Problems solved by technology

Thus, a mobile station located at the edge of its cell and consuming a large amount of transmit power can overload the power supply and reduce the capacity of the base station
This results in a decrease in overall system communication efficiency
[0026] The purpose of the present invention is to prevent the reduction of the communication efficiency of the whole mobile communication system based on DHO

Embodiment Construction

[0045] Embodiments of the mobile communication system according to the present invention will be described in detail below with reference to the drawings.

[0046] Figure 1~6 A mobile communication system 1 to which the present invention is applied is shown. The mobile communication system 1 uses a diversity handover (DHO) scheme.

[0047] First, the structure of this system will be described.

[0048] figure 1 The system structure of the mobile communication system 1 according to the present invention is shown. figure 1 The mobile communication system in the mobile communication system includes a backbone network 10, radio communication control devices 20, 30, base stations 21-23 and 31 and 32, and mobile stations 41-43.

[0049] Backbone network 10 is a typical cellular telephone network and includes switches and the like. The radio communication control devices 20 and 30 communicate with each other through the backbone network 10 .

[0050] The radio communication ...

Abstract

A mobile communication system 1 to which the present invention is applied changes appropriately the information rate at which communication between a mobile station and a base station is performed, according to the number of DHO branches of the mobile station. Thus, overload on power resources at the base station can be prevented and decreases in capacity of the base station and decreases in communication efficiency of the entire mobile communication system 1 can be prevented. The number of DHO branches is managed by radio communication control apparatuses 20, 30 and therefore the effects of the present invention can be obtained with little modification to the hardware resources of an existing mobile communication system.

Description

technical field [0001] The present invention relates to a mobile communication system including many base stations and mobile communication devices, and a radio communication control device, mobile communication device and mobile communication method. Background technique [0002] In recent years, the spread of cellular telephones and the like has significantly increased the use of mobile communication systems. [0003] In current mobile communication systems, many base stations having predetermined coverage areas (hereinafter referred to as "cells") are installed at many locations. A mobile station (mobile communication device) can use the system when it is located in at least one base station cell. That is, the cells of the base station together constitute the service range of the system. [0004] In this mobile communication system, the information rate between the base station and the mobile station depends on the communication quality, which is closely related to the ...
