PURPOSE: A call process method through a busy channel of a digital communication terminal is provided to increase a convenience by offering a voice call through a channel which a suspended call occupies when two channels are busy. CONSTITUTION: A network receives a call set message, and confirms whether an in-coming side terminal is registered at a BCS service according to the call set message or not(S42). Next, the network confirms whether two channels assigned to the in-coming side terminal are busy or not(S43). When the two channels are busy, the network confirms whether a voice call flows in or not(S44). When the voice call flows in, the network transmits the call set message to the in-coming side terminal(S45). After this, the in-coming side terminal confirms whether the two channels are busy or not(S46). If the two channels are busy, the in-coming side terminal receives the voice call(S47), and reports a fact of receiving the voice call to a user. After this, when the user presses a BCS key, the in-coming side terminal suspends a present busy call temporarily(S49), and transmits a temporary suspending message to the network(S50). The network suspends the present busy call temporarily, and performs a call process through a channel which the present busy call occupies(S51).
