Information processing system, user terminal, and electronic apparatus

1. An information processing system, comprising:

a user terminal; and

an electronic apparatus communicably connected to the user terminal,

the user terminal including

a memory device configured to store a connection setting value and a manager service, the connection setting value being used to connect to a service in an external network by an extended application of the electronic apparatus, the manager service causing the user terminal to send the connection setting value to the electronic apparatus,

a communication device configured to receive first communication from the electronic apparatus, the first communication being for searching for the manager service, and

a controller circuitry configured to

if the user terminal has the connection setting value corresponding to the extended application of the first communication, control the communication device to send second communication to the electronic apparatus when the communication device receives the first communication, the second communication indicating that the manager service is ready to send the connection setting value to the electronic apparatus, and

control the communication device to send fourth communication to the electronic apparatus when the communication device receives third communication from the electronic apparatus, the third communication requesting to send the connection setting value, the fourth communication sending the connection setting value,

the electronic apparatus including

a memory device configured to store the extended application,

a communication device configured to send the first communication, in which the extended application is specified by the electronic apparatus, when the electronic apparatus starts the extended application, and

a controller circuitry configured to

where the communication device receives the second communication from one or more manager services, control to display a list of the one or more manager services that sent the second communication,

control the communication device to send the third communication to a manager service displayed on the list and selected by a user, and

where the connection setting value is received via the fourth communication, control the extended application to execute fifth communication, the fifth communication connecting to the service in the external network by using the connection setting value.

2. The information processing system according to claim 1 , wherein

the controller circuitry of the electronic apparatus is configured to, after the fifth communication, delete, from the electronic apparatus, information of the second communication received from the one or more user terminals.

3. The information processing system according to claim 1 , wherein

the connection setting value includes setting information of a proxy server and authentication information, the proxy server being configured to execute communication with the service in the external network as a proxy of the electronic apparatus, the authentication information being used to log in to the service in the external network.

4. A user terminal communicably connected to an electronic apparatus,

the user terminal including

a memory device configured to store a connection setting value and a manager service, the connection setting value being used to connect to a service in an external network by an extended application of the electronic apparatus, the manager service causing the user terminal to send the connection setting value to the electronic apparatus,

a communication device configured to receive first communication from the electronic apparatus, the first communication being for searching for the manager service, and

a controller circuitry configured to

if the user terminal has the connection setting value corresponding to the extended application of the first communication, control the communication device to send second communication to the electronic apparatus when the communication device receives the first communication, the second communication indicating that the manager service is ready to send the connection setting value to the electronic apparatus, and

control the communication device to send fourth communication to the electronic apparatus when the communication device receives third communication from the electronic apparatus, the third communication requesting to send the connection setting value, the fourth communication sending the connection setting value,

the electronic apparatus including

a memory device configured to store the extended application,

a communication device configured to send the first communication, in which the extended application is specified by the electronic apparatus, when the electronic apparatus starts the extended application, and

a controller circuitry configured to

where the communication device receives the second communication from one or more manager services, control to display a list of the one or more manager services that sent the second communication,

control the communication device to send the third communication to a manager service displayed on the list and selected by a user, and

where the connection setting value is received via the fourth communication, control the extended application to execute fifth communication, the fifth communication connecting to the service in the external network by using the connection setting value.

5. An electronic apparatus communicably connected to a user terminal,

the user terminal including

a memory device configured to store a connection setting value and a manager service, the connection setting value being used to connect to a service in an external network by an extended application of the electronic apparatus, the manager service causing the user terminal to send the connection setting value to the electronic apparatus,

a communication device configured to receive first communication from the electronic apparatus, the first communication being for searching for the manager service, and

a controller circuitry configured to

if the user terminal has the connection setting value corresponding to the extended application of the first communication, control the communication device to send second communication to the electronic apparatus when the communication device receives the first communication, the second communication indicating that the manager service is ready to send the connection setting value to the electronic apparatus, and

control the communication device to send fourth communication to the electronic apparatus when the communication device receives third communication from the electronic apparatus, the third communication requesting to send the connection setting value, the fourth communication sending the connection setting value,

the electronic apparatus including

a memory device configured to store the extended application,

a communication device configured to send the first communication, in which the extended application is specified by the electronic apparatus, when the electronic apparatus starts the extended application, and

a controller circuitry configured to

where the communication device receives the second communication from one or more manager services, control to display a list of the one or more manager services that sent the second communication,

control the communication device to send the third communication to a manager service displayed on the list and selected by a user, and

where the connection setting value is received via the fourth communication, control the extended application to execute fifth communication, the fifth communication connecting to the service in the external network by using the connection setting value.
