IMS Conference Service for Anonymous User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conference service provided through an Internet Protocol (IP) multimedia subsystem (IMS) in 4G or 5G communication networks has limited functionality for anonymous user equipment (UE), restricting the provision of various functions for multiple UEs participating in a conference call.
Innovation Solution
An electronic device with a communication module and processor identifies conference events, determines if participating devices are anonymous, generates a shared identification key, and transmits it to anonymous devices, enabling the establishment of conference calls and call separation operations among multiple external electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conference service is provided through IMS in 4G or 5G networks, then multi-party calling functionality is achieved, but functionality for anonymous user equipment is limited
Solution Approach 1:
The patent segments the conference service into two distinct modes: anonymous conference mode and non-anonymous conference mode. This segmentation allows the system to provide enhanced functionality specifically for anonymous UEs without complicating the overall IMS structure, as each mode can be handled with appropriate identification keys and session management procedures
Solution Approach 2:
The patent introduces an identification key as an intermediary element that enables anonymous UEs to participate in conference services. This key acts as a mediator between the anonymous UE and the conference service, allowing the UE to establish conference calls and perform call separation operations without revealing its identity, thus enhancing functionality while maintaining system structure
2Ease of operation
If anonymous UEs participate in conference calls, then user privacy is protected, but call management functions are restricted
Solution Approach 1:
The patent applies local quality by providing different levels of functionality based on the conference mode. In anonymous conference mode, call separation function is enabled locally for anonymous UEs through the use of identification keys, while maintaining privacy by not requiring UE identification information. This allows call management functions to be available where needed without compromising overall anonymity
3Reliability
If identification keys are generated and transmitted to anonymous devices, then secure anonymous communication is enabled, but communication protocol complexity increases
Solution Approach 1:
The patent implements preliminary action by generating and distributing identification keys before anonymous UEs participate in conference services. This advance preparation ensures that when anonymous UEs need to join conferences or perform call separation, the key management infrastructure is already in place, enabling secure communication without adding complexity to the real-time operation
Solution Approach 2:
The identification key serves multiple functions: it enables anonymous UEs to join conference calls, perform call separation operations, and maintain privacy throughout the communication process. This multi-functionality reduces the need for separate mechanisms for each operation, thereby enabling secure anonymous communication while limiting the increase in protocol complexity

AI summary
An electronic device is provided. The electronic device includes a communication circuit, a memory, and a processor configured to identify an occurrence of a conference event for establishing a conference call in which a plurality of external electronic devices participate, identify whether at least one of the plurality of external electronic devices is anonymous, generate an identification key to be mutually shared by a pair of an anonymous electronic device among the plurality of external electronic devices and the electronic device and transmit the identification key to the anonymous electronic device through the communication circuit when the at least one of the plurality of external electronic devices is anonymous, and generate the conference call in which the plurality of external electronic devices participate.
