Abstract

A processing terminal has a communication unit that establishes a connection with a server and conducts communication; a processing unit that executes predetermined processing based on information acquired from the server through the communication; a disconnection detecting unit that detects a disconnection of the connection; and a reconnecting unit that repeatedly attempts a reconnection with the server at first timing that is random and meets conditions that an expected value of the interval of the attempts is a predetermined certain value in a case where a disconnection of the connection is detected.

Claims

1. A processing terminal comprising:

a communication unit that establishes a connection with a server and conducts communication;

a processing unit that executes predetermined processing based on information acquired from the server through the communication;

a disconnection detecting unit that detects a disconnection of the connection; and

a reconnecting unit that attempts a reconnection with the server at first timing that occurs with random timing within a period of time that repeats and has a predetermined length in a case where a disconnection of the connection is detected.

3. The processing terminal according to claim 1, wherein the reconnecting unit attempts a reconnection with the server at predetermined second timing before the initial first timing occurs after a disconnection of the connection is detected.

5. The processing terminal according to claim 1, wherein the reconnecting unit sets the predetermined length based on connection control information acquired from the server.

2. A processing terminal comprising:

a communication unit that establishes a connection with a server and conducts communication;

a processing unit that executes predetermined processing based on information acquired from the server through the communication;

a disconnection detecting unit that detects a disconnection of the connection; and

a reconnecting unit that attempts a reconnection with the server at first timing that occurs at an interval of random lengths that do not exceed an upper limit having a predetermined length.

4. The processing terminal according to claim 2, wherein the reconnecting unit attempts a reconnection with the server at predetermined second timing before the initial first timing occurs after a disconnection of the connection is detected.

6. The processing terminal according to claim 2, wherein the reconnecting unit sets the predetermined length based on connection control information acquired from the server.

7. A processing method comprising:

establishing a connection with a server and conducting communication;

executing predetermined processing based on information acquired from the server through the communication;

detecting a disconnection of the connection; and

attempting a reconnection with the server at first timing that occurs with random timing within a period of time that repeats and has a predetermined length, or at first timing that occurs at an interval of random lengths that do not exceed an upper limit having a predetermined length, in a case where a disconnection of the connection is detected.
