Abstract
In some implementations, a call session control function (CSCF) may receive, from a user equipment (UE), a message associated with a text message sent from the UE to an emergency number. The CSCF may add, based on the message being associated with the text message sent to the emergency number, an enhanced 911 (e911) attribute to the message, wherein the e911 attribute provides prioritized handling for the message during network congestion in relation to messages without the e911 attribute. The CSCF may transmit the message having the e911 attribute.
Claims20
A method, comprising:
- receiving, by a call session control function (CSCF) and from a user equipment (UE), a message associated with a text message sent from the UE to an emergency number;
- adding, by the CSCF and based on the message being associated with the text message sent to the emergency number, an enhanced 911 (e911) attribute to the message, wherein the e911 attribute provides prioritized handling for the message during network congestion in relation to messages without the e911 attribute;
- transmitting, by the CSCF to a secure telephone identity authentication service (STI-AS), a request to attest a caller identity and the e911 attribute;
- receiving, by the CSCF and from the STI-AS, a response that includes an identity associated with an attestation of the caller identity and the e911 attribute;
- inserting, by the CSCF, the identity associated with the attestation of the caller identity and the e911 attribute into the message;
- and
- transmitting, by the CSCF, the message having the e911 attribute.
A network element, comprising:
- one or more processors configured to:
- receive, from a user equipment (UE), a message associated with a text message sent from the UE to an emergency number;
- add, based on the message being associated with the text message sent to the emergency number, an enhanced 911 (e911) attribute to the message, wherein the e911 attribute provides prioritized handling for the message during network congestion in relation to messages without the e911 attribute;
- transmit, to a secure telephone identity authentication service (STI-AS), a request to attest a caller identity and the e911 attribute;
- receive, from the STI-AS, a response that includes an identity associated with an attestation of the caller identity and the e911 attribute;
- insert the identity associated with the attestation of the caller identity and the e911 attribute into the message;
- and
- transmit the message having the e911 attribute.
A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a network element, cause the network element to:
- receive, from a user equipment (UE), a message associated with a text message sent from the UE to an emergency number;
- add, based on the message being associated with the text message sent to the emergency number, an enhanced 911 (e911) attribute to the message, wherein the e911 attribute provides prioritized handling for the message during network congestion in relation to messages without the e911 attribute;
- transmit, to a secure telephone identity authentication service (STI-AS), a request to attest a caller identity and the e911 attribute;
- receive, from the STI-AS, a response that includes an identity associated with an attestation of the caller identity and the e911 attribute;
- insert the identity associated with the attestation of the caller identity and the e911 attribute into the message;
- and
- transmit the message having the e911 attribute.
