Supplementary Service Settings Synchronization Across Protocol Domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no standardized mechanism to synchronize supplementary services settings between network nodes using different protocols (XCAP and 24.010) in wireless communication networks, leading to inconsistent user experiences and increased network complexity.
Innovation Solution
A method where a wireless communication device maintains an authoritative list of supplementary service settings and synchronizes it with the settings stored in network nodes when switching between cells supporting different protocols, ensuring that the latest configuration is applied across all protocol domains without requiring network updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate network nodes store supplementary service settings for different protocols (24.010 and XCAP), then protocol compatibility is maintained, but network complexity increases and settings synchronization becomes difficult
Solution Approach 1:
The patent introduces a synchronization mechanism that acts as an intermediary between the first network node (storing 24.010 settings) and the second network node (storing XCAP settings). When a device switches between protocol domains, the mechanism retrieves settings from the current protocol's network node and synchronizes them with the other protocol domain, ensuring consistency without requiring direct integration between the two separate network nodes.
Solution Approach 2:
The patent performs preliminary synchronization actions by maintaining a mapping between protocol domains and proactively synchronizing settings when devices switch between protocols. This preliminary action ensures that settings are already synchronized before conflicts arise, avoiding the need for complex real-time coordination mechanisms between network nodes.
2Adaptability or versatility
If separate network nodes store supplementary service settings for different protocols, then protocol-specific functionality is preserved, but consistent user experience across protocol domains deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the device monitors which protocol domain it is currently in and automatically triggers synchronization when switching between domains. The device retrieves settings from the active protocol's network node and applies them to the other protocol domain, ensuring that the user experience remains consistent regardless of which protocol domain the device is operating in.
Solution Approach 2:
The patent performs preliminary synchronization by maintaining settings in both protocol domains and proactively updating them when switching occurs. This ensures that settings are already synchronized before the user encounters any inconsistency, maintaining reliable user experience across protocol boundaries.
3Device complexity
If network nodes independently manage supplementary service settings, then network autonomy is maintained, but setting synchronization between protocols becomes inefficient
Solution Approach 1:
The patent enables the wireless communication device to perform self-service synchronization by automatically retrieving settings from the network node corresponding to its current protocol domain and applying them to the other protocol domain. This eliminates the need for the network nodes to actively communicate and synchronize settings with each other, maintaining network autonomy while improving synchronization efficiency.
Solution Approach 2:
Instead of having network nodes actively synchronize settings with each other (traditional approach), the patent inverts the approach by having the device itself perform the synchronization by retrieving settings from the appropriate network node and applying them locally. This reversal maintains network autonomy while significantly improving synchronization efficiency.

AI summary
A method performed by a wireless communication device (UE) adapted to operate in association with a cellular communication network supporting supplementary services is disclosed. The UE is adapted to configure settings of the supplementary services offered by a first type of cell using a first communication protocol, i.e. a layer 3 protocol as specified in 3GPP TS 24.010, in a first list, to configure settings of the supplementary services offered by a second type of cell using a second communication protocol, i.e. a XCAP protocol as specified in 3GPP TS 24.623, in a second list and to keep a third list of settings of the supplementary services used to synchronize the first and second lists when the UE switches from the first type of cell to the second type of cell.
