摘要： A content distribution system uses a PtP (point to point) channel (individual channel) or PtM (point to multi-point) channel (common channel) as a radio channel of a predetermined type so as to distribute a broadcast content as communication data to a user terminal as a mobile station. The user terminal receives the same content distributed from a broadcast content server by the PtP channel. Here, if the total of the downlink transmission power of the PtP channel is greater than the downlink transmission power of the PtM channel when the content is distributed to the user terminal by the single PtM channel, a base station or a base station control device judges that the radio channel is to be switched from the PtP channel to the PtM channel. Similar judgment is made when switching from the PtM channel to the PtP channel is performed. Thus, it is possible to switch the radio channel type used for the broadcast-type service without lowering the use effect of the radio resources.
摘要翻译：内容分配系统使用PtP（点对点）信道（单独信道）或PtM（点对多点）信道（公共信道）作为预定类型的无线电信道，以将广播内容分发为通信数据用户终端作为移动台。用户终端通过PtP信道接收从广播内容服务器分发的相同内容。这里，当通过单个PtM信道将内容分发给用户终端时，如果PtP信道的下行链路发送功率的总和大于PtM信道的下行链路发送功率，则基站或基站控制装置判断无线电信道将从PtP信道切换到PtM信道。当从PtM通道切换到PtP通道时，进行类似的判断。因此，可以在不降低无线电资源的使用效果的情况下切换用于广播型业务的无线电信道类型。

摘要： In a content distribution system, when distributing content to a plurality of user equipment, a multicasting channel is assigned between the user equipment and the distribution system, content being multicasted using this multicasting channel. If a user equipment fails to receive distributed content, the radio network controller allocates an individual channel between the user equipment and the distribution system to perform re-distribution of the content in response to the user's request.

摘要： A transmission power control apparatus capable of reducing interference, in a mobile communication adopting the CDMA system, with other communications by decreasing transmission power in one direction of channel taking communication quality of other channel of direction into account is provided. A reverse channel error rate judgment section for judging a communication quality of the reverse channel by a reverse channel frame error rate detected and a forward channel error rate judgment section for judging a communication quality of the forward channel by a forward channel frame error rate reported by a mobile terminal are provided in the radio base station. The forward channel error rate judgment section, when detected, reports the state of communication degradation of own direction of channel to the reverse channel error rate judgment section which, in turn, controls to instruct the mobile terminal to decrease transmission power of the reverse channel. When communication degradation is detected by the reverse channel error rate judgment section, the state is reported to the forward channel error rate judgment section to control to decrease transmission power of the forward channel.

摘要： A mobile communication system provides different types of radio communications using a same mobile terminal service. One service area is provided by conventional base stations by which the mobile communication network is carried out, and another service area is provided by a fixed network terminal device, such as a cordless home phone connected in a public fixed communication network, and the mobile terminal device can be used in both service areas by switching over internal call circuit appropriately. On the other hand, a call directed to the mobile terminal device is suitably routed to the mobile terminal device in either of the service areas by a terminal device switching circuit in the mobile communication systems having a database on which location information of the mobile terminal device are registered.
