摘要： A received signal of a control channel of each cell is despread by each spreading code in a correlation detector. The received level of the despread output in a window, including its peak, is measured in a level measuring part and an interference signal level outside the window is also measured. In a control part the difference or ratio between the measured received level and the interference signal level is obtained as a comparison signal for each spreading code, and the comparison signal is compared in terms of magnitude to thereby determine the visited cell of a mobile station.

摘要： Respective location registration areas (A, B, C,) in a mobile communication network include a plurality of base station service areas (a.sub.1 -a.sub.n, b.sub.1 -b.sub.n, c.sub.1 -c.sub.n). By partially overlapping the respective location registration areas, each of the respective base station service areas, for instance, (b.sub.23, c.sub.23) belong to a plurality of location registration areas (B, C). The respective base station (b.sub.23, c.sub.23) transmits all the location registration codes (B, C) together with one designated primary location registration area code (B) to be selected by a mobile station. The mobile station begins communication after registering the designated area code. When, during communication, the mobile station moves beyond the location registration area boundary, no registration is updated so long as the mobile station stays within communication with a base station transmitting the designated registered area code. When the mobile station moves out of the base station area, the registration code is updated to a new location registration area. Accordingly, the number of location registration updates due to movement of the mobile station near the boundary of location registration areas is decreased in comparison with a conventional method.
摘要翻译：移动通信网络中的各个位置注册区域（A，B，C）包括多个基站服务区域（a1-an，b1-bn，c1-cn）。通过部分地重叠各个位置登记区域，各个基站服务区域（例如，（b23，c23））中的每一个属于多个位置登记区域（B，C）。相应的基站（b23，c23）将所有的位置登记码（B，C）与一个指定的主要位置登记区号（B）一起发送，由移动台选择。注册指定区域代码后，移动台开始通信。当在通信期间移动台移动超过位置登记区域边界时，只要移动站与发送指定的注册区域代码的基站保持通信，就不更新注册。当移动台从基站区域移出时，将注册码更新到新的位置登记区域。因此，与常规方法相比，由于移动站在位置登记区域的边界附近的移动而导致的位置登记更新次数减少。

摘要： A base station includes an adjacent cell interference amount calculator and an adjacent cell interference amount notifier. The adjacent cell interference amount calculator calculates an adjacent cell interference amount caused by an adjacent cell adjacent to an original cell managed by the base station. The adjacent cell interference amount notifier notifies the mobile station of the adjacent cell interference amount. A mobile station includes radio resource associators, a selector, a propagation loss calculator, and a radio resource assigner. The radio resource associators associate a radio resource with a propagation loss in the radio packet communication. The selector selects a radio resource associator in accordance with the adjacent cell interference amount. The propagation loss calculator calculates a propagation loss in the radio packet communication. The radio resource assigner assigns the radio resource associated with the calculated propagation loss to the radio packet communication, based on the selected radio resource associator.
