Temporary Dispatch Talk Group Creation in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public safety agencies face challenges in coordinating inter-agency communications during emergency situations, as conventional wireless networks lack the ability to easily create temporary dispatch talk groups involving members from different agencies, especially when they are supported by separate private wireless networks.
Innovation Solution
A system and method for creating temporary dispatch talk groups in publicly-accessible wireless networks, where a dispatch console operator registers the group in a group database, provides a group ID to members, and manages the communication using existing dispatch talk group IDs, allowing for dynamic formation and expiration of temporary groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dispatch talk groups are created prior to emergency situations using conventional wireless networks, then communication reliability is improved, but adaptability deteriorates because pre-defined groups cannot accommodate dynamic inter-agency coordination needs
Solution Approach 1:
The system transitions from static pre-defined talk groups to dynamic temporary talk groups that can be created on-demand. The talk group creation process is made dynamic by allowing operators to form groups during emergency situations rather than requiring pre-definition, enabling the system to adapt to changing coordination needs while maintaining communication reliability through structured creation procedures
Solution Approach 2:
The system performs preliminary actions by pre-establishing the capability and framework for creating temporary talk groups within the network infrastructure. The network is prepared in advance to support dynamic group creation through database structures and routing mechanisms, even though specific groups are formed later based on actual emergency needs
2Reliability
If separate private wireless networks are used by different public safety agencies, then communication reliability within each agency is improved, but interoperability deteriorates because networks cannot easily interoperate
Solution Approach 1:
The system introduces an intermediary mechanism in the form of a unified group database and standardized creation procedures that enable different private wireless networks to interoperate. The database acts as a mediator that stores and manages temporary talk group information across network boundaries, allowing agencies with separate networks to coordinate communications through a common interface while maintaining their individual network reliability
3Ease of operation
If dispatch talk group membership is defined in advance in wireless network databases, then ease of operation is improved, but device complexity increases due to the need for centralized database management and pre-configuration
Solution Approach 1:
The system extracts the complex database management and pre-configuration requirements from the operational process. By separating the creation phase from the usage phase, the system allows simple on-demand group formation during emergencies while concentrating the complexity in the background infrastructure (database and routing mechanisms) that handles the heavy lifting of membership management and inter-network coordination
Data Source
AI summary
Systems and methods for creating temporary dispatch talk groups are provided. A console receives a request to create a temporary dispatch talk group. The temporary dispatch talk group includes at least two existing talk groups. The console accesses a group database in a publicly-accessible wireless network. The temporary dispatch talk group is created in the group database, along with an identification of the lifetime of the temporary dispatch talk group. A temporary dispatch talk group identifier is provided to at least one member of the temporary dispatch talk group. A talk group call for the temporary dispatch talk group can then be initiated using the temporary dispatch talk group identifier.
