PoC Server Emergency Call Group Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Push-to-Talk over Cellular (PoC) services lack a defined dispatcher function and do not provide a solution for emergency calls, limiting their functionality and effectiveness in emergency communication scenarios.
Innovation Solution
A method and system for processing emergency calls in a PoC service, where a PoC server receives a request from a dispatcher to establish an emergency call group, adds the dispatcher as a first party, and forwards a two-way session between the dispatcher and a mobile terminal upon an emergency call request, enabling efficient emergency communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a PoC server establishes an emergency call group with a dispatcher as a first party and forwards a two-way session between the dispatcher and mobile terminal, then emergency communication functionality is enabled, but the system complexity increases due to the need for dispatcher function definition and emergency call processing logic
Solution Approach 1:
The PoC server is extended to perform multiple functions: it acts as both a standard PoC service provider and an emergency call processing system. The server establishes emergency call groups, manages dispatcher functions, and handles two-way session forwarding, thereby enabling universal emergency communication capabilities across the existing PoC infrastructure without requiring separate dedicated emergency communication systems
Solution Approach 2:
The dispatcher serves as an intermediary entity between mobile terminals and the PoC server in emergency scenarios. The dispatcher receives emergency call requests, manages the emergency call group, and coordinates the two-way session establishment, thereby mediating the complex interactions and simplifying the overall system architecture by centralizing emergency call control functions
2Reliability
If the PoC service implements dispatcher function and emergency call processing, then emergency response capability is improved, but the loss of time during emergency call setup may increase due to additional processing steps
Solution Approach 1:
The PoC server pre-establishes emergency call groups and pre-configures dispatcher functions before actual emergency incidents occur. By preparing the emergency communication infrastructure in advance, the system can rapidly respond to emergencies without experiencing delays from last-minute setup, thereby reducing call setup time while maintaining reliable emergency response capability
Solution Approach 2:
The system implements feedback mechanisms where the PoC server continuously monitors the status of emergency call groups and dispatcher availability. This real-time feedback enables the server to quickly identify and activate appropriate emergency resources, optimizing the emergency call setup process and minimizing delays while ensuring reliable emergency response

AI summary
The present invention provides a method, a server and a system for processing an emergency call in a PoC service. The method includes: receiving, by a PoC server, an emergency call request sent by an initiator; adding, by the PoC server, a mobile terminal as one party to an established emergency call group according to the emergency call request, where a first party of the emergency call group is a dispatcher; and forwarding, by the PoC server, a two-way session between the mobile terminal and the dispatcher. In the embodiments of the present invention, an emergency call may be provided in a PoC service.
