System, apparatus and method to enable mobile stations to identify calls based on predetermined values set in a call header
First Claim
1. A method for a network to prompt a user equipment to priority handle an emergency call with a Public Safety Access Point (PSAP), comprising:
- establishing, by the PSAP, a communication session with the user equipment;
transmitting a data packet communication originating from the PSAP to the user equipment, wherein the transmitted data packet communication includes a header that identifies the communication session as an emergency call and prompts the user equipment to interrupt a current communication session and thereby priority handle the emergency call; and
setting an “
emergency-callback”
value in the header to identify the communication session as the emergency call.

Abstract
A mobile device/UE identifies calls to or callbacks from a Public Safety Access Point (PSAP) to provide priority handling. When the UE does not detect that the call being made is an emergency call, then the network facilitates identification during call establishment of the emergency nature. The network identifies the call as emergency call in a SIP response by setting the Priority header to a distinctive value (e.g., “emergency-call”) or the “P-Asserted-Identity” to a distinctive value (e.g., “urn:services:sos”). When the PSAP chooses to call back the mobile/UE, the mobile/UE can terminate any ongoing calls and accept this call from the PSAP and can disable other supplementary services (e.g., call waiting, three-way calling, etc.) during the call. A P-Asserted-Identity of the incoming call is set to a distinctive location associated with the PSAP (e.g., “urn:services:sos”). Alternatively, the incoming call has a Priority header set to a distinctive value (e.g., “emergency”, “emergency-callback”).

10. A non-transitory computer readable medium having stored thereon computer executable components for a network to prompt a user equipment to priority handle an emergency call with a Public Safety Access Point (PSAP), the computer executable components comprising:
-
a set of codes for causing a computer to establish a communication session with the user equipment; a set of codes for causing the computer to transmit a data packet communication originating from the PSAP to the user equipment, wherein the transmitted data packet communication includes a header that identifies the communication session as an emergency call and prompts the user equipment to interrupt a current communication session and thereby priority handle the emergency call; and a set of codes for setting an “
emergency-callback”
value in the header to identify the communication session as the emergency call.

11. An apparatus for a network to prompt a user equipment to priority handle an emergency call with a Public Safety Access Point (PSAP), comprising:
-
means for establishing a communication session with the user equipment; means for transmitting a data packet communication originating from the PSAP to the user equipment, wherein the transmitted data packet communication includes a header that identifies the communication session as an emergency call and prompts the user equipment to interrupt a current communication session and thereby priority handle the emergency call; and means for setting an “
emergency-callback”
value in the header to identify the communication session as the emergency call.

12. An apparatus for a network to prompt a user equipment to priority handle an emergency call with a Public Safety Access Point (PSAP), comprising:
-
an uplink and a downlink configured to establish a communication session with the user equipment; a computing platform configured to transmit a data packet communication originating from the PSAP to the user equipment on the downlink, wherein the transmitted data packet communication includes a header that identifies the established communication session as an emergency call and prompts the user equipment to interrupt a current communication session and thereby priority handle the emergency call, wherein the computing platform is further configured to set an “
emergency-callback”
value in the header to identify the communication session as the emergency call. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
