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： Disclosed is a multimedia message service method and system for sharing and searching for multimedia messages stored in an MM box. The MMS client has the possibility to associate an access mode (“public”, “restricted”, or “private”) to any multimedia message stored in or uploaded to an MM box. When a multimedia message is permitted to be shared, the MMS clients who have been granted access to the multimedia message can be notified of the shared multimedia message. When the MMS client requests to view or retrieve a multimedia message, the MMS relay/server checks if the MMS client has been granted permission to access to the multimedia message. If the MMS client has been granted permission to access to the multimedia message, the MMS relay/server allows the MMS client to access the multimedia message.

摘要： An apparatus and method determines soft handover in a Code Division Multiple Access (CDMA) mobile communication system supporting a Multimedia Broadcast Multicast Service (MBMS) service. In the CDMA mobile communication system supporting an MBMS service, when a User Equipment (UE) moves to a region where it can receive data from a plurality of Node Bs, the UE determines by itself whether to perform soft combining on MBMS data received from the Node Bs. Therefore, even though an MBMS user moves from an existing cell to a new cell, the MBMS service is stably provided, contributing to the convenience of the user.

摘要： an Disclosed are a method and an apparatus for providing a PoC service in a radio communication system supporting a BCAST service. For the PoC service in the radio communication system supporting the BCAST service, a first terminal joining the PoC service through the BCAST service transmits user data for the PoC service over an uplink dedicated bearer, and the user data reach a PoC server, which controls the PoC service, over the uplink dedicated bearer. The PoC server transmits the user data to a BCAST server controlling the BCAST service and, from the BCAST service server, the user data reach plural second terminals joining the PoC service over a downlink shared bearer. In this way, radio resources can be efficiently used when the PoC service is performed in a random area, and an a BCAST service operator d a PoC service operator is provided.

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.
