Abstract: A method to activate session control is presented. The method includes receiving a request to activate control of a collaborative session, and determining acceptance of the request to activate control of the collaborative session. The method includes sending an indication, in response to receiving the activation request, the indication indicative of the determined acceptance. The indication in the response may be indicative of an acceptance. The method may include subscribing to an event package when the indication in the response is indicative of acceptance.

Abstract: A user equipment (UE), method and system for processing session based communications, are discussed. According to an embodiment, the method includes receiving a message from a terminal that informs whether the terminal supports simultaneous PT (push-to) sessions; recognizing that the terminal supports simultaneous PT sessions according to the received message; and transporting data to one or more terminals through the server operating in B2BUA (Back-to-Back User Agent) mode, wherein a simultaneous PT session refers to a session where the server performs a PT session priority function or a PT session locking function.

Abstract: A method to transfer control is presented. The method includes sending a message requesting transfer of control of a collaborative session, and receiving notification, in response to the sent message, indicative of a transfer result of said requested transfer of control. The method may include, when the transfer result in the received notification indicates success, relinquishing control of the collaborative session. The method may include maintaining control of the collaborative session independent of the transfer result in the received notification. The message requesting transfer of control of a collaborative session may also comprises a request for media transfer.

Abstract: A method to transfer control is presented. The method includes receiving a request to transfer control of a collaborative session from a first user equipment (UE). The method includes sending a request for the transfer of control of the collaborative session in response to the received request to a second UE, and receiving, in response to the sent request to the second UE, an indication of acceptance of the transfer of control of the collaborative session. The method includes sending a notification of status to the first UE of the control of the collaborative session in response to receiving, from the second UE, the indication of acceptance.

Abstract: Session invitation method and system in a PTx communication system are disclosed. For session invitation, an inviting terminal adds first media information corresponding to session information in an invitation message and transmits it or transmits it through an RTP. Then, the first media information received by an invited terminal is checked and an invitee determines whether to accept the invitation before joining the session. When the invitation is rejected, the invited terminal adds second media information corresponding to a reason for rejection in a reject message and transmits it, or transmits it through the RTP.

Abstract: A mobile communications terminal, and method and system for controlling a floor during a PT session, are discussed. According to one aspect of the present invention, the terminal includes a PT client. The PT client includes a controller to request a user's confirmation of media burst for a PT session when the PT client receives a media burst confirmation request. The controller selectively starts encoding of media data of the PT session depending on the user's response to the controller's request.

Abstract: A method and system for addressing a unique device from an address book, the method having the steps of: receiving a message having a root token and a secondary token; checking whether the root token exists within the address book, if no, creating a record in the address book with the root and secondary token; and if yes, checking whether the secondary token exists within the address book, if yes, providing a representation of the unique device; and if no, storing the secondary token against the root token in the address book.

Abstract: A method for restricting a push-to (PT) service restricts a PT service with reference to network information. A PT client inviting to a PT session restricts an invited PT client by setting a network dependent outgoing session barring flag as ‘ON’. A PT client invited to the PT session restricts the inviting PT client by setting a network dependent incoming session barring flag as ‘ON’. The inviting PT client or the invited PT client can be selectively restricted by using information on operation conditions under which the flags are operated.

Abstract: A method and system for determining a server having a controlling function, are provided. The method includes determining which server serves most clients invited to a session among at least two different servers serving at least two clients, and designating the determined server to be a server having a controlling function.

Abstract: A method for providing a push-to (PT) service employing an invitation reservation mechanism is disclosed in which an invitation reservation function is set in a PT server so that, without an instruction of a PT client, the PT server can invite other PT clients who are available for session establishment. A method for reserving a PT service includes setting an invitation reservation function in a transmitting side PT server; requesting and receiving by the transmitting side PT server state information of PT clients who are targets for joining a session when operation conditions of the invitation reservation function are met; and transmitting by the transmitting side PT server an invite signal to the PT clients when the PT clients are in a state available for establishment of a session.
