ABSTRACT:
Disclosed is a method for establishing a call connection in a wireless terminal, which can make a call connection using one line number when a call connection fails through another line number in a wireless terminal subscribing to a service in which the portable terminal uses two line numbers. The method includes receiving call release signals from a mobile switching center with respect to a call request of the wireless terminal; reattempting the call request in the wireless terminal with respect to the mobile switching center using a line number having priority, when the call release signal is received from the mobile switching center to the wireless terminal; and assigning resources from a resource pool used for another purpose so as to establish the call connection to the line number having priority when the mobile switching center receives the call request, which uses the line number having the priority, from the wireless terminal again.
