Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a WLAN carrier is added to transmit data between base station and user equipment, then data transmission capacity is improved, but service interruption occurs during configuration and activation
Solution Approach 1:
The base station performs preliminary actions by determining additional configuration of the WLAN carrier and transmitting configuration indication information to the user equipment before actual data transmission. The user equipment proactively attempts association with the WLAN termination using its identification information, preparing the transmission path in advance to minimize service interruption when the WLAN carrier is activated.
2Reliability
If frequency resources are exclusively secured by a service provider, then data transmission reliability is improved, but cost increases excessively
Solution Approach 1:
The patent merges the licensed frequency resources of the base station with the unlicensed frequency resources of the WLAN carrier. This combination allows the service provider to utilize both exclusively secured frequency bands and shared unlicensed bands, thereby maintaining data transmission reliability while reducing the need to exclusively secure additional frequency resources.
Solution Approach 2:
The system implements multi-functionality by enabling the user equipment to communicate through multiple carriers simultaneously - the original E-UTRAN carrier and the additional WLAN carrier. This allows the frequency resources to serve multiple purposes and multiple service providers, reducing the need for any single provider to exclusively secure all necessary frequency resources.
3Adaptability or versatility
If unlicensed frequency band is shared by multiple service providers, then resource utilization is improved, but data transmission reliability decreases
Solution Approach 1:
The patent segments the data transmission path into multiple independent carriers - the licensed E-UTRAN carrier and the unlicensed WLAN carrier. By dividing the transmission responsibilities across these separate carriers, the system can utilize shared unlicensed frequency resources while maintaining reliability through the segmented architecture, where failure on one carrier does not completely disrupt service.

AI summary
The provided is a method and apparatus for adding a WLAN carrier to an E-UTRAN carrier at a radio access network (RAN) level to transmit and receive data. The method may include: receiving, from a base station, additional configuration indication information for additionally configuring a WLAN carrier; additionally configuring the WLAN carrier on the basis of the additional configuration indicating information; and attempting WLAN associating through the WLAN carrier using UE identification information, wherein a WLAN end transmits confirmation information for the WLAN association of the UE to the base station.
