Abstract

A wireless communications devicecomprising a wireless control function unit, a Bluetooth control function unit, and a user interface unit, wherein the device has, as the Bluetooth, at least one of a (i) Hands-Free Profile, (ii) Dial-up Networking Profile/Personal Area Network Profile, and (iii) Generic Object Exchange Profile. This deviceoptimally implements the Bluetooth low-consumption mode in accordance with the contents of the profiles of the foregoing items (i) to (iii) in view of the system efficiency by (a) invalidating the low-consumption mode or (b) validating the low-consumption mode so as to reduce the number of data transmissions per unit time in the case of (i), make the time parameters of each of the Hold, Sniff, and Park modes variable or alternatively make the manner of implementation of the low-consumption mode variable depending on whether the channel of the data transmission is a dedicated physical channel or a common physical channel in the case of (ii), and shift to the low-consumption mode only in a single-data transfer mode and prohibit it in an all-data transfer mode in the case of (iii).
