Capability ID–Linked Radio Profile Caching for Lower Control Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent exchange of large radio capability containers over the air interface leads to inefficiencies in air interface capacity and latency in control plane procedures, particularly due to the use of multiple UE Capability IDs (UECAPIDs) assigned by networks, which results in redundant network processing for radio reconfigurations.
Innovation Solution
Implementing a system to cache configuration profiles associated with capability IDs, allowing devices to transmit and receive sets of radio configuration profiles based on capability indications, thereby reducing the need for repeated network processing and optimizing radio reconfiguration procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple UE Capability IDs are assigned by the network to control radio capability size, then the network can manage UE capabilities more flexibly, but redundant network processing for radio reconfigurations occurs leading to increased latency and reduced air interface capacity
Solution Approach 1:
The network pre-processes and determines radio configuration profiles associated with each capability ID in advance, storing them in a cache. When a UE provides a capability ID, the network can immediately retrieve the corresponding pre-determined configuration profile without performing redundant processing, thus reducing latency while maintaining control flexibility
Solution Approach 2:
Instead of transmitting full radio capability containers repeatedly, the system uses compact capability IDs as references. The network maintains cached copies of configuration profiles associated with each capability ID, allowing efficient retrieval and transmission of only the necessary configuration data rather than redundant full capability information
2Loss of information
If large radio capability containers are frequently exchanged over the air interface, then complete capability information can be provided, but air interface capacity is reduced and processing efficiency deteriorates
Solution Approach 1:
The patent extracts only the essential capability identification (capability ID) from the full radio capability container and transmits this compact identifier over the air interface. The network uses this ID to retrieve the complete configuration profile from its cache, thus providing complete capability information while minimizing air interface transmission requirements and improving capacity
Solution Approach 2:
The system segments the radio capability information into two parts: a compact capability ID transmitted over the air interface, and the full configuration profile stored and managed by the network. This segmentation allows efficient wireless transmission of identification while maintaining access to complete capability information through network-side storage and retrieval

AI summary
Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of caching the configuration profiles associated with a capability ID. The method comprising receiving, at the first device and from a second device, a capability indication of the second device, the capability indication associated with at least one capability of the second device for performing radio access to the first device; determining a set of radio configuration profiles for the second device at least based on the capability indication, the set of radio configuration profiles indicating a plurality of available configuration parameters of the radio access; and transmitting the set of radio configuration profiles to the second device, to cause the second device to establish a connection with the first device. In this way, the additional network processing for generating a new radio configuration may be potentially saved and therefore the network efficiency for transmitting the radio configurations to the terminal device can be improved.
