According to one embodiment, a mobile wireless terminal device includes a receiver detecting a beacon and a communication module detecting a base station identification. The receiver comprises an accumulation module accumulating levels of a sampling received wireless signal to obtain a reception profile, a correlation module detecting a shift amount maximizing a correlation between a present reception profile and a past reception profile, a first detector detecting a beacon, when a difference between the detected shift amount and a default amount is larger than a predetermined amount, in accordance with a difference between a shifted profile by the default amount, and the present reception profile, and a second detector which detects a beacon, when the difference is not larger than the predetermined amount, in accordance with a difference between a shifted profile by the detected shift amount, and the present reception profile.
