    • Disclosed is a method for enabling a terminating-side Push-To-Talk (PTT) over Cellular (PoC) client to open a PoC session by using a pre-established session, and to maintain the pre-established session when the terminating-side PoC client terminates the open PoC session, and a PoC system and a PoC User Equipment (UE) for implementing the same. To this end, a REFER BYE message is used to terminate the PoC session while keeping the pre-established session maintained. The REFER BYE message must include information, such as pre-established session parameter information, a session IDentifier (ID), etc. Also, the REFER BYE message is transmitted from the PoC client to the PoC server, and the PoC server receives the REFER BYE message, checks the contents of a header in the received message, and terminates the PoC session while keeping the pre-established session maintained when a specified condition is satisfied.
    • 公开了一种使终端侧按通话(PTT)通过蜂窝(PoC)客户机通过使用预先建立的会话来打开PoC会话的方法,并且当终端侧保持预先建立的会话时 PoC客户端终止开放的PoC会话,PoC系统和PoC用户设备(UE)实现该PoC会话。 为此,使用REFER BYE消息来终止PoC会话,同时保持预先建立的会话。 REFER BYE消息必须包括诸如预先建立的会话参数信息,会话标识符(ID)等的信息。此外,REFER BYE消息从PoC客户端发送到PoC服务器,PoC服务器接收REFER BYE消息,在接收到的消息中检查报头的内容,并在满足指定条件的同时保持预先建立的会话,终止PoC会话。
