    • A location system comprises a communication terminal for transmitting a location request specifying a target mobile terminal and a type of location information, and a location network. In response to the location request, the location network produces current location information of the target mobile terminal if the type of location information of the received request specifies current location information and transmits the current location information to the communication terminal and stores the last known location information in a memory as last known location information of the target mobile terminal. If the type of location information specifies last known location information, stored last known location information of the target mobile terminal is copied from the memory and transmitted to the communication terminal if the location request is verified by a privacy check and if the stored information is reusable.
    • 位置系统包括用于发送指定目标移动终端的位置请求和位置信息的类型的通信终端以及位置网络。 响应于位置请求,如果接收到的请求的位置信息的类型指定了当前位置信息,则定位网络产生目标移动终端的当前位置信息,并将当前位置信息发送到通信终端,并且存储最后的已知位置信息 在作为目标移动终端的最后已知位置信息的存储器中。 如果位置信息的类型指定最后一个已知的位置信息,则如果通过隐私检查验证位置请求并且所存储的信息是否可重用,则将存储的目标移动终端的存储的最后一个已知位置信息从存储器复制并发送到通信终端 。

    • A radio communication apparatus in a radio packet communication system constituted by a plurality of radio stations and having a plurality of radio channels is provided. To allow radio stations belonging to different radio links to directly communicate with each other, when a packet as data is to be transmitted, a channel control section (101) inquires of a channel registration section (102) about a radio channel used for reception by a radio station corresponding to the destination address in input transmission data, and a radio channel used for packet transmission is selected. The packet is then transmitted from a transmission/reception section (103) via the selected radio channel. When a packet is to be received, the radio channel in the transmission/reception section (103) is switched to the self-station radio channel stored in a self-station channel storage section (104).
    • 提供了由多个无线电台构成并具有多个无线信道的无线分组通信系统中的无线通信装置。 为了允许属于不同无线电链路的无线电站彼此直接通信,当作为数据的分组将被发送时,信道控制部分(101)向信道注册部分(102)询问关于用于接收的无线电信道, 选择对应于输入发送数据中的目的地地址的无线电台,以及用于分组发送的无线电信道。 然后经由所选择的无线电信道从发送/接收部分(103)发送分组。 当要接收分组时,发送/接收部分(103)中的无线电信道被切换到存储在自身站信道存储部分(104)中的自站无线电信道。

    • In each cell of a plurality of cells of a mobile communication network assigned with a predetermined number of radio channels, a base station allocates to a call one of the radio channels according to autonomous channel reuse partitioning as a communication channel on transmitting messages to and from a mobile unit which is currently present alive in the cell under consideration. For use as the communication channel, the radio channel should preferably have a base and a mobile carrier to interference ratio which is equal to or greater than a first allocation threshold level determined by a sum of a power control margin for base and mobile transmission powers and a second allocation threshold level determined to be sufficient for transmission of the messages. If such a radio channel is not available, another of the radio channels is used as the communication channel that has the base and the mobile carrier to interference ratios both equal to or greater than the second allocation threshold level. It is thereby rendered possible to control the mobile transmission power after allocation of the communication channel and furthermore the base transmission power.
    • 在分配有预定数量的无线电信道的移动通信网络的多个小区的每个小区中,基站根据自主信道重用分配来分配一个无线电信道,作为向和/ 当前存在于正在考虑的单元中的移动单元。 为了用作通信信道,无线电信道应该优选地具有等于或大于由基站和移动发射功率的功率控制余量之和确定的第一分配阈值水平的基站和移动载波干扰比,以及 被确定为足以传送消息的第二分配阈值级别。 如果这样的无线电信道不可用,则另一个无线电信道被用作具有等于或大于第二分配阈值电平的基站和移动载波干扰比的通信信道。 由此,能够控制分配通信信道之后的移动发送功率,进一步控制基站发送功率。
