Abstract

A generic portable PSAP comprises a field satellite link, a network element, an Internet Protocol (IP) based PSAP switch, and customer premises equipment. The generic portable PSAP is an end-to-end portable emergency call center that local and VoIP carriers can use to connect to a new “temporary” PSAP in emergency situations where a given PSAP is unable to function in its normal facility. The portable emergency call center routes and receives emergency services events from landline, voice over Internet Protocol (VoIP), and/or wireless carriers without need for customization from a given network architecture. The generic portable PSAP enables local management of emergency event acquisition and dispatch in the case of a major disaster, or some other reason for use of a mobile PSAP.

Claims

1. A portable Public Safety Access Point (PSAP), comprising:

an Internet Protocol (IP) input;

a field satellite link to receive an emergency call via said Internet Protocol (IP) input;

an IP based PSAP switch to receive said emergency call received by said field satellite link; and

customer premises equipment (CPE) allowing an emergency call center operator to handle said emergency call routed by said IP based PSAP switch to said CPE.

2. The portable Public Safety Access Point (PSAP) according to claim 1, wherein:

said IP input includes a TCP/IP interface.

3. The portable Public Safety Access Point (PSAP) according to claim 1, further comprising:

a network element interposed between said field satellite link and said IP based PSAP switch.

4. The portable Public Safety Access Point (PSAP) according to claim 3, wherein:

said network element is a router.

5. The portable Public Safety Access Point (PSAP) according to claim 4, wherein:

said router is a voice over Internet Protocol (VoIP) based router.

6. A method of providing a temporary Public Safety Access Point (PSAP) for use with landline, wireless and voice over Internet Protocol (VoIP) emergency callers, comprising:

receiving an emergency call over an Internet Protocol (IP) interface;

a field satellite link receiving said emergency call via said Internet Protocol (IP) interface;

routing said emergency call received by said field satellite link to an IP based PSAP switch; and

presenting said emergency call to an operator at customer premises equipment (CPE) associated with said temporary PSAP.

7. The method of providing a temporary Public Safety Access Point (PSAP) for use with landline, wireless and voice over Internet Protocol (VoIP) emergency callers according to claim 6, wherein:

said IP input includes a TCP/IP interface.

8. The method of providing a temporary Public Safety Access Point (PSAP) for use with landline, wireless and voice over Internet Protocol (VoIP) emergency callers according to claim 6, further comprising:

interposing a network element between said field satellite link and said IP based PSAP switch.

9. The method of providing a temporary Public Safety Access Point (PSAP) for use with landline, wireless and voice over Internet Protocol (VoIP) emergency callers according to claim 8, wherein:

said network element is a router.
