Abstract

A push-type information transmission device is provided with a determination unit that determines the number of clients at transmission destinations of push transmission information in each of a plurality of chronologically continuous periods on the basis of at least response delay distribution data which is a probability distribution indicating the ratio of responses to information to the time elapsed since transmission of the information, and allowable band data indicating the allowable amount of information transfer.

First claim

The invention claimed is:

1. A push-type information transmission device comprising:
a determination unit
that determines a number of transmission destination clients of push transmission information in each of a plurality of chronologically continuous periods based on at least response delay distribution data that is a probability distribution indicating a ratio of responses to information in relation to time elapsed since transmission of the information and allowable band data indicating allowable amount of information transfer; and

a transmission unit that transmits a push-type information based on the number of clients determined by the determination unit,
wherein the response delay distribution data is a probability distribution indicating a response ratio of clients in relation to time elapsed since transmission of push transmission information that induces responses from the clients as transmission targets to the clients, and
the allowable band data indicates variation in the amount of information transfer per unit time that is allowable in relation to time elapsed of a communication network that is connected to the push-type information transmission device.

2. The push-type information transmission device according to claim 1 ,
wherein the plurality of periods include a first period and a second period that is continuous from the first period and after the first period;
the determination unit specifies a first response ratio during the second period in response to transmission during the first period from the response delay distribution data;
the determination unit calculates an amount of information transfer based on the number of transmission destination clients during the first period and the first response ratio;
the determination unit specifies a second response ratio during the second period in response to transmission during the second period from the response delay distribution data;
the determination unit specifies the allowable amount of information transfer during the second period from the allowable band data; and
the determination unit determines the number of transmission destination clients during the second period at least based on the calculated amount of information transfer, the second response ratio, and the calculated amount of information transfer.

3. The push-type information transmission device according to claim 2 ,
wherein the determination unit simulates the number of transmission destination clients using a combination of one of a plurality of kinds of the response delay distribution data and one of a plurality of kinds of the allowable band variation data.

4. The push-type information transmission device according to claim 1 ,
wherein the push transmission unit determines priority based on information indicating a priority regarding order of transmission of the push transmission information to the transmission destination clients or a past transmission performance, and
the push transmission unit transmits the push-type information based on the priority.

5. The push-type information transmission device according to claim 4 ,
wherein the determination unit simulates the number of transmission destination clients using a combination of one of a plurality of kinds of the response delay distribution data and one of a plurality of kinds of the allowable band variation data.

6. The push-type information transmission device according to claim 1 ,
wherein the determination unit simulates the number of transmission destination clients using a combination of one of a plurality of kinds of the response delay distribution data and one of a plurality of kinds of the allowable band variation data.

7. The push-type information transmission device according to claim 6 ,
wherein the determination unit determines the number of transmission destination clients such that push-type information transmission completes within closest time to average delay time that is time from starting to finishing the push-type information transmission.

8. The push-type information transmission device according to claim 1 ,
wherein the determination unit outputs the number of transmission destination clients.

9. The push-type information transmission device according to claim 1 ,
wherein the plurality of periods include a first period and a second period that is continuous from the first period and after the first period;
the determination unit specifies a first response ratio during the second period in response to transmission during the first period from the response delay distribution data;
the determination unit calculates an amount of information transfer based on the number of transmission destination clients during the first period and the first response ratio;
the determination unit specifies a second response ratio during the second period in response to transmission during the second period from the response delay distribution data;
the determination unit specifies the allowable amount of information transfer during the second period from the allowable band data; and
the determination unit determines the number of transmission destination clients during the second period at least based on the calculated amount of information transfer, the second response ratio, and the calculated amount of information transfer.

10. The push-type information transmission device according to claim 9 ,
wherein the push transmission unit determines priority based on information indicating a priority regarding order of transmission of the push transmission information to the transmission destination clients or a past transmission performance, and
the push transmission unit transmits the push-type information based on the priority.

11. The push-type information transmission device according to claim 10 ,
wherein the determination unit simulates the number of transmission destination clients using a combination of one of a plurality of kinds of the response delay distribution data and one of a plurality of kinds of the allowable band variation data.

12. The push-type information transmission device according to claim 9 ,
wherein the determination unit simulates the number of transmission destination clients using a combination of one of a plurality of kinds of the response delay distribution data and one of a plurality of kinds of the allowable band variation data.

13. The push-type information transmission device according to claim 1 ,
wherein the determination unit simulates the number of transmission destination clients using a combination of one of a plurality of kinds of the response delay distribution data and one of a plurality of kinds of the allowable band variation data.

14. A push-type information transmission method comprising:
determining a number of transmission destination clients of push transmission information in each of a plurality of chronologically continuous periods based on at least response delay distribution data that is a probability distribution indicating a ratio of responses to information in relation to time elapsed since transmission of the information and allowable band data that indicates allowable amount of information transfer, and
transmitting a push-type information based on the determined number of clients,
wherein the response delay distribution data is a probability distribution indicating a response ratio of clients in relation to time elapsed since transmission of push transmission information that induces responses from the clients as transmission targets to the clients, and
the allowable band data indicates variation in the amount of information transfer per unit
