Embodiment Construction

[0021] Embodiments of the present invention will be described in detail with reference to the drawings. In this description, a W-CDMA (Wideband Code Division Multiple Access) mobile communication system is taken as an example.

[0022] figure 1 is a block diagram showing the configuration of a mobile communication system according to an embodiment of the present invention. refer to figure 1 , the mobile communication system according to the present invention includes a home BTS 11 , a control device 12 and a switch 13 .

[0023] Home BTS 11 is a small base station in which a user can select an installation location, and the small base station covers a small cell. The home BTS 11 is connected to a mobile terminal (MS) 14 in a cell, and has a function of enabling voice communication and data communication between the MS 14 and other parties. The home BTS 11 is installed to cover locations that cannot be reached by radio from an operator-installed base station (not shown), fo...

Abstract

There is disclosed a base station device which can easily and surely be initialized. Base station call means performs a call operation upon a new installation. If there is an adjacent base station with which interference may be caused, the adjacent base station device is connected by radio. When the base station call means is connected to the adjacent base station device, adjacent code search means acquires an identification code from the adjacent base station device. When the base station call means cannot be connected to the adjacent base station device, code decision means arbitrarily decides its identification code. When the adjacent code search means has acquired an identification code from the adjacent base station device, the code decision means decides its identification code so that it will not be identical to the acquired code. When base station call detection means receives a call from another base station device after its identification code is decided, it responds to the another base station device. Code report means reports its identification code to the another base station device.

Description

technical field [0001] The present invention relates to base station equipment for a CDMA mobile communication system, and more particularly, to initialization when the base station equipment is installed. Background technique [0002] In general, a mobile communication system covers a wide area by arranging cells of a plurality of base stations, thereby allowing mobile phones to be used in the wide area. In addition, cells of adjacent base stations partially overlap, thereby performing uninterrupted communication. [0003] However, when interference occurs between adjacent base stations, mobile phones cannot perform correct communication. Therefore, operators should properly arrange and install base stations so that interference does not occur between base stations. In addition, various methods have been proposed for preventing interference between base stations in a mobile communication system (for example, Japanese Patent Laid-Open No. 7-30954). [0004] In recent year...
