Selective Channel Reset via Reset Flag in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as UMTS, face inefficiencies in channel reset operations, where all active MAC-HS channels must be reset when one is transferred, leading to unnecessary resets, performance penalties, data loss, bandwidth waste, and battery life loss.
Innovation Solution
The method involves determining superior communication properties of a candidate cell over a serving cell, adding a reset flag to a channel reconfiguration message, and instructing the UE to reset a subset of channels, rather than all, to facilitate selective channel reset and transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all MAC-HS channels are reset when one is transferred, then channel transfer can be completed, but unnecessary resets occur causing performance penalties, data loss, bandwidth waste, and battery life loss
Solution Approach 1:
The patent segments the channel reset operation by introducing a reset indicator flag that can be selectively applied to individual MAC-HS channels. Instead of resetting all channels uniformly, the system now can identify and reset only the specific channel being transferred, while leaving other active channels untouched. This segmentation resolves the contradiction by eliminating unnecessary resets of other channels, thereby conserving battery life and avoiding performance penalties while still ensuring reliable transfer of the target channel.
2Reliability
If all MAC-HS channels are reset when one is transferred, then channel transfer can be completed, but performance penalties and data loss occur
Solution Approach 1:
The patent introduces granular control over channel reset operations through per-channel reset indicators. This allows the system to reset only the specific MAC-HS channel being transferred while preserving other active channels and their associated data buffers. By segmenting the reset operation to affect only the necessary channel, the patent eliminates unnecessary data loss and performance penalties that would otherwise occur when resetting all channels, while still ensuring the transferred channel is properly reset for reliable operation.
3Reliability
If all MAC-HS channels are reset when one is transferred, then channel transfer can be completed, but bandwidth waste occurs
Solution Approach 1:
The patent implements selective channel reset by introducing reset indicator flags that can be independently set for each MAC-HS channel. This segmentation allows the system to reset only the specific channel being transferred while maintaining other active channels without interruption. By avoiding unnecessary resets of other channels, the patent prevents bandwidth waste that would occur during redundant reset operations, while still ensuring reliable transfer of the target channel through proper reset procedures.
4Reliability
If all MAC-HS channels are reset when one is transferred, then channel transfer can be completed, but the system complexity increases due to inability to selectively reset subsets
Solution Approach 1:
The patent applies local quality by introducing per-channel reset indicators that allow differential treatment of individual MAC-HS channels. Instead of a uniform reset approach, the system can now apply reset operations locally to only those channels that require it. This local quality approach actually reduces system complexity by providing clear, channel-specific control signals that eliminate the need for complex global reset management, while still ensuring reliable transfer operations.

AI summary
The present disclosure presents methods and apparatuses for selective channel reset. For example, the disclosure describes example methods that may include determining that a candidate cell exhibits superior communication properties on a carrier than does a serving cell. In an aspect, this carrier may correspond to an active serving cell channel. The example methods may also include adding a reset flag to a channel reconfiguration message based on the determining, where the reset flag instructs a user equipment to reset a subset of a set of channels associated with the serving cell and the subset includes the channel. Furthermore, example methods may include transmitting the channel reconfiguration message, for example, to a user equipment. Thus, a specified subset of channels associated with the user equipment may be reset, which reduces the signaling load, complexity, and power drain associated with legacy channel reset methods and apparatuses.
