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.

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： 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： 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 signal transmission method checks, when detecting an occurrence of a communication request, whether the communication request is a high speed communication (step S302). In the case of the high speed communication, it checks whether the number of current high speed communications (m) plus one is greater than the upper limit (mmax) of the high speed communication (step S312). If greater, it cancels the request as a call loss (S316), and sets to a variable a the ratio (h) of the rate of the high speed communication to that of a low speed communication. If the communication request is the low speed communication, it sets one to the variable a (step S304). It compares n plus a with nmax (step S306), where n is the total number of all the current communications, a is the value associated with the communication request, and nmax is the upper limit of the number of communications acceptable in a bandwidth, all of which are expressed in terms of the number of the low speed communications. If n plus a is greater than nmax, the communication request is canceled as a call loss (S316). Otherwise, the total number of the current high speed communications (m) and the total number of all the current communications (n) expressed in terms of the number of the low speed communications are updated, and a channel is assigned to the communication request (step S310).

摘要： Disclosed is a mobile communication system whereby, to reduce the connection time, a mobile station closely located to a base wireless station is permitted to continue to use a common channel for exchanging signals, and to suppress an increase in interference, an individual channel is set for a mobile station located near the edge of a cell, and to obtain a stabilized communication quality and to prevent an increase in the connection time, the probability that the transmission power will reach an upper limit is reduced. When communication between a mobile station and a wireless base station is started, the wireless base station measures the transmission power and the communication quality in the communication with the mobile station and the utilization ratio for a common channel, and compares the obtained values with predetermined threshold values. When the obtained values are lower than the threshold values, the wireless base station continues to use the common channel for signal transmission/reception. On the other hand, when the obtained values exceed the threshold values, the wireless base station sets an individual channel and sets a wireless channel so as to be capable of the continued use of the individual channel for the exchange of signals.
