UE Capability Repository for Reduced Mobile Network Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing amount of data for user equipment (UE) capability messaging in mobile devices is becoming burdensome due to the complexity and overhead of network traffic.
Innovation Solution
Implementing a UE capability repository that stores associations between UE capabilities and identifiers, allowing UEs to send identifiers instead of full capability information, reducing network traffic by retrieving capabilities from the repository when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full UE capability information is transmitted repeatedly, then network reliability is improved, but network traffic increases and becomes burdensome
Solution Approach 1:
The UE capability information is segmented into two parts: a compact identifier that represents the capability set, and the full capability information stored in the repository. Instead of transmitting the entire capability information repeatedly, only the small identifier is transmitted over the air interface, while the full information is retrieved from the repository using this identifier.
Solution Approach 2:
A UE capability repository is introduced as an intermediary component that stores the mapping between identifiers and full UE capability information. The repository acts as a mediator between the network and UE, allowing the network to retrieve full capability information without requiring repeated transmissions from the UE, thus reducing network traffic while maintaining reliability.
2Quantity of substance
If UE capability information is stored and reused, then network traffic is reduced, but device and system complexity increases
Solution Approach 1:
The UE capability repository serves multiple functions: it stores the mapping between identifiers and capability information, provides retrieval services to the network, and manages the synchronization of capability data. This multi-functional component reduces overall system complexity by centralizing the management of UE capability information rather than requiring each network element to maintain separate copies.
3Quantity of substance
If identifiers are used instead of full capability information, then network traffic is reduced, but information retrieval complexity increases
Solution Approach 1:
The UE capability information and its corresponding identifiers are pre-stored in the UE capability repository before any retrieval operation. This preliminary action allows the network to quickly retrieve capability information by simply providing an identifier, eliminating the need for complex real-time processing or reconstruction of capability data during operation.

AI summary
A carrier network may provide UE capability message handling with reduced network traffic using a UE capability repository. For example, a Mobility Management Entity (MME) may receive, from a user equipment (UE), a token associated with UE capability information of the UE, transmit, to a UE capability repository, a request for UE capability information of the UE based at least in part on the token, receive, from the UE capability repository, the UE capability information of the UE associated with the token, and perform operations with the UE based on the UE capability information of the UE associated with the token.
