Access Barring Configuration Using Extended Logical Channel IDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The LTE system lacks a logical channel identifier to identify the number of radio bearers supported by the next-generation mobile communication system, preventing it from supporting the necessary number of radio bearers when connected to an NR core network.
Innovation Solution
A method is proposed to configure an additional logical channel identifier in the core network of a next-generation mobile communication system, enabling support for an extended number of radio bearers even when an LTE wireless network is connected to an NR core network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the LTE system uses the existing logical channel identifier structure, then the system maintains compatibility with current LTE specifications, but it cannot support the extended number of radio bearers required by next-generation mobile communication systems
Solution Approach 1:
The patent extends the logical channel identifier from 5 bits to 6 bits, adding another dimension to the identifier space. This allows the system to support up to 64 logical channels instead of the previous 32, enabling support for extended number of radio bearers while maintaining the same identifier structure type
Solution Approach 2:
The patent changes the parameter of logical channel identifier length from 5 bits to 6 bits. This parameter change doubles the identifier space, allowing the LTE system to support the extended number of radio bearers required by next-generation mobile communication systems
2Adaptability or versatility
If the system configures additional logical channel identifiers in the core network, then it can support more radio bearers when connected to NR core network, but it increases the complexity of access control configuration
Solution Approach 1:
The patent makes the logical channel identifier structure universal by designing it to work with both LTE and NR core networks. The extended 6-bit identifier can accommodate the requirements of next-generation systems while maintaining compatibility with existing LTE infrastructure, enabling multi-functionality across different network types
3Productivity
If the LTE system supports more radio bearers through extended logical channel identifiers, then it meets the demands of next-generation communication, but it requires modification of the current identifier structure
Solution Approach 1:
By adding one more bit dimension to the logical channel identifier (from 5 to 6 bits), the system doubles its identifier capacity from 32 to 64 channels. This dimensional extension enables support for more radio bearers and higher data transmission capacity without fundamentally changing the identifier structure type

AI summary
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure also relates to a method and an apparatus for configuring barring configuration information of a user equipment (UE). A method of a UE according to the disclosure comprises: receiving a system information block (SIB) including barring information per access category; identifying an access category relating to an access attempt; identifying an index included in barring information corresponding to the access category; and determining whether to bar the access attempt based on access control information indicated by the index.
