Abstract

Embodiments include a system, method, and computer program product for improving public safety communications and real-time information sharing to enable a public safety user to access available, secure private wireless communications (PWC) networks within a vicinity of an emergency for communications and data-sharing purposes. In an embodiment, a universal encryption key (UEK) is stored on a public safety access device. The public safety access device is providing access to a secure PWC network. The UEK is a key established by a certificate authority that enables public safety personnel to access the secure PWC network. Then, a public safety encryption key (PSKey) is received by the public safety access device from a user communication device. The public safety access device enables access for the user communication to access the secure PWC network upon a determination that the received PSKey is associated with the UEK.

Claims

1. A system, comprising:

a memory;

an encrypted key repository coupled to the memory and configured to store a public safety encryption key (PSKey) and a universal encryption key (UEK) associated with the PSKey that enables public safety personnel to access a secure private wireless communications (PWC) network, wherein the UEK is a key established by a certificate authority separate from the system;

a processor configured to execute an alert module and coupled to the encrypted key repository to;

receive an emergency notification from an emergency caller;

obtain location information indicating a location of the emergency caller, wherein the location information is obtained by an originating emergency call telephone number or the location of a calling device associated with the emergency caller;

determine within a proximity of the location of the emergency caller one or more wireless communication devices that use the UEK associated with the PSKey, wherein the one or more wireless communication devices provide the public safety personnel with access to the secure PWC network;

transmit the PSKey to the one or more wireless communication devices;

enable the one or more wireless communication devices to permit a user device, operated by the public safety personnel, to access the secure PWC network; and

wherein the alert module is further configured to establish communication channels within the secure PWC network between the user devices and a video management system, wherein the video management system allows the user devices to access at least one of audio and video views from the emergency location.

2. The system of claim 1, wherein the alert module is further configured to

monitor for the emergency notification received by an emergency dispatch system or other public safety communication or notification system.

3. The system of claim 1, wherein the transmission of the PSKey initiates the receipt of emergency information from the one or more wireless communication devices.

4. The system of claim 1, wherein the alert module is further configured to:

identify predetermined user devices and associated user devices in relation to the determined one or more wireless communication devices.

5. The system of claim 1, wherein the alert module is further configured to:

generate an alert message; and

transmit the alert message to the predetermined user devices and associated user devices.

6. The system of claim 5, wherein the alert message includes a notification of an emergency event.

7. The system of claim 6, wherein the alert message includes information useful to first responders in emergencies.

8. The system of claim 1, wherein the transmission of the PSKey initiates commands and functions of the one or more wireless communication devices to authenticate the public safety personnel operating the user device to enable access of the user device to the secure PWC network.

9. The system of claim 8, wherein the commands and functions include alarms, public announcement, and mass notification.

10. The system of claim 1, wherein the secure PWC network comprises a secure Wi-Fi network.

11. A method, comprising:

storing a public safety encryption key (PSKey) and a universal encryption key (UEK) on an encrypted key repository, wherein the PSKey is associated with the UEK to enable public safety personnel to access a secure private wireless communications (PWC) network, wherein the UEK is a key established by a certificate authority separate from the repository;

receiving, by an alert module to be executed by a processor and coupled to the encrypted key repository, an emergency notification from an emergency caller, wherein the location information is obtained by an originating emergency call telephone number or the location of a calling device associated with the emergency caller;

obtaining, by the alert module, location information indicating a location of the emergency caller;

determining, by the alert module, within a proximity of the location of the emergency caller one or more wireless communication devices that use the UEK associated with the PSKey, wherein the one or more wireless communication devices provide the public safety personnel with access to the secure PWC network;

transmitting, by the alert module, the PSKey to the one or more wireless communication devices;

enabling, by the alert module, the one or more wireless communication devices to permit a user device, operated by the public safety personnel, to access the secure PWC network; and

establishing communication channels within the secure PWC network between the user devices and a video management system, wherein the video management system allows the user devices to access at least one of audio and video views from the emergency location.

12. The method of claim 11, further comprising:

monitoring for the emergency notification received by an emergency dispatch system or other public safety communication or notification system.

13. The method of claim 11, wherein the transmission of the PSKey initiates the receipt of emergency information from the one or more wireless communication devices.

14. The method of claim 11, further comprising:

identifying predetermined user devices and associated user devices in relation to the determined one or more wireless communication devices.

15. The method of claim 11, further comprising:

generating an alert message; and

transmitting the alert message to the predetermined user devices and associated user devices.

16. The method of claim 15, wherein the alert message includes a notification of an emergency event.

17. The method of claim 15, wherein the alert message includes emergency information useful to first responders in emergencies.

18. The method of claim 11, wherein the transmission of the PSKey initiates commands and functions of the one or more wireless communication devices to authenticate the public safety personnel operating the user device to enable access of the user device to the secure PWC network.

19. The method of claim 18, wherein the commands and functions include alarms, public announcement, and mass notification.

20. The method of claim 11, wherein the secure PWC network comprises a secure Wi-Fi network.
