource waste
Solution Approach 1:
The terminal device indicates in advance which time units it expects to retain and which to discard before the network device finalizes the configuration. This preliminary indication allows the network device to avoid configuring conflicting gaps that would waste resources, while still allowing the terminal device to request its expected time units.
Solution Approach 2:
The network device changes the configuration parameters (multi-sim gap settings) based on the terminal device's indication information. By adjusting which time units are retained or discarded according to the terminal's preferences, the system avoids resource wastage from unusable conflicting gaps while maintaining ease of operation.
3Reliability
If the terminal device indicates to retain all conflicting time units, then the terminal device maintains its expected operations, but the network device cannot configure usable gaps leading to reduced system throughput
Solution Approach 1:
Instead of requiring the terminal device to indicate all conflicting time units must be retained, the system allows partial retention based on actual usability. The terminal device can indicate its preferences, but the network device has the flexibility to configure only the usable gaps, achieving a balance between operation reliability and system throughput.
Solution Approach 2:
The terminal device provides feedback about its operational needs, but the network device uses this feedback to determine the actual usable gaps. This feedback mechanism allows the system to optimize system throughput by configuring only usable gaps while still ensuring the terminal device can perform its necessary operations.
4Productivity
If the network device discards conflicting multi-sim gaps, then system throughput is improved, but the terminal device loses expected operations (such as paging reception or measurement)
Solution Approach 1:
The terminal device performs preliminary action by indicating in advance which time units it needs for critical operations. This allows the network device to retain only the necessary gaps while discarding conflicting ones, improving system throughput while preserving essential terminal device operations.
Solution Approach 2:
The network device applies different quality treatment to different time units based on the terminal device's indications. Critical operations are retained with higher priority, while less critical or conflicting gaps are discarded. This local differentiation improves system throughput without compromising essential operation capabilities.

AI summary
This application provides a communication method and apparatus. The method includes: A terminal device sends a first message to a network device, where the first message indicates a plurality of time units expected by the terminal device, the plurality of time units include M conflicting time units, and M is an integer greater than or equal to 2. The first message includes first indication information, and the first indication information indicates to retain a part of the M time units, or the first indication information indicates to retain all of the M time units. According to the method disclosed in this application, whether the first indication information exists indicates to the network device that all or a part of the conflicting time units are to be retained, to avoid discarding of a time unit that can be used, and avoid a waste of resources and a reduction in a system throughput caused by existence of a time unit that cannot be used.
