摘要： A speech freeze-out method in a communication system for transmitting speech information, which is sent from public telephone terminals (1) to a control center (5) through voice channels, from the control center (5) to a base station (8) through time division multiplexing radio frequency channels (6), and from the base station (8) to mobile stations (17) through transponders (13). The freeze-out processing is carried out when the control center (5) feeds the speech information to the time division multiplexing radio frequency channels (6) so that the number of transmission channels from the base station (8) to the transponders (13) is limited within an upper limit value. The control center (5) sequentially detects the presence and absence of a speech spurt in each frame of respective voice channels during each time slot of the time division multiplexing radio frequency channels, counts the number of the channels including the speech spurt, and performs the speech freeze-out processing when the count value exceeds the upper limit value. The number of transmission channels from the base station (8) to the transponders (13) is positively limited within the upper limit value.

摘要： The object of the invention is to prevent reduction of the system capacity caused by the use of a channelization code belonging to the secondary scrambling code. Instead of trying to select a channelization code belonging to each of the primary and secondary scrambling codes for one cell in a conventional manner, selection of a channelization code belonging to the primary scrambling code is tried sequentially for a plurality of cells (S02, S04). If the selection of the code has been failed, it is determined whether selection is tried again under a different condition (S06). Then, when trying again, selection of a channelization code belonging to the secondary scrambling code is tried sequentially for the plurality of cells (S07, S09).
摘要翻译：本发明的目的是防止由于使用属于二次扰码的信道化码引起的系统容量的降低。代替尝试以常规方式选择属于一个小区的每个主要和次要扰码的信道化码，对多个小区（S02，S04）依次尝试属于主扰码的信道化码的选择，。如果代码的选择失败，则确定是否在不同的条件下再次尝试选择（S06）。然后，当再次尝试时，针对多个小区顺序地尝试选择属于次扰码的信道化码（S07，S09）。

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.
