Information communication system, intermediate server, and recording medium

An intermediate server that acts as a relay between an information processing apparatus located in a local area network and an external server located outside said local area network, the intermediate server comprising:

• a first registration control unit that transmits registration information regarding an application software service of said external server to said information processing apparatus on the basis of information received from said external server, and causes said information processing apparatus to execute a registration operation of pre-registering information for receiving said application software service in said information processing apparatus;
• a storage unit that stores a template that is based on said registration information, said template being a template for re-registration information that is for re-registering said application software service in said information processing apparatus;
• a detection unit that detects a change in network identification information regarding said intermediate server that is located in said local area network;
• and
• a second registration control unit that, when the change in said network identification information is detected, generates re-registration information that includes changed new network identification information regarding said intermediate server on the basis of said template, transmits said re-registration information to said information processing apparatus, and causes said information processing apparatus to execute a re-registration operation of re-registering said application software service.

A non-transitory computer-readable recording medium that records a program for causing a computer built into an intermediate server that acts as a relay between an information processing apparatus located in a local area network and an external server located outside said local area network to execute the steps of:

• a) transmitting registration information regarding an application software service of said external server to said information processing apparatus on the basis of information received from said external server, and causing said information processing apparatus to execute a registration operation of registering information for receiving said application software service in said information processing apparatus;
• b) storing a template that is based on said registration information, said template being a template for re-registration information that is for re-registering said application software service in said information processing apparatus;
• c) detecting a change in network identification information regarding said intermediate server that is located in said local area network;
• and
• d) when the change in said network identification information is detected, generating re-registration information that includes changed new network identification information regarding said intermediate server on the basis of said template, transmitting said re-registration information to said information processing apparatus, and causing said information processing apparatus to execute a re-registration operation of re-registering said application software service.
