Mobile Terminal Data Conflict Resolution via Time Slot Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals based on GSM technology can only receive one data block at a time due to a single radiofrequency transceiver module, leading to discarded data blocks and reduced phone connection and cell switching rates.
Innovation Solution
A method where the mobile terminal determines non-adjacent time slots for receiving data blocks within a frame, allowing multiple data blocks to be received sequentially based on their time slot relationships, thereby reducing discard rates and improving connection and switching rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile terminal receives data blocks from multiple cells simultaneously, then the phone connection rate and cell switching rate improve, but the single RF transceiver module cannot handle concurrent receptions, leading to data block discards
Solution Approach 1:
The frame structure is segmented into multiple time slots, and data blocks are assigned to specific non-adjacent time slots. This segmentation allows the single RF transceiver to handle multiple data blocks sequentially without collision, resolving the contradiction between receiving multiple data blocks and the single transceiver limitation
Solution Approach 2:
The system dynamically adjusts the time slot allocation and switching between different cells based on the reception schedule. The RF transceiver dynamically switches between cells at different time slots, enabling flexible handling of multiple data blocks while maintaining reliable reception
2Device complexity
If the mobile terminal receives data blocks sequentially from different cells, then the single RF transceiver module can handle the reception, but data blocks from lower priority cells are discarded, reducing the phone connection rate
Solution Approach 1:
The system introduces the time dimension by allocating data blocks to different time slots within a frame. Instead of competing for the same time resource, data blocks from multiple cells are separated in time, allowing the single RF transceiver to receive multiple data blocks without discarding any, thus improving phone connection rate while maintaining simple hardware
3Ease of operation
If the mobile terminal discards data blocks from non-highest priority cells, then the single RF transceiver can focus on one cell at a time, but system information updates are delayed and cell switching becomes slow
Solution Approach 1:
The system performs preliminary scheduling of data block receptions by assigning specific time slots to different cells before actual reception. This preliminary arrangement ensures that all necessary data blocks are received in advance without conflicts, preventing delays in system information updates and enabling faster cell switching

AI summary
The invention provides a method for resolving data conflicts and a mobile communication terminal. The embodiment about the method of the invention includes: a mobile terminal determining a time slot in a frame i for receiving a first data block; if a second data block needs to be received in the frame i, the mobile terminal determining a relationship between the time slot for receiving the first data block and a time slot for receiving the second data block; and if the time slots for receiving the first data block and the second data block are not the same and not adjacent, the mobile terminal receiving the first data block and the second data block sequentially according to the time slots in the frame i. The embodiment of the invention further provides a mobile terminal for implementing the method described above. The invention could receive multiple data blocks in a frame i and decrease the number of data blocks being discarded.
