Abstract
A method provides information of a client making a first response to a network-initiated push-to-talk-over-cellular (PoC) group session when the network-initiated PoC group session is established. When it is determined that an event meeting session establishment criteria occurs at a server managing a session, the session management server sends an INVITE message to at least one client to participate in the session to be established. A response signal to the INVITE message is received from the at least one client. A message containing information of the client making the first response is sent to the client making a request to establish the session. Thus, a user is informed of identification information of an initial caller and information of a requested conference, thereby enabling a PoC group call to be smoothly performed.
