RCS Origination Forking for Multi-Device Message Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Rich Communication Services (RCS) systems do not effectively manage message origination across multiple devices associated with a single user ID, leading to inconsistencies in displaying outgoing and incoming messages, as messages sent from one device may be received on another, causing confusion in conversation threads.
Innovation Solution
Implementing origination forking in RCS systems, where the RCS server forwards messages to all associated devices with the same user ID, and uses headers to classify messages as incoming or outgoing, ensuring correct display in conversation threads, and devices register their support for origination forking during network registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RCS systems support multiple devices with a single user ID, then device versatility and user convenience are improved, but message origin tracking and conversation thread consistency deteriorate
Solution Approach 1:
The patent introduces an intermediary mechanism (the message forwarding process with origin device identification) that mediates between multiple endpoint devices and the RCS server. The system identifies the original sending device and forwards messages from other devices as if they originated from the identified device, preserving message origin tracking while enabling multi-device support
Solution Approach 2:
The patent implements a copying mechanism where the RCS server forwards messages to additional devices associated with the same user ID. The message content is copied and delivered to multiple devices while maintaining the original message origin information through the identification mechanism
2Stability of the object's composition
If messages are forwarded to all associated devices, then message synchronization across devices is improved, but device complexity and network traffic increase
Solution Approach 1:
The patent implements a universal message handling approach where the RCS server performs multiple functions: identifying the origin device, determining associated devices, forwarding messages appropriately, and managing conversation thread consistency. This multi-functional approach simplifies the overall system architecture while achieving message synchronization across devices
3Adaptability or versatility
If outgoing messages from one device are displayed on another device, then multi-device accessibility is improved, but conversation thread accuracy deteriorates
Solution Approach 1:
The RCS server acts as an intermediary that preserves conversation thread accuracy by identifying the original sending device and forwarding messages with appropriate origin information. This allows messages to be accessible on multiple devices while maintaining accurate conversation threads that reflect the actual message flow

AI summary
In an IMS (IP multimedia system) and/or RCS (rich communication services) environment, devices that support origination forking of various message types are configured to register with an IMS network and to provide an indication that they support origination forking. The IMS network is configured to record this information for its subscribing devices. When the IMS network receives a message request from an origination device, the message request is forwarded to termination devices as well as to other supporting devices that are associated with the user of the origination device.
