DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a server for transmitting data to a plurality of terminals and a data transmission method for transmitting data from the server to a plurality of terminals.

[0002]

2. Description of the Related Art In a system of this kind, which comprises a server and a plurality of terminals, and transmits data from the server to the terminal to be transmitted, if the number of terminals to be serviced is small, the server is one process. All terminals are serviced.

However, when the number of terminals is large, a method is adopted in which a terminal group is divided into a plurality of groups and one process on the server side is assigned to the groups.

[0004]

In such a system, a grouping table must be prepared in advance for all connected terminals.

[0005] In this case, in a system in which the number of terminals is increased and decreased relatively frequently, the terminal group assignment work must be performed frequently.

[0006] In addition, it is preferable that the terminal grouping be randomized as much as possible. Therefore, it is preferable to review the grouping of all terminals each time an extension or removal is performed. Is the actual situation.

An object of the present invention relates to management of a terminal group when a terminal is added / removed, and a server and data capable of automatically executing grouping of terminals without creating a terminal group management table in advance. It is intended to provide a transmission method.

[0008]

A transmission data queue corresponding to the terminal group number, a terminal transmission process for transmitting data to the terminal according to the terminal group number according to the transmission data queue, and the terminal group management based on a notification of a terminal state change from the terminal. Means for allocating the terminal group number to a terminal capable of transmitting data on a table, and means for transmitting transmission data to the terminal by referring to the terminal group management table and transmitting transmission data to the transmission queue. It is characterized by.

According to another aspect of the present invention, there is provided a data transmission method for transmitting data from a server to a plurality of terminals according to the present invention, based on an operation state and a non-operation state notification transmitted from the terminal to the server. The terminal name and the terminal group number are registered and deleted, and when transmitting data to the terminal, the terminal group number of the registered terminal is registered in a transmission data queue.

According to the present invention, a terminal status change notification from a terminal, for example, only a terminal that has received an operation status notification is registered in a terminal group management table, and a terminal status change notification, for example, a non-operation notification from the terminal side. In the initial state, the terminal name is not registered in the terminal group management table by deleting the terminal from the terminal group management table when there is a terminal group management table. , The management of the terminal group at the time of adding or removing a terminal can be facilitated.

[0011]

FIG. 1 is an example of a system configuration according to a first embodiment.

The server 1 of the present embodiment comprises terminals 61 and 6
2, 63, 64. The server 1 has business applications 11 and 12, which are application processes in the server 1. As a result of processing by the business applications 11, 12, the terminals 61, 62, 63,
Data transmission occurs to the 64.

Transmission data queue 21 of terminal group # 1
The transmission data queue 22 of the terminal group # 2 corresponds to the terminal transmission process 31 of the terminal group # 1 and the terminal transmission process 32 of the terminal group # 2, respectively. The business applications 11, 12 are terminals 61, 62, 6
When data is transmitted to 3, 64, the terminal refers to the terminal group management table 40, selects a transmission data queue corresponding to the destination terminal name, and registers the transmission data 20 in the queue.

The terminal transmission processes 31 and 32 transmit the transmission data 2 registered in the transmission data queues 21 and 22, respectively.
1 are sequentially read out and the designated destination terminals 61, 6
2, 63 and 64.

The terminal monitoring process 50 includes terminals 61 and 6
When the operating status change notification is received from 2, 63, 64,
The terminal group management table 40 is updated.

FIG. 2 shows an example of the structure of the transmission data 20.
It is composed of a data type 20s, a destination terminal name 20t, a data byte size 20b, and a transmission content 20d. Although it is possible to register a plurality of terminal names as the transmission destination terminal name 21t, here, one case is set for the sake of simplicity.

FIG. 3 shows a configuration example of the terminal group management table 40. In order to reduce the burden on the system administrator on the operation side, only the terminals that have been notified of the operation status from the terminals are registered, and when there is a non-operation notification from the terminal side, they are deleted. That is, in the expected state, no terminal name is registered. This method eliminates the need to create a terminal group management table in advance.

The terminal group management table 40 includes a registration number 400, a terminal name 401t of the # 1 record, a terminal group number 401g of the # 1 record, a terminal name 402t of the # 2 record, a terminal group number 402g of the # 2 record,
# 3 record terminal name 403t, # 3 record terminal group number 403g, # 4 record terminal name 404t, #
It is composed of four record terminal group numbers 404g and the like. Records without terminal names are empty records.

Next, a data transmission method according to the present invention with the above configuration will be described. This method is an example in which the processes of the business applications 11 and 12 refer to the terminal group management table 40 and register the transmission data in the transmission data queue 21 or 22 corresponding to the terminal group number.

FIG. 4 is a flowchart showing a terminal monitoring process 5 when a terminal status change notification from the terminal in this example, that is, an operation status notification or a non-operation status notification is received.
0 indicates operation.

First, as step S101, it is checked whether or not an operating state change notification has been received from the terminal. here,
If a notification of a change in the operating state has been received from the terminal 61, the terminal 62, the terminal 63, or the terminal 64, the process proceeds to step S102.
Proceed to, otherwise end.

In step S102, it is checked whether or not the notification content is a notification of "operating state". Notification content is "Operation status"
If so, the process proceeds to step S103; otherwise, the process proceeds to step S105.

In step S103, a terminal group number is calculated using a random number. That is, if the numerical value of the terminal group, that is, the number of terminal transmission processes is m, 1 to m
Generate a random number of positive integers up to. For example, in FIG.
Since the number of terminal transmission processes is two, the result of random number generation is one or two.

In step S104, the information of the corresponding terminal is registered in the terminal group management table 40. For example, if the terminal name is the terminal 62 and the random number generation result is 2,
It is assumed that the empty record in the terminal group management table 40 is the # 1 record.

In this case, # in the terminal status management table 40
In one record, the terminal 6 is assigned to the terminal name 401t of the # 1 record.
Write 2.

Next, the terminal group number 4 of the # 1 record
In 01g, the value of the random number generation result is written.

Next, the number of registered items 400 is set to +1 and the process ends.

If the corresponding terminal name has already been registered in the terminal group management table 40, the process ends without doing anything.

In step S105, it is checked whether or not the content of the notification is a "non-operating state" notification. Here, if the notification content is “non-operational state”, the process proceeds to S step S106, and if not, the process ends.

In step S106, the information of the corresponding terminal is deleted from the terminal group management table 40. It is checked whether the terminal name and the terminal 62 are already registered in the record of the terminal group management table 40. If the terminal name is terminal 6
If 1 is already registered and the record is the # 1 record, the terminal name 401t of the # 1 record is cleared, the terminal group number 401g of the # 1 record is cleared, and the number of registered items 400 is set to −1, It is the end.

Next, the operation of the business applications 11 and 12 when requesting transmission of transmission data to the terminal by the business applications 11 and 12 will be described with reference to the flowchart of FIG.

First, in step S201, the terminal group number to which the destination terminal belongs is checked with reference to the terminal group management table 40. That is, transmission data 2
Check the destination terminal name of 0. For example, assume that the terminal 62 is used.

Next, in step S202, transmission data is registered in the transmission data queue # corresponding to the terminal group number. The record of the terminal 62 is searched as the terminal name in the record of the terminal group management table 40. For example, if it is registered in the # 1 record, the terminal group number 401g of the # 1 record is obtained. Terminal group number 401g
The transmission data 20 is registered in the transmission data queue indicated by the value of.

For example, if the value of the terminal group number of the # 1 record is "2", the transmission data is registered in the transmission data queue 22 of the terminal group # 2, and the processing is ended.

The operation of the terminal transmission processes 31 and 32 for transmitting data to the terminal is shown in the flowchart of FIG.

First, in step S301, transmission data is extracted from the transmission data queue. For example, in the case of the terminal transmission process 32, the transmission data 20 is extracted from the transmission data queue 22 of the terminal group # 2.

Next, in step S302, it is checked whether or not the queue is empty.

Here, if the queue is empty, the process ends; otherwise, the process proceeds to step S303.

In step S303, the transmission data is transmitted to the terminal. That is, the destination terminal name 20t is obtained from the transmission data 20. The transmission data 20 is transmitted to the corresponding terminal, and the process returns to step 301.

As described above, according to the present embodiment, the following operation is achieved. That is, when the number of terminals is increased without adding the number of terminal transmission processes on the server side, the number of the added terminal is assigned by a random number when the operation status is notified from the terminal.

If the number of terminal transmission processes on the server side is added and the number of terminals is not changed, the terminal group number is assigned by a random number when the operation status is notified from the terminal.
Moreover, since the maximum value of the terminal group number is linked to the number of terminal transmission processes on the server side, the terminal group assignment is automatically changed.

Further, a terminal group is assigned when the operation status is notified from the terminal, so that an even group can be assigned to the operating terminals.

For example, in the case of the pre-allocation method, only the terminal previously allocated to the group # 1 operates, and when the other groups are not operating, the terminal transmission process on the server which is substantially activated Means only the process of terminal group # 1 and the other processes play. However, according to the present invention, a group of operating terminals is automatically allocated equally to all terminal transmission processes on the server side corresponding to the terminal group, so that the operator does not have to worry about the terminal group allocation. Can also operate the system efficiently.

Next, a second embodiment of the server according to the present invention will be described with reference to FIG.

In this embodiment, the same parts as those in FIG. 1 showing the configuration of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

In this embodiment, the business application process does not need to be aware of the terminal group number, but only registers it in the transmission data distribution queue 80.

The transmission data distribution process 70 is for transmitting the transmission data 20 registered in the transmission data distribution queue 80.
The terminal group number corresponding to the destination terminal name is obtained by referring to the terminal management table, and the transmission data is registered again in the transmission data queue corresponding to the terminal group number.

Next, referring to the flowchart shown in FIG. 8, the operation of the business applications 11 and 12 at the time of requesting data transmission to the terminal will be described. That is, step S401
As the transmission data distribution queue 8
Register 0 and end.

FIG. 9 shows the operation of the transmission data distribution process 70.

First, in step S501, the transmission data is extracted from the transmission data distribution queue. That is,
The transmission data 20 is extracted from the transmission data distribution queue 80.

Next, in step S502, it is checked whether the queue is empty. If the transmission data distribution queue 80 is empty, the process ends, otherwise, step S503.
Proceed to.

In step S503, the terminal name of the transmission destination is checked from the transmission data. That is, the destination terminal name 21t is obtained from the transmission data 20. For example, assume that the terminal 62 is used.

In step S504, the terminal group number of the destination terminal is checked with reference to the terminal group management table 40. That is, the terminal 62 is used as the destination terminal name registered in the record of the terminal group management table 40.
Find the record for For example, assume that the record is # 1. The terminal group number 401g of the # 1 record is obtained, and this value is 2.

Next, in step S505, the transmission data is registered in the transmission data queue # corresponding to the terminal group number. Register in the transmission data queue indicated by the value of the terminal group number. For example, if the terminal group number is 2,
It is registered in the transmission data queue 22 of the terminal group # 2, and returns to step S501.

According to the present embodiment described in detail above, the same effects as those of the first embodiment can be obtained, and the following effects can also be obtained. That is, the first embodiment is a method for making the business application aware of the terminal group number. However, the second embodiment has an advantage in system construction that the business application is not made aware of the terminal group number.
