Abstract: Methods, systems and data structure for storing and managing information in a wireless network are described wherein fixed resources in the system are stored in a database in a hierarchical directory structure according to the location of each fixed resource. Each level of the directory structure represents a geographical area in which a fixed resource is located. A mobile user submits a query for the location of the nearest fixed resource having certain properties. The system determines the location of the mobile user and then searches the database for the requested fixed resource that is nearest to the mobile user. When the fixed resource is identified, data regarding its location is transmitted to the mobile user. In addition, specific directions as to how to get to the location of the fixed resource from the location of the mobile user may be provided.

Abstract: A cellular phone includes a first case and a second case, which are connected in a foldable manner through a hinge. When the cellular phone is in a folded state, a second display unit displays an image with the side (upper side) closer to the hinge as the upper side. Accordingly, the user can hold the second case of the cellular phone in his/her hand regardless of whether the cellular phone is in a folded state or in an open state. The user can easily switch between a folded state and an open state with respect to the first case and the second case.

Abstract: A system dynamically discovers the geographic location of entities of a computer network. A network entity is configured to include a location determination engine and a radio frequency (RF) receiver unit. A plurality of RF base stations are disposed in the area proximate to the network entity. Each RF base station has a beacon for transmitting a radio frequency (RF) signal encoded with the location, e.g., the physical coordinates, of the respective RF base station and the time of transmission. The encoded RF signals are received by the RF receiver unit at the network entity and passed to the location determination engine, which uses the received information to compute its location. The location determination engine then reports its location by loading the computed location into a network message and transmitting that message to a central repository.

Abstract: A device for presenting information on a mobile includes mobiles and terminals interconnected intercommunicably through communication means, wherein a terminal transmits, to the mobile concerned, mobile identification data on a mobile to which a request for mobile information is to be made, request content identification data representing the contents of mobile information to be requested, and terminal identification data on the terminal being the presentee to which the requested contents is to be presented. The mobile acquires mobile information requested by the terminal and sends it to the terminal being the presentee.

The portable communication device comprises a first housing extending in the longitudinal direction thereof, a second housing rotated about a first hinge axis perpendicular to the longitudinal direction of the first housing such that the angle between a bottom surface of the second housing and a corresponding top surface of the first housing varies, and a cylindrical hinge housing disposed at one end of the first housing while a portion of the cylindrical hinge housing protrudes outward from the first housing. The first hinge axis extends in the diametrical direction of the cylindrical hinge housing wherein the second housing is attached to the cylindrical hinge housing while the second housing is rotated about the first hinge axis. The cylindrical hinge housing has a second hinge axis extending in the axial direction of the cylindrical hinge housing so that the second housing can rotate about the second hinge axis.

Abstract: A method of controlling noise in a pulse width modulation circuit includes varying a sample frequency and a range of information levels, wherein each sample within a data sample stream at the sample frequency represents a level within the range of information levels, to shift in frequency noise generated at the sample frequency during encoding of the data sample stream into pulse width modulated patterns.

Abstract: In a method for the continuous real time tracking of the position of at least one mobile object in a defined multidimensional space, at least one mobile transmitter module is attached to at least one mobile object and the signals from the at least one module are received by a stationary receiving and signal processing network and then centrally processed. The signals emitted by each transmitter module are electromagnetic waves sent within a frequency band range using time division multiplexing techniques.

Abstract: In a satellite system, a time frame to be used for establishing a time correlation between the satellite system and a ground station is inserted between the transmission frames at an arbitrary timing. The ground station computes the time at which the data was generated in the satellite system from this time frame and establishes a time correlation with the satellite time by using only this time frame.

Abstract: An apparatus in one example comprises a call control component that sets a call category for a call to indicate that the call terminates at an announcement server component prior to connection with a called communication device. Upon receipt of an answer message from the announcement server component, the call control component drops the answer message based on the call category.

Abstract: A mobile terminal for displaying an auxiliary display area and a method thereof. All information except for the state information (e.g., reception sensitivity and battery state) and operation information (e.g., background image, call time, and menu list) of a mobile terminal can be displayed in the auxiliary display area. The mobile terminal sets the auxiliary display area differently depending on the characteristics of information to be displayed and displays it with corresponding information. Accordingly, the utilization of the auxiliary display area is increased.

Abstract: A method of providing location-based services for a mobile unit operating in a wireless network including network structures. The method includes receiving an identifier associated with the mobile unit. The method also includes monitoring a location of the mobile unit using the identifier and a network-assisted location finding system to identify a crossing of a service zone boundary by the mobile unit.

Abstract: A correct escape mechanism is determined according to interference type. Transmission is arranged so that interference may be measured at all time slots as needed to compute a measure of variance in interference in time slots. If the variance is above a predetermined value, time division duplex escape mechanisms are employed. If the variance is below a predetermined value, appropriate escape mechanisms are employed depending on whether the escape mechanism is being implemented during an uplink or downlink. Interference causing FDD WTUs may be handed over to carrier bands to control interference experienced by TDD users.
