摘要

Embodiments include a system, method, and computer program product that enable intelligent formation and management of dynamic talk groups. Embodiments include a discretionary sharing mechanism based on invitation and acceptance that allows for dynamic publication or sharing of information in real time among agencies responding to an incident, where the agencies may establish secure communications. Additional embodiments include establishing and associating geographic boundaries of incident sites with talk groups, monitoring conditions that trigger warning messages sent to talk group members, and subscriptions to information channels that allow multimedia information to flow into talk groups.

主权项

1. A method for management of dynamic Push To Talk (PTT) geotalk groups among members of two or more agencies associated with an incident, wherein the two or more agencies communicate securely, wherein an agency includes a collection of communication resources having an administrator, comprising:
creating an incident control area associated with a geographic demarcation of the incident area; electronically transmitting information about the incident control area to the two or more agencies; establishing a talk group permission rule associated with the incident control area for creating an invitation to join a PTT geotalk group; electronically transmitting a joint invitation to the two or more agencies for access to PTT mobile unit users that meet a criteria, wherein the joint invitation includes a request for location information; electronically receiving an acceptance to the joint invitation that includes a User Identity and Credentials of a first PTT mobile unit user, wherein a dynamic access permission managed by a first agency determines what information associated with the User Identity and Credentials of the first PTT mobile unit user are available, and wherein the dynamic access permission changes in real time; based on the dynamic access permission, obtaining a location of the first PTT mobile unit user in real time; when the first PTT mobile unit user is in proximity to the incident control area or is present in the incident control area, determining whether the first PTT mobile unit user is authorized to enter the incident control area based on the dynamic access permission; and when the first PTT mobile unit user is authorized to enter the incident control area and the talk group permission rule is satisfied, electronically transmitting the invitation to join the PTT geotalk group to the first PTT mobile unit user.
