    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: In resource measurement device 32, a measured value x of resource use condition is acquired in respect of the wireless resource to be monitored. Furthermore, in comparators 34 and 35, the measured value x is compared with the call admission threshold value x A of service A or with the call admission threshold value x B of service B, respectively. Comparison result selector 36 then selects one or other of the comparison results of comparators 34 and 35 in accordance with the type or degree of priority of the service of the call requested, identified by service identifier 33, and call admission control device 31 restricts new call admission in accordance with the selected comparison result. Thus, the call admission control method, communication system and base station device wherein deterioration of communication quality is suitably suppressed by call admission control in accordance with the service that is being utilized are provided in communication in which access is performed with shared resources.

    摘要: Resource measurement device 32 acquires a measured value x of the resource use condition in transmitting/receiving section 20 in respect of the wireless resource that is the subject of monitoring. Also, correction value calculation device 33 calculates a correction value in accordance with the number of packet users at transmitting/receiving section 20 and adjustment device 34 adjusts the call acceptance threshold value x c using the correction value, so as to obtain a corrected threshold value x c '. Comparator 35 then compares the measured value of the resource use condition x and the corrected threshold value x c ' and outputs the comparison result to call acceptance control device 31. If x ≥ x c ', call acceptance control device 31 restricts acceptance of new calls. Thus, the call acceptance control method, mobile communication system and base station device whereby deterioration of communication quality is suppressed irrespective of the switching system are provided in mobile communication in which multiple access is performed with shared wireless resources.
