METHOD OF CONNECTING A CORDLESS TELEPHONE BY RADIO

摘要

A method of connecting a cordless telephone by radio without using control channels selects priority radio channels from radio channels which are shared by cordless telephones and assigns each of them to a respective one of the cordless telephones. So long as the priority radio channel assigned to any of the telephones is not occupied by another telephone, that telephone uses it. A portable unit of the telephone is allowed to enter into a call origination flow in response to a call origination request only after confirming that an incoming calling signal is not being sent over the priority radio channel from a fixed unit which is associated with the portable unit. Even when a call origination request occurs before a radio connection for an incoming call, the fixed and portable units are prevented from tuning to different radio channels without the need for a control channel.
