Embodiment Construction

[0039] Typical embodiments of the present invention are described below with reference to the drawings.

[0040] (1) First exemplary embodiment

[0041] figure 2 A configuration example of a wireless communication system according to the present exemplary embodiment is shown. The wireless communication system according to the present exemplary embodiment includes a wireless base station (first wireless base station) 1-1 and a wireless base station (second wireless base station) 1-2 which is an adjacent wireless base station adjacent to the wireless base station 1-1. The radio base station 1-1 includes a communication unit 1A and a control unit 1B. Since the present exemplary embodiment is characterized by the structure of the wireless base station 1-1, the description of the structure of the wireless base station 1-2 is omitted.

[0042] The communication unit 1A is a part that communicates with the wireless base station 1-2. In the case where the wireless base station 1-1 ...

Abstract

Provided is a wireless base station which is capable of increasing an area of overlap between a wireless base station cell and an adjacent wireless base station cell, before the wireless base station narrows the cell range or reduces the transmission power. A wireless base station (1-1) is provided with a communication unit (1A) and a control unit (1B). Prior to the wireless base station (1-1) narrowing the cell range or reducing the transmission power, the control unit (1B) transmits, via the communication unit (1A), to a wireless base station (1-2) adjacent to the wireless base station (1-1), an instruction signal which instructs that the cell range of a wireless base station (1-2) be expanded in the direction of the wireless base station (1-1).

Description

technical field [0001] The present invention relates to a wireless base station, a core network device, a wireless communication system and a wireless communication method. Background technique [0002] Today, wireless communication networks using wireless terminals and wireless base stations have become popular, and communication services that enable wireless terminals to perform wireless communication at any time, at any place, and with anyone are provided. In addition, since the content of communication services involves every day, wireless base stations need to update software as needed. At this time, the radio base station resets. Furthermore, in the event of a defect in providing communication services, the radio base station resets in some cases in order to clear the situation. When the wireless base station resets, it reduces the cell range (the range of the cell where radio waves of the wireless base station reach) (or lowers the transmission power). In addition,...
