In step S120, confirm whether to set and export single-tone sign (TONE FLAG) signal by control part 110, if when confirming that setting and output have single-tone sign (TONE FLAG) signal, control audio mark part 140 is set and output audio sign (AUDIO FLAG) signal (seeing step S130), and judges whether the timing operation finishes (seeing step S140).
When the result who judges in step S140 is the timing EO, judged whether to import the order of standby (WAITING CALL) state in the control conversation, that is, judged whether to import the control command (seeing step S150) of exchange (SWAP) control command or recovery and releasing (RETRIEVE AND RELEASE).
Suppose the user for A, call out to connect and the 1st the other side of communication be C for B, as the 2nd the other side of another the other side, the state transformation to Opportunity awaiting control for linear order correspondence in conversing carries out simple explanation below.This example can be divided into the state of a control of following 4 classes.
When state 1:A communicates by letter with B, receive the call connection request of C,
A-B: present (ACTIVE) state A-C: call connection request state
State 2:A allows the call connection request of C,
A-B: keep (HOLD) state A-C: present (ACTIVE) state
State 3: input has exchange (SWAP) control command,
A-B: present (ACTIVE) state A-C: keep (HOLD) state
State 4: input has recovery and removes (RETRIEVE AND RELEASE) control command,
A-B: present (ACTIVE) state A-C: call release state
In state 1, when mobile communication terminal A when receiving the call connection request of mobile communication terminal C during mobile communication terminal B communicates by letter, the set ringtone that will sound and preset.
In the state 2, when mobile communication terminal A with obtain understanding during B converses and call out when being connected with C, the calling of setting between A and the B is maintenance (HOLD) state with change setting, calling between A and the C then change setting is present (ACTIVE) state, and state 2 is states that mobile communication terminal A communicates by letter with mobile communication terminal C.
In the state 3, input has exchange (SWAP) control command under the situation of state 2, promptly, calling between A and the B (CALL) is present (ACTIVE) state from keeping (HOLD) status exchange (SWAP), and the calling between A and the C then is maintenance (HOLD) state from present (ACTIVE) status exchange (SWAP).
Exchange control command in the state 3 can be imported most times, and when each input exchanges (SWAP) control command, the state of original calling and setting all will carry out change setting.
In the state 4, recover and releasing (RETRIEVE AND RELEASE) control command in 2 times inputs of state, that is, in state 2, remove in the calling of (RELEASE) present (ACTIVE) state, will keep the calling change setting of (HOLD) state to be (ACTIVE) state and communication at present.
Standby mark processing method in the conversation of mobile communication terminal is described once more below with reference to above this example.When the control command of exchange (SWAP) or recovery and releasing (RETRIEVE AND RELEASE) is arranged by multimedia department's 130 inputs (seeing step S150), control part 110 confirms whether setting audio identifies (AUDIO FLAG) (seeing step S160).When if the judged result of step S160 is setting audio sign (AUDIO FLAG), the calling change setting that will be set at maintenance (HOLDING) state is the calling of (ACTIVE) state at present, and be in the call communication (seeing step S170) of (ACTIVE) state at present.
Promptly, even if mobile communication terminal receives network obstacles (NETWORK PROBLEM) signal that prompting mobile switching centre (MSC) moment mistake (TEMPORARY FAILURE) causes by the base station, continue to keep original audio path by setting audio sign (AUDIO FLAG), and when input is used for the order of control conversation standby (WAITING CALL) state, will keep the calling change setting of (HOLDING) state to be the calling and the communication of (ACTIVE) state at present.
Therefore, even if network obstacles (NETWORK PROBLEM) takes place, the calling of (ACTIVE) state at present is disengaged, and also can will keep the calling of (HOLDING) state to change to the calling and the communication of (ACTIVE) state at present by control command.
In the standby signal processing procedure of mobile communication terminal, when being moved switching center's moment mistake, set the sign that keeps audio path according to above-described content the present invention, can continue call communication with hold mode.
And even if the network obstacles of mobile switching centre causes taking place the moment mistake, the calling of hold mode can continue by audio path communication, thereby improves the reliability of mobile communication system.
Above embodiment only is used to implementation process of the present invention is described, is not to be used to limit scope of the present invention.
