Abstract
Abstract The present invention aims at reducing power consumption in a radio communication apparatus having a plurality of radio sections capable of selective switching by controlling power to be supplied to each of the radio sections. To this end, the apparatus includes: a power-supply condition memory section in which conditions for controlling power supply are previously set and stored; and a control section for controlling power supply to the other radio sections based on the value of a reception-signal quality signal from a currently selected radio section and the conditions previously set and stored to the power-supply condition memory section. A reference value for controlling power supply is previously set and stored to the power-supply condition memory section as a power-supply condition. At the control section, the value of a reception-signal quality signal from the currently selected radio section is compared with the reference value previously set and stored to the power-supply condition memory section. Power supply to the other radio sections is stopped when the receiving status of the currently selected radio section is excellent and power supply to the other radio sections is resumed when the receiving status is poor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
116 words
A radio communication apparatus having a plurality of radio sections for selectively switching, said radio communication apparatus comprising: a power-supply condition memory section for previously setting and storing conditions for controlling power supply; a control section for controlling power supply to the other radio sections based on the value of a reception-signal quality signal from a currently selected radio section and the conditions previously set and stored to said power-supply condition memory section; and a talking route selecting condition memory section for previously setting and storing conditions for selecting a talking route, said control section controlling power supply to the radio sections based on the conditions previously stored to said talking route selecting condition memory section.
Claim 2
Dependent Claim
116 words
A radio communication apparatus having a plurality of radio sections for selectively switching, said radio communication apparatus comprising: a power-supply condition memory section for previously setting and storing conditions for controlling power supply; a control section for controlling power supply to the other radio sections based on the value of a reception-signal quality signal from a currently selected radio section and the conditions previously set and stored to said power-supply condition memory section; and a talking route selecting condition memory section for previously setting and storing conditions for selecting a talking route, said control section controlling power supply to the radio sections based on the conditions previously stored to said talking route selecting condition memory section.
Claim 3
Dependent Claim
101 words
The radio communication apparatus according to claim 1, wherein a reference value for controlling power supply is previously set and stored to said power-supply condition memory section; and wherein said control section compares the value of a reception-signal quality signal from the currently selected radio section with the reference value previously set and stored to said power-supply condition memory section, said control section stopping power supply to the other radio sections when the receiving status of the currently selected radio section is better, and said control section resuming power supply to the other radio sections when the receiving status is worse.
Claim 4
Dependent Claim
91 words
The radio communication apparatus according to claim 1, wherein values of power supplying interval for the other radio sections corresponding to the values of the reception-signal quality signal of the currently selected radio section are set and stored to said power-supply condition memory section, said control section obtaining a value of power supplying interval for the other radio sections from said power-supply condition memory section based on the value of a reception-signal quality signal from the currently selected radio section to set the power supplying interval for the other radio sections.
Claim 5
Dependent Claim
72 words
The radio communication apparatus according to claim 1, wherein priority for each radio section is set and stored to said talking route selecting condition memory section; and wherein said control section compares the priority of the currently selected radio section with the priority of the other radio sections and effects control so as to limit power supply to the other sections only when the priority of the other radio sections is lower.
Claim 6
Dependent Claim
79 words
The radio communication apparatus according to claim 1, wherein indispensability or dispensability of power supply control with respect to each radio section is set and stored to said talking route selecting condition memory section; and wherein said control section confirms for each radio section the indispensability for effecting a power supply control stored to said talking route selecting condition memory section and effects control so as to limit power supply to a radio section only when set as indispensable.
