    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 xA of service A or with the call admission threshold value xB 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 xc using the correction value, so as to obtain a corrected threshold value xc′. Comparator 35 then compares the measured value of the resource use condition x and the corrected threshold value xc′ and outputs the comparison result to call acceptance control device 31. If x≧xc′, 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.

    摘要： A downlink user data signal destined for a specific mobile station (4-1) is always transmitted from a single base station while a plurality of base stations (3-1, 3-2, 3-3, . . . ) being switched from one to another. A first downlink signal destined for the mobile station (4-1) is transmitted from one or a plurality of base stations through a first downlink radio channel (downlink A-DPCR). The transmission power of a second downlink radio channel (PDSCH, HS-SCCH) for transmitting a second downlink signal from the base station (3-1) to the mobile station (4-1) is provided with an offset relative to the transmission power of the first downlink radio channel from the base station (3-1) to the mobile station (4-1), thereby linking the transmission power of the second downlink radio channel with the transmission power of the first downlink radio channel. If the number of diversity branches, i.e., the number of base stations (3-1, 3-2) simultaneously communicating with the mobile station (4-1) on the first downlink radio channel (downlink A-DPCH) is large, the offset for the transmission power of the second downlink radio channel (PDSCH, HS-SCCH) is increased. If the number of diversity branches is small, the offset for the transmission power of the second downlink radio channel is decreased. In this way, the offset is determined. As a result, in mobile packet communication that transmits user data for a plurality of mobile stations through a single radio channel by temporally multiplexing the data, the reception quality of the second downlink signal transmitted from the specific base station (3-1) on the second downlink radio channel (PDSCH, HS-SCCH) can always properly be maintained.

    摘要： The present invention maintains the utilization of resources even in spite of the presence of a large number of communications each requiring a large amount of resources under multidimensional traffic conditions. First, the current traffic is measured. Then, a threshold value is determined on the basis of the amount of resources requested. Then, the current traffic is compared with the threshold value. If the measured traffic exceeds the threshold value, it is determined that the request cannot be accepted. In contrast, if the measured traffic is equal to or smaller than the threshold value, it is determined that the request can be accepted, and a process of accepting the resource request is executed to end the entire process.
