Abstract

PURPOSE:To improve the working efficiency of an individual device for a mobile communication system in which the service area is divided into plural radio zones, by giving a process corresponding to the concentrated channel to the signals to plural radio base stations through a main radio base station. CONSTITUTION:A service area is divided into plural radio zones to form a major radio zone. The radio base stations 1 are installed in the radio zones; while a main radio base station 7 is set in the major radio zone respectively. Then common devices 3-5 of a transmitter/receiver for calling are provided to the station 1. At the same time, individual devices 10 and 15 are provided at the station 7 in correspondence to the radio channel which is used in the major radio zone. The signals are processed at the station 7 in correspondence to the concentrated channel for the signals to plural stations 1. Thus the working efficiency is improved by a line concentrating effect for the individual device corresponding to the channel.

と通話用送受信機の稼動率が低くなる欠点があった。In conventional mobile communication systems such as car phones, a service area is divided into multiple wireless zones, a wireless base station is placed in each wireless zone, and the number of wireless base stations is set according to the call traffic within each zone. A telephone transmitter/receiver is installed. Furthermore, in order to avoid mutual radio wave interference, the same channel is assigned to radio zones that are separated by a distance where interference does not occur, and frequencies are reused. Therefore, if the wireless zone is made smaller, the frequency can be reused more often, and the subscriber capacity can be increased. However, when the wireless zone is made smaller, the distribution of call traffic in each zone changes greatly over time due to the movement of subscribers. For this reason, if the number of radio channels of each radio base station is adjusted to match the busiest time, there is a drawback that the operating rate of the telephone transmitter/receiver becomes low.

This relates to a mobile communication system characterized in that the main radio base station is equipped with individual equipment compatible with radio channels used in large radio zones, and its purpose is to improve the operating rate of individual equipment compatible with the radio channels. It's about doing.

Further, the plurality of wireless zones constitute a large wireless zone, and a main wireless base station is installed in each large wireless zone. In this base station configuration, signals from a plurality of mobile stations within each zone are applied to a receiving/receiving device 4 via an antenna 2 and a transmitting/receiving device 3 of a radio base station 1 . The reception sharing device 4 amplifies and frequency converts the received signal, and transmits multiplexed signals from a plurality of mobile stations to the main radio base station 7 via the multiplied signal connection line 6. At the main radio base station 7, the received signals from each radio base station 1 are combined by a received signal combiner 8, and then sent to each channel-compatible individual receiving device 10 via a received signal distribution device 9. It is separated into lines and connected to the general telephone network at the exchange 14. On the other hand, the received signal to the mobile station connected from the switching center 14 to the mobile station via the connection line 13 is frequency-assigned by the channel-compatible individual transmitter 15 of the main radio base station 7 and sent to the transmit signal switcher. 12 is connected to the transmission signal combiner 11 for the corresponding unintegrated base station. The transmission signal combiner 11 multiplexes the transmission signals for the wireless base station, and the multiplexed signals are sent to the transmission shared device 5 of the wireless base station 1 via the connection line 6, and are sent to the shared transmission device 5. After frequency conversion and amplification, the signal is transmitted to the mobile station via the antenna 2 as a radio signal via the transmitting/receiving device 3.

顕著でおる。With such a configuration, the radio base station 1 is equipped with only common devices such as a transmitter/receiver splitter, a receiver amplifier, a receiver frequency converter, a transmitter frequency converter, and a transmitter amplifier, and is connected to the main radio base station. In order to perform signal processing by channel-compatible individual devices such as modulators/demodulators and channel filters located at 7,
Due to the line concentration effect, the utilization rate of individual equipment compatible with the channel is significantly improved.
