2. Description of the Related Art Conventionally, automobile telephones and mobile telephones (PHS)
(Personal Handyphone System
em: a simple mobile phone), the permanent service area of the base station is limited by base station installation cost, frequency, time slot, etc.
Usually, the mobile terminal is preferentially set from an area where the density of mobile terminals desiring to join (also referred to as “mobile communication terminal”) is predicted to be high. Here, the distribution of mobile terminals desiring to join is time zone,
Since it differs depending on the day of the week, the event, and the like, a dynamic channel assignment or the like may be performed between the constant service areas. Such a conventional technique is described in, for example, Japanese Patent Application Laid-Open No. 9-200115. That is, the prior art aims to control the antenna directivity of a base station in a wireless communication system so as to surely direct a desired terminal by simple control. In a wireless communication system that performs communication between wireless terminals, a pilot signal is transmitted from a wireless base station in all directions within the communication service area, and the wireless terminal measures reception characteristics of the pilot signal and transmits reception characteristic data to the wireless base station. This is an antenna directivity control method for a wireless base station in a wireless communication system in which the directivity is transmitted to a station and the wireless base station controls the directivity of a variable directivity antenna based on reception characteristic data. According to the antenna directivity control method of the wireless base station in such a wireless communication system, a pilot signal is transmitted from the wireless base station in all directions within the communication service area of the wireless base station, and the wireless terminal measures the reception characteristics of the pilot signal. And transmits the reception characteristic data to the radio base station, and the radio base station controls the antenna directivity based on the reception characteristic data, so that the antenna directivity of the base station can be easily controlled to a desired radio terminal direction. It is possible to control so as to be surely turned.
That is, in the present invention, the reception characteristic data obtained by the wireless terminal receiving the pilot signal transmitted from the wireless base station corresponds to the directional pattern to be formed by the variable directional antenna of the wireless base station in the direction of the wireless terminal. By using this reception characteristic data, it is possible to control the directivity of the variable directional antenna so as to surely face the wireless terminal. In comparison, the space utilization effect is sufficiently obtained, and the communication between the wireless base station and the desired wireless terminal, the communication between other wireless terminals in the same communication service area, and the wireless communication between the nearby wireless base station and Mutual interference with communication between terminals is reduced, communication quality is improved, and even in full-duplex communication, the presence of wireless terminals as seen from the wireless base station is ensured. Direction can be clearly known, the directivity can be controlled so as to be surely directed to the wireless terminal with which communication is to be performed, and even when an adaptive array antenna is used, the wireless terminal can transmit signals from the wireless base station. Since the reception characteristic data returned to the terminal corresponds to the directional beam to be formed in the direction of the wireless terminal, the directivity can be controlled by simple control so that the directional beam can be obtained. The effect is disclosed.
