Caller Information Provision via Dual Network Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice call communication systems, particularly in 2G and 3G networks, face challenges in providing real-time caller information to the called party due to the limitations of Internet Protocol Multimedia Subsystems (IMS) and packet switched networks, which result in delayed information delivery and user dissatisfaction.
Innovation Solution
A method and device that utilize a combination of packet switched and circuit switched networks to send voice call-related information from the calling party to the called party in real time, allowing the called party to receive this information before responding to the call setup message, thereby improving user satisfaction and reducing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If packet switched networks are used for voice call information delivery, then network flexibility and future-proofing are improved, but information delivery delay increases and user satisfaction deteriorates
Solution Approach 1:
The patent segments the communication system into two independent networks: a packet switched network for flexible information delivery and a circuit switched network for real-time voice communication. This segmentation allows each network to be optimized for its specific function, resolving the contradiction between flexibility and delay.
Solution Approach 2:
The patent introduces an intermediary mechanism where the packet switched network delivers caller information to the called party's device before the circuit switched network establishes the voice call. This intermediary approach allows information to be prepared and delivered in advance without interfering with the real-time voice conversation.
2Speed
If IMS is implemented for real-time communication, then information delivery speed is improved, but network maturity and reliability deteriorate
Solution Approach 1:
The patent applies preliminary action by having the packet switched network deliver caller information to the called party before the voice call is actually established. This allows the information to be ready in advance, and when the circuit switched network becomes available, the information can be immediately presented without delay.
3Ease of operation
If caller information is presented during call setup, then user engagement is improved, but call setup complexity increases
Solution Approach 1:
The patent segments the call setup process into two independent phases: information delivery phase via packet switched network and voice connection phase via circuit switched network. This segmentation simplifies the overall complexity by handling information delivery separately from voice connection establishment.

AI summary
By the present invention are disclosed a method for providing and a method for obtaining voice call related information from a first party device (100) to a second party device (200), prior to establishing a voice call between the first party device (100) and the second party device (200). Portable communication devices (100, 200, 500) for providing and obtaining of voice call related information also disclosed. The methods comprises sending/obtaining in real time the voice call related information (steps 304, 402) from the first party device (100) to the second party device (200) over a packet switched network, and sending/obtaining a call setup message (steps 308, 410) over a circuit switched network, of the voice call from the first party device (100), so that the voice call related information can be presented to a user of the second party device (200) before responding to the call setup message.
