Multi-SIM RF Path Allocation for Paging Collision Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-SIM wireless communication systems, simultaneous use of multiple SIMs often results in periodic suspension of ongoing calls due to paging collisions, leading to degradation of communication quality and loss of information, as existing technologies fail to manage RF resources effectively between different network connections.
Innovation Solution
A method and device for simultaneous reception in multi-SIM wireless communication systems, which predicts and manages collisions by allocating RF paths to each SIM, allowing for concurrent processing of paging signals without suspending communications, using a conflict handler to determine if simultaneous reception is possible based on hardware configuration and RF resource availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple SIMs share a single RF resource in a multi-SIM wireless communication system, then device complexity is reduced, but communication reliability deteriorates due to periodic suspension of ongoing calls when paging collisions occur
Solution Approach 1:
The patent segments the RF resource into multiple independent RF paths (first RF path and second RF path) that can operate simultaneously and independently. Each SIM can be assigned to a separate RF path, allowing concurrent processing of paging signals without mutual interference or suspension, thereby resolving the contradiction between device simplicity and communication reliability.
Solution Approach 2:
The patent transitions from a single-dimension RF resource sharing model to a multi-dimensional model by introducing multiple RF paths that operate in parallel. This dimensional expansion allows the system to handle multiple SIMs simultaneously without requiring complex time-division multiplexing, maintaining reliability while avoiding excessive complexity.
2Device complexity
If multiple protocol stacks mutually exclusively use a single RF resource, then device complexity is reduced, but productivity deteriorates due to suspension of wireless communication during paging operations
Solution Approach 1:
The patent segments the RF resource into multiple independent RF paths, allowing each protocol stack to utilize dedicated RF resources simultaneously. This eliminates the need for mutual exclusion and periodic suspension, enabling continuous communication operations across multiple SIMs without compromising productivity.
Solution Approach 2:
By providing multiple RF paths that can operate concurrently, the patent ensures continuous useful action for all protocol stacks. Each SIM can maintain ongoing communications without interruption while others perform paging operations, eliminating periodic suspensions and maintaining constant productivity.
3Ease of manufacture
If a single RF resource is shared between multiple SIMs, then manufacturing cost is reduced, but loss of information occurs due to periodic suspension and degradation of communication quality
Solution Approach 1:
The patent segments the RF resource into multiple independent RF paths, allowing each SIM to have dedicated RF resources for critical operations. This prevents information loss by ensuring that paging operations on one SIM do not interrupt or corrupt ongoing communications on other SIMs, while still using the same physical device components.
Solution Approach 2:
The patent introduces a new dimension of RF path separation that allows simultaneous independent operations. This dimensional change prevents information loss by providing parallel execution paths, eliminating the need to suspend communications and ensuring data integrity across all SIMs without requiring additional hardware beyond standard multi-SIM device components.

AI summary
Disclosed are methods and devices for multi-Subscriber Identify Module (SIM) wireless communication. In an embodiment, a method includes establishing a window for at least receiving paging in an idle state of a first wireless communication associated with a first SIM. A prediction is made, based on the window, of a collision or non-collision between the paging and a second wireless communication associated with a second SIM. It is then determined, in response to a collision prediction, whether a simultaneous reception of the paging and the second wireless communication is possible through use of different respective carriers, if so, respective radio frequency (RF) paths are allocated to the paging and the second wireless communication, where the allocated RF paths correspond to the different respective carriers.
