Abstract

There are provided: a main receiving unit for receiving incoming signals from a base station via a main antenna provided in a portable terminal; sub receiving units for receiving incoming signals from the base station via a plurality of detection antennas provided in the portable terminal; a detection unit for detecting the arriving direction of base station signals in the radio wave environment of the portable terminal based on receiving level information of the main antenna, on receiving level information of the detection antennas and on directivity information of the detection antennas; and notifying units for notifying information about the arriving direction of the base station signals detected by the detection unit.

Description

technical field [0001] The present invention relates to a portable terminal and a portable terminal communication method for performing communication while minimizing deterioration of communication quality even when a radio wave environment is in a deadlock. Background technique [0002] There are mobile phones that include multiple antennas in order to have a diversity effect. [0003] A base station transmits radio waves within a service area and forms a call channel between it and a mobile phone by using the radio waves. Radio waves transmitted from base stations have strong directionality, so reception conditions in mobile phones can fluctuate depending on the direction in which radio waves arrive. [0004] On the other hand, when describing a mobile phone, the mobile phone is formed in a slim shape for portability so that a user can easily hold it with one hand. In a mobile phone, a receiver is housed in one end of an elongated phone body, and an antenna is incorporat...
