Transfer management server, termainal, and programs executed thereby

A transfer management server which manages transfer of service being used by a transferring source terminal to a transferring destination terminal, comprising:

• a notification destination information storage unit which stores notification destination information of at least one service server including a service server that provides said service;
• a transfer management unit which receives, from said transferring source terminal and said transferring destination terminal, a notification of transfer of service with a terminal ID of the terminal in question and an identification ID which is unique between said transferring source terminal and said transferring destination terminal;
• a terminal change information storage unit which, when receiving a notification of transfer of said service, stores a pair of the terminal ID of said transferring source terminal and said identification ID and a pair of the terminal ID of said transferring destination terminal and said identification ID so as to correspond to each other as terminal change information;
• and
• a service transfer notification transmission unit which transmits a service transfer notification with the terminal ID of said transferring source terminal and the terminal ID of said transferring destination terminal to said service server stored in said notification destination information storage unit by referring to said terminal change information storage unit.

A terminal which uses service provided by a service server, comprising:

• a terminal ID storage unit which stores a terminal ID applied to each terminal;
• at least one client application for transmitting said terminal ID to said service server to make a service request;
• and
• a service transfer management unit which transmits said terminal ID of the terminal in question and an identification ID which is unique with respect to the other terminal as a service transferring source or a service transferring destination to said transfer management server to notify transfer of service.

A program stored on a non-transitory medium to be executed on a transfer management server that manages transfer of service being used by a transferring source terminal to a transferring destination terminal, which causes said transfer management server to execute:

• a processing of reading notification destination information of at least one service server including a service server that provides said service from a notification destination information storage unit,
• a processing of receiving, from said transferring source terminal and said transferring destination terminal, a notification of transfer of service with a terminal ID of the terminal in question and an identification ID which is unique between said transferring source terminal and said transferring destination terminal,
• a processing of recording a pair of the terminal ID of said transferring source terminal and said identification ID and a pair of the terminal ID of said transferring destination terminal and said identification ID so as to correspond to each other as terminal change information in a terminal change information storage unit when receiving a notification of transfer of said service, and
• a processing of referring to said terminal change information storage unit to transmit a service transfer notification with the terminal ID of said transferring source terminal and the terminal ID of said transferring destination terminal to said service server read from said notification destination information storage unit.
