Abstract

PURPOSE:To shorten processing time by registering switch connecting patterns based on a switch connecting pattern register request from a call control task means in the switch connecting means, selecting the corresponding switch connecting pattern in a switch control means, and controlling a hardware control part. CONSTITUTION:A switch connecting pattern management means 30 is started by the switch connecting pattern register request from a call control task means 10, and registers the switch connecting pattern. A switch control means 20 reads out the connecting pattern managed by the means 30 based on the switch connecting request from the means 10, and instructs the switch connection to a hardware control part 40 of a main switch so as to realize the corresponding switch connection. The control part 40 of the main switch executes the switch connection instructed by the means 20. Thus, a transient cutting sequence at transferring time can be omitted and the processing time accompanied by the sequence can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applied to a switch control device for an exchange. In particular, the present invention relates to a switch control device controlled by software of an exchange.

〔overview〕

The present invention provides a switch control device in which a plurality of switch connection patterns are registered and one of the plurality of patterns is selected and instructed to a hardware control unit in response to a switch connection request. In this embodiment, it is possible to omit a transient disconnection sequence at the time of transfer and shorten the associated processing time.

[Conventional technology]

Conventionally, a switch control device of an exchange has been supposed to instruct a hardware control section of a main switch to perform switch control and change the state of the switch based on a switch connection request from a call control task means.

Further, the switch control means 20 reads out the switch connection pattern registered in the switch connection pattern management means 30 based on the switch disconnection request from the call control task means 10, and controls the corresponding transmission/reception disconnection process using the hardware control unit. 40.

The operation of the switch control device having such a configuration will be explained. FIG. 2 is a diagram showing a switch connection pattern of a switch control device according to an embodiment of the present invention.

FIG. 3 is a diagram showing a switch connection pattern during call transfer processing by the switch control device of the present invention.

In FIG. 1, the switch connection pattern management means 30 is
It is activated by a switch connection pattern registration request from the call control task means 10, and registers the switch connection pattern.

Based on the switch connection request from the call control task means 10, the switch control means 20 reads the connection pattern managed by the switch connection pattern management means 30, and controls the hardware control section of the main switch so as to make the corresponding switch connection. 40 to connect the switch.

The hardware control unit 40 of the main switch executes switch connections instructed by the switch control means 20.

FIG. 2 is a diagram related to the switch connection pattern between terminals A and B, and shows the empty state 100 [FIG. 2 (a), the L transmission connection state 110 [FIG. 2 (b)], and the reception connection state 120 [FIG. 2 (b)] for terminal A, respectively. Figure 2 (C)] and transmission/reception connection status 13

FIG. 3 is a diagram showing an example of a case where multiple switch connection patterns exist for one terminal during call transfer, etc.
This shows a case in which a pattern representing a transmission/reception connection state 200 between terminal A and terminal B and a pattern representing transmission/reception connection state 210 with terminal C exist simultaneously.

The operation when connecting and disconnecting transmission/reception between terminals A and B will be described.

First, the call control task means 10 informs the switch connection pattern management means 30 of the transmission/reception connection status between terminals A and B.
Register 0.

Next, the call control task means 10 executes the switch control means 20.
Terminals A and B are requested to be connected to the switch.

In response to this, the switch control means 20 transmits the transmission/reception connection status 1 between the terminals A and B from the switch connection pattern management means 30.
30 patterns are read out, and a request is made to the node\-ware control unit 40 for switch control corresponding to the read connection pattern, that is, transmission/reception connection processing between terminals A and B.

The hardware control section 40 performs hardware control according to a request from the switch control means 20, and ends the connection operation.

When disconnecting transmission and reception between terminals A and B, the call control task means 10 requests the switch control section 20 to disconnect the switch. In response to this, the switch control means 20 reads the connection state between the terminals A and B from the switch connection pattern management means 30, and performs switch control corresponding to the read switch connection pattern to the node/ware control section 40, i.e. Requests transmission/reception disconnection processing between terminals A and B. The hardware control unit 40 performs hardware control in accordance with a request from the switch control means 20, and disconnects the main switch.

After this, the call control task means 10 requests the switch connection pattern management means 30 to delete the switch connection pattern between terminals A and B. The switch connection pattern management means 30 deletes the corresponding connection pattern and ends the disconnection operation.

The relationship between the switch connection pattern and the switch control means 20 will be explained in detail with reference to FIGS. 1 and 2.

When the call control task means 10 requests the switch control means 20 to connect to the terminal A, the process that the switch control means 20 requests to the hardware control section 40 is registered in the switch connection pattern management means 30. Determined by connection pattern. If the connection pattern related to terminal A registered in the switch connection pattern management means 30 is the transmission connection state 110 with terminal B, then the transmission connection processing is performed, and if the reception connection state with terminal B is 120, the reception connection processing is performed. If the transmission/reception connection status with B is 130, a request is made to the hardware control unit 40 for transmission/reception connection processing.

As described above, in this embodiment, it is possible to shorten the processing sequence in call transfer processing and three-party communication, and to concomitantly shorten the processing time.

The operation when a call is transferred to a call between terminals A and C during a call between terminals A and B will be described below.

During a call between terminals ASB, the transmission/reception connection state 20 (between terminals A and B) is registered in the switch connection pattern management means 30.

The call control task means 10 first communicates between the terminal A and the transfer destination terminal C.
The transmission/reception connection status 210 between terminals A and C, which is the switch connection pattern with the terminals A and C, is registered in the switch connection pattern management means 30. At this time, in order to distinguish between the two connection patterns for terminal A, terminal A will be expressed as terminal AA (see Figure 3).

Next, the call control task means 10 requests the switch control means 20 to connect the terminal AA.

The switch control means 20 reads the switch connection pattern regarding the terminal AA from the switch connection pattern management means 30. At this time, since terminal AA and terminal A are the same terminal, a request is made to the hardware control unit 40 for a transmission/reception connection between terminal A and terminal C.

The hardware control unit 40 transmits and receives the transmission and reception connection status g2o between the terminals A and B to the hardware of the main switch.

A request is made to switch to the transmission/reception connection state 210 between terminals A and C.

With the above operation, the switch connection between terminals A and C in the next state can be established without going through the switch disconnection process between terminals A and B to cancel the connection state before call transfer, which was conventionally necessary in call transfer. state.

Also, when ending a call between terminals A and C and returning to a call between terminals ASB, the status can be easily changed by reading out and reusing the registered sending/receiving connection status 200 pattern from the switch connection pattern management means 30. can be transitioned.

〔Effect of the invention〕

As described above, the present invention has the excellent effect of omitting a transient disconnection sequence at the time of call transfer and shortening the associated processing time.
