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 method and system for guaranteeing a seamless session when replacing a PoC terminal in a PoC system is provided, in which a currently busy PoC client can be replaced in an existing busy PoC session using a PoC compliant client capable of connecting the PoC session, thereby preventing a transmitted media stream of the running PoC session from being lost when the PoC client is replaced. The method includes transmitting, by an arbitrary PoC user, a message for replacing a terminal from a user terminal to a session management server while maintaining the session; receiving, by the session management server, the replacement request message, and transmitting an INVITE message to a terminal to be replaced, or a target terminal; and receiving, by the target terminal, the INVITE message, and media through an existing session. In a situation where there is a need to replace the PoC terminal according to change of the media for the PoC call, request of mobility, etc. by the PoC user, the user is allowed to make a continuous call. Thus, it is possible to improve QoE of the user and expand the markets for the PoC terminal and its services.
摘要翻译：提供一种用于在PoC系统中替换PoC终端时保证无缝会话的方法和系统，其中可以使用能够连接PoC会话的PoC兼容客户端在现有的忙PoC会话中替换当前忙的PoC客户端，从而当更换PoC客户端时，防止正在运行的PoC会话的传输媒体流丢失。该方法包括：通过任意的PoC用户，在保持会话的同时，将终端从用户终端发送到会话管理服务器的消息; 由会话管理服务器接收替换请求消息，并向要更换的终端或目标终端发送INVITE消息; 并且由目标终端通过现有会话接收INVITE消息和媒体。在需要根据PoC呼叫的媒体的变更，PoC用户请求移动性等需要更换PoC终端的情况下，允许用户进行连续呼叫。因此，可以提高用户的QoE，扩大PoC终端及其服务的市场。

摘要： Provided is a system and method for providing a converged messaging service, which can be compatibly used with or replace various services, such as an Instant Messaging (IM) service, a Short Message Service (SMS), a Multimedia Message Service (MMS), a Voice over Internet Protocol (VoIP) service, and a PTT over Cellular (PoC) service. To do this, there are defined an architecture and interfacing of a Converged Messaging Client (CMC) and a CM Server (CMS), which are elements of a converged messaging service for being compatibly used with or replacing the various services. In particular, there is suggested a method of enabling interworking between heterogeneous messaging services in an application layer by expending IP Multimedia Core Network (CN) Subsystem (IMS) technology. There is also suggested a method of defining a CM data storage for supporting the converged messaging service and managing a message and metadata stored in the defined CM data storage.

摘要： Disclosed are a method and an apparatus for managing multimedia messages. If receiving a request to set a retrieval reminder for a specific multimedia message from an MS, an MMS relay/server sets a reminder time for the specific multimedia message to a reminder time included in the request to set the retrieval reminder. If a current time corresponds to the reminder time, the MMS relay/server notifies the MS of retrieving the specific multimedia message. If receiving a request to extend an expiry time of the specific multimedia message from the MS, the MMS relay/server sets the expiry time of the specific multimedia message to an expiry time included in the request to extend the expiry time.
