Disclosed is a method for delivering a message in a converged IP messaging (CPM) server. The message delivery method may include determining whether to reject a CPM message based on the access policy if the CPM message is received; checking a user preference of a target terminal to determine processing of the CPM message if it is determined that the CPM message is not rejected; determining whether to reject, defer or store the CPM message based on the user preference if the target terminal is not registered or in an unreceivable state; storing the CPM message in a queue if it is determined that a transmission of the CPM message is deferred; determining whether to discard or store the CPM message based on the user preference if a timer for the CPM message is expired; requesting to store the message to a message storage server if it is determined to be stored; receiving a response message including information on the stored message from the message storage server; and transmitting a message including the information on the store message to the terminal.

A PT (Push-To) service among SIP based session services, and particularly, a method and terminal for establishing a PT session in order to allow a certain user to use a PT box service under control of a PT server in a SIP (Session Initiation Protocol) based service, are discussed. According to an embodiment, the method of providing a Push-To (PT) box service, includes storing, in a PT server, PT box setting information of a terminal; receiving, by the PT server, a session invitation directed to the terminal; and determining, by the PT server, a routing of the session invitation to a PT box for the terminal based on at least the PT box setting information.

A system and method for changing a value of a talk burst control timer, are provided. According to an embodiment, there is provided a method of controlling talk burst timer operations for a terminal that communicates with a network, the method performed by the network and comprising: receiving at least one talk burst request from the terminal; and sending, to the terminal, at least one time value for at least one talk burst control timer of the terminal, wherein the time value is decided with consideration of network environment information, and wherein the time value is sent by using a device management (DM) provisioning method.

A method and terminal for processing media data for a Session Initiation Protocol (SIP) based session service, in which a terminal checks a talk burst revoke reason code included in a talk burst revoke message received from a server to selectively perform either transmission or discard of remaining buffered media data depending on the checked talk burst revoke reason.

A PT (e.g., Push-To-Talk, Push-To-View or Push-To-Data) service, and more particularly, to a method and device for controlling a floor (talk burst authority, permission to send media burst, etc.) in a PT service, are discussed. According to an embodiment, the method for controlling a state of a Push-To (PT) server, includes starting, by a PT server, a stop talking (T2) timer which is a type of media burst control timer that operates with respect to a terminal having permission to send a media burst; checking, by the PT server on expiry of the T2 timer, whether a media burst release message was already received while the T2 timer was running; and entering, by the PT server, a media burst idle state if the media burst release message was already received as a result of the checking step.

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.

Disclosed is a method for transmitting a signal in a mobile communications system using a plurality of transmit/receive antennas. A method for transmitting a signal in accordance with an embodiment of the present invention comprises the steps of: a receiving end's calculating a signal to interference noise ratio (SINR) with respect to every antenna pairs configuring STTD pairs to be transmittable from a transmitting end; feedbacking information indicating an antenna pair having the greatest SINR to the transmitting end; and the transmitting end's performing a D-STTD transmission through the antenna pair determined by the feedbacked information. A method for transmitting a signal in accordance with another embodiment of the present invention comprises the steps of: a receiving end's feedbacking information of an antenna pair and/or an eigenvector (weight vector) of a channel matrix with respect to transmit antennas included in the space-time multiplexing (STTD) pair to a transmitting end; and the transmitting end's forming beam by multiplying a symbol with respect to each STTD pair by the eigenvector, and thereafter transmitting the beam through each transmit antenna (in case of using two antennas) or a transmit antenna pair (in case of using more than four antennas) determined by the information of the antenna pair.

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.

Disclosed are an XML document management method for cancelling a specific past operation, and a system using the same. The method comprises identifying an original operation to be cancelled, identifying an XML resource to be cancelled, identifying a previous value of the XML resource to be cancelled, identifying a next value of the XML resource to be cancelled, configuring a cancel operation, and applying the cancel operation to the XML resource to be cancelled.
