Abstract

PURPOSE:To attain multiple address information near at the same time with a time difference through a multiple address instruction from a processor by providing a multiple address controller connected to a terminal equipment group via a data link. CONSTITUTION:The multiple address controller 4 receives a synchronizing control instruction from a main processor (MP) 2 via a communication bus 5 and the received instruction is informed to plural terminal controllers 7 via the data link 6 in terms of multiple address. The data link 6 accommodates plural terminal controllers 7 and the multiple address controller 4 to apply eachange connection by the control of the MP 2. The terminal controller 7 is connected at each terminal equipment 8 to control the terminal equipment 8 according to the instruction of a local processor (LP) 1. In the inter-MP exchange processing task, the multiple address control processing is not executed between the MP and Lp processing but executed by the instruction from the MP 2 to the multiple address controller 4. Thus, the multiple address control to the plural terminal controllers 7 is executed by one processing.

Description

[Detailed Description of the Invention] Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a broadcast control method for an electronic exchange, and in particular, a method for simultaneously broadcasting to a group of terminal devices accommodated in a multiprocessor type electronic exchange. This invention relates to a broadcast control system for electronic exchanges.

[Conventional technology]

The conventional broadcast control system for electronic exchanges uses software to perform pseudo-control over a group of terminals that are divided and controlled by distributed processors. In software-based pseudo control, all load-balanced processors receive control orders one after another for the same task, and simultaneous control is performed through batch processing, but there is a time difference corresponding to the processing time difference from the start to the end of control. A distributed control multiprocessor type electronic exchange has a local processor (hereinafter referred to as LP) and a main processor (hereinafter referred to as f&MP),
The LP performs terminal control processing, and the MP performs exchange processing. L
Terminal control processing within P is normally performed in accordance with control instructions from the MP side as a result of MP exchange processing. For example, when performing broadcast control for multiple terminals in normal processing, M
The exchange processing task of P sequentially sends control instructions to a plurality of LPs whose control is subordinate to the terminal control device. In such processing, when the number of commanded LPs is large, a processing time difference occurs between the LPs, and complete broadcast control for a group of terminals is not achieved. Therefore, the conventional broadcast control method cannot be adopted in the case of a terminal device that has large operational time constraints, such as simultaneous display of incoming calls on a central office relay stand.

[Problem that the invention seeks to solve]

The above-mentioned broadcast control method of the conventional electronic switching system is configured such that the switching processing task of the main processor sequentially sends control instruction commands to a plurality of local processors that control terminal devices. When the number of terminals is large, there is a problem that a processing time difference occurs between LPs, making it impossible to control all terminal devices simultaneously and making broadcast control impossible.

An object of the present invention is to provide a broadcast control system for an electronic exchange that solves the problem described in item 1 above.

[Means for solving problems]

The broadcast control method of the present invention is a broadcast control method for an electronic exchange that simultaneously sends notifications to a group of terminal devices housed in a multiprocessor type electronic exchange. a distributed processor that commands the control of the processor and executes exchange processing; a broadcast control device that simultaneously transmits broadcast control commands received directly from the processor to the connected terminal control devices; and a plurality of the terminals. and a data link that accommodates and connects a control device and at least one of the broadcast control devices, and exchanges and processes mutual connections between the terminal control device and the broadcast control device under the control of the processor.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In FIG. 1, a local processor LPI, a main processor MP2, a central bus 3, a broadcast control device 4, a communication bus 5, a data link 6, a terminal control device 7, and a terminal device 8 are shown. LPl is a processor that controls changes in the status of the terminal via the terminal control device, and performs input/output processing for exchange processing. The MP2 is connected to the LPI via the central bus 3, and executes exchange processing tasks according to exchange processing instructions from the LP1 (N+1> configuration).The broadcast control device 4 executes exchange processing tasks according to exchange processing instructions from the LPI (N+1> configuration). is received via the communication bus 5, and the received command is further broadcasted to a plurality of terminal control devices 7 via the data link 6.

The data link 6 accommodates a plurality of terminal control devices 7 and a broadcast control device W4, and is exchange-connected under the control of the MP2. The terminal control device 7 is connected to each terminal device 8 and controls the terminal device 8 according to LPI instructions.

In the intra-MP exchange processing task, the broadcast control processing is performed by MP-LP.
It is not executed as an intermittent process, but is executed by a command from the MP 2 to the broadcast control device 4. Therefore, broadcast control for a plurality of terminal control devices 7 can be executed in one process.

〔Effect of the invention〕

As explained above, the present invention provides a broadcast control device that connects via a data link to a group of terminal devices that are distributed and controlled by a plurality of processors in a multiprocessor type electronic exchange in conjunction with an exchange processing program. , there is a service effect in which the broadcast control device can send simultaneous broadcasts almost simultaneously without any time lag in response to broadcast commands from the processor.
