Abstract

PURPOSE:To assign each general processor to each of overlapping calls even if the calls arise as overlapping by providing plural general processors whose programs for protocol conversion can be freely updated, and using them by updating the program for protocol conversion into the program for protocol conversion corresponding to an exchange in response to the request of the exchange. CONSTITUTION:The subject system is provided with plural general processors 2 to 4 whose programs for protocol conversion can be freely updated respectively, a memory 6 in which various kinds of the programs for protocol conversion are stored, a connecting means 7 to connect between respective exchanges 8, 9 and respective general processors 2 to 4, and a control means 5 which selects the general processors 2 to 4 in an idle state in response to the request of the exchanges 8, 9, and controls the connecting means 7 to connect between them, and simultaneously, reads out the program for protocol conversion suitable to the exchanges 8, 9 from the memory 6 and updates the program for protocol conversion of the general processors 2 to 4. Thus, even if the cells arise while overlapping from plural exchanges using the same protocol, conversion processing can be executed in parallel by the necessary number of the general processors 2 to 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a protocol conversion method for converting the protocol of an exchange and connecting it to another exchange using a different protocol.

[Conventional technology]

When connecting exchanges that each use a separate protocol, a dedicated processor is provided for each protocol,
These buttons are operated by a protocol conversion program corresponding to each protocol, thereby mutually converting the protocols of each exchange.

[Problem to be solved by the invention]

However, since each processor is dedicated to each individual protocol, if calls are duplicated from multiple exchanges using the same protocol, calls will be sent to a specific processor even if the processors for other protocols are empty. Calls are concentrated,
This has resulted in the drawback that it is impossible to process this.

[Means to solve all problems]

In order to solve the above-mentioned problems, the present invention is configured by the following means.

In other words, the method KTh that performs all of the above-mentioned protocol conversions includes a plurality of general-purpose processors, each of which can freely update its protocol conversion program, a memory storing various protocol conversion programs, and communication between each exchange and each general-purpose processor. Selects the connection means to be connected and an empty general-purpose processor according to the request of the exchange, controls the connection means and connects them, reads a protocol conversion program suitable for the exchange from memory and runs this program.) The control means for updating the protocol conversion program of the general-purpose processor is provided.

[Effect]

Therefore, even if multiple calls occur from multiple exchanges using the same protocol, in which each general-purpose processor shares various protocols, conversion processing can be performed in parallel using the required number of general-purpose grossexers. Impossibility of conversion processing does not occur.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to figures showing examples.

Figure 1 is a block diagram of the entire configuration, with 1 system bus (hereinafter referred to as bus) and 1 general purpose processor (hereinafter referred to as GUP).
2 to 4, a system control block (hereinafter referred to as 5CB) 5 as a control means is connected, and a disk memory (hereinafter referred to as DSM) 6 is connected to 5CB5, while connections that are frequently controlled by 5CB5 A line switch block (hereinafter referred to as LSB) 7 serving as a means connects GUPs 2 to 4 and exchanges (hereinafter referred to as gx) a to 9.

Additionally, EX13 to EX9 each use a different protocol, and the DSMB stores various protocol conversion programs accordingly.
2 to 4 use a RAM as a memory for each program, so that each protocol conversion program can be updated freely.

2 to 6 show each state in which each part of FIG. 1 operates, and in the initial state of FIG. 2, each EX8 to
None of GUP 9 generates a call, and the RAM of each GUP 2 to 4 is in a clear state.

FIG. 3 shows when EX8 generates the calling signal 10,
When this is given to 8CB5 as a request signal 11 via LSBT, 5CB5 selects GUP2 from empty GtJP2 to GtJP4, controls I and SBr, and connects EX8 and GU
At the same time, read from the protocol conversion program t-DSMB corresponding to EX8 and transfer it to GUP2 via bus 1 using IPL signal 12, thereby converting GUP2 by this program. The state is set for processing.

Then, GUP2 sends a communication start signal 13 to 5CB5 via bus 1, so 5CB5 responds to this by
Recognizes the start of P2 operation.

Figure 4 shows when GUP2 performs reception processing and connects to EX9 in response to this, and GUP2 performs reception processing and connects to EX9.
When the conversion request signal 14 to be sent to QUP9 is sent to 5CB5, 5CB5 responds to the empty state of QUP3~
Select GUP3 from 4 and use the protocol conversion program compatible with EX9? Read from DSM6, this IIP
Transferred to GUP3 by L signal 15, G via bus 1
The output of UP2 is converted to the protocol of t-EX9, and a notification signal 16f is sent to the LSBT, and this is controlled to connect GUP3 and EX9.

FIG. 5 shows the case where EXfJ generates another call.
In response to the calling signal 17 from 8, GUP 2 gives a congestion signal 18 to 5CB 5 to notify of call congestion.
Select GUP4 with 5CB5 empty, and install the protocol conversion program corresponding to EXB to DSM as shown in Figure 3.
read from S and send it to GUP4 by IPL signal 19.
After transferring the notification signal 20 to LaB5, it controls this and connects EX8 and GUP4.

Therefore, even if multiple calls using the same protocol occur, the conversion process is performed in parallel in multiple GUP2.4s, and calls will not be unable to be processed.

Even if other protocol change protocols are already stored in the RAMs of GUPs 2 to 4, the contents of the fiRAM are updated by the desired protocol change program, so the corresponding conversion process is performed.

Figure 6 shows that when the signal exchange between EX13 and EX9 is completed, GUP2 sends a communication end signal 22 to 5CB5 in response to the disconnection signal 21 from gxB, so this ends the first communication. 5CB5 recognized this and GUP
2.3 is stored as an empty state.

However, even if the communication ends, the LaB5 contact
In addition, it is prepared in case a call from EX8 occurs.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the protocol conversion program j! Provide multiple general-purpose processors at will, and empty general-purpose processors according to the demands of the exchange? By selecting this program and updating the program to a protocol conversion program compatible with the exchange, even if calls using the same protocol occur repeatedly, each general-purpose processor can be assigned to these calls at will. However, there is no inability to process calls, and a remarkable effect can be obtained in protocol conversion between exchanges.
