The invention provides an automatic switching technology of trans-base-station conversation of an MPT1327 analog-cluster communication terminal. The terminal is locked to a system; the base station number of a locking system is firstly searched; when a field signal is weaker than a set threshold value, background scan is started, and the scan is carried out according to the input sequence of four base stations with overlapped coverage into a switching table; when a conversation is over and the status is off-line, a control signal channel just switched to the base stations with overlapped coverage is checked, and re-registration is carried out if a registration condition is met. If the control signal channel is succeed in registration, the scan is conducted according to the scan method set by the terminal until a signal channel meeting the condition is found, and re-registration is carried out. By improving the prior art, the automatic switching technology causes the terminal to automatically choose a base station with a stronger signal when in mobile conversation within an overlapped region of the stations; free switch is also available after getting on line within an overlapped region of a plurality of base stations; conversation on a base station with the strongest field signal is always available so as to ensure the quality of speech and no occurrence of loosing lock once the signal becomes weaker.
