Mobile phone and movable state testing device

Abstract

A portable telephone allowing easy and accurate estimation of its moving speed at the moment when an incoming call is received is disclosed. A moving status detector is provided which detects a moving status of the portable telephone based on measured reception signal strengths, each of which is measured on a sequentially selected one of N neighboring radio channels that are previously designated by the base station at a timing other than a communication timing of the designated radio channel in response to receipt of a call setup signal for an incoming call from the base station using the designated radio channel.

Description

technical field [0001] The present invention relates to a portable phone with a moving state detection function, in particular to a moving state detection technology in which the portable phone itself determines whether it is stationary or moving at high speed during an incoming call receiving operation. Background technique [0002] With the recent widespread use of portable phones, it has now been found that the use of the portable phones causes troubles to neighbors depending on the usage environment. It is also known that using a portable phone while driving may lead to a traffic accident. Therefore, during driving or on a train, it is required that people should observe etiquette rules and ensure safety when using portable phones. [0003] Japanese Patent Application No. 10-224856 discloses an example of a mobile communication terminal complying with such rules. The mobile terminal is provided with a receiving electric field intensity detector and an attenuation slope...
