UE Multi-Connectivity Restriction via Mapping Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-connectivity technologies in user equipment (UE) are not frequently utilized due to the lack of implementation by service providers and the limited adoption of network protocols like MPTCP, MP-QUIC, and MPDCCP, which restricts the ability to leverage multiple access modes for enhanced reliability and speed, especially for services that require single access modes.
Innovation Solution
A method is introduced where a mapping table is stored on the UE to assign specific single access modes to services, allowing the UE to redirect or schedule data traffic through a bypass entity or multipath scheduler to the appropriate communication link, enabling restriction of multi-connectivity functionality and ensuring services are accessible only via the required single access mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-connectivity functionality is enabled in UE, then reliability and speed are improved, but device complexity and protocol implementation requirements increase
Solution Approach 1:
The patent introduces a multi-connectivity entity as an intermediary component within the UE that manages connections to multiple access networks. This entity acts as a mediator between the application layer and the physical communication interfaces, handling the complexity of multi-connectivity management internally while presenting a simplified interface to applications. The entity maintains mapping tables and performs automated access selection, thereby improving reliability through diverse path availability without requiring complex protocol implementations at the application level.
2Productivity
If services are restricted to single access mode, then resource efficiency and data throughput are improved, but adaptability and versatility are reduced
Solution Approach 1:
The patent implements dynamic access mode assignment through mapping tables that can be configured based on service requirements. The system allows services to be dynamically assigned to specific access modes (single or multi-connectivity) based on their characteristics, performance requirements, and current network conditions. This dynamic configuration enables the system to optimize for data throughput when single access is sufficient while maintaining adaptability to switch to multi-connectivity modes when services require higher reliability or bandwidth, thus resolving the contradiction between productivity and adaptability.
3Reliability
If multi-connectivity is implemented, then redundancy and failover capability are improved, but ease of operation and service compatibility are reduced
Solution Approach 1:
The patent implements self-service mechanisms where the multi-connectivity entity automatically manages service configuration without requiring manual intervention. The system includes automated service discovery functionality that identifies services requiring multi-connectivity support and configures appropriate access modes based on pre-defined policies and mapping tables. This self-configuration capability provides redundancy and failover capability while maintaining ease of operation, as the system adapts automatically without requiring users to manually configure complex multi-connectivity parameters for each service.

AI summary
A method for restricting multi-connectivity functionality of a user equipment (UE) includes: storing a mapping table on a memory of the UE, wherein the mapping table provides assignment information about a respective single access mode assigned to a service requestable by the UE, wherein the respective single access mode is one of multiple access modes; receiving service information about a requested service via a network interface of the UE; comparing, by a process of the UE, the service information to entries of the mapping table, and selecting a single access mode assigned to the requested service; wherein the multi-connectivity functionality of the UE is restricted by: a bypass entity redirecting data traffic associated with the requested service directly to the selected single access mode; or a multipath scheduler scheduling data traffic associated with the requested service to a communication link that corresponds to the selected single access mode.
