Data acquisition method and apparatus for wireless communication system

摘要

A method and a terminal for acquiring information on the media supported by an emergency center to provide the terminal with the emergency call service using non-voice media as well voice media are provided. A method includes receiving information on media supported by an Internet Protocol (IP) Multimedia Subsystem (IMS) from a server, storing the information on the media supported by the IMS, and transmitting a signal to a Public Safety Answering Point (PSAP) based on the information on the media supported by the IMS and the terminal. The emergency call processing method of the present invention allows only the terminal capable of NOVES to perform the media information acquisition procedure, thereby avoiding overhead caused by media acquisition attempts of a large number of terminal.

1. A method for transmitting an emergency call by a terminal, the method comprising:
receiving, from a server, a first message including information on a media type supported by an internet protocol multimedia subsystem (IMS); identifying whether a non-voice media type is supported by the IMS based on the first message; transmitting, to a public safety answering point (PSAP), if the non-voice media type is supported by the IMS based on a result of the identification, a second message including information on a media type supported by the terminal, the second message identified based on the first message; and transmitting, to the PSAP, if the non-voice media type is not supported by the IMS based on the result of the identification, an invite message to establish a voice emergency call.
