Abstract: A method for importing Digital Rights Management (DRM) data converts non-Open Mobile Alliance (OMA) DRM data to OMA DRM data for a user domain in DRM solutions. The method includes registering a local rights manager (LRM) to a domain authority or a Rights Issuer and exchanging user domain information, and creating a DRM content format (DCF) and a rights object (RO) that conform to Open Mobile Alliance (OMA) DRM standard from non-OMA DRM data based on the user domain information. A method for using DRM data includes registering the LRM, creating DCF conforming to OMA DRM standard from non-OMA DRM data, creating an RO, and transferring the DCF and RO to a DRM agent of a device.

Abstract: A method for registering a Domain Authority (DA) and a Rights Issuer (RI) for Digital Rights Management includes exchanging information between the DA and the RI. The DA and RI are registered by the exchanging of information before executing other protocol, and the method for registering can be incorporated into the following methods for implementing Digital Rights Management (DRM) with Secure Content Exchange features: (1) acquiring user domain Rights Objects (RO) by a DRM agent; (2) using the user domain RO by a 2.0 DRM agent; and (3) using imported user domain RO by a 2.0 DRM agent.

A method of improving the boot speed of a mobile communication terminal equipped with a UIM according to the present invention includes: a) handing over controllership, by a user interface (UI) task responsible for an initial UI process, to a UIM task in a process of reading a phonebook stored in the UIM during booting; b) setting parameters necessary for reading the phonebook stored in the UIM by the UIM task which has taken over the controllership from the UI task; c) reading records composing the phonebook one by one and copying each record into RAM by the UIM task after setting of the parameters is completed; and d) handing over the controllership to the UI task by the UIM task after the UIM task copies the records into the RAM.

Abstract: A method of delegating user domain management authority is disclosed to provide flexible and continuous user domain management. According to this method, user domain management authority may be delegated from a first device in the user domain to a second device in the user domain. Delegation of user domain management authority may be performed through consultation with a delegation agent such that delegation may occur when the first device having user domain management authority is lost, unavailable, or otherwise inoperable by a user. Delegation of user domain management authority may include transferring user domain management information, such as user domain policy, user domain master key, and user domain key chain, from the first device to the second device. Once the second device receives user domain management information, user domain management authority of the first device may be discharged and notice may be sent to devices in the user domain.

Abstract: Disclosed are a system and a method of controlling an audio output in a mobile communication terminal, and more particularly to a system and a method of controlling an audio output of mobile communication terminal, wherein when a broadcasting channel is changed, an audio signal of the mobile communication terminal is not outputted for a preset time or in an ineffective channel from which a broadcasting does not come through. The mobile communication terminal having a television function according to an embodiment of the invention is characterized in that when a broadcasting channel is changed, a video signal is outputted and at the same time an audio signal is not outputted by turning off the amplifier for a preset time, and when the preset time lapses, the amplifier is turned on and thus the audio signal is outputted.

Abstract: A packet switched radio telecommunication system supporting hard handover adapts Always_on technology to a link between a target packet data serving node (PDSN) and a support PDSN. The support PDSN assigns a temporary IP address to a mobile terminal in its service area, and transmits handover data and the mobile terminal's temporary IP address to the target PDSN via a direct link when the mobile terminal leaves the service area. The target PDSN, upon receiving a registration request for the temporary IP address from the mobile terminal moved to its service area, temporarily registers the temporary IP address in an IP pool. The target PDSN receives down-link frame data for the mobile terminal at the temporarily registered IP address from the support PDSN via the direct link. A new temporary IP address is assigned by the target PDSN when data transmission/reception is complete to the mobile terminal.

Pilot symbols are mapped to pilot tone frequencies assigned to terminals, and even-numbered or odd-numbered pilot symbols are phase-rotated to be orthogonal. An apparatus for transmitting pilot symbols in an OFDM-based communication system is provided. A tone mapping unit maps pilot tone frequencies assigned to terminals onto pilot symbols to be transmitted, and a phase rotation unit phase-rotates either even-numbered or odd-numbered pilot symbols. An apparatus for transmitting pilot symbols in an OFDM-based communication system is provided. A tone mapping unit maps pilot tone frequencies assigned to terminals onto pilot symbols to be transmitted, and a transmission unit stores a signal in a buffer and transmits a first portion of the signal in a first pilot symbol and a second portion of the signal in a second pilot symbol.

Abstract: A method is disclosed for transmitting a packet from a correspondent node to a mobile node when the mobile node moves from a home network to an external network equivalent to the correspondent node's local network. The method may include securing a Care Of Address (COA) for the mobile node. The COA may be used to forward a packet intended for the mobile node by a home agent in the home network. The method may also include obtaining the COA at the home agent to update binding information on the mobile node, transmitting the updated binding information to a correspondent node, and setting a target IP address for the packet transmitted by the correspondent node. The target IP address may be the COA of the mobile node when the correspondent node's local network is the same as the external network where the mobile node is located.
