Fig. 3 is the flow chart that busy tone is provided under the dialing tone semi-fixing continuing.
Embodiment
In the present invention, transform when old switch, it is connected relaying by intermodule be linked into media gateway, make it become a module of media gateway.By the semi-fixing continuing mode, provide stationary tone then.
Described semi-fixing continuing mode is meant in the program controlled system, provides transparent path between two links of semi-fixing continuing, promptly is or not physically to fix deadly between two links, but connects by the program control between.Can improve the flexible and accuracy of connection like this.
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, connect relaying by intermodule between media gateway and the switch and be connected, the busy tone that dialing tone that the exchanger user off-hook need be heard and the other side of side's on-hook need hear is provided by the sound resource of media gateway.Busy tone and dialing tone connect relaying by intermodule again by the switching network of media gateway, and the switching network by switch arrives the user at last.
The concrete data configuration and the step of the embodiment of the invention are as follows:
Step 1 provides the stationary tone resource sound resource board on the media gateway, and as dialing tone or busy tone resource, semi-fixing continuing is called time slot A with this time slot to certain time slot of the switching network of media gateway;
Step 2 on certain time slot with the switching network of a media gateway to the circuit semi-fixing continuing between switch module to media gateway, is called time slot B with this time slot;
Step 3 is got up time slot A and time slot B semi-fixing continuing;
Step 4 on switch, on above-mentioned media gateway certain time slot on to the circuit semi-fixing continuing between switch module to the switching network of switch, is called time slot C with this time slot;
By above setting, for exchanger user, the time slot C on the switch is exactly this stationary tone time slot;
Step 5, when the user called, by the medium gateway to report soft switch, soft switch notice media gateway was play this stationary tone to the user, and media gateway continues user's time slot and time slot C, thus the realization subscriber phone is play corresponding stationary tone.
Wherein, described stationary tone comprises dialing tone, busy tone and ring-back tone, number unobtainable tone, Acknowledgement Tone, howler tone etc.Because dialing tone, busy tone are the stationary tones of normal use,, provide dialing tone, busy tone so the present invention mainly is by the semi-fixing continuing mode.That is to say, these two kinds of stationary tones, corresponding two semifixed time slots are the semifixed of busy tone as time slot a---b---c, time slot d----e----f is the semifixed of dialing tone, so the time slot of c and f corresponding busy tone of difference and dialing tone.Other stationary tone, as ring-back tone, number unobtainable tone, Acknowledgement Tone, howler tone etc. also can make in this way, but semifixed too many words, might be because intermodule connects relay resource to be taken too much by semifixed connection, it is not high to cause intermodule to connect the relay resource utilance.

Step 202, media gateway reports soft switch with user's off-hook;
Step 203, soft switch notice media gateway is put dialing tone to the user;
Step 204, media gateway continues user's time slot and time slot C (the dialing tone time slot that semi-fixing continuing is good), and user C has just realized hearing dialing tone.
Like this, just connect time slot, and then user's time slot on the switch has been connected in series between the dialing tone time slot to the gateway piecemeal without the choice of dynamical intermodule.
As shown in Figure 3, with the example that is provided as of busy tone, as above-mentioned step, time slot C just provides the time slot of busy tone, and the using method under the semifixed situation of busy tone is described:
Step 301 is after the calling and called conversation, if called subscriber's on-hook through switch, connects relaying by intermodule and is reported to media gateway;
Step 302, media gateway reports soft switch with called subscriber's on-hook;
Step 303, soft switch notice media gateway is put busy tone to the calling subscriber;
Step 304, media gateway continues calling subscriber's time slot and time slot C (the busy tone time slot that semi-fixing continuing is good), and the calling subscriber has just realized hearing busy tone.
Like this, just connect time slot, and then user's time slot on the switch has been connected in series between the busy tone time slot to the gateway piecemeal without the choice of dynamical intermodule.
In this example, after the calling and called conversation, if calling subscriber's on-hook, situation is also similar, and the called subscriber can hear busy tone, repeats no more herein.
