Mobile station and standby method

Abstract

A mobile station (UE) comprises a management unit (12) that associates a macro-cell with a home cell the access right of which has been established for the mobile station; and a standby processing unit (14) that, when broadcast information is received from the macro-cell, determines, based on the result of a comparison between the radio quality in the home cell with which the macro-cell has been associated and the radio quality in a standby cell, whether to start a standby in the home cell.

Description

technical field [0001] The present invention relates to a mobile station and a standby method. Background technique [0002] Such as figure 1 As shown, there is known a mobile communication system in which macro cells #A to #G belonging to the same location registration area LA#α are installed, and in the macro cell #A, an access right is set for the mobile station UE. Family Quarter #a. Here, frequency #f1 is used in the macro cells #A to #G, and frequency #f2 is used in the home cell #a. [0003] In this mobile communication system, the mobile station UE needs to perform location registration processing for the home cell #a in order to wait in the home cell #a. [0004] Also, in order to change the standby cell, the mobile station UE needs to compare the radio quality in the current cell with the radio quality in the neighboring cells based on the information indicating the neighboring cells included in the notification information. [0005] Usually, the mobile station...

Problems solved by technology

[0006] However, when the mobile station UE changes the standby cell within the same location registration area, or when the cycle timer is being activated, the location registration process may not be performed temporarily in order to prevent the mobile station UE from consuming excess power (additional Connection processing), there is a problem that even if the mobile station UE comes near the home cell #a, it still stays in the standby state in the macro cell #A, and the start of standby in the home cell #a may be delayed

[0007] In addition, the mobile station UE can detect the home cell #a by notifying the information indicating the neighboring cells of each macro cell by using the notification information. The problem that the time spent on the cell search process of the station UE increases

[0008] In addition, for a mobile station UE that does not have the right to access the home cell #a, there is also the problem of searching for the home cell #a

[0009] In addition, in the location registration process, the mobile station UE can be instructed to measure the radio quality in the home cell for which the access right is set for the mobile station UE. However, the mobile station UE cannot Since the radio quality is measured in the home cell #a, there is a problem that the power consumption of the mobile station UE may increase due to redundant inter-frequency measurement processing
