摘要： When a handover standby threshold falls below a received power of perch channel from a base station 150-1 of a communication partner, a mobile station 110 sends a handover standby operation request to a base station control apparatus 130, and notifies of history of movement of itself and receives powers of perch channels from base stations 150-2–150-4 surrounding the communication partner (mobile station information). The base station control apparatus 130 compares the mobile station information with history of mobile station information so that a handover destination candidate base station is selected and sent to the mobile station 110. The mobile station 110 switches the communication partner to the handover destination candidate base station when received power of the perch channel from the base station 150-1 falls below a handover threshold.

摘要： Priority is given to handover calls over new calls in a mobile communications system using the CDMA method. This is achieved by rejecting requests for new calls in any one of the cases in which: an uplink interference amount estimated if the requested call is accepted exceeds an interference threshold level; a downlink total transmission power estimated if the requested call is accepted exceeds a downlink transmission power threshold; and an amount of spread code resources estimated if the requested call is accepted is lower than a spread code threshold.

摘要： A base station of a mobile communication system includes a scheduler that generates uplink grant information indicating that uplink radio resources are allocated to less than or equal to a first multiplexing number of units of user equipment, a transmitter that transmits a control signal including the uplink grant information to the user equipment, and a receiver that receives an uplink signal which is transmitted by the user equipment. When a second multiplexing number being less than the first multiplexing number or more units of the user equipment exist which transmit periodically generated periodic data, and when the user equipment exists which transmits non-periodic data generated at non-periodic timing, the scheduler generates the uplink grant information indicating that the uplink radio resources are allocated to the second multiplexing number of the units of the user equipment that transmit periodic data and to the user equipment that transmits non-periodic data.
