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 call processing system and method based on an answer mode of a Push-to-Talk over Cellular (PoC) user are provided. A data format is defined, which inserts an indicator indicating a manual answer override into a payload of a Real-time Transport Control Protocol (RTCP) in a format of a new data field. When a PoC communication requester instructs the MAO to perform PoC communication regardless of an answer mode of a reception side PoC user, an auto-answer mode is immediately executed without any procedure of checking the instruction. In addition, when the reception side PoC user establishes an early session with a home PoC server in its own PoC terminal, the call processing can be performed at a quicker speed.

摘要： A method for performing session merging between PoC sessions under the environment of multiple PoC sessions is provided. A merging PoC client sends a request for the session merging with a merged session to a PoC server managing a merging session to which the PoC client belongs. The PoC server managing the merging session sends a session merge request to a PoC server managing the merged session. Negotiation of a CF (Controlling PoC Function) for managing a session to be merged is performed between the PoC server of the merging session and the PoC server of the merged session. When an entire CF of the session to be merged is selected as the negotiation between the PoC servers is completed, the PoC server of the merged session sends an UPDATE message of modified media parameters to a PoC client of the merged session. The PoC server of the merging session sends, to a PoC client of the merging session, a NOTIFY message of a merge request notifying that the PoC server of the merging session is selected as the entire CF.

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： A method allows an individual PoC client and a PoC client belonging to a specific PoC group to participate in a session as extended targets while a PoC group talk is proceeding. When the PoC client that is participating in the ad-hoc group talk intends to make the ad-hoc PoC group session ongoing by adding both a plurality of individuals and members of at least one PoC group to the existing session as preliminary talkers, the list information is obtained by identifying the group URI at the PoC server. By using SIP or Extended SIP and XCAP in this process, the PoC user that is participating in the group talk transmits the single SIP message through an ongoing session, and invites a specific PoC group and a plurality of PoC users who are designated voluntarily to the ongoing PoC group talk. Thereby, the PoC user can perform the PoC call.
