Abstract: Mobile stations in communication with several base stations in a cellular CDMA system (as when undergoing soft handoff) do not use the conventional “or of the downs” rule for assessing power control commands from base stations. Mobile stations assess the link quality of the links from the base station. If any base station displays link quality above a predetermined threshold and if that base station is requesting power reduction, power is reduced by a predetermined amount, delta. Otherwise, power is adjusted up or down by an amount less than or equal to delta according to the received power control signals from each base station in conjunction with a weight determined from the signal quality of the link from each base station.

Abstract: A mobile radio apparatus of the present invention includes an apparatus body having a connector portion at one side thereof. A main display is mounted on the apparatus body. An auxiliary display includes a terminal portion and is removably connected to the side of the apparatus body with the terminal portion mating with the connector portion of the apparatus body. The auxiliary display connected to the apparatus body assists the main display in displaying data at the time of, e.g., transmission or receipt. When the apparatus is carried by the user, the auxiliary display is dismounted from the apparatus body. The apparatus therefore achieves a great display capacity without being increased in size.

Abstract: When an incoming call to a wireless communication apparatus is detected, a wireless control apparatus uses a wireless link, which has been established by previous communication, to perform succeeding communication. Examples of communication include communication of audio or data already completed, or, when there are a plurality of wireless communication apparatus, communication of control information by a wireless link established when notification of an incoming call is given to the wireless communication apparatus.

Abstract: A method for engineering management and planning for the design of a wireless communications network in three-dimensions (3-D) combines computerized organization, database fusion, and radio frequency (RF) site-specific planning models. The method enables a designer to keep track of wireless system performance throughout the process of pre-bid design, installation and maintenance of a wireless system. Using a database of information that defines the desired environment, predictions of antenna coverage, system coverage and interference, and other wireless system performance criteria, such as frame error rate and network throughput, can be made. Watch points are created to ensure, in real time, that any modifications to the design of the wireless system do not degrade the performance of the system with respect to the watch point locations.

Abstract: A mobile communication terminal includes a location information database storing location data and map data for each of the radio cell stations. When receiving a data request including an identification of a second mobile terminal from a first mobile terminal through a first radio cell station, the database is searched for first location data of the first radio cell station, second location data of a second radio cell station forming a micro cell in which the second mobile terminal is located, and map data for at least one of the first and second radio cell stations. Then the first and second location data and retrieved map data are transferred to the first mobile terminal through the first radio cell station and thereby a map and two locations corresponding to the first and second mobile terminals are displayed on screen based on the retrieved map data and the first and second location data.

Abstract: The pattern of intermittence of an incoming call signal from a communication line is reflected in the way a wireless communications apparatus such as a cordless telephone is rung. To achieve this, a master set discriminates the intermittence of an incoming call signal from a communication line in a single communication and sends a master set information in which the intermittence of the incoming call signal from the communication line is reflected. On the basis of the information reflecting the intermittence of the incoming call signal from the communication line, the slave set notifies the user of the incoming call in a way that reflects the pattern of intermittence of the incoming call from the communication line.

Abstract: A mobile communication system comprising an analog baseband processor that is configured for providing improved DC offset compensation. An offset compensation circuit of the analog baseband processor generates a first DC offset compensation signal to preset DC offset voltage of analog baseband signal when the mobile communication system is power on. A mobile station modem of the mobile communication system generates a second DC offset compensation signal to compensate for a detected DC offset voltage during operation of the mobile communication system subsequent to the DC offset voltage being preset. In addition, the offset compensation circuit re-presets the DC offset by generating a third DC offset compensation signal whenever the mobile communication system enters a predetermined mode of operation such as a “data send” mode.

Abstract: A method for extending a cell radius or access range of a base station without incurring ASIC correlator re-design. This is accomplished using a modified timing protocol that will cause signals transmitted by mobile-telephones positioned beyond the limitations of the ASIC correlator bit limitation to be received within a search window so the signals may be detected and demodulated. In one embodiment, the modified timing protocol incorporates a timing advance technique in which the base station transmits its signals at an advanced time before frame boundaries such that signals transmitted by out-of-range mobile-telephones can be received within a search window beginning at a frame boundary and spanning a time interval corresponding to the ASIC correlator bit limitation. In another embodiment, the modified timing protocol incorporates a shifted search window that begins at an advanced time after a frame boundary and spans a time interval corresponding to the ASIC correlator bit limitation.

Abstract: A method is provided for forwarding a call in a satellite communication system having a memory with a call forwarding table for storing satellite communication subscriber numbers and call forwarding numbers. The method includes the step of forming a communication path with a calling communication terminal upon detecting an incoming call. It is then checked whether a calling subscriber is a satellite communication subscriber. A subscriber number of the calling subscriber and a call forwarding number corresponding to the subscriber number is stored in the call forwarding table, when the calling subscriber is the satellite communication subscriber. It is then checked whether another incoming call to the subscriber number is detected. The other incoming call is forwarded to the call forwarding number corresponding to the subscriber number, when the other incoming call to the subscriber number is detected.
