METHOD FOR SECURING PRIVACY IN THE AUTOMATIC ANSWER MODE OF PUSH-TO SERVICE

摘要

A method for securing privacy in the automatic answer mode of a PT service is provided to include privacy information in an automatic answer message transmitted from an invited-side PT server to an inviting-side PT server and enable the inviting-side PT server to generate an alarm message including the connection information and ID(Identification) information of a respondent in response to the received privacy information and transmit the alarm message to an inviting PT client, thereby preventing the ID of an invited PT client from being opened regardless of the intention of the invited PT client. A method for securing privacy in the automatic answer mode of a PT(Push-To) service comprises the following steps of: allowing an invited-side PT server(36) to receive an SIP(Session Initiation Protocol) invite message from an inviting-side PT server(26)(S202); and allowing the invited-side PT server to transmit an automatic response message including privacy information about the invited-side PT server to the inviting-side PT server in response to the SIP invite message(S211).
