Abstract
This invention is directed to a method for increasing the probability of the success of handoff service in a mobile communication system. The present invention provides a handoff method for improving the talk quality in which a probability of the handoff success is raised and a probability of a call outage to disconnect a busy call is reduced. A handoff method of the present invention comprises the steps of a first step of requesting a handoff service repeatedly with a regular interval based on a timer from a mobile station to a service base station until the mobile station received the handoff service if a pilot strength of a neighboring base station is greater than a base station pilot strength value (T-ADD) when the mobile station enters a handoff service region; and a second step of holding back a new call service in the neighboring base station if the mobile station requesting the handoff service does not receive the handoff service and assigning a released channel to the mobile station requesting repeatedly the handoff service released call is present.
