摘要： Provided is a method and system for transmitting media to a receiving PoC user without filtering according to importance indication information of a PoC user trying to transmit the media in a PoC system. Thus, if media transmitted by the PoC user is important, in order to inform the receiving PoC user of this, the PoC user transmits an MBCP Request message containing importance indication information to a PoC server, and the PoC server, which has received the MBCP Request message, transmits an MBCP Taken message containing importance indication information to the receiving PoC user. In addition, if media corresponding to an important message is filtered since media of a primary or locking-in session among a plurality of sessions or other media is being transmitted, the PoC server temporarily stores the media in a local memory or a PoC box and transmits the stored media after the preceding media is completely transmitted.

摘要： A digital DC-DC converter is implemented using first-order delta-sigma modulation, rather than A/D conversion. In the DC-DC converter, a PWM generator converts an input DC voltage to a preset level DC voltage according to an input PWM signal. A converter converts the DC voltage from the PWM generator to a preset level voltage. A delta-sigma modulator converts a feedback voltage Vfd corresponding to the output voltage Vout of the converter to a 1-bit digital voltage Vo according to a preset reference voltage Vref. A counter counts logic 1's in 1-bit digital voltage signals Vo from the delta-sigma modulator. A delay controller controls a high-level delay time according to the number of logic 1's counted by the counter and transfers a PWM signal having the controlled high-level delay time to the PWM generator.

摘要： A method, user equipment, and system are provided which can open an ad-hoc Push-To-Talk (PTT) over Cellular (PoC) session for a call target group whose group identifier is managed in a remote network domain when the ad-hoc PoC session is opened. A PoC client requesting session initiation sends, to a first PoC server of a home network, a session INVITE message containing information of at least one group identifier. The first PoC server checks the group identifier information and sends a group list information request message to a second PoC server hosting a group identifier when identifier information of a network group other than the home network is included. The second PoC server acquires list information about a group in the request message and sends the information to the first PoC server.

摘要： Disclosed is a method and a system for a Push-To-Talk (PTT) over Cellular (PoC) session open between PoC clients supporting various types of media. Although a PoC client providing an Open Mobile Alliance (OMA) PoC multimedia communication service supports a plurality of uncommon types of media, it is possible to open a session according to media types in an independent and easier manner. Also, when a new media type is supported by a new participant during a session, it is possible to add the new media type when granting the next floor. In addition, it is possible to selectively transmit media according to media types based on the PoC user's choice.
