Abstract
A network component is provided. The network component including a component configured such that the network transmits a response message containing an indicator indicating that a first message is an emergency-related request, and such that the network receives a second message containing information associated with a user equipment (UE).
Claims20
A method for a user equipment (UE) to respond to an emergency-related message comprising:
- sending, from the UE, a first Session Initiation Protocol (SIP) request message;
- receiving, at the UE, a SIP rejection response message comprising a P-Asserted Identity header field, wherein the P-Asserted Identity header field comprises an indicator indicating that the first SIP request message is an emergency-related request, and a contact header field of the SIP rejection response message comprises a Uniform Resource Name (URN) of an emergency service;
- and
- in response to receiving the SIP rejection response message, sending, from the UE, a second SIP request message towards a Public Safety Answering Point (PSAP), wherein the second SIP request message includes the URN of the emergency service and emergency-related information associated with the UE.
A user equipment (UE), comprising:
- at least one hardware processor;
- and
- a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the UE to perform operations comprising:
- sending, from the UE, a first Session Initiation Protocol (SIP) request message;
- receiving, at the UE, a SIP rejection response message comprising a P-Asserted Identity header field, wherein the P-Asserted Identity header field comprises an indicator indicating that the first SIP request message is an emergency-related request, and a contact header field of the SIP rejection response message comprises a Uniform Resource Name (URN) of an emergency service;
- and
- in response to receiving the SIP rejection response message, sending, from the UE, a second SIP request message towards a Public Safety Answering Point (PSAP), wherein the second SIP request message includes the URN of the emergency service and emergency-related information associated with the UE.
A non-transitory computer-readable medium storing instructions which, when executed, cause a computing device to perform operations comprising:
- sending, from a user equipment (UE), a first Session Initiation Protocol (SIP) request message;
- receiving, at the UE, a SIP rejection response message comprising a P-Asserted Identity header field, wherein the P-Asserted Identity header field comprises an indicator indicating that the first SIP request message is an emergency-related request, and a contact header field of the SIP rejection response message comprises a Uniform Resource Name (URN) of an emergency service;
- and
- in response to receiving the SIP rejection response message, sending, from the UE, a second SIP request message towards a Public Safety Answering Point (PSAP), wherein the second SIP request message includes the URN of the emergency service and emergency-related information associated with the UE.
