Modem Carrier Auto-Selection Algorithm for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing and sales processes for wireless communication devices are complicated by the need for specific configurations for each cellular carrier, leading to inventory challenges and consumer dissatisfaction when switching carriers, as devices are often not easily reconfigured for different carriers.
Innovation Solution
The implementation of an automated configuration system in access terminals that determines the carrier identity and selects the appropriate modem configuration from stored data to configure the communications interface, allowing seamless operation with different carriers without user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access terminals are manufactured and sold specifically configured for particular carriers, then the communications interface can be optimized for that carrier, but inventory complexity increases and consumers must visit physical locations to switch carriers
Solution Approach 1:
The access terminal is designed with a universal communications interface that can operate with multiple carriers through carrier aggregation. The system stores multiple modem configurations corresponding to different carriers and automatically selects the appropriate configuration based on the detected carrier, allowing a single device to replace multiple carrier-specific devices while maintaining optimized communication performance for each carrier
Solution Approach 2:
The modem configuration is made dynamic rather than fixed. The system automatically detects the active carrier and dynamically switches between different modem configurations stored in memory. This dynamic reconfiguration capability allows the terminal to adapt to different carriers without physical modification, resolving the contradiction between carrier-specific optimization and inventory simplicity
2Reliability
If access terminals are manufactured specifically for each carrier, then communication performance is optimized, but consumers experience dissatisfaction when switching carriers due to additional configuration steps
Solution Approach 1:
The terminal performs self-configuration when switching carriers. The system automatically detects the new carrier, selects the corresponding modem configuration from stored data, and applies the appropriate settings without requiring user intervention. This self-service capability maintains optimized communication performance while eliminating the need for consumers to visit physical locations or manually configure settings when switching carriers
Solution Approach 2:
Multiple modem configurations for different carriers are pre-stored in the terminal's memory during manufacturing. When a carrier switch occurs, the system already has the necessary configuration data available and can immediately switch between configurations without requiring real-time configuration generation or external assistance, thus maintaining both performance and ease of operation
3Reliability
If multiple access terminals with different carrier configurations are maintained, then each carrier can be served optimally, but excess inventory is created as it is not possible to know in advance which carriers will attract more consumers
Solution Approach 1:
A single access terminal is designed with multi-carrier capability, storing multiple modem configurations that correspond to different carriers. This universal design allows the terminal to serve multiple carriers optimally without requiring separate dedicated devices for each carrier, thereby reducing inventory quantity while maintaining carrier service quality
Solution Approach 2:
The terminal changes its operational parameters by switching between different modem configurations stored in memory. Instead of maintaining physically different devices for different carriers, the system achieves carrier-specific optimization by dynamically changing software/configuration parameters, thus reducing the quantity of devices needed in inventory while preserving carrier service quality

AI summary
Aspects of the present disclosure includes a method of performing enhanced auto-selection in a UE including initiating the UE having at least a first subscriber identify module (SIM) card and a second SIM card, obtaining a current ICCID associated with the first SIM card, obtaining, from a cache of the UE, a previous ICCID used in a previous connection to a previously identified carrier, determining whether the current ICCID matches the previous ICCID, in response to determining that the current ICCID does not match the previous ICCID, creating a new card information using data stored in the first SIM card, obtaining one or more selection policies, identifying a carrier based on the one or more selection policies, and connecting to the identified carrier using data stored in the second SIM card associated with the identified carrier.
