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： A method for locating mobile terminals is provided. First, information of a home Public Land Mobile Network (PLMN) of a target mobile terminal, the location of which is to be determined, is checked in response to a location service request from a client. Then, information of a visited PLMN, where the target mobile terminal is currently located, is checked based on the checked information of the home PLMN. The home PLMN calculates location assistance information of the visited PLMN using specific location information of the visited PLMN. The location assistance information is transferred to the target mobile terminal. This allows location information of a mobile terminal to be obtained irrespective of the area or communication network where the mobile terminal is located. It is thus possible to locate a mobile terminal in an area where no location assistance information is provided.

摘要： Provided is a method and system for establishing a network-initiated PoC group session, capable of initiating establishment of a PoC session at a point of time when presence information of an opposite party intending to make a call is transited from a state in which a call can not be made to a state in which the call can be made, or at a time which a user designates in advance. The system includes at least one client that intends to initiate a session, and at least one opposite client; and a session management server for managing the session between clients belonging to an arbitrary group including the clients, determining whether an event, which meets requirements capable of initiating the session, occurs, and directly initiating the session without request of the clients when the event occurs. The server for managing the session between the clients belonging to the arbitrary group determines whether an event meeting any session initiation content stored in the server occurs, and directly initiates the session when the event meeting the session initiation content occurs.

摘要： An apparatus and method for locating mobile terminals is disclosed. A base station transmits a radio signal to mobile terminals located in a specific area, and generates- auxiliary location information for locating mobile terminals from a radio signal received from the terminals. A radio network controller receives the auxiliary location information of the terminals from the base station, and calculates locations of the terminals using the auxiliary location information. A cell broadcaster broadcasts information including assisted GPS information and an auxiliary location information request signal to the terminals located in the area. A core network manages information of mobile terminals connected to a network, and provides an interface with a location service client. This allows location of all of the terminals located in the specific area, irrespective of whether the provision of their location information is permitted, which facilitates rescue when a disaster or calamity occurs in the specific area.
