摘要： an Disclosed are a method and an apparatus for providing a PoC service in a radio communication system supporting a BCAST service. For the PoC service in the radio communication system supporting the BCAST service, a first terminal joining the PoC service through the BCAST service transmits user data for the PoC service over an uplink dedicated bearer, and the user data reach a PoC server, which controls the PoC service, over the uplink dedicated bearer. The PoC server transmits the user data to a BCAST server controlling the BCAST service and, from the BCAST service server, the user data reach plural second terminals joining the PoC service over a downlink shared bearer. In this way, radio resources can be efficiently used when the PoC service is performed in a random area, and an a BCAST service operator d a PoC service operator is provided.

摘要： As described above, when a particular PoC client participating in a PoC session requests media transmission to a PoC server during transmission of media from another PoC client, the PoC server transitions the PoC client with the floor to a suspended state by sending an MB Suspend message and grants the floor to the requesting PoC client. After media transmission of the interrupting PoC client, the PoC server returns the floor to the interrupted PoC client. Therefore, the privileged PoC client in a current PoC infrastructure interrupts the ongoing conversation and sends media, after which the floor is returned to the interrupted PoC client without issuing an explicit media request from the interrupted PoC client. Even in the pre-emptive case scenario where the pre-emptive PoC client interrupts the ongoing conversation, the conversation can be continued in a natural way.
摘要翻译：如上所述，当参与PoC会话的特定PoC客户端在从另一个PoC客户端传输媒体期间向PoC服务器请求媒体传输时，PoC服务器通过发送MB暂停消息将具有地板的PoC客户端转换到暂停状态并请求请求的PoC客户端。在中断PoC客户端的媒体传输后，PoC服务器返回到中断的PoC客户端。因此，当前PoC基础设施中的特权PoC客户端会中断正在进行的会话并发送媒体，之后将其发送到中断的PoC客户端，而不会从中断的PoC客户端发出显式媒体请求。即使在抢先的PoC客户端中断正在进行的对话的抢先情况下，也可以以自然的方式继续对话。

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.
