By simply pressing a button for to-Talk (PTT), voice can be transmitted to at least one counterpart terminal in 1: 1 or 1: N without any connection procedure.

The user presses a button for a PTT and speaks a word to be transmitted to the other party when voice request is successful. That is, a user who presses the PTT button speaks after obtaining a voice from the PoC server. At this time, the PoC server transmits the voice signal to a terminal of a designated group or all terminals respectively.

In the above-mentioned Push-to-talk On Cellular (PoC) service, a user who obtains a voice in a voice transmits a voice to terminals within a specified group. If there is a receiver that cannot participate in a PoC call, such as when the terminal is placed elsewhere, the receiver has no way of knowing the details of the PoC call between people except themselves.

Accordingly, an object of the present invention is to provide a mobile communication system and a communication method for a PoC service that can overcome the limitations of the prior art as described above and provide a missed PoC call history.

The PoC server 120 does not receive a call from the first mobile communication terminal 110 among the mobile communication terminals 140-1 to 140 -N included in the first group or cannot participate in a PoC call. After storing the contents of the conversation between the mobile communication terminals 140-1 to 140 -N of the first group for one mobile communication terminal 150-1 to 150 -N, the stored voice data is converted into a PoC call. Store in the voicemail box of the mobile communication terminal (150-1 ~ 150-N) that did not participate in. Alternatively, the contents of the call proceeding between the mobile communication terminals 140-1 to 140 -N of the first group are immediately transmitted, that is, the mobile communication terminals 150-1 to 150 -N that do not participate in the PoC call in real time. You can also save it to your voicemail.

Accordingly, the PoC server 120 informs the mobile communication terminals 150-1 to 150-N that have not participated in the PoC call through the communication network 130 to notify that the PoC call is stored in the voicemail box (Short Message Service). : SMS) Send a message. To this end, the PoC server 120 may be configured to include a Short Message Service Center (SMSC) for transmitting a short message indicating the storage of the PoC call contents. The SMSC may be a PoC-only SMSC for transmitting only a short message indicating the storage of the PoC conversation.

The user of the mobile communication terminal receiving the short message may check the received message and connect to a voice mailbox to listen to the stored conversation.

Although not shown, the communication network 130 may include a base station, a base station controller, a mobile switching center, and the like for a mobile communication service including a PoC service in addition to the PoC server 120.
