When there is the base station ID of the "transmission-stop" instruction, it is judged that a mobile station exists in a transmission control zone, it comes into a state in which transmission is stopped, before coming into reception state. While when there is no the base station ID of the "transmission-stop" instruction, it is judged that a mobile station exists out of a transmission control zone, thus being selected a transmission destination. There is judged whether or not warning information is incorporated in base station ID of the transmission destination base station.Type: GrantFiled: April 15, 1998Date of Patent: December 19, 2000Assignee: NEC CorporationInventor: Narihira Takemura

Patent number: 6160496Abstract: A device and method that allows a pilot to switch between communication and navigation inputs without disrupting the pilot's current task. An audio selector panel has inputs for at least two communication transceivers and outputs for at least a pilot's headset. A rotary switch on the face of the audio selector panel selects which inputs are connected to which outputs. The audio selector panel further includes a remote swap switch that is mounted in a position in which the pilot can activate the switch without removing his/her hands from a yoke or diverting his/her eyes to the switch. The activation of the remote swap switch causes the audio selector panel to switch between the communication and navigation inputs. In this way, the pilot can switch communication and navigation inputs without disrupting the current task of the pilot.Type: GrantFiled: May 10, 1999Date of Patent: December 12, 2000Assignee: PS Engineering, Inc.Inventor: Mark S.

Patent number: 6111867Abstract: A system implements a method of allocating a mobile communications device, such as a mobile end station, to packet channels, such as packet control channels within a cell. A mobile communications device identifies for access a packet channel by executing an algorithm, such as a hashing algorithm. The mobile communications device then reads a loading message broadcast for that packet channel. If the loading message indicates to the mobile communications device that another packet channel or PCCH should be sought, the mobile communications device tunes to a beacon frequency and reads information for each packet channel or PCCH broadcast at the beacon frequency. The mobile then tunes to a suitable channel. The processing to select a suitable channel is accomplished in the mobile communications device, thereby relieving other system elements, such as the mobile data base station (MDBS) from carrying out that processing and reducing the information traffic on overloaded channels.Type: GrantFiled: December 12, 1997Date of Patent: August 29, 2000Assignee: Nortel Networks LimitedInventors: Karl D.

Patent number: 6081727Abstract: In a mobile communication network including a radio base station (50.sub.1) having a service area and a mobile terminal (13) present within the service area, a transmission power control system includes in the fixed station an abnormal terminal detecting part (48, 49, 52) for detecting the mobile terminal as an abnormal terminal when the mobile terminal does not decrease the transmission power after a transmission power control part (37, 48, 52) transmits the mobile terminal with a control signal requesting a decrease of transmission power of the mobile terminal. The abnormal terminal detecting part transmits, when detects the abnormal terminal, the abnormal terminal with a forced communication-disabling signal which is for use in the abnormal terminal in forcedly disabling communication when the abnormal terminal receives the forced communication-disabling signal.Type: GrantFiled: May 18, 1998Date of Patent: June 27, 2000Assignee: NEC CorporationInventor: Seiji Kondo

Patent number: 6075994Abstract: A method and an apparatus for dynamically determining the optimal communication mess age bundle size for a communications system based on system resource utilization parameters, such as CPU utilization, message processing latencies, and paging message response delays within the system. At low loads, a bundle size of 1 message is selected. Under such conditions, paging messages are broadcast to mobile units in real time, with no waiting. As the mobile station termination activity increases and the round-trip-paging response delay exceeds a threshold, the bundle size is increased to reduce the processing overheads, which, in turn, reduces the end-to-end system delay for paging. As the paging message traffic decreases, the bundle size is reduced to decrease the delay introduced by bundling, which, in turn, reduces the round-trip-paging response delay.Type: GrantFiled: May 29, 1998Date of Patent: June 13, 2000Assignee: Lucent Technologies, Inc.Inventor: Kabekode V.

Patent number: 6052578Abstract: Upon detecting a contention between a call request and an active call (404), the call request is added to a busy queue as a contention busied call (412) and at least one logical link is created between the busied call and the active call(s) giving rise to the contention (414). When the active call(s) terminate (502), the at least one logical link is used to identify those busied calls that may be converted to active calls (514), thereby reducing delays associated with the conversion of contention busied calls.Type: GrantFiled: June 20, 1997Date of Patent: April 18, 2000Assignee: Motorola, Inc.Inventors: David E.

Patent number: 6035204Abstract: A cordless telephone releases a telephone call, in case that a handset unit is engaged in the telephone call over a predetermined time even though a telephone conversation has been completed. During the telephone conversation, a base unit periodically transmits busy state inquiry data to the handset unit, and checks whether response data thereto is received or not within a predetermined time. If the response data is not received within the predetermined time, the speech loop is automatically cut off. Therefore, in case that the handset unit misoperates due to the damage or the discharge of the battery, the base unit forcefully releases the call so that the user may make a telephone call with the base unit or another handset unit.Type: GrantFiled: October 28, 1997Date of Patent: March 7, 2000Assignee: SamSung Electronics Co., Ltd.Inventor: Eui-Jae Lee
