DIGITAL CORDLESS TELEPHONE SET

摘要

PURPOSE:To obtain the digital cordless telephone set in which a master set is smoothly connected to a mobile slave set when it is able to be communicated with the master set and the slave set is smoothly connected to an outdoor base station when not communicated. CONSTITUTION:A CCH (control channel) control section 9 discriminates whether or not a mobile slave set is resident in a range of communication available of an indoor master set based on a reception signal level of a slot sent from the indoor master set measured by an RF/IF reception section 1 of the slave set. Furthermore, a BCCH storage section 9d stores a superframe structure sent by an outdoor base station, and the CCH control section gives a command of a transmission reception timing and a transmission reception frequency to the RF/IF reception section 1 and an RF/IF transmission section 2 based on information of control data and the result of measured level from the RF/IF reception section and on information with respect to the superframe stored in the BCCH storage section.
