US 7,623,883 B2 · Method and system for identifying respondent client in push-to-talk over cellular network

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.

Dependent claims

A method for providing information of a client making a first response in a push-to-talk-over-cellular (PoC) network, the method comprising the steps of:

sending, by a session management server, an INVITE message to each of a plurality of clients to participate in a session to be established, when it is determined that an event meeting session establishment criteria occurs;
receiving a first response signal to the INVITE message from one of the plurality of clients;
and
sending a message including information of the one of the plurality of clients making the first response to at least another of the plurality of clients, to request establishment of the session,
wherein the INVITE message includes information on a group identity of an originating side client of a session establishment requester and information on an identifier of a network-initiated session establishment requester.

A system for providing information of a client making a first response in a push-to-talk-over-cellular (PoC) network, the system comprising:

an initiating client for requesting that a session be established;
at least one participating client for participating in the session;
and
a session management server for managing the session between the initiating client and the at least one participating client, by sending an INVITE message to the initiating client and the at least one participating client to participate in the session to be established when an event meeting session establishment criteria is met, and sending a first response message including information on a first one of the initiating client and the at least one participating client to respond to the INVITE message to at least one other client that has been sent the INVITE message;
wherein the INVITE message comprises information on a group identity of an originating side client of a session establishment requester, and an identifier of a network-initiated session establishment requester.
