Abstract

Technology for initiating emergency calls is disclosed. A minimum set of emergency related data (MSD) associated with the emergency call may be identified at a terminal equipment (TE) of a mobile terminal. An attention (AT) command may be generated that includes the MSD and selected configuration information related to the emergency call. The AT command may be sent from the TE of the mobile terminal to a mobile termination (MT) of the mobile terminal in order to setup the emergency call, wherein the mobile terminal (MT) routes the emergency call to a public safety answering point (PSAP) in a communication network.
