摘要： A method for performing session merging between PoC sessions under the environment of multiple PoC sessions is provided. A merging PoC client sends a request for the session merging with a merged session to a PoC server managing a merging session to which the PoC client belongs. The PoC server managing the merging session sends a session merge request to a PoC server managing the merged session. Negotiation of a CF (Controlling PoC Function) for managing a session to be merged is performed between the PoC server of the merging session and the PoC server of the merged session. When an entire CF of the session to be merged is selected as the negotiation between the PoC servers is completed, the PoC server of the merged session sends an UPDATE message of modified media parameters to a PoC client of the merged session. The PoC server of the merging session sends, to a PoC client of the merging session, a NOTIFY message of a merge request notifying that the PoC server of the merging session is selected as the entire CF.
摘要翻译：提供了一种在多个PoC会话环境下执行PoC会话之间的会话合并的方法。合并PoC客户端将会话合并的请求发送到管理PoC客户端所属的合并会话的PoC服务器的合并会话。管理合并会话的PoC服务器将会话合并请求发送到管理合并会话的PoC服务器。在合并会话的PoC服务器和合并会话的PoC服务器之间执行用于管理要合并的会话的CF（控制PoC功能）的协商。当PoC服务器之间的协商完成时，选择要合并的会话的整个CF，则合并会话的PoC服务器将经过修改的媒体参数的UPDATE消息发送到合并会话的PoC客户端。合并会话的PoC服务器向合并会话的PoC客户端发送通知合并请求的PoC服务器被选为整个CF的合并请求的NOTIFY消息。

摘要： Disclosed is an apparatus for monitoring a multisession including one-to-one calls and group calls at a same time in a wireless communication system performing group communication. The apparatus includes an intermediate unit, a control unit and a text conversion unit. The intermediate unit receives a request message for a monitoring set up from a user terminal, manages sessions correlating with each user, and intermediates a voice message received from each of the correlating sessions. The control unit confirms a session and a set session monitoring method of the voice message received from each of the correlating sessions, and transmits the received voice message according to a result of the confirming. The text conversion unit converts the voice message into a text form, when the voice message is in an inactive session and the session monitoring method is set to use text.

摘要： A method allows an individual PoC client and a PoC client belonging to a specific PoC group to participate in a session as extended targets while a PoC group talk is proceeding. When the PoC client that is participating in the ad-hoc group talk intends to make the ad-hoc PoC group session ongoing by adding both a plurality of individuals and members of at least one PoC group to the existing session as preliminary talkers, the list information is obtained by identifying the group URI at the PoC server. By using SIP or Extended SIP and XCAP in this process, the PoC user that is participating in the group talk transmits the single SIP message through an ongoing session, and invites a specific PoC group and a plurality of PoC users who are designated voluntarily to the ongoing PoC group talk. Thereby, the PoC user can perform the PoC call.
