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.
