Patent ID: 7272399

Claim:
A method of recovering a dropped call in a mobile station, comprising the steps of: determining whether two consecutive good frames have been received on a traffic channel that was disconnected to determine if the disconnected traffic channel has been recovered when the dropped call occurs; searching an adjacent base station whose pilot signal arrives at the mobile station with a greater received signal strength using a searcher, at the same time said determining step is performed; requesting a traffic channel to the searched base station so that the traffic channel is assigned to the mobile station, using a physical channel used for data transmission service; determining which one of the following occurs first: (a) receiving two consecutive good frames through the disconnected traffic channel and recovering the disconnected traffic channel, and (b) assigning the traffic channel from the searched base station to the mobile station; and shortening call recovery time by resuming the call on the traffic channel that is first available between the recovered traffic channel and the assigned traffic channel according to the determination result.
