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.

摘要： A radio channel switching control method for a digital mobile communication system employing TDMA techniques, in which a mobile station stores the synchronized state in the current channel, switches the current channel to a new one and performs a pull-in operation for a predetermined period of time and stores the synchronized state obtained by the pull-in operation. The mobile station establishes synchronism with the new channel by repeating a sequence of steps of performing communication again in the synchronized state in the current channel and performing the pull-in operation in the stored synchronized state for the new channel. Thus, it is possible to implement radio channel switching free from momentary interruption of communication, by maintaining communication in the current channel until synchronization with the new channel is established and communication is permitted. A common reference clock is applied to a plurality of pieces of radio equipment in a base station and each radio equipment obtains a synchronized state parameter for an arbitrary slot of the channel allocated thereto. When it is judged that channel switching is necessary, the synchronized state parameter in the current channel is set in the radio equipment of the new channel, by which the radio equipment of the new channel is caused to immediately start reception in the same synchronized state as in the current channel.

摘要： Each communication is classified into any one of a plurality of communication types in advance. A plurality of threshold values used for determining whether or not the resources are to be allocated are set up in advance. The plurality of threshold values differ from each other according to the communication types and a predetermined number of divided traffic amount ranges such that a difference in ease of resource allocation between the communication types increases as a traffic value increases. When a communication connection request is made, the traffic of communication being executed is measured. A threshold value is selected according to the communication type of a communication associated with the connection request and the measured traffic. Whether or not resources maybe allocated to the communication associated with the connection request is determined based on the selected threshold value and the measured traffic.

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： 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.
