Abstract
A portable radio telephone equipment in which both the frequency and equipment can be used in common to CMTS and MCS so that the efficiency for use both for the frequency and equipment can be improved. This equipment monitors the control channel number of CMTS through a radio transmission section and a control section for common use to CMTS and MCS and answers a call from a base station or performs transmission. On the other hand, this equipment selectively receives the control channel number of MCS and answers a call from a base station or performs transmission. Either one of these actions is automatically selected on the basis of the reception level and system ID of the control channel number. At this time, standby-state reception is performed on the judgment as to which one of CMTS and MCS is to be accessed, by automatically detecting the positional condition of the equipment in use. When the equipment is moved to a different area in CMTS or MCS, either one of CMTS and MCS is automatically accessed after position registration.
