[Industrial application field]

The present invention relates to a multiple communication procedure control method in a processing device such as a terminal device that controls two communication procedures based on a state transition matrix that has information that determines the process to be executed depending on the current state and the event that has occurred. .

Recently, intelligent terminal devices and the like have come into widespread use, and due to the diversification of communication functions, it has become necessary for one terminal device to support three different communication procedures.

When developing a program to control communication procedures, the process to be executed and the state to transition to next are determined based on the state transition matrix, depending on the current state and the events that have occurred.

If multiple communication procedures are to be supported, resources and the like will be required to implement this, so efficient resource utilization techniques will be required.

[Conventional technology]

FIG. 5 shows an example of the prior art.

In FIG. 5, 50A and 50B are state control tables;
51A and 51B represent state transition matrices provided individually for each communication procedure.

When performing one communication process in a computer system.

It is necessary to perform one communication according to a communication procedure (protocol) that has been predetermined with the communication partner. Although there are many different communication procedures, there are also many similar procedures. There are many programs that control these communication procedures, and conventionally, most of them have been developed as separate programs for each communication procedure.

The program that controls the communication procedure is usually 1, as shown in Figure 5 (a).
, a state transition matrix 51A as shown in (b),
51B is used to realize control.

The state transition matrices 51A and 51B have information that determines the process to be executed and the state to which to transition when a certain event occurs for each current state.

In the prior art, these state transition matrices 51A
It was common practice to prepare a plurality of 51Bs for each communication procedure and perform processing according to each procedure.

[Problem to be solved by the invention]

In the prior art, there are generally many similar communication procedures and many programs that control these communication procedures, but because they are developed separately, the number of similar programs increases, leading to the following problems: is occurring.

(a) When supporting multiple communication procedures, a large amount of resources are required to store the state transition matrix and one communication control program.

(b) There are many similar communication control programs, and their management becomes complicated.

(C) When supporting a new communication procedure, development is required for each of the two, which increases development man-hours.

In particular, these problems are becoming more prominent in highly functional intelligent terminal devices and the like, as the number of communication procedures to be handled increases.

The present invention aims to solve the above-mentioned problems, and aims to reduce the number of programs for efficient resource use when supporting a plurality of communication procedures, and to reduce the number of man-hours when developing new communication procedures.

[Means to solve the problem]

FIG. 1 shows an example of the configuration of the present invention.

In FIG. 1, 10 is a processing device including a CPU and memory, 11 is an application processing unit that performs data communication and processes data, 12 is a communication control unit that controls communication according to various communication procedures, and 13 is a state transition matrix. a state transition control unit that controls state transition in communication based on
4 is a common processing routine consisting of a group of routines that perform processing common to communication procedures; 15 is an individual processing routine consisting of a group of routines that individually perform processing for each communication procedure; and 16 is a common processing routine that includes information on the current state and the matrix to be used. A state control table to be managed, 17 a matrix storage section for storing a state transition matrix, 18 a common matrix common to each communication procedure, and 19A to 19C individual matrices prepared for each communication procedure.

In the present invention, when a certain event occurs with respect to the current communication state, there are two things that must be generally processed.
Focusing on the fact that the next state (sequence) to transition to is often the same for each communication procedure, we extracted the common parts of each communication procedure.

We are trying to unify it.

The common matrix 18 stored in the matrix storage unit 17 has information obtained by extracting parts common to a plurality of communication procedures in the state transition matrix. Moreover, 1 individual matrices 19A to 19C are.

Each communication procedure has information about parts that are not common to a plurality of communication procedures in each state transition matrix.

The state control table 16 is used to store the current state and management information of the common matrix 18 and individual matrices 19A to 19B.

The state transition control unit 13 is activated when an event related to one communication control occurs, and searches for a corresponding element in the common matrix 18 based on the current state and the event that has occurred. If it is valid, the corresponding common processing routine 14 is called based on the information stored in that element. Furthermore, if the corresponding element in the common matrix 18 is not valid, one of the individual matrices 19A to 19C for the currently controlled communication procedure is selected.

A corresponding element is searched among them, and the individual processing routine 15 indicated by the element is called.

[Effect]

Programs that control communication procedures usually operate according to state transition matrices, but similar matrices of programs that control communication procedures do.

Naturally, there will be many things in common.

− Therefore, when supporting multiple similar communication procedures,
These matrices are divided into a common part and individual parts that differ for each procedure, and are controlled by a unified procedure by the state transition control unit 13.

This makes it possible to improve the efficiency of resources, reduce the number of programs, and improve the efficiency of development.

〔Example〕

FIG. 2 is an example of a state transition matrix according to an embodiment of the present invention, FIG. 3 is an example of the configuration of a program used in an embodiment of the present invention, and FIG. 4 is a state transition control according to an embodiment of the present invention. The processing flow of the section is shown below.

In the present invention, in order to control a plurality of communication procedures, the state transition matrix is divided into a common part and an individual part.For example, as shown in FIG. 2, the state transition matrix is divided into one common matrix 18.

It is composed of n individual matrices 19.

Note that the number of nine communication procedures is assumed to be n.

In order to manage these, the state control table 16 stores information such as the common matrix number (No.), the individual matrix number, the current matrix number, and the events that have occurred in the current state 1.

The common matrix number in the state control table 16 is address information for the common matrix 18.

The individual matrix number is address information for the individual matrix 19 depending on the communication procedure used. The current matrix number indicates address information of the matrix currently undergoing transition.

The current state in the state control table 16 is:

Indicates the current state number in the matrix. The event that occurred indicates the event number in the matrix.

The common matrix 18 stores the address of a processing routine to be executed or its identification information at a position determined by a combination of a state number and an event number. Also, if necessary, the state number to which the transition should be made is stored. It is also possible to omit the state number to which the system should transition and include it in the processing routine.

In the common matrix 18, information indicating that two individual parts should be searched is stored if the part determined by the set of state number and event number is not common to each communication procedure.

Information on processing routines that are not common to each communication procedure is managed in the individual matrix 19 corresponding to the communication procedure. Furthermore, among the seven individual tricks 19 shown in Fig. 2,
For elements indicated with "-", common matrix 18
side is the valid part, but to save space 2
By applying well-known techniques, it is also possible to store information in a compressed form if necessary.

The configuration of the program of the state transition control unit 13 shown in FIG. 1 is as shown in FIG. 3, for example.

The program of the state transition control unit 13 is a MAI that accepts events and calls common or individual matrix control.
N matrix control, common matrix control that calls the corresponding common processing routine 14 according to the common matrix 18, and individual matrix that calls individual processing routines 15A to 15X that perform processing specific to the communication procedure, respectively, in accordance with each communication procedure. Consists of programs such as control.

A rough flow of processing by the state transition control unit 13 is shown in FIG. 4, for example.

After accepting the event, examine the current sequence (state). The common matrix 18 is then examined and, if valid, the common processing routine 14 is called. After that processing, change the sequence.

If the common matrix 18 is not valid and the individual matrix of procedure A is valid, the individual processing routine 15A for those six procedures is called and after processing, the sequence is changed. The same applies to processing control using individual matrices regarding other communication procedures.

Specifically, the state transition control unit 13 performs secondary processing such as (1) to (2).

- When starting to use the line, set the common matrix number and the individual matrix number of the communication procedure to be used in the status control table 16 according to the specifications.

■ If the current matrix number in the state control table 16 points to the common matrix 18, depending on the current state and the event that has occurred.

Processing according to the common matrix 18 is performed to set the current state. At this time, if the 7 matrix changes, the matrix number set in step (3) is set to the current matrix number.

Also, initialize other parts.

■ If the current matrix number in the state control table 16 points to one of the 2 individual matrices 19A to 19C, processing is performed according to the 7 individual matrices depending on the current state and the event that has occurred, and the current state is Set. At this time, if 7 trixes transition,
Set the common matrix number to the current matrix number.

■ During communication, repeat the processes from ■ to ■ above.

■ At the end of line use, status control table 162 Clear and end the process.

〔Effect of the invention〕

As explained above, according to the present invention, it is not necessary to develop two duplicate programs for the common parts of similar communication procedures, so it is possible to reduce the number of development steps. In addition, it is possible to save resources for storing programs, etc.
Programs that control state transitions can also be unified, making management easier.
