    • 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。

    • A session integration method is provided for integrating a first session between a first entity and a third entity and a second session between a second entity and the third entity in a session-based service environment. The first entity receives a REFER message including dialog information from the second entity, and sends a response message to the received REFER message to the second entity. When header information included in the received REFER message indicates an INVITE message and the dialog information is related to the first entity, the first entity generates a Re-INVITE message and sends the generated Re-INVITE message to an address of a target which is subject to session integration. The address is included in the header information and corresponds to the third entity. The first entity updates the first session into an integrated session with the third entity.
    • 提供了一种会话集成方法,用于在第一实体和第三实体之间集成第一会话,并且在基于会话的服务环境中集成第二实体和第三实体之间的第二会话。 第一实体从第二实体接收包括对话信息的REFER消息,并向第二实体发送响应消息到接收到的REFER消息。 当包含在接收的REFER消息中的报头信息表示INVITE消息并且对话信息与第一实体相关时,第一实体产生Re-INVITE消息,并将生成的Re-INVITE消息发送到作为对象的目标地址 到会话集成。 地址包含在标题信息中,对应于第三个实体。 第一个实体将第一个会话更新为与第三个实体的集成会话。
