摘要： A method and system for controlling a talk time for a PoC user is provided, capable of freely extending and using the talk time according to whether there is a floor requester or a priority when a talker obtains a floor during PoC communication. The method includes determining whether a talk limit time of a PoC client that is transferring a talk burst is close at hand; when the talk time limit is close at hand, determining whether or not a floor requester who makes a request for a floor is in a floor list for storing the floor requester; and when the floor requester is not in the floor list, extending the talk time and transferring the talk burst.

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 and system for dividing a signal push-to-talk-over-cellular (PoC) group session are provided. The method includes requesting, at a PoC client, session division to a participating PoC function (PF) of a PoC server that manages a PoC session to which the PoC client belongs; requesting, at the PF of the PoC server, the session division to a controlling PoC function (CF) of a PoC server; transmitting, at the CF of the PoC server, information necessary for a new PoC session to at least one PoC client that desires to participate in the new PoC session while requesting the session division; and connecting, at the PoC client which is to participate in the new PoC session, to a CF of a PoC server which manages the new PoC session through a CF of an existing PoC server to thereby participate in the new PoC session.

摘要： A method is provided to establish an ad-hoc PoC group session by causing a PoC client with a pre-established session to use an existing session as a conference server for a group PoC call and by including many individuals and members of at least one PoC group among talk targets. In the method, a session invitation proxy message, which includes session dialog information, entry uniform resource identifiers (URIs), and a Session Initiation Protocol (SIP) message method, is transmitted to an originating PoC server in a state in which the pre-established session is established. The originating PoC server transmits the message based on the SIP message method to a destination address included in the session invitation proxy message. Finally, the ad-hoc session is established between an originating PoC system and the destination address included in the session invitation proxy message.

摘要： Provided is a method and system for granting the floor in a PoC network, in which, when a PoC server makes a request to establish a PoC session according to preset information of a PoC client wishing to make a PoC call rather than a session invitation request of the PoC client, an INVITE message is sent to the PoC client, including content related to grant of the session's initial talk turn, thereby lessening the signaling burden of a talk burst control protocol message. The method includes sending an INVITE message to a terminating PoC client when it is determined that session initiation requirements are met, and sending the INVITE message to an originating PoC client when a response signal to the INVITE message is received from the terminating PoC client.

摘要： A push to talk (PTT) system. Where when there is a call connection request to any terminal in a PTT system with a pre-established session, a query message is transmitted to a PTT terminal receiving the call connection request in order to determine to accept a call request, and a determination is made as to whether to connect the call based on a response message, this preventing a waste of resources and time due to unnecessary session establishment.

摘要： A system and a method for establishing a group messaging session in consideration of a group policy in a communication system. A transmitter-side terminal stores information on a group policy in a group information storage unit, and transmits, to a server, an INVITE message requiring application of the group policy to generation of a group messaging session. The server receives the INVITE message, recognizes that the group policy should be applied to the generation of the group messaging session, and acquires the information on the group policy from the group information storage unit. The server transmits the INVITE message including the acquired group policy information to a receiver-side terminal that is invited to participate in the group session, and receives a response from the receiver-side terminal.
