Abstract
A system and method for managing calls in a mobile communication system transmits information indicative of an operational state of a first mobile terminal to a second mobile terminal for display. The first terminal may be a called terminal and the second terminal a calling terminal. A user of the second terminal can therefore recognize a reason for a communication blockage if a call between the first and second terminals is lost.

6. A method of managing communications in a mobile communication system, comprising:
-
storing, in a base station, state information transmitted from a first mobile terminal;
monitoring a call connection between the first mobile terminal and a second mobile terminal; and
transmitting the stored state information transmitted from the first mobile terminal to the second mobile terminal when the call connection between the first and second mobile terminals is terminated. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method of managing calls in a mobile communication system, comprising:
-
connecting a call between an originating side terminal and a receiving side terminal;
periodically storing state information transmitted from at least one of the originating side and receiving side terminals in a base station;
monitoring a call connection between the originating side and receiving side terminals;
if the originating side and receiving side terminals are in a call connection state, storing status information for each of the terminals;
if the call connection between the terminals is interrupted, checking whether the call has been interrupted because of a network failure;
if the call has been interrupted because of a network failure, automatically attempting a recall from the originating side terminal;
if a call termination message is received from the originating side terminal or from the receiving side terminal, releasing the call connection between the terminals at the base station; and
transmitting the state information of one of the originating side and receiving side terminals to the other of the originating side and receiving side terminals after the call connection release. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method of managing calls in a mobile communication system, comprising:
-
connecting a call between an originating side terminal and a receiving side terminal;
transmitting state information of the originating side terminal to a base station;
checking whether a call termination message is input from a user in response to a call interruption;
sensing whether an RSSI is restored to a level sufficient to make a call available;
if the RSSI is restored, automatically attempting a recall based on a phone number stored in a memory;
when the call to the receiving side terminal is terminated, receiving state information of the receiving side terminal; and
displaying the state information on the originating side terminal. - View Dependent Claims (22, 23, 24, 25)
