    摘要： Disclosed is a method and a system for providing a terminal-based ringback tone substitute service, as well as a mobile communication terminal for the same. The method includes the steps of (a) receiving a request for an originating call for voice communication with a called terminal from a calling terminal; (b) transmitting a ringback tone start message to the calling terminal, the ringback tone start message being a control message informative of beginning of a ringback tone section; (c) paging the called terminal; (d) transmitting a ringback tone termination message to the calling terminal, the ringback tone termination message being a control message informative of ending of the ringback tone section, and connecting the voice communication between the calling terminal and the called terminal when a response to paging is received from the called terminal; and (e) transmitting the ringback tone termination message to the calling terminal and transmitting unanswered messages to the calling terminal when no response to the paging is received from the called terminal. The mobile communication terminal can play a high-quality ringback tone substitute without being affected by the voice channel environment.

    摘要： Disclosed herein is a fast data call connection method capable of reducing a connection time and increasing the probability of connection success in a CDMA 2000 network.In the fast data call connection method of the present invention, the PDSN transmits a data call connection request message, including an authentication type and a challenge value, to the MS. The MS transmits a data call connection response message, including a response to the challenge value, to the PDSN. The PDSN performs authentication with reference to the data call connection response message, and transmits a data call connection complete message to the MS if authentication succeeds. Accordingly, the present invention is advantageous in that it can reduce connection time, can increase the probability of connection success, and can guarantee compatibility by checking the MS version before a data call connection process is executed.

    摘要： A method and a system for controlling a reverse link rate by using the number of active users who are carrying out communication in a CDMA 1xEV-DO mobile communication system is disclosed. A value of rise-over-thermal (ROT) at each antenna end of a wireless base station is measured and compared with a threshold ROT which defines an allowable limit of the ROT. A reverse activation control bit is set as 0 if the measured ROT value is smaller than or equal to the threshold ROT. The number of the active users is compared with a threshold user number which defines an allowable limit of the active users if the measured ROT value is greater than the threshold ROT. The reverse activation control bit is set as 0 if the number of the active users is smaller than or equal to the threshold user number. The reverse activation control bit is set as 1 if the number of the active users is greater than the threshold user number.
