Mobile wireless terminal device

Abstract

A non-contact IC control unit 203 reads information, which is acquired and stored by a non-contact IC 202 via short-distance communication with a reader / writer 206, each time an interrupt is received from a timer unit 207 and, if data that is read includes new function limiting information on a mobile phone, outputs an interrupt signal and the function limiting information to a CPU 201, and the CPU 201 places function limitations on the miscellaneous-module peripheral unit 205 according to the received function limiting information. If the function limiting information indicates that the power of the mobile phone should be turned off, the CPU 201 turns off the power supplied to the miscellaneous-module peripheral unit 205 and, at the same time, changes over the CPU 201 itself to a dormant state except the function that accepts an interrupt signal.

Description

technical field [0001] The present invention relates to a technology for restricting the functions of portable wireless terminals such as mobile phones in a predetermined area, and in particular to a function restriction and release of a portable wireless terminal equipped with a non-contact IC when entering and exiting a predetermined area. Technology. Background technique [0002] In transportation facilities such as railways, there are many cases where calls are made to control in-vehicle calls. Therefore, it is necessary to set a mobile phone to a polite mode or turn off the power in the car. However, most users find the operation troublesome and do not perform setting changes. Therefore, various methods have been proposed for automatically setting restrictions on a mobile phone that enters an area where the use of the mobile phone is restricted. [0003] For example, in Patent Document 1, a method of using Bluetooth (registered trademark) is proposed as a means of aut...

Problems solved by technology

[0016] However, when the power supply of the mobile phone is turned off to stop the functions of the mobile phone, and the CPU that performs the function control of all the various modules included in the mobile phone is always supplied with operating power, the consumption of From the point of view of current, it becomes wasteful power consumption, and there is a problem that a mobile phone using a storage battery as a power source shortens the time it can be used with one charge.
