摘要： A system and method of a multimedia Push-To-Talk (PTT) over Cellular (PoC) box service is provided which can reflect dynamic requests of a user using a function for interworking with a PoC server and an Extensible Markup Language (XML) Document Management Server (XDMS) in a PoC system. In a method for providing the PoC box service, the PoC XDMS stores various information about a type of media to be stored by a PoC user, a PoC box type, and a connection address after a service request expires. An associated service is implemented by Session Initiation Protocol (SIP) technology between the PoC server and a PoC client and by interworking with the PoC server and the XDMS.

摘要： A mechanism to enable multiple message threads management in the context of the Converged IP Messaging (CPM) service and in the context of CPM inter-working with SMS is provided. A CPM user can simply start a message-based conversation with another CPM or Short Message Service (SMS) user without explicitly establishing a session beforehand. All messages that belong to a given conversation are displayed in the corresponding conversational view (i.e. window) in the CPM user device, even if the conversation is stopped and restarted at a later time, and even if there are multiple message threads available (currently active or stored) in the CPM device. Message structures and behavior of the CPM system elements to enable the functionalities above as well as a mechanism makes the message threads management possible even between a CPM user and an SMS user are also provided.

摘要： An embodiment of the present invention relates to a combined accelerometer and gyroscope system. The combined accelerometer and gyroscope system includes a combined accelerometer and gyroscope for maintaining vibration of a mass body at a constant amplitude using an applied drive voltage, and detecting vibration signals in directions of an acceleration axis and an angular velocity axis. An acceleration axis vibration signal obtainment unit obtains the vibration signal in the direction of the acceleration axis. An amplitude maintenance control unit outputs an acceleration axis vibration maintenance control signal using the vibration signal. An acceleration axis driving input unit receives a voltage signal from the amplitude maintenance control unit and applies the voltage signal to the combined accelerometer and gyroscope. An angular velocity axis vibration signal obtainment unit obtains the vibration signal in the direction of the angular velocity axis. A force balance control unit outputs an angular velocity axis vibration maintenance control signal using the vibration signal received from the angular velocity axis vibration signal obtainment unit. An angular velocity axis driving input unit receives a voltage signal received from the force balance control unit and applies the voltage signal to the combined accelerometer and gyroscope.

摘要： Disclosed is a method and system for transferring and applying a floor control scheme when a Push-To-Talk (PTT) over Cellular (PoC) session is established between PoC clients supporting various types of floor control schemes (e.g., media burst control schemes). According the method and system, when a PoC client providing Open Mobile Alliance PoC multimedia communication service supports a plurality of floor control schemes and there is no floor control scheme appointed to be supported in a session, a floor control scheme requested by a PoC session establisher is transferred through a PoC session establishment procedure and is applied to the session.

摘要： A method in which a delegated client sends a request message containing operation information, a delegated client identity (ID), and a delegating client ID at the time of sending an operation request to a target system. The target system receives the request message and delegation-authorizes the delegated client by examining whether the delegating client is authorized to perform the operation requested by the request message and also whether the delegating client has delegated the authority to perform the operation to the delegated client sending the request message using the delegating client ID included in the request message. A new header is provided which includes ID information of the delegating client in the request message. When receiving the request message, the target system performs a procedure for authenticating and authorizing not only the delegated client but also the delegating client using the delegating client ID.
